In this paper we shall give the short transformation formulas by discussing transformation property of screw for space rotation, and also discuss transformation property for inversion.

Often the space issue is solved by using a log rotation policy, where logs are kept in several files that are truncated and overwritten as they reach a certain number of predefined bytes.

That's because the backward rotation puts more space between the black hole and the orbiting matter, leaving more room for magnetic fields to build up, the study authors say.
