Velocity And Kinetic Energy Distribution Of A Submerged Jet., Patrick Shepard Couch

Masters Theses

"The velocity distribution in a cylindrically bounded region of water induced by a submerged axisynnnetric jet of water, has been investigated. Velocity profiles at successive levels were constructed. The continuity equation was shown to be only approximately verified by the velocity profiles.

The kinetic energy for each level was computed and given mathematical expression"-- Abstract, p. 2

A Study Of Cation Exchange And Soil Properties, Arthur G. Follett

Masters Theses

“The objective of this investigation is to study the effect of clay content and cation exchange capacity on the liquid and plastic limits of a soil system in the natural, flocculated, and dispersed states. Putnam and Clarksville natural soils found extensively in Missouri and a synthetic soil composed of Kaolin clay and Clarksville fine sand and silt were tested.

The results of the investigation indicate that a general relationship exists between the high cation exchange capacity of a soil and the extreme variances of the liquid and plastic limit values for the flocculated and the dispersed states. The cation exchange …

The Toxic Effects And Fate Of Selected Pesticides In Natural Water., Donald Lee Evans

Masters Theses

"The extensive application of synthetic organic pesticides in the United States has created many problems, particularly with respect to fish life. While a number of investigations have been undertaken to determine the toxicity of several pesticides to various species of fish, a great deal of research work is needed before the problem is completely understood.

The individual toxicities of DDT, BHC, 2.,4-D, and Sevin to western golden shiners were determined by means of the bioassay procedure at a t empera t ure Of 16oc. The four chemicals studied were found to be toxic to the test fish with Median Tolerance …

Effect Of Poly-Ethylene Glycol, A Non-Shrinking Agent, On Strength Properties Of Concrete., Vasantrai Vallabhbhai Desai

Masters Theses

"This thesis describes laboratory test made on plain concrete cylinders and ~earns for compressive strength, flexural strength, durability and shrinkage, using poly-ethylene glycol (ElOOO) as a non-shrinking admixture. The tests were conducted in the Materials Laboratory of the Civil Engineering Department.

The test results show that poly-ethylene glycol has the effect of reducing the compressive and flexural strength of plain concrete. The admixture also has the effect of reducing shrinkage, and reversing it, causing expansion with large percentage of its use. For the number of cycles of alternate freezing and thawing reported the admixture did not have any effect on …

A Study Of The Stabilization Of Putnam Silt Loam With Large Organic Cations, George C. Bennett Jr.

Masters Theses

"Laboratory tests were conducted to determine if Aliquat, a quaternary ammonium chloride compound, could be used to change the physical properties of Putnam silt loam. The effects of adding varying amounts of Aliquat to the soil were measured in terms of the results of Atterberg limits tests, the moisture-density relationship, unconfined and triaxial compressive strength, and capillary adsorption characteristics. A small change in the Atterberg limits, the optimum moisture content, and the maximum dry density was noted. An increase in the unconfined compressive strength and a reduction in the moisture adsorption potential was accomplished by the addition of 0.25 and …

The Effect Of The Static Compaction On The Mechanical And Physical Properties Of Asphalt Concrete Hot-Mixes, Abdel-Gawad A. Bahgat

Masters Theses

"The objective of this investigation was to study the effect of the static compaction effort upon the physical and mechanical properties of asphalt concrete hot mixes. To study the effect of the static compaction upon the physical properties of the asphalt mixes, six mixes were prepared using hard, well graded crushed limestone as an aggregate, blended with an 85-100 penetration grade asphalt cement. The control mix was prepared and tested in accordance with the Marshall method for mix design. The other five mixes were prepared and tested using the same procedures of Marshall except for compaction, where five different static …

Effect Of Hydroxyethyl Cellulose On Properties Of Concrete At Early Ages., Vipinchandra R. Shah

Masters Theses

"In this investigation, hydroxyethyl cellulose was used as an admixture in plain concrete. The admixture was tested for its effect on the compressive strength of plain concrete cylinders and for its effect on the flexural strength of plain concrete beams. Specimens were also tested for freeze-thaw durability and shrinkage.

The test results indicated that hydroxyethyl cellulose has the effect of increasing the compressive strength and decreasing the flexural strength of plain concrete. The rapid freezing and thawing tests showed that the durability increases with increase in amount of admixture.

The tests were carried out in the Materials Laboratory of the …

Determination Of Transient Temperature Stresses In Plates, Teh Yu Hu

Masters Theses

“The purpose of this thesis is to determine the transient temperature stresses in two-dimensional plate structures restrained against rotation at the ends but not restrained against elongation. In this investigation, only one-dimensional heat flow is considered. The heat flow is first treated as a problem in pure conduction and then the effects of convection through a boundary layer are considered.

The differential equation of transient heat conduction is solved by Fourier series and Duhamel’s theorem, and a graphical method of solution for temperatures in terms of dimensionless parameters is presented.

Solution of this problem is valid for a semi-infinite plate …

The Effect Of Plastic Deformations On Grain Boundaries., Jayendra Jamnadas Shah

Masters Theses

"The purpose of this study is to determine the effect of the plastic deformations on the grain boundaries and the grain structure of mild steel. Five beams tested were of A-36 steel and of 6 WF 20 rolled section. Central loading was used to develop a plastic tinge at the cent1:1r.

At the center, where a plastic hinge was formed, the effect of the plastic deformations on the grain structure was severe in all the samples taken from the tension side of all plastically or partially plastically loaded beams. In fully plastically loaded beams this effect had spread on both …

Effect Of Internal Pressure On Compressive Buckling Stress Of A Cylindrical Shell Under Eccentric Loading, Chao-Ping Chu

Masters Theses

“In this paper, an investigation was made of a thin- walled cylindrical shell under compressive load with various eccentricities and internal pressures to study the effect of the internal pressure on the compressive buckling stress of the shell.

So far, theoretical methods have not been devised to solve this problem; therefore, an experimental study was carried out. The experimental results indicated that the buckling load of the shell decreases as the eccentricity increases, that the buckling stress increases as the eccentricity increases, and that the change in buckling stress increases with an increase of internal pressure and is very nearly …

Structural Analysis Of Open Channels On Elastic Foundation., Wan-Cheng Liu

Masters Theses

"This study is to analyze continuous open channels used for fluid flow and supported on soil which is considered to provide an elastic foundation. The basic assumption is that the reaction forces of the foundation are proportional at every point to the deflection of the channel at that point. The walls of the channel are considered vertical in all cases but are subjected to various lateral pressures due to different embankment loading conditions"-- Abstract, p. ii

The Effect Of Metallic And Inert Electrodes On The Electrochemical Degradation Of Alkyl Benzene Sulfonate., Thomas Patrick O'Farrell

Masters Theses

"The purpose of this study was to investigate the effects of various metallic and inert electrode combinations on the electrochemical degradation of alkyl benzene sulfonates (ABS) in water and to determine the rate and degree of AB3 removal.

Selected combinations of copper, aluminum, iron, and carbon plate electrodes were studied in systems of tap, distilled and river waters containing an initial ABS concentration of 10 mg/1, using a current density of approximately 0.5 milliamperes per square centimeter and a total detention time of 6 hours. Samples were collected at appropriate time intervals and were analyzed for ABS, chemical oxygen demand …
