A micro-electromechanical integrated circuit device comprises a substrate; drive circuitry positioned on the substrate; and a plurality of elongate actuators. bi- or tri-cistronic polynucleotides of this invention include those encoding and co-expressing HIV gene products, genes encoding antigens unrelated to HIV, and immunostimulatory gene products, including but not limited to GM-CSF, interleukins, interferon and members of the B7 family of proteins which act as T-cell costimulatory elements. In response to the determination, the network device may configure a value of a cellular communication parameter utilized by one or both of the base stations. Embodiments may further operate to adjust the acoustic signal dead time circuitry power-down cycle, such as by adjusting acoustic signal frame rates. A filter in the second cyclone separation unit comprises a plurality of cyclone barrels.
