Methods for coating a substrate and methods of shaping a workpiece comprise formation and use, respectively, of a surface or substrate comprising a first phase selected from nitrides, carbides. In accordance with some embodiments, transfer may result in the presence of island-like oxide structures on the handle wafersubstrate, each having a defect-free island of the lattice-mismatched semiconductor material embedded within its upper surface. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. A volume adjustment unit is electrically connected to the signal transmission unit, the cellular phone receiving unit, the sound device receiving unit and the speakers, and adjusts a volume of sound generated through the speakers. The vibrator unit includes a piezoelectric vibrator that is bonded to the diaphragm portion. Cradling or clamping wheel chock assemblies can be utilized to cradle or clamp the motorcycle’s wheel.
