A comprehensive, joint Soviet-American study of the chemistry of Lake Baikal, the world’s deepest (1,632 m) lake, was carried out in July 1988. In this paper, we report the major, minor, and preliminary trace element concentrations for three profiles obtained at or near the deepest and central part of the...
For spatial data visualization, we approach two problems and provide solutions: heat map resolution selection, and heat map confidence interval presentation. Analysts often present spatial data in gridded heat maps, at some chosen resolution. However, many data types vary in density across the domain. We develop variable-resolution heat maps to...
A mathematical model was developed that relates the
ratio, R, of two light flux measurements to the mass concentration,
m, of the atmospheric aerosol particles between
a source of parallel light (e.g., the sun) and the measuring
system. R is defined as the ratio of the light fluxes
passing through...
Molecular chirality plays a critical role in chemistry, biology, and medicine. To study and better understand conformational chirality, it is necessary to obtain structurally interesting molecules that exhibit this form of chirality. Our lab utilizes total synthesis and methodological development to obtain conformationally chiral natural products of interest. We believe...
Until recently, the viscoamylograph had been the primary method for
measuring starch as it relates to noodle quality in wheat. This method
requires a large sample of flour and is time consuming. With the introduction
of the rapid visco-analyser (RVA) in 1986 and the more recent flour swelling
volume procedure,...
The marine ecosystem provides a broad spectrum of services for a wide array of user groups. Such broad use of marine resources often results in use conflicts between ecosystem elements and human interests. To help mitigate these conflicts, the Bayesian Analysis for Spatial Siting (BASS) tool was developed to incorporate...
The focus of this research was to examine the relationship between the Oregon secondary agricultural education teachers’ level of computer-based technology integration, perceptions of barriers to computer-based technology integration, and learning style preferences. Additionally the correlational analysis of the level of computer-based technology integration and the following demographic variables was...
Mitigating for increased human impact to the seafloor associated with resource extraction activities and renewable energy development can benefit from an understanding of the distribution of sensitive marine benthic species. Habitat suitability predictive modeling is a cost effective statistical tool to infer species distribution patterns from constrained sampling locations. However,...

Mitigating for increased human impact to the seafloor associated with
Multibeam sonar data was collected on Nehalem Bank, off of the Oregon Coast with the purpose of increasing the spatial resolution of our knowledge of the area and delineating seafloor habitats. The system used was the Kongsberg Simrad EM-300 operating at 30 kHz. The data set collected includes both topographic...
OBJECTIVE: To investigate whether an increase in daily tooth brushing frequency in children was predicted by either a) having a strong intention to brush twice a day or b) their parents receiving information about their new caries experience.
BASIC RESEARCH DESIGN: Secondary data analyses were conducted on two waves of...
Mohonk Preserve intends to manage their forestland more actively with the mission of promoting forest health, climate-adaptation, and overall ecosystem health for the benefit of their community and recreational users. Climate-adaptive management recommendations (recommendations that address climate change vulnerabilities —by promoting either resistance, resilience, or transition— while helping to meet...
This research looks at the use of PowerPoint as an instructional tool for teaching English language learners (ELL) who studied in a language program at a state university in the Pacific Northwest. The purpose of the research was to discover and to explore the perceptions of PowerPoint supported teaching and...
Programmers often have to choose components online for reuse based on software quality. To help with this choice, most component repositories (SourceForge, CodeProject, etc.) provide information such as user ratings and reviews of components. However, the reusability of components is not immediately obvious from
this material. To make things worse,...
Export-oriented illegal logging has been recognized as a major global problem in environmental, social, and economic terms. It has been argued that export-oriented illegal logging does not benefit the community or government that should be benefited by its own natural resources. The emergence of policy initiatives targeting illegal logging could...

This study is a comparison to establish similarities between the funding resources of college and university athletic bands. The secondary objective is to determine the funding potential that exists as a result of alumni relations. In order to obtain funding information for a variety of athletic band programs, a survey...
The Hemigrapsus oregonensis population at Coquille Point in
the Yaquina Bay Estuary on the Central Oregon Coast was studied
from April, 1972 through May, 1973. The population was found to be
vertically stratified from the 1 ft level to the 5 ft level. Population
densities were found to be most...
Structure-forming invertebrates belong to a polyphyletic group of primarily sessile and sedentary megafauna that can significantly enhance the complexity of physical habitats. A number of these organisms, including cold-water corals and sponges, are known to be slow growing and vulnerable to physical disturbance. In addition, as filter feeders, these invertebrates...
The development of resistance to multiple fungicide classes is currently limiting disease management options for many pathogens, while the discovery of new fungicide classes has become less frequent. To address this pressing issue, a three-part study with different layers of complexity, objectives, and experimental approaches was conducted using the model...
Plate boundaries are commonly regions of complex, diffuse deformation with
the motion across the boundary accommodated by numerous structural systems, rather
than being narrow, discrete zones of deformation. One such boundary occurs where
the North American plate makes contact with Juan de Fuca, Gorda, and Pacific plates
along the west...
There is a growing US interest in UAVs for many applications ranging from agriculture to military. One area of improvement that can be realized in each category is propulsion. Engines with greater efficiency would result in longer mission duration, leading to cost savings and increased usefulness for UAV owners and...
