Abstract: An expert system for synoptic climatology. The expert system comprises a user interface that interacts with a user to obtain geographical information. An inference engine executes expert rules based on the geographical information. A synoptic climatology knowledge base provides the inference engine with the expert rules. A method for representing geographical information related to synoptic climatology for use in the expert system. The method comprises partitioning the world into climatic regions. The climatic regions are partitioned into subregions. The subregions are partitioned into zones of climatic commonalty. The climatic regions, subregions and zones of climatic commonalty are put into a frame hierarchy.

Abstract: An immunoassay method that integrates a sample processing component that enables the testing of a variety of environmental matrixes and the components for performing the method, wherein the immunoassay utilizes a monoclonal anti-PCB antibody to detect the presence or absence of PCB based contamination in a sample when tested in a field or laboratory location.

Abstract: An immunoassay method that integrates a sample processing component that enables the testing of a variety of environmental matrixes and the components for performing the method, wherein the immunoassay utilizes a monoclonal anti-petroleum antibody to detect the presence or absence of petroleum based contamination in a sample when tested in a field or laboratory location.

Abstract: An immunoassay method that integrates a sample processing component that enables the testing of samples for the presence of an immunologically non-remarkable compound, such as benzene, by the use of a monoclonal antibody having specific reactivity for an immunologically remarkable compound, such as nitrobenzene, which has been prepared by reacting the immunologically non-remarkable compound with derivatizing agent, and the components for performing the method, wherein one example of the immunoassay utilizes a monoclonal anti-nitrobenzene antibody to detect the presence or absence of benzene contamination in an aqueous sample when tested in a field or laboratory location.

Abstract: An immunoassay method that integrates a sample processing component that enables the testing of a variety of environmental matrixes and the components for performing the method, wherein the immunoassay utilizes a monoclonal anti-PAH antibody to detect the presence or absence of PAH contamination in a sample when tested in a field or laboratory location.

Abstract: An immunoassay for detecting total aldicarb in an aqueous sample suspected of containing the same is disclosed. In the inventive method, an oxidant is added to the aqueous sample, with the oxidant provided in an amount sufficient to oxidize all aldicarb contained in the solution to aldicarb sulfone. Next, the aqueous sample is combined with a thioether solution capable of neutralizing excess oxidant in the aqueous sample to thereby provide a neutralized test solution. The neutralized test solution is then contacted to an antibody capable of binding aldicarb sulfone, and the aldicarb sulfone bound to the antibody detected.
