Compositions are provided that contain a TRPV1 agonist, such as capsaicin, and a solvent system. The metal-filled vias are contacted with a thermoelectric cooler to remove excess heat from the semiconductor device or devices. An annular gate is fabricated around the vertical channel such that it partially or completely surrounds the channel. The distal tips of the tools are desirably configured to reduce the chance of transection of a biological unit, such as by including both cutting segments and blunt relief segments. The matching surfaces are fastened together by placing the matching surfaces together back to back whereby locating members are spaced apart a sufficient distance. The handle device includes a base portion configured to protrude from a top surface of the watersports board, and a handle portion attached to the base portion, wherein the handle portion is configured to be positioned offset from a longitudinal axis of said watersports board.
