Geology Of Smoke Hollow Area 8 Miles Southeast Of Deerlodge, Powell County, Montana, Floyd C. Bossard

Bachelors Theses and Reports, 1928 - 1970

This investigation was undertaken primarily as a problem in geologic mapping. The stratigraphy was studied as to the character, age, and sequence of the geologic formations that are exposed. The conclusions were based principally on the field relationships and lithology because no fossils were found.

Structure Of Southwestern Montana, Donald W. Levandowski

Bachelors Theses and Reports, 1928 - 1970

Intrusions of granitic rocks on a large scale are commonly found in the central part of folded mountain systems. Igneous rocks, intrusive and extrusive, are widespread in the mountains of southwestern Montana. An examination of the structural pattern of this area indicates that the fold trends form a radial pattern. How and why this pattern formed and its relation to the igneous activity in the area have not yet been discussed in the literature.

Basic Sills In Cottonwoood Creek Canyon, Jefferson County, Montana, Dale F. Kittel

Bachelors Theses and Reports, 1928 - 1970

A stratigraphic section of about 2600 feet of upper Beltian to lower Devonian formations exposed in Cottonwood Creek Canyon 11 miles east of Whitehall, Montana, contains about 20 igneous sills. These sills are from 5 to 20 feet thick, and grade from granogabbro to quartz basalt, except for one sill which is 165 feet thick, and is composed of granogabbro and red syenite. The whole sedimentary series is isoclinally folded, and the sills follow the bedding planes closely with localized crosscutting through the beds.

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.

A Test Of Richardson's Equation, Gerald J. Pyne

Bachelors’ Theses

Bachelors Theses and Reports, 1928 - 1970

The objective of this thesis is to determine the possibility of applying a different method to the re­covery of the copper dissolved in the Butte mine waters, and thereby precipitate a purer cement copper with greater efficiency and less iron consumption.

It's Time To Take Stock

United States Environmental Protection Agency: Publications

Likening colleges and universities to the automobile industry may seem far-fetched, but is it? Each is engaged in fashioning and selling necessary products- one trained men, the other mechanical equipment. Both entered the post-war years with production at low ebb; unable to satisfy pent-up customer demands. Time and high-speed assembly lines have bridged the gap of gas buggy shortage. The impact of selective buying by a discriminating public is now real cause for concern among some of the motor moguls. Rumor has had it that schools teaching wildlife management are overproducing. We decided to gather facts and opinions at the …

Public Health Reports, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Preliminary tests with DDT for the control of mosquitoes, forest insects, and agricultural pests demonstrated that it was toxic to a wide variety of animal life. Because there were indications that the new insecticide would be widely used, apprehension was expressed by some groups that its extensive or indiscriminate use would cause extensive harm to wildlife.

The desirability of carefully controlled use was early recognized by those in charge of extensive programs for the control of insects of public health importance. A joint statement of policy for the use of DDT issued early in 1945 (1) by the Army and …

Physical Properties Of The Ternary System: Ethylene Glycol - Disthylene Glycol - Water, Robert Marvin Tombaugh

Master's Theses or Doctor of Nursing Practice

Since approximately two-thirds (12) of the energy from the fuel in automobile engines is converted to unusable heat, it is necessary that a method of cooling the engines be provided. In most present-day engines of this type, an indirect method is utilized, namely, the transfer of heat to a liquid and thence from the liquid to the surrounding air by means of radiators Water is universally used for the coolant liquid because of its availability and high heat transfer properties. However, water has its limitations. A significant limitation of water as a coolant is its corrosive action causing rust clogging …

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 …

The Theory Of The Specific Heat Of A Face-Centered Cubic Lattice, Charles Robert Bonnell

Masters Theses

"It is generally accepted that a normal crystalline solid can be pictured at absolute zero as an assembly of atoms at rest arranged at periodic lattice points. Since at higher temperatures each molecule becomes a harmonic oscillator about its lattice point, it is necessary to know the distribution of normal modes of vibration in order to calculate the thermodynamic properties of the lattice...Many approaches have been made to get a simple solution of the problem, but either accuracy is sacrificed for simplicity, or the solutions demand a very considerable amount of labor. The classical theories failed to explain the change …

The Determination Of The Solubility Of Hafnium Oxide In Aqueous Solution By The Radioactive Tracer Technique, Hampden O. Banks

Masters Theses

"To date, there is no information in the open literature concerning the solubility of hafnium oxide in water other than the fact that it is very insoluble. This lack of experimental information is due, partly, to the fact that hafnium is a relatively new addition to the list of known elements"--Introduction, page 1.

An Ecological Study Of The Foraminifera Of Mason Inlet, North Carolina, Daniel N. Miller Jr.

Masters Theses

"Mason Inlet. North Carolina is a lagoonal marsh area with warm-temperate water, the salinity ranging from fresh to salt water. Nine collecting stations comprise an ecological gradient across the environment.

Forty-two species of foraminifera are recorded from the inlet, ranging in their affinities from brackish water to open-sea facies. Several extensions of range are recorded both northward and southward.

Substratum conditions apparently control the distribution of foraminifera within the inlet. Clean, fine sand provided the largest faunal populations. A depauperate assemblage was found in an inorganic, argillaceous substratum. The largest population of arenaceous forms was found at the channel through …

Geology Of The Crystal Mine, Hardin County, Illinois, John Amsden Emery

Masters Theses

"The study of the geology and mineralization of the Crystal Mine was undertaken at the suggestion of Mr. Dodson G. Gibson of the Crystal Fluorspar Company, who allowed access to the mine and its records for this purpose. The problem was to develop a system of prospecting the so-called bedded-replacement fluorspar deposits of Hardin County, Illinois. It is believed that an economically feasible method has been developed. This method involves not only the actual finding of fluorspar, but also serves as a guide in revealing structural trends suggestive of mineralization.

The fluorspar deposits of the Crystal Mine are representative of …

A Grazing Incidence Vacuum Grating Spectrograph For Far Ultra Violet Spectroscopy, Lawrey Huber Chapin

Masters Theses

"Spectroscopy, in the region of the far ultraviolet from 100 Angstroms to 1000 Angstroms, requires special equipment and techniques, inasmuch as these wavelengths are highly absorbed by air. Many gases have resonant frequencies corresponding to the wavelengths mentioned and hence absorption bands appear in the spectrograms obtained by using spectrographs for the visible region. One solution of the problem of obtaining data in this region is to construct a spectrograph from which all intervening gas molecules have been removed, thus eliminating the absorbing material. A vacuum of 10⁻⁴ mm. of mercury is necessary to reduce the absorption to a value …

The Reflection Coefficient At The Truncated Corner Of A Rectangular Wave Guide, John Raymond Barcroft

Masters Theses

"The term wave guide refers to a hollow conducting tube (usually of rectangular or circular cross section) filled with a dielectric (or vacuum) and used for the transmission of electromagnetic waves. We shall consider the guide to be bounded by a perfect conductor and to be filled with a lossless homogeneous isotropic dielectric (or vacuum). The electromagnetic wave in the guide must of course satisfy Maxwell's equation. It must also satisfy the boundary condition that there be no tangential component of electric field at the surface of the conductor. If the electromagnetic waves traveling along the guide meet a discontinuity …

Purification Department Of Zinc Leaching Division At Anaconda, Montana, J. L. Brown

Bachelors Theses and Reports, 1928 - 1970

The original smelter, known as the Upper Works smelter, was located on the north side of the Warm Springs Creek, just 2 miles east of the city of Anaconda and 26 miles from the city of Butte. By the year 1894 this smelter had a capacity of 500 tons of ore a day.

The Vanadium Plant Of The Anaconda Reduction Works, Tom Liss

Bachelors Theses and Reports, 1928 - 1970

No complete history of mining and smelting will ever be written that does not include a major discussion of the Butte district. The colorful tale of this area plays a major role in the interesting stories of mining. In the fields of mining methods, labor relations end financial manipulations, the Butte area has set a standard.

An Investigation Of The Radioactivity Of Oilwell Drilling Fluid, With Depth, Of Wells In The Berland Field Of Rooks County, Milford W. Johnston

Master's Theses or Doctor of Nursing Practice

In reviewing the foregoing literature and in consideration of the very important place of the state of Kansas in the nation's production of petroleum, it was thought that possibly a contribution might be made to the general subject of geophysical prospecting for oil by the adoption and execution of the problem proposed by the title of this thesis. Since a similar but more scattered study of this problem had been previously made by Lippert with the use of an electroscope, it was considered worth-while to repeat the electroscopic observations together with Geiger-Mueller Counter observations on a new series of wells …

A Study Of Aldehyde Derivatives Of Metallic Sulfamates, Edmond A. Morin

Master's Theses or Doctor of Nursing Practice

Sulfamic acid at one time had no particular value, and very little was known about the physical and chemical properties of this acid. At the present time , however, this acid is a commercial product of considerable importance and extensive investigation has been conducted to discover its many chemical properties. A very interesting group of compounds derived from sulfamates are the aldehyde addition products. The aldehyde derivatives of calcium sulfamate were studied and had a particular interest because of their greater stability, especially in the isolated, solid form. The aldehyde addition products of calcium studied included benzaldehyde, furfuraldehyde, for aldehyde, …
