Surface Characterization of Engineered Biomaterials

Creator:: Faase, Ryan A.
Abstract:: The work presented in this dissertation highlights the various techniques available to characterize the increasingly complex surfaces of engineered biomaterials. The methods used range from the simple measurement of a contact angle with a smartphone to a complex synchrotron technique like near edge x-ray absorption fine structure (NEXAFS) spectroscopy to...

New development of beta-chitosan from jumbo squid pens (Dosidicus gigas) and its structural, physicochemical, and biological properties, New development of β-chitosan from jumbo squid pens (Dosidicus gigas) and its structural, physicochemical, and biological properties

Creator:: Jung, Jooyeoun
Abstract:: β-chitin/chitosan extracted from newly utilized jumbo squid (Dosidicus gigas) pens were investigated in respect to their physicochemical properties, polymeric structures, deacetylation and depolymerization characteristics, and antioxidant and antibacterial activities. These functional properties were further compared with α-chitin/chitosan prepared from shrimp shells. Due to the low mineral content (< 1%) and...

Surface Water - Groundwater Interactions in Clayey Pasture fields in the WIllamette Valley

Creator:: Gómez, Daniel G.
Abstract:: As the western United States continues to experience prolonged drought that is extending water deficits and threatening ecosystem resilience and socioeconomic systems, it will be vital to understand the relationship between water use and transport for proper water resource management. This is especially important to the agricultural areas of the...

Multiple-resistant Italian ryegrass (Lolium perenne spp. multiflorum) populations in Oregon

Creator:: Liu, Mingyang
Abstract:: Italian ryegrass (Lolium perenne spp. multiflorum) is a common weed management problem in turfgrasses, cereals and non-crop areas in the United States. In Oregon, the number of populations with multiple-resistance continues to increase. To manage these resistant populations, the resistance patterns must be determined. In this study, five Italian ryegrass...

Suppression of Met signaling by the green tea polyphenol (-)-epigallocatechin-3-gallate (EGCG)

Creator:: Larsen, Christine A.
Abstract:: Met is a prognostic indicator of colorectal cancer patient survival. Therapies that target Met may therefore have beneficial outcomes in the clinic. Recently, EGCG was reported to suppress Met activation, although the mechanisms were not elucidated. HCT116 and HT29 human colon cancer cells were used to examine the relationships between...

Proportional integral derivative control of an oil-heated fractal-like branching microchannel desorber

Creator:: Davis, Keith R.
Abstract:: A PID controller was designed to control the performance of an oil-heated fractal-like branching microchannel desorber for use in an ammonia-absorption refrigeration system. Both the amount and concentration of ammonia refrigerant generated at the desorber can be controlled by choosing the rectified circulation ratio as the controlled variable in a...

All in a DNA's work : conservation genetics and monitoring of the New Zealand endemic Maui's and Hector's dolphins

Creator:: Hamner, Rebecca Marie
Abstract:: The critically endangered Maui's dolphin (Cephalorhynchus hectori maui) and the endangered Hector's dolphin (C. h. hectori) are endemic to the coastal waters of New Zealand, where their primary threat is fisheries-related mortality. The Maui's dolphin is among the most critically endangered cetaceans in the world, with its remnant population primarily...

Peak reconstruction of single particle mass spectrometry transient signals to recapture ion count and improve SNM ratio measurements

Creator:: Mannino, Mitchell
Abstract:: Quick and accurate measurements of nanoparticles have important applications in biology, environmental and non-proliferation areas. Calculation of isotopic ratios, particularly in special nuclear materials, has relied on integration of nanoparticle counts and limited the capability of counting minor isotopes. Rapid transient detection method of nanoparticles has demonstrated the effectiveness of...

Role of myosin heavy chain polymorphism in differential susceptibility of muscle fibers to eccentric contraction

Creator:: Choi, Seung Jun
Abstract:: Relationships between myosin heavy chain (MHC) isoform content and eccentric-induced damage were investigated in chemically skinned muscle fiber segments. Fibers were subjected to an eccentric contraction standardized for strain magnitude (0.25 fiber length) and velocity (0.50 maximal shortening velocity). Fiber MHC isoform content was identified by SDS-PAGE. Pre- to post-eccentric...

Semi-volatile fluorinated organic compounds in Asian and Pacific Northwestern U.S. air masses

Creator:: Piekarz, Arkadiusz M.
Abstract:: Current studies suggest that perfluorinated organic compounds, such as fluorotelomer alcohols (FtOHs) in the troposphere, may be precursors of perfluorocarboxylic acids and perfluorosulfonates in remote regions. Fluorinated organic compounds were investigated in archived extracts collected from remote locations in Okinawa, Japan (HSO) and Mount Bachelor, Oregon (MBO) during the springs...
