Efficient use of water in agricultural production involves accurate assessment
and control of the quantity and spatial uniformity of excess percolation. Passive
Capillary Samplers (PCAPS), which sample water from the vadose zone have shown
potential to provide superior estimates of soil water flux compared to alternative
methods. In a four-year...
This research focuses on the anaerobic transformation of trichloroethylene (TCE) that is occurring in the subsurface of the Evanite site in Corvallis, OR. Two anaerobic studies were conducted to investigate the effects of microbial communities in the presence of different electron donors during the anaerobic degradation of trichlorofluoroethylene (TCFE), and...
The chemical stability of folic acid in 25 percent dextrose,
3.5 percent amino acids and multivitamin solution was investigated.
Solutions of 2.5, 5.0, 7.5 and 1.0 mg/liter of folic acid admixed
in the study solution were prepared. Solutions were stored
in light-room temperature, light-refrigeration, dark-room temperature,
or dark-refrigeration. Samples were...
Modern variable speed machine drive (VSMD) systems are used for a variety of purposes including generation, propulsion, pumps and compressors. They employ high switching frequency power electronics to drive the electric machine. The machine is subject to large voltage overshoot if long power cables, are used, called Reflected Wave Phenomena...
Characterization of uranium isotope compositions is of great interest in many nuclear sub-areas for safeguards purposes. Reprocessing facilities utilizing pyroprocessing raised an issue of uranium isotope monitoring due to the difficulty to apply traditional approaches under extreme environments. An rapid and remote method to characterize uranium isotope compositions for such...
Vitamin K₅, 4-amino-2-methyl-1-naphthol hydrochloride, a
water soluble analog of vitamin K has been shown to possess an antimicrobial
activity toward many bacteria, molds, and yeast. Much
of the work reported in the literature is on its use as a food preservative,
and it was the purpose of this study to...
Experiments were conducted to establish whether or not calcium and pectin treatments might improve the typically ragged appearance of canned freestone peaches without impairing other desirable characteristics. and thereby make freestone varieties more acceptable for canning.
Accordingly, Elberta peaches were subjected to three types of prepacking treatments, dipping for 30...
