  • Are they what they eat? A stable GIT microbiome characterized in P. resecata

    Creator:
    Gustafson, Tarah N.
    Abstract:
    Intertidal herbivores, such as isopods, help regulate and contribute to nutrient cycling and organic carbon flow through the trophic levels in estuaries and coastal ecosystems. Though much is known about the microbiomes of macrophyte leaves that serve as the primary food source for isopods, and (to a lesser extent) the...

  • Site-Specific Modification of Glucose Proteins Enabling Precise Surface Orientation For Glucose Sensors

    Creator:
    Wolfenden, Nurhayati
    Abstract:
    An ideal labeling reaction between protein and surface should generate a protein-patterned surface with control over the orientation of the desired protein. Controlling orientation would generate a homogeneous, un-fouled protein surface and allow for maximum efficiency in regards to the activity, reactivity, and stability of the protein. In this research...

  • Numerical Effects on Timing System Pathways

    Creator:
    Steiner, Samantha K.
    Abstract:
    Studying human’s ability to estimate temporal durations could lead to a greater understanding of our cognitive abilities as well as the processes that underlie temporal estimation. It has been shown through previous research that time and number may be interconnected cognitively and that the magnitude of one may alter the...

  • Improving the Photostability and Recovery of Organic Semiconductors

    Creator:
    Tollefsen, Ryan J.
    Abstract:
    This work aims to broaden use of the organic semiconductor pentacene (Pn) by means of improving its oxidation and photodimerization stability. In particular, we study the photophysical properties of functionalized Pn derivatives with side groups R in amorphous thin film, referred to as Pn-R-F8 when fluorinated. Using the optics experiments...

  • Selection of an Orthogonal tRNA Synthetase for Trifluoromethyl-phenylalanine in Methanomethylophilus Alvus System

    Creator:
    Eyberg, Daniel R.
    Abstract:
    Genetic code expansion is a technology that allows for site-specific incorporation of noncanonical amino acids into recombinant proteins at amber stop codons using engineered translational machinery. The technology allows for expanded study into proteins, derived from the integration of novel chemical functions found in noncanonical amino acids, such as fluorescence,...

  • Characterizing the Interactome of Nitrotyrosine-Calmodulin using Genetic Code Expansion

    Creator:
    Kong, Garth L.
    Abstract:
    A specific tyrosine post-translational modification, called 3-nitro-tyrosine (nitroTyr), has been known to be present on an essential calcium signaling protein called calmodulin (CaM) during oxidative stress. While protein-bound 3-nitro-tyrosine has long been considered a biomarker of OS, it is also hypothesized to be a mechanism for protein signaling. However, purification...

  • Controlled Orientation of Engineered Carbonic Anhydrase on a Surface : A Model for Protein Immobilization for Biosensors and Biomaterials

    Creator:
    Brown, Wesley
    Abstract:
    Current protein immobilization techniques lack defined control over protein orientation. Protein orientation is important for making biosensors and biomaterials that are sensitive and efficient and can be crucial for designing some devices such as immunosensors or direct electron transferring biocells. A new method of protein immobilization is proposed that takes...

  • Effects of wildfire on soil hydraulic properties on hillslopes in southwestern Oregon

    Creator:
    Cole, Ryan
    Abstract:
    The purpose of this study was to investigate the effects of wildfire on soil hydraulic properties of forested hillslopes. The study site was located within the Stouts Creek wildfire, which burned approximately 10,705 ha of forest in southwestern Oregon in summer 2015. Three soil hydraulic properties (soil moisture, unsaturated hydraulic...

  • The Effects of Wildfire on Soil Hydraulic Properties in an Appalachian Hardwood Forest

    Creator:
    Ruud, Danica R.
    Abstract:
    Wildfires can affect soil physical properties, resulting in changes in infiltration, hillslope runoff, groundwater recharge, and sediment and dissolved nutrients to streams. In November 2016, the Chimney Tops 2 Fire burned 4,617 ha of Appalachian hardwood forest in eastern Tennessee. A portion of the fire burned through a National Ecological...

  • The Genetic Diversity of Salukis in the United States

    Creator:
    Van Why, Savannah L.
    Abstract:
    Many domesticated animals, especially dogs, are selectively bred within a small population to select for and “fix” certain traits. This leads to decreasing genetic diversity and the potential for inherited health issues over time. The Saluki is a relatively rare breed of dog in the U.S. The Society for the...
