A method for manufacturing a crystallizable plastic material is disclosed. The case includes a rod cam portion for rotating the pushrod and a follower cam portion for rotating the follower. Detectors used in the UWB communication systems of the present invention utilize direct sequence spread spectrum technology for multiple access reception. An adhesive layer is interposed between the electrophoresis element and the first electrode. A plurality of cable assemblies are coupled to the drive assembly whereby each of the cable assemblies is actuated by the drive assembly when the drive assembly is rotated by the motor member. In one embodiment, the present invention provides one or more subsurface barriers capable of optimizing leaching operations.
