Compositions and methods for the dissolution of a microbial biofilm are provided, where the method comprises contacting a microbiofilm with an effective dose of a curcumin derivative as a biofilm inhibitor. The IO circuit is coupled with a plurality of external pins, which provide external electrical connections for the communication of data and information between the resident circuitry and external circuits, such as system logic and other electronic devices to which the IC package is coupled. A driving unit is provided for each audio driver arrangement to generate a drive signal. One of the profiles is selected based on the comparison. The first radio frame is received prior to the second radio frame, and the transport format information indicates a transport format for transport channel data received in the first and second radio frames.
