Metabolic profiles of carbaryl in human postembryonic fetal autopsy tissue were determined using an in vitro tissue-maintenance technique. 1-Naphthyl-14C or N-methyl-14C-carbaryl was applied to growth medium containing explants of the tissue. Each mixture was incubated for 18 hr and the medium analyzed by DEAE-cellulose column chromatography. Fetal liver(More)
A half-bridge inverter circuit capable of providing a wide range of ac output voltages and frequencies is presented. The inverter uses asymmetrical thyristors (ASCR's), which have the advantages of high-power handling capability, small turn-on and turn-off times, and exhibit the same ruggedness associated with conventional thyristors in regards to surge(More)
