The Effect Of Ultra-Violet Light Upon The Growth Of Zea Maize., W. H. Clashman Jan 1930

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, …


Scholasticism An Intellectual Basis And Unifying Principle Of Modern Science, Alice V. Johnson Jul 1929

Scholasticism An Intellectual Basis And Unifying Principle Of Modern Science, Alice V. Johnson

Electronic Theses and Dissertations

Amid the almost uninterrupted disintegration of systems during the last three centuries, the philosophy of St. Thomas has alone been able to stand the shock of criticism; it alone has proved sufficiently solid and comprehensive to serve as an intellectual basis and unifying principle for all the new facts and phenomena brought to light by modern science.


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 Jan 1929

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 Jan 1929

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 Jan 1928

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 Jan 1928

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 Jan 1927

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 Jan 1925

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 Jan 1924

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 …


The General Cytology Of The Aecium Of Dicaeoma Distichlidis, Lynn D. Hutton Jan 1923

The General Cytology Of The Aecium Of Dicaeoma Distichlidis, Lynn D. Hutton

Electronic Theses and Dissertations

In the summer of 1921, Professor E.J. Petry noted an unusually severe uredinial infection on a small patch of Spartina cynosuroides (L) Roth, along the Chicage and northwestern right-of-way near Brookings, South Dakota. Along with this occurred an aecidial infection on Steironema ciliatum (L) Raf. Since the Steironema was small and mingled with the Spartina in places, a connection between the telial stage of the latter with the aecidial attack was trongly suspected. The infection occurred only on the lower leaves of the Steironema and this heightened the probabili8ty of infection from the teliospore sporadia of the Spartina which lay …


The Effect Of Condensed, Dry, And Fresh Milk In The Diet Of Albino Rats., John T. Walsh May 1922

The Effect Of Condensed, Dry, And Fresh Milk In The Diet Of Albino Rats., John T. Walsh

Electronic Theses and Dissertations

Although much work has been done in determining the nutritional values of different milks, all of it has been carried on at different times by various men, and there is no published data demonstrating the relative values derived from experiments which were carried on simultaneously and in which all subjects were under the same conditions. It is well known that rats show the effect of conditions to which they are subjected very easily and respond to them in the same manner in which man does. They are therefore a fit subject for nutritional experimentation. The Albino rat lives three years …


Concerning The Degree Of Self Fertilization In Corn (Zea Mays Indentata) That Is Obtained Under Normal Field Conditions, George Janssen Jan 1922

Concerning The Degree Of Self Fertilization In Corn (Zea Mays Indentata) That Is Obtained Under Normal Field Conditions, George Janssen

Electronic Theses and Dissertations

"Like begets like”. This well-known phrase which aroused so much comment among students in genetics and animal breeding has almost unconsciously become an adage to a part of their philosophy. Whatever truth or lack of it is associated with these words we admire the keenness of observation of him who wrote them. However significant the words "like begets like" could it be strictly adhered to our problem in breeding a cross-fertilized population would be greatly lessened. Much has been done in plant and animal breeding and the methods employed in accomplishing the greater part is without written history. Here and …


Nitrogenous Constituents Of Condensed Milk, With Special Reference To Total Non-Protein Nitrogen, Urea Nitrogen And Uric Acid., Bess Burton Mathis Jun 1920

Nitrogenous Constituents Of Condensed Milk, With Special Reference To Total Non-Protein Nitrogen, Urea Nitrogen And Uric Acid., Bess Burton Mathis

Electronic Theses and Dissertations

The most important non-protein nitrogenous constituents of milk are urea, creatinine, creatine, and uric acid. Urea is the diamide of carbonic acid and is the chief end-product, so far as nitrogen is concerned, of the physiological metabolism of the proteins of the foods and tissues. It has long been considered a matter of greatest importance to ascertain in what organ or tissues urea is formed. Investigations have gone so far as to demonstrate that it arises in part, at least, in the liver – that the liver cells are able to convert ammonium carbonate into urea which is then given …


Some Phases Of The Rural Sociological Situation., Jonas William Boyer 1890-1947 May 1915

Some Phases Of The Rural Sociological Situation., Jonas William Boyer 1890-1947

Electronic Theses and Dissertations

This treatise is not intended to cover the whole field of Rural Sociology. It deals briefly with the more important phases of the subject. Perchance many important problems have been omitted which the reader will call to mind. This will go to show that the reader is thinking about the subject, and will be led to consider further the welfare of the rural population. The Science of Rural Sociology is rather new in consideration, but the oldest of all sciences in practice. The original inhabitants of this world were ruralists, and necessarily social conditions sprang up with them which needed …


The School Garden From An Educational View Point., Emilie Yunker May 1911

The School Garden From An Educational View Point., Emilie Yunker

Electronic Theses and Dissertations

"School gardens are not intended to create gardeners or farmers but to afford the growing boy or girl an opportunity for many aided developments." In the school garden the children are taught by one who can inspire them with a love not only for plants, but for everything else that has life and grows to take care of trees, lawns, flowers, vegetables and such things planted with their own hands. It is a place where the plants together with their friends and enemies have an intimate relation to the child personally; where the lessons are far more vital than anything …


A Comparative Study Of Degenerative Tissue, Homer Davis Jan 1897

A Comparative Study Of Degenerative Tissue, Homer Davis

Electronic Theses and Dissertations

Nutrition is the earliest and most constant of vital operations. So prominent is the nutritive apparatus of an animal that the animal has been likened to a moving sac, organized to convert foreign matter into its own likeness, to which the complex organs of animal life are but auxiliaries. In growth more material is used by the body-protoplasm that is expelled. Nutrition includes excretion i.e. the removal of spent material which is usually poisonous and which if allowed to remain in the body organism would impair nutrition in its fullest sense. The objects of nutrition are growth, repair, and propogation. …
