Electrical Phenomena in Nerve
The action of a number of agents, which may be classified as "stabilizers" and "unstabilizers" on the electrical oscillations and after-potentials in the squid giant axon has been examined. The effects on the spike, "positive overshoot," and "potassium potential" were also observed, but where possible concentrations were employed which left these phenomena unaltered. Veratrine augmented the osc...
متن کاملIntermittency Phenomena in Electrical Connectors
Fretting is known to be a major cause of contact deterioration and failure, particularly in tin-plated contacts. During fretting the contact resistance generally increases slowly with time. Superimposed on this slow increase in contact resistance are rapid changes in contact resistance within fractions of a second, called intermittences or short duration discontinuities. Although intermittences...
متن کاملElectrical Transport Phenomena in Molten Salts
The equivalent conductivity of molten salts containing more than two ion constituents will be discussed using the equivalent fractions (Äquivalentanteile). The ionic conductivities of the ion constituents follow from this equivalent conductivity and the transport numbers. The electrical transport phenomena are referred to the idealized ionic melt which is defined by the limiting values of the i...
متن کاملElectrical phenomena in amorphous oxide films
Thin layers of insulators, from 100 A to 20 000 A thick, have a number of interesting electrical properties. These properties include forming, which is a profound and essentially permanent change produced by an electrical field, and, after forming, differential negative resistance together with switching and memory phenomena. Electroluminescence and electron emission also occur. These features ...
متن کاملElectrical Phenomena on the Moon and Mars
The Moon and Mars represent intriguing and divergent case studies where natural electrical processes may occur in environments beyond our more familiar terrestrial experience. The windy, Aeolian environment of Mars likely produces substantial electrical activity via the tribo-electrification of individual dust grains that occurs during atmospheric disturbances. While there may be some analogies...
