The Fundamental Groups Of The Complements Of Some Solid Horned Spheres, Norman William Riebe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the methods used for the construction of the classical Alexander horned sphere leads naturally to generalization to horned spheres of higher order. Let M₂, denote the Alexander horned sphere. This is a 2-horned sphere of order 2. Denote by M₃ and M₄, two 2-horned spheres of orders 3 and 4, respectively, constructed by such a generalization.

The fundamental groups of the complements of M₂, M₃, and M₄ are derived, and representations of these groups onto the Alternating Group, A₅, are found. The form of the presentations …

Differential Cross Section For Electron Positron Pair Production From Neutron Proton Scattering, Robert Dalton Wheeler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The differential cross section for a neutron-proton collision forming an electron-positron pair is calculated. The interaction between the neutron and proton is assumed to be pseudo-scalar and that between the proton and the pair electromagnetic. The interaction between the pair and the neutron is assumed negligible.

The methods used to obtain the matrix elements of the process follows that of Möller. The calculation is therefore based on retarded interaction and is relativistic. In obtaining the square of the matrix elements the initial and final polarization states were not considered. The usual projection operator methods were then applied to the intermediate …

The Water Permeability Of Potato Tuber Tissue, Ward Bryce Roberson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments involving pressure, temperature, salt solutions, decenylsuccinic acid, a surfactant, and respiration inhibitors including azide, dinitrophenol, malonate, and iodoacetic acid were conducted to determine the extent to which the cytoplasm of the parenchymatous cells of the potato tuber influenced the tissue's water filterability.

The amount of water or solution moved through the potato tissue was measured by applying a pressure differential to the solution, forcing it across a 1.0 mm thick disc of tissue which was supported in a pressure filtration apparatus. The solution moved was collected and measured directly. In certain experiments the conductivity of dialysis membrane material was …

Factors Associated With The Penetration And Colonization Of Tomatoes By Verticillium Dahliae, Terry Dee Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments have demonstrated that Verticillium dahliae is capable of direct cortical penetration of roots and of subsequent distribution throughout plants of both resistant (Loran Blood) and susceptible (Meteor) varieties of tomato. Plants were inoculated by the root dip method and planted in sterile soil. After one week the fungus was isolated from the upper portions of both the susceptible and resistant varieties as indicated by growth petiole sections plated on PDA. The distribution of the fungus in the resistant plants was irregular, but in susceptible plants the fungus was isolated regularly from all petiole sections. In experiments using disposable growth …

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 …

Distribution Of Macroinvertebrates In The Green River Below Flaming Gorge Dam, 1963-1965, William D. Pearson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was undertaken to determine the effects of rotenone applied during a fish control operation in September 1962 and the installation of Flaming Gorge Dam in November 1962 upon the distribution of invertebrates in the Green River. Since these two events, the river has changed from a warm, turbid stream to a cold, clear trout stream for about 45 miles below the dam. Totals of 234 bottom samples and 394 drift samples were collected between the dam and Ouray, Utah (166 miles below the dam). The species composition of the fauna above Carr Ranch was much simpler during 1964-65 …

Pan evaporation was computed using the Christiansen, Mathison, Blaney-Criddle, Hargreaves, Penman, and Kohler formulas. The computed pan evaporation from these formulas, measured Fuess evaporation, and …

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 …

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 …

A History Of The Italian And German Prisoner Of War Camps In Utah And Idaho During World War Ii, Ralph A. Busco

The United States offered an ideal situation for prisoner of war camps during World War II. The remoteness of the states of Utah and Idaho offered also an ideal situation to intern prisoners.

The United States established 141 base camps and 313 branch camps. Out of this number, Utah and Idaho represented a total number of nine base and twenty-one branch camps. Utah and Idaho had under their supervision approximately 11,660 or 3.6% of the prisoners in the base camps.

The Utah and Idaho camps were under supervision of the United states War Department. Their basic source for the administration …

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

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.

Respiration of flower and leaf buds …

Movement Of Atrazine In Soil Under Furrow Irrigation, Jyothi Veerabhadrappa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Movement of atrazine in response to furrow irrigations was studied using the samples of Timpanogos silt loam soil. Distribution in soil profile of surface applied herbicide was determined by drawing samples of water extracts through porous cylinders. Atrazine quantity was determined by spectrophotometer.

It was observed that the herbicide found in the water extracts was an indication of the quantity present in the soil. The herbicide moved readily with the applied water. Irreversible thermodynamic model could not be applied because of the initial and final boundary conditions. The pattern of movement was in conformity with the chromatographic theory.

The control …

Effects Of Dehydration Processes With Special Reference To Microwave Irradiation On Selected Biochemical And Physical Changes In Apples (Pyrus Malus), Fredoon Shahin Nury

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many innovations have been attempted to shorten drying time or improve dehydration techniques for foods. Despite the recent advances in science and technology the bulk of dried fruit production throughout the world, over 1 1/2 billion tons (dry basis), is prepared by the energy of the sun (Copley and Van Arsdel, 1964). However, other techniques and processes for food dehydration and preservation are occupying more prominent positions in the overall production of dehydrated foods, particularly in the more advanced countries. Economics notwithstanding, it is readily apparent that dehydration as compared to sun-drying offers at least two main advantages. It is …

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 …

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 …
