Development of a progeny marker for steelhead

Creator:: Shippentower, Gene E.
Abstract:: This study was undertaken to determine if strontium chloride could be used to create a trans-generational otolith mark in steelhead (Oncorhynchus mykiss). I completed two strontium injection trials and a survey of juvenile steelhead from various steelhead hatcheries. The two trials measured Sr:Ca ratios in otoliths in response to injections...

Dynamics of a long-lived magmatic system as indicated by variations in amphibole composition and textures in dacites erupted over 11 M.y. at the Aucanquilcha Volcanic Cluster, Central Andes, Chile

Creator:: Giles, Denise E. L.
Abstract:: The Aucanquilcha Volcanic Cluster (AVC) is the erupted part of a magmatic system with a complex and long-lived history. The AVC lies at 21°S in the high Andes and is built on thick continental crust. The thick crust in the area combined with the prolonged magmatic activity make it an...

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...

Roles of gas and solid components in the direct nitridation of silicon

Creator:: Pavarajarn, Varong
Abstract:: The factors influencing the direct nitridation of silicon, including the effects of the native oxide layer covering the surface of silicon, the effects of hydrogen contained in the nitridation gas and the catalytic effects of metals added to the raw material silicon, were investigated, using a tubular flow reactor and...

Deep crustal and mantle inputs to North Sister Volcano, Oregon High Cascade Range

Creator:: Schmidt, Mariek E.
Abstract:: The Central Oregon High Cascade Range is an anomalously mafic segment of the Cascade Arc due to ongoing intra-arc extension, which allows most magmas to traverse the crust without stalling and evolving to more evolved compositions. North Sister, a composite volcano in this arc segment, has produced a seemingly monotonous...

Evolution of volcanism and hydrothermal activity in the Yanacocha Mining District, northern Perú

Creator:: Longo, Anthony A.
Abstract:: The Yanacocha Mining District in northern Perú is considered the largest group of high-sulfidation style epithermal gold deposits in the world. District-scale geologic mapping coupled with detailed 40Ar/39Ar geochronology, geochemistry and petrography establish the volcanic history of the area and analyze the temporal and spatial evolution of volcanism, hypogene advanced...

Phase diagram, thermal stability, and high temperature oxidation of the ternary Cu-Ni-Fe system

Creator:: Gallino, Isabella
Abstract:: Due to the aluminum industry demands, a large effort has recently been devoted to the development of special alloys to be used as inert anodes for a newly designed aluminum reduction cell. The implementation of this new technology aims at the replacement of the graphite anodes that have been used...

Spatial and temporal scales of genetic change in two overfished rockfishes

Creator:: Gomez-Uchida, Daniel
Abstract:: Pacific rockfishes (genus Sebastes) have attracted wide scientific and public interest from an evolutionary, fishery and conservation standpoints. This dissertation addresses several hypotheses involving spatial and temporal scales of genetic change in two overfished rockfishes, darkblotched (S. crameri) and canary rockfish (S. pinniger), using statistical analyses of genetic variation within...

The design of a test environment and its use in verification of a scalable modular multiplication and exponentiation

Creator:: Khair, Elias
Abstract:: Information security is an important concern in today’s communication and business world. To achieve these security functions, cryptography is utilized. RSA and the Diffie Hellman key exchange are some examples of cryptography algorithms that use modular multiplication to compute modular exponentiations. Modular multiplication requires division operations which becomes very time...
