Compounds of general formula, where R1 is selected from any one of phenyl, pyridinyl, thienyl, furanyl, imidazolyl, and triazolyl; where each R1 phenyl ring and R1 heteroaromatic ring may optionally and independently be further substituted by 1, 2 or 3 substituents selected from straight and branched C1-C6 alcyl, NO2, CF3, C1-C6 alkoxy, chloro, fluoro, bromo, and iodo. In general, the methods involve generating a first and second distinguishably labeled population of antibodies that reactive to the two samples, contacting the first and second labeled populations of antibodies with a plurality of antigens; and identifying any resultant antigens that are differentially bound by the first and second populations of antibodies. The method also includes generating a script to update the form by identifying one or more values associated with call-specific data in the wireless network. The nano-material providing additional electron emission through secondary electron emission. The method of harvesting includes extracting bone marrow from a joint, adding a biomaterial, and adding clotting agent to form a clot. Thus, the two linkages are pivoted to drive the support board to move relative to the bottom board to change the distance between the support board and the bottom board so as to adjust the position of the backrest relative to the seat.
