Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Study of electrical and magnetic properties of cobalt based metallic glasses and composite material
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-07) Agrawal, Rati; Kushwaha, R.P.S.
    There are many materials of commercial importance; composite materials and metallic glasses are two such important materials among them. Wide variety of technological and industrial applications of these materials motivates the present work. Cobalt based metallic glass of nominal composition Co60B12Si12Fe4Mo2Ni1 and cobalt based composite material prepared by varying concentration of cobalt metal powder in plaster of paris was used for investigating their electrical and magnetic properties. For cobalt based composite material change in A.C. magnetic susceptibility with both frequency and concentration have been taken into account. Similarly temperature and concentration dependence of electrical resistivity of composite material was investigated. From experimental results obtained, A.C. magnetic susceptibility was found to decrease with frequency for all concentrations and increase in susceptibility was observed when plotted with concentration. when electrical resistivity of cobalt based composite material was investigate for its temperature dependence, slight decrease in resistivity or a dip was observed for all the concentrations i.e. for all the samples with different concentrations of cobalt metal powder in plaster of paris. Energy losses in the samples were also measured by studying their hysteresis loops for two different frequencies.

    Study of the role of pair transfer processes on isotope effect in superconducting TTF[Ni(dmit)2]2 systems
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-06) Pant, Manju; Ajay
    In the present investigation, we have studied the role of interband pair transfer processes on isotope effect in layered TTF[Ni(dmit)2]2 systems. For this purpose we have considered two chain Hubbard model that includes the intra and intermolecular vibrations in the presence of electron Coulomb energy and the electron transfer energy between the chains. Such a model calculations will be applicable for the organic superconductors where molecular layered structures are available. We obtained the expressions for the superconducting order parameter, transition temperature and finally the isotope effect coefficient ( ) using double time Greens’s function equations of motion technique within BCS mean field approximation. Finally the numerical analysis show that isotope effect coefficient ( ) depends on the intra and interlayer molecular vibrations, the pair transfer processes and also on the superconducting transition temperature (Tc) in layered organic superconductors like TTF[Ni(dmit)2]2 . On the basis of our model calculations we have predicted the effects of the pair transfer processes, the density of states at Fermi level and the chemical pressure on the isotope effect coefficient which need to be tested through rigorous experimental investigations on these systems.

    Determination of leaf water parameters of sarpgandha (Rauwolfia serpentina L.) plant using beta gauging technique
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-07) Tiwari, Bhoopendra Chandra; Joshi, G.C.
    The present study is concerned with the determination of the physiological parameters such as fresh leaf thickness and water content (actual and relative) of a medicinal herb Sarpgandha (Rauwolfia serpentina L.) leaves. We have measured the changes in these physiological parameters as a function of height of leaves from ground level. These parameters were calculated by beta gauging method by using 204Tl and 90Sr- 90Y beta sources of energy 0.77 MeV and 2.28 MeV respectively. The results were also compared with weighing method. The observations showed that the fresh leaf thickness decreased exponentially with the height of plant leaves from ground level. However, the actual water content and relative water content increased exponentially with the distance of leaves from ground level. The actual water content and the relative water content showed the linear relationship. The mass absorption coefficient ( ) was also determined by the beta gauging method and compared with the empirical relation. The observations showed that the mass absorption coefficient depend only on the end point energy of beta particle. The study further suggests that the beta gauging method is a rapid, effective, non-destructive and powerful tool to follow the changes in physiological parameters of plant leaves.
