The Production Of Oxalic, Citric, And Gluconic Acids From Plantation Molasses, John A. Ruth
The Production Of Oxalic, Citric, And Gluconic Acids From Plantation Molasses, John A. Ruth
University of the Pacific Theses and Dissertations
This research was undertaken for the purpose of developing a process for producing citric and gluconic acids from plantation molasses.
There is an evident need for such a process. At the present time, these acids are being produced by processes in which refined sugar is the principal raw material. If molasses could be used in place of refined sugar, the cost of raw materials would be reduced by approximately ninety percent. In addition, a waste product would be utilized.
The scope of this problem is very broad. Its solution will involve the solving of many problems of widely varying natures. …

The Geology And Mammalian Fauna Of The Pleistocene Of Nebraska Part I Outline Of Pleistocene Geology Of Nebraska Part Ii The Pleistocene Mammals Of Nebraska, A. L. Lugn, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
The object of the present paper is to provide a suitable brief statement of the present state of knowledge of the Pleistocene geology of Nebraska, for an adequate understanding of the Pleistocene Mammal list, by Mr. C. Bertrand Schultz, which forms Part II of this report. The "outline" is necessarily brief and does not contain many detailed sections, nor lengthy discussions of controversial points. It is lacking in adequate detailed descriptions of new formations and may not be entirely convincing to many readers. The only excuse which the writer can offer for the shortcomings of the following pages is the …

The Relation Of The Native Forest Cover To The Physical And Chemical Nature Of The Soils Of The Mammoth Cave National Park Area, Sheppard Walker
The Relation Of The Native Forest Cover To The Physical And Chemical Nature Of The Soils Of The Mammoth Cave National Park Area, Sheppard Walker
Masters Theses & Specialist Projects
This study was undertaken for the purpose of determining the relation existing between the native forest cover and the chemical and physical properties of the soils of the Mammoth Cave National Park area. The study was suggested by certain references in the literature to a correlation existing between forest cover and the geological, chemical and physical nature of soils of this area. The recent attempt at reforestation in the Mammoth Cave National Park area renders such a study timely, and it is believed that the results reported in this paper will materially aid the Mammoth Cave National Park Commission and …

Electronic Theses & Dissertations
The object of this thesis is to present a further generealization of Kronecker's symbol and apply it to cubic determinants.
Part I contains preliminary work on the Kronecker smbol as generliazed by Murnaghan, and applied to the plane determianntns. It includes only material that is necessary in the explanation of part II.
In part II we make a further generalization by defining a symbol composed of three rows of indices. The elementary properties of this symbol are given, the cubic determinant is define by means of the generalized symbol, and certain theorems on cubic determinants are demonstrated.
These theorems were …
The Action Of Tertiary Butyl Hypochlorite On Certain Nitrogen Compounds, Myrl Lichtenwalter
The Action Of Tertiary Butyl Hypochlorite On Certain Nitrogen Compounds, Myrl Lichtenwalter
Electronic Theses & Dissertations
In an earlier unpublished study, made in this laboratory, of the preparation and properties of positive halogen compounds, it was found that the replacement of hydrogen on an imide nitrogen in certain compounds sensitive to hydrolytic agents could be accomplished in tertiary butyl alcohol solution. It seemed likely that this reaction took place through the intermediate formation of tertiary butyl hypochlorite. Such mechanism has been proposed by Sandmeyer to account for the formation of chlorylimino ethyl carbonate by the action of chlorine on an alcoholic solution of potassium cyanide. The isolation of tertiary butyl hypochlorite by Chattaway and Brackenburg makes …

A Brief Study Of The Cherokee Formation Outcrop In Kansas, Roland G. Holmes
A Brief Study Of The Cherokee Formation Outcrop In Kansas, Roland G. Holmes
Electronic Theses & Dissertations
The Cherokee formation is one of the important rock formations of Kansas. There has been much work done upon the coal beds of this formation but so far as is shown by a search of the available literature, there has been no work carried on making a study of the rock beds of the formation by means of chemical analysis.
This paper is an endeavour to do three things: (1) to make a brief study of the rocks of the Cherokee formation at various horizons, (2) to attempt to show by chemical analysis the position of the land mass from …
Leaching Copper Minerals In The Butte District, Kenneth C. Bellows
Leaching Copper Minerals In The Butte District, Kenneth C. Bellows
Bachelors Theses and Reports, 1928 - 1970
The history of mining in Butte is woven about three of our principal metals. The gold placers first attracted the attention of miners in 1863, and reached their peak production in 1867. Silver was the second metal mined, and this operation required the erection of large mills with a consequent increase in mining activity that made the district a prominent producer. Although the presence of copper in the silver ore had been known, the credit for the first development of the copper veins is due Senator W. A. Clark. The original Colusa, Mining Chief, and Gambetta claims were developed to …
The Calcite Veins Of The Livingston Formation, John Moore Conrow
The Calcite Veins Of The Livingston Formation, John Moore Conrow
Bachelors Theses and Reports, 1928 - 1970
An interesting group of calcite veins occur near Livingston Montana in a zone about eight miles wide and forty miles long in the edge of the Plains region of Montana in front of the Main ranges. The zone extends from the Boulder River south of Big Timber, through Springdale and Hunters Hot Springs, to Potter's Basin just north of Wilsall in Park County. The group of veins is particularly interesting because they cut relatively flat lying strata, suggest a structural relationship to one another, and they are nearly pure calcite.
The present investigation was to determine the position of the …
A Microscopic Study Of Some Volcanic Rocks In The Vicinity Of Butte, Evan Gustafson
A Microscopic Study Of Some Volcanic Rocks In The Vicinity Of Butte, Evan Gustafson
Bachelors Theses and Reports, 1928 - 1970
The rhyolite rocks in the vicinity of Big Butte present a very interesting, though complicated study. It seems that no extensive or conclusive work has ever been done upon these extrusives.
I have found that the rhyolites present a very interesting problem, especially microscopically, and that no doubt an intensive study along these lines will solve the problems concerning age relations of different flows and origin of the magma that produced the material for emanations.
A Study Of Montana Bentonite, William P. Ryan
A Study Of Montana Bentonite, William P. Ryan
Bachelors Theses and Reports, 1928 - 1970
Research has been undertaken both under Government and private auspices in an endeavor to develop uses for bentonite. Perhaps, the work done to date has had only in consideration the possible industrial importance of bentonite. No simple, quick methods for the determination of the properties or qualities of any particular bentonite have been developed.
In an attempt to establish whether or not there is a means of making rapid simple determinations of the quality of Montana bentonitic clays, and in particular, with regard to the uses to which the clays may be suited. The problem also involves a study of …
Methods Of Obtaining Asymptotes, Paul Sweetland
Methods Of Obtaining Asymptotes, Paul Sweetland
Master's Theses or Doctor of Nursing Practice
The purpose of this thesis is to present in logical order the more important methods of obtaining asymptotes. In several cases where two or more different methods for obtaining the same type of asymptotes were found the simpler method is given first and then the more difficult method. Most of the simpler methods are based on Analytic Geometry, while the more difficult are based on the Calculus.
Effect Of Impurities Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solution, Robert Jess Smith
Effect Of Impurities Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solution, Robert Jess Smith
Bachelors Theses and Reports, 1928 - 1970
There are many elements which are detrimental to the current efficiency in the electrolysis of zinc sulphate solution. Fortunately the majority of these elements are easily removed in the purification process and cause no further trouble. The elements that are likely to cause trouble in ordinary plant operations are antimony, arsenic, cobalt, nickel, manganese and germanium. The following tests were made to determine the mutual effect on the current efficiency when several of the impurities were present in the electrolyte.
