The nonequilibrium properties of a driven quasi-one-dimensional superconducting ring subjected to a constant electromotive force (emf) is studied. The emf accelerates the superconducting electrons until the critical current is reached and a dissipative phase slip occurs that lowers the current. The phase-slip phenomena is examined as a function of the strength of the emf, thermal noise, and nor...
The fluctuation-induced Hall electromotive force, [deltaJ x deltaB]/nee, is experimentally measured in the high-temperature interior of a reversed-field pinch plasma by a fast Faraday rotation diagnostic. It is found that the Hall dynamo effect is significant, redistributing (flattening) the equilibrium core current near the resonant surface during a reconnection event. These results imply that...
From electromotive-force measurements of the cell without liquid junction: [Formula: see text]through the range 0° to 95° C, calculations have been made of (1) the standard potential of the silver-silver-chloride electrode, (2) the activity coefficient of hydrochloric acid in aqueous solutions from m (molality) =0 to m=0.1 and from 0° to 90° C, (3) the relative partial molal heat content of hyd...
The closest analog to propagated excitation of the heart is an electromotive surface. The width of the cardiac electromotive surface was 0.9 ± 0 . 1 mm and was remarkably constant. The mean epicardial surface component of voltage across the electromotive surface was 62.4 ± 7.2 mv with the chest closed and 74.1 ± 8.3 mv with the chest open. This 18.7^ increase is significant (P < .001) and sugge...
