Excess fluoride ingestion during childhood can cause mottling of the hard outer surface of the tooth (the enamel). Abnormal tooth enamel may be due to a diet containing insufficient vitamin D, as in rickets.
Creatine phosphate (CP), which is stored in skeletal muscles, donates a phosphate to ADP to produce ATP: ADP + CP â Â© ATP + C. No carbohydrate or fat is used in this process; the regeneration of ATP comes solely from stored CP.
Stored program control (SPC) is a telecommunications technology used for telephone exchanges controlled by a computer program stored in the memory of the switching system.SPC was the enabling technology of electronic switching systems (ESS) developed in the Bell System in the 1950s. trial system with stored program control was installed in Morris, Illinois in 1960. It used a flying-spot store with a word size of 18 bits for semi-permanent program and parameter storage, and a barrier-grid memory for random access working memory.
