Struggle For Substantive Justice And Community Development: Transgender Subjects In Contemporary India, Pushpesh Kumar Dec 2021

Struggle For Substantive Justice And Community Development: Transgender Subjects In Contemporary India, Pushpesh Kumar

ASEAN Journal of Community Engagement

This paper discusses the transgender community's fight for justice and developmental rights since 2014 and the response of the Indian Government toward this assertion. The point of choosing 2014 as the starting point is not because the fight for their justice actually begins in this year but because India witnessed an intensification and an increase in public visibility of transgenders’ mobilization following the recognition of members of transgender communities as legal citizens through the landmark Indian Supreme Court (Court) verdict called the National Legal Services Authority Union of India (NALSA). In documenting transgenders’ mobilization and the state's response, the author …

Mitigating The Spread Of Measles Under Constrained Health Care Resources In Tanzania Using Social Contact Network Models, Herieth Rwezaura, Seán Mcgarraghy Dec 2021

Mitigating The Spread Of Measles Under Constrained Health Care Resources In Tanzania Using Social Contact Network Models, Herieth Rwezaura, Seán Mcgarraghy

Tanzania Journal of Science

Tanzania revaccinates individuals during measles outbreaks, despite having scant healthcare resources. We construct epidemiological models of measles spread by employing a hybrid of existing social contact networks models to develop SEIR simulation model. Using demographic and measles surveillance data from three rural villages in Tanzania, we simulate the spread of measles and examine which vaccination strategies can effectively control outbreaks. Results strongly indicate the spread of measles largely depends on contact rates among infected individuals within a population. Findings indicate a need for targeted vaccination for children of 6 months to 15 years of age, but equally for unvaccinated older …

Adaptive Sliding Mode Contouring Control Design Based On Reference Adjustment And Uncertainty Compensation For Feed Drive Systems, Mathew Renny Msukwa, Santos Kihwele Dec 2021

Adaptive Sliding Mode Contouring Control Design Based On Reference Adjustment And Uncertainty Compensation For Feed Drive Systems, Mathew Renny Msukwa, Santos Kihwele

Tanzania Journal of Science

Industrial feed drive systems, particularly, ball-screw and lead-screw feed drives are among the dominating motion components in production and manufacturing industries. They operate around the clock at high speeds for coping with the rising production demands. Adversely, high-speed motions cause mechanical vibrations, high-energy consumption, and insufficient accuracy. Although there are many control strategies in the literature, such as sliding mode and model predictive controls, further research is necessary for precision enhancement and energy saving. This study focused on design of an adaptive sliding mode contouring control based on reference adjustment and uncertainty compensation for feed drive systems. A combined reference …

Assessment Of Seasonal Variations In Forage Quality In Saanane Island National Park, Mwanza, Tanzania, George M. Sangu, Cuthbert L. Nahonyo

Tanzania Journal of Science

Seasonal variations in proteins, vitamin A, vitamin C, carbohydrates and minerals (Ca, Fe, Na, K and P) for seven most grazed and four most browsed plant species were assessed using laboratory analysis to determine what nutrient resources were available to grazers and browsers inhabiting the Saanane Island. The results indicated great seasonal variations in proteins, vitamin A, vitamin C and carbohydrates which were statistically significant with P < 0.01, F 3.444 at DF 5. Similarly, the minerals (Ca, Fe, Na, K and P) showed greater seasonal variations with K and P being higher during wet season, while Na and Fe were higher in dry season. The levels of proteins, vitamins, fibres and minerals were well above daily dietary requirements for grazers and browsers. These results suggested that both grazers and browsers were benefiting from seasonal differences in terms of available resources at disposal as animal health is regulated by levels of proteins and vitamins available in grazing and browsing materials.  Keywords: Forage Quality, Minerals, Protein Saanane, Seasonality, Vitamin

Application Of Faulkenberry (2018) Bayes Factor To A Balanced Two Way Analysis Of Variance With Random Effects, Onyeike D. Egburonu, Omotayo A. Abidoye

Tanzania Journal of Science

The Analysis of Variance technique estimates variance components by comparing their mean squares to their expected values. Nevertheless, this method could give variance component estimates that are found outside the parameter space, i.e. negative estimates. In a bid to overcome this deficiency, alternate approaches are essential, and likelihood-based approaches have become common over time. Bayesian techniques have also been proposed and Bayes factors developed for examining various models. We applied the Bayes factor proposed by Faulkenberry (2018) to a Balanced Two Way ANOVA under three (3) cases, namely Case 1: the levels of the two factors are fixed; Case 2: …

Journal of Bioresource Management

Lithium is a relevant mood-stabilizing agent that is used in the management of depressive and manic episodes in bipolar, disorder; however, its application may cause diverse side effects including oxidative stress. This work investigated the neuroprotective and anti-stress activity of Ulva lactuca extract (MEUL) against lithium induced neuronal toxicity in rats. Lithium (2 g/kg) was administered in diets with or without MEUL (250 mg/kg BW by gavage) for 90 days. Lithium induced oxidative stress lead to an elevation in lipid peroxidation and oxidation protein product levels, a reduced superoxide dismutase, glutathione peroxidase activities, glutathione, and ascorbic acid concentrations in brain. …
