The subject matter described herein includes methods, systems, and computer program products for determining an integrity measure of a game user using dynamic performance events. The effective concentration of hop acids was found to be dependent upon the type of fermentation medium used. The signals received on the contacts are analysed by an analysis circuit, then switched to address and data registers by a switch circuit. The invention further relates to a particular method for assembly of a filtration bag within a unit as above, a tool for tensioning bags, embodied to be suitable for the unit. The method according to one embodiment includes receiving two or more transmission blocks through two or more downlink component carriers from the BS; and transmitting information on a number of ACK responses among ACKNACK responses corresponding to each of the two or more transmission blocks through a single uplink component carrier to the BS.
