Apparatus and a method for handling messages that relate to a cell other than the currently operating cell in universal mobile telecommunications system user equipment are disclosed. Traditionally, pluripotent stem cells are cultured on a layer of feeder cells to prevent them from differentiating. A switching assembly is associated with each of the one or more transformers and is operative in a first position to connect the primary winding across the supply voltage, wherein a voltage of an opposite polarity is induced across the secondary winding. When ordinary sheet is conveyed, the sheet is passed above the upper surface of the special ribs so as to prevent generation of defective image caused by bending of sheet. The PTFE pellets so obtained may be used to prepare molded articles of PTFE. One system configured to inspect a specimen includes a first optical subsystem coupled to a broadband light source and a second optical subsystem coupled to a laser.
