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 physical and radiation shielding parameters of erbium doped zinc boro-tellurite glasses

    In this work, physical and radiation shielding parameters of Erbium doped Zinc Boro-tellurite (EZBT) glasses were studied. The glasses of composition 20ZnO- 25B2O3- (55-x) TeO2-xEr2O3 with x= 0, 0.5, 1.0, 1.5 and 2.0 in mol % were synthesized using melt-quenching method. These samples were characterized by different techniques i.e. Standard displacement technique, X-ray diffraction and FTIR to examine various properties. The values of density and oxygen packing density (OPD) were increased with increasing concentration of erbium while the molar volume was found to be decreasing with increasing concentration of erbium oxide. The amorphous nature of these glasses was confirmed by XRD technique. The mass attenuation coefficient ( ) of the samples was obtained using WinXCom software and other relevant relations were used to calculate the Half-value layer (HVL), Mean free path (MFP), effective atomic number ( ) and effective electron density ( ) in the energy 0.01 MeV− 10 MeV. Results showed that the shielding properties improve with the increasing amount of erbium oxide and the maximum values of and were found for 2.0EZBT glass sample. Also, that particular sample has shown the lower value of HVL and MFP, which results in more attenuation and thus better shielding features. The parameters at diagnostic energies (20 keV, 30 keV, 40 keV and 60 keV) were compared with lead glass and ordinary concrete. The outcome shows that all the glass samples are capable of replacing ordinary concrete and lead glass at 40 keV and 60 keV. Moreover, 2.0EZBT showed the best shielding performance among the selected glasses at medical diagnostic energies. Hence, the results of this current investigation are useful in designing the lead-free radiation shielding material in diagnostic radiology.
