Determination Of Unit Weights Of Aggregates In The Laboratory And At The Source, S. T. Collier

Kentucky Transportation Center Research Report

As a result of meetings with producers, a committee of Highway Department engineers recommended that a study be made of various type of aggregates from statewide sources; the objective being to arrive at a standard of evaluating unit weight of aggregates of various but commonly recognized characteristics. It was further desired that a factor be determined which could be applied to a given aggregate for computing its unit weight with reasonable accuracy; taking cognizance of specific gravities and densities as influenced by particle shapes and gradation.

Development, Application And Operating Results Of The Center Peripheral Discharge Rod Mill, David Porter Hale

Professional Degree Theses

"The use of a rod mill for producing manufactured sand is not a recent application. A Marcy Open End Rod Mill has been operating at the plant of the Sun Sand Company, Thayer, West Virginia, since 1925. In early 1940 an 8' x 12' rod mill of the open end type was installed at Shasta. Dam, near Redding, California for sand production. In 1942 work began on Fontana Dam, a Tennessee Valley Authority Project on the Little Tennessee River. The flow sheet included two 9' x 12' high discharge rod mills driven by a single 800 H.P. motor. All of …

An Application Of Skew Frequency Curves To River Stages, Vernon A. C. Gevecker

Professional Degree Theses

"Floods have occurred in the past and will occur again in the future. References to floods are incorporated in some of the early writings of man. Unfortunately though man has recorded the event, he has seldom recorded facts whereby it is possible to determine the volume of flow or the height to which the water rose. Where man has recorded the height to which water rose, much data such as channel conditions, vegetation coverage on the flood plain, etc., remains vague or unknown.

It has been only in comparatively recent times with the advent of the steamboat that man has …

The Potassium Tungsten Bronzes, Ching Hou Ma

Masters Theses

"The tungsten bronzes are a series of substitutional solid solutions of alkali or alkaline earth metatungstates and tungstic oxides. They are not really metallic alloys or intermetallic compounds but they possess some marked metallic properties such as metallic luster, good electric conductivity, high specific gravity, etc. For this reason the name of "bronzes" is applied to them"--Introduction, page 1.

The Development Of Plans For A National Airport For Ankara, Turkey, Mehmet Ragip Samli

Masters Theses

"'The present rapid development of general interest in aviation has brought to the front a new field of engineering. Development of the airplane has already reached a stage where the limit of its usefulness seems fixed only by the places which may be provided for taking off and landing. Due to the newness of the problem, not every one on whom responsibility rests recognizes the fact that the selection of the proper site and location for an airport is just as much an engineering problem as are its design and construction.'

The Turkish government began construction or the Ankara-Esenboga airport …

Relative Productive Value Of Land, Karl Harris, Vaughn E. Hansen

Reports

Location, markets, hard surface roads and other transportation facilities, churches, taxes, schools, and utilities are major factors in the monetary value of land, yet these things do not contribute to the land’s productivity. In this bulletin the only factor considered in determining the agricultural value of land is its productive capacity.

The three major factors in the productive value of land are water, climate, and soil.

These three factors are the principal ones in crop production. If any one of them is unfavorable to plant growth, it can inhibit or even prevent plant growth regardless of how favorable the other …

Safety And Health In Mining, John Philip Lacke

Masters Theses

"The mining industry has long been criticised severely because of its high rate of accident occurrence. Statistics, which, however, are not strictly comparable show that the accident-frequency rate in all mining is currently about three times and the accident severity rate is about seven times as great as the average for general industrial work in the United States. Figures such as these are by no means comforting to mining men. They constitute a challenge to the industry that cannot be ignored.

It must be remembered that any type of mining is more hazardous than most or the other major occupations. …

Effects Of A Reverse Order Of Firing Using Millisecond Delay Electric Blasting Caps In A Quarry Operation, Reginald John Jones

Masters Theses

"Evidence of the steady increase in the production of quarries is a reflection of the improved blasting practices that are being used. New explosives, the new millisecond electrical blasting caps and the endless experimentation carried on by both manufacturer and operator continue to aid or better the old methods of quarry blasting. In many instances the better results were obtained from practices hitherto unknown or at least unused. This report describes the results obtained from comparing quarry rounds shot in the accepted firing order and those shot in the reverse order of firing. The purpose of the report is to …

Calibration Of Weirs By Means Of Critical Flow And Specific Energy, Robert A. Rapp

Masters Theses

"For many years man has been relying more each day upon metering devices to measure the flow of fluids in industry. The orifice, orifice meter, venturi meter, pitot tube, nozzle, flume and the weir have been employed, each having its own particular advantage.

In this parade of metering progress, the contracted weir has long been the forgotten brother of the suppressed weir. In almost every textbook on hydraulics or fluid mechanics, the following words appear, "end contractions are to be avoided where the weir cannot be calibrated". This skepticism and the length or absurdity of some contracted weir formulas led …

Investigation Of The Effect Of Absorption Tower Size Upon Overall Mass Transfer Coefficients, James Robert Murrell

Masters Theses

"The purpose of this research project was to obtain data and determine whether or not a correlation exists between tower size and the overall mass transfer coefficient for a packed tower. A constant ratio of tower diameter to packing diameter of twelve to one was maintained. Three absorption towers were used; a twelve inch diameter iron tower, a six inch diameter iron tower, and a three inch diameter glass tower. One inch, one-half inch, and one-fourth inch Raschig rings were used in the corresponding towers as packing. The system used was the absorption of acetone by water from an acetone-air …

A Determination Of The Economic Feasibility Of Producing Marginal Gas Wells, Horace Tharp Mann

Masters Theses

"The purpose of this investigation is to show that it is economically feasible to produce marginal gas wells in such a manner that all the gas from the edge of the field will be captured by the first row of wells. In this problem the permeability of the sand is to be variable but known, and the effects of this variable permeability on the pressure distribution, and resulting gas production, will be discussed.

In many gas fields the point at which it is generally considered unprofitable to drill new wells is well inside the boundary of the reservoir. This is …

A High-Temperature X-Ray Diffraction Camera And Its Application To Copper And Titanium, Robert R. Penman

Investigation of the thermal dilation of certain cubic metals. 3. Accurate determination of the lattice constant (aₒ) of Beta Titanium at 900 ºC "--Introduction, page 1.

Hydraulic Scale For Measurement Of Dynamometer And Other Forces, John Richard Barton

Masters Theses

"The object of this investigation is to design, build, test, and develop, a hydraulic type scale primarily to be used for measuring dynamometer forces. The scale however is not limited to use on dynamometers, but may be used for other types of force measurements such as the continuous weighing of material on a conveyor belt in conjunction with a recording pressure gage. The scale has numerous applications in determining forces where conventional scales are now used. This particular subject was chosen because of the need for a convenient, inexpensive, and accurate scale for use in measuring the force exerted by …

Effects Of Sand Admixtures On The Physical Properties Of Soils, Necati Kanatsiz

Masters Theses

"The purpose of this study is to determine the effects of sand admixtures on the physical properties of soils. Soil may be defined as a heterogenous [sic] collection of rock and mineral fragments whose decomposition and disintegration have been brought about by the action of physical, chemical, and biological forces, working singly or in combination...In the conviction that the study of soils, with respect to highway engineering, is becoming more and more important this study was undertaken in order to learn whether the addition of sand would lead to desirable results, and if not, at least secure some further addition …

Design And Test Of An Apparatus For Rate Measurements Of Rapid Gas Reactions, Erich Rolaff

Masters Theses

"The present study on rapid gas reactions was initiated with two main goals in view. The first objective was the development of equipment and methods for the treatment of problems arising in extremely rapid gas phase reactions. In recent years, with the advent of large scale applications of gas turbines and rocket motors, the process of high speed gas reactions, especially those of combustion and oxidation have become of increasing importance...The second main goal of the work was to apply the methods and equipment developed to the investigation of chemical systems of interest"--Introduction, page 1-2.

The Temperature Within A Homogeneous Plate Of Finite Thickness, Charles R. Remington

Masters Theses

"The object of this thesis is to determine by an analytical method the temperature within a homogeneous plate of finite thickness subjected to a constant temperature on one side and a periodic fluctuating temperature, expressible in a Fourier series, on the opposite side. This problem in periodic temperature changes has not, to the author's knowledge, been solved previously. The flow of heat in the problem is considered in only one direction, the x-direction. Flow in the other two directions is considered negligible, or zero. Periodic temperature changes in the earth are of importance. The temperature changes have been used by …

The Application Of The Relaxation Method To The Solution Of Steady-State Heat Transfer Through A Concentric Square Insulator, William Edward Simpkin

Masters Theses

"It is the object of this thesis to express the relationship between the heat transfer through a square insulator of variable inside-outside dimension ratios, in terms of a concentric round insulator of the same inside-outside diameter ration, by means of a continuous curve. Mathematically speaking, this thesis will have a plot of a variable coefficient, c_s, to be used...in terms of the ratio of the width of the outside square to the width of the inside square"--Statement of Problem, page 8.

A Study Of Missouri Flint Clay, Edmond Preston Hyatt

Masters Theses

"The problem is one of attempting to explain the peculiar nature of Missouri Flint Clay and to expand the knowledge concerning it. Among the questions for which answers are sought are: What makes Missouri Flint Clay so hard? What happens to Missouri Flint Clay when it is ground? What is the mineralogical constitution of Missouri Flint clay?"--Introduction, The Problem, page 1.

Rockbursts, Christian Maurice Colson

Masters Theses

"This paper does not pretend to originality; it is an attempt to bring to light the causes and the mechanism of rockbursts, as exposed in the literature. Furthermore, an endeavor has been made to give a comprehensive picture of the prediction, prevention, and control methods of rockbursts. Briefly, what has been done in the field of rockbursts, and what remains open to investigation is submitted to the reader. The choice of rockbursts as a thesis subject appears to be justified by the geologic interest of the question. Detailed geologic observations, and particularly the recording of all the structural features which …

Separation Of Cobalt From Zinc Sulfate Solutions By Synthetic Cation Exchange Resins, Wen-Hsiang Chang

Masters Theses

"The purpose of the present research is primarily to investigate the possibility of the separation and recovery of cobalt from zinc sulfate solutions by means of cation exchange resins. It is thought that such an investigation, seemingly of academic interest, might throw some light on determining the possibility of processing some industrial solutions containing both cobalt and zinc. Cobalt, for instance, has been well known as one of the most detrimental impurities in zinc electrolytic solutions. In spite of various purification treatments, small amounts of cobalt are often present in the electrolytic solution, causing a reduction in current efficiency and …
