The Dynamics Of Duopoly, Gordon E. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A monopolist, knowing the demand curve for his product, can in a given period produce the quantity of this product which will maximize his profit. Any larger or smaller quantity will result in less profit. When another manufacturer starts producing the same or similar product, a duopoly result. The new manufacturer, in order to maximize his profit, according to Cournot, will choose a quantity that is derived on the assumption that the original manufacturer's quantity will remain fixed.

Simultaneous Movement Of Water And Herbicides In Unsaturated Soils, Ming-Shyong Yang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since weed killers were developed in the early part of the decade beginning in 1940, herbicides have been increasing in use until they are now widely used to control weeds. The application of herbicides has thus become a regular agricultural and ecological practice.

A Study Of The Structure Of Shear Turbulence In Free Surface Flows, Maddineni Venkateswara Rao

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Turbulence is a familiar phenomenon which gives rise to complicated problems in many branches of engineering. Hinze has set forth the following definition for turbulence: "Turbulent fluid motion is an irregular condition of flow in which the various quantities show a random variation in time and space coordinates, so that statistically distinct average values can be discerned." Osborne Reynolds (1894) was the first to introduce the notion of statistical mean values into the study of turbulence. He visualized turbulent flow as the sum of mean and eddying motion. By introducing this sum of mean velocity and fluctuating velocity into the …

Estimation Of Pan Evaporation And Potential Evapotranspiration Of Rice In The Central Plain Of Thailand By Using Various Formulas Based On Climatological Data, Paitoon Palayasoot

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water has become one of major national concerns, and it is the limiting factor in the expansion of an irrigated agriculture. Irrigation development is rapidly growing all over the world. New lands are being brought under irrigation and older irrigation lands are being improved. In the planning and operation of an irrigation project, the estimation of water requirements and evapotranspiration, or consumptive use, requires careful consideration. A knowledge of evapotranspiration is playing an increasingly important part in irrigation science. It is the best index of water requirements which represent the amount of water that should be applied by irrigation for …

Factors Related To First Year College Success In A Selected Group Of Scholarship Recipients, Laverl C. Giles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The idea of a scholarship program is almost as old as the oldest institution of higher learning. The universality of such a program is almost completely comprehensive throughout the world. Although the purpose of scholarship programs has varied as much as each of the institutions varies, in most of the situations the programs have been well acclaimed. The success of these programs in terms of the student has often been tested or at least scrutinized. This type of study has been attempted several times. However, both Harris (11) and Endler (7), in reviewing the literature from 1931 to 1959, report …

The Programmed Text As An Aid To Teaching Spelling In Junior High School, Gordon Howard Nicholls

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Organized education, historically, has been slow to commit itself to any sort of intensive examination of how learning can be both analyzed and substantially improved. But today Komoski (1960) tells us that we are looking beyond the traditional approaches to teaching. If a newly developed method is shown to be more effective than the techniques which have traditionally been employed, it is carefully considered for incorporation into the current education program.

Programmed instruction is just such an example of a recently developed teaching method which claims it will contribute much to education. It dates back to Pressey's report (1926) of …

The Verbal-Quantitative Differential As An Indicator Of Personality Maladjustment, Robert W. Spencer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Counseling centers at many universities are constantly trying to improve their value to the universities by identifying the students who have problems, and by making known to students the services that are available. Since many counseling centers are in direct contact with large numbers of students during the admissions testing program, it would seem that data gathered at this time should be carefully examined for clues that would aid a student in making a healthy and profitable adjustment to his university environment.

Flume Study Of The Effect Of Concentration And Size Of Roughness Elements On Flow In High-Gradient Natural Channels, Mohamed Wafaie Abdelsalam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent years investigators have given increased attention to flow in natural, high-gradient, rough, open channels. Studies include work in both the laboratory and in the field. Solutions to the problem are still incomplete; however, continued attention by investigators is needed to answer many questions. Using a laboratory flume, the writer studied one of the questions concerning the relative importance of gross velocity fluctuations versus turbulent mixing, and the ranges of each under different ranges of submergence and kineticity of flow. In the different ranges, the effect of size and concentration of the roughness elements was studied.

Barypact Topological Spaces, Bradley Y. Maughan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recently, Kimber [3] has discovered a general class of topological spaces, the members of which are termed barypact spaces, that includes the compact topological spaces. This class is distinct from the set of all compact topological spaces, but its members possess many of the useful properties associates with compactness. As a consequence, several standard compactness theorems become special cases of corresponding theorems in a more general setting and the techniques of proof applied to these extensions provide new, and sometimes remarkably simple, proofs of the very theorems they generalize. The purpose of this paper is to extend to this …

Formulation Of Error Structures Under Non-Orthogonal Situations, Justus Frandsen Seely

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To gain an appreciation or understanding for the title of this study we must first understand what the phrases "non-orthogonal" and "error structure" mean. With an understanding of these terms the title of this study will become clear.

To obtain an understanding of the term non-orthogonal, consider an experiment where differing treatments are applied to groups of experi­mental units in order to observe the differential treatment responses. If an equal number of experimental units are in each group, then we say we have an orthogonal situation. This means that when equal numbers exist among the experimental units, that the variability …

Error Structure Of Randomized Design Under Background Correlation With A Missing Value, Tseng-Chi Chang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The analysis of variance technique is probably the most popular statistical technique used for testing hypotheses and estimating parameters. Eisenhart (12) presents two classes of problems solvable by the analysis of variance and the assumption underlying each class. Cochran (9) lists the assumptions and also discusses the consequences when these assumptions are not met. It is evident that if all the assumptions are not satisfied, the confidence placed in any result obtained in this manner is adversly affected to varying degrees according to the extent of the violation.

Spectral Analysis Of Time-Series Associated With Control Systems, Karl Leland Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The progress of science is based to a large degree on experimentation. The scientist, engineer, or researcher is usually interested in the results of a single experiment only to the extent that he hopes to generalize the results to a class of similar experiments associated with an underlying phenomenon. The process by which this is done is called inductive inference and is always subject to uncertainty. The science of statistical inference can be used to make inductive inferences for which the degree of uncertainty can be measure in terms of probability. A second type of inference called deductive inference is …

Boolean Space, Tzeng-Hsiang Sun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

M. H. A. Stone showed in 1937 and subsequently that many interesting and important results of general topology involve latices and Boolean rings. This type of result forms the substance of this thesis.

Theorem 4, page 11, states that for any r ≠ 0 in a Boolean ring, there exists a homomorphism h into I₂ , (the field of integers modulo 2), such that h(r) = 1.

Theorem 3, page 6, states that any subring of a characteristic ring of a Boolean space X is the whole ring if it has the two points property (that is, given x, …

Effect Of Calcium Availability On Alfalfa Grown In Calcareous High Sodium Soils, Harry Irving Nightingale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In soil science we shall always be confronted with reactions in soils that involve Ca. Early recognition of this led to experimentation in this area. Due to the fact that Ca deficiency is most common in acid soils, the majority of the experimentation has in the past been largely confined to acid soils and their soil-Ca-plant relationships. There has been relatively little research done with Ca and its availability problems associated with alkaline or sodic soils.

Thermochemistry Of Cyclophanes, Chyi-Feng Shieh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The syntheses and properties of various cyclophanes have been extensively investigated by Cram and others. The paracyclophanes are compounds in which benzene rings are linked to each other by two saturated chains at the para positions, as in structure I. When they are joined to the meta positions, they are called metacyclophanes.

The Kinetics And Mechanism Of The Reaction Of Molybdenum(V) With Iodine, Oxygen And Nitrate, Ervin Park Guymon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum compounds present a series of baffling chemical puzzles. By no means are all of these yet even clearly defined and many may never be. This complexity results from the ability of molybdenum to form six different oxidation states, which can possess three different coordination numbers. Furthermore, molybdenum compounds readily disproportionate to yield mixed valence compounds; and finally, molybdate ions readily aggregate in solution to form a variety of polyions by polymerization-condensation reactions which are controlled by pH and the concentration of the system. Molybdenum's complexity can best be summed up in the words of the late Edgar Smith who …

Effect Of Fluoride On Respiratory Enzymes In Soybean Leaves, Arthur Chiu-Eng Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are many reports relating the effects of fluorides on plant respiration. Fluoride has been regarded as an inhibitor of respiration. Warburg et al. (1942) demonstrated that fluoride inhibited enolase activity, therefore, decreased the respiration rate of yeast. Miller (1958), found a similar inhibition of enolase from pea seed. Bonner (1948), Bonner and Wildman (1946), and Laties (1949) reported that the fluoride ion in culture solutions reduced the respiration rate in Avena Coleoptile, spinach leaves and barley roots. Since the inhibition was reversed by the addition of pyruvate, they concluded that the inhibition of respiration was due to the inactivation …

Evaporation And Potential Evapotranspiration In Central Iraq, Ala H. Al-Barrak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The principal objectives of this study were to compare several formulas for estimating pan evaporation and evapotranspiration and to derive new formulas or modify existing formulas that will better fit the data for central Iraq. Computed evaporation was compared with measured evaporation by determining the differences and the ratios. The pan evaporation formulas were also compared by expressing them all in the form
Ev = K C_RC_TC_WC_HC_DTC_SC_M

Three pan evaporation formulas were modified. For the Meyer and Utah formulas, the constants were changed and expressions were derived …

Simplified Approach To The Problem Of Stability Of Soil Slopes Under Horizontal Earthquake And Pore Pressure, Dalim Kumar Majumdar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A problem that has confronted engineers for a great number of years is that of determining the stability of soil slopes. Many factors introduce complications into stability analysis. Most embankments contain heterogeneous soils, often of several types. This and other complications usually necessitate the use of a simplified cross section. At the same time, it is often necessary to adopt simplified average soil characteristics which represent actual characteristics as best as possible. Those steps which bear on the choice of the simplified section and the simplified soil characteristics are always important in stability analysis work. These steps are independent, however, …

Temperature Dependence Of Soil-Moisture Potential, Jacob Willem Kijne

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teachers have noticed that children draw only those objects which they know by name. Doubtless the adult has a similar tendency, exemplified by the researcher, to limit his observations or to relate them to that which can be expressed in the terminology of an existing or newly developed theory. In this thesis the data obtained from studies of the temperature and pressure dependence of the relative vapor pressure over moist soil samples are analyzed by a thermodynamic approach. Not all of the results can be explained completely by means of this tool. Natural systems, such as a moist soil, are …

Demand For Household Water In Northern Utah, 1962, Seth H. Schick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water is not a single use resource. It can be used for completely unrelated purposes. There are four general uses for water: household, industrial, agricultural, and recreational. Since water is an economic good it must be properly allocated among the four uses to maximize the returns to society. Also, There must be proper allocation among competing units within each major use.
