A system-on-chip integrated circuit selectively gates clocks to individual modules corresponding to the state of a corresponding bit of a peripheral enable register. Respective head and foot hinges couple the middle cushion to the head and foot cushions for relative pivoting about respective transverse axes. The composition provides an effective increase in therapeutic and pharmacological properties in nutrition and diet systems. The composition is novel because it presents greatly decreased caking tendency as compared to OPA by itself, and preserves excellent flowing properties even after extended exposure to extreme temperature and humidity conditions.
