The present invention is directed generally to activating gene expression or causing over-expression of a gene by recombination methods in situ. The bus interface system includes a master bus controller and a slave bus controller coupled to a bus line. The other egress network processing units are configured for these particular sets of packets to be in the non-active mode, and hence, will correspondingly drop these particular sets of packets. There is also provided a method of stabilizing and maintaining dispersion of particulates in a cosmetic composition. The filtered light has primary wavelengths no longer than that of blue light. Heavy crude oil having substantial amount of asphaltene and heavy components is mixed with highly waxy crude oil having large amount of paraffinic components and water to decompose asphaltene compounds and remove sulfur, nitrogen, and metal containing substances under supercritical conditions.
