(Major Research Project, 2018-07-30) Krishna, Amitabh
Oxytocin (OT) is normally a neurohormone stored and secreted from posterior pituitary. It has been postulated to facilitate reproduction at several levels and is traditionally considered as a female hormone. Within male reproductive tract, the presence of OT was demonstrated in the testes, epididymis and prostrate. Thus the aim of this study was to elucidate the role of OT in spermatogenic and steroidogenic activities in the testes of mice.
Genetic diversity and phylogenetic analyses of cyanobacteria based on nif K, psb A and ntcA conserved sequences
(Department of Botany, 2015-08-31) Mishra, A.K
Cyanobacteria are photosynthetic prokaryotes, which possess mainly chlorophyll-a. Cyanobacteria are approximated to have occurred as a long ago as 2,600 to 3,500 millions years based on fossil records, organic biomarkers and genomic sequence analysis. They are known to inhabit a range of habitats, including plant surfaces but this has not been adequately explored for improving their biofertilizing potenctial in agriculture and the rhizosphere is a relatively unexplored frontier.
Genetic improvement of tomato for high temperature stress
(Department of Genetics and Plant Breeding, 2013) Srivastava, Kartikeya
Tomato is one of the most popular and widely grown vegetables throughout the world either in outdoors or indoors because of its wider adaptability and versatility. Tomato is usually produced during the winter season in India and fruit production is gradually dropped as the temperature increases by the end of the winter season. In summer due to high temperatures, tomato production almost ceases and shortage of tomatoes is common.

Identification of co-scholastic assessment practice and suggestions for their uniformity in CBSE schools of Varanasi
(Faculty of Education, 2018-07-30) Bajpai, Anjali
In order to have Continuous and Comprehensive Evaluation, both Scholastic and Co-Scholastic aspects need to be given due recognition. Such a holistic assessment requires maintaining an ongoing and comprehensive profile for each learner that is honest, encouraging and discreet. While teachers frequently reflect, plan and implement remedial strategies, the child’s ability to retain and articulate what has been learned over a period of time also requires periodic assessment.
Impact of financial literacy and financial stress on well being: a case study of handicraft workers of Varanasi region
(Institute of Management Studies, 2018-07) Chakraborty, Anindita
The field of personal finance is better reflected in recent years in specialised research, i.e. financial education. The principle idea is that without passable knowledge and skills one cannot effectively manage his or her finances, particularly in this dynamic and complex economic environment. However, besides education, there are other aspects that came out from the literature, which appears to have particular importance in the process of individual financial decision. Therefore, personal finance and financial education plays a vital role in an individual’s life and thus are essential topics. The financial education movement proliferated in the mid- to late-1990s in response to financial sector reforms in many countries, and thus attention needs to be placed in the context of the state-of-the-art research, from which future research can come into sight. The financial decision-making process is complicated in the case of individuals and households and may get influenced by various factors. With financial products becoming more and more complex; growing role of technology in the financial sector; shifting of employers attention from traditional pension plans to market linked plans have created apprehension in the mind of policymakers regarding the precautionary measures taken by the financial institutions and lack of financially educated people. Thus the need for improved education in the field of personal finance is felt and large number of nationally representative organisations in India and worldwide to promote financial education were established to promote financial education. Financial decisions are a part of everyday life – whether looking for ways to save, deciding which credit card represents the best value, choosing a home loan, comparing insurance policies or planning for retirement. Whatever the decision, being confident and informed can make a difference to the financial wellbeing and peace of mind of an individual and a household. For taking better financial decisions, one needs to have some financial knowledge, or he/she should be financially literate. Therefore, financial literacy is the capability to of an individual to understand how to use money in the real world. It deals with how people manage to earn or make it, how they manage it, how they invest it and how they help others by donating it. In absence of financial literacy one can end-up by making poor financial decisions, and that can affect their financial wellbeing. Therefore, with raising interest in personal finance in countries like Australia, Japan, the United States, UK and India it is now necessary to focus on state-run programs to protect the people from any type of financial mis happenings and this can only be done by properly educating them.
Ion exchange voltammetry as a versatile technique for selective determination of target analytes using novel organicploymers and functionalized clay materials
(Department of Chemistry, 2018) Ganesan, V
A voltammetric sensor for both the individual and the simultaneous determination of ascorbic acid (AA), uric acid (UA) and folic acid (FA) is described. It is based on a glassy carbon electrode (GC) that was modified with bentonite (Bt) that was first functionalized with cysteine (Cys) to which gold nanoparticles were linked. The resulting material (referred to as Au-Cys-Bt) and the other materials were characterized by UV-vis spectroscopy, powder X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray analysis and electrochemical methods. The XRD peak positions of bentonite and Cys-functionalized bentonite prove the incorporation of Cys into bentonite. The XPS spectrum of Au-Cys-Bt confirms the interaction of gold nanoparticles with the thiol group of Cys. The modified GC displays high electrocatalytic activity for the oxidation of AA, UA and FA, typically at 0.19, 0.41, and 0.73 V (vs. SCE), respectively. Differential pulse voltammetric data show a linear response that covers the 1 μM to 25 mM concentration range for AA, the 1 to 200 μM concentration range for UA, and two linear ranges for FA, one from 5 to 100 μM and one from 100 μM to 1.5 mM. The sensor was applied to the determination of AA, UA and FA in (spiked) multi-vitamin syrup, bird serum and milk samples.
A low cost approach to remediation of Cadmium contaminated soils using organic and inorganic amendments
(Department of Soil Science and Agriculture Chemistry, 2015-06-30) Ghosh, Amlan Kumar
Over the past few decades, the term heavy metals (such as lead, mercury, and cadmium) have been associated with contamination and potential toxicity or eco-toxicity, even at low concentration tend to bio-accumulate and cannot be processed by living organisms (Rand et al., 1995). Often as pollutants, which poses severe threats to environment and their occurrence in soils indicates the presence of natural or anthropogenic sources (Yoon et al., 2007).
Mathematical modeling of emission and control of greenhouse gases
(Department of Mathematics, 2018-06-30) Mishra, A.K.
The enhanced concentration of carbon dioxide (CO2) in the Earth’s atmosphere is significantly responsible for the menace of global warming and the associated climate changes [29]. The increment in the concentration of atmospheric CO2 is attributed to human activities such as fossil fuel burning and land use changes [29]. Deforestation accounts for nearly 90% of CO2 emissions from land use changes [28]. Forests are one of the major sinks of CO2 on the Earth. Trees during the photosynthesis process absorb CO2 from the atmosphere and stock it in the form of biomass. Every year forests absorb gigatons of carbon in this process. Clearing of forests causes increase in concentration of CO2 in two ways; firstly, it reduces the global uptake of CO2 through photosynthesis process and secondly, the carbon stored in the trees is released back to the atmosphere in the form of CO2 when the wood is burned or left to decompose after deforestation. In the last few decades, global forest biomass has declined at an alarming rate. Between 1990 to 2005, the total forest area has declined at annual rate of 0.21% and the carbon stock per hectare in forest biomass has declined at the rate 0.02% [15]. This severe destruction of forest has contributed significantly to the inexorable rise of atmospheric concentration of CO2.
Modulation of Nitric Oxide synthases and induction of apoptosis in hepatocellular carcinoma by fiestin
(Department of Zoology, 2015-06-30) Trigun, S.K
Fiestin, a natural flavanol, found in many common fruits and vegetables, was evident to modulate tumor growth associated signaling cascade in HCC cells in vivo and thus provided a cellular and molecular basis of anti cancer activity of this compound. Thus, this outcome provides a base line data to (a) evaluate translational feasibility of fisetin as an effective anti-HCC therapy and (b) advocates fruits and vegetable rich diet to prevent development of HCC and other tumor growth in human subjects.
A novel study of nanolayered tunable optical filter based on photonic band gap materials with various applications
(Department of Physics, 2015-12-31) Srivastava, Sanjay Kumar
In this work, a highly sensitive surface plasmon resonance (SPR) biosensor with Kretschmann confguration having alternate layers, prism/zinc oxide/silver/gold/graphene/biomolecules (ss-DNA) has been presented. The eﬀect of zinc oxide layer thickness on the sensitivity of SPR biosensor has also been analyzed. From the analysis, it is found that the sensitivity increases significantly by increasing the thickness of zinc oxide layer. The sensitivity of the proposed SPR biosensor has been demonstrated for a number of design parameters such as gold layer thickness, number of graphene layer, refractive index of biomolecules and the thickness of biomolecules layer. SPR biosensor with optimized geometry has greater sensitivity (66 deg/RIU) than the conventional (52 deg/RIU) as well as other graphene based (53.2 deg/RIU) SPR biosensor.
