Pasture Establishment and Sustainability in Arid Region of Rajasthan, India: Prospects and Constraints
Rajasthan is the largest state of India and covers nearly 10.4 per cent (342.65 lakh ha) of total geographical area of the country. About 65 per cent of its population is dependent on agriculture. According to livestock census-2007, Rajasthan ranks at the third place (56.663 million) in the country for total livestock population after Uttar Pradesh (60.272 million) and Andhra Pradesh (60.175 million). The large livestock population of the state shows importance of fodder in the state. Western part of Rajasthan state covers the area of the state towards western side of Aravali range of hills, which divides the state almost in two parts viz., eastern and western. The western part of the state is important for animal husbandry and forage management point of view. The reason is that this region is characterized as arid region and at many places in this region annual rainfall is below 250 mm. Many times droughts occur in this region and crop production for grain purpose does not become successful. So, farmers remain more dependent on animals than crops. Important animals in this region are cattle, buffaloes, sheep, goats and camels
Simplified micromechanics approach to analysis the performance of UD composites
A simplified micromechanical approach is used for the modelling and analysis of unidirectional (UD) compositeperformance. In this paper, the influence of volume fraction and constituent properties on the effective longitudinal,transverse, and shear properties of unidirectional composites are investigated. These effective properties are determinedusing the micromechanical approach, which is based on mathematical modelling using the rule of mixtures. Four differenttypes of unidirectional composites such as T300/BSL914C, IM7/8511-7, T300/PR319, and S2-Glass/epoxy were used foranalysis purposes. The method was validated with existing experimental results. The response is dependent on an array ofparameters, such as the orientation of fibers, the volume fractions of fibers, array of fibers and the material properties oftheir constituents. Further, this micromechanical method might be used with other reinforcing fibers for the prediction ofproperties of UD, hybrid and other composites architectures
