Dissociation And Life Cycle Of Bacillus Subtilis, Herbert C. Batson

Electronic Theses and Dissertations

B. subtilis is one of the oldest known bacterial organisms, having been described by Ehrenberg as early as 1838. It was later more accurately described and placed in its present classification by Gohn in 1872. It has served as the basis of many investigations, and it is doubtful if any other aerobic sporeforming organism is now as well known as this.

Autobiography Of Proteins In Nutrients, Marguerite Jones

Electronic Theses and Dissertations

This thesis, submitted to Xavier University in 1933, surveys the chemical classification of proteins and their role in human nutrition, with the stated aim of preparing home economics students to understand protein's function in the diet. Jones organizes proteins into three major classes: simple proteins, including albumins, globulins, glutelins, protamins, and histones; conjugated proteins, including nucleo-proteins, glyco-proteins, phospho-proteins, and hemoglobins; and derived proteins, including albumoses, peptones, and peptids, describing the chemical composition, solubility properties, and sources of each.

The thesis then examines amino acids as the end products of protein digestion, identifying those essential for growth and maintenance, including tryptophane, …

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 …

Greenhouse Studies On The Relationship Of Age Of Wheat Plants To Infection By Puccinia Graminis Tritici, George W. Eade

Electronic Theses and Dissertations

The resistance of wheat to the stem-rust organism (Puccinia graminis tritei) has been under investigation for a number of years. Although rust resistance has been investigated from various angles, there still remains a question as to the nature of resistance, the time when resistance first appears in plants and whether or not it is of a stable character. Peltier found that environmental conditions could change the degree and type of stem rust infection on wheat plants; Miss Hart proved that stomatal behavior was very important in the rust resistance, and Harrington and Aamodt studied the inheritance of rust resistance and …

The Effect Of Ultra-Violet Light Upon The Growth Of Zea Maize., W. H. Clashman

Electronic Theses and Dissertations

Many experiments have been performed to determine the effect of ultra-violet light upon the growth of plants and animals. The conclusions reached by the experiments concerned are not constant in all cases. The more significant of these studies are here reviewed. Sheard and Johnson (17) state that the skin is the medium which separates the organism, whether it be plant or animal, from its environment. The skin is, therefore, the medium of reception of radiant energy and the seat of transformation or utilization of the incident energy. No changes of a physical or chemical character are produced in the cells, …

The Effect Of Ultra-Violet And Infra-Red Rays Upon The Fission Rate Within A Single Clone Of Paramecium Caudatum And The Heritability Of That Effect., L. Sebastian Rose

Electronic Theses and Dissertations

Light in its various phases exerts a marked influence on the functional as well as the physical structure of all living matter. The phenomena of light involves two theories: (1) the wave or electro-magnetic theory conceiving light as consisting of electric emanations or waves of various frequencies and intensities given off from many substances. (The principle source of light as thus conceived is the sun with its estimated temperature of 10,000 F.); (2) the quantum theory which conceives light as a factor involved in ionization in chemical reactions (negative electrons are ejected from a surface of metallic iron when a …

Truancy In The Public Schools : Its Cause And Cure., Kathleen Miller

Electronic Theses and Dissertations

In this age in which we live it is not hard to find a problem but it is often difficult to choose one. These problems have arisen as a result of the complex social and industrial institutions which have evolved as a result of human inventiveness and the competition among men to better our living conditions and increase our comforts. According to statistics compiled by the General Federation of Women's Clubs, the proportion of those who enjoy these modern conveniences is small when compared to those who have suffered as a result. The problem of this study is one which …

The Origin Of Adventitious Roots In Coleus, Ethel Belk

Electronic Theses and Dissertations

It has long been known that adventitious roots develop from shoots and that adventitious shoots develop from roots. This fact is an important one to the horticulturist in propagating plants by stem or, root cuttings. The point of origin of these structures has not been fully presented. There have been various assumptions mad e as to where and how the adventitious structures arise. To avoid confusion, it is best to indicate that adventitious structures are those which are added to the plant; they are not the normal structures of the plant but are superfluous. They are not, however, superfluous for …

Reversal Of Polarity In Some Woody Dicotyledonous Angiosperms, Ida J. Rude

Electronic Theses and Dissertations

There has for some time existed a theory regarding organized or possibly unorganized formative substances which flow in different directions in the plant tissue and give to the supposedly polarized meristematic tissues of the plant the power to develop to maintain roots from one given or predetermined extremity and shoots from the opposite extremity only. According to theory – in case of the reversal of the position of these ends in relation to moisture, a corresponding reversal in type of plant organ produced will not ensue and persist. The experiment under discussion in this paper was carried out in an …

Some Philosophical Implications Of Behaviorism., Harold Wayland Tribble

Electronic Theses and Dissertations

Psychology is the middle ground between philosophy and science. Philosophy deals with the interpretation of facts, with, a view to determining their ultimate cause. It is the search for knowledge of general principles--elements, powers, causes and laws--as explaining facts and existences. Science is systematized knowledge of facts, laws and proximate causes, gained and verified by exact observation. Science is the effort to show how laws operate, and how certain facts affect other facts. Philosophy seeks to show why laws operate as they do, and to discern what is the first fact. Science deals with the sequence of events and effects …

A Chemical And Morphological Study Of Grindelia Squarrosa (Pursh) Dunal, Marcus A. Chase

Electronic Theses and Dissertations

A species of Grindelia known as Gum, Rosin or Tar weed, is of common occurrence on dry banks and sandy soils in various parts of South Dakota. During day seasons it attains such a dense growth in closely cropped pastures that horses feeding in them have their heads and manes covered with a black tarry-like substance, and their fetlocks collects fairly large ball of this tarry mass. In dry years the development of the weed is so rapid that the grass in a closely cropped pasture may be nearly exterminated during a single season. A pasture may seem to be …

The Effect Of Endocrines Upon Animal Behavior., J. Hubert Geyer

Electronic Theses and Dissertations

It is not the primary purpose of this present work to treat the problem of the evolution of behavior, but rather to give an analysis of animal behavior as observed. These observations may appear as simple tests, but they make possible a new way to measure the capacity and determine the rate of learning by the animal mind. Progress in learning takes place through increased variety and precision of the movements brought about by stimulation and is very clearly observed in Amoeba, where we find the production of varied movements and the resolution of one physiological state into another. Thus …
