Thermal Desorption Of Hazardous And Toxic Organic Compounds From Soil Matrices, Michael L. Hornsby

Theses

The purpose of this initial laboratory scale research project was to study and demonstrate the feasibility in removal of selected toxic organic compounds from soil by thermal desorption and gas purge. Applying heat and a flow of inert gas to the soil increases the volatilization and effects removal of organic compounds from soil. The work was done in two parts: First, organic solvents were injected into columns containing real and simulated soil matrices. The columns were heated to one of the four temperatures and purged with a flow of nitrogen carrier gas. The organic vapors were deposited as a plug …

Non-Linear Finite Element Of Analysis Of Reinforced Concrete Members, Chellathurai Jeyamohan

Theses

A finite element analysis of reinforced concrete members is used to study the initiation and propagation of cracks and the behavior at the interface of concrete and steel. The increase of concrete strength due to the biaxial compression and the shear capacity of the cracked elements are also considered in the analysis.

The results of the present analysis are compared with some available experimental data in beam tests. It has been found that the present analysis is capable of calculating the stress ( or moment ) and strain ( or deformation ) from zero load upto the ultimate load.

Flexural Behavior Of Portland Cement Based Composites Subjected To High Strain Rates, Edward Roland

Theses

This investigation studied the modulus of rupture and energy of rupture of mortar, concrete, and steel fiber reinforced mortar at various rates of flexural straining. The strengths of the composites were varied by changing the water cement ratios. Single point flexural loading tests were conducted on 4" x 4" x 20" specimens using a weight dropped from a height of 30" to produce the dynamic loading. Strain rates were varied between 0.1 and 1.9 per second. The inertial effects of acceleration of the specimen were taken into account.

These tests produced data that demonstrated slightly greater ratios of dynamic to …

Benzene Losses From Aqueous Solutions During Geotechnical Laboratory Testing, Konstadinos Vogiatzis

Theses

This study addressed the problem of using volatile organics in geotechnical laboratory tests. Previous experiments with volatile organics such as benzene and trichloroethylene with soils had shown significant concentration losses during the tests. The purpose of the study was to identify the sources of loss and to quantify the magnitude of loss.

Vapor - liquid equilibrium was used to predict theoretical evaporation losses of benzene from aqueous solutions. Calculations were made for both an infinite volume of air and for a finite volume. Experiments were then performed to verify the theoretical predictions.

Other losses considered were those during solution preparation, …

Performance And Design Of Labyrinth Spillway, Nosratollah Amanian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent years, the general interest in the safety of dams and reservoirs has grown appreciably. This research describes the application and design of labyrinth weirs to improve the performance of existing reservoirs and also to be used for the construction of new dams. The parameters that can affect the performance of labyrinth weirs are discussed. Tests were conducted on normal linear weirs with four different crest shapes to determine the rate of change of discharge coefficient when each type of weir is used. It is found that weirs with rounded-crest shape can pass more flow than other types of …

An Application Of The Finite Element Method And Two Equation (K And E) Turbulence Model To Two And Three Dimensional Fluid Flow Problems Governed By The Navier-Stokes Equations, John I. Finnie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Finite Element computer codes in two and three dimensions were written that solve both laminar and turbulent flow. These codes use the two equation (k and E) turbulence model to evaluate turbulent viscosity. They were tested with 29 different flow problems. The largest two dimensional turbulent problem solved is flow under a sluice gate. A three dimensional vortex flow problem was attempted but was not feasible due to the size of the available computer. The Harwell sparse matrix subroutines of the United Kingdom Atomic Energy Authority were used to solve the set of simultaneous equations. The performance of these subroutines …

Seepage Interceptor Drains And Topsoil Salinity, T R. Negus

Journal of the Department of Agriculture, Western Australia, Series 4

The Department of Agriculture established 121 trials in its Narrogin advisory district starting in 1972 to measure the effect of bulldozer and grader built seepage interceptor banks and drains on the topsoil salinity of the land downslope of them.

After 14 years of moniterin, there was no evidence that seepage interceptor drains and banks reduced the top soil salinity on 10 of the 11 sites in the Pingelly, Brookton and Wickepin Shires.

Mogumber Drainage Works Succeed, L K. Lenane

Journal of the Department of Agriculture, Western Australia, Series 4

The loss of arable farmland from soil erosion, waterlogging and salinity is a severe problem on some Western Australian farms.

When the arable land comprises only 40 per cent of the total area within the Mogumber Soil Conservation District, this loss is a real cause for concern. So too is the resulting damage to roads, siltation of railway culverts, and deaths of roadside trees from rising saline watertables.

However, drainage, contour and other works undertaken by the Mogumber Soil Conservation District have halted this degredation. Badly eroded areas that were fenced off now have a satisfactory ground cover. A wheat …

Bridge Decks And Overlays, James H. Havens, Theodore Hopwood Ii, Edgar E. Courtney

Kentucky Transportation Center Research Report

The report presents a historical perspective of the Transportation Cabinet's bridge deck construction and maintenance efforts directed toward increasing bridge deck durability.

Bridge decks crack in specific patterns that primarily depend upon bridge designs. Normal deck cracking is due to load-induced and thermal effects. Each type of cracking has a distinct pattern.

One-hundred and nineteen experimental bridge deck overlays were inspected. Included were 9 membrane bridges, 87 latex concrete overlays and 23 low-slump overlays. The overlays had been placed originally on both new and existing bridge decks on various routes throughout the state. Most of the overlays were rated in …

Expected Water Surface Levels For The Great Salt Lake, L. Douglas James

Reports

Flooding at the Great Slat Lake could become a major disaster through the high cost of coping with the rising level, sudden collapse of protective levees, failure of pumping to the West Desert to induce increased evaporation, or, fiscally, by a rapid drop in the lake level just after a large protective decision making in the private sector, provide for the design of hydrologically safe levees, and optimize pumping schemes for moving water within a partitioned lake. Doing so will require crossing major theoretical frontiers in the study of basin scale hydrology in an arid climate and for forecasting extreme …

Engineering Treatment Of Hazardous Wastewaters Utilizing Dye-Sensitized Photooxidation, Betty-Ann Naeger, R. Ryan Dupont, William M. Moore

Reports

Studies were conducted to determine the applicability of photooxidation for the degradation of selected hazardous and refractory organic compounds. These photochemical oxidation reactions occur through the transfer of energy from electronically excited sensitizer molecules which attain excited states by absorbing visible light energy. Optimum conditions for photooxidation were established based on sensitizer concentration and reaction pH for four polynuclear aromatic pollutants. The rate of photooxidation was found to be independent of the initial substrate concentration for methylene blue-sensitized reactions, and dependent on substrate concentration for solutions without a sensitizing dye. Photolysis of substrate mixtures established acridine and anthracene as photochemically …

Elastic-Plastic Analysis Of Axisymmetrically Loaded Isotropic Circular And Annular Plates Undergoing Large Deflections, Aiman Raji Akileh

Dissertations and Theses

The concept of load analogy is used in the elastic and elastic-plastic analysis of isotropic circular and annular plates undergoing moderately large deflection. The effects of the nonlinear terms of lateral displacement and the plastic strains are considered as additional fictitious lateral loads, edge moments, and in-plane forces acting on the plate. The solution of an elastic or elastic-plastic Von Karman type plate is hence reduced to a set of two equivalent elastic plate problems with small displacements, namely, a plane problem in elasticity and a linear elastic plate bending problem. The method of finite element is employed to solve …
