The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

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 …

A Study Of The Basal Cherokee In The Rolla Area, Thomas Daniel Murphy

Masters Theses

"The occurrence of outliers of Pennsylvanian age, probably Cherokee, in and about Rolla has long been known. The Bureau of Geology and Mines and the Department of Geology of the School of Mines at Rolla have been greatly interested in the many stratigraphic problems presents. The writer has, therefore, undertaken field and laboratory studies of certain of these problems"--Introduction, page [1].

A Study Of Crime And Criminal Statistics Of Phelps County, State Of Missouri, For The Period 1899-1929, Walter Llyn Bradford

Masters Theses

"It is only within very recent years that the study of Human Society has been undertaken in a really scientific manner. It is true that the social problems have been studied and ideas suggested and discussed for their solution since the very beginning of social organization, for nowhere has there been found a state of society so perfect that all members are completely satisfied with their well-being under it...The study of crime is a part of the science of sociology and must be made according to the same methods as apply to all other kinds of social phenomena"--Introduction, page 1-3.

Elutriation Of Flotation Products, Guenther Walter Frotscher

Masters Theses

"Since the first application of the flotation process in ore dressing practice, engineers have been busy solving the most delicate relations of metal distribution in the minerals to be treated...The desire for more information was the reason for research concerning the mineral distribution in fine flotation material with particular attention to the development of a suitable laboratory method of hydraulic classification or, as it is especially called, elutriation"--Introduction, page 1-4.

Geological Report Of Summer Field Trip 1928, Clarence A. Corry, Marcus Mccanna

Bachelors Theses and Reports, 1928 - 1970

The object of this trip and report was to familiarize the students of the Montana State School of Mines with methods of taking and mapping surface and undergound geology. All surface geology was mapped by means of plane table and alidade, and undergound work by means of Brunton compass and taps.

The senior class of the Montana State School of MInes under the supervision of Dr. E.S. Perry performed the work, which covered an area in Madison County including South Boulder Creek, near Jefferson Island, the Silver Star Mining District, and the Alameda Mine, near Virginia City.

A Study Of The Electrical Resistance Of Glass As A Function Of The Temperature, William Alfred Yager

Honors Theses

This work was undertaken with the initial intention of determining the specific resistance of various kinds of glass as a function of the temperature. Various methods of measuring the resistance of glass were tried. In this experimental work, 60 cycle alternating current was used throughout while the conductivity unit shown in Plate 1 proved a very satisfactory and convenient arrangement for comparing the resistance of glass at various temperatures. Time did not permit the measurement of specific resistances as intended.

The Theory Of Limits, Molly E. Davis

Bachelors’ Theses

The theory of limits is among the most important theories in mathematics as mensuration of curves, and surfaces, the treatment of series and the foundation of calculus rest upon this theory.

The Sensitivity Of The Ortho-Tolidine Test For Free Chlorine In Milk Serum, Estelle Downer

Bachelors’ Theses

In the Journal of Industrial and Engineering Chemistry for November, 1913, J.W. Ellms and S.J. Hauser introduced the ortho-tolidine test for the detection of minute quantities of free chlorine in water. Antecedant to the experimentation of the above men with ortho-tolidine, the starch-iodide test ·was universally used for the· detection of free chlorine. In this test, the chlorine is calculated by liberating iodine from potassium iodide by the available chlorine, and the iodine being titrated with sodium thio sulfate. starch solution is used as the indicator. However, this particular method offers difficulties in the presence of minute quantities of chlorine …

The Devonian Of The Bear River Range, Utah, I. Lavell Cooley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The geological column in northern Utah has had very little detailed study. Those who have made reports on this section have done so only in a very general way, making no detailed sections of any part of the column, excepting that of the Cambrian made by Walcott.¹ Other work has been done by Mansfield² in southeastern Idaho and a general section of the Devonian made in Green Canyon, Bear River Range, Utah by Kindle.³

Due to the lack of any detailed work of this nature being done in the Bear River Range, suggested the matter of making …

Tree Planting In Nebraska

Conservation and Survey Division

Introduction. This bulletin is planned to further the planting of trees and ornamental shrubbery in Nebraska. It is the result of cooperation between State, Federal, and University departments, and many State organizations.

The tree-planting campaign of this year (1928) is to begin early in the season and culminate in the American Forest Week (last week in April). It is a State and National movement, a welfare project worthy of the support of every citizen. The cooperation of all Nebraskans is invited.

A Means Of Making A Segregate Preparatory To Chemical Analysis Of The Sulphide Minerals In A Low-Grade Dolomitic Ore-Pulp Containing Lead, Zinc, And Copper, Julius Bruce Clemmer

Masters Theses

"The object of this investigation was to find a means of obtaining from a low-grade dolomitic ore pulp a segregate of the sulphide minerals of lead, zinc, and copper preliminary to chemical analysis so that the chemist's error of 0.03 per cent would be divided by the ratio of the segregate to the entire pulp, and hence be reduced. Two methods of obtaining the segregate were investigated: (1) By float-and-sink tests, and (2) by selective dissolution of the dolomite, which is the main gangue constituent of the ore"--Object of Investigation, page 3.
