A Study Of Some Phases Of The Gametophyte Of Preissia Commutata Nees, Marion Steuber

Bachelors’ Theses

The beginnings of the exact knowledge of the Hepaticae dates from the work of Hofmeister, who in 1350 to 1362 published important investigations on them. He discovered the egg cell in the archegonium, traced the sperm to the surface of the egg and showed that it was fertilized by the sperm.

A Comparison Of Ths Digestive Powers Of Trypsin And Papain On Casein And The Effect Of Certain Mild Antiseptics On These Powers, Joseph E. Steker

Bachelors’ Theses

The purpose of this thesis is to study the effect of certain mild antiseptics, such as Benzoic acid, Boric acid, salicylic acid, Phenol, Cresol, Thymol, on the digestive action of the enzymes Trypsin and Caroid (papain). A thorough perusal of the literature reveals only a small amount of data dealing with the influence of common antiseptics on enzyme action. Because of the important uses of enzymes in industry and the need of antiseptics for protective action, this problem is of great importance. The author wishes to acknowledge the kind cooperation of Dr. John R. Koch, Head of the Department of …

Spermatogenesis Of The Albino Rat (Nus Norvegicus Albus), Norman A. Frankenstein

Bachelors’ Theses

This thesis deals with the inquiry opened by the fundamental discovery that the gamete nuclei, and hence, the two parents from which they are respectively derived, con­ tribute each a haploid or single group of chromosomes to the fertilized egg. Each act of fertilization doubles the gametic number of chromosomes; yet the number of characteristic of the species remains constant from generation to generation. Somewhere in the life cycle, accordingly, the diploid or somatic number must be reduced by one-half to the haploid or gametic number. The first explanation was that reduction took place by some process of degeneration or …

Histological Study Of The Structure Of The Testis Of Rana Pipiens, John L. Friedl

Bachelors’ Theses

All the living organisms, be they plant or animal, act as a unit which implies that the various anatomical and physiological systems are coordinated either for the benefit of the Individual itself or for the maintenance of the spe­cies. For convenience sake, the individual is divided into a digestive,. respiratory, circulatory, nervous, muscular, and skeletal systems; but there is one system which although of some value to the individual is primarily adapted for the production of other individuals, and this is the reproductive system.

Typical Women Characters In Three Of Gerhart Hauptmann's Naturalistic Dramas, Florence Cohen

Bachelors’ Theses

Innumerable papers dealing with various phases of Hauptmann's works have been written. Many, if not, all of them emphasize the story of his Dramas, the construction from the standpoint of naturalism, etc. Few, if any, however, have stressed Hauptmann as a character delineator, nor have they emphasized his treatment of the women. It is for this reason that the writer wishes to discuss three of Hauptmann 's Naturalistic Social Dramas emphasizing the treatment of the women with special regard to heredity and environment.

The Growth And Development Of Gemmae Of Marchantia Polymorpha L., Theodore F. Van Aacken

Bachelors’ Theses

Marchantia was discovered and studied around the middle of the seventeenth century. It was named Marchantia in 1683 by Jean Marchant in memory of his father. Later when Linnaeus completed his great work, Das Pflanzenreich (1786), he named the plant Marchantia polymorpha.

The Anatomy Of The Oyster, M.J. Rohlinger

Bachelors’ Theses

The phylum Mollusca manifests the following characteristics: bilateral symmetry; three primary germ layers; free-living and sessile; marine and fresh-water; a shell modified to form either a bivalve or a univalve which gives an appearance of segmentation due to rings of growth or arrangement of certain parts of the shell as is seen in the class Amphineura, this is only apparent metamerism because the Mollusca are considered to be unsegmented animals; a coelom poorly developed; a foot; a mantle cavity; well developed digestive, circulatory, excretory, and reproductive systems. When one inspects a Chiton, an oyster, a snail, an octopus, or a …

Topographical Anatomy Of Ostrea Virginica, Harry J. Barnett

Bachelors’ Theses

The oyster is important for at least three reasons. First, it is important to the zoologist; second, it is a food which has developed million dollar enterprises; and third, the oyster is a domestic resource for the pearl and its allied industries. The oyster is a bivalve Mollusk, having symmetry in the larval stage but losing it in the adult stage. It has one large adductor muscle, somewhat posterior from the ligament which holds both valves together. The left valve forms a deeper pit than the right one as it is in the left valve that the oyster lies. It …

Surgical Judgement, James M. Neville

Bachelors’ Theses

The title of this paper allows wide latitude of discussion, and shall, therefore, not be limited to any particular phase but rather to its broader and more general aspect; and yet, not wishing to sacrifice the concrete for the abstract, the writings and experiences of others shall be used freely so that this treatise may prove not only interesting but that it may also serve to emphasize the importance of good surgical judgement.

The Nature And The Development Of Starch Grains In Seed Plants, Slyvester John Siudzinski Jr.

Bachelors’ Theses

In spite of the importance of the starch grain from many points of view little work has been done on its nature and development. This fact is interesting since the nature and the development of the starch grain claimed a large share of the attention of the early workers. They observed and described the starch grains from the earliest days of the compound microscope. It was then observed that starch from the different plants showed in many cases marked differences with regard to size, shape and structural markings of the individual grains.

Color Reactions As An Aid To Seed Indentification, Carlton Leo Schmit

Bachelors’ Theses

Plants have long been classified according to their physical likenesses and structures. To sort plants according to such a basis, a botanist uses a key. In most cases, these keys are based on the flower or fruit of the plant. Sometimes there are disadvantages in using these structures, because usually they are only present for a short portion of the year. In a few cases, the seeds or fruits of plants have been used as a basis of classification as, for instance, in the Umbelliferae, Alismaceae, and Bidens.

The Weather Effect On The Characteristic Protein Values In Wheat, Mary Margaret Murphy

Bachelors’ Theses

Scientific investigation has proved conclusively that the protein content of the wheat kernel is the most important factor in determining the quality of the flour obtained. A high protein wheat is used for flour for bread making, and a low protein wheat for pastry flours. The quality of the protein must be determined by baking experimental loaves.

The year 1934 was a year of drought. In all parts of the country the wheat crops were affected by the lack of rainfall; hence, the protein value of the wheat must necessarily have been affected in some manner. The United States Department …

The Circulatory System In The Extremities Of The Domestic Cat From A Gross Anatomical Standpoint, Harold Liebenstein

Bachelors’ Theses

The mammalian circulatory system serves the prime purpose of furnishing the body with food to carry on its functions. The domestic cat is closely related anatomically and physiologically to the human being, which makes it an excellent animal for laboratory work or experimental purposes.

Whither Marriage?, Marguerite Irmgard Reuss

Bachelors’ Theses

This thesis has a threefold aim. I. The writer considers whether marriage as opposed. to promiscuity is necessary for the stability of the family and or the nation. II. The writer then aims to decide in the light of experience which theory of marriage among selected pre-Christian. peoples was the best from the standpoint of family and national stability. III. The writer then aims to assay modern theory of marriage to determine whether it corresponds with the theory of marriage found in Part II to be the best for family and national stability.

The Inheritance Of Some Human Traits, Robert H. Crawford

Bachelors’ Theses

Although the proper collection and observation of necessary data with reference to the application of Mendel's laws of heredity to man has been brief, it has disclosed evidence significant enough to make it appear highly probable that many of the characters in man follow these laws as well as do the traits of lower animals.

The object of this thesis was to determine whether or not certain human traits were inherited, the mode of their transmission from parent to offspring, and, if possible, the establishment of any proof of linkage in the human line.

Frederick Jackson Turner: Historian Of The West, Dorothy Kleiman

Bachelors’ Theses

Turner was born on November 14, 1861, at Portage, Wisconsin. He was born in that section of the country which in his works he interpreted as having produced the real foundation for the development of American life. No outstanding events occurred in the early life of Frederick Turner, or at least no record has been made of them. One may assume his life was very similar to that of any normal, happy individual. It can be said that the eventful later years of his life overshadowed those earlier days. For beginning with the year 1884, Turner's life proceeds through progressing …
