Abstract: A uranium-containing/metal binding complex and process for the determinat of natural and depleted uranium in biological samples such as water, urine, blood serum, saliva, amniotic fluid, cerebrospinal fluid, sweat, stool extract, synovial fluid, tears, semen extract, sputum, and peritoneal fluid. The samples are mixed with a buffer, one or more masking agents, and a solubilizing compound, to form a uranium-containing metal binding complex composition, followed by the addition of a pyridylazo indicator dye to said composition. The increase in absorbance due to the uranium-dye complex is determined with a spectrophotometer or colorimeter.

Abstract: A computer information processing system utilizes parallel processors for organizing and clustering a large number of documents into a large number of clusters for information analysis and retrieval. After the documents are translated into electronic digital documents, each document is converted into a vector based on weighted list of the occurence of different words and terms that appear in the document. The document vectors are grouped together into cluster vectors on different parallel processors according to similarities. New document vectors are simultaneously compared with existing cluster vectors in the different parallel processors.

Abstract: Polycyclic spiroorthoester which undergo expansion on polymerization to f resins, rather than shrinkage on polymerization, are employed in fabrication of composite, filament-reinforced, interceptor motor cases. The advantages which accrue to such use of the specified resins relate to the imparting of unique characteristics to the interceptor motor case such as increased structural strength, a reduction in the number of microcracks and voids, and improved bonding between resin and reinforcement. These unique characteristics impart benefits where needed since composite motor cases are fabricated from high strength filaments or tapes such as fiberglass, graphite, poly-p-phenyleneterephthalamide (Kevlar), in a polymeric matrix, and the primary mode of failure is due either to poor adhesion between the matrix and the filament or tapes or because of the development of microcracks or voids in the matrix.The spiroorthoester, 1,4,6-trioxaspiro [4.
