The seasonal variation of wind speed fluctuations is studied at
four locations in The Dalles area of the Columbia River Gorge.
Three of the sites are located in or near the valley floor while the
fourth site is on top of a 900 m (3000 ft) ridge just north of...
This study was designed to identify those specific mathematics
computational and application skills, and combinations of mathematics
skills, which have a positive relationship to success in introductory
chemistry for community college students.
Additional areas of interest investigated, but secondary to the
main study, were the relationships between mathematical growth
shown...
People are increasingly staring at device screens which emit predominantly blue light. Because LED technology is relatively new, we do not know what effects blue light has on our long-term health. Blue light exposure leads to a dramatic decrease in longevity in Drosophila, thus this study aims to explore possible...
Forest harvest practices can impact nutrient concentrations and stream temperatures, altering aquatic ecosystems. To better inform future sustainable forest resource management practices, quantifying the impact of current practices on water quality, particularly in headwater streams is important. In this study, I quantified monthly nitrate-nitrite (N) and orthophosphate (P) concentrations, 7-day...
Silene rectiramea (Grand Canyon campion) is a rare endemic plant species found only in Grand Canyon National Park. There is limited biological and ecological information available about this plant species and the extent of its distribution is unknown. Silene rectiramea is currently not included in a National Park Service monitoring...
The scientific method applies hypothesis testing to material samples through experimentation, measurement, and data analysis, which produce representations—or features—that describe phenomena of interest. Biomolecular features come in numerous forms such as values, matrices, graphs, three-dimensional structures, trajectories, and molecular surfaces. Researchers have tested thousands of features related to protein molecules...
Understanding the effects of habitat disturbance on a species' habitat selection patterns, and demographic rates, is essential to projecting the trajectories of populations affected by disturbance, as well as for determining the appropriate conservation actions needed to maintain those populations. Greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern...
Highway capacity has traditionally been treated as deterministic. In reality, however, capacity can vary from time to time and location to location due to inclement weather, various driving behavior, traffic incident, bottleneck and workzone. This thesis aims to characterize the stochastic variations of highway capacity, and explore its applications.
The...
Over the past ten years, reports of piracy and other forms of maritime violence have been dramatically on the rise. As these reports increase, so too does international attention toward how to solve this. This thesis examines the development of cooperative maritime security efforts in both Southeast Asia and the...
