Determination of ethyl glucuronide and ethyl sulfate as human biomarkers of alcohol exposure in urine by liquid chromatography/electrospray tandem mass spectrometry with large volume injection

Creator:: Hu, Yan
Abstract:: This research was undertaken to develop a sensitive, selective, and rapid analytical method to measure ethyl glucuronide (EtG) and ethyl sulfate (EtS) in urine as urinary biomarkers of alcohol exposure. Large-volume injection (LVI) coupled with liquid chromatography / electrospray tandem mass spectrometry was used to eliminate the need for either...

Extreme value index estimation with applications to modeling extreme insurance losses and sea surface temperatures

Creator:: Henry, John B.
Abstract:: The extreme value index (EVI) links the generalized extreme value (GEV) distribution and the generalized Pareto (GP) distribution. These two distributions are fundamental in extreme value theory (EVT), with the GEV distribution being the only possible non-degenerate limiting distribution of properly normalized maxima of iid random variables, and the GP...

Reproductive Effects of PG-600 Administration in Ewes

Creator:: Habeeb, Hayder
Abstract:: Sheep are seasonally polyestrus, which means they do exhibit estrus and ovulation during the short daylight (breeding season) and do not during the long daylight (nonbreeding season). To stimulate the ewes to ovulate during the nonbreeding season, various hormonal treatments have been used. PG-600 contains both equine chorionic gonadotropin and...

Quantities of prostaglandins in whole and extended bovine semen and their potential effect on fertility following insemination

Creator:: Jaeger, John Ralph
Abstract:: Our objectives were to determine 1) the concentration of prostaglandin F2α (PGF2α) in whole and extended bovine semen, 2) if concentrations of prostaglandins in extended bovine semen are correlated to fertility, and 3) if PGF2α administered at the time of artificial insemination would improve conception rate. Concentration of PGF2α tended...

Scaling, ash-driven bistability, and other agents of soilscape genesis discovered while digitally mapping soils of the Blue Mountains, Oregon

Creator:: Almquist, Vance Warner
Abstract:: This dissertation reports on four related, though separate projects. The first project details the process of carrying out a digitally augmented soil mapping (DSM) effort alongside an ongoing survey in Oregon's Ochoco National Forest (ONF) using a Random Forest algorithm. The second chapter describes a initial soil survey in Oregon's...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

Deposition and characterization of thin films

Creator:: He, Shidong
Abstract:: Recent studies have indicated that nickel gallium alloys can be effective for the catalytic hydrogenation of CO2 to methanol. To simplify the characterization of NiGa catalysts, we are developing model systems using NiGa thin films. We prepared NiGa thin films by RF magnetron sputtering using an equiatomic alloy target, followed...

Citizen Science Research : A Focus on Historical Whaling Data and a Current Marine Mammal Citizen Science Project, Whale mAPP

Creator:: Hann, Courtney
Abstract:: Citizen science work has built the foundation of much of our knowledge on regional-scale large cetacean spatial patterns through historical whaling data. Historical whaling data on sperm whales was used as an example to show the type of ecological questions large-scale, long-term citizen science datasets can address. Results from the...

Understanding Signals of the South Pole Ice Core: Chronology, Climate, and Firn Processes

Creator:: Epifanio, Jenna A.
Abstract:: The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...

Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

Creator:: Lee, James E.
Abstract:: Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...
