The main obstacle for the further development and commercialization of solid-state DC circuit breakers is the high ON-state power losses caused by the active power semiconductor devices.This paper presents an experimental evaluation of the electrical ON-state performance among several commercial high-power semiconductor device technologies rated at
The National Atmospheric Deposition Program (NADP) developed and operates a collaborative network of atmospheric-mercury-monitoring sites based Plates in North America – the Atmospheric Mercury Network (AMNet).The justification for the network was growing interest and demand from many scientists and policy makers for a robust database of meas
Thorough studies of previous analytical stress data of tetrabenazine, a dopamine depleting agent, showed a potential susceptibility to acidic conditions.Hence, the behavior of tetrabenazine acidic solutions was studied by LC-MS and NMR spectroscopy.Reverse-phase LC-MS analysis of tetrabenazine acidic aqueous solutions consistently showed a main lip
"nBackground: Sunlight exposure is one of the ways for vitamin D synthesis.However, its effect on vitamin D status via experimental studies is poorly understood.This study was undertaken to address the possibility that sunlight exposure may increase the levels of serum vitamin D, and alter bone turnover in healthy young girls."nMethods: I
