Estuarine sediment controls on trace metal distributions

Creator:: Davies-Colley, Robert J.
Abstract:: Sediments are the major compartment in aquatic environments for many materials of toxic or nutrient concern. The lack of knowledge of the phase associations of toxic metals in sediments is the largest deficiency in our understanding of the environmental hazard posed by metal contamination. This study examined the sedimentary partitioning...

Adsorption of hexavalent and trivalent chromium to a clayey silt soil : batch kinetic and equilibrium studies

Creator:: Bean, Gregory R.
Abstract:: Chromium, an element of widespread use, is toxic in some forms. Improper disposal of waste chromium products has resulted in contamination of many sites throughout the United States, including the United Chrome Products Superfund site in Corvallis, Oregon. A better understanding of chromium chemistry is needed to facilitate the remediation...

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...

Alternate Methods for the Extraction and Measurement of Pore Solution in Fresh Concrete

Creator:: Biever, Joseph
Abstract:: Knowledge of the pore solution composition and pore solution resistivity can be helpful for determining the durability of concrete structures. Most notably, pore solution resistivity can be used in the calculation of the formation factor of concrete, which is a ratio of the electrical resistivities of concrete and its pore...

Measuring and Correcting the Electrical Resistivity of Concrete Pore Solution in Fresh Mixtures

Creator:: Biever, Joseph H.
Abstract:: A vital aspect of concrete construction is quality assurance and control (QA/QC). Engineered structures must meet pre-determined and agreed-upon strength and durability requirements. Concrete falls into a specific category of infrastructure material because in most cases, these strength and durability requirements cannot be found until the material has at least...

Biodegradability and oxygen uptake studies on resuspended estuarine bottom sediments

Creator:: Touhey, Robert James
Abstract:: A study was conducted to determine the oxygen uptake rate of resuspended estuarine bottom sediments and the biodegradability of the organic matter released during resuspension. Oxygen uptake was measured on a Gilson Differential Respirometer and the percent biodegradability was calculated by determining the soluble organic carbon on a Beckman Carbonaceous...

Nonlinear diffraction theory by an eigenfunction expansion of the Green's function

Creator:: Chen, Min-Chu
Abstract:: A second-order nonlinear diffraction theory is developed for a large diameter circular cylinder under the action of surface gravity waves of finite amplitude in water of-finite depth. Boundary value problems are derived by using a perturbation expansion and the solutions for the diffracted waves are given in terms of Fredholm...

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...

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...
