Abstract: Lowering of a toilet seat lid onto a toilet seat when a toilet is not in use is encouraged by the use of a toilet seat lid having a lid body, with an upper surface, and an actual map secured, typically laminated, to the upper surface. The map is visible when the toilet seat lid is lowered onto the toilet seat. The area of interest may be an activity of interest and/or a geographical area of interest of interest for a potential user. The map may also be personalized for a potential user. The map may comprises at least one of the following: an aircraft navigation map, a nautical chart, a ski lift/run map, a road map, a trail map and a topographic map.

Abstract: Antigens characteristic of all species of Listeria except L. denitrificans comprising proteins found in Listeria heat extracts, the major antigen having a molecular weight of from about 30 to about 38KD and comprising three immunogenically different epitopes and others comprising proteins having a molecular weight range of approximately 17KD to the major antigen and comprising an epitope immunoreactive with antibodies that are also reactive with one of the three epitopes on the 30 to about 38KD protein. The invention also comprises mouse monoclonal antibodies specifically reactive with the identified epitopes on these antigens.
