Hydrologic research is a very demanding application of fiber-optic distributed temperature sensing (DTS) in terms of precision, accuracy and calibration. The physics behind the most frequently used DTS instruments are considered as they apply to four calibration methods for single-ended DTS installations. The new methods presented are more accurate than...
The American philosopher and literary critic Kenneth Burke was an "ideologist" (although he never called himself this, and added to that, he spent most of his life avoiding the Marxist term of ideology to describe human "systems" of ideas). Burke instead used the terms "orientation," "rationalization," "perspective." "critical perspective," "way...
Recommendations are provided in this watershed analysis to identify actions and management decisions on the part of BLM that might improve watershed health in the Trask River watershed.
Pesticide chemists have recognized since the 1940's that ultraviolet light was deleterious to the insecticidal properties of certain compounds. However, it has been only within the last 15 years that a number of photodecomposition products of the chlorinated hydrocarbon
insecticides have been isolated and identified. The degradation of insecticides by...
Bacterial soft rot of potato (Solanum tuberosum), caused by Pectobacterium and Dickeya species, is among the most common and destructive potato diseases in the United States. These pathogens cause a variety of vascular wilts, and in potato cause a disease complex that includes tuber soft rot, blackleg, aerial stem rot,...
Batch sorption tests were conducted using 3,4-DCP and cellulose triacetate as the sorbate/sorbent pair. Sorbate concentrations
in the liquid were sampled with time and analyzed by electron
capture detector gas chromatography. Sorption was found to be a two
stage process characterized by a rapid initial uptake followed by a
extended...
Measurements have been made of γ -γ directional correlations on the
following cascades, following the decay of ¹¹¹Pd and ¹⁰⁹Pd :
In ¹¹¹Ag : (454, 633, 762 - 391) keV (526, 797 -633) keV
(526, 797 -[633] -391) keV
In ¹⁰⁹Ag : (390, 413, 424, 551, 558 - 311) keV...
Eight phylloplane yeasts were isolated from backyard apple trees in Corvallis, OR. Yeast isolates were classified to genus or species level. All isolates were tested in vitro for antagonistic activity against the postharvest pathogens Botrytis cinerea and Penicillium expansum. Of these isolates, Aureobasidium pullulans, Sporobolomyces roseus Rhodotorula sp., consistently reduced...
