One method of fabricating intermetallic nickel-aluminum MECS devices involves diffusion bonding together pre-patterned elemental foils of nickel and aluminum. This process shows good potential for the mass-production of NiAl devices, but several quality issues remain. Of large concern is the deformation of internal features during the bonding process. This research...
The optical characterization of transparent conductive thin films is demonstrated. The basics of transparency and conductivity, as they relate to transparent conductor research, are explained. A functional model of the reflectance and transmittance of a sample film, including interference fringes, is derived from the Fresnel electric field amplitude coefficients. The...
Previous research suggests a link between litter size in ewes and differential excretion of fecal hormones. An accurate test for fetal number would be useful to sheep producers and a fecal hormone response could be utilized in such a test. Fifteen previously categorized fecal hormones were analyzed within fecal samples...
The end of the Cold War brought about changes within international political relations that resulted in expanded interest in global civil society. Such developments, like globalization and democratization, have encouraged the growth of social and political organizations. Political scientists have found that these inter-governmental and non-governmental organizations have a significant...
This project calculates the value of β for ice particles based on wavelength dependent values of their refractive and absorptive indices. β is the ratio of the force due to radiation to the force due to gravity acting on a particle in the solar system. This parameter can later be...
Hispanics in Hood River County, Oregon account for roughly 25% of the population, with many employed in agriculture. A community health survey was carried out in Hood River County during the winter months of 2001 with the purpose of evaluating the health conditions, needs, and barriers to access of needed...
Regression testing is a common and necessary task carried out by software practitioners to validate the quality of evolving software systems. Unfortunately, regression testing is often an expensive, time-consuming process, particularly when applied to large software systems. Consequently, practitioners may wish to prioritize the test cases in their regression test...
Cucurbits are grown in production agriculture in Oregon as well as in smallholder agriculture in tropical South America. Experimental research was performed at the OSU Research Farm in 2001 with direct-seeded cucurbits, and literature reviews were conducted to develop a characterization of smallholder farming in tropical South America. The two...
While previous experiments on the physiological activity of primary and secondary cyanolichens have been done, an analysis of photomorphs has never been attempted. Photomorphs of Peltigera britannica (Gyelnik) Hotan-Hartw. & Tonsberg were studied to compare the physiological response of a primary cyanolichen to an additional symbiotic partner (green algea) while...
The purpose of this project was to investigate play and our cultural assumptions as to its usefulness or lack there of. The concepts of hard work versus hard play were explored in order to discover when human beings are operating at their best. In terms of innovation and productivity in...
The timber and Christmas tree industries are important components of the Pacific Northwest economy. A goal of both industries is to produce high quality trees with high growth rates. Accomplishing this requires increased genetic quality of the trees grown. Tissue culture provides the most promise for propagating these superior genotypes....
In this project we measure the neutron capture cross section of ²⁰⁸Pb. We began by calibrating our silicon detector with ²⁰⁴Tl. Two experiments were then performed, the first in December of 1999 and the second in March of 2000. Both experiments were performed in the nuclear reactor of the Radiation...
Various vineyard practices influence the quality of a wine. In 1999, three levels of nitrogen (N), two levels of tillage and two levels of irrigation were applied to Pinot noir grape cultivars at Benton Lane Vineyards in the Southern Willamette Valley. N treatments were zero, soil and foliar applications. Every...
