Disclosed is an assay to quantify the amounts of catecholamine-O-methyltransferase protein in samples, such as extracts from cell cultures, body fluids, tissues, and environmental samples. More specifically, when an aspect ratio of a program is converted, letterboxing bars are used either along the horizontal or vertical edges. Additional transmission layers may also be transmitted each include a separate pilot generated and repeated in the first symbol and repeated offset form the separate pilot in an adjacent second symbol. The hand grip allows a user to arrange the hand grip and any attached support apparatus or supported equipment in a variety of configurations that facilitate hand-held to shoulder-carried configurations. In other embodiments, fragmentation of a polygon is adjusted based on the image intensities calculated at the simulation sites.
