Solar thermal electricity technologies are attractive alternatives to produce electricity by means of a renewable source. One of these technologies is parabolic trough collectors. In Spain, the sale of solar electricity to the national grid is primed. There are three main parameters that affect...

The amount of water used by any crop largely depends on the extent to which the soil water depletion from the root zone is being recharged by appropriate depth of irrigation. To test this hypothesis a field study was carried out in November-March of 2002-2003 and 2003-2004 on a sandy loam (Aeric...

The effective utilization of resources in seeking to reduce accidents in mines requires that the accident experiences of different mines should first be placed on a comparative footing. There could be many characteristics of belowground mines which influence the occurrence of accidents....

Water-harvesting structures have the potential to increase the productivity of arable lands by enhancing crop yields and by reducingthe risk of crop failure in arid and semi-arid regions, where water shortages are common because of scanty rainfall and its uneven distribution. In semi-arid...

Domestic water use/demand is a complex function of socio-economic characteristics, climatic factors and public water policies and strategies. This study therefore develops a model based on the multivariate econometric approach which considers these parameters to forecast and manage the domestic...

The paper explores whether one of the largest programs in the world for women's empowerment and rural livelihoods, the Indira Kranti Patham in Andhra Pradesh, India, has had an impact on the economic and social wellbeing of households that participate in the program. The analysis usespanel data...

Optimization of thermal systems is generally based on thermodynamic analysis. However, the systems so optimized often are not viable due to economic constraints. The Theory of Exergetic Cost, a thermoeconomic optimization technique, combines the thermodynamic analysis with that of economic...
