Stevia (Stevia rebaudiana) is a perennial herbaceous plant native to Paraguay and used traditionally by the native Guarani peoples for centuries to sweeten medicinal teas. Stevia has only been commercially cultivated over the past 50 years and cultural practice information suitable for implementation by growers is limited. Currently stevia’s commercial...
Veratrum californicum (common name: corn lily) is a wild plant species that grows in the Intermountain West, its range extending from British Columbia to Mexico. Corn lily is of interest because it has the potential to provide pharmaceutical precursors for use in the treatment of cancer. Pharmaceutical companies are currently...
This study sought to better understand the voluntary adoption of water quality improving practices by agricultural producers in Northern Malheur County, Oregon. The Reasoned Action Approach/Theory of Planned Behavior was used as a theoretical framework to identify barriers and incentives to adoption. Study findings suggest that producers primarily consider practical...
Reflection of an obliquely incident solitary wave at a vertical wall is studied experimentally in the laboratory wave tank. Precision measurements of water-surface variations are achieved with the aid of laser-induced fluorescent (LIF) technique and detailed temporal and spatial features of the
Mach reflection are captured. During the development stage...

This thesis covers the use of a quarter car model to select damping rates for aFormula Student (FS) car, focusing on minimizing vertical tire force variation to improvegrip. A 2 degree of freedom (DOF) quarter car model is cycled over the road frequenciesof interest and the results compared with the...
Slow magnetosonic shock fronts are unstable to changes made to their shape, a phenomenon known as corrugation instability. The computational models studied considers a system where plasma travels across a shock front. Using the code Linogen, the corrugation instability of a shock front can be theoretically modeled. The results show...
During the 1970’s the United States experienced several periods of high inflation that have been at least partially attributed to positive oil price shocks. The effectiveness of the Organization of Petroleum Exporting Countries at controlling the price of oil has varied over time, as well as the responsiveness of U.S....
Discusses the advantages of drip irrigation and how it can help growers use water efficiently. Covers basic concepts related to components and design as well as management considerations such as placement of the tape, timing and rates, maintenance, and adjustments to fertilizer rates.
