A spread spectrum transmitter provides delays having different magnitudes to spread spectrum signals for a plurality of channels, and multiplexes the SS signals to generate transmission multiplex SS signal. The low power entry circuit receives a plurality of control signals which are provided to a command decoder, and generates a low power signal indicating a low power consumption mode where a refresh operation is prohibited. Also provided is a fusion protein, which includes a non-oligomerizing fluorescent protein linked to at least one polypeptide of interest. The front acoustic terminal is displaced ahead of the front surface of the microphone case, and the directionality varying member is in close contact with the outer circumferential surface of the microphone case. We have developed a blood test using mycobacterial catalase-peroxidase that has a high positive predictive value for confirming a diagnosis of sarcoidosis. and in the presence of halide ions and at least one strong acid that is not a hydrohalic acid, and finally heating the mixture to a temperature in the range 70 to 160 C.
