Corona discharge Corona discharge A corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is electrically charged. Spontaneous corona discharges occur naturally in high-voltage systems unless care is taken to limit the electric field strength. A corona will occur when the strength of the electric field (potential gradient) around a conductor is high enough to form a conductive region, but not high enough to cause electrical breakdown or arcing to nearby objects. It is often seen as a bluish (or other color) glow in the air adjacent to pointed metal
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
