Optimization of Schizochytrium limacinum SR21 Growth using Different Carbon Sources and Copper Concentrations

Creator:: Soo, Steven W.
Abstract:: The purpose of this project was to optimize the biomass growth of Schizochytrium limacinum SR21. This was achieved by studying the effect of various concentrations of glucose, use of pure glycerol and purified crude glycerol as alternative carbon sources, and inhibition of cell growth with the presence of copper. The...

Extensional characterization of weakly-viscoelastic fluids : methods & applications

Creator:: Marshall, Kristin A.
Abstract:: The addition of macromolecules to solvent, even in dilute quantities, can significantly alter a fluid's response in an extensional, or stretching, flow. When high-molecular-weight polymers are extended in solution, extensional thickening can result, yielding viscosities that are orders of magnitude larger than values found in shear. Examples of applications where...

Development of a Smartphone App to Easily Measure Extensional Viscosity

Creator:: Swift, Aleesha M.
Abstract:: The measurement of extensional viscosity is important in many chemical, biomedical, agricultural, and engineering applications. The determination of extensional viscosity is generally difficult, expensive, and inaccessible outside of research labs. The development of a smartphone application (app) that could use a phone’s high-speed camera to measure this parameter could open...

Production of C4-C10 Hydrocarbons from CO₂, H₂O, CO, H₂ and CH₄ Utilizing DC Glow Discharges, Catalytic Rapid Temperature Pulsing in Micro-Scale Reactors.

Creator:: Mohamed, Omar M.
Abstract:: This thesis experimentally determines the feasibility to creating C4 to C10 hydrocarbons from CO2, CO, H2, H2O and CH4. This is done in two steps, the initial step is the formation of ethylene through DC electrical glow discharge at ambient pressure while the second step is through temperature pulse controlled...

Analytical determination of copper speciation in Oregon highway runoff

Creator:: Sprick, Matthew S.
Abstract:: Low concentrations of dissolved copper have been shown to adversely affect the olfactory system of endangered salmonids, impairing their ability to avoid predators and likely increasing predation. It is believed that only the free ionic (Cu2+ free) and weakly complexed forms are bioavailable to organisms; these forms typically account for...

Study of graphite-polyurethane composite thin film electrodes for their use in electrochemical antifouling systems

Creator:: Delaney, Matthew A.
Abstract:: Prevention of marine biofouling is vital to the survivability and performance of ships, buoys, and wave energy devices. Coatings that contain metal biocides are currently used to prevent marine biofouling. These coatings have a limited lifetime and are under environmental scrutiny. As a result, it is necessary to research and...

Concentration Effects on Enhanced Particle Removal with Viscoelastic Fluids

Creator:: Cashen, Ryan K.
Abstract:: Highly elastic solutions have been shown to increase contaminant removal from silicon wafers, indicating the possibility for reduced reliance upon hazardous chemicals and expensive technologies during the fabrication of semiconductor devices. The onset of this enhanced removal is explored using rinsing and siphoning experimentswith polymer fluids of high molecular weights...

The rise of large gas bubbles through tubes filled with viscous liquids

Creator:: Brown, Gary Leigh
Abstract:: An analysis of the velocity and the shape of large gas bubbles rising through tubes filled with viscous liquids is presented. Four tubes, with diameters ranging from 0. 446 inches to 3. 97 inches, and three liquids, with viscosities ranging from one to 200 centipoise, were used in the study....

Development of a Paper-Based Whole Blood Phenylalanine Assay for PKU Diagnosis and Monitoring in Low Resource Settings

Creator:: Robinson, Robert Tyler
Abstract:: Phenylketonuria (PKU) is a genetic inborn metabolic disorder which inhibits the functional production of the enzyme phenylalanine hydroxylase (PAH). It currently affects one in 15,000 Americans and is the most common amino acid metabolism error found in newborns. Individuals affected with PKU are incapable of metabolizing the amino acid, phenylalanine...
