Manned missions beyond low-Earth orbit present tremendous, multifaceted radiological challenges. The deep space radiation environment contains high-energy protons and heavy ions, which are not sufficiently shielded by the aluminum alloys that have historically been used in spacecraft. To address these shielding concerns, polymer-based nanocomposites have been proposed. Radiation transport simulations...
This study examined the Water Footprint Computer Assisted Board Game (WFCABG) as a tool for enhancing the social learning of water resources issues surrounding commodities trade. The study engaged 73 students from various countries and professional backgrounds, in two academic settings in two different countries: Oregon State University (United States)...
Barley (Hordeum vulgare L.) is one of the oldest known domesticated crops. Originally cultivated for human consumption, other end-uses have gained importance over the millennia. Barley is the fourth most important cereal crop in the world (FAO-STAT, 2011), and today it is mainly used as animal feed or malted for...
Studies to evaluate resistance in snap beans, Phaseolus vulgaris L. to adult western spotted cucumber beetles, Diabrotica u. undecimpunctata Mann. were conducted in greenhouse cages, field cages, field plots, and in temperature controlled cabinet in the laboratory. Results showed that there were differences in susceptibility to adult feeding injury between...
In conventional cropping systems in the Willamette Valley, slow
establishing grass species, such as Kentucky bluegrass (Poapratensis L.) are planted in the spring and seed is not harvested
until the following year. Due to increasing annual production
costs, it is necessary to generate a cash return from each field
each...
Burnout is a state of physical or emotional exhaustion and disconnectedness induced by continuous stress that affects various aspects of an individual’s life. Physicians experience burnout at a higher rate than other professions due to the highly stressful nature of their work. Consequently, physicians are at a higher risk of...
In site index studies, the hypothesis that height
growth of most conifers is independent of stand density
is commonly accepted. However, some studies have shown
height growth to be influenced by density particularly
on medium to poor sites.
In this study two locations representing a high
quality site (Hoskins area,...
Thermal oxidation of methyl oleate was studied over a range of temperatures from 50 C to 150 C for periods of time up to 30 min. Degradation was quantitatively followed by gas liquid chromatography (GLC) and liquid scintillation counting of the products of methyl oleate-U-14C heated under a stream of...
