The present invention relates to methods of eliminating, reducing or preventing bacterial biofilms by means of a fusion protein comprising an endolysin, an autolysin or a bacteriocin to which a peptide with membrane or LPS disrupting activity is fused. Electronic appliances such as computers employed in accordance with the present invention help to ensure that information is accessed and used only in authorized ways, and maintain the integrity, availability, andor confidentiality of the information. Specifically, the pulse stream is temporally aligned with the data stream when the average power of the optical data signal is maximized. The method may further include designating a first portion of the funds allocated to a given resident as inaccessible to the resident and designating a second portion of funds allocated to the given resident as accessible to the resident.
