  • The degradation of kraft pulping wastes in estuarine waters

    Creator:
    O'Neal, Gary Lewis, 1938-
    Abstract:
    The degradation of kraft pulping wastes in estuarine waters was measured in terms of the following parameters: five-day 20°C B.O.D., the Pearl-Benson Index, and toxicity to the bay mussel (Mytilus edulis L.). The waste tested was the total effluent from a combined pulp and paper mill producing 430 tons of...

  • The use of LiDAR to identify forest transportation networks

    Creator:
    Beck, Storm J. C.
    Abstract:
    The production of high value non-conventional products, such as long utility poles; or the production of low value bulky products, such as chips or grindings; provide opportunities for forest owners to increase value from their forests. The transport of these products requires the use of specialized trucks and trailers. However,...

  • Alum coagulation in conjunction with the activated sludge treatment of corn processing waste water

    Creator:
    Jensen, Harold LeRoy, III
    Abstract:
    The treatment of waste water from a corn freezing process by activated sludge with the aid of alum coagulation was investigated. Both high and low energy level systems were observed with good flocculation occurring at the low energy level. Because poor flocculation occurs at high energy level conditions, alum was...

  • Digitalization of Construction-Phase Information Management by Project Owners

    Creator:
    Jahanger, Qais K.
    Abstract:
    Construction is a strategically important industry and its productivity has a significant impact on a nation’s economy. However, productivity in the US construction industry has been widely reported to be on the decline. Among several causes identified, the lack of innovation in project management practices has been described as having...

  • A formal model of construction safety and health risk management

    Creator:
    Hallowell, Matthew R.
    Abstract:
    Despite recent efforts to improve site safety, construction still accounts for a disproportionate injury and illness rate. According to the 2007 injury and illness data released by the National Safety Council, the construction industry has a fatality and disabling injury rate that is approximately three times higher than the all-industry...

  • Environmental Regulations Reconsidered : Identifying Incentives and Barriers to Environmental Performance

    Creator:
    Craig, Kathleen D.
    Abstract:
    Attention has been drawn to the observation that environmental benefits under the current regulatory approaches are diminishing with respect to increased pollution control costs. Regulators have begun to appreciate that while environmental gains can still be achieved under the current command and control system, the most significant environmental gains have...

  • Application of quality function deployment in the conceptual design of a construction project

    Creator:
    Hinkle, Verda O.
    Abstract:
    Quality Function Deployment (QFD) is a product development process that assures the needs and desires of the customer are heard and heeded during the design, development and production of a product. Though it has been used successfully in other industries, only a few companies in the U. S. Engineering and...

  • Light-frame versus timber frame : a study in quantifying the differences

    Creator:
    Malone, Brian P.
    Abstract:
    The objective of this study was to compare light wood framing and traditional timber framing quantitatively through environmental impact assessment and load path analysis. This research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and the design of structures considered within reflect the general characteristics...

  • Development of a method to elucidate biodegradation pathways of chlorinated one and two carbon compounds using a gas-permeable-membrane-supported methylotrophic biofilm

    Creator:
    Ryan, Kelly M.
    Abstract:
    A gas-permeable-membrane-supported (GPMS) biofilm consisting of methylotrophic bacteria was effective in degrading chlorinated methanes, ethanes, and ethenes. The biofilm was developed on a gas-permeable fabric (Goretex, W.L.Gore & Associates, Elkton, Maryland) that divided a reactor vessel into a liquid compartment and a gas compartment. Goretex is a nylon-backed teflon mesh...

  • Behavior of a compliant wave-current barrier

    Creator:
    Kerper, Dale R.
    Abstract:
    This study includes an analytical solution to the wave-current barrier interaction problem and large scale experiments to validate the theory. The boundary value problem is solved mathematically by characterizing the flow field and barrier motion separately, then coupling the relationships with the appropriate kinematic and dynamic boundary conditions. The flow...
