Advection-diffusion in inertial flow through periodically converging-diverging tubes

Creator:: Lambert, Adam
Abstract:: A direct numerical simulation of advection-diffusion in a sinusoidal tube was carried out using the commercial ﬁnite-volume code STAR-CD. The Reynolds numbers varied from Re = 0.1 to Re = 14.5. At the larger Reynolds numbers, steady-state eddies formed in the diverging sections and significantly inﬂuenced the macroscale dispersion. Long...

Analysis of Chemical Leaching from Common Consumer Plastic Bottles Under High Stress Conditions

Creator:: Dornath, Paul John
Abstract:: There has been much controversy in recent years over the leaching of chemicals from plastic water bottles. In this study, two of the most common plastics used in water bottles, polyethylene terphthalate (PETE) and polycarbonate (PC) were studied. The leaching of the chemical bisphenol-A (BPA) from polycarbonate (Nalgene ™, Camelback...

Conversion of biomass constituents to hydrogen-rich gas by supercritical water in a microchannel reactor

Creator:: Goodwin, Aaron K.
Abstract:: Microreactors offer high rates of heat transfer able to intensify highly endothermic biomass reforming reactions in supercritical water. In this study, two continuous flow microreactor configurations were used to gasify biomass constituents in supercritical water. The first reactor configuration was a micro diameter stainless steel or Hastelloy tube (508 µm...

Downstream processing of microalgal biomass for biofuels

Creator:: Sander, Kyle B.
Abstract:: This thesis documents the work carried out investigating the downstream processing of algal biomass for biofuel production. A life cycle assessment was conducted on a hypothetical algal biodiesel process in which it was found drum drying and cell component separation were life cycle intensive processes. A laboratory experiment was conducted...

Enhanced Delivery of Cryoprotectant Chemicals to Cultured Neurons

Creator:: Wilson, Jenna L.
Abstract:: Due to the many advances in the areas of biotechnology and medicine, the need for long- term storage and stabilization of biological materials is rapidly increasing. The field of biopreservation is attempting to address these issues by finding ways to maintain the integrity and functionality of proteins, cells, and organs...

Evaluation of feedstocks for cellulosic ethanol and bioproducts production in the Northwest

Creator:: Miller, Wesley C. (Wesley Clair)
Abstract:: Cellulosic ethanol production for transportation fuel is one source to help satisfy the increasing worldwide demand for energy and depletion of the fossil fuel supply. Evaluating potential production from plants and waste in Oregon, Washington and Idaho is the purpose of this study. Reed Canary grass, Annual Ryegrass, wheat straw,...

Initial velocity analyses of milling effects on rates of enzyme-catalyzed saccharification of native wheat straw

Creator:: Nguyen, Quynh M.
Abstract:: There is considerable interest in developing environmentally friendly processes for the economical conversion of biomass plant material to biofuels, bioproducts and biomaterials. One approach to such a conversion process is to make use of enzymes for the conversion of plant polysaccharides to simple sugars; the simple sugars could then be...

Optimizing the performance of gypsum wall board in wood frame shear walls

Creator:: Goodall, Scott I.
Abstract:: The overall goal of this project was to design a wood frame shear wall that could withstand greater displacement before damage occurred to the Gypsum Wall Board (GWB). More specifically, the objectives of the study were: (1) to evaluate damage to the GWB in alternative shear wall designs at 1%,...

The effects of single and multiple pathogen and parasite infections on juvenile chinook and coho salmon during early marine residency

Creator:: Sandell, Todd A.
Abstract:: Nearly 3000 juvenile Chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon captured in nearshore waters off the coasts of Washington and Oregon from 1999-2004 were tested for infection by Renibacterium salmoninarum, Nanophyetus salmincola, and skin metacercariae. First, three quantitative PCR primer/probe sets were compared for detection of R. salmoninarum; amplification...

Two-stage photobioreactor cultivation for enhancing lipid production from diatom cells by controlled silicon limitation

Creator:: Rosenberger, Jennifer L.
Abstract:: There is significant interest in utilizing microalgae as a source for biofuels. Diatoms are a class of single-celled microalgae which make silica cell walls and require dissolved silicon as a substrate for cell division. Manipulation of soluble silicon delivery to the culture offers a route to control cell cycle and...
