Aqueous-organic partition coefficients for Rn-222 and their application to Radon analysis by liquid scintillation methods

Creator:: Cantaloub, Michael G.
Abstract:: A method is described for determining the partition coefficient, K, for radon gas distributed between an aqueous phase and an organic solvent. The method uses sequential extractions of radon into equal volume aliquots of organic solvent. The radon-laden organic liquid is then counted on a liquid scintillation analyzer with alpha-beta...

Pile group analysis considering rigid and semirigid foundation conditions

Creator:: Winchester, Jack LeRoy
Abstract:: The structural behavior of pile groups (dolphins) is analyzed considering two types of boundary conditions. First the individual piles of the group are assumed to be rigidly embedded in the soil. In the second analysis the more realistic case is considered where the soil foundation is allowed to yield. The...

The character and biological treatability of log pond waters

Creator:: Hoffbuhr, Jack Wayne
Abstract:: A study was conducted to determine the chemical nature and the biological treatability of log pond water. Various analyses including total solids, volatile solids, suspended solids, dissolved oxygen, pH, COD, BOD₅, BOD₂₀, total Kjeldahl nitrogen, nitrate nitrogen, phosphate, and PBI were performed on water samples from each of the four...

Numerical and physical modeling of wave forces on A-Jacks units

Creator:: Wise, Larry
Abstract:: A numerical model is developed to estimate wave forces on A-Jacks armor units. The forces include drag, inertia, buoyancy, and slamming as the unit penetrates the free surface. The wave force model is used to determine the rigid body motions of the units. Bulk forces on a matrix of units...

An efficient high-performance computing based three-dimensional numerical wave basin model for the design of fluid-structure interaction experiments

Creator:: Nimmala, Seshu B.
Abstract:: Fluid-structure interaction (FSI) is an interesting and challenging interdisciplinary area comprised of fields such as engineering- fluids/structures/solids, computational science, and mathematics. FSI has several practical engineering applications such as the design of coastal infrastructure (such as bridges, levees) subjected to harsh environments from natural forces such as tsunamis, storm surges,...

Improving the Performance of High Early Strength Concrete by Controlling Self-Desiccation and Mitigating Shrinkage

Creator:: Wilson, Cameron A.
Abstract:: High early strength (HES) concrete is becoming increasingly used to repair damaged concrete pavement sections. The use of HES concrete enables the repaired pavement to be opened to traffic within hours of placing the concrete. A common approach used for the rapid repair of concrete pavement consists of closing a...

Characterization of Stormwater Runoff from a County Maintenance Facility and Evaluation of Temporal Performance of Bioswale in Its Treatment

Creator:: Gyawali, Kshitiz
Abstract:: In the last few decades, a lot of studies have been conducted to study about the quality of stormwater runoff from various sites and conditions. Highways, residential areas, and commercial sites are the focus of most of these studies while limited studies have done examination of stormwater from Maintenance and...

Numerical modeling of full-coupled fluid-structure interaction

Creator:: Yuk, Dongjun
Abstract:: A numerical model for the simulation of fully-coupled fluid-structure interaction is developed in this study. In modeling the fluid, the Reynolds Averaged Navier-Stokes equations are solved for an incompressible viscous fluid field and a k-ε model is employed for turbulence computations. Hydrodynamic forces obtained by the integration of the fluid...

Bench-scale study for the bioremediation of chlorinated ethylenes at Point Mugu Naval Air Weapons Station, Point Mugu California, IRP Site 24

Creator:: Keeling, Matthew Thomas
Abstract:: Laboratory scale microcosm studies were conducted using site specific groundwater and aquifer solids to assess the feasibility of stimulating indigenous microorganisms in-situ to biologically transform Trichloroethylene (TCE) and its lesser chlorinated daughter products dichloroethylene (DCE) and vinyl chloride (VC). Three different treatments were conducted to determine the best approach for...
