Pattern recognition at Lawrence Livermore Laboratory
Possible uses of pattern recognition techniques for solving complex scientific problems are discussed, and previous experience in using the pattern recognition computer code RECOG to solve materials problems, specifically in determining the mechanical properties of high explosives, is described.

Oceanic distribution and geochemistry of several trace elements at GEOSECS stations
The biogeochemical and physical processes operating in the oceans create substantial geographical and vertical variations in the oceanic distribution of many trace elements. These variations are brought about by diverse mechanisms and involve trace elements of a wide spectrum of physicochemical and biological behavior. Thus, a knowledge of these trace element distributions can help characterize some of the ocean processes in which they participate. (auth)

Triple-coincidence with automatic chance coincidence correction
The chance coincidences in a triple-coincidence circuit are of two types- -partially correlated and entirely uncorrelated. Their relative importance depends on source strength and source and detector geometry so that the total chance correction cannot, in general, be calculated. The system described makes use of several delays and straightforward integrated circuit logic to provide independent evaluation of the two components of the chance coincidence rate. (auth)

Non-dispersive soft x-ray fluorescence analyses
In a nondispersive x-ray fluorescence analysis system, all x-rays incident on the detector are analyzed according to energy in a time sharing manner. The spectrometer and techniques described were designed to take advantage of the features of a nondispersive detector. These include sensitivity, relatively short geometry, and the ability to detect oxygen and sodium x-rays at the low energy end of the elemental scale. Results are given for analyses of Sirof pottery samples and standard USGS rocks. (LK)

Distribution of transuranic elements in a freshwater pond ecosystem
Preliminary results are reported from a study initiated on the Hanford Reservation concerning the ecological behavior of $sup 238$Pu, $sup 239$Pu, $sup 240$Pu, and $sup 241$Am in a freshwater environment. This study involves a waste pond which has been receiving Pu processing wastes for about 30 years. The pond has a sufficiently established ecosystem to provide an excellent location for limnological characterization. In addition, the ecological distribution of Pu and Am was investigated. The pond is also highly enriched with nutrients, thus supporting a high level of algal and macrophyte production. Seston (30 percent diatoms) appears to be the principal concentrators of Pu transuranics in the pond system. The major sink for Pu and Am in this system is the sediments. Organic floc, overlaying the pond sediments, is also a major concentrator of transuranics in this system. Aside from the seston and floc, no other ecological components of the pond appear to have concentrations significantly greater than those of the sediment. Dragonfly, larvae, watercress, and snails show concentrations which approximate those of the sediments but nearly all other food web components have levels of Pu and Am which are lower than those of the sediments, thus, Pu and Am seem …
