Cyclopropenoid fatty acids (CPFA) are natural components of
cottonseed oil, a major food oil in the United States. The ability of
CPFA to cause abnormal biochemical and physiological effects when
fed to laboratory and farm animals has prompted an investigation of
their effects on mice.
Between 0.05 and 0.55% CPFA...
Of 149 wild animals from two western Oregon river drainage
areas and other localities in which "salmon poisoning" disease (SPD)
is enzootic, including ten mammalian and two avian species, 79
harbored Nanophyetus salmincola, the SPD vector. The shorttail
weasel, Mustela erminea; river otter, Lutra canadensis; spotted
skunk, Spilogale putorius; Norway...
Bench scale column studies were used to examine the partitioning of microorganisms between groundwater
and a geologic medium and to examine the effect of hydrogeology (i.e., porous- versus fracture-flow) on
organism partitioning. Replicated columns were constructed with intact basalt core segments that contained
natural fractures and with the same basalt...
The bacteria colonizing geologic core sections (attached) were contrasted with those found suspended in the groundwater (unattached) by examining the microbiology of 16 depth-paired core and groundwater samples using a suite of culture-independent and culture-dependent analyses. One hundred twenty-two meters was continuously cored from a buried chalcopyrite ore hosted in...
We present the results of a study of optical scattering and backscattering of particulates for three coastal sites that represent a wide range of optical properties that are found in U.S. near-shore waters. The 6000 scattering and backscattering spectra collected for this study can be well approximated by a power-law...
