An Equilibrium Study Of The System Bi-S-H₂, Don Hie Lee

Masters Theses

"An experimental study has been conducted to determine the equilibrium behavior of the system Bi-S-H₂. The system was studied by equilibrating H₂-H₂S gas mixtures with Bi(l)- Bi₂S₃(s) two-phase mixtures at temperatures of 500°, 600°, 700° and 750°C in a circulating type equilibrium apparatus. The equilibrium gas mixtures were analyzed by a Fisher Gas Partitioner with a reproducibility of approximately 0.06 %.

A linear free energy equation has been derived from the results with an average deviation of ± 1 Kcal. This deviation is well within the accepted experimental accuracy for …

A Simplified Method Of Estimating Drilling And Blasting Costs Of A Highway Through-Cut Excavation In Rock, Donald J. Roberts

Masters Theses

"The development of cost estimating methods has been the most neglected phase of highway engineering. Overlooked in particular has been the development of an easily understood and easily applied method of estimating the costs of the drilling and blasting operations involved in a highway through-cut excavation in rock.

This investigation developed such a method by adapting and applying recent developments in the blasting planning field. The study was limited to small diameter blastholes and excavations in lifts of less than thirty feet. Normal efficient construction practices were presumed.

It was found from the investigation that the blast geometry and, subsequently, …

Separation Of Radioactive Fission Products By Electrodialysis Using Aminopolycarboxylic Acids., Harry C. Hershey

"The development of nuclear fission reactors to convert nuclear energy into electrical energy for use in industry, public utilities, military applications, and space exploration has resulted in ever increasing quantities of radioactive waste solutions. Significant reductions in nuclear fuel costs will be obtained when economical processes have been developed for recovery and purification of valuable fission products which are contained in radioactive waste solutions and are in demand for many research applications.

The United States Atomic Energy Commission has supported exhaustive studies to recover fission products by processes involving the more common unit operations such as extraction, distillation, crystallization, and …

Analysis Of Problems In The Performance Of A Natural Gas Storage Reservoir., Gerald Eugene Henderson

Masters Theses

"A digital computer technique is presented for predicting two parameters of underground natural gas storage reservoir performance: (1) the prediction of reservoir pressures and volumes, and (2) the prediction of optimum flow rate and pressure drawdown for a single well in accordance with the theory of water coning.

The outlined procedure for predicting gas storage reservoir pressures and volumes was not effective for the field studies, although certain conclusions have been drawn which should be beneficial in further studies.

The procedure for predicting optimum gas flow rate and pressure drawdown from a well without production of bottom water involved first …

Determination Of The Standard Free Energy Of Formation Of Zr₃S₂, Peter E. Otten

Masters Theses

"The Knudsen effusion method was used to find the equilibrium magnesium pressure for the reaction

3 Zr (s) + 2 MgS (s) = 'Zr₃S₂' (s) + 2 Mg (v)

By using known standard free energy data for the formation of magnesium sulfide and by using the equilibrium magnesium pressure, the standard free energy of formation of Zr₃S₂ was calculated and could be expressed by the equation

Δ F° = -139,800 + 49.13 T cal/mole

in the temperature range 900 to 1100°C.

It was also found that Zr₃S₂ was the zirconium …

The Justification For And Design Of A Lunar Radio Observatory., Thomas Van Doren

Masters Theses

"The purpose of a radio telescope is to record information concerning the strength, spectrum, polarization, and direction of arrival of extraterrestrial electromagnetic radiation at radio frequencies. Earthly based radio observatories are hampered in their attempt to achieve this purpose by atmospheric absorption and reflection of the radiation. A lunar based system would not have this problem because the Moon possesses practically no atmosphere. However, other environmental conditions, such as micrometeorites, high frequency radiation, and extreme temperature variations, must be overcome. This thesis justifies the need for a lunar radio observatory and also describes a particular radio telescope system which should …

The Electrochemical Degradation Of Alkyl Benzene Sulfonate., Melvin David Rickard

Masters Theses

"The ever increasing use of nonbiodegradable synthetic detergents, mainly the alkyl benzene sulfonates, has created difficulties in water and wastewater treatment, and in stream pollution. Although considerable attention has been given to this problem, no solution has been developed which can be effectively employed in the abatement of detergent pollution.

The purpose of this investigation was to determine the feasibility of the use of direct current electrochemical degradation in the removal of alkyl benzene sulfonates (ABS) from water. The rate and degree of completion of the electrochemical reactions were determined, and the nature of the end products formed was investigated. …

Missouri School Of Mines Antenna Range Design., Russell Melvin Ousley

Masters Theses

"The problem was to design, construct and evaluate an antenna range which could be used in future research and instructional programs. The basic theory of range design and practical considerations were studied and a range was then designed and built from equipment which was either immediately applicable, applicable after modification or constructed to fit the needs of the range. Tests were made to determine the performance characteristics of the system with respect to the more important design parameters. Suggestions were given for future improvement of operation and expansion of the range capabilities"--Abstract p. ii

Digital Computer Design Of Compensation For Linear Control Systems, Larry C. Amsler

Masters Theses

"If a control system is to be synthesized, it is inferred that a plant or process is present which must be controlled, and the problem of how to design the control system then arises. The first step is to decide on performance specifications to which the complete system must conform. These specifications may involve such things as the system steady state response, transient response, or frequency response. Any of several synthesis methods may then be applied to complete the system design.

In this study a synthesis method is developed for single-loop linear feedback systems. First, the number of compensating poles …

Some Effects Of Impact Of Low Magnitude On The Deformation Of Prestressed Gypsum Cylinders., Arthur Joe Bush

Masters Theses

"A review of the literature pertaining to the subject is presented. Many series or impacts were made on specimens of gypsum which were already under a static load. A special. repetitive impact machine was used to allow a variety or weights to fall from predetermined heights. Tests were conducted inside a roan constructed especially for these tests. Heat gained or lost through the ceiling and walls was kept at a minilI1um by a lining or aluminum-covered, fiber glass insulation. Temperature and humidity conditions were kept nearly constant by a combination air-conditioner and dehumidifier.

Repetitive loading of the prestressed specimen was …

All of the deformations were obtained using a constant explosive charge consisting of a #6 commercial blasting cap coupled with a commercial chemical booster"--Abstract, page ii.

Thermocouple Shape Influence On Response In A Dynamic Compressible Fluid Atmosphere, Philip J. Steger

Masters Theses

"This investigation was performed to determine whether the geometrical shape of a thermocouple used to measure the temperature of a dynamic fluid atmosphere had any affect on its recovery factor and time response.

A converging nozzle was used to establish a dynamic fluid stream in which shaped silver solder junctions of copper-constantan thermocouples were tested. The velocity of the working fluid, air, was about 1000 ft/sec at the test point.

The investigation was successful, within experimental limits, in determining that the recovery factor of a bare thermocouple junction is not influenced by geometrical shape The results agreed substantially with available …

Construction Report On Experimental Use Of Natural, Bituminous, Quartz Sandstone (Kentucky Rock Asphalt) As A Traffic-Bound Aggregate, George R. Laughlin

Kentucky Transportation Center Research Report

Major deposits of natural, bituminous, quartz sandstone (Kentucky Rock Asphalt) occur in six counties of western Kentucky and a few minor deposits occur in eastern Kentucky. Crushed rock asphalt has been used extensively in Kentucky and elsewhere for over 50 years for surfacing roads.* The most productive area was in Edmonson County where the Caseyville and Bee Springs formations were quarried and mined. These deposits have been described as oil-pools which are now defunct and from which only the asphaltic residue remains. The bitumen content of the rock varies locally in a quarry or mine; and, because of this, enormous …
