Impact of biased movement on marine protected area effectiveness

Creator:: Rekow, James Alexander
Abstract:: Fish mobility affects the distribution of commercially caught fish species in marine protected areas (MPAs) and unprotected areas, which we will call fishing grounds (FGs). Previous theoretical findings predicted that highly mobile fish would benefit little if at all from protection in MPAs (Demartini 1993, Walters et al. 1999). However,...

Persistence of Populations in Environments with an Interface

Creator:: Rekow, James A.
Abstract:: We model a fish population in a spatial region comprising a marine protected area and a fishing ground separated by an interface. The model assumes conservation of biomass density and takes the form of a reaction diffusion equation with a logistic reaction term. At the interface, in addition to continuity...

Verifying safe use of a thinner aluminum scattering chamber for fission physics

Creator:: Porter, Eben, Jr.
Abstract:: This thesis describes calculations done to determine the radiation hazard of the current Prompt Gamma Neutron Activation Analysis (PGNAA) scattering chamber at the Oregon State TRIGA Reactor (OSTR) and compare it to the amount that would be given off by a new thin-walled chamber design. These calculations were completed with...

Efficacy of Cultural Practices for Mitigating the Negative Impacts of Grapevine Red Blotch Virus on Vine Physiology and Fruit Composition in Oregon Pinot Noir

Creator:: Copp, Cody R.
Abstract:: The recently emerged Grapevine Red Botch Virus (GRBV) impedes proper berry ripening primarily by reducing sugar accumulation and color development in red-fruited Vitis vinifera L. cultivars. To date, there is no recommended management strategy for virus spread or the impacts of the disease beyond removal and replacement of infected vines....

The energy extraction performance of an oscillating rigid and flexible foil

Creator:: Totpal, Alexander D.
Abstract:: The aerodynamic performance of an oscillating pitching and plunging foil operating in the energy harvesting mode is investigated. Experiments are conducted in a closed-loop recirculating wind tunnel at Reynolds numbers of 24,000 to 48,000, and reduced frequencies (k = fc/u) of 0.042 to 0.083. Foil kinematics are varied through the...

From the Classroom to the Boardroom: Behaviors Associated with Both Student Leader and Business Leader Effectiveness

Creator:: Dodge, Miles
Abstract:: Each year thousands of college graduates enter the business world armed with skills accumulated as student leaders, but how applicable are these skills to the business world? While there are many studies on learnable behaviors associated with effective student leadership and many studies on behaviors associated with effective business leadership,...

Value of Prior and Novel Information in Managing a Mixed-Stock Recreational Chinook Salmon Fishery

Creator:: Jensen, Alexander J.
Abstract:: Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...

Development of an accurate Monte Carlo treatment plan calculation framework for the purpose of developing dose calculation error predictors for a widely implemented clinical algorithm

Creator:: Egan, Alexander J.
Abstract:: Monte Carlo (MC) algorithms are widely accepted as the most accurate method to calculate dose in a patient geometry. For this work the EGSnrc MC code was used as a benchmark for the identification of dose calculation errors produced by the widely implemented analytical anisotropic algorithm (AAA). By correlating the...

Dynamical System Scaling of Fuel Performance During Reactivity Insertion Accidents

Creator:: Dueñas, Alexander M.
Abstract:: Fuel qualification timelines for new fuel technology under ideal conditions can take between 20-25 years to be fully qualified from initial concept to deployment as full fuel assemblies. To reduce the timeline and costs, new separate-effects test and integral-effects test experiments, advanced instrumentation, and advanced modeling and simulation tools are...

Transport and Mixing of Buoyant Water from Small Mountainous Rivers : An Investigation of Estuarine Residence Timescales and Coastal Current Propagation

Creator:: Lemagie, Emily P.
Abstract:: Small rivers, such as those that line the Oregon coast, have been shown to deliver significant concentrations of suspended sediments and nutrients to estuaries and the coastal ocean during wet seasons during which winds are predominantly downwelling-favorable. The fate of the buoyant source water and of any suspended or dissolved...
