A search for new physics in central exclusive production using the missing mass technique with the CMS detector and the CMS-TOTEM precision proton spectrometer

A generic search is presented for the associated production of a Z boson or a photon with an additional unspecified massive particle X, pp → pp + Z/γ + X, in proton-tagged events from proton–proton collisions at √s = 13 TeV, recorded in 2017 with the CMS detector and the CMS-TOTEM precision proton spectrometer. The missing mass spectrum is analysed in the 600–1600 GeV range and a fit is performed to search for possible deviations from the background expectation. No significant excess in data with respect to the background predictions has been observed. odelindependent upper limits on the visible production cross section of pp → pp + Z/γ + X are set

Not AvailableDairy Industry in India has been an important aspect in the development of the agricultural sector in the country. Information Technology coupled with communication technologies has emerged as frontier know-how for addressing complex problems related to any subject. Innovations made in the field of information technology have revolutionized the ways of collection, storage, retrieval, processing and communication of qualitative and value added information. The most important thing is that the technology needs to be an economical investment. It’s important to be careful not to invest in something just because it sounds like a good idea. It has to provide a return. The cost of manufacturing dairy products needs to be worked out off and on so as to fix the selling price of products which should, as far as possible, match with the prevailing market price. Software can be developed to find out these costs instantly by providing variable inputs costs, e.g., raw material and labour etc. and by using the pre-determined overhead costs in the process of manufacturing.Not Availabl

Not AvailableThis paper examines the employment generation potential of watershed development programmes and identifies the factors that contribute to the shift in labour absorption in farming activities over control situation. Analysis of secondary data collected from the watershed implementing agencies revealed that on an average watershed programmes helped to generate one time employment ranged between 26 and 76 mandays per hectare, for soil conservation, forestry and other works. Primary survey revealed that utilization percentage out of available labour at average households increased due to watershed development programmes. Employment elasticity with respect to various factors of production in crop cultivation worked out and showed negative price elasticity of demand for labour whereas, employment elasticity with respect to all other factors were found to be positive indicating their positive influence on labour demand. A decomposition analysis revealed that about 61% of the employment growth in watersheds over control situation was attributable to technology effect. Labour efficiency was much higher in the watershed than the control villages as evident from higher labour income. The study establishes that the watershed development programme had the potential of creating huge employment opportunities at the farm level in semi-arid tropical region of India.Not Availabl

Not AvailableOccurrence of frequent droughts of varying intensities is a critical constraint in improving agricultural productivity in the dry tropics. This paper quantifies meteorological drought from long-term annual rainfall data. Analysis of primary survey data from two watersheds indicated that moisture stress and fodder shortage were the major shocks experienced by farmers during drought, which caused low productivity of crops and animals. Farmers had their own strategies to cope with the drought like diversifying farming practices, borrowing, migration, sale of assets and livestock. The logit regression model indicated that coping strategies were influenced by number of earning family members, availability of irrigation facility, animal holding and income from non-farm sources. There is an urgent need to implement drought mitigation measures by central and state government institutions through both short and long term strategies covering technological and policy interventions like alternate cropping systems that augment soil moisture conservation, emphasis on water harvesting and ground water recharge, ensuring fodder and seed supplies, credit assistance, etc.Not Availabl

Not AvailableStudy was conducted in a semi-arid watershed with the objective to analyse the economic aspects of livestock enterprise. The study revealed that expenditure on feed and fodder and family labour formed the chunk among the different cost components. Average maintenance cost and returns from buffalo was highest compared to other type of animals. Labour use pattern reveals that the human labour input in livestock rearing was mostly family labour. The gross income per animal during a year was Rs. 4195.31 from cow and Rs. 6276.67 from buffalo inside watershed and the same was Rs. 4229.50 and Rs. 6412.00 outside the watershed. The results showed that there was little influence of watershed management programme over the yield and costing aspects of livestock enterprise.Not Availabl

Not AvailableThe study was conducted in semi arid region of southern part of India to examine the changes in productivity and returns due to implementation of watershed management projects. Data collected from 402 sampled beneficiaries and non-beneficiaries' (control) revealed significant difference in productivity of crops in watershed and control villages. Decomposition analysis of difference in returns from crop enterprises between watersheds and control villages indicated that the contribution of technological component was positive which signified that with the existing level of input use in the control farms, the returns from crops could have been increased significantly on implementation of watershed development programmes. This calls for a wider coverage of watershed development programmes in order to bring all the areas under land treatment activities for improving the productivity levels.Not Availabl
