Stringhalt is a disorder in horses characterized by high stepping with hyperflexion of the hind limbs. This disorder has been reported from the US, Australia, Chile, and Brazil. In most instances, the disease manifests itself in horses exposed to summer dandelion (Hypochaeris radicata). Stringhalt has been induced by feeding summer...
Numerous evergreen trees and shrubs contain labdane acids, including isocupressic acid, which can cause
late-term abortions in cattle. Recent research has shown that the bark from western juniper trees can
also cause late-term abortions in cattle. Additionally, ranchers have observed that cattle in western juniper-infested
rangelands tend to have decreased...
On May 21, 1998 Kip Kinkel drove to Thurston High School in Springfield, Oregon. Kinkel killed two students and wounded another twenty-two students. He killed his parents the day before. The shootings at Thurston High School came on the heels of a number of prominent school shootings and Kip Kinkel...
The purpose of this study was to investigate the development of an interactive
aquarium design motivated by the employment of an innovative technology used in
scientific research. The study was informed by research on free-choice learning
describing the effects of interactive devices on visitor learning, engagement, and
attitudes. The researcher...
Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete.
Large, in-plane tests on cross-laminated timber...
The aim of this research is to understand and quantify the modeling differences between CSiBridge and OpenSees, and to determine sensitive model parameters. When designing bridges for the high seismic region of California, the California Department of Transportation (Caltrans) performs nonlinear time history analysis of their bridge models. For three-dimensional...
The F₂ progeny from a diallel cross involving seven winter
wheat parents along with the parents were grown at the Hyslop
Agronomy Farm near Corvallis, Oregon to determine the influence
of three plant densities on gene action estimates for yield and its
primary components. The plant densities were designed to...
The purpose of this study was to record on tape and to
analyze the sonagrams of the complete repertoire of the vocalizations of the Rufous-sided Towhee, Pipilo erythrophthalmus
oregonus. Meanings were assigned to a number of the calls.
Sounds of nestlings, juveniles, and vocalizations connected with
parental care were not...
A diallel cross consisting of ten parents was grown on the
Hyslop Agronomy Farm near Corvallis, Oregon, in order to obtain
estimates of the gene action contributing to yield and its components
in wheat. Gene action estimates were obtained by two methods of
diallel analysis and from narrow sense heritability...
