Power electronics play an important role in electricity utilization from generation to end customers. Thus, highefficiency power electronics help to save energy and conserve energy resources. Research on silicon carbide (SiC) power electronics has shown their better efficiency compared to Si power electronics due to the significant reduction in both(More)
The authors have evaluated a number of organophosphorus compounds for residual contact toxicity to adult Anopheles stephensi. Fenthion and malathion were the most promising of the compounds, and wettable powder deposits at a dosage of 1 g/m(2) on plywood remained effective for five months. There was, however, a rapid loss of effectiveness on dried mud(More)
Laboratory experiments have shown that the sorption of two organophosphorus compounds, malathion and fenthion, and a carbamate, UC 10854, on dried muds is influenced by atmospheric humidity and that the biological activity of a given concentration of sorbed insecticide increases with increasing humidity. The residual action of these insecticides on dried(More)
Responses shown by female mosquitos to topical applications of solutions, to deposits from water-dispersible-powder formulations, or to exposure to the vapour from such deposits, are described for a number of compounds that have shown promise as residual contact insecticides.The behaviour of Anopheles stephensi females in laboratory tests indicates that(More)
A key issue with Hybrid Electric (HEV) and Plug-in Hybrid Electric Vehicles (PHEV) is the cost of these products relative to traditional vehicles. Currently in most cases, the fuel savings do not offset the initial capital expenditure associated with a hybrid. Therefore, an important goal is the cost reduction of these products in order to allow consumers(More)
