A Study Of The Behavior Of Zirconium In Aqueous Solutions And The Separation Of Radioactive Zirconium By Electrodialysis, Charles William Brauer Jr.

Masters Theses

"Nuclear reactor installations designed for power production must of necessity operate at higher energy levels than their experimental precursors. As these facilities increase in number, better solutions must be found for both technical and economic problems.

The disposal of waste materials is of primary importance and will require greater effort if satisfactory disposal methods are to keep pace with the increase of waste materials, produced by the increasing number of new nuclear facilities. The radioactive materials present in this waste material may constitute a valuable by-product from these operations if suitable and economic recovery procedures are developed. If the development …

A Theoretical Study Of The Mechanism For The Haeffner Effect, David Charles Jacobs

Masters Theses

"In 1953, E. Haeffner reported that when he had passed a direct electric current through a length of capillary filled with liquid mercury, the lighter mercury isotopes were enriched at the positive terminal and the heavier mercury isotopes were enriched at the negative terminal. This phenomenon is referred to as the Haeffner Effect. Since Haeffner’s original experiment, other investigators have obtained similar results in other liquid metal systems.

When a direct electric current passes through a metallic conductor a free energy gradient is established. The direction of the negative free energy gradient is in the direction of the positive terminal. …

Introducing Aquatic Ecology To Ninth Graders, Inez P. Sutton

Masters Theses

Chapter I

Introduction

In discussing the basis for teaching high school biology, Van Deventer¹ states, "...the present typical course in high school biology serves adequately neither the terminal student nor the college entrance student." He holds that today's courses present watered-down versions of college courses to the student before the intelligence of the student has matured enough to grasp such subject matter. As a result there is very little carry-over value from such courses, and the students may even develop a dislike for biology. This study constitutes an effort to understand these problems and to devise ways of solving …

The First British Labor Government 1924, Donald Black

Masters Theses

Introduction

In 1924, the Labor Part, assumed control or Britain's political destinies for the first time. Although its tenure or office was brief, from February through October of that year, it marked an important milestone in the slow, unrelenting progress of democratic socialism in the British political spectrum after the conclusion of World War I. Not only did it reveal that Labor could assume its role as an effective opposition Party, but also that Labor had the capacity to govern in a difficult and perplexing era.

Investigation Of Vertical Internal Spillways, Paul R. Munger

Masters Theses

"This investigation resulted in the development of a means of predicting the discharge of water through an internal spillway type rockfill dam. From the data obtained during the various tests, equations were developed by which the coefficient of discharge for an internal spillway type rockfill dam can be determined when the core height, rock size and head causing flow are known. The equations give results with an error of less than 5%, which is adequate for engineering works"--Abstract, page 2.

Apparatus For Inductive-Electromagnetic Model Studies, Won Ho Kim

Masters Theses

"The object of this research is to design, construct and calibrate an apparatus suitable for electromagnetic model studies. A portion of the thesis is devoted to general review and theoretical consideration of electromagnetic prospecting.

Theoretical analysis of electromagnetic survey data by mathematical methods can only be carried out for simple idealized subsurface conditions. Because of the difficulties of theoretical solutions, in contrast to the simplicity of the conditions of similitude in electromagnetic exploration, a model experiment offers a very useful means of studying and comparing the response of naturally occuring conducting mineral bodies.

An apparatus suitable for inductive-electromagnetic model studies …

Deformations And Bending Moments For A Building Slab With A Central Opening, Wu Ping-Yung

Masters Theses

"The adaptability of the classical slope-deflection method analysis to the analysis of uniformly loaded building slab is the subject of this study. The paper demonstrates the use of slope-deflection in computing deflections and bending moments in uniformly loaded square building slabs both with and without central square openings. The results obtained are compared with results of other methods found by other investigators.

Numerous methods have been proposed for use in solving plate or slab problems. The exact solution in the form of a fourth order partial differential equation has proved to be of value in relatively few cases where boundary …
