  • Multicellular monolayer’s self-organization under external stimuli

    Creator:
    Li, Guanyu
    Abstract:
    Cell signaling under external stimulation is a critical mechanism that governs many biological processes such as cell proliferation, cell migration, and cell apoptosis, etc. For multicellular organisms, the ability to synchronize heterogeneous individual cellular responses through intercellular communication is crucial to maintain normal functionality. However, even though the biological pathways...

  • Becoming birds: community scientists, place, and critical socio-ecoliteracy

    Creator:
    Wicks, Teresa O.
    Abstract:
    Community science (also called citizen science) has become an increasingly popular data collection technique for scientists researching nature at a large scale. Many ecologists have also looked to community science as a method for educating the public about science. Over the past several decades, researchers have attempted to define an...

  • Calcium-oxalate in sites of contrasting nutrient status in the Coast Range of Oregon

    Creator:
    Dauer, Jenny M.
    Abstract:
    Calcium (Ca) is an essential macronutrient that is increasingly recognized as a biogeochemical factor that influences ecosystem structure and function. Progress in understanding the sustainability of ecosystem Ca supply has been hampered by a lack of information on the various forms and pools of Ca in forest ecosystems. In particular,...

  • Teacher argumentation in the secondary science classroom : images of two modes of scientific inquiry

    Creator:
    Gray, Ron E.
    Abstract:
    The purpose of this exploratory study was to examine scientific arguments constructed by secondary science teachers during instruction. The analysis focused on how arguments constructed by teachers differed based on the mode of inquiry underlying the topic. Specifically, how did the structure and content of arguments differ between experimentally and...

  • Artificial means of distinguishing smooth-line map unit boundaries : an examination of Oregon soil survey maps

    Creator:
    Sun, Yulin
    Abstract:
    Soil is a complex living system with high heterogeneity, which makes locating soil map boundaries a challenge. In traditional soil survey, the placement of soil map boundaries relies largely (at least initially) on identifying the soil-forming factors of biota and topographic relief through stereo aerial photo pairs. Future soil survey...

  • Molecular and cellular mechanisms of aromatic hydrocarbon axonopathy

    Creator:
    Kim, Min-Sun
    Abstract:
    Hydrocarbon solvents are widely used in the production of paints, adhesives, dyes, polymers, plastics, textiles, printing inks, agricultural products and pharmaceuticals. While the neuropathic potential of aliphatic solvents was shown in the 1970s, little is known about the neuropathic potential of aromatic solvents. The present study examines such solvents, 1,2-diethylbenzene...

  • Genome Organization in the Ectomycorrhizal Truffle Rhizopogon vesiculosus

    Creator:
    Lu, Dabao Sun
    Abstract:
    Rhizopogon vesiculosus is a common ectomycorrhizal (EM) symbiont of Pseudotusga menziesii (Douglas-fir) in the coast range of the Pacific Northwest. The species has been studied for its systematics, genet size, population structure, and competitive ability in several field and experimental studies. This thesis seeks to provide a more thorough characterization...

  • Broad Histogram Algorithm Comparison for the Square Well Fluid

    Creator:
    Simpson, Tanner T.
    Abstract:
    Thermodynamic properties of systems are often investigated computationally. Traditionally, thermal physics simulations are limited by their very small energy ranges and slow convergence. Broad histogram algorithms are a class of Monte Carlo algorithms that can explore an entire energy (and temperature) range in one thermal physics simulation: potentially saving months...

  • Jumping in with Both Feet: Exploring Factors that Shape Juvenile Amphibian Movement

    Creator:
    Bredeweg, Evan M.
    Abstract:
    Investigation into how animals move within the landscape is important for both understanding of ecological processes and conservation management. Animal movement is important in shaping life history transitions, demographics, individual fitness, and species distributions. However, as landscapes become increasingly affected by human activities, movement becomes important as species navigate landscapes...

  • Photostability of organic semiconductors : from bulk to nanoscales

    Creator:
    Quist, Nicole Arianne
    Abstract:
    Organic semiconductors have attracted considerable attention due to their applications in low-cost, solution-processable (opto)electronic devices. An important class of high-performance organic semiconductors is pentacene derivatives, which exhibit high charger carrier mobilities in field-effect transistors and ultrafast singlet fission in photovoltaic devices. These derivatives have served as benchmark materials for systematic...
