Studies Of Surface Films Formed By Adsorption Of Polar Organic Molecules On Activated Metal Surfaces, Roy Leo Bennett

Doctoral Dissertations

The investigation of adsorption has been a valuable aid in under­ standing the properties of metal surfaces. The surface of a metal differs from the interior of the material due to unsatisfied valence forces which impart an affinity for adsorbed materials. This high sur­face energy is illustrated by the fact that when two clean metal sur­faces are placed in contact, that is, when there is no intervening adsorbed film, cold welding results. The resulting bond is equivalent to the bonding in the rest of the metal. This has been demonstrated by Bowden and Young,l who showed that mere contact of …

Role Playing As A Means Of Selecting Administrators, Charles Warren Hartsell

Doctoral Dissertations

Introduction: In view of the constant search for competent administrators on all levels of school administration, there is a need for defining the personal and operational characteristics which will indicate to an employer how a person will react in a given set of circumstances, particularly those which are related to the specific position involved. For example, how would a principal go about dealing with a parent whose child has been suspended from school for disciplinary reasons? How can we know, beforehand, whether an individual will be a good or a poor administrator? Industry has developed time and motion studies for …

Groups And Algebraicity In Complete Rank Rings, Robert James Smith

Doctoral Dissertations

Introduction: It is well known that many of the results in classical linear algebra have an unequivocal extension to the more general situation when the scalars are drawn from an arbitrary division ring K. There are, however, three distinct theories of determinants for matrices over a division ring. One of these, originated by Study, "apples only to very particular non-communicative fields and to matrices of special type" (Dieudonne) and will not concern us here. The remaining two, one due to Ore and the other due to Dieudonne, reflect together, if not separately, the basic properties of the classical determinant. The …

The Role Of Learning In Olfactory Sensitivity, Monroe P. Friedman

Doctoral Dissertations

INTRODUCTION: In recent years the psychological literature has reflected an increasing interest in the role of learning in perception. On the theoretical level, this interest is expressed principally by the considerable attention given to two current attempts to account for perceptual learning (Gibson & Gibson, 1955a: Postman, 1955). On the empirical level, the problems of industry and the military have generated a multitude of investigations in this area. These problems range in diversity from the training of military personnel in the identification of aircraft to the training of tasters in the food industry.

The remainder of this chapter will be …

An In Situ Method For Alteration Of Catalytic Activity By Generation Of A Reactant On The Surface Of The Catalyst, Clyde Dunn Alley

Doctoral Dissertations

In many researches dealing with catalysis there are properties of the catalyst that are attributed to the effect of hydrogen on the surface of the catalyst. The interpretations of the effect of hydrogen on the catalyst surface range from statements which indicate that surface hydrogen is necessary for the reactions to proceed to statements that surface hydrogen is a poison on the reaction. A clearly interpreted picture of the role of hydrogen at the present time is not available.

Rural Community Development: A Study Of The Relevant Sociological Theories, Ramaswamy Dwarakinath

Masters Theses

On account of this incomplete grasp of the concept in different regions and at different levels, and also on account of the lack of its systematic treatment in the theoretical spheres, there is an ever-growing need for examining the contemporary thought and experience and for gaining an integrated understanding of the subject, from time to time.

The focus of the present study is on one aspect of this situation, namely, the apparent paucity of a foundation of sociological theory to the concept of community development. The purpose of this thesis may therefore be stated as "the study of the theoretical …
