A method and apparatus for treating for disposal oil-contaminated clay substrates such as drill cuttings from drilling with an oil-based mud. The cosmetic treatment method includes providing a composition comprising at least one corn peptidic hydrolyzate, as an active agent to stimulate hair growth, or reduce hair loss and applying it topically to an area having hair follicles. In a programming operation, the resistance of the phase change resistor is changed to at least one of a plurality of stages by an electric signal applied in a direction from the first electrode to the second electrode and an electric signal applied in a direction from the second electrode to the first electrode. A remotely located controller determines the configuration of the objects in response to the position information. Images to be displayed on the display unit are switched responsive to a rotated state of the second casing relative to the first casing.
