Was Assimilation Important In The Formation Of The Boulder Batholith?, Richard Marvin

Bachelors Theses and Reports, 1928 - 1970

Examination of a rock suite from the northern end of the Boulder batholith reveals that four of the eight criteria for assimilation as given by Grout are present. Thus, in the opinion of the writer, there is evidence and trends to signify assimilation, but no indication of the importance that it played in the formation of the Boulder batholith.

The Bighorn Mountains, The Little Rocky Mountains And The Bowdoin Dome Uplifts, E. J. O'Connell

Bachelors Theses and Reports, 1928 - 1970

The purpose of this paper is to secure an actual figure describing the amount of uplift in the Bighorn Mountains, the Little Rocky Mountains and the Bowdoin Dome. To the writer’s knowledge, the amount of uplift in the areas mentioned has not been determined before. Such a figure could be useful in structural studies of Montana and Wyoming, because the amount of uplift is a fair measure of the intensity of orogenic forces; also, the amount of uplift is a prerequisite to the determination of the amount of erosion.

Drainage By Pumping In The Lewiston Area, Utah, Paul J. Pehrson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In irrigated areas it often becomes necessary to provide means by which the excess water may be removed. After a period of time if these drainage provisions are not made, it may become necessary, because of the saline soils or water logged condition that may develop, to abandon the land for agricultural purposes.

The increases of irrigation on the higher lands in Utah has resulted in an increased need for drainage on much of the lower land in the valleys. This increased need for drainage has long been recognized and in 1947 it influenced the Utah Agricultural Experiment Station, in …

Consumptive Use Of Water Studies In The Ashley And Ferron Creek Areas Of Utah, Elden E. Fisher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The inadequacy of water and power supplies in Utah for agriculture, for industry, for domestic and community consumption has retarded the State's economic growth. Shortages of water and hydroelectric power are the principle impediments to the full realization of other potentials of Utah, that is, the full use of its arable lands, the wide and diversified use of its industrial raw materials, and the unrestricted development of its communities. The problem of securing additional sources of water and power has resolved itself into one of major concern. The objective of this study was to determine unit values of consumptive use …

Experimental Studies Of The Effect Of Moisture On Strength Of Mine Roof-Shales, Rolf W. Roley

Professional Degree Theses

"The mining and production of coal by underground mining operations has long been recognized as one of this nation's most hazardous industries. Tabulated data from the State of Illinois, for example, reveal that in that State between 1882 and 1945 there have been 7,789 men killed in coal mining accidents of one form or another. Further inspection of the data indicates that 3,711 of these men were killed underground by falls of roof or rock….

As previously stated, this experiment was designed to determine whether or not any appreciable change in strength as measured by Transverse Breakage would result from …

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 …

Analytical Investigation Of Bending Effects On The Stability Of A Tube Subjected To External Pressure, Charles Young

Masters Theses

"The behavior of thin and moderately thick-walled tubes under various types of loadings has been a major problem of several leading industries for many years. Predominant among these, and the one for which this thesis was primarily undertaken, is the oil industry. The problem attacked in this thesis, however, is not limited to that industry alone, having ample application in industries that are sub-marine in nature, or any industry in which the application of external pressures on equipment is likely to be responsible for buckling failures...In this thesis, the problem of finding the effect of bending on the collapsing pressure …

The Volatility Of Metallic Sulfides And Their Treatment By Vacuum Metallurgy, Chi-Mei Hsiao

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 …

Principles And Practices Controlling The Use Of Earthmoving Equipment, Woodrow John Latvala

Masters Theses

"The purpose of this study is to show how the efficiency in earthmoving projects can be increased by the application of engineering principles. Efficiency can be increased by choosing equipment to fit the given set of conditions; and, having chosen the equipment, operate it at its maximum efficiency. In order to choose the right equipment it is necessary to study the conditions under which the equipment must operate. It is then necessary to study the machine in order to ascertain its adaptability to the existing conditions"--Introduction, page 1.

The Economic Spacing Of Contraction Joints In Reinforced Concrete Pavements, Wilbert Frederick Wegener

Masters Theses

"Structurally, there are two types of joints used in concrete pavements: (a) the tied, or permanently-closed joint; and (b) the open or free type of joint. The permanently closed joint utilized tie-steel of some form to keep the joint from opening. Usually, this steel is in the form of short individual bars extending across the joint and bonded to both slabs (designated as "tie-bars") or in the form of distributed reinforcement. The remaining method of classification, that of refering [sic] to the joint purpose, gives the expansion joint, contraction joint, and warping joint. An expansion joint is, as the name …

Efficiency Studies Of The Effect Of Moisture On The Power Consumption Of Mine Scrapers, Georges J. Vigier

Masters Theses

"Many years of practice have resulted in the standardization of several types of scrapers which are now commonly manufactured for use in mining. Although experience has brought out much information on scraping operations, no systematic studies of the efficiency of mine scrapers have been carried out before the experimental works done in the last few years at Missouri School of Mines and Metallurgy. "Purpose of Problem": The purpose of this present study is to consider the effect which moisture in the muck has on the efficiency as regards power consumption and amount of material scraped, of different types of mine …

Calculations Of Maximum Sag Of A Transmission Line With An Ice Load On One Span, Rodney A. Schaefer

Masters Theses

"An important problem concerning electric power lines is the calculation of the maximum sag occurring when there is an ice load on only one span. The object of this thesis is to determine a practical method for calculating the maximum sag of a transmission line, suspended on suspension insulators, with the aforementioned loading conditions. This paper is limited to the case where the supports of the transmission line are at equal elevations and all span lengths are equal"--Introduction, page 1.

Economical Span Length Ratios For Three-Span Continuous Girder Bridges, Donald Hindrik Timmer

Masters Theses

"The three-span continuous bridge is one of the most popular bridges used by highway departments at the present time. The low first cost and overall economy combined with the pleasing appearance of this type of bridge as compared to simple span structures has led most highway departments to use continuous spans whenever conditions permit. The design of three-span continuous bridges, as well as the design of any of the other bridge types, is usually carried out as an analysis rather than a design. In the case of the three-span continuous girder, with rolled steel beams, an initial assumption as to …

A Study Of Mine Scraper Efficiency On Materials Of Different Specific Gravities, Kermit Guy Rowley

Masters Theses

"The purpose of this study is to determine the effect that the specific gravity of the material scraped has on the power consumption and the efficiency of the common types of mine scrapers. As scraper weight, rope speed, and moisture content of the muck are important factors affecting the power consumption and efficiency, these variables are the ones considered for each type scraper. Two materials of different specific gravities are used in the study with an equal number of tests run on each material"--Introduction, Purpose of Problem, page 2.

A Study Of The Efficiency Of Split-Second Delay Electric Blasting Caps In Underground Limestone Mining, John B. H. Fitzwilliam

Masters Theses

"The introduction of electric blasting caps have delay intervals of the order of one-half to one second proved of advantage in many aspects of underground mining, particularly development work. Their use spread, until they now supersede fuse-and-cap firing wherever possible. Split-second delay electric blasting caps are a comparatively recent development from conventional delay caps. They have been found of practicable use in quarrying operations, and have been applied in many phases of underground mining. While evidence, to show that short-delay firing in quarrying is more efficient than instantaneous firing, is becoming increasingly conclusive, it remains to be proved that split-second …

The Study Of Effect Of Definite Grain Sized Sand On The Shearing Strength Of Clays, Faruk Omer Akkoseoglu

Masters Theses

"Slopes of all kinds, including mountains, hills, sea coast bluffs, river banks, and man made cuts and fills, stay in place only because of the shearing strength possessed by the soil or rock of which they are composed. The resistance of soils to shearing strength is probably the most important of all the soil properties to foundation engineers. Most of the serious structural failures which are due to unexpected soil behaviour are caused by deficiency in the shearing strength of the soil. Water, on the other hand, possesses no static strength in shear, therefore bodies of water have no surface …

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 …

A Comparative Study Of Some Rock Drill Bits, Charles Roger Knopp

Masters Theses

"The detachable single-use rick-drill bit has attracted considerable attention in the mining industry of the United States during the past few years. While this type of bit has been used for some time in other countries, it has been only recently that these bits have been manufactured in the United States. It was decided to test this type of bit and make a comparative study of a single-use bit and a widely used detachable rock-drill bit"--Introduction, page 1.

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 …

The Theory Of Limit Design As Applied To Column Analysis, John Francis Mccarthy

Masters Theses

"In any discussion of compression members of a structure, account has to be taken primarily of the relative "slenderness" or bending weakness of the member. If the member be so short that axial loading causes very slight deflection at any point throughout the member, it is usually designated a simple compression member and no account is taken of the additional stresses due to the deflection. When, however, the ratio of the length to the least radius of gyration of the member becomes so large that bending stresses cannot be ignored, the member is usually called a column and its consequent …

Periodic Heat Flow In A Semi-Infinite Solid, Warren George Heidbrier

Masters Theses

"The object of this investigation is to determine by analytical means the temperature within a homogeneous semi-infinite solid, as a function of time, while the solid is receiving heat periodically by radiation on its one flat surface. Periodic heat flow means that heat flow is a continuous function of time and repeats itself at regular intervals. A semi-infinite solid has only one bounding plane and extends to infinity in all other directions...Much of this work deals with the soil temperatures of the earth both at the surface and at various depths. The surface of the earth is subjected to daily …

A Study Of Cast Eutectic Structures By Means Of Optical And X-Ray Microscopy, John Stanton Winston

Masters Theses

"The present research is the result of interest in two rather broad, and at first thought, seemingly entirely separate topics: the structure of eutectics and x-ray microscopy. D. Hanson in 1923 in his correspondence with Albert M. Portevin in regard to his article on the structure of eutectics states, "A point that always stuck him (D. Hanson) in examining eutectics was that one of the constituents always formed a continuous phase round the other one. The orientation of one constituent was either constant or varied in a uniform manner. What, however, was the condition of the 'enveloped' constituent, which formed …

Velocity Studies In A Vertical Pipe Flowing Full, Robert Franklin Tindall

Masters Theses

"The purpose of this investigation is to install a hard drawn copper pipe approximately 1/2 inch in diameter, and approximately 35 feet long in a vertical position. The copper pipe is to have pressure takeoff points at various distances along the length of the pipe. The purpose of these takeoffs is to measure the pressure of the water at the point of takeoff in the pipe. The water is to be forced into the pipe, assisted by gravity, thereby causing a pressure of some measurable quanity [sic] greater than absolute zero pressure. The discharge was to be by volumetric measurement, …

An Experimental Study Of Crystallization In Opal Glass, William C. Rous

Masters Theses

"Opal glasses are well known from use in such forms as ointment jars, lighting globes, wall panelling [sic], and decorative effects in glass vases. Cryolite, fluorspar, and sodium fluosilicate are used in varying proportions in most glasses of this type. Since little is known of the mechanism of crystallization in opal glass, there is a definite need of gathering further information on this subject. This information is of particular interest to the manufacturers whose products consist of this type of glass. Further information would aid in control of the characteristics desired and perhaps would allow a more economical control"--Introduction, page …

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.
