Determination of marine migratory behavior and its relationship to selected physical traits for least cisco (Coregonus sardinella) of the western Arctic coastal plain, Alaska

Creator:: Seigle, John C.
Abstract:: With increased resource development on the western Arctic coastal plain of Alaska (especially within the oil extraction industry) it is important to understand the basic life history attributes of whitefish stocks in the region in order to ensure appropriate management. These fish are a crucial part of subsistence harvests for...

Early Oligocene intrusions in the central Coast Range of Oregon : petrography, geochemistry, geochronology and implications for the Tertiary magmatic evolution of the Cascadia forearc

Creator:: Oxford, Jeremiah
Abstract:: The Early Oligocene Oregon Coast Range Intrusions (OCRI) consist of gabbroic rocks and lesser alkalic intrusive bodies that were emplaced in marine sedimentary units and volcanic sequences within a Tertiary Cascadia forearc basin. The alkalic intrusions include nepheline syenite, camptonite, and alkaline basalt. The gabbros occur as dikes and differentiated...

Mineralogy and geochemistry of copper deposits of the Lights Creek Stock, California : an assessment of porphyry versus iron-oxide copper origin

Creator:: Stephens, Abigail E.
Abstract:: The Lights Creek Stock is an 18 square kilometer copper-bearing granitoid intrusion within the Plumas Copper Belt in the northern California Sierra Nevada. Engels Mine, Superior Mine, and Moonlight Valley represent the main copper-mineralization in the Lights Creek district and small prospects include the Ruby Mine, and Moonlight Creek. The...

Helium isotope variations in peridotite, gabbro and basalt from the Kane Oceanic Core Complex

Creator:: Konrad, Kevin
Abstract:: The Kane Oceanic Core Complex (OCC) is a valuable window into crustal architecture and chemical composition of the lithosphere beneath a slow-spreading ocean ridge. A suite of > 30 samples (comprised of whole rocks, mineral separates and basalt glasses) has been analyzed for ³He/⁴He isotope ratios and He concentrations. Gas...

The genesis of the San Vicente lead zinc rhythmite deposit, Peru : a petrologic, geochemical, and sulfur isotope study

Creator:: Schütfort, Erwin G.
Abstract:: The San Vicente zinc lead deposit is located in the Eastern Andes of Central Peru. The deposit is an epigenetic Mississippi Valley-type deposit based on stratigraphic, geologic, petrographic, and geochemical evidence. The dolomite host rocks of the Pucara Group are of Triassic-Jurassic age. The source of metals are red sandstones...

Wheeled Mobility Devices Performance and Passive Securement Systems

Creator:: Mather, Andrea
Abstract:: Wheeled mobility devices (WhMD) pose unique safety risks to users while riding public transportation. Unsecured or improperly secured WhMDs create safety concerns for other transit riders and operators. Tests using accelerometers and visual observations were conducted to understand how WhMD orientation and securement in articulated buses, streetcars, and light rail...

A study of the ergonomics of emergency stop pushbuttons

Creator:: Zárate, Patricia B.
Abstract:: Emergency stop controls are essential parts of industrial machinery because they are designed to stop the operation in case of emergencies without risks to operators, equipment, products, or facilities. Current guidelines for emergency stop controls have been formulated based on experience but not on empirical studies. The main objectives of...

Electronic device and nanolaminate application of amorphous metal thin films

Creator:: Cowell, E. William, III
Abstract:: The objective of this dissertation is to develop amorphous metal thin films (AMTFs) for two-terminal electrical device and nanolaminate applications. Two AMTFs, ZrCuAlNi and TiAl, are investigated in both two-terminal electrical device and nanolaminate applications. Material properties including composition, atomic order, surface morphology, surface potential, and electrical resistivity are explored....

Atomic solid state energy scale applied to novel thin-film solar absorbers

Creator:: Pelatt, Brian D.
Abstract:: The atomic solid state energy (SSE) scale is introduced as a tool for inorganic materials design. The SSE scale is obtained by assessing an average electron affinity (EA) (for a cation) or an average ionization potential (IP) (for an anion) for each atom using data from compounds having that specific...

Volcanology and petrology of the Rattlesnake Ash-Flow Tuff, eastern Oregon

Creator:: Streck, Martin J.
Abstract:: The Rattlesnake Ash-Flow Tuff erupted 7.05±0.01 Ma from the western Harney Basin, southeastern Oregon. The location of the vent area is inferred based on vent-ward increases in size of pumices, in degree of welding, and in degree of post-emplacement crystallization. Today's outcrops cover 9000 km2 and estimated original outcrop coverage...
