This paper describes a methodology developed for evaluating
the acceptance of a regional drug information service in providing
patient-specific information. This methodology employs a blinded
study design and uses activity in the patient chart for determining
the acceptance of information.
A total of 60 requests were referred to the regional...
Annual ryegrass (Lolium multiflorum) a major grass seed crop
in the Willamette Valley, Oregon, is presently burned in the fields
after harvest, causing considerable air pollution and general wastage
of a material which could be used in the manufacture of economically
important products. The cellulosic component of straw is relatively...
Experiments were performed to determine whether a direct
correlation exists between the growth rates of tall and dwarf peas
grown either in the light or in the dark and endogenous gibberellin
(GA) content. Three separate but related experimental approaches
were utilized: (1) the determination of possible qualitative and /or
quantitative...
Sulfur-coated urea (SCU), a slow release nitrogen fertilizer,
may be economically competitive with conventional fertilizers, but
little is known of the mechanism of urea release from SCU and the
environmental factors which affect the urea release rate. Objectives
of this thesis were: (1) to determine factors which affect the rate...
Ethylene was produced by Cylindrocladium floridanum and C. scoparium in culture. Production was methionine dependent and maximal during the active growth phase of the fungus, beginning shortly after spore germination. More ethylene was produced sooner by C. floridanum than C. scoparium. Ethylene was produced by Cylindrocladium both from active mycelium...
Great importance has been attributed to the visual aspects of
sexual communication in semi-terrestrial crabs and although P.
crassipes may utilize visual signals, pheromones and chemotactile
signals are important in the release of mating behavior. In the subtidal
C. magister pheromones seem to mediate both courtship and
mating behavior. Visual...
“Active carbon” is a rapidly cycling soil organic carbon (SOC) fraction that acts as an energy and nutrient source for the microbial community. Dilute permanganate oxidation has been used to measure an “active carbon” fraction with the assumption that permanganate oxidation mimics enzymatic decomposition. Permanganate oxidizable carbon (PoxC) has become...
A method was developed to quantify organochlorine pesticides in whale scat. This method would ideally replace analysis of pesticides in blood and tissue samples, which are difficult to acquire. Scat samples were collected from one stranded gray whale and three live whales. The samples were extracted with pressurized liquid extraction,...
Aqueous film-forming foams (AFFFs) are significant sources of per- and polyfluoroalkyl substances (PFAS) in the environment. Current analytical methods that provide quantitative measures of individual PFAS in AFFFs, such as liquid chromatography – tandem mass spectrometry (LC-MS/MS), are often complicated, time-consuming, and expensive. Methods for total fluorine analysis, though quantitative,...
