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.

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.

Electrometric Microdetermination Of Water In Tungsten And Molybdenum Metal Powders By The Karl Fischer Reagent, Helen C. Efinger

Bachelors’ Theses

The problem of the determination of the moisture content or metal powders has been suggested by the Fansteel Metallur­gical Corporation, where I was formerly employed, as one which might prove of interest to them. I have been particularly interested in a topic of this nature since my only laboratory experience has been in metallurgical chemistry.

In this work I intend to make a comparison and evaluation of various methods of determining the moisture content of tungsten and molybdenum powders in order to show which would be the most applicable. Most of the common methods for determining the amount of moisture …

An Investigation Of The Charge Acquired By A Metal Plate When Irradiated By X-Rays, Bernard Keith Betz

Bachelors’ Theses

The Photo-electric effect upon metals irradiated by X-rays can, under certain circumstances be completely concealed by some other phenomenon, unless certain precautions are made. It is the purpose of this paper to discuss the properties of this phenomenon.

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.

Solidified Alcohols, Mary Kay Enright

Bachelors’ Theses

The relatively new field of science, colloid chemistry, has risen to become an important addition to man's knowledge of the behavior of matter in the natural world and in the laboratory. Although it can no longer be viewed as a new science, it is still new enough to contain unexplored fields and to intrigue the investigator.

The study of gel formation has been received with interest by chemists of the nineteenth and twentieth centuries. This phenomenon of sudden gel formation instead of the expected crystalline precipitate while extracting with alcohol was encountered often in experimental work.

The inquisitive mind would …

The Renova "Syenite" Porphyry Madison County, Montana, James H. Clement

Bachelors Theses and Reports, 1928 - 1970

Unique feldspar porphyries, syenitic in appearance, and granitic in composition, form an unusually thick sill intrud­ing pre-Cambrian Belt graywacke about eight miles south of Whitehall in southwestern Montana. Commercial deposits of gold and silver ores occur nearby, and may possibly be genet­ically related to the porphyry, although direct association is not evident. The geologic age is believed to be late Cretaceous or early Tertiary, and the sill may be related to the Tobacco Root batholith.

An Electrochemical Determination Of The Free Energy Of Formation And Solubility Product Constant Of Silver And Mercury Sulfides, Earl Lloyd Gray

Theses and Dissertations

Because present data on free energy of formation and solubility product constants of the metal sulfides are both inconsistent and based on very old experimental data, a new study using modern techniques is amply justified. Because metal sulfide precipitates are often colloidal and becasue the solubility of these sulfides is so low, ordinary physical and analytical methods are not applicable to a direct determination fo the solubility product constant. Therefore, a more reliable thermodynamic approach was undertaken in this study. The standard free energy of formation of silver and mercury sulfide was determined from electromotive force measurements of suitable galvanic …

An Investigation Into The Precipitation Of Copper From Mine Water By Cupric Copper Reduction, And The Subsequent Precipitation Of Copper As Cuprous Chloride, Jack T. Gentry

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.

Geology Of The Southern Ladron Mountains, Socorro County, New Mexico, E.A. Noble

Earth and Planetary Sciences ETDs

The Ladron Mountains are in a fault-block range consisting in large part of Pre-Cambrian rocks. They are flanked on the west by Paleozoic sediments and elsewhere by Tertiary and Quaternary deposits. The Pre-Cambrian rocks of the southern Ladron Mountains consist of a thick sequence of quartzite and schist which has been granitized by a sub-adjacent intrusion to such a degree that only remnants of unaltered quartzite and schist remain, the remainder of the rocks being largely paragneiss and para-granite. The nature of the intrusion is not known, but it is suggested that it may have been at least partly formed …

An Experimental Investigation Of The Alac Processes For The Volumetric Determination Of Phosphates, Gilbert O. Isaacson

Bachelors’ Theses

At present, the best method for the quantitative determination of phosphates is the long gravimetric procedure known as the phospho-molybdate method. Theoretically, a volumetric method using alkalimetry and acidimetry techniques should be applicable. The work reported in the following pages represents an attempt to apply this theory, and thereby greatly facilitate quantitative analysis f or this class of compounds.

A Study Of The Retail And Wholesale Distribution Of Frozen Foods In Tennessee, John F. Boyd Iii

Masters Theses

[From the Introduction]

One of the most amazing stories to come from the foods business during the past decade is the growth of the frozen foods industry. Its rapid development, after having partially solved many perplexing problems of production and distribution, was somewhat accelerated by higher consumer incomes and wartime scarcities. Equally important is the fact that housewives have been relatively quick to adopt frozen foods. Therefore, today frozen foods are occupying an increasingly important position and the industry no longer considers itself as being in the "infant" stage of development.

Prime Ideals In Semigroups, Helen Bradley Grimble

Masters Theses

The concept of prime ideal, which arises in the theory of rings as a generalization of the concept of prime number in the ring of integers, plays a highly important role in that theory, as might be expected from the central position occupied by the primes in arithmetic. In the present paper, the concept is defined for ideals in semigroups, the simplest of the algebraic systems of single composition, and some analogies and differences between the ring and semigroup theories are brought out. We make only occasional references to ring theory, however; a reader acquainted with that theory will …

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 Index To The Literature On Digenetic Trematodes From Fishes, Richard William Bond

University of the Pacific Theses and Dissertations

The primary purpose of this compilation is to facilitate for pertinent literature in the searches involving digenetic trematodes from fines. The index may be used by the investigator to determine what, Af any, 14torature has appeared concerning the animal or group of animals with which he is working; and the literature is cross-indexed in such a way that it may be approached from the various angles commonly used in trematodes investigations. There are included, for example, an index to hosts, an index to larval stages of development and a partial geographic index to adult trematodes of fishes.

Some Physical And Chemical Properties Of Loess Deposits In The Lower Mississippi Valley., Ellis Louis Krinitzsky

LSU Historical Dissertations and Theses

This study presents a general picture of loess in the Lower Mississippi Valley. Loess is recognized as unstratified, calcareous, slightly plastic, porous loam with an average grain size distribution between 0.05 and 0.01mm. diameter. Materials meeting this definition but lacking in calcium carbonate are termed "leached loess" when in association with loess and "brown loam" when not in association with loess.

Loess has been found to occur chiefly as pseudo-anticlinal caps on hills. It is mapped as occurring within an area averaging 10 to 15 miles in width extending from southern Illinois southward along the eastern walls of the Lower …

The Theory Of The Specific Heat Of A Body Centered Cubic Lattice, Curtis Cleveland Webster

Masters Theses

"In normal crystalline solids the atoms are at rest in their lattice points at absolute zero of temperature. Increasing the temperature of the crystal increases the motion of the atoms about their lattice points. Approximately, each atom or ion may be treated as a harmonic oscillator. then from the equations of motion of the atoms, by the Born-von Karman theory of specific heats, the normal modes of vibration of the lattice can be expressed as the roots of a secular determinant. Application of this theory to determine the thermodynamic properties of crystals has resulted either in solutions that are inaccurate …

A Determination Of The Surface Tension Of Bismuth, Cadmium, Tin, And Lead, Edward Mckee Chandler

Masters Theses

"Various methods have been employed for the determination of surface tension including capillary rise, drop weight, maximum bubble pressure, sessile drops on flat surfaces, sessile bubbles formed underneath flat surfaces, and the shape of pendent drops. Each method is subject to characteristic advantages and disadvantages. Only two of these will be discussed. The method of maximum bubble pressure allows the formation of a fresh surface for every bubble but does not permit the study of a given sample over a period of time. The sessile drop in direct contrast, allows the observation of the same sample over any period of …
