The H. J. Andrews Experimental Forest in the Cascades of
central Oregon provides a unique opportunity to study spatial
climate patterns on a relatively small scale. Historical
records at the 64 square-kilometer site provide a spatiallydense
30-year dataset. Thermal regimes at the H. J. Andrews
are generally known but the...
Nuclear Factor, Erythroid Derived 2, Like 2 (NFE2L2 or Nrf2) is the primary transcription factor in cellular defense against oxidative and xenobiotic stresses in higher eukaryotes. This basic leucine zipper transcription factor regulates over 200 antioxidant, detoxification, and lipid metabolizing genes by binding to the Antioxidant Response Element (ARE; a...
This paper outlines a model of human development to
help guide contemplative practice in parenting and
facilitate prayerful understanding of parent-child
development with a focus upon one's own parent-child
relationship.
The model draws from the tree of life symbolism
represented by the cross and the spiral and further
elaborated through...
On September 12th 1960, just two months prior to one of the closest
Presidential elections in American history, John F. Kennedy faced the Houston
Ministerial Association and delivered a powerful speech on religion and
Americanism. The "religious issue" of the 1960 campaign drew immense interest
and trumped other issues pertinent...
A model to predict ammonia losses from sprinkler applied animal
wastes was developed; in order to accomplish this, a review of literature
was performed to determine possible methods of predicting ammonia
losses during sprinkling. As adaptability to a large variety of situations
was considered of maximum importance, the number of...
Physicists solve problems and communicate their work using many external representations, such as equations, words, diagrams, graphs, sketches, pictures, and more. To learn physics, then, students must learn to use external representations. In this dissertation, I present three manuscripts. Each manuscript discusses how upper-division Paradigms in Physics students use multiple...
The post-emission total kinetic energy release (TKE) in the neutron induced fission of ²³²Th was measured (using white spectrum neutrons from LANSCE) for neutron energies from En = 3 to 91 MeV. In this energy range the average post-neutron total kinetic energy release decreases from 162.3 ± 0.3 at En...
I conducted field and laboratory studies to determine the impact of the cinnabar moth, Tvria jacobaeae L., on the native perennial herb, Senecio triangularis Hook. The cinnabar moth was introduced into Oregon in 1960 to control the noxious weed Senecio jacobaea L. and is now well established on both the...
The primary goal of this research was to identify the impacts that individual agricultural land uses have on fish communities in small streams located in the Willamette Valley of western Oregon. The diverse nature of the land use features of the valley provided a challenging but useful system for the...
An in-field test of the solvent free microwave extraction of peppermint oil was held in mid-August 2009 at Butler Valley Farms in Stayton, Oregon. Results of the trial were limited due to rapid coalescence of the mint oil prior to entry into the separator. This resulted in no mint oil...
