This invention relates to an antimicrobial composition comprising an antimicrobial compound and a polyethylene-polyvinylalcohol copolymer. In an example method, a processor instruction proxy stub associated with one or more processor instructions is generated. An operating system to be used on the computer when accessing the volume is determined, and a compatible version of the storage control software is uploaded and installed on the storage control module. Due to coordination of the positions of supporting fingers with positions of the crests and valleys of modulation, the optical phase coherence is maintained along the Bragg grating, so that the spectral lineshape or filtering property of the Bragg grating is substantially preserved. The process permits the filling of high aspect ratio spaces without any voids or keyholes that may adversely impact the performance of the resulting device. The primary element is rotatable relative to the secondary element from a neutral position into a first position, in which the primary driver is supported only on the spring device, and from the first position onward into a second position, in which the primary driver is supported on the spring device and on the end block.
