The present invention provides a wound dressing comprising a tessellated water-soluble molding matrix comprised of a polymer selected from the group consisting of polyvinyl alcohol, gelatin, and mixtures thereof and a 1,1-disubstituted ethylene monomer. The communication interface may receive a multicast stream that includes a frame. First and second gates are spaced from one another in a second direction surrounding a portion of the channel to allow for application and removal of a gate voltage. The RNC then adjusts a transmission power offset of the DL EU signaling channel to be used in determining transmission power level of the DL EU signaling channel at the Node-B based on the EU transmission failure statistics. The apparatus can be used on a variety of different terrains, including inclines and declines and can pick up lumber from a wide radius around the apparatus and from a number of ground conditions including rocky, muddy and wet ground.
