The opportunities for expanding water supplies in Oregon coastal municipalities are becoming increasingly limited. New water quantity and quality regulations, particularly those designed to protect and rebuild salmon runs, constrain water supply options. At the same time, however, demand for water is increasing. Coastal communities continue to grow in population...
The goal of the Oregon Plan is to restore wild coho and wild steelhead runs. Under the federal Endangered Species Act, wild coho salmon along the Oregon Coast are listed as Threatened and wild Oregon Coast steelhead are a candidate for listing. Although cormorants have been hazed at the Nehalem...
The main result of this written dissertation is a mathematical solution to the problem of multiplex recording for high performance tandem time-of-flight mass spectrometry. The prescription is to use a time-lag accelerator in the second stage to match the ion optical properties of the decay fragments to the requirements of...
This thesis presents a design-oriented model for lightly doped CMOS substrates. The model predicts the substrate noise coupling between noisy digital and sensitive analog blocks in the early stages of the design. The model scales with the size and separation of these blocks and it is validated with device simulations...
Due to its frequent use in agriculture and its frequent detection in surface water,
atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...
Equations for predicting height to crown base are presented for tree species from southwest Oregon. Equations for undamaged and damaged trees were estimated with weighted nonlinear regression techniques. The effects of specific damaging agents on the height to crown base were explored, and damage correction factors were estimated. The damage...
For the past ten years, Douglas-fir on the Oregon and Washington coast has shown a progressive decrease in height and diameter increment as a result of Swiss needle cast, which is caused by Phaeocryptopus gaeumannii. In this contribution, we discuss the effects of silvicultural operations on Swiss needle cast and...
This publication is aimed at watershed councils, government agencies, and specialists (foresters, wildlife and fisheries biologists) interested in riparian area silviculture or watershed restoration. It contains information on the ecology of riparian forests and a checklist of recommended practices and common mistakes made in restoring conifers to hardwood-dominated riparian forests....
The investigation described in this project will test the hypothesis that fluxes of carbon, barium, manganese, iron and uranium associated with fluid seepage at the San Clemente fracture zone significantly affect the geochemical budgets for these elements, and ultimately result in anomalously high benthic fluxes throughout the San Clemente basin.
This report documents oceanographic and meteorological measurements made from instruments deployed on four moorings over the continental shelf west of Oregon, from spring through
summer, 1999. These moorings were a component of an observational and numerical modeling program to study the response of the coastal ocean to wind forcing.
The...
Deforestation, intensive agriculture and chemical use all can cause long-lastingn negative impacts on soil health. With all the vital functions that soils perform and the potential for further soil degradation, it is important that standards of soil quality or soil health be implemented. Soil aggregation is considered to be a...
Northwest cherry cultivars including Prunus avium 'Bing', Prunus avium 'Rainier', Prunus avium 'Royal Anne' and Prunus cerasus 'Montmorency' were separated into epidermal tissue, flesh and pit and cryogenically milled with liquid nitrogen. These samples as well as whole samples from each variety were extracted with acetone followed by a chloroform...
Critics of higher education urge educators to transform their institutions so as to align them with the needs of the twenty-first-century learner. However, colleges desiring to survive in a rapidly changing external environment often discover they must first find a way to make
fundamental changes in their institutional culture. Some...
An organisms' genotype may not be reflected in its phenotype. For example, epistasis - the interaction of non-allelic genes can cause deviations from expected phenotypic ratios. The epistatic interaction between the hooded (Kap) and short-awned (lks2) loci in barley (Hordeum vulgare) precludes the localization of the Kap locus, based on...
Chlamydiae are obligate intracellular bacterial pathogens with a unique biphasic life cycle that consists of an infectious but non-dividing form, called elementary bodies (EB), and a noninfectious but metabolically active form, called reticulate bodies (RB). Chlamydia has an unusual process of cell division of which still remains uncharacterized subject matter;...
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...
Crystallizing a virus can be difficult and not always successful. Forty-eight salts, buffers, and precipitating agents were used in the hanging drop preparations in attempts to crystallize the San Miguel sea lion virus type 5 (SMSV-5). The first attempt resulted in 22 of the 48 solutions forming a precipitate. The...
Indole-3-carbinol (13C), a metabolite of glucobrassicin, is found in cruciferous vegetables. It is able to act as an inhibitor or promoter of carcinogenesis depending on the species, the carcinogen and when it is given in relation to the carcinogen. This is probably due to the fact that it reacts in...
Kincaid's lupine (Lupinus sulphureus ssp. kincaidii [Smith] Phillips) is a federally listed Threatened plant of Willamette Valley prairies. Both low reproduction, due to seed coat dormancy, and competition from invasive plants may threaten the longterm viability of this species. In separate studies, I investigated seed germination and an invasive species...
The diageotropica (dgt) mutation has been proposed to affect either auxin
perception or responsiveness in tomato plants. Auxins and cytokinins are plant
growth regulators known to interact with each other via a variety of mechanisms.
Here, we report the interactions of auxins and cytokinins in VFN8 wild-type and
dgt mutant...
Cell lines deficient in certain genes of the DNA mismatch repair (MMR) system show a marked resistance to the cell killing or apoptotic effects of DNA alkylating agents. The molecular mechanism for this resistance is not yet understood, but is currently of great interest because of the recent use of...
Llama reproductive physiology is unique when compared with other livestock species. Llamas carry 95-98% of all pregnancies in the left uterine horn. It is believed that there is a physiological difference between the uterine horns that contributes to this phenomenon. This study examined the uterine environment for protease and protease...
The purpose of this research is two-fold: to evaluate the success of the new emergency procedures promulgated in 1998 and to characterize the erosion event that precipitated the emergency during January, February and March 1999. These two purposes support each other and provide a holistic understanding of how emergencies arise...
Food Insecurity exists whenever the availability of nutritionally adequate and safe foods or the ability to acquire acceptable foods in socially acceptable ways is limited or uncertain (LSRO, 1990). Factors that increase a household's risk for food
insecurity include being low income and not being able to access formal and...
