The effects of Phytophthora ramorum stem inoculation on aspects of tanoak physiology and xylem function in saplings and seedlings

Creator:: Stamm, Elizabeth A.
Abstract:: Phytophthora ramorum, an oomycete plant pathogen, is the causal agent of sudden oak death, a serious disease of Fagaceous trees in California and Oregon over the last decade. Tanoak (Notholithocarpus densiflorus) is one of the most susceptible host species, but the cause of host mortality is poorly understood. Previous research...

Characterization and Biodegradation of Commercial Reference Material Capstone 1157

Creator:: Van Meter, Mariann I.
Abstract:: Capstone 1157 is a commercial reference material used in aqueous film forming foam (AFFF) applications and was manufactured by DuPont. The material’s purpose in this project was to be the sole carbon source to microbes in a biodegradation study in a microcosm environment. The goal of this project was to...

Suspect Screening of Hydrocarbon surfactants in AFFFs and AFFF-Contaminated Groundwater by High Resolution Mass Spectrometry

Creator:: Garcia, Raymmah A.
Abstract:: Aqueous film forming foams (AFFFs) are proprietary mixtures containing hydrocarbon surfactants and per-and polyfluoroalkyl substances (PFASs) that are used to extinguish hydrocarbon-based fuel fires. There is limited information on hydrocarbon surfactants in AFFFs and AFFF-contaminated groundwater even though they are more abundant (5-10% w/w) than PFASs (0.9-1.5% w /w) in...

Expanding the Use of 19F NMR Spectroscopy in Per- and Polyfluoroalkyl Substance Analysis: Determination of Total Fluorine and Isomeric Distribution in Aqueous Film-Forming Foams

Creator:: Schaum, Andre F.
Abstract:: Aqueous film-forming foams (AFFFs) are significant sources of per- and polyfluoroalkyl substances (PFAS) in the environment. Current analytical methods that provide quantitative measures of individual PFAS in AFFFs, such as liquid chromatography – tandem mass spectrometry (LC-MS/MS), are often complicated, time-consuming, and expensive. Methods for total fluorine analysis, though quantitative,...

Fluorinated and deuterated surrogates for quantifying microbial transformation of chlorinated ethenes and ethanes in anaerobic groundwater

Creator:: Ennis, Elliot G.
Abstract:: Chlorinated aliphatic hydrocarbons (CAHs) such as vinyl chloride (VC) and 1,-2 dichioroethane (DCA), are wide-spread groundwater pollutants found at many contaminated field sites around the world. Quantitative tools are needed to determine the in situ rates of VC and DCA transformation to ethene in contaminated groundwater. The objective of this...

The 10.0 Guide to Reducing the Risk of Lower-Extremity Injuries Among Female NCAA Gymnasts

Creator:: Dagen, Lacy M.
Abstract:: An Injury Prevention Program Designed to Reduce the Risk of Lower-Extremity Injuries within Women's NCAA Gymnastics Teams. Grounded in a behavior change perspective using an integrated theory model that combines the Health Belief Model and the Theory of Planned Behavior, the culmination of this project is a lower-extremity injury prevention...

Measuring in situ biotransformation in BTEX-contaminated groundwater

Creator:: Alumbaugh, Robert E.
Abstract:: Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

In situ transformation of toluene and xylene to benzylsuccinic acid analogs in contaminated groundwater

Creator:: Reusser, Dominik E.
Abstract:: The rate of removal of benzene, toluene, ethylbenzene and the xylene isomers (BTEX) from contaminated groundwater is needed to design remediation processes. Benzylsuccinic acid (BSA) and methyl-benzylsuccinic acid (methyl BSA) are unambiguous metabolites of anaerobic BTEX biodegradation. An analytical method for quantitative determination of BSA in groundwater samples was developed....

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,...

Residents’ drivers and barriers to participation in the Backyard Habitat Certification Program : Study of socio-ecological factors in Madison South neighborhood in NE Portland

Creator:: Powel, Jinnet
Abstract:: As urban development fractures and reduces available habitat for birds and other wildlife, conservationists are increasing pursuing strategies to improve the habitat value of privately owned yards in and around cities. The Backyard Habitat Certification Program is a collaborative effort between the Portland Audubon Society and the Columbia Land Trust...
