The Photochemical Reduction Of Octacyanomolybdate(V) Ion In Aqueous Solutions, Gordon W. Gray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The photochemical reactions occurring in aqueous solutions of octacyanomolybdate(V) ion, Mo(CN)₈^3-, during irradiation with light of 365 and 436 nm wavelengths were studied. The quantum yields and reaction products were determined for neutral, unbuffered solutions as well as solutions buffered at pH 4.0, 7.0, and 9.0.

The results of these studies showed that the Mo(CN)₈^3- ion is rapidly reduced by light to a Mo(IV) complex. In neutral or acidic media, the initial photoreduction product was found to be the red heptacyanoaquomolybdate(IV) ion, Mo(CN)₇(H₂O)^3-. Photolysis in basic solution gave the …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Corn (Zea mays L.) seedlings possessed a high degree of tolerance to growth inhibitory effects of pre-emergent application of 2-chloro-N-isopropylacetanilide (propachlor), squash (Cucurbita maxima Duchesne) was intermediate in its response to the herbicide followed by oats (Avena sativa L.), lambsquarters (Chenopodium album L.) and redroot (Amaranthus retroflexus L.). Root growth was more severely retarded by lower concentrations of propachlor than was stem development.

Propachlor inhibited cell division in onion (Allium cepa L.) root tips. Aberrations in the mitotic behavior, such as contraction of chromosomes, was also induced. Cell elongation, in particular auxin …

The Effect Of Chemical Competition On Thermodynamics Of Bacterial Adsorption, Deorao R. Khairnar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective of this investigation was to study the effect of chemical competition on thermodynamics of bacterial adsorption. This was done using an experimental system consisting of Mendon silt loam soil as the adsorbent, Staphylococcus aureus as a common adsorbate and sodium chloride (NaCl), sodium lauryl sulfate (SLS), and peptone as competitive adsorbates.

The bacterial adsorption on soil both with and without chemical competition followed Langmuir type isotherms. From the equilibrium data, thermodynamic functions such as free energy, ΔF°, enthalpy, ΔH°, and entropy, ΔS°, were calculated. Observed positive ΔH° values indicated that the bacterial uptake in both noncompetitive and competitive …

Cation Exchange And Transport In Soil Columns Undergoing Miscible Displacement, Sung-Ho Lai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A mathematical model was developed to predict the exchange of one cation by another in a soil column undergoing one dimensional cation solution displacement under steady state flow conditions. The model allowed prediction of both the solution and exchanger phase concentration of the cation in question.

The model consists of a material balance equation which is a parabolic type partial differential equation. The assumption was made that equilibrium was reached instantaneously between the cations in the solution phase and the exchanger phase. This assumption reduced the material balance equation to a form that allowed numerical solution providing the data concerning …

A Study Of The Secant Law For Sporadic E, Ruey-Yuan Han

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The secant law is the relationship between the frequencies of a vertically incident wave and an obliquely incident wave that are reflected from the same level (i.e., density) of a stratified ionosphere. This thesis investigates the validity of the secant law applied to sporadic E.

Sporadic E data from two backscatter sounders and one vertical incidence ionosonde located in Japan were studied to test the validity of the secant law. The B-scan photos of the backscatter sounders were searched for E_s patches which were then compared with the sporadic E parameters defined for vertical incidence ionograms.

Finally, two theoretical …

It was then compared with personality characteristics of a control group representing the remaining student body.

The result was no significant difference between the two groups on any of the MMPI scales.

After checking the activities of the two groups, it was found that the experimental group was lower in grade point average than the general student body, but this …

A Forecast Of Iranian Demand For Agricultural Food Products, Ivan F. Beutler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Domestic demand for Iranian agricultural food commodities was projected for 1970, 1975 and 1980. Demand for particular commodities was projected separately for Tehran (the capital city), urban Iran and rural Iran.

Income and population growth were the most significant explanatory variables in this long term projection.

Two cross-sectional family budget surveys, taken six years apart, provided consumption data for Tehran and urban Iran. A series of family budget studies provided Engel curve data for rural Iran.

The income effect was estimated for each food item by least squares regression analysis. The resulting income elasticities were found to be significantly different …

Production And Marketing Of Sheep On The Bolivian Altiplano: An Economic Analysis, Robert Scott Sly

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was undertaken to evaluate the general sheep marketing process in Bolivia, to determine the present economic structure of farm units belonging to Altiplano sheep producers, to analyze the economics of marketing Altiplano sheep at an earlier age, and to analyze the economics of using various local products as a supplemental sheep feed in Bolivia.

In general the Bolivian sheep marketing process is inadequate and inefficient because of lack of marketing information, poor producer-buyer contact, lack of commercial sheep transportation, slaughterhouses lacking in facilities and hygienic conditions, and apparently unattractive retail methods.

By selling their relatively unproductive male sheep …

An Economic Evaluation Of The Product Sugar With Special Emphasis On The Abnormal Sugar Market Of 1963-1964, Merlin J. Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The product sugar is studied in detail with special emphasis on supply and demand factors, in an attempt to better understand the abnormal sugar market of 1963-1964.

The unusual market fluctuations of that period appear to have been initiated by a statistical imbalance in world supply and demand of sugar.

The extent of price fluctuations in the United States during 1963-1964 were accentuated by the inability of current sugar legislation to shield the U. S. market from the world market, and by the openly aggressive purchasing policies followed by the U. S. Department of Agriculture which further aggravated an already …

Measurement Of The Perceptual Rotation Of Visual Stimuli, Floyd W. Stettler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Apparatus for study of the phenomenon of rotation consisted of two rotating turntables constructed to receive disks for presenting varied visual stimuli. Turntables were graduated into 360 degrees for measurement of angular discrepancy in the task of visually matching rotational positions. Subjects from ages four through eleven attempted to match six compass positions for each of three designs--a boxlike house, a straight line, and Bender-Gestalt Figure No. 3.

Errors of rotation were classed as either transpositional or nontranspositional, Transpositional error, involving reversal or mirroring of the directional aspect of the designs, largely disappeared by age six. Non-transpositional error declined rapidly …

The Effects Of Cholinergic And Adrenergic Chemicals On Drinking Behavior (Thirst), G. Ron Norton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Because of inconsistencies in the research literature following Grossman's (1960) demonstration that drinking behavior (thirst) could be modulated by intrahypothalamic injections of adrenergic and cholinergic chemicals, a series of studies were undertaken to clarify the relation between introducing chemicals into the brain and drinking behaviors.

The first study attempted to determine the effect of water deprivation on post-deprivation drink sequencing. It has been demonstrated that 75% - 90% of the water consumed by normal rats is taken during the evening hours (Fitzsimmons, 1957; Stellar & Hill, 1952). Grossman's (1960; 1962a) studies failed to consider normal drinking rhythms and consequently modulated …

A Report On The Statistical Properties Of The Coefficient Of Variation And Some Applications, Howard P. Irvin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Examples from four disciplines were used to introduce the coefficient of variation which was considered to have considerable usage and application in solving Quality Control and Reliability problems.

The statistical properties were found in the statistical literature and are presented, namely, the mean and the variance of the coefficient of variation. The cumulative probability function was determined by two approximate methods and by using the noncentral t distribution. A graphical method to determine approximate confidence intervals and a method to determine if the coefficients of variation from two samples were significantly different from each other are also provided (with examples). …

A Survey In Mean Value Theorems, David A. Neuser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A variety of new mean value theorems are presented along with interesting proofs and generalizations of the standard theorems.

Three proofs are given for the ordinary Mean Value Theorem for derivatives, the third of which is interesting in that it is independent of of Rolle's Theorem. The Second Mean Value Theorem for derivatives is generalized, with the use of determinants, to three functions and also generalized in terms of n-th order derivatives.

Observing that under certain conditions the tangent line to the curve of a differentiable function passes through the initial point, we find a new type of mean value …

A series of Basic Assembler Language subroutines were developed and made available to the FORTRAN IV language processor which makes list processing possible in a flexible and easily understood way.

The subroutine will create and maintain list structures in the computer's core storage. The subroutines are sufficiently general to permit FORTRAN programmers to tailor list processing routines to their own individual requirements. List structure sizes are limited only by the amount of core storage available.

The Effects Of Formaldehyde On The Frequency Of Reversion Of The White-Ivory Mutant Of Drosophila Melanogaster, Ruth Ellen D. Wood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is an analysis of the effects of formaldehyde, a chemical which is both recombinogenic and mutagenic, on white-ivory (wⁱ) a highly mutable allele of the white locus of Drosophila. Formaldehyde is shown to significantly increase the reversion frequency of wⁱ. The results of this investigation differ from earlier observations in three respects: (1) there is a positive correlation between RNA (ribonucleic acid) concentration and reversion frequency in the presence of formaldehyde, but reversion does not appear to be totally RNA dependent; (2) female germ cells are more sensitive than those of the male; …

An Economic Analysis Of The Predator Problem In The Range-Sheep Industry In Utah, David Murray Curle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The economic effects, to the Utah range-sheep operation and to the economy of the state of Utah, of predation upon sheep were studied by use of a personal interview survey. This survey sampled 20 percent of the range-sheep operations in Utah.

The sheep and lamb death loss from predation was found to be 61.0 sheep and lambs per 1,000 head of ewes in fiscal 1969. The survey. also showed that 71.36 percent of the losses were lambs and 28.64 percent were ewes.

The total economic loss to Utah sheep ranchers was calculated to be 1,062,502 dollars as a result of …

A Study Of Flooded And Rain Infiltration Relations With Surface Ponding, Yehia Z. El-Shafei

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The non-linear partial differential equation (combination of Darcy's law and continuity equation) has been used in this investigation to predict the flooded infiltration through soils possessing appreciable amount of clay and initially drier than its field capacity. One of the most important assumptions made in solving the differential equation is that the capillary conductivity-moisture content relationship is unique for each initial moisture content computation due to the different reaction of clay minerals with different initial moisture contents.

Mathematical equations were also derived to predict:

1. The rate of the wetting front advance, prior to the occurrence of surface ponding, taking into …

Effects Of Sublethal, Cerebral X-Irradiation On Movement And Home-Range Patterns Of Black-Tailed Jackrabbits, Lewis Nelson Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Effects of sublethal, cerebral irradiation on movement and home-range patterns of black-tailed jackrabbits were studied in Curlew Valley, Utah, using radio-telemetry. Irradiation of 70 captive animals indicated that the LD₅₀₍₃₀₎ was between 5,556 and 6,200 roentgens.

Nine wild, free-living experimentals were trapped in desert terrain, irradiated, transmittered, and released at the capture sites. Seven wild controls were treated similarly but were not irradiated. The field-irradiation dosage was 5,000 roentgens.

Tracking accuracy was determined by telemetering transmitters at fixed locations. Mean hourly movement was measured within 20-30 percent error and home ranges were measured with an error of less than …
