Origin Of Some Recent Tractional Sedimentary Structures In The Rio Puerco Near Bernardo, Socorro County, New Mexico, Lawrence H. Wagner

Earth and Planetary Sciences ETDs

The Rio Puerco, in the area of study, occupies a valley eroded in the Santa Fe formation. The silty alluvium is incised by the present channel of the Rio Puerco to a depth of 10 to 25 feet. The depth of the alluvial fill in the area is not known. The channel is 50 to 300 feet wide with braod meanders interspersed with straight reaches. The Rio Puerco is ephemeral in the lower reaches with flow produced by local rains on the watershed.


Petrography Of The Olalla Stock, Okanagan Mountains, British Columbia, James Anton Sturdevant May 1963

Petrography Of The Olalla Stock, Okanagan Mountains, British Columbia, James Anton Sturdevant

Earth and Planetary Sciences ETDs

The Olalla stock is located in the Okanagan Mountains of south-central British Columbia, about 20 miles north of the international boundary. It occupies approximately 6 square miles and consists of late Mesozoic mafic and ultramafic rocks and subordinate alkalic rocks, which have intruded previously folded and metamorphosed sediments of the Triassic (?) Shoemaker Foundation.

The rocks of the stock may be broadly grouped into two major categories: (1) those formed from the differentiation of a crystallizing magma that probably entered during the Nevadan orogeny, and (2) those formed by metasomatic replacement of pyroxenite. The rocks of the first category are, …


Convergence Functions And Their Related Topologies, Darrell C. Kent May 1963

Convergence Functions And Their Related Topologies, Darrell C. Kent

Mathematics & Statistics ETDs

A convergence function is a correspondence between the filters on a given set S and the subsets of S which specifies which filters converge to which points of S. This concept is defined to include types of convergence which are more general than that defined by specifying a topology on S. Thus a convergence function may be regarded as a generalization of a topology.


The Geology Of The South Mountain Area, Bernalillo, Sandoval, And Santa Fe Counties, New Mexico, Tommy B. Thompson May 1963

The Geology Of The South Mountain Area, Bernalillo, Sandoval, And Santa Fe Counties, New Mexico, Tommy B. Thompson

Earth and Planetary Sciences ETDs

South Mountain is approximately 30 miles northeast of Albuquerque in the southern end of the San Pedro-Ortiz porphyry belt. It is a Tertiary monzonite laccolith that intrudes the Permian Abo and Yeso Formations and, in places, the Permian Glori eta Sandstone. The base of the lac­eolith lies on the Abo except in the southeastern part where it overlies the Mes eta Blanca Member of the Yeso. The incompetence of the Yeso appears to nave allowed the monzonitic magma to spread laterally throughout the stratigraphic interval up to the Glorieta Sandstone which was more resistant and broken only locally by the …

Self-Diffusion In Single-Crystal Tungsten And Diffusion Of Rhenium Tracer In Single-Crystal Tungsten, Robert L. Andelin May 1963

Self-Diffusion In Single-Crystal Tungsten And Diffusion Of Rhenium Tracer In Single-Crystal Tungsten, Robert L. Andelin

Chemistry and Chemical Biology ETDs

Self-diffusion in single-crystal tungsten and diffusion of rhenium tracer in single-crystal tungsten have been measured over the temperature range 2660°C to 3230°C by the direct sectioning technique. The initial radioactive layer of tungsten and rhenium tracers was produced on the diffusion samples by bombardment with 9.0-MeV deutrons. It was shown that the initial radioactive layer satisfactorily approximated the boundary-condition requirements of the one-dimensional diffusion equation. The tracers observed in determining the diffusion coefficients were W185, Re183, and Re184. Diffusion heating of the samples in high vacuum was accomplished by an induction-heating arrangement which included …

The Development Of Irrigation In Nebraska, 1854–1910: A Descriptive Survey, Martin Evald Carlson May 1963

The Development Of Irrigation In Nebraska, 1854–1910: A Descriptive Survey, Martin Evald Carlson

Department of History: Dissertations, Theses, and Student Research

Preface (excerpted)

The primary purpose of this study is tto trace the development of irrigation in Nebraska from the organization of the state as a territory in 1854 through the rest of the nineteenth century. This period covers the first four stages through which irrigation progressed: individualistic, corporate, district, and state. A brief discussion of the North Platte Project is included, however, in order to carry the story into the fifth and final stage--the development of irrigation with Federal aid, as provided for in the Reclamation Act of 1902.

The emphasis of this work is on the irrigation movement and …


The Lower Devonian Water Canyon Formation Of Northeastern Utah, Michael E. Taylor May 1963

The Lower Devonian Water Canyon Formation Of Northeastern Utah, Michael E. Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1948 Williams subdivided the Jefferson Formation of northeastern Utah into two formations. The upper formation was referred to as the Late Devonian Jefferson Formation and the lower formation the Early Devonian Water Canyon Formation (Williams, 1948, p. 1138). Since that time detailed study of the Water Canyon Formation has not been made. It is the purpose of this investigation to describe in detail the lithology and paleontology of the formation and their implication as to the environment of deposition of Early Devonian time in northeastern Utah.


Topological Groups, Nicolas Anthony Thireos May 1963

Topological Groups, Nicolas Anthony Thireos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A topological group is an abstract group which is also a topological space and in which the group operation are continuous. In group theory the algebraic binary operation of passage to a limit is studied in a similar manner. The two fundamental mathematical concepts of binary operation and passage to a limit are united and interrelated in the concept of topological group.

The concept of topological groups arose from the study of continuous transformations. However, topological groups can be studied quite independently from continuous transformations and the latter can be presented as applications of topological groups. The first person to …


Pressure Dependence Of Soil Water Matric Potential, Bozorg Bahrani May 1963

Pressure Dependence Of Soil Water Matric Potential, Bozorg Bahrani

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The partial specific Gibbs1 free energy or the chemical potential has been shown to be the most desirable thermodynamic function for describing soil-water systems. The absolute value of the chemical potential of soil water cannot be determined. If pure water at standard temperature and pressure is taken as the reference, the difference between the chemical potential of soil water and that of the reference can be measured and is called "soil water potential," which has the dimension of energy per unit mass.

The barometric pressure at the sea level has been accepted as the standard reference pressure. Thus, any …


Nuclear Quadrupole Resonance Of Chlorine35 In Ammonium Chlorate And Ammonium Perchlorate, James Derwin King May 1963

Nuclear Quadrupole Resonance Of Chlorine35 In Ammonium Chlorate And Ammonium Perchlorate, James Derwin King

Theses

Nuclei which have a spin number, I, greater than 1/2 usually have an electric quadruple moment as well as a magnetic moment. The electric quadrupole moment describes the deviation from spherical symmetry of the positive charge over the nucleus. Interaction of this electric quadruple moment of the nucleus with an inhomogeneous (axially symmetric) electric field existing in molecules and crystals due to the surrounding charge cloud causes radio frequency resonances to exist. The resonant frequency is dependent on the nuclear quadruple moment as well as the shape and magnitude of the electric field existing at the nucleus due to the …

Distress In Children Going To X-Ray, Ina Madge Longway May 1963

Distress In Children Going To X-Ray, Ina Madge Longway

Loma Linda University Electronic Theses, Dissertations & Projects

It is commonly recognized that hospitalized children need psychological support and preparation for painful procedures. It is probable that little thought is given by hospital personnel to a similar preparation of the child for non-painful procedures. This study attempted to evaluate the distress incurred by children subjected to non-painful hospital procedures with little or no preparation. The procedure of x-ray was selected as being common and typical. The method used was the descriptive survey. The tools used were the taking of a series of six blood pressure readings per child, the administration of two forms of a short psychological test …
