We investigated the frequency and duty cycle dependence of maximal electrically induced torque (MEIT) of the wrist extensors. Fifty hertz burst modulated sinusoidal alternating current (AC) in the frequency range 0.5-20 kHz was used, with duty cycles ranging from a minimum (one cycle) to maximum (co

✦ Synopsis
The dependence of the current yield of the electrochemical production of ferrate(VI) by anodic oxidation of iron was measured as a function of the frequency of alternating current, superimposed on the direct current; the ratio of the ac amplitude to the dc current was 2.6: 1 and the electrolyte was NaOH solution of a concentration of 560gdme3 at 20 and 30°C. The highest current yield was found at an ac frequency of 5 Hz.
