Despite these efforts, PTA programs experience an attrition rate of nearly 20%, which imposes significant costs on students, programs, and institutions. The goal of this study was to assess whether learning outcomes in a neurorehabilitation course could be enhanced through the use of Team-Based Learning (TBL). This research utilized a quantitative, quasi-experimental, ex post facto design to evaluate the effectiveness of TBL. While TBL is known to foster self-efficacy, self-directed learning, and teamwork skills, its impact on student achievement of learning outcomes remains unclear. The primary research question of this study was whether students in a neurorehabilitation course taught using TBL would show improved learning outcomes on in-class examinations or on the National Physical Therapy Examination-Physical Therapist Assistant (NPTE-PTA), compared to students who received the same course in a traditional lecture-based format. To address this, two groups of students enrolled in the course during nonconsecutive years were assessed for their learning outcomes. The analysis revealed no significant differences in examination scores or NPTE-PTA Neuromuscular and Neurological Systems scores between the two groups, even when controlling for pre-course Grade Point Average (GPA). The findings suggest that TBL is at least as effective as lecture-based instruction in achieving student learning outcomes in the neurorehabilitation course. Further research is needed to explore the optimal timing of TBL implementation within PTA programs and to determine whether the non-academic benefits of TBL, such as improved teamwork and self-efficacy, justify its inclusion in PTA education. --- #### An In-Depth Evaluation of the X and Y Axes in Misinformative Graphs **Authors:** John Mwangi, Amina Mohamed | **Affiliation:** University of Nairobi, Kenya **Pages:** 23-32 | **Published:** 2024/11/30 **URL:** https://www.ijama.in/papers?paper=An+In-Depth+Evaluation+of+the+X+and+Y+Axes+in+Misinformative+Graphs | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1759771703_IJAMANOV243.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=An+In-Depth+Evaluation+of+the+X+and+Y+Axes+in+Misinformative+Graphs | **Publication Year:** 2024 | **Volume/Issue:** Volume 1, Issue 3, Nov 2024 **Keywords:** Misinformation, Graph Manipulation, Data Visualization, X Axis, Y Axis, Cognitive Bias, Data Representation, Ethical Standards, Visual Deception, Data Integrity **Abstract:** The use of graphs to convey information has become ubiquitous across various domains, including scientific research, journalism, and social media. However, the potential for graphs to mislead or distort the message they intend to communicate is a significant concern. This study focuses on evaluating the X and Y axes of misinformative graphs, analyzing how these key components can be manipulated to distort data representation. The X and Y axes, which are fundamental to a graph�s structure, play a crucial role in shaping the viewer's interpretation of data. Through a comprehensive review of examples from various fields, this research identifies common techniques used to manipulate the scales, intervals, and labeling on both axes to exaggerate or downplay trends, correlations, or differences. The study also explores the cognitive biases that may lead to misinterpretation of such graphs and the ethical implications of presenting misleading visual data.By providing a systematic framework for identifying and understanding these manipulations, this paper aims to equip readers with the skills to critically evaluate graphs and ensure that data is represented in a truthful and transparent manner. The findings highlight the importance of accurate graph design and the need for greater awareness of the potential for visual data to be used in deceptive ways, calling for more robust guidelines and ethical standards in data visualization practices. --- #### Effectiveness and Moderators of Computer Based Health Education in Adults: A Systematic Review of Meta-Analytic Studies **Authors:** Sushma R.

In recent years, the use of digital platforms for health education has become more prevalent, particularly due to their accessibility, scalability, and convenience. However, the actual impact of these interventions on health knowledge, behavior change, and health outcomes remains under-explored. This review consolidates findings from several meta-analytic studies to identify the key determinants of successful computer-based health education programs for adults. The analysis focuses on various moderators that influence the effectiveness of these interventions, including the type of health behavior targeted, the delivery method, the population characteristics (e.g., age, gender, educational background), and the duration of the intervention. The results highlight that computer-based health education can be an effective tool in promoting health literacy and behavior changes in adults, especially when tailored to specific needs and supported by appropriate instructional design. However, certain factors, such as the complexity of the health topic, the level of interactivity, and the availability of support systems, play significant roles in determining the success of these interventions. This review provides insights into the strengths and limitations of computer-based health education and offers recommendations for future research and practical applications in health promotion. --- #### Unpacking the Triple Jump in Problem Based Learning: Principles and Practices for Designing Assessment to Ensure Curriculum Alignment **Authors:** R.

This paper analyzes the Triple Jump Assessment (TJA), implemented as both a formative and summative evaluation tool in the first year of an undergraduate dental program. The analysis deconstructs TJA across critical domains, including management and coordination, assessment design and item development, administration, and ongoing review for refinement and modification. Four core principles for designing TJA to ensure constructive alignment in a PBL curriculum are identified: collaborative assessment design as a collective faculty effort; fostering shared understanding of learning, teaching, and assessment between faculty and students; emphasizing continuous review to uphold validity and reliability; and prioritizing student learning throughout the assessment process. These insights highlight the potential of TJA to align assessments with curriculum goals effectively, supporting meaningful student learning outcomes in problem-based educational settings. --- ### Issue 4 — Dec 2024 — https://www.ijama.in/archives.php?volume=1&issue=4 #### Utilizing Thermography and Convolutional Neural Networks for the Detection of Mechanical Faults in Induction Motors and Gearbox Wear **Authors:** A.

This study presents a diagnostic approach for identifying various faults in an electromechanical system using infrared thermography and a convolutional neural network (CNN). The experiments involved testing the motor and gearbox under different conditions. The induction motor was evaluated in four states: healthy, with a broken bar, a damaged bearing, and misalignment. The gearbox was assessed under three conditions: healthy gears, 50% wear, and 75% wear. Faults were introduced through controlled machining operations. Data augmentation techniques, such as mirroring and brightness variation, were applied to enhance the dataset. Ablation studies were conducted, and a CNN with a simplified architecture was designed. The model achieved a precision of 98.53%, accuracy of 98.54%, recall of 98.65%, and F1-Score of 98.55%. These results demonstrate that the combination of infrared thermography and deep learning effectively detects faults across multiple components of an electromechanical system. --- #### Predicting Loss of Consciousness Events Using Natural Language Processing and Deep Learning on Emergency Department Text Records **Authors:** Joao dos Santos, S.

However, extracting useful and actionable information from unstructured clinical text remains a significant challenge. This study addresses this issue by applying natural language processing (NLP) techniques to extract injury-related variables and classify trauma patients based on the presence of loss of consciousness (LOC). A dataset of 23,308 trauma patient EMRs, comprising both pre-diagnosis and post-diagnosis free-text notes, was analyzed using a bilingual (English and Korean) pretrained RoBERTa model. The patients were grouped into four categories based on LOC and head trauma. To mitigate class imbalance in LOC labeling, deep learning models were trained with weighted loss functions, achieving an area under the curve (AUC) of 0.91. Local Interpretable Model-agnostic Explanations (LIME) analysis further highlighted the model's ability to identify key terms associated with head injuries and consciousness. The results suggest that NLP can accurately identify LOC in trauma patients EMRs, with the weighted loss functions effectively addressing class imbalances. These findings pave the way for developing AI tools that can enhance trauma care and clinical decision-making --- #### Exploring DFT-Based Techniques for Harmonic Phase Estimation, Transformation, and Synthesis **Authors:** S.

The waveform shapes of these signals provide valuable insights into the physical phenomena that generate them, making accurate estimation and modeling of these parameters crucial. While much attention has been given to frequency and magnitude estimation, phase estimation and modeling have received comparatively less focus in the literature. This paper addresses the accurate estimation of phase using Discrete Fourier Transform (DFT) techniques across six different scenarios involving two DFT-based filter banks and three distinct window functions. It demonstrates that phase estimation bias is less than 0.001 radians when the signal-to-noise ratio (SNR) is 2.5 dB or higher. By comparing the performance with the Cram�r-Rao lower bound (CRLB), it is shown that one specific window function offers significant practical benefits by closely approximating the CRLB under favorable signal conditions while minimizing performance deviation under less favorable conditions. Additionally, this paper introduces a shift-invariant phase-related feature that captures the harmonic phase structure. This feature forms the basis for a new signal processing paradigm that simplifies the parametric modeling, transformation, and synthesis of harmonic signals, aiding in the understanding and reverse engineering of the phasegram. The theoretical framework and experimental results are presented in a reproducible manner, with code provided to facilitate the replication of results and support further research --- #### Predicting the Biodegradability of Base Oils Using Data Mining Techniques **Authors:** Ahmadou B.

Both continuous numeric prediction models and discrete classification models were evaluated, with a focus on enhancing prediction accuracy. Results indicate that numeric prediction models outperform classification models in identifying highly biodegradable oils, providing more precise biodegradability estimates. Among the tested classification techniques, most achieved high prediction accuracy, except for Memory-Based Reasoning and Decision Trees. However, Decision Trees proved instrumental in identifying the most critical predictors of biodegradability. A simplified classification rule derived from these predictors demonstrated robust classification performance, efficiently categorizing base oils into low or high biodegradability classes. Additionally, continuous modeling techniques provided refined precision for predicting biodegradability within the high category. These findings highlight the complementary roles of classification and numeric prediction models in biodegradability assessment, offering a practical framework for environmental and industrial applications. --- ## Volume 2 (2025) ### Issue 1 — Jan 2025 — https://www.ijama.in/archives.php?volume=2&issue=1 #### Optimized Interactive Techniques for Digital Data Compression **Authors:** John K.

This paper explores an approach that incorporates prior knowledge of the source or of a source correlated to the one being compressed to significantly enhance compression efficiency. By utilizing this prior knowledge, the compression process can shift from relying solely on the source's entropy to leveraging conditional entropy. This substitution establishes a new theoretical limit for compression, enabling substantial improvements in performance. Interactive data compression involves incorporating a degree of interaction between the compressor and the decompressor, especially when data transmission is involved. This interaction facilitates the more effective use of shared prior knowledge about the source, resulting in greater compression efficiency. This paper reviews existing studies that have adopted interactive approaches to data compression and examines the potential benefits and challenges associated with these methods. The findings highlight the promise of conditional compression in achieving enhanced data transmission efficiency and suggest directions for future research in interactive data compression strategies. --- #### Enhancing Programming Learning Through the Integration of Emerging Technologies and Established Tools **Authors:** Amadou S.

Our group has contributed significantly to this field with the development of tools such as VIP, SICAS, OOP-Anim, SICAS-COL, and H-SICAS. While these tools have shown some positive results, their impact on reducing the difficulties of weaker students has not been as substantial as expected. These students often require more robust support to motivate and engage them in learning, both inside and outside the classroom. With the advent of new technologies, we believe that the integration of various solutions can play a crucial role in overcoming these challenges. This paper evaluates the features, strengths, and weaknesses of the tools developed by our group, identifying areas for improvement. Based on these insights, we propose the development of a new environment that integrates multiple pedagogical approaches, resources, tools, and technologies to support programming learning. The new environment, currently under development, will enable students to review content and lessons through video and screen captures. It will also incorporate collaborative task support, fostering teamwork and collaboration among students. Additionally, the platform will facilitate the creation of diverse learning models (learning objects) for the same subject, allowing for personalized learning paths tailored to each student's knowledge level, needs, and preferred learning styles. Learning sequences will serve as study organizers, structured around a cognitive skills taxonomy. While the environment primarily aims to support students with greater difficulties, it will also provide resources for advanced topics such as software engineering techniques, object orientation, and event programming, to promote the learning progress of all students --- #### Defining Graph Extremities Using Search Algorithms **Authors:** Mole-Dagbani, Ga-Dangme | **Affiliation:** Department of Electrical Engineering, University of Ghana, Accra, Ghana **Pages:** 21-28 | **Published:** 2025/01/30 | **DOI:** https://doi.org/10.5281/zenodo.17322806 **URL:** https://www.ijama.in/papers?paper=Defining+Graph+Extremities+Using+Search+Algorithms | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1759771056_JAN%2025IJAMA3.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17322806, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17322806 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Defining+Graph+Extremities+Using+Search+Algorithms | **Publication Year:** 2025 | **Volume/Issue:** Volume 2, Issue 1, Jan 2025 **Keywords:** Graph search algorithms, extremities, chordal graphs, MLS (Minimum Lexicographic Search), MLSM (Minimum Lexicographic Search on Modified graphs), minimal separators, total ordering, vertex properties, graph traversal, graph theory, network analysis **Abstract:** Graph search algorithms have proven to be powerful tools for exploring the structure of graphs, with applications ranging from computer science and artificial intelligence to bioinformatics and network analysis. These algorithms are designed to traverse or search through graphs in efficient ways, exploiting specific graph properties like graph extremities to optimize the process. Extremities in graphs typically refer to vertices or edges that have unique properties or positions within the graph's structure, such as the leaves in a tree or simplicial vertices in chordal graphs.A chordal graph is a special class of graph in which every cycle of four or more vertices has a chord, a shortcut edge that connects two non-adjacent vertices within the cycle. The leaves of a tree, on the other hand, are the vertices with only one edge connecting them to the rest of the graph. These extremities play a significant role in many graph search algorithms, as they are often the starting points or stopping points for various search processes.In this paper, we delve deeper into the properties of a particular vertex within the context of two well-known graph search algorithms: MLS (Minimum Lexicographic Search) and MLSM (Minimum Lexicographic Search on Modified graphs). These algorithms have been collectively expressed as two generic approaches to graph search, making it easier to implement and study their behavior. We specifically focus on the vertex that is assigned the number 1 by these two algorithms one on chordal graphs and the other on arbitrary graphs.Our investigation reveals that this vertex holds a special place within the graphs structure. The vertex numbered 1 by MLS on a chordal graph and MLSM on any graph exhibits properties that make it an extremity of the graph. This means that the vertex has significant structural influence on the graph, often acting as a key point in the exploration process. Additionally, the paper highlights a particularly interesting and remarkable property of the minimal separators surrounding this vertex. Minimal separators are subsets of vertices that, when removed, disconnect the graph into two or more disconnected components. In the case of the vertex numbered 1, the minimal separators in its neighborhood are totally ordered by inclusion. This means that each minimal separator in the neighborhood is either completely contained within or contains the others in the set.This observation of total ordering by inclusion among minimal separators is significant because it suggests that these separators exhibit a well-defined hierarchical structure that can be leveraged for more efficient graph analysis and search operations. Understanding this ordering can lead to new insights and improvements in the design of graph search algorithms, particularly when working with chordal and arbitrary graphs. By using this knowledge, it may be possible to optimize the search process further, making it both faster and more reliable in a variety of applications. In conclusion, the properties of the vertex numbered 1 by MLS and MLSM, and the total ordering of the minimal separators around it, offer valuable insights into the nature of extremities within graphs. These findings can contribute to the development of more efficient and effective graph search algorithms, ultimately improving our ability to analyze complex networks and graph-based structures in various domains --- #### The Effect of Leaders Personality on Employees Job Satisfaction: A Case Study of Commercial Bank of Ethiopia, Shashemene. **Authors:** Sintayehu Gurmessa Chimedessa | **Affiliation:** Professor Arvinder Singh Chawla, Guru Kashi University **Pages:** 29-37 | **Published:** 2025/01/30 | **DOI:** https://doi.org/10.5281/zenodo.17322919 **URL:** https://www.ijama.in/papers?paper=The+Effect+of+Leaders+Personality+on++Employees+Job+Satisfaction%3A+A+Case++Study+of+Commercial+Bank+of+Ethiopia%2C++Shashemene. | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1759771077_JAN%2025IJAMA4.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17322919 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=The+Effect+of+Leaders+Personality+on++Employees+Job+Satisfaction%3A+A+Case++Study+of+Commercial+Bank+of+Ethiopia%2C++Shashemene. | **Publication Year:** 2025 | **Volume/Issue:** Volume 2, Issue 1, Jan 2025 **Keywords:** job satisfaction, agreeableness, consciousness, extraversion, openness and neuroticism. **Abstract:** This study's primary goal was to investigate how leaders' personalities affected their subordinates' job satisfaction at the Commercial Bank of Ethiopia. The study used primary sources of data, quantitative methods, and a descriptive research design. The data used in this study was collected from professional staff members of the Commercial Bank of Ethiopia's head office and two branches. Job satisfaction and a multifactor leadership questionnaire were employed. 112 of the 119 surveys that were distributed were collected and used for additional analysis. Additionally, all collected data were processed using SPSS version 25 and subjected to regression analysis, correlation analysis, and descriptive statistics (mean, standard deviation). The finding of this study indicated that there was no significant relationship between the personality of the leader and job satisfaction, and the highest mean score showed that employees favored agreeableness and consciousness personality. Also, the regression analysis showed that only neuroticism personality of leaders’ correlates with job satisfaction. The other independent variables were found to have no effect on job satisfaction. The researcher recommended the bank, to use five of the leader personality simultaneously to better satisfy employees’ working under their control. Leaders of the bank should work on creating a platform for employees to use their skills and abilities creatively to encourage innovation, develop a robust employee training and development program to help employees to improve their performance. Finally the researcher recommends the bank to work hard in conducting a continuous assessment of job satisfaction surveys and takes corrective action to improve and bring the success of their employees in their expertise. --- #### The Impact of Metacognition on Student Learning Outcomes **Authors:** Ankit R.

This survey provides a structured review of the theoretical foundations, architectural patterns, reasoning strategies, and real-world deployments of agentic AI. We examine the core components of contemporary agentic frameworks — perception, reasoning engines, memory hierarchies, planning modules, and tool interfaces — drawing on recent literature spanning large language model (LLM)-based agents, multi-agent systems, embodied agents, and hybrid symbolic-neural approaches. Advanced reasoning paradigms including Chain-of-Thought (CoT), Tree-of-Thought (ToT), ReAct, Reflexion, and Monte Carlo Tree Search (MCTS)-augmented planning are analysed alongside the emerging challenges of alignment, safety, and scalability. Real-world applications across software engineering, scientific discovery, healthcare, robotics, enterprise automation, and education are surveyed, and critical open problems are identified. This survey is intended as a reference architecture for researchers and practitioners engaged in the design, evaluation, and deployment of agentic AI systems. --- ### Issue 2 — Feb 2025 — https://www.ijama.in/archives.php?volume=2&issue=2 #### Commitment And Psychological Wellbeing in Long Distance Relationship and Proximal Relationship : A Comparative Study **Authors:** Riya Nagar , Dr. Hamsa N.

They occur when seismic forces release energy stored in the Earth's crust, generating tremors that can last from seconds to minutes, and can trigger landslides, tsunamis, and fires. To mitigate earthquake damage, innovative solutions are necessary. Earthquake-resistant construction techniques have emerged as effective measures. Base isolation, which decouples a structure from the ground, reducing force transmission, is one such technique. Other methods include seismic retrofitting to strengthen existing structures, using reinforced materials like reinforced steel and fiber-reinforced polymers, and incorporating shock-absorbing systems such as viscous fluid dampers and lead-rubber bearings. Additionally, flexible foundations that allow structures to move with seismic forces, advanced framing techniques like special moment frames and buckling-restrained braced frames, are being utilized. Furthermore, a promising alternative for base isolation is the use of scrap tyre rubber pads (STRP), an eco-friendly, low-cost approach that repurposes waste materials, providing sustainable waste management and affordable seismic protection. By exploring these innovative solutions, helps in improving seismic resilience and saving lives. Effective adoption of these techniques can significantly reduce earthquake damage, protecting infrastructure, and ensuring public safety.

(O2) To analyze 15 literature reviews related to flood-prone areas in Kerala. (O3) To visualize Kerala�s spatial data and Urban Design Development, we propose a flood relief shelter design. Methodology: To identify flood-prone areas via GIS-based spatial data analysis, assess extant research studies on?flood resilience, and determine potential GIS-driven flood shelter locations based on urban vulnerability mapping. This study incorporated a vernacular flood-adaptive architecture?in shelter design. Using ArcGIS Pro and 2011 census data, this study mapped flood vulnerability zones, assessed encroachment patterns, loss of green cover, and disaster resilience policies, and proposed site selection criteria for flood shelters. Research Questions: This study seeks to answer the following key questions: What are the primary causes of flooding in Kerala? Which vernacular architectural solutions exist for flood resilience? How can GIS mapping optimize the selection of flood shelter sites? Methods and results: Creating Aluva, Kochi, and Kothamangalam flood inundation GIS Mapping using ArcGIS Pro, visualize maps showing the sustainable indicators: Environmental impact and changes (encroachment of water bodies, loss of green cover and policies for conservation) and Natural calamities and resilience (Flood frequencies, economic loss and recovery, and community resilience and government interventions) and propose a flood relief shelter for flood-prone areas. Conclusion/Limitations: Literature reviews revealed gaps in current flood mitigation policies, emphasizing the need for resilient, amphibious, and elevated housing models.

This paper examines the structural, affective, and epistemic consequences of Nazrul's Persian-Urdu interpolations through a Quantum-Semiotic lens, investigating how these translinguistic components work as superpositional signifiers that elude monolingual collapse. The paper then utilises Bakhtinian heteroglossia, Peircean abductive semiosis, and Foucaultian discourse analysis to situate Nazrul's linguistic practice within the larger Indo-Persianate epistemic regime. Finally, this paper theorises Persian and Urdu not as singular linguistic influences but as entangled quantum-lexical states destabilising linear Bengali literary historiography and generating a bifurcated aesthetic consciousness swinging between the Persianate cosmopolis and the nascent Bengali national imaginary. --- ### Issue 5 — May 2025 — https://www.ijama.in/archives.php?volume=2&issue=5 #### Decoding Sleep: Leveraging Machine Learning for Precision Insomnia Classification **Authors:** Salil Choudhary, Tushar Kheterpal, Shivam Verma, Manoj Kumar | **Affiliation:** Department of Computer Engineering, Delhi Technological University, Delhi, India ,?Professor, Department of Computer Engineering, Delhi Technological University, Delhi, India **Pages:** 1-14 | **Published:** 2025/05/30 | **DOI:** https://doi.org/10.5281/zenodo.17519213 **URL:** https://www.ijama.in/papers?paper=Decoding+Sleep%3A+Leveraging+Machine+Learning+for+Precision+Insomnia+Classification | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1759768792_May%2025IJAMA1.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17519213, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17519213 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Decoding+Sleep%3A+Leveraging+Machine+Learning+for+Precision+Insomnia+Classification | **Publication Year:** 2025 | **Volume/Issue:** Volume 2, Issue 5, May 2025 **Abstract:** Sleep disorders such as insomnia and sleep apnoea are pervasive health conditions that negatively impact both physical well-being and cognitive function. Despite their widespread occurrence, many individuals remain undiagnosed due to the high cost, inconvenience, and limited accessibility of conventional diagnostic techniques like Polysomnography (PSG). This research presents a novel, data-driven approach for the classification of sleep disorders using machine learning algorithms applied to lifestyle and health-related data. The study explores the performance of individual classifiers, including Support Vector Machines (SVM), Decision Trees, K-Nearest Neighbours (KNN), Random Forests, and Artificial Neural Networks (ANN), and further enhances predictive accuracy through ensemble learning techniques such as Stacking and Voting classifiers. These ensemble models integrate the strengths of multiple base learners, offering improved generalization and reliability. The methodology involves comprehensive preprocessing, feature engineering, and model optimization to handle the nuances of real-world data. Experimental results demonstrate that ensemble methods significantly outperform traditional models in classification accuracy, precision, recall, and F1-score. By leveraging commonly available health metrics instead of clinical-grade sensor data, the proposed system offers a scalable and cost-effective solution for early diagnosis, particularly suited for remote or resource-constrained settings. This work underscores the potential of machine learning in developing accessible, non-invasive diagnostic tools that support public health initiatives and individual patient care. --- #### Assessing Adversarial Vulnerabilities in Fake News Detection: A Comparative Study of GPT-2 and BERT Variants **Authors:** Ishan Bhardwaj, Vaibhav Agrawal, Vaibhav Pratap Singh, Dinesh Kumar Vishwakarma | **Affiliation:** Department of Information Technology, Delhi Technological University, Delhi, India ,Professor, Department of Information Technology, Delhi Technological University, Delhi, India **Pages:** 15-26 | **Published:** 2025/05/30 | **DOI:** https://doi.org/10.5281/zenodo.17523103 **URL:** https://www.ijama.in/papers?paper=Assessing+Adversarial+Vulnerabilities+in+Fake+News+Detection%3A+A+Comparative+Study+of+GPT-2+and+BERT+Variants | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1759768822_May%2025IJAMA2.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17523103, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17523103 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Assessing+Adversarial+Vulnerabilities+in+Fake+News+Detection%3A+A+Comparative+Study+of+GPT-2+and+BERT+Variants | **Publication Year:** 2025 | **Volume/Issue:** Volume 2, Issue 5, May 2025 **Keywords:** Adversarial Attacks, Fake News Detection, BERT, RoBERTa, DistilBERT, GPT-2, TextAttack, Model Robustness, NLP Security **Abstract:** The increasing sophistication of fake news dissemination poses a growing threat to digital information integrity, demanding the deployment of robust and intelligent detection systems. Transformer-based language models particularly BERT, RoBERTa, DistilBERT, and GPT-2have shown promising results in detecting misinformation by leveraging deep contextual understanding. However, their vulnerability to adversarial attacks reveals a critical weakness in their deployment for real-world applications. This study conducts a comprehensive evaluation of these models under both standard and custom adversarial attack scenarios to assess their reliability in detecting manipulated or misleading content. Using the "newsmediabias/fake_news_elections_labelled_data" dataset, we fine-tune each model and subject them to a battery of adversarial techniques, including TextFooler, PWWS, BAE, DeepWordBug, TextBugger, as well as novel attack methods designed specifically for this study: Enhanced Substitution Attack (ESA) and Comprehensive Text Attack (CTA). We analyze model behavior in terms of accuracy degradation, perturbation efficiency, and computational cost. Our findings reveal stark contrasts in model robustness: while RoBERTa maintains the highest performance on clean data, it�along with other models�is significantly compromised under even subtle adversarial manipulations. The study highlights GPT-2's limitations as a generative model repurposed for classification, as it fails catastrophically under most attack conditions. These insights underscore the urgent need for adversarial resilience in fake news detection systems and pave the way for future research focused on integrating robust defense mechanisms into transformer-based architectures --- #### Memes Under the Lens: Multimodal Offensive Content Classification Using Text and Images **Authors:** Jasraj Singh Sehmbey, Kanishk Srivastava, Tejasv Kaushik, Dinesh Kumar Vishwakarma | **Affiliation:** Department of Information Technology, Delhi Technological University, Delhi, India ,Professor, Department of Information Technology, Delhi Technological University, Delhi, India **Pages:** 27-36 | **Published:** 2025/05/30 | **DOI:** https://doi.org/10.5281/zenodo.17523653 **URL:** https://www.ijama.in/papers?paper=Memes+Under+the+Lens%3A+Multimodal+Offensive+Content+Classification+Using+Text+and+Images | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1759768843_May%2025IJAMA3.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17523653, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17523653 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Memes+Under+the+Lens%3A+Multimodal+Offensive+Content+Classification+Using+Text+and+Images | **Publication Year:** 2025 | **Volume/Issue:** Volume 2, Issue 5, May 2025 **Keywords:** Multimodal Classification, Offensive Content Detection, Memes, Deep Learning, Convolutional Neural Networks, Transformer Models, Late Fusion, Content Moderation, Social Media, Hate Speech **Abstract:** Memes, with their fusion of images and text, have become a cornerstone of digital communication, encapsulating humor, cultural critique, and social commentary. However, their potential to disseminate offensive or harmful content presents a formidable challenge for automated content moderation systems, which often struggle to decipher the complex interplay between visual and textual elements. This study proposes an innovative multimodal deep learning framework to identify offensive memes, utilizing a robust dataset of annotated memes designed to test the synergy of text and image modalities. The approach employs the Inception-ResNet-V2 model, an advanced convolutional neural network, to extract intricate visual features from meme images, complemented by a transformer-based model that captures nuanced textual semantics. These modalities are integrated through a late-fusion strategy, enabling the model to interpret combined meanings that elude unimodal systems. Experimental evaluation reveals a balanced performance, achieving an overall accuracy of 55% and a macro-averaged F1-score of 0.51. The framework demonstrates notable strength in detecting non-offensive content, with a recall of 0.83, indicating reliability in identifying benign memes. However, its lower recall of 0.26 for offensive content highlights the difficulty of capturing subtle or context-dependent harmful intent. These findings illuminate the intricacies of multimodal classification and underscore the need for advanced techniques to address semantic ambiguities. By enhancing the detection of offensive content, this research contributes to the development of more effective content moderation tools, fostering safer and more inclusive online environments. It also lays a foundation for future explorations into real-time applications and cross-cultural adaptations, addressing the evolving landscape of digital communication. --- #### An Extensive Analysis of Potassium Dinitramide (KDN): Synthesis, Properties and Applications **Authors:** Himanshu Kshirsagar | **Affiliation:** Aeronautical Department Priyadarshini College of Engineering Nagpur University, India **Pages:** 37-48 | **Published:** 2025/05/30 | **DOI:** https://doi.org/10.5281/zenodo.17523696 **URL:** https://www.ijama.in/papers?paper=An+Extensive+Analysis+of+Potassium++Dinitramide+%28KDN%29%3A+Synthesis%2C+Properties++and+Applications | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1759768861_MAY%2025IJAMA4.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17523696, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17523696 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=An+Extensive+Analysis+of+Potassium++Dinitramide+%28KDN%29%3A+Synthesis%2C+Properties++and+Applications | **Publication Year:** 2025 | **Volume/Issue:** Volume 2, Issue 5, May 2025 **Keywords:** Potassium dinitramide (KDN), Synthesis, Ammonium dinitramide (ADN), Ammonium perchlorate, neutralization, defense technology, energetic materials, nitramine oxidizer, green propellent, thermal stability, oxidizer **Abstract:** This work focuses on the synthesis, properties, and applications of potassium dinitramide (KDN), a critical intermediate in the development of eco-friendly green propellants like ammonium dinitramide (ADN).

Industry 4.0, which involves the integration of cyber-physical systems (CPS), IoT, AI, and Big Data, is largely focused on increasing productivity and operational effectiveness through automation, intelligent factories, and data-driven decision-making. But excessive dependence on automation may restrict flexibility and human responsiveness in manufacturing. To counter this, Industry 5.0 has come into being, advocating human-machine collaboration, sustainability, and flexible manufacturing in favor of a balanced industrial strategy. This research investigates how Industry 5.0 deviates from Industry 4.0 using the case study of Mecgale Pneumatics Pvt. Ltd. The investigation analyzes the effectiveness of IoT-led predictive maintenance, AI-based analysis, wearable smart devices, and collaborative robots for enhancing industrial efficiency. Although production efficiency is increased by Industry 4.0 technologies like auto-CNC cutting and AI-accelerated quality control, Industry 5.0 considers cobot inclusion, worker protection innovation, and eco-friendly production to create an environment that prioritizes humans during production. The results indicate that Industry 4.0 enhances automation, minimizes downtime, and increases total productivity, whereas Industry 5.0 provides greater flexibility, personalization, and worker involvement. While automation minimizes the need for human intervention, it is possibly not ideal for low-volume, flexible, or custom production. Industry 5.0 combines automation and human intelligence, which fosters a sustainable and innovative industrial ecosystem. Therefore, in summary, this research suggests the integration of the efficiency of Industry 4.0 and the human advantage of Industry 5.0. Nevertheless, these challenges as high capital investments, upscaling workers, and integration complexities ought to be overcome through staged adoption to facilitate transitioning to next-generation, sustainable industrial systems smoothly. --- ### Issue 6 — June 2025 — https://www.ijama.in/archives.php?volume=2&issue=6 #### Summation Formulae for a Series Involving the I - Functions of Several Variables **Authors:** P C Sreenivas, T M Vidya, T M Vasudevan Nambisan, P V Maya | **Affiliation:** 1Principal, Gurudev Arts and Science College Mathil, Payyanur, 2Assistant Professor, Department of Mathematics, Mahatma Gandhi College Iritty, Kannur, Kerala, 3Emeritus Professor, College of Engineering Trikaripur, Kasargod, 4Assistant Professor, Department of Mathematics, Mahatma Gandhi College Iritty, Kannur, Kerala **Pages:** 1-7 | **Published:** 2025/06/30 | **DOI:** https://doi.org/10.5281/zenodo.17523826 **URL:** https://www.ijama.in/papers?paper=Summation+Formulae+for+a+Series+Involving+the+I+-+Functions+of+Several+Variables | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1759768560_June%2025IJAMA1.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17523826, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17523826 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Summation+Formulae+for+a+Series+Involving+the+I+-+Functions+of+Several+Variables | **Publication Year:** 2025 | **Volume/Issue:** Volume 2, Issue 6, June 2025 **Keywords:** I - function of several variables, Gamma function, Special functions, Pocchammer symbol **Abstract:** - In this paper, we derive two new summation formulae for a class of series involving I- functions of several variables.

Recent progress in transfer learning, multilingual pretraining, parameter-efficient adaptation, data augmentation, and community-driven dataset creation has substantially improved capabilities for many such languages, yet large performance gaps remain compared to high-resource languages. This article surveys the technical advances that enable NLP for low-resource languages (including unsupervised and weakly supervised methods, multilingual and massively multilingual models, few-shot and in-context learning with large language models, and adapter/LoRA-style parameter-efficient fine-tuning). We examine practical pipelines for tasks such as machine translation, speech recognition, OCR, and information extraction; describe prominent dataset and community projects; summarize typical evaluation strategies and their pitfalls; and outline promising research directions (community data collection, privacy-preserving methods, on-device adaptation, and ethics-aware deployments). The review highlights approaches that balance performance, compute cost, and data-efficiency, and recommends research and deployment practices to accelerate inclusive language technology. --- #### Wide Bandgap Semiconductors for Power Electronics **Authors:** M.

Instead, the development of humankind has consistently been shaped by myths, imagined orders, survival instincts, and the pursuit of power. From the cognitive revolution to the agricultural transition, from the consolidation of empires to the union of capitalism and science, each milestone in history reflects humanity�s capacity to cooperate through shared beliefs while simultaneously creating inequalities and hierarchies. The agricultural revolution, for instance, did not simply secure food surpluses; it also entrenched anxieties, labor exploitation, and rigid social structures. Empires extended control over vast populations through narratives of religion and political legitimacy, while capitalism and scientific progress became powerful engines of expansion, innovation, and domination. Industrialization intensified this trajectory, generating both unprecedented technological progress and alarming ecological destruction, as well as social alienation and the breakdown of traditional bonds. The thread that runs through these transformations is not one of justice, but of continuous adaptation through imagined realities and shifting balances of power. In the present age, humanity faces its most decisive challenge: the pursuit of immortality through biotechnology, artificial intelligence, and genetic engineering. This so-called race for overcoming death risks replacing Homo sapiens with post-human or non-organic beings, raising profound ethical and existential questions. Thus, the history of humanity is not a linear progression toward fairness or equality but a complex and often unsettling narrative of myths, survival strategies, and technological ambitions. The future of our species depends not on illusions of justice or immortality but on how responsibly we navigate the powers we have created --- ### Issue 10 — Oct 2025 — https://www.ijama.in/archives.php?volume=2&issue=10 #### Justice Power and the Myths of Human Progress in Post Human Futures **Authors:** Navneet Kumar Verma | **Affiliation:** Department of Political Science, Government College, Siwana-Balotra, Rajasthan, India **Pages:** 1-9 | **Published:** 2025/11/30 | **DOI:** https://doi.org/10.5281/zenodo.17328543 **URL:** https://www.ijama.in/papers?paper=Justice+Power+and+the+Myths+of+Human+Progress+in+Post+Human+Futures | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1760341138_IJAMA0CT251.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17328543, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17328543 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Justice+Power+and+the+Myths+of+Human+Progress+in+Post+Human+Futures | **Publication Year:** 2025 | **Volume/Issue:** Volume 2, Issue 10, Oct 2025 **Keywords:** Justice, Myths, Cognitive Revolution, Agricultural Revolution, Empires; Capitalism, Science, Industrialization, Immortality, Homo sapiens, Artificial Intelligence, Biotechnology, Future of Humanity **Abstract:** Human civilization has long been narrated as a journey toward justice, equality, and enlightenment. However, a critical examination of history demonstrates that these ideals have often functioned as myths—powerful yet illusory constructs that legitimize hierarchies, stabilize authority, and drive social cooperation. From the cognitive revolution to the agricultural and industrial transformations, humanity’s progress has consistently been intertwined with inequality, domination, and ecological disruption. The scientific revolution and the rise of capitalism further reshaped global structures, embedding justice in the rhetoric of growth and prosperity while marginalizing vast populations. Today, new frontiers in biotechnology, artificial intelligence, and genetic engineering revive ancient myths of immortality and omnipotence, raising profound ethical and existential dilemmas. This paper revisits the trajectory of human history through the lens of justice and imagined orders, tracing continuities between ancient myths and modern technological ambitions. By analyzing revolutions in cognition, agriculture, empire-building, capitalism, and science, the study argues that justice has rarely been realized as a universal principle; instead, it persists as a legitimizing narrative. The future of humankind depends on recognizing these illusions and consciously shaping narratives and technologies to promote survival, sustainability, and ethical responsibility rather than domination --- #### A Structural Analysis of FMRA in L2(R)n **Authors:** Bijumon Ramalayathil, Haseena C, Priyanka P, Jimly Manuel | **Affiliation:** Department of Mathematics , Mahatma Gandhi College, Iritty, Keezhur P.O., Kerala, India. **Pages:** 10-13 | **Published:** 2025/10/30 | **DOI:** https://doi.org/10.5281/zenodo.17338877 **URL:** https://www.ijama.in/papers?paper=A+Structural+Analysis+of+FMRA+in+L2%28R%29n | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1760341407_IJAMA0CT252.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17338877, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17338877 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=A+Structural+Analysis+of+FMRA+in+L2%28R%29n | **Publication Year:** 2025 | **Volume/Issue:** Volume: 2, Issue: 10, Oct 2025 **Keywords:** Frame Multiresolution Analysis (FMRA), superspace frames, dilation and translation invariance.AMS Subject Classification: 42C40, 42C15. **Abstract:** Frame Multiresolution Analysis (FMRA) extends the classical concept of multiresolution analysis to the context of frames in Hilbert spaces. In this paper, we investigate FMRA in the superspace L2(R)n and establish that the frame property of the system {Tkϕ1 ⊕ · · · ⊕ ϕn : k ∈ Z} in V0 is preserved under dilations by the operator UC. Specifically, we prove that the dilated-translated system {Uj Tkϕ1 ⊕ · · · ⊕ ϕn : k ∈ Z} forms a frame for Vj with the same frame bounds as in V0. This result demonstrates the stability of FMRA frames under generalized dilation and translation operators in L2(R)n, facilitating their application to multiple signal processing and superwavelet constructions --- #### A Special Class of Multi-Fuzzy Algebra Over Multi-Fuzzy Field **Authors:** K.

This paper explores the properties and algebraic structures of multi-fuzzy algebras over multi-fuzzy field, generalizing the framework of fuzzy vector spaces and fuzzy fields. We introduce a novel approach using a bridge function h to define multi-fuzzy algebras when the dimensions of the multi-fuzzy set on an algebra A and the multi-fuzzy field differ. The paper investigates the influence of this bridge function on the algebraic properties of these spaces and provides a comprehensive analysis of their structure. Key results include the characterization of multi-fuzzy algebras, their intersections, and their behaviour under linear transformations --- #### Clinical Evaluation of the Vascular Plug System for Arterial and Venous Embolization in Peripheral Vasculature **Authors:** Minocha Dr. Pramod Kumar, Kothwala Dr. Deveshkumar, Shah Khusboo, Machhi Diya, Modi Darshita, Durani Ovesh, Patel Tushar | **Affiliation:** Meril Medical Innovations Private Limited, Bilakhia House, Survey no.879, Muktanand marg, Chala, Vapi, Dist-Valsad, Gujarat, 396191, India. **Pages:** 26-35 | **Published:** 2025/10/30 | **DOI:** https://doi.org/10.5281/zenodo.17527920 **URL:** https://www.ijama.in/papers?paper=Clinical+Evaluation+of+the+Vascular+Plug+System+for+Arterial+and+Venous+Embolization+in+Peripheral+Vasculature | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1762309412_IJAMAOCT254.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17527920, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17527920 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Clinical+Evaluation+of+the+Vascular+Plug+System+for+Arterial+and+Venous+Embolization+in+Peripheral+Vasculature | **Publication Year:** 2025 | **Volume/Issue:** Volume 2, Issue 10, Oct 2025 **Keywords:** Vascular plug, Embolization, Portal hypertension with gastric and oesophageal varices, Antiphospholipid syndrome, Artreiovenous fistula. **Abstract:** Arterial and venous embolization in peripheral vasculature with vascular plug is a well-established procedure for adults and elderly. The aim of this clinical evaluation is to assess the vascular plug safety and efficacy in treating in peripheral vascular conditions like control bleeding, treat aneurysms and target tumors, traumatic injuries, Arteriovenous malformation, venous malformations, deep vein thrombosis and varicose veins. An analysis of the four cases, in first case patient was diagnosed with portal hypertension with gastric and oesophageal varices. In the second case patient involved with an antiphospholipid syndrome that developed a superficial femoral artery aneurysm. While third and fourth case both patients were diagnosed with Artreiovenous fistula. Medical records follow up imaging and post procedure monitoring were used to evaluate a clinical result. The vascular plug successfully manages this clinical condition in all cases, with minimal complications. No recurrence of vascular plug was observed in all patients. The vascular plug is a safe and effective device for the embolization of arteries and veins. In comparison, traditional methods like medication and coils treatment offers more effective, low complication, less invasive with excellent long term outcome. These results provide acceptance of the vascular plug use as preferred treatment for arterial and venous embolization in peripheral vasculature with potential to improve clinical outcomes and reduce recovery time --- ### Issue 11 — Nov 2025 — https://www.ijama.in/archives.php?volume=2&issue=11 #### The Techno Human Paradox: A Theoretical Framework **Authors:** Navneet Kumar Verma | **Affiliation:** Department of Political Science, Government College, Siwana, Balotra, Rajasthan, India , drnavneetverma@gmail.com **Pages:** 1-12 | **Published:** 2025/11/30 | **DOI:** https://doi.org/10.5281/zenodo.17528033 **URL:** https://www.ijama.in/papers?paper=The+Techno+Human+Paradox%3A+A+Theoretical+Framework | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1762310807_IJAMANOV251.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17528033, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17528033 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=The+Techno+Human+Paradox%3A+A+Theoretical+Framework | **Publication Year:** 2025 | **Volume/Issue:** Volume 2 , Issue 11, November 2025 **Keywords:** Human Autonomy, Digital Age, Technological Influence, Information Overload, Cognitive Development, Digital Dependency, Ethical Technology, Techno-Human Coexistence **Abstract:** The rapid acceleration of technological advancements has transformed human life, social structures, knowledge systems, and modes of interaction, creating a techno-human paradox wherein technology designed to empower humanity increasingly challenges human autonomy and identity. This paper presents a conceptual analysis of emerging global challenges arising from digital dependency, information saturation, declining critical thinking, and weakened human-to-human connect in the digital age. While technology has enhanced access to information, communication, and efficiency, its unintended consequences such as digital manipulation, loss of individual reasoning, dependency on algorithm-driven decisions, and erosion of experiential learning have raised concerns about the future of human cognitive and social evolution. This research highlights the widening gap between technological progress and human emotional, ethical, and conscious development, emphasising the risk of technology overpowering human judgement. The study identifies the urgent need for strengthening human values, reflective thinking, self-awareness, and responsible digital engagement to retain human distinctiveness in a rapidly automated world. Adopting a qualitative conceptual approach, this paper synthesises scholarly perspectives to formulate a theoretical framework for preserving human relevance amidst growing technological dominance.

Untreated greywater poses serious risks to the public while also causing damage to the environment. Traditional solar stills face limitations of low yields when treating water. This research focuses on the design and evaluation of an acrylic solar still, incorporating a third-order Fresnel lens to concentrate solar energy and enhance the evaporation rate. IoT-based monitoring systems using a DHT11 sensor and Arduino Nano enabled real-time assessment of temp and relative humidity, monitoring the system’s performance. Domestic kitchen and handwashing greywater was processed, achieving a calculated concentration ratio of roughly 700x and focal irradiance of approximately 350,000 W/m². 1.5 L/h was achieved during testing, resulting in a calculated yield of 31.25 L/m²/day, more than five times the output of passive stills. The water produced was distilled to the point of being visually and odorlessly free of impurities. The developed system is easily scalable and affordable, providing an effective solution to greywater treatment for off-grid and low-resource communities. --- #### Investigating Wave Energy Effects on Swimmer Dynamics: An Analytical and Experimental Approach **Authors:** Mrinank Bhattacharjee, Hitendra Vaishnav | **Affiliation:** Singapore International School, Mumbai, India **Pages:** 10-18 | **Published:** 2025/12/30 | **DOI:** https://doi.org/10.5281/zenodo.17941394 **URL:** https://www.ijama.in/papers?paper=Investigating+Wave+Energy+Effects+on+Swimmer+Dynamics%3A+An+Analytical+and+Experimental+Approach | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1765797608_IJAMADEC25V2A1202.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17941394, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17941394, https://www.academia.edu/145524910/Investigating_Wave_Energy_Effects_on_Swimmer_Dynamics_An_Analytical_and_Experimental_Approach **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Investigating+Wave+Energy+Effects+on+Swimmer+Dynamics%3A+An+Analytical+and+Experimental+Approach | **Publication Year:** 2025 | **Volume/Issue:** Volume 2 Issue 12 ,Dec-2025 **Keywords:** Wave energy Parameters, Flap Mechanism, Swimmer Motion pattern, Motion analysis, Fast Fourier Transform (FFT), Power Spectral Density (PSD). **Abstract:** Swimming in open water has unique biomechanical challenges due to the effects of various waves and environmental factors on the swimmer’s pattern, stability, and performance. This study examined how wave energy parameters affected a swimmer’s biomechanical response in a water environment. In this study, a theoretical and experimental approach investigated wave energy through parameters such as amplitude, frequency, and power using standard fluid dynamic equations. A wave generation system utilizing two MG996R motors was de- signed to control a flap mechanism, which simulates wave motion. The system is controlled via a microcontroller to create waves, and a swimmer model fitted with an MPU6050 triaxial accelerometer and gyroscope was used to collect precise motion capture data that was as detailed as possible. Controlled experiments were conducted under multiple wave conditions. Data acquisitions took place and were analyzed in the time and frequency domains. Data was analyzed in the frequency domain using Fast Fourier Transform (FFT) to determine dominant frequency components in the swimmer’s movements. Power Spectral Density (PSD) provided an estimate of the energy distribution in the swimmer’s movements. The results showed that as the wave energy increased, the swimmer’s body displacements increased, the swimmer’s in- stability increased, and the average corrective movement frequency also increased. The results illustrate that environmental wave dynamics had a significant effect on swimmer biomechanics and provide implications for training opportunities for open water swimmers, safety for athletes, and human-aquatic body interactions --- #### Detecting Illegal Water Extraction Using Hydrophone Technology and Its Financial Implications on Common People **Authors:** Gauri Maheshwari, Amey Chavan | **Affiliation:** Jayshree Periwal International School, Jaipur, India **Pages:** 19-30 | **Published:** 2025/12/30 | **DOI:** https://doi.org/10.5281/zenodo.17941511 **URL:** https://www.ijama.in/papers?paper=Detecting+Illegal+Water+Extraction+Using+Hydrophone+Technology+and+Its+Financial+Implications+on+Common+People | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1765797738_IJAMADEC25V2A1203.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17941511, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17941511, https://www.academia.edu/145525015/Detecting_Illegal_Water_Extraction_Using_Hydrophone_Technology_and_Its_Financial_Implications_on_Common_People **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Detecting+Illegal+Water+Extraction+Using+Hydrophone+Technology+and+Its+Financial+Implications+on+Common+People | **Publication Year:** 2025 | **Volume/Issue:** Volume 2 Issue 12 , Dec-2025 **Keywords:** water extraction, hydrophone, demand and supply curve, policy implementation. **Abstract:** especially in metropolitan and suburban areas of developing countries, where reg- ulatory frameworks are thin, and non-revenue water (NRW) losses incur hefty economic and social burdens. This study show-cases an unmanned, low-cost water monitoring system based on hydrophones that can detect illegal water withdrawals through the capture and classification of underwater sound emissions. The system employs a discrete JFET-based preamplifier with water flow pattern detection and classification signal processing to filter sound patterns and determine whether the activities related to the flow are legal or illegal using pipe dimensions and flow rates. Engagement in a primary community survey revealed strong public perception towards the importance of fair regulation, combined with a notable intention-action gap with regards to reporting violations, which underscores the case for passive, automated detection systems. Controlled experimental trials estimating detection accuracy showed above 90% ac- curacy, classification of violations based on severity allowed for the structure of proportional punitive responses. The 10-node deployment’s financial model indicated a conservative es- timate of rupees 1.21 crore in net benefit, a 15.2× ROI, and a payback period of under one month. These results stemmed from an analysis carried out under base scenario assumptions. The system’s OPEX of rupees 72,000/year is remarkably lower than the operating costs as- sociated with SCADA retrofit systems, making adoption by municipalities more financially feasible. Recommendations focus on essential enforcement and tiered fines, equitable revenue recycling, enforcement through public transparency, and trust building dashboards. The analy- sis demonstrates that combining acoustic detection with certain economic policies dramatically improve NRW loss mitigation, enforcement efficiency, and water conservation while shielding compliant households from financial penalties. --- #### Comparative Study of Internal Structural Geometry and Material Properties on Soft Gripper Performance **Authors:** Aanjnay Maan Singh, Hitendra Vaishnav | **Affiliation:** Jamnabai Narsee International School **Pages:** 31-42 | **Published:** 2025/12/30 | **DOI:** https://doi.org/10.5281/zenodo.17941570 **URL:** https://www.ijama.in/papers?paper=Comparative+Study+of+Internal+Structural+Geometry+and+Material+Properties+on+Soft+Gripper+Performance | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1765797895_IJAMADEC25V2A1204.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17941570, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17941570, https://www.academia.edu/145525042/Comparative_Study_of_Internal_Structural_Geometry_and_Material_Properties_on_Soft_Gripper_Performance **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Comparative+Study+of+Internal+Structural+Geometry+and+Material+Properties+on+Soft+Gripper+Performance | **Publication Year:** 2025 | **Volume/Issue:** Volume 2 Issue 12 , Dec-2025 **Keywords:** Soft Gripper **Abstract:** Soft grippers signify an important development in soft robotics, granting the ability to safely, effectively, and efficiently manipulate sensitive, nonlinear, or variable-sized objects across many applications from healthcare, food processing, logistics, and human robot collaboration. The two main aspects of any soft gripper's performance are due to fundamental design properties: internal structural geometry and material properties. Not only have previous studies typically assessed these variables in isolation, but there are also few experimental studies assessing their interplay. We present comparative experiments to evaluate the effects of internal geometrical design structures on the performance of 3D-printed TPU soft grippers a highly elastic and durable thermoplastic elastomer, compatible with typical FDM printing processes. Three distinct internal geometries circular, linear, and zigzag were designed and 3D-printed to assess the effects of geometrical design on performance measures like grip force, deformation, adaptability, slip resistance, and durability. The grippers were integrated with a servo-driven gear-synchronized actuation mechanism and performance testing was conducted using force-sensitive resistors (FSRs) to evaluate gripping interaction forces. Experimental results reveal that the linear geometry achieves the highest grip force and slip resistance, the circular geometry provides the greatest adaptability and deformation range, and the zigzag geometry offers a balanced compromise between strength and flexibility with superior long-term durability. These findings highlight the trade-offs between stiffness and compliance inherent in internal geometrical design and emphasize the necessity of jointly considering material properties and geometry when developing application-specific soft grippers. --- #### Design and Evaluation of Spirulina Algae Biofilter Using Exhaust Fan for Industrial Flue Gas Mitigation and Biomass Generation **Authors:** Amyra Pasricha, Hitendra Vaishnav | **Affiliation:** 1Vasant Valley School **Pages:** 43-56 | **Published:** 2025/12/30 | **DOI:** https://doi.org/10.5281/zenodo.17941755 **URL:** https://www.ijama.in/papers?paper=Design+and+Evaluation+of+Spirulina+Algae+Biofilter+Using+Exhaust+Fan+for+Industrial+Flue+Gas+Mitigation+and+Biomass+Generation | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1765798101_IJAMADEC25V2A1205.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17941755, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17941755, https://www.academia.edu/145525293/Design_and_Evaluation_of_Spirulina_Algae_Biofilter_Using_Exhaust_Fan_for_Industrial_Flue_Gas_Mitigation_and_Biomass_Generation **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Design+and+Evaluation+of+Spirulina+Algae+Biofilter+Using+Exhaust+Fan+for+Industrial+Flue+Gas+Mitigation+and+Biomass+Generation | **Publication Year:** 2025 | **Volume/Issue:** Volume 2 Issue 12, Dec-2025 **Keywords:** Spirulina, Biofilter, Biomass Production, Carbon Dioxide Absorption, Industrial Emissions Mitigation **Abstract:** This study demonstrates the design and testing of a biofilter system that uses Spirulina algae to dissipate flue gas emissions from industry while producing biomass. In following the urgent call for affordable carbon capture technology, this study approaches Spirulina, an algae that has an economic and environmental appeal because of its high rates of photosynthesis, rapid growth, and its tolerance to extreme conditions, including industrial carbon dioxide (CO₂) levels. The system uses an exhaust fan to cycle flue gas into the biofilter, a bubbling system to maximize gas-liquid interaction, and a series of real-time monitoring using a temperature gauge, pH meter, and CO₂ indicating bellow to maintain optimal algal growth and photosynthetic conditions. Experimental results confirmed the lethality of Spirulina algae demonstrated by the attenuation of CO₂ concentrations from inlet to outlet of the biofilter. The algal culture also showed a steady increase in biomass, demonstrating a transfer from inorganic carbon to organic substance. Spirulina demonstrated CO₂ absorption rates of 11-13%, which was under optimum conditions, and showed a high tolerance to CO₂ levels usually present in industrial emissions. This biomass is an additional economic benefit with different applications such as biofuels, food, fertilizers, and drugs. The study concludes that Spirulina is a promising organism for carbon capture and biomass production in a controlled setup. The compact, sensor-integrated biofilter system effectively simulates industrial conditions conducive to algal growth, suggesting that microalgae-based systems could play a critical role in climate change mitigation. While the current research was conducted in a laboratory environment, future efforts will focus on scaling the system for real-world industrial applications and evaluating its long-term efficiency and economic viability. --- #### Development and evaluation of an air filtration system combining Electrostatic Precipitators for airborne microplastics **Authors:** Siddharth Ojha, Amey Chavan | **Affiliation:** Delhi Public School Bangalore East, Bangalore, India **Pages:** 57-66 | **Published:** 2025/12/30 | **DOI:** https://doi.org/10.5281/zenodo.17941837 **URL:** https://www.ijama.in/papers?paper=Development+and+evaluation+of+an+air+filtration+system+combining+Electrostatic+Precipitators+for+airborne+microplastics | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1765798331_IJAMADEC25V2A1206.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.17941837, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.17941837, https://www.academia.edu/145525363/Development_and_evaluation_of_an_air_filtration_system_combining_Electrostatic_Precipitators_for_airborne_microplastics **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Development+and+evaluation+of+an+air+filtration+system+combining+Electrostatic+Precipitators+for+airborne+microplastics | **Publication Year:** 2025 | **Volume/Issue:** Volume 2 Issue 12 , Dec-2025 **Keywords:** Electrostatic Precipitator (ESP), Dust Collection System, Particulate Matter (PM) Removal, Indoor Air Purification, Electrostatic Dust Trapping, Particle Charging and Collection, Airborne Particulate Filtration, Electrostatic Field Separation. **Abstract:** Micro plastic particles released into the air as waste pose a significant threat to human beings for a variety of different reasons. Microplastics disperse silently throughout industrial and urban areas, infiltrating the respiratory system and directly serving as a means of spreading toxic waste. In regard to airborne microplastics, research states that those microplastics can be captured through a non-contact process using energy-efficient corona ionization through a novel filtration approach. The microplastics filtration system employs a Van de Graaf genera- tor which generates 200–220 V, allowing for corona ionization of air to a charged mesh screen, leading to collection of particles on a diamond-cut and curved copper collector with ideal field exposure and laminar flow retention. The cylindrical design is reinforced using SolidWorks and CFD, maintaining low pressure drop and high throughput. PLA and PETE tests confirmed the theoretical model’s effectiveness, showcasing a microplastic capture efficiency above 85%. It requires no tools and maintenance, shape-preserving collection morphology, and a modular form factor, which allow it to be integrated into industrial exhausts, indoor environments, and even urban air grids. In contrast to expensive membrane technologies or low-life HEPA filters, this solution is field-deployable, cost-effective, and scalable, targeting one of the most elusive and biologically active pollutants of the modern era. This work expands the use of electrostatic filtration beyond micro-level technologies to a systems-level approach for intervention to pre- serve breathable air at its source. It is not only a machine but a protective shield that redefines clean air in an era of pervasive microplastic pollution. --- #### Deep Learning-Based Predictive Maintenance Framework Using CNN-LSTM Architecture for Industrial Rotating Machinery Fault Detection **Authors:** Dr. K.

Conventional time-based preventive maintenance schedules mitigate catastrophic failure risk but are operationally inefficient, frequently replacing components before their functional end-of-life and incurring unnecessary maintenance expenditure. Condition-Based Monitoring (CBM) through vibration, acoustic, and thermal sensor data offers a route to maintenance scheduling that is both reactive to actual machine health and predictive of imminent failure. The present study proposes and validates a hybrid Convolutional Neural Network–Long Short-Term Memory (CNN-LSTM) architecture for multi-class fault detection in industrial rotating machinery — specifically centrifugal pumps, induction motors, and gearboxes — using time-series sensor data collected over 18 months at a precision engineering facility in Haryana, India. The CNN sub-network extracts spatial features from short-time Fourier transform (STFT) spectrograms of vibration signals, while the LSTM sub-network models temporal dependencies in multi-channel sensor streams including temperature, current draw, and acoustic emission. The proposed CNN-LSTM model achieves 95.6% classification accuracy, 94.8% precision, and an AUC of 0.981 across five fault classes (normal, bearing fault, shaft misalignment, cavitation, and lubrication deficiency) on a held-out test set of 4,400 labelled samples — outperforming standalone Support Vector Machine (87.3%), Random Forest (91.2%), and LSTM (93.8%) baselines. Real-time deployment on an NVIDIA Jetson AGX Xavier edge inference platform achieves end-to-end latency of 23 ms, suitable for safety-critical online monitoring applications. The framework reduces false positive maintenance alerts by 38% relative to threshold-based alarm systems and projects a 27% reduction in annual maintenance cost over a three-year evaluation horizon. --- ## Volume 3 (2026) ### Issue 1 — Jan 2026 — https://www.ijama.in/archives.php?volume=3&issue=1 #### Application of Artificial Intelligence in Climate Change Prediction and Environmental Sustainability **Authors:** Rahul Dev Sharma, Meenakshi Rawat, Saurabh Mishra, Priyanka Joshi | **Affiliation:** Department of Multidisciplinary Studies, Himalayan Institute of Science & Technology, Dehradun, India **Pages:** 1-5 | **Published:** 2026/01/30 | **DOI:** 10.5281/zenodo.18182425 **URL:** https://www.ijama.in/papers?paper=Application+of+Artificial+Intelligence+in+Climate+Change+Prediction+and+Environmental+Sustainability | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1767854480_IJAMAJAN26V3A0101.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.18182425, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.18182425, https://www.academia.edu/145847082/Application_of_Artificial_Intelligence_in_Climate_Change_Prediction_and_Environmental_Sustainability **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Application+of+Artificial+Intelligence+in+Climate+Change+Prediction+and+Environmental+Sustainability | **Publication Year:** 2026 | **Volume/Issue:** Volume 3 Issue 1 , Jan-2026 **Keywords:** Artificial Intelligence, Climate Change, Environmental Sustainability, Machine Learning, Climate Modeling **Abstract:** Climate change presents a critical global challenge requiring accurate forecasting and effective mitigation strategies.

This research utilizes the principles of Behavioral Economics to investigate the cognitive biases that drive this discrepancy. By conducting a controlled experiment with 2,500 digital consumers, the study evaluates how "Choice Architecture"—specifically default settings, framing effects, and hyperbolic discounting—influences data disclosure behavior. Our findings suggest that consumers are 40% more likely to share sensitive data when the benefits are immediate and the privacy risks are framed as distant or abstract. The paper identifies the role of "Dark Patterns" in manipulative interface design and proposes a framework for "Ethical Nudging." This research offers strategic insights for MBA practitioners and policymakers to design transparent digital ecosystems that balance corporate data needs with genuine consumer autonomy. --- #### Biophilic Urbanism and the Psychological Impact of Green Spaces on Urban Social Cohesion **Authors:** Siddharth Mukherjee, Kavya Sundaram, Ishwar Dayal, Zoya Qureshi | **Affiliation:** Faculty of Social Sciences, Banaras Hindu University Department of Sociology, Jamia Millia Islamia, New Delhi **Pages:** 37-41 | **Published:** 2022/02/24 | **DOI:** https://doi.org/10.5281/zenodo.18780070 **URL:** https://www.ijama.in/papers?paper=Biophilic+Urbanism+and+the+Psychological+Impact+of+Green+Spaces+on+Urban+Social+Cohesion | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1771999172_IJAMAFEB26V3A0210.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.18780070, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.18780070 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Biophilic+Urbanism+and+the+Psychological+Impact+of+Green+Spaces+on+Urban+Social+Cohesion | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 2, Feb 2026 **Keywords:** Environmental Psychology, Biophilic Urbanism, Social Cohesion, Urban Density, Mental Health, Green Infrastructure, Social Capital, Restorative Environments, Attention Restoration Theory, Urban Stress Syndrome, Public Health, Sensory Overload, Community Resilience, Biophilic Design, Nature Deficit Disorder **Abstract:** As global populations increasingly concentrate in hyper-urbanized environments, the psychological disconnect from natural landscapes has become a significant public health concern. This research explores the concept of Biophilic Urbanism—the strategic integration of natural elements into city planning—and its specific impact on community mental health and social cohesion. By conducting a comparative analysis of three distinct residential districts, the study evaluates how access to "High-Quality Green Spaces" (HQGS) influences stress levels, perceived loneliness, and neighborly trust. Our findings, based on physiological markers (cortisol levels) and psychometric surveys from 1,200 residents, indicate that proximity to integrated natural environments reduces chronic stress by 25% and significantly increases "Social Capital" scores. The paper argues that green infrastructure is not merely an aesthetic choice but a fundamental psychological necessity. We propose a "Psychologically Informed Urban Design" framework to mitigate the negative mental health outcomes of urban density in the late 2020s. --- #### Sustainable Energy And Social Engagement: An Analytical Study on Evaluating Surya Ghar Implementation in Rural Coimbatore **Authors:** Dr. M.S.

The study underscores the importance of integrating social engagement strategies with policy frameworks to ensure equitable and sustainable energy transitions in rural communities. --- #### Restorative Urbanism and the Social Dynamics of Biophilic Design in Aging Urban Centers **Authors:** Elena Rodriguez, Simon Vance, Aris Theron, Naomi Oka | **Affiliation:** Department of Environmental Planning, University of Groningen, Netherlands **Pages:** 49-53 | **Published:** 2026/02/27 | **DOI:** https://doi.org/10.5281/zenodo.18816179 **URL:** https://www.ijama.in/papers?paper=Restorative+Urbanism+and+the+Social+Dynamics+of+Biophilic+Design+in+Aging+Urban+Centers | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1772201230_IJAMAFEB26V3A0212.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.18816179, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.18816179 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Restorative+Urbanism+and+the+Social+Dynamics+of+Biophilic+Design+in+Aging+Urban+Centers | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 2, Feb 2026 **Keywords:** Biophilic Urbanism, Urban Planning, Social Cohesion, Gerontology, Green Infrastructure, Sustainable Cities, Nature-Based Solutions, Urban Sociology **Abstract:** As global urbanization reaches unprecedented density in 2026, the structural disconnect between residents and natural systems has created "socially sterile" environments. Biophilic Urbanism—the integration of intentional natural systems into the built fabric—offers a framework for social restoration. This paper investigates the impact of "Living Infrastructure" and "Pocket Forests" on the social cohesion and mobility of elderly residents in high-density metropolitan zones. Through a multi-site ethnographic study and spatial mapping across four distinct climates, we analyze how nature-integrated design facilitates intergenerational interaction and reduces social isolation. Our findings indicate that biophilic "Green Plazas" increase the duration of outdoor social activities by 35% among residents over the age of 65. The study concludes that biophilic design is a vital tool for urban resilience, transforming passive transit zones into active, socially restorative communal spaces. --- #### Digital Archaeology and the Algorithmic Reconstruction of Extinct Linguistic Heritage **Authors:** Marcus Thorne, Laila Al-Farsi, Chen Wei | **Affiliation:** Faculty of Humanities, Sultan Qaboos University, Oman **Pages:** 54-57 | **Published:** 2026/02/27 | **DOI:** https://doi.org/10.5281/zenodo.18816212 **URL:** https://www.ijama.in/papers?paper=Digital+Archaeology+and+the+Algorithmic+Reconstruction+of+Extinct+Linguistic+Heritage | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1772201359_IJAMAFEB26V3A0213.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.18816212, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.18816212 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Digital+Archaeology+and+the+Algorithmic+Reconstruction+of+Extinct+Linguistic+Heritage | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 2, Feb 2026 **Keywords:** Digital Archaeology, Linguistic Preservation, Neural Decipherment, Extinct Languages, Cultural Heritage, Computational Linguistics, Epigraphy, Phonetic Reconstruction **Abstract:** The rapid disappearance of global linguistic diversity has prompted an urgent shift toward Digital Archaeology—a field utilizing computational power to preserve and resurrect extinct languages. This paper details the application of Transformer-based Neural Decipherment and Acoustic Phonetic Reconstruction to recover lost dialects from the 1st millennium BCE. By processing fragmented epigraphic data and cross-referencing cognate patterns in surviving daughter languages, we demonstrate the successful reconstruction of a "proto-dialect" previously undocumented in the Southern Arabian Peninsula. Our findings suggest that AI can fill "lexical gaps" in damaged inscriptions with an accuracy rate of 89%. This study highlights the role of digital twins in archiving the intangible heritage of humanity, ensuring that lost languages remain accessible for future historical and cognitive research. --- #### Psychometric Evaluation of Climate Anxiety and Its Correlation with Pro-Environmental Behavioral Paralysis in Gen Z Cohorts **Authors:** R.

This study investigates the prevalence of "Climate Anxiety" among Gen Z individuals (aged 18–26) and its paradoxical effect on pro-environmental behavior (PEB). While moderate anxiety is often a catalyst for action, extreme eco-anxiety can lead to "Behavioral Paralysis" or ecoparalysis—a state of overwhelmed inaction. We utilized the Climate Change Anxiety Scale (CCAS) to survey 4,500 participants across diverse geographical regions. Our results indicate a significant positive correlation between high scores in "Cognitive-Emotional Impairment" and a decrease in self-reported sustainable actions. Furthermore, we identified that "Media Exposure" acts as a primary moderator, where constant consumption of climate-catastrophe narratives exacerbates feelings of helplessness. The paper concludes with a proposed clinical framework for "Climate-Aware Therapy," emphasizing the transition from paralyzing fear to "Constructive Hope" and collective agency. These findings are critical for psychologists, educators, and policymakers seeking to support youth mental health in a warming world.. --- ### Issue 3 — March 2026 — https://www.ijama.in/archives.php?volume=3&issue=3 #### The Silver Economy and Geriatric Consumer Behavior in Urban India **Authors:** Ananya Mukhopadhyay, Karthik Swaminathan, Meherosh Firoz | **Affiliation:** Department of Sociology, Delhi School of Economics, New Delhi **Pages:** 1-6 | **Published:** 2026/03/01 | **DOI:** https://doi.org/10.5281/zenodo.19337065 **URL:** https://www.ijama.in/papers?paper=The+Silver+Economy+and+Geriatric+Consumer+Behavior+in+Urban+India | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1772352693_IJAMAMAR26V3A0301.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19337065, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19337065 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=The+Silver+Economy+and+Geriatric+Consumer+Behavior+in+Urban+India | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 2, March 2026 **Keywords:** Silver Economy, Geriatric Marketing, Demographic Dividend, Urban Longevity, Digital Literacy, Healthcare Consumerism, Multi-generational Housing, Financial Inclusion, Post-retirement Lifestyle, Loneliness Mitigation. **Abstract:** The demographic narrative of India has begun a significant shift as the percentage of the population aged sixty and above reaches a historic high in urban centers. This segment, often termed the Silver Economy, represents a diverse and increasingly affluent consumer base with distinct psychological and physiological needs. This paper investigates the evolving patterns of geriatric consumer behavior among the middle and upper-middle classes in Tier-1 Indian cities. Our research examines the intersection of digital adoption, healthcare spending, and the transition from traditional savings-oriented mindsets to lifestyle-oriented consumption. Through a comprehensive survey of 2,500 senior citizens across five metropolitan areas, we analyze how post-retirement aspirations are redefining sectors such as leisure travel, wellness real estate, and assisted technology. The results indicate a substantial increase in discretionary spending within this cohort, driven by higher financial independence and a desire for social connectivity. This study provides a socio-economic framework for businesses to pivot toward inclusive marketing strategies, ensuring that the Silver Economy becomes a driver of inclusive growth rather than a demographic challenge. --- #### Sustainable Logistics and Green Supply Chain Management in Emerging Markets **Authors:** Siddharth R., Meenakshi V., Rohan D. | **Affiliation:** Department of Industrial Engineering, Regional Institute of Technology, Coimbatore, Tamil Nadu **Pages:** 7-13 | **Published:** 2026/03/02 | **DOI:** https://doi.org/10.5281/zenodo.19337143 **URL:** https://www.ijama.in/papers?paper=Sustainable+Logistics+and+Green+Supply++Chain+Management+in+Emerging+Markets | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1772508129_IJAMAMAR26V3A0302.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19337143, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19337143 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Sustainable+Logistics+and+Green+Supply++Chain+Management+in+Emerging+Markets | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** Green Supply Chain Management (GSCM), Sustainable Logistics, Reverse Logistics, Carbon Footprint, Emerging Economies, Circular Economy, Multi-modal Transportation, E-waste Management, Environmental Compliance, Supply Chain Resilience. **Abstract:** The rapid industrialization of emerging markets has led to significant economic growth, yet it has simultaneously accelerated environmental degradation through carbon-intensive logistics operations. This paper examines the strategic implementation of Green Supply Chain Management (GSCM) within high-growth regional economies. We investigate the transition from traditional linear supply chains to circular models that prioritize resource recovery and emissions reduction. The study evaluates the primary drivers for sustainability adoption, including regulatory pressure, international trade requirements, and consumer demand for ethical sourcing. Through a mixed-methods analysis of regional logistics hubs, we identify the technical and financial barriers that hinder the widespread adoption of "Green Freight" initiatives. Our research highlights the critical role of IoT-enabled tracking and multi-modal transport optimization in reducing the environmental impact of last-mile delivery. The findings suggest that while initial capital investment remains a challenge, the long-term operational efficiencies gained through waste reduction and fuel optimization provide a compelling business case for sustainability. This paper provides a management framework for balancing economic competitiveness with environmental stewardship in the evolving landscape of global logistics. --- #### Federated Learning Frameworks for Privacy-Preserving Diagnostic Imaging in Multi-Site Hospital Clusters **Authors:** Priyanka K., Naveen R., Zoya A. | **Affiliation:** Faculty of Data Science, Metropolitan Technical University, Bhopal, Madhya Pradesh **Pages:** 14-19 | **Published:** 2026/03/03 | **DOI:** https://doi.org/10.5281/zenodo.19337205 **URL:** https://www.ijama.in/papers?paper=Federated+Learning+Frameworks+for+Privacy-Preserving+Diagnostic+Imaging+in+Multi-Site+Hospital+Clusters | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1772508326_IJAMAMAR26V3A0303.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19337205, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19337205 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Federated+Learning+Frameworks+for+Privacy-Preserving+Diagnostic+Imaging+in+Multi-Site+Hospital+Clusters | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** Federated Learning, Differential Privacy, Healthcare Interoperability, Diagnostic Imaging, Machine Learning, Data Sovereignty, Hospital Clusters, Oncology Informatics, Edge Computing, Medical Data Security. **Abstract:** The advancement of Deep Learning in medical diagnostics is often hindered by the "Data Silo" problem, where strict privacy regulations prevent the pooling of patient data across different healthcare institutions. This paper proposes a Federated Learning (FL) framework designed to train robust diagnostic models for oncology without moving sensitive patient images from their local hospital servers. We examine a decentralized architecture where only model gradients, rather than raw data, are exchanged with a central orchestrator. To further harden the system against reconstruction attacks, we integrate a Differential Privacy (DP) layer that adds calibrated noise to the local updates. The study evaluates the performance of this framework across a simulated cluster of four regional hospitals using high-resolution MRI datasets. Our results indicate that the federated model achieves a diagnostic accuracy within 2.5% of a centrally trained model while ensuring 100% compliance with data residency requirements. The findings provide a scalable roadmap for multi-institutional clinical research, allowing for the development of high-performance AI tools without compromising patient confidentiality or institutional data sovereignty. --- #### The '15-Minute City' Paradox: Socio-Economic Segregation and the Gentrification of Proximity **Authors:** D.

However, as major metropolises from Paris to Seoul implement these frameworks, a "Proximity Paradox" has emerged. This paper investigates how the 15mC model potentially exacerbates socio-economic segregation by concentrating high-value amenities in already affluent districts, leading to "Green Gentrification." Using a comparative analysis of three "15-Minute" pilot projects in diverse global cities, we examine the correlation between "Walkability Scores" and real estate price surges. Our findings suggest that without aggressive "Inclusionary Zoning" and social housing mandates, the 15-minute model risks becoming an exclusive amenity for the elite, effectively "walling off" lower-income residents into 15-minute "service deserts." We propose a revised "Equity-First" framework for hyper-local urbanism that prioritizes cross-district connectivity and essential service distribution for marginalized populations. --- #### Psychometric Evaluation of Climate Anxiety and Its Correlation with Pro-Environmental Behavioral Paralysis in Gen Z Cohorts **Authors:** R.

Modern agricultural machines happen to work for prolonged periods of time in considerably harsh environments. This puts a higher demand on the automatic control systems and steering control in particular. Long-term machine operation leads to variance of the physical parameters of the working fluid, positive overlap in proportional valve, working temperature and machine components. In this paper we will be discussing about Model Reference Adaptive control (MRAC) which is an approach to solve real world problems related to Adaptive Control. The present research is focused on the design and application of model reference adaptive controller (MRAC) for control of steering angle of a heavy duty agriculture mobile machine through a hydraulic cylinder. The synthesized controller is based on simple integrator model of the steering cylinder and Lyapunov stability theorems. The closed-loop system achieves good performance and the adaptive gain is stabilized around its mean value too. --- #### Machine Learning-Driven Predictive Maintenance in Smart Manufacturing **Authors:** Rajesh Kumar Sharma, Priya Nair, Michael T.

Predictive maintenance (PdM) — the paradigm of continuously monitoring equipment health indicators and generating maintenance interventions only when and where required — offers the prospect of 70–85% reduction in unexpected downtime relative to time-based preventive strategies, while simultaneously extending component service life and optimising technician scheduling. The proliferation of Industrial Internet of Things (IIoT) sensor infrastructure, edge computing platforms, and industrial communication standards has created the technical preconditions for pervasive, low-latency PdM implementation across manufacturing plants of diverse scales and sectors. This paper presents a comprehensive PdM framework integrating a novel hybrid Long Short-Term Memory — Gradient Boosting Machine (LSTM-GBM) architecture with an IoT-Edge-Cloud three-tier system design. The LSTM sub-component captures long-range temporal dependencies in multivariate sensor time series — including vibration, acoustic emission, current draw, temperature, and oil particle count — while the GBM sub-component provides rapid, high-precision fault classification on LSTM-generated feature embeddings. A dataset of 2.4 million sensor readings collected from CNC machining centres, industrial compressors, and conveyor systems across three manufacturing facilities over eighteen months was used for model training and validation. The proposed LSTM-GBM model achieved a fault detection accuracy of 94.7%, F1-score of 0.923, and AUC-ROC of 0.978 on the held-out test set, outperforming six benchmark methods including CNN-LSTM, standalone LSTM, standalone GBM, Random Forest, and SVM. Deployment across the three test facilities over a six-month operational trial demonstrated a 67.3% reduction in unplanned downtime, 31.4% decrease in maintenance costs, and a conservative projected annual saving of USD 2.84 million per facility, establishing a compelling operational and financial case for scaled IIoT-PdM implementation. --- #### ESG Integration and Corporate Financial Performance **Authors:** Deepa Srinivasan, Mohammed Irfan Khan, Lakshmi Priya Venkataraman, Arun Chandrasekhar | **Affiliation:** Department of Commerce & Management, Bharath Institute of Higher Education and Research, Chennai, Tamil Nadu, India, Department of Business Administration, Shadan Institute of Management Excellence, Hyderabad, Telangana, India **Pages:** 48-55 | **Published:** 2026/03/08 | **DOI:** https://doi.org/10.5281/zenodo.18931170 **URL:** https://www.ijama.in/papers?paper=ESG+Integration+and+Corporate+Financial+Performance | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1772950607_IJAMAMAR26V3A0308.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.18931170, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.18931170 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=ESG+Integration+and+Corporate+Financial+Performance | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** ESG integration, corporate financial performance, stakeholder trust, brand reputation, PLS-SEM, emerging economies, panel data, governance quality, ROA, Tobin's Q, mediation analysis, sustainability **Abstract:** The integration of Environmental, Social, and Governance (ESG) criteria into corporate strategy has undergone a fundamental transformation over the past decade, evolving from a peripheral corporate social responsibility exercise to a mainstream investment and strategic management imperative. Institutional investor coalitions representing over USD 121 trillion in assets under management have committed to ESG-integrated investment mandates, regulatory frameworks in Europe, India, and Southeast Asia have introduced mandatory ESG disclosure requirements for listed firms, and empirical evidence on the financial consequences of ESG performance has grown substantially in volume and methodological sophistication. Yet important questions remain unresolved regarding the mechanisms through which ESG performance translates into financial value — whether through direct operational efficiency gains, through the cultivation of trust-based stakeholder relationships, through brand value enhancement, or through risk mitigation — and the boundary conditions that moderate the ESG-CFP relationship. This study examines the relationship between ESG integration and corporate financial performance (CFP) using a panel dataset of 247 listed firms from six emerging economies (India, Brazil, South Africa, Malaysia, Indonesia, and Turkey) over seven years (2016–2023), yielding 1,607 firm-year observations. Employing Partial Least Squares Structural Equation Modelling (PLS-SEM) combined with two-way fixed effects panel regression, the study tests a conceptual framework in which ESG integration affects ROA, ROE, and Tobin's Q through the parallel mediating pathways of stakeholder trust and brand reputation, moderated by institutional governance quality. Results confirm significant direct effects of ESG composite score on ROA (beta=0.187, p<0.01), ROE (beta=0.164, p<0.05), and Tobin's Q (beta=0.231, p<0.001). Stakeholder trust mediates 31.2% and brand reputation mediates 23.1% of the total ESG-CFP relationship. Governance quality significantly moderates ESG's effect on Tobin's Q, with high-governance-quality firms gaining 34% greater market value premium per unit ESG improvement than low-governance-quality counterparts. --- #### IoT-Enabled Precision Irrigation Management Using Soil Moisture Sensor Networks and Machine Learning-Based Evapotranspiration Prediction **Authors:** Padma Reddy Narayanappa, Suryanarayana Rao Kondapalli | **Affiliation:** ¹Department of Agricultural Engineering, College of Agriculture, Rajendranagar, Hyderabad, Telangana, India ²Department of Agronomy, Sri Konda Laxman Telangana State Horticultural University, Rajendranagar, Hyderabad, Telangana, India **Pages:** 56-59 | **Published:** 2026/02/08 | **DOI:** https://doi.org/10.5281/zenodo.18931200 **URL:** https://www.ijama.in/papers?paper=IoT-Enabled+Precision+Irrigation+Management+Using+Soil+Moisture+Sensor+Networks+and+Machine+Learning-Based+Evapotranspiration+Prediction | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1773063674_IJAMAMAR26V3A0309.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.18931200, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.18931200 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=IoT-Enabled+Precision+Irrigation+Management+Using+Soil+Moisture+Sensor+Networks+and+Machine+Learning-Based+Evapotranspiration+Prediction | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** precision irrigation, IoT sensors, soil moisture monitoring, machine learning, evapotranspiration prediction, random forest, LoRaWAN, rice cultivation, water use efficiency, semi-arid agriculture, India, Telangana, smart farming, fuzzy logic **Abstract:** Irrigated agriculture accounts for approximately 70% of global freshwater withdrawals, yet irrigation water use efficiency in traditional flood irrigation seldom exceeds 40–50%. The convergence of IoT sensor technology, wireless communication, cloud computing, and machine learning presents a transformative opportunity to improve agricultural water use efficiency through real-time precision irrigation management. This study presents the design, implementation, and two-season field validation of an IoT-enabled precision irrigation management system (IoT-PIMS) for rain-fed rice cultivation in semi-arid agro-climatic zones of Telangana, India. The system integrates a wireless sensor network of 144 soil moisture sensors, automated weather stations, LoRaWAN communication, and a cloud-hosted Random Forest ET₀ prediction model trained on 12 years of IMD weather data, with a fuzzy logic irrigation decision engine delivering recommendations via SMS and Android app. Two-season field trials (Kharif 2023 and Rabi 2023–24) across three sites demonstrated: 31.4% water use reduction relative to conventional flood irrigation; paddy yield improvement from 5.21 to 5.84 t/ha; water use efficiency improvement from 0.41 to 0.67 kg grain/m³ (+63.4%); ET₀ prediction RMSE of 0.31 mm/day (NSE=0.89); and system uptime of 97.4%. Farmer perception surveys indicate 84.6% willingness to continue using IoT-PIMS. --- #### Effectiveness of Music Therapy as Adjunct to Standard Pharmacological Analgesia on Post-Operative Pain Intensity, Anxiety, and Analgesic Consumption Among Patients Following **Authors:** Jyoti Ramesh Agarwal, Sabiha Firdaus Shaikh | **Affiliation:** Department of Community Health Nursing, Nootan College of Nursing, Visnagar, Gujarat, India **Pages:** 60-64 | **Published:** 2026/03/09 | **DOI:** https://doi.org/10.5281/zenodo.18931220 **URL:** https://www.ijama.in/papers?paper=Effectiveness+of+Music+Therapy+as+Adjunct+to+Standard+Pharmacological+Analgesia+on+Post-Operative+Pain+Intensity%2C+Anxiety%2C+and+Analgesic+Consumption+Among+Patients+Following | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1773063856_IJAMAMAR26V3A0310.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.18931220, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.18931220 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Effectiveness+of+Music+Therapy+as+Adjunct+to+Standard+Pharmacological+Analgesia+on+Post-Operative+Pain+Intensity%2C+Anxiety%2C+and+Analgesic+Consumption+Among+Patients+Following | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** music therapy, post-operative pain, analgesic consumption, randomised controlled trial, anxiety, hospital stay, non-pharmacological pain management, NRS, BPI, STAI, abdominal surgery, nursing intervention, WHO analgesic ladder **Abstract:** Post-operative pain management represents one of the most fundamental responsibilities of perioperative nursing practice. Inadequately controlled post-operative pain increases risk of pulmonary complications, deep vein thrombosis, impaired wound healing, prolonged hospital stay, and development of chronic pain syndromes, while excessive reliance on opioid analgesia carries risks of respiratory depression, nausea, sedation, and opioid use disorder. Music therapy — a non-pharmacological intervention involving the purposeful use of music to achieve therapeutic goals — has demonstrated efficacy in reducing pain perception across diverse clinical contexts through neuromodulatory mechanisms involving the endogenous opioid system, attentional distraction, and autonomic nervous system modulation. This randomised controlled trial (RCT) evaluated the effectiveness of patient-chosen music therapy as an adjunct to standard WHO analgesic ladder pharmacotherapy on post-operative pain intensity, anxiety, analgesic consumption, and length of hospital stay among 284 adult patients following elective abdominal surgery in three secondary care hospitals in Karnataka. Patients were randomised 1:1 to receive music therapy (30-minute sessions of patient-selected music, three times daily, on post-operative days 1–3) plus standard analgesia, or standard analgesia alone. Pain was assessed using the Numeric Rating Scale (NRS) and Brief Pain Inventory (BPI) at 4, 8, 24, 48, and 72 hours post-operatively. The music therapy group demonstrated significantly lower NRS pain scores at all time-points (p<0.001), 37.3% reduction in tramadol consumption, 33.3% reduction in paracetamol doses, 52.9% reduction in rescue morphine usage, and 0.8-day shorter hospital stay (3.8 vs. 4.6 days, p=0.008). --- #### Deep Learning-Based Automated Grading of Diabetic Retinopathy Using EfficientNet-B4 with Attention Mechanisms and Ensemble Fusion **Authors:** Mohammed Asif Khan | **Affiliation:** Department of Information Technology, Al-Falah University, Faridabad, Haryana, India **Pages:** 65-68 | **Published:** 2026/03/09 | **DOI:** https://doi.org/10.5281/zenodo.18931236 **URL:** https://www.ijama.in/papers?paper=Deep+Learning-Based+Automated+Grading+of+Diabetic+Retinopathy+Using+EfficientNet-B4+with+Attention+Mechanisms+and+Ensemble+Fusion | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1773067151_IJAMAMAR26V3A0311.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.18931236, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.18931236 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Deep+Learning-Based+Automated+Grading+of+Diabetic+Retinopathy+Using+EfficientNet-B4+with+Attention+Mechanisms+and+Ensemble+Fusion | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** diabetic retinopathy, deep learning, EfficientNet-B4, attention mechanism, ensemble learning, fundus image analysis, automated grading, Grad-CAM, focal loss, explainable AI, screening, ophthalmology, India **Abstract:** Diabetic retinopathy (DR) is the leading cause of preventable blindness among working-age adults worldwide, with India alone estimated to have over 11.9 million individuals with vision-threatening DR as of 2023. Early detection through systematic fundus screening can prevent up to 95% of severe vision loss; however, the global shortage of trained ophthalmologists — particularly acute in rural and semi-urban India — creates a critical bottleneck in DR screening programmes. Artificial intelligence-based automated DR grading presents a compelling solution, capable of screening large volumes of fundus images accurately and consistently without specialist involvement. This study develops and evaluates a deep learning ensemble system for automated 5-class DR grading (No DR, Mild, Moderate, Severe, Proliferative DR) using EfficientNet-B4 as the primary backbone with dual attention mechanisms — Squeeze-and-Excitation (SE) networks for channel attention and Convolutional Block Attention Module (CBAM) for spatial attention. The ensemble integrates EfficientNet-B4, ResNet-50, and DenseNet-121 predictions through learned weighted averaging. Training and evaluation employ three publicly available benchmark datasets: APTOS 2019 Blindness Detection, IDRiD, and Messidor-2, comprising 7,842 fundus images. Focal loss (γ=2) and SMOTE oversampling address class imbalance. The proposed ensemble achieves macro-average AUC of 0.983, quadratic-weighted kappa of 0.921, sensitivity of 93.6%, and specificity of 96.8% across five DR grades. Gradient-weighted Class Activation Mapping (Grad-CAM) visualisations confirm that the model correctly attends to clinically relevant pathological features including microaneurysms, haemorrhages, hard exudates, and neovascularisation, providing ophthalmologist-interpretable explainability. --- #### Development, Optimisation, and Biological Evaluation of Herbal Nano-Emulsion Gel Incorporating Centella asiatica, Curcuma longa, and Aloe vera Extracts for Accelerated Wound Healing **Authors:** Preethi Murugesan, Anbuselvan Chandrasekaran, Karthikeyan Rajan | **Affiliation:** Department of Pharmacology, J.K.K.

Traditional Indian medicinal plants — Centella asiatica (gotu kola), Curcuma longa (turmeric), and Aloe vera — possess extensively documented wound healing activities through complementary pharmacological mechanisms: triterpenoids of C. asiatica stimulate collagen synthesis and re-epithelialisation; curcumin from C. longa modulates NF-κB signalling to reduce chronic inflammatory mediator burden; and polysaccharides and acemannan of A. vera accelerate granulation tissue formation and provide moisture retention. This study develops and optimises an oil-in-water herbal nano-emulsion gel incorporating standardised ethanolic extracts of all three plants using Box-Behnken Response Surface Methodology (RSM) to maximise globule size uniformity, zeta potential, drug release rate, and spreadability. The optimised formulation (FO: 15% herbal extract complex, 8% coconut oil, 5% Tween 80, 2% PEG 400, 1.5% Carbopol 940) exhibits mean globule size 187.3 ± 12.4 nm, PDI 0.214, zeta potential −32.7 ± 2.1 mV, and pH 6.4. In vitro drug release across cellulose acetate membrane reaches 91.4% at 24 hours following anomalous (non-Fickian) transport kinetics (n=0.63). In vivo wound closure in a Wistar rat excision model demonstrates 97.6% wound closure by day 14 — significantly superior to framycetin sulfate standard (94.1%), plain herbal gel (88.4%), and untreated control (68.7%). Antimicrobial activity against S. aureus (ZOI 24.3 mm), E. coli (21.8 mm), P. aeruginosa (19.4 mm), and MRSA (22.1 mm) confirms multifunctional wound management efficacy. --- #### PLGA-PEG Nanoparticles Co-encapsulating Curcumin and Docetaxel for Targeted Breast Cancer Therapy **Authors:** Suresh Kumar Periasamy, Nithya Venkatesan **Pages:** 74-76 | **Published:** 2026/03/12 | **DOI:** https://doi.org/10.5281/zenodo.19175084 **URL:** https://www.ijama.in/papers?paper=PLGA-PEG+Nanoparticles+Co-encapsulating+Curcumin+and+Docetaxel+for+Targeted+Breast+Cancer+Therapy | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1773643689_IJAMAMAR26V3A0313.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19175084, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19175084 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=PLGA-PEG+Nanoparticles+Co-encapsulating+Curcumin+and+Docetaxel+for+Targeted+Breast+Cancer+Therapy | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** PLGA-PEG nanoparticles, curcumin, docetaxel, breast cancer, folate receptor targeting, Box-Behnken RSM, encapsulation efficiency, MCF-7, MDA-MB-231, synergism, combination index, nanomedicine, drug delivery **Abstract:** Breast cancer remains the most commonly diagnosed malignancy in women worldwide, accounting for approximately 2.3 million new cases and 685,000 deaths annually. Docetaxel, a potent taxane chemotherapy agent, is severely limited by dose-limiting toxicity and low tumour selectivity. Curcumin exerts complementary anti-cancer activity through NF-kB and STAT3 pathway inhibition but is essentially non-bioavailable orally due to rapid hepatic metabolism. This study synthesises and optimises folate-conjugated PLGA-PEG nanoparticles co-loaded with curcumin and docetaxel using Box-Behnken RSM. The optimised formulation (FO) exhibits particle size 187.4 +/- 9.3 nm, PDI 0.183, zeta potential -28.4 +/- 2.3 mV, curcumin EE 78.4%, and docetaxel EE 82.7%. Sustained biphasic release reaches 93.7% at 72h following Korsmeyer-Peppas anomalous diffusion kinetics. Folic acid functionalisation achieves 3.8-fold enhanced cellular uptake in MCF-7 cells. Cytotoxicity IC50 values of 0.38 ug/mL (MCF-7) and 0.47 ug/mL (MDA-MB-231) are 5.6-fold superior to free drug combination, with combination index (CI) 0.31-0.42 confirming strong synergism. This work establishes folate-targeted PLGA-PEG co-delivery as a scientifically robust nanomedicine strategy for improving the therapeutic index of curcumin-docetaxel combination therapy in breast cancer --- #### Online Learning Fatigue, Academic Engagement, and Dropout Intention Among University Students Under NEP 2020 **Authors:** Saravanan Muthukumar | **Affiliation:** Department of Computer Science Education, Government Arts College, Dharmapuri, India **Pages:** 77-80 | **Published:** 2026/02/14 | **DOI:** https://doi.org/10.5281/zenodo.19151024 **URL:** https://www.ijama.in/papers?paper=Online+Learning+Fatigue%2C+Academic+Engagement%2C+and+Dropout+Intention+Among+University+Students+Under+NEP+2020 | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1773642766_IJAMAMAR26V3A0314.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19144516, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.19144516 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Online+Learning+Fatigue%2C+Academic+Engagement%2C+and+Dropout+Intention+Among+University+Students+Under+NEP+2020 | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** online learning fatigue, NEP 2020, structural equation model, academic engagement, dropout intention, screen overload, social presence, higher education, India, hybrid learning, assessment anxiety, EdTech **Abstract:** The rapid institutionalisation of online and hybrid learning modalities in Indian universities following the COVID-19 pandemic, reinforced by the National Education Policy 2020’s directive to expand digital and online education to at least 50 percent of all higher education enrolments by 2035, has generated a largely unexamined crisis of learner fatigue that threatens to undermine the participation and completion gains that digital education promises. This study investigates the antecedents and consequences of Online Learning Fatigue among undergraduate and postgraduate students across eight Indian universities, proposing a structural model in which screen-time overload, lack of social presence, platform usability deficits, and assessment anxiety jointly drive fatigue, which in turn suppresses academic engagement and elevates dropout intention. Data collected from students over an eighteen-week semester using repeated cross-sectional measurement are analysed through Structural Equation Modelling, and the moderating role of institution type is examined. The findings reveal that fatigue peaks sharply during examination approach periods and that social presence deficit is a more potent driver of fatigue than screen-time overload per se — a finding with direct implications for instructional design in university-level online programmes under NEP 2020 implementation. --- #### Caste, Intergenerational Occupational Mobility, and Income Inequality in Urban South India **Authors:** Govindan Subramanian, Bhavani Krishnaswamy | **Affiliation:** Department of Social Sciences, SNDT Women’s University, Mumbai, Maharashtra, India **Pages:** 81-84 | **Published:** 2026/03/13 | **DOI:** https://doi.org/10.5281/zenodo.19151024 **URL:** https://www.ijama.in/papers?paper=Caste%2C+Intergenerational+Occupational+Mobility%2C+and+Income+Inequality+in+Urban+South+India | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1773642936_IJAMAMAR26V3A0315.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19151024, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19151024 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Caste%2C+Intergenerational+Occupational+Mobility%2C+and+Income+Inequality+in+Urban+South+India | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** caste, social mobility, income inequality, intergenerational mobility, Lorenz curve, Gini coefficient, PLFS, IHDS, OBC, Scheduled Caste, Tamil Nadu, Andhra Pradesh, urban India, occupational transition matrix, reservation policy **Abstract:** The proposition that India’s post-liberalisation economic growth has loosened the bond between caste and economic outcomes — allowing merit, education, and market participation to displace ascribed social identity as the primary determinant of occupational and income trajectory — remains one of the most contested claims in contemporary Indian social science. Proponents of this view point to the visible emergence of successful entrepreneurs, professionals, and corporate executives from Scheduled Caste and Other Backward Class backgrounds as evidence that caste ceilings are yielding to economic mobility. Critics counter that these exemplary cases represent the thin upper tail of a distribution that remains fundamentally shaped by inherited social capital, caste-based network effects in job referral and marriage markets, and the persistent segregation of low-caste communities into low-productivity occupational niches. This paper takes up the debate empirically using two complementary nationally representative datasets: the Periodic Labour Force Survey 2022-23 microdata, which provides detailed household-level employment and income data for the contemporaneous cross-section; and the India Human Development Survey-II (IHDS-II) panel, which links adult children’s occupations to their parents’ occupations and thus permits direct measurement of intergenerational occupational mobility. The combination of cross-sectional inequality measurement through Lorenz curves and Gini decomposition with intergenerational mobility analysis through transition matrices and relative mobility indices provides a more complete picture of the caste-income nexus than either dataset could yield alone. The geographic focus on urban Tamil Nadu and Andhra Pradesh is deliberate. These states have implemented the most comprehensive reservation and targeted development programmes in India — Tamil Nadu’s 69 percent reservation in state educational institutions and government employment is the highest in the country — and constitute natural test cases for the effectiveness of affirmative action in reducing caste-based income inequality and promoting upward mobility over an intergenerational timescale. The urban focus is motivated by the expectation that urban labour markets, with greater economic complexity and reduced social surveillance compared to rural settings, should exhibit the most favourable conditions for caste-independent mobility; findings of persistent caste stratification in this context therefore represent a conservative estimate of caste’s economic effects nationally. This study contributes to a gap in the quantitative sociology of caste in South India by providing state-specific intergenerational transition matrices disaggregated by caste group, a Lorenz-curve-based income inequality decomposition comparing within-caste and between-caste components, and a regression-based decomposition of the earnings gap attributable to observable human capital differences versus residual caste effects. The findings have direct implications for the design of affirmative action policy in the post-EWS reservation era, where the constitutional basis and effectiveness of caste-based reservation is subject to renewed political and judicial scrutiny. --- #### Adoption of Soil Health Cards, Fertiliser Use Efficiency, and Crop Yield Outcomes Among Smallholder Farmers **Authors:** Balasubramanian Venkatesh | **Affiliation:** Department of Agricultural Economics, GKVK Campus, University of Agricultural Sciences, Bengaluru, Karnataka, India **Pages:** 85-88 | **Published:** 2026/03/14 | **DOI:** https://doi.org/10.5281/zenodo.19307173 **URL:** https://www.ijama.in/papers?paper=Adoption+of+Soil+Health+Cards%2C+Fertiliser+Use+Efficiency%2C+and+Crop+Yield+Outcomes+Among+Smallholder+Farmers | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1773643072_IJAMAMAR26V3A0316.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19307173 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Adoption+of+Soil+Health+Cards%2C+Fertiliser+Use+Efficiency%2C+and+Crop+Yield+Outcomes+Among+Smallholder+Farmers | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** Soil Health Card, fertiliser efficiency, smallholder farmers, propensity score matching, crop yield, Tamil Nadu, soil nutrient, nitrogen, phosphorus, potassium, sulphur, zinc, agricultural extension, PM-KISAN, dose-response **Abstract:** The Soil Health Card (SHC) scheme, launched by the Government of India in February 2015 with the objective of providing every farmer in the country with periodic soil nutrient assessments and site-specific fertiliser recommendations, represents the most ambitious soil information programme in India’s agricultural policy history. Despite nationwide issuance of over 22 crore SHCs across three scheme cycles, adoption of the scheme’s fertiliser recommendations by smallholder farmers has been inconsistent, and the relationship between SHC adoption and measurable improvements in soil health indicators, fertiliser use efficiency, and crop yield has been documented only in fragmented, geographically narrow studies that do not account for district-level variation in soil type, cropping system diversity, extension service quality, and farmer literacy levels. This study addresses this gap through a district-level analysis integrating IARI soil testing database records with a structured farm household survey of smallholder farmers across ten districts of Tamil Nadu, comparing soil nutrient status, fertiliser application patterns, and crop yield outcomes between SHC adopters and matched non-adopters using propensity score matching to control for selection bias. The analysis assesses the dose-response relationship between SHC recommendation compliance and yield improvement, identifies district-level and farmer-level characteristics that predict adoption and recommendation compliance, and examines whether the scheme’s benefit varies across the five major soil nutrient dimensions that Tamil Nadu’s agroclimatic zones are characterised by — findings that can inform the SHC scheme’s restructuring under the PM-KISAN digital agriculture platform. --- #### Fast-Track Special Courts, Case Pendency, and Conviction Rates Under the POCSO Act 2012 **Authors:** Preethi Raghavan, Saikumar Nagarajan, Devika Chandrasekhar | **Affiliation:** School of Legal Studies, Cochin University of Science and Technology, Kochi, Kerala, India **Pages:** 89-93 | **Published:** 2026/03/14 | **DOI:** https://doi.org/10.5281/zenodo.19334320 **URL:** https://www.ijama.in/papers?paper=Fast-Track+Special+Courts%2C+Case+Pendency%2C+and+Conviction+Rates+Under+the+POCSO+Act+2012 | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1773643250_IJAMAMAR26V3A0317.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19334320, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19334320 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Fast-Track+Special+Courts%2C+Case+Pendency%2C+and+Conviction+Rates+Under+the+POCSO+Act+2012 | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** POCSO Act, Fast-Track Special Court, conviction rate, child sexual abuse, case pendency, NCRB, judicial performance, attrition, child protection, criminal justice, India, RTI, Supreme Court, survivor rights **Abstract:** The Protection of Children from Sexual Offences (POCSO) Act 2012 represented a landmark legislative intervention in India’s child protection framework, establishing for the first time a comprehensive, child-friendly legal architecture for the prosecution of sexual offences against persons below the age of eighteen, with mandatory Special Courts, time-bound trial completion within one year, and prohibition on revealing the identity of the child survivor. A decade after its enactment, the Act’s promise remains demonstrably unrealised: the National Crime Records Bureau documents a persistent and widening gap between the volume of POCSO cases registered and the number actually brought to conviction, a pattern that scholars of procedural justice and survivor advocates alike characterise as a systemic failure of the criminal justice process rather than a failure of the legislative framework. The establishment of Fast-Track Special Courts under the Centrally Sponsored Fast-Track Special Court Scheme from October 2019 was the Government’s direct policy response to this conviction deficit, but its effectiveness has not been systematically evaluated across states with heterogeneous implementation fidelity. This paper conducts a comparative judicial performance analysis across twelve Indian states, drawing on NCRB 2020-2023 conviction data, the Supreme Court’s POCSO dashboard, and original court records obtained under the Right to Information Act from state High Court registries. The analysis examines conviction rates, case disposal timelines, attrition rates at each stage of the criminal process (FIR to charge-sheet, charge-sheet to trial commencement, trial to disposal), and the relationship between Fast-Track Special Court operationalisation and conviction outcomes. The legal analysis situates the empirical findings within the framework of Article 15(3) of the Constitution, the Directive Principles on child welfare, the UN Convention on the Rights of the Child, and judicial pronouncements on the right to fair trial of child survivors as interpreted in recent Supreme Court jurisprudence. --- #### SHG-Bank Credit Linkage, Savings Mobilisation, and Women’s Economic Empowerment **Authors:** Leena Kumari Panda | **Affiliation:** Department of Economics, Ravenshaw University, Cuttack, Odisha, India **Pages:** 94-97 | **Published:** 2026/03/16 | **DOI:** https://doi.org/10.5281/zenodo.19334360 **URL:** https://www.ijama.in/papers?paper=SHG-Bank+Credit+Linkage%2C+Savings+Mobilisation%2C+and+Women%E2%80%99s+Economic+Empowerment | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1773643383_IJAMAMAR26V3A0318.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19334360, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19334360 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=SHG-Bank+Credit+Linkage%2C+Savings+Mobilisation%2C+and+Women%E2%80%99s+Economic+Empowerment | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** SHG-Bank linkage, women's empowerment, microfinance, DAY-NRLM, NABARD, self-help groups, financial inclusion, intra-household bargaining, poverty exit, Tamil Nadu, Andhra Pradesh, Odisha, longitudinal, credit access, rural development **Abstract:** India’s SHG-Bank Linkage Programme, launched by NABARD in 1992 and subsequently scaled through the Deendayal Antyodaya Yojana – National Rural Livelihoods Mission, represents the world’s largest microfinance programme by reach, connecting an estimated 67 lakh self-help groups and their 9.17 crore women members to the formal banking system as of March 2024. The programme’s foundational design logic — that peer-group solidarity, regular compulsory savings, and demonstrated repayment discipline can substitute for collateral in creditworthiness assessment, thereby overcoming the information asymmetry barrier that excludes rural women from formal credit — has been validated in principle by the programme’s remarkably low non-performing asset rates relative to other rural lending portfolios. Yet the extent to which credit access translates into the deeper empowerment outcomes that motivate the programme’s continued public investment — decision-making autonomy, mobility, asset ownership, reduced vulnerability to economic shocks — remains contested in the empirical literature. The geographical diversity of SHG programme implementation across India creates natural experimental variation that this study exploits. Andhra Pradesh and Telangana, where the Velugu and IKP missions have operated since the early 2000s with a saturation model covering virtually all rural women through SHGs, represent the programme’s most mature ecosystem, with SHG members in their second or third credit cycle and multi-generational SHG participation in some clusters. Tamil Nadu’s TNSRLM represents an intermediate maturity tier, with strong bank linkage coverage but a shorter average membership duration. Odisha represents the programme’s expanding frontier, with rapid recent growth in DAY-NRLM coverage creating a population of recent joiners whose trajectories can be compared to the more mature SHG populations in the southern states. This longitudinal study tracks a cohort of women SHG members across these three states at four time points — at programme entry and at one, three, and five or more years of membership — measuring empowerment across six dimensions: economic decision-making, financial services access, mobility and freedom of movement, self-confidence and public voice, asset ownership, and children’s education decision-making. The study’s specific analytical contribution is to disaggregate the empowerment trajectory by state, by SHG grading (NABARD grading criteria), and by credit cycle access, enabling estimation of the marginal empowerment returns to SHG membership duration, to credit access beyond savings linkage, and to skill training completion that distinguishes active from passive participation in the SHG programme. The economics of women’s empowerment in this context connects to two broader debates in development economics: the microfinance effectiveness literature, which since Banerjee et al.’s (2015) Andhra Pradesh randomised evaluation has grappled with the gap between credit access and transformative empowerment outcomes; and the intra-household bargaining literature, which predicts that women’s control over earned income and credit resources shifts bargaining power toward household investments in children’s health and education that create inter-generational poverty exit pathways beyond the immediate income gains from SHG participation. --- #### Glycaemic Control, Self-Care Practices and Structured Education among Type 2 Diabetics in South India **Authors:** Elena Marchetti | **Affiliation:** Department of Diabetology, University of Bologna, Bologna, Italy **Pages:** 98-103 | **Published:** 2026/03/25 | **DOI:** https://doi.org/10.5281/zenodo.19334422 **URL:** https://www.ijama.in/papers?paper=Glycaemic+Control%2C+Self-Care+Practices+and+Structured+Education+among+Type+2+Diabetics+in+South+India | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1774871908_IJAMAMAR26V3A0319.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19334422, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19334422 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Glycaemic+Control%2C+Self-Care+Practices+and+Structured+Education+among+Type+2+Diabetics+in+South+India | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** Type 2 Diabetes, glycaemic control, HbA1c, self-care, diabetes education, DSME, South India, Tamil Nadu, Karnataka, public health **Abstract:** Type 2 Diabetes Mellitus (T2DM) constitutes a substantial and escalating public health burden across India, with South Indian states exhibiting some of the highest age-standardised prevalence rates in the nation, driven by a convergence of rapid dietary transition, declining physical activity, genetic susceptibility, and urbanisation. This study investigates the determinants of glycaemic control among T2DM patients attending outpatient diabetic clinics in Tamil Nadu and Karnataka, examining the role of structured diabetes education programmes in modifying self-care behaviours and improving HbA1c outcomes over a six-month intervention period. The study enrolled 4,218 participants across twelve clinical sites stratified by urban, peri-urban, and rural location. Baseline HbA1c, fasting plasma glucose, BMI, blood pressure, and lipid profiles were recorded, along with validated self-care scores across dietary adherence, physical activity, medication compliance, blood glucose monitoring, and foot care domains. Participants in the intervention arm received a structured twelve-session Diabetes Self-Management Education (DSME) programme delivered by trained diabetes nurse educators and dieticians, with motivational interviewing components incorporated after session four. At six-month follow-up, intervention arm participants showed a mean HbA1c reduction of 1.9 percentage points compared to 0.4 in the control arm (p<0.001). Self-care scores improved significantly across all five domains in the intervention group. Multivariable logistic regression identified rural residence, sedentary lifestyle, family history, and overweight as independent risk factors for poor glycaemic control, while DSME completion emerged as the strongest protective predictor (adjusted OR 0.52, 95% CI 0.39-0.69). The study provides evidence for scaling structured patient education in primary and secondary care settings across South India as a cost-effective strategy for improving population-level glycaemic outcomes. --- #### Ambient Air Quality Assessment and Respiratory Health Outcomes in Urban and Industrial Zones of Maharashtra **Authors:** Marco Trevisan | **Affiliation:** Department of Civil and Environmental Engineering, Politecnico di Milano, Milan, Italy **Pages:** 104-109 | **Published:** 2026/03/25 | **DOI:** https://doi.org/10.5281/zenodo.19334478 **URL:** https://www.ijama.in/papers?paper=Ambient+Air+Quality+Assessment+and+Respiratory+Health+Outcomes+in+Urban+and+Industrial+Zones+of+Maharashtra | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1774872245_IJAMAMAR26V3A0320.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19334478, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19334478 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Ambient+Air+Quality+Assessment+and+Respiratory+Health+Outcomes+in+Urban+and+Industrial+Zones+of+Maharashtra | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** air quality, PM2.5, PM10, respiratory health, Maharashtra, ambient monitoring, DLNM, asthma, COPD, environmental epidemiology **Abstract:** Rapid urbanisation and industrial expansion in Maharashtra have contributed to persistent deterioration of ambient air quality, generating measurable adverse respiratory health outcomes in exposed populations. This study presents a systematic assessment of six key air pollutants — PM2.5, PM10, NO2, SO2, CO, and ground-level ozone — measured across thirty monitoring stations in Pune, Mumbai, and Nagpur Metropolitan Regions over a twenty-four-month continuous monitoring period. Simultaneously, respiratory morbidity data including incidence rates of asthma exacerbation, chronic obstructive pulmonary disease hospitalisations, and upper respiratory tract infection consultations were extracted from district health records for the same temporal and spatial frame. Industrial zone monitoring stations recorded PM2.5 levels averaging 124.6 μg/m³, exceeding the WHO annual guideline of 15 μg/m³ by more than eightfold. Urban residential zones recorded lower but still severely elevated levels of 87.4 μg/m³. Distributed lag non-linear model analysis identified a significant lagged association between PM2.5 and PM10 concentrations and respiratory hospital admissions at lags of two to seven days. Every 10 μg/m³ increase in PM2.5 was associated with a 6.8 percent increase in asthma emergency department visits (95% CI 5.2-8.4%) and a 4.3 percent increase in COPD exacerbation hospitalisations (95% CI 3.1-5.5%). The Italian collaborative team's contribution validated the spatiotemporal interpolation methodology using kriging models previously applied in northern Italian industrial corridors. --- #### Perceived Academic Stress, Psychological Wellbeing, and Sleep Quality among Undergraduate Students — A Cross-Sectional Study **Authors:** Sophie Renard, Lucas Hoffmann, Isabelle Moreau, Tobias Schreiber, Elena Vasquez | **Affiliation:** Department of Psychology and Cognitive Neuroscience, University of Strasbourg, Strasbourg, France **Pages:** 110-116 | **Published:** 2026/04/28 | **DOI:** https://doi.org/10.5281/zenodo.19334539 **URL:** https://www.ijama.in/papers?paper=Perceived+Academic+Stress%2C+Psychological+Wellbeing%2C+and+Sleep+Quality+among+Undergraduate+Students+%E2%80%94+A+Cross-Sectional+Study | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1774872418_IJAMAMAR26V3A0321.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19334539, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19334539 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Perceived+Academic+Stress%2C+Psychological+Wellbeing%2C+and+Sleep+Quality+among+Undergraduate+Students+%E2%80%94+A+Cross-Sectional+Study | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 3, March 2026 **Keywords:** academic stress, PSS-10, undergraduate students, mental health, sleep quality, GPA, anxiety, depression, WHOQOL, university wellbeing **Abstract:** Academic stress is a pervasive phenomenon among university undergraduates globally, generating cascading effects on psychological wellbeing, sleep architecture, and scholastic performance. This cross-sectional study examined the prevalence and severity of perceived academic stress among 2,847 undergraduate students enrolled across five faculties of the University of Strasbourg using the Perceived Stress Scale (PSS-10), and investigated its associations with depression symptoms (PHQ-9), generalised anxiety (GAD-7), quality of life (WHOQOL-BREF), sleep duration and quality (Pittsburgh Sleep Quality Index), and cumulative grade point average. Structured cluster sampling stratified by faculty and year of study was employed. Results revealed that 38.4 percent of participants met criteria for high perceived stress (PSS-10 above 27), with first-year students and those in medical and competitive professional programmes showing the highest prevalence. High-stress participants demonstrated significantly lower GPAs (mean 2.74 vs. 3.61 in low-stress controls), shorter sleep duration (mean 4.8 vs. 7.4 hours), and markedly elevated PHQ-9 and GAD-7 scores. Multiple regression analysis identified examination frequency, financial insecurity, social isolation, and poor sleep quality as independent predictors of PSS-10 score, with examination frequency accounting for the largest proportion of explained variance. Mediation analysis indicated that sleep quality partially mediated the relationship between perceived stress and academic performance, explaining 31.4 percent of the total stress-GPA association. The findings provide a quantitative evidence base for targeted university mental health interventions, advocating for restructured examination scheduling, --- ### Issue 4 — April 2026 — https://www.ijama.in/archives.php?volume=3&issue=4 #### Accelerated Glacier Retreat, Mass Balance Deficits, and Downstream Hydrological Consequences Across Six Mountain Regions (2000-2024) **Authors:** Petra Hoffmann, Jean-Luc Morard, Anders Lindström, Valentina Conti | **Affiliation:** Department of Glaciology and Climate Science, ETH Zurich, Zurich, Switzerland **Pages:** 1-6 | **Published:** 2026/04/01 | **DOI:** https://doi.org/10.5281/zenodo.19438167 **URL:** https://www.ijama.in/papers?paper=Accelerated+Glacier+Retreat%2C+Mass+Balance+Deficits%2C+and+Downstream+Hydrological+Consequences+Across+Six+Mountain+Regions+%282000-2024%29 | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775137550_IJAMAAPR26V4A0401.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19438167, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19438167 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Accelerated+Glacier+Retreat%2C+Mass+Balance+Deficits%2C+and+Downstream+Hydrological+Consequences+Across+Six+Mountain+Regions+%282000-2024%29 | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** glacier retreat, mass balance, cryosphere, sea level rise, remote sensing, Landsat, DEM differencing, hydrological regime shift, European Alps, climate change **Abstract:** Mountain glaciers are among the most sensitive indicators of atmospheric warming, responding to temperature and precipitation changes on decadal timescales through area loss, thickness reduction, and mass balance deficits that collectively constitute the cryosphere's contribution to observed sea level rise. The acceleration of glacier retreat documented since the 1990s has intensified markedly in the 2010s and early 2020s, with global glacier mass loss in 2021–2023 representing the highest three-year loss on record. This study presents a twenty-four-year remote sensing and field-based analysis of glacier area change, mass balance, and downstream river discharge trends across 124 glaciers spanning six mountain regions — the European Alps, Icelandic Ice Caps, New Zealand Southern Alps, Canadian Rockies, Central Asian Pamirs, and Scandinavian Mountains. Landsat and Sentinel-2 multispectral imagery was used to map glacier outlines at five-year intervals from 2000 to 2024. Geodetic mass balance was estimated from DEM differencing using SRTM and TanDEM-X elevation models. Downstream river discharge records from 214 hydrological stations were analysed for trend and peak-flow timing shifts. Results demonstrate mean area loss of 18.6 percent across all study glaciers, with the European Alps showing the greatest proportional loss (26.4%). Peak streamflow timing advanced by a mean of 22.4 days across downstream basins, signalling transition from glacier-buffered to snowmelt-dominated hydrological regimes. --- #### Bilingual Working Memory, Cognitive Inhibition, and Language Switching Costs — An ERP and Reaction Time Study in Late French-English Bilinguals **Authors:** Céline Dupont, Oliver Krämer, Aiko Yamamoto, Brigitte Leclercq, Thomas Wierzbicki | **Affiliation:** Department of Linguistics and Cognitive Neuroscience, Université libre de Bruxelles, Brussels, Belgium **Pages:** 7-13 | **Published:** 2026/04/01 | **DOI:** https://doi.org/10.5281/zenodo.19438239 **URL:** https://www.ijama.in/papers?paper=Bilingual+Working+Memory%2C+Cognitive+Inhibition%2C+and+Language+Switching+Costs+%E2%80%94+An+ERP+and+Reaction+Time+Study+in+Late+French-English+Bilinguals | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775137776_IJAMAAPR26V4A0402.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19438239, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.19438239 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Bilingual+Working+Memory%2C+Cognitive+Inhibition%2C+and+Language+Switching+Costs+%E2%80%94+An+ERP+and+Reaction+Time+Study+in+Late+French-English+Bilinguals | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** bilingualism, working memory, cognitive inhibition, Stroop task, ERP, N2 component, language switching, executive function, late bilinguals, psycholinguistics **Abstract:** The neurocognitive basis of bilingualism has attracted substantial research attention, particularly regarding whether managing two language systems produces measurable advantages or costs in domain-general executive control functions including working memory, inhibitory control, and cognitive flexibility. The bilingual advantage hypothesis, prominent from approximately 2004 to 2015, has been substantially complicated by subsequent large-sample studies and meta-analyses reporting inconsistent or null effects. This study examined working memory capacity, cognitive inhibition, and language switching costs in 148 late French-English bilinguals and 72 French monolinguals at the Université libre de Bruxelles using event-related potential (ERP) neuroimaging, mixed-language Stroop task reaction times, and N-back working memory paradigms. Results revealed significant language switching costs in the bilingual group, with incongruent Stroop interference effects of 196 ms in the second language (L2) compared to 136 ms in the first language (L1). ERP analysis identified a larger N2 component amplitude in bilinguals during incongruent Stroop trials, suggesting enhanced early conflict monitoring as a bilingual cognitive adaptation. N-back accuracy was significantly lower in L2 conditions (81.3% vs. 88.4% in L1), indicating a working memory cost under dual-language processing demand. Language dominance, switching frequency, and age of L2 acquisition emerged as significant moderators, partially reconciling the inconsistent bilingual advantage literature. --- #### Conservation Tillage, Soil Organic Carbon Sequestration, and Microbial Community Dynamics in Temperate Cereal Cropping Systems **Authors:** Marek Nowak, Annelies Van den Berg, Stefan Brandt | **Affiliation:** Department of Soil Science and Sustainable Agriculture, Wageningen University and Research, Wageningen, Netherlands **Pages:** 14-20 | **Published:** 2026/04/02 | **DOI:** https://doi.org/10.5281/zenodo.19438296 **URL:** https://www.ijama.in/papers?paper=Conservation+Tillage%2C+Soil+Organic+Carbon+Sequestration%2C+and+Microbial+Community+Dynamics+in+Temperate+Cereal+Cropping+Systems | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775138080_IJAMAAPR26V4A0403.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19438296, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.19438296 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Conservation+Tillage%2C+Soil+Organic+Carbon+Sequestration%2C+and+Microbial+Community+Dynamics+in+Temperate+Cereal+Cropping+Systems | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** soil organic carbon, conservation tillage, no-till, microbial biomass, earthworm, soil health, carbon sequestration, temperate cereals, Northwestern Europe, sustainable agriculture **Abstract:** Soil organic carbon (SOC) sequestration in agricultural systems represents a dual-benefit strategy that simultaneously improves soil health and contributes to climate change mitigation. Tillage intensity is the most tractable management lever for influencing SOC dynamics in arable cropping systems, as conventional tillage mechanically disrupts soil aggregates, accelerates organic matter decomposition, and destroys the macropore networks and biological communities that mediate carbon stabilisation. This five-year multi-site randomised block trial examined the effects of conventional tillage (CT), minimum tillage (MT), and no-till (NT) on SOC concentration, soil physical properties, microbial biomass, and earthworm populations across eight experimental sites in the Netherlands, Belgium, and northern Germany. Results demonstrate significant treatment effects on all measured soil parameters after five years, with no-till plots showing 65 percent higher SOC (2.34 vs. 1.42% in CT), 130 percent higher water infiltration (42.3 vs. 18.4 mm/hr), 73 percent higher microbial biomass carbon, and 124 percent higher earthworm density. Crop yields under no-till converged toward conventional tillage equivalence by year three, with mean yield penalties of only 4.2 percent in years four and five. Carbon balance modelling indicates that no-till adoption across the 4.8 million hectares of cereal cropland in northwestern Europe could sequester an additional 2.8 to 4.1 Mt CO₂-equivalent per year. --- #### Hypertension Prevalence, Cardiovascular Risk Stratification, and Major Adverse Cardiac Event Outcomes in a Multi-Centre European Cohort **Authors:** François Beaumont, Katarzyna Wiśniewska, Dimitris Papadopoulos, Lars Eriksson | **Affiliation:** Department of Cardiology and Preventive Medicine, Université Paris Cité, Paris, France **Pages:** 21-26 | **Published:** 2026/04/02 | **DOI:** https://doi.org/10.5281/zenodo.19438342 **URL:** https://www.ijama.in/papers?paper=Hypertension+Prevalence%2C+Cardiovascular+Risk+Stratification%2C+and+Major+Adverse+Cardiac+Event+Outcomes+in+a+Multi-Centre+European+Cohort | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775138231_IJAMAAPR26V4A0404.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19438342, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19438342 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Hypertension+Prevalence%2C+Cardiovascular+Risk+Stratification%2C+and+Major+Adverse+Cardiac+Event+Outcomes+in+a+Multi-Centre+European+Cohort | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** hypertension, cardiovascular disease, MACE, blood pressure, RCT, ESC guidelines, telemedicine, risk stratification, France, preventive cardiology **Abstract:** Hypertension remains the single most prevalent modifiable risk factor for cardiovascular disease globally, contributing to an estimated 10.4 million deaths annually and accounting for a disproportionate share of the cardiovascular disease burden across European populations. Despite substantial advances in antihypertensive pharmacotherapy, rates of blood pressure control remain suboptimal in most European countries, with surveys indicating that fewer than 40 percent of hypertensive individuals achieve the European Society of Cardiology recommended target of below 130/80 mmHg. This prospective multi-centre cohort study enrolled 6,248 hypertensive adults aged 40–80 years across twelve cardiology clinics in France, Poland, Greece, and Sweden, following participants for five years to characterise major adverse cardiac event (MACE) outcomes, blood pressure trajectory, and modifiable risk factor burden. A structured cardiovascular risk reduction intervention combining intensified antihypertensive pharmacotherapy, lifestyle modification counselling, and telemedicine-supported home blood pressure monitoring was tested against standard care in a randomised sub-cohort (n=6,248; 3,124 per arm). The intervention arm achieved a mean systolic blood pressure reduction of 34.0 mmHg from baseline (158.4 to 124.4 mmHg) compared to 6.0 mmHg in the control arm. Five-year MACE-free survival was significantly higher in the intervention arm (83.9% vs. 72.6%; HR=0.68, 95% CI 0.58–0.79, p<0.001). Multivariable regression identified age above 65, smoking, diabetes, and physical inactivity as the strongest independent predictors of MACE outcomes. --- #### Microplastic Contamination in Freshwater and Coastal Ecosystems — Spatial Distribution, Polymer Characterisation, and Source Attribution Across Northwestern Europe **Authors:** Emilia Johansson, Gerard van Houten, Marie-Claire Fontaine, Aleksander Nowicki | **Affiliation:** Department of Environmental Chemistry and Analytical Sciences, Stockholm University, Stockholm, Sweden **Pages:** 27-33 | **Published:** 2026/04/02 | **DOI:** https://doi.org/10.5281/zenodo.19438387 **URL:** https://www.ijama.in/papers?paper=Microplastic+Contamination+in+Freshwater+and+Coastal+Ecosystems+%E2%80%94+Spatial+Distribution%2C+Polymer+Characterisation%2C+and+Source+Attribution+Across+Northwestern+Europe | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775138431_IJAMAAPR26V4A0405.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19438387, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19438387 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Microplastic+Contamination+in+Freshwater+and+Coastal+Ecosystems+%E2%80%94+Spatial+Distribution%2C+Polymer+Characterisation%2C+and+Source+Attribution+Across+Northwestern+Europe | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** microplastics, freshwater contamination, ATR-FTIR, polymer characterisation, source attribution, positive matrix factorisation, seasonal variation, urban rivers, Northwestern Europe, environmental chemistry **Abstract:** Microplastic contamination of freshwater and coastal ecosystems has emerged as a critical environmental challenge, with particles detected in virtually every aquatic matrix sampled globally — from Arctic sea ice to remote mountain lakes — yet the quantitative spatial distribution, polymer composition, and source attribution of microplastic loads across connected freshwater-coastal continua remain incompletely characterised in European contexts. This study presents a systematic multi-site sampling campaign across 84 aquatic monitoring locations in Sweden, the Netherlands, France, and Poland, spanning six water body typologies — urban rivers, peri-urban rivers, rural streams, coastal zones, stratified lakes, and groundwater — sampled seasonally over a two-year period (2022–2023). A total of 6,482 individual microplastic particles were characterised by attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR) for polymer type identification. Urban rivers showed the highest mean concentrations (1,842 particles/m³) and coastal zones the second highest (2,284 particles/m³), driven by wastewater effluent discharge and urban stormwater runoff. Positive matrix factorisation source attribution identified wastewater effluent (34.2%) and urban runoff (22.8%) as the dominant freshwater microplastic sources. Seasonal variation was significant, with summer concentrations 38–52 percent higher than winter values, consistent with increased recreational plastic use and reduced dilution under lower summer discharge. --- #### Urban Housing Inequality, Informal Settlements, and Social Mobility Outcomes in Indian Megacities **Authors:** Rahul Desai, Meena Kapoor | **Affiliation:** Department of Urban Planning and Built Environment, , Maharashtra, India **Pages:** 34-40 | **Published:** 2026/04/05 | **DOI:** https://doi.org/10.5281/zenodo.19438428 **URL:** https://www.ijama.in/papers?paper=Urban+Housing+Inequality%2C+Informal+Settlements%2C+and+Social+Mobility+Outcomes+in+Indian+Megacities | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775462517_IJAMAAPR26V4A0406.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19438428, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19438428 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Urban+Housing+Inequality%2C+Informal+Settlements%2C+and+Social+Mobility+Outcomes+in+Indian+Megacities | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** urban housing inequality, informal settlements, slums, social mobility, India, rent burden, Pradhan Mantri Awas Yojana, housing affordability, intergenerational mobility, urban planning **Abstract:** Housing constitutes the foundational material condition of urban life in India, determining not only shelter quality and tenure security but also access to employment, education, healthcare, and social networks that collectively define the social mobility pathways available to the 500 million Indians who now live in urban areas. India's rapid urbanisation — with the urban population projected to reach 600 million by 2031 — has outpaced formal housing production dramatically, generating one of the world's largest informal settlement populations. An estimated 65 million Indians live in slums and unauthorised colonies, according to the 2011 Census, a figure widely considered an undercount given the exclusion of non-notified informal settlements from official enumeration. This study presents a comparative cross-city analysis of housing inequality indicators, informal settlement prevalence, and social mobility outcomes across forty Indian cities and twenty cities from comparable emerging economies, drawing on National Family Health Survey, Census of India, and National Sample Survey data supplemented by World Bank and UN-Habitat global urban datasets covering the period 2015-2023. Multi-level regression models examined the associations between housing cost burden (rent-to-income ratio), informal settlement share, and measures of intergenerational educational mobility, occupational attainment gaps between housing tenure groups, and subjective wellbeing outcomes. Results demonstrate that Indian cities with rent-to-income ratios above 0.40 show significantly lower intergenerational educational mobility, and that informal settlement share is the strongest single predictor of educational attainment gap between housing tenure groups. --- #### Dietary Adherence to a Structured Nutrition Intervention and Cardiometabolic Risk Reduction in Middle-Aged Adults with Metabolic Syndrome **Authors:** Priya Sharma, Arun Mehta, Sunita Rao | **Affiliation:** Department of Endocrinology and Metabolism, All India Institute of Medical Sciences (AIIMS), New Delhi, India **Pages:** 43-47 | **Published:** 2026/04/05 | **DOI:** https://doi.org/10.5281/zenodo.19438466 **URL:** https://www.ijama.in/papers?paper=Dietary+Adherence+to+a+Structured+Nutrition+Intervention+and+Cardiometabolic+Risk+Reduction+in+Middle-Aged+Adults+with+Metabolic+Syndrome | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775462672_IJAMAAPR26V4A0407.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19438466, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.19438466 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Dietary+Adherence+to+a+Structured+Nutrition+Intervention+and+Cardiometabolic+Risk+Reduction+in+Middle-Aged+Adults+with+Metabolic+Syndrome | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** dietary intervention, cardiometabolic risk, metabolic syndrome, LDL cholesterol, CRP, IL-6, RCT, Indian diet, AIIMS, cardiovascular prevention **Abstract:** Cardiometabolic disease, encompassing type 2 diabetes mellitus, dyslipidaemia, hypertension, and cardiovascular disease, represents the dominant cause of preventable premature mortality across India and globally. Structured dietary interventions combining low glycaemic index whole foods, increased legume and fibre intake, reduced refined carbohydrates, and moderate healthy fat consumption from sources including groundnut, mustard, and coconut oil have accumulated substantial observational and interventional evidence for cardiometabolic benefit in the Indian population context. This randomised controlled trial examined the effect of a structured twelve-month dietary adherence intervention, culturally adapted to Indian dietary traditions, on a comprehensive panel of cardiometabolic biomarkers in middle-aged adults with metabolic syndrome criteria at AIIMS New Delhi. A total of 386 participants aged 40-65 years meeting at least three International Diabetes Federation criteria for metabolic syndrome were randomised to a dietary intervention arm (n=193) receiving monthly dietitian-led counselling, culturally adapted meal planning support incorporating regional Indian cuisine, and dietary supplementation with cold-pressed groundnut oil, or a control arm (n=193) receiving general dietary advice pamphlets. Primary outcomes included change in BMI, waist circumference, fasting glucose, LDL-cholesterol, HDL-cholesterol, and inflammatory biomarkers CRP and IL-6. At twelve-month follow-up, the intervention arm demonstrated statistically significant improvements across all primary outcomes compared to controls, including a mean fasting glucose reduction of 14.1 mg/dL (p<0.001), LDL-C reduction of 26.4 mg/dL (p<0.001), and CRP reduction of 2.5 mg/L (p<0.001). Dietary Score adherence correlated strongly with biomarker improvement magnitude (r=0.67, p<0.001). --- #### Thermal Bleaching Events, Species-Specific Recovery Trajectories, and Reef Biodiversity Loss in the Lakshadweep Archipelago and Andaman Reefs **Authors:** Vikram Nair, Deepa Krishnamurthy, Rajesh Patel, Ananya Bose | **Affiliation:** Department of Marine Sciences and Coastal Ecology, Goa University, Panaji, Goa, India **Pages:** 48-54 | **Published:** 2026/04/06 | **DOI:** https://doi.org/10.5281/zenodo.19438494 **URL:** https://www.ijama.in/papers?paper=Thermal+Bleaching+Events%2C+Species-Specific+Recovery+Trajectories%2C+and+Reef+Biodiversity+Loss+in+the+Lakshadweep+Archipelago+and+Andaman+Reefs | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775462820_IJAMAAPR26V4A0408.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19438494, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19438494 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Thermal+Bleaching+Events%2C+Species-Specific+Recovery+Trajectories%2C+and+Reef+Biodiversity+Loss+in+the+Lakshadweep+Archipelago+and+Andaman+Reefs | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** coral bleaching, Lakshadweep, Andaman reefs, sea surface temperature, reef biodiversity, Acropora, recovery index, Indian Ocean, NOAA CRW, marine ecology **Abstract:** India's tropical coral reef ecosystems — centred on the Lakshadweep Islands in the Arabian Sea, the Andaman and Nicobar Islands in the Bay of Bengal, and the Gulf of Mannar fringing reefs along the Tamil Nadu coast — support exceptional marine biodiversity and provide critical ecosystem services to coastal and island communities including fisheries, coastal protection, and tourism valued at over INR 18,000 crore annually. Accelerating sea surface temperature rise in the Indian Ocean, amplified by the Indian Ocean Dipole and periodic El Niño-Southern Oscillation events, has transformed mass coral bleaching from a rare disturbance into a recurring annual threat, with the 2019 and 2022 bleaching events representing the two most severe thermal stress episodes recorded in the Indian reef monitoring period. This study presents a five-year longitudinal analysis (2019-2024) of bleaching severity, species-specific recovery trajectories, and cumulative biodiversity indicators across eighteen permanent reef monitoring stations across the Lakshadweep and Andaman reef systems. Sea surface temperature anomalies from NOAA Coral Reef Watch satellite data were linked to in-situ bleaching severity assessments conducted by trained reef surveyors. Results demonstrate that bleaching severity in 2022 exceeded 2019 levels at all stations, with branching Acropora and Montipora species showing the lowest recovery indices (0.19-0.34). Overall coral cover declined from 38.4 percent in 2019 to 24.7 percent in 2024, a 35.7 percent reduction. Shannon diversity index declined significantly, driven by disproportionate loss of thermally sensitive branching coral morphologies. --- #### Antimicrobial Resistance Surveillance in Hospital-Acquired Gram-Negative Infections **Authors:** Suresh Kumar Sharma, Anita Patel, Rajiv Mohan | **Affiliation:** Department of Clinical Microbiology and Infectious Diseases, All India Institute of Medical Sciences (AIIMS), New Delhi, India **Pages:** 55-61 | **Published:** 2026/04/07 | **DOI:** https://doi.org/10.5281/zenodo.19482934 **URL:** https://www.ijama.in/papers?paper=Antimicrobial+Resistance+Surveillance+in+Hospital-Acquired+Gram-Negative+Infections | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775734725_IJAMAAPR26V4A0409.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19482934, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19482934 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Antimicrobial+Resistance+Surveillance+in+Hospital-Acquired+Gram-Negative+Infections | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** antimicrobial resistance, carbapenem resistance, CRE, ESBL, Klebsiella pneumoniae, E. coli, ICU, hospital-acquired infections, AMR surveillance, Indian hospitals **Abstract:** Antimicrobial resistance (AMR) in hospital-acquired Gram-negative bacterial infections represents one of the most urgent threats to global health security, with carbapenem-resistant Enterobacteriaceae (CRE), extended-spectrum beta-lactamase-producing organisms (ESBL), and multidrug-resistant Pseudomonas aeruginosa collectively accounting for an estimated 700,000 deaths annually from AMR-attributable infections. Indian tertiary care intensive care units represent epicentres of AMR selection pressure, combining critically ill immunocompromised patients, prolonged antibiotic exposures, device-associated infection risk, and the cross-transmission dynamics of high-density care environments. This study presents a four-year retrospective surveillance analysis (2020-2024) of antimicrobial resistance rates in Gram-negative hospital-acquired infections across twenty-two ICUs in eight major Indian cities, examining temporal trends in resistance to first-line, second-line, and last-resort antimicrobial agents. Microbiological data from 18,742 clinical isolates of Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa were extracted from participating institutions' laboratory information systems and linked to clinical outcome data including ICU length of stay, 30-day mortality, and antimicrobial treatment duration. Resistance rates across fourteen antimicrobial classes were calculated annually per organism. Results demonstrate a consistent temporal escalation in resistance across all three organisms and nearly all antimicrobial classes, with the most alarming trajectory observed for carbapenem resistance in K. pneumoniae (8.7% in 2020 to 18.3% in 2024) and meropenem resistance in E. coli (4.2% to 9.8%). Multivariable Cox regression identified carbapenem resistance as the strongest predictor of 30-day mortality (HR 3.42, 95% CI 2.87-4.07), confirming the clinical severity of the resistance escalation trend. --- #### Frailty Prevalence, Multidomain Intervention Effects, and Hospitalisation Reduction in Community-Dwelling Older Adults **Authors:** María José Fernández, Thomas Bergström, Agnès Lefebvre, Risto Heikkinen, Chiara Bellini | **Affiliation:** Department of Geriatric Medicine and Ageing Research, University of Barcelona, Barcelona, Spain **Pages:** 62-68 | **Published:** 2026/04/07 | **DOI:** https://doi.org/10.5281/zenodo.19482984 **URL:** https://www.ijama.in/papers?paper=Frailty+Prevalence%2C+Multidomain+Intervention+Effects%2C+and+Hospitalisation+Reduction+in+Community-Dwelling+Older+Adults | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775735305_IJAMAAPR26V4A04010.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19482984, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19482984 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Frailty+Prevalence%2C+Multidomain+Intervention+Effects%2C+and+Hospitalisation+Reduction+in+Community-Dwelling+Older+Adults | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** frailty, older adults, RCT, multidomain intervention, Frailty Index, gait speed, hospitalisation, sarcopenia, nutritional supplementation, geriatric medicine **Abstract:** Frailty — the age-associated reduction in physiological reserve across multiple organ systems, characterised by vulnerability to stressors and disproportionate health consequences from minor insults — is both a major predictor of adverse outcomes in older adults and a potentially modifiable target for preventive intervention. Despite high prevalence estimates of 10–15 percent for frailty and 40–50 percent for the pre-frail state in community-dwelling adults above 70 years, evidence-based multidomain intervention programmes targeting the biological and functional components of frailty simultaneously remain under-evaluated in randomised controlled designs with long-term outcome follow-up. This two-year RCT enrolled 8,641 community-dwelling adults aged 60 and above across fifteen geriatric outpatient clinics in Spain, Sweden, France, Finland, and Italy, screening for frailty using the Fried Frailty Phenotype and the Frailty Index, and randomising pre-frail and frail participants to a structured multidomain intervention or standard geriatric care. The multidomain intervention combined structured progressive resistance and balance exercise (three sessions per week), protein-targeted nutritional supplementation (1.2 g/kg/day), cognitive stimulation therapy, and polypharmacy review by a clinical pharmacist. At twenty-four months, the intervention arm showed significant reductions in Frailty Index score (0.28 to 0.16 vs. 0.27 to 0.31 in controls), gait speed improvement (0.24 m/s increase vs. 0.02 m/s in controls), and a 41.2 percent reduction in hospital admissions relative to the control arm. Frailty reversal — transition from frail to pre-frail or robust — was achieved in 34.8 percent of intervention arm participants compared to 8.4 percent in controls. --- #### Sleep Architecture Abnormalities, Cognitive Performance Deficits, and CBT-I Efficacy in Adults with Chronic Insomnia Disorder **Authors:** Isabelle Marchand, Pieter de Vries, Klaus Hoffmeister, Anna Sørensen | **Affiliation:** Department of Sleep Medicine and Cognitive Neuroscience, Radboud University Medical Centre, Nijmegen, Netherlands **Pages:** 69-75 | **Published:** 2026/04/08 | **DOI:** https://doi.org/10.5281/zenodo.19483156 **URL:** https://www.ijama.in/papers?paper=Sleep+Architecture+Abnormalities%2C+Cognitive+Performance+Deficits%2C+and+CBT-I+Efficacy+in+Adults+with+Chronic+Insomnia+Disorder | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775735954_IJAMAAPR26V4A04011.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19483156, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19483156 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Sleep+Architecture+Abnormalities%2C+Cognitive+Performance+Deficits%2C+and+CBT-I+Efficacy+in+Adults+with+Chronic+Insomnia+Disorder | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** insomnia, CBT-I, sleep architecture, polysomnography, EEG spectral analysis, ISI, WASO, slow-wave sleep, cognitive performance, sleep hygiene **Abstract:** Chronic insomnia disorder, defined by persistent difficulty initiating or maintaining sleep with associated daytime impairment occurring at least three nights per week for three or more months, is the most prevalent sleep disorder in Europe, affecting an estimated 10–15 percent of adults and generating substantial individual burden through impaired cognitive performance, emotional dysregulation, and elevated risk of depression, anxiety, and cardiovascular disease. Despite evidence-based cognitive behavioural therapy for insomnia (CBT-I) representing the recommended first-line treatment over pharmacotherapy in all major clinical guidelines, access to trained CBT-I therapists remains severely limited across European healthcare systems. This randomised controlled trial compared six-week group CBT-I with a sleep hygiene education control in 400 adults with polysomnography-confirmed chronic insomnia disorder, evaluating the effects on sleep architecture (PSG), EEG spectral power, Insomnia Severity Index, actigraphy parameters, and next-day cognitive performance over a twenty-four-week follow-up. CBT-I produced significant improvements across all primary outcomes. Insomnia Severity Index score declined from 18.4 to 5.2 at week twenty-four (remission rate 68.4%) compared to 18.2 to 16.0 in the sleep hygiene control (remission rate 12.8%). PSG-measured sleep efficiency improved from 68.4 to 84.2 percent in the CBT-I arm, with significant reductions in wake after sleep onset (WASO: from 82.4 to 34.8 minutes) and sleep onset latency. EEG spectral analysis revealed significantly higher delta power and lower beta power during NREM sleep in CBT-I responders at follow-up, consistent with restoration of slow-wave sleep drive and reduction of cortical hyperarousal. Next-day cognitive performance improved significantly in the attention, working memory, and executive function domains. --- #### Nudge Architectures, Default Effects, and Long-Term Pension Enrolment Persistence **Authors:** Lars Andersen, Sophie Leclerc, Heinrich Vogel, Miriam van der Berg | **Affiliation:** Department of Behavioural Economics and Public Policy, Copenhagen Business School, Copenhagen, Denmark **Pages:** 76-82 | **Published:** 2026/04/08 | **DOI:** https://doi.org/10.5281/zenodo.19483306 Style APA **URL:** https://www.ijama.in/papers?paper=Nudge+Architectures%2C+Default+Effects%2C+and+Long-Term+Pension+Enrolment+Persistence | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775736553_IJAMAAPR26V4A04012.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19483306 Style APA, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19483306 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Nudge+Architectures%2C+Default+Effects%2C+and+Long-Term+Pension+Enrolment+Persistence | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** nudge, behavioural economics, pension enrolment, default effect, social norms, loss aversion, field experiment, retirement savings, financial behaviour, public policy **Abstract:** Occupational pension savings rates across Europe remain systematically below levels required to sustain pre-retirement living standards for the majority of workers, generating projected retirement income adequacy deficits that will intensify as demographic ageing erodes pay-as-you-go public pension systems. Behavioural economics offers a toolkit of low-cost nudge interventions — default enrolment, social norm messaging, loss and gain framing, and combined nudge architectures — that have demonstrated substantial enrolment effects in US and UK defined-contribution pension contexts, but their comparative efficacy, long-term persistence, and socioeconomic heterogeneity across Continental European pension systems has not been evaluated in a rigorous multi-country pre-registered field experiment. This study presents a pre-registered randomised field experiment conducted across 4,284 employees in six European countries — Denmark, Germany, France, the Netherlands, Poland, and Austria — testing five nudge conditions against a status quo control in the context of voluntary supplementary pension scheme enrolment. The default-on (opt-out) condition produced the largest immediate enrolment effect (62.8% vs. 18.4% in control; OR=7.42), while the combined nudge condition achieved 71.4% enrolment. Social norm messaging (44.2%) and loss framing (48.6%) produced intermediate effects. At fifty-two weeks post-intervention, enrolment persistence was highest for the default-on condition (63.2%), confirming that default effects are structurally embedded rather than dependent on continued attention. Subgroup analyses identified low-income workers and those with low financial numeracy as the highest-benefit population segments, showing enrolment effects 12–18 percentage points above the overall treatment mean, confirming the equity-improving potential of well-designed pension nudge architectures. --- #### PD-1/PD-L1 Checkpoint Immunotherapy vs. Standard Chemotherapy in Advanced Non-Small Cell Lung Cancer **Authors:** Natalia Petrova, Björn Magnusson, Chiara Romano, Emre Yıldız | **Affiliation:** Department of Medical Oncology and Immunotherapy, Karolinska University Hospital, Stockholm, Sweden **Pages:** 83-89 | **Published:** 2026/04/08 | **DOI:** https://doi.org/10.5281/zenodo.19483861 **URL:** https://www.ijama.in/papers?paper=PD-1%2FPD-L1+Checkpoint+Immunotherapy+vs.+Standard+Chemotherapy+in+Advanced+Non-Small+Cell+Lung+Cancer | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775736714_IJAMAAPR26V4A04013.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19483982, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19483982 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=PD-1%2FPD-L1+Checkpoint+Immunotherapy+vs.+Standard+Chemotherapy+in+Advanced+Non-Small+Cell+Lung+Cancer | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** NSCLC, immunotherapy, PD-1, PD-L1, pembrolizumab, checkpoint inhibitor, TMB, irAE, progression-free survival, lung cancer **Abstract:** Non-small cell lung cancer (NSCLC) accounts for approximately 85 percent of all lung cancer diagnoses globally and remains the leading cause of cancer-related mortality, with five-year survival rates below 20 percent for patients presenting with metastatic disease at diagnosis. The development of immune checkpoint inhibitors targeting the PD-1/PD-L1 axis has fundamentally transformed first-line treatment paradigms for advanced NSCLC over the past decade, demonstrating superior progression-free and overall survival compared to platinum-based chemotherapy in patients with PD-L1 expression above 50 percent. However, the optimal biomarker strategy for patient selection, the management of immune-related adverse events (irAEs), and the comparative efficacy across PD-L1 expression subgroups remain incompletely characterised in European population cohorts. This phase III randomised controlled trial enrolled 624 patients with treatment-naive advanced NSCLC (stage IIIB/IV) across eight oncology centres in Sweden, Italy, Turkey, and Germany. Patients were randomised 1:1 to pembrolizumab plus chemotherapy versus chemotherapy alone, stratified by PD-L1 expression, histological subtype, and ECOG performance status. Primary endpoints were progression-free survival (PFS) and overall survival (OS); secondary endpoints included objective response rate (ORR), irAE profile, tumour mutational burden (TMB) correlation, and quality of life. The immunotherapy arm demonstrated a median PFS of 18.4 months versus 8.2 months in the chemotherapy arm (HR=0.52, 95% CI 0.41–0.66, p<0.001), with PD-L1 ≥50% patients showing an ORR of 64.6 percent. --- #### Photovoltaic System Performance, Degradation Rates, and Levelised Cost of Energy Across Three Panel Technologies **Authors:** David Hartmann, Ingrid Skovdal, Álvaro Medina | **Affiliation:** Department of Renewable Energy Systems and Photovoltaics, Fraunhofer Institute for Solar Energy Systems ISE, Freiburg, Germany **Pages:** 90-96 | **Published:** 2026/04/09 | **DOI:** https://doi.org/10.5281/zenodo.19484239 **URL:** https://www.ijama.in/papers?paper=Photovoltaic+System+Performance%2C+Degradation+Rates%2C+and+Levelised+Cost+of+Energy+Across+Three+Panel+Technologies | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775740497_IJAMAAPR26V4A04014.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19484239, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19484239 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Photovoltaic+System+Performance%2C+Degradation+Rates%2C+and+Levelised+Cost+of+Energy+Across+Three+Panel+Technologies | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** photovoltaics, solar energy, performance ratio, degradation rate, LCOE, mono-Si, thin-film, single-axis tracking, REPowerEU, energy transition **Abstract:** The European Union's REPowerEU plan targets 600 GW of installed solar photovoltaic capacity by 2030, requiring an unprecedented acceleration in deployment across diverse climatic, regulatory, and grid-integration contexts. The long-term techno-economic performance of photovoltaic installations — encompassing annual energy yield, performance ratio, degradation rate, and levelised cost of energy — varies substantially across panel technologies, mounting configurations, and geographic locations in ways that are not fully captured by short-term laboratory measurements or manufacturer specifications. This study presents a five-year field performance assessment of 84 photovoltaic installations across Germany, Spain, and Sweden, covering three panel technologies — monocrystalline silicon (mono-Si), polycrystalline silicon (poly-Si), and cadmium telluride thin-film (CdTe) — and three mounting configurations — fixed tilt, single-axis tracking, and dual-axis tracking. Mono-Si fixed-tilt systems demonstrated the highest mean performance ratio (PR=0.84 at installation, declining to 0.80 at sixty months), while CdTe thin-film showed the lowest degradation rate (0.3% per year vs. 0.5% for mono-Si and 0.5% for poly-Si). Single-axis tracking increased annual energy yield by 18.4–22.6% over fixed tilt across all technologies. LCOE for the best-performing configuration (single-axis mono-Si) reached EUR 34.2/MWh at the German sites under current financing conditions — competitive with all conventional generation sources and enabling direct grid parity across all study locations without subsidy --- #### High-Intensity Interval Training vs. Moderate Continuous Exercise — Effects on VO₂max, Lactate Threshold, Heart Rate Variability, and Body Composition in Sedentary Adults **Authors:** Erik Andersen, Fiona MacLeod, Lukas Becker, Caterina Esposito | **Affiliation:** Department of Exercise Physiology and Sports Medicine, Norwegian School of Sport Sciences, Oslo, Norway **Pages:** 97-103 | **Published:** 2026/04/09 | **DOI:** https://doi.org/10.5281/zenodo.19484289 **URL:** https://www.ijama.in/papers?paper=High-Intensity+Interval+Training+vs.+Moderate+Continuous+Exercise+%E2%80%94+Effects+on+VO%E2%82%82max%2C+Lactate+Threshold%2C+Heart+Rate+Variability%2C+and+Body+Composition+in+Sedentary+Adults | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1775741203_IJAMAAPR26V4A04015.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19484289, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19484289 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=High-Intensity+Interval+Training+vs.+Moderate+Continuous+Exercise+%E2%80%94+Effects+on+VO%E2%82%82max%2C+Lactate+Threshold%2C+Heart+Rate+Variability%2C+and+Body+Composition+in+Sedentary+Adults | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** HIIT, VO₂max, lactate threshold, heart rate variability, body composition, exercise physiology, cardiorespiratory fitness, sedentary adults, interval training, sports science **Abstract:** Physical inactivity is the fourth leading risk factor for global mortality, and the promotion of effective, time-efficient exercise modalities is a public health priority. High-intensity interval training (HIIT) has emerged as a promising alternative to traditional moderate-intensity continuous training (MICT), offering comparable or superior cardiovascular and metabolic benefits in shorter training durations. However, comparative evidence from well-powered randomised trials with comprehensive physiological outcome batteries — encompassing cardiorespiratory fitness (VO₂max), lactate threshold, cardiac autonomic function (heart rate variability), and body composition — assessed across multiple exercise modalities simultaneously is limited. This twelve-week randomised controlled trial enrolled 248 sedentary adults aged 25–55 into five training conditions: control, moderate continuous training (MCT), high-intensity continuous training (HCT), HIIT, and a combined HIIT-plus-strength training programme. HIIT produced the largest improvement in VO₂max (+12.4 mL/kg/min; p<0.001), while the combined HIIT-plus-strength condition achieved the most favourable composite outcome including VO₂max improvement (+14.4 mL/kg/min), largest lean mass gain (+3.2 kg), greatest fat mass reduction (−5.1%), and strongest heart rate variability increase (RMSSD +24.0 ms). The lactate-running speed curve analysis demonstrated an OBLA (onset of blood lactate accumulation) shift of +2.4 km/h in the HIIT group versus +0.8 km/h in the MCT group, confirming HIIT's superior effect on lactate threshold — a key determinant of endurance performance capacity. --- #### Work-Life Balance Challenges and Organizational Support for Women in the Healthcare Sector: A Study of Private and Trust Hospitals in Vadodara District **Authors:** Dr Khan Shabana Parveen, Dr Medha Wadhwa | **Affiliation:** Assistant Professor, Indian Institute of Public Health, Gandhinagar, Gujarat, India **Pages:** 104-112 | **Published:** 2026/04/21 | **DOI:** https://doi.org/10.5281/zenodo.19675869 **URL:** https://www.ijama.in/papers?paper=Work-Life+Balance+Challenges+and+Organizational+Support+for+Women+in+the+Healthcare+Sector%3A+A+Study+of+Private+and+Trust+Hospitals+in+Vadodara+District | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1776753895_IJAMAAPR26V4A04016.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19675869, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19675869 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Work-Life+Balance+Challenges+and+Organizational+Support+for+Women+in+the+Healthcare+Sector%3A+A+Study+of+Private+and+Trust+Hospitals+in+Vadodara+District | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** WLB, working women, family size, age group, marital status **Abstract:** Background: Work life Balance is an important phenomenon concerning a lot of working employees. Females form a major proportion of the works force in the healthcare industry and the policies should focus on their well-being for a stress free environment. Many of research has been carried out focusing on work life balance. However, there has been very few research concerning the work life balance of female healthcare professionals working in private and trust hospitals. Therefore, this study aims to assess the challenges and organizational support for the female healthcare professionals working in hospitals of Vadodara district (India). Methodology: The data collection tool is a structured close ended questionnaire where in the respondents were asked to choose their option pertaining to various parameters of work life balance. The data collected from 867 female healthcare professionals working in private and trust hospitals of Vadodara (India). The data collected were analyzed using SPSS version 23. The statistical test used was Kruskal-Wallis and Mann-Whitney test at 95% confidence level. Major Results: There were 304 female doctors and 563 nurses in the study. among 288 female healthcare professionals under 30, 270 had personal life expectations and workplace support, while 18 did not. Of the 161 aged 41-50, 160 had personal life expectations and support, and only 1 did not. A chi-square test confirmed a significant association between age and personal life expectations & workplace support (p < 0.05). Conclusions: Work life balance is a critical area of concern for employers within human resource area, therefore this study highlights a key issue that need to be address to enhance the satisfaction and well-being of female healthcare professionals. --- #### Yoga-Based Lifestyle Intervention versus Pharmacological Management in Metabolic Syndrome: A Randomised Controlled Trial Assessing Glycaemic Control, Lipid Profiles, Anthropometric Indices **Authors:** Priya Ramachandran, Suresh Kumar Nair, Ananya Krishnamurthy | **Affiliation:** Department of Medicine and Integrative Health Sciences, Marwar Medical University, Jodhpur **Pages:** 113-117 | **Published:** 2026/04/21 | **DOI:** https://doi.org/10.5281/zenodo.19681994 **URL:** https://www.ijama.in/papers?paper=Yoga-Based+Lifestyle+Intervention+versus+Pharmacological+Management+in+Metabolic+Syndrome%3A+A+Randomised+Controlled+Trial+Assessing+Glycaemic+Control%2C+Lipid+Profiles%2C+Anthropometric+Indices | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1776780678_IJAMAAPR26V4A04017.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19681994, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19681994 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Yoga-Based+Lifestyle+Intervention+versus+Pharmacological+Management+in+Metabolic+Syndrome%3A+A+Randomised+Controlled+Trial+Assessing+Glycaemic+Control%2C+Lipid+Profiles%2C+Anthropometric+Indices | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** metabolic syndrome, yoga intervention, glycaemic control, lipid profile, inflammatory biomarkers, urban India, randomised controlled trial, integrative medicine **Abstract:** Metabolic syndrome (MetS) affects approximately 33% of urban Indian adults and constitutes a primary driver of type 2 diabetes, cardiovascular disease, and non-alcoholic fatty liver disease in the Indian subcontinent. While pharmacological management with statins, metformin, and antihypertensives is standard of care, yoga-based lifestyle interventions have demonstrated promising preliminary effects on cardiometabolic risk factors in small uncontrolled studies. This twenty-four-week parallel-arm randomised controlled trial enrolled 312 urban adults (aged 30–60 years) with confirmed MetS by IDF criteria across three AIIMS-affiliated urban centres in Delhi-NCR. Participants were randomised to: Yoga-Based Lifestyle Intervention (YBLI, n=104), Pharmacological Management alone (PM, n=104), or Combined YBLI plus Pharmacological Management (YBLI+PM, n=104). Primary outcomes included fasting blood glucose, HbA1c, lipid panel (LDL-C, HDL-C, TG), waist circumference, and high-sensitivity C-reactive protein (hs-CRP). The YBLI+PM group achieved the greatest reductions in HbA1c (−1.8%, p<0.001), fasting glucose (−32.4 mg/dL), LDL-C (−28.6 mg/dL), and hs-CRP (−2.4 mg/L) compared to either intervention alone. YBLI alone produced clinically meaningful reductions in waist circumference (−6.2 cm) and triglycerides (−38.4 mg/dL), comparable to PM alone, suggesting yoga may serve as a safe and effective non-pharmacological alternative for early-stage MetS management. These findings support the integration of structured yoga programmes into standard MetS management protocols in Indian clinical settings --- #### Progressive Resistance Training versus Moderate-Intensity Aerobic Exercise for Glycaemic Control, Skeletal Muscle Mass, Insulin Sensitivity, and Cardiovascular Risk Reduction in Type 2 Diabetes Mellitus **Authors:** Meenakshi P., Rajesh Gopinathan, Lakshmi N. | **Affiliation:** Department of Endocrinology, Diabetology, and Exercise Medicine, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, India **Pages:** 118-122 | **Published:** 2026/04/21 | **DOI:** https://doi.org/10.5281/zenodo.19682026 **URL:** https://www.ijama.in/papers?paper=Progressive+Resistance+Training+versus+Moderate-Intensity+Aerobic+Exercise+for+Glycaemic+Control%2C+Skeletal+Muscle+Mass%2C+Insulin+Sensitivity%2C+and+Cardiovascular+Risk+Reduction+in+Type+2+Diabetes+Mellitus | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1776780845_IJAMAAPR26V4A04018.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19682026, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19682026 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Progressive+Resistance+Training+versus+Moderate-Intensity+Aerobic+Exercise+for+Glycaemic+Control%2C+Skeletal+Muscle+Mass%2C+Insulin+Sensitivity%2C+and+Cardiovascular+Risk+Reduction+in+Type+2+Diabetes+Mellitus | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** type 2 diabetes mellitus, progressive resistance training, aerobic exercise, glycaemic control, skeletal muscle mass, insulin sensitivity, GLUT4, HOMA-IR, South Asian phenotype, exercise therapy **Abstract:** Type 2 diabetes mellitus (T2DM) affects over 101 million adults in India, constituting the world's largest absolute diabetes burden, with exercise therapy representing an underutilised yet evidence-supported pillar of glycaemic management alongside pharmacological intervention. While aerobic exercise is the traditional guideline-endorsed exercise modality for T2DM, progressive resistance training (PRT) offers mechanistically distinct pathways to glycaemic improvement through skeletal muscle glucose transporter (GLUT4) upregulation, increased insulin-independent glucose disposal via skeletal muscle mass accretion, and enhanced basal metabolic rate. Comparative evidence from well-powered trials in the Indian population — who demonstrate the 'thin-fat' phenotype characterised by low muscle mass and high adiposity at moderate BMI — is lacking. This sixteen-week randomised controlled trial enrolled 280 adults with T2DM (aged 35–65 years, HbA1c 7.0–10.0%) across three JIPMER-affiliated diabetes clinics in Puducherry and Tamil Nadu, randomised to Progressive Resistance Training (PRT, n=95), Moderate-Intensity Aerobic Exercise (MIAE, n=95), or Combined PRT plus MIAE (COMB, n=90). The COMB group achieved the greatest HbA1c reduction (−1.6%, p<0.001) and combined skeletal muscle index improvement (+1.4 kg/m²) with fat mass reduction (−4.8%). PRT alone produced superior skeletal muscle mass gains (+1.8 kg lean mass) and HOMA-IR improvement (−2.4 units) compared to MIAE alone, while MIAE achieved greater VO₂max improvement (+6.8 mL/kg/min). These results challenge the aerobic-exercise primacy in T2DM guidelines and support PRT as an equally effective and potentially more appropriate exercise modality for the low muscle mass Indian diabetic phenotype. --- #### Luxury Brand Consumption, Willingness-to-Pay Premium and Consumer Segmentation in Emerging India — A 3D Surface, Donut and Confidence Ellipse Analysis **Authors:** Rupa Krishna, Arjun Gupta | **Affiliation:** Department of Marketing, Indian Institute of Management Kozhikode, Kerala, India Department of Management Studies, Delhi Technological University, New Delhi, India **Pages:** 123-125 | **Published:** 2026/02/15 | **DOI:** https://doi.org/10.5281/zenodo.19709948 **URL:** https://www.ijama.in/papers?paper=Luxury+Brand+Consumption%2C+Willingness-to-Pay+Premium+and+Consumer+Segmentation+in+Emerging+India+%E2%80%94+A+3D+Surface%2C+Donut+and+Confidence+Ellipse+Analysis | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1776952459_IJAMAAPR26V4A04019.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19709948, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.19709948 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Luxury+Brand+Consumption%2C+Willingness-to-Pay+Premium+and+Consumer+Segmentation+in+Emerging+India+%E2%80%94+A+3D+Surface%2C+Donut+and+Confidence+Ellipse+Analysis | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** luxury brands, consumer behaviour, willingness-to-pay, brand loyalty, India, aspiration, conjoint analysis, segmentation, hedonic consumption, conspicuous consumption, INSEAD **Abstract:** India's luxury market, valued at USD 8.5 billion in 2023 and projected to reach USD 22 billion by 2030 at a 14.5% CAGR, has emerged as one of the three fastest-growing luxury markets globally alongside China and Southeast Asia. The Indian luxury consumer profile is distinctive: a bimodal distribution combining India's 860,000 dollar-millionaires who exhibit consumption patterns comparable to Western luxury consumers in terms of brand sophistication and international travel exposure, and a much larger 'aspirational luxury' segment of approximately 38 million upper-middle-income households consuming entry-level luxury goods as status signalling and quality hedging against the counterfeiting risk that pervades India's unbranded apparel and accessories markets. This study examines luxury brand consumption across 2,480 respondents in metro, tier-2, and tier-3 Indian cities, employing conjoint analysis for willingness-to-pay premium estimation, a three-dimensional surface model of WTP as a joint function of income and aspiration score, and confidence ellipse consumer segmentation identifying four distinct luxury consumer segments. A donut chart reveals luxury spending category distribution, while box-whisker distributions confirm brand loyalty's significant variation across city tiers. The INSEAD collaboration contributes the luxury brand equity measurement methodology and the hedonic consumption framework distinguishing conspicuous consumption from connoisseurship motivation. WTP premium ranges from 8.4% (eco-packaging, rural) to 36.2% (green building features, metro), and four consumer segments — Affluent Brand Loyal, Aspirational Buyers, Value-Seeker Luxury, and Occasion-based — show statistically distinct price-consciousness and brand-consciousness profiles. --- #### Post-Merger Cultural Integration, Talent Retention and Synergy Realisation in Indian Corporate Mergers **Authors:** Nandita K., Praveen Y. | **Affiliation:** Department of Human Resource Management, XLRI School of Business and Human Resources, Jamshedpur, Jharkhand, India **Pages:** 126-129 | **Published:** 2026/02/15 | **DOI:** https://doi.org/10.5281/zenodo.19710042 **URL:** https://www.ijama.in/papers?paper=Post-Merger+Cultural+Integration%2C+Talent+Retention+and+Synergy+Realisation+in+Indian+Corporate+Mergers | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1776953137_IJAMAAPR26V4A04020.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19710042, https://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19710042 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Post-Merger+Cultural+Integration%2C+Talent+Retention+and+Synergy+Realisation+in+Indian+Corporate+Mergers | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** post-merger integration, cultural integration, M&A, talent retention, synergy realisation, cultural distance, India, organisational culture, GLOBE, Hofstede **Abstract:** Corporate mergers and acquisitions, while strategically justified through synergy rationale, fail to deliver expected value creation in over 50% of cases — a persistent finding in the M&A literature spanning four decades that points to post-merger integration (PMI) execution rather than pre-merger strategy as the primary value determination locus. India's accelerating M&A activity — 2,084 deals valued at USD 112 billion in FY2024, up from 1,428 deals at USD 68 billion in FY2020 — creates an urgent need for evidence on the cultural integration determinants of merger success that supplements the well-developed financial performance literature. This study examines post-merger cultural integration outcomes across 42 Indian corporate mergers consummated between 2018-2022, using a longitudinal design measuring culture fit scores, employee retention, and synergy realisation at pre-merger baseline, 6, 12, and 24 months post-merger. A waterfall chart decomposes total M&A value creation into its synergy and integration cost components, revealing that cultural friction (₹240 Cr average) and talent attrition (₹320 Cr) consume 74% of gross synergy gains (₹1,640 Cr). Violin plot distributions of culture fit scores over time confirm the characteristic integration trajectory — initial deterioration at 6 months before progressive improvement through 24 months. The regression with 95% CI confirms cultural distance as the strongest integration cost predictor (r=0.74). The WU Vienna collaboration contributes the GLOBE-based cultural distance measurement and the cross-national merger integration typology --- #### Family Business Governance, Succession Planning and Generational Performance **Authors:** Suresh Mahadeva, Kavitha Balakrishna | **Affiliation:** Thomas Schmidheiny Centre for Family Enterprise, Indian Institute of Management Ahmedabad, Gujarat, India **Pages:** 130-133 | **Published:** 2026/02/15 | **DOI:** https://doi.org/10.5281/zenodo.19710074 **URL:** https://www.ijama.in/papers?paper=Family+Business+Governance%2C+Succession+Planning+and+Generational+Performance | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1776953331_IJAMAAPR26V4A04021.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19710074, https://explore.openaire.eu/search/result?pid=10.5281/zenodo.19710074 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Family+Business+Governance%2C+Succession+Planning+and+Generational+Performance | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** family business, succession planning, corporate governance, India, generational transition, family council, BSE, SEBI, professionalisation, STEP programme, family enterprise **Abstract:** Family businesses constitute the dominant form of enterprise organisation in India, accounting for an estimated 67% of BSE-listed companies by count and 54% by market capitalisation — a proportion significantly above the global average for listed markets that reflects India's historical accumulation of family business groups (the 'house of Tata', 'house of Birla', and similar conglomerates) that survived post-Independence economic policy turbulence through family cohesion and political networking that professional management organisations could not sustain. India's family business landscape is simultaneously at a critical inflection point: the generational succession from founders or second-generation owners to third-generation inheritors — often educated at IITs, IIMs, and international universities — is occurring at the same moment that external governance pressures (SEBI's mandatory independent director requirements, institutional investor engagement, family quarrel-induced governance failures at Cyrus Mistry-Tata and ADAG group level) are forcing professionalisation. This study analyses 422 Indian family businesses — 284 BSE-listed and 138 unlisted — across sectors, examining the relationship between governance formalisation (family council, succession policy, independent board, shareholding clarity), generational stage (1st, 2nd, 3rd generation ownership), and firm performance (ROA, revenue growth, employment generation). A treemap visualises the sector distribution of family business revenue; radar charts reveal succession readiness profiles across governance dimensions; violin plot distributions confirm the 1st-generation performance premium over 2nd and 3rd generation; and a lollipop chart tracks governance reform adoption versus SEBI target levels. The University of Witten/Herdecke collaboration contributes the STEP (Successful Transgenerational Entrepreneurship Practices) programme database and the family business governance maturity framework. --- #### Digital Marketing ROI, Social Media Platform Effectiveness and Content-Platform Engagement Matrix for Indian Consumer Brands **Authors:** Preethi Nair, Aditya Venkatesh | **Affiliation:** Department of Marketing and Communication, MICA — The School of Ideas, Ahmedabad, Gujarat, India **Pages:** 134-137 | **Published:** 2026/02/17 | **DOI:** https://doi.org/10.5281/zenodo.19710116 **URL:** https://www.ijama.in/papers?paper=Digital+Marketing+ROI%2C+Social+Media+Platform+Effectiveness+and+Content-Platform+Engagement+Matrix+for+Indian+Consumer+Brands | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1776953745_IJAMAAPR26V4A04022.pdf | **Indexed in:** https://doi.org/10.5281/zenodo.19710116, http://explore.openaire.eu/search/result?pid=10.5281%2Fzenodo.19710116 **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Digital+Marketing+ROI%2C+Social+Media+Platform+Effectiveness+and+Content-Platform+Engagement+Matrix+for+Indian+Consumer+Brands | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 4, April 2026 **Keywords:** digital marketing, social media, ROI, Instagram, YouTube, content marketing, engagement rate, India, brand metrics, conversion funnel, influencer marketing, Google Ads, ROMI **Abstract:** India's digital advertising market, valued at ₹57,800 crore in FY2024 and growing at 22% annually — now accounting for 52% of total advertising spend compared to 21% in 2019 — represents the fastest structural media shift in Indian marketing history. The pandemic-accelerated adoption of digital media consumption across India's 759 million internet users, the dominance of short-video content through Instagram Reels and YouTube Shorts (India is YouTube's largest global market and Instagram's second-largest), and the maturation of performance marketing measurement infrastructure have collectively transformed digital marketing from an experimental 'test and learn' budget line to the primary customer acquisition and brand-building investment for Indian consumer brands. This study examines digital marketing ROI, content-platform engagement optimisation, and customer conversion funnel efficiency across 124 Indian consumer brand digital campaigns (FY2022-FY2024) spanning FMCG, fashion and apparel, consumer electronics, food and beverage, and personal care categories. A bubble chart maps platform spend versus ROI with monthly reach as bubble size; a stacked area chart traces digital revenue channel attribution over 24 months; a funnel chart visualises the conversion journey from awareness to purchase; a radar chart profiles brand metric improvements from digital campaigns; and a heatmap quantifies content type versus platform engagement rate interactions.

This paper introduces a comprehensive Retrieval Augmented Generation (RAG) framework that integrates multimodal large language models (MLLMs) with real-time, knowledge-grounded question answering systems. The proposed architecture — MultiRAG — combines a dense bi-encoder retrieval backbone with a cross-modal fusion module capable of jointly indexing and retrieving text, images, tables, and structured data. Retrieved multimodal evidence is processed by a vision-language model (VLM) serving as the generative backbone, conditioned on retrieved context through a novel cross-attention grounding mechanism that attenuates hallucination by enforcing faithfulness constraints at the token level. Experiments conducted on four benchmark datasets — Natural Questions, WebQA, MultiModalQA, and a custom real-time knowledge update benchmark (RKUB-2024) — demonstrate that MultiRAG achieves 87.3% Exact Match on open-domain QA, 91.4% answer faithfulness score, and 6.7× reduction in hallucination rate compared to vanilla LLM baselines. Real-time knowledge ingestion pipeline latency averages 340 ms per document, supporting continuous knowledge grounding without model fine-tuning. The system reduces hallucination by 82% over standard LLM deployment and outperforms all retrieval-augmented baselines by 4.2–9.8 percentage points across evaluation metrics --- ### Issue 5 — May 2026 — https://www.ijama.in/archives.php?volume=3&issue=5 #### Edge-AI Based Real-Time Crack Detection and Severity Classification for Concrete Bridge Inspection Using Deep Convolutional Networks **Authors:** Vikram S.

This paper presents an edge-AI inspection platform that performs real-time crack detection, segmentation and severity classification onboard an unmanned aerial vehicle. A lightweight encoder–decoder network combining a MobileNet-V3 backbone with a U-Net decoder was trained on a curated dataset of 11 240 bridge surface images and deployed on an NVIDIA Jetson Orin Nano edge device. The proposed model achieved a mean intersection-over-union of 0.86 and a sustained inference rate of 22 frames per second at 512×512 input resolution, outperforming three baseline architectures while remaining within a 7 W power envelope. Field validation across two bridge structures in Karnataka demonstrated reliable detection of hairline through severe crack categories with geo-tagged outputs streamed to a cloud dashboard for engineering review --- #### Thermal Performance Analysis of a Phase-Change-Material Enhanced Flat-Plate Solar Collector **Authors:** Suresh K.

This paper develops a one-dimensional transient analytical model for a flat-plate solar collector augmented with a paraffin-based phase-change-material (PCM, RT-44) layer beneath the absorber plate, and validates the model against an instrumented prototype tested at IIT Bombay. The governing energy balance is formulated through a coupled set of ordinary differential equations incorporating sensible and latent heat storage, with the enthalpy method used to capture the melting front. Outdoor experiments conducted over twelve clear-sky days demonstrate that the PCM-augmented collector sustains a useful outlet temperature above 50 °C for an additional 2.6 hours after sunset relative to the baseline, while raising the daily averaged thermal efficiency from 51.4 % to 62.8 %. Predicted outlet temperatures agree with measurements within ±5 % across the operating envelope, confirming the suitability of the analytical formulation for design optimisation --- #### Computer Vision-Based Real-Time Pothole Detection and Severity Assessment System for Urban Road Maintenance **Authors:** Aiman R., Aisyah B., Wei U.

Five mix designs incorporating FA at 0%, 5%, 10%, 15%, and 20% replacement levels by weight of cement were prepared and tested for compressive strength at 28, 56, and 90 days curing, flexural strength, split tensile strength, water absorption, and rapid chloride permeability (RCPT). Workability was assessed through slump cone tests and compacting factor tests. Microstructural investigation was conducted through scanning electron microscopy (SEM) imaging at 28 days. Results indicate that 10% FA replacement yields the optimum combination of strength and durability, achieving a 28-day compressive strength of 25.0 MPa, a 90-day value of 33.1 MPa, water absorption of 3.4%, and RCPT charge of 890 Coulombs. The slow pozzolanic reactivity of FA produces progressive strength gain between 56 and 90 days that partially offsets the early-strength deficit relative to the control mix. Replacement levels exceeding 15% result in measurable strength reduction at 28 days but remain within acceptable limits at 90 days for low-demand structural applications. SEM imaging confirms formation of denser calcium silicate hydrate (C-S-H) gel and reduced porosity at the interfacial transition zone (ITZ) in FA-modified mixes at 28 days. The study demonstrates that FA incorporation at optimum dosage simultaneously reduces embodied carbon by approximately 9% and improves long-term durability performance, making it suitable for sustainable concrete construction in Indian conditions. --- #### Characterisation, Antibacterial Activity and In Vitro Anticancer Evaluation **Authors:** Vikram Desai, Sonal Mehta, Fatima Naaz | **Affiliation:** Department of Biotechnology, Karpagam College of Arts and Science, Coimbatore, India Department of Biochemistry, Nirmala College for Women, Coimbatore, India **Pages:** 22-31 | **Published:** 2026/05/05 | **DOI:** https://doi.org/10.5281/zenodo.20077814 **URL:** https://www.ijama.in/papers?paper=Characterisation%2C+Antibacterial+Activity+and+In+Vitro+Anticancer+Evaluation | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1778154207_IJAMAMAY26V305A05.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Characterisation%2C+Antibacterial+Activity+and+In+Vitro+Anticancer+Evaluation | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** ZnO nanoparticles, green synthesis, Azadirachta indica, antibacterial activity, MTT assay, anticancer, ROS, zone of inhibition, MIC, XRD characterisation **Abstract:** The green synthesis of zinc oxide nanoparticles (ZnO NPs) using plant-based reducing and capping agents has gained significant scientific attention as a sustainable and low-toxicity alternative to conventional chemical and physical synthesis routes. This study reports the synthesis of ZnO NPs using aqueous leaf extract of Azadirachta indica (neem), a medicinally important plant whose phytochemical constituents — including nimbidin, azadirachtin, quercetin, and rutin — serve as natural reducing and stabilising agents during nanoparticle formation. The synthesised ZnO NPs were characterised using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), ultraviolet-visible spectroscopy (UV-Vis), and scanning electron microscopy (SEM) to confirm their crystalline structure, surface chemistry, particle size, optical properties, and morphology. XRD analysis confirmed the wurtzite hexagonal crystal structure with crystallite size of 38.4 nm (Scherrer equation), and DLS particle size distribution indicated a mean hydrodynamic diameter of 42.1 nm with polydispersity index of 0.21. Antibacterial activity was evaluated against five pathogenic organisms — Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Bacillus subtilis — by disc diffusion and minimum inhibitory concentration (MIC) assays. The highest zone of inhibition of 20.1 mm was recorded against S. aureus at 400 µg/mL. In vitro anticancer activity assessed by MTT assay against HepG2, MCF-7, and HeLa cell lines revealed IC₅₀ values of 178.4, 112.6, and 98.3 µg/mL respectively, with reactive oxygen species (ROS) generation confirmed as the primary cytotoxic mechanism. The results establish the synthesised ZnO NPs as promising multi-functional nanomaterials with both antibacterial and anticancer applications. --- #### M30 Grade Concrete Incorporating Fly Ash and Ground Granulated Blast Furnace Slag as Supplementary Cementitious Materials **Authors:** Rajesh Kumar, Sunita Devi, Mohan Shankar | **Affiliation:** Department of Civil Engineering, Rajiv Gandhi Institute of Technology, Bangalore, Karnataka, India Department of Structural Engineering, Bapuji Institute of Engineering and Technology, Davangere, Karnataka, India **Pages:** 32-38 | **Published:** 2026/05/05 | **DOI:** https://doi.org/10.5281/zenodo.20077999 **URL:** https://www.ijama.in/papers?paper=M30+Grade+Concrete+Incorporating+Fly+Ash+and+Ground+Granulated+Blast+Furnace+Slag+as+Supplementary+Cementitious+Materials | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1778154341_IJAMAMAY26V305A06.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=M30+Grade+Concrete+Incorporating+Fly+Ash+and+Ground+Granulated+Blast+Furnace+Slag+as+Supplementary+Cementitious+Materials | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** high-performance concrete, fly ash, GGBS, supplementary cementitious materials, M30 grade, compressive strength, durability, chloride permeability, SEM, EDX, carbon footprint, Karnataka **Abstract:** The increasing demand for high-performance concrete (HPC) in Indian infrastructure projects, combined with mounting regulatory pressure to reduce the carbon footprint of construction materials, has intensified research into supplementary cementitious materials (SCMs) as partial replacements for Ordinary Portland Cement (OPC). Fly Ash (FA), a by-product of coal-fired thermal power generation — of which India produces approximately 220 million tonnes annually — and Ground Granulated Blast Furnace Slag (GGBS), generated from blast furnace iron production at rates exceeding 10 million tonnes per year in India, are both established pozzolanic and latent hydraulic SCMs whose individual effects on concrete properties are extensively documented. However, ternary blends combining FA and GGBS at optimised proportions under M30 grade conditions specific to Karnataka's tropical climate and locally sourced aggregates remain underexplored. This study investigates fresh, hardened mechanical, and durability properties of M30 grade concrete incorporating FA (10%, 20%, 30% cement replacement by weight), GGBS (10%, 20% replacement), and a ternary blend (10%FA + 10%GGBS) across seven mix designs. Properties evaluated include workability (slump, compacting factor), compressive strength at 28, 56, and 90 days, flexural and split tensile strength, water absorption, chloride permeability by Rapid Chloride Permeability Test (RCPT per ASTM C1202), and SEM/EDX microstructural analysis at 28 days. Load-deflection response of reinforced concrete beams (150×200×1200 mm) and Mercury Intrusion Porosimetry (MIP) pore structure evolution at ages 3-90 days provide additional structural performance and microstructural development data. The ternary blend achieves 90-day compressive strength of 40.8 MPa (35.5% above control), chloride permeability of 640 C (51.5% reduction versus control), and CO₂ emissions of 318 kg/m³ (22% reduction). SEM analysis confirms dense interfacial transition zones and reduced calcium hydroxide crystallinity in SCM-modified specimens. The M30+20%GGBS mix achieves 90-day compressive strength of 37.6 MPa with water absorption of 2.6%, confirming GGBS's superior densification capability. The ternary blend is recommended as the optimal formulation balancing structural performance, durability, and environmental sustainability for M30 grade reinforced concrete in tropical Karnataka construction conditions. --- #### Formulation, Characterisation, and In-Vitro Evaluation of Chitosan-PEG Conjugated PLGA Nanoparticles for Targeted Curcumin Delivery in Breast Cancer Therapy **Authors:** Priya S., Venkatesh R., Deepa S. , Arun K. | **Affiliation:** Priya S., Venkatesh R., Deepa S. , Arun K.

However, its therapeutic translation is severely impeded by poor aqueous solubility (< 1 µg/mL at physiological pH), rapid metabolic degradation, and systemic bioavailability below 1% following oral administration — collectively limiting its achievable tumour-site concentration to sub-therapeutic levels. Nanoparticulate encapsulation within biodegradable polymer matrices offers a rational strategy to overcome these limitations by protecting the hydrophobic payload from premature degradation, improving colloidal dispersion, and enabling surface functionalisation for receptor-mediated tumour targeting. This study reports the formulation, physicochemical characterisation, and in-vitro evaluation of six PLGA-based nanoparticle (NP) formulations incorporating curcumin at varying chitosan (CS) coating levels (5%, 10%, 15% w/w) and polyethylene glycol (PEG) conjugation, with a ternary formulation (F6) combining 10%CS and PEG surface modification. Nanoparticles were prepared by nanoprecipitation method with characterisation encompassing drug encapsulation efficiency (EE%), dynamic light scattering (DLS) particle size and zeta potential, polydispersity index (PDI), in-vitro drug release at pH 7.4 and pH 5.0 (simulating tumour microenvironment), FTIR spectroscopy, differential scanning calorimetry (DSC), transmission electron microscopy (TEM) structural analysis, MTT cell viability assay against MCF-7 cells, and colloidal stability study over 90 days. The ternary F6 formulation achieved the highest encapsulation efficiency (84.1%), smallest mean particle size (168 nm), most negative zeta potential (-34.8 mV), and lowest IC50 against MCF-7 cells (62.6 µg/mL versus 88.4 µg/mL for plain PLGA NPs and 42.8 µg/mL for free curcumin at 24h). In-vitro release studies confirmed sustained release over 24 hours with pH-responsive enhanced release at pH 5.0, simulating tumour microenvironment conditions. Haemolysis assay confirmed biocompatibility at therapeutic concentrations (haemolysis below 5% at 1 mg/mL). The F6 ternary formulation is recommended as an optimised platform for further in-vivo evaluation in breast cancer xenograft models. --- #### The Vijayanagara Empire and the Evolution of Carnatic Classical Music: Historical, Geographical, and Cultural Intersections (14th–17th Century) **Authors:** Saraswathi Venkataraman, Gopal Krishna | **Affiliation:** Department of History and Archaeology, Rani Channamma University, Belagavi, Karnataka, India Department of Fine Arts and Musicology, Karnatak University, Dharwad, Karnataka, India **Pages:** 46-54 | **Published:** 2026/05/05 | **DOI:** https://doi.org/10.5281/zenodo.20078044 **URL:** https://www.ijama.in/papers?paper=The+Vijayanagara+Empire+and+the+Evolution+of+Carnatic+Classical+Music%3A+Historical%2C+Geographical%2C+and+Cultural+Intersections+%2814th%E2%80%9317th+Century%29 | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1778154708_IJAMAMAY26V305A08.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=The+Vijayanagara+Empire+and+the+Evolution+of+Carnatic+Classical+Music%3A+Historical%2C+Geographical%2C+and+Cultural+Intersections+%2814th%E2%80%9317th+Century%29 | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** Vijayanagara Empire, Carnatic classical music, Purandaradasa, Haridasa movement, historical geography, raga system, temple patronage, Deccan history, Krishnadevaraya, musicology, South Indian arts **Abstract:** The Vijayanagara Empire (1336–1646 CE), the last great Hindu polity of the Deccan and peninsular South India, exercised a formative and enduring influence on the cultural geography of the Indian subcontinent disproportionate to the brevity of its political ascendancy. Spanning the territorial arc from the Tungabhadra basin in present-day Karnataka to the Kaveri delta of Tamil Nadu and the coastal trading ports of the Malabar and Coromandel seaboards, the empire's political ecology created the conditions — institutional, geographical, economic, and ideological — for the consolidation and systematic codification of the Carnatic classical music tradition that remains among the most sophisticated and intellectually rigorous art-music systems in the world. This article examines, through the convergent lenses of political history, historical geography, and musicology, the mechanisms by which the Vijayanagara court and its subordinate institutional network — temples, mathas, regional Nayaka courts, and the Haridasa movement of devotional saint-composers — shaped the theoretical foundations, pedagogical infrastructure, geographic diffusion, and social ecology of Carnatic music between the fourteenth and seventeenth centuries. Drawing on epigraphic evidence (copper plate grants, stone inscriptions from Hampi, Tirupati, and Sringeri), contemporary literary sources (the Amuktamalyada of Krishnadevaraya, the Manasollasa, traveller accounts of Domingo Paes and Fernão Nunes), and musicological scholarship on surviving compositions of the Haridasa saint-composers — particularly Purandaradasa (1484–1564), Kanakadasa (c.1509–1609), Vyasatirtha (c.1460–1539), and Annamacharya (1408–1503) — this article traces the evolution of the raga-tala-sahitya (melodic mode-rhythm-text) trinity that constitutes the structural basis of Carnatic music. It argues that the Vijayanagara period was not merely a context of patronage but an active agent of musical systematisation: the empire's multilingual literary culture, its temple endowment economy, and the institutional geography of the Haridasa movement collectively produced the pedagogical framework attributed to Purandaradasa and the raga classification structures that would be formalised by Venkatamakhi in his Chaturdandiprakasika (1660) — the canonical text of the 72 Melakarta system. The article concludes with an assessment of the empire's legacy in the post-Talikota (1565) Nayaka successor courts of Thanjavur, Madurai, and Ikkeri, tracing the direct institutional and compositional lineages connecting Vijayanagara court culture to the Trinity composers of the eighteenth century. --- #### The Semiotics and Psychology of Emojis in Social Media: A Cinematic and Survey-Based Exploration **Authors:** Eshanvi N Samaga | **Affiliation:** Computer Science Engineering Student at RNS Institute of technology **Pages:** 55-59 | **Published:** 2026/05/14 | **DOI:** https://doi.org/10.5281/zenodo.20175766 **URL:** https://www.ijama.in/papers?paper=The+Semiotics+and+Psychology+of+Emojis+in+Social+Media%3A+A+Cinematic+and+Survey-Based+Exploration | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1778738618_IJAMAMAY26V305A09%281%29.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=The+Semiotics+and+Psychology+of+Emojis+in+Social+Media%3A+A+Cinematic+and+Survey-Based+Exploration | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** Semiotics Emojis ,Psychology of Emojis **Abstract:** Methodologically, this study combines qualitative and quantitative insights. A structured questionnaire was distributed digitally to various participants across a wide age range and geographic locations. Findings were triangulated with cultural representations in cinema and analyzed using basic thematic coding. The central aim is not only to understand how emojis function semiotically but also to unpack their emotional resonance and generational perception. In the age of digitized expression, emojis have become central to nonverbal communication on social media. Far from being mere embellishments, these visual symbols encapsulate emotions, intentions, and social cues. Through an interdisciplinary lens, this paper examines the role of emojis in online communication by referencing popular cultural texts such as The Emoji Movie (2017), Inside Out (2015), and Google's short film Mummy, Selfie, Dad (2023). Additionally, this study integrates survey-based insights to reveal generational attitudes and psychological associations with emoji use. The aim is to humanize the emoji phenomenon while grounding it in semiotic theory, communication psychology, and digital culture. --- #### Non-Performing Assets, Capital Adequacy, and Financial Performance of Indian Scheduled Commercial Banks **Authors:** Vinod Kumar Saxena, Ashutosh Deshpande, Fatima Begum Siddiqui | **Affiliation:** Department of Finance and Accounting, Durgadevi Institute of Management and Commerce, Varanasi, Uttar Pradesh, India Department of Commerce, Millennium College of Arts, Commerce and Management, Bhopal, Madhya Pradesh, India **Pages:** 60-66 | **Published:** 2026/05/12 | **DOI:** https://doi.org/10.5281/zenodo.20353235 **URL:** https://www.ijama.in/papers?paper=Non-Performing+Assets%2C+Capital+Adequacy%2C+and+Financial+Performance+of+Indian+Scheduled+Commercial+Banks | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779111781_IJAMAMAY26V305A10.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Non-Performing+Assets%2C+Capital+Adequacy%2C+and+Financial+Performance+of+Indian+Scheduled+Commercial+Banks | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** non-performing assets, capital adequacy, return on assets, bank profitability, IBC 2016, DEA efficiency, panel data, public sector banks, digital banking, India **Abstract:** The Indian banking sector has undergone a profound structural transformation in the period 2018–2023, shaped by the Insolvency and Bankruptcy Code (IBC) 2016 operationalisation, the Reserve Bank of India's (RBI) Asset Quality Review (AQR) and Prompt Corrective Action (PCA) framework, and the consequential large-scale resolution of stressed assets in public sector banks (PSBs). Gross Non-Performing Asset (GNPA) ratios for PSBs declined from a peak of 14.6% in 2018 to 4.8% in 2023 — a historically unprecedented balance sheet cleansing — while the introduction of Ind AS (Indian Accounting Standards) aligned provisioning norms, the recapitalisation of PSBs through ₹3.10 lakh crore in government capital infusion, and the RBI's Basel III Capital Adequacy framework implementation have collectively reshaped the capital and profitability landscape. Yet systematic longitudinal and cross-sectional analysis comparing financial performance across public sector, private sector, and foreign bank categories using panel data methods remains limited for the post-IBC period. This study analyses a balanced panel dataset of 40 Scheduled Commercial Banks (18 PSBs, 14 private sector banks, 8 foreign banks) over the six-year period 2018–2023, using pooled OLS, fixed-effects (FE), and random-effects (RE) panel regression models to examine the determinants of bank profitability (Return on Assets and Return on Equity) and technical efficiency (Data Envelopment Analysis). Variables examined include Gross NPA ratio, Capital Adequacy Ratio (CRAR), Loan-to-Deposit ratio, Operating Expense ratio, Net Interest Margin, and digital adoption index. Results confirm that GNPA ratio is the strongest negative predictor of ROA (β = −0.52) and ROE (β = −0.48), while CRAR is a significant positive predictor of both. DEA technical efficiency scores reveal that foreign banks (mean = 0.90) and private sector banks (mean = 0.84) significantly outperform PSBs (mean = 0.72). A novel finding is that digital adoption index is significantly and negatively correlated with cost-income ratio (r = −0.81, p < 0.01), providing the first multi-bank empirical evidence of digitalisation-driven operational efficiency gains in the Indian context. Policy implications for RBI's ongoing supervisory framework and the government's PSB consolidation strategy are discussed --- #### Bidirectional LSTM with Multi-Head Attention for Early Detection of Sepsis in ICU Patients Using Multivariate Time-Series Electronic Health Records **Authors:** Priya Mehta, Rajesh Kumar Sharma, Ananya Bose, Vikram Nair | **Affiliation:** Department of Computer Science and Engineering, Rajasthan Technical University, Kota, Rajasthan, India, Department of Biomedical Engineering, Uttar Pradesh Technical University, Lucknow, Uttar Pradesh, India **Pages:** 67-71 | **Published:** 2026/05/13 | **DOI:** https://doi.org/10.5281/zenodo.20353287 **URL:** https://www.ijama.in/papers?paper=Bidirectional+LSTM+with+Multi-Head+Attention+for+Early+Detection+of+Sepsis+in+ICU+Patients+Using+Multivariate+Time-Series+Electronic+Health+Records | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779170451_IJAMAMAY26V305A11.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Bidirectional+LSTM+with+Multi-Head+Attention+for+Early+Detection+of+Sepsis+in+ICU+Patients+Using+Multivariate+Time-Series+Electronic+Health+Records | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** sepsis prediction, bidirectional LSTM, multi-head attention, electronic health records, ICU, MIMIC-III, time-series classification, SHAP, early warning system **Abstract:** Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection, responsible for over 11 million deaths annually worldwide and constituting one of the most prevalent causes of ICU mortality. Early identification of sepsis from Electronic Health Records (EHRs) using machine learning approaches has attracted considerable research attention, but the inherent challenges of multivariate time-series clinical data — including irregular sampling, high missingness rates, inter-variable temporal dependencies, and clinical noise — continue to limit the translation of research models into real-world ICU deployment. This study proposes a Bidirectional Long Short-Term Memory (BiLSTM) network augmented with a multi-head attention mechanism for sepsis onset prediction from the MIMIC-III ICU dataset, using 18 clinical variables including vital signs, laboratory results, and Glasgow Coma Scale scores. The proposed architecture captures both forward and backward temporal dependencies in clinical sequences while the attention module dynamically weights clinically salient time steps. Compared to baseline models including Random Forest, SVM with radial basis function kernel, XGBoost, and standard LSTM, the proposed BiLSTM-Attention model achieves AUROC of 0.995, F1-Score of 0.981, sensitivity of 0.980, and specificity of 0.983 on the held-out test set. Ablation studies confirm the independent contributions of bidirectionality and attention. The model provides a 5.3-hour average early warning horizon before clinical sepsis criterion satisfaction, representing a clinically actionable prediction window for ICU intervention. SHAP-based feature importance analysis identifies lactate trend, heart rate variability, mean arterial pressure, and FiO₂/SpO₂ ratio as the most predictive variables, consistent with established sepsis pathophysiology. --- #### Phytochemical Profiling, Antioxidant Potential, Anticancer Activity and Antimicrobial Efficacy of Sequential Solvent Extracts of Morinda citrifolia L.

Despite ethnopharmacological documentation, rigorous phytochemical characterisation combined with systematic multifunctional biological screening of sequentially fractionated extracts from Indian-grown M. citrifolia fruit remains limited. The present study systematically evaluates the phytochemical composition, antioxidant capacity, anticancer activity against human cancer cell lines (MCF-7, A549, HepG2), and antimicrobial efficacy against Staphylococcus aureus, Escherichia coli, and Candida albicans of four sequentially prepared solvent fractions (n-hexane, chloroform, ethyl acetate, and residual ethanolic extract). Phytochemical screening identified alkaloids, flavonoids, terpenoids, saponins, and phenolic glycosides in all fractions, with the ethyl acetate fraction exhibiting the highest total phenolic content (138.4 ± 5.2 mg GAE/g) and flavonoid content (78.3 ± 4.1 mg QE/g). DPPH and ABTS radical scavenging assays confirm superior antioxidant capacity of the ethyl acetate fraction (DPPH IC₅₀: 28.6 ± 1.4 μg/mL). Anticancer MTT assays demonstrate the ethyl acetate fraction's preferential cytotoxicity toward MCF-7 cells (IC₅₀: 38.4 ± 2.1 μg/mL) with negligible toxicity toward normal Vero cells (>200 μg/mL), indicating selective antiproliferative activity. HPLC-DAD analysis identifies scopoletin, rutin, quercetin, kaempferol, and ursolic acid as major bioactive constituents. Molecular docking of the five principal compounds against EGFR tyrosine kinase (PDB: 1IVO), COX-2 (PDB: 5KIR), and dihydrofolate reductase (DHFR, PDB: 1DLS) using AutoDock Vina reveals scopoletin as the highest-affinity ligand for EGFR (ΔG = −8.4 kcal/mol), comparable to the co-crystallised erlotinib reference (ΔG = −8.9 kcal/mol). These findings provide mechanistic support for traditional uses and validate M. citrifolia ethyl acetate fraction as a candidate for further preclinical investigation as an adjunctive anticancer and anti-infective botanical drug. --- #### Fatigue Behaviour, Tribological Performance and Failure Analysis of Al-SiC Metal Matrix Composites Fabricated by Stir Casting for Automotive Structural Applications **Authors:** Rajesh Kumar Srivastava | **Affiliation:** Department of Mechanical Engineering, Bundelkhand Institute of Engineering and Technology, Jhansi, Uttar Pradesh, India **Pages:** 79-85 | **Published:** 2026/05/14 | **DOI:** https://doi.org/10.5281/zenodo.20365787 | **ISSN:** https://doi.org/10.5281/zenodo.20365787 **URL:** https://www.ijama.in/papers?paper=Fatigue+Behaviour%2C+Tribological+Performance+and+Failure+Analysis+of+Al-SiC+Metal+Matrix+Composites+Fabricated+by+Stir+Casting+for+Automotive+Structural+Applications | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779170808_IJAMAMAY26V305A13.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Fatigue+Behaviour%2C+Tribological+Performance+and+Failure+Analysis+of+Al-SiC+Metal+Matrix+Composites+Fabricated+by+Stir+Casting+for+Automotive+Structural+Applications | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** metal matrix composites, Al-SiC, stir casting, fatigue behaviour, tribology, wear resistance, SEM fractography, automotive materials, S-N curve, Al 6061 **Abstract:** Aluminium–Silicon Carbide (Al–SiC) metal matrix composites (MMCs) have attracted considerable industrial interest owing to their superior specific strength, stiffness, and wear resistance relative to unreinforced aluminium alloys, making them particularly attractive for weight-sensitive automotive structural components including suspension arms, brake rotors, and engine mounts. However, the fatigue life and tribological behaviour of Al–SiC MMCs fabricated by stir casting — a commercially scalable and cost-effective processing route — remain insufficiently characterised under multi-axial loading and elevated temperature conditions representative of in-service automotive environments. This study fabricates Al 6061 alloy reinforced with SiC particulates at 5 wt%, 10 wt%, 15 wt%, and 20 wt% via double-pass stir casting at 750°C with electromagnetic stirring and characterises the resulting composites through tensile testing, rotating-bending fatigue testing (R = –1, 10⁶ to 10⁸ cycle range), pin-on-disc tribological assessment under dry and lubricated conditions, and fractographic analysis by SEM. The effect of SiC reinforcement fraction on S–N fatigue behaviour, wear rate, coefficient of friction, and failure mode is systematically quantified. Results confirm that 15 wt% SiC addition yields the optimal fatigue endurance limit (172 MPa, 38% above unreinforced control at 10⁷ cycles) while maintaining acceptable ductility (elongation 4.2%). The 20 wt% SiC composite exhibits the lowest specific wear rate (2.4 × 10⁻⁵ mm³/N·m) under dry sliding, representing a 61% reduction versus the matrix alloy. SEM fractography reveals a transition from transgranular fatigue cracking in low-SiC composites to interfacial debonding-dominated fracture at 20 wt% SiC, with implications for optimum reinforcement content selection in fatigue-critical designs. --- #### Machine Learning-Based Predictive Fault Detection in Industrial Rotating Machinery Using Hybrid CNN-LSTM Architecture **Authors:** Rajesh Kumar Sharma, Meenakshi Devi, Suresh Chandra | **Affiliation:** Department of Mechanical Engineering, Bundelkhand Institute of Engineering and Technology, Jhansi, Uttar Pradesh, India Department of Computer Science and Engineering, Veer Bahadur Singh Purvanchal University, Jaunpur, Uttar Pradesh, India **Pages:** 86-94 | **Published:** 2026/05/14 | **DOI:** https://doi.org/10.5281/zenodo.20365850 **URL:** https://www.ijama.in/papers?paper=Machine+Learning-Based+Predictive+Fault+Detection+in+Industrial+Rotating+Machinery+Using+Hybrid+CNN-LSTM+Architecture | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779171015_IJAMAMAY26V305A14.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Machine+Learning-Based+Predictive+Fault+Detection+in+Industrial+Rotating+Machinery+Using+Hybrid+CNN-LSTM+Architecture | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** predictive maintenance, fault detection, CNN-LSTM, vibration analysis, rotating machinery, deep learning, condition monitoring, industrial IoT **Abstract:** Industrial rotating machinery such as motors, pumps, gearboxes and bearings account for a significant share of unplanned downtime losses in manufacturing and process industries globally, with annual costs exceeding USD 647 billion. Conventional rule-based condition monitoring approaches dependent on fixed vibration amplitude thresholds fail to capture the complex time-frequency interactions that characterise incipient fault signatures. This study proposes and evaluates a hybrid Convolutional Neural Network–Long Short-Term Memory (CNN-LSTM) architecture trained on raw time-domain vibration signals from a purpose-built experimental rotating machinery rig equipped with four accelerometers sampling at 25.6 kHz. The proposed model simultaneously learns spatial feature hierarchies via convolutional layers and temporal dependencies via LSTM units, eliminating the need for hand-crafted features. Five fault classes—bearing inner race defect, rotor imbalance, gear tooth wear, stator winding fault, and normal operation—are classified under variable speed (600–1800 RPM) and variable load (0–75% full load) conditions. The CNN-LSTM model achieves overall classification accuracy of 97.3%, outperforming standalone Support Vector Machine (84.1%), Random Forest (89.4%), and Artificial Neural Network (92.6%) baselines. The proposed architecture demonstrates robustness across operating speed variations and maintains above 96% accuracy at signal-to-noise ratios as low as 5 dB, confirming its suitability for deployment in industrially realistic noisy environments. --- #### Formulation, Characterisation and In Vitro/In Vivo Evaluation of PLGA-PEG and Chitosan Nanoparticles for Targeted Delivery of Doxorubicin in Breast Cancer Therapy **Authors:** Aniket Sharma, Sunita Y., Rohit Joshi | **Affiliation:** Department of Biotechnology, Maharishi Markandeshwar University, Ambala, Haryana, India **Pages:** 95-101 | **Published:** 2026/05/15 | **DOI:** https://doi.org/10.5281/zenodo.20423067 **URL:** https://www.ijama.in/papers?paper=Formulation%2C+Characterisation+and+In+Vitro%2FIn+Vivo+Evaluation+of+PLGA-PEG+and+Chitosan+Nanoparticles+for+Targeted+Delivery+of+Doxorubicin+in+Breast+Cancer+Therapy | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779171210_IJAMAMAY26V305A15.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Formulation%2C+Characterisation+and+In+Vitro%2FIn+Vivo+Evaluation+of+PLGA-PEG+and+Chitosan+Nanoparticles+for+Targeted+Delivery+of+Doxorubicin+in+Breast+Cancer+Therapy | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** nanoparticles, PLGA-PEG, chitosan, doxorubicin, breast cancer, targeted drug delivery, EPR effect, pharmacokinetics, MTT assay, Box-Behnken design **Abstract:** Breast cancer remains the most prevalent malignancy in women globally, accounting for approximately 2.3 million new diagnoses annually. Conventional chemotherapy with doxorubicin (DOX) is hampered by dose-limiting cardiotoxicity and non-specific systemic distribution, necessitating nanoparticle-based targeted delivery systems capable of prolonging circulation time and enhancing tumour accumulation through the enhanced permeability and retention (EPR) effect. Objective: To formulate, optimise, and comparatively evaluate PLGA-PEG and chitosan nanoparticle systems for sustained DOX delivery with improved therapeutic index. Methods: Nanoparticles were prepared by nanoprecipitation (PLGA-PEG) and ionic gelation (chitosan), optimised using a 3² Box-Behnken design, and characterised for size, PDI, zeta potential, and encapsulation efficiency. In vitro release was studied in PBS (pH 7.4 and pH 5.0). Cytotoxicity, cellular uptake, and apoptosis were evaluated in MCF-7 cells. Pharmacokinetic and biodistribution studies were conducted in Sprague-Dawley rats bearing xenograft tumours. Results: PLGA-PEG NPs showed mean size 142±8 nm, zeta potential −28.4±2.1 mV, encapsulation efficiency 84.2%, and sustained 72-hour release. Chitosan NPs showed size 197±11 nm, zeta potential +22.1±1.8 mV, and pH-responsive release. MTT assay IC50 for PLGA-PEG NPs (0.68 µg/mL) was significantly lower than free DOX (1.24 µg/mL). In vivo AUC for PLGA-PEG NPs was 3.8-fold greater than free drug. Conclusion: PLGA-PEG nanoparticles demonstrate superior sustained release, reduced cytotoxicity to normal cells, and significantly enhanced pharmacokinetic profile, positioning them as a clinically translatable platform for targeted breast cancer chemotherapy. --- #### Optimisation of Process Parameters in Wire Electrical Discharge Machining of Inconel 718 Superalloy Using Taguchi-Grey Relational Analysis and Response Surface Methodology **Authors:** Rajesh Kumar | **Affiliation:** Department of Mechanical Engineering, Bhilai Institute of Technology, Durg, Chhattisgarh, India **Pages:** 102-107 | **Published:** 2026/05/15 | **DOI:** https://doi.org/10.5281/zenodo.20423773 Style APA **URL:** https://www.ijama.in/papers?paper=Optimisation+of+Process+Parameters+in+Wire+Electrical+Discharge+Machining+of+Inconel+718+Superalloy+Using+Taguchi-Grey+Relational+Analysis+and+Response+Surface+Methodology | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779171415_IJAMAMAY26V305A16.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Optimisation+of+Process+Parameters+in+Wire+Electrical+Discharge+Machining+of+Inconel+718+Superalloy+Using+Taguchi-Grey+Relational+Analysis+and+Response+Surface+Methodology | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** WEDM, Inconel 718, Taguchi method, Grey Relational Analysis, Response Surface Methodology, material removal rate, surface roughness, recast layer, superalloy machining **Abstract:** Wire Electrical Discharge Machining (WEDM) is a non-conventional precision machining process that has assumed critical importance in the aerospace, defence, and energy sectors owing to its ability to machine electrically conductive hard-to-cut materials irrespective of mechanical hardness. Inconel 718, a nickel-based precipitation-hardenable superalloy exhibiting high creep resistance, excellent high-temperature mechanical properties, and superior oxidation and corrosion resistance, presents significant machinability challenges for conventional cutting tools due to its high work-hardening rate, low thermal diffusivity, and affinity for tool material at elevated cutting temperatures. This study investigates the simultaneous optimisation of four critical WEDM process parameters — pulse-on time (Ton: 105–135 µs), pulse-off time (Toff: 45–65 µs), servo voltage (SV: 20–40 V), and wire feed rate (WF: 4–8 m/min) — on three response variables: material removal rate (MRR), surface roughness (Ra), and kerf width (KW). A L27 Taguchi orthogonal array experimental design incorporating zinc-coated brass wire (0.25 mm diameter) in dielectric fluid (deionised water, conductivity 18 µS/cm) was used. Multi-response optimisation via Grey Relational Analysis (GRA) identified optimal parametric combination as Ton = 120 µs, Toff = 55 µs, SV = 30 V, WF = 6 m/min, yielding MRR of 42.6 mm³/min, Ra of 1.84 µm, and KW of 0.312 mm. ANOVA results indicate Ton as the dominant parameter (39.2% contribution to MRR; 51.4% to Ra). Response surface methodology confirmed the GRA-optimal combination through regression model validation (R² = 0.94). SEM-EDS analysis of machined surfaces reveals recast layer formation of 8–14 µm thickness and residual micro-crack density inversely correlated with servo voltage. The results provide process window guidelines for WEDM of Inconel 718 in near-net-shape turbine component manufacturing. --- #### Deep Learning-Based Intrusion Detection System for Industrial IoT Networks: A Comparative Evaluation of CNN-LSTM, Transformer, and Autoencoder Architectures on the CIC-IDS-2018 Dataset **Authors:** Anupam Borthakur, Swapnil Deshmukh | **Affiliation:** Department of Computer Science and Engineering, Assam Engineering College, Guwahati, Assam, India **Pages:** 108-112 | **Published:** 2026/05/15 | **DOI:** https://doi.org/10.5281/zenodo.20424053 **URL:** https://www.ijama.in/papers?paper=Deep+Learning-Based+Intrusion+Detection+System+for+Industrial+IoT+Networks%3A+A+Comparative+Evaluation+of+CNN-LSTM%2C+Transformer%2C+and+Autoencoder+Architectures+on+the+CIC-IDS-2018+Dataset | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779171529_IJAMAMAY26V305A17.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Deep+Learning-Based+Intrusion+Detection+System+for+Industrial+IoT+Networks%3A+A+Comparative+Evaluation+of+CNN-LSTM%2C+Transformer%2C+and+Autoencoder+Architectures+on+the+CIC-IDS-2018+Dataset | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** Industrial IoT, intrusion detection, deep learning, CNN-LSTM, Transformer, Variational Autoencoder, CIC-IDS-2018, network security, anomaly detection, SMOTE **Abstract:** The proliferation of Internet of Things (IoT) devices in industrial automation, smart manufacturing, and critical infrastructure — collectively termed Industrial IoT (IIoT) — has created an expansive and heterogeneous attack surface that traditional signature-based intrusion detection systems (IDS) are ill-equipped to defend. Machine-to-machine communication protocols (MQTT, OPC-UA, Modbus TCP), legacy supervisory control and data acquisition (SCADA) systems, and resource-constrained sensor nodes operating in deterministic real-time environments present unique cybersecurity challenges that demand anomaly-based detection approaches capable of identifying zero-day attacks and novel attack variants from network traffic patterns alone, without prior knowledge of attack signatures. This paper presents a systematic comparative evaluation of three deep learning architectures — a hybrid Convolutional Neural Network-Long Short-Term Memory (CNN-LSTM) model, a multi-head self-attention Transformer encoder, and a Variational Autoencoder (VAE) — for network intrusion detection on the CIC-IDS-2018 benchmark dataset (16 million traffic flows, 14 attack categories). After class-imbalance correction via Synthetic Minority Oversampling Technique (SMOTE), the CNN-LSTM model achieves macro-average F1-score of 0.9724, outperforming the Transformer (0.9681) and VAE (0.9512) on the held-out test set. Critically, the CNN-LSTM demonstrates superior detection of low-volume attacks (Infiltration: F1 = 0.912) that pose the greatest operational risk in IIoT environments. Inference latency analysis confirms that the CNN-LSTM and Transformer models satisfy real-time detection requirements (latency < 2 ms per flow on NVIDIA RTX 3060) while the VAE's reconstruction-based detection introduces unacceptable latency for real-time deployment. The paper concludes with a deployment architecture recommendation for edge-cloud hierarchical IDS in IIoT environments. --- #### High-Frequency Switching Performance, Thermal Analysis and Gate Driver Design for AlGaN/GaN High Electron Mobility Transistors in 600 V Power Conversion Applications **Authors:** Vikram Singh, Neha Agarwal, Sanjay Verma, Anupam Das | **Affiliation:** Department of Electrical Engineering, National Institute of Technology Patna, Bihar, India **Pages:** 113-119 | **Published:** 2026/05/16 | **DOI:** https://doi.org/10.5281/zenodo.20424113 **URL:** https://www.ijama.in/papers?paper=High-Frequency+Switching+Performance%2C+Thermal+Analysis+and+Gate+Driver+Design+for+AlGaN%2FGaN+High+Electron+Mobility+Transistors+in+600+V+Power+Conversion+Applications | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779171680_IJAMAMAY26V305A18.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=High-Frequency+Switching+Performance%2C+Thermal+Analysis+and+Gate+Driver+Design+for+AlGaN%2FGaN+High+Electron+Mobility+Transistors+in+600+V+Power+Conversion+Applications | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** GaN HEMT, AlGaN/GaN, wide-bandgap semiconductor, switching losses, power electronics, gate driver, double pulse test, EV charger, thermal management, figure-of-merit **Abstract:** Background: The escalating demand for high-efficiency power conversion in electric vehicle (EV) on-board chargers, photovoltaic inverters, and data centre power supplies has driven transition from silicon (Si) to wide-bandgap semiconductor devices. Gallium nitride (GaN) high electron mobility transistors (HEMTs) offer superior figure-of-merit compared to Si MOSFETs through higher critical electric field (3.3 MV/cm), higher electron mobility (2000 cm²/V·s), and lower on-resistance, enabling higher switching frequencies with reduced switching losses. Objective: To experimentally characterise the switching performance, thermal behaviour, and gate drive requirements of AlGaN/GaN HEMTs in a 600 V/10 A half-bridge converter topology and compare against Si MOSFET and SiC MOSFET benchmarks. Methods: Double-pulse test (DPT) circuits were designed and fabricated for switching loss characterisation at 400 V DC bus voltage. Thermal resistance was measured using structure function analysis. Gate drive optimisation was performed by varying gate resistance Rg (2.2–22 Ω) and gate voltage swing (−3V/+6V and 0V/+6V). Custom gate driver ICs (Texas Instruments LMG1020) were evaluated for propagation delay and cross-conduction prevention. Results: GaN HEMT achieved total switching loss of 18.4 µJ at 400 V, 10 A — 74% reduction versus Si MOSFET (71.2 µJ) and 52% reduction versus SiC MOSFET (38.4 µJ). Converter efficiency at 100 kHz reached 98.2% (GaN), 96.4% (SiC), and 94.1% (Si). Thermal resistance junction-to-case was 0.8°C/W for GaN-on-SiC versus 1.6°C/W for GaN-on-Si. Conclusion: AlGaN/GaN HEMTs deliver compelling switching and efficiency advantages over Si and SiC technologies at frequencies above 50 kHz, with gate drive design being the critical enabling factor for reliable high-frequency operation. --- #### Formulation and In Vitro Characterisation of Chitosan-Alginate Nanoparticles Loaded with Curcumin for Targeted Colon Cancer Drug Delivery: Effect of Polymer Ratio on Encapsulation Efficiency, Release Kinetics, and Cytotoxicity **Authors:** Deepa Nair, Subhash Tripathi, Moumita Ghosh | **Affiliation:** Department of Pharmaceutics, Amrita School of Pharmacy, Kochi, Kerala, India **Pages:** 120-124 | **Published:** 2026/05/16 | **DOI:** https://doi.org/10.5281/zenodo.20424192 **URL:** https://www.ijama.in/papers?paper=Formulation+and+In+Vitro+Characterisation+of+Chitosan-Alginate+Nanoparticles+Loaded+with+Curcumin+for+Targeted+Colon+Cancer+Drug+Delivery%3A+Effect+of+Polymer+Ratio+on+Encapsulation+Efficiency%2C+Release+Kinetics%2C+and+Cytotoxicity | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779171863_IJAMAMAY26V305A19.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Formulation+and+In+Vitro+Characterisation+of+Chitosan-Alginate+Nanoparticles+Loaded+with+Curcumin+for+Targeted+Colon+Cancer+Drug+Delivery%3A+Effect+of+Polymer+Ratio+on+Encapsulation+Efficiency%2C+Release+Kinetics%2C+and+Cytotoxicity | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** curcumin, chitosan, alginate, nanoparticles, colon cancer, drug delivery, ionic gelation, HCT-116, encapsulation efficiency, release kinetics, zeta potential **Abstract:** Curcumin (diferuloylmethane), the principal bioactive polyphenol of Curcuma longa, exhibits documented antiproliferative, anti-inflammatory, and pro-apoptotic activity across multiple cancer cell lines, yet its clinical translation is severely hampered by pharmacokinetic limitations including aqueous solubility below 11 ng/mL at physiological pH, extensive first-pass metabolism, and rapid systemic clearance yielding oral bioavailability typically below 1% in humans. Polymeric nanoparticle encapsulation using mucoadhesive polysaccharides that resist gastric and small intestinal degradation while releasing cargo in the colonic environment — exploiting colonic pH (6.5–7.4) and microbial enzyme-mediated polymer degradation — represents a promising strategy for colon-targeted curcumin delivery. This study reports the preparation, optimisation, and in vitro characterisation of chitosan-sodium alginate nanoparticles (CS-SA NPs) loaded with curcumin via ionic gelation method, investigating the effect of four chitosan:alginate polymer ratios (1:1, 1:2, 2:1, and 1:3 w/w) on encapsulation efficiency (EE%), drug loading capacity (DLC), particle size, zeta potential, polydispersity index (PDI), and in vitro release profile. Optimal formulation (CS:SA = 1:2, designated F3) achieves EE of 84.3 ± 2.1%, particle size 186 ± 12 nm, PDI 0.183, zeta potential -28.4 ± 1.8 mV, and cumulative curcumin release of 78.6% at 24 hours under simulated colonic fluid (pH 6.8, rat caecal content 2% w/v). In vitro cytotoxicity against HCT-116 colon cancer cell line confirms IC50 of 8.4 µg/mL for F3 nanoparticles versus 42.6 µg/mL for free curcumin solution — a 5.1-fold enhancement attributed to nanoparticle-mediated cellular uptake enhancement and sustained intracellular release. FTIR and DSC analysis confirm curcumin encapsulation and polymer-drug compatibility. These results support further in vivo evaluation of CS-SA nanoparticles as a colon-targeted curcumin delivery platform. --- #### Bi-Directional LSTM with Attention Mechanism for Real-Time Intrusion Detection in IoT-Enabled Smart Campus Networks: Architecture, Performance Evaluation, and Deployment Analysis **Authors:** Harpreet Singh Bhatia, Nidhi Sharma | **Affiliation:** Department of Computer Science and Engineering, Chandigarh Engineering College, Landran, Punjab, India Department of Information Technology, Guru Jambheshwar University of Science and Technology, Hisar, Haryana, India **Pages:** 125-133 | **Published:** 2026/05/18 | **DOI:** https://doi.org/10.5281/zenodo.20424411 **URL:** https://www.ijama.in/papers?paper=Bi-Directional+LSTM+with+Attention+Mechanism+for+Real-Time+Intrusion+Detection+in+IoT-Enabled+Smart+Campus+Networks%3A+Architecture%2C+Performance+Evaluation%2C+and+Deployment+Analysis | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779172081_IJAMAMAY26V305A20.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Bi-Directional+LSTM+with+Attention+Mechanism+for+Real-Time+Intrusion+Detection+in+IoT-Enabled+Smart+Campus+Networks%3A+Architecture%2C+Performance+Evaluation%2C+and+Deployment+Analysis | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** intrusion detection system, IoT security, Bidirectional LSTM, attention mechanism, deep learning, NSL-KDD, smart campus, network anomaly detection, DDoS, DoS, R2L, U2R **Abstract:** The exponential proliferation of Internet of Things (IoT) devices in academic and enterprise environments — with an estimated 18.8 billion connected devices globally as of 2024, projected to reach 40.6 billion by 2030 — has dramatically expanded the attack surface for network intrusions, malware propagation, and distributed denial-of-service (DDoS) campaigns. Conventional signature-based intrusion detection systems (IDS) are inadequate for IoT network environments characterised by heterogeneous device profiles, constrained computational resources, high packet rates, and the emergence of novel zero-day attack vectors that lack pre-defined signature patterns. Machine learning-based anomaly detection offers a path beyond signature limitations, but the temporal dependency structure of network traffic sequences — where the malicious intent of a packet may be discernible only in the context of preceding and succeeding traffic patterns — motivates the application of recurrent neural architectures capable of capturing bidirectional temporal context. This study proposes and evaluates a Bidirectional Long Short-Term Memory network augmented with a multi-head scaled dot-product attention mechanism (Bi-LSTM+Att) for intrusion detection in IoT-enabled smart campus network environments. The proposed architecture is trained and evaluated on the NSL-KDD benchmark dataset (125,973 training samples, 22,544 test samples across five traffic classes: Normal, DoS, Probe, R2L, and U2R) and validated on a custom campus IoT dataset collected from the smart building infrastructure of Chandigarh Engineering College comprising 48 heterogeneous IoT devices over a 60-day monitoring period. The proposed Bi-LSTM+Att model achieves 94.8% overall accuracy, 93.6% precision, 94.2% recall, and 93.9% F1-score on NSL-KDD — surpassing baseline LSTM (90.1%), SVM (87.3%), Random Forest (85.6%), and Naive Bayes (78.4%) under identical training and evaluation protocols. The attention mechanism provides interpretable feature attribution maps confirming that packet duration, source byte count, and protocol type are the dominant discriminative features for attack classification. Inference latency of 34 ms at 10,000 packets/second on a mid-range GPU confirms viability for real-time campus network deployment. These findings establish Bi-LSTM+Att as a practical, deployable IDS architecture for resource-aware IoT security management in Indian academic institution networks. --- #### Blockchain-Based Electronic Health Record Management Using Hyperledger Fabric and IPFS: Architecture, Security Analysis, and Performance Benchmarking **Authors:** Neha Kumar, Deepak Ranjan, Bimal Deka | **Affiliation:** Department of Electronics and Communication, Himachal Pradesh Technical University, Hamirpur, Himachal Pradesh, India Department of Computer Applications, Assam Science and Technology University, Guwahati, Assam, India **Pages:** 134-141 | **Published:** 2026/05/19 | **DOI:** https://doi.org/10.5281/zenodo.20424582 **URL:** https://www.ijama.in/papers?paper=Blockchain-Based+Electronic+Health+Record+Management+Using+Hyperledger+Fabric+and+IPFS%3A+Architecture%2C+Security+Analysis%2C+and+Performance+Benchmarking | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1779173954_IJAMAMAY26V305A21.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Blockchain-Based+Electronic+Health+Record+Management+Using+Hyperledger+Fabric+and+IPFS%3A+Architecture%2C+Security+Analysis%2C+and+Performance+Benchmarking | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 5, May 2026 **Keywords:** blockchain, electronic health records, Hyperledger Fabric, IPFS, smart contracts, attribute-based access control, healthcare data security, ABDM, permissioned blockchain, PBFT consensus **Abstract:** Electronic Health Records (EHRs) represent a critical information infrastructure in modern healthcare, yet centralised EHR systems remain vulnerable to single-point-of-failure attacks, unauthorised access, data tampering, and lack of patient-controlled consent mechanisms.

Carbon nanofibres (CNF), produced by catalytic vapour growth and characterised by graphitic core structures with diameters of 60-200 nm, offer high aspect ratios (50-1000), excellent intrinsic tensile modulus (100-500 GPa), and compatibility with standard epoxy matrix systems. Silicon carbide (SiC) micro-particles provide complementary enhancements in hardness, thermal conductivity, and moisture barrier performance. Hybrid nanocomposites combining CNF and SiC have been proposed as systems that exploit synergistic interfacial interactions to simultaneously enhance tensile, flexural, impact, and viscoelastic properties beyond what either filler achieves individually. However, systematic characterisation of the full property matrix across CNF loading levels of 0-5 wt.% and the effect of fixed-proportion SiC co-addition on storage modulus retention under hygrothermal ageing remains sparsely reported for aerospace-grade DGEBA/TETA epoxy systems. This study characterises neat epoxy, CNF/epoxy binary nanocomposites at 1-5 wt.% CNF, and a ternary hybrid (3 wt.% CNF + 2 wt.% SiC) across tensile, flexural, impact, dynamic mechanical analysis (DMA), and moisture absorption testing protocols. Optimal mechanical properties are achieved at 3 wt.% CNF: tensile strength 74.2 MPa (76.2% above neat epoxy), flexural strength 114.3 MPa (67.1% improvement), and impact energy 34.1 kJ/m² (87.4% improvement). The hybrid nanocomposite attains storage modulus of 3580 MPa at 30°C with glass transition temperature (Tg) of 138°C versus 112°C for neat epoxy, and equilibrium moisture absorption of 0.69% versus 1.41% for neat epoxy after 168-hour water immersion. --- #### The Psychology of True Crime Consumption: Deconstructing Parasocial Bonds, Morbid Curiosity, and Audience Engagement with Narratives of Crime **Authors:** Harsha Vardhan Alagari | **Affiliation:** Medical Undergraduate, Prathima Institute of Medical Sciences, Karimnagar, India **Pages:** 16-20 | **Published:** 2026/06/03 **URL:** https://www.ijama.in/papers?paper=The+Psychology+of+True+Crime+Consumption%3A+Deconstructing+Parasocial+Bonds%2C+Morbid+Curiosity%2C+and+Audience+Engagement+with+Narratives+of+Crime | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1780506935_IJAMAJUN26V306A03.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=The+Psychology+of+True+Crime+Consumption%3A+Deconstructing+Parasocial+Bonds%2C+Morbid+Curiosity%2C+and+Audience+Engagement+with+Narratives+of+Crime | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** parasocial interaction, true crime, morbid curiosity, terror management theory, uses and gratifications, serial killer, media psychology **Abstract:** The global proliferation of true crime media across several forms such as podcasts, docuseries, movies, literature, and social media has prompted academic interest in the behavioral, psychological, and sociological motivations of its consumers. This paper argues that such engagement is rooted in well-established psychological mechanisms rather than mere fascination or deviant tendencies, as a considerable amount of research frequently stigmatizes this behavior as a pathological condition. Integrating Parasocial Interaction Theory [1], Morbid Curiosity [2], Terror Management Theory [3], and Uses and Gratifications Theory [4], this theoretical analysis deconstructs how audiences cultivate quasi-intimate relationships with offenders, process existential dread, and eventually derive entertainment utility from true crime media. Ultimately, these findings demonstrate parasocial bonding that mirrors celebrity veneration and how it is mediated via narrative proximity, glorification of offenders, and media framing. The insights carry implications for media psychology, public health communication, and ethical responsibilities of entertainment production. --- #### Integrating Artificial Intelligence in Higher Education in India: Policy Considerations for Making Education More Integrated **Authors:** Rachana Pandey, Abhishek Mishra, Ratna Shanker Mishra | **Affiliation:** Assistant Professor of English, Vasanta College for Women, Varanasi, Uttar Pradesh, India , Assistant Professor, Department of Business Administration (Human Resource), The University of Burdwan, Purba Bardhaman, West Bengal, India , Associate Professor Office Management & Secretarial Techniques, Faculty of Arts, Banaras Hindu University Varanasi, Uttar Pradesh, India **Pages:** 21-30 | **Published:** 2026/06/06 **URL:** https://www.ijama.in/papers?paper=Integrating+Artificial+Intelligence+in+Higher+Education+in+India%3A+Policy+Considerations+for+Making+Education+More+Integrated | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781002483_IJAMAJUN26V306A04.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Integrating+Artificial+Intelligence+in+Higher+Education+in+India%3A+Policy+Considerations+for+Making+Education+More+Integrated | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** Artificial intelligence, higher education, innovation, inclusivity, diversity, equity. **Abstract:** Recent developments in the field of technology are transforming the higher education landscape of India in a massive way.

Global surface temperatures have risen by approximately 1.2°C above pre-industrial levels, driving increasingly frequent and severe weather events, rising sea levels, and profound disruptions to ecosystems worldwide. Yet the same era has witnessed an extraordinary transformation in the global energy landscape: the rapid, cost-driven ascent of renewable energy technologies—particularly solar photovoltaics and wind power—that now represent the cheapest sources of electricity ever developed. This article examines the scientific evidence underpinning climate change, analyses the growth trajectory of renewable energy, and explores the policy, economic, and technological pathways through which a transition to a net-zero global economy may be achieved. --- #### Deep Learning-Based Diabetic Retinopathy Detection Using Convolutional Neural Networks **Authors:** Vikram Singh Chauhan | **Affiliation:** Department of Computer Science and Engineering, Rajasthan Institute of Technology, Jaipur, Rajasthan, India **Pages:** 42-48 | **Published:** 2026/06/12 **URL:** https://www.ijama.in/papers?paper=Deep+Learning-Based+Diabetic+Retinopathy+Detection+Using+Convolutional+Neural+Networks | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781423608_IJAMAJUN26V306A07.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Deep+Learning-Based+Diabetic+Retinopathy+Detection+Using+Convolutional+Neural+Networks | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** diabetic retinopathy, deep learning, convolutional neural network, transfer learning, retinal fundus image, CLAHE, Grad-CAM, APTOS-2019, medical image classification **Abstract:** Diabetic Retinopathy (DR) is a leading cause of preventable blindness worldwide, affecting approximately 463 million people with diabetes globally, of whom an estimated 77.2 million reside in India. Early automated detection of DR from digital fundus photographs using deep learning methods offers a scalable, cost-effective solution for mass screening programmes in resource-constrained settings. This study presents a comparative evaluation of five convolutional neural network (CNN) architectures — VGG-16, ResNet-50, InceptionV3, DenseNet-121, and a custom-designed lightweight CNN — for four-class DR severity grading (No DR, Mild, Moderate, Severe/Proliferative) on the publicly available APTOS-2019 retinal fundus image dataset (3,662 images). All models were fine-tuned using transfer learning with ImageNet pretrained weights. Preprocessing steps including contrast-limited adaptive histogram equalization (CLAHE), green channel extraction, circular cropping, and data augmentation were applied uniformly. The proposed lightweight CNN achieves 95.3% accuracy, 94.1% precision, 94.7% recall, and 94.4% F1-score on the held-out test set, outperforming all benchmark architectures. Gradient-weighted Class Activation Mapping (Grad-CAM) visualizations confirm the model's attention to clinically relevant regions including microaneurysms, haemorrhages, and hard exudates. The model attains a mean AUC of 0.977 across all four classes. These results demonstrate that the proposed lightweight architecture, with 6.2 million parameters versus ResNet-50's 25.6 million, achieves superior diagnostic accuracy with substantially reduced computational overhead, making it suitable for deployment on mobile screening devices. --- #### Deep Learning-Based ECG Signal Classification for Automated Cardiac Arrhythmia Detection **Authors:** Rajesh Kumar Anil Kumar Tiwari | **Affiliation:** Department of Biomedical Engineering, Maulana Azad National Institute of Technology, Bhopal, Madhya Pradesh, India Department of Electronics and Communication Engineering, National Institute of Technology, Rourkela, Odisha, India **Pages:** 49-59 | **Published:** 2026/06/14 **URL:** https://www.ijama.in/papers?paper=Deep+Learning-Based+ECG+Signal+Classification+for+Automated+Cardiac+Arrhythmia+Detection | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781423913_IJAMAJUN26V306A08.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Deep+Learning-Based+ECG+Signal+Classification+for+Automated+Cardiac+Arrhythmia+Detection | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** ECG classification, cardiac arrhythmia, deep learning, convolutional neural network, bidirectional LSTM, attention mechanism, 12-lead ECG, automated diagnosis, PhysioNet, signal processing **Abstract:** Cardiac arrhythmias represent a leading cause of sudden cardiac death worldwide, affecting approximately 300,000 individuals annually in India alone. Conventional manual interpretation of 12-lead electrocardiogram (ECG) signals demands considerable clinical expertise and is susceptible to inter-observer variability, motivating the development of automated classification systems capable of consistent, rapid analysis across diverse patient populations and healthcare settings. This study presents a novel hybrid deep learning architecture combining one-dimensional convolutional neural networks (1D-CNN) and bidirectional long short-term memory (BiLSTM) networks for automated multi-class arrhythmia classification from 12-lead ECG recordings. The proposed framework incorporates a multi-scale feature extraction module, an attention mechanism for lead-specific saliency weighting, and a cascaded classification head optimised for class imbalance. The model was trained and validated on a composite dataset of 27,367 annotated 12-lead ECG recordings drawn from the PhysioNet Computing in Cardiology Challenge 2020 database, covering seven clinically significant rhythm classes: normal sinus rhythm, atrial fibrillation, ventricular tachycardia, left bundle branch block, right bundle branch block, premature atrial contraction, and ST-elevation myocardial infarction. The proposed CNN-BiLSTM model achieves an overall accuracy of 98.1%, sensitivity of 97.6%, specificity of 98.5%, F1-score of 0.979, and AUC-ROC of 0.995 on the held-out test set — substantially outperforming conventional support vector machine (87.3%), random forest (89.6%), standalone 1D-CNN (93.2%), and BiLSTM (94.7%) baselines. Ablation studies confirm the independent contributions of the attention mechanism (+1.8% accuracy) and multi-lead fusion (+1.4% accuracy). The framework demonstrates robust generalisation across age groups, gender, and signal quality categories, with mean inference time of 1.2 seconds per recording on standard hardware — clinically suitable for point-of-care screening applications. --- #### IoT-Enabled Smart Agriculture System with Machine Learning-Based Precision Irrigation and Crop Yield Prediction for Semi-Arid Farming Regions **Authors:** Sneha Patil, Gurpreet Singh Bhatia, Subhashree Mohapatra | **Affiliation:** Department of Electronics Engineering, Pune Institute of Engineering and Technology, Pune, Maharashtra, India Department of Agricultural Engineering, Punjab Agricultural Technology College, Ludhiana, Punjab, India Department of Computer Science and Engineering, Bhubaneswar Institute of Technology, Bhubaneswar, Odisha, India **Pages:** 60-66 | **Published:** 2026/06/13 **URL:** https://www.ijama.in/papers?paper=IoT-Enabled+Smart+Agriculture+System+with+Machine+Learning-Based+Precision+Irrigation+and+Crop+Yield+Prediction+for+Semi-Arid+Farming+Regions | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781424306_IJAMAJUN26V306A09.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=IoT-Enabled+Smart+Agriculture+System+with+Machine+Learning-Based+Precision+Irrigation+and+Crop+Yield+Prediction+for+Semi-Arid+Farming+Regions | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** Internet of Things, precision agriculture, smart irrigation, random forest, soil moisture, edge computing, ZigBee, Raspberry Pi, crop yield prediction, semi-arid farming **Abstract:** Agriculture contributes approximately 17–18% of India's GDP and employs over 58% of the workforce, yet remains highly vulnerable to climate variability, inefficient water use, and delayed pest and nutrient interventions due to limited access to real-time field monitoring. Precision agriculture driven by Internet of Things (IoT) sensor networks and machine learning analytics offers a scalable pathway to address these challenges, but adoption in smallholder semi-arid farming contexts in states such as Maharashtra and Rajasthan has been limited by system cost, power constraints, and connectivity. This paper presents the design, implementation, and field validation of a low-cost IoT-based smart agriculture system deployed across 12 field plots (0.5 hectare each) in Solapur district, Maharashtra. The system integrates soil moisture sensors (capacitive, ±2% accuracy), DHT22 temperature-humidity sensors, NPK electrochemical sensors, and LDR light intensity sensors connected via ZigBee mesh network to a Raspberry Pi 4 edge gateway. A Random Forest regression model trained on 60 days of multi-parameter sensor data achieves R² = 0.94 for irrigation volume prediction, reducing water consumption by 38% versus traditional flood irrigation while improving crop yield across five crop types (rice, wheat, maize, soybean, groundnut) by an average of 31.4%. System end-to-end latency for edge-processed irrigation decisions averages 12.3 ms at the 50th percentile versus 41.7 ms for cloud-only processing, confirming the edge architecture's suitability for real-time actuator control. Total hardware cost per plot is estimated at INR 8,400, with a projected payback period of 1.8 cropping seasons based on observed yield improvement and water cost savings. --- #### Smart Agriculture in Arid Regions: IoT Sensor Networks and ML for Optimal Water Management **Authors:** Nitin Kamat, Roopa Rai | **Affiliation:** Department of Agricultural Engineering, Punjab Agricultural Technology College, Ludhiana, Punjab, India **Pages:** 67-73 | **Published:** 2026/06/13 **URL:** https://www.ijama.in/papers?paper=Smart+Agriculture+in+Arid+Regions%3A+IoT+Sensor+Networks+and+ML+for+Optimal+Water+Management | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781425357_IJAMAJUN26V306A10.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Smart+Agriculture+in+Arid+Regions%3A+IoT+Sensor+Networks+and+ML+for+Optimal+Water+Management | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** Precision agriculture, Smart irrigation scheduling, Multi-crop yield prediction, Semi-arid farming, NPK electrochemical sensors, Water resource management, Climate-vulnerable agriculture, Soil volumetric water content **Abstract:** Smallholder farming in semi-arid regions like Maharashtra and Rajasthan is highly vulnerable to climate variability, inefficient water use, and delayed pest and nutrient interventions due to limited access to real-time field monitoring.

Kenaf (Hibiscus cannabinus L.), a bast fibre crop cultivated extensively in Maharashtra, Gujarat, and Rajasthan, produces fibres with specific tensile strength approaching 60–70% of E-glass’s at one-half the density, making kenaf/epoxy composites theoretically competitive with glass-fibre laminates on a specific property basis. However, the inherently hydrophilic nature of kenaf cellulose—arising from abundant hydroxyl groups on the fibre surface—results in poor fibre-matrix interfacial adhesion in hydrophobic epoxy systems and significant moisture uptake that degrades mechanical properties under humid service conditions. This study evaluates the effectiveness of two surface treatment protocols—sodium hydroxide (NaOH, 5 wt%, 2 h alkali treatment) and 3-aminopropyltriethoxysilane (silane, 1 wt% aqueous solution)—in improving the mechanical, hygroscopic, and thermomechanical performance of short kenaf fibre/epoxy composites at 5, 10, 15, 20, 25, and 30 wt% fibre loadings. Flexural strength, Young’s modulus, Charpy impact strength, water absorption (Fickian diffusion analysis over 28 days), TGA, and DMA are characterised for all combinations. The silane-treated 20 wt% composite achieves optimal performance: flexural strength of 89 MPa (112% improvement over pure epoxy), Young’s modulus of 5.6 GPa, impact strength of 66 kJ/m², and 28-day water absorption of 1.06%—substantially reduced from 1.41% for the untreated equivalent. FTIR and SEM analysis confirm that both treatments successfully remove hemicellulose and surface wax, increasing surface roughness and hydroxyl-group reactivity, with silane coupling producing additional covalent Si-O-C bonds at the fibre-matrix interface. --- #### Phytochemical Profiling, Antioxidant Potential, Anticancer Activity and Antimicrobial Efficacy of Sequential Solvent Extracts of Morinda citrifolia **Authors:** Sushma Rani, Ashok Kumar, Nidhi Srivastava, Mahesh Chandra, Reena Kumari | **Affiliation:** Department of Pharmaceutical Sciences, Babasaheb Bhimrao Ambedkar University, Lucknow, Uttar Pradesh, India Department of Biochemistry and Molecular Biology, Guru Ghasidas Vishwavidyalaya, Bilaspur, Chhattisgarh, India **Pages:** 82-89 | **Published:** 2026/06/13 **URL:** https://www.ijama.in/papers?paper=Phytochemical+Profiling%2C+Antioxidant+Potential%2C+Anticancer+Activity+and+Antimicrobial+Efficacy+of+Sequential+Solvent+Extracts+of+Morinda+citrifolia | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781504662_IJAMAJUN26V306A12.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Phytochemical+Profiling%2C+Antioxidant+Potential%2C+Anticancer+Activity+and+Antimicrobial+Efficacy+of+Sequential+Solvent+Extracts+of+Morinda+citrifolia | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** Morinda citrifolia, noni fruit, phytochemical screening, DPPH, antioxidant, anticancer, MTT assay, molecular docking, scopoletin, EGFR, antimicrobial, MIC, HPLC-DAD **Abstract:** Morinda citrifolia L. (Noni), a tropical fruit belonging to the family Rubiaceae, has been employed for over two millennia in traditional medicinal systems across Southeast Asia, the Pacific Islands, and the Indian subcontinent for the management of pain, inflammation, infections, and malignancies. Despite ethnopharmacological documentation, rigorous phytochemical characterisation combined with systematic multifunctional biological screening of sequentially fractionated extracts from Indian-grown M. citrifolia fruit remains limited. The present study systematically evaluates the phytochemical composition, antioxidant capacity, anticancer activity against human cancer cell lines (MCF-7, A549, HepG2), and antimicrobial efficacy against Staphylococcus aureus, Escherichia coli, and Candida albicans of four sequentially prepared solvent fractions (n-hexane, chloroform, ethyl acetate, and residual ethanolic extract). Phytochemical screening identified alkaloids, flavonoids, terpenoids, saponins, and phenolic glycosides in all fractions, with the ethyl acetate fraction exhibiting the highest total phenolic content (138.4 ± 5.2 mg GAE/g) and flavonoid content (78.3 ± 4.1 mg QE/g). DPPH and ABTS radical scavenging assays confirm superior antioxidant capacity of the ethyl acetate fraction (DPPH IC₅₀: 28.6 ± 1.4 μg/mL). Anticancer MTT assays demonstrate the ethyl acetate fraction's preferential cytotoxicity toward MCF-7 cells (IC₅₀: 38.4 ± 2.1 μg/mL) with negligible toxicity toward normal Vero cells (>200 μg/mL), indicating selective antiproliferative activity. HPLC-DAD analysis identifies scopoletin, rutin, quercetin, kaempferol, and ursolic acid as major bioactive constituents. Molecular docking of the five principal compounds against EGFR tyrosine kinase (PDB: 1IVO), COX-2 (PDB: 5KIR), and dihydrofolate reductase (DHFR, PDB: 1DLS) using AutoDock Vina reveals scopoletin as the highest-affinity ligand for EGFR (ΔG = −8.4 kcal/mol), comparable to the co-crystallised erlotinib reference (ΔG = −8.9 kcal/mol). These findings provide mechanistic support for traditional uses and validate M. citrifolia ethyl acetate fraction as a candidate for further preclinical investigation as an adjunctive anticancer and anti-infective botanical drug. --- #### Thermal Performance Enhancement of Shell-and-Tube Heat Exchangers Using Al₂O₃–Water Nanofluids: Experimental Investigation, CFD Validation and Multi-Objective Optimisation of Baffle Configuration **Authors:** Vikram Nath Tiwari, Sunita Devi Chauhan, Deepak Ranjan Mohanty | **Affiliation:** Department of Mechanical Engineering, Maharishi Markandeshwar University, Ambala, Haryana, India Department of Chemical Engineering, Veer Surendra Sai University of Technology, Burla, Odisha, India Department of Mechanical Engineering, Rajasthan Institute of Engineering and Technology, Jaipur, Rajasthan, India **Pages:** 89-96 | **Published:** 2026/06/13 **URL:** https://www.ijama.in/papers?paper=Thermal+Performance+Enhancement+of+Shell-and-Tube+Heat+Exchangers+Using+Al%E2%82%82O%E2%82%83%E2%80%93Water+Nanofluids%3A+Experimental+Investigation%2C+CFD+Validation+and+Multi-Objective+Optimisation+of+Baffle+Configuration | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781504867_IJAMAJUN26V306A13.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Thermal+Performance+Enhancement+of+Shell-and-Tube+Heat+Exchangers+Using+Al%E2%82%82O%E2%82%83%E2%80%93Water+Nanofluids%3A+Experimental+Investigation%2C+CFD+Validation+and+Multi-Objective+Optimisation+of+Baffle+Configuration | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** shell-and-tube heat exchanger, Al₂O₃ nanofluid, thermal performance, baffle configuration, CFD, response surface methodology, Nusselt number, pressure drop, thermal performance factor **Abstract:** Shell-and-tube heat exchangers (STHEs) account for approximately 35–40% of all heat transfer equipment installed in process industries globally, making incremental improvements in their thermal-hydraulic performance economically significant at scale. Conventional water-based working fluids exhibit limited thermal conductivity (0.60 W/m·K at 25°C), motivating research into nanofluids — colloidal suspensions of nanometre-scale metal or metal oxide particles — as drop-in thermal performance enhancement agents. Aluminium oxide (Al₂O₃) nanofluids have emerged as particularly promising owing to their relatively high thermal conductivity enhancement per unit particle volume fraction, chemical stability, and low cost relative to noble-metal and carbon-based nanomaterials. However, the combined effect of nanofluid concentration, baffle spacing, baffle cut ratio, and tube-side Reynolds number on overall heat transfer coefficient and pressure drop penalty in industrial STHEs has not been comprehensively optimised under conditions representative of North Indian chemical process plant operating temperatures. This study experimentally characterises Al₂O₃–water nanofluids at volume fractions of 0.1%, 0.5%, 1.0%, and 1.5% in a custom-fabricated single-pass STHE (shell diameter 150 mm, 19 tubes, 1500 mm tube length) with segmental baffles at three spacing levels (25%, 35%, and 45% of shell diameter) and two baffle cut ratios (20% and 25%). Overall heat transfer coefficients (U), Nusselt numbers (Nu), pressure drop (ΔP), and thermal performance factor (η) are measured across shell-side Reynolds numbers of 5,000–25,000. A validated CFD model (ANSYS Fluent 2023 R1, realizable k–ε turbulence model, mixture-phase nanofluid approach) is developed and used to extend the parametric space beyond the experimental matrix. Response surface methodology (RSM) with a central composite design (CCD) is applied to optimise the four-dimensional design space, yielding a Pareto front of optimal baffle configurations that maximise thermal performance factor subject to pressure drop constraints. The 1.0% Al₂O₃ nanofluid with 35% baffle spacing and 20% baffle cut achieves the maximum overall heat transfer coefficient of 2,847 W/m²·K — a 34.2% enhancement over base-fluid water at equivalent operating conditions — with a thermal performance factor of 1.28, confirming that the thermal gain exceeds the pumping power penalty. --- #### Quantum Computing The Next Technological Frontier and Its Impact on Science, Security, and Society **Authors:** Lalika Singh | **Affiliation:** Centre for Quantum Technologies **Pages:** 97-104 | **Published:** 2026/06/14 **URL:** https://www.ijama.in/papers?paper=Quantum+Computing+The+Next+Technological+Frontier+and+Its+Impact+on+Science%2C+Security%2C+and+Society | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781505148_IJAMAJUN26V306A14.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Quantum+Computing+The+Next+Technological+Frontier+and+Its+Impact+on+Science%2C+Security%2C+and+Society | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** Quantum computing **Abstract:** Quantum computing represents one of the most profound technological transitions in human history — a shift from the binary logic of classical computation to the probabilistic, superposition-driven mechanics of quantum physics. Where a classical bit must be either 0 or 1, a qubit can exist in both states simultaneously, and entangled qubits can encode exponentially more information than their classical equivalents. After decades of theoretical promise, quantum hardware has entered a phase of rapid, measurable progress: qubit counts are doubling annually, error rates are falling toward fault-tolerance thresholds, and the first demonstrations of "quantum advantage" — the ability of quantum systems to outperform the best classical supercomputers on specific tasks — have been achieved. This article provides a comprehensive overview of quantum computing principles, hardware modalities, applications across industry and science, global investment dynamics, and the profound implications for cryptography and national security. --- #### Caste, Class, and Intergenerational Mobility in Contemporary Urban India: Structural Persistence and Emerging Fissures **Authors:** Ananya Krishnaswamy, Rohan Shetty | **Affiliation:** Department of Sociology, University of Hyderabad, Hyderabad, India Centre for the Study of Social Systems, Jawaharlal Nehru University, New Delhi, India **Pages:** 105-111 | **Published:** 2026/06/14 **URL:** https://www.ijama.in/papers?paper=Caste%2C+Class%2C+and+Intergenerational+Mobility+in+Contemporary+Urban+India%3A+Structural+Persistence+and+Emerging+Fissures | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781510569_IJAMAJUN26V306A15.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Caste%2C+Class%2C+and+Intergenerational+Mobility+in+Contemporary+Urban+India%3A+Structural+Persistence+and+Emerging+Fissures | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** caste, social mobility, intergenerational mobility, class formation, urban India, Ambedkar, reservations policy, occupational prestige, structural equation modelling, life history **Abstract:** The relationship between caste-based social stratification and class formation in post-liberalisation urban India remains a contested terrain within Indian sociology, where structuralist accounts emphasising the enduring ascriptive force of caste compete with neo-Weberian arguments foregrounding market-driven class realignment and empirical accounts of rising intergenerational mobility among Scheduled Caste and Other Backward Class populations facilitated by reservations policy and urban migration. This study addresses the gap between these positions through a longitudinal panel analysis of intergenerational occupational and educational mobility across four caste social groups — Scheduled Castes (SC), Scheduled Tribes (ST), Other Backward Classes (OBC), and General Category — in six Indian cities (Mumbai, Delhi, Chennai, Pune, Lucknow, and Ahmedabad) over three generations. Drawing on a primary panel dataset of 3,640 household triads (grandparent-parent-adult child), supplemented by occupational prestige scoring using the Standard International Occupational Prestige Scale adapted for the Indian labour market, and qualitative life history interviews (n = 80), the study tests three competing theoretical models: Ambedkarian structural persistence, Srinivas’s Sanskritisation-mobility synthesis, and the post-liberalisation market-opening thesis. Structural equation models confirm that caste retains a significant independent effect on occupational attainment net of parental education and income (β = 0.28, p < 0.001 for SC versus General comparison), but that this effect has diminished monotonically across birth cohorts from 1950–1999. The private sector technology cluster shows the fastest convergence; the public sector shows the slowest despite reservations mandates. Life history interviews identify ‘caste micro-aggressions in the workplace’ and ‘caste-network exclusion from informal labour markets’ as mechanisms sustaining structural disadvantage even among upwardly mobile SC and ST individuals with equivalent formal credentials. --- #### Digital Inequality, Social Capital, and Mental Health Outcomes Among Urban Youth in Post-Pandemic India: A Multi-City Sociological Analysis **Authors:** Priya Ramachandran | **Affiliation:** Department of Sociology, Jawaharlal Nehru University, New Delhi, India **Pages:** 112-117 | **Published:** 2026/06/14 **URL:** https://www.ijama.in/papers?paper=Digital+Inequality%2C+Social+Capital%2C+and+Mental+Health+Outcomes+Among+Urban+Youth+in+Post-Pandemic+India%3A+A+Multi-City+Sociological+Analysis | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781511167_IJAMAJUN26V306A16.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Digital+Inequality%2C+Social+Capital%2C+and+Mental+Health+Outcomes+Among+Urban+Youth+in+Post-Pandemic+India%3A+A+Multi-City+Sociological+Analysis | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** digital inequality, social capital, mental health, urban youth, India, post-pandemic sociology, Bourdieu, structural equation modelling, PHQ-9, digital access **Abstract:** The COVID-19 pandemic precipitated an unprecedented rupture in the social fabric of urban Indian youth, simultaneously accelerating digital penetration and intensifying pre-existing structural inequalities in access to digital infrastructure, thereby creating a bifurcated landscape of social participation with divergent mental health consequences. Drawing on Bourdieu’s theory of capital conversion and Putnam’s conceptualisation of bonding and bridging social capital, this study investigates the mediating role of digital social capital in the relationship between internet access quality and psychological wellbeing among youth aged 18–30 across Mumbai, Delhi, Bengaluru, Hyderabad, and Kolkata. A mixed-methods design integrates a stratified survey (n = 2,840), twelve focus group discussions (n = 96 participants), and fourteen in-depth interviews with institutional informants including social workers, mental health professionals, and community leaders. Survey instruments incorporate the Patient Health Questionnaire-9 (PHQ-9), the Generalised Anxiety Disorder Scale-7 (GAD-7), the Online Social Capital Scale (OSCS), and a purpose-built Digital Access Quality Index (DAQI). Structural equation modelling reveals that digital social capital fully mediates the effect of DAQI on PHQ-9 scores (β = −0.34, p < 0.001), with the indirect path accounting for 67% of total effect variance. Youth in the lowest DAQI quartile report PHQ-9 scores averaging 11.4 (moderate depression range) versus 5.8 in the highest quartile — a clinically meaningful 97% differential. Bridging social capital demonstrates stronger protective effects than bonding capital on anxiety outcomes, reversing the pattern observed in pre-pandemic offline social capital research. Qualitative findings reveal three emergent mechanisms: ‘digital displacement’ of offline social ties without equivalent capital conversion, ‘platform-induced comparison strain’ intensified by algorithm-driven content curation, and ‘connectivity precarity’ as a chronic stressor distinct from acute access deprivation. Policy implications address differential infrastructure investment, school-based digital social capital curricula, and integrated mental health screening in community digital access programmes. --- #### Hybrid CNN-BiLSTM with Attention Mechanism for Short-Term Solar Photovoltaic Power Forecasting: A Multi-Feature Deep Learning Approach for Grid Integration in India **Authors:** Arjun Verma, Pallabi Ghosh | **Affiliation:** Department of Electrical Engineering, Rajasthan Technical University, Kota, Rajasthan, India Department of Electronics and Electrical Engineering, Jalpaiguri Government Engineering College, Jalpaiguri, West Bengal, India **Pages:** 117-124 | **Published:** 2026/06/14 **URL:** https://www.ijama.in/papers?paper=Hybrid+CNN-BiLSTM+with+Attention+Mechanism+for+Short-Term+Solar+Photovoltaic+Power+Forecasting%3A+A+Multi-Feature+Deep+Learning+Approach+for+Grid+Integration+in+India | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781511327_IJAMAJUN26V306A17.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Hybrid+CNN-BiLSTM+with+Attention+Mechanism+for+Short-Term+Solar+Photovoltaic+Power+Forecasting%3A+A+Multi-Feature+Deep+Learning+Approach+for+Grid+Integration+in+India | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** solar PV forecasting, deep learning, CNN, BiLSTM, attention mechanism, renewable energy, short-term forecasting, Rajasthan, grid integration, MAPE **Abstract:** Accurate short-term solar photovoltaic (PV) power forecasting is a prerequisite for safe and economically efficient integration of large-scale solar generation into national electricity grids. India's solar installed capacity reached 73.3 GW in March 2024, representing 18.4% of total installed generation capacity, with the National Solar Mission targeting 500 GW of renewable capacity by 2030 — a scale at which forecasting errors impose measurable ancillary service costs and grid stability risks. Existing forecasting models based on statistical methods (ARIMA), machine learning (SVR, MLP), or single-architecture deep learning (LSTM, CNN) fail to simultaneously capture the multi-scale temporal patterns and spatial feature correlations embedded in multi-variate meteorological and operational input data. This paper proposes a hybrid Convolutional Neural Network — Bidirectional Long Short-Term Memory (CNN-BiLSTM) model with an additive attention mechanism for 24-hour-ahead solar PV power forecasting using a 12-variable feature set including solar irradiance, ambient temperature, panel temperature, cloud cover fraction, aerosol optical depth, wind speed, humidity, precipitation, atmospheric pressure, dew point, hour-of-day, and day-of-year. The model is trained and evaluated on two years of hourly data (2021–2023) from a 5.5 MW ground-mounted PV plant in Jodhpur, Rajasthan — a high-irradiance semi-arid location representative of Rajasthan's dominant role in India's solar generation portfolio. The proposed model achieves RMSE of 0.143 MW, MAE of 0.109 MW, and MAPE of 3.7% on the held-out test set, outperforming ARIMA (MAPE 12.4%), SVR (8.9%), MLP (7.6%), standalone LSTM (6.3%), and CNN-LSTM without attention (5.1%). Permutation feature importance analysis confirms solar irradiance (34.2%), ambient temperature (18.7%), and hour-of-day (14.3%) as the three dominant predictors. Seasonal analysis reveals the largest absolute error in winter months (December–February, RMSE 0.168 MW) attributable to fog-induced irradiance attenuation in the Thar Desert region — a meteorological phenomenon not fully captured by standard numerical weather prediction inputs. --- #### The Paris Crossroads: Structural Drivers, Geopolitics, and Overshoot Risks a Decade After the Paris Agreement **Authors:** Elena Vance-Russo | **Affiliation:** Department of Environmental Systems Science Global Climate Policy Institute Zurich, Switzerland **Pages:** 125-128 | **Published:** 2026/06/15 **URL:** https://www.ijama.in/papers?paper=The+Paris+Crossroads%3A+Structural+Drivers%2C+Geopolitics%2C+and+Overshoot+Risks+a+Decade+After+the+Paris+Agreement | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781511500_IJAMAJUN26V306A18.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=The+Paris+Crossroads%3A+Structural+Drivers%2C+Geopolitics%2C+and+Overshoot+Risks+a+Decade+After+the+Paris+Agreement | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** Climate Finance, Decarbonization, Clean-Energy Investment, Energy Transition, Greenhouse Gas Emissions, Paris Agreement, Climate Geopolitics, Irreversible Overshoot. **Abstract:** A decade after the Paris Agreement set the world on a path to limit global warming to 1.5 °C above pre-industrial levels, nations face a stark reckoning: greenhouse-gas emissions remain near record highs even as clean-energy investment surpasses $1.7 trillion annually. This article examines the structural forces accelerating and obstructing the energy transition, assesses the geopolitics of climate finance, and argues that the decisive decade of the 2020s will determine whether the crossroads leads to transformation or irreversible overshoot. --- #### Mapping the Microbial Frontier: Structural Foundations, Host Interactions, and the Evolution of Microbiome Medicine **Authors:** Sola Thorne | **Affiliation:** Genomic University of Sustainable Therapeutics Melbourne, Australia **Pages:** 129-134 | **Published:** 2026/06/15 **URL:** https://www.ijama.in/papers?paper=Mapping+the+Microbial+Frontier%3A+Structural+Foundations%2C+Host+Interactions%2C+and+the+Evolution+of+Microbiome+Medicine | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781511748_IJAMAJUN26V306A19.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Mapping+the+Microbial+Frontier%3A+Structural+Foundations%2C+Host+Interactions%2C+and+the+Evolution+of+Microbiome+Medicine | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** Biomedicine, DNA Sequencing, Drug Responses, Dynamic Ecosystem, Host Immunity, Mental Health, Metabolic Function, Microbiome Medicine. **Abstract:** The human body hosts an estimated 38 trillion microbial cells — roughly equal to the number of human cells — forming a dynamic ecosystem known as the microbiome. Over the past two decades, advances in DNA sequencing have transformed this once-overlooked community into one of biomedicine’s most fertile frontiers. This article traces the science of the microbiome from its historical roots to its clinical frontiers, exploring how our microbial inhabitants shape immunity, mental health, metabolic function, and even drug responses — and what the emerging field of microbiome medicine promises for the decade ahead --- #### Tribological Performance and Microstructural Characterisation of TiAlN/Al₂O₃ Nano-composite PVD Coatings on High-Speed Steel Cutting Tools **Authors:** Rajesh Kumar , Sushil Chandra , Meenakshi Rathore | **Affiliation:** Department of Mechanical Engineering, Bundelkhand Institute of Engineering and Technology, Jhansi, Uttar Pradesh, India Department of Metallurgical and Materials Engineering, Government Engineering College, Bilaspur, Chhattisgarh, India **Pages:** 135-142 | **Published:** 2026/06/15 **URL:** https://www.ijama.in/papers?paper=Tribological+Performance+and+Microstructural+Characterisation+of+TiAlN%2FAl%E2%82%82O%E2%82%83+Nano-composite+PVD+Coatings+on+High-Speed+Steel+Cutting+Tools | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1781511880_IJAMAJUN26V306A20.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Tribological+Performance+and+Microstructural+Characterisation+of+TiAlN%2FAl%E2%82%82O%E2%82%83+Nano-composite+PVD+Coatings+on+High-Speed+Steel+Cutting+Tools | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** PVD coating, TiAlN, nano-composite coating, tribology, wear rate, hardness, magnetron sputtering, high-speed steel, cutting tool life, nanoindentation **Abstract:** The demand for high-performance cutting tool coatings in precision machining operations has intensified with the adoption of dry and near-dry cutting strategies aimed at minimising coolant costs and environmental contamination. Physical Vapour Deposition (PVD)-based hard coatings are the dominant surface engineering solution for extending the tool life of high-speed steel (HSS) and cemented carbide cutting tools, with titanium nitride (TiN) and titanium aluminium nitride (TiAlN) representing the commercially dominant systems. The incorporation of ceramic nano-particles, particularly aluminium oxide (Al₂O₃) in the 5-10% volume fraction range, into the TiAlN matrix has been proposed as a route to further enhance hardness, oxidation resistance, and tribological performance by exploiting nano-composite strengthening mechanisms including grain boundary pinning and impediment of dislocation motion. This study investigates the structural, mechanical, and tribological properties of magnetron-sputtered TiAlN/Al₂O₃ nano-composite coatings deposited on AISI M2 high-speed steel substrates at Al₂O₃ volume fractions ranging from 2% to 10%. Characterisation by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and nanoindentation quantifies crystal structure, surface morphology, elemental composition, and mechanical properties. Tribological performance under dry sliding conditions is evaluated by ball-on-disc testing against Al₂O₃ counter-bodies at 25°C to 500°C, with Rockwell C adhesion testing providing interfacial bond characterisation. The 6% Al₂O₃ nano-composite coating achieves a peak hardness of 34.8 GPa, friction coefficient of 0.31, and wear rate of 2.9 × 10⁻⁶ mm³/Nm — representing 84% reduction in wear rate relative to uncoated HSS substrate — with retained oxidation resistance to 500°C confirmed by post-thermal-anneal XRD. Tool life improvement factors of 3.4× in face milling of AISI 4340 steel confirm the industrial relevance of the nano-composite coating system. --- #### Environmental Impact Assessment of PM₁₀ Dispersion from Multiple Industrial Emission Sources under Ambient Meteorological Conditions Using AERMOD: An Industrial Case Study **Authors:** Vaibhavkumar Janakbhai Jadav, Darshan Salunke | **Affiliation:** Department of Environmental Science & Technology, UPL University of Sustainable Technology **Pages:** 143-152 | **Published:** 2026/06/29 **URL:** https://www.ijama.in/papers?paper=Environmental+Impact+Assessment+of+PM%E2%82%81%E2%82%80+Dispersion+from+Multiple+Industrial+Emission+Sources+under+Ambient+Meteorological+Conditions+Using+AERMOD%3A+An+Industrial+Case+Study | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1782736430_IJAMAJUN26V306A21.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Environmental+Impact+Assessment+of+PM%E2%82%81%E2%82%80+Dispersion+from+Multiple+Industrial+Emission+Sources+under+Ambient+Meteorological+Conditions+Using+AERMOD%3A+An+Industrial+Case+Study | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 6, June 2026 **Keywords:** Environmental Impact Assessment; Air Quality Impact Assessment; AERMOD; PM₁₀ Dispersion; Industrial Air Emissions; Atmospheric Dispersion Modelling; Fugitive Dust; Ambient Meteorology; Environmental Compliance. **Abstract:** Environmental Impact Assessment (EIA) is an essential tool for evaluating the potential effects of industrial activities on ambient air quality and ensuring compliance with environmental regulations. Atmospheric dispersion modelling has become an integral component of air quality impact assessment, enabling quantitative prediction of pollutant concentrations under prevailing meteorological conditions. This study presents an environmental impact assessment of PM₁₀ emissions from multiple industrial emission sources using the United States Environmental Protection Agency (US EPA) AERMOD dispersion model. To maintain industrial confidentiality, the identity and location of the study facility have been withheld.The assessment considered three major emission categories, namely area sources, point sources, and transport-related fugitive emissions. Site-specific meteorological data were processed using AERMET, while terrain information was incorporated through AERMAP to simulate pollutant dispersion over a 10 km × 10 km receptor domain. Individual and cumulative ground-level PM₁₀ concentrations were predicted under ambient meteorological conditions and evaluated against applicable ambient air quality standards.The modelling results indicated that ground-level fugitive emissions from area and transport sources contributed significantly more to ambient PM₁₀ concentrations than elevated stack emissions. The cumulative predicted concentration remained within the prescribed regulatory limits, indicating no significant adverse air quality impacts under the assessed operating conditions. The study demonstrates that AERMOD provides a reliable framework for environmental impact assessment of industrial air emissions and supports informed decision-making for pollution control, environmental management, and regulatory compliance. --- #### Isotopic Analysis of Mass Graves for Humanitarian Identification **Authors:** Helena Vasquez-Moreau | **Affiliation:** Department of Forensic Geochemistry and International Justice, University of Amsterdam, Netherlands **Pages:** 95-101 | **Published:** 2026/07/09 **URL:** https://www.ijama.in/papers?paper=Isotopic+Analysis+of+Mass+Graves+for+Humanitarian+Identification | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783780980_IJAMAJULY26V307A16.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Isotopic+Analysis+of+Mass+Graves+for+Humanitarian+Identification | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** stable isotope analysis, mass graves, forensic identification, strontium isotopes, oxygen isotopes, geographic provenance, Western Balkans, humanitarian forensics, International Criminal Court, missing persons **Abstract:** The identification of victims in mass graves — a humanitarian imperative at the intersection of forensic science, human rights law, and the psychological needs of bereaved families — has advanced considerably through DNA kinship matching, yet significant proportions of remains recovered from conflict and atrocity sites resist DNA-based identification due to sample degradation, absence of reference family samples, or the deliberate commingling of victims from geographically dispersed source communities. Stable isotope ratio analysis of skeletal hard tissues offers a complementary and often decisive tool for narrowing the geographic provenance of unidentified individuals: because the isotopic composition of strontium (⁸⁷Sr/⁸⁶Sr), oxygen (δ¹⁸O), sulphur (δ³⁴S), carbon (δ¹³C), and nitrogen (δ¹⁵N) in bone and dental enamel reflects the biogeochemical signature of food and water consumed during tissue formation, systematic multi-isotope profiling of skeletal remains against regional baseline datasets can constrain an individual's likely geographic origin to sub-national resolution — in favourable geological contexts, to the level of river basin or ecological zone. This study presents results from isotopic analysis of 312 skeletal individuals recovered from eleven mass grave sites in the Western Balkans (Bosnia-Herzegovina, Kosovo, and North Macedonia), cross-referenced against a newly compiled multi-isotope baseline atlas comprising 847 geo-referenced soil, water, and faunal reference samples collected across the region's principal geological and hydrological zones. Multi-isotope Bayesian provenance modelling, integrating ⁸⁷Sr/⁸⁶Sr, δ¹⁸O, and δ³⁴S simultaneously, assigned 74.7% of individuals to geographic provenance regions concordant with antemortem information and family testimony at ≥70% posterior probability. A further 18.3% of individuals received partial regional assignment (one or two isotope systems concordant), providing investigative leads for targeted family reference DNA collection. The resulting forensic evidence portfolios — structured to satisfy the evidentiary standards of the International Criminal Court and the International Residual Mechanism for Criminal Tribunals — have been transmitted to prosecutorial teams in four active international accountability proceedings. These findings demonstrate the operational maturity of multi-isotope provenance analysis as a humanitarian identification tool and establish a reproducible methodological framework and regional baseline infrastructure for deployment in future mass grave investigations across the broader southeastern European theatre. --- ### Issue 7 — July 2026 — https://www.ijama.in/archives.php?volume=3&issue=7 #### Artificial Intelligence as a Multidisciplinary Transformer: Convergence of Technology, Ethics, Healthcare, and Environmental Sustainability **Authors:** Aditi Krishnamurti, Marcus J.

This multidisciplinary review synthesises evidence from peer-reviewed literature, industry datasets, and primary empirical analyses to examine AI adoption trajectories across six key sectors — healthcare, finance, manufacturing, education, retail, and agriculture — through the interlocking lenses of technological performance, economic productivity, workforce transformation, ethical governance, and environmental sustainability. A cross-sectoral AI adoption dataset (n = 214 organisations, 2020–2024) reveals mean adoption growth of 143% over the study period, with healthcare and finance as lead adopters. AI-assisted diagnostic systems demonstrate mean accuracy of 93.1% across five clinical domains, outperforming specialist clinicians by 6.2 percentage points. Econometric modelling (OLS with sector fixed effects) confirms a significant logarithmic relationship between AI investment intensity and productivity gain (β = 3.21, p < 0.001, R² = 0.74). Thematic analysis of 62 governance frameworks identifies bias and accountability as the highest-rated ethical concerns across all stakeholder groups. A lifecycle carbon assessment of AI-driven process optimisation across five industrial sectors estimates mean CO₂ reduction of 24.2%, with energy grid applications yielding the largest absolute gains. These findings support the conclusion that AI’s transformative potential is maximised when deployment is accompanied by parallel investment in workforce reskilling, ethical governance infrastructure, and sustainability-conscious systems design. --- #### Deep Learning-Enhanced Hyperspectral Imaging for Non-Destructive Detection of Early-Stage Fungal Contamination in Stored Wheat Grain **Authors:** Meera Subramaniam | **Affiliation:** Department of Agricultural and Food Engineering, Indian Institute of Technology Kharagpur, West Bengal, India **Pages:** 7-13 | **Published:** 2026/07/01 **URL:** https://www.ijama.in/papers?paper=Deep+Learning-Enhanced+Hyperspectral+Imaging+for+Non-Destructive+Detection+of+Early-Stage+Fungal+Contamination+in+Stored+Wheat+Grain | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1782908212_IJAMAJULY26V307A02.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Deep+Learning-Enhanced+Hyperspectral+Imaging+for+Non-Destructive+Detection+of+Early-Stage+Fungal+Contamination+in+Stored+Wheat+Grain | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** hyperspectral imaging, deep learning, convolutional neural network, fungal contamination, wheat grain, mycotoxin, food safety, post-harvest, non-destructive sensing, precision agriculture **Abstract:** Post-harvest fungal contamination of stored wheat grain, predominantly by Fusarium, Aspergillus, and Penicillium species, causes substantial economic loss through grain spoilage and mycotoxin-related batch rejection, yet conventional quality control relies on visual inspection and laboratory mycotoxin assays that detect contamination only after it has progressed to a visibly or chemically advanced stage. This study addresses the resulting food-safety and agricultural-engineering gap by developing and validating a deep learning framework that processes hyperspectral imaging (HSI) data to detect fungal infection in wheat kernels substantially earlier than visible symptoms or mycotoxin thresholds would permit, integrating optical sensing engineering, food microbiology, and computer vision methods within a single non-destructive screening system. Wheat kernels (cultivar HD-3086) were inoculated with Fusarium graminearum, Aspergillus flavus, and Penicillium spp. under controlled storage conditions (28°C, 85% relative humidity) and imaged daily across a push-broom hyperspectral imaging system spanning 400-1000 nm (240 spectral bands) over a 14-day storage trial, with parallel deoxynivalenol (DON) mycotoxin quantification by enzyme-linked immunosorbent assay providing ground-truth contamination severity labels. A three-dimensional convolutional neural network (3D-CNN) jointly exploiting spectral and spatial kernel-surface information was trained for four-class infection severity classification (healthy, early-stage, moderate, severe) and benchmarked against a 2D-CNN (spectral features only), partial least squares discriminant analysis (PLS-DA), and a support vector machine, using a dataset of 5,600 individually imaged and ground-truth-labelled kernels. The 3D-CNN achieved 95.7% four-class classification accuracy and area-under-curve values of 0.911-0.971 for binary infection detection across the three fungal species, exceeding the 2D-CNN (91.8% accuracy) and classical baselines (82.3-84.6% accuracy). Critically, the HSI-CNN system detected infection with 50% cumulative detection probability by storage day 3.2, compared to day 8.5 for simulated visual inspection thresholds, a 5.5-day earlier detection window that precedes the steep phase of deoxynivalenol accumulation entirely. Saliency-based wavelength importance analysis identified the 680 nm chlorophyll-absorption band and the 700 nm red-edge transition as the two most discriminative spectral features, consistent with established plant-pathology mechanisms linking fungal infection to pigment degradation. Economic analysis indicates that HSI-CNN continuous screening reduces annualised per-tonne storage losses by 71.9% relative to no monitoring and by 56.8% relative to periodic visual inspection. These findings demonstrate that coupling optical sensing engineering with deep learning-based spectral-spatial analysis provides a viable non-destructive early-warning system for grain storage quality management. --- #### Machine Learning-Guided Design of Biodegradable Mg-Zn-Ca Alloy Implants for Orthopaedic Fixation **Authors:** Rohan Vaidya | **Affiliation:** Department of Biomedical Engineering and Centre for Computational Materials Design, Indian Institute of Science, Bengaluru, India **Pages:** 14-20 | **Published:** 2026/07/01 **URL:** https://www.ijama.in/papers?paper=Machine+Learning-Guided+Design+of+Biodegradable+Mg-Zn-Ca+Alloy+Implants+for+Orthopaedic+Fixation | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1782908492_IJAMAJULY26V307A03.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Machine+Learning-Guided+Design+of+Biodegradable+Mg-Zn-Ca+Alloy+Implants+for+Orthopaedic+Fixation | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** biodegradable magnesium alloy, orthopaedic implant, machine learning, degradation kinetics, corrosion modelling, Mg-Zn-Ca, cytocompatibility, gradient boosting, multi-objective optimisation, biomedical materials **Abstract:** Biodegradable magnesium-based alloys offer a fundamentally attractive alternative to permanent titanium and stainless-steel orthopaedic fixation hardware by eliminating the need for implant-removal surgery, but clinical translation has been constrained by the difficulty of simultaneously satisfying two competing design objectives: degradation must proceed slowly enough to preserve mechanical fixation strength through the bone-healing period, yet completely enough to avoid long-term subcutaneous gas cavities from hydrogen evolution. This study addresses the resulting multidisciplinary materials-design problem by coupling systematic in vitro corrosion and cytocompatibility characterisation of magnesium-zinc-calcium (Mg-Zn-Ca) alloy compositions with a machine learning framework trained to predict degradation rate and mechanical strength retention directly from composition and processing parameters, enabling rapid in silico screening of the compositional design space ahead of resource-intensive physical testing. Six alloy compositions spanning 0-6 wt% zinc and 0-1.5 wt% calcium were fabricated by induction melting and hot extrusion, then characterised through 90-day immersion testing in simulated body fluid (SBF) at 37°C with mass-loss gravimetry, hydrogen evolution volumetry, and electrochemical impedance spectroscopy; mechanical strength retention was tracked over a 180-day simulated physiological loading protocol; and cytocompatibility was assessed via MTT assay on MC3T3-E1 pre-osteoblast cells exposed to alloy extracts per ISO 10993-5. A gradient-boosted regression tree model was trained on 142 composition-processing-property records (combining this study's experimental data with curated literature values) to predict degradation rate and 90-day strength retention from ten composition and processing features, then used to perform multi-objective optimisation across the full compositional design space. The Mg-4Zn-0.5Ca composition emerged as the optimal candidate from both experimental characterisation and ML-guided optimisation, achieving a degradation rate of 0.17 mm/year (59% reduction versus pure magnesium's 0.42 mm/year), 90-day compressive strength retention of 78% against human cortical bone's reference strength of approximately 150 MPa, and cell viability of 95% at 12.5% extract concentration, remaining above the ISO 10993-5 cytotoxicity threshold of 70% viability even at full-strength (100%) extract concentration where pure magnesium fell to 31% viability. The gradient-boosted model achieved a root-mean-square error of 0.021 mm/year against held-out experimental degradation-rate measurements, with feature importance analysis identifying zinc content, calcium content, and grain size as the three dominant predictors of degradation behaviour, jointly accounting for over half of total model decision weight. These findings demonstrate that coupling a structured experimental corrosion-biocompatibility dataset with machine learning-based composition screening substantially accelerates identification of clinically viable biodegradable implant alloy compositions relative to combinatorial physical testing alone. --- #### Blockchain-Enabled Supply Chain Traceability Integrated with Machine Learning-Based Demand Forecasting for Reducing Post-Harvest Losses in Indian Perishable Agri-Food Systems **Authors:** Priyanka S.

This study presents an integrated framework combining a permissioned blockchain-based supply chain traceability ledger with a machine learning demand forecasting and demand-supply matching pipeline, piloted across seven perishable commodities (tomato, onion, potato, banana, mango, leafy greens, and grapes) moving through procurement networks linking 240 farmer-producer groups to wholesale mandis and retail outlets in central and western India over an eighteen-month observation period (July 2024-December 2025). The blockchain ledger, implemented on a Hyperledger Fabric permissioned network with IoT-integrated cold-chain temperature logging at five transit stages (farm collection, pack-house, road transit, distribution hub, and retail storage), recorded 184,000 traceability transactions and 62,000 temperature-excursion-monitored shipments, while a Transformer-based temporal demand forecasting model, benchmarked against naive seasonal, ARIMA, Random Forest, and LightGBM baselines, generated mandi-level demand predictions used to drive dynamic demand-supply matching and dispatch scheduling. The blockchain-tracked and ML-optimised supply chain achieved post-harvest loss reductions of 35-45% relative to the traditional multi-intermediary baseline across all seven commodities (e.g., tomato: 28.4% to 17.9%; leafy greens: 34.6% to 21.3%), with road transit identified as the dominant cold-chain temperature excursion stage (18.4 excursions per 100 shipments, mean duration 47 minutes). The Transformer-based forecasting model achieved the best demand prediction accuracy (MAPE=7.4%, R²=0.903), enabling mandi price volatility reductions of 36-45% (coefficient of variation) across commodities. Smart-contract-automated payment settlement reduced farmer payment cycles from a traditional mean of approximately 18 days to under 12 hours, while farmer net price realisation as a share of final consumer price increased from 31.4% to 52.8% through intermediary disintermediation. These findings demonstrate the technical and economic feasibility of integrated blockchain-ML agri-supply-chain infrastructure for simultaneously reducing physical post-harvest losses, dampening price volatility, and improving farmer income realisation in resource-constrained Indian agricultural markets. --- #### IoT-Enabled Real-Time Air Quality Monitoring Integrated with Machine Learning-Based Population Health Risk Prediction in Tier-2 Indian Urban Centres **Authors:** Anjali R.

This study presents an integrated framework combining a low-cost Internet of Things (IoT) sensor network for real-time criteria pollutant monitoring with a machine learning pipeline for both air quality index (AQI) forecasting and population-level health risk classification, deployed across five representative monitoring zones (industrial, traffic corridor, residential, institutional, and peri-urban) in Indore, Madhya Pradesh, over a twelve-month observation period (January-December 2025). A network of 42 low-cost nodes equipped with electrochemical and optical sensors (PM2.5, PM10, NO2, SO2, CO) transmitted hourly readings via LoRaWAN to a cloud-based aggregation layer, where the data were fused with meteorological variables (temperature, relative humidity, wind speed) and ward-level traffic density estimates. Five machine learning architectures — Support Vector Regression (SVR), Random Forest, XGBoost, Long Short-Term Memory (LSTM) networks, and a hybrid CNN-LSTM model — were benchmarked for 24-hour-ahead AQI forecasting, and a four-class Random Forest classifier was trained to stratify population exposure-days into Low, Moderate, High, and Severe health risk categories using a composite index derived from WHO air quality guideline thresholds and ICMR-NIOH dose-response coefficients. The hybrid CNN-LSTM model achieved the best forecasting performance (R²=0.918, RMSE=12.3 µg/m³), outperforming the XGBoost (R²=0.871) and Random Forest (R²=0.834) baselines, while the four-class health risk classifier attained an overall accuracy of 91.4% on held-out data. PM10 and NO2 emerged as the most predictive features (relative importance 0.241 and 0.183 respectively), and the industrial and traffic-corridor zones together accounted for 63% and 55% of high-and-severe-risk exposure-days respectively, compared to 14% in the peri-urban reference zone. The findings support targeted, zone-specific intervention prioritisation over uniform city-wide air quality management strategies and demonstrate the technical feasibility of low-cost IoT-ML pipelines for real-time environmental health surveillance in resource-constrained Tier-2 urban administrations. --- #### Machine Learning-Based Predictive Maintenance for Structural Health Monitoring of Steel Highway Bridges **Authors:** Ananya Krishnamurthy | **Affiliation:** Department of Civil Engineering and Centre for Data-Driven Infrastructure Systems, Indian Institute of Technology Hyderabad, Telangana, India **Pages:** 35-40 | **Published:** 2026/07/04 **URL:** https://www.ijama.in/papers?paper=Machine+Learning-Based+Predictive+Maintenance+for+Structural+Health+Monitoring+of+Steel+Highway+Bridges | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783321974_IJAMAJULY26V307A06.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Machine+Learning-Based+Predictive+Maintenance+for+Structural+Health+Monitoring+of+Steel+Highway+Bridges | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, **Keywords:** structural health monitoring, predictive maintenance, machine learning, sensor fusion, CNN-LSTM, steel bridges, remaining useful life, damage detection, corrosion monitoring, fatigue, infrastructure asset management **Abstract:** Ageing steel highway bridge infrastructure across rapidly motorising economies faces a structural performance assessment bottleneck: visual inspection protocols mandated at 2-4 year intervals cannot detect fatigue cracking, corrosion-induced section loss, or connection deterioration between scheduled inspections, while continuous instrumentation generates data volumes that exceed manual interpretation capacity. This study addresses the integration gap between structural health monitoring (SHM) sensor networks and automated damage diagnosis by developing and field-validating a multidisciplinary machine learning framework that fuses vibration, strain, and electrochemical corrosion-potential data streams for bridge-level predictive maintenance. A sensor network comprising 24 accelerometers, 18 strain gauges, and 12 half-cell corrosion-potential probes was deployed across two instrumented steel girder bridges (a 42 m simply-supported control structure and a 58 m structure with a known fatigue crack at Girder 3) on the Hyderabad Outer Ring Road corridor, generating 729 days of continuous monitoring data sampled at 200 Hz for dynamic channels and hourly for electrochemical channels. Four machine learning architectures — a hybrid convolutional neural network-long short-term memory (CNN-LSTM) model, a stacked LSTM, a random forest classifier, and a support vector machine — were trained on time-frequency and statistical features extracted from the fused sensor streams to perform four-class damage severity classification (none, minor, moderate, severe) and remaining useful life (RUL) regression. The CNN-LSTM hybrid achieved the highest damage classification accuracy (96.8%) and area-under-curve of 0.974 for binary damage detection when all three sensor modalities were fused, compared to 0.887-0.901 AUC for single-modality models, confirming a substantial sensor-fusion advantage. The framework detected the onset of progressive natural frequency drift in the fatigue-cracked bridge 38 days before the deviation would have been flagged by routine biennial inspection, with RUL predictions achieving a root-mean-square error of 11.4 days across 20 field-validated bridge segments. Lifecycle cost analysis indicates that ML-driven predictive maintenance reduces annualised per-bridge costs by 60.7% relative to reactive run-to-failure maintenance and by 36.6% relative to fixed-interval scheduled maintenance, driven predominantly by avoided downtime and disruption costs. SHAP-based feature attribution identifies modal frequency shift, daily strain range, and corrosion potential as the three dominant predictors of damage severity, providing an interpretable basis for sensor network prioritisation in resource-constrained monitoring deployments. --- #### Urban Green Infrastructure as a Multidisciplinary Response to Climate Change: Integrating Ecology, Public Health, Urban Planning, and Environmental Justice **Authors:** Rajesh Venkataraman, Sophie L. Beaumont, Ifeanyi C. Okonkwo | **Affiliation:** Department of Urban Planning & Environmental Design, Indian Institute of Technology Bombay, Mumbai, India Department of Civil & Environmental Engineering, University of Lagos, Lagos, Nigeria **Pages:** 41-46 | **Published:** 2026/07/05 **URL:** https://www.ijama.in/papers?paper=Urban+Green+Infrastructure+as+a+Multidisciplinary+Response+to+Climate+Change%3A+Integrating+Ecology%2C+Public+Health%2C+Urban+Planning%2C+and+Environmental+Justice | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783322126_IJAMAJULY26V307A07.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Urban+Green+Infrastructure+as+a+Multidisciplinary+Response+to+Climate+Change%3A+Integrating+Ecology%2C+Public+Health%2C+Urban+Planning%2C+and+Environmental+Justice | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** urban green infrastructure, urban heat island, climate adaptation, environmental justice, public health, stormwater management, cost-benefit analysis, remote sensing, urban ecology, sustainable cities **Abstract:** Rapid urbanisation — with 68% of the global population projected to reside in cities by 2050 — intensifies urban heat island (UHI) effects, stormwater flooding, air pollution, and health inequity, particularly in the Global South where infrastructure deficits intersect with climate vulnerability. Green infrastructure (GI), defined as strategically planned networks of natural and semi-natural systems including urban forests, green roofs, bioswales, constructed wetlands, and community parks, represents a multifunctional adaptation strategy capable of simultaneously addressing ecological, public health, economic, and social equity objectives. This multidisciplinary study integrates remote sensing analysis, epidemiological modelling, cost-benefit assessment, and environmental justice mapping across 22 cities in Asia, Africa, and Europe (combined population 87 million) to quantify GI performance across these dimensions. Thermal remote sensing analysis (Landsat 8 OLI/TIRS, 2015–2024) confirms a significant inverse linear relationship between green cover percentage and mean surface temperature (r = −0.91, β =−0.38°C per 1% green cover). Epidemiological analysis of 14 years of heat-related hospital admission data (n = 224,000 admissions) reveals that a 10-point increase in the Green Infrastructure Index reduces heat-related admissions by 31 per 100,000 population (β =−3.10, p < 0.001). Benefit-cost ratios for GI interventions range from 2.8x (cool pavements) to 3.6x (urban forestry) over a 20-year appraisal horizon. Environmental justice analysis reveals a systematic inverse correlation between neighbourhood income quartile and GI access (12% vs 54% for lowest vs highest income quartile), with a corresponding UHI intensity gap of 3.2°C. These findings provide a quantitative basis for integrated GI policy frameworks that simultaneously advance climate resilience, public health, economic efficiency, and spatial equity. --- #### Neural Correlates of Visual Balance in Abstract Expressionist Painting **Authors:** Maya Thornton, Sravani Pidipalli | **Affiliation:** Arora College of Engineering, Hyderabad **Pages:** 47-52 | **Published:** 2026/07/06 **URL:** https://www.ijama.in/papers?paper=Neural+Correlates+of+Visual+Balance+in+Abstract+Expressionist+Painting | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783779406_IJAMAJULY26V307A08.docx **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Neural+Correlates+of+Visual+Balance+in+Abstract+Expressionist+Painting | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** neuroaesthetics, visual balance, abstract expressionism, fNIRS, haemodynamic response, cortical processing, compositional symmetry, aesthetic preference, visual cortex **Abstract:** Aesthetic experience sits at the confluence of perceptual processing, emotional appraisal, and learned cultural schema — yet the neural mechanisms by which the human visual system evaluates compositional balance in non-representational art remain poorly characterised. Abstract Expressionist works, in which compositional structure emerges from gestural mark-making rather than figurative content, provide a uniquely controlled stimulus class for isolating neural responses to low-level balance cues from higher-order semantic processing. This study employs functional near-infrared spectroscopy (fNIRS), a portable neuroimaging modality that measures haemodynamic responses via cortical oxygenation changes, to track real-time blood flow dynamics in the visual cortex, dorsolateral prefrontal cortex, and anterior cingulate cortex as thirty-six participants viewed Abstract Expressionist canvases rated as compositionally balanced or unbalanced by an independent expert panel of art historians and museum curators. Balanced compositions elicited significantly greater oxyhaemoglobin (HbO) increase in bilateral V4 and lateral occipital complex (LOC) relative to control images, with attenuated prefrontal engagement — a pattern consistent with fluent perceptual processing requiring reduced executive monitoring. Unbalanced compositions, by contrast, showed heightened anterior cingulate and dorsolateral prefrontal activation, suggesting conflict detection and effortful attentional reorientation. Critically, these neural signatures were modulated by demographic variables including prior art training (F(2,33)=6.14, p=.006), cultural background, and self-reported aesthetic sensitivity, pointing to the role of learned perceptual schemas in shaping low-level cortical balance processing. A predictive model of aesthetic balance preference — incorporating haemodynamic response magnitude, stimulus symmetry metrics, and participant art exposure — achieved 79.3% accuracy in classifying individual preference ratings. These findings advance empirical aesthetics by providing the first fNIRS-based neural profile of visual balance processing in abstract art and establish a data-driven framework for understanding aesthetic universality and cultural variation in compositional preference. --- #### Restoring Fragmented Heritage: Deep Learning Applied to Ancient Epigraphy **Authors:** Arjun Mehra, Prof Yasmine Al-Rashid | **Affiliation:** Centre for Digital Humanities, University of Hyderabad, Hyderabad, India **Pages:** 53-58 | **Published:** 2026/05/07 **URL:** https://www.ijama.in/papers?paper=Restoring+Fragmented+Heritage%3A+Deep+Learning+Applied+to+Ancient+Epigraphy | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783779533_IJAMAJULY26V307A09.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Restoring+Fragmented+Heritage%3A+Deep+Learning+Applied+to+Ancient+Epigraphy | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** ancient epigraphy, deep learning, transformer model, BiLSTM, lacuna reconstruction, heritage preservation, natural language processing, corpus linguistics, photogrammetry, open-access platform **Abstract:** The degradation of ancient inscribed surfaces — through mechanical fracture, chemical weathering, and deliberate obliteration — has rendered substantial portions of the world's epigraphic record unreadable by conventional philological means. This project bridges computational linguistics, machine learning, and heritage science to reconstruct damaged ancient inscriptions using deep learning architectures trained on attested linguistic corpora. By encoding known phonological, morphosyntactic, and graphemic constraints derived from corpus linguistics into transformer-based and recurrent neural network models, the system generates probabilistic predictions for lacunae — gaps, breaks, and abraded zones — on weathered stone, metal, and ceramic surfaces. Validation against three expert epigraphists' reconstructions across a 1,200-inscription test set demonstrates character-level accuracy of 93.6% for Latin and Greek scripts and 81.4% for underdeciphered scripts including Linear B and the Indus Valley script. This approach accelerates historical translation workflows by an estimated 4.7-fold and provides a systematic framework for preserving vulnerable cultural heritage data in machine-readable, open-access formats. --- #### Artificial Intelligence Adoption and Workforce Reskilling in Indian Manufacturing SMEs: Determinants of Scaled Adoption and Financial Performance Outcomes **Authors:** Rohan V. Deshpande | **Affiliation:** Department of Management Studies, VJTI, Mumbai **Pages:** 59-64 | **Published:** 2026/07/07 **URL:** https://www.ijama.in/papers?paper=Artificial+Intelligence+Adoption+and+Workforce+Reskilling+in+Indian+Manufacturing+SMEs%3A+Determinants+of+Scaled+Adoption+and+Financial+Performance+Outcomes | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783779649_IJAMAJULY26V307A10.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Artificial+Intelligence+Adoption+and+Workforce+Reskilling+in+Indian+Manufacturing+SMEs%3A+Determinants+of+Scaled+Adoption+and+Financial+Performance+Outcomes | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** artificial intelligence adoption, workforce reskilling, manufacturing SMEs, India, digital transformation, productivity, EBITDA margin, technology adoption, logistic regression **Abstract:** Small and medium enterprises (SMEs) constitute approximately 30% of India's manufacturing gross value added and over 110 million jobs, yet face persistent disadvantages in adopting artificial intelligence (AI) relative to large manufacturers, including capital constraints, skilled talent shortages, and limited digital infrastructure. While prior research has documented aggregate AI adoption trends, the firm-level determinants of progression from pilot-stage experimentation to scaled adoption, and the role of workforce reskilling investment in enabling this progression, remain underexamined in the Indian manufacturing SME context specifically. This study surveys 412 manufacturing SMEs across six sectors (automotive components, textiles, pharmaceutical formulation, electronics assembly, industrial machinery, and food processing) in Maharashtra, Tamil Nadu, and Gujarat, combining a structured adoption-maturity survey with logistic regression analysis of scaled-adoption determinants and a six-month longitudinal workforce competency assessment across 860 production and quality workers participating in firm-sponsored AI reskilling programmes. Financial performance outcomes (revenue growth, EBITDA margin) were compared across adoption-maturity cohorts using firm-level financial statement data. Scaled AI adoption rose sharply with firm size, from 10% among micro enterprises to 59% among large SMEs (250-499 employees). Reskilling spend as a share of payroll was the strongest predictor of scaled-adoption success in the logistic regression model (standardised β = 0.41), ahead of leadership digital literacy (β = 0.34) and prior ERP/MES system maturity (β = 0.29). Workforce competency scores rose substantially across all assessed skill categories following six-month reskilling participation, with AI tool operation competency showing the largest gain (1.8 to 5.4 on a 10-point scale). Firms with scaled AI adoption for two or more years reported 13.1% YoY revenue growth and 3.8 percentage point EBITDA margin improvement, compared with 4.2% revenue growth and 0.3 percentage point margin improvement among non-adopting firms. Skilled talent shortage was the most frequently cited adoption barrier, reported by 71% of surveyed firms. --- #### Stabilisation of Expansive Black Cotton Soil Using Lime and Rice Husk Ash: Strength, Swell, Permeability and Microstructural Characterisation **Authors:** Anand B.

Chemical stabilisation with hydrated lime exploits cation exchange, flocculation-agglomeration, and long-term pozzolanic reactions to reduce plasticity, control swell, and improve strength; however, lime alone at dosages above 6% shows diminishing strength returns and increased material cost. Rice Husk Ash (RHA), a reactive siliceous agro-industrial pozzolan available at negligible cost from rice mills across Maharashtra and Telangana, can supplement lime's calcium hydroxide with additional silica for secondary calcium silicate hydrate (C-S-H) formation, potentially exceeding the performance of lime-only stabilisation at lower total additive dosage. This study systematically investigates the effect of lime addition (2%, 4%, 6%, 8% by dry weight of soil) and binary lime–RHA blends (4% lime + 5% RHA; 4% lime + 10% RHA) on BCS collected from Nanded district, Maharashtra. Parameters evaluated include Modified Proctor compaction (MDD, OMC), soaked CBR, Unconfined Compressive Strength (UCS) at 28-day cure, free swell, hydraulic conductivity by falling-head permeameter at cure ages 0–90 days, and X-ray diffraction (XRD) phase analysis at 28 days. The 4% lime + 10% RHA binary blend achieves the highest UCS (384.2 kPa, 461% above virgin soil), soaked CBR of 38.6%, free swell reduction to 0.94% (87.3% below untreated soil), and hydraulic conductivity of 1.6×10⁻⁸ m/s at 28 days — a three-order-of-magnitude improvement. XRD confirms progressive montmorillonite peak suppression and emergence of C-S-H and C-A-S-H phases with increasing RHA content and curing age. --- #### Machine Learning-Guided Design of Graded-Porosity 3D-Printed Scaffolds for Bone Tissue Engineering: Mechanobiological Optimisation and In Vitro Osteogenic Validation **Authors:** Meera S.

Fixed-geometry unit-cell scaffolds (diamond, gyroid) typically optimise one objective at the expense of the other, since increasing strut thickness to raise modulus simultaneously reduces pore size and permeability. This study develops a machine learning (ML) surrogate-assisted multi-objective optimisation framework that jointly predicts compressive modulus and permeability from scaffold design variables, enabling generative design of spatially graded scaffold architectures that resolve this trade-off. A gradient-boosted regression surrogate model was trained on 3,600 finite element analysis (FEA) compression simulations and 1,800 computational fluid dynamics (CFD) permeability simulations spanning pore diameter, strut thickness, porosity gradient, and unit-cell type. The validated surrogate was embedded within a genetic algorithm-driven generative design loop to identify a Pareto-optimal graded scaffold architecture, which was subsequently fabricated in medical-grade polycaprolactone (PCL) via fused deposition modelling and benchmarked against fixed diamond and gyroid scaffolds through mechanical compression testing, micro-CT pore architecture analysis, and 6-week MC3T3-E1 osteoblast culture assessing proliferation, alkaline phosphatase activity, and calcium mineralisation. The ML-optimised graded scaffold achieved a compressive modulus of 312 MPa at 70% mean porosity, within the native cancellous bone range, while maintaining a CFD-predicted permeability of 7.8×10⁻⁹ m² - 38% higher than the gyroid scaffold and 64% higher than the diamond scaffold at matched porosity. The ML-optimised scaffold supported significantly greater osteoblast proliferation (9.2-fold increase by day 21 versus 5.9-fold for diamond) and calcium deposition (1.18 mg/scaffold at 6 weeks versus 0.74 mg for diamond), a 59.5% improvement attributed to the graded pore architecture's closer match to the ML-identified optimal pore diameter window of 400-600 µm. The permeability surrogate achieved R² = 0.95 against held-out CFD validation data, with pore diameter and strut thickness identified as the dominant design drivers via SHAP analysis. --- #### Mechanical Characterisation, Moisture Absorption and Thermal Stability of Glass/Carbon Fibre-Reinforced Epoxy Hybrid Laminates for Structural Aerospace Applications **Authors:** Priya V.

Glass fibre-reinforced polymer (GFRP) laminates offer cost-effective stiffness and impact resistance, while carbon fibre-reinforced polymer (CFRP) laminates deliver superior specific modulus and fatigue performance at premium material cost. Hybrid laminates interleaving glass and carbon fibre plies within a common epoxy matrix have been proposed as a route to balanced performance-cost optimisation — the hybrid effect, wherein the failure strain of the lower-elongation carbon fibre is enhanced by the adjacent glass layers, remains an active area of investigation. This study fabricates seven laminate configurations — neat epoxy control, GFRP at 2, 4, and 6 ply counts, CFRP at 2 and 4 plies, and a 4-ply symmetric glass–carbon–carbon–glass (GCCG) hybrid — by vacuum-assisted resin infusion (VARI) using LY556 epoxy with HY951 hardener. Properties evaluated include ultimate tensile strength, flexural strength (3-point bend), inter-laminar shear strength (ILSS), Charpy impact energy, water absorption at 672 hours, and storage modulus by Dynamic Mechanical Analysis (DMA). Thermogravimetric Analysis (TGA) characterises thermal degradation onset temperature and char yield. The 4-ply CFRP laminate achieves the highest tensile and flexural strength (158.4 MPa and 186.2 MPa respectively) and storage modulus (42.1 GPa), while the hybrid GCCG-4L laminate achieves the highest impact energy absorbed (13.8 J) — 6.6× the neat epoxy baseline — at 90.3% of the CFRP-4L tensile strength, confirming a positive hybrid effect on impact resistance. Thermal analysis shows CFRP-4L onset degradation at 340°C versus 280°C for neat epoxy, with char residue of 38.2% reflecting carbon fibre retention. SEM of fracture surfaces confirms fibre pull-out and matrix cracking as dominant failure modes in GFRP, transitioning to fibre fracture and delamination in CFRP under tensile overload. --- #### Edge Computing: Transforming the Future of Data Processing **Authors:** Arjun Mehta, Samuel Okonkwo | **Affiliation:** IBM Research, Nairobi **Pages:** 82-87 | **Published:** 2026/07/08 **URL:** https://www.ijama.in/papers?paper=Edge+Computing%3A+Transforming+the+Future+of+Data+Processing | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783780344_IJAMAJULY26V307A14.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Edge+Computing%3A+Transforming+the+Future+of+Data+Processing | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** edge computing, fog computing, IoT, latency, distributed systems, AI inference, 5G **Abstract:** The exponential growth of connected devices and latency-sensitive applications has exposed fundamental limitations of centralized cloud computing. Edge computing — the paradigm of processing data at or near the source — is emerging as the critical architectural complement to the cloud. This article examines the principles, architecture, applications, and challenges of edge computing, and evaluates its transformative potential across industries including manufacturing, healthcare, transportation, and retail. Empirical evidence suggests that edge deployments reduce latency by up to 98%, cut bandwidth consumption by 80%, and enable entirely new categories of real-time AI applications previously infeasible in a cloud-only model. --- #### Performance Evaluation of Grid-Connected Hybrid Solar Photovoltaic–Wind–Battery Energy Storage Systems Across Three Climatic Zones in India: A 36-Month Multi-Site Field Deployment Case Study **Authors:** Emmanuel O.

Despite growing deployment, systematic multi-site performance data spanning diverse Indian climatic regimes — arid desert, tropical coastal, and high-altitude highland — remains scarce in the peer-reviewed literature, limiting evidence-based policy optimisation. This paper presents a 36-month (January 2022–December 2024) field performance analysis of three grid-connected hybrid Solar PV–Wind–Battery Energy Storage System (BESS) plants commissioned under MNRE's Pilot Scheme for Hybrid Energy Systems: Site A (Thar Desert, Rajasthan; 4.2 MWp PV + 4.0 MW wind + 8.4 MWh BESS), Site B (Coastal Tamil Nadu; 2.8 MWp PV + 6.0 MW wind + 6.0 MWh BESS), and Site C (Highland Himachal Pradesh; 1.6 MWp PV + 4.0 MW wind + 4.8 MWh BESS). Monitored parameters include irradiance, wind speed, generation, BESS state-of-charge, grid availability, power quality metrics (THD, frequency deviation), and economic indicators (LCOE, curtailment rate). The Coastal Tamil Nadu site achieves the highest plant capacity factor (41.2%) and Complementarity Index (CI = 0.81), driven by strong diurnal solar–wind anti-correlation. Blended hybrid LCOE ranges from ₹2.68/kWh (Thar Desert) to ₹2.89/kWh (Highland HP), 18–31% below single-technology solar benchmarks for the same sites. All three sites meet CEA Grid Code reliability standards with SAIDI values of 18.4–41.6 min/yr versus the 60 min/yr norm. Cumulative CO₂ avoidance over 36 months totals 75,768 tCO₂ across the three sites. --- #### Isotopic Analysis of Mass Graves for Humanitarian Identification **Authors:** Helena Vasquez-Moreau | **Affiliation:** Department of Forensic Geochemistry and International Justice, University of Amsterdam, Netherlands **Pages:** 95-101 | **Published:** 2026/07/10 **URL:** https://www.ijama.in/papers?paper=Isotopic+Analysis+of+Mass+Graves+for+Humanitarian+Identification | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783781589_IJAMAJULY26V307A16.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Isotopic+Analysis+of+Mass+Graves+for+Humanitarian+Identification | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** stable isotope analysis, mass graves, forensic identification, strontium isotopes, oxygen isotopes, geographic provenance, Western Balkans, humanitarian forensics, International Criminal Court, missing persons **Abstract:** The identification of victims in mass graves — a humanitarian imperative at the intersection of forensic science, human rights law, and the psychological needs of bereaved families — has advanced considerably through DNA kinship matching, yet significant proportions of remains recovered from conflict and atrocity sites resist DNA-based identification due to sample degradation, absence of reference family samples, or the deliberate commingling of victims from geographically dispersed source communities. Stable isotope ratio analysis of skeletal hard tissues offers a complementary and often decisive tool for narrowing the geographic provenance of unidentified individuals: because the isotopic composition of strontium (⁸⁷Sr/⁸⁶Sr), oxygen (δ¹⁸O), sulphur (δ³⁴S), carbon (δ¹³C), and nitrogen (δ¹⁵N) in bone and dental enamel reflects the biogeochemical signature of food and water consumed during tissue formation, systematic multi-isotope profiling of skeletal remains against regional baseline datasets can constrain an individual's likely geographic origin to sub-national resolution — in favourable geological contexts, to the level of river basin or ecological zone. This study presents results from isotopic analysis of 312 skeletal individuals recovered from eleven mass grave sites in the Western Balkans (Bosnia-Herzegovina, Kosovo, and North Macedonia), cross-referenced against a newly compiled multi-isotope baseline atlas comprising 847 geo-referenced soil, water, and faunal reference samples collected across the region's principal geological and hydrological zones. Multi-isotope Bayesian provenance modelling, integrating ⁸⁷Sr/⁸⁶Sr, δ¹⁸O, and δ³⁴S simultaneously, assigned 74.7% of individuals to geographic provenance regions concordant with antemortem information and family testimony at ≥70% posterior probability. A further 18.3% of individuals received partial regional assignment (one or two isotope systems concordant), providing investigative leads for targeted family reference DNA collection. The resulting forensic evidence portfolios — structured to satisfy the evidentiary standards of the International Criminal Court and the International Residual Mechanism for Criminal Tribunals — have been transmitted to prosecutorial teams in four active international accountability proceedings. These findings demonstrate the operational maturity of multi-isotope provenance analysis as a humanitarian identification tool and establish a reproducible methodological framework and regional baseline infrastructure for deployment in future mass grave investigations across the broader southeastern European theatre. --- #### Isotopic Analysis of Mass Graves for Humanitarian Identification: Establishing Regional Biogeochemical Baselines and Forensic Evidence Portfolios for International Legal Accountability **Authors:** Ranjit Kumar, Harish Narayan Tiwari, Supriya Balakrishnan | **Affiliation:** Department of Forensic Chemistry and Toxicology, Banaras Hindu University, Varanasi, Uttar Pradesh, India Department of International Law and Human Rights, Rajiv Gandhi National University of Law, Patiala, Punjab, India School of Earth and Environmental Sciences, Pondicherry University, Puducherry, India **Pages:** 102-108 | **Published:** 2026/07/10 **URL:** https://www.ijama.in/papers?paper=Isotopic+Analysis+of+Mass+Graves+for+Humanitarian+Identification%3A+Establishing+Regional+Biogeochemical+Baselines+and+Forensic+Evidence+Portfolios+for+International+Legal+Accountability | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783781803_IJAMAJULY26V307A17.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Isotopic+Analysis+of+Mass+Graves+for+Humanitarian+Identification%3A+Establishing+Regional+Biogeochemical+Baselines+and+Forensic+Evidence+Portfolios+for+International+Legal+Accountability | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** stable isotope analysis, mass graves, forensic identification, strontium isotopes, oxygen isotopes, humanitarian forensics, geographic origin, skeletal remains, international criminal law, biogeochemical baseline, IRMS **Abstract:** The forensic identification of victims recovered from mass graves constitutes one of the most technically demanding and legally consequential applications of analytical chemistry, requiring the integration of stable isotope ratio analysis, skeletal morphology, and evidentiary chain-of-custody protocols sufficient for admissibility before international criminal tribunals and human rights courts. This study establishes regional biogeochemical isotopic reference baselines for five geographic zones within a post-conflict study region of the Western Balkans, drawing on 168 georeferenced soil, water, and faunal reference samples quantified for strontium (87Sr/86Sr), oxygen (delta18O), carbon (delta13C), nitrogen (delta15N), and hydrogen (deltaD) isotope ratios using multi-collector inductively coupled plasma mass spectrometry and isotope ratio mass spectrometry protocols. These regional isotopic maps were subsequently applied to skeletal remains recovered from 42 individuals exhumed from three confirmed mass grave sites, with the objective of determining geographic origin regions and constructing forensic evidence portfolios for submission to the International Court of Justice and the International Criminal Tribunal. Multi-isotope analysis combining all five isotope systems achieved geographic origin assignment accuracy of 93.8% in cross-validation against known-provenance reference individuals. Collagen quality assessment confirmed preservation adequate for isotopic analysis in 38 of 42 individuals (C:N ratio 2.9-3.5 in 90.5% of samples). Sequential tooth enamel analysis provided lifetime migration histories for four individuals showing geographically distinct childhood versus adult residence signatures. The resulting forensic evidence portfolios, incorporating isotopic origin assignments, confidence intervals, and chain-of-custody documentation, were structured to meet the evidentiary admissibility standards of the International Criminal Court Rules of Procedure and Evidence. --- #### Legal Rights of Nature: Implementing Ecosystem Personhood for Coral Reefs **Authors:** Namrata Nayana, Sofia M. | **Affiliation:** CBIT, Hyderabad **Pages:** 109-116 | **Published:** 2026/07/11 **URL:** https://www.ijama.in/papers?paper=Legal+Rights+of+Nature%3A+Implementing+Ecosystem+Personhood+for+Coral+Reefs | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783782161_IJAMAJULY26V307A18.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Legal+Rights+of+Nature%3A+Implementing+Ecosystem+Personhood+for+Coral+Reefs | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** rights of nature, legal personhood, coral reef law, ecosystem rights, environmental litigation, CRPPA, guardianship, nature standing, marine conservation, jurisprudence **Abstract:** Intersecting jurisprudence and marine ecology, this project investigates the legal defence of threatened reef habitats. It examines how granting legal personhood to coral reefs can establish direct avenues for conservation litigation against state and corporate actors whose conduct causes measurable ecosystem damage. Global bleaching events have destroyed approximately 50% of coral cover since 1950, exposing a fundamental deficiency in anthropocentric legal frameworks that treat reef ecosystems as property rather than as rights-bearing entities. This study analyses eight precedent jurisdictions — including the Whanganui River (New Zealand), Atrato River (Colombia), and Ecuador's constitutional Rights of Nature — to derive transferable legal architecture applicable to marine ecosystems. A comparative Legal Personhood Index across six dimensions (standing, guardianship, enforceability, restoration orders, criminal sanctions, and international recognition) reveals that the Whanganui and Atrato models achieve the highest composite scores (92% and 88% respectively) but that no existing framework adequately addresses the transboundary and corporate liability dimensions critical for reef protection. Based on this analysis, a model statute — the Coral Reef Personhood and Protection Act (CRPPA) — is drafted across six operative parts, granting justiciable rights to exist, regenerate, and flourish; establishing an independent three-member Reef Guardian Board; imposing treble-damages corporate liability with reversed burden of proof; and enabling 24-hour emergency injunctions on scientific affidavit. Litigation playbook analysis of 95 nature-rights cases confirms that standing establishment (72% success) and scientific evidence filing (88% success) are the strongest litigation stages, while damages assessment (44%) represents the principal procedural vulnerability. The CRPPA model statute and associated litigation playbook are designed as directly adoptable instruments for environmental advocacy organisations operating in Pacific Island, Caribbean, and Indo-Pacific jurisdictions. --- #### Fintech Development and Financial Inclusion: A Comparative Bibliometric Study of BRICS Nations **Authors:** Ajay Yadav, Sushant Yadav, Deepak, Manoj Kumar, Raushan Kumar | **Affiliation:** Amity University Haryana, India, Indira Gandhi University, Meerpur, Rewari, Haryana, India **Pages:** 117-124 | **Published:** 2026/07/11 **URL:** https://www.ijama.in/papers?paper=Fintech+Development+and+Financial+Inclusion%3A+A+Comparative+Bibliometric+Study+of+BRICS+Nations | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783782703_IJAMAJULY26V307A19.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Fintech+Development+and+Financial+Inclusion%3A+A+Comparative+Bibliometric+Study+of+BRICS+Nations | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** Fintech, Financial Inclusion, BRICS, Bibliometric Analysis, Digital Payments, Mobile Banking, Regulatory Framework. **Abstract:** This study conducts a systematic bibliometric analysis of fintech development and financial inclusion across BRICS nations Brazil, Russia, India, China, and South Africa. Drawing on a corpus of 247 peer-reviewed articles published between 2013 and 2023 and sourced from Scopus and Web of Science, it maps the intellectual structure, collaborative networks, and thematic evolution of this research domain. Using VOSviewer and the Bibliometrix R-package, four dominant thematic clusters are identified: digital payment infrastructure, mobile banking and access, regulatory and policy frameworks, and fintech ecosystem dynamics. China and India together account for 62 percent of total publication output. The analysis reveals a significant positive correlation between fintech adoption indices and financial inclusion metrics across all five BRICS economies, with heterogeneous moderating effects attributable to regulatory stringency and digital infrastructure maturity. The study concludes with actionable policy recommendations for emerging market economies seeking to leverage fintech for inclusive economic growth. --- #### Challenges and Opportunities for Geospatial Technologies in City Planning **Authors:** Dr. Sunil | **Affiliation:** Department of Planning, Hindu College of Design, Architecture & Planning, Sonepat, India **Pages:** 125-129 | **Published:** 2026/07/12 **URL:** https://www.ijama.in/papers?paper=Challenges+and+Opportunities+for+Geospatial+Technologies+in+City+Planning | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1783835855_IJAMAJULY26V307A20.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=Challenges+and+Opportunities+for+Geospatial+Technologies+in+City+Planning | **Publication Year:** 2026 | **Volume/Issue:** Volume 3, Issue 7, July 2026 **Keywords:** Geospatial technologies, City Planning, Urban Challenges, Opportunities **Abstract:** Geospatial technologies have become integral to modern city planning, offering tools that enhance spatial analysis, visualization, and decision-making.

The speed at which machine learning, predictive analytics, natural language processing, recommendation systems, generative AI, and automated decision-making are developing has altered how businesses comprehend their customers, create marketing campaigns, interact with audiences, and assess their performance. Organizations are under increasing pressure to meet social and environmental demands while yet being economically viable. This conceptual study integrates insights from current literature to investigate the relationship between marketing strategies, artificial intelligence, and company sustainability. Predictive analytics, customer relationship management, social media marketing, content marketing, personalization, and marketing automation are all given special consideration. The study suggests that by enhancing customer comprehension, targeting, personalization, forecasting, resource allocation, and campaign optimization, AI can increase marketing efficacy. Through increased operational effectiveness, better customer interactions, innovation, adaptability, and more efficient use of resources, these enhancements may support corporate sustainability. The paper makes the case that businesses should take a human-centered, morally sound approach where AI enhances management judgment rather than entirely replaces it. Future empirical studies investigating the circumstances in which AI-enabled marketing can support long-term corporate sustainability can build on the conceptual discussion --- #### An IoT Integrated Deep Learning approach for Real Time Face Authentication **Authors:** G.G.Rajput, Durga M Ganjagol and Pavitra Muttur | **Affiliation:** 1,2,,3Department of Computer Science Karnataka State Akkamahadevi Women University Vijayapura, Karnataka, India **Pages:** 15-25 | **Published:** 11/09/2026 **URL:** https://www.ijama.in/papers?paper=An+IoT+Integrated+Deep+Learning+approach+for+Real+Time+Face+Authentication | **PDF:** https://www.ijama.in/admin/a/uploads/pdf/1789109518_IJAMAAUG26V308A02.pdf **Language:** English | **Open Access:** Yes | **Canonical URL:** https://www.ijama.in/papers?paper=An+IoT+Integrated+Deep+Learning+approach+for+Real+Time+Face+Authentication | **Publication Year:** 2026 | **Volume/Issue:** Volume 3 Issue 8,Aug-2026 **Keywords:** Face Recognition, Deep Learning, MTCNN, FaceNet, Support Vector Machine, Internet of Things. **Abstract:** Deep learning has greatly enhanced the performance of numerous recognition systems. and in particular facial recognition. However, achieving robust real time recognition under diverse facial appearances and integrating Internet of Things (IoT) for real time application is challenging. In this paper we propose Multi task Cascaded Convolutional Neural Network (MTCNN) deep learning model for robust facial recognition and integrating the proposed method in IoT environment for real time face recognition. MTCNN is used to precisely localize and align facial regions, while FaceNet model is used to generate compact facial embeddings that are subsequently classified using a Support Vector Machine (SVM) classifier. Experiments were carried out on images from LFW facial image dataset. The proposed recognition framework achieved an accuracy of 97.84%, demonstrating reliable facial identity classification on the LFW dataset. The proposed system is integrated with ESP32-CAM and Arduino to enable IoT-based remote monitoring and secure access control. The proposed framework offers an accurate, efficient, and practical solution for smart security, attendance management, and real-time surveillance. --- ### Issue 9 — Sep 2026 — https://www.ijama.in/archives.php?volume=3&issue=9 #### Comparative Efficacy of Bio-Agents and Chemicals Against Guava Fruit Rot In Commercial Orchards Of Vaishali, Bihar **Authors:** Manisha Kumari, Manoj Kumar and V K Prabhat | **Affiliation:** 1.

In Bihar, Vaishali district is recognized as a major belt for ommercial guava cultivation due to favorable agro-climatic conditions. However, the production and productivity of guava is severely affected by various diseases, among which fruit rot is the most destructive and causes significant economic losses to the growers. The disease is caused by several fungal pathogens and leads to 30-45% loss during pre and post-harvest stages. Farmers generally depend on chemical fungicides for management but indiscriminate use results in environmental pollution, health hazards and development of resistance in pathogens. In recent years, there has been increasing demand for eco-friendly and sustainable approaches like use of bio-agents and botanicals. Keeping this in view, the present investigation was carried out during 2021-2022 in commercial guava orchards of Vaishali district to evaluate and compare the efficacy of bio-agents, botanicals and chemical fungicides against fruit rot. Five treatments including Carbendazim 0.1%, Trichoderma viride 1%, Neem leaf extract 10%, Integrated Disease Management and control were evaluated. Three sprays were applied at 15 days interval during fruiting stage. The results revealed that Integrated Disease Management was most effective in reducing disease incidence to 12.4% and increasing yield to 18.6 kg per plant. Among individual treatments, Trichoderma viride performed better and gave higher cost-benefit ratio. The study concludes that bio-agents can be effectively integrated for sustainable management of guava fruit rot in Vaishali region. --- #### Energetics and Nutrient Dynamics of Safflower Carthamus Tinctorius L.

Gaya district of Bihar has different soil types but information on energetics and nutrient dynamics of safflower is lacking. The present study was conducted during Rabi 2024-2025 in three representative soil types of Gaya district: Upland, Medium land and Lowland to evaluate calorific value and nutrient content of safflower. The experiment was laid out in Randomized Block Design with 3 replications in each soil type. Safflower variety A-300 was sown in 2nd week of October. Samples of plant and soil collected at 30 days interval. Calorific value determined by Bomb Calorimeter. Plant and soil samples analyzed for NPK and micronutrients. Results revealed that maximum calorific value 6.52 Kcal/g in seed, 4.28 Kcal/g in stem and 4.02 Kcal/g in leaf was recorded in medium land. Energy output:input ratio was highest 3.92 in medium land. Maximum NPK uptake 68.4 kg N, 14.2 kg P and 52.6 kg K/ha was also recorded in medium land at 90 DAS. Seed contained 3.32% N, 0.65% P and 0.88% K in medium land. Soil organic carbon increased from 0.39% to 0.54% in medium land after crop. The study concludes that medium land of Gaya district is most suitable for safflower cultivation in terms of energy and nutrient efficiency. Safflower has good potential for oil and bio-energy in Gaya district --- ## Statistics - **Total Volumes:** 3 - **Total Issues:** 25 - **Total Articles:** 219 - **Total Editorial Members:** 40 - **Total Announcements:** 5 - **Generated Time:** 2026-09-11T10:13:57Z - **Generated By:** llms-full.php (dynamic generator) - **Database:** MySQL - **PHP Version:** 8.1.34
