Geological Report Of Conrow Wood Creek Area 8 Miles N.E. Of Whitehall, Montana, Kenneth M. Judd

Bachelors Theses and Reports, 1928 - 1970

Plane table and pacing methods were used in the mapping of the individual areas, but an automobile traverse was used to tie the independent areas into a composite group that would be useful for the entire zone. All land marks, section corners, roads, fence lines, drainage, and geologic features were plotted in the field and later transferred to a master map.

Interrelationship Of Transverse Anchorage And Adhesive Bond In Welded Wire Reinforcement, Alan Arthur Becker

Masters Theses

"...Welded Wire Reinforcement Fabric has been applied only to certain "light types" of reinforced concrete construction. It has not as yet been applied as main tension reinforcement for most concrete structures, mainly due to the fact that a thorough investigation of the potentialities and possibilities of welded wire fabric has not as yet been conducted. It is expected that the data collected in this investigation coupled with data collected in similar investigations performed at the Missouri School of Mines and Metallurgy will furnish the basis for a structural and economic comparison between welded wire fabric and ordinary reinforcing bars. The …

Masters Theses

"Since the author has always been interested in Aeronautical Engineering, and in particular, rotary-winged-aircraft, the problem of research for aerodynamic improvement of rotary-wing control systems was chosen. This problem was suggested by the Army Aircorps Officials of Wright-Patterson Field of Dayton, Ohio as being a valuable and practical problem for the government. It is also valuable and practical for the author since it follows his general course of undergraduate study and since it fits closely into the field for which he is preparing himself...The requirement with which the author is most concerned is the design system for the producing of …

Design Of A Wind Tunnel For The Missouri School Of Mines And Metallurgy, William E. Speece

Masters Theses

"For some time there has been a need for a wind tunnel at the School of Mines for experimental work in the Civil and Mechanical Engineering Departments. With the expanding program and the possibility of establishing an Aeronautical Engineering School here, the need will be even more pronounced. So the problem will be of definite practical value. It was the original idea to design a small tunnel, build the tunnel, and to run a series of smoke tests on various structural models. However, after discussing the possibility of such a problem with school authorities, it was decided that if a …

Efficiency Of Various Types Of Reinforcement In Controlling Opening Of Cracks In Concrete Pavements, Frederick Richard Heartz

Masters Theses

"To date very little work has been done on the subject of the amount of crack opening for different loads on concrete pavement. It is a known fact that these cracks must be held together sufficiently to have aggregate interlocking action if the pavement is to transfer loads from one edge of a crack to the other. The maximum permissable [sic] opening has been set at .027 inches by the Highway Research Board. The author has attempted in this investigations (1) to determine the effect of different spacing and different sizes of longitudinal and transverse wires in controlling crack opening …

Analysis Of The Transit Traverse Survey Method Of The United States Department Of Interior, Geological Survey, Edward John Kimmick

Masters Theses

"This thesis was undertaken to ascertain the feasibility of incorporating the United States Geological Survey methods of surveying and computing into a course of study in the Civil Engineering curriculum. It has been the author's opinion that a course of study could be tendered, as a definite project, which incorporates fundamental surveying and advanced surveying. The author's planned course of study was a method of third order transit traverse survey streamlining the method used by the United States Geological Survey. The time element and weather were the essential factors in the planning. In the advanced surveying course there are eighteen …

The Theory Of Limit Design As Applied To The Design Of A Continuous Beam Over Three Supports, Robert F. Davidson

Masters Theses

"The theory of Limit Design is the application of the theory of Plasticity to the estimation of the actual carrying capacity of a structure. In this theory, as it is applied to statistically indeterminate structures, the areas of most unfavorable stress are allowed to be stressed beyond the yield point and into the plastic range of stress. It was formerly held that, by assuming elastic behavior, all questions of strength of materials that concern the Structural Engineer were capable of solution. However, it is now becoming recognized, from actual measurements of deformations of structures and from tests carried to near …

An Economic Comparison Of Short Span Bridges, Glenn B. Armstrong

University of the Pacific Theses and Dissertations

Present day culture is based upon physical goods and the benefits derived from them. stemming from this physical culture is the desire of possession. Since it is impossible for one person to posses everything, the desire is translated into potential possession. That is, the acquisition of a type of goods that can be exchanged for any other goods at the desire of the individual. This potential goods in money. Thus it becomes the chief sin of every person to acquire money. In order to accumulato a supply of money, an individual must no combine the three factors of production, land, …

A Study Rigid-Frame Design Versus Truss-And-Column Design, Stephen H. Goodman

University of the Pacific Theses and Dissertations

This paper describes the investigation of a mill building bent of truss and column design, a redesign using a rigid-frame, and an estimated cost of each design. For sake of brevity the overall design of the building (sway bracing, lateral bracing, purlins, girts, roofing, siding, and bay spacing) was assumed to be the same for both designs. It is possible that this assumption cannot be made and the estimates of cost, therefore, are in error. In actual practice the complete redesign of the building should be considered.

Recommended Procedure For The Computation Of Rights Of Way, Leon Hershkowitz

Professional Degree Theses

"This thesis sets forth a recommended procedure for the computation of areas included in "rights of way," using the principle of double meridian distances.

For a considerable number of years, it has been the opinion of the author that steps should be taken to arrive at some form of standardization in the procedures necessary in the computation of areas involving right of way and to more or less standardize legal descriptions pertaining thereto.

One need only examine the records of the various County Recorders in one particular state or in different states and he would be entirely convinced that such …

Research Investigation Of Seepage Control For Dams And Levees, Robert Raymond Brookshire

Professional Degree Theses

"The problems of a century old levee system have provided excellent research for the Corp of Engineers and others in the design and construction of earth dams for flood control, navigation and multi-purpose projects. A special problem on which valuable knowledge has been gained is that of seepage control. The experiences obtained in recent years have been supplemented by theoretical developments in the field of soil mechanics, but it is believed that considerable information will be gained on seepage control from further investigation and experience.

The safety factor to prevent failure from seepage is believed to be the most critical …

A Correlation Of Formulas For The Flow Of Fluids In Pipes, John Gorman Duba

Masters Theses

"At present there exist two quite distinct fields in fluid flow in pipes, the one in water supply and the other in the petroleum industry. It is the purpose of this paper to discuss the various pipeline flow formulas as used in both fields and to correlate the exponential type formula which is much used in practice with the Nikuradse curves obtained in the laboratory"--A Brief Historical Review, page 5.

Geologic Considerations In Relation To A Materials Survey, James L. Young Jr., L. E. Gregg

Kentucky Transportation Center Research Report

In materials surveying, geology should be of maximum benefit, not as a complete informant but as a foundation for reconnaissance, assembly, and cataloging of materials. Geology in essence is a materials survey on a grand scale. Use of this science for engineering purposes involves some primary knowledge of geologic nomenclature, the basic historic approach of geologists, and the use of resources and data published by state, federal, and private agencies over a period of 75 years.

Recognition of the need for information on surface conditions as an aid to engineering and allied sciences is emphasized; and in response to this …

The Establishment And Analysis Of A Triangulation System For The Teaching Of Advanced Surveying, Philip Blaine Newlin

Masters Theses

"The first thought of establishing a triangulation system for the University of Arizona student work was conceived early in the fall of 1947, when the author first learned that he would be in charge of the advanced surveying field parties during the spring semester. These men were to be instructed in the accepted manner of conducting surveys of higher order. This would include the measuring of a base line of second or first order accuracy, the turning of horizontal angles with this same degree of accuracy, the determination of the azimuth of the lines by astronomical observations, the running of …

A Laboratory Investigation Of Mineralogical, Chemical And Physical Properties Of Limestone Aggregates, James L. Young Jr., James H. Havens, L. E. Gregg

Kentucky Transportation Center Research Report

The project described in this report represents one phase of comprehensive research with all types of aggregates for highway paving mixtures in Kentucky. It was designed to show the fundamental properties of limestones which determine their suitability for this type of use -- particularly their so-called durability. For this reason, emphasis was placed on analysis of the intrinsic properties of the aggregates themselves rather than analysis of procedures or test methods, such as freezing and thawing.

Separation, Fractionation And Mineralogy Of Clays In Soils, James H. Havens, James L. Young Jr., Robert F. Baker

Kentucky Transportation Center Research Report

This paper describes a working method for separation, fractionation and identification of colloid and colloidal clay minerals in soils. Technical information pertains to super-centrifugation, electron-microscopy and X-ray diffraction. On the basis of these techniques, twenty-two samples have been investigated in conjunction with a soil stud of pumping pavements.

Soils were first dispersed and separated by gravity sedimentation. Fractionation was accomplished by controlled super-centrifugation. The separated fractions were purified and then analyzed by X-ray diffraction. Computed size fractions were checked by shadow castings and lineal dimensions on electron micrographs.

Results include identification of the mineral or minerals present and the properties …

Tests On Cold Formed Steel Studs For The American Iron And Steel Institute, American Iron And Steel Institute

CCFSS Library (1939 - present)

1. SCOPE OF THIS REPORT. In connection with a prospective revised Second Edition of the Specifications the question has been raised as to the reliability of Section 3.7, Combined Axial and Bending Stress. This stipulation at the time wa.s adopted from the AISC Specifications without detailed investigation. It appeared pertinent, therefore, to subject this requirement to a detailed analysis for purposes of verification and possible improvement. The present Report gives an abbreviated account of this analysis and presents numerical and graphical data sufficient to judge the reliability of Section 3.7.

Geology And Geological Structure Of The Alberta And Saskatchewan Plains, William E. Topley

Bachelors Theses and Reports, 1928 - 1970

Alberta, responsible for ninety per cent of Canada's output, had, by 1947 entered into her fifth year of production decline. Only ten per cent of Canada's oil requirements were secured from home fields. Ninety per cent had to be imported, mainly from the United States. How long could imports be maintained on present levels? During the year, the United States had started rationing; in one sector of its domain. Would this become general? If so, what was the answer for Canada?

An Investigation Of Soil-Cement For Use In A Parking Area, William Gus Koulas

Civil Engineering ETDs

The writer has confined his studies to the use of soil-cement for a parking area located at the State Fair Grounds in Albuquerque, New Mexico. This investigation was made with the expectation of using the existing soil with a minimum amount of cement as recommended for field use in the construction of soil-cement into a durable, serviceable and economical paved area.

Manganese Oxide Deposits Near Butte And Development Since 1942, Emmett M. Gilmore

Bachelors Theses and Reports, 1928 - 1970

The manganese minerals occur in the peripheral zone of the Butte district with quartz in veins, which at depth contain galena and sphalerite closely associated with silver-bearing minerals. The manganese oxides are all oxidation products formed by weathering of primary rhodochrosite or rhodonite.

Concentration Of Manganese Dioxide From Philipsburg, Montana, W. M. Mcauliffe

Bachelors Theses and Reports, 1928 - 1970

Imports of manganese ore probably supply a major proportion of the needs of the United States. Domestic production is reported to be higher than pre-war levels, but does not equal that of the peak production year of 1943. In 1946, the Anaconda Copper Mining Company ac­counted for 90 percent of the total shipments of mangan­ese nodules, and this company is the largest producer of domestic metallurgical ore in the United States.

A Mineral Dressing Study Of The U.S. Grant Ore, John Emmett Murphy

Bachelors Theses and Reports, 1928 - 1970

This investigation concerns the development of a satis­factory method or extracting or concentrating gold and silver from the ores of the U. S. Grant Mine. The choice between applying an extractive process and one by which the valuable mineral constituents are concentrated depends on more than one factor.

Karst Kamp Asbestos Deposits Gallatin County, Montana, Thomas L. Wilson

Bachelors Theses and Reports, 1928 - 1970

Karst Kamp, a southwestern Montana recreation re­sort, is 32 road miles south of Bozeman on the east bank of the Gallatin River in a narrow V-shaped valley flanked on the west by the rugged Madison mountain range and on the east by the equally rough Gallatin range. The asbestos deposit itself lies approximate­ly one-half mile northwest of the ranch on a heavily timbered "Al­pine-like" slope nearly 1200 feet above the floor of the valley.

Geology And Ore Deposits Of The Salt Chuck-Rush And Brown Mine Area Prince Of Wales Island, Alaska, Judson H. Whitman

Bachelors Theses and Reports, 1928 - 1970

The Salt Chuck, Rush and Brown, and adjacent mines and claims form an area of approximately 15 square miles near the head of Kasaan Bay about 10 miles northwest of the village of Kasaan on Prince of Wales Island in southeastern Alaska. It is an area of moderate relief in which the hills rise from the water’s edge to heights of some 500 feet. Most of the area is covered with dense vegetation and muskeg.

A Discussion Of The Geology And An Isopach Map Of The Pennsylvanian System In Wyoming And Adjacent Areas, B. R. Alto

Bachelors Theses and Reports, 1928 - 1970

Pennsylvanian strata in Wyoming and adjacent areas have been the subject of much work and discussion. Most of the work has been due to the economic importance of the system as an oil producer in this region. Oil production from strata of Pennsylvanian age is rather recent history; and therefore, much of the available information is local­ized and incomplete.

Sandstones Of The Lance And Fort Union Formations, Alan G. Conner

Bachelors Theses and Reports, 1928 - 1970

The Fort Union and Lance formations are widespread terrestrial sediments exposed in Montana, North Dakota, South Dakota, Wyoming, and Canada. Their stratigraphic position, especially that of the Lance, has long been in doubt, and has provoked much controversy among geologists.
