Semiconductor processing methods of forming integrated circuitry are described. More specifically, methods and compositions for treating attention deficit disorder and attention deficit hyperactivity disorders in adults and children as well as mild cognitive impairment and dementia are provided. A data acquisition circuitry is coupled to the sensor connection and has sensor-specific data acquisition circuits and at least one common data acquisition circuit. The invention also relates to a method of aligning a locking fastener in a plate at a desired angle relative to a bone by using a surgical guide having a key interface with the plate to position and align a pilot hole. The material 1 is then exposed to electron beam radiation andor ultraviolet radiation to cure the coating applied thereto. The device includes novel measuring, mixing and extrusion arrangements including: an automatic measuring cup; a way to continuously mix and extrude ingredients without intervening cleanings; a mixing and extrusion feed for handling different consistencies of ingredients; an integrated automatic cutter; motor cooling and extruded ingredient drying; as well as various safety devices.
