Does the electromotive force (always) represent work?

Shallow seismic reflection does not always work

Shallow seismic reflection has seen widespread use in a variety of environmental, groundwater, and engineering applications over the last 15 years. Seismic reflection, like any other geophysical technique, has reasonably well defined limitations. Besides the well-published resolution limitation, the effectiveness of the technique is strongly dependent, and in many cases controlled, by near-surf...

Electromotive Force in Electrochemical Modification of Mudstone

The Electromotive Force Produced by the Acceleration of Metals.

mecum, and the cutting is due to constriction in this ring, and the constriction to a change in surface tension, the work invo ved would require a minimum reduction along the inner surface of the ring of at least 383 dynes per centimeter. The bulk of evidence at hand seems to indicate that the paramecia are divided by the approach of two pseudopods and not by the constriction of a ring. To acco...

Universal electromotive force induced by domain wall motion.

The electromotive force induced by a moving magnetic domain wall in a nanostrip has been calculated theoretically and detected experimentally. It is found that the emf depends only on the domain wall transformation frequency through a universal Josephson type relation, which is closely related to the topological nature of the domain wall. Our experimental measurements confirm the theoretical pr...

Electric Currents, Membranes, and Biological Sources of Electromotive Force **

A description of steady-state material transfer through the barrier of the idealized physiological transfer unit, phase 1, membrane, phase 2,-two homogeneous phases separated by a complex barrier-based upon Newton's laws of motion has been outlined previously.1 The supposition was made that the conservative forces tending to drive the kinetic materials through a barrier b can be derived from di...
