Corona discharge with a discharge current of a few hundred microamperes can blow out a small candle flame within about 1 cm of a discharge point. A pinwheel, with radial metal spokes and pointed tips bent to point along the circumference of a circle, can be made to rotate if energized by a corona discharge; the rotation is due to differential electric attraction between the metal spokes and the space charge shield region that surrounds the tips. 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
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).

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.
