  • Petroleum refinery residuals : a recycling feasibility study

    Creator:
    Hoffman, Andrew J.
    Abstract:
    Large quantities of unused heavy oil and residual waste products from the petroleum refining industry were deposited in on-site landfills, pits, and lagoons, prior to the promulgation of regulations governing their disposal and technology development that would further utilize and/or recycle these materials. Contacting petroleum products with sulfuric acid for...

  • The effect of dissolved oxygen concentration on the activated sludge process

    Creator:
    Swanson, Gregory R.
    Abstract:
    Since the introduction of pure oxygen activated sludge systems in the late 1960's, proponents have claimed several advantages resulting from the elevated dissolved oxygen (DO) levels maintained. However, numerous comparative studies have failed to produce a consensus of professional opinion regarding the validity of these claimed advantages. The purpose of...

  • Multi-hazard framework and analysis of soil-bridge systems : long duration earthquake and tsunami loading

    Creator:
    Carey, Trevor J.
    Abstract:
    During the 2011 Great East Japan Earthquake and Tsunami, numerous bridge structures were damage or destroyed. The damage to bridge systems was caused by long duration strong ground shaking, tsunami inundation forces, or both. Long duration strong ground shaking from subduction zone earthquakes and the multi-hazard scenario of combined earthquake...

  • Soil-bridge interaction during long-duration earthquake motions

    Creator:
    Romney, Kyle T.
    Abstract:
    Earthquake engineering analyses are often performed using shallow, crustal earthquake motions (e.g., 1940 El Centro). However, large areas of the world are subject to subduction zone earthquake motions (e.g., the Pacific Northwest). A subduction zone earthquake motion is characterized by its long duration (e.g., strong shaking lasts for more than...

  • Disposal of sandy pipeline dredge spoils by end dumping

    Creator:
    Pyles, Marvin Russell
    Abstract:
    Channel maintenance operations in the rivers and harbors of the United States annually require the disposal of over 320 million cubic meters of dredge spoils. As the availability of suitable land sites diminishes, open water disposal presents an attractive yet controversial alternative method. For open water disposal to be acceptable,...

  • Evaluation of fabric reinforcement of the roadway structure

    Creator:
    Lavansiri, Direk
    Abstract:
    An evaluation of fabric reinforcement of the roadway structure is made. The study includes a parametric analy sis using layered elastic theory and a series of large scale model tests. The parametric. study analyzes the stresses and strains of roadway structures with a fabric layer between tna surface layer and...

  • Modeling of ammonia losses in sprinkler application of animal wastes

    Creator:
    Pote, Jonathan W. (Jonathan Woodrome)
    Abstract:
    A model to predict ammonia losses from sprinkler applied animal wastes was developed; in order to accomplish this, a review of literature was performed to determine possible methods of predicting ammonia losses during sprinkling. As adaptability to a large variety of situations was considered of maximum importance, the number of...

  • Evaluation of finite element techniques for soil reinforcement applications

    Creator:
    Berg, Ryan Robert
    Abstract:
    A literature review and a computer study are conducted to identify the requirements of finite element programs for the specific use of discrete analyses of reinforced soil structures. The utility of six commercially available programs are appraised with respect to the identified requirements. The results of the study are directed...

  • Determination of equilibrium partial pressure of ammonia gas above anaerobically digested sewage sludge

    Creator:
    English, Charles Joseph
    Abstract:
    A laboratory study of anaerobically digested sewage sludge was performed to measure equilibrium constants for ammonia in the sludge. Measured constants describing the solution and dissociation of ammonia in sludge were compared to theoretical constants obtained from thermodynamic data. No significant difference was found between these two sets of constants....

  • An investigation of the feasibility of a cutbank slope design method based on the analysis of natural slopes

    Creator:
    Keener, Quentin Roosevelt
    Abstract:
    The failure of cutbanks is a major problem encountered by those who construct low-cost roads in naturally forested residual soils. Attempts have been made to lessen the severity of failures by classifying certain soil areas as to their susceptibility to failure, in addition to bringing past design experience into play...
