The invention discloses a fast booting method for a mobile communication device. In the method, the mobile station measures receiving strengths of pilot channels transmitted from the first BSS and the second BSS, and transmits the measured receiving strengths to the BSC through the first BSS and the second BSS. Thus, the partition wall is prevented from damage andor deformation even if a tab or the like strikes against the partition wall. The sediment containers may be preformed or they may be formed just prior to their placement. The laser system also includes an optical modulator that is located within the shared path. The new compounds of the present invention comprise activation sites that allow for specific catalyst design.
