Taxonomix Study Of The Betulaceae And The Fagaceae Of Milwaukee County And Vincinity, Chalres A. Guenther
Taxonomix Study Of The Betulaceae And The Fagaceae Of Milwaukee County And Vincinity, Chalres A. Guenther
Bachelors’ Theses
The study of the Betulaceae and the Fagaceae in Milwaukee County and the immediate vicinity, taxonomically and from the standpoint of distribution presents an interesting problem. The family Betulaceae (Birch Family) comprises 11 species and 3 varieties, 8 species of which are arborescent. One genera is sometimes referred to as being arborescent in this vicinity, but since the author does not consider a lower growing shrub arborescent, he has excluded it from the classification of trees but has in the following discussion treated it as a shrub. The family Fagaceae (Beech Family) which comprises 8 species of which one is …
The Native And Cultivated Gymnospersm Of Eastern Wisconsin, Mary Stapleton
The Native And Cultivated Gymnospersm Of Eastern Wisconsin, Mary Stapleton
Bachelors’ Theses
Since the late years of the nineteenth century, botanists have grouped all seed-bearing plants into two main divisions, those with no seed cases, that is with naked seeds, end those the seeds of which are enclosed in a husk, pod, or other covering. The former are Gymnosperms; the latter Angiosperms.
Study Of The Tissues And Tissue Development In The Leaf And Stem Of Lycium Halifmifolium, L., Charles A. Troxel
Study Of The Tissues And Tissue Development In The Leaf And Stem Of Lycium Halifmifolium, L., Charles A. Troxel
Bachelors’ Theses
The Matrimony-vines are shrubs with usually spiny branches, rigid in some species, slender and arching or procumbent in others, with small and rather narrow, usually grayish green leaves, and dull-colored whitish, purplish, or violet flowers and scarlet, rarely yellow or black, berries. Most of the species are tender but Lycium halimlfollum, L. chinense, and also Lycium turcomanicum and L. ruthenlcum are hardy and thrive in the north temperate regions.
The Effect Of Theelin Upon The Growth And Development Of The Genital Tracts Of The Female White Rat, Robert H. Grogan
The Effect Of Theelin Upon The Growth And Development Of The Genital Tracts Of The Female White Rat, Robert H. Grogan
Bachelors’ Theses
This paper has been designed to meet the requirements of a bachelor's thesis. The main substance of the thesis is a reiteration of some of the work done by other men in the field of ovarian hormones with some original work on the part of the author. I have endeavored to prove that theelin controls, to some extent at least, the development of the genital tracts of female white rats. Especial care was taken to follow out in detail the methods used by Doisy and his associates in similar experiments so that I would have a criterion by which to …
Bird Studies Of The Bear River Marshes, Ernest W. Parkinson
Bird Studies Of The Bear River Marshes, Ernest W. Parkinson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The establishment of the Bear River Bay Bird Refuge has created for the state of Utah an immense and valuable biological field, a veritable paradise for naturalist and sportsman alike. The naturalist wants a place to study wild life and the sportsman desires game. With the proper control of open seasons on wild fowl the hunting instinct and incentive for the sport should be satisfied for the sportsman. To the naturalist this region will open up bountiful treasures of knowledge that is to be gained only by intense and prolonged scientific study.
A Critique Of Some Of The Metabolic Changes In The Mucosa Of The Alimentary Tract, Anthony Sanfelippo
A Critique Of Some Of The Metabolic Changes In The Mucosa Of The Alimentary Tract, Anthony Sanfelippo
Bachelors’ Theses
Among the many clinical conditions found in human beings, by both physician and surgeon, metabolic changes in the mucosa or peptic ulcer, as they are commonly known, stand out prominently from a purely scientific point of view, because of the divergent views brought forth during the past hundred yea.rs by even the ablest men. Peptic ulcer is a condition which manifests itself by a disturbance of the alimentary and digestive tracts, locally shown by an erosion of the devitalized cells of the mucous membrane.
A Morphological Study Of Daphniidae, Stanley E. Zawodny
A Morphological Study Of Daphniidae, Stanley E. Zawodny
Bachelors’ Theses
Th importance of fresh-water organisms is usually underestimated, especially by the very people who live near bodies of fresh-water and who thus can observe such organisms throughout the year. It is really easier to study minute life forms than it is to study larger organisms, for the former can be examined under all kinds of conditions as experiments are performed upon them. The purpose of this thesis is to give a short survey of the chief type among the fresh-water, Crustaceans, with special reference to morphology.
Heredity In Twinning, Dolores M. Kauffung
Heredity In Twinning, Dolores M. Kauffung
Bachelors’ Theses
Identical twins have been tn basis for a large amount of the evidence produced by scientists in upholding the contention that heredity is stronger and more important than environment.
It has been the purpose of this paper and the intention oi' the author to develop this theory and to attempt to discover how far heredity really affects the individual and. to what extent it may be influenced by environment.
Parasitology: With Special Reference To The Frog, Leo M. Boxer
Parasitology: With Special Reference To The Frog, Leo M. Boxer
Bachelors’ Theses
Prior to the middle of the sixteenth century the knowledge of parasites, their habits, life-histories and forms as limited to a few external parasites and a few parasitic worms. Previous to the discovery of, and knowledge gained by, the study of microscopic parasites, and the effects produced by them, nearly all diseases were thought of as some sort of punishment for sins committed.

Inheritance Of Resistance To Loose Smut (U. Tritici) In Certain Wheat Crosses, Bion Tolman
Inheritance Of Resistance To Loose Smut (U. Tritici) In Certain Wheat Crosses, Bion Tolman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
During recent years the principles of Mendelism have been used extensively in the production of the new types of plants possessing resistance to various diseases. Results of this mode of attacking the disease problem have been very favorable. Old varieties are gradually giving way to newer types equal to or exceeding in quality and productivity as well as possessing resistance to one or more diseases.
Loose smut (U. tritici) in wheat, while not as serious a problem in Utah as the covered smut (T. tritici), according to Tapke (14) has caused an average annual loss of between 50,000 and 100,000 …

The Silvan Flora Of The White Rock Lake Region With Reference To Soil Types, Landon H. Baker
The Silvan Flora Of The White Rock Lake Region With Reference To Soil Types, Landon H. Baker
Field and Laboratory
White Rock Lake, lying at the east border of the City of Dallas, has been the focus of considerable biological study during the past few years, and the writer has been especially interested in the trees growing in the region. In this connection the question arose as to whether or not a correlation might exist between the species of woody plants found in the locality, and the physical and chemical structure of the various soils of the vicinity. The recently completed Soil Survey of Dallas County offers data upon the origin and nature of these soils, and these have been …

The Comparative Anatomy Of The Kidneys, Edward Silberman
The Comparative Anatomy Of The Kidneys, Edward Silberman
Bachelors’ Theses
Most of the Information which I have been able to amass has been taken from text books dealing with the kidney as an excretory organ only. My bibliography, therefore, covers a rather limited field. In it there will be found no articles in the various journals as my endeavors to find any such articles on my particular subject have not met with success. My thesis does not only contain a comprehensive account of the kidney, its weight and size, but also an account of its shape, size and correlation in growth and size to the age and weight of the …
Contributions To The Anatomy Of The Mature Larva Of Papilio Polyxenes Fab. (Lepidoptera: Papilionidae), Ernst J. Dornfeld
Contributions To The Anatomy Of The Mature Larva Of Papilio Polyxenes Fab. (Lepidoptera: Papilionidae), Ernst J. Dornfeld
Bachelors’ Theses
Thia study was undertaken with the purpose of gathering more comprehensive information on the larval anatomy of a typical member of the lepidopterous family Papilionidae. Except for investigations dealing with the osmeteria, literature on the general anatomy of this otherwise well known family is very scant. Because of the relatively small number of specimens that were available for study, this paper has been limited to a discussion of the external anatomy and of the gross . morphology of the digestive tract, the urinary system, the silk glands, and the mandibular glands. Important papers in which these structures have been …

Autobiography Of Proteins In Nutrients, Marguerite Jones
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, …

An Economic Study Of The Food Habits Of The Ring-Necked Pheasant In South Dakota, H.C. Severin, South Dakota Department Of Game And Fish
An Economic Study Of The Food Habits Of The Ring-Necked Pheasant In South Dakota, H.C. Severin, South Dakota Department Of Game And Fish
Natural Resource Management Faculty Publications
The economic status in South Dakota of the ring-necked pheasant (Phasinus colchicus torquatus Gmelin X Phasianus colchicus colchicus L.) has turned out to be a controversial matter of no small importance with the citizenry of the State. This bird was introduced into South Dakota mainly thru the efforts and funds of the State Department of Game and Fish, and thru this department the pheasant was protected form slaughter by hunters, and permitted to multiply. When it was believed that the pheasants hasd established themselves in a county and multiplied sufficiently to warrant an open season , such an open season …

Origin Of The Limb Musculature In The Mouse., R Wendell Coffelt
Origin Of The Limb Musculature In The Mouse., R Wendell Coffelt
Electronic Theses & Dissertations
One of the most important and much disputed questions in the field of developmental anatomy is the role the myotomes play in the development of the limb musculature. At present there are two explanations advanced concerning the development of the limb-musculature in mammals. The first is that limb-buds arise as local thickening of the somatopleure, which becomes filled with a homogeneous syncytial mesenchymal tissue, that later becomes innervated with muscle-buds from the myotomes and with blood vessels, and nerves from the trunk of th embryo. The second method explained as to the origin of limb muscles is that they are …
Trichomonas Fulicae Sp. Nov. From Fulica Americana, Elizabeth G. Lash
Trichomonas Fulicae Sp. Nov. From Fulica Americana, Elizabeth G. Lash
University of the Pacific Theses and Dissertations
Numerous trichomonad flagelletes from the intestines or various birds have been described; but as fas as the writer has been able to discover, none from the intestine of the coot, Fulica americana. Martin and Robertson (1911) described Trichomones eberthi and T. gallinerum from the caecum of fowls; Kotlan (1923) described Tetratrichomonas avatis from the caecum of ducks; Tyzzer (1930) described flagellates from the ruffed grouse.
However, the species described by the above authors are quite different from Trichomonas to be described in this paper. This organism is definitely a member of the genus Trichomonas since it possesses the distinguishing characteristics …
