A control panel adapted to be attached to a main body of an image forming device is disclosed. The processing apparatus further includes an integral microprocessor for calculating the respective specific gravities of the liquid and vapor portions of the mixture based on the operating pressure, and then computing the density-compensated liquid level in the vessel based on such calculations of specific gravity and the differential pressure. A tail end is equipped with a bistable OFF and ON switching function and with a momentary ON switching function unified into one electric toggle switch having a stable OFF position, a stable ON position, and a momentary ON position. The point at which the platform frame and lifting frame make contact with the ground provides support for applied loads on the platform member, thereby reducing stress and strain on the frame of a vehicle. In a variation, a single point value selector is used and the random indicator generator designates an integer that determines a predetermined operation to be performed upon the point value selector to yield at least one point for the craps game. In an embodiment, the invention includes a method for increasing feed intake of an animal after a post-receiving stressful event comprising administering an effective amount of a composition comprising saponins to the animal.
