The present invention relates to a new composition and medical implant made therefrom, the composition comprising a thick diffusion hardened zone, and preferably further comprising a ceramic layer. The system maintains proper positioning and alignment of system components without using connecting structures. The first layer and the fluid pathway of the second layer form a nozzle, and the nozzle has a cross-shaped cross-section. A substrate conveyor is disposed below the transport conveyor and conveys substrates in a conveyance path through the apparatus such that an upper surface of the substrates is opposite from and spaced below a lower leg of the transport conveyor. After the magnitude of the negative pressure produced in intake piping of the internal combustion engine exceeds a predetermined reference value, fuel supply into the remaining cylinder is started. Suture elements mounted to suture anchors are terminated in suture loops or tags, and associated stop members that in combination with visual coding provide suture identification, prevent accidental unmounting of suture from suture anchors, and reduce the number of suture legs requiring active management during complex arthroscopic repairs.
