Memory effects in conducting polymers
Physical Review Letters, 1989The kinetics of electrochemical doping of polyaniline films has been studied using in situ ESR experiments. It has been found that the kinetics and the doping level achieved during a potential-reading step depend on the previous electrochemical events undergone by the sample.

Concealed conduction effects in the atrium
IEEE Engineering in Medicine and Biology Magazine, 2009A one-dimensional (1-D) model of the atrium together with the sinoatrial (SA) and atrioventricular (AV) nodes is presented in this article. The two nodes are each modeled by 15-element, diffusively coupled, modified van der Pol oscillator chains, while the atrium tissue is represented by a 90-element chain of diffusively coupled FitzHugh-Nagumo (FHN ...

Conduct Disorder and Neighborhood Effects
Annual Review of Clinical Psychology, 2018There has been a considerable amount of scholarly attention to the relationship between neighborhood effects and conduct disorder, particularly in recent years. Having said this, it has been nearly two decades since a comprehensive synthesis of this literature has been conducted.

Effects of Dobutamine on atrioventricular conduction
American Heart Journal, 1975Dobutamine, a new beta-stimulating catecholamine, has been investigated in terms of its effect upon atrioventricular conduction. Bundle of His recordings were obtained on six patients in basal conditions and with right atrial pacing at rates of 100, 120, and 140 per minute.

The effect of ischemia on nerve conduction
Experimental Neurology, 1967Abstract There has been some discrepancy in the literature regarding the effects of ischemia on peripheral nerve conduction: Are the more slowly conducting fibers or the more rapidly conducting fibers more sensitive to an ischemic environment? A technique of studying the compound action potential (AP) from more than one segment of the in vivo canine ...

The Two-Band Effect in Conduction
Proceedings of the Physical Society. Section A, 1952For an isotropic two-band conductor in a transverse magnetic field, the various galvanomagnetic, thermomagnetic and thermoelectric coefficients are derived by elementary arguments in terms of those of the individual bands. The expressions are applicable to quasi-free electrons of any degree of degeneracy: for fully degenerate electrons they reduce to ...

Conducting Effective Tailgate Trainings
Health Promotion Practice, 2008The California Department of Health Services' Occupational Health Branch and others have identified the construction industry as being at high risk for injuries, illnesses, and fatalities. Effective tailgate trainings (brief job site safety meetings) can be a powerful tool to promote hazard awareness and safe work practices. The authors found that many

Effective thermal conductivity of composites
International Journal of Heat and Mass Transfer, 2014Abstract The paper employs a theoretical model to evaluate the thermal conductivity of composites under two thermal assumptions which allow to solve the heat conduction equation. The composite is made of a ceramic-silica matrix and a fiber reinforcement. Three different materials are investigated as reinforcement, i.e. asbestos, steel and copper. The

Correlation effects in hopping conductivity
Physical Review B, 1989We introduce an alternative mapping of the hopping problem onto a random resistor network, which takes into account correlations among the occupation probabilities of different sites. The effect of correlations on the low-temperature conductivity of one-dimensional chains in the nearest-neighbor and variable-range-hopping cases is investigated by ...

Transient effect in conducting ring
Archiv für Elektrotechnik, 1988A numerical method of calculation of the current density in a a thin conducting ring generated by external transient field is presented. The method discussed is based on the integral formulas. Current density within ring as a function of position and time is given. An experiment verification is presented.
