A process for tinting of articles molded from a polymeric resin is disclosed. In particular, this invention relates to a method for creating a relational database by determining transcript levels of sets of genes expressed at predetermined stages in embryo development. The terminal has a mating portion forward extending beyond a front face of the insulated housing, and a pair of tail portions rearward extending beyond a back face of the insulated housing. Silicon nitride oxidizes to produce nitrogen oxides when heated. The supporting member is configured to pivot with the mounting member between a first position where the developing units are capable of supplying toner to the photosensitive drums and a second position where the developing units separate from the photosensitive drums.
