Studies In The Magnetic Rotation Of The Plane Of Polarized Light, Charles J. Glass

Bachelors’ Theses

As an introduction to the phenomenon of magnetic rotation it is well to offer a brief explanation of the phenomenon of optical activity. According to the ’’wave theory” of light the rays from any ordinary light vibrate in every conceivable plane. If 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 is found that the optical axes of the two prisms must be parallel to one another or the beam will not penetrate the second one.

A Study Of Gel Formation In Kerosene In Contact With Sodium, Jerome M. Weller

Bachelors’ Theses

The origin of the problem to be considered in this paper is traced to the observations of John R. Koob, Ph.D., Head of the Chemistry Department of Marquette University. It was his experience to note that the kerosene, in a bottle, containing cut sodium for the organic laboratory, had solidified to a gel, resembling Vaseline in appearance.

The Amount And Identification Of Amyl Alcohols In A Commercial Mixture Of Pentanols, M. Eugenia Eberhard

Bachelors’ Theses

Casing head gasoline obtained from natural gas yields five commercial products. One of these is a mixture of amyl alcohols. As treated by the Sharples Company, West Virginia, pentane is separated and treated with chlorine. Three chlorine derivatives are produced. These are treated with caustic soda and may f'orm eight possible amyl· aloohols~1 The products of the normal pentane, only, are the subject matter of this thesis.

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].

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

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 …

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 …

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 Official Methods Of Analysis For Determining The Availability Of Nitrogen In Fertilizers, Raymond A. Schmidt

Bachelors’ Theses

The Milwaukee Sewage Disposal Plant is unique in that it has successfully met the engineering and chemical problems encountered in putting the theories and ideas of the simple experimental station into operation on a large scale. Municipal sanitation was the aim of the plant. It has accomplished its purpose and has been operating several years with a high degree of efficiency and low per capita cost. The plant will be called upon to take care of the sanitary needs of Milwaukee for many years to come.

Torynobelodon Loomisi, Gen Et. Sp. Nov., Erwin H. Barbour

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

The group of proboscideans which we have called the shovel-tuskers or Amebelodonts, was announced in June, 1927,¹ following the discovery of Amebelodon fricki. In the field season of 1928, two additional species were found which are represented by mandibular tusks. One of these is a tip of a large and unique tusk, numbered 2-3-9-28, S. and L., the collectors being Bertrand Schultz and John LeMar, both of the class of 1931, the University of Nebraska. It was found within 200 to 300 yards of the spot on his farm where Mr. A. S. Keith, Freedom, Frontier County, Nebraska, found …

The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour

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

The ponderous mandible of the great shovel-tusked mastodon, Amebelodon fricki, was figured and described before it was practicable to remove the plaster cinches. In the meantime, this rare specimen has lain on its sand table awaiting the time when sections and casts could be made before mounting it permanently. A rare specimen, especially if heavy, unwieldy, and fragile, is rarely dismantled for study after it is mounted and installed in its case. A gelatine cast of the alveoli has been made, and through the assistance of Mr. Murray Jerome Roper, a cast of the left mandibular tusk has just been …
