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...

Evaluating dairy waste management systems ̓influence on fecal coliform concentration in runoff

Creator:: Grismer, Mark Edward
Abstract:: This paper examines the environmental factors influencing the die-off and transport of fecal coliform bacteria present in wastes applied to the land surface. These factors are examined specifically for dairy waste management systems and the net effect each system has on runoff water quality. A model is developed that considers...

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....

The static and dynamic analysis of discretely represented moorings and cables by numerical means

Creator:: Dominguez, Richard Frank
Abstract:: Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...

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...

Effect of an Idealized Mangrove Forest of Moderate Cross-shore Width on Loads Measured on a Sheltered Structure and Comparison with Predicted Forces

Creator:: Mitchell, William T.
Abstract:: As coastal communities face increasing chronic and acute hazards, nature-based coastal engineering solutions have experienced a rapid growth in popularity and interest. Recent works on this topic have shown that “Green Infrastructure” may be effective at mitigating coastal hazards and therefore provide sustainable adaptation alternatives to traditional engineering solutions such...

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...

Development of Authentic Engineering Curriculum through Collaborative Development: Research on Development and Adoption

Creator:: Cross, Matthew J.
Abstract:: Background: Studies indicate that problems utilized in traditional undergraduate engineering education do not adequately prepare students for the workforce. Calls to implement authentic, ill-structured problems into upper level engineering experiences may address this issue but adopting authentic engineering problems without considering barriers to adoption of faculty has not been fully...
