Wood-Rotting Fungal Pigments as Colorant Coatings on Oil-Based Textile Dyes: A Detailed View of the Interaction between Fungal Pigments and Some Commercial Fabrics

Creator:: Palomino Agurto, Mardonio
Abstract:: Natural dyes have been used to color textiles for centuries, but with the shift to mass production, the use of synthetic dyes has increased due to their lower cost and easy manufacturing volume. However, synthetic dyes (such as disperse blue dyes 106 and 124) have been reported to cause skin...

Vulnerability and adaptation of Pacific Northwest shellfisheries to ocean acidification

Creator:: Katz, Brian G.
Abstract:: The purpose of this study was to understand the vulnerability and adaptive capacity of shellfish stakeholders in the Pacific Northwest who are adapting to ocean acidification (OA). This study developed a geovisualization tool of existing environmental data for assessing species-specific risk profiles to OA (based on their exposure and sensitivity),...

The Processing and Microstructures of 309L Stainless Steel Clad onto Carbon Steel with Wire-fed Directed Energy Deposition

Creator:: Bozeman, Scott C.
Abstract:: Directed energy deposition and laser cladding technologies are suitable advanced manufacturing techniques for applying corrosion-resistant claddings to large carbon steel components. In this work, we clad 309L stainless steel wire onto carbon steel substrates and examine the effects of cladding parameters (laser power and travel speed) on metallurgical bonding, composition,...

The Effects of Structure and Volcanic Stratigraphy on Groundwater and Surface Water Flow: the Hat Creek basin Case Study, California, USA

Creator:: Marcelli, Marina F.
Abstract:: Hydrogeologic systems in the southern Cascade Range develop in volcanic rocks where volcanic morphology, stratigraphy, extensional structures and attendant basin geometry play a central role in groundwater-flow paths, groundwater/surface-water interactions, and spring discharge locations. High-volume springs (> 3 m3/s) flow from young (< 1 Ma) volcanic rocks in the Hat...

The Development of a Hybrid Particle-in-Cell Simulation Code in C++ for the Modeling of the SPT-70 Hall Thruster

Creator:: Myers, Conner J.
Abstract:: In order to support the growing satellite propulsion industry, a hybrid Particle-In-Cell (PIC) simulation with fluid treatment of electrons and neutral particles was developed to model the SPT-70 Hall thruster. The 2D, C++ code assumes azimuthal symmetry and a uniform magnetic field in the radial direction with the simulation domain...

The Cosmetic Stay-Green Trait in Snap Bean and the Event Cascade that Reduces Seed Germination and Emergence

Creator:: Cirak, Melike
Abstract:: The persistent color (pc) trait in snap bean (Phaseolus vulgaris L.) belongs to a member of the cosmetic stay-green gene family. It is considered very desirable by snap bean breeders for its impacts on pod quality. Persistent color imparts a uniform dark-green color to pods and expresses in seeds as...

Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

Creator:: Caplan, Daniel L.
Abstract:: In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...

Synthesis and Characterization of an Ultrafine-Grained Aluminum-Copper System through High-Pressure Torsion

Creator:: Liang, Guangyuan
Abstract:: Aluminum and copper and their alloys have been widely used due to relatively high strength-to-weight ratios compared with conventional steels. Processing of these alloys is typically conducted at high temperatures over extended time periods. High-pressure torsion (HPT) is a promising processing technique for introducing significant grain refinement leading to excellent...

Survey of isotope ratios in the near coastal outflow of the Columbia River

Creator:: Dolan-Caret, Amari
Abstract:: This report details ocean water salinity and stable isotope measurements (deuterium (D) and 18O) in water collected from April 17 2018 to April 21 2018 in the coastal waters of Oregon, USA. Measurements were made from surface, ship flow-through, and CTD rosette bottle samples collected as part of a student-led...

Small Scale Modeling of a Broad Area Detector Network Array

Creator:: Johnson, Patrick M.
Abstract:: Nuclear material monitoring systems have long been established at ports of entry. However, there are no standard systems for monitoring points of interest within the country. Therefore, the use of a network of radiation sensors deployed throughout an area of interest is being investigated within this thesis. Before full scale...
