  • Efficiency of a direct contact condenser in the presence of the noncondensable gas air compared to a tube and shell condenser

    Creator:
    Lebsack, Jonathan M.
    Abstract:
    Steam distillation is the traditional method used for the extraction of peppermint oil. This process is able to remove approximately 20% of the oils from the leaves of the plant. It is a very costly and un-sustainable process due to the release of carbon emissions. Solvent free microwave extraction promises...

  • Preserving the Planar Dynamics of a CompliantBipedal Robot with a Yaw-Stabilizing Foot Design

    Creator:
    Abate, Andrew M.
    Abstract:
    The ATRIAS agile humanoid robot, along with a number of other spring-mass walking machines, currently have two instabilities: one resulting from inertial forces on the torso which cause the robot to spin like a top, and another resulting from stiff ground collisions which cause chattering of the point-contact toes. This...

  • From running birds to walking robots : optimization as a unifying framework for dynamic bipedal locomotion

    Creator:
    Hubicki, Christian M.
    Abstract:
    Bipedal locomotion is a complex phenomenon to understand and control, making it difficult for legged robots to achieve the speed, agility, efficiency, and robustness of their animal counterparts. This thesis argues for the use of numerical optimization to investigate and implement bipedal control as it applies to biology, dynamical models,...

  • The Design Freedoms of a Novel Cable-Driven Manipulator

    Creator:
    Layng, Brian M.
    Abstract:
    Legged locomotion in robotics benefits from engineered hardware dynamics such as configuration-dependent, nonlinear transmissions and compliance. This thesis introduces a novel cable driven leg that allows the design of configuration-dependent transmission ratios while also permitting the addition of compliance in line with the cables to achieve compliant legged locomotion. The...

  • Uranium and technetium bio-immobilization in intermediate-scale permeable reactive scale barriers

    Creator:
    Sapp, Mandy M.
    Abstract:
    Groundwater at Oak Ridge National Laboratory's Field Research Center (FRC) is contaminated with U(VI) and Tc(VII), has pH values as low as 3.3, and nitrate concentrations as high as 120 mM. The objective of this research was to determine if in-situ bio-immobilization is a viable treatment alternative for this water....

  • Uranium and technetium bio-immobilization in intermediate-scale physical models of an in situ bio-barrier

    Creator:
    Michalsen, Mandy M.
    Abstract:
    Metal and hydrogen ion acidity and extreme nitrate concentrations typical of Department of Energy (DOE) legacy waste sites pose formidable challenges to successful implementation of in situ bio-immobilization. Intermediate-scale (~ 2.5 m), flow through models of an in situ bio-barrier were constructed to investigate U and Tc removal from groundwater...

  • Tide-topography coupling on a continental slope

    Creator:
    Kelly, Samuel M.
    Abstract:
    Tide-topography coupling is important for understanding surface-tide energy loss, the intermittency of internal tides, and the cascade of internal-tide energy from large to small scales. Although tide-topography coupling has been observed and modeled for 50 years, the identification of surface and internal tides over arbitrary topography has not been standardized....

  • Exploring Student Reflections Towards an Agricultural Internship

    Creator:
    Henderson, Thomas M.
    Abstract:
    The agricultural industry across the United States is experiencing a shortage of qualified and interested young professionals who aspire to enter the agricultural sector. Internships have largely been used as an effective hands-on learning tool, exposing college students to an array of occupational skills and expectations in hopes of creating...

  • A Bayesian Treatise on the Replication Crisis in Science

    Creator:
    Gibson, True E.
    Abstract:
    Over the past decade, it has come to light that many published scientific findings cannot be reproduced. This has led to the replication crisis in science. Many researchers feel that they can no longer trust much of what they read in scientific journals, and the public is becoming ever more...

  • Politicized Collective Illness Identity and Boundary-Spanning in Western Montanan Community Health Workers: An Ethnographic Study

    Creator:
    McQuillan, Kindra
    Abstract:
    Background: Against global health disparities and a shortfall of medical personnel, community health workers (CHWs) promise a solution based in lived experience and connection to the health system. To address global and upstream health determinants, CHW programs engage the perspectives of both the workers they employ and the communities they...
