The present invention relates to stable substantially non-aqueous, non-alcoholic, non-silicone, foamable carrier compositions comprising petrolatum or mixtures thereof, at least one foam agent, at least one propellant, and with and without the addition of an active agent. The device comprises a plurality of elongate wings, each of which has a length consistent with the length of a stent to be deployed using the deployment device, the wings being arranged circumferentially about a central body which extends from, and is operable through, a catheter. The movable dish rack is moved from a treatment position in which the wash compartment is closed to an access position in which loading and unloading of dishes into the dishwasher is facilitated. Further, the Page Fault Handler is modified such that free memory pages are assigned to a process based partially on the proximity of the memory with respect to the processor requesting memory allocation. The adjustable spacers may be adjusted prior to exposure image modification by using an adjustment plate having openings to provide access to and adjustment of the adjustable spacers.
