Quantitative, multi-spectral, light-transmission imaging of colloid transport in porous media at the meso scale

Creator:: Kraft, Erika Lorna
Abstract:: Colloids, particles smaller than ten microns in diameter, are ubiquitous in the subsurface. Colloids have an effect on the transport of contaminants that bind to their surfaces, and can reduce the permeability of aquifer materials through deposition. Some microorganisms, including pathogens, are also transported in the subsurface as colloids. The...

Conceptual Representations within the Social and Material Contexts of an Engineering Workplace and Academic Environments

Creator:: Barner, Matthew S.
Abstract:: Situated cognition theory emphasizes the role that social and material contexts have on learning and knowledge application. Several studies of engineering workplace environments have noted differences between the social and material contexts of the workplace and those of undergraduate engineering education. No existing research has studied the social and material...

Influence of the Environment and Morphology on Physiological and Genomic Homeostasis in a Temperate Cnidarian-microbe Symbiosis

Creator:: Koch, Jack C.
Abstract:: Climate change and other anthropogenic impacts are threatening the existence of millions of species around the globe. On western continental boundaries, the large-scale secondary process of upwelling, which brings low pH, deoxygenated, high nutrient seawater to the surface, is compounded by climate change, that together could drive some species to...

Disengaged and untrusting? Young adults' feelings of social integration and trust during the Great Recession

Creator:: Day, Jack K.
Abstract:: Navigating the transition to adulthood is fraught with challenges, especially for those coming of age during an economic crisis. Individuals often rely on support from existing social networks, and establish social capital through deepening and expanding social ties, as they establish footholds in roles marking adulthood. Yet investing in social...

Breeding tomatoes for improved antioxidant activity

Creator:: Mes, Peter Jack, 1976-
Abstract:: Purple tomatoes (Lycopersicon esculemtum) were bred by incorporating genes that result in anthocyanin production in the skin of fruits. These genes originally came from related wild species as no naturally occurring genes encoding fruit anthocyanin expression are known within the cultivated species. By combining Aft or Abg with atv or...

The relationships between fluctuations in oceanographic conditions, forage fishes, predatory fishes, predator food habits, and juvenile salmonid marine survival off the Columbia River

Creator:: Emmett, Robert L.
Abstract:: Salmonid run sizes are strongly affected by their early marine stage. Fully understanding the life history of salmonids means understanding how they interact with their marine environment and with other fishes. Changes in the biological and physical environment off the Columbia River region affects the distribution and abundance of predatory...

Agricultural erosion and sediment in the western Willamette Valley as indicated by redistribution of Cesium-137

Creator:: Brown, R. B. (Randall Barber)
Abstract:: Modern agricultural erosion was studied using ¹³⁷Cs from fallout as an indicator of erosion/deposition. The study area was a 285 ha agricultural watershed in the hilly western margin of the Willamette Valley, a high winter rainfall zone in which fall-planted crops are commonly grown. Objectives of the study were (i)...

Ecosystem Functions of Pacific Northwest Estuaries: The Role of Ocean and Watershed Drivers in Eelgrass and Coho Salmon Dynamics

Creator:: Magel, Caitlin L.
Abstract:: Interest is expanding for the potential role of estuaries, particularly seagrass and salt marsh habitats, to sequester carbon, mitigate ocean acidification, and support abundant fisheries. The important functions of estuaries are part of a broader set of ecosystem services, or benefits to humans, which are regulated by ocean and watershed...

Decision support systems for forest biodiversity management : a review of tools and an analytical-deliberative framework for understanding their successful application

Creator:: Gordon, Sean N.
Abstract:: The complexity of forest management has increased with the scope of resources of concern and the level of scrutiny from stakeholders. The design and use of specialized computer software, often referred to as “decision support systems” (DSS), is one method for helping managers deal with this complexity. DSS have proven...

Spatial patterns of fuel management activities and their effects on wildfire behavior

Creator:: Kim, Young-Hwan
Abstract:: Fuel management has been used as an effective local strategy to reduce the undesirable consequences of wildfires. Many efforts toward scheduling of fuel management activities across a broader landscape have been proposed, with the hope of achieving larger landscape-scale management effects. However, scheduling of fuel management treatments across the broader...
