La0.67 Ca0.33 MnO3 thin films were investigated using nanosecond duration electrical pulses. It was found that strong (up to 30 kV/cm) electric fields significantly reduces the resistance of the film and shifts the peak in resistance vs. temperature dependence to higher temperatures. The results are discussed using a model based on fast spin and charge system response to electric field action o...

To investigate the dominant factors that allow a reproducible nuclear reaction in DPd systems, the initial electric resistance and the hardness of the Pd cathode have been examined for excess heat generation and the excess neutron emission in LiOD-Pd electrolysis cells. Two background (control) runs and one foreground run with the Pd cathode of high electric resistance and high hardness gave no...

The total electric resistance R is theoretically linearly increasing function of the conductive wire length L because the electric conductivity K or electric resistivity r is independent on L. It was found out that dependence of electric resistance R on L is highly nonlinear for yarns containing the conductive metal fibers. The main aim of this paper is creation of the simple mechanistic model ...

The electric resistance, sensitively dependent on the electronic structure and currently used to detect transformation temperatures in shape memory alloys, deserves attention also in the stress transformation domain. In fact, the electric resistance has already been investigated under increasing stress in the martensitic phase of several shape memory alloys: in this case a linear relationship i...

With the application of the articulated phase insulator, and the speed of electric locomotive rising, it is inevitable for the electric locomotive to adopt the technology automatic passing through the electric phase separation. However, when the locomotive passes the electric phase separation, a variety of overvoltages will be generated, such as the cut-off overvoltage and the closing overvolta...

We study the charge density distribution, the electric field profile, and the resistance of an electrostatically created lateral p-n junction in graphene. We show that the electric field at the interface of the electron and hole regions is strongly enhanced due to limited screening capacity of Dirac quasiparticles. Accordingly, the junction resistance is lower than estimated in previous literat...

There are two methods of applying heat by means of electric currents at present?by what are practically electric incandescent lamps, and by means of wires drawn from metals that have been designed not to increase their electrical resistance to any appreciable extent with a rise of temperature. With nearly all substances the electrical resistance of the substance increases in a certain definite ...

Thermally activated flux motion and specific electric resistance in Y358 were studied under different magnetic fields ranging from 0 to 15 kOe. Through investigating the broadening of normal-superconducting transition, we found that the thermally-activated-flux-motion model can describe the electronic effect near the superconducting transition temperature. By modifying this model, specific elec...

BACKGROUND Epithelial migration restores barrier function after superficial injury to any mucosa. The present study aimed to determine whether butyrate, important to colonic epithelial physiology in diverse ways, influences restoration of barrier function in the injured rat colon. METHODS Rat distal colon was transiently exposed in vitro to heat (55 degrees C for 10 sec) or to detergent (deox...
