Although power circuit breakers are designed primarily to interrupt heavy inductive short-circuit currents, system growth in recent years has produced a greatly increased requirement of interrupting relatively lighter currents which are associated wi

Undesired voltages often accompanied by phase reversal have been experienced1,2 on distribution systems after the opening of 1- or 2-phase conductors. The mere opening of phase conductors on a 3-phase system will not necessarily result in undesirable

Performance on the Wechsler Adult Intelligence Scale was followed over two 5- to 6-year intervals for essential hypertensive Ss (EH; n = 22) free from medical complications and for normotensive Ss (N; n = 20). EH were treated with adrenergic beta-blo
