An AV Clip generated by multiplexing video and graphics streams is recorded on a BD-ROM. The anteriorposterior stem taper angle of the femoral stem component varies across its range of sizes. The resilient component includes a radially inwardly projecting sealing lobe for providing a compressive seal with the spigot end of a pipe, and a reinforcement portion of the rigid component is disposed between the sealing lobe and the pipe bell end to provide a radially non-compressible reaction surface against which the sealing lobe is compressed. A collaboration component assigns members to the team and roles for the assigned members. The meter valve slideably disposed on the sliding assembly between the upper and lower flanges.
