The Distribution And Utilization Of Agave In The American Southwest, Alvin Russell Grove

Biology ETDs

It is the purpose of this thesis to show in a comparative way the importance of Agave sp. for food, drink, fiber, etc., among various tribes comprising the American Southwest.

The problem is important from ethnological and ethnobiological standpoints. Through a study of man's attempt to utilize for food, etc., articles which grew at hand, one can better understand him. The methods of plant utilization show the effect of the environment on the man as well as his attempts to adjust himself to it or adjust the environment to himself. The problem, in addition, is an ecological one, showing the …

Bulletin No. 281 - Sorghums Varietal Tests In Utah, R. W. Woodward, D. C. Tingey, R. J. Evans

UAES Bulletins

Sorghums are not grown to any appreciable extent in Utah except in the Virgin River valley in the southwestern portion of the State. No experimental work on sorghum culture had been done prior to 1931 except on the dry land of Juab County near Nephi. Those early tests, discontinued after 1917, indicated that sorghums were poorly adapted to such conditions.

Numerous improved varieties have been produced since that time, some of which are adapted to relatively short growing seasons.

This bulletin will discuss the practicability of growing some of these varieties of sorghum in Utah and their economic value compared …

Bulletin No. 278 - Should Flax Be Grown In Utah, R. W. Woodward, D. C. Tingey, A. C. Dillman

UAES Bulletins

Flax has been considered as a possible crop for growing under irrigation in Utah because of its high acre return in some of the northern States. One of the functions of a State experiment station is to test new crops and varieties. A series of experiments , therefore, has been conducted in Utah to determine the yields of flax as compared with small grains both under irrigation and on dry lands. This bulletin report s a summary of the results of these experiments together with a discussion of comparative returns from flax and small grains.

Two types of flax, seed …

Relation Of Height At Withers And Chest Girth To Live Weight Of Dairy Cattle Of Different Breeds And Ages, H. P. Davis, R. F. Morgan, Samuel Brody, A. C. Ragsdale

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The size of a dairy cow is important from the standpoint of feed consumption and economy of production and also as an indication of the expected size of offspring. The ultimate disposal of dairy cattle is for beef, and the measure of returns is based upon size and condition. A method for the determination of the approximate weights of dairy females, where scales are not available, is needed. Measurements of dairy cattle which show development and skeletal growth by ages in relationship to weight are presented here for four different dairy breeds.

A Histological And Functional Study Of The Skin Of The Frog, Oscar Stern

Bachelors’ Theses

In recent years much has been written on the skin of the frog, however, it seems that little has been done to correlate the morphological and physiological aspects of the skin. The literature reveals that considerable work has been done on the common laboratory frog Rana pipiens.

A Study Of The Relation Of Temperature To Antibody Formation In Cold-Blooded Animals, Earl C. Mcdaniel

Biology ETDs

It is an established fact that when warm-blooded animals are inoculated with foreign protein, in a great many instances they become immune, due to the formation of antibodies specific for the protein injected. In warm-blooded animals the body temperature is constant. The question naturally arises as to what the situation would be with regard to antibody formation in a cold-blooded animal where body temperature is not constant; also what part, if any, the temperature of the body would have to do with the antibody formation.

In a careful review of the literature practically nothing could be found in having direct …

Bulletin No. 277 - A Study Of Utah's Winter Range: Composition Of Forage Plants And Use Of Supplements, A. C. Esplin, J. E. Greaves, L. A. Stoddart

UAES Bulletins

Range forage provides the foundation for the maintenance ration available for most sheep wintered in Utah. The nature and amount of supplemental concentrate or roughage needed with this forage to provide an adequate and efficient ration for sheep naturally depends on the nature and amount of range forage available. Present uncertainty as to the relative merits of the various available supplements originates largely through a lack of definite knowledge as to the composition and feeding value of the various range plants that go to make up the range-forage supply on the particular range in question.

The Utilization Of Food Elements By Growing Chicks. I. A Comparison Of Protein Concentrates From Animal And Vegetable Sources, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The effects of adding to a basal ration, protein concentrates from animal and vegetable sources were studied by means of growth and body-analysis experiments. 2. There was a small increase in the nitrogen content of the chicks fed the animal protein concentrate, but no differences appeared between lots with respect to their content of calcium and phosphorus. 3. The percentage rate of gain and the gain per gram of nitrogen fed were greater in the lot fed the animal protein concentrate. 4. The lot fed the animal protein concentrate retained more of the nitrogen fed, but less of the …

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.

Salivary Gland Chromosomes Of Drosophila Melanogaster And The Bar Duplication In The Heterozygous Fly, Gertrude H. Tromp

Bachelors’ Theses

in view or the fact that salivary gland chromosomes are being so thoroughly studied at the present time, it is interesting to notice that as early as 1881 Balbiani reported the chromosomes in the Chironomus fly. He interpreted the "bands" which are of such importance to the cytologists today, as disks of chromatic material. The achromatic material he called "zwischensubstanz" or as it is now termed the matrix. Leydig (1883) also worked with the Chironomus fly. He thought that the "bands" were similar to muscle fiber striation. Carnoy (1884) believed the chromosomes were hollow cylinders and the chromatin arranged to …

The Effects Of X-Rays Upon The Roots Of Zea Mays, Bernard Louis Wolfe

Bachelors’ Theses

Since. the discovery of X-rays by Rontgen in 1895, the majority of published papers dealing with the influence of these rays on plant life have considered their general effects on physiological processes including rate of seed germination and growth, respiration, and movements. A large number of investigators have worked on the morphological and cytological aspects while comparatively few workers have been interested in the histological effects of the stimulated tissues. The purpose of this thesis is to show the histological, morphological, and cytological effects of X-rays upon the root tips or the Zea Mays as well as the effects these …

The Histology Of The Stomach Of The Frog Rana Pipiens, Eugene Anton Kampmann

Bachelors’ Theses

The common grass or leopard frog, Rana pipiens, lives in or near fresh-water lakes, ponds, and streams, and is distributed over the North American continent except on the Pacific slope. The frog has both scientific and commercial value. Frogs legs are highly prized by the epicure. In the laboratory, the frog is used in elementary courses in zoology to illustrate the characteristics of the vertebrates. Holmes very clearly states the present scientific value of the frog, "For a long time the frog has been a favorite object for the study of animal structure and function. Probably no species except …

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 …

Cross-Section Anatomy Of The Male Frog (Rana Catesbiana) : A Transverse Section Through The Region Of The Eighth Vertebra, Arthur L. Guepe

Bachelors’ Theses

At the present time there does not exist a complete cross-section anatomical study of the common bull frog, Rana catesbiana. In fact, there has been very little mention in literature of any cross-section anatomy of any particular animal. However, there has been some work of this nature done in the study of human anatomy, especially the important publication of Eycleshymer and Schoemaker (1917), and in a small measure in the anatomy of the rabbit. This lack of literature on this certain topic, however, does not mean that the author had any intentions of presenting a complete cross-section study of …

The Identification Of The Tomato Mosaic Virus Prevalent In Utah, Ross D. Watson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Collections of tomato mosaic virus obtained from Utah and California produce a localized severe leaf and stem necrosis on Datura meteloides. After the streaked plant has stood sufficiently long to permit secondary growth to occur, a systemic diseased expression develops in a few of the plants. No reference to a similar development on Datura meteloides following inoculation with the tobacco mosaic virus was found in the literature.

An Economic Analysis Of Farm Tenure In The Uintah Basin, Utah, Glen B. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Before presenting an economic analysis of farm tenure in the Uintah Basin, it will be helpful to consider some aspects of the historical, economic, and social background of that portion of the region included in this study.

A portion of the Uintah Indian Reservation, which was created in 1861, was opened to white settlement under the homestead and townsite laws on August 28, 1905 after 103,000 acres of farming land had been allotted to individual Indians living on the reservation and 276,000 acres reserved for Indian grazing lands and timber reserve.

The Microflora Of Milk Drawn Aseptically From The U.S.A.C. Dairy Herd, Lewis W. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early studies on the bacterial content of milk were made mainly to satisfy the interest of people who wished to determine the various materials that contained bacteris. Soon the value of bacterial counts, as an indication of the general conditions of production, of handling, and of the keeping qualities of milk, became evident and bacterial counts were used to obtain information concerning these problems. Numbers of bacteria in milk have been used also in the studies of the desirable and undesirable changes in milk.

In the last few years our citizenry has been made more conscious of the presence and …

The Plankton Of The Bear River Migratory Waterfowl Refuge, Utah Seasonal Distribution Of Organisms, George Piranian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the summer of 1932, an investigation of some biological, physical, and chemical conditions at the Bear River Migratory Waterfowl Refuge, Utah, was begun at the Utah State Agricultural College to determine some of the factors governing the biological productivity of brackish-water marshes. Unfortunately, lack of funds made it impossible to continue work beyond the first season.

In 1936, the Wild Life Experiment Station at the Utah State Agricultural College appropriated a fund for a cooperative project between the Station and the Department of Botany at the same institution. This project, planned to be continued by various graduate fellows over …
