A fresh attempt to develop a self-consistent description of the retrograde motion of cathode spots on volatile cathodes is undertaken. Three potential mechanisms of effect of transversal magnetic field on the distribution of parameters in the spot ar

There are several hundreds of spots operating simultaneously on cathodes of vacuum arcs in high-power vacuum circuit breakers. In this work, the spot distribution along the contact surface is simulated by means of an approach that is based on the con

A model of cathode spots in high-current vacuum arcs is developed, with account of the plasma cloud left over from a previously existing spot, all mechanisms of current transfer to the cathode surface, including the contribution of the plasma produce

Ethyl glucuronide (EtG) in urine is considered a marker of alcohol consumption. We present a case of a false-positive immunological EtG screening result due to excessive isopropyl glucuronide excretion in urine of an alcohol-dependent patient with a

When a transversal magnetic field is present, current spots on arc cathodes made of volatile metals move predominantly in the anti-Amperian, or “retrograde”, direction; a phenomenon of high theoretical interest and importance for applications. A

Cathode attachment of high-current vacuum arcs, e.g., those in high-power vacuum circuit breakers, represents an ensemble of several hundred of spots operating simultaneously. A natural alternative to tracing individual spots is to employ the concept
