The Environmental Conditioning System (ECS) was designed to evaluate the
water sensitivity of asphalt concrete mixtures. The ECS subjects asphalt concrete specimens to a series of conditioning cycles including water flow, elevated and/or lowered temperature, and repeated axial loading. The purpose of this research was to: (1) evaluate the ECS...
Substrate and inhibitor specificities have been used to classify
esterases. The purpose of this work was to determine the substrate
and inhibitor specificities of the esterases in an aquous extract of
lyophilyzed carrots.
Esterase activity was determined manometrically at 37°C. The
optimum pH of the carrot esterases with several substrates...
This investigation was conducted to differentiate the esterases
in a water extract of freeze-dried green beans on the basis of inhibitor
and substrate specificities. An attempt was made to classify
these esterases according to the criteria used for animal esterases.
Activity of the esterases was measured manometrically using
the Gilson...
Phytophthora cinnamomi is a soilborne pathogen that causes root rot disease of highbush blueberry (Vaccinium corymbosum L.). When new installations of susceptible blueberry cultivars are infected with P. cinnamomi, plants often fail to grow significant new tissue, greatly reducing yields over the life of the planting. Chemical fungicides are available...
This study was conducted to investigate the accumulation of dietary polychlorinated biphenyls (PCB's) by a Mt. Shasta strain of rainbow trout (Salmo gairdneri). A commercial mixture of PCB's (Aroclor 1254) was added to the diet at a level of 15 ppm on a dry weight basis. Accumulation of PCB's was...
Esterase activity of an aqueous extract of the green bean was
separated into fourteen bands, while aqueous extracted pea esterases
revealed seven bands, by polyacrylamide-gel electrophoresis. The
fourteen bands of bean esterase activity formed three groups; slow,
intermediate and fast moving. α-Naphthyl acetate, propionate, and
n-butyrate and AS naphthol acetate...

The paleomagnetic history of the volcanic rocks of Easter
Island was investigated using standard paleomagnetic techniques.
The remanent magnetization of 673 specimens from the three volcanic
episodes recognized on the island were measured using a spinner
magnetometer. Inclinations, declinations and virtual geomagnetic
poles were calculated for each flow. The majority...
The Chloroflexi CL500-11 clade contributes a large proportion of the bacterial biomass in the oxygenated hypolimnia of deep lakes worldwide, including the world's largest freshwater system, the Laurentian Great Lakes. Traits that allow CL500-11 to thrive and its biogeochemical role in these environments are currently unknown. Here, we found that...
