Ionic conduction and electrode polarization in a doped nonpolar liquid.

Electrical current versus potential relationships were measured for solutions of dodecane containing the charge control agent poly(isobutylene succinimide) (PIBS) at various concentrations. Both one-dimensional (parallel planar electrodes) and two-dimensional (strip electrodes) fields were studied. The initial current was proportional to the applied voltage for both electrode configurations.

Anatomic correction of polysyndactyly of the fifth toe fused with the fourth toe.

A new surgical technique for correction of polysyndactyly with the fifth toe fused with the fourth toe was devised. The technique consists of the creation of a dorsal rectangular flap on the dorsum of the syndactyly web for the new fourth web, making a medially based plantar rectangular flap on the plantar surface of the fifth toe, and a sixth toe-tip-based rectangular hinge flap to reconstruct the lateral side of the fourth toe and medial side of the new fifth toe, respectively. All suture lines are intended to be located in the transition of the plantar and dorsal surfaces of the web and digit.

Two-particle dynamics on an electrode in ac electric fields.

The relative motion between pairs of negatively charged latex particles 9.7 microm in diameter and deposited on an electrode was measured by optical microscopy and image analysis. At an rms field of approximately 30 V cm(-1), the two particles moved toward each other at frequencies below 500 Hz, but they separated at 1000 Hz.
