Revision Of The Jefferson City Formation In The Rolla Quadrangle, James Shelley Cullison

Masters Theses

"The geology of the Rolla quadrangle was mapped by Lee in 1912. At that time all the dolomitic strata above the Roubidoux and beneath the Carboniferous formations in this area were placed in the Jefferson City. A more detailed study of the stratigraphy of the whole Ozark region by Ulrich has shown that some of the strata which had been included in the Jefferson City formation on lithologic grounds are not equivalent to the dolomites in the type section at Jefferson City, Missouri"--Introduction, page [1].

A Syllabus Of Line Geometry, Alice Willmarth

University of the Pacific Theses and Dissertations

In the study of advanced geometry, we shall deal with a certain important relation between pairs of figures in space, and also between their properties. There are two distinct parts to analytic geometry, the analytic work and the geometric interpretation. Two systems of geometry, depending upon different elements with the same number of coordinates, will have the same analytic expressions and will differ only in the interpretation of the analysis. In such a case it is often sufficient to know the meaning of the coordination and the interpretation of a few fundamental relations in each system in order to find …

Faraday's Laws Of Electrolysis, M. Aquinas

Bachelors’ Theses

Physics has no equal, perhaps, in bringing the student to an appreciation of the beauty, the order and the harmony or the universe, and thus drawing the heart and the mind to God whose unbounded powers executed the eternal and marvelous wonders that are all about us.

It is intensely fascinating to take peeps into the "laboratories of God" and wonder what will be the next secret that He will let man in on. It seems as the ages roll by He gradually allows us to share more and more in His secrets or nature; He appears to be slowly …

The Chromite Deposits Of Stillwater And Sweetgrass Counties, Montana, Uuno Sahinen

Bachelors Theses and Reports, 1928 - 1970

In writing this report, two objects were kept in mind, (1) to explain, if possible, the origin of the chromite deposits found in Sweetgrass and Stillwater Counties, and (2) to bring up to date all information on these deposits which had thus far been available.

The work done consisted of study of the rocks and ores of the area under the microscope, both as thin sections and as polished sections, practically all of which was done at the Montana State School of Mines, during the school year of 1928 - 1929.

The rock specimens and much information as to their …

The Cycloid, Some Related Curves And Their Derivation, Ann Downer

Bachelors’ Theses

In studying the history of the cycloid and the related curves, it is interesting to note that the earliest notations and explanations were given not by a mathematician but by an artist. The description and instrumental construction of the epicycloid curve was presented in about 1525 by Albrecht Durer (1471-1528) a celebrated sculptor and painter of Nurnberg in his book "Underweysund der Messung mit dem Zyrkenund Rychtsceyd." The original idea, however, goes as far back as the time of Hipparchus, an astronomer, who used it in his astronomical theory of epicycles. This curve was now neglected until G. Desargues and …

The Study Of The Curves Of The Equations Having The Type Form X^N + Y^N = A^N, Lena S. Reif

Bachelors’ Theses

The object of this thesis is to determine the general properties of the family of curves, x^n + y^n = a^n from some of the specific curves in that family. The first curve to be considered is the one in which a = 4 and n =1. x+y = 4

Studies In The Magnetic Rotation Of The Plane Of Polarized Light, Richard J. Stollenwerk, Clifford R. Haymaker

Bachelors’ Theses

Before entering upon a discussion of the historical development of the subject of magnetic rotation, it may be well to explain briefly the nature of the phenomenon under investigation. According to the wave theory of light, the rays from any ordinary light source vibrate in every conceivable plane. If now the light is reflected from a glass surface or passed through a Nicol prism, it undergoes a change. If an attempt is made to pass the beam through a second Nicol prism, it is found that the optical axes of the two prisms must be parallel to one another or …

The Constant Of Torsion Of A Given Wire, Ella M. Blunk

Bachelors’ Theses

"Using a given wire, the value of n determined dynamically is generally somewhat larger than the value determined by statical method. This is due partly to the fact that a wire, under the action of a torque, does not at once acquire its final twist. The twist increases under the application of a constant torque; and therefore, during a brief application of the torque (for example, during an oscillation of heavy body attached to the wire) the torque per unit twist has larger value than when the torque is applied for a long time. " Edwin Edser

The purpose of …

Periodic Functions, W. Kenneth Koehler

Bachelors’ Theses

The first known publications on the periodic functions were those of Fantet de Lagnv, a French mathematician born at Lyons in the year 1660. Although previous to this, mathematicians, notably Galilio in his analysis of the cycloid, had studied functions and curves whose properties necessarily involved periodic functions, no specific mention of this property was made.

Elutriation Of Flotation Products, Guenther Walter Frotscher

Masters Theses

"Since the first application of the flotation process in ore dressing practice, engineers have been busy solving the most delicate relations of metal distribution in the minerals to be treated...The desire for more information was the reason for research concerning the mineral distribution in fine flotation material with particular attention to the development of a suitable laboratory method of hydraulic classification or, as it is especially called, elutriation"--Introduction, page 1-4.

A Study Of Ball Mills, Robert Lee Kidd

Masters Theses

"The study of the ball mill is very complicated, due to the varying conditions existing in the mill. Some of these conditions are: Size of grinding media, size of feed, moisture content, and speed with its effect on the paths of the grinding media. A brief history of fine grinding will first be outlines, after which some of the theories of ball milling will be stated. Then the paths of the grinding media will be given some attention, and a new point of view about the trajectory will be brought out"--Introduction, page 2.

Reaction Of Metallic Iron And Copper Sulphate In The Flotation Of Sphalerite, Charles Wilson Ambler

Masters Theses

"Copper sulphate is a common flotation reagent for blende ores. Metallic iron is also present in the mill circuit and a reaction between the iron and the salt would be in accord with well known chemistry. The abundance of metallic iron in a flotation feed may be noted by the examination of any feed. It originates, first of all, in the mine, then the coarse crushing machines contribute their share, and finally the fine grinding medium is a large contributor. If the grinding is with cast iron balls in amount of metallics is greater than when steel is used. In …

A Study Of The Basal Cherokee In The Rolla Area, Thomas Daniel Murphy

Anhydrous Alcohol And The Vapor Phase Method Of Preparing It, Cleetis Brown

University of the Pacific Theses and Dissertations

Since the almost universal laboratory method of preparing absolute alcohol requires considerable time and trouble, gives a low yield of alcohol and leaves a distilling flask badly clogged with hydrated lime, Professor S.S, Kistler and I undertook the following research in the hope that we might devise a new method that would be both rapid and easy to perform.

Upon reviewing the possibilities, it seemed evident that any method to be rapid would have to involve drying In the vapor phase. Diffusion in a liquid being so slow that when a drying agent is placed in the liquid phase an …

Scholasticism An Intellectual Basis And Unifying Principle Of Modern Science, Alice Veronica Johnson

Electronic Theses and Dissertations

This thesis, completed at Xavier University of Louisiana in 1929, argues that Scholastic philosophy, and the thought of St. Thomas Aquinas in particular, supplies an intellectual foundation that unifies the findings of modern science. Johnson takes up the common charge that Scholasticism is a barrier to scientific progress. She contends instead that it is the one philosophy able to answer the ultimate questions of “whence” and “how” that science cannot address on its own.

Johnson tests this claim against several fields in turn: astronomy, geology, physics, chemistry, and psychology. In astronomy, she reviews competing theories of the origin of the …

A Study Of Crime And Criminal Statistics Of Phelps County, State Of Missouri, For The Period 1899-1929, Walter Llyn Bradford

Masters Theses

"It is only within very recent years that the study of Human Society has been undertaken in a really scientific manner. It is true that the social problems have been studied and ideas suggested and discussed for their solution since the very beginning of social organization, for nowhere has there been found a state of society so perfect that all members are completely satisfied with their well-being under it...The study of crime is a part of the science of sociology and must be made according to the same methods as apply to all other kinds of social phenomena"--Introduction, page 1-3.

Theories Of Color And Color Vision, M. Regina Wallesch

Bachelors’ Theses

Theories of color have occupied the human mind since an early date even to the present. According to Professor Frank Allen there are from sixty to seventy different theories. Plato considered color to be due to flame-like particles projected from the pores of matter into the eye. Aristotle thought colors arose from various combinations of white and black.

Geological Report Of Summer Field Trip 1928, Clarence A. Corry, Marcus Mccanna

Bachelors Theses and Reports, 1928 - 1970

The object of this trip and report was to familiarize the students of the Montana State School of Mines with methods of taking and mapping surface and undergound geology. All surface geology was mapped by means of plane table and alidade, and undergound work by means of Brunton compass and taps.

The Sensitivity Of The Ortho-Tolidine Test For Free Chlorine In Milk Serum, Estelle Downer

Bachelors’ Theses

In the Journal of Industrial and Engineering Chemistry for November, 1913, J.W. Ellms and S.J. Hauser introduced the ortho-tolidine test for the detection of minute quantities of free chlorine in water. Antecedant to the experimentation of the above men with ortho-tolidine, the starch-iodide test ·was universally used for the· detection of free chlorine. In this test, the chlorine is calculated by liberating iodine from potassium iodide by the available chlorine, and the iodine being titrated with sodium thio sulfate. starch solution is used as the indicator. However, this particular method offers difficulties in the presence of minute quantities of chlorine …

A Study Of The Electric Current Rectifying Properties Of Metallic Salts In Contact With Metals, Simon Sander Share

Bachelors’ Theses

The property of offering greater electrical resistance to a current when flowing in one direction than when flowing in the opposite direction possessed by some metallic salts in contact under pressure with certain metals is of interest both from a purely scientific viewpoint and from a commercial viewpoint. The phenomenon is of interest to the scientist because it has not yet been properly explained and because a suitable explanation might lead to a better understanding of what actually occurs at the contact surfaces of a metal and a salt and also of the condition of metallic surfaces. The property has …

Graphical Calculation And Computation, Alice Hudson Vallier

Bachelors’ Theses

The word ’’graph” has lately become a part of the active vocabulary of the ordinarily educated person of today. We may say lately because even fifty years ago the use of the graph to represent data was limited to the knowledge of a few theorizing mathematicians and the miscellaneous disorganized usage of some practical mechanics, engineers, business men and statisticians. The situation is not that fifty years ago the rudiments of graphing were not identical with the bases of graphing data today, at least by such simple methods as are commonly employed in periodicals and newspapers for the enlightenment of …

A Study Of The Temperature Behavior Of Various Liquids When Subjected To Pressures Ranging Between One And One Hundred Pounds Absolute, Jerome John Van De Kamp

Bachelors’ Theses

This thesis is submitted as a partial requirement for the degree of bachelor of science. The problem is one which dates back as far as the science which claims its authorship. It is a problem of which very little is known and one is justified in calling this old problem a youthful one, youthful, of course, in the sense that it is immature and as yet undeveloped. The problem by the very fact that it is in its infancy makes it one of Infinite length. It is a problem which has no greater practical application. Its ultimate value extends into …
