The improved microphone with the removable connection to the phantom power supply facilitates the setting and provides elimination of the forgetful operation of switch-off, in e. The invention also includes assays for identifying protease inhibitors and protease modulators, determining the amino acid sequence of a protease cleavage site for a known protease, identifying and cloning a protease whose cleavage site is known, and rapidly identifying a form of a protease exhibiting increased activity relative to a control protease. An initial transcribed value and corresponding recognition score are assigned to each utterance. An electrode paste is coated in a predetermine pattern on the thus-produced ceramic green sheet to form a sheet provided with an electrode. The errors from the inherent inaccuracy of the position and shape of alignment features are thereby minimized.
