Iron And Cobalt Salts As Catalysts In The Oxidation Of Sodium Sulfite By Free Oxygen, Loren C. Bryner Jan 1930

Iron And Cobalt Salts As Catalysts In The Oxidation Of Sodium Sulfite By Free Oxygen, Loren C. Bryner

Theses and Dissertations

The present investigation was carried out to show the catalytic effect of some iron and cobalt salts on the oxidation of sodium sulfite solutions by free oxygen. The rate of reaction was determined by measuring the volume of water required to replace the absorbed oxygen. A photograph and diagrammatical arrangement of the apparatus is given, (Page 14). From the preliminary experiments it was found that the rate of oxidation of sodium sulfite solutions is dependent upon concentration, and speed of the shaker.

The Mandible Of Amebelodon Fricki, Erwin H. Barbour Dec 1929

The Mandible Of Amebelodon Fricki, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

The type specimen of the genus Amebelodon is installed in the Nebraska State Museum, the University of Nebraska, Lincoln. It consists of a mandible with tusks and teeth, all of which are dense and perfect, barring minor cracks and breaks. One toe bone and part of a rib found associated with this mandible may belong to this animal. It was discovered by Mr. A. S. Keith on his farm near Freedom, Frontier County, Nebraska; was secured for the palaeontological collections of Hon. Charles H. Morrill by Mr. Phillip Orr, April 4, 1927; was briefly described and figured in a Museum …


Faraday's Laws Of Electrolysis, M. Aquinas Dec 1929

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 …

Scholasticism An Intellectual Basis And Unifying Principle Of Modern Science, Alice V. Johnson Jul 1929

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

Electronic Theses and Dissertations

Amid the almost uninterrupted disintegration of systems during the last three centuries, the philosophy of St. Thomas has alone been able to stand the shock of criticism; it alone has proved sufficiently solid and comprehensive to serve as an intellectual basis and unifying principle for all the new facts and phenomena brought to light by modern science.


The Chromite Deposits Of Stillwater And Sweetgrass Counties, Montana, Uuno Sahinen Jun 1929

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 Jun 1929

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 …

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 Jun 1929

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 Jun 1929

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 …

Quadratic Equations, Floyd George Hydar Jun 1929

Quadratic Equations, Floyd George Hydar

Bachelors’ Theses

In algebra, an equality which exists only for particular values of certain letters representing the unknown quantities is called an equation. These particular values are called the roots of the equation, and the determination of these roots is known as the solution of the equation.


A Study Of The Oxidation Of D-Glucose With Air In A Saturated Solution Of Barium Hydroxide, Clyde Wilson Eddy May 1929

A Study Of The Oxidation Of D-Glucose With Air In A Saturated Solution Of Barium Hydroxide, Clyde Wilson Eddy

Open Access Master's Theses (through 2010)

The conversion of one aldose into another aldose and several ketoses slowly by weak alkalis at ordinary temperatures and quickly with much decomposition at elevated temperatures, was first observed by Lobry de Bruyn and later investigated by Nef and his students in an elaborate study on the action of strong alkalis alone and with oxidizing agents extending over a period of ten years. The results of these studies on oxidation were interpreted as depending on the presence of several intermediate enediols. The oxidation of sugars in approximately six normal alkali medium with air or oxidizing agents all give about the …

Periodic Functions, W. Kenneth Koehler May 1929

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.
