The role of phenolics in anode fouling during electrolysis of aqueous alkali byproduct streams from food and agricultural processing

Creator:: Dulaney, Anthony
Abstract:: The research revolves around membrane-assisted electrolysis to recover caustic soda from alkali processing. This research began with the lab having no experience in electrochemistry and thus conducting initial experiments to begin to understand electrochemical systems. The lab then looked at both gas production and anodic fouling behavior. The lab then...

The effects of gamma radiation on Cascade hop

Creator:: Getty, Brooke
Abstract:: This gamma irradiation study was conducted to establish an LD50 of the hop (Humulus lupulus L.) cultivar Cascade . The overall, long term goal is to generate replacement hop cultivars by inducing minor but significant DNA alterations with gamma radiation to improve agronomic quality without changing the brewing profile. The...

Sociability in bottle fed vs mother fed lambs

Creator:: Longrie, Kelsey
Abstract:: In this study, we compared the behavior of bottle fed lambs verses mother fed lambs in three testing scenarios; the sociability test, the paired attachment test, and the mismatch attachment test. The tests sought to determine if a familiar human can serve as a secure base for lambs in a...

Relationship Between Winter Downwelling Conditions and Summer Hypoxia Severity Along the Oregon Coast

Creator:: Walters, Helen Marie
Abstract:: Hypoxia is a naturally occurring phenomenon that happens seasonally off the Oregon coast. As a consequence, there has been a great deal of research focused around analyzing the strength and duration of the hypoxic event during the summer season. This paper, however, takes an innovative approach by looking at the...

Preliminary Examination of the socioeconomic and housing factors that influence exposure to flame-retardants (FRs) in passive samplers worn by preschool-aged children in Oregon

Creator:: Willard, Kenneth
Abstract:: Abstract Flame-retardants (FRs) generally enter the environment by dissociating from the products they were originally manufactured into. The predominant class of FR used in consumer products before their eventual phase-out in the mid-2000s were the polybrominated diphenyl ethers (PBDEs). Previous studies have illustrated a correlation between socio-economic status, notably gross...

Photoactuated Droplet Microfluidics Enabled via Spiropyrans

Creator:: Lee, Jamy
Abstract:: Spiropyrans are a family of photosensitive molecules their hydrophobic properties when irradiated with light. Since spiropyran can be controlled by light, it can be used to regulate transport across membrane media. The ability to control the release of a substance onto a platform is promising in reducing the cost of...

Monitoring the effects of oak woodland restoration on birds in the Willamette Valley, Oregon

Creator:: Martinez, Elena
Abstract:: Oregon White Oaks (Quercus garryana) were once abundant in the Willamette Valley, Oregon, but have drastically decreased because of fire suppression, agriculture, and human development. Oaks are an important ecosystem because they provide a diverse habitat for bird species that are insectivorous and/or cavity nesters. We studied the oak restoration...

Investigations of Pactamycin Biosynthesis

Creator:: Osborn, Andrew
Abstract:: Pactamycin, a complex aminocyclitol compound produced by Streptomyces pactum, has significant antibiotic, antitumor, and antiplasmodial activity. However, this natural product has not been developed for clinical use due to its high cytotoxicity. Modulation of its biological properties by chemical synthesis has been difficult due to its complex chemical structure. Therefore,...

Investigation of Crangon spawning behavior, assemblage, and trophic relationships in the estuarine and shelf habitats of the central Oregon coast

Creator:: Danilchik, Nikolai M., Huff, David D., Loewenherz, Larkin, and Henkel, Sarah K.
Abstract:: A better understanding of the distribution and spawning behavior of Crangon shrimp and their relationship with their predators, including the green sturgeon, Acipenser medirostris, is an important step toward the larger goal to understand food webs of the nearshore continental shelf of the northeastern Pacific. Here, I examined how the...

Host Specificity Among Closely Related Dinoflagellates: Using Autofluorescence to Enumerate Symbionts in Aiptasia

Creator:: Corey, Kevin R., Kirk, N. L., Meyer, E., Coffroth, M. A., and Weis, V. M.
Abstract:: Symbiotic relationships between cnidarians and dinoflagellates within the genus Symbiodinium are critically important for the success of coral reefs. These symbionts provide their hosts with photosynthetically-fixed carbon in exchange for nutrients and shelter. Symbiodinium is a phylogenetically diverse genus that is often typed by sequencing the ribosomal internal transcribed spacer...

Ecosystem Analysis of Wetland and Riparian Zone restoration at the Hart Mountain Antelope Refuge over Twenty Years

Creator:: Reis, Schyler Ainsworth
Abstract:: Hart Mountain National Antelope Refuge (HMNAR) established in 1936, is 101,000 ha in area. The refuge was grazed by domestic livestock from the 1870s until their exclusion in 1990. Just prior to removal of livestock, photopoints were taken at various riparian and wetland locations throughout the refuge to document riparian...

Does combining moss and Sedum improve functional performance of green roofs in the Pacific Northwest?

Creator:: VanHoosen, Amelia
Abstract:: There are a number of problems associated with urban expansion and as cities continue to grow the integration of green roofs can help to ease and offset many of them. This study uses a combination of moss and Sedum as vegetation for experimental green roof sections in order to test...

Differential aggression between aggregations of the clonal sea anemone Anthopleura elegantissima on the Oregon Coast

Creator:: Gonzalez, Xavier
Abstract:: A. Elegantissima is not well understood, there is still much we don’t know about the anemone. What we do know is that they live in aggregations, where they divide the labor as mothers and warriors. The anemones have feeding tentacles and acrorhagi, the latter are attacking tentacles. Mothers are found...

Development, adaptation and testing of remote, non-powered sampling systems fortemporal characterization of hydraulically fractured shale systems

Creator:: Neumann, Kyle
Abstract:: Extraction of natural gas from shale formations using the process of hydraulic fracturing (fracking) requires the use of thousands of cubic meters of fluid. Hydraulic fracturing fluids are pumped under pressure into shale formations, fracturing the shale and releasing pockets of trapped gases. When the pressure in a natural gas...

Chemical Screening and Antibacterial Testing of Fungal Endophytes

Creator:: Pham, Andrew
Abstract:: Endophytes are bacteria or fungi that live within a host plant. The plant host provides a home for endophytes, and in return endophytes produce primary and secondary metabolites, of which many of the secondary metabolites possess biological activities. When microorganisms are grown under various media conditions, they produce different natural...

Abstract:: The North American host of the introduced Asian isopod parasite, Orthione griffenis, is the burrowing Blue Mud Shrimp, Upogebia pugettensis. The shrimp are the predominant species in the Yaquina Bay estuary intertidal mudflats, and are essential ecosystem engineers. The parasite effectively castrates the shrimp host without causing mortality which allows...

Adjuvant vitamin E and ovarian cancer

Creator:: Hartman, Alysha E.
Abstract:: Cisplatin (CDDP) is a highly active platinum-containing chemotherapeutic agent for use against solid tumors, including ovarian. However, like most antitumor agents, CDDP use is accompanied by non-tumor tissue toxicities leading to unwanted side effects, including neuropathy. To date, the mechanism(s) for these side effects are undefined. However, the clinical features...
