An apparatus and method for reliability testing an electrical connector for an unacceptable propagation delay. The metal gate is located on a substrate and in a first dielectric layer, wherein the metal gate includes a work function metal layer having a U-shaped cross-sectional profile and a low resistivity material located on the work function metal layer. Compositions adapted specifically for post surgical joint lavage or treatment andor prevention of inflammatory arthritis, osteoarthritis andor degenerative joint disease are also provided. Two clamp members are inserted in the through hole of the ratchet wheel and each have an extension.
