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
The A Word their otolaryngologist refers Joe to a specialist who diagnoses him with autism. The story then follows how the dysfunctional family, including Rebecca (who feels invisible), Eddie and Nicola (who are coping with their own relationship problems) and tactless grandad Maurice cope with Joe's situation and their own apparent social disorders.
