A diaphragm pump with a bi-component diaphragm pump housing. A flared edge extends at an angle with respect to the cylindrical wall from a portion of the bottom edge. The substituent on the indole nitrogen contains an atom selected from the group consisting of S, O, P, and N. The customized modules are operable to selectively access and process a number of the modules using the API library while the customized modules are processing on the portable electronic device. The invention also relates to fast-dissolving pharmaceutical preparations of active substances having a dissolution rate of at least 70% after 30 minutes, prepared in accordance with the process of the invention. The vaccine is an attenuated or avirulent pathogenic micro-organism that over-expresses at least one homologous antigen encoded by at least one gene derived from the pathogenic micro-organism, and may also express a heterologous antigen.
