The WET-Temp (Watershed Evaluation Tool Temperature) model is designed to take advantage of spatially explicit datasets to predict stream temperature distribution. Datasets describing vegetation cover, stream network locations, elevation and stream discharge are utilized by WET-Temp to quantify geometric relationships between the sun, stream channel and riparian areas. These relationships...
Effective treatment of larval bacterial diseases is a difficult problem when
culturing ornamental fish. Oral administration of antibiotics using existing
microparticle types is not effective due to high leakage rates; furthermore, injection of
larvae is not practical. Treatment is currently limited to use of antibiotic baths, . In this
study,...
Plecoptera were collected from four sampling stations selected
to represent a range of conditions on Oak Creek, a small woodland
stream originating in the foothills of the Oregon Coast Range. The
elevation of Site I was 700 ft. while the lowest site was located at 225
ft. Monthly benthos samples...
Hemicellulose hydrolyzate contains many carbohydrate
fractions, the most abundant being xylose, arabinose, and
glucuronic acid. Under mild acid conditions (0.025 -
0.10 M sulfuric acid) and high temperatures (140°C to
200°C) the first two components form furfural through a
series of dehydration reactions. Unlike xylose and
arabinose, glucuronic acid must...
