Electrodeless conductivity

Talanta, 1989
Electrodeless conductivity is a technique for measuring the concentration of electrolytes in solution and utilizes a probe consisting of two toroids in close proximity, both of which are immersed in the solution. In special cases, the toroids may be mounted externally on insulated pipes carrying the solution. One toroid radiates an alternating electric

Conductive keratoplasty

Current Opinion in Ophthalmology, 2007
Conductive keratoplasty is a noninvasive, in-office procedure for the correction of hyperopia, hyperopic astigmatism, and management of presbyopia. It serves as an alternative to laser-based refractive surgery with essentially no intraoperative or postoperative complications.In the past decade, photorefractive keratectomy and laser in-situ ...

Conducting Polymers: Electrical Conductivity

2007
Abstract : While undoped polymers are insulators, doped conducting polymers have conductivities comparable to conventional metals and semiconductors despite their polymer chain structure. Models for the doping induced insulator-metal transition and the metallic conductivity of conducting polymers are introduced.

Conductive Education

Journal of Paediatrics and Child Health, 1991
ABSTRACTOver the past 5 years, there has been increasing interest in the application of principles of Conductive Education, also known as the Peto method, to treat children with cerebral palsy. In 1945 Andras Peto, a Hungarian physician trained in rehabilitation and psychiatry, began his work with motor disordered children.1 In 1952 he opened what was ...

Intrinsic conductivity of conducting polymers

Synthetic Metals, 1988
Because the charged dopant ions are spatially separated from the quasi-one-dimensional conduction path in conducting polymers, resistive back scattering is suppressed. In the case of high molecular weight and relatively few sp3 defects, even relatively weak interchain coupling is sufficient to avoid one-dimensional localization; this leads to coherent ...

Concealed Conduction

Cardiology Clinics, 1983
To analyze all but the most simple of cardiac arrhythmias, one must understand the concept of concealed conduction. The numerous electrocardiographic manifestations of concealed conduction, some illustrated in this discussion, remain interesting models of basic electrophysiologic phenomena.
