The reaction of F, often a component of industrial
wastes and phosphatic fertilizers, with soil was studied
with regard to sorption reactions and resultant changes in
solution composition. Sodium fluoride solutions (0.0 to
2.5 mmol/L F) were equilibrated with ten soils for 24h.
The soil extract solutions were analyzed for...
The behavior of metribuzin [4-amino-6-(1,1-
dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one] and
ethyl-metribuzin (4-amino-6-(1,1-dimethylethyl)-3-
(ethylthio)-1,2,4-triazin-5(4H)-one] in soil was studied to
determine if differences in herbicide behavior in soil could
explain (a) the inconsistent herbicidal activity of these
chemicals and (b) the greater activity of metribuzin, as
compared to ethyl-metribuzin.
Metribuzin had higher activity than ethyl-metribuzin...
An instrument which measures current from D.C. to 50 megahertz
by clipping a transformer core around a current carrying conductor
is discussed. A Hall device, which is installed in the core cross-section, detects the flux in the core. This Hall device in conjunction
with an amplifier is used to null...
Final report for project completed with funding from the Oregon State University Agricultural Research Foundation Continuing Researchers Support Program.
Riparian zones provide habitat for breeding birds in the semiarid western United States; however, there are few data available that address the effects of livestock grazing strategies on riparian habitats and avian communities. Documenting avian community composition in different riparian vegetation communities and relating vegetation communities to livestock grazing strategies...
Despite the belief that fuels management, a form of prescribed fire that reduces accumulated fuels in commercially thinned forests, is necessary to restore forest 'health' in the Pacific Northwest, its effects on wildlife has received little attention in the scientific literature. Because fuels management is supported, funded, and implemented nationwide...
The intracellular life cycle of Chlamydia has been difficult to study due to the inability to genetically manipulate the bacteria. As a result, indirect methods have been employed to study the pathogen and the aspects that contribute to its unique intracellular life cycle. A wide variety of laboratory adapted strains,...
Celebrity culture is part of a long history of fame, but the modern celebrity individual came into focus in the nineteenth century. The first part of this thesis distinguishes modern celebrity – including its morality – from other types of fame, explores the intersection of celebrity and gender through the...
Chlamydia possesses an immense importance within both human and animal medicine when looking at pathogens. Chlamydia trachomatis infections have been shown to affect both the eye and genital tracts in millions of humans and animals every year [13]. As C. trachomatis strains are highly conserved in patients, it has made...
