Performance measurement with undesirable outputs is an important subject in production processes. There are papers in which works can be divided into two groups. First group develops production models which undesirable outputs are considered as inputs and in second one undesirable outputs are modeled as outputs. We provide a comparison between these two groups and we axiomatically show that pro...
krytyn triplet alkyl esters ayzvsyanydha reactions and lead to the production of acetylene is stable.
Research on the labor market impact of immigration typically relies on a single-good model of production with separable capital. This article discusses theory and evidence that suggest that this standard model is too simple to capture the labor market impact of immigration. A reasonable level of capital-skill complementarity, for which there is considerable support outside research on immigrati...
Detasseling is used in hybrid corn (Zea mays L.) seed production to ensure harvested seeds have the desired genetic complement. Both mechanical and hand detasseling result in loss of some leaf tissue and plant N. The objective of this study was to determine if seed yield and quality and N content of grain and stover were affected by leaf removal during detasseling. The treatments evaluated were...
Thin film photocathodes have been developed both for gas and vacuum based photodetectors. Over the last years we have gained experience in fabricating large area reflective CsI and semi-transparent monoand bialkali-cathodes, i.e. Rb2Te and K2CsSb: Today we are producing stable cathodes with excellent quantum efficiency for large MWPC based pad detectors and Hybrid Photodiodes on a routine basis...
Abstract Hybrid technology, harnessing the advantage of heterosis between two diverse genotypes to achieve maximum hybrid vigour, is widely recognized and commercially used for crop variety improvement both in field vegetable crops. Hybrids can be developed using appropriate irrespective mating pollination system plant species. Production seed depends on plant, pollinator environmental factors,...
Introduction The increasing population growth and the need for more agricultural products on the one hand, and on the other hand, the limitations of agricultural development are problems that human beings have always tried to solve. Due to the limited resources and inputs of production, it seems that further production growth is possible through advanced technologies. In fact, technology is so...
Zero-energy city, sustainable City and zero-carbon city are new terms in cities’ energy management. In this study, a framework of designing a Low-Carbon Eco-City (LCEC) in urban sector of Mashhad with focus on sustainable supply of electrical energy has been simulated. For this purpose, the maximum potential of biomass renewable electricity and expansion of photovoltaic capacity- required to co...
