"Infestations of the spotted wing Drosophila fly (Diptera: Drosophilidae), an exotic pest, have been found in Oregon fruits in 13 counties. Of the 3,000 species of Drosophila, commonly known as vinegar flies, approximately 175 are known in North America. Two of these known species have been found to be harmful...
Traditional season-long livestock grazing strategy on western riparian areas
has been identified as one of the factors affecting rangeland productivity as well
as wildlife habitat in riparian zones. As alternatives to summer season-long
grazing, summer short-duration grazing (without haying), and fall short-duration
grazing (following haying), were considered in this study...
This publication reviews the growth stages of grapes. For each growth stage (or group of growth stages), the document lists the more effective pesticides used to control insects, weeds, and disease, their rates, and application timing for Oregon grape growers. It also covers the effectiveness of various fungicides for control...

The role of the high density lipoprotein (HDL) molecule is currently an area of great interest within the scientific community. Previously, mouse and human studies have demonstrated an inverse association between HDL cholesterol (HDL-C) levels and cardiovascular disease. Recent clinical trials, which increased HDL-C, have failed to reduce the number...
In the Pacific Northwest, several species of rockfishes (Sebastes spp.) are under extreme conservation measures due to low population levels. Although currently at healthy population levels, one species of interest is the black rockfish (S. melanops), which has been shown to utilize estuarine habitat during its early life history stages....
This pest management guide is developed for use by vineyard managers in Oregon. It provides recommendations for chemicals, formulations, and usage rates of products that are intended to prevent, manage, and control vineyard diseases, insects, mites, weeds, and vertebrate pests. When selecting a pesticide, consider its efficacy and its impact...
BACKGROUND: On the basis of the 2014 guidelines for hypertension therapy in the United States,
many eligible adults remain untreated. We projected the cost-effectiveness of treating
hypertension in U.S. adults according to the 2014 guidelines.
METHODS: We used the Cardiovascular Disease Policy Model to simulate drug-treatment and
monitoring costs, costs...
Spotted wing Drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a pest of small and stone fruits that is widely distributed across much of the United States, Canada, Europe and Asia. Unlike other members of the Drosophilidae that only lay eggs in overripe or rotting fruit, SWD infest ripening and ripe...
This study was conducted to determine the level of knowledge required
by graduating manufacturing engineering students in various
manufacturing engineering competency areas as perceived by managers
of manufacturing from 17 major manufacturing industrial classifications
in the state of Oregon.
Methods and Procedures
A preliminary listing of competency areas was developed...

Behavioral modeling is increasingly an imperative component of system design as the systems under construction become more and more complex. Without behavioral modeling available to the modern designer, design and verification of these systems would be much more laborious. Additionally, with the increasing computational power of today's modeling and simulation...
There is continuing interest in the trend of costs associated with pollution abatement activities. We specify an environmental production technology to model the joint production of good and bad outputs. The joint production model calculates pollution abatement costs and identifies changes in these costs associated with: (1) technical change, (2)...
Air passing upward through the tropical tropopause is “marked” by an annually varying water vapor mixing ratio much as a tape recorder marks a magnetic tape; as the air ascends in the tropical stratosphere, these marks are effaced by a combination of vertical diffusion within the tropics and dilution of...
The purpose of this study was to examine the perceptions of
job stressors in student services professionals. The research
procedures examined the functional aspects of a position with
four dimensions of job stressors: role-based stress, conflictresolution
stress, task-based stress, and stress due to the inefficiency
of others. The independent variables...
Bumble bees provide vital pollination services in both native and agricultural landscapes. However, in recent years, bumble bee populations have experienced global population declines. The primary causes of these declines have been attributed to the environmental impacts of pathogens, pesticide use and habitat fragmentation. While research has examined the impacts...
