A novel mode of shallow aquifer management could increase the volumetric potential and distribution of underground, freshwater storage: Shallow aquifer storage and recovery (SASR). In this mode, water is efficiently stored in basin fill aquifers with strong hydraulic connection to surface water. Regional numerical modeling can provide a linkage between...
Asthma prevalence in children under age 18 has risen steadily in the U.S. since the mid-1970s. Most researchers attribute this increase to air pollutants, socioeconomic status or urban residence. This study examined asthma prevalence in Lane County, Oregon, using children's asthma hospital discharges (1990-1995), and data from 10 of 16...
An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in
chick blood. Se⁷⁵-selenite is taken up by RBC (13% within 20
minutes) and expelled into the plasma to become bound to proteins. In
contrast, Se⁷⁵-SEM showed a more gradual and continuous buildup...
The purpose of this study was to apply the Combined Index (Con, a hazard screening tool, developed by Dr. Debra Forman of EPA Region III Office of Air Radiation and Toxics Division, to the 1994 and 1995 Oregon Toxic Chemical Release Inventory (TRI) for pollution prevention and facility targeting analysis....
In 1990, the Clean Air Act (CAA) Amendments authorized the regulation of 188 hazardous air pollutants (HAP). Exposure to HAPs at sufficient concentrations and durations can increase both cancer and serious adverse non-carcinogenic effects. The purpose of this study was to conduct a human health risk assessment using data of...
While real-time hybrid simulation has been utilized for structures subjected to seismic events for decades, its use in fluid-structure interaction problems is still a novel endeavor. Gathering data for cascading seismic and tsunami events is difficult due to space constraints in existing experimental facilities, complications regarding the application of scaling...
Extraction of natural gas from shale formations using the process of hydraulic fracturing (fracking) requires the use of thousands of cubic meters of fluid. Hydraulic fracturing fluids are pumped under pressure into shale formations, fracturing the shale and releasing pockets of trapped gases. When the pressure in a natural gas...
This thesis presents a domain specific visual language designed to allow coaches to create content that exhibits the complex 2D interactions observed in the game of American football. Coaches can visually program the content by using symbols and drawing primitives similar to those that they currently use to design static...
With congressional passage of the BEACH Act in October of 2000, Coastal and Great Lakes states were mandated to assess coastal recreation waters for the application of ambient water quality standards. This research encompasses two components involved in applying the BEACH Act statues to Oregon. The first component was to...
Biohazardous waste refers to wastes that are potentially infectious to humans, as well as wastes from animal or plant research that could be potentially infectious to these organisms, or could alter their genetic selection process. Research resulting in generation of biohazardous waste is typically conducted at large, research-based universities. The...
