OBJECTIVE To evaluate results of a prospective study of pregnancies in which early amniocentesis with the filtration technique was performed at 10-13 weeks' gestation (mean 12.3 weeks' gestation). METHODS 123 singleton pregnancies in which early amniocentesis with the modified filtration technique was performed at 10-13 weeks' gestation (mean 12.3 weeks'(More)
The effect of hydrogen implantation on the<tex>I(V)</tex>characteristics of lateral polysilicon p-n junctions is reported. After implantation with hydrogen and annealing at 400&#176;C, a moderate decrease in the forward current and a large decrease in the reverse current is observed. In addition, the reverse breakdown voltage is increased. Best results were(More)
