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...

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...

Enhancing social-emotional and character development for youths' success : a theoretical orientation and an evaluation using a cluster-randomized design

Creator:: Snyder, Frank J.
Abstract:: Interest in social-emotional and character development (SECD) programming has intensified in recent years. SECD-related programs often seek to enhance a variety of health-related outcomes by addressing multiple influences and embracing a comprehensive approach that includes youth, school personnel, families, and communities. Alongside a comprehensive approach arises the need for a...

Prey-stage preference in phytoseiid mites

Creator:: Blackwood, J. Scott
Abstract:: Knowledge of how individual organisms behave in their environment can provide a greater understanding of population dynamics. In a predator-prey system, the choices made by predators when foraging for prey are important aspects of behavior. Particularly in the case of a stage-structured prey population, how the predator selects prey stages...

Stags of the Sea or Hedgehogs of the Harbor? Inferring the Point of Sculpin Cranial Weaponry

Creator:: Buser, Thaddaeus J.
Abstract:: Animal weapons are thought to have evolved to compete for reproductive opportunities within a species. Across the diverse weapon-bearing taxa, several evolutionary trends have emerged: (1) increasing complexity and relative size across ontogeny, (2) sexual dimorphism, and (3) higher levels of random deviations from symmetry (i.e., fluctuating asymmetry) than non-weaponized...
