It is switched by staticinduction thyristor (SIThy) and is capable of generating pulsed current of ~9.7 kA for a time duration of ~1 ms. The SIThy switch module ismade that it can be controlled by an optical signal and it can be operated at elevated electrical potential. The experiments reported in this paperused two switch modules connected in series for maximum operating voltage of 3.5 kV. The experimental results have demonstrated a pulsedhigh-current generator switched by semiconductor devices, as well as the control and operation of SIThy for pulsed power application.展开更多

Bis(sulfosuccinimidyl)suberate (BS ), an impermeable cross-linker of band 3, inhibited NO2- transport, showing that anion exchange is affected by the association state of band 3 in the intact erythrocyte membranes. At the same time, the rates of glucose transport of both exit and entry declined. The amount of monomers of band 3 was decreased after treatment of the erythrocytes with BS3, but there was no change in GluTl according to the SDS-PAGE patterns. This demonstrates that band 3 and GluTl would be linkaged together in the erythrocyte membranes for the requirement of rapid and cooperative performance of physiological functions of the membrane proteins.展开更多
