The present invention provides a modified solid stick composition comprising a thermosetting plasticizer, a resin, a lubricant, a friction modifier, or a combination thereof. A first end portion of each connecting member extends through the front side member and is welded to both sides of the side member. The movable grip element is or can be connected to a force transmission element axially movable in the direction of a longitudinal axis of the tubular shaft. A locking plate member covers top and bottom sides of the zipper to secure the zipper during the off-season. Both modules are convection air-cooled without a requirement for forced air-cooling or water cooling. The RAIM algorithm is for determining an integrity risk in a global navigation satellite system by processing several ranging signals received from satellites of the GNSS.
