The present invention is directed to a DRAM circuit that implements a self-refresh scheme to substantially reduce its power dissipation level during self-refresh operations. The proposed enhancement operations may be presented to an operator for verification or, if the enhancement operations are determined to have a threshold level of confidence, may be automatically applied to the print job. The second insulating member includes a depression having peripheral ribs on an opposite face to the sealing plate. The threaded distal portion extends from the unthreaded eccentric portion to the distal end of the bone screw. A preferred embodiment is the use of the identified compounds as additives in coffee and coffee-flavored foods, beverages and medicinals. Use of the device of the present invention to produce foams makes it possible to produce foams having improved surface quality at higher production rates than were previously possible.
