Soil surface CO2 efflux across the climatic gradient of the Oregon Transect for Terrestrial Ecological Research (OTTER)

Creator:: Martin, Mark A.
Abstract:: Soil CO2 efflux is a major contributor of CO2 to the atmosphere. The rate that CO2 is respired out of the soil is called the soil flux (Fs). Many variables alter Fs. These variables differ drastically in the variety of ecosystems found on the earth. It is important to understand...

Spatial and temporal variations in respiration rates and hypoxia on the Oregon shelf

Creator:: Wolf, Megan J.
Abstract:: Inner shelf hypoxia has occurred along the Oregon coast between the latitudes 44ºN and 45ºN since 2002 with increasing duration and intensity, posing a threat to marine life. The objective of this research was to determine whether variation in respiration rate explains spatial and temporal variation in hypoxia. Dissolved oxygen...

Exploring phylogeny of Rhodococcus fascians isolates using 16S ribosomal DNA sequence analysis

Creator:: Sandberg, Eva Song
Abstract:: Rhodococcus fascians is a Gram-positive, pleiomorphic actinomycete that causes leafy gall formation in a wide range of plant hosts. This particular phytopathogen has been a focus of research at the Oregon State University Plant Clinic, a diagnostic laboratory. Phylogeny of R. fascians isolates obtained from Plant Clinic submissions was determined...

Patterns of age and growth in young-of-year rockfish, sebastes spp., along the Oregon coast

Creator:: Young, Thomas
Abstract:: Rockfish of the genus Sebastes are important components of Oregon reef communities. I examined patterns of age and growth in young-of-year rockfish across two nested spatial scales – local and regional – along the Oregon coast. Using otolith microstructural examination, I examined the relative importance of local versus regional factors...

Investigating the Role of the MutLα Endonuclease

Creator:: Mankaney, Gautam Naresh
Abstract:: Lynch individuals have a predisposition to developing colorectal and other cancers due to inherited defects in their mismatch repair (MMR) system. Although mutations in MMR have been directly implicated in Lynch Syndrome, the precise mechanism(s) of MMR functions have yet to be elucidated. One essential complex, MutL (a dimer of...

High Resolution Spectroscopy of Bicyclo[1.1.1]pentane

Creator:: Martin, Matthew A.
Abstract:: The strained carbon ring, bicyclo[1.1.1]pentane, was synthesized by a reaction between 1-(phenylsulfanyl)bicyclo[1.1.1]pentane, prepared from propellane, and Raney nickel. Infrared spectra were recorded at a resolution of 0.0015 cm-1, a resolution significantly better than previous measurements, 0.06 cm-1. A single fundamental band was analyzed to determine the ground state and excited...

Sperm depletion and sperm competition in the red-sided garter snake, Thamnophis sirtalis parietalis

Creator:: Kerns, Amelia R.
Abstract:: Sperm competition is the post-copulatory analog of male-male combat, wherein sperm from more than one male coincide in a female’s reproductive tract and compete with one another for fertilization of a limited number of ova. Post-copulatory sexual selection, such as sperm competition, can be a powerful driving force for the...

Optical Characterization of Transparent Conductive Thin Films

Creator:: Tucker, Derek A.
Abstract:: The optical characterization of transparent conductive thin films is demonstrated. The basics of transparency and conductivity, as they relate to transparent conductor research, are explained. A functional model of the reflectance and transmittance of a sample film, including interference fringes, is derived from the Fresnel electric field amplitude coefficients. The...

Crossing cultural barriers : an analysis of sex education practices in the United States and Mexico

Creator:: Gaudenti, Dawn A.
Abstract:: Adolescents are faced with many life changing decisions as they prepare for adulthood. The choice to engage in sexual activity is among the most difficult of these decisions. Risks, such as unplanned pregnancy, sexually transmitted infections (STIs), and other physical complications associated with early onset sexual activity are a harsh...

Room Temperature Seebeck Measurements on CuSc1-xMgxO2+y Transparent Conductive Thin Films

Creator:: Easley, Dara L.
Abstract:: A series of seven magnesium-doped copper scandium oxide films were made by radio frequency sputtering, and intercalated at various oxygen pressures to create different oxygen concentrations in each film. The objectives of this study were to verify the p-type nature of these transparent conductive thin films, to determine the correlation...
