A method and device for cooling an electronic component during its manufacture, repair, or rework is disclosed. A radial gap is located between the stator vanes and the rotor vanes such that rotation of the rotor causes the stator and rotor to co-operate to provide a system for moving fluid longitudinally between them. The invention also relates to recombinant vectors, transformed host cells and nonhuman transgenic mammals comprising a nucleic acid which regulates the transcription of the ABC1 gene or an abovementioned nucleotide construct, as well as methods for screening molecules or substances which are capable of modifying the activity of the regulatory nucleic acid for the ABC1 gene. The support rack is provided with two handles and has a first end inserted into one of the two semi-spherical bodies, and a second end provided with an arcuate catch plate. The requesting entity is granted or denied the requested access to the resource associated with each command if a determination has been made that each condition of at least one specified condition has or has not been satisfied, respectively.
