A prosthesis for the replacement of multiple diseased or traumatized spinal facets comprises a portion that replaces at least a bony portion of the facets to be replaced and where the prosthesis attaches to the vertebra in a manner that does not require attachment to, or abutment against, the lamina. In an embodiment, a method applies a first resource management strategy to a first resource associated with a first processor and executes an instruction block in a first processor. Consequently, all light beams can be utilized as the final outgoing light beams with no loss of light. In this method, the butyl methacrylate, butyl acrylate, and styrene are combined with water to establish a first reaction blend. , numerical values or continuous dimension-dependent design rules.
