Self Assembly of GeO₂ Nanoparticles: A Biomimetic Approach

Creator:: Gessford, Makayla SueAnn Fu Ting
Abstract:: Diatoms are single celled eukaryotic microalgae that self-assemble complex SiO₂ nanostructures by sillafin proteins within their cell wall. There has been increasing interest in mimicking the diatom’s silica self-assembly process for fabricating metal oxide nanoparticles, namely germanium dioxide (GeO₂). GeO₂ has a higher refractive index than silica, enabling it to...

Traditional Native American Healing in Modern Medicine

Creator:: Faulkner, Jaime E.
Abstract:: From the formation of reservations, Native Americans have faced many difficulties and continue to deal with cultural barriers today. Particularly within a medical setting, there is a worldview disconnect between western medicine and traditional Native healing. It would be useful to interview Native pupils to learn about their uses of...

Effects of Channel and Ratchet Geometry on Passive Pumping in an Open-ended channel Configuration

Creator:: Daniels, Mitchell A.
Abstract:: Modern electronics have created increased demand for innovative cooling solutions. Typical forced convective cooling systems consist of pumps that circulate cooling fluid. However pumps can be unwieldy for many applications. This research is a continuation of work done at Oregon State University and Auburn University on the passive pumping of...

Retrospective study of the prevalence of Pseudoloma neurophilia between zebrafish sexes

Creator:: Chow, Fidelis
Abstract:: As a major biological model for biomedical research, maintaining healthy zebrafish (Danio rerio) is imperative for accurate and consistent lab results. This retrospective study focuses on Pseudoloma neurophilia, a microsporidium, because it is the most common pathogen found in laboratory zebrafish. An online database maintained by the Zebrafish International Resource...

Abundances of raptors wintering in the Willamette Valley, Oregon, before and after a ban on grass field burning

Creator:: Caldwell, Stephanie E.
Abstract:: For the past 50 years, open-field burning has served as the main method to manage postharvest residue in grass seed fields within the Willamette Valley. Recently, farmers have implemented the full straw load and clean-nonthermal methods to remove straw after harvest. We hypothesized that these two alternative methods have caused...

Methods for Eliciting Adoption of Alternative Agricultural Practices : Application to Climate Change

Creator:: Burkum, Kelsey
Abstract:: As the climate conditions in regions shift, research seeks to gain more understanding of agricultural producers’ behavioral choices specifically in relation to climate change and alternative practices. This research aims to compare elicitation tools to find the most appropriate method to elicit agricultural producers’ choices and attitudes toward changing production...

Isotopic Analysis of Diet Specificity in the Chisel-toothed Kangaroo Rat, Dipodomys microps

Creator:: Guerre, Megan E.
Abstract:: Rapid changes in global climate have put many species at risk, particularly niche specialists. The Chisel-toothed kangaroo rat, Dipodomys microps, is thought to specialize on the desert shrub Atriplex confertifolia. Because of this close relationship, D. microps was presumed to have tracked the shrub as its distribution shifted south during...

Interaction of Design Factors in the Truckload Relay Network Design with Mixed Fleet Dispatching Problem

Creator:: Jenks, Christopher L.
Abstract:: Truckload carriers operating under a Point-To-Point (PtP) dispatching method seek to minimize miles driven with empty loads. This results in driving tours keeping drivers away from their homes for weeks at a time causing high turnover rates industry wide. One proposed solution combines Relay Network dispatching with existing PtP. This...

Facilitators and Barriers to Contraceptive Use among College-Age Latinas: Listening to Student Health Care Providers

Creator:: Farr, Carly Michelle
Abstract:: This study explored factors that affect acquisition and proper use of contraception among the college-age Latina population at Oregon State University. Interviews were conducted with eleven health care providers at OSU’s Student Health Services during the spring of 2014. Using content analysis we identified individual-level barriers including lack of knowledge...

Evaluating the Toxicity of Organophosphate Flame Retardants in Zebrafish

Creator:: Britsch, Kimberly A.
Abstract:: Flame retardants are in many home products including couches, chairs, and electronics. The most commonly used flame retardants contained polybrominated diphenyl ethers (PBDEs) until 2004, when the majority of these chemicals were phased out. PBDEs were found to be persistent, bioaccumulative, and toxic to both humans and the environment. Organophosphate...

Evidence for the Potential Hybridization of Ammophila breviligulata and Ammophila arenaria in the Pacific Northwest.

Creator:: Borland, Joshua J.
Abstract:: Coastal dunes are dynamic and unique ecosystems. On the Pacific coast, dunes are generally dominated by the beach grasses, Ammophila breviligulata and Ammophila arenaria, two invasive species introduced in the early 1900’s to stabilize sand and create foredunes that serve to protect people who live behind them. Recently, a novel...

The Effect of Drainage Flow Rate on Fluid Connectivity; Application to Geologic CO₂ Sequestration

Creator:: Bertoch, Madison
Abstract:: Geologic CO₂ sequestration is a climate change mitigation strategy that involves the injection of supercritical CO₂ into deep underground rock formations. This thesis focuses on capillary trapping in which capillary forces immobilize CO₂ bubbles at the pore scale. During injection of supercritical CO₂, brine is displaced in what is known...

Calculating the Added Cost of Over-Densifying Particleboard

Creator:: Gardner, Ben
Abstract:: Particleboard is a commodity composite panel made from the residual materials of other wood products manufacturing companies. The industry operates on low profit margins and thus produces high volumes of differing panel grades. Slight inefficiencies over the course of a year can mean a significant loss in profit. Previous calculations...
