An autumn journey : time, place, and pattern in Henry David Thoreau's later work

Creator:: Dotterman, Anthony Matthew
Abstract:: This thesis situates a discussion of Thoreau's later natural history essays in the context of the author's other writings. Beginning with an examination of the writings of Thoreau's friend and mentor Ralph Waldo Emerson, this paper examines Thoreau's relation to and departure from Emerson's understanding of time, place, and pattern...

Interaction of recombinant factor VIII and the nonionic surfactant Tween 80 at interfaces

Creator:: Joshi, Omkar
Abstract:: The role of the nonionic surfactant Tween 80 on the behavior of the therapeutic recombinant protein Factor VIII (rFVIII) was investigated at solid/liquid and air/water interfaces. In order to provide a model system to compare results obtained for the complicated rFVIII-Tween system, a well-characterized globular protein lysozyme was used. The...

New Insights into Mantle Dynamics from Helium Isotopes and Argon Geochronology

Creator:: Konrad, Kevin
Abstract:: Earth’s mantle extends to nearly 3000 km depth, comprises >80 % of Earth’s total volume, and has the largest influence on the primordial and radiogenic heat budget. Despite its importance, the structure and composition of the mantle is still debated. There are three primary models for Earth’s mantle structure that...

Influence of supplement composition on utilization of low-quality, cool-season forages by beef cattle

Creator:: McGuire, Dustin L.
Abstract:: Two studies were conducted to evaluate the influence of supplement composition on intake and digestibility of a low-quality (< 6% CP), cool-season forage, as well as cow performance. Treatments included a non-supplemented control (CON), corn (approximately 8% CP), corn and urea (LU = corn + 0.09 mg/kg BW urea, approximately...

Elution of adsorbed proteins at hydrophobic and hydrophilic surfaces by dodecyltrimethylammonium bromide and sodium dodecyls sulfate

Creator:: Vinaraphong, Pravina
Abstract:: Adsorption kinetic data recorded for α-lactalbumin, β-casein, β-lactoglobulin, bovine serum albumin and lysozyme at silianized silica surfaces of low and high hydrophobicity, along with a simple model for adsorption and surfactant-mediated elution of protein, were used to analyze the removal of each protein by sodium dodecylsulfate (SDS) and dodecyltrimethylammonium bromide...

The influence of cutting treatments on yield and quality of two alfalfa (Medicago sativa L.) varieties

Creator:: Contreras, David
Abstract:: A field experiment was conducted to study the influence of cutting treatments on the yield and quality of non-irrigated alfalfa in western Oregon. Spring clipping treatments included (1) not clipped, (2) clipped when 6 inches high and (3) clipped when 12 inches high. The hay harvest criteria were (1) near...

Generalized Preconditioning to Accelerate Simulations with Large Multiphase Chemical Kinetics Models

Creator:: Walker, Anthony S.
Abstract:: Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...

Estimating heterotrophic respiration at large scales: challenges, approaches, and next steps

Creator:: Bond-Lamberty, Ben, Epron, Daniel, Harden, Jennifer, Harmon, Mark E., Hoffman, Forrest, Kumar, Jitendra, David McGuire, Anthony, and Vargas, Rodrigo
Abstract:: Heterotrophic respiration (HR), the aerobic and anaerobic processes mineralizing organic matter, is a key carbon flux but one impossible to measure at scales significantly larger than small experimental plots. This impedes our ability to understand carbon and nutrient cycles, benchmark models, or reliably upscale point measurements. Given that a new...

Ectomycorrhizal populations on a chronosequence of disturbed areas in the central Cascades

Creator:: Meyer, Michele Marie
Abstract:: A greenhouse bioassay was used to investigate effects of natural and manmade disturbances on native ectomycorrhizal populations of Douglas-fir and western hemlock on a steep southeast slope in the west central Cascade Mountains. Total and mycorrhizal root tips were counted on seedlings grown in soils collected from (a) two 100+...

Molecular origins of surfactant-mediated stabilization of protein

Creator:: Lee, Hyo Jin
Abstract:: Nonionic surfactants are commonly used to stabilize proteins during upstream and downstream processing and drug formulation. Surfactants stabilize the proteins through two major mechanisms: (i) their preferential location at nearby interfaces, in this way precluding protein adsorption; and/or (ii) their association with protein into "complexes" that prevent proteins from interacting...
