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 a sentence, therefore. Other words, such as "fere" "approximately" and "etiam", are frequently enclitic: In the phrase "ne ... quidem" "not even", the word "quidem" generally follows the first word of the emphasised phrase, rather than the whole phrase: Personal pronouns such as "me" "me" and "mihi" "to me" can have weak and strong forms in Latin. When weak they tend to be found early in the sentence, either after the first word (which can be a conjunction such as "cum" "when" or "et" "and") or after an enclitic such as "enim", if present: Contrast sentences like the following, where
