We spatially discretize the Sn transport equation using the high-order (HO) discontinuous finite element method (DFEM) on HO meshes. Previous work provided a proof-of-concept for this spatial discretization method in X-Y geometry. Included in the present work, we derive a spatial discretization for the Sn transport equation in both X-Y...
Declines in populations of anadromous salmonids (Oncorhynchus spp.) in the Columbia River drainage basin have resulted in extensive programs to annually release large numbers of hatchery-raised juvenile salmonids in an effort to support salmonid restoration. The Pacific Flyway population of Caspian terns (Hydroprogne caspia) has grown from around 3,500 nesting...
Recreational and Commercial fisheries and the quality of aquatic habitats in which the fish live are an important part of the livelihoods and economy of the Oregon Coast. The composition of important juvenile fish assemblages in estuaries can bring a unique view into the needs of different species on a...
Bridge inspection is a critical task needed to monitor bridge quality and serviceability. In the U.S., 40% of bridges are more than 50 years old while most bridges are typically designed for a lifespan of 50 years. 9.1% of the 614,387 bridges across the U.S are considered structurally deficient. These...
Women spend substantially more time on unpaid care work than men; they spend a vital part of the day trying to meet the social expectations of their domestic and reproductive roles. The goal of this study is to examine Nigerian women’s experience of housework as a form of unpaid labor....
Bacteria are critical to the health of eukaryotes and the ecosystems in which they persist. Some symbiotic interactions are mutualistic in which both microbe and host benefit from the partnership. Other interactions are parasitic, and the microbe typically benefits at a cost to the host. Rhodococcus is a genus of...
Casting manipulation in robotics is the act of launching a tethered projectile and using it to interact with the environment. One such interaction is wrapping a target. In this work, we identify throwing and tether control parameters for successfully wrapping a target with an end-weighted cable, evolving through a set...
The domestic cat is one of the world’s most popular companion animals. However, to date much remains to be learned about cat behavior and the cat-human relationship. To examine the influence of proximate factors on cat behavior and the human-cat bond, three studies were undertaken. Study 1 directly measured the...
Oregon State University Libraries and Press (OSULP) committed in its 2012-2017 strategic plan to the long term maintenance and preservation of digital content. OSULP manages digital objects in two Samvera repositories: the ScholarsArchive@OSU institutional repository, regularly ranked in the top ten U.S. repositories by Webometrics, and Oregon Digital, a longstanding...
The etiology and transmission of bacterial diarrheal pathogens is complex, making evaluating the association between extreme climate and diarrheal illnesses in North America challenging. Changes in climate may impact the survival, reproduction, and distribution of pathogens that cause diarrheal illness. Evidence supports the hypothesis that reproduction, survival, and transmission ability...
