The present invention provides for modified forms of anti-CD52 antibodies with reduced numbers of potential T-cell epitopes that are expected to display decreased immunogenicity. The motor covers and motor housing are designed to provide direct increased airflow to the motor stator, and coil windings to provide better airflow through the motor resulting in improved cooling. Also included in the polishing device is a slurry supply line adapted to supply the polishing slurry from the source of polishing slurry to the polishing pad. The light path intersects the reactant stream path at a reaction zone with a product stream path continuing from the reaction zone. The silicone monomer of the present invention is represented by the formula or :. The E-mode FET further comprises a p+ III-V semiconductor layer disposed over the second semiconductor layer and a depolarization layer disposed between the second semiconductor layer and the p+ III-V semiconductor layer.
