A transmission line includes a dielectric substrate having first and second principal surfaces. The console includes an assembly housing adapted to mount against an interior surface of the vehicle. At least a portion of the lower cylindrical enclosure or upper cylindrical enclosure is made of a polyolefin elastomer foam. The shelving unit may also include a stop for inhibiting movement of hangers along the rod and past the stop, andor a connector for coupling the shelving unit to a rod of another shelving unit for allowing movement of hangers between the rods. These microspheres are insoluble in common organic solvents, but are readily dispersed into polycarbonate-based charge transport formulations. Labels may comprise shape-encoded particles which may be coupled to ligands such as DNA, RNA and antibodies, where different shapes are used to identify which ligand are present.
