A polishing apparatus for polishing a workpiece comprises a polishing table having a polishing surface and a top ring for holding the workpiece and pressing the workpiece against the polishing surface. In order to define an optimally effective projectile-forming insert, even in a configuration of relatively small caliber, the seeking fused munition is of a full-caliber configuration without a casing. The waveguide apparatus can further include at least one composition processor adapted for changing at least one among an electrical characteristic and a physical characteristic of the waveguide apparatus by manipulating a volume of the conductive fluid and a controller for controlling the composition processor in response to a transmission line mode control signal. The material is shredded to form continuous net-like sheets having a marbled appearance defined by a first portion of the continuous net-like sheets with the low or non-glutenous material having a first overall color and a second portion of the continuous net-like sheets with the inclusion component having a second overall color different from the first overall color. During operation of the adjustment mechanism, rotation of the worm about the axis of rotation causes the first headband element and the second headband element to translate in opposite directions with respect to the worm, thereby adjusting a fit of the headgear. The olefin polymer composition comprises an olefin polymer containing 5 to 200 ppm of aluminum, as aluminum atom, 0 to not more than 1,000 ppm of a phenolic stabilizer and 50 to 2,000 ppm of a phosphoric stabilizer.
