<p>Vegetable oils have been an alternative to mineral oil for oil-immersed transformers due concern on less flammable, environmental-friendly, biodegradable, and sustainable resources of petroleum-based insulating oil. This paper presents the effect electrical discharges (200 up 1000 discharges) under 50 Hz inhomogeneous electric field properties (acidity, water content, breakdown voltage...

Bioimpedance, which uses resistance to electrical current in comparing the composition of fluid compartments, could potentially be used as a tool to diagnose lymphedema. There is minimal information about the technical and diagnostic performance of bioimpedance testing in the diagnosis (surveillance) of secondary lymphedema; especially for subclinical disease. In addition, there are no data fro...

An overview of general phenomenology and proposed physical mechanisms of large scale electrical discharges termed ‘blue jets’ and ‘gigantic jets’ observed at high altitude in the Earth’s atmosphere above thunderstorms is presented. The primary emphasis is placed on summarizing available experimental data on the observed morphological features of upward jet discharges and on the discussion of re...

This work is devoted to the study of the electrical characteristics of microhollow cathode discharges (MHCD) at moderate to high pressure in argon and air for different geometries. High-pressure glow discharges can be operated in MHCD devices with μm electrode spacing. Experiments have been performed to determine the so-called Paschen curves, i.e. the dependence of the breakdown voltage on the ...

This review is intended to give an overview of recent results on plasma-assisted ignition and combustion. The influence electrical discharges combustion processes introduced, the excited species radicals present in large quantity plasma are detailed. A description theoretical problems related modeling given, elucidating role states enhancing reaction rates. Then some experiments reported, focus...

BACKGROUND Genetic rat models for childhood absence epilepsy have become instrumental in developing theories on the origin of absence epilepsy, the evaluation of new and experimental treatments, as well as in developing new methods for automatic seizure detection, prediction, and/or interference of seizures. METHOD Various methods for automated off and on-line analyses of ECoG in rodent model...

Population spikes vary in size during prolonged epileptic ("ictal") discharges, indicating variations in neuronal synchronization. Here we investigate the role of changes in tissue electrical resistivity in this process. We used the rat hippocampal slice, low-Ca(2+) model of epilepsy and measured changes in pyramidal layer extracellular resistance during the course of electrographic seizures. D...
