The Spinal Nerves And Spinal Cord Of The Frog, Laverne A. Penn

Bachelors’ Theses

The common grass frog, Rana pipiens as wall as the bull frog, Rana catesbiana have served during many decades as material from which both the student of zoology and the investigator in biological problems have gathered valuable information about the anatomy and physiology of the common systems. Among these systems the central, peripheral, and sympathetic nervous system plays a coordinating role, because of the ramifying nature of its organization. It is the purpose of this thesis to investigate the gross and histological structure of these branches known as spinal nerves. When one inspects the literature on the nervous system of …

The Lungs And Respiration In The Frog, Peter P. Strassburg

Bachelors’ Theses

In a wide sense, respiration is sometimes defined as the gaseous exchange constantly taking place between an organism and its environment. Essentially it is concerned with the intake of oxygen and the output of carbon dioxide but it also includes any other gas exchange that might occur. Small organisms take oxygen directly from the air or from the watery medium surrounding them into all parts of their structures. They also give off carbon dioxide from all their parts directly into the surrounding medium. They can do this successfully because they are small enough to have every cell in direct or …

Pancreas Of The Frog, Henry C. Boyer

Bachelors’ Theses

The pancreas has long been a subject of interest and speculation. It forms a favorable object for the study of secretory cells in general and has been used by various investigators who have studied the minute structure of the pancreas cell in relation to the secretory processes. Besides being a very active digestive gland it is the source of insulin; so that it is not surprising to find a vast amount of literature on the double function of the pancreas in general.

The Spleen Of The Frog, Clifford F. Moran

Bachelors’ Theses

Although we of today are living In a relatively advanced state of civilization, there still remains to be solved by man many familiar mysteries. These are found not only in the physical order but in the chemical and biological as well. It seems that the greater strides man takes toward the solution of his difficulties, the more other ones crop up to plague him. With the conquering of such deadly diseases as Diphtheria, Malaria and Scarlet Fever, man once dared to dream about a universe free from sickness. Yet today we find that three others have arisen which are causing …

The Gross Anatomy And Histology Of The Brain Of The Frog, George Howard Klumb

Bachelors’ Theses

The histology of the frog brain has been discussed at length in many sources, thus this work will be in the nature of a review of the previous material. However, all the work will be done on the actual sections of the frog brain, and the histological discussion will be preceded by a discussion of the gross anatomy, both internal and external; and the whole will be preceded by a short historical preface.

A Proximate Analysis Of Some Wisconsin Grown Varieties Of Soybeans, Herman Paas Jr.

Bachelors’ Theses

Within the last ten years there has been a constantly growing demand for soybeans. This demand is a result of the many new uses to which the by-products of the bean have been put. At present there are many varieties of soybeans on the market and each of these varieties have different compositions and hence have different qualities. Chemists are working on these different varieties and are trying to find the variety that is best suited for certain purposes. Wisconsin, which is primarily an agricultural state, will be among the leaders in raising the soybean. The purpose of this investigation …

Bulletin No. 275 - Types Of Farming In Utah, Marion Clawson, Walter U. Fuhriman, George T. Blanch, W. Preston Thomas

UAES Bulletins

A large portion of the agriculture of Utah, outside of the desert range areas, is characteristically heterogeneous rather than homogeneous in character. Marked differences in size of farm, in crops grown, in livestock kept, in yields, and in farm organization occur within short distances. This diversity is due in large measure to differences in soil, elevation, topography, and other physical features and to climatic characteristics such as amount, kind, and distribution of precipitation and length of growing season. The physical and climatic features are the chief determinants of the amount of water potentially available for the irrigation of the crop …

The Influence Of The Shoreline, Rivers And Springs On The Settlement And Early Development Of Texas, Ellis W. Shuler

Field and Laboratory

A comparison of early colonial settlements in New England and Texas during the middle of the eighteenth century shows a decided contrast in their locations. In New England the colonists settled along the coast, in Texas along a line roughly parallel to the coast but about one hundred miles into the interior. This distribution, coast line and interior, is all the more striking since in Florida and the West Indies the Spanish colonists, just as the English in New England, settled along the sea margin.

Transportation Adjustments To Topography In Dallas, Texas, Edwin J. Foscue

Field and Laboratory

The outstanding physiographic feature of Dallas County is the White Rock Cuesta, which marks the western edge of the Austin Chalk limestone. Immediately below the chalk lies the easily eroded Eagle Ford Shale, hence the contact between the two strata is clearly marked by this westward facing cuesta, which extends from the southwest corner of the county to the middle northern border. The Trinity River, an antecedent stream, has cut a gap through the cuesta about midway between the northern and southern boundaries of the county…. The gap through the cuesta, and the narrowing of the Trinity River flood plain, …

Bulletin No. 269 - Farm Versus Village Living In Utah, Joseph A. Geddes

UAES Bulletins

This is the second of a series of bulletins based on a study of Utah village life which was begun in 1927. The purpose of the investigation was to determine, under prevailing conditions, whether for farm people farm-living is less desirable than village-living. Four type villages were selected in as many counties for field studies.

Bulletin No. 257 - Factors Promoting Positive Health In School Children, Almeda Perry Brown

UAES Bulletins

It is necessary only to observe groups of rural children to become convinced that too many of them are deprived of their rightful heritage of positive health.

Why children playing together, working together, under conditions which apparently vary but little, should exhibit such wide variation in health conditions, is a question of vital importance to all concerned with the care of children.

It was with the hope of finding some of the causes behind these variations that the present study was initiated. That the problem is complex and intricate was fully realized, and no hope was entertained that its solution …

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 …

Contributions To The Anatomy And Physiology Of The Heart In The Turtle, David J. Twohig

Bachelors’ Theses

The heart in any animal, and especially in higher animals, is an important organ. It is the purpose of this paper to consider such an organ from the anatomical and physiological basis as it exists in the turtle.

The turtle was chosen as the subject for many reasons. The first one of these reasons was because the heart of the turtle closely.resembles the most complex of hearts in structure and action. The second was because the heart is quite typical of the members of Class Reptilia. The third reason was because the speciments are readily obtainable.

Contributions To The Anatomy Of The Aortic Arches Of The Acanthias Vulgaris, Wendell Corwin

Bachelors’ Theses

The spiny dogfish is a small shark that averages about two feet in length and three pounds in weight. It is called spiny because of the presence of a prominent spine on the boarder of each dorsal fin. The species has a wide distribution in the North Atlantic, occurring plentifully on the American and European shores, as well as in the Mediterranean Sea. The fish swim in enormous schools and are constantly in motion. The dogfish has no economic importance but is universally used for dissection in the zoological laboratory.

The Vitamin A Content Of Skimmilk, Standardized Milk, And Cream From Different Breeds Of Cows, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A study was made of the vitamin A content of skimmilk, of milk standardized by the addition of separated milk, and of cream. Rats whose body stores of vitamin A had been depleted by being fed a vitamin A deficient ration were fed either skimmilk, standardized milk, or cream as a source of vitamin A. Approximately 750 rats were used in nine experiments. From the results of these experiments the following conclusions were drawn: (1) that the vitamin A content of milk is associated largely with the butterfat and that separated milk containing a small quantity of fat contains only …
