Thermal and solutal stratified Heimanz flow of AA7072-deionized water over a wedge in the presence of bioconvection
The bioconvective Heimanz flow of nanofluid across a wedge with thermal stratification is analyzed in this article. The wedges are often seen in glider aircraft, rocket climbing frames, etc. The nanofluid considered in this study is composed of aluminum alloys of AA7072 and deionized water. The AA7072 alloys are specially manufactured materials composed of Aluminum and Zinc in the ratio of (Formula presented.) along with metals like silicon, ferrous, and copper so that they possess enhanced heat transfer features. The mathematical model is formed using the modified Buongiornos model that includes the discussions related to slip mechanisms and volumetric analysis in terms of the weight of the nanoparticle. The model is in the form of partial differential equations and is later converted to ordinary differential equations with the assistance of similarity transformation. This set of equations is solved by the Differential Transformation Method (DTM) and the outcomes are discussed through graphs.,. 2024 Taylor & Francis Group, LLC. -
Analytical study of triple diffusive convection in a bi-viscous Bingham fluid layer using Ginzburg-Landau model
In this paper, considering bi-viscous Bingham as the base fluid, we study the thermophysical-properties (such as density, specific heat, thermal conductivity, thermal diffusivity, and thermal expansion) with different combinations of salts among NaCl, KCl, CaCl2, and NaCl2 of triple diffusive convection in a bi-viscous Bingham fluid layer with heat as one of the diffusing components. A weakly non-linear case is formulated to facilitate a solution to the problem using a series solution Ginzburg-Landau model. With regard to single, double, and triple diffusive convection, the tables are made to record the actual values of thermophysical-properties together with the critical Rayleigh-number for each combination of aqueous-salt solutions. This computation calculates the mean Nusselt and Sherwood numbers to quantify the systems heat- and mass-transfers for various aqueous-solutions. The effect of the bi-viscous Bingham fluid parameter, for small and large values, for different aqueous-solutions, in single, double, and triple diffusive convection has been captured via 2-dimensional (2D) and 3-dimensional (3D) figures and the results are recorded and compared. The investigation reveals that the heat- and mass-transfers increase with an increase or decrease in the bi-viscous Bingham fluid parameter, which in turn depends on the values of (Formula presented.) and (Formula presented.) The results confirm that the heat- and mass-transfers are least for the combination of KCl with CaCl2 and maximum for the combination of NaCl with other salts. 2024 Taylor & Francis Group, LLC. -
Magnetohydrodynamic flow of two immiscible hybrid nanofluids between two rotating disks
The two-layer model of the magnetohydrodynamic flow of hybrid nanofluid (HNF) between two disks of the same radii is analyzed in this study. The base fluids of both the hybrid nanofluids are immiscible so that these two fluids form an interfacial layer making the study more unique and innovative. The heat source/sink with viscous dissipation effect on energy equation is discussed. The governing equation is in the form of PDEs that are later reduced to ODEs with the help of the Von Karman transformation. The resulting ODEs are solved using the RK method and the results are interpreted graphically. In addition to temperature and concentration gradient, the radial, tangential and axial velocities for different parameters are studied. The results indicate that the physical ratios such as viscosity and thermal conductivity ratios can improve the fluid motion and temperature even in the presence of magnetic field. Also, the ratio of stretching rate produced by the rotation of disk can effectively control the fluid motion. The two fluid flow between two rotating disk forms an interfacial layer between the fluids results in the increment of heat transfer rate which finds application in the field such as heat ex-changer equipment, Cryogenic systems, electronic appliances, and solar collectors. 2024 Taylor & Francis Group, LLC. -
Heat transfer optimisation through viscous ternary nanofluid flow over a stretching/shrinking thin needle
The current investigation interprets the flow and the thermal characteristics of the ternary nanofluid composed of MoS 2, ZnO, and SiO 2 spherical nanoparticles and water. The resulting nanofluid is (Formula presented.) where (Formula presented.) act as the base fluid which help in the flow and the nanoparticles contribute to enhancing the heat conductivity. The flow is assumed to occur across a thin needle whose surface is maintained at a higher temperature than the surroundings. The mathematical model is framed by incorporating radiation introduced by Rosseland in terms of partial differential equations (PDE). This system of equations governs the flow and thermal properties of fluid which are converted to a system of ordinary differential equations (ODE). The major outcomes of the study indicated that the increase in the amount of molybdenum disulfide enhanced the heat conducted by the nanofluid whereas it reduced the flow speed. The positive values of the heat source/sink parameter caused the heat conduction of the nanofluid to go high. 2023 The Author(s). Published with license by Taylor & Francis Group, LLC. -
Season of Hate and Intolerance: Revisiting Ambedkar and Periyars Path to Social Justice
While India celebrates 75 years of being an independent republic, the rise in hate crimes fueled by caste and religious prejudices poses a serious threat to the constitutional values and secular fabric of the nation. Despite the constitutional safeguards, Dalits and religious minorities continue to face discrimination, violence and social exclusion, making social justice an elusive goal. Dr. B. R. Ambedkar and E. V. Ramasamy Periyar (hereafter referred to Periyar) promoted the idea of self-respect, arguing that it is crucial for social cohesion and the realization of social justice. Drawing on recent cases of hate crimes reported in Tamil Nadu, this study examines the complexities of caste dynamics and the emergence of religious intolerance in contemporary times. It argues that rejuvenating the concept of self-respect offers a transformative pathway toward achieving social justice. It also offers a few constructive possibilities to strengthen the application of self-respect in the pursuit of social justice. It concludes by highlighting the scope for a scholarly engagement on the idea of self-respect and exploring it as a broader, emancipatory framework for social justice beyond the socio-political context of Tamil Nadu. , Copyright Taylor & Francis Group, LLC. -
The effect of an environmental education program based on empathy and reflective thinking on preadolescents environmental values and knowledge
As a remedial measure to human-induced climate change, it is imperative to develop intrinsic altruistic values and adequate knowledge of environmental phenomena and behavior to act in favor of the environment. The study aims to assess the effect of an Environmental Education Program (EEP) based on empathy, reflective thinking, and information on preadolescents environmental values and knowledge. For that, a non-equivalent control group design was used. Data collection was done through questionnaires, checklists, and participant thought diaries. Forty-six students (eleven-to-twelve-year-old children) selected through purposive sampling from the sixth standard of two semi-urban schools in Kerala, India, constituted the sample. In the intervention, empathy was manipulated through stories and empathy exercises, reflective thinking through thought diaries, and information on environmental phenomena, issues, and the effect of human actions through stories and knowledge exercises. Empathy, reflective thinking, and information manipulations positively influenced the participants environmental values and knowledge, and the effect manifested in cognitive, affective, and conative dimensions. The study has implications for conducting Environmental Education indoors effectively by integrating affective, cognitive, and metacognitive approaches. Empathy stories can be utilized to address various environmental phenomena and issues. Reflective thinking on environmental phenomena and issues can be applied to teach appropriate environmental behaviors. 2024 Informa UK Limited, trading as Taylor & Francis Group. -
Alcohol and social drinking norms as a catalyst between tourist motivation and tourist satisfaction
This article aims to understand the influence of alcohol availability, ethnicity, anti-alcohol enforcement at tourist destinations, social norms of drinking among tourists and relationships with tourist motivation and tourist satisfaction. A cross-cultural empirical study was conducted using purposive sampling of 476 tourists with partial least squaresstructural equation modelling (PLS-SEM). The results suggest that tourists perceive social norms of drinking and the availability of alcohol at destinations, when coupled with ethnicity, influence the dynamics of the relationship between tourist motivation and tourist satisfaction. The availability of alcohol at tourist destinations alone does not have any relationship either with tourist motivation or with tourist satisfaction. Based on the findings, tourist service providers and facilitators can design drinkscapes specifically based on tourists ethnic background and social norms of drinking to rejuvenate tourist destinations and make them more attractive and inclusive. As the current research considers the tourists ethnic background from a general perspective, future research may investigate the impact of subcultures to understand how ethnicity effects drinkscapes and tourist behaviours. 2025 Informa UK Limited, trading as Taylor & Francis Group. -

Towards resilience: navigating local knowledge in flood risk management strategies in Majuli Island, Assam
Scientific knowledge of climate change and its latent effects is important. But it often lacks the expertise of local communities. This paper emphasises the importance of understanding local knowledge within the dynamics of vulnerability and resilience. It also offers insights into the applicability of these knowledge systems, providing valuable lessons and challenges on local knowledge in flood risk management. The study was conducted within a qualitative framework, utilising a case study design, in Majuli Island. Data were collected through 20 key informant interviews. Findings reveal that the diverse dimensions of local knowledge among Indigenous communities strengthen mitigation, coping, and adaptation strategies, enabling them to endure recurring floods. The evidence presented can guide government and non-governmental organisations (NGOs) in Majuli in integrating local knowledge into their interventions. By documenting and critically analysing existing practices, this paper adds to the growing literature on local knowledge in disaster research and practice. 2026 Informa UK Limited, trading as Taylor & Francis Group. -
Exploring media representation and female-to-male transgender journeys in India: a redefining of masculinity
This paper argues that the invisibility of trans men in Indian media is not just a consequence of societal prejudice but a reflection of deeper structural biases within the discourse of masculinity itself. By examining both historical contexts and specific media representations, it demonstrates how trans men's experiences challenge the conventional association between masculinity and power, calling for more inclusive media portrayals. Psychotherapists and transgender studies researchers assert that gender is both distinctive and biological in origin while advocating for gender transitions to be supported through social change and queer perspectives. Despite increasing media exposure, many remain unfamiliar with transgender issues, leading to persistent misrepresentations. Trans men, unlike male-to-female transgender individuals, face unique stigma and often remain invisible in media narratives and public discourse. This paper utilises secondary data, textual analysis, and media analysis to examine the evolution of trans men in India and the media's role in shaping societal perceptions of trans-masculinity. It emphasises the need for improved media representation to enhance the visibility of trans men and to foster greater societal support and understanding within the broader transgender movement in India. 2025 Informa UK Limited, trading as Taylor & Francis Group. -
Does AI matter in marketing? Unveiling the role of AI-driven marketing in quick grocery
This study explores the impact of AI-driven marketing techniques on consumer attitudes and purchase intentions in the growing Q-grocery sector. The increasing use of AI in digital marketing presents opportunities to examine its influence on consumer decision-making, yet its specific impact within grocery shopping apps remains underexplored.Using theStimulus-Organism-Response (SOR) model, this study examines how AI-driven marketing techniques, namely personalisation, smart search, and dynamic pricing, influence consumer behaviour. Data were collected from 327 respondents through an online survey targeting users of Q-grocery shopping apps in India. Structural Equation Modelling (SEM) was used to test the relationships between AI marketing techniques and consumer purchase intentions.Findings reveal that personalisation and smart search have a significant positive impact on purchase intention, while dynamic pricing showed no significant effect. Additionally, consumer hedonic and utilitarian attitudes were found to mediate the relationship between AI marketing techniques and purchase intention. By connecting AI marketing strategies to purchase intention and consumer attitudes, this research adds a new perspective on how digital tools can influence consumer decision-making. These findings hold broader implications for omnichannel environments, where consistency in AI-enabled experiences across digital and physical touchpoints is critical for sustaining engagement. It also provides valuable insights for marketers seeking to enhance engagement and increase sales through targeted AI-driven strategies. 2025 Informa UK Limited, trading as Taylor & Francis Group. -
Banana peels as a cost effective substrate for fungal chitosan synthesis: optimisation and characterisation
Massive accumulation of unprocessed banana peels enthralls sustainable issues as they are eventually dumped as landfills leading to emission of obnoxious gasses. To avoid these persisting challenges the present study shims lights on chitosan production from the characterised fungal strain using banana peel hydrolysate as an effective medium. Substantial amount of carbohydrate in banana peels serves as a potential solution for fungal chitosan production in a view to attain a circular bioeconomy and repurposed for synthesis of beneficial products in a cost effective manner. Presence of fermentable sugars in banana peels qualifies them as a feasible substrate which could be exploited for scaling up of fungal chitosan synthesis. Screened isolate was subjected to statistical optimisation using formulated medium to elucidate the influential factors that had significant effect on chitosan production. The harvested chitosan biomass was characterised through standardised techniques and evaluated for further studies. Statistical optimisation reveals that ammonium nitrate (5 g/L), pH (6) and incubation time (144 hrs) were the three PBD variables that had a greater influence on fungal chitosan yield. The validated developed model exhibited maximum yield of 200 mg/L, a 4.4 fold increase than unoptimised medium (45 mg/L). These findings emphasise the fermentative synthesis of chitosan through valorisation of banana peel prop up a complementary approach in concomitant with preserving renewable resources and bioproduct formation. 2023 Informa UK Limited, trading as Taylor & Francis Group. -
Constructing healing narratives: a culturally grounded intervention for tribal women survivors of intimate partner violence in India
Intimate partner violence (IPV) profoundly disrupts womens sense of self, relationships, and belonging, with particularly severe consequencesfor marginalized and indigenous women. This paper reports findingsfrom a pilot study on the development and preliminary implementationof a culturally grounded mental health intervention for tribal women survivors of IPV in Wayanad, Kerala, India. The intervention was developed in response to the limited cultural relevance of main stream trauma-focused models in indigenous contexts and was informed by constructivist, psychodynamic, narrative, and cognitive-behavioural principles. Ten tribal women aged 1850 participated in a five-session group-based programme that integrated indigenous cultural expressionssuch as folk songs, rhythmic movement, clayart, and storytellingwith therapeutic processes aimed at meaning-making, emotional regulation, and identity reconstruction. Sessions emphasized symbolic expression and collective reflection, enabling participants to externalize traumatic experiences and renegotiate personal narratives within a culturally familiar and emotionally safe space. Qualitative reflections indicated notable shifts from shame, self-blame, silence, and social isolation toward emerging narratives of resilience, agency, and connection. Participants reported enhanced emotional expression, strengthened coping strategies, and increased community support. Overall, the findings underscore the feasibility and cultural relevance of art-based, constructivist interventions for tribal women survivors of IPV. Future research should employ larger samples and mixed-methods designs to assess long-term outcomes and adaptability across diversetribal contexts. 2025 Informa UK Limited, trading as Taylor & Francis Group. -
Unpaid care labour in India: a feminist and intersectional analysis of lived experiences
The article offers an expanded feminist analysis of Unpaid Care Labour (UCL) by integrating a personal narrative style grounded in feminist theory, intersectionality, and ecological economics, drawing on qualitative data from five focus group discussions conducted in India. Through participant narratives, the article unpacks themes such as time poverty and the double burden, health implications and emotional well-being , economic dependency and intersectional inequities, cultural policing and social norms, and transformative pathways and policy gaps. While participants articulated the strain of time poverty and the double burden of juggling paid and unpaid work, the intensity and coping mechanisms varied markedly by caste and class context. Lower-caste women faced compounded strain due to limited support and infrastructure; in contrast, upper-caste women experienced emotional stress from societal expectations. The study foregrounds how caste-based hierarchies, economic precarity, and patriarchal norms intersect to shape womens caregiving realities in differentiated yet overlapping ways. It argues that public policy must move beyond tokenistic acknowledgements and instead invest in care infrastructure, legal protections for domestic workers, and campaigns that shift cultural perceptions of care as a shared societal responsibility. Recognizing, redistributing, and reducing UCL is essential to fostering gender justice and inclusive development. 2025 Informa UK Limited, trading as Taylor & Francis Group. -
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. -
Mechanical and moisture resistance properties of flax and jute fiber embedded epoxy composites for lightweight structural applications
Natural fiber-based materials are increasingly used as substitutes for traditional materials in structural applications. This research evaluated the mechanical and moisture resistance characteristics of unidirectionally oriented Flax and Jute fiber-embedded Epoxy Composites (FJEC) for lightweight structural applications. The inclusion of nano clay in the natural laminates creates more energy-absorbing sites, which improves the ability to withstand impact forces compared to FJEC. The material strength of nano clay-infused hybrid composite attained 94.46 MPa, 98.44 MPa, and 92 KJ/m2 tensile, flexural and impact strength. The consequences of water absorption and humidity exposure to the materials revealed that nano clay helps to reduce the diffusion of water into the surface of the laminate. The nano clay-infused hybrid composite is subjected to Freeze-Thaw (Fz-Tw) cycling under both partial and complete immersion scenarios to analyze the durability and resilience of the composite. The performance loss in nano-clay-infused laminate is caused due to the prolonged exposure to water and thermal stress. The damage factor for a partially and completely immersed hybrid material is 1.2% and 2.2%, respectively. These findings highlighted the need for considering environmental conditions while designing and utilizing fiber incorporated materials in various applications. 2026 Informa UK Limited, trading as Taylor & Francis Group. -
Therapeutic romanticism: Khalil Gibrans journey from rebellion to spiritual healing
This article argues that Khalil Gibrans Romanticism functions not merely as literary expression but as a poetic mechanism for processing trauma, cultivating resilience, and fostering relational awareness, especially in contexts of exile and existential fragmentation. To operationalize this reading, the study employs a literary micro-model: Van der Kolk and Fisleriss Dissociation and the Fragmentary Nature of Traumatic Memories used to map The Madman (1918) as the ruptured phase, where fragmentation, irony, and self-estrangement externalize pain; while Seligmans PERMA model frames The Prophet (1923) as the integrative phase, where meaning, relationships, and transcendence articulate universalist healing. By juxtaposing alienation and flourishing, the analysis highlights Gibrans movement from rebellion to harmony, revealing poetrys potential as a therapeutic medium for personal and collective crises. 2025 National Association for Poetry Therapy. -
