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...

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...

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...

Experimental and numerical analysis of transport in saturated heterogeneous media

Creator:: Harrington, Stephanie J.
Abstract:: The conventional advection-dispersion equation cannot adequately describe all processes driving solute transport in heterogeneous systems. This dissertation focuses on the individual influences of both chemical (Chapter 2) and physical processes (Chapters 3 and 4) which affect solute transport. In Chapter 2 we analyzed uranium transport in natural sediment using the...

Factors associated with the implementation fidelity of a school-based social and character development program : findings from the Positive Action program, Hawai’i

Creator:: Beets, Michael W.
Abstract:: Implementation fidelity (dosage, adherence, quality of delivery, responsiveness, program differentiation) is the degree to which a program was carried out to its original intent. The following three studies examined the implementation fidelity of a school-based health promotion social and character development (SACD) program. The, Positive Action (PA) program was a...

The Modeling of Core-Wide Behavior of Pebble Bed Reactors Using Static and Dynamic Graphite Pebble Properties to Predict Core Performance and Safety Behaviors

Creator:: Cox, Jordan T.
Abstract:: The United States Department of Energy has identified the pebble-bed reactor as a high priority for US research with the end goal of licensing a pebble-bed reactor (PBR) for operation in the United States. Before this can be accomplished significant research must be done regarding the safety of the pebble-bed...

Micromixer assisted continuous flow synthesis of nanoparticles of binary compounds and their application

Creator:: Palanisamy, Barath
Abstract:: In this work, continuous synthesis routes for binary nanoparticles using advantages of microchannel mixing (low diffusion distances and higher mass transfer) and fast heating rates provided by ultrasound induced heating are investigated. In addition, the application of silica nanoparticles in anti-reflective coatings on glass and understanding the structure property-performance correlation...

Culture and Contexts of Intimate Partner Violence in Nigeria : The Role of Child Marriage, and Implications for Public Health and Population Growth

Creator:: Nwegbu, Somawina Chiazo
Abstract:: Intimate partner violence against women (IPVAW) and early marriage of female children are significant public health challenges in Nigeria. Previous research has shown a strong association between the two. Furthermore, both issues have severe implications for socioeconomic progress and present barriers to the realization of the Sustainable Development Goals (SDGs)....
