Pyrenophora tritici-repentis, causal agent of tan spot of wheat, produces multiple
host-selective toxins (HSTs), including Ptr ToxA, encoded for by ToxA, Ptr ToxB,
encoded for by ToxB, and Ptr ToxC. Variable distribution of these three HSTs among
different isolates of P. tritici-repentis, both singularly and in all possible combinations,
defines...

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds are well-recognized for their immunosuppressive activity, which is mediated through an intracellular receptor and transcription factor, aryl hydrocarbon receptor (AhR). Laboratory animals exposed to TCDD are less resistant to infection and have severely impaired humoral and cell-mediated immune responses. This dissertation addressed the hypothesis that...
Overweight and obesity are a growing national concern, particularly among women and selected minority populations (Ayala, Elder, Campbell, Slymen, Roy, Engelberg, et al., 2004; NHANES, 2003). Pregnant women bear a disproportionate risk of becoming overweight or obese (Greene, Smickikias-Wright, Scholl, & Karp, 1988; Gunderson et al., 2000; Rossner, 1999). Although...
Sources of polar/water-soluble organic compounds conjunctly with apolar biomarkers were characterized in natural organic matter. This multi-biomarker approach was accomplished by a simple analytical method consisting of extraction with dichloromethane:methanol (2:1, v/v), silylation and analysis by gaschromatography- mass spectrometry (GC-MS). Polar and apolar biomarkers, derived mainly from higher plants and...
Data from nuclear ribosomal internal transcribed spacer regions (nrITS) and chloroplast DNA (cpDNA) have failed to resolve phylogenetic relationships in Pinus. To provide greater interspecific resolution, five low-copy nuclear genes were developed from mapped conifer anchor loci. Four genes were sequenced from species representing all Pinus subsections. Individual loci do...

Mismatch repair (MMR) system performs mainly three roles to maintain
genomic stability, correct DNA biosynthetic errors, ensure the fidelity of
genetic recombination, and in mammalian cells participate in the cellular
response to some DNA damages. Deficiencies in mismatch repair increase
mutation rates and cancer risks. In eukaryotes, the MMR system...
Torrubiella is a genus of entomopathogenic fungi in the Clavicipitaceae
(Ascomycota). Species of the genus produce superficial perithecia on a loose mat of
hyphae that forms directly on the host. The genus is estimated to contain about 70
species. Torrubiella is hypothesized to be a close relative of Cordyceps because...
Jointed goatgrass (Aegilops cylindrica Host.) is a serious weed problem in wheat (Triticum aestivum L.) production in the United States. Studies were conducted to determine the outcrossing rate, competitive ability, and effectiveness of certain control practices on jointed goatgrass. A field study was conducted over two years at four locations...
Successful prediction of nearshore sediment migration is important in determining the vulnerability of a coastline. During energetic wave climates (storm events) sediment rapidly erodes from beaches and is deposited offshore. In subsequent milder wave conditions, the sediment migrates shoreward, accreting on the beach and helping to protect the coastline. It...
This thesis examines the motivations of ecological restoration volunteers with the Oregon chapter of The Nature Conservancy. This study helps fill in voids left by a lack of research on the motivations of ecological restoration volunteers.

Results from a post-occupancy evaluation of Kelley conducted in spring 2006 were compared to those from a pre-occupancy survey of occupants in non-green buildings disseminated in spring 2005. The results showed...
Most tsunami studies have been conducted based on the incompressible fluid theory. However water compressibility must be considered for the process of tsunami generation by bottom displacements during submarine earthquakes. During the 2003 Tokachi-Oki earthquake, the ocean-bottom pressure variations were registered by the pressure gauges PG1 and PG2 located right...
Walt Whitman looked to the natural world, which he considered an original example of divine creation, for insights into the methods and patterns of the Creative Force; the poet then intuited connections between these divine natural patterns and human existence and spirituality. Convinced of the divinity of the human body,...
The 3-substituded indolic enamide moiety has been found in many marine compounds over the past 20 years. These indolic enamides exhibit various biological properties such as cytotoxic, anthelmintic, antimicrobial and HW-inhibitory activities. Among these indolic enamides, some are (E)-enamides, like coscinamide A and coscinamide B, others are (Z)-configuration in their...
The behavior of stirrups engaged by diagonal cracks and under service loads is
largely unknown. Full-size laboratory specimens were loaded to induce diagonal
cracks and subjected to high-cycle fatigue loading to represent a service life of 50
years. Tests indicated little change in the average stirrup stress range and mean...

My thesis, entitled "Fantastic Histories: How Malory's Morte Darthur
Influenced Tolkien's The Silmarillion," argues that J.R.R. Tolkien's Silmarillion
shares distinct similarities in style and content with Sir Thomas Malory's Morte
Darthur, primarily in the lack of detail in the descriptions of characters and events, as
each attempts to create a...
The Department of Nuclear Engineering at Oregon State University has recently introduced a neutron radiography facility (OSNRF).

High pressure processing has been suggested as an alternative for milk pasteurization with improved fresh flavor retention. The objective of this...
The effects of trade liberalization and trade integration can be seen in many
developing countries around the world. While freer trade can be said to create benefits
from efficient allocation of resources, it does not ensure that gains from trade will be
allocated equitably in a society. Nor does it...
Over the last 25 years structural adjustment programs have challenged Ecuador's ability to provide adequate social services and employment opportunities. In the wake of these policies, many women have turned to non-governmental agencies for possible solutions and assistance. Empowerment programs as a form of development work in particular have been...
There is growing interest in using nutrient manipulations to control invasive

Many contemporary fisheries and wildlife issues are complex, messy, and divisive. Most share a set of common characteristics including a lack of comprehensive scientific information, a limited understanding of biological processes, a scarcity of agency staff, time, money, and a tendency for differences over policy preferences to end up as...
Greater sage-grouse (Centrocercus urophasianus) populations declined range wide during the past 50 years. Grouse populations were 2-3 times larger than the current population as recently as the early 1970's. In addition to habitat loss and fragmentation, declines were attributed habitat degradation that caused reduced productivity. Because chick survival remains the...

Amphidinolide B₁ is one of the most potent cytotoxic compounds in the
amphidinolide family. Its bioactivity and intriguing structure has drawn
attention from synthetic chemists. Although numerous synthetic efforts toward
the total synthesis of amphidinolide B₁ have been published, it still remains an
unconquered synthetic target.
One of the unique...
During the last decade environmental management has moved from reaction-based management to regulatory requirements to a more progressive approach that incorporates regulatory requirements and voluntary programs, such as the ISO 14001 environmental management system (EMS), to successfully administer their environmental programs. Organizations that transitioned from reaction-based to progressive management through...
Natural and synthetic estrogenic compounds detected in surface waters have
been linked to endocrine signaling disruption in several species. Endogenous
