Polymer catalysts for photovoltaic cells, as well as related compositions and methods, are disclosed. This monoclonal antibody, while being highly specific for anhydroecgonine methyl ester and ecgonidine, does not cross-react at a significant level with the primary cocaine metabolites of powdered or injected cocaine. The second device decodes the command, in response determines a plurality of CPP commands, and outputs the plurality of CPP commands onto the CPP bus. The method also comprises etching at least a region of the imprinted structure and the substrate to remove at least a portion of the imprinted structure and the substrate. With this configuration, tampering of CCI and data forming the CPS unit can be prevented, and authorized content use can be realized. The access has a funnel-like taper in the paper running direction and, downstream of the taper of the access, there are on both sides depressions which are sufficiently large that, in the second or third position, they accommodate both leading ends of the paper guide elements such that the latter lie to one side of the paper run.
