A radio activated danger warning system in the form of a radio activated bush fire warning system 10 comprising transmitting means 12 for transmitting a coded signal to a plurality of geographical zones 14, each zone 14 having a unique code assigned to it. The metal germanosilicide layer is electrically connected to the sourcedrain pattern. Further, a channeling member is disposed generally adjacent to the electromagnet and has a radial surface disposed adjacent to the rotor radial surface. Operating conditions for the disclosed carbon dioxide treatments preferably involve sparging carbon dioxide gas into the substance until the composition is saturated with carbon dioxide and is conducted at pressures below about 5 MPa; at temperatures of less than or equal to 30\xb0 C. The connector-alignment collar is placed around a first electrical connector on a first circuit board.
