  • Modeling hop kilning with respect to energy consumption and drying kinetics

    Creator:
    Thomas, Matthew W.
    Abstract:
    Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

  • A study of factors affecting the extraction of flavor when dry hopping beer

    Creator:
    Wolfe, Peter Harold
    Abstract:
    This work set out to examine the methodologies of dry hopping, compare different hop materials, and look at the extraction behavior of different types of hop compounds. This work consists of two discrete studies, where the first study informed the design of the second. The first study measured the concentrations...

  • The simulated and measured performance of rotary dryers used to dry wood waste fuels using boiler exhaust gases

    Creator:
    Kirk, Raymond W.
    Abstract:
    This study evaluates the feasibility of retrofitting a rotary dryer to a hog fuel boiler, using the boiler exhaust gases as the drying medium. Two simulation models were developed. As substantiated by experimental measurement of existing boiler/dryer systems, each model accurately predicts system performance given site-specific parameters such as boiler...

  • Evaluation of six tools for estimating woody biomass moisture content

    Creator:
    Becerra Ochoa, Fernando Amador
    Abstract:
    Woody biomass transportation costs and market values/costs are strongly correlated with the woody biomass moisture content. Properly managing moisture content can potentially lead to economic and environmental advantages in biomass energy markets. Good management requires accurate moisture content measurements. Therefore, availability of accurate, precise, reliable, and efficient tools to assess...

  • The photoelastic coating method applied to the stress analysis of wood

    Creator:
    Fritz, Dennis William
    Abstract:
    The merits of the photoelastic coating technique as applied to wood were evaluated. Comparative tests were made on 12 nominal two-by-four Douglas Fir boards. The object of these tests was to determine the limitations of this technique, such as accuracy and complexity of experimental procedure. Correlation of the experimental results...

    Creator:
    Saiyed, Waqar Hassan
    Abstract:
    The present thesis is about the electric power distribution system for the city of Mecca, in Saudi Arabia. The distribution system of Mecca started suddenly, grew haphazardly and developed quickly with a load factor as high as 38%. Lack of planning, records and training plus insufficient experience of management evolved...

  • 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...

    Peterson, Ella M.
    Abstract:
    This paper discusses research concerning redware vessel sherds found in an archaeological excavation at Oregon's historic Champoeg State Park, and comparative artifacts from four known Oregon and Washington late nineteenth pottery production sites. Visual and Instrumental Nuclear Activation Analysis comparison studies were conducted on samples from each site. The New...
