Biological agents and their products commonly cause foodborne illnesses. In the United States it is estimated that there are over 76 million cases of foodborne illnesses each year, resulting in an economic loss of approximately $40 billion. These high figures demonstrate the need for bioassays that display a rapid and...
The serotonergic system plays a significant regulatory role in osteoblast differentiation and proliferation. Serotonin (five-hydroxytryptamine or 5HT) may promote or inhibit osteoblast proliferation depending upon the serotonin receptor isoforms expressed by the cell. Classically, 5HT receptor 1B (5HTR1B) reduces osteoblast proliferation by inhibiting phosphorylation of the cAMP response element binding...
Great importance has been attributed to the visual aspects of
sexual communication in semi-terrestrial crabs and although P.
crassipes may utilize visual signals, pheromones and chemotactile
signals are important in the release of mating behavior. In the subtidal
C. magister pheromones seem to mediate both courtship and
mating behavior. Visual...
The metabolism of Strongylocentrotus purpuratus (Stimpson)
was investigated at several levels of urchin organization. Some experiments
were performed with tissues from recently collected
(acclimatized) urchins, Other experiments were performed with tissues
from urchins held at one of two temperatures (acclimated) for
30 days.
Body-component oxygen consumption was measured for bodywall,...

This work explores the electric field induced strain mechanisms in environmentally benign Bi0.5Na0.5TiO3 (BNT) based piezoelectric thin films. Although BNT-based materials show promise as replacements for toxic Pb-based piezoelectrics, the displacement mechanisms are not consistent between thin films and bulk materials, and the differences have yet to be well understood....
In the days following Oct. 5, 2007, the staff of The Daily Barometer - the student newspaper at Oregon State University - was left scrambling for understanding. The paper published a image of a man wearing black face paint for an event called "Blackout Reser." That black face paint looked...
Quantitative measurement of the urban-rural continuum for examination of U.S. rural health disparities is a relatively new research area, where only a handful of studies have investigated health disparities using quantitative rural measures and even fewer have attempted to integrate health variables within said measures. Most U.S. rural health disparity...
This thesis presents an analysis of seventeen contemporary blockbuster films in which women kill people. The purpose of the analysis is to discover the "frames" with which film producers, directors, scriptwriters and actors portray women in film. The thesis first establishes the model in use in the analysis: Entman's model...
