Lake Bonneville History In Cutler Dam Quadrangle, Cache And Box Elder Counties, Utah, G. Glayde Maw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

When Lake Bonneville spilled through Red Rock Pass at the north end of Cache Valley, the major part of the lake in Salt Lake Valley had to drain from west-to-east through Cutler Dam Quadrangle. Here two major saddles connect the two valleys: (1) Bear River Narrows, at about +4380 feet; and (2) Cache Butte-Wellsville Mountain Pass 4.2 miles south, at about +4970 feet. Spillover levels at both places are cut into older rocks.

Only two morphostratigraphic units are recognized widely in the quadrangle. These represent high stands at the Bonneville level (+5180 ± 20 feet) and at the Provo level …

Occurrence And Distribution Of Invertebrates In Lower Logan River, Nancy A. Erman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of bottom invertebrates on the lower Logan River, Logan, Utah was conducted from June 1966 to July 1967. One objective was to evaluate on a qualitative and quantitative basis the invertebrate populations above and below a sewage entry in the river. Another objective was to study the year-round fluctuations in the invertebrate population.

The greatest variety of invertebrates was found in the summer. Chironomidae and Baetis were the only two groups found in abundance over the entire year.

Populations were reduced during autumn when water levels rose, and they declined even more sharply during the spring flood.

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 …

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 …

Variation In The Order Of Presentation Of Cues As One Variable In Concept Organization, John E. Genasci

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the experiment, with forty-eight students as subjects, a series of nonsense syllables (DAX, MEF, TOV, VIC, YOP, ZIP, and ZIL) were to be associated with four geometric figures. The task was so arranged that Zip applied to all figures, Dax and Vic to subsets of two figures each, and the remaining were individual labels. In each of three experiments there was an experimental group that received pre-response cueing by means of an analogy which involved hierarchic concepts in the same general form, i. e ., animal, wild, tame, and individual names.

The results suggest that the order and timing …

Venison Flavor: The Free Fatty Acid Content Of Fat From Lean Meat Tissue, Von T. Mendenhall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Millions of pounds of venison are harvested each year in the United States. Over 12,000,000 pounds of dressed venison are harvested during the regular season each year in the State of Utah. The hunters of venison contribute approximately 10 1/2 billion dollars to the economy of the state for licenses, lodging, transportation, and other expense of hunting. In many cases this source of meat is a significant part of the household meat supply. Venison is often wasted, however, because of its undesirable flavor. The lack of knowledge as to the causes of variation in venison flavor has prompted this study. …

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 …

An Exposition On Bayesian Inference, John Laffoon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Bayesian approach to probability and statistics is described, a brief history of Bayesianism is related, differences between Bayesian and Frequentist schools of statistics are defined, protential applications are investigated, and a literature survey is presented in the form of a machine-sort card file.

Bayesian thought is increasing in favor among statisticians because of its ability to attack problems that are unassailable from the Frequentist approach. It should become more popular among practitioners because of the flexibility it allows experimenters and the ease with which prior knowledge can be combined with experimental data.

Design Optimization Using Model Estimation Programming, Richard Kay Brimhall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Model estimation programming provides a method for obtaining extreme solutions subject to constraints. Functions which are continuous with continuous first and second derivatives in the neighborhood of the solution are approximated using quadratic polynomials (termed estimating functions) derived from computed or experimental data points. Using the estimating functions, an approximation problem is solved by a numerical adaptation of the method of Lagrange. The method is not limited by the concavity of the objective function.

Beginning with an initial array of data observations, an initial approximate solution is obtained. Using this approximate solution as a new datum point, the coefficients for …

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 …

An Investigation Of Methods For Estimating Marginal Values Of Irrigation Water, Richard L. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Marginal values of water used in irrigation are needed if water is to be optimally allocated among alternative uses. Cobb-Douglas production function analysis and linear programming methods were studied in this investigation to find their fruit-fulness in predicting these marginal values. The theoretical properties of both methods indicate that they are conceptually capable of yielding valid marginal value estimates for irrigation water.

Further investigation of the two methods was carried out as an empirical test in the Milford area of Utah. Marginal values of water used for irrigation in that area were estimated by both procedures. Although inviolable criteria for …

The Effect Of Changing Temperatures On Hardiness, Respiration, And Intensity Of Rest Of Dormant Peach And Apricot Buds, Anthony H. Hatch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

studies were conducted to better understand the influence of temperature on the rest period of dormant peach and apricot buds. Gleason Elberta peach and Chinese apricot trees in the field at Howell Experiment Station in Ogden were used to evaluate rest intensity, respiration, and cold hardiness in relation to temperature.

A rest intensity curve was obtained for both species using various concentrations of gibberellic acid. It was found that temperature had no direct effect on the depth of rest and that the depth of rest had no measurable influence on respiration and cold hardiness.

Experiments On The Inactivation Of Zinc By The Mineral Fractions Of The Soil, John J. Hassett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Zinc deficiency, in many cases, is closely related to organic matter decomposition. DeRemer and Smith (1964) studied the effects of decomposing sugar beet tops on the reactions of Zn⁶⁵ in a Portneuf soil. They found that with time the Zn⁶⁵ associated with lime minerals, exchangeable, and water soluble fractions of the soil decreased, while that found with the organic and mineral fractions increased. This increase in the mineral fraction is of particular interest, since the majority of the Zn⁶⁵ was found to be with this fraction after a period of time. They also showed that the increase …

A Study Of The Natural Rubber Industry, With Special Reference To Thailand, Suratana Vayagool

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relative share of natural rubber in the world's total rubber consumption had been decreasing from 75 percent in 1948- 1949 to 44.4 percent in 1965. Since the production of natural rubber has been rising over the same period, some predictions have been made indicating that there will be a surplus of production over consumption of natural rubber in the near future.

In the world output of natural rubber industry, Thailand ranks third, being surpassed only by Malaysia and Indonesia. Of all the exports of Thailand, rubber ranks second in value and is exceeded only by rice. Almost all of …

A Study Of Input-Output Adjustments, Charles W. Briggs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of using the United States input-output table to explain Israel's economic structure was studied, by comparing price data generated on the basis of the U. S. tables and prices observed in the two countries. A substantial difference between prices generated and observed led to the conclusion that the technological structure of the United States cannot be used to approximate Israel's structure.

Various adjustments were then applied to the United States coefficient matrix to determine if it could be transformed into a new technological structure which would more closely approximate Israel's economy.

Significant improvements were noted by three of …
