irrigation. The idea was to build 100 m of catchment area, and two concrete water storage tanks and irrigate one mu (1/15 hectare) of courtyard land devoted to cash crop production. In practice, the 1-2-1 program focused on building water tanks for household use, with roofs and courtyards serving as the principal catchment surfaces that channel water into the tank. County and township governmen...

energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...

Sustainability has strong implications on the practice of engineering. Life cycle assessment (LCA) is an appropriate methodology for assessing the sustainability of a wastewater treatment plant design. The present study used a LCA approach for comparing alternative wastewater treatment processes for small and decentralised rural communities. The assessment was focused on two energy-saving syste...

985 The Hanford Site in south-central Washington State produced plutonium for the USDOE weapons program from 1943 to 1989. Plutonium (Pu) production involved the fi ssion of uranium fuels using nine nuclear reactors along the Columbia River, followed by the extraction and concentration of trace product Pu through chemically intensive processing regimes performed in the central portion of the si...
