Soil quality assessment of Willamette Valley soils and root colonization potential by arbuscular mycorrhizal fungi

Creator:: Allen, Natalie M.
Abstract:: Interest in measuring soil quality continues to increase worldwide in view of demands on land productivity and the necessity to preserve soil resources, yet identification of suitable indicators for soil quality assessment is still evolving. This study adapted 10 biological, physical, and chemical indicators of soil quality identified by the...

A Practical, Ethical Critique of Hydraulic Fracturing and the Shale Gas Extraction Process

Creator:: Bullock, Claude George, III
Abstract:: This thesis analyzes the emerging technology of hydraulic fracturing and shale gas extraction process through a pluralistic philosophical approach. Rather than defending traditional values in nature, such as intrinsic value, I defend a metaphilosophical pragmatism centered on policy implications. I argue that different philosophical positions will, most of the time,...

Ethics and Human Biomedical Enhancement : A Case for Compatibilism

Creator:: White, Benjamin A.
Abstract:: This thesis explores some of the ethical issues pertaining to the use of so-called radical enhancement technology. Key concepts analyzed include “normal function”, “human being”, and “personhood.” I argue that the use of these key concepts in the debate thus far has lacked philosophical rigor, and that a reexamination of...

Addressing wastewater epidemiology limitations with the use of dynamic population surrogates, complementary urinalyses and in-situ experiments

Creator:: Brewer, Alex J.
Abstract:: Wastewater epidemiology is an emerging discipline that requires collaborative research involving analytical chemists, drug epidemiologists, and wastewater engineers. Wastewater epidemiology involves the sampling and quantitative analysis of raw wastewaters from communities for illicit drugs and their metabolites. Mass loads (mass per day) and per capita (mg per day per person)...

Large volume (1,800 µL) injection HPLC/MS/MS for the quantitative determination of illicit drugs and human urinary biomarkers in municipal wastewater

Creator:: Chiaia Hernandez, Aurea C.
Abstract:: A sensitive, selective, rapid analytical method based on large-volume injection (LVI) liquid chromatography/ tandem mass spectrometry was developed using commercially-available hardware that eliminates the need for either off-line or on-line solid phase extraction. Centrifugation followed by the direct injection of 1,800 µL was used for the quantification of illicit drugs,...

Vertical Structure of the Lower Troposphere in a Changing Arctic

Creator:: Watkins, Daniel M.
Abstract:: The Arctic climate system is changing dramatically as a response to rising atmospheric greenhouse gas concentrations. Key indicators of Arctic change include thinning and retreating of Arctic pack ice, thawing permafrost, greening tundra, and rising surface temperatures. The structure of the atmospheric boundary layer influences and is influenced by processes...

Numerical model investigations of wind-driven coastal circulation

Creator:: Cervantes, Brandy T.
Abstract:: The effects of wind forcing on coastal ocean circulation are studied using a numerical modeling approach. The first region of interest is on the North Carolina shelf, where the Coastal Ocean Processes (CoOP) Inner Shelf Study (ISS) took place during August - November 1994. ISS observations are used to initialize,...

Moral Disagreement and Moral Genealogy : Two Sources of Empirically-Based Epistemological Challenges to Robust Realism

Creator:: Pho, Alexander
Abstract:: I defend robust realism from arguments that raise epistemological challenges to it based on considerations about either moral disagreement or the genealogy of our moral beliefs. The first argument is the “Argument from Conciliationism,” which contends that the moral disagreements that obtain between moral peers give us reason to believe...

Per- and Polyfluoroalkyl Substances: From Disposition on Consumer Products and Field Materials to Treatment of Contaminated Groundwater

Creator:: Robel, Alix E.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are an emerging chemical class of concern. Recently in the United States, Health Advisory Limits for two PFAS in drinking water were established for perfluorooctane sulfonate and perfluorooctanoate in drinking water (set to 70 ng/L combine concentration) by the EPA. Because of PFAS mobility, persistence,...

New Foraminifera-Based Proxies to Trace Changes to the Organic and Inorganic Carbon System Since the Last Glacial Maximum

Creator:: Fritz-Endres, Theresa
Abstract:: The production of carbon and export to deep ocean sediments is linked to carbon partitioning between the ocean and atmosphere and is a key driver of climate change over the glacial-interglacial transition. Yet conflicting reconstructions create barriers to understanding changes to the carbon system over this important climate transition. Production...
