Organic Phase Inter-Ligand and Metal-Ligand Speciation in TALSPEAK and ALSEP Solvent Extraction Systems

Creator:: Gullekson, Brian J.
Abstract:: Partitioning of trivalent actinides (in particular, americium and curium) from the fission produced light lanthanides is a major concern of used nuclear fuel reprocessing for the purposes of waste disposal. Several solvent extraction processes have been developed to address these chemically difficult separations. The historically employed TALSPEAK Process utilizes di-2-ethylhexyl...

Synthesis and testing of a novel soft donor organic extractant molecule for targeted soft metal extraction from aqueous phases

Creator:: Gullekson, Brian J.
Abstract:: Spent nuclear fuel (SNF) resultant from the generation of nuclear power is a chemically and radiologically diverse system which is advantageous to chemically process prior to geologic disposal. Hydrometallurgy is the primary technology for chemical processing for light water reactor spent fuels, where spent fuel is dissolved in an acid...

Vacuum Testing of a Small Radioisotope Thermoelectric Generator

Creator:: Mieloszyk, Alexander J.
Abstract:: Radioisotope Power Systems (RPS’s) are a key element to NASA’s deep space exploration programs. As NASA looks towards new generations of smaller, modular spacecraft, appropriately smaller RPS’s will be needed. The Single General Purpose Heat Source Radioisotope Thermoelectric Generator (S-GPHS-RTG) has been developed to fill this role. The S-GPHS-RTG will...

Development and comparison of stand-level bucking optimization methods

Creator:: Laroze, André J.
Abstract:: Heuristics based on Monte-Carlo Integer Programming (MCIP) and Tabu Search (TS) techniques were developed for generating easily implementable bucking rules that are applicable to entire stands (as opposed to individual stem classes), and for selecting the rule-set that provides the best feasible solution (given log prices and market constraints). A...

Importance of timber-related revenues to local governments in Oregon and the effects of forests in Oregon on property tax rates

Creator:: Hackworth, Kevin
Abstract:: Local governments in Oregon receive money from the forestry sector in a number of ways. This paper briefly describes public and private forestry sector sources and the relative importance of their payments to five forms of local governments by county for fiscal year 1982-83 to 1985-86. An analysis of the...

Federal forest revenue-sharing in coastal Oregon : an assessment of historical and future tax equivalence

Creator:: Powell, Leslie A. (Leslie Ann)
Abstract:: Public land ownership withdraws property from the tax base of local property tax districts. Publicly-managed lands occupy approximately 17.5 million acres of forested lands in Oregon (inclusive of federal, state, and county ownership). To compensate local taxing districts for foregone property tax collections, Congress enacted a series of federal revenue-sharing...

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...

Jerking behavior among phytoseiid mite species (Acari: Phytoseiidae)

Creator:: Blackwood, J. Scott
Abstract:: Jerking, which we defined as a pronounced and often repeated lunging of the entire body, was studied in larvae among seven species of phytoseiid mites, and in the nymphal stages of Neoseiulus fallacis (Garman). This behavior was observed in all active immature stages of N. fallacis, and in larvae of...

Achilles Assistance Device as a Passive Ankle Foot Orthosis for Achilles Tendon Injuries

Creator:: Gonnerman, Evan J.
Abstract:: An Achilles tendon injury can be devastating. Surgical methods to bring the muscle to full strength are not always available. Proposed is an ankle foot orthosis (AFO) that is entirely passive (does not add energy to the system) and uses the mechanical advantages provided by the walking gait of a...

Evaluation of total hip arthroplasty research in the US and Europe

Creator:: Simmons, Marcy J.
Abstract:: Background: Hip replacements are considered routine operations which improve the quality of life in patients by reducing pain and restoring function. There are many variations in prostheses with varying benefits and disadvantages. Methods: Literature from the United States and Europe was collected on total hip replacements between 2001 and the...
