Fabrics of Power: Cutting Through the Noise in the Classroom
The hijab, purdah and veil though differently named constitute a continuum of meanings shaped by social, cultural and personal contexts. A womans decision to adopt or reject these garments situates her within a shifting spectrum of religious expression and secular alternatives. The volatility of these meanings renders the garments vulnerable to political appropriation, transforming them into contested symbols that are difficult to address pedagogically, therefore becoming a fabric of power. The hijab controversy that unfolded in Karnatakas educational institutions in early 2022 sharpened these complexities, prompting extensive public commentary on the purpose of education, the responsibilities of institutions, and the rhetorics of liberty, secularism, nation and religion. This article examines these commentarial responses ranging from editorials to columns in Kannada and the English media while reflecting on the parallel experience of teaching concepts such as liberty, dissent, secularism and religion during the period of unrest. In doing so, it foregrounds the paradox inherent in the politics of teaching literature, the framing of literature as political, and the pedagogical negotiations required when instruction unfolds within a charged and highly politicised atmosphere. 2025, Unisa Press.

Quantum computational, solvation and in-silico biological studies of a potential anti-cancer thiophene derivative
Heterocyclic molecules display a wide spectrum of properties that span both material and biological domains. Material properties stem from their interactions in the bulk, where a large number of molecules of the same type get together resulting in an enhancement of properties. However, biological properties emanate from the interaction of a single or a few molecules with a biologically functional macromolecule. Computational tools offer a particularly useful way of theoretically studying molecules to arrive at a conclusion regarding such properties, even though they may vary when experimentally evaluated. This study concerns itself with the theoretical investigation comprising density functional theory calculations, topological analyses and in-silico biological evaluation of a thiophene compound, i.e. the title compound. Density functional theory was used to compute properties of the title molecule and their variations in unsolvated and solvated phases using Gaussian 09. The molecule in solvent phases encompassing organic polar protic, organic polar aprotic and inorganic polar protic nature have been subjected to theoretical investigations. The suitability of the molecule for deployment as a modern optical material is examined with positive results. Topological characteristics of the molecule were evaluated using Multiwfn 3.8 to examine electron density distribution and the possible resulting covalent, non-covalent and weak interactions because of such distribution. The potency of the molecule towards brain cancer was evaluated by molecular docking with Auto Dock Tools against two brain cancer protein targets 6ETJ and 6YPE with a good docking score of ?6.63 and ?6.21 kcal mol?1 respectively and the resulting interactions visualized and its pharmacokinetic properties obtained using online tools. 2024 Elsevier B.V. -

Assessing Land Use Transformation in Kanhangad Town: A Special Emphasis on Wetland Ecosystems
Kerala, renowned for its lush landscapes, is facing environmental challenges due to rapid urbanization, particularly in Kanhangad. This area, notable for its unique wetland ecosystem crucial for biodiversity and human livelihoods, is experiencing a conflict between residential development and wetland conservation. A comprehensive study in Kanhangad, employing diverse data sources such as open-source data, Google Earth Satellite Imagery, OpenStreetMap, and tools like ArcGIS, provides a detailed analysis of land use and its environmental impacts. The study combines digital data analysis with physical surveys to understand the ecological and developmental status comprehensively. The study reveals a dominant trend in Kanhangad's land use, with residential areas comprising 52% of the total land, mostly large, detached single-family homes. This reflects a societal shift towards viewing homes as status symbols, contributing to natural resource depletion. The research underscores the need for sustainable, low-cost housing, suggesting vertical housing as a potential solution to balance residential demands with environmental conservation. Kanhangad's wetlands, essential for local biodiversity and livelihoods, face threats from urban development and infrastructural expansion. The study shows a drastic reduction in wetland area, from 12.9 km in 2004-05 to just 1.66 km by 2020-21, indicating severe ecological degradation. Despite the Kerala Conservation of Paddy land and Wetland Act of 2008, which aims to protect these ecosystems, its limited effectiveness is evident from the ongoing depletion of wetlands. This situation calls for stricter enforcement of environmental regulations and greater public involvement in conservation efforts. Furthermore, the research examines the Kerala Paddy and Wetland Conservation Act-2008, analysing its role and effectiveness in local environmental governance. The Act, focusing on prohibiting wetland and paddy land conversion, is vital for regional conservation. However, gaps in its implementation are highlighted, especially considering the exacerbation of the 2018 and 2019 Kerala floods due to land conversion practices. The study emphasizes the urgent need for more robust environmental protection measures. 2024 by authors. All rights reserved. -
Impact of ESG Index on the Stock Return: Empirical Evidence from CRIP Sector
In modern times, investment decisions are significantly influenced by a range of metrics. One widely embraced investment strategy in both developed and developing economies is investment through analysing Environmental, Social Responsibility, and Governance (ESG) factors. Investors rely on ESG scores as a valuable resource to pinpoint companies that are more likely to maintain their growth trajectory while reducing the possibility of encountering negative occurrences such as legal complications, controversies, and unfavourable public attention. This, in turn, facilitates more effective risk management and enhances returns on investment. However, the influence of ESG factors on stock returns within the Construction, Real Estate, Infrastructure, and Project (CRIP) sector is relatively limited. Consequently, the main aim of this study is to assess how ESG aspects influence the returns of stocks in companies operating in the CRIP sector. To conduct this analysis, we employed the Crisil ESG database, which provides comprehensive data on ESG metrics and stock returns. A sample containing 35 companies from the CRIP industry was meticulously chosen for investigation. To quantify the influence of ESG aspects on stock returns within the CRIP sector, a Fixed Effect Panel Regression Model was applied. The study results suggest a favourable and considerable relationship of ESG ratings on the closing stock price. Furthermore, the analysis demonstrates a large and beneficial influence of ESG ratings on stock returns. These results contain substantial implications for investors and stakeholders having a vested interest in making well-informed investment choices within the CRIP industry.

Continuum Mechanical Study of Love-Wave Propagation in Fibre-Reinforced Plate Over an Orthotropic Substrate with Interfacial Imperfection
Abstract: This paper aims to analyse the propagation of Love-type waves in a fibre-reinforced composite (FRC) over a pre-stressed orthotropic substrate. The upper fibre-reinforced layer is imperfectly bonded to the lower orthotropic half-space. The structure considered has a mechanical imperfection (MI). The purpose is to investigate the integrated effect of fibre reinforcement, initial stress, and flawed interface on the dispersion and attenuation of Love-type waves. The dispersion relation is derived analytically using the boundary condition. The phase velocity of the Love-type wave has been discussed in its typical cases: (i) in the infusion of reinforcement and absence of initial stress, (ii) in the presence of reinforcement subjected to initial stress, considering scenarios with and without the flawed coupling. The numerical computation of the analytical finding was performed and plotted using MATLAB, showing the impact of the parameters considered. It is observed that the interfacial imperfection positively influences the phase velocity of the Love-type wave in the model considered. The increase in the reinforcement parameter and the decrease in lead to attenuation in phase velocity. In engineering, fibres are considered to be oriented in two or more directions, and the study assumes only bidirectional fibres. The results highlight the combined influence of mechanical anisotropy, pre-stress, and interface quality on guided wave characteristics, offering valuable insights for the design and optimisation of layered composites, acoustic sensors, and structural health monitoring systems.

Real-Time Fabric Defect Detection Using a Lightweight YOLOv8 Model on Edge Devices
The detection of defects in fabric is a critical process for maintaining quality standards and reducing economic losses in the textile industry. Traditional inspection methods, which rely on human operators, are often slow, inconsistent, and susceptible to error. This research introduces an innovative solution that harnesses Edge AI and deep learning to facilitate real-time, on-site defect detection. We developed a highly efficient and lightweight model based on the YOLOv8 architecture, specifically tailored for deployment on resource-constrained edge devices like NVIDIA Jetson Nano or Raspberry Pi. Through a process of comprehensive literature analysis and domain expertise, a compact, high-precision model was trained on diverse fabric defect datasets. To ensure optimal performance on edge hardware, we employed advanced optimization techniques like quantization and pruning. The primary offering of the work are threefold: the making of a streamlined YOLOv8-based model for fabric defect detection, a comparative analysis of various edge inference strategies, and a proposed system architecture for real-time embedded deployment. This study effectively demonstrates the practical application of advanced AI to solve longstanding challenges in textile quality control. Future efforts will be directed towards extensive real-world operational testing and exploring localized Model Training with Federated Learning enhancement. 2025 IEEE. -

A Pathway to Better EMI Shielding Performance in Natural Rubber Through Ternary Carbonaceous Filler Systems
In the present study, we fabricated and characterized ternary hybrid fillers of conductive carbon black (CCB), carbon nanotubes (CNT), and reduced graphene oxide (RGO) reinforced natural rubber (NR) composites. The ternary filler system exhibited good filler-polymer interaction as observed from the cure characteristics and mechanical properties. We used impedance analysis to study the dielectric permittivity and associated polarization mechanisms, and the AC conductivity was fitted using the Jonsher Power law. The presence of functional groups on the ternary nanofiller surfaces caused increased filler-filler interactions, leading to the formation of an excellent conductive network. Mechanical and viscoelastic studies revealed the reinforcing effect of the CCB, CNT, and RGO fillers. The theoretical models, such as Nicolais-Narkis and Turcsanyi, were employed to predict the tensile strength. Morphological analysis confirms the homogeneous dispersion of filler in the matrix. The present system also demonstrated excellent electromagnetic interference (EMI) shielding performance, with the highest shielding effectiveness (SE) values of 37.4 and 35.3 dB at 12 GHz for the ternary composites, satisfying commercial requirements. 2026 John Wiley & Sons Ltd. -
