  • A Paleomagnetic and Environmental Magnetic Record from the Eastern South Pacific Sector of the Southern Ocean (0-1.7 Ma): IODP Site U1543

    Creator:
    Monito, Lindsey
    Abstract:
    This research presents a u-channel based study of the natural remanent magnetization (NRM), the laboratory magnetization, Anhysteretic Remanent Magnetization (ARM), and magnetic susceptibility (k), from the upper 100 m of International Ocean Discovery Program (IODP) Expedition 383 Site U1543 in the eastern South Pacific sector of the Southern Ocean. Alternating...

  • Tidal influence on downstream fining in gravel-bed rivers

    Creator:
    Coles, Derron Rafiq
    Abstract:
    This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

  • Total Synthesis of Tryptamine Alkaloids from the Arundo and Leuconotis Genera

    Creator:
    Ferreira, Andrew
    Abstract:
    The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...

  • Multi-Technique Characterizations of Natural and Biomimetic Adhesives

    Creator:
    Fowler, James E.
    Abstract:
    There have been many attempts to characterize and mimic natural fluid-based adhesive systems. However, very few of these studies have examined surface or interfacial interactions between adhesive and substrate. Furthermore, until now no study has used a combination of surface analytical and kinematic techniques to determine the precise chemical mechanisms...

  • Estimating Drag and Roughness along a Near-Vertical Ice-Ocean Boundary on a Grounded Iceberg

    Creator:
    Cohen, Nadia
    Abstract:
    Ice–ocean interactions have profound consequences for the ocean and climate, influencing the rate of sea level rise. Submarine melt is commonly parameterized using a three-equation formulation for the heat, salt, and momentum conservation equations coupled to a buoyant plume model, together called plume-melt theory. However, recent direct observations of terminus...

  • Quest for Occupational Identity : Examining Career Resilience, Career-Related Adversity, and Career Decision Difficulty during Emerging Adulthood

    Creator:
    Dressler, June L.
    Abstract:
    Emerging adults often encounter obstacles and adversity in pursuit of occupational identity. College counselors are responsible for delivering mental health, wellness, and career services to distressed students facing unprecedented challenges to enter the workplace. The purpose of this study was to investigate how counselors can promote career resilience in emerging...

  • Techno-economic analysis of extraction curcumin from turmeric

    Creator:
    Kunta, Naveen
    Abstract:
    Curcumin is a yellow colored bioactive pigment present in the spice turmeric (Curcuma longa). It has been identified with antioxidant, anti-inflammatory, anticancer, antibacterial, antirheumatic, antidiabetic and antiviral properties. It is extensively used in nutraceutical, food and cosmetics industry. Fueled by its potential uses in research community and rise in awareness...

  • Sustainability of a forest preservation project in India : the case of the Kalakad Mundanthurai Tiger Reserve

    Creator:
    Balasubramanian, Maniselvan
    Abstract:
    Numerous development projects are implemented in developing countries to attain economic and ecological development. However, in most cases, the encouraging results observed during the implementation phase terminated with the project period, raising concerns on these projects' sustainability after the project period has ended. This study focuses on this sustainability issue...

  • Top-Down Effects of Wildlife and Bottom-Up Drivers of Soils and Productivity in Intensively Managed Forest Plantations in the Northern Oregon Coast Range

    Creator:
    Frey, David W.
    Abstract:
    In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...

    Creator:
    Taylor, Ryan W
    Abstract:
    Since the 1890s, American federalism has been perceived as being unique in the world by having two different levels of government operating within the same jurisdiction without influencing one another. Modern scholars call into question the validity of this basic assumption, but few have published quantitative evidence to reject its...
