Economic Impacts Of Irrigation Technologies In The Sevier River Basin, Theodore R. Frickel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The economic well-being of the semi-arid intermountain area requires efficient use of available water supplies. Agriculture, the major water-consuming industry, depends on irrigation water. The adoption of sprinkler systems that increase irrigation "efficiencies" and increase water available for irrigation upstream may interfere with the "tenure" of downstream water rights. The farmers would like to use the water saved to irrigate additional acreages or crop to provide greater profits.

The problem in letting farmers expand their irrigated acreage is that the individual farmer increases his profits through increased consumptive use. The consequent reduction in return flows reduces the water available to …

Habitat Use By Breeding Waterfowl Of Several Utah Marshes, Paul M. Suchanek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Habitat use by waterfowl (breeding pairs and broods) of several Utah marshes was studied during 1978 and 1979. A number of ponds found on 5 different marshes located near Great Salt Lake were studied. Perimeter, area, depth, and emergent vegetative type were measured on each pond. Waterfowl use of the ponds was determined using a fixed point observation system. Multiple regression was used to analyze the relationships between the measured habitat variables and waterfowl use.

Area of the pond was the variable most strongly related to both pair and brood use. Perimeter was highly correlated to area, but a calculated …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Synaptosomal membrane functions were monitored, after in vitro exposure to select environmental pollutants, in synaptosomal preparations originating from rat cerebral cortices. The uptake of NE and 5HT into the synaptosomes was monitored as was the K⁺-dependent phosphate activity of the membrane. CH₃HgCl, Hg(NO₃)₂, CdCl₂, diisopropylfluorophosphate (DFP), paraoxon, acrylamide and Kepone were the test chemicals whose effects were studied.

CH₃HgCl, Hg(NO₃)₂ and Kepone had the greatest inhibitory effects on NE and 5HT uptake. The concentrations producing 50 percent inhibition (IC₅₀) were 1.4 x 10 …

Leptophos Metabolism In The Rat: An In Vivo Study Of Oxidative Versus Conjugative Modes Of Metabolism, David Richard Hampson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objectives of this research were to examine the metabolism in vivo of the pesticide leptophos in the rat under normal conditions and during inhibition of the mixed-function oxidases and during depletion of glutathione. Glutathione is a cofactor in the conjugation reactions of the glutathione-S-transferases. Both the mixed-function oxidase system and the glutathione-S-transferases have been shown to be important in the biotransformation of other organophosphate pesticides.

Urinary metabolites of leptophos were extracted, derivatized and subsequently analyzed by gas-liquid chromatography. The methods used to analyze for alkyl phosphonates were subject to several shortcomings and modifications of the original procedure were necessary. …

Economic Impacts Of Public Grazing Reductions In The Livestock Industry With Emphasis On Utah, Deevon Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper was to determine the immediate impact of reductions in public grazing on livestock production in the United States. This was accomplished by the use of linear programming techniques. Different grazing reduction simulations were utilized to determine the short and long run effects of across-the-board reductions in public grazing.

The United States was divided into 13 regions. The 11 western states were considered as individual regions. Special emphasis was placed on the effects of grazing reduction on Utah. The availability and utilization of feed and livestock products during a "normal year", 1978, were considered in this …

Nonidentity Matching-To-Sample With Retarded Adolescents: Stimulus Equivalences And Sample-Comparison Control, Robert Stromer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In Experiment 1, four subjects were trained to match two visual samples (A) and their respective nonidentical visual comparisons (B); i.e., A-B matching. During nonreinforced test trials, all subjects demonstrated stimulus equivalences within the context of sample-comparison reversibility (B-A matching): When B stimuli were used as samples, appropriate responding to A comparisons occurred. A-B and B-A matching persisted given novel stimuli as alternate comparisons. However, the novel comparisons were consistently selected in the presence of nonmatching stimuli: i.e., during trials comprised of a novel comparison, an A or B sample from one stimulus class, and an "incorrect" comparison from the …

Structure And Petrology Of Tertiary Volcanic Rocks Near Etna, Utah, Kent W. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three volcanic domes and related volcanic rocks of Tertiary age are located near Etna, Utah, in Box Elder County. The domes follow a north-south trend and are fault controlled. Flow structure indicates a change from a less viscous, flow-forming lava which produced an exogenous dome to a more viscous lava which formed endogenous domes. Associated pyroclastic deposits are negligible. The volcanic rocks are composed of porphyritic rhyolite and rhyolitic vitrophyre having phenocrysts of quartz, sanidine, plagioclase and biotite with minor amounts of Fe-Ti oxides, hypersthene, allanite and calcic amphibole. Quartz and sanidine phenocrysts are generally embayed whereas plagioclase phenocrysts are …

The Assessment Of Consumer Awareness Of Adults, Virginia Anne Haldeman Dickinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The assessment of consumer awareness is important to: 1) identify awareness needs of adults, 2) design programs to meet those needs, and 3) assess changes in consumer awareness as a result of participation in such programs. A search of the literature failed to identify an instrument using recall rather than recognition to assess adult consumer awareness of sources of product/service information, existing consumer protection laws, and possible channels of recourse.

The purpose of this research was to develop a reliable and valid instrument to measure the consumer awareness of adults. The test development study involved 32 respondents from one pre-existing …

Common Use Grazing Studies On Southern Utah Summer Range, Al F. Schlundt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine the average dietary intake of pantothenic acid and correlate it with urinary excretions and the blood levels of this vitamin to assess the pantothenic acid status of the elderly population.

A seven day diet record was obtained from 65 non-institutionalized and 26 institutionalized persons over 65 years of age assessed to be free of chronic diseases. A 24 hour urine specimen and a fasting blood sample was obtained from each study participant. An …

Primary Representational Systems As A Basis For Improved Comprehension And Communication, Alan Thomas "Chip" Mattar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this dissertation was to determine the usefulness of primary representational systems (prs) as a basis for improved comprehension and communication. Primary representational systems were discussed as being cognitive representations of experience which are revealed through auditory (A), visual (V), or kinesthetic (K) language.

Specifically, this study tested Bandler and Grinder's assumption that an identified A, V, or K individual would better comprehend a communication which contained predicates representative of that individual's prs. Comprehension was operationalized into general information (GI) and specific predicate usage (SPU) segments in order to isolate possible group differences on this dimension.

A total …

Evaluation Of Multivariate Homogenous Arma Model, Lucy Chienhua Tseng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this thesis is to study a restricted multivariate AFRMA model, called the Homogeneous Model. This model is defined as one in which each univariate component of the multivariate model is of the same order in p and q as it is in the multivariate model.

From a mathematical respect, multivariate ARMA model is homogeneous if, and only if, its coefficient matrices are diagonal. From a physical respect, the present observation of a phenomenon can be modeled only by its own past observation and its present and past "errors."

The estimation procedures are developed based on maximum likelihood …

Extreme Value Distribution In Hydrology, Bill (Tzeng-Lwen) Chen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problems encountered when empirical fit is used as the sole criterion for choosing a distribution to represent annual flood data are discussed. Some theoretical direction is needed for this choice. Extreme value theory is established as a viable tool for analyzing annual flood data. Extreme value distributions have been used in previous analyses of flood data. However, no systematic investigation of the theory has previously been applied. Properties of the extreme value distributions are examined. The most appropriate distribution for flood data has not previously been fit to such data. The fit of the chosen extreme value distribution compares …

Reproductive Success Of The White-Faced Ibis: The Effects Of Pesticides And Colony Characteristics, Benjamin B. Steele

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reproductive success of white-faced ibis (Plegadis chihi) was measured in nine colonies on marshes in northern Utah during 1979. The effects of pesticides and characteristics of colonies and sub-colonies on reproductive success were examined.

DDE was present in all 80 eggs sampled and had a geometric mean concentration of 1.25 ppm. Shell thickness of 176 eggs was 4.3 percent below pre-1945 thickness. Shell thickness was weakly correlated with residues of DDT, DDE, Dieldrin, and heptachlor epoxide. Residues of these four pesticides were all correlated with each other. However, because of the stronger correlations between shell thickness and two …

An Agro-Sylvo-Pastoral Approach To Desertification Control And Increased Productivity Of The Sahel, Rober D. Kirmse

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The southern arid fringe of the Sahara Desert, called the Sahel, is progressively becoming less productive through a systematic deterioration of the environment. Population increases and technological advances have encouraged ecological degradation through man's normal activities for survival. The degradation process has been referred to as desertification, desertization, desert encroachment, and desert creep.

Recital Report, Gregory John Wheeler

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Two basic ideas underlie the purpose of this recital and report:

(1) There are certain fundamental techniques that a woodwind teacher must employ in his teaching methods. These techniques include: tone production, fingerlings, and articulation, which vary significantly with each of the woodwind instruments. There are many teachers in the field of music education who profess to be skilled on all woodwind instruments, when in fact, their knowledge is limited to one instrument only. With this limited knowledge they attempt to teach techniques and concepts that pertain to all woodwind instruments. Indeed, an educator may have or create many problems …

Characteristics And Genesis Of Some Soils Of The Upper Terraces Of Lake Bonneville, Mohammad Ali Haji Mirsadeghi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The genesis and characteristics of the Timpanogos, Hillfield, and Sterling soils and an unnamed Mollisol (soil formed on north-slope) on the east part of Cache Valley were studied in order to determine (1) why the soil morphology is not chronologically related to the geomorphic surface and (2) why different soils have developed on these surfaces, even though the soil forming factors appear similar.

The particle size distribution of the upper horizons of the Timpanogos, Hillfield, and unnamed Mollisol pedons are relatively similar. These soils developed from stratified deposits with granulimetric composition in which 75 to 90 percent of the grains …

The Population-Food Squeeze: Education For Survival, N. Keith Roberts

Faculty Honor Lectures

One in every four people living on our planet goes to bed hungry each day, and many more survive on inadequate diets only to die prematurely. At the same time, many of the world's natural resources are producing food far below their potential. Almost 25 percent of the Earth's adult population are illiterate, and many more are severely deficient in basic educational skills.
