Describing the thermal regimes of two northeastern Oregon streams

Creator:: Raven, Sonja E.
Abstract:: Two tributaries of the south fork of the Burnt River, near Unity Oregon were studied during the summers of 2000 and 2001 to determine water heating and cooling patterns. Hourly temperature data were recorded for air, water, and soil parameters at four elevations 150m apart on Barney and Stevens Creeks....

An Investigation of soil, vegetation and mycorrhizal characteristics associated with native grass re-esablishment in crested wheatgrass seedings

Creator:: Raven, Karen A.
Abstract:: Since the 1930's, many fields on the Crooked River National grasslands have been seeded to crested wheatgrass (Agropyron desertorum). While some of these fields remain dominated by crested wheatgrass others had a greater presence of deep rooted native perennial grasses such as bluebunch wheatgrass (Pseudoroegneria spicata). Twenty eight fields previously...

Reduced toxicity of benzethonium chloride to Escherichia coli through adsorption onto titanium dioxide nanoparticles

Creator:: Waldron, Kerri Raven
Abstract:: Antimicrobial agents are being increasingly used in consumer soaps and detergents, despite a lack of data demonstrating their efficacy in such products. This study investigated the nature of the interaction between different crystalline structures of titanium dioxide nanoparticles and BTC, and explore which structure, if any, could be best used...

Providing the best turbulent heat flux estimates from eddy correlation and bulk methods using DYNAMO data

Creator:: Marion, June Raven
Abstract:: In this thesis, data collected during the Dynamics of the Madden Julian Oscillation (DYNAMO) field campaign, conducted in the Indian Ocean in Fall of 2011, is used to compute heat fluxes at the air-sea interface by evaluating eddy covariances and bulk aerodynamic formulae. Errors in daily average gridded fluxes computed...

Active Learning and the ALEKS Placement Test in College Algebra : An Observational Study

Creator:: Dean, Raven
Abstract:: In 2012, a university in the north western United States began offering a redesigned college algebra class that had a greater emphasis on active learning. Specifically, two out of four class periods were completely devoted to students working together in small groups on carefully designed worksheets. Two years later, the...

Hydrogeography of Cloudburst Flooding in the Himalaya

Creator:: Michelsen, Sonja
Abstract:: Even though cloudburst events in high mountain areas can be highly destructive and result in significant losses of life, little is known definitively about these flood events. An exact understanding of the driving processes, typical precipitation rates, and impacts of cloudburst events remain uncertain. This study seeks to advance knowledge...

The expression of embryo maturation genes in wheat and the role of abscisic acid

Creator:: Berge-Chandler, Sonja Kay
Abstract:: A set of genes which show developmental and tissue specificity are expressed late in embryo maturation during grain formation in wheat (Triticum aestivum). Two members of this maturation gene set (MGS) are Em and triticin, a 7S globulin. Results presented here show that during embryogenesis, the expression of Em mRNA...

Selenium metabolism in the chick and effects of Vitamin E and selenium on heat stress

Creator:: Alayan, Mohammad Atta
Abstract:: An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in chick blood. Se⁷⁵-selenite is taken up by RBC (13% within 20 minutes) and expelled into the plasma to become bound to proteins. In contrast, Se⁷⁵-SEM showed a more gradual and continuous buildup...

The Importance of N-3 Fatty Acids in Health and Disease

Creator:: Connor, William F. and Connor, Sonja L.
Abstract:: The n-3 fatty acids have important effects to modulate and prevent human diseases, particularly coronary heart disease. Their effects upon the brain later in life to prevent certain disorders such as Alzheimer's Disease are unknown but are certainly worthy of study. Certainly the evidence is now very strong that the...
