A movement activity is assessed in a movement assessment environment. The method comprises growing a plurality of one-dimensional nanostructures orthogonal to a first conductive layer. In another embodiment, the powder composition of the present invention may comprise a hydroxyl functional resin, preferably a polyester, mixed with the said silicone resin to aid in the adhesion of the coating to a substrate. The label side also has a plurality of partitions defined thereon. In a vertical embodiment, the surge tank includes a nozzle system disposed vertically therein that is part of the liquid port and that includes a nozzle member having a plurality of perforations disposed therethrough. Each of a plurality of antennas may be adapted to produce substantially plane waves at the device under test.
