A Cytological Study Of The Ciliated Epithelium Of Nucula Castrensis Hinds., Dorothy Blumer
A Cytological Study Of The Ciliated Epithelium Of Nucula Castrensis Hinds., Dorothy Blumer
Electronic Theses and Dissertations
Ever since the latter part of the 17th century, when ciliary movement was first observed, the study of ciliated cells has been of great interest to biologists, particularly to physiologists. In 1713 Leeuwenhoek recorded some observations he made on ciliary activity, using his primitive microscope. A knowledge of the structure and function of ciliated cells is also of importance in that branch of medicine pertaining to disorders of the respiratory passages and the movement of the ovum in the uterine tubes. The bivalve molluscs have come to be the classical example for the study of ciliated cells, both because of …

The Effect Of Ultra-Violet Light Upon The Growth Of Zea Maize., W. H. Clashman
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 …
Hydrogen Ion Concentration In Lead Acetate Solutions., Emile Pragoff 1907-1991
Hydrogen Ion Concentration In Lead Acetate Solutions., Emile Pragoff 1907-1991
Electronic Theses and Dissertations
It shall be the object of this investigation to measure the hydrogen ion concentration in lead acetate solutions and to apply the measurements to the control of color in the preparation of chrome yellow pigments. Lead acetate solutions of high concentration, known as lead liquors, are used in the preparation of chrome yellows by precipitation with sodium dichromate. Since the color of the pigment is believed to be dependent on the hydrogen ion concentration of the lead acetate solution used, such a study is of interest to dry-color manufacturers and to users of chrome yellows. The methods now in use …

The Growth Of Wheat Seedlings In Solutions Containing Monopotassium Phosphate, Calcium Nitrate, And Magnesium Sulphate, Singly And In Pairs., Joseph Carmin 1895-
Electronic Theses and Dissertations
Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different burned plants were analyzed; they were found to vary with the soil in which the plants were grown as well as with the species of the plant and the special organ from which the ashes were obtained. A great number of minerals was found in the ashes. The question arose soon, which of these elements is essential to the …
Cooperative Marketing Of Farm Products In South Dakota, Wendell Frichiof Kumlien
Cooperative Marketing Of Farm Products In South Dakota, Wendell Frichiof Kumlien
Electronic Theses and Dissertations
Introduction: General Facts Underlying the Whole Problem of Distribution and Marketing of Farm Products Before entering into a detailed discussion of cooperative marketing of farm products as applied to South Dakota, I wish to briefly mention a few general historical facts which in a large part go to make up the background for the whole present day problem of distribution and marketing. 1. Pioneer America’s Agricultural Problems Mainly Those of Production During the period when our country was predominately agricultural, each farm produced practically everything it needed and was in the main self-sufficing. Each farmer produced his own wheat and …
The Relation Of Pyruvic Acid To Carbohydrate Metabolism., Sylvester Louis Schulte
The Relation Of Pyruvic Acid To Carbohydrate Metabolism., Sylvester Louis Schulte
Electronic Theses and Dissertations
It is known that carbohydrates on oxidation break into fragments which later are oxidised, or reduced, according as the conditions of the bodily functioning may favor, and it is in this process or reaction of the carbohydrate molecule that the formation of pyruvic acid probably takes place. From this point the pyruvic acid molecule on being fully oxidised would give the products carbon dioxide and water, and partial oxidation would give carbon dioxide and other products.

Motor Tests And Experiments In Light., Bennett Mattingly Brigman 1881-1938
Electronic Theses and Dissertations
This experiment was performed by the use of a Spectrometer using the customary methods of measurements usually adopted for this work. Method "A" The telescope having a Gaussian eyepiece attachment, the telescope's cross-hairs are illuminated and reflected upon the two plane faces of a prism in succession. The angle through which the telescope is turned between the first and second face equals 180 degrees – A, where A is the angle of the prism. Method "B" The Collimator so placed that the slit is illuminated by a flame it falls upon both faces, being divided by the edge of the …
