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.

    Optimization of resistance spot welding process parameters for cold rolled mild steel lap joint based on tensile shear strength
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-10) Pankaj Kumar; Bisht, Neeraj
    Owing to its numerous applications weld characteristics of cold rolled mild steel grade IS 513 CR 1 was investigated. Resistance spot welding, one of the most versatile welding technology was used for the purpose. The three most important parameters of the RSW namely welding current, welding time and electrode pressure were varied and the influence on the Tensile Shear Strength (TSS) was evaluated. The experiments were carried out according to Taguchi's L9 orthogonal array and Taguchi analysis was used in optimization. A lap joint of dimensions 120mm x 30 mm x 1.5mm was welded using a 100 kVA timer, current-controlled CSP-100PR Spot Welder, to create an overlap of 3 mm thickness. According to Taguchi’s L9 OA welding current cycles of 5, 10 and 15 were selected. During the welding process, the welding current was changed by adding 2 kA from 10 to 14 kA and the electrode pressure were taken to be 4, 5 and 6 bar. The Main effects plots revealed the optimal setting for the process parameters as welding current of 14 kA (Level 3), welding time of 15 cycles (Level 3), and electrode pressure of 4 bar (Level 1). The optimized process parameters showed the maximum TSS of the spot weld joint. ANOVA was carried out to identify the significant process parameters affecting the weld strength. Furthermore, the contribution of welding current was found to be 67.38% which had the maximum influence on the TSS of the welded joint. The contour plots showed that on increasing welding current and welding time with decreasing electrode pressure the Tensile Shear Strength of lap joint was increased by 55.78%, 26.27% and 33.65% respectively

    Performance and emission characteristics of diesel engine fuelled with wintergreen biofuel and diesel with diethyl ether as an additive
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Pankaj Kumar; Tewari, P.C.
    Energy is a fundamental component of social and economic development. A nation's energy strategy aims for productivity and security, as well as providing environmentally friendly access and achievement of primary resources for energy generation. Petroleum fuels will continue to play a dominant role in our country's energy sector in the coming decades. However, conventional fuel resources are limited, non-renewable, and polluting, and should thus be used with caution, whereas renewable energy sources are indigenous, non-polluting, and abundant. As a result, their use should be encouraged in any way possible. The aim of this present work is to blend wintergreen biofuel with diesel and diethyl ether in the proposed percentage and to test performance parameters such as brake power, fuel consumption, brake specific fuel consumption, brake thermal efficiency, and emission characteristics (exhaust temperature, smoke density, exhaust gas emissions) experimentally on 3.7 kW rated power, single cylinder four stroke compressed ignition engine. The current study led to the conclusion that wintergreen oil blending in diesel is restricted to 30% for comparable performance and emission characteristics with diesel fuel. Increasing wintergreen biofuel proportion led to increased performance characteristics such as BTE, BSFC and reduced CO emissions and decreased smoke density. It is concluded that wintergreen oil blended 20% in diesel gives best performance and emission characteristics at all loads.
