The galvanic corrosion behavior of Alloy 690 coupled with magnetite has been investigated in an alkaline solution at 30 °C and 60 °C using a potentiodynamic polarization method and a zero resistance ammeter. The positive current values were recorded in the galvanic couple and the corrosion potential of Alloy 690 was relatively lower. These results indicate that Alloy 690 behaves as the anode of...

THE relation of the cerebral cortex to the activity of the sympathetic nervous system is not yet fully clear. The clinical and experimental observations, which have recently been reviewed by Kennard (1937), have been conflicting, and there have been few quantitative determinations of the effects of cortical stimulation and ablation upon the functions of the human sympathetic nervous system. Man...
