Gastric resistant film-forming compositions are described herein. An outer rotor directly drives the shaft and includes an outer set of blades. The probe of the sampler assembly is extended through the track and into the ground, then retracted on each revolution of the track. During a hover mode, the device can be switched to sense one or more objects hovering over the device. Particular ancillary content can be personalized per consumer based on their past usage habits. Some embodiments include methods of forming NAND memory constructions.
