  • Vertebral elemental markers in elasmobranchs : potential for reconstructing environmental history and population structure

    Creator:
    Smith, Wade D.
    Abstract:
    Differences in the chemical composition of calcified structures can be used to reveal natal origins, connectivity, metapopulation structure, and reconstruct the environmental history or movement patterns of many marine organisms. Sharks, skates, and rays (elasmobranchs) lack the calcified structures, known as otoliths, that are typically used for geochemical studies of...

  • Application of sandwich structure analysis in predicting critical flow velocity for a laminated flat plate

    Creator:
    Jensen, Philip
    Abstract:
    The Oregon State University (OSU), Hydro Mechanical Fuel test Facility (HMFTF) is designed to hydro-mechanically test prototypical plate type fuel. OSU's fuel test program is a part of the Global Threat Reduction Initiative (GTRI), formerly known as the Reduced Enrichment for Research and Test Reactor program. One of the GTRI's...

  • An Approach to Modeling Fuel Plate Deformations in Fluid-Structure Interactions

    Creator:
    Howard, Trevor
    Abstract:
    As computational power increases, so does the desire to use fluid-structure interaction (FSI) software to design complex systems and components such as fuel plates. Presently, an effort is underway to support the design and qualification of a new nuclear fuel material which is intended for applications in select, plate-type, research...

  • On the road to sustainability : Assessing Belize's fisheries management reform using a multiscalar governance approach

    Creator:
    Wade, Eric A.
    Abstract:
    The management of small-scale fisheries (SSF) around the world is facing increasing demands for reformation given ecological, social, and economic vulnerabilities. The governance of SSF is particularly important to foster the sustainability of these systems given that it combines regulatory instruments, interactive participation of diverse stakeholders, and the guiding values...

  • Predicting mechanical instability of a cylindrical plate under axial flow conditions

    Creator:
    Marcum, Wade R.
    Abstract:
    Five U.S. high performance research reactors (HPRRs) are currently part of an international nonproliferation program with the objective of ultimately converting their highly enriched uranium (HEU) fuel to a new high density, low enriched uranium (LEU) fuel while still maintaining their reactor kinetic and thermal hydraulic performance. A uranium-molybdenum (U-Mo)...

  • Decision-making in the Face of Uncertainty: Examining the Interplay between Social Relations and Loss Aversion in Small-Scale Fishing Communities in Jamaica

    Creator:
    Wade, Eric A.
    Abstract:
    Decision-making is a highly complex process influenced by the values, attitudes, and cognitive biases of the decision-maker. The classical model of decision-making fails to fully incorporate how decisions are made in situations of uncertainty, where having complete knowledge of all possible outcomes and alternatives is not always possible. In highly...

  • Cultural competency in associate degree nursing education : a skills approach

    Creator:
    Wade, Jennifer L.
    Abstract:
    The purpose of this study was to determine whether a course in cultural competency would impact associate degree nursing students' perceptions of their abilities to provide care to culturally diverse clients. Ethnographic interviews with nursing faculty, graduates and students were utilized in course development. The cultural competency course was evaluated...

  • Blowdown transient critical heat flux

    Creator:
    Moussaoui, Musa A.
    Abstract:
    Occurring in the most challenging nuclear power plant accidents, transient critical heat flux (CHF) is the primary phenomenon that drives peak cladding temperature and ultimately fuel failure. It is unclear whether the use of steady-state CHF correlations can accurately predict the gross thermal-hydraulic perturbations of a blowdown in a large...

    Abstract:
    In the most challenging nuclear power plant accidents, transient critical heat flux (CHF) is a primary phenomenon that drives peak cladding temperature and ultimately fuel failure. It is not yet determined whether the use of steady-state CHF methods can accurately predict transient CHF under the conditions of a blowdown due...

  • A Computational Fluid Dynamic Study on Flow Induced Vibration in Helically Wire Wrapped Rods Under Axial Turbulent Flow

    Creator:
    Winkle, Tristan
    Abstract:
    Vibration of nuclear fuel rods is an area of significance for the long-term safe operation of any nuclear power plant. One mechanism of vibration, flow induced vibration (FIV), must be quantified when designing a new core, such as a sodium fast reactor which employs helically-wrapped wire spacers. Experimental work undertaken...
