The present invention relates to new crystalline molecular sieve SSZ-47B prepared using a N-cyclopentyl-1,4-diazabicyclo2. The driving side rotational member includes a housing formed into a closed-end cylindrical shape and having a bottom portion formed to close one end of the housing in an axial direction thereof and an opening portion formed to be opened at the other end the housing in the axial direction thereof, and a plate member closing the opening portion. One plate has a number of small protuberances and the other plate a corresponding number of shallow pockets. Blade-tip measurements are processed through specialized algorithms to detect such asymmetry during operation, providing a real-time, non-destructive method of prediction. Multiple stage release profiles can be provided by providing multiple layers of matrices and fiber reinforcements, whereby different pharmaceutically active ingredients or genetic materials or different concentrations thereof, can be released according to the degradation profiles of the matrix and fiber reinforcment. The cover includes an opening that is configured to define a pair of flanges on either side of the opening.
