Effects of Pulsed Currents on Respiration and the Heart [PDF]
Occupational and Environmental Medicine, 1967 The effects on the respiratory and circulatory systems of rabbits of pulsed currents from two sources have been studied. The sources were an industrial high voltage test-set (source A) and an automobile ignition system (source B). When the fore-limb to fore-limb pathway was used, source A produced complete arrest of respiration at the highest output ...

Effect of Pulsed Current and Mold Material for Pulsed Current Sintering.
Journal of the Japan Society of Powder and Powder Metallurgy, 2001 The effect of a pulsed current on heating in a pulsed current sintering (PCS) was examined. When a graphite mold was used for the PCS, the heating rate of the mold did not depend on a frequency of a pulsed current. The heating rate of graphite applying pulsed current was larger than that of graphite applying direct current, because of the difference of
