Direct numerical simulations (DNS) of a shear layer with salt-fingering-favorable stratification have been performed for different Richardson numbers Ri and density ratios R[subscript]p. In the absence of shear (Ri = oo), the primary instability is square planform salt fingering, alternating cells of rising and sinking fluid. In the presence of...
This study investigated the effect of exposure to elevated temperature on the yield strength of single-shear nail connections when subjected to lateral loading. Solid sawn lumber and laminated veneer lumber were used as framing members and two different thicknesses of both oriented strand board and plywood were used as the...
OBJECTIVE – To determine the effect of 3 differing transfusion techniques on survival of autologous canine red blood cells (RBCs).
DESIGN – Prospective, blinded study.
SETTING – University Teaching Hospital.
ANIMALS – Nine healthy dogs.
INTERVENTIONS – Three distinct preparations of RBCs, each representing ~1% of red cell mass, were...
This current report provides only a snapshot of the high school experiences and expectations for entering students’ first college year. As expected the results are consistent with the 2009 BCSSE results.
Overall, OSU’s entering students are optimistic about their ability to succeed at OSU. They generally report feeling well-prepared in...
This report was prepared under guidance from Gilbert Sylvia, Ph.D. Dr. Sylvia is president of SylDon Inc. located in Newport, Oregon and also Superintendent of the Coastal Oregon Marine Experiment Station, Oregon State University. Shannon Davis (President of The Research Group, Corvallis, Oregon) assisted Dr. Sylvia. The project was sponsored...
Understory vegetation communities are critical components of forest ecosystems. As a result, the importance of modeling understory vegetation characteristics in forested landscapes has become more apparent. Abundance measures such as shrub cover are bounded between 0 and 1, exhibit heteroscedastic error variance, and are often subject to spatial dependence. These...
The impact of mountains and ice sheets on the large-scale circulation of the world’s oceans is investigated in a series of simulations with a new coupled ocean–atmosphere model [Oregon State University–University of Victoria model (OSUVic)], in which the height of orography is scaled from 1.5 times the actual height (at...
Previously unaddressed aspects of how equatorial currents affect long Rossby wave phase speeds are investigated using solutions of the shallow-water equations linearized about quasi-realistic currents. Modification of the background potential vorticity (PV) gradient by curvature in the narrow equatorial currents is shown to play a role comparable to the Doppler...
In 2007, the City of Corvallis was issued a Phase II NPDES permit from the Oregon Department of Environmental Quality for non-point source pollution. In Corvallis, the majority of the stormwater conveyance system is separate from the sanitary sewer system. During a rain event, stormwater flows through pipes or over...
The operation of the Federal Columbia River Power System (FCRPS) has negatively affected threatened and endangered salmonid populations in the Pacific Northwest. Barging Snake River spring Chinook salmon Oncorhynchus tshawytscha through the FCRPS is one effort to mitigate the effect of the hydrosystem on juvenile salmon out-migration. However, little is...
