In one embodiment of the invention, a blender blade includes a body portion having an upper surface and a lower surface. The method includes assigning one or more partitions of the geometrical layout design data to one or more computing devices. The first and second cavities may each have a non-uniform thickness and the separator may have a configuration complementary to shapes of the first and second cavities such that the first cavity, the second cavity, and the separator form a combined structure having a uniform thickness during a casting process. Diagnostic methods utilizing compositions of the invention are also provided. The controller outputs the generated operating parameters via a communications interface for use in controlling the central plant equipment. Either monoclonal antibodies or polyclonal antibodies may be used, and in the case of the monoclonals, the specific epitopes of the SAP protein may be detected as well as the SAP protein itself.
