Dental restorations are fabricated using metal powder. The present invention discloses a strip, a laser-induced epifluorescence detection device and a small scanner for the assay method. A serving radio network controller transmits a sequence of packet data units. The multiple cutting blades are rotatably mounted on an arm which is pivotally mounted on a shaft in groups, being driven by an electrical or like motor, all of which are mounted onto a platform positioned adjacent to the log to be cut.
