The invention relates to a method of identifying nuclear receptor controlled genes in specific tissues. Search results are combined from results from a plurality of indexes, each of the search results having an associated key field. A correlator determines location differences of the common features of the first and second images relative to the at least one navigation array and provides a displacement signal indicative of imaging device translation in two planar dimensions during an interval between the first and second images based on the location differences. Finally, the present invention also relates to a fluorescent PAEK material. The ignition override switch is open when the flag is in the first position to override operation of the vehicle ignition and closed when the flag is in the second position to allow operation of the vehicle. Means for Solving the Problems The inside of a contactor 1 is divided into a plurality of cells 22, 32 by partition walls and the respective cells 22, 32 become countercurrent contacting spaces of an upflow fluid flowing up in the contactor 1 and a downflow fluid flowing down in the contactor 1.
