  • A study on the oxidation of sulfides in estuarine waters

    Creator:
    Korpalski, Thomas Paul
    Abstract:
    Waters of various salinities were secured from the Umpqua estuary, the Umpqua River, and the open ocean near the mouth of the estuary. The rate of oxidation of sulfides in these various waters was investigated to assess the potential longevity of free sulfides in estuarine waters. The rate of disappearance...

  • Transport and adsorption of proteinanceous particles during flow through porous media

    Creator:
    Yamamoto, Tokuo
    Abstract:
    This is a fundamental study of the mechanism of protein particle removal during flow through sandy soil. Mathematical models for diffusion-adsorption and diffusion-convection-adsorption processes were developed and compared with experimental data. An attempt was made to calculate the distance over which the adsorption forces act. The differential equation for the...

  • Laboratory Observations of Tsunami-Driven Debris Damming with Comparison to ASCE 7-22 Minimum Design Loads

    Creator:
    Doyle, Kellen C.
    Abstract:
    Tsunami inundation of coastal communities can impose a wide array of forces on the built environment. Forces generated by tsunami-driven debris damming have the potential to cause failure of coastal structures and further accumulate flow-entrained debris. Since tsunami-resilient design standards were adopted by ASCE in 2016, debris damming considerations have...

  • The effect of selected insecticides upon biochemical oxidation

    Creator:
    Norris, Francis Warren, Jr.
    Abstract:
    A study to determine the effect of certain synthetic organic insecticides on the Biochemical Oxygen Demand (BOD) Test was performed. BOD tests on a standard glucose-glutamic acid substrate were conducted while in the presence of dieldrin, dichlorodiphenyltrichloroethane (DDT), or diazinon. From the BOD data, the following parameters were obtained: 1....

  • Economic comparisons of different highway networks in a given region

    Creator:
    Ergün, Tevfik
    Abstract:
    This thesis presents an economic comparison of three different highway networks which serve an area of 64 miles by 83 miles in size. Each network is designed to carry the same traffic between any two towns but is different in total length. Costs of right of way, excavation, pavement and...

  • A review of research on shear and diagonal tension in reinforced concrete beam

    Creator:
    Yang, Jui-Tsung
    Abstract:
    Resistance of reinforced concrete beams to diagonal tension was studied in a series of papers which included beams without web reinforcement and beams with various types of web reinforcement. The magnitude of the loading causing the formation of initial diagonal tension cracks depended primarily on the dimensions of the cross...

  • Air photo analysis of waste dispersion from ocean outfalls

    Creator:
    James, Wesley Pierce
    Abstract:
    Aerial photography provides a method of analyzing dispersion of wastes that are discharged into the ocean. This method is more comprehensive than conventional boat sampling in dispersion studies. The photographic technique permits waste concentrations to be measured throughout the plume in one instant; thereby allowing the diffusion analysis to be...

  • The Pozzolanic Reactivity Test and the Properties of Portland Limestone Cement

    Creator:
    Choudhary, Antara
    Abstract:
    The pozzolanic reactivity test (PRT) is used to quantify the pozzolanic reactivity of supplementary cementitious materials (SCMs). The PRT computes reactivity by measuring heat release (Q) and calcium hydroxide (CH) consumption, as interpreted using thermodynamic modeling. The robustness of PRT is examined by experimentally varying CH-to-SCM ratio, solution-to-solid ratio, sulfate...

  • A study of the quantity and distribution of bark debris resulting from log rafting

    Creator:
    Williamson, Kenneth J.
    Abstract:
    A study was conducted to determine the quantity and distribution of bark debris resulting from log rafting. Three distinct problems were studied: (I) the quantity of bark dislodged from the logs while being placed in the rivers and during transport in log rafts; (2) the percentage of the bark that...
