The present disclosure relates to therapeutic compositions comprising substituted imidazoliums having multiple acidic groups. The apparatus includes a supply assembly configured to maintain and selective dispense a first precursor and a second precursor, a mixing assembly configured to mix the first and second precursors, and at least one catalyzing element including a transition metal ion to aid in the polymerization of the first and second precursors. The core may be frozen at any desired temperature, for any desired duration. Addressing the hardware IO control block stored in the one page includes using a tag supplied by a reconnecting SCSI target as the second portion. The invention further relates to a user equipment and a network entity operable to implement such a method. The input buffer includes an output terminal and a first test mode input terminal adapted to disable the output terminal in response to a first test mode signal.
