The present invention provides methods for discovering agents that are effective in reversing epigenetic silencing by inhibiting the interaction of methyl-binding proteins with methylated genomic DNA. The compartment is for storing vehicle components such as car batteries. A plurality of lapping guides are also provided on the substrate between adjacent transducers. The user also enters information as to whether or not a number of specific control attributes have been implemented, and this information is used to calculate a control score. The surfaces of layers of the electron sources are bristled with the carbon nanotubes.
