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 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
