Abstract

The Indus River Basin (IRB), one of the major river basins in the Hindu Kush Himalaya, is primarily sustained by meltwater from the cryosphere. It caters to diverse sectors, including intense irrigation-supported agriculture, energy production, tourism and biodiversity. The cryosphere of the Upper Indus Basin (UIB) is mainly influenced by the western disturbances with subordinate contribution from the Indian Summer Monsoon. Increase in ambient temperature, shrinking cryospheric reserves, fluctuating surface run-off and enhanced frequency of extreme weather events are some of the noticeable indicators of climate change in the UIB. These changes will most likely adversely affect the water-dependent sectors in the upstream and downstream of IRB, posing serious threat to food security and livelihoods. Although the region has gained significant attention in recent years, there remains a noticeable knowledge gap pertaining to certain key issues with serious implications for the natural environment and the people. A national workshop was organized for stimulated deliberations to identify the major knowledge gaps and suggest a policy framework for climate change mitigation in the UIB. The workshop underscores the urgent need of multi-institutional, multidisciplinary, comprehensive, coordinated and time-bound collaboration to study the interplay of complex drivers on water resources of the UIB.

Keywords

Abstract

Free radicals are fairly unstable and highly reactive substances, causing oxidation and sometimes irreversible damage to cells. This has led to an increase in intake of antioxidants. Medicinal plants are being studied extensively for their antioxidant properties. The present study was aimed to study the in-vitro antioxidant activity of aqueous and methanolic extracts of Premna integrifolia Linn ischolar_mains (Verbenaceae). Both the extracts were subjected to various in-vitro antioxidant activity screening models such as DPPH, DMSO, ABTS, Nitric oxide and Iron chelation assay. Ascorbic acid was used as the standard. In all the models studied, the aqueous extract showed IC50 values of 111.009, 101.369, 99.976, 109.827, 105.239 μg/ml and the methanolic extract showed IC50 values of 98.252, 96.559, 88.163, 100.631, 95.005μg/ml for DPPH, DMSO, ABTS, Nitric oxide and Iron chelation assay, respectively.

Abstract

Decision making about resource allocation is a problem that we face every day, resource allocation is a multi-criteria decision making problem and goal programming is a common technique for solving resource allocation problems with multiple objectives. One of the most difficult decision in conducting examination is preparation of timetable and completing paper correction timely so that the results can be declared within the stipulated time. The determination of the optimum allocation of teachers becomes difficult, because of the multiplicity of factors, complex relationship among the factors like various programmes, course, availability of teachers, Availability of computers for online correction, Availability of answer sheets, Technical system and support etc. is often beyond the ability to identify the optimum allocation alternative. Thus it has become important to understand the capabilities and applications of the various quantitative or management science techniques so that one can thoroughly evaluate its alternative allocation opportunities. Preparing a good time schedule of Exam for a university is a most difficult task. The term “good time schedule” is questionable, because there is always someone, who is not satisfied with the given timetable. Nevertheless we can find out some objective criteria that indicate the “good time schedule”. The teacher simultaneously cannot assess different course at the same time. Numbers of students in different course are not equal .Same teacher teaching in different course. The aim of this study is to propose a goal programming model to solve the allocation of teachers satisfying all the constraint.

Keywords

Goal Programming, Time Table, Teachers Allocation for Paper Correction.

Abstract

Experimental investigations have been carried out to study the influence of various pulse parameters on TiG arc efficiency. L-shaped water cooled copper block as work piece and calorimetric set-up lor collecting the heat through the flowing water from the copper block were used, for determination of arc efficiency.

From the investigations it has been revealed that different parameters such as mean current, pulse current, background current, pulse frequency, arc gap, torch angle and gas flow rale influence arc efficiency. Except for gas flow rate, decreasing trends in arc efficiency have been generally observed with the increase of pulse / welding parameters.

Abstract

Murray Gell-Mann was among the very eminent and influential physicists of the second half of the 20th century. He was born in New York City on 15 September 1929. He graduated from Columbia Grammar School at the age of 14 and got his undergraduate degree from Yale at 18. Gell-Mann obtained his doctorate degree from MIT, under the supervision of Victor Weisskopf, in just two and a half years. He joined the Institute for Advanced Study, Princeton, in 1951 where he worked with Francis Low. During 1952–54, he was briefly on the faculty of the University of Chicago with Enrico Fermi and Marvin Goldberger. He joined Caltech in 1955 as an associate professor on the recommendation of Richard Feynman, where he continued until retirement in 1993 as Robert Andrews Millikan Professor of Theoretical Physics. 1993 onwards he remained the R. A. Millikan Professor Emeritus at Caltech and distinguished Fellow at the Santa Fe Institute. He was awarded the Nobel Prize in Physics in 1969 ‘for his contributions and discoveries concerning the classification of elementary particles and their interactions’. His students include Sydney Coleman, James Hartle, Kenneth G. Wilson, Christopher T. Hill and Barton Zweibach. He passed away in Santa Fe on 24 May 2019.

Abstract

There has been a growing awareness in recent years about the need for transforming engineering education in India that can enhance its effectiveness in serving the social and national goals. The efforts involved in these transformations pertain mainly to increasing the effectiveness of the processes of imparting knowledge, skills and wisdom by a teacher to a learner. However, most of these efforts are inspired by educational processes that are followed in the developed countries of the present. This paper is based on the contention that instead of following the developmental models of other countries if we seek motivations from our own past then we can surely approach our future as a developed nation faster. This is because history reveals that India before the British rule, i.e., Bharat excelled in all aspects of human development including science, engineering and education and enjoyed the status of a developed nation for a long unbroken period. In this paper we attempt a backward journey in time from India to Bharat to seek motivations from our inherent ischolar_main strengths. We then discuss how these motivations can illuminate our path towards achieving the desired transformations in the present engineering education in India, which can contribute to the resurgence of our glorious past, i.e., our re-emergence as a developed nation.
