  • A three-dimensional mapping of the ocean based on environmental data

    Creator:
    Wright, Dawn J.
    Abstract:
    The existence, sources, distribution, circulation, and physicochemical nature of macroscale oceanic water bodies have long been a focus of oceanographic inquiry. Building on that work, this paper describes an objectively derived and globally comprehensive set of 37 distinct volumetric region units, called ecological marine units (EMUs). They are constructed on...

  • Efficacy of Empirical Seed Zones: Pseudoroegneria Spicata Reproductive Phenology & Seedling Stage Traits

    Creator:
    Prive, Kathryn A.
    Abstract:
    Ecological restoration is needed to mitigate losses to biodiversity. Restoration success is enhanced through the use of native plant materials that are genetically diverse and locally adapted. Seed transfer zones have been developed to delineate geographic areas where native seed can be collected and distributed with reduced risk of maladaptation....

  • Real Time Temporal Spectroscopy for Characterizing Special Nuclear Material

    Creator:
    Mannino, Mitch
    Abstract:
    Characterizing special nuclear material (SNM) is critical for nuclear security and non-proliferation. Temporal spectroscopy is a novel and efficient method for characterizing relative material content of special nuclear material. Fission products produced by SNM after being irradiated by a thermal neutron beam can have different half-lives, but can contribute to...

  • The Evaluation of Cementitious Pore Solution Composition and Electrical Resistivity Using X-ray Fluorescence (XRF)

    Creator:
    Tsui Chang, Marisol
    Abstract:
    Interest in performance specifications has been growing in the civil and construction industry in the past decade. One major focus area has been on understanding how to prolong the service life of concrete structures, since repair and rehabilitation of existing infrastructure have cost many trillions of dollars. Deterioration mechanisms such...

  • Power Efficient Hybrid Architecture for High Resolution Analog-to-Digital Converters

    Creator:
    Zhang, Hui
    Abstract:
    Analog-to-digital converters (ADCs) are the key building block for sensor applications, such as wireless communications and digital electronics. These applications require ADCs to have medium to high accuracy (normally from 10-14 bits) and relatively low signal bandwidth (ranging from 100Hz-150kHz). Since these applications are often powered by batteries, high power...

  • Predicting the Relationships between High School Characteristics and High School Community College Enrollment Rate Using the Oregon Promise.

    Creator:
    Murray-Jensen, Julie
    Abstract:
    Background: Legislators, policy-makers, and leaders in higher education and within communities, are increasingly turning to place-based scholarships, or “promise programs”, to encourage college enrollment and address growing public concerns regarding college affordability. One such program, the Oregon Promise, was implemented across the state of Oregon in the fall of 2016....

  • Disputed Spaces : Concheras, Shrimp Aquaculture, and Conservation in the Mangrove Forests of Southern Esmeraldas, Ecuador

    Creator:
    Treviño Peña, Melva B.
    Abstract:
    The mangrove ecosystem has served as a life-support system to large populations of coastal dwellers in Ecuador for many generations. Diverse communities comprised of multi-racial and multi-ethnic groups have formed along the edge of the mangrove forests throughout the Ecuadorian coast. These groups self-identify as being part of an “ancestral”...

  • Application of Infrared Spectroscopy for Determination of Wood Natural Durability

    Creator:
    Lipeh, Shahlinney
    Abstract:
    Natural durability remains one of the most attractive characteristics of wood, and helps wood obtain a premium price. A worldwide shift towards the use of younger trees from intensively managed forests has created greater concerns about wood quality, especially the wood’s resistance to fungi and insects. Wood durability is assessed...
