  • Approaches for Characterizing Plant Physiological Responses to Environmental Stress

    Creator:
    Marias, Danielle E.
    Abstract:
    It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...

  • Assessing Managed Aquifer Recharge Potential: Regional to Local Evaluation

    Creator:
    Gibson, Maria
    Abstract:
    Although surface water constitutes less than 1.5% of freshwater supply, historical development of surface water sources continues to mark the landscape. However, over- exploitation of groundwater is now at its highest, and 25% of the world’s 1.7 billion population live in water scare regions. As glaciers and snowpack disappear due...

  • Genesis of iron oxides in unsaturated porous media

    Creator:
    Grover, Deeksha
    Abstract:
    The kinetics of physical and chemical processes controlling the precipitation of iron oxide minerals in unsaturated media were investigated in this study. The characteristic morphology, mineralogy, and chemistry of iron oxides were also explored. Laboratory column experiments using fine and coarse grades of silica sand were conducted to compare the...

  • Hydrological consequences of two native shrubs in semi-arid Senegal : patterns, processes, concepts and methods

    Creator:
    Kizito, Fred
    Abstract:
    Water availability is a critical limiting element in semi-arid ecosystem productivity and presents particular challenges in Sahelian countries such as Senegal. The landscapes are characterized by the presence of two common semi-arid shrubs (Piliostigma reticulatum and Guiera senegalensis), both of which may be important hydraulic regulators in these water-limited ecosystems....

  • Physical processes that control droplet transport in rock fracture systems

    Creator:
    Hay, Katrina M.
    Abstract:
    Aquifer recharge is generally driven by fluids that move from the Earth’s surface to groundwater through the unsaturated zone, also known as the vadose zone. When the vadose zone is fractured, fluids, which may include contaminants, can move through the fracture network as well as the porous matrix. Such a...

  • An analysis of Maria Montessori’s theory of normalization in light of emerging research in self-regulation

    Creator:
    Lloyd, Kathleen M.
    Abstract:
    The regulation of behavior is a major issue in early childhood development, with important implications for children’s adaptive and maladaptive developmental outcomes. Emerging research suggests that the degree of successful self-regulation depends upon the efficiency of the child’s attentional system and that the ability to focus and sustain attention supports...

  • Interactions of Amphorophora agathonica Hottes with raspberry viruses and resistant red and black raspberry

    Creator:
    Lightle, Danielle
    Abstract:
    In recent years, red raspberry production in Washington and British Columbia has been severely limited by a newly emerged virus complex that causes symptoms of crumbly fruit. The complex is comprised of three viruses: Raspberry bushy dwarf virus (RBDV), Raspberry leaf mottle virus (RLMV) and Raspberry latent virus (RpLV). Both...

  • A Corpus Linguistic Analysis of Self-compassion and Postpartum Self-help Literature

    Creator:
    Watkins, Danielle L.
    Abstract:
    The self-help literature is full of texts on both self-compassion and postpartum depression. However, there has been minimal scientific exploration of the literature on these topics. As such, mental health researchers and practitioners have little sense of the psycholinguistic discourse contained in this literature. This study aimed to fill this...

  • Bio-Inspired Design of Vehicles that Operate in Complex Environments

    Creator:
    Jackson, Danielle M.
    Abstract:
    This dissertation focuses on defining underlying mechanisms to enable the bio-inspired design of aerodynamic and/or hydrodynamic vehicles that operate within complex environments. This dissertation introduces four overarching research gaps found in current bio-inspired design research and four corresponding approach questions that guide the framework of the presented research. This research...

  • Synthesis and Solution Characterization of Metal-Oxo Photoresist Precursors

    Creator:
    Hutchison, Danielle C.
    Abstract:
    Metal-oxo clusters can be described as soluble pieces of metal-oxide frameworks. Currently, metal-oxo clusters are being considered as solution-based precursors for extreme ultraviolet (EUV, 13.5 nm) photoresist materials, which are a crucial component in the fabrication of microelectronic devices. Two different photoresist precursor systems have been investigated – alkyltin clusters...
