The present invention provides machinable calcium phosphate bone substitute material implants having mechanical properties comparable to those of natural bone. The assembly includes a tibial base trial adapted to be positioned on a surgically-prepared proximal end of a patient’s tibia, a base fastener, and a stem adaptor secured to the base fastener. This invention further relates to corn seeds and plants produced by crossing the inbred plant 5750 with another corn plant, such as another inbred, and to crosses with related species. Each particular hybrid circuit can interchangeably perform as either a logic circuit or an interconnect circuit in the configurable IC. The first device wafer is bonded to an etched substrate wafer to create a suspended diaphragm and boss, the flexure of which is determined by an embedded sensing element.
