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 based, and establishing what nuances of meaning or emphasis could be obtained by using different word orders. Two major recent works on Latin word order, based on different approaches, are those of Devine and Stephens (2006) and Olga Spevak (2010). It is generally agreed that pragmatic factors play a major role in Latin word order, that is, factors such as topic and focus, contrast, emphasis, and heaviness. The topic (what is being talked about) often tends to come at the beginning of the sentence, and the focus (what is said about the topic) at the end or in penultimate position.
