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 nuances of meaning and emphasis. As the authors of "Latin Word Order", Devine and Stephens, put it: "Word order is not a subject which anyone reading Latin can afford to ignore. ... Reading a paragraph of Latin without attention to word order entails losing access to a whole dimension of meaning." One important advantage of studying word order in Latin is that it helps the reader to understand the author's meaning more clearly. Thus for example "complosit Trimalchio manus" doesn't merely mean "Trimalchio clapped his hands", but the initial verb implies a sudden action: "Trimalchio suddenly clapped his hands". In
