The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for transmitting a control channel in a wireless communication system that supports multi-cell cooperative communication. The liquid deposition apparatus comprises a drop emitter containing a positively pressurized liquid in flow communication with a linear array of nozzles for emitting a plurality of continuous streams of liquid having nominal stream velocity vj0, wherein the plurality of nozzles have effective nozzle diameters D0 and extend in an array direction with an effective nozzle spacing Ly. The outer cover comprises a first side panel which is located in the first side portion of the absorbent article and a second side panel which is located in the second side portion of the absorbent article. For example, the displacement member partitions an inner space of the header tank into two space parts when both the vapor-compression refrigerant cycle and the Rankine cycle are operated, and does not partition the inner space when only one of the vapor-compression refrigerant cycle and the Rankine cycle is operated. When the signal from the PC unit is supplied to the display device, the power source power distributor supplies the electric power to both the PC unit and the display unit, while when the signal from the other device is supplied to the display device, the power distributor supplies the power to the display unit. The administration of nucleic acid may in alternative embodiments be performed before, simultaneously as or after the introduction of the device in a body.
