Optimization under Uncertainty of a Magnetohydrodynamics Generator

Creator:: Rajbhandari, Evan
Abstract:: Within this dissertation, we develop tools and techniques to demonstrate the feasibility of real-time optimization of a magnetohydrodynamics generator. To ease computational complexity, we work on the kinematic magnetohydrodynamic system, prescribing the ﬂuid-ﬂow and model the material response of the system through an updated Generalized Ohm’s law. We focus on...

A theoretical description of anisotropic chemical association and its application to hydrogen-bonded fluids

Creator:: Peery, Travis B.
Abstract:: The thermodynamic and structural effects of highly anisotropic, short-ranged attraction are investigated for single- and four-site interaction models using Wertheim's multi-density graph theory of chemical association. Both models consist of associating hard spheres, where the saturable attraction sites are described by conical wells centered in the hard core and evaluated...

The effect of PACE on self-reported anxiety and performance in first year nursing students

Creator:: Irving, Jan Louise
Abstract:: The purpose of this study was (a) to determine the effect of a four-step learner readiness profile: positive, active, clear, and energetic (PACE) on self-reported anxiety in first year nursing students before skill performance tests, and (b) to determine the effect of PACE on the performance of first year nursing...

Numerical Simulations and Microscale Analyses of Offshore Anchor-Granular Material Systems

Creator:: Zhang, Nan
Abstract:: Anchoring systems are used to hold floating offshore devices (e.g., energy devices, oil platforms) to keep them on their stations. Anchors are embedded into the seabed soils. In some cases, the interface shear between anchor and seabed soils together with anchor self-weight provide the holding capacity of the anchoring systems....

The relationship between the cerebral lateralization for Arabic language and achievement in science

Creator:: Hafez, Abdullah Ibrahim M.
Abstract:: The major purpose of this study was to test the relationship between students' cerebral lateralization for the Arabic language and their achievement in science. A secondary purpose was to investigate handedness as a factor in that relationship. The experiment was conducted in the City of Jeddah, Saudi Arabia, using dichotic...

A New Bonding Model for the Particulate Simulation of Bio-Cemented Sand (with a Side Excursion on Percolation in Granular Mixtures)

Creator:: Khoubani, Ali
Abstract:: Bio-cementation is a promising method for the liquefiable mitigation of loose saturated sands. In the improvement process a bacterium that can be found naturally in soil deposits is fed urea. The bacterium consumes and breaks down the urea to form ammonium and carbonate. In the presence of calcium, calcium carbonate...

Regulation of Redox Homeostasis in Skin Cells for the Prevention of UV-Induced Stress and Treatment of Melanoma

Creator:: Carpenter, Evan L.
Abstract:: Melanocytes are dendritic, pigment-producing cells located in the skin and are responsible for its protection against the deleterious effects of solar ultraviolet radiation (UVR), which include DNA damage and elevated reactive oxygen species (ROS). They do so by synthesizing photoprotective melanin pigments and distributing them to adjacent skin cells (e.g.,...

Jumping in with Both Feet: Exploring Factors that Shape Juvenile Amphibian Movement

Creator:: Bredeweg, Evan M.
Abstract:: Investigation into how animals move within the landscape is important for both understanding of ecological processes and conservation management. Animal movement is important in shaping life history transitions, demographics, individual fitness, and species distributions. However, as landscapes become increasingly affected by human activities, movement becomes important as species navigate landscapes...

Examining School-Day Physical Activity Opportunities and the Influence of Physical Activity at School on Weight Status in Rural Oregon Elementary School Children

Creator:: Hilberg, Evan M.
Abstract:: There is a known relationship between total physical activity (PA) and weight status in children; however, there is a paucity of data examining the prospective relationship between school day PA and obesity among rural elementary school children. A large number of cross-sectional studies have demonstrated that higher levels of PA...

The Ecophysiology of Thiamine Deficiency Complex : Evaluating Sources of Thiaminase in Great Lakes Food Webs

Creator:: Evans, Allison N.
Abstract:: Thiamine (vitamin B₁) is required by all living organisms for carbohydrate metabolism and synthesis of amino acids. Thiamine deficiency is responsible for several related classes of early life stage mortality disorders in salmonines, including Thiamine Deficiency Complex (TDC) in the Laurentian Great Lakes, Cayuga Syndrome in the Finger Lakes, and...
