An examination of the form and variability of manganese oxide in Columbia River suspended material

Creator:: Covert, Paul Allister
Abstract:: Suspended particulate matter (SPM) in the Columbia River is a mixture of particles of several origins having varying physical and biogeochemical properties. The relative abundances of these freshwater particles changes with season and apparently also with tide. Prior investigation has quantified seasonal variation of organic material in both the Columbia...

Nongenomic action of progesterone inhibits oxytocin signaling through the ovine oxytocin receptor

Creator:: Bishop, Cecily V.
Abstract:: Experiments were conducted to characterize the nongenomic effects of progesterone (P4) on binding of oxytocin (OT) to the ovine oxytocin receptor (OTR) and signal transduction. The dose-response relationship of P4 to OT binding to the OTR in endometrium was examined. Progesterone interfered with the binding of OT to the OTR...

Changing student learning approaches in fundamental accounting education through the use of graphic organizers

Creator:: Fisher, Paul A.
Abstract:: The field of accounting has experienced dramatic changes in the past 20 years. Advances in technology and workplace requirements have changed the responsibilities in the accounting position of a historical recorder to a functioning manager within the organization. The curriculum used by accounting instructors has not changed or kept pace...

Investigation of polycyclic aromatic hydrocarbons (PAHs) transport by suspended particulate matter (SPM) in the lower Columbia River and its estuary

Creator:: Gregg, Tiffany
Abstract:: This study aims to improve knowledge of how suspended particulate matter (SPM) affects hydrophobic contaminant transport in the lower Columbia River and its estuary, using polycyclic aromatic hydrocarbons (PAHs) as model compounds. It is hypothesized that PAHs are transported to the estuarine turbidity maximum (ETM), a prime feeding zone in...

Hydrogen isotopic composition of C₃₇ alkenones and the ecology and physiology of coccolithophores

Creator:: Wolhowe, Matthew D.
Abstract:: A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...

The atmospheric chemistry of particulate-bound polycyclic aromatic hydrocarbons : concentration, prediction, laboratory studies, and mutagenicity

Creator:: Jariyasopit, Narumol
Abstract:: The trans-Pacific atmospheric transport of particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) to remote sites in western North America has been well documented and has triggered research questions regarding to atmospheric transformation of PM-bound PAHs and the potential impacts on human health from their inhalation exposure. In this dissertation, field...

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...

Half Array Architecture for Advancing Microchannel Heat Recuperation to Market

Creator:: Brannon, Samuel T.
Abstract:: High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...

The beginnings of a Russian natural history : the life and work of Stepan Petrovich Krasheninnikov (1711 - 1755)

Creator:: Koroloff, Rachel
Abstract:: Stepan Petrovich Krasheninnikov (1711 – 1755) was a successful early Russian naturalist whose professional and social destinies were linked to eighteenth-century Russia's nascent but growing naturalist tradition. During his own time Krasheninnikov bridged the gap that existed in Russia between a distinctly European scientific practice and a tradition of Russian...

Assessing the role of reactive metal species in soil organic matter cycling using chemical imaging

Creator:: Keiluweit, Marco
Abstract:: Intimate associations with reactive metal species permanently protect soil organic matter (SOM) from microbial access and oxidation, contributing to the build-up of organic carbon (C) stocks in soils. It is increasingly recognized, however, that such associations can be reversible and that reactive metal species might even facilitate the oxidation of...
