The Sorption Of Fluoride Ion With Special Reference To Fluoride Removal From Potable Waters, Phillip W. West

Theses and Dissertations

The recent discovery that even very small concentrations of fluorides in drinking waters are sufficient to cause the serious dental dystrophy commonly known as mottled enamel, has around widespread interest and concern. Federal and State surveys have been conducted to determine the geographical distribution of the malady, and the fluoride contents of water supplies.

County dental surveys, conducted by the United States Public Health Department with the cooperation of local dentists, have located the regions throughout the country where mottled enamel is endemic and among these localities is an area in southeastern North Dakota and adjacent territory in South Dakota …

Problem-Solving In Arithmetic, Eva M. Acker

Bachelors’ Theses

For a century arithmetic has been a popular subject in the elementary schools, and has consumed more time than any other subject. The war had an effect in reducing this time on arithmetic, largely due to the war-time emphasis on health, food production, back-of-the-line morale, and kindred subjects. More recently, school activities and playground work have come in for a reasonable share of the school time. The Twenty-ninth Yearbook recognizes the child as the center of interest, and the final criterion of all values being the effect any technique of teaching or any content of instruction has on the child. …

Thomas William Robertson, The Mid-Victorian Dramatist, James A. Fitzpatrick

Bachelors’ Theses

It is the purpose of this thesis to determine the position of Thomas William Robertson in the dramatic history of the nineteenth century, and to discover what contributions, if any, he made to the drama of this period. In addition to making a careful analysis of Robertson's more important dramas, I have read all the outstanding dramatic histories of the middle of the last century and some of its popular dramatic works. In my investigation of this problem I have explained the dramatic conditions of the early and mid-nineteenth century, revealed the characteristic tendencies of its popular plays, set forth …

The Effect Of Fruit Acids On Aluminum, Glenore M. Dugan

Bachelors’ Theses

Aluminum has been used in cooking utensils for about thirty years and is still the favorite material employed. There is no disagreeable taste, odor or discoloration discernible from its use.

There have been many experiments to prove that aluminum does not depreciate the quality of the food cooked in it. It does, however, add itself to the acidic and basic foods cooked therein. The amount taken up by neutral foods is negligible.

For experimental purposes, fruit juices were chosen as the attacking substances and the strips of aluminum were of the quality used in ordinary cooking utensils, not cast aluminum.

A New Method For Determining The Rate Of Evaporation And The Relative Humidity, Willliam T. Shaw

Bachelors’ Theses

The presence of water vapor in the air is of the greatest importance to organic life. Animal and vegetable life is entirely dependent on water which very largely reaches the the earth through precipitation of water vapor held in the atmosphere. Not only does the water vapor in the air supply organic life with the life-giving fluid, but it also significantly modifies the climatic conditions of any region. Even in temperate climates such as in southern Australia, the air is often so dry that ordinary wooden furniture and articles of wood cannot be used because the air in this condition …

The Alkaloids, Felix F. Barre

Electronic Theses and Dissertations

This thesis, presented for the degree of Bachelor of Science, provides a systematic chemical study of the alkaloids, a class of complex nitrogenous plant substances possessing basic properties. Barre opens by defining the alkaloids and surveying the various systems used to classify them, whether by natural versus artificial origin, chemical nucleus (pyridine, quinoline, or isoquinoline), volatility, or botanical family of origin, and outlines their general physical and chemical properties, including solubility, optical activity, and characteristic reactions with precipitating and color-test reagents.

The thesis details standard laboratory methods for the extraction and separation of alkaloids from plant material, including a step-by-step …

The Conservation Of Nebraska's Water Resources, G. E. Condra

George E. Condra Publications

Oxygen is the first immediate necessity of life and water is second. Both directly and indirectly and more than soil, water is our most basic resource. It is the universal solvent and without it there would be no life, and, of course, no agriculture and industry.

The work also highlights public institutions, including the capitol building and the University …

The Cycloid, Some Related Curves And Their Derivation, Ann Downer

Bachelors’ Theses

In studying the history of the cycloid and the related curves, it is interesting to note that the earliest notations and explanations were given not by a mathematician but by an artist. The description and instrumental construction of the epicycloid curve was presented in about 1525 by Albrecht Durer (1471-1528) a celebrated sculptor and painter of Nurnberg in his book "Underweysund der Messung mit dem Zyrkenund Rychtsceyd." The original idea, however, goes as far back as the time of Hipparchus, an astronomer, who used it in his astronomical theory of epicycles. This curve was now neglected until G. Desargues and …
