An electric device includes a main body, a supporting crutch and a pivot mechanism connecting the body to the crutch. The method comprises feeding the animal a diet supplemented with gamma-tocopherol in an amount effective to improve the tissue quality. The rotatable device is configured to receive a first bit device detachably mounted in the rotatable device for powering rotational movement of the first bit device. The luminous flux reflected by the main mirror reaches an eyepiece lens through a focusing glass and a pentaprism. A heating device, which may include a plurality of heating elements including laser diodes, is scanned across the recording medium and the temperature of the heating element corresponding to a given picture element determines the recorded color for that picture element. These differences are then journaled as if they were write commands.
