Emerging data showing the presence of atmospheric microplastics (MPs) has recently raised awareness surrounding the potential of human nanoplastics (NPs) exposure. Due to factors such as weathering, UV exposure, and other biodegradation processes, plastic pollution in the environment breaks down over time into micro (<5 micrometers) and nanoscale (<1000nm) particles....
The purpose of this paper is to evaluate the extent to which ecological
principles were used in four documents of differing scope and intent, that address
management of forest resources and riparian zones in three National Forests of the
Pacific Northwest. We use the phrase "ecological principles" in a very...
Medical imaging technologies play a vital role in early diagnosis of disease by providing internal images of the human body to medical professionals. Computed Tomography (CT) is currently the most commonly used medical imaging technology because it is easy to use, detectors and scanners are constantly improving, and more importantly,...
In this project we study multiple approaches to modeling coupled flow and energy systems, with applications to geothermal fluid flow in geysers. We explore a model from a geophysical point of view, and discuss analysis of a related model. We then focus on our own model which features a free-boundary...
Polybenzimidazoles were synthesized from 3,3'-diaminobenzidine (DAB) and dicarboxylic acids. The polymerizations using the dicarboxylic acid monomers were carried out in polyphosphoric acid (PPA) and phosphorus pentoxide/methansulfonic acid (PPMA) which acted as the solvent and condensing agent. The resulting polybenzimidazoles had inherent viscosities in the range of 0.12 to 0.84 dL/g....
The purpose of this study is to analyze the possibility of political influence
upon the Department of Justice merger decisions within the brewing industry.
Political preference was measured by the congressional ratings of a liberal
political action committee, The Americans for Democratic Action (ADA), thus
giving a liberalness score. Regressions...
Effects of 4-inch (10.16 cm) suction dredge mining on benthic macroinvertebrates in 3rd to 4th order streams were investigated in 1996 by evaluating four mining claim operations in Althouse Creek, Sucker Creek, and Taylor Creek in southwestern Oregon's Rogue River basin. The effects were site-specific. The study showed no significant...
The effects of different dietary lipids on the growth, nutrition
and tissue lipid profiles of rainbow trout raised to market size on a
commercially available ration were examined. Rainbow trout of 80 g
mean initial weight were fed pellets prepared according to Oregon
Moist Pellet specifications for 20 weeks. Salmon...
