Highly strengthened mechanical, morphological, IR vibrational and optical properties of rationally tailored wheat starchchitosan blends crosslinked with dual UV/acetic acid system for sustainable green packaging
Through this study, wheat starch/chitosan composite (SCB) films were successfully developed via a UV/acetic acid-assisted solution?casting approach with varying chitosan ratios. Tensile testing shows that stress at break remains nearly unchanged at lower chitosan content (1030?wt%) but increases abruptly beyond 30?wt%, reaching an optimum value at 50?wt% due to intensified hydrogen bonding and cross-linking between chitosan NH?? and starch OH? groups. Strain at break follows a similar trend, with markedly elevated elongation and elasticity. Youngs modulus exhibits the highest rigidity at 50?wt%, while stiffness decreases thereafter, consistent with enhanced elastic deformation. Morphological analysis reveals that chitosan incorporation transforms starch films from brittle, cracked surfaces to densely compact structures with fewer pore defects, resulting in superior adhesion and integrity. UVvis results show improved UV shielding, higher transparency, and tunable absorption, while FTIR analysis confirms only physical interactions with no new bonds formed between the components. Overall, chitosan incorporation significantly fortifies the SCB films by improving mechanical strength, structural stability, and optical performance, extending their application as green, multifunctional materials for sustainable packaging, coatings, and wastewater treatment. 2026 The Authors.

Highly Surface Active Anisotropic Silver Nanoparticles as Antimicrobial Agent Against Human Pathogens, Mycobacterium smegmatis and Candida albicans
Rapid synthesis of anisotropic silver nanoparticles via cost-effective, non-hazardous, and eco-friendly methods using naturally available gums are of greater significance as their chemical synthesis is associated with high toxicity. This study aims to synthesize highly surface-active anisotropic silver nanoparticles and evaluate their antimicrobial efficacy against human pathogens, Mycobacterium smegmatis and Candida albicans. Anisotropic silver nanoparticles were synthesized using silver nitrate as the metal precursor and gum arabic as the template. The synthesized silver nanoparticles were characterized by UV-visible spectroscopy, fourier transformation infra-red (FTIR) spectroscopy, dynamic light scattering (DLS) analysis, high-resolution transmission electron microscopy and selected area electron diffraction (HRTEM-SAED) analysis and thermogravimetric analysis (TGA). TEM analysis showed the anisotropy and monodispersed nature of silver nanoparticles with an average size of less than 20 nm. The antibacterial and antifungal properties of the anisotropic silver nanoparticles were also studied keeping rifampicin and fluconazole as the reference. The minimum inhibitory concentration (MIC) was found to be 1 mM silver nanoparticles for both M. smegmatis and C. albicans. Synthesized anisotropic silver nanoparticles can be used as an alternative to antibiotics to treat the infections caused by M. smegmatis and C. albicans. Further, the effect of silver nanoparticles on haemolytic activity was also studied. 2021 Wiley-VCH GmbH -
Hijab row verdict in India: A sentimental analysis of user responses on Facebook
The hijab controversy, a hot topic in India since January 2022, emerged from a clash between students and college authorities in Karnataka, a state in India. The dispute made its way to Karnatakas High Court, which, on 15 March 2022, ruled that the hijab was not mandatory for religious practices. This decision stirred widespread debates, especially on social media platforms like Facebook. This study is focused on user reactions in The Times of India Dailys official Facebook page, employing sentiment analysis to decipher public emotions, attitudes, and opinions. Nearly 200 comments posted on the verdict day were analyzed, utilizing the routine activity theory (RAT), spiral of silence theory, and online disinhibition effect. The research introduced a unique model, RAT+A, to enhance analysis. As a significant platform for public discourse, Facebook played a crucial role in capturing diverse societal sentiments and reactions regarding this social issue. 2025, First Monday.

Hindu nationalism and media violence in news discourses in India
The mainstream media and communication discourses in India in the present times engender media violence embedded in the dominant productions of Hinduism together with aspirations for neoliberal development. The media violence engenders indigenous forms of racism and colonialism. This article attempts to examine the nature of these productions through critical theories of postcoloniality and decolonial approaches put into conversation with theories of journalism. Through the examination of the instances of selective silencing of journalistic voices, and erasures embedded within the journalistic practices, this article argues for critical theories of press freedom. The productions of racial superiority and internal colonialism in India only begin to make sense when read together with the interplays of religion, class, caste, and global reach of the privileged sections of Indian society, namely the civil society. Against the backdrop of the historical role of the press in India in freedom struggle against colonial rule, the history of press censorship after independence, the civil society voices that are amplified in the neoliberal restructuring of news media, and the Dalit movements that expose the Brahminical dominance in the imaginary of the Indian culture, the meanings of race and coloniality in India unfold. 2020 National Communication Association. -
Histopathological and Toxicological Studies on Zebra Fish Using White-Fruited and Green-Fruited Varieties of Momordica charantia
Momordica charantia is well known for its medicinal properties. It has exhibited various pharmacological activities, such as antidiabetic, anti-inflammatory, and antimicrobial activities. Although this plant is used worldwide as a vegetable and medicinal ingredient in herbal medicines, its toxicity studies have not been conducted to date. This study attempts to understand its toxicity. The present study examined the activity of two enzymes, acetylcholinesterase and succinate dehydrogenase, as well as histopathological variations in the liver, intestine, and gills of zebrafish. The results of the acetylcholinesterase assay showed that the concentrations of 40 mg/L and 60 mg/L of the four extracts (leaf and fruit extracts of both varieties) exhibited increased enzyme activity. Interestingly, the leaves of the green fruit variety at a concentration of 60 mg/L showed the highest activity, with a value of 2.824 0.0682 micromoles/min compared to the control value of 1.8347 0.0046 micromoles/min. On the other hand, the succinate dehydrogenase assay revealed that the concentrations of 40 mg/L and 60 mg/L of the extracts decreased the enzyme activity. The highest inhibition was observed in the concentration of 60 mg/L of the leaves of the white-fruited variety and the green-fruited variety, with values of 1.884 0.0482 micromoles/min compared to the control value of 2.747 0.0046 micromoles/min. The studies on histopathological changes also demonstrated abnormalities in the brain, liver, intestine, and gills of zebrafish after the exposure to the extracts of M. charantia. The severity of the damage varied from low to high concentraions. In general, this study sheds light on the safety profile of Momordica charantia and highlights its potential toxicity in animal models. The findings suggest that more research is needed to fully understand the toxicity of this plant and its implications for human use. 2024 Jobi Xavier et al. -
History of gestational diabetes mellitus, self-efficacy and coping in postpartum women: A pilot study
The present study investigates whether the history of gestational diabetes mellitus (GDM) influences self-efficacy and coping among postpartum women. Purposive sampling technique was used to collect data from 100 postpartum women, 50 with a history of GDM and 50 without. The General Perceived Self-Efficacy Scale was used to measure the self-efficacy of the participants. The Brief COPE developed by Carver was used to measure coping. A Mann-Whitney U-test showed postpartum women with a history of GDM are higher in self-efficacy and coping than those without such a history. Even though self-efficacy showed a relationship to coping, the two groups differed in the use of coping strategies. 2018 by the Research Institute of Asian Women, Sookmyung Women's University.

HIV-related stigma as a mediator between perceived social support and reasons for non-disclosure of self-HIV status among children and adolescents living with HIV
Children and adolescents living with HIV face complex decisions about disclosing their HIV status, influenced by social, emotional and contextual factors, including perceived support and experiences of stigma. This study examined the relationship between perceived social support, HIV-related stigma and motivations for non-disclosure, and assessed whether stigma mediates the link between social support and non-disclosure among young people living with HIV. A cross-sectional study was conducted with 90 participants aged 1018 years receiving antiretroviral therapy at a tertiary hospital in northern India. Participants completed standardized measures of perceived social support, HIV-related stigma and non-disclosure motivations. Higher social support was associated with lower stigma, and greater stigma predicted stronger non-disclosure motivation. Mediation analysis showed a significant indirect effect of social support on non-disclosure through stigma, indicating partial mediation. Findings underscore the central role of stigma in disclosure decision-making. Interventions that enhance supportive relationships and reduce stigmatizing attitudes in families, schools and healthcare settings may promote healthier coping and developmentally appropriate disclosure. 2026 Informa UK Limited, trading as Taylor & Francis Group. -
HMOSHSSA: a novel framework for solving simultaneous clustering and feature selection problems
In real-life scenarios, information about the number of clusters is unknown. Due to this, clustering algorithms are unable to generate the valuable partitions. Beside this, the appropriate and optimal number of features is also required to produce the good quality clusters. The selection of optimal number of clusters and feature is a challenging task in the clustering. To resolve these problems, an automatic multi-objective-based clustering approach called HMOSHSSA is proposed in this paper. In HMOSHSSA, the spotted hyena and salp swarm algorithms are hybridized to obtain a better trade-off between these algorithms intensification and diversification capabilities. Two novel concepts for encoding and threshold setting are incorporated in the HMOSHSSA. The encoding scheme is used to choose the optimal number of clusters and features during the optimization process. The variance of dataset is used for setting the threshold values for both clusters and features. A novel fitness function is proposed to improve the optimization process. The suggested algorithms performance is evaluated using eight well-known real-world datasets. The statistical significance of HMOSHSSA is measured through t-tests. Results reveal that the proposed approach is able to detect the optimal number of clusters and features from a given dataset without user intervention. This approach is also deployed for solving microarray data analysis and image segmentation problems. HMOSHSSA outperformed the other considered algorithms in terms of performance measures.

Homestays as agents for responsible tourism: A comprehensive case study
The significance of implementing sustainable tourism practices has grown in light of the challenges of climate change and the diminishing availability of resources. Responsible tourism practices prioritize proactive engagement over mere adherence to sustainable practices. Therefore, the importance of responsibility cannot be overstated with the recovery and conservation efforts within the tourism sector. Responsibility should extend to the guests and encompass the environment, staff, and residents. Therefore, the present study aims to examine the potential for homestays to implement responsible tourist practices and maintain resilience. To accomplish the study's objective, an interview was conducted with a homestay owner in Shimla and Ratnari. Based on the author's understanding and the available literature on responsible tourism, there appears to be a dearth of studies about applying responsible tourism principles within the context of homestays. Therefore, the present study is of significant importance. 2024, IGI Global. All rights reserved. -
Homomorphic DNA Security in IoT Edge Data
The Internet of Things (IoT) based intelligent medical system possesses sensitive and private patient data. Most data relates to the patient's medical records and highly sensitive information. For this reason, safety and confidentiality of information are crucial. The preservation of patient privacy when sharing medical data is the primary concern of this study. Due to their excellent performance, biological notations based on deoxyribonucleic acid (DNA) are becoming increasingly admired for guaranteeing encryption and image protection. This paper proposes lightweight homomorphic with DNA-based medical image encryption (HDNA_MIE) for heterogeneous IoT in edge computing. The proposed approach contains two steps: In the first step, the secure DNA keys are generated using lightweight operations such as shifting and Josephus ring-based permutation (JRP). In the second step, the lightweight homomorphic cryptographic algorithm with DNA sequence-based encryption algorithm is suggested for secure encryption. The suggested strategy is evaluated using computational time and statistical analysis with several measures to determine its efficacy. The experimental findings of the proposed strategy exhibited a high level of security and a noticeable enhancement in the Number of Pixels Change Rate (NPCR), Unified Average Changing Intensity (UACI) and encryption processing time. The experiment outcomes demonstrate that our technique may be applied to highly confidential image encryption. 2024, Iquz Galaxy Publisher. All rights reserved. -

Hormonal-mediated Cicer arietinum L. leaf extract-assisted synthesis of a ternary g-C3N4/ZrTiO4/V2O5 nanocomposite for photocatalytic remediation of organic pollutants
A novel green synthesis approach was developed for the fabrication of a g-C3N4/ZrTiO4/V2O5 nanocomposite (NC) using a hormone-treated plant extract as a biogenic reducing and stabilizing agent. The hormone-assisted synthesis had a significant influence on the physical, chemical, and morphological properties of the nanocomposite compared to the control route. The obtained NCs, confirmed by XRD, FTIR, UV-vis, SEM, and EDX analyses, exhibited enhanced crystallinity, a reduced band gap, and a distinct morphological transformation from nanorods to nanocubic structures. Elemental composition analysis confirmed the successful integration of Zr, Ti, and V components, improving the photocatalytic performance of the material. The hormone-mediated g-C3N4/ZrTiO4/V2O5 NC achieved an 89.14% degradation efficiency of Rose Bengal dye, maintaining its activity over three successive cycles without notable loss of performance. Furthermore, the photocatalyst efficiently converted degradation intermediates, such as benzyl alcohols, into valuable substituted benzaldehyde derivatives with yields ranging from 75% to 92%, demonstrating sustained catalytic stability over four consecutive cycles. These findings highlight the potential of hormone-assisted green synthesis as a promising and sustainable approach for designing advanced photocatalytic nanomaterials.

Horror and the body: Corporeal transformations and postcolonial motifs in Satyajit Rays Neel Atonko and Khagam
The genre of postcolonial Gothic questions imperial power structures and exposes the anxiety and violence embedded in colonization. It combines imperial Gothic tropes with regional narratives. This article analyses two short stories by Satyajit Ray, Neel Atonko (The Indigo Terror) and Khagam, examining how Bengali horror fiction uses and subverts Gothic tropes through corporeal transformation. It discusses the babu/bhadralok (westernized Indian men) culture from a postcolonial perspective, and argues that the supernatural transformations depicted in the stories indicate the instability of colonial identity. The human body becomes the primary site through which colonial oppression and resistance are portrayed. Using Homi Bhabhas concept of mimicry, Julia Kristevas discussion of the abject, and Xavier Aldana Reyess analysis of body gothic, this article examines how the stories critique the violence of colonial ideology through postcolonial motifs that situate the white man in a powerless position, thereby challenging established power structures of imperial Gothic. 2026 Informa UK Limited, trading as Taylor & Francis Group.
