  • Development of a Boiling Surface Effectiveness Parameter by Modeling and Quantifying the Net Coolant Flow Rate

    Creator:
    Harrison, Matt
    Abstract:
    Boiling dynamics and related heat transfer mechanisms have been widely studied for several decades. During that time, incredible progress has been made on quantifying bubble departure phenomena including growth rate, departure frequency, associated natural and forced convection, and radiation additions to the overall heat transfer rate. With this, the thermal...

  • Tracking of Melt Pool Motion Using Numerical Analysis of Laser Powder Bed Fusion

    Creator:
    Cox, Bryce
    Abstract:
    Laser Powder Bed Fusion (LPBF) is a process commonly used to create additively manufactured metal parts. The flexibility and complexity allowed by the LPBF process provides opportunity for significant advancement in multiple industries as parts can be customized in shape and function for specific needs. These benefits can be compounded...

  • Evidence of a trophic cascade among wolves, elk, and aspen in Yellowstone National Park, USA

    Creator:
    Halofsky, Joshua S.
    Abstract:
    According to general top-down trophic theory, in the presence of carnivores, herbivore behavior and/or densities could change and result in an overall decrease in herbivory on plant communities. In this dissertation, I examined the potential relationship between gray wolf (Canis lupus) presence and absence on elk (Cervus elaphus) herbivory of...

  • Local Accessibility of Objective, Classical Reality

    Creator:
    Kincaid, Joshua J.
    Abstract:
    The fact that measuring a quantum system reduces it to apparently classical behavior, eliminating the interference patterns that are a hallmark of quantumness, cries out for an explanation. That explanation has been provided by the recognition of decoherence,whereby the interference is destroyed by the very interaction that acquires information.We begin...

  • Phylogeny of the "Chaoboriform" genera

    Creator:
    Ogawa, Joshua R.
    Abstract:
    The phantom midges (Diptera: Chaoboridae) are a relatively small fly family composed of 50 extant species in six genera. Larvae are of interest to limnologists and ecologists because of their tolerance to toxicants, predatory avoidance strategies, and the role chaoborids play in zooplankton community dynamics. Relative to mosquitoes, systematists have...

  • Total synthesis of (-)-7-epicylindrospermopsin

    Creator:
    Hansen, Joshua D.
    Abstract:
    The first asymmetric synthesis of (-)-7-epicylindrospermopsin via intramolecular nitrone cycloaddition is described. The synthesis utilized a convergent approach to prepare the cycloaddition precursor 176, which was assembled by condensation of hydroxylamine 175 with aldehyde 145. Hydroxylamine 175 was synthesized from ethylene glycol (166) in seven steps. Aldehyde 145 was completed...

  • An Interdisciplinary approach towards understanding late Pleistocene ice sheet change

    Creator:
    Cuzzone, Joshua K.
    Abstract:
    The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various techniques in geochemistry, climate modeling, and ice-sheet modeling to address ice- sheet response to climate and the attendant interactions...

  • Analysis of secondary structures in nucleic acid binding proteins and nuclear magnetic resonance investigation of helix propagation and residual motions in proteins

    Creator:
    Hicks, Joshua M.
    Abstract:
    This thesis involves analyses of 3₂-helices, a-helices and of the change in residual entropy of a protein upon chemical modification. Part of the long-term goal of understanding the formation, function and stability of proteins requires that all conformations be accurately assigned and structurally understood. By a statistical analysis of 258...

  • Substitution Effects on the Structure and Electronic Behavior of Ternary Precious Metal Oxides

    Creator:
    Flynn, Joshua
    Abstract:
    Due to the high cost of precursor materials, complex oxides of 4d and 5d transition metals are under-studied compared to their 3d counterparts. Recent studies have shown that oxides containing heavier transition metals can exhibit exotic electronic states due to presence of strong spin-orbit coupling. The goal of this dissertation...

  • Societal Responses to Using Genetic Engineering for Mitigating Chestnut Blight and Restoring American Chestnut Trees

    Creator:
    Petit, Joshua D.
    Abstract:
    Forests face health threats from pests and diseases (e.g., mountain pine beetle, emerald ash borer, chestnut blight [CB], Swiss needle cast), and other issues such as climate change. Interventions such as genetic engineering (GE) have shown promise for mitigating some of these threats. CB, for example, has impacted most American...
