Development and Operation of a Self-Refueling Compressed Natural Gas Vehicle

Creator:: Elgin, Robert C., III and Hagen, Christopher L.
Abstract:: A dual-mode engine has been developed where in one mode all engine cylinders fire normally, providing locomotion for the vehicle. In the other mode, one cylinder of the engine is used to compress low pressure residential natural gas (NG), in multiple stages, to a standard U.S. compressed natural gas (CNG)...

Interpretation and design of ocean acidification experiments in upwelling systems in the context of carbonate chemistry co-variation with temperature and oxygen

Creator:: Reum, Jonathan C. P., Alin, Simone R., Harvey, Chris J., Bednaršek, Nina, Evans, Wiley, Feely, Richard A., Hales, Burke, Lucey, Noelle, Mathis, Jeremy T., McElhany, Paul, Newton, Jan, and Sabine, Christopher L.
Abstract:: Coastal upwelling regimes are some of the most productive ecosystems in the ocean but are also among the most vulnerable to ocean acidification (OA) due to naturally high background concentrations of CO₂. Yet our ability to predict how these ecosystems will respond to additional CO₂ resulting from anthropogenic emissions is...

Cool, Pathogen-Free Refuge Lowers Pathogen-Associated Prespawn Mortality of Willamette River Chinook Salmon

Creator:: Benda, Susan E., Naughton, George P., Caudill, Christopher C., Kent, Michael L., and Schreck, Carl B.
Abstract:: Spring Chinook Salmon Oncorhynchus tshawytscha are transported above dams in the Willamette River to provide access to blocked spawning habitat. However, 30–95% of these transplants may die before spawning in some years. To varying degrees, salmon in other tributaries—both blocked and unblocked—have similar prespawn mortality (PSM) rates. Our study determined...

Large-Scale Downy Brome Treatments Alter Plant-Soil Relationships and Promote Perennial Grasses in Salt Desert Shrublands

Creator:: Schantz, Merilynn C., Monaco, Thomas A., Call, Christopher A., and Sheley, R. L.
Abstract:: Because invasive annual grasses can strongly influence soil resource availability and disturbance regimes to favor their own persistence, there is a great need to understand the interrelationships among invasive plant abundance, resource availability, and desirable species prominence. These interrelationships were studied in two salt desert sites where the local abundance...

Geostrophic Velocity Measurement Techniques for the Meridional Overturning Circulation and Meridional Heat Transport in the South Atlantic

Creator:: Perez, Renellys C., Garzoli, Silvia L., Meinen, Christopher S., and Matano, Ricardo P.
Abstract:: Two ocean general circulation models are used to test the ability of geostrophic velocity measurement systems to observe the meridional overturning circulation (MOC) and meridional heat transport (MHT) in the South Atlantic. Model sampling experiments are conducted at five latitudes (between 15° and 34.5°S) spanning the range of extratropical current...

Total Lipids, Lipid Classes, and Fatty Acids of Newly Settled Red King Crab (Paralithodes camtschaticus): Comparison of hatchery-cultured and wild crabs

Creator:: Copeman, Louise A., Stoner, Allan W., Ottmar, Michele L., Daly, Benjamin, Parrish, Christopher C., and Eckert, Ginny L.
Abstract:: Little is known about the nutrition or lipid metabolism of cold-water crabs, particularly in the North Pacific. We undertook a 2-part study to understand more completely the energetics and nutritional requirements of juvenile red king crab (RKC; Paralithodes canusehaticus). First, we investigated changes in proximate composition, total lipids (TLs), lipid...

Reduction in carbon uptake during turn of the century drought in western North America

Creator:: Schwalm, Christopher R., Williams, Christopher A., Schaefer, Kevin, Baldocchi, Dennis D., Black, T. Andrew, Goldstein, Allen H., Law, Beverly E., Oechel, Walter C., Paw U, Kyaw Tha, and Scott, Russel L.
Abstract:: Fossil fuel emissions aside, temperate North America is a net sink of carbon dioxide at present¹⁻³. Year-to-year variations in this carbon sink are linked to variations in hydroclimate that affect net ecosystem productivity³,⁴. The severity and incidence of climatic extremes, including drought, have increased as a result of climate warming⁵⁻⁸....

Subclinical Vascular Disease Burden and Longer Survival

Creator:: Odden, Michelle C., Yee, Laura M., Arnold, Alice M., Sanders, Jason L., Hirsch, Calvin, deFilippi, Christopher, Kizer, Jorge R., Inzitari, Marco, and Newman, Anne B.
Abstract:: OBJECTIVES: Subclinical vascular disease (SVD) contributes to the aging process and may decrease life expectancy. We aimed to determine the contribution of gradations of SVD to the likelihood of achieving longer survival, and to determine what allows some individuals to achieve longer survival in the presence of high SVD. DESIGN:...

Establishment of a Statewide Network for Carbapenem-Resistant Enterobacteriaceae Prevention in a Low-Incidence Region

Creator:: Pfeiffer, Christopher D., Cunningham, Margaret C., Poissant, Tasha, Furuno, Jon P., Townes, John M., Leitz, Andrew, Thomas, Ann, Buser, Genevieve L., Arao, Robert F., and Beldavs, Zintars G.
Abstract:: OBJECTIVE: To establish a statewide network to detect, control, and prevent the spread of carbapenem-resistant Enterobacteriaceae (CRE) in a region with a low incidence of CRE infection. DESIGN: Implementation of the Drug Resistant Organism Prevention and Coordinated Regional Epidemiology (DROP-CRE) Network. SETTING AND PARTICIPANTS: Oregon infection prevention and microbiology laboratory...

Status and Ecological Effects of the World’s Largest Carnivores

Creator:: Ripple, William J., Estes, James A., Beschta, Robert L., Wilmers, Christopher C., Ritchie, Euan G., Hebblewhite, Mark, Berger, Joel, Elmhagen, Bodil, Letnic, Mike, Nelson, Michael P., Schmitz, Oswald J., Smith, Douglas W., Wallach, Arian D., and Wirsing, Aaron J.
Abstract:: Large carnivores face serious threats and are experiencing massive declines in their populations and geographic ranges around the world. We highlight how these threats have affected the conservation status and ecological functioning of the 31 largest mammalian carnivores on Earth. Consistent with theory, empirical studies increasingly show that large carnivores...
