Brush discharge plastics. The ability of an electrical discharge to cause an explosion in flammable atmospheres is measured by the "effective energy" of the discharge. The effective energy of brush discharges is 10-20 mJ, much larger than that of corona discharges 0.1 mJ. Therefore, brush discharges are considered an explosion hazard, while corona discharges are not. Brush discharges can occur from charged insulating plastics (for example polythene) to a conductor. Brush discharge A brush discharge is an electrical disruptive discharge similar to a corona discharge that takes place at an electrode with a high voltage applied to it, embedded in a nonconducting
Latin word order "nobody has yet succeeded in unifying the insights of all the different scholarly approaches to the fascinating and peculiar problem of Latin word order". In his view an approach which combines the various schools of thought on Latin word order "may succeed in finding a more satisfactory solution". Several recent books, such as those of Panhuis and Spevak, have analysed Latin sentences from a pragmatic point of view. Syntactic approaches traditionally analyse a sentence into Subject and Predicate, but a pragmatic analysis considers a sentence from the point of view of Topic and Focus (or Theme and Rheme, as Panhuis
