The Middle Ordovician Section In East Central Missouri, Morris James Ingerson, Josiah Bridge Jan 1922

The Middle Ordovician Section In East Central Missouri, Morris James Ingerson, Josiah Bridge

Masters Theses

"One of the most serious difficulties confronting anyone working on stratigraphic problems in the Ozark area is the lack of detailed faunal lists of the various formations. A great deal of general work has been done, but very few detailed faunal studies have ever been published, and correlation of the Missouri section with sections in adjoining states is often difficult.

In a recent paper, Dake has discussed the origin and correlation of the St. Peter sandstone. In this study he found considerable difficulty in correlating the various formations above the St. Peter, and at his suggestion, the present study was …

Glucose From Corn Cobs, Barney Nudelman Jan 1921

Glucose From Corn Cobs, Barney Nudelman

Masters Theses

"The efforts of American chemists in recent years have been devoted largely to the utilization of our waste products...Corn cobs offer a particularly inviting field for research along this line on account of the large supply of cobs available and the variety of substances obtainable from them. One of the leaders in this branch of investigation is Dr. F. B. LaForge of the Chemistry Division of the Bureau of Agriculture, who has contributed numerous papers on the subject. In one of these, in collaboration with C. S. Hudson, he describes, among other things, the preparation of glucose, but recognizes the …


Characteristics Of Bacillus Influenzae, Georgena Josephine Clarke Jan 1921

Characteristics Of Bacillus Influenzae, Georgena Josephine Clarke

Masters Theses

"This organism is classed under the type of haemoglobinophilic bacteria, due to the fact that its growth is restricted to a special medium containing haemoglibin [sic]. It is a very small bacillus which in the sputum tends to show itself in aggregations, especially centering about other organisms, M. tetragenus in particular"--page 3.

Classification Of Springs, Kirk Bryan Jan 1919

Classification Of Springs, Kirk Bryan

United States Geological Survey: Staff Publications

Among the common phenomena of nature, springs are notable because of their high usefulness. Since the earliest times the homes of men have clustered around them. In arid regions their number and size may limit the population. In many humid regions springs are so numerous and similar that distinctions between them are not recognized, yet they may be caused by so many principal and minor factors or by so many combinations of these factors as to make the origin of any one spring exceedingly complex or obscure. An interesting account of the many erroneous notions held by the ancients regarding …

A Theorem On Semi-Continuous Functions, Henry Blumberg Jan 1918

A Theorem On Semi-Continuous Functions, Henry Blumberg

Department of Mathematics: Faculty Publications

Recently G. C. Young and A. Denjoy have communicated theorems—those in Denjoy's memoir are of an especially comprehensive character—dealing, in particular, with point sets where the four derivatives of a given continuous function are identical. It is the purpose of this note to treat an analogous problem that arises when "derivative" is replaced by "saltus." However, instead of confining ourselves to "saltus," we prove a more general theorem that applies essentially to all semi-continuous functions. We preface the proof of this theorem with the following

The Cost Of Producing Electricity At The Hamilton, Missouri Light And Power Company, Bernerd William Adams Jan 1916

The Cost Of Producing Electricity At The Hamilton, Missouri Light And Power Company, Bernerd William Adams

Bachelors Theses

"For those seeking information on the cost of producing electricity in steam plants, an unlimited amount of data may be found in the technical journals and text books. This information, however, is obtained from a careful analysis of the daily and hourly records kept by the largest central stations, hence, production costs are available only where the yearly out-put is several million kilowatt-hours. the small isolated stations of from one hundred to two hundred kilowatt capacity have not as a rule, become progressive enough to keep a complete record of operating costs...The test hereinafter reported was conducted from August 3rd. …


Some Chemical Problems In Geology, Reginald Scott Dean Jan 1916

Some Chemical Problems In Geology, Reginald Scott Dean

Masters Theses

"This thesis is in the main a compilation of the views held at this institution in regard to the problems discussed as interpreted by the author. No claims for originality are made except in the manner of presentation as the material used has been obtained by conference and class room work with Professor V. H. Gottschalk and Professor G. H. Cox and also to some extent with H. A. Buehler, State Geologist. On the other hand the material is an expression of these ideas as assimilated by the author and hence may in certain cases differ radically from the views …

A Phenomenon Of The Kansan Drift In Nebraska, Erwin Hinckley Barbour Nov 1914

A Phenomenon Of The Kansan Drift In Nebraska, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

Among the minor phenomena of the glacial drift in Nebraska there is one which, though rarely observed by the public, is of interest and should be commended to the attention of naturalists. The reference here is to certain large, well-defined masses or blocks of such materials as sand, gravel, and coarse pebbles, which occur imbedded in the drift clays along with glacial bowlders, and which presumably have been similarly transported and deposited. These masses or blocks vary widely in color, texture, and kind. They also vary from the glacial matrix in which they are found and are the more striking …

Studies On The Relation Of The Nonavailable Water Of The Soil To The Hygroscopic Coefficient, F. J. Always

Nebraska Agricultural Experiment Station: Historical Research Bulletins

These experiments were carried out in connection with and subordinate to various soil investigations, the object being to determine the relation of the final water content of the soil to the hygroscopic coefficient and to determine to what extent the moisture was removed from the different portions of the subsoil not penetrated by plant roots.


The Measurement Of Mineral Electrode Potentials, John Charavelle Ingram Jan 1913

The Measurement Of Mineral Electrode Potentials, John Charavelle Ingram

Bachelors Theses

"The present investigation was undertaken with a view to consider the variables which tend to cause inaccuracy in the above mentioned measurements and as preliminary to a further study of the subject by the Missouri Bureau of Geology and Mines. The subject is one which, judging from the work of others and from my own experience, will require much more experimentation before results are obtained which are sufficiently reliable for the use of the economic geologist"--Introduction, page 3-4.


Cross-Bedding In The White River Formation Of Northwestern South Dakota, Dean E. Winchester Jan 1913

Cross-Bedding In The White River Formation Of Northwestern South Dakota, Dean E. Winchester

United States Geological Survey: Staff Publications

Rocks of White River (Oligocene) age have been known for many years to constitute numerous isolated buttes and mesas in the northwest corner of South Dakota, but no detailed study of their character and structural relations had been made until 1911, when, during an examination of the lignite area of that country, the writer had occasion to study the relation of the younger rocks to those containing lignite beds.

Todd, in 1895, recognized the White River formation in the Slim Buttes and called attention to the area in the following language:

3. Miocene beds, both White River and Loup Fork, …


Volhard's Volumetric Method For Manganese, John A. Murphy Jan 1913

Volhard's Volumetric Method For Manganese, John A. Murphy

Bachelors Theses

"The purpose of this article and the data contained is an attempt to show how the percentage of manganese varies with different mounts of zinc salt present. It was also intended to determine the ratio of manganese to oxygen and zinc in the brown percipitate sic obtained upon the titration of manganese sulphate against a permanganate solution in the presence of varying quantities of zinc, but through an oversight the data is insufficient for this purpose"--Introduction, page 2.


Checker Board Drainage Due To Eroded Dikes, Julian Adolph Hielscher Jan 1912

Checker Board Drainage Due To Eroded Dikes, Julian Adolph Hielscher

Bachelors Theses

"The conclusions here drawn are the results of observations made during the past ten summers spent in this region while camping, fishing, and hunting; at first, with the native game wardens and fire rangers; later on independently or in company with some of the many tourists who annually visit this delightful region. In this manner it has been possible to cross and re-cross this territory in almost every direction. The highways into this wilderness are the streams and lakes and the only method of travel is by canoe, though short excursions can be made over land by following the paths …
