The practice of modern silviculture on U.S. public lands has been stymied by a legacy of litigation and policy changes since the late 20th century. Forestry in the 1980s was focused on physical science strategies and failed to consider the social complexities of multi-use forest management. Emblematic of the challenges...
In 2020, Oregon suffered one of the worst wildfire seasons on record, with a higher percent of forest area burn, the destruction of residential areas, and the risk to human health. The level of intensity of these wildfires were due to the effects of climate change and Oregon wildfire seasons...
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...
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...
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,...
The presence of per- and polyfluoroalkyl substances (PFAS), organic contaminants first synthesized in the 1940s, has been reported worldwide in a variety of environmental matrices and ultimately in biological systems including humans. Ongoing research into PFAS has included identifying novel PFAS, assessing their fate and transport in the environment, and...
Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic compounds that are used ubiquitously in different industrial fields. However, concerns regarding the potential health impacts of PFAS, including perfluoroalkyl carboxylic acids
(PFCAs) and perfluoroalkyl sulfonates (PFSAs), has raised stakeholder interest regarding continued use of PFAS. Analytical methods for PFAS...
Per- and polyfluoroalkyl substances (PFAS) are anthropogenic surfactants that have recently been identified as persistent organic pollutants. These so called “Forever Chemicals” have been detected in drinking waters, ground waters, soils, and consumer and industrial products globally; with environmental impacts stretching into the artic, far from known PFAS sources. The...
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...
Fusarium proliferatum is a fungus found in soils which produces the mycotoxin group known as fumonisins. Of human concern due to hepato-, nephro- and neurotoxicity, the threat of fumonisins lies within several food items, including corn, wheat sorghum, asparagus and, more recently, garlic. Manifesting as ““garlic rot”,” F. proliferatum infection...
