Pastures Of Western Kansas In Relation To Intensity Of Utilization In Past Years, Gerald W. Tomanek

Master's Theses or Doctor of Nursing Practice

Short grass pastures vary in their ability to produce forage for livestock consumption. One of the reasons for this difference is a variation in the degree of utilization in past years. Forage production of short grass ranges has been reduced to about one-half after only a few decades of improper grazing; therefore the problem of proper utilization is becoming more important every year (Forest Service, 1936). When the settlers first came to western Kansas they found an almost complete cover of native vegetation and during the first few years only a small portion of the range land was cultivated. With …

An Adaptation Of The Feulgen Reaction For The Staining Of The Salivary Gland Chromosomes Of Drosophila, Herman C. Inlow

Bachelors’ Theses

The discovering of the genetic value of Drosophila salivary gland chromosomes by Painter, Heitz, and Bauer in 1934 posed a problem of technique to the microtomist that is still being improved upon and widened. The staining of these chromosomes fer better study and to determine their properties, both chemical and physical, has been the object of intense research. This paper is the result of my work in connection with this subject.

Fusarium Conglutinens Variety Callistephi, Beach And Its Effect On The Chrysanthemum, Mary Heimick Palmer

Bachelors’ Theses

This thesis is the result of extensive research for the past year at Marquette University on Chrysanthemums. In particular, I refer to a specific problem, that of an attempt to ascertain with certainty the cause of a serious infection of Chrysanthemums. This treatise covers the procedure and methods used in discovering the actual pathogen, and my reasons for believing that this particular pathogen is Fusarium conglutinens variety Callistephi.

The Rh Factor: Recent Developments And A Study Of Its Incidence Among The Indians Of The Southwest, Earl B. Gerheim

Biology ETDs

The purpose of this study was to continue the work started in determining the incidence of the Rh factor among Indians of the Southwest and review the related literature. This paper will include the author's initial results in which 251 Indians were tested.

There is at this time no published account on the incidence of the Rh factor among the Indians of the Southwest; therefore, this is important from the standpoint of originality. The problem has medical importance in the role which Rh plays in transfusion and congenital hemolytic disease, otherwise known as erythroblastosis fetalis. The results will serve as …

A Cytological Study Of The Salivary Gland Chromosomes Of The Attached-X Variety Of Drosophila Melanogaster, Jack Schull

Bachelors’ Theses

The detailed study of -the salivary chromosomes of the Diptera has been of great importance in substantiating cytologically the theories of genetics. A noteworthy example of the importance of cytological study is the non-disjunctive phenomenon which has occurred on at least several occasions in the strain of Drosophila melanogaster. Bridges (1913) was the first to report nondisjunction of sex chromosomes which was an important confirmation of the chromosome theory. L. V. Morgan (1922) used the cytological study of the germ cells of Drosophila melanogaster to prove that there was no disjunction of the sex chromosomes in the attached-X strain.

A Comparison Of The Autonomic Nervous System Of The Cat And The Pigeon, William P. Mccarthy

Bachelors’ Theses

The purpose of this thesis is to describe the autonomic nervous system of the cat and pigeon and to compare them as to their structure. This comparison will consist in noting the differences and points of similarity between the two animals. The autonomic nervous system of the cat is more complex than that of the pigeon and for that reason the comparison will consist in pointing out the parts of the autonomic nervous system present in the cat, but which are not found in the pigeon. In noting the points of similarity only the most important will be treated.

Developmental Anatomy Of Descurainia Pinnata, Robert D. Spensley

Biology ETDs

This study is concerned mainly with the morphological development of Descurainia pinnata subspecies ochroleuca (Wooton) Detling, a member of the tribe Sisymbrieae and subtribe Descurainiinae of the Cruciferae. Although commonly referred to as Sophia by many botanists, this genus is otherwise known as Descurainia and sometimes partly included in Sisymbrium. D. pinnata is listed as Sisymbrium canescens in Gray's manual, as Sophia pinnata by Coulter and Nelson, as Descurainia pinnata by Kearney and Peebles, and as Sophia ochroleuca by Wooton and Stanley.

The Anatomical Differences Of The Tubers Of The Genus Dicentra, June E. March

Bachelors’ Theses

Gray (1878) described a number of the subterranean modifications of the stems. These can be distinguished from the roots since they produce regular buds and scale leaves.

A Survey Study Of The Intestinal Worms And Ciliates Of The Hog (Suis Domesticas), John F. Crowley

The Effects Of Various Concentrations Of Vitamin B1 On The Growth Of Amoeba Proteus, Walter J. Bo

Bachelors’ Theses

Thiamin or vitamin B₁ was first isolated in crystalline form from rice bran by Jansen and Donath in 1926 . Windous, Tschesche, Buhkopf, Laquer and Schultz in 1931 isolated the pure vitamin B₁ from yeast and established the emperical formula - C₁₂H₁₇ON₄Scl.Hcl .

A Study Of The Renal Vascular Supply In The Domestic Cat, Elizabeth Rosen

Bachelors’ Theses

Studies on the normal and abnormal vascularization of the renal vessels in the domestic cat (felis domestica) indicate the frequency of anomalies that occur, but in most of the studies it is the inferior vena cava that is most often recorded. Among the occasional references to several renal veins or arteries we have Huntington and McClure, Elmer Butler, Gaylord Bates, William Darrach, and C.H. Fortune. Yet no study seems to have been made of individuals of any particular class. A superficial observation seems to indicate a large number of cats used in the laboratory had multiple renal veins. Hence a …

Thrips Species Infesting Tomatoes And Other Host Plants Of These Insects In Northern Utah, Darrell R. Maddock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study has been to determine which species of thrips infest tomato plants and fruits in northern Utah, and to find out which other plants occurring in this area also serve as hosts for tomato-infesting thrips.

Because of the importance of tomato-infesting thrips to the canning industry, it was decided that more complete knowledge of the species of thrips which are found on tomatoes should be obtained. Because most thrips generally have been difficult to control, it was believed that a general knowledge of the plants on which these thrips occur would enable tomato growers to eliminate …

A Comparative Study Of Directed Laboratory And Lecture Demonstration As Methods Of Instruction In Teaching Botany To High School Students, M. Lucida Vorndran

Master's Theses or Doctor of Nursing Practice

A controlled investigation of green plants as the most important food factories of the world has been made in order to contribute more information upon the issue. Stated more specifically, the problems of this experimental study were the following: 1. To determine which of the two methods, if either, is superior as a procedure for learning. 2. To determine whether laboratory experiments are more effective than lecture-demonstration in training students to think clearly, to correlate and retain facts; and finally, to draw logical conclusions. 3. To determine, if possible, which method stimulated the greater amount of pupil interest.

Bio-Ecology On A Mixed Prairie Near Hays, Kansas, H. Leo Brown

Master's Theses or Doctor of Nursing Practice

A survey of the activity of wild animals in connection with range conditions and range management is greatly needed in western Kansas. To have a well-managed range one should have an understanding of the ecological factors which benefit or deplete the native vegetation that is essential for production of livestock. The impact of grazing, and the effect of changes in edaphic and atmospheric environment on the prairie have further emphasized the importance of a cover of grass in preventing erosion.

An Anatomical Study Of Cicer Arietinum, Mary Elizabeth Johns

Biology ETDs

This investigation was made for the purpose of studying the developmental anatomy of the primary axis of Cicer arietinum. Ontogenetic studies of the primary and secondary tissues of the root and stem, and the leaf primordia are included

The Stomatal Behvior Of Begonias And Its Relationship To Infection By Xanthomonas Begoniae, Eugene David Kitzke

Bachelors’ Theses

A leaf spot disease of begonias caused by a bacterium has been under observation and study at Marquette University for nearly a year. It brings up many interesting questions which need to be an­swered before the investigators can fully evaluate and determine correctly the relationships of this organism to the Begoniaceae. One of the questions, which has come up, was the problem of the mode of entrance. It is the purpose of this paper to deter­ mine the relation of the stomata to infection.

Histological Study Of The Small Intestine Of The Common Green Snake, Thamnophis Sirtalis, Robert George Stineman

Bachelors’ Theses

Although much work has been done histologically with the vertebrates, very little seems to have been done on the intestinal tract of the reptile. This is especially true of the snakes, despite the abundant sources of material. Reptiles are one of the first classes of vertebrates in which there is a distinction made between small and large intestine. Histology textbooks devote only a few lines to the histology of the reptilian small intestine. For this reason it seems that it would be worthwhile to make a detailed study of that portion of the intestinal tract immediately distal to the duodenum …

The Histology Of The Digestive Tract Of The Common Green Snake, Thamnophis Sirtalis 3. Esophagus, Janice Jean Mcfarlane

Bachelors’ Theses

This is the third in a series of investigations of the comparative histology of the digestive tract of Thamnophis sirtalis, the common green snake. Comparatively little recent work of this nature upon any of the class Reptilia, and especially upon the order Ophidia, seems to have been undertaken. Kendall(1940) makes no mention of Ophidia, but discusses briefly the digestive system of the lizard, limiting his treatment of the esophagus to a few lines. Cole (1941) has an equally short and general discussion of the digestive system of Thamnophis sirtalis, again devoting but a brief space to his discussion of the …

Atypical Conditions Of The Inferior Vena Cava, Mary F. Reagan

Bachelors’ Theses

Extensive dissection of various mammalian forms, expecially of man, the rabbit, and the cat has led to a recognition of a certain vascular pattern of the inferior vena cava which is typical for the group, It occurs so consistently that the occasional specimens which differ from it are of interest because of both their ontogenetic and phylogenetic significance.

The Feulgen Reaction Applied To Various Platyhelminthes And Small Ascarid Worms Mounted In Toto In Balsam Oil, Louise R. Russort

Bachelors’ Theses

The problem involved in this experiment was the application of the Feulgen Reaction to a number of flatworms and small ascarid worms, in an attempt to ascertain whether or not a practical staining technique, (showing clear differentiation of nuclear material, etc., from the surrounding cuticle and cytoplasm) -- may be developed, by staining and mounting them in toto. The Feulgen Reaction was used in this experiment, not as a specific indicator for thymonucleic acid, but rather as a cytological stain. Some attention will be focused upon the reaction's specificity, however, in the following discussion of the development of the reaction …

Some Technique Methods For Preparing Slides Of The Paramecium, Irene Padley

Bachelors’ Theses

Du Jardin (1835) was probably the first to recognize in protozoa, living substance. To this substance, he applied the word sarcode. In 1861, Max Schultze expressed the idea that sarcode and protoplasm are the same thing.

Making Permanent Mounts Of Fern Gametophytes, Gail Seeraphine Barczak

Bachelors’ Theses

One of the botanists first to grow fern gametophytes from spores whicch were sown on moist clay was Farlow (1874), a student of the famous botanist, DeBary, professor of Botany at the University of Strassburg in Germany. Farlow sowed the spores of Ptteris cretica var. albo-lineata on moist clay placed into small flower pots. Watering was accomplished from the top. There was no sterilization of the culture medium. The gametophytes of this fern were also grown under the same conditions by DeBary (1878). Steil (1919a) grew the prothalli of Ptteris sulcata and Ptteris cretica var. albo-lineata in the same manner …

A Cyto-Genetical Study Of Habronbracon Juglandis, Joan Meyer

Bachelors’ Theses

A cyto-gentical study was attempted of the males of the Ichneumonoid wasp Habrobracon juglandis (ashm.) The larval of this wasp are parasitic on the larval of a flour moth Ephestid kuekniella (zeller). The males of this wasp were disected and slides were made of the testes. Different staining techniques were used in order to determine which ones would give the best results.

The Development Of Bone In The Chick Embryo, Helen M. Koelsch

Bachelors’ Theses

The day by day development of the bone in the chicken embryo as determined by the fixing and staining of embryos for each twenty-four hour growth period during the time of greatest skeletal development, is the subject of this paper. The stage in the embryological history of the chick during which the most important phases of bone development occur was determined to be the period between the seventh and the sixteenth days of incubation. It is therefore the purpose of this investigation to give an account of the growth and development of the bones of the ordinary domestic fowl as …

Histology Of The Stomach Of The Common Green Snake, Thamnophis Sirtalis, Lois Doerfler

Bachelors’ Theses

This is another in the series treating the histology of the digestive tract of the reptile. Very little comparative work has been done on the digestive system as a whole and less attention has been paid to the stomach. Kendall (1940) and Cole (1941) devote a slight discussion to a general description of the reptilian stomach. The following report is a more detailed microscopic investigation of the anatomy of the stomach of one of the common species of snakes...

The Utilization Of Grasses And Forbs In Relation To The Intensity Of Grazing In The Mixed Prairie Near Hays, Kansas, Noel Runyon

Master's Theses or Doctor of Nursing Practice

The principal occupation of the inhabitants in the Great Plains Region is livestock farming. The problems confronting the farmers and ranchers of this large area are many and varied. Not the least of these problems is the one of a proper stocking rate for the various types of ranges in order to secure a maximum production with the least in capital outlay and range deterioration. Another problem that has presented itself in recent years is the one of revegetating thousands of acres of marginal and semi-marginal land so that mother nature may again heal the marks of erosion and bring …
