Efficacy of sugarcane bagasse to produce bacterial biofilm in water for fish culture
No full textThe present study has been conducted to understand the efficacy of sugarcane bagasse to produce bacterial biofilm in water. The study period was 90 days. Total Plate count (TPC) in water and substrate was estimated on nutrient agar at room temperature by spread plate method. The TPC in water was the highest (2.10 x 104 ml–1) after 45 days. The average TPC of bacteria on bagasse varied from 140.0 (15d) to 30.25 (90d) x104·g–1. The present study demonstrates that the sugarcane bagasse can produce more bacteria in water thereby the fish can effectively utilize biofilm grown on sugarcane bagasse and provision of a substrate reduces the need for artificial feed.---------------------------------------------------------------------------------------------------------Efficacy of sugarcane bagasse to produce bacterial biofilm in water for fish culture M.V.

Registration and Segmentation of Multimodality Images for Post Processing of Skeleton in Preclinical Oncology Studies
No full textAdvancements in medical imaging techniques provide biomedical researchers with quality anatomical and functional information inside preclinical subjects in the fields of cancer, osteopathic, cardiovascular, and neurodegenerative research. The throughput of the preclinical imaging studies is a critical factor which determines the pace of small animal medical research. The time involved in manual analysis of large amount of imaging data prior to data interpretation by the researcher, limits the number of studies in a time frame.
In the proposed solution, an automated image segmentation method was used to segment individual vertebrae in mice. Individual vertebrae of MOBY atlas were manually segmented and registered to the CT data. The PET activity for L1-L5 vertebrae was measured by applying the CT registered atlas vertebrae ROI. The algorithm was tested on three datasets from a PET/CT bone metastasis study using 18F-NaF radiotracer.
The algorithm was found to reduce the analysis time threefold with a potential to further reduce the automated analysis time by use of computer system with better specification to run the algorithm. The manual analysis value can vary each time the analysis is performed and is dependent on the individual performing the analysis. Also the error percent was recorded and showed an increasing trend as the analysis moves down the spine from skull to caudal vertebrae. This method can be applied to segment the rest of the bone in the CT data and act as the starting point for the registration of the soft tissues

Integrating toda embroidery with pre-consumer textile waste: A sustainable approach to fashion production and cultural preservation
No full textThis research aims to develop a systematic approach for reducing pre-consumer textile waste by integrating traditional Toda embroidery techniques into garment repair. This study focuses on promoting environmental sustainability while preserving indigenous cultural heritage. Drawing parallels with the Japanese Kintsugi concept, which transforms broken ceramics into aesthetic enhancements, this study proposes a structured method to elevate defective textiles through Indigenous craftsmanship. The Sustainable Textile Repair through Indigenous Embroidery (STRIE) Method consists of four phases, i) Defect Assessment ii) Artisan Engagement iii) Repair Execution and iv) Quality Assurance. This framework extends garment lifespans, reduces environmental impact and creates sustainable economic opportunities for Toda artisans. The STRIE Method presents a scalable framework for sustainable textile repair, strategically aligning with four United Nations Sustainable Development Goals (SDGs 8, 11, 12, 13). This innovative strategy facilitates the conversion of textile waste into garments that carry cultural significance while promoting environmental sustainability. It adeptly fuses traditional craftsmanship with modern sustainable production techniques, creating a model that enhances both the ecological and cultural value of textile products. • Introduces a structured integration of traditional craftsmanship into modern repair. • Combines digital defect assessment with artisan training and quality assurance. • Reduces textile waste, preserves cultural heritage and supports sustainable livelihoods
The New Sociology of Childhood: Animal Representations in Leslie Marmon Silko’s Garden in the Dunes, Amazon’s Oh My Dog and Netflix’s Mughizh: A Cross-Cultural Analysis
No full textThe theory of “new sociology of childhood” and “universalism in cross-cultural psychology” highlights that children experience different childhood based on their cultural and social contexts. Children are social actors responsible for taking situations into action. Research considers children as neglected bodies in the field of children and childhood. This research paper compares Native American and Indian children’s competence as social actors, the definition of, experiences, and feelings towards animals. The objective is to show that children and animals are closely connected and that children’s childhood is based on their experiences with animals. In the children’s novel, Garden in Dunes (1999), Leslie Marmon Silko narrates the story of Indigo accompanied by Linnaeus (a monkey) and Rainbow (a parrot) which shapes the world around her. Oh My Dog (2022) and Mugzhil (2021), broadcasted on Amazon Prime and Netflix respectively, are stories based on young children who love and care for their pet dogs. Findings suggest that children’s emotions and approach towards animals are the same in both cultures but their experiences vary from one place to another
Beyond the screen: The psychological significance of ecophilia in childhood
No full textThe environmental crisis, fuelled by rapid urbanization, technology, and changing lifestyles, threatens humanity. Children's disconnection from nature negatively impacts their physical, mental, and environmental well-being, increasing their risk of psychological distress, including elevated stress levels, impaired emotional stability and cognitive function, diminished social interactions, and increased susceptibility to anxiety, depression, lower self-esteem, and reduced overall life satisfaction. Consequently, environmental risks have impact on the health and development of the children from early childhood to adolescence and then to adult life. The research article aims at diminished nature connection in children and the emergence of psychological distress. This interdisciplinary research, blending ecology and psychology, uses ecocritical lenses—biophilia (love for nature and living things), topophilia (love for particular place or environment), and ecophilia (love for nature itself) —to explore how diminished nature connection impacts children's well-being. The findings emphasize the importance of reconnecting children with nature and fostering ecospirituality for their well-being and a sustainable future. This research concludes that fostering ecophilia enhances children's cognitive function, environmental awareness, and stewardship, while also promoting ecospirituality. • Human-nature interactions are key learnings for children. • This research aims to integrate ecology and psychology fostering interdisciplinary approach
A monolithically integrated power JFET and Junction Barrier Schottky diode in 4H silicon carbide
No full textEfficiency of power management circuits depends significantly on their constituent switches and rectifiers. The demands of technology are increasingly running up against the intrinsic properties of Si based power devices. 4H-Silicon Carbide (SiC) has superior properties that make it attractive for high power applications. SiC rectifiers are already a competitive choice and SiC switches have also been commercialized recently. Junction Barrier Schottky (JBS) diodes, which combine the advantages of PN and Schottky, have higher Figure of Merit (FOM) as rectifiers. Among switches, a robust and mature process has been developed for Silicon Carbide Vertical Junction Field Effect Transistors (VJFETs), which currently gives it the highest unipolar FOM. Switches are frequently combined with anti-parallel diodes in power circuits. This thesis describes the development of a SiC-based monolithically integrated power switch and diode. Monolithic integration increases reliability and efficiency, and reduces cost. Because of their superior properties and similarities in fabrication, we chose the SiC VJFET and JBS diode as the switch and rectifier. Detailed design, fabrication and characterization of the integrated switch to block above 800 V and conduct current beyond 100 A/cm2 is explained. In this process, the first physics-based 2-D compact model is developed for reverse leakage in a JBS diode as a function of design parameters. Since the gate-channel junctions of SiC VJFETs cannot be assumed to be abrupt, an existing analytical model for Si VJFETs is extended to account for graded gate-channel junctions. Using these analytical models, design rules are developed for the VJFET and JBS diode. Finite element simulations are used to find the best anode layout of the JBS diode and optimize electric field termination in the integrated device to ensure their capability to operate at high voltage. Finally, a spin-on glass based process is developed for filling the gate trenches of the VJFET to improve long-term robustness in extreme environments. The integrated power switch developed in this thesis points to the attractions of monolithic integration in SiC power circuits. Analytical compact design equations derived here will facilitate faster and easier design of switches and rectifiers for desired circuit operation.Ph.

Status of Holocaust teaching in secondary level of education in Kerala: analysis and suggestions
No full textAbstract Holocaust education in India has been overlooked for reasons ranging from the perception of the Holocaust as a European event to the simultaneous historical occurrence of Indian Independence in the 1940s. The study aims to address the existing gap in research on Holocaust education in the South of India by analysing the status of Holocaust education in the state of Kerala and providing feasible suggestions for improvement. The Cochin Jews were the oldest Jewish settlers in India dating back to 10th century CE. The Jewish settlement in Kerala resonates with the history, architecture and cultural arts of the state. As an integral part of the state’s history, teaching Jewish history and the Holocaust is inevitable for a comprehensive understanding of the periodical development of the state. Presently, the Jewish community in Kerala is on the brink of fading into history. The purposeful teaching of the Jewish settlement and the Holocaust would protect Jewish history of the state from historical erasure. The research attempts to study the Jewish presence and Holocaust teaching within school syllabi across Kerala. The paper analyses the history textbooks of the Kerala State Council of Educational Research and Training (SCERT), the National Council of Educational Research and Training (NCERT), and the Indian Certificate of Secondary Education (ICSE) syllabi for classes IX or X. The study uses ten guidelines of Holocaust education devised by the United States Holocaust Memorial Museum (USHMM) for the textual analysis of the history chapters introducing the Holocaust in the primary texts. The study concludes that the NCERT textbook provides a more comprehensive understanding of the Holocaust compared to the Kerala SCERT or ICSE textbook
