A junctionless semiconductor device having a buried gate, a module and system each having the same, and a method for forming the semiconductor device are disclosed. The anti-calculus composition comprises a pyrophosphate and a tripolyphosphate in a pharmaceutically acceptable carrier. 5 to 5 parts by weight of an organic peroxide and 0. One or more parameters of the conductive wire assembly are selected such that the assembly has a predetermined impedance when submerged in oil within the PBOF hose. The rocker is coupled to and moveable relative to the main body. The table saw includes a brake positioning system configured to adjust the position of the brake mechanism to maintain the brake mechanism in an operative position relative to the blade as the blade is raised and lowered.
