The objective of this study was to characterize the temporal behavior of contaminant mass discharge, and the relationship between reductions in contaminant mass discharge and reductions in contaminant mass, for a very heterogeneous, highly contaminated source-zone field site. Trichloroethene is the primary contaminant of concern, and several lines of(More)
The objective of this research was to examine the potential for intercalation of trichloroethene (TCE) by clay minerals associated with aquifer sediments. Sediment samples were collected from a field site in Tucson, AZ. Two widely used Montmorillonite specimen clays were employed as controls. X-ray diffraction, conducted with a controlled-environment(More)
The objective of this study was to characterize the behavior of a groundwater contaminant (trichloroethene) plume after implementation of a source-containment operation at a site in Arizona. The plume resides in a quasi three-layer system comprising a sand/gravel unit bounded on the top and bottom by relatively thick silty clayey layers. The system was(More)
This work assesses the anatomical and infectious problems of heteroplastic transplantation from a baboon to a man. The study was carried out with 30 baboons of the primatology laboratory of the CNRS. The aspects studied included the anatomic structure and the biology of the liver, the microbial and parasitic population, and the serological features. Out of(More)
A rapid staphylococcal coagglutination technic for differentiating group A from other streptococcal groups properly classified 500 isolates of beta-hemolytic streptococci when compared with the results of a reference capillary precipitin test. Presumptive classification of the same 500 isolates by bacitracin susceptibility produced a significant number of(More)
