Notes On The Distribution Of Amphibia And Reptilia Of Ellis County, Kansas, Lawrence A. Brennan
Notes On The Distribution Of Amphibia And Reptilia Of Ellis County, Kansas, Lawrence A. Brennan
Master's Theses or Doctor of Nursing Practice
Comparatively little has been done concerning the listing or recording of the Amphibia and Reptilia of Ellis County, Kansas. What records there are of the species are for the most part unpublished. Early papers dealing with Kansas herpetology are few in number. Little has been done in Ellis and the surrounding counties, so there seems to be a need for such an ecological study as has been carried out in this paper “Notes on the Distribution of Amphibia and Reptilia of Ellis County, Kansas . " The objectives kept in mind in preparing this report have been to attempt to …

A History Of Wool Manufacturing As It Is Related To Wool Marketing In Utah, George Elwood Spencer
A History Of Wool Manufacturing As It Is Related To Wool Marketing In Utah, George Elwood Spencer
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
It has been advocated by many sheep raisers and individuals interested in the wool industry of Utah, that wool manufacturing should become a leading industry of this state. Factors which seemingly corroborate such contentions are readily apparent. Utah's annual wool clip ranges between eighteen and twenty-five million pounds of wool.(1)*. The state is located in the center of the Western range states where the bulk of the higher quality wool of this country is grown. A part of the marketing costs of freight, commission charges to a limited extent, and high storage costs could be decreased. These savings would result …
The Nature And The Development Of Starch Grains In Seed Plants, Slyvester John Siudzinski Jr.
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
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
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
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.
A Determination Of Nicotine In Tobacco, Raymond L. Boelter
A Determination Of Nicotine In Tobacco, Raymond L. Boelter
Bachelors’ Theses
Nicotine or nicotin, named from Jean Nioot who introduced the tobacco plant into France in 1565 is the characteristic alkoloid of the tobacco plant, Nicotiana tobacum, in all parts of which it occurs to the extent of from six tenths of one per cent, to four and eight tenths per cent.
The Inheritance Of Some Human Traits, Robert H. Crawford
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.

A Taxonomical, Morphological And Distributional Study Of The Utah Cyprinidae /|Cby Sheldon Phipps Hayes, Sheldon Phipps Hayes
Theses and Dissertations
The hydrography of Utah may be thought of as being roughly divided into two large general drainage areas--, the Colorado River draining the eastern halt and southern portion ot the state and the Bonneville Drainage encompassing the remaining part of it. Earlier workers have listed eight genera and fourteen species of minnows occuring in Utah. Of these this report includes seven genera and ten species found within the borders of our state.
Inheritance Of Resistance To Three Physiologic Forms Of Bunt In Ridit X Utah-Kanred Cross, Muhammad Ibrahim Shah
Inheritance Of Resistance To Three Physiologic Forms Of Bunt In Ridit X Utah-Kanred Cross, Muhammad Ibrahim Shah
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Bunt is a serious disease of wheat found in nearly all weat-growing countries of the world. In India the disease is more severe in the northern provinces than in the central and southern provinces as the temperature during planting time is favorable to the germination of the fungous growth in the northern part. In the central or southern parts, this is not the case. In the United States this disease causes heavy annual loss. The amount of smut in a field, or the percentage of smutted heads, is generally taken as an index of the reduction in yield or loss …
A Survey Of The Literature Dealing With The Calcium-Phosphorus Metabolism Of Normal Children, Albertine Appy Noecker
A Survey Of The Literature Dealing With The Calcium-Phosphorus Metabolism Of Normal Children, Albertine Appy Noecker
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this study is to collect and organize all data available to the investigator on the subject of calcium and phosphorus requirements for normal children. Since it is the business of nutrition to maintain health and prevent disorders, leaving the cure of disorders to the medical profession, this study deals with the calcium and phosphorus metabolism of normal children and avoids going into the pathological phases, taking up rickets and tetany only in so far as prevention is concerned.
If this study has any value it lies in the fact that the findings of investigators seem to be …

An Analysis Of The Expenditures Of South Dakota Counties From 1919 To 1935, George H. Phillips
An Analysis Of The Expenditures Of South Dakota Counties From 1919 To 1935, George H. Phillips
Electronic Theses and Dissertations
Three important studies are involved in an investigation of the cost of a governmental unit. These are expenditures, receipts, and indebtedness. The result of the three studies, properly coordinated, will yield what is known in public finance as "net expenditures" or, if the government under scrutiny should meet with favorable financial conditions, the final study might result in "net receipts". This study will consider only that phase of the cost of government which can be arrived at through an analysis of the gross expenditures of the counties of South Dakota. The term "expenditures" as used herein will, therefore, be taken …

Effects Of Overgrazing On The Mortality Of Desert Browse Of The Utah West Desert, Charles W. Menzies
Effects Of Overgrazing On The Mortality Of Desert Browse Of The Utah West Desert, Charles W. Menzies
Theses and Dissertations
During the summer of 1934 this investigation was conducted to determine the effect of overgrazing on the mortality of desert browse in the vicinity of the Desert Range Branch experiment station. Range lands of western United States have, as a whole been subjected to overgrazing. Utah has about 24 million acres of public acres of public domain that can only be utilized from grazing. An effort has been made to put this area under control. The "Taylor Grazing Act" passed by Congress June 28, 1934 is a big step in the direction of the control of this vast area of …
Probolitrema Tomalis Sp. Nov. (Trematoda) From Dasyatis Dipterura And Brachylaemus Virginianus (Dickerson) (Trematoda) From Didelphys Virginiana, Elsie Mae Graves
Probolitrema Tomalis Sp. Nov. (Trematoda) From Dasyatis Dipterura And Brachylaemus Virginianus (Dickerson) (Trematoda) From Didelphys Virginiana, Elsie Mae Graves
University of the Pacific Theses and Dissertations
The genus Probolitrema was established by Looss (1901) in recognition of the location of vitellaria and multiple testes entirely outside the extra caecal field in Anaporrhutum richardii Lopez (1888) which differentiated it from A.albidum Ofenheim (1900) with the vitellaria within and the testes partly within and partly without the intra-caecal field. Ofenhein had created the genus Anaporrhutum for the above two species because of their multiple testes. A.albidum was a new species described by him; his A.richiardii Lopez specimens he considered to be the same species as Distomum richiardii Lopez, described in detail by Monticelli in 1893. Looss pointed out …

Distribution Of The Human Blood Groups Among The Pueblo Indians Of New Mexico, Waldemar D. Schaefer
Distribution Of The Human Blood Groups Among The Pueblo Indians Of New Mexico, Waldemar D. Schaefer
Biology ETDs
The purpose of this paper is to show the distribution of the human blood groups among the Pueblo Indians of New Mexico. Upon reviewing all available literature concerning the distribution of the human blood groups, it was noticed that very little work had been done on the American Indian. Most of this work, although indicative of what really exists, cannot be accepted because of the insufficient number of Indians integrated and the failure to use an accepted standard method. In work that had been done previously, little attempt was made to secure a single homogeneous group of American Indians. Any …
Vegetative Changes In The Middle Rio Grande Conservancy District, Marjorie Van Cleave
Vegetative Changes In The Middle Rio Grande Conservancy District, Marjorie Van Cleave
Biology ETDs
This paper is concerned with the changes in the vegetation of the Middle Rio Grande Valley resulting from the lowering of the water table in the soil adjacent to the river. The Rio Grande has for a long time carried a heavy suspension of silt which is deposited as the river pursues its course southward to the Gulf of Mexico. The channel of the river has been raised as the result of this deposition until in many cases it has reached a level above that of the surrounding valley, and when this condition was attained the river diverted to a …
Studies In The Development Of Tissue In Helianthus Annuus, L., Theodore Riedeburg
Studies In The Development Of Tissue In Helianthus Annuus, L., Theodore Riedeburg
Bachelors’ Theses
The common sunflower, Helianthus annuus, L. is a member of the Compositae and a native of the Great Plains region of the United States. It is an annual herb, with a rough hairy stem three to fifteen feet high, broad, coarsely toothed rough heartshaped leaves three to twelve inches long and heads of flowers three to six inches wide in wild specimens and often one foot or more in cultivated plants. The plant is economically important, for its leaves are used as fodder, the flowers yield a yellow dye, and the seeds contain oil and are used for food. …
Some Factors Involved In The Manufacture Of Brick Cheese, George F. Jackson
Some Factors Involved In The Manufacture Of Brick Cheese, George F. Jackson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The flavor, quality and composition of market brick cheese varies greatly. Its moisture content often ranges from 37 to 43 per cent. The flavor may be similar to Limburger or it may even resemble that of Cheddar. Such a great variation in a specific food product tends toward disappointment for the consumer.
It is believed that a more uniform standard of quality for this product is needed to materially increase its consumption. Therefore, a detailed study of some of the factors involved in the manufacture of brick cheese may help to improve the quality and aid in determining a satisfactory …
Nuclear And Cell Division In The Root Tip Of Iris Versicolor, Mary Maxentia Mahoney
Nuclear And Cell Division In The Root Tip Of Iris Versicolor, Mary Maxentia Mahoney
Bachelors’ Theses
The writer found that very little work has been done on the somatic mitosis of Iris versicolor L. Some interesting accounts of karyokinesis in the root tips of some monocots have been written. Schaffner (1898) made a detailed study of nuclear and cell division in the root tips of the Allium cepa. He observed that the spindle originated from centrospheres, and that the most typical resting nuclei occured some distance back of the tip beyond the actively dividing region. In good stained material the resting nuclei had one or two large nucleoli and a very distinct chromatin net …

Basketball A Scientific Study Of Marquette Squads 1931-1934, Adolph L. Gorychka
Bachelors’ Theses
Basketball was invented by Dr. Naismith at the Springfield Y.M.C.A Training School in 1892. Since its invention, the sport has made great progress which now has the same seasonal appeal during the winter as football in the fall and baseball in the Spring.
Observations On The Gross Anatomy Of The Venous System Of Adult Chelonia, James S. Kain
Observations On The Gross Anatomy Of The Venous System Of Adult Chelonia, James S. Kain
Bachelors’ Theses
The turtle is a reptile belonging to the order Chelonia. Because it is so very abundant and its size so convenient it has been much used for class work and to a certain extent has been studied rather thoroughly by private workers. Each one, however, stressing his or her own particular point of interest especially, the turtle is attractive to students of Comparative Anatomy because of the fact that it has retained more of the primitive characteristics of the ancestral form from which the mammals are descended than any other readily available reptile.
Studies On The Anatomy Of The Arterial System Of The Turtle, Sylvester J. Schroeder
Studies On The Anatomy Of The Arterial System Of The Turtle, Sylvester J. Schroeder
Bachelors’ Theses
Turtles are reptiles in which the body is wide and short, and is enclosed in a shell composed of a dorsal shield, the carapace, and a ventral shield the plastron. The shell of three of the species is composed of large external, epidermal, horny plates. These latter consist, in the carapace, of the flattened ribs and the flattened trunk vertebrae which coalesce with overlying dermal bony plates, and are surrounded on the circumference of the shell by a series of marginal dermal bony plates; in the plastron they consist of exclusively dermal plates, there being no sternum. The carapace and …
The Effect Of The Nitrogen Fixation And Of Aeration Upon The Growth Of Yeast In Culture Media, Syrene C. Bernstein
The Effect Of The Nitrogen Fixation And Of Aeration Upon The Growth Of Yeast In Culture Media, Syrene C. Bernstein
Bachelors’ Theses
The subject of yeast has been widely studied from many viewpoints; we can find many bacteriological, physiological, and chemical papers on the subject. Besides the purely scientific work on yeast, there are numerous industrial investigations on this subject, since yeast growth and the products of yeast growth form the foundation for such important industries as the distilling, brewing, baking industries as well as commercial yeast manufacture. The effect of nitrogen fixation has been treated from all of these angles, scientific and industrial, and the investigations include the form in which the nitrogen is most easily assimilated, the manner of the …
