The IAAF’s hyperandrogenism regulations suspended
No full textOn 27 July, the Court of Arbitration for Sport (‘CAS’) delivered a landmark ruling on the regulation of gender in sport. The decision explores how the categorisation of sport on the basis of sex can be best reconciled with the “biological reality” that human sex cannot necessarily be divided so clearly. Dr. Seema Patel, Senior Lecturer at Nottingham Trent University, Deputy Director of the Centre for Sports Law and author of ‘Inclusion and Exclusion in Competitive Sport: Socio-Legal and Regulatory Perspectives,’ reviews the case and suggests that sport regulation must be cautious of traditional criteria to determine eligibility in sports
Jun N-terminal kinase 1 (JNK1) as a molecular target to limit cellular mortality under hypoxia
No full textMany pathological conditions and environmental impacts lead to a decrease in tissue oxygen supply and severe cellular hypoxia. This secondary hypoxia can disturb cellular homeostasis, limiting the efficacy of the prescribed treatment for the primary disease, eventually leading to cellular and organismal death. Jun N-terminal kinase 1 (JNK1) plays a central role in the development of cellular damage under hypoxia, hypoxia/reoxygenation and ischemia/reperfusion conditions. Therefore, we selected JNK1 protein as a molecular target to limit cellular damage and death during hypoxia. The primary objective of this research was to study the influence of the suppression of JNK1 on the development of cellular hypoxic damage. It was hypothesized that suppression of JNK1 will decrease cellular mortality under hypoxia and may increase the efficacy of traditional treatment of many pathological conditions. The hypothesis was verified under both in vitro and in vivo conditions. Another objective was to develop a non-viral system for intracellular delivery of antisense oligonucleotides (ASO) and small interfering RNA (siRNA). ASO and siRNA targeted to JNK1 mRNA delivered by neutral and cationic liposomes, respectively, showed high efficiency in suppressing JNK1 protein. Such suppression limited the caspase dependent apoptosis signaling pathway and decreased cellular mortality induced by severe hypoxia. The results suggest that JNK1 protein might be an attractive target for antihypoxic therapy to increase resistance to many pathological conditions and diseases accompanied by cellular hypoxia.Ph.D.Includes bibliographical references (p. 138-153)by Seema S.

The Post Office Horizon system and Seema Misra
No full textThe author highlights the significance of the Seema Misra case in raising questions about the reliablity of the Post Office Horizon system and more widely suggesting that all digital systems have the possibility of latent defects, and these can never be discounted. He argues that when the efficacy of digital systems is called into question in legal proceedings, the onus of proof must be placed on the supplier of these systems and not the accuser.Index words: Post Office; Horizon; prosecutions; software errors; disclosure Full transcript of the trial Regina v Seema Misra, T2009007 (England & Wales; theft; electronic evidence; Post Office Horizon System; ‘reliability’ of computers) with case commentary and index to original papers held in the Documents Supplement of Volume 12: 2015
Development of novel zein-cellulose nanocomposite films
No full textZein is a hydrophobic biopolymer, which naturally forms biodegradable films. These films are rigid, brittle, and lack good mechanical and barrier properties for packaging applications. This study aims at improving the mechanical and barrier properties of zein films by the development of zein-cellulose nanocomposites. A ‘nanocomposite’ is a mixture of polymer matrix, which forms the continuous phase and the filler (having at least one dimension less than 100nm), which forms the dispersed phase. Zein-cellulose nanocomposites have zein as the matrix and cellulose as the filler. Nano-sized cellulose was prepared using wet-media milling machine and mass ratios of 1%, 3%, 5% and 10% of both, naked (not stabilized) nano-cellulose and GA - stabilized nano-cellulose were used in the film formulation. Tributyl citrate (TBC) was used as the plasticizer. The films were prepared using solvent-cast technique and characterized to test their mechanical and barrier properties. The controls were pure zein films and films with only plasticizer. Texture Analysis showed that filler loading of 5% was most effective in increasing the elongation-at-break to about 16 to 20 times of the controls. However, the tensile strength did not change. Water vapor permeability of the nanocomposites was minimum at 1% by wt. of naked cellulose (~4 times less than control) or at 5% by wt. of stabilized cellulose (~6 times less than control). Water absorption results showed that the rate of water uptake decreased as the filler loading increased. DSC and FTIR suggested that there is no interaction between the zein and the nano-cellulose in the films. The AFM results showed that the films’ surface is flat, but the thickness of the films increased with filler loading. Therefore, incorporation of nano-cellulose improved the flexibility and water barrier properties of the films. Gum Arabic, which was used as a stabilizer for nano-cellulose, seemed to have aided the even distribution of cellulose in the zein matrix. Thus, these films can be a good starting point to further study the arrangement of cellulose within the zein matrix and test its potential applications on food systems and as edible films.M.S.Includes bibliographical referencesby Seema Lakshmana Ra

ABSTRACT
The degree of roughness characterizes the uncertainty contained in a rough set. The rough entropy was
defined to measure the roughness of a rough set. Though, it was effective and useful, but not accurate
enough. Some authors use information measure in place of entropy for better understanding which
measures the amount of uncertainty contained in fuzzy rough set .In this paper three new fuzzy rough
information measures are proposed and their validity is verified. The application of these proposed
information measures in decision making problems is studied and also compared with other existing
information measures.

Assessment of Landslide Susceptibility in the Himalayan Region: A Case Study of Rishikesh-Yamunotri Corridor
No full textThe findings of the statistical models based on geographic information systems (GIS) for creating landslip susceptibility maps utilising remote sensing data and geographic information systems for the Rishikesh to Yamunotri corridor of Uttarakhand are presented in this study. Cartosat, Landsat, IMD, and India water resources data were used to extract ten factors: slope, aspect, soil, lithology, NDVI, LULC, distance to stream, precipitation, distance to road, and elevation. Using GIS-based statistical models, such as the analytical hierarchy process (AHP), which assigns ranks and weights to various factors to determine which factors are more responsible for landslides, the relationships between the detected landslide locations and these ten related factors were identified. The three landslide zone categories, high, medium, and low, on the landslip inventory map were developed using various things like field surveys and digital aerial photos. Regional planning and hazard mitigation would benefit from these landslip susceptibility maps

No full textResearch Reimagined: The Dissertation-to-Book Journey and Building a Scholar-to-Author Presence
No full textThis capstone project, completed for a second master\u27s degree after a Ph.D., discusses aspects of transforming the doctoral dissertation on digital versus manual mediums in fashion design into a research monograph book proposal for academic publication. It reflects on a publisher\u27s requirements and the process, including de-thesizing the dissertation, planning the book\u27s structure, rewriting sample chapters to improve flow and readability, and creating a table of contents that demonstrates the work\u27s development into a publishable book rather than a dissertation. Another part of the project includes developing an author platform through blog posts and platforms such as Substack, preparing the groundwork for connections between the research and broader audiences. Due to the unpublished and proposed nature of the work, some details are not included in this document
