Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...
This study was to investigate effects of growth rate
and cambial age on properties of wood from two increasingly
used hardwood species, red alder (Alnus rubra Bong.) and
Oregon white oak (Quercus garryana Dougl.), for better
understanding factors affecting wood quality in hardwoods.
Thirty 7-year-old trees grown at widely varying...
Many people enjoy going to the beach, but few know how the tides work. People who earn their living on the sea have a special need to understand the tides; the rest of us need to understand the tides for different reasons. Knowing how tides work can help us avoid...
A study was conducted to identify geographical variation in loblolly pine bark and wood properties at the whole-tree level and to quantify the responses in whole-tree
bark and wood properties following contrasting silvicultural practices that included planting density, weed control, and fertilization. Trees were destructively sampled from

Reforesting harvested lands in southwestern Oregon has been
difficult because of low rainfall, high evaporative demand, and
competitive understory vegetation. Herbicides have been a preferred
method to control competing vegetation but herbicide use on federal
lands was curtailed in 1984. As a result, interest in livestock
grazing as a vegetation...

Substations are a crucial element at the transmission and distribution level of electric power systems. The primary substation equipment (power transformers and high voltage switching equipment) is used to transfer and transform electric energy by stepping up or down the voltage in transmission substations.

Novel mucosal vaccines (LL-M2e, LL-HAe, SG-HAe) were constructed from live, non-pathogenic Lactococcus lactis or Streptococcus gordonii that express conserved regions of HA or M2 antigens from avian influenza virus (AIV) A. All three vaccines evoked antigen-specific serum immunoglobulin G (IgG) responses in vaccinated chickens. The addition of the adjuvant cholera...
A three‐dimensional primitive‐equation model for application to the nearshore surf zone has been developed. This model, an extension of the Princeton Ocean Model (POM), predicts the wave‐averaged circulation forced by breaking waves. All of the features of the original POM are retained in the extended model so that applications can...
In rodent models as well as in fish models there are significant

Glutathione, a ubiquitous intracellular tripeptide, protects cells by reacting with electrophiles and radicals that can damage cellular macromolecules. However, glutathione conjugation is now recognized as one mechanism by which drugs and xenobiotics can also be converted to reactive intermediates having toxic consequences to cells. The halogenated alkane 1,2-dichloroethane forms S-(2-chloroethyl)...
Papain-like leader proteases are found in diverse families of human, animal, plant, and fungal positive-strand RNA viruses. In addition to autocatalytic processing, these proteases play a variety of roles in the virus life cycle. In particular, the leader protease (L-Pro) of a prototype member of the Closterovirus genus, Beet yellows...
The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...
This thesis details my investigation of some pharmaceuticals and natural products on the transport of drugs which are substrates of P-glycoprotein (P-gp), such as cyclosporin A (CSA) and digoxin by using Caco-2 and MDCKII-MDR1 drug transport models. Three objectives were performed to address this goal. The first objective was to...

Motivation:
Estimation of bacterial community composition from high-throughput sequenced 16S rRNA gene amplicons is a key task in microbial ecology. Since the sequence data from each sample typically consist of a large number of reads and are adversely impacted by different levels of biological and technical noise, accurate analysis of...

The metabolism of pyrrolizidine alkaloids and other
drugs was studied with regard to nutritional status and
species differences. Pyrrolizidine alkaloids which are biotransformed

California brome and blue wildrye are important native grass species in the Pacific Northwest. However, both species have been reported to have low emergence under less than favorable field conditions. Seed coating is used to improve emergence and stand establishment of various crops. Three studies were carried out to determine...
Myxobacteria represent an interesting class of Gram-negative soil bacteria. These bacteria utilize organic materials from the environment as a food source by the action of their extracellular hydrolytic enzymes. They grow vegetatively in the presence of adequate nutrients. During starvation conditions, however, they aggregate and form multicellular structures called fruiting...
The fermentation of honey-based musts has been a feature of civilization for millennia. Typically comprised of 75-90% (w/w) simple (i.e. fermentable) sugars, the glucose and fructose present are readily fermented by either pitched or adventitious micro-organisms. Nevertheless, despite its venerable heritage, honey-based fermentations are prone to inconsistency, and it is...
Seismic refraction data collected in 1985 by the USGS were used in

This report concerns the disposal of dredging spoil in the Rogue River estuary in 1948. Since there were few shellfish resources existing in the estuary at the time, Oregon Fish Commission biologists had no objection to make to the disposal of the dredged materials.
Response patterns are of importance to survey researchers because of the insight they provide into the thought processes respondents use to answer survey questions. In this paper we propose the use of structural equation modeling to examine response patterns and develop a permutation test to quantify the likelihood of observing...
The release of transgenes into the environment by transgenic plant species is a significant ecological concern, and consequently a containment method for these genetically modified organisms is highly sought after.

Introduction: Biotic soil crust communities contribute valuable ecosystem services and biodiversity in steppe ecosystems. The uncommon crust lichens Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidina, and Texosporium sancti-jacobi are associated with fine-textured soils along rivers of the Columbia Basin. A. schleicheri and R. diploschistidina indicate late-successional habitat and may serve as...
In plantation forests, competition from unwanted vegetation may reduce survival and negatively impact tree growth.
