Pyrochemical Changes In Missouri Halloysite, Frank Joseph Zvanut

Doctoral Dissertations

"For centuries it has been known that the application of heat to a clay or a clay body produces changes that make it an entirely different substance from the original raw clay. Ever since the earliest civilizations produced crude building brick by baking formed clay bodies in the sun's rays, mankind has been speculating on the nature of the changes that convert soft, friable, plastic clays into hard, strong, non-plastic, rock-like masses. It has been only within the last two decades, however, that progress has been made in the solution of problems dealing with the resultant products in fired clay …

The Preparation And Properties Of Diphenylthiocarbazone, Floyd C. Mcintire

Theses and Dissertations

At present the chemical literature offers no method for the preparation of diphenylthiocarbazone, or dithizone, sufficiently detailed to guide the average laboratory technician in an economical and successful preparation of this compound. The high price of dithizone and the limited number of dispensers of it emphasize the need of such a method. The original research reported in this thesis was done primarily in an attempt to formulate a satisfactory detailed method for the preparation of dithizone. The suggestions of Emil Fischer were followed and an attampt was made to improve his outline and to note the possible errors so that …

Wood Occurring In The Ginkgo And Associated Petrified Forest (No. 1-The Gingko), George F. Beck

All Faculty Scholarship for the College of the Sciences

The most interesting single fossil tree, but at the same time the most difficult to determine in the Ginkgo Petrified Forest (Washington), is the tree after which this unusual petrified forest takes its name. The ginkgo is not only the world's oldest and most remarkable living tree, but it has long been regarded as holding the most striking fossil record of any living thing, plant or animal.

Grinding Thin Sections For Determining Petrified Woods, George F. Beck

All Faculty Scholarship for the College of the Sciences

The collector and student of petrified woods cannot long be satisfied to merely place these colorful and interesting specimens in the cabinet with the mere label, "petrified wood." Frequently determining the types of wood which once thrived in a given area is of importance to give a clue to climatic conditions of past geological ages. The collector should at least be qualified to recognize the more common woods and distinguish one family of trees from another.

The Value Of High School Physics To The College Student, Emery White

Masters Theses & Specialist Projects

Secondary school science consists of biology, chemistry, physics, or a combination course known as general science. General science deals only with the practical side of the laws of physics. It fails to go into detail and very often omits the law entirely. Physics in high school requires a special room in the building which is not easily adapted to other use. A large amount of expensive equipment is need to teach it efficiently. Can all of this expense be justified? Is the student who ends his school career with high school graduation sent out into life with a large amount …

A Pleistocene Lake In The White River Valley, Paul Macclintock, Erwin Hinckley Barbour, C. B. Schultz, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

DURING the course of a field conference on the Pleistocene geology of western Nebraska, carved sediments were found in the headwater drainage of White River near Crawford, Nebraska. A reconnaissance of White River Valley revealed them to be present also in the mid-course, near Interior, South Dakota, and at the mouth, near Chamberlain, South Dakota, where the White River joins the Missouri (Fig. 1). These isolated occurrences of varves, over a distance of 240 miles, are so similar that a correlation seemed possible. Furthermore, since the varves occur within the area where Yuma artifacts are found, it was thought that …

A Study And Application Of The Process Of Supergene Enrichment Of Silver Ores., Arthur C. Verling

Bachelors Theses and Reports, 1928 - 1970

In many deposits of silver ores the grade of the ore de­creases considerably a few hundred feet below the surface. It is believed that in many cases the better ores owe their richness in part to the process of sulphide enrichment. It is recognized, however, that many rich silver ores are hypogene deposits that have been affected very little, if any, by processes of enrichment.

Chemical Analyses Of Some Oil-Well Waters Of Russell, Ellis And Trego Counties, H. Everett Runyon

Master's Theses or Doctor of Nursing Practice

Considerable work dealing with analysis of oil-well waters of other areas has been published, but to the knowledge of the author, none has been published dealing specifically with the waters of this area. While the waters dealt with in this paper are not far different from the waters of the Midcontinent area as a whole, there are certain differences which are noticeable. For instance strontium is found in the top waters of the Eldorado, Kansas field. None has been found in this area. The sulphate content of the top water here is very high. Both apparently cause trouble at times. …

A Study Of The Effect Of Oxygen On The Rate Of Dissolution Of Gold In Cyanide Solutions., John A. Cook

Bachelors Theses and Reports, 1928 - 1970

The accepted chemical reactions in the dissolution of gold by cyanide solutions require the presence of gold, cyanide, water, and oxygen. The importance of dissolved oxygen in cyanide solutions as a factor is recognized by those familiar with cyanidation. Manufacturers of cyanidation equipment realize the necessity of oxygen, as shown by the appliances they have developed which are attached to the agitators in order to saturate the cyanide solutions with air.

The Control Of The Grain Size Of Zinc, Oswald J. Wick

Bachelors Theses and Reports, 1928 - 1970

The use of zinc as a structural metal has been militated against by two of its properties, namely, its low tensile strength and its susceptibility to grain growth. The importance of these factors can be appreciated when it is realized that the tensile strength of coarsely crystalline cast zinc is 4,000 pounds per square inch, while finely crystalline cast zinc has a tensile strength of 12,000 pounds per square inch.

Contact Metamorphism In The Highlands, Frank Trask Jr.

Bachelors Theses and Reports, 1928 - 1970

On the southern margin of the Boulder Batholith, about twenty miles south of Butte in the Highland Mountains, there are many miles of contact between the igneous and sedi­mentary rocks. As two kinds of igneous rocks and many diff­erent kinds of sedimentary rock are present, it is an excell­ent place for the study of contact metamorphism.

A Comparison Of Ths Digestive Powers Of Trypsin And Papain On Casein And The Effect Of Certain Mild Antiseptics On These Powers, Joseph E. Steker

Bachelors’ Theses

The purpose of this thesis is to study the effect of certain mild antiseptics, such as Benzoic acid, Boric acid, salicylic acid, Phenol, Cresol, Thymol, on the digestive action of the enzymes Trypsin and Caroid (papain). A thorough perusal of the literature reveals only a small amount of data dealing with the influence of common antiseptics on enzyme action. Because of the important uses of enzymes in industry and the need of antiseptics for protective action, this problem is of great importance. The author wishes to acknowledge the kind cooperation of Dr. John R. Koch, Head of the Department of …

A Study Of The Decomposition Potentials Of A Commercial Gluconic Acid Bath, Roman L. Pozorski

Bachelors’ Theses

The study of electrochemistry is not only fascinating and worthwhile, but essential to the student of chemistry in the understanding of many theories and chemical phenomena. Though electrochemistry is still in its infancy, numerous substances are prepared electrolytically in industry. It is reported that about 15% of all the chemical goods manufactured are prepared by electrochemical industries. Of the various types of studies, in electrochemistry, the one which appears to be most appealing is the analysis of chemical reaction sin which electrochemical methods are used. The determination of decomposition potentials is one of these methods. A knowledge of decomposition values …
