Description And Evaluation Of Institutions Involved In Water Allocation And Distribution In Utah, Kimber C. Webb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water development and allocation have been among the most important problems Utah has had to face throughout the past 117 years of development . When Utah's first white settlers, the Mormon pioneers, entered Salt Lake Valley in July of 1847, little met their eyes to entice their stay. The earth was so parched and dry that they were unable to scratch the surface with their plows. Less than two hours after their arrival members of the party began digging ditches and building dams to irrigate and soften the earth so they could begin plowing.

Seasonal, Diurnal And Species Variation In Forage Moisture Content In Relation To Site On Mountain Summer Range Of Northern Utah, Chaudhry Mohammad Sharif

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Practical assessments of range production and utilization are based on forage weight estimates. In preparing these estimates moisture content in green vegetation offers some problems. The moisture component is not likely to be constant for a given species. Diurnal, seasonal and site variability have been well illustrated for agronomic and tree species (Salisbury, 1848; Jenkins, 1879; Miller, 1917; Pearson, 1924; Watkins, 1940; Parker, 1951; Ackley, 1954; Werner, 1954; Zohary and Orshan, 1956; Slatyer, 1959; Kozlowaki, 1965 and Jame son, 1966). Since variability is also likely for range plants, computations made on green weights are apt to be fallacious. It is …

Control Of Behavior Through Reinforcement Menus, Gary Lyndle Holt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reinforcement menus were used to change response probabilities while maintaining control over two ''trainable," female, mentally retarded children.

An empirically determined reinforcement menu representing high probability behaviors, five for S₁ and four for S₂, was used in a contingency management system. Instructions were given concerning the contingencies for obtaining reinforcement. Subjects were allowed the opportunity to engage in a high probability behavior only after successful completion of fixed units of reading or arithmetic tasks. After stable performance was established, four additional menus were prepared to approximate in increasing degree, low probability behavior. Measurements were taken of task …

Therefore, some methods and techniques for estimating the amount of water available for development of these small units is needed .

The purpose of this study is to use the concepts and techniques of statistical analysis to develop equations which are useful in estimating the water yield of watersheds for which no stream flow records are available . The approach is an extension of earlier studies at Utah State University (1, lQ) in …

Topics In Semigroups, Merlin Ray Jenson

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

The semigroup theories of fundamental importance were discovered in 1928 with the publication of a paper by A. K. Suschkewitsch. The paper is included in the only book published prior to 1961 dealing primarily with the algebraic theory of semigroups. The book written by the above author and published in 1937 is entitles "The Theory of Generalized Groups."

Since 1940 the number of papers on semigroups has increased to approximately 30 per year. Thus we find ourselves in the midst of a new and expanding area of mathematics. Our interest centers around the structure of semigroups and their representation by …

Numerical Approximations To The Cumulative Chi-Square Distribution, The Cumulative T-Distribution And The Cumulative F-Distribution For Digital Computers, Grace Yuan-Chuen Wang

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

There are good tables of the frequently used cumulative frequency distributions. These tables have some limitations with respect to the number of percentage points that are available. The main drawback in computer usage of these tables is that large amounts of storage and elaborate search and interpolation techniques are necessary for their use.

It is the purpose of this study to present associated numerical methods for digital computer which are satisfactorily accurate and which are reasonably economical in both time and machine memory capacity. To carry out this objective the following procedures were used:

1. A review of literature on …

Comparative Effects Of Dehydration Processes On Physico-Chemical Changes In Fruits, Chang Yong Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Drying with the help of sun and wind is one of the oldest methods of food preservation known to man, but artificial drying, or dehydration, has been developed and used extensively only during the last two decades. The problem in dehydration is that the water content must be decreased sufficiently to maintain the stability of the product by retarding the rates of deteriorative biochemical, microbiological, and enzymatic reactions during subsequent storage. At the same time irreversible changes should not be brought about.

A Study Of The Relationship Between Anxiety, Manifest Needs, And Creativity In Upward Bound Students, Neal A. Davidson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous investigators have indicated that low socio-economic students have difficulty experiencing success on tests heavily loaded with verbal material. Differences in personality characteristics between students of high and low creativity have also been found. The purpose of the present study was to investigate the influence of manifest needs and anxiety on creative thinking.

The Taylor Manifest Anxiety Scale, which determines anxiety level, the Edwards Personal Preference Schedule, which measures manifest needs, and the Torrance Tests of Creative Thinking, which provides an index of creativity were administered to Spanish-American, Anglo-American, Negro, and Navaho high school students, who constituted the 1967 Upward …

Estimation Of Incoming Radiation From Extraterrestrial Radiation And Climatic Data, Rodrigo H. Pizarro

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Average monthly values of incoming radiation, extraterrestrial radiation, sunshine, and sky cover frorn 32 climatological stations in the United States were used as a basis to develop radiation equations.

Empirical relations between incoming radiation and more commonly available climatic and geographic variables, such as percent of relative sunshine, mean daily sky cover, station elevation and extraterrestrial radiation, were established using an empirical procedure used by Christiansen (1966, 1967) to compute his evaporation and evapotranspiration formulas.

The reliability of the equations developed was deternlined by comparing the computed values of incoming radiation with measured values at Davis, California and for the …

Development Of Leading Indicators For Housing Starts In Tremonton, Utah, Douglas I. Ward

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The possibility of developing leading economic indicators of housing starts, on a localized basis, was studied in Tremonton, Utah, for the period from 1958 to 1965. Data on any economic variable which might show a leading relationship to housing starts was gathered and synthesized to ascertain any predicting tendencies.

Several of the variables researched, particularly contracts awarded to Thiokol and Thiokol employment, showed a high positive correlation to housing starts; however, none showed any consistent leading pattern.

An accelerator relationship was found to exist between the average rate of change in Thiokol employment and housing starts. This finding, though not …

The Influence Of Thermo-Gradients Upon Water Movement And Retention In Unsaturated Soils, Jose V. Salazar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Temperature differences of about 5, 10, and 15 V, were applied to uniformly packed and insulated horizontal column of Millville silt loam soil using mean temperatures near 13, 14, 15, 16, 17, 18, 19, 20 and 23.5 C. The temperature distribution along the soil column was determined using copper constantan thermocouples. Soil samples were taken to determine volumetric moisture content, and soil water potential, using the vapor pressure psychometer technique. The thermodynamic flow equation of Taylor and Cary, (1964) was used to calculate the hydro-thermal transfer coefficient (ß) as given by:

-ß = d(μ_w)_T / dlnT

The Impact Of European Economic Integration On Israel's Export Of Oranges In 1970, Moshe Gottlieb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is an attempt to evaluate quantitatively as well as qualitatively possible future developments in international trade of oranges and tangerines, and the possible impact of these developments on the export of oranges and tangerines by Israel.

After World War II, international trade in oranges and tangerines increased rapidly, mostly as a result of the rapid rise in standards of living and the improvements in diet habits which took place in many countries at that time. These favorable marketing conditions encouraged the planting of new groves in the citrus growing areas of the world and particularly those of the …

Student Understanding And Use Of Tobacco In Selected Schools Of Cache County, Utah, Kirk E. Brotherson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Student understanding and use of tobacco was studied under the following specific areas: specific knowledge as it relates to smoking and health; student opinions and attitudes toward smoking; smoking experience; and the influence of certain factors on smoking status.

About 700 students were sampled with the use of a questionnaire. The number of students was divided about equally among four schools and between boys and girls at each grade level, grades seven through twelve. It was found that boys were better informed than girls about tobacco as it relates to health. Also, the senior high school students were better informed …

The Influence Of Hot Brine On The Calcium Content, Score, And Physical Properties Of Low-Fat, Cheddar-Like Cheese, Robert V. Ogden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two factors that are important in the production of the typical body and texture of cheddar cheese are acid development and milk fat content. When either of these is absent or present in less-than-normal amounts, the resulting cheese shows marked defects of curdiness and firmness.

When acid development in a vat of cheese is arrested, it is referred to as a "dead" vat. The cheese from this vat may be salvaged by use of the hot brine method of treatment. Hot brine treated cheese, although lacking the desired acid development, is a reasonably acceptable product, having the desired characteristics of …

Heat Denaturation Of Serum Proteins In Skimmilk And Whey As Measured By The Harland-Ashworth Test, Lynn Verl Ogden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Milk serum proteins have been shown by other workers to be partially protected from heat denaturation by the presence of milk solids (8, 15, 16) and whole caseinate (14). This study revealed that some serum proteins (B-lactoglobulin), as shown by the Harland-Ashworth test (14, 17), were more readily denatured in skimmilk than in rennet whey. A comparison of the heat denaturation rate of serum proteins in whey as opposed to those in whey containing 2.5 percent isoelectric casein was also studied. A striking protection of serum proteins seemed apparent in the presence of isoelectric casein. However, it was learned that …

Amino Acids As Precursors Of Volatile Components In Tomato Fruit, Ming-Ho Yu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The composition of tomato fruit at nine different maturity stages was studied. The dry matter content decreased gradually, whereas the alcohol soluble material and non-protein nitrogen increased with ripening. Total nitrogen decreased up to the large green stage and then increased during ripening. Starch accumulated until nearly the large green stage and then diminished rapidly. Of the two components of starch, amylose decreased much faster than amylopectin, and the ratios of amylopectin and amylose thus increased during ripening. Among the amino acids, glutamic acid was present in an exceptionally high concentration, and its concentration doubled as the fruit ripened. A …

The Biosynthesis Of Aminolevulinic Acid In Relation To Iron And Enzyme, Daniel Ming-Yi Teng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The survey of plant species for aminolevalinic acid synthetase (ALAS) source was conducted. Under the conditions of this study, spinach leaves were found to be a good source of ALAS activity. The amount of amino levulinic acid (ALA) synthesized by the plant extracts was very small and was rapidly metabolized to porphyrins. ALA and porphyrin synthesis was found to be confined to the particulate fractions. Rupturing of the particles with ultrasonifier enhanced the penetration of succinyl-CoA and increased the activity. Direct study of the ALAS activity was enabled by the utilization of C¹⁴-compounds to the isolation by column …

Seed Size As Related To The Selection Of Alfalfas Resistant To The Seed Chalcid Bruchophagus Roddi, L. S. Rogers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several studies have been made by others to try to find a better method of selecting alfalfa that is resistant to seed injury by the alfalfa seed chalcid. This study investigated the possibility of using seed size as a basis of selection for resistance.

Data in this thesis show that the stage of seed development when chalcid oviposited in the seeds did affect the size of seeds. Larger seeds were infested when alfalfa seed chalcid were introduced early in the development of seeds (five days after pollination), and the total number of seeds produced was slightly greater when chalcids were …

Alkali Liberated Phenolic Acids From Alfalfa, Leslie Huey-Seng Huang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fourteen compounds were isolated from an alkaline hydrolyzed extract of alfalfa leaves by using cellulose thin layer plates. The R_f values, fluorescent characteristics, and color reactions were given for all the compounds isolated.

Eight of these were identified as trans-ferulic acid, trans-p-coumaric acid, trans-caffeic acid, o-coumaric acid, tricin, syringic acid, cis-ferulic acid and cis-p-coumaric acid. The identity of the compounds was confirmed by comparison of the R_f values on thin layer chromatograms, fluorescent characteristics under ultraviolet light, and color reactions of spray reagents with those of authentic samples. Three of …

A research experiment was performed in the Utah State University Child Development Laboratory on a group of pre-school children consisting of ten boys and ten girls between the ages of three and four years in an attempt to discover that teaching method which will best sustain a child's interest while teaching a foreign language in an experimental situation.

The procedure involved the evaluation of three different methods. 1) German conversation in a group utilizing audio-visual aids, 2) Group singing of a German song, and 3) Telling a story in German using a flannel board with illustrations. These three methods were …

Development Of A Drainage Function For The Transient Case, And A Two-Dimensional Ground-Water Mound Study To Evaluate Aquifer Parameters, Seid Abdollah Jenab

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A drainage function, D (u_n), is developed to describe the rate of fall and the shape of the water table between drains for an infinite series of parallel drains. The drainage function is evaluated and presented graphically for design purposes. The solution of the drainage function is compared with the solution of Glover's transient state drainage equation. The two equations agreed very well, but the agreement was not as good for very high values of √(4αt)/ L.

The drainage function, D (u_n ), was solved for the point midway between drains and the solution was presented graphically …

Newspaper Advertising, Retail Pricing Practices, And Gross Retail Margins For Turkeys In Selected Utah And Other U. S. Markets For Various Years And Seasons, Gerry R. Flake

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Newspaper advertising and retail pricing practices for turkeys were ascertained and gross retail margins established for three Utah markets, 1955 to 1966, and for 12 other selected U. S. markets, 1965 and 1966.

Turkey was extensively used as an advertised special item, particularly in holiday seasons. Food retailing organizations advertised turkey at low prices and margins at Thanksgiving and Christmas when consumer demand for turkey is traditionally strong. Prior to these holidays, food retailing organizations in a market simultaneously advertised turkey at identical prices and with little product differentiation thus limiting the effectiveness of turkey as an advertised item to …

Economic Analysis Of An Iranian Water Development: The Sefeed Rood Project, Malek M. Mohtadi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is an evaluation of the methods and assumptions employed by those groups responsible for preparation of the original benefit/cost data describing the Sefeed Rood project. Benefit/cost ratios reported by the French engineering firm, Cotha Sogreah, and Plan Organization in a joint study range from 2:1 to 2.6:1 (6 and 10). A priori these seem suspect since the dam plus necessary canals and diversion works are obviously large and costly and only primary benefits are considered. The question is whether the potential benefits are likely to ever yield a positive return on investment and, if so, how long a …

Automated Circulation Control For The Utah State University Library, Richard M. Montgomery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This package of programs is a result of the U.S.U. Library incorporating an automated control on the circulation of their books, which would provide the library with a daily record of all books in circulation, or not available for circu­lation, and send notices when books were overdue.

Because of the long-range program of the Data Processing Department of the University, it was decided to develop the software for this project rather than purchase the hardware.

A Study Of Cotyledonal Cracking In Snap Beans (Phaseolus Vulgaris L.), John L. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Certain varieties of snap bean, Phaseolus vulgaris L., seeds are very susceptible to cracks that develop naturally across the cotyledons during pre-harvest, storage, or germination. This phenomenon is commonly known as cotyledonal cracking and may cause serious yield reductions on plants developing from affected seeds.

Cotyledonal cracking susceptibility of six white and six colored seeded varieties of snap beans were compared. Considerable differences were found in cracking susceptibility, but there was little or no relationship between seed coat color and cracking susceptibility.

An experiment was conducted to determine if a metabolic stress of the plant during the time of pod …
