Quantitative Study of Math Excel Calculus Courses

Creator:: Watkins, Christopher H.
Abstract:: About twenty years ago, a large, rural, doctoral granting institution with an undergraduate population of approximately 24,000 in the pacific northwest of the United States established the Math Excel program. Students would attend lectures three times a week for 50 minutes like a traditional course, and they would also attend...

Reassessment of Grading Criteria with Respect to the Flexural Properties of Douglas-fir Crossarms

Creator:: Anderson, Christopher H.
Abstract:: Wood plays a key role in modern electrical infrastructure; crossarms and power poles utilize the high strength to weight ratio, availability and low cost of wood to facilitate the access of power to millions of Americans. However, wood presents a variety of challenges as a material. In structural applications, one...

A novel framework for uncertainty propagation in river systems based on performance graphs using two-dimensional hydrodynamic modeling

Creator:: Gifford-Miears, Christopher H.
Abstract:: This thesis presents a novel approach for propagation of uncertainty in river systems. Errors in data observations and predictions (e.g., stream inflows), in model parameters, and resulting from the discretization of continuous systems, all point to the need to accurately quantify the amount of uncertainty carried through the modeling process....

Addition of inorganic or organic phosphorus enhances nitrogen and carbon fixation in the oligotrophic North Pacific

Creator:: Watkins-Brandt, Katie S., Letelier, Ricardo M., Spitz, Yvette H., Church, Matthew J., Böttjer, Daniela, and White, Angelicque E.
Abstract:: We present a spatially extensive record of dinitrogen (N₂) fixation rates and distributions of N₂ fixing microorganisms along with the results of exogenous phosphorus (P) addition experiments conducted during a series of cruises in the North Pacific Subtropical Gyre (NPSG). We measured the N₂ and carbon (C) fixation rates of...

Modeling Implantable Passive Mechanisms for Modifying the Transmission of Forces and Movements Between Muscle and Tendons

Creator:: Homayouni, Taymaz, Underwood, Kelsey N., Beyer, Kamin C., Martin, Elon R., Allan, Christopher H., and Balasubramanian, Ravi
Abstract:: This paper explores the development of biomechanical models for evaluating a new class of passive mechanical implants for orthopedic surgery. The proposed implants take the form of passive engineered mechanisms, and will be used to improve the functional attachment of muscles to tendons and bone by modifying the transmission of...

Evaluating spatial patterns of drought-induced tree mortality in a coastal California pine forest

Creator:: Baguskas, Sara A., Peterson, Seth H., Bookhagen, Bodo, and Still, Christopher J.
Abstract:: In a coastal, fog-influenced forest on Santa Cruz Island in southern California, we observed mortality of Bishop pine (Pinus muricata D.Don) trees following a brief (2 year), yet intense, drought. While anecdotal evidence indicates that drought-induced Bishop pine mortality has occurred in the past in the stand we studied, this...

Spatial Ecological Processes and Local Factors Predict the Distribution and Abundance of Spawning by Steelhead (Oncorhynchus mykiss) across a Complex Riverscape

Creator:: Falke, Jeffrey A., Dunham, Jason B., Jordan, Christopher E., McNyset, Kristina M., and Reeves, Gordon H.
Abstract:: Processes that influence habitat selection in landscapes involve the interaction of habitat composition and configuration and are particularly important for species with complex life cycles. We assessed the relative influence of landscape spatial processes and local habitat characteristics on patterns in the distribution and abundance of spawning steelhead (Oncorhynchus mykiss),...

The Plant Actin Cytoskeleton Responds to Signals from Microbe-Associated Molecular Patterns

Creator:: Henty-Ridilla, Jessica L., Shimono, Masaki, Li, Jiejie, Chang, Jeff H., Day, Brad, and Staiger, Christopher J.
Abstract:: Plants are constantly exposed to a large and diverse array of microbes; however, most plants are immune to the majority of potential invaders and susceptible to only a small subset of pathogens. The cytoskeleton comprises a dynamic intracellular framework that responds rapidly to biotic stresses and supports numerous fundamental cellular...

Switching Hemispheres: A New Migration Strategy for the Disjunct Argentinean Breeding Population of Barn Swallow (Hirundo rustica)

Creator:: Garcia-Perez, Belen, Hobson, Keith A., Powell, Rebecca L., Still, Christopher J., and Huber, Gernot H.
Abstract:: Background: Barn Swallows (Hirundo rustica) breed almost exclusively in the Northern Hemisphere. However, since the early 1980's, a small disjunct breeding population has become established in eastern Argentina, presumably by birds previously derived from those breeding in North America. Currently, it is unknown where these individuals go following breeding and...

Air-Sea Interactions from Westerly Wind Bursts During the November 2011 MJO in the Indian Ocean

Creator:: Moum, James N., de Szoeke, Simon P., Smyth, William D., Edson, James B., DeWitt, H. Langley, Moulin, Aurélie J., Thompson, Elizabeth J., Zappa, Christopher J., Rutledge, Steven A., Johnson, Richard H., and Fairall, Christopher W.
Abstract:: The life cycles of three Madden–Julian oscillation (MJO) events were observed over the Indian Ocean as part of the Dynamics of the MJO (DYNAMO) experiment. During November 2011 near 0°, 80°E, the site of the research vessel Roger Revelle, the authors observed intense multiscale interactions within an MJO convective envelope,...
