A transmitter comprises resource mapping circuitry configured to map symbols from multiple control channels to transmission symbols in a base station of a wireless system. The endoglycanases may be one or more of EGI, EGII, EGIII and any functionally active derivative of any thereof. The image storage sheet pushing surface of the platen cover has a color other than colors which are ordinarily contained in image storage sheets. The present invention also refers to a method for manufacturing the above bamboo tile. The method includes determining a TDD ratio value of a number of time slots allocated for Forward-Link and a number of time slots allocated for Reverse-Link ; if the TDD ratio value is not an integer, grouping Mobile Stations into multiple groups and generating group index information; and transmitting, to the MSs, control information including the TDD ratio value and the group index information. A valve is disposed on the outer sidewall of the upper pot and is adjacent to the collecting tank.
