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 approval: He notes that the sentence would be ruined rhythmically if the word order of the last three words were changed to "comprobavit fili temeritas". What was apparently admired here was the clausula of "comprobavit" with its double trochaic – u – – rhythm; whereas "temeritas" would make a rhythm of u u u –, which Cicero says would produce an unsatisfying effect in Latin, despite being recommended by Aristotle. The 1st-century A.D. teacher of oratory, Quintilian, remarks that hyperbaton (switching words round) is often used to make a sentence more euphonious. He gives the example of the following sentence
