The largest source of uncertainty among climate models simulating the climate system response to increased atmospheric carbon dioxide concentrations is the cloud feedback, the amplification or dampening of the warming from the carbon dioxide forcing by clouds. Refining our knowledge of the cloud feedback is therefore essential to gaining a...
Toxicological studies show that oral doses of nickel can cause allergic contact dermatitis, and routes of exposure, such as nickel leached from stainless steel cookware are not well characterized. In this study, four variables: grade of stainless steel, cook time, stainless steel seasoning or cooking cycles, and commercial tomato sauces,...

In the years from 1954 to 1956 Agnes Eriksen filled three fashion sketchbooks that contained ⅛ scale patterns, fabric swatches, and styling notations for eighteen garments. I plan to recreate and sew together Agnes Eriksen’s fashion designs into a small snapshot of these three years. The 1950s is a particularly...
Storytelling has been a key societal element for hundreds of years. Over time it has evolved from tales spread by word-of-mouth, to printed words, and most recently to worldwide digital platforms. Stories, and their ability to be both shared and coveted, make them a truly unique aspect of the human...
Isothiocyanates (ITCs) are produced by roots in a variety of agricultural plants, such as those within the Brassicaceae family. ITCs act as fumigants, and are used to control microbial plant pathogens by adding brassica-origin seed meal to soil prior to replanting. However, there is suggestion that the presence of residual...
Continuously tunable diode laser sources coupled to single-mode fiber are useful sources for fiber Bragg grating (FBG) strain sensors. This paper describes the
development and fabrication of such a device. An introduction is given describing
applications of tunable lasers and some of the different methods of creating a tunable
diode...
In Oregon perennial and annual grass seed cropping systems conservation management practices and their impacts on soil health and soil microbial community is not well understood. There is strong motivation to employ conservation tillage and other conservation practices to curb atmospheric carbon levels and improve soil health. However, the few...
The purpose of this project was to optimize the biomass growth of Schizochytrium limacinum SR21. This was achieved by studying the effect of various concentrations of glucose, use of pure glycerol and purified crude glycerol as alternative carbon sources, and inhibition of cell growth with the presence of copper. The...

Although firefighting is associated with a high level of physical health, heart attacks are the leading cause of deaths among firefighters. Research has identified factors that influence health behaviors in the general public, but little is known about this unique subset of the population. Since so little is known, this...
