Factors That Influenced Homesteading And Land Abandonment In San Juan County, Utah, Melvin J. Frost

Theses and Dissertations

Homesteading in San Juan County, Utah is for the most part, located on Sage Plain at elevations between 6,000 to 7,200 feet. Sage Plain is an undulating surface deeply dissected with canyons. The soil is relatively shallow and the predominant vegetation is pinyon, juniper, sage brush and blue-stem grass.

The 52 year mean precipitation is 15.47 inches. Since the beginning of weather records there has been a noticeable decrease in the annual precipitation. There is generally sufficient moisture to mature winter wheat. Pinto beans are also grown in the more favorable locations.

Principle factors that have influenced homesteading and land …

Studies In The Mulga Pastoral Zone. 1. The Grazing Of Wandarrie Grass Associations, D G. Wilcox

Journal of the Department of Agriculture, Western Australia, Series 4

THE establishment of the Wiluna office of the North-West Branch marked the commencement of a series of investigations into the pastures of the mulga zone.

Unlike the agricultural areas where a fund of knowledge exists on the growth habits of the pastures, the pastures of this area were completely unknown.

The preliminary investigations had to be aimed at forming an understanding of the reactions of the various plants to rain, to temperature and seasonal conditions and to grazing in an area of extremely low rainfall reliability.

Tetracycline-7-Boronic Acid, William Denham Rhoads

University of the Pacific Theses and Dissertations

The objective of this study is the preparation of a tetracycline-boron-10 derivative which is stable under biological conditions. The boron-10 should then provide a concentration of material capable of accepting thermal neutrons, thus producing localized high-energy alpha radiation. The fact that the tetracyclines are not retained by normal tissue should remove the danger of destruction of this tissue.

Stratigraphy Of The Winnipeg And Deadwood Formations In North Dakota, Clarence G. Carlson

Theses and Dissertations

The Deadwood formation includes all of the pre-Winnipeg sedimentary rocks of North Dakota which range in thickness from an erosional edge in the subsurface of northeastern North Dakota to at least 1,000 feet in northwestern North Dakota. It is composed of sandstone, shale, and carbonate of Late Cambrian to Early Crdovician age. Facies relationships are not entirely clear, but sedimentation appears to have been continuous from Late Cambrian to Early Crdovician in the Williston Basin. Conodonts from the upper part of the Deadwood formation in northwestern North Dakota are brownish-black, mostly simple cone types and suggest an Early Drdovician age …

The Surficial Geology Of North-Central Kidder County, North Dakota, Wallace E. Bakken

Theses and Dissertations

Kidder County is situated in central North Dakota within the glaciated Missouri Plateau. Rocks underlying the drift range from Cretaceous (Pierre formation) through Palocene (Tongue River formation) in age. The Pierre and Fox Hills formations constitute the majority of the pre-Pleistocene surface. Ice-shove deformation, apparently during Cary time, tilted blocks of Fox Hills in the Sibley Buttes into northeastward-dipping positions.

Cary and Mankato subages of Wisconsin age are represented at the surface. Ages are difficult to assign to drift sheets on the basis of lithology or degree of weathering of included tills; but by correlation from South Dakota and crosscutting …

Pleistocene Geology Of Northern Kidder County, North Dakota, James Chmelik

Theses and Dissertations

The topography of northern Kidder County is due almost entirely to glacial deposition. This are is covered with glacial drift up to a thickness of at least 269 feet which was deposited during Wisconsin ice advances. Seventy-five percent of the area has stagnation moraine which typically exhibits knob-and-kettle topography, has high local relief with no linear trends, and which was deposited after the ice became stagnant. Many kames and eskers were formed contemporaneously with stagnation moraine. The names, Lake Williams and Woodhouse Lake loops, and proposed for and moraines deposited by Cary and Mankato ice advances, respectively. The Lake Williams …

A Movement West, Robert Katz

Robert Katz Publications

I did not discover that I had any interest in teaching or in academic life until late in my twenties, and then only through a sequence of unrelated circumstances.
I was born in 1917. My parents were Russian-Jewish immigrants who came to New York City at about the turn of the century.
At sixteen I enrolled in Brooklyn College, a recently organized, tuition-free, municipal college, then housed in rented office buildings in downtown Brooklyn. It took an hour to get to or from school on the subway. I managed to choose this inconvenient location because this school seemed most likely …

Cyclic Sedimentation Of The Upper Fayetteville Formation, Faramarz Frouzan

Masters Theses

"In the past decade considerable interest has developed in the geology of the Boston Mountain area of northern Arkansas. This has been due to exploration for oil and gas in-the area and the related desire to know more about the structure and stratigraphy of the region. Principal work has been done by the University of Arkansas, the United States Geological Survey, and oil companies. This study involves only one of the formations making up the geologic column in the Boston Mountains, the Upper Mississippian (Chesterian Series) Fayetteville Formation.

Portions of the upper part of the Fayetteville Formation of northwestern Arkansas …

Comparative Petrographic, Petrochemical And Spectrographic Analyses Of The Precambrian Granitic Rocks Of Southeastern Missouri, Eva B. Kisvarsanyi

Masters Theses

"Petrographic, petrochemical and spectrographic studies were completed on selected Precambrian granitic rock samples from Southeastern Missouri. This investigation contributes to a more detailed knowledge of the Precambrian granitic rocks of this part of the state.

Petrographic analysis of forty-four thin sections of granitic rocks from the St. Francois Mountains area revealed six different granite types. These have been named the Fredericktown, Knoblick, Doerun, Graniteville, Klondike and Silvermine granites. These rocks form a large part of a composite batholith. More than one period of granitic intrusion is represented, but differentiation also contributed to the formation of this diversity of the rocks. …

The Dielectric Strength Of Some Anti-Corrosive Paints, John Harvey Gustafson

Masters Theses

"Metals undergo chemical reaction with nonmetallic elements of their surroundings to produce compounds which are either oxides or salts. These corrosion products, as they are called, may accelerate, impede, or have no influence on the course of further corrosion. It is unfortunate that iron, the metal of greatest use to man, receives very little protection from its corrosion products. There are no easy or inexpensive means of prevention of this corrosion and at best the reactions can only be controlled. One method of control is the use of anti-corrosive paints. Their protection is produced by placing an inert, continuous, and …

Water Resources Development -- An Analysis Of Economic Justification Practices Of The Corps Of Engineers, Kerwood W. Barrand

Masters Theses

"Presented herein is a brief analysis of the economic justification practices of the Corps of Engineers as commonly implemented in proposals concerning water resources projects. Where applicable, recommended methods are compared to similar methods advocated for, and accepted by, private engineering firms in similar situations.

The major problem exists in the lack of a profit motive in programs undertaken with the use of public funds. However, a profit can be said to have been realized in public works programs if the total benefits of the programs to all the people exceed the costs of these programs and, further, if the …

Mississippian Bioherms Of Southwestern Missouri And Northwestern Arkansas, Arthur R. Troell Jr.

Masters Theses

"Lenticular bodies of massive limestone, flanked by thin crinoidal beds, crop out in southwestern Missouri and northwestern Arkansas. They are within the St. Joe limestone of the Lower Mississippian.

Strata underlying these bodies typically are down-warped, those on the flanks lapping against, finally passing completely over the limestone core. Dips away from the “reef” are commonly around 5 degrees, but reach as much as 30 degrees. Conglomeratic detritus, originating from the core, occurs in flanking beds at their contact with it.

Thin sections of these masses show no more than 15 per cent of the limestone to consist of fossil …

Glacial Geology Of South-Central Kidder County, North Dakota, Barrett J. Williams

Theses and Dissertations

South-central Kidder County is covered with deposits of drift brought by ice sheets which invaded the areas from the northeast and east. Bedrock of Cretaceous age underlies the drift mantle. The drift on the surface in Kidder County represents the Cary and Mankato substages of the Wisconsin Stage of Pleistocene series.

Three types of moraines, ground, stagnation, and end moraine, are present in the area. Five late Wisconsin and moraines are distinguished and named in this portion of Kidder County. These are, from west to east and oldest to youngest, the Long Lake loop and Sibley Buttes loop of Cary …

3-Amino-2,5-Dihydroxy-5-Sulfo-Benzoic Acid, Hideo Tomomatsu

University of the Pacific Theses and Dissertations

It seems possible that efforts to discover essential chemical differences which might exist between normal and malignant cells will eventually reveal the secret of cancer and thereby lead to new approaches to safer and more selective chemotherapy.

One objective of this study is to find that part of this molecule that causes it to concentrate in the tumor and thence make a smaller size compound which has similar concentration characteristics to tumor as tetracycline. For this purpose, an attempt was made in this study to synthesize the right side ring of Chlorotetracycline, the structure of which is shown below. [see …
