The Independent Multidisciplinary Science Team (IMST) convened 19 regional leaders in salmon management and research in a workshop on Goals for Recovery of Oregon Coastal Native (OCN) Stocks on August 4-5, 1999. The main purposes of the workshop were to 1) define the concept of recovery and 2) to identify...
Winter wheat is commonly grown in dryland cropping systems in the Pacific Northwest region of semi-arid eastern Oregon. For agronomic, economic, and environmental reasons, it is important to understand the long-term sustainability of such dryland systems. The objective of this study was to evaluate the long-term effects of tillage, nitrogen...

With the loss of field burning the amount of crop residue that remains in perennial ryegrass fields has increased. As the amount of crop residue remaining in the field increases so does annual bluegrass. This has resulted in the increased use of herbicides to control annual bluegrass. However, this increased...
While replacement of dietary saturated fat with unsaturated fat has been advocated
to reduce cardiovascular disease risk, diets high in polyunsaturated fatty acids
(PUFA) could increase low density lipoprotein (LDL) susceptibility to oxidation,
potentially contributing to the pathology of atherosclerosis. To assess in vivo lipid
peroxidation and susceptibility, of LDL...
Animation has long been a staple of children's television programming As
public service announcements (PSA5) have become an important part of children's
television programming, cartoon characters have started to appear in this form of
nonprogram material. By standard definition, PSAs are usually a 15 to 60-second spot
that promote education...
Determination of the source and fate of natural (higher plant lipids, marine
lipids, etc.) and anthropogenically (e.g., petroleum, coal emissions) derived
hydrocarbons and oxygenated compounds in the environment was accomplished
using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS)
to characterize or identify molecular biomarkers to be utilized as tracers....
The influence of large-scale processes on natural communities has become one of the central issues of modern ecology. I combined field and laboratory studies to investigate the effects of variation in coastal upwelling on rocky intertidal communities along the central Oregon coast. I examined whether the growth of intertidal barnacles...
In the first experiment, estradiol production was measured in cultured embryos collected on Days 7, 9, 11, 13 and 15 post-mating. Estradiol was detected in Day 7 embryos and production increased approximately 50-fold (P<0.05) in medium recovered from Day 13 compared to Day 11 embryos and was greatest (P<0.05) from...
As the drive continues to reduce the size of Printed Wiring Assemblies (PWAs),
improve performance of electronic assemblies, and reduce costs of these products,
reliable secondary (bottom) side reflow operations must be developed. Attaching Surface
Mount Technology (SMT) components to the secondary side of a Printed Circuit Board
(PCB) is...
