Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy Jun 1951

Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy

Theses and Dissertations

During the period of October to April of the winter of 1950-51, an ecological study was undertaken of a population or passerine birds wintering in a segment of the Utah Lake Shore. Available winter weather data indicated that although such factors as precipitation, temperature, and wind may often be severe, they are not critical enough to prevent a fairly large population of passerine birds from spending the winter months in the study locale. Five fairly distinct plant communities can be recognized in the area. There is evidence which indicates that certain passerine bird species are especially dependent on a particular …

A Preliminary Study Of The Distribution Of Fleas In Utah Known To Be Capable And Potential Vectors Of Plague, Dorald M. Allred

Theses and Dissertations

Plague outbreaks in the past have been disastrous where domestic rats and their fleas of certain species were common. Plague has been known to occur in most parts of the world (Robertson 1923), and has occurred as human epidemics for many centuries (Dubos 1948).


Some Economic Aspects Of The Fluid Milk Industry Of Nebraska, Kenneth E. Anderson Jun 1951

Some Economic Aspects Of The Fluid Milk Industry Of Nebraska, Kenneth E. Anderson

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Most citizens of Nebraska, especially the dairy farmers who produced milk for city consumption, are currently concerned with the problem of marketing fluid milk.In Nebraska and all over the United States, sales of wholesale milk farmers have been increasing for the past 15 years, while cream sales to creameries have been decreasing.

Production of milk in Nebraska is greatest in the eastern part of the state.Likewise, consumption is concentrated in Eastern Nebraska. This is most likely due to Eastern Nebraska’s highly concentrated population as well as the most favorable farm conditions for dairy cows.

Most of the bottled milk in …


The In Vitro Determination Of Human Blood Oxygen Saturation In The Presence Of High Concentrations Of Carbon Dioxide, Elizabeth D. Armstrong May 1951

The In Vitro Determination Of Human Blood Oxygen Saturation In The Presence Of High Concentrations Of Carbon Dioxide, Elizabeth D. Armstrong

Biology ETDs

Mayow’s work in 1673 is cited by Landois (1905) as the first demonstration of the liberation of gases from blood in a vacuum. In 1863 Meyer, Ludwig, and Pfleuger established that the oxygen leaving the lung was transported in a combined form with hemoglobin and that the oxygen was released into the tissues accompanied by a change in color of the blood.


The Sweet Clover Weevil In South Dakota And Recommendations For Its Control, H.C. Severin May 1951

The Sweet Clover Weevil In South Dakota And Recommendations For Its Control, H.C. Severin

Agricultural Experiment Station Entomology Pamphlets (1940-1952)

The sweet clover weevil, bitona cylindricollis Fahr. is one of the principal insect pests attacking sweet clover in South Dakota. While the pest works on sweet clover principally, it has also been found feeding on other clovers and on alfalfa, although only in small numbers. The sweet clover weevil is a European insect which was first reported to have been taken on this continent near Montreal, Canada, in 1924. In 1941 it was found in South Dakota in small numbers but at the present time it occurs abundantly over the entire state.


Recommendations For The Control Of The Most Important Insect Pests Of Potatoes In South Dakota, H.C. Severin May 1951

Recommendations For The Control Of The Most Important Insect Pests Of Potatoes In South Dakota, H.C. Severin

Agricultural Experiment Station Entomology Pamphlets (1940-1952)

The important insect pests attacking potatoes in South Dakota must be controlled if a good or even a fair yield of potatoes is to be harvested. Many different species of insects attack growing potato plants in the state, but the insects of major importance do not form a long list. It is not necessary for the grower to be able to recognize the minor potato insects, but it is a distinct advantage to be able to recognize the major species. Further, it would be profitable if the potato grower would familiarize himself with the life cycle and seasonal h}story of …

A Special Respiratory Mechanism In The Adrenal Gland Of Cattle, Martin Roeder

Biology ETDs

The first definite evidence for the existence of an enzyme which catalyzes the biological oxidation of phenols was presented was presented in 1896 by Bourquelot and Bertrand. By 1902 the latter had characterized the enzyme as acting directly on the amino acid tyrosine, and had demonstrated its action against other substances, including p-hydroxyphenylethylamine, p-cresol, and phenol.

The Life Cycle Of The Ostracod Cypricercus Reticulatus (Zaddach, 1844) Sars, 1928, Louise E. Goeke May 1951

The Life Cycle Of The Ostracod Cypricercus Reticulatus (Zaddach, 1844) Sars, 1928, Louise E. Goeke

Biology ETDs

The purpose of the present study is to describe the stages in the life-cycle of the fresh-water ostracod, Cypricercus reticulatus (Zaddach,1844) Sars, 1928 of the family Cypridae. This particular species was chosen primarily because of availability. The selection of this species was fortunate since C. reticulatus was found to be easily adapted to laboratory conditions. In addition, the form was a fortunate selection because the period of time required for reproduction is relatively brief and the species reproduces parthenogenetically, thus eliminating difficulties incident to impregnation of the females.

Stratigraphy Of The Woodbine And Eagle Ford, Waco Area, Texas, W. S. Adkins, Frank E. Lozo May 1951

Stratigraphy Of The Woodbine And Eagle Ford, Waco Area, Texas, W. S. Adkins, Frank E. Lozo

Fondren Science Series

In the last twenty years, very little detailed stratigraphy of this area has been published. Meanwhile there have been significant advances in this field: the aims of modern stratigraphic research have been somewhat clarified; much new information pertinent to the stratigraphy of this area has been accumulated from the study of other areas; and a considerable amount of detailed information on the surface and subsurface geology of this area has come to light as a result of detailed outcrop work, extensive drilling of oil tests and water wells, and new techniques of bore-hole logging. The scope of this work is …

The Grand Prairies Of Texas, Frank Bryan May 1951

The Grand Prairies Of Texas, Frank Bryan

Fondren Science Series

Welcome to the Grand Prairies of Central Texas. They were first so called by that grand old man of early Texas geology, Dr. Robert T. Hill. These prairies offer no spectacular, breath-taking landmarks to the viewing eye. They offer only a broad vista of rolling prairie hills. Yet this can be a thrilling vista, once you know the details of its history back into remote antiquity.


History Of Discovery And Development Of Woodbine Oil Fields In East Texas, C. I. Alexander May 1951

History Of Discovery And Development Of Woodbine Oil Fields In East Texas, C. I. Alexander

Fondren Science Series

The purpose of this paper is to present a brief historical summary of the discovery and development of the Woodbine oil fields of East Texas. A simple listing, or tabulation of the Woodbine oil fields, with discovery dates, would be dry reading, indeed, so I will try to review the history of this important oil producing formation and area as a story - a story of lines or trends of geological thought, of lease plays and exploratory operations resulting from these lines or trends of thought; and of the changes in geological thought resulting from some of the more important …

Comparative Status Of The Woodbine In Oil Production, G. J. Loetterle May 1951

Comparative Status Of The Woodbine In Oil Production, G. J. Loetterle

Fondren Science Series

While the relative importance of the Woodbine as an oil producing formation is well known in a general way, the purpose of this study is to bring that importance into more specific focus. It is hoped thereby to emphasize even more clearly the economic significance of the present field excursion, and to highlight the tremendous role of Woodbine production as a natural resource.


Woodbine Sandstone Dikes Of Northern Mclennan County, Texas, John Napier Monroe May 1951

Woodbine Sandstone Dikes Of Northern Mclennan County, Texas, John Napier Monroe

Fondren Science Series

A review of the literature indicates that clastic dikes, generally considered curiosities, are common features of many marine shales and marls. Excepting the Eagle Ford shale, dikes have been found by the writer in all of the Upper Cretaceous groups of northeastern Texas. Studies of twenty-one Woodbine dikes in McLennan County indicate that most of these were formed by the deposition of marine sediment in tension cracks opened along the sea floor during the time that an upper sand member of the Pepper formation was deposited. This hypothesis is based on the presence in the dikes of bedding, as indicated …


The South Bosque Field, Mclennan County, Texas, J. C. Price May 1951

The South Bosque Field, Mclennan County, Texas, J. C. Price

Fondren Science Series

The South Bosque Field is located in McLennan County, Texas about eight miles southwest of the city of Waco. At one time, the field covered an area approximately one-half mile wide and three miles long, extending from the vicinity of the town of South Bosque to Hog Creek. There are very few good records of the wells available at this time, so, unfortunately, much of the information relative to this field is conflicting and unreliable.


Stratigraphic Notes On The Maness (Comanche Cretaceous) Shale, Frank E. Lozo May 1951

Stratigraphic Notes On The Maness (Comanche Cretaceous) Shale, Frank E. Lozo

Fondren Science Series

In 1941, the writer was advised of the opinions of T. L. Bailey, F. G. Evans, W. S. Adkins, and other geologists of the Shell Oil Company on the stratigraphic position of the uppermost Comanche shale unit recognized in the subsurface of eastern Texas. Their studies pointed to the conclusion that this unit, now known as the Maness shale, is (1) stratigraphically younger than the subsurface Del Rio (or Grayson) shale with which it usually had been correlated, and (2) conformably overlies the Buda limestone, at this date generally misidentified as the Georgetown limestone. An investigation of the controversial sequence …

Geology Of Belton Reservoir Area, Leon River, Bell County, Texas, Jack Colligan

Fondren Science Series

Location of project. Belton Reservoir will be formed by construction of an earthen dam on the Leon River at about river mile 16.7, approximately 3 miles north of Belton. The reservoir will occupy a northern portion of Bell County and a southeastern portion of Coryell County. Sites investigated. An extensive subsurface investigation was made of the project document site at river mile 15.5. Subsurface explorations disclosed adverse leakage and unfavorable geologic conditions, and as a result the site was abandoned. A dam site at about river mile 16.7 was investigated and found to be geologically satisfactory for development of the …
