Engineering Properties, And Slope Stability And Settlement Analysis Related To Phosphate Mine Spoil Dumps In Southeastern Idaho, Richard Ellsworth Riker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The engineering properties of waste spoil from phosphate mines in Southeastern Idaho were determined through field and laboratory testing. The testing included compaction tests, grain size analysis, powder x-ray defraction tests, permeability tests, compression tests, triaxial and direct shear strength tests, and nutrient analyses. Based on these tests, the slope stability and settlement characteristics of phosphate spoil dumps were investigated.

The study showed that the foundation is an important component of the stability of a spoil dump. Hypothetical examples were used to illustrate possible modes of foundation failures. Such failures might occur when weak foundation soils exist or when there …

A Mathematical Model Of The Dispersion Of A Concentrated Substance For Use In The Great Salt Lake's South Arm, Anthony O. Rughellis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ability to predict the dispersion of substances in the Great Salt Lake is a requisite towards making responsible management decisions relating to uses of the lake. The lake is a complex terminal body of water and will require a fairly sophisticated mathematical model to properly simulate the dispersion process in the lake. This finite element convection-dispersion model is a first step towards developing a comprehensive model.

The model provides a finite element solution to the two-dimensional convection-dispersion equation and is capable of simulating steady or unsteady-state situations. It utilizes a known velocity field, dispersion coefficients, an introduced substance concentration, …

A History Of John W. Young's Utah Railroads, 1884-1894, Marlowe C. Adkins Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This is the story of three narrow gauge, short line railroads. Had fate been kinder, they might have become the hub of a major mountain west rail network. But this thesis will deal with facts, not possibilities, as it investigates the justification, construction, financing, and politics that surrounded these railroads and their location.

The locale was in and near Salt Lake City, Territory of Utah, during the decade between 1883-1894. Both location and time period have significance, for anti-Mormon feelings, within and without the the Territory, were very strong.

The visible cause of the anti-Mormon movement was polygamy.¹ For, …

An Analysis Of Land Use Transfers, Agricultural Production, And Rural Zoning Requirements In Selected Utah Counties, 1974 Through 1976, Eldon James White

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Increased incomes, better transportation, and the desirability of country living all create the demand for land in the agricultural-urban fringe areas to increase. High land values, low returns on investment, and residential encroachment place farmers in a situation where continued agricultural production is difficult. As ownership transfer occurs, the use of land is often changed. This study is directed at measuring the effects of ownership transfers in rural areas of rapidly urbanizing counties on the local agricultural industries, and the effect of zoning requirements on these transfers.

The study sample consisted of land buyers recorded at the Utah State Tax …

Reduced Recruitment In Utah Mule Deer Relative To Winter Condition, Phillip J. Zwank

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reduced recruitment rates in Utah mule deer (Odocoilus hemionus) showed that significant losses in production were accruing during pregnancy, the neonatal period or during the first few months after birth. The primary objectives of the study were to determine the time, extent and possible causes of these losses.

Corpora luteal and fetal rates were estimated by examining the reproductive tracts of 125 carcasses collected on selected herd units in Utah and by observing the reproductive tracts of 136 female deer captured in Spanish Fork Canyon. A laparotomy was performed on each captured female to allow visual examination of the reproductive …

Nonresident Enrollment Demand At Utah State University, William G. Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The determination of the level of student registration fees at colleges and universities in many cases appears to be made without adequate consideration given to probable enrollment responses and to the associated implications for tuition revenues. This study was aimed at reducing this information gap at Utah State University and focused specifically on past sensitivities of students from neighboring western states to changes in the nonresident charges at USU. The analytical framework employed in this investigation specified a causal link between the proportion of the college-attending populations from these states choosing to enroll at USU and comparative tuition levels.

The Effect Of Architectural Variation In Habitat On A Spider Community: An Experimental Field Study -- With Special Reference To Resource Partitioning, James Vincent Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spider community acceptance of, and segregation by, architectural configuration was investigated for the spiders of Green Canyon in northern Utah. Modular habitat units consisting of 30.48 centimeter (1 foot) cubes of chicken wire supporting internal strands of macrame jute tied in different orthogonal configurations were used. Configurations including all three axes were tested at two strand densities.

The primary null hypothesis tested, that spider species use structures independent of architecture, was rejected in favor of the alternate hypothesis that spider species differentially use structures dependent upon architecture. Of the eight most abundant species, two showed preferences for horizontal substrata and …

Topological Properties Of C(X, Y), Chris Alan Schwendiman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper is to examine the important topological properties of the function spaces BC(X,Y) and C(X,Y). Emphasis is given to the relationship between the metrizability of X and the separability of these function spaces. The paper is divided into three major parts: the preliminary definitions and theorems; the relationship between the topological properties of X and BC (X ,Y), for compact X; and the extension of the results of Part II for X not compact and for the case when we have C(X, Y).

Interpretation Of Principal Components, Marwan A. Dabdoub

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The principal component analysis can be carried out two ways. First the R-mode:

R = K'K

and the second is the Q-mode:

Q = K K'

where K is a data matrix centered by column or by row. The most commonly used method is the R-mode.

It has been suggested that principal components computed from either the R-mode or the Q-mode may have the same interpretation. If this is true, then interpretation of the principal components could be put on a much more intuitive level in many applications. This will occur whenever one type of principal component …

Production And Intake Responses Of Dairy Cows Fed Four Levels Of Malic Acid, Juan Carlos Martinez Alferez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Malic acid allotment for each treatment consisted of 1) 15.4, 2) 11.6, 3) 7.7, and 4) 0 grams of malic acid fed per kilogram of concentrate. Concentrate was fed according to production at a rate of one kilogram per two kilograms of milk in excess of 9.1 kilograms of milk per cow daily. Alfalfa hay was fed free choice and corn silage at a rate of 11.4 …

A Unified Radiometric Assay System For The Gaba-Glutamate Regulating Enzymes, Robert C. Dinwoodie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper was to develop a single assay system for the enzymes which regulate GABA and glutamate concentrations in brain and nerve tissue. Since all the enzymes produce L-glutamate, their activities were measured by coupling them to L-glutamate decarboxylase. Enzymatic activity was determined by measuring the release of co2 from radioactive substrates. The glutamate decarboxylase was obtained from a commercial acetone powder by simplifying existing procedures. The glutamate decarboxylase produced was of sufficient purity to be used in the coupled assays, which were checked with commercial preparations of each enzyme, where available, and with crude brain homogenates. …

Studies Toward The Synthesis Of A- And B- Mercapto Alanine Derivatives, And Of A,B- And B, B- Dimercapto Alanine Derivatives, Aldean James Kolar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A convenient, economical, large scale synthesis of N-acetyldehydro-alanine (a-acetamidoacrylic acid) and its methyl ester was developed via a sequence of N-chlorination-dehydrochlorination. The method was extended to the synthesis of the corresponding N-benzoyl, N-phenylacetyl and N-benzyloxycarbonyl derivatives.

The conversion of a-methoxy-N-acetyl alanine derivatives to the corresponding a-mercapto alanine derivatives, using zinc chloride and an appropriate mercaptan, was investigated. Methyl a-methoxy-N-acetyl-D, L-alaninate was successfully converted to the a-acetylthio derivative, in 24% yield; however, a 90% yield could be obtained by treatment of the dehydroalanine derivative with hydrogen chloride gas in neat thiolacetic acid.

A facile conversion of the a-acetylthio derivative to the …

The Combined Effects Of Air Temperature, Wind, And Radiation On The Resting Metabolism Of Avian Raptors, Steven R. Hayes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

American kestrels, Falco sparverius; red-tailed hawks, Buteo jamaicensis; and golden eagles, Aguila chrysaetos, were perched in a wind tunnel and subjected to various combinations of air temperature, wind, and radiation. Oxygen consumption was measured under the various combinations of environmental variables, and multiple regression equations were developed to predict resting metabolism as a function of body mass, air temperature, wind speed, and radiation load. Heat transfer analysis of the bird-thermal environment relationship was conducted to produce a biophysical model describing resting metabolism as a function of feather thermal conductance.

Because of differences in surface area to mass …

Comparison Of Microbial Activity In Desert Soils Of The Western United States, Patricia Ann Trujillo Y Fulgham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soils from four regional deserts, Great Basin, Sonoran, Chihuahuan, and Mojave, were collected at times throughout the year which would best exhibit microbial response to moisture or vegetation. The soils were analyzed for several chemical and physical properties. Biological and biochemical characteristics, namely respiration, dehydrogenase activity, adenosine triphosphate concentration, proteolytic activity, nitrification potential, and microbial numbers, were measured.

The soils exhibited fluctuations in microbial activity as measured by respiration, dehydrogenase activity, adenosine triphosphate concentration, proteolytic activity, and nitrification potential during different moisture seasons.

Increase in soil moisture as modified by precipitation did not cause a significant difference in respiration or …

Competition And Spacing Patterns Of Shrubs In The Mojave And Sonoran Deserts, Donald Lundahl Phillips

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spacing patterns of shrubs were studied at a series of sites in the Mojave and Sonoran Deserts. There were significant numbers of occurrences of both aggregation and regularity in dispersion of individuals. These may be due to vegetative reproduction or environmental heterogeneity, and competition between plants, respectively. Different size classes of shrubs tended to follow the trend of aggregated → random → regular with increasing size. This suggests the increasing importance of competition as the plants grow. Further evidence of competition between plants was provided by the correlations of plant size with the distance to their neighbors. Root systems were …

Analysis Of Ecosystem Models, Walter Dewey Valentine

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent attempts to apply frequency response analysis to compartmental models of ecosystems are flawed by the failure to define terms in an unambiguous and ecologically meaningful way, and by the failure to distinguish between information feedback and closed material loops. Analysis of the sensitivity of linear models to changes in the A matrix has shortcomings too: elements of the A matrix are often derived from more fundamental parameters and thus do not have a direct relationship to the parent model; only sensitivities to the fundamental parameters will be unconfounded and readily interpretable. A more serious problem with these techniques is …

Primary Prevention Of Child Abuse And Neglect: Identification Of High Risk Adolescents Prior To Parenthood, Stephen John Bavolek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of the study was to develop a valid and reliable instrument designed to assess the parenting and child rearing attitudes of adolescents, Responses to the instrument would allow for the identification of "high risk" adolescents, i.e., those adolescents whose attitudes towards parenting and child rearing indicated a high potential for child abuse.

A review of the literature identified the following four parenting constructs most commonly associated with abusive parents: Construct A: Inappropriate parental expectations of the child; Construct B: Inability of the parent to be empathically aware of the child's needs; Construct C: Strong parental belief in the …

Life Span Learning And Utah State University, J. Clark Ballard

Faculty Honor Lectures

The recent Kellogg Life Span Learning Grant has focused national attention on Utah State University as a model for life span learning. Historically, Extension and at least the rudiments of life span learning, have been a part of Utah State University since its founding in 1888. In 1896, the State passed the Cazier Bill which appropriated $1,500 to conduct a Farmers Institute in each county at least once a year (Ricks 1938). Such activities were mostly conducted on an informal basis until 1911 when Luther M. Winsor, Instructor of Irrigation, was employed as county agent in the Uintah Basin. This …
