A scheduler, scheduling method, and computer program product are provided for implementing Quality-of-Service scheduling of a plurality of flows with aging time stamps. The apparatus includes an axisymmetric streamline receiver and a support member. Uses of such polymeric materials include the formation of polymer electrolyte membranes, catalyst coated membranes and membrane electrolyte assemblies which may be used in fuel cells and the like. A method of communicating data in a wellbore is also provided. The improvement is the fusion of a sequence-non-specific nucleic-acid-binding domain to the enzyme in a manner that enhances the ability of the enzyme to bind and catalytically modify the nucleic acid. The at least one retaining tab and the at least one spring member are configured to compressively sandwich a portion of the panel therebetween.
