Carbon black dispersions are superior to the best commercial silver and ceramic particle thermal pastes for providing high thermal contact conductance across mating surfaces that are smooth (0.05 lm). For mating surfaces that are rough (15 lm), the combined use of carbon black and silver is more effective than carbon, silver or ceramic pastes. The use of a silver paste to even out the rough sur...
Recent discovery of low concentrations of bromacil in drinking water prompted the State of Hawaii to examine the leaching behavior of bromacil in pineapple fields. This study is a follow up to earlier work on bromacil concentrations in soil profiles in a pineapple field in central Oahu, Hawaii. Soil samples were collected for bromacil analysis at different times prior to and after application f...
Rainfall harvesting and storage in soil depth through micro catchment contribute to curtail water deficiency of plants. The objective of this research that was conducted in Kaboodeh-Olya village in Kermanshah province, Iran, was to compare the effects of three different micro catchment systems on soil moisture storage including flat, crescent and rhombus shaped. The experimental research was pe...
Introduction: Wind erosion and thunderstorms bring about significant adverse consequences, including air pollution, reduced visibility, wear and tear of industrial machinery, soil structure destruction, and adverse effects on soil fertility. In recent years, the aerosol pollution caused by sand storms has turned into a serious health threat for Iranian people. In addition to being detrimental t...
Most crops are affected by various factors, plastic mulch emerges as an alternative, causing a positive impact on the temperature in root zone, microbial life and physical properties of soil associated with improvement crop yield. The objective research was to evaluate yield soybean (Glycine max L.) under conditions. Geotemperature parameters, net heat flow from morphological variables were ana...
