Geometric and geochemical criteria are studied in detail …

Regulation Of River Bank Development Through Flood Plain Zoning, William James O'Neill

Masters Theses

"The triangular pattern of protection, evacuation and flood plain zoning, as the only truly effective and comprehensive approach to proper flood control, is substantiated in practically all technical publications on this subject by economic and engineering leaders. Yet in actual practice, at the present time, flood plain zoning is not being actively applied by any federal flood control agency and by only one of the forty-nine states faced with this common problem. This lack of direct application was probably best described recently by Walter B. Langbein, Water Resources Division Engineer, U. S. Geological Survey when he said, "Flood Plain Zoning, …

Application Of Statistical Methods To Evaluation Of Mineral Deposits, Francis R. Saupé

Masters Theses

"Only in recent years have statistical methods been applied to evaluation of ore reserves. An attempt is made in this study to prepare an outline to be followed throughout the exploration in order that statistical methods can be applied to valuation problems. Particular emphasis is given to the preliminary requirements to a statistical approach. Representative parameters, sampling pattern, and sample size are discussed in separate chapters"--Abstract, page iii.

Lattice Constants, Thermal Expansion Coefficients And Perfection Of The Phase Tio, Hsiung Wei Li

Masters Theses

"TiO is one of the intermediate phases in the titanium - oxygen system with a crystal structure of the sodium chloride type. The phase extends from about 22 to 29 weight or about 46 to 55 atomic percent oxygen. A comprehensive survey of the physical properties of the phase has been made in previous investigations (see review of literature), but only impure titanium was available at that time. Therefore, some revision of the measurements had to be made. Also, neither the thermal expansion coefficients nor the temperature at which the lattice constants were measured were reported.

For precision determination of …

A Preliminary Investigation Of Natural Gas Combustion As Applied To Thermal Recovery Of Petroleum, Roger J. Schoeppel

Masters Theses

"Present application of the subsurface combustion processes in the thermal recovery of petroleum afford favorable and opportune methods of providing greater recoveries from petroleum reservoirs. This study attempts to elucidate some of the parameters controlling the complex hydrocarbon oxidation for one such process. The experimental phase consisted of investigating the combustion behavior of eight nonexplosive and one explosive natural gas-air mixtures at low and intermediate pressures. The hydrocarbon was allowed to oxidize by self-ignition under controlled conditions within environments precluding a visible flame type reaction. Progress of the reaction was followed by measuring effluent oxygen content.

Experimental evidence indicate the …

Design And Construction Of An Automatic Antenna Pattern Plotter And Design Of A Microwave Absorbent Material, Norval D. Wallace

Masters Theses

"The following study consisted of two problems. One was the design and construction of an automatic antenna pattern plotter, and the other was the design of a microwave absorbing material for use in a darkroom"--Introduction, page 1.

Steady State Temperature Distribution In A Rotating Disk, George Henry Morgan

Masters Theses

"The purpose of this investigation was to obtain an expression for the steady state temperature distribution of a disk of uniform thickness rotating at a constant speed in ambient air while absorbing heat through the periphery at a constant rate. Engineers encounter such problems in connection with brakes of several varieties. The general solution obtained here could be extended to similar physical problems such as grinding wheels, disk clutches, and so on.

A differential equation was obtained for the temperature in the disk by the application of Fourier's conduction law and Newton’s convection law. A solution of this equation was …

Effect Of Alkaline Earth Chlorides On Vapor-Liquid Equilibria Of Acetic Acid-Water System, James F. Carnahan

Masters Theses

"In the separation of a system of liquids by distillation the ease with which they may be separated is most clearly indicated by the relative volatility; the greater the value of the relative volatility, the greater the ease of separation.

A system that contains compounds whose boiling points are spread over a relatively small temperature range is not readily separated by distillation. The addition of a substance that reduces the vapor pressure of one of the components, while having little or no effect on the others, adds to the ease of separation and consequently would decrease the initial size and …

The Effects Of Ultrasonically-Induced Cavitation Upon Dissolved Oxygen, Free Carbon Dioxide, And Bicarbonate Ion Concentration In Water, Charles Alvin Wentz Jr.

Masters Theses

"Cavitation may be encountered in many scientific fields. Mechanical and civil engineers are concerned with the prevention of cavitation erosion in the design of turbines, propellers, underwater missiles, and similar structures. Biologists and physiologists are seeking more knowledge concerning the tensile strength of liquids, such as, tree sap and the formation of gas bubbles in the blood stream. Finally, the physicist and acoustical engineer must cope with the cavitation problem when working with underwater transducers, cavitation noise, and the propagation of acoustical signals through media in which cavitation is occurring.

There are many forces which hold a liquid together and …

Chemical Kinetics Of The Zirconium-Hydrofluoride Reaction, Wayne G. Custead

Masters Theses

"It has been only in recent years that hafnium-free zirconium has been made available for commercial use. When economical methods were developed in 1950 to remove hafnium from zirconium, a metal was produced which not only exhibited good corrosion resistance and desirable physical properties, but which also had a very low absorption cross section for thermal neutrons. These factors have led to its most important application to date, that of a structural material for nuclear reactors.

The outstanding non-nuclear property of zirconium is its corrosion resistance to most mineral acids. Hafnium-free zirconium exhibits outstanding resistance to all mineral acids with …

Evaluation Of The Force Constants Of Non-Polar Gases From Viscosity Data, Charles Warren Keller

Masters Theses

"Studies of the intermolecular forces and potential energy functions have been largely of a theoretical nature. Various empirical statements representing these theories have been developed and tested. Of these, the Lennard-Jones (6-12) potential is one of the more realistic and has become the most favored when dealing with non-polar molecules.

The values of these “force constants” or the values of the Lennard-Jones (6-12) potential parameters, have been determined from both diffusion and viscosity data. Although these “force constants” can be determined from diffusional measurements as well as viscosity data, the literature is predominately filled with values of force constants which …

Linear And Vortex Flow Heat Transfer Coefficients, Edward Robert Schmidt Jr.

Masters Theses

"In order to make possible better, more efficient equipment, a higher and higher rate of heat transfer has been the goal of engineers for many years. The need for heat transfer rates never thought of 25 years ago has been brought about by the advent of modern high-performance devices such as nuclear reactors and rocket motors. "A heat release of about 40,000 Btu/hr.cu.ft. is considered good practice in a modern boiler, but in a rocket or a nuclear reactor it may be 1,000,000,000 Btu/hr.cu.ft." This heat must be removed by transfer to a coolant or converted into work or the …

The Vapor Pressures Of Pbo-Sb₂O₃-Sio₂ Mixtures., John Henry Smith

Masters Theses

"The removal of antimony is one of the important steps in the production of pure lead. The process of removing antimony from impure lead bullion is called "lead softening". The most common method used is to blow air into a bath of impure molten lead. The impurities, primarily antimony, arsenic and tin, if present, are oxidized and form a slag or "dross" which floats on the surface of the lead bath. A considerable amount of lead is oxidized in this step and joins the other oxidized compounds in the dross. This dross is skimmed from the bath of molten lead …

A Comparison Of The Effect Of Pvt Data Application Methods On Predicted Depletion Drive Reservoir Performance, Frederick A. Klein

Masters Theses

"It is generally agreed that the evolution of gas from oil within a reservoir is most closely approximated by the differential liberation process, while gas liberation in the flow string, surface separator, and stock tank is most nearly represented by flash liberation. To conform with this assumed physical behavior, appropriate application of both flash and differential liberation data in the computation of reservoir performance by material balance methods is indicated.

In this work, simple depletion-drive oil and gas recoveries were calculated (1) using differential liberation data only, and (2) using differential liberation data adjusted to incorporate the results of flash …

300-Kilocycle Ultrasonic Emulsification Of Paraffin Oil In Distilled Water, John Henry Rother

Masters Theses

"Emulsions have been in existence for thousands of years in the form of cosmetics, food, and medicines. Emulsions cover a vast number of products in both household and industrial use. Homogenized milk, butter, mayonnasise, salad dressing, and sauces are emulsions that are used every day at the dinner table. Medical salves, ointments, cosmetic creams and many other pharmaceuticals are used every day by members of both sexes in the human race. Waxes and polishes for automobiles, metal, floors, leathers, and furniture are emulsions. All of the new so called "wonder paints" and "rubber-base paints" are nothing more than an emulsion …

X-Ray Diffraction Study Of The Metal Powder Compacts, Rajendra Sharan

Masters Theses

"Various theories have been put forward about the mechanism of compacting and sintering processes. None of these theories are confirmed. The reason is that most of these theories are based on observations on metallographic specimens, which is not a particularly good tool for such a study. Little data using xray diffraction analysis is available and there seems to be a great need of making a thorough investigation in this direction.

The main object of this investigation is to study xray diffraction patterns of green compacts of aluminum, nickel and copper powders pressed under different compacting pressures to see if any …

The Effects Of Fly-Ash On Dynamic Modulus Of Elasticity Of A Concrete Mortar, Bill L. Atchley

Masters Theses

"Over the last few years an increasing amount of interest has been shown in the use of prestressed concrete. As is true in many new methods of design or construction, the properties of existing materials to be used sometimes fail to meet all the desirable characteristics, and certain modifications might be advantageous. This is certainly true of prestressed concrete design and construction, in which a lower modulus of elasticity accompanied by a minimum loss in strength would be desirable. If a lower modulus of elasticity could be obtained for concrete, a lower prestressing load could be used and still maintain …

A Review Of Fossilization Processes In Different Sedimentary Environments (With Special Reference To The Time Factor Of Deposition Of Ore Minerals Associated With Fossil Material, In Particular The Coprolitic Phosphate Deposits), Giovanna Reggiori Ligasacchi

Masters Theses

"This thesis offers a cross/section through some principal fossilization processes involving organic matter (animals and plants) during and after sedimentation. The influence of different environments during fossilization is considered. The chemical composition of some classes of living invertebrates and plants is compared with the chemical composition of same organisms as found in consolidated sediments as fossils.

Some literature on carbonates, oxides, silicates, phosphates, and sulphides in fossils is reviewed with particular attention to those instances where the fossils are associated with ore minerals. Special consideration is given to the occurrence and composition of fecal matter in recent and consolidated sediments. …

Stabilization Of Swelling Clay Soil By Additions Of Calcium Hydroxide And Calcium Oxide, Anthony Diler

Masters Theses

"As a study of all types of stabilization would be very lengthy, it was decided to make the object of this research the determination of the effect of the addition of different percentages of calcium oxide (CaO) and calcium hydroxide Ca(OH)₂ on the physical characteristics of a silty swelling sodium montmorillionite clay. The purpose of this addition is to flocculate the clay by utilizing a base exchange between the sodium and calcium ions, and thus change the physical characteristics of the soil. The soil by itself has the characteristics of a fat clay, that is it can be broken …

Imperfections Within Ti₂O₃ And Tio₂ Phases In The Titanium-Oxygen System, Tatsuhiko Ejima

Doctoral Dissertations

“The hexagonal-rhombohedral Ti₂O₃ phase in the Ti-O system extends from 32.5 to 34.5% oxygen b.w., with the exact composition of Ti₂O₃ nearly in the middle of the phase. Seven samples of different composition within that phase were made, and the lattice constants (a and c) and the density of each sample were determined.

The plots of the constants against the composition of the samples revealed a deviation from Vegard’s rule when approaching the exact composition of Ti₂O₃. The lattice constants of this compound, obtained by graphical interpolation were; a_{25 …}
