Prompt gamma neutron activation analysis of niobium for characterization of light interstitials

Creator:: Love, Ian J.
Abstract:: High purity niobium metal is used in the construction of superconducting radio frequency (SRF) cavities in superconducting particle accelerators, such as the Large Hadron Collider (LHC) at CERN or the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory. The usual method for characterizing the impurities in this niobium, the...

Incorporation of salmon derived nutrients into Oregon coastal streams and the role of physical habitat

Creator:: Shaff, Courtney D.
Abstract:: Stream restoration techniques in western Oregon and Washington include physical habitat restoration and more recently the addition of salmon carcasses to improve food availability for juvenile fish. Although both are common practices, few studies have examined the effects of carcass placement and the interaction of nutrient enrichment with physical habitat...

Investigating the Potential of Slow Release Nitrogen Fertilizer to Increase Agricultural Nitrogen Management Efficiency for Tall Fescue in the Southern Willamette Valley

Creator:: Derksen, Jacob Z.
Abstract:: Nitrogen (N) fertilizer application can promote nitrate leaching below the rooting zone and into groundwater drinking water sources in many agricultural settings. The proper management of N application can minimize non-point source nitrate pollution to groundwater. This study examines the potential for enhanced efficiency fertilizers, specifically urea treated with a...

Electron drift velocities in hydrogen and deuterium

Creator:: Tucker, Stevens Parrington
Abstract:: The drift velocity of electrons in pure hydrogen, in pure deuterium, and in mixtures thereof, has been observed at low pressures using the following pulse technique for these gases for the first time. Plane parallel electrodes of a known separation and immersed in the gas to be studied are connected...

On the measurability of change in Amazon vegetation from MODIS

Creator:: Hilker, Thomas, Lyapustin, Alexei I., Hall, Forrest G., Myneni, Ranga, Knyazikhin, Yuri, Wang, Yujie, Tucker, Compton J., and Sellers, Piers J.
Abstract:: The Amazon rainforest is a critical hotspot for bio-diversity, and plays an essential role in global carbon, water and energy fluxes and the earth's climate. Our ability to project the role of vegetation carbon feedbacks on future climate critically depends upon our understanding of this tropical ecosystem, its tolerance to...

Remote sensing of tropical ecosystems: Atmospheric correction and cloud masking matter

Creator:: Hilker, Thomas, Lyapustin, Alexei I., Tucker, Compton J., Sellers, Piers J., Hall, Forrest G., and Wang, Yujie
Abstract:: Tropical rainforests are significant contributors to the global cycles of energy, water and carbon. As a result, monitoring of the vegetation status over regions such as Amazônia has been a long standing interest of Earth scientists trying to determine the effect of climate change and anthropogenic disturbance on the tropical...

Investigation of Thermal Degradation in Structural Alloys for Nuclear Power Systems

Creator:: Teng, Fei
Abstract:: The thermal degradation of structural materials is considered to be a key factor for evaluating the lifetime of current nuclear power plants. Ni-based and Fe-based alloys, such as 690, 625, 304, and 316, are widely used in nuclear industry as structural components due to the extraordinary corrosion resistance and mechanical...

Role of Stoichiometry on Ordering in Ni-Cr Alloys

Creator:: Teng, Fei
Abstract:: Mechanical property degradation due to isothermal ageing is of potential concern for alloys based on the Ni-Cr binary system (e.g., Inconel 690, 625), particularly in nuclear power applications where component lifetimes can exceed 40 years. In the present research, the disorder-order phase transformation, which is the primary mechanism of ageing,...

Microstructural Characterization of Porosity in U-Mo Low Enriched Uranium Plate Fuel

Creator:: Westman, Bjorn E.
Abstract:: New low enriched uranium (LEU) fuels are being developed for replacement of high enriched uranium (HEU) fuels in high power research reactors. U-Mo LEU plate fuels have been identified as a candidate for replacement of current HEU fuels. However, U-Mo fuels tend to exhibit accelerated swelling typically at fission densities...
