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

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

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

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

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

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

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 …

Losses of soil nitrogen that cannot be attributed to leaching or crop removal have been observed in many field experiments. Several mechanisms have been proposed to account for these losses.

Differentiation Between The Ph Effect And The Bicarbonate Ion Effect In Causing Lime-Induced Chlorosis, Hyrum Del Var Petersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lime-induced chlorosis has been recognized for many years as a problem where plants are grown on calcareous soils. There are many factors associated with and influencing this form of iron chlorosis and because of this it has been very difficult to determine the relationship between the factors and chlorosis.

Salt Effect On Water Requirements Of Plants, Abdel-Wahhab M. H. Sallam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water requirement was defined by Briggs and Shantz in 1911 as the ratio of the weight of water absorbed by a plant during its growth to the weight of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter formed during the whole or any part of the life cycle of the plant. Miller (1938) and Kramer (1959) postulated that …

A Field Study Of Miscible Displacement In Saturated Soils, Lloyd Dowley Mcfadden Sadler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extensive research has been carried out in both field and laboratory to explain water and solute movement under both saturated and unsaturated conditions. The importance of such work is obvious, since any attempt at exploring land reclamation by leaching or nutrient movement in plant feeding (to name only two) is subject to interpretations and theories of moisture flow.

Water flow through soil during reclamation by leaching can be termed miscible displacement since soil water and leaching water do not have a distinct fluid-fluid interface and will physically mix. It is probable that miscible displacement investigations can contribute to an understanding …

Theory Of The Effect Of Temperature On The Electron Diffraction Patterns Of Diatomic Molecules, Russell A. Bonham, Jerry Peacher

Physics Faculty Research & Creative Works

The effect of temperature on the electron diffraction pattern of a diatomic molecule is considered from the standpoint of the simple kinematic scattering theory utilizing a quartic vibrational potential. The potential is obtained by an expansion of ħ²J( J+1)/2μr²+D exp[-2a(r-r_e)]-2D exp[-a(r-r_e)] about its minimum value r₀. The second-order wavefunction for the nth vibrational and 7th rotational state of the system has been obtained, and expressions for the electron diffraction quantities r_g, l_e ², and M (s) have been computed. General results for the quantity M (s) …

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 …

(1) for all a,b ∑ B (that is, for all a,b elements of B) a + b = b + a and a b = b a, (the commutative laws),

(2) for all a,b,c ∑ B, a + b c =(a + b) (a + b) …

Investigation Of The Properties Of The Iterations Of A Homeomorphism On A Metric Space, Murray B. Peterson, Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Considerable study has been made concerning the properties of the iterations of a homeomorphism on a metric space. Much of this material is scattered throughout the literature and understood solely by a specialist. The main object of this paper is to put into readable form proofs of theorems found in G.T. Whyburn's "Analytic Topology" pertaining to this topic in topology. Properties of the decomposition space of point-orbits induced by the iterations of a homeomorphism will compose a major part of the study. Some theorems will be established through series of lemmas required to fill in much of the detail lacking …

An Investigation Of The Properties Of Join Geometry, Louis John Giegerich Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper presents a proof that the classical geometry as stated by Karol Borsuk [1] follows from the join geometry of Walter Prenowitz [2].

The approach taken is to assume the axioms of Prenowitz. Using these as the foundation, the theory of join geometry is then developed to include such ideas as 'convex set', 'linear set', the important concept of 'dimension', and finally the relation of 'betweenness'. The development is in the form of definitions with the important extensions given in the form of theorems.

With a firm foundation of theorems in the join geometry, the axioms of classical geometry …

Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson

Conservation and Survey Division: Faculty and Staff Publications

The purpose of this study is to describe and correlate rocks of Mississippian age within the state of Nebraska. Shales, generally classified as "Chattanooga" and commonly referred to as Devonian or Mississippian in the northern Mid-Continent, have been included in this study, although these shales are more generally believed to be Devonian and not Mississippian by most stratigraphers and paleontologists at the present time. Since rocks of Mississippian age are present only in the subsurface of Nebraska, the basic information for this report is derived from the microscopic study of cuttings and cores from test wells drilled within the state.
