A Comparative Study Of Dehydration And Infiltration, Jane C. Mahar

Bachelors’ Theses

Dehydration is the process of removing water from tissue which has been fixed and hardened. It is a necessary step for the Infiltration of paraffin. If the dehydrating agent is not a solvent of the paraffin, it is necessary to use a solvent first and then infiltrate with paraffin. Dehydration, according to Sass (1940), has some washing action besides making the material firm and, in some cases, hard and brittle. When Bouin’s fixing fluid is used, ethyl alcohol is the solvent used in removing the solution and in washing the material. Dehydrating agents which possess hygrosopic properties are those most …

Heterothallism In Schizophyllum Commune, Lois G. Wilbershide

Bachelors’ Theses

For many years, workers have been striving to arrive at definite conclusions in regard to heterothallism in a great variety of plants. Much work has been done and there are many instances where heterothallism has been established and confirmed. Yet, in regard to Schizophyllum commune, few investigators have studied this phenomenon. However, much work of a different nature has been done on Schizophyllum since 1719 when attention was first called to this fungus partly because of the peculiar split character of the gills. It has been collected, classified, and worked on since that time, but the greater share of the …

A Study Of The Respiratory System Of The Sparrow (Passer Domesticus), Ben Peter Arnowitz

Bachelors’ Theses

The respiratory mechanisms of birds, unlike that of mammals, are definitely adapted to the function of flight. Because of this added adaptation, we should expect, therefore, some morphological and perhaps even embryological, physiological, and histological differences. An example of a morphological difference between birds and mammals is the intricate system of air-sacs that are present in birds. This remarkable feature is probably the reason why birds are able to fly as they do.

In this thesis the writer has used the sparrow (Passer domesticus) for the basis of his experiments. This particular bird was chosen in preference to …

Some Physical And Chemical Properties Of Wheat Starch In Relationship To The Maturity Of The Wheat, Claude W. Bice

Master's Theses or Doctor of Nursing Practice

Wheat is one of the most valuable of economic plants and is grown extensively throughout the world. Because of the unique chemical and physical properties of its gluten, wheat is superior to all other cereals for bread making. Its high starch content provides a tremendous source of energy as a food, as well as filling certain industrial starch needs, especially in textile manufacturing . The present study on properties of immature and mature wheat starches should be of inestimable worth for evaluation of damaged wheats for starch production, as well as for yielding fundamental information which may facilitate the use …

Population Size And Longevity Of Males And Females In Drosophila, Kathleen M. Murphy

Bachelors’ Theses

The two ever present instincts of man are self-preservation and the propagation of the race. At the beginning of one’s life this urge to survive is wholly unconscious but later on this will to live Is supplimented within the individual as a definite conscious search for longevity. Awareness to this inherent and universal desire to live is evidenced by the sought after services of the physician or doctor; the presence of civil law with the law courts and many other protective establishments. This conscious awareness to the possibilities, no matter how slight, of extending or at least maintaining life has …

Studies Of The Excretory System Of The Passer Domesticus, James Julian Stout

Bachelors’ Theses

In past years and in recent years most animals have been made a subject of study. However, very little or no research has been made on the most common of all birds, the English Sparrow. This thesis will endeavor to take up the study of the excretory system of the Passer Domesticus. In most animals the excretory organs are the kidneys and the skin, which pass of nitrogenous and other waste matters from the body. I will take up the main organ of this system the kidney at this time, with a histological study of the ureter, and leave the …

A Study Of The Digestive System In The Sparrow (Passer Domesticus), Henry Joseph Wisniewski

Bachelors’ Theses

The digestive tube proper of the Sparrow beings with the Oesophagus. This is a soft tubular organ which serves to convey food rapidly from the pharynx to the stomach. It extends along the median ventral margin of the neck lying dorsal to or to one side of the trachea. Posteriorly, at the base of the neck and shortly in front of the sternum it broadens slightly and gives rise to a dilated region of the oesophagus, namely the Crop, "whose secretion serves to moisten the food or even to initiate digestion." In larger birds as in the pigeon, the crop …

This phenomena has often been referred to as produced by incomplete nuclear division.

The Influence Of Dowicide A On Drosophila Melanogaster, Helen Mary Dore

Bachelors’ Theses

Drosophila melanogaster plays a far greater part in science than man at first realizes. A study of their heredity makes it possible to develop laws of human here­dity and with this knowledge, thus provide for the better­ment of mankind. Considerations which lead to the choice of the fruit fly, Drosophila melanogaster, in experimentation are briefly the following: (a) its small size which makes, it convenient to keep; (b) its short life cycle; and (c) the ease with which it can be cultivated. Since fruit flies are so important to science, it follows that it is also important that a …

The Biological Effect Of An Invisible Radiation On The Drosophila Melanogaster, Leo C. Massopust Jr.

Bachelors’ Theses

In a series of investigations, Massopust describes various effects he obtained with an invisible radiation which he called infra-red. The results he obtained seemed to indicate that this radiation might have some effect on development and growth. Hence, the Drosophila Melanogaster was chosen for experimentation to ascertain whether or not the invisible radiation he used would produce mutations. Personal communications from this author disclosed that up to the present writing he has not been able to establish definitely that the radiation lies somewhere in the infra-red band of the electro-magnetic field. He does, however, favor the interpretation that it is …

The Comparative Difference In Skeletal Structure Of Two Strains Of The Mus Musculus, Pasqual A. Capitanelli

Bachelors’ Theses

Father Raymond H. Reis, S.J., and Robert A. Littleford, Ph.D., both of the staff of Marquette's University Zoology department, while working upon an experiment in the feeding to the common house mouse, "Mus Musculus", noted that in the two strains of mice that were used, the white variety of mouse was a trifle larger than the black variety, but that their weights were identical. They suggested the possibility of a skeletal difference that seemed to be most prominent in the head of the mice.

A Study Of The Relationship Existing Between Certain Insects And Some Native Western Kansas Forbs And Weedy Plants, Carl Theodore Brandhorst

Master's Theses or Doctor of Nursing Practice

To the casual observer perhaps no sight could be more commonplace than that of an insect alighting upon a Kansas sunflower. But the relationship which exists between plant and insect is a matter which is often unknown even to the specialist. And yet a lack of understanding of these relationships has at times resulted in inconvenience, loss and even in calamity. To determine the relationship which certain insects bear to some of our native western Kansas forbs and weedy plants is the purpose of this study.

A Study Of Fluctuations In Coyote Numbers And Possible Causes, Sherwin B. Griswold

Master's Theses or Doctor of Nursing Practice

This paper reports the findings of a study of coyote numbers, with particular reference to fluctuations, their periodicity, if any, and their possible causes. In order to answer these questions studies of bounty payments were made in four centrally located counties of Kansas. The counties selected for this study were Ellis, Russell, Edwards, and Harvey. The location of these counties is shown in figure I on page 5. A record of these bounty payments was secured by checking through the records in the office of the county clerk of these counties for all years in which records were on file.

The Histology Of The Duodenum Of Thamnopsis Sirtalis, Harvey William Lyon

Bachelors’ Theses

The problem directly concerned is the histological study of the duodenum In Thamnopsls sirtalls, the common green or garter snake. The gross anatomy has been worked out In Reptilian forms and shows great variations, whereas very little work has been performed in the histology of the digestive organs. Some study has been made In other Reptilian forms such as the lizzard family but the knowledge of their histological structure is limited. Therefore if the gross anatomy differs in various forms, so may the histology differ also. It is the problem then of this thesis to investigate this subject and determine …

An Experimental Attempt To Modify The Sex Ratio Of Drosophila Melanogaster, Herman Weingrod

Bachelors’ Theses

Sex control has been defined as the science of producing male or female offspring at will by artificial means. Because of the far reaching consequences of such a technique, man has always had a strong desire to control the sex of his offspring. The ancient Egyptians attempted it by means of magic, while the old Hebrew Talmud offered suggestions for its practice based on practical experience. The problem as such forms part of the folklore and superstition of many ancient races and peoples.

The Anatomy Of The Stem, Root And Leaf Of Dennstaedtia Cicutaria Moore, William J. Weishar

Bachelors’ Theses

The work in plant anatomy up to 1874 was brought together and added to by De Bary (1884) in his memorable work, the Comparative Anatomy of the Vegetative Organs of the Phanerogams and Ferns. Several years later, Van Tieghem (1886) presented the groundwork for the stelar theory to explain the fundamental structure of the stem and root axis of the plant. Since that time the anatomy of the Pteridophytes has been the object of Increased interest and study.
