Role of copper in continuously transposed conductors

This article explores the critical importance of the proper selection of copper, one of the key raw materials used in the making of continuously transposed conductors for extra high voltage power transformer windings. Windings are one of the most vulnerable components of a power transformer in terms of withstanding various types of electrical disturbances that lead to transformer failure. They have to satisfy complex transformer requirements, but also fit into the economics reasonably well in order to be competitive. Therefore, the expectations about the transformer health and longevity will largely depend on the right choice of its active components and the materials used in their production

A Trichinella murrelli infection in a domestic dog in the United States

Trichinella murrelli infection was diagnosed in a naturally infected Beagle bitch from VA, USA, where encapsulated larvae were found in histological sections of several skeletal muscles. A laboratory reared dog fed infected muscles resulted in viable muscle larvae that were subsequently infective to Swiss–Webster mice. Multiplex PCR using larvae from the experimentally infected dog demonstrated two distinct bands migrating at 127 bp and 316 bp which together are diagnostic for T. murrelli; the isolate was assigned the ISS code: ISS1608 by the International Trichinella Reference Centre. This is the first report of T. murrelli infection in a companion animal
