A method for partially treating a water-repellent glass sheet is disclosed which comprises irradiating part of a water-repellent glass film, formed on the water-repellent glass sheet, with a stream of plasma jets generated by a plasma jet irradiating gun. In one aspect, a method for processing a computer-based material is provided. In addition, the present invention is directed to a method for treating patients with dialysis dependent renal failure with creatine compounds and to provide a variety of significant health benefits and improvement of life quality parameters for dialysis patients. The solid state light source end-of-life indicator may emit light upon receiving an end-of-life signal from an end-of-life detection circuit, which detects when the lamp is at an end of its life. A control unit, when assigning a communication channel according to spatial multiplexing to a mobile station, allocates a communication channel in which a reception timing difference between the new mobile station and all mobile stations communicating is equal to or exceeds a threshold value.
