  • Influence of expansive soils on structures in the Eugene area

    Creator:
    Bonell, John Alexander
    Abstract:
    Expansive soils in Eugene, Oregon present a problem to residents, consultants, contractors, and the city government. During the years 1977 to 1979, the nature and extent of the problem was identified, including an outline of the local occurrence of expansive soils and possible engineering solutions to the most often encountered...

  • Aerobic degradation of chlorophenols

    Creator:
    Wang, Gongming
    Abstract:
    Chlorinated phenols are toxic compounds and often released into natural environments from improper disposal or non-point sources. One important factor in assessing the environmental fate and transport is the rates of microbial degradation in soils and natural waters. In this study, eight chlorophenols (4-chlorophenol (4-CP), 2,4-dichlorophenol (2,4-DCP), 3,4-dichlorophenol (3,4-DCP), 3,5-dichlorophenol...

  • Fate of ammonia volatilized from a confinement livestock facility

    Creator:
    Hoffman, Eldon Randall
    Abstract:
    A conceptual model was developed to further the understanding of the evolution and fate of volatilized ammonia in the atmosphere. Recent trends in livestock rearing have been toward confinement facilities in which high animal concentrations are maintained. One of the impacts of these facilities has been increased local concentrations of...

  • Bacterial toxicity and metabolism of three hydrazine fuels

    Creator:
    Kane, Donald A.
    Abstract:
    Hydrazine based fuels are used by the Air Force for the Titan II and Minuteman III missiles and the F-16 aircraft and by the National Aeronautics and Space Administration for propulsion systems and the Space Shuttle Program. These uses represent significant production, transportation and storage of these fuels, and, as...

  • Substratum-aerated-biofilm reactor for treatment of carbonaceous and nitrogenous wastewaters

    Creator:
    Abdel-Warith, Ahmed S.
    Abstract:
    This study involves the development of a biofilm reactor that supports growth of a deep biofilm on a gas permeable membrane. The reactor solution is not aerated, and oxygen is supplied through the membrane. The reactor is termed a substratum-aerated-biofilm reactor or SAB. With adequate concentrations of electron-donors and electron-acceptors,...

  • Wood materials and shearwalls of older light-frame residential structures

    Creator:
    Carroll, Cameron T.
    Abstract:
    Light-frame construction practices and materials have changed greatly over the past 100 years. Contemporary research has focused on modern construction; thus, we know a great deal about the behavior of modern lightframe buildings under lateral forces. However, there are many light-frame buildings that were built prior to the introduction of...

  • An Efficient Workflow and Accuracy Assessment for ICESat-2 and Multispectral Imagery Fusion for Bathymetric Mapping

    Creator:
    Babbel, Benjamin J.
    Abstract:
    Interest in mapping bathymetry from multispectral satellite imagery has grown steadily since the 1970s. Notwithstanding the significant advancements made during this time, one limitation is that the group of algorithms collectively referred to as Satellite Derived Bathymetry (SDB) generally require “seed depths,” hindering their use for areas lacking reliable reference...

  • The seismic geotechnical modeling, performance, and analysis of pile-supported wharves

    Creator:
    McCullough, Nason J.
    Abstract:
    This dissertation presents the results of a research effort conducted to better understand the seismic performance and analysis of pile-supported wharves. Given the limited number of well-documented field case histories, the seismic performance of pile-supported wharves has been poorly quantified, and the analysis methods commonly employed in engineering practice have...

  • Finite element modeling of gusset plate failure using OpenSees

    Creator:
    Walker, Andrew J.
    Abstract:
    The collapse of the I-35W Bridge in Minneapolis, MN in 2007 prompted an investigation into the design and inspection of the steel truss bridges. Further investigation into the collapse revealed that a gusset plate experienced sway buckling, causing the bridge failure. This bridge failure motivated research into the analysis and...

  • Wave field patterns generated by wave energy converters

    Creator:
    McNatt, J. Cameron
    Abstract:
    The eventual deployment of wave energy converters (WECs) on a commercial scale will necessitate the grouping of devices into arrays or "wave farms," in order to minimize overhead costs of mooring, maintenance, installation, and electrical cabling for shoreward power delivery. Closely spaced WECs will interact hydrodynamically through diffracted and radiated...
