Hydraulic functions of soils from physical experiments and their applications

Creator:: Su, Charles
Abstract:: Based upon the Pearson Type VIII distribution function, a general retention function which relates the saturation to the capillary pressure in disturbed soils has been discovered. This simple and yet complete function has been shown to describe precisely the imbibition as well as the drainage branch of the retention curve....

Evaluation of the torsion test for determining the shear strength of structural lumber

Creator:: Heck, Leanne Renee
Abstract:: The torsion test was evaluated as a method for determining the shear strength of full-size structural lumber. The evaluation involved an experimental length study, an experimental depth study, and a finite element study. The length study consisted of fifty nominal 2x4 specimens, ten specimens for each length, and ten American...

Testing and Modeling of a Cross-Laminated Timber Pier-and-Spandrel Seismic Retrofit Solution for Unreinforced Masonry Buildings

Creator:: Engleson, Renee M.
Abstract:: Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...

On the Imaging of Rip Currents in X-band Radar

Creator:: Kloster, Rebecca
Abstract:: Rip currents pose a serious danger to visitors of bathing beaches; they are also an important process in surf zone circulation. Haller et al. [2014] demonstrated that shore-based X-band radar can be used to compliment in situ measurements of rip currents. However, little is known of the underlying radar imaging...

Vertical jet diffusion in non linear density stratified fluid

Creator:: Baumgartner, D. J. (Donald John), 1933-
Abstract:: The simplified equations of motion proposed by Morton to determine the extent of vertical travel of a forced plume in a linear density stratified environment were re-written and solved in a way which allowed them to be applied to any non linear profile of density. For application to any specific...

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 geochemical partitioning and bioavailability of trace metals in marine sediments

Creator:: Oakley, Stewart M.
Abstract:: Trace metals in the aquatic environment are generally concentrated on the surface of solid geochemical phases which eventually become incorporated into estuarine and marine sediments. The mechanism of trace metal concentration is believed to be adsorption with various geochemical phases such as hydrous metal oxides, clays, and organic matter. Metals...

Bacterial toxicity and metabolism of three hydrazine fuels

Creator:: Kane, Donald A.
Abstract:: Hydrazine based fuels are used by the Air Force for the Titan II and Minuteman III missiles and the F-16 aircraft and by the National Aeronautics and Space Administration for propulsion systems and the Space Shuttle Program. These uses represent significant production, transportation and storage of these fuels, and, as...

Substratum-aerated-biofilm reactor for treatment of carbonaceous and nitrogenous wastewaters

Creator:: Abdel-Warith, Ahmed S.
Abstract:: This study involves the development of a biofilm reactor that supports growth of a deep biofilm on a gas permeable membrane. The reactor solution is not aerated, and oxygen is supplied through the membrane. The reactor is termed a substratum-aerated-biofilm reactor or SAB. With adequate concentrations of electron-donors and electron-acceptors,...
