All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Because of the rapid advancements being made in the field of knowledge, educators, as well as those in other fields, must periodically take inventory. Current practices, policies, and methods must be carefully scrutinized to determine if they are the most effective. The group or class method of instruction is one such area.

A Comparison Of Aspiration Levels Of Students In Ability-Grouped And Randomly-Grouped Schools, George Aaron Jeffs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Grouping students with in the school setting has long been a concern to all those associated with the educative process. Much investigation has been devoted to the position of level of aspiration as influential motive forces for educational, occupational, and social achievement. Many avenues of grouping have been investigated and some very thoroughly. However, research concerning grouping in relation to level of aspiration in the school setting appears to be extremely limited. This study is designed to further investigate this issue. It might be said that this study consists of essentially two phases: (1) the development of instruments for measuring …

A Comparison Of Underachievers And Normal Achievers At The Upper-Elementary And Seventh-Grade Level, M. Nephi Manning

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

That each is born with differing capacities and potentials is self-evident. Both students and teachers should accept as their right and duty the task of bringing to full fruition these latent potentialities.

It is a cause of concern in the nation, among parents and teachers, and in later years among students themselves, that many of our youth fail to achieve that of which they are capable. This is a loss to society and a disappointment to the individual.

The purpose of this study is to add to the growing fund of knowledge concerning factors related to this important area of …

Upper Cretaceous Stratigraphy Of The Central Part Of Utah, Fredric R. Van De Graaff

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rocks of Late Cretaceous age in the central part of Utah are dominantly elastic. In general, the sediments in the west are of conglomerate and sandstone of continental origin; the sediments in the east are of sandstone and shale of marine origin, These rocks were deposited at or near the western shore of a sea which extended from the Arctic to the Gulf of Mexico. The strand line lay in a general northern direction through Utah with land to the west and marine water to the east.

The Mineral Resources Of The Sevier River Drainage, Central Utah, David T. Sanders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A survey of the mineral resources, the economic rock products, and the ground-water reserves of that part of central Utah drained by the Sevier River system was undertaken by the author in the fall of 1960 as a continuation of a research project directed toward the stimulation of economic growth in the state of Utah. The project was initiated in 1959 by Dr. Donald R. Olsen and Dr. J. Stewart Williams, who conducted a similar survey of a five county area in southwestern Utah (Olsen and Williams, 1960).

Through a review of existing literature, preliminary field examination of most of …

Geology Of The Summer Ranch And North Promontory Mountains, Utah, O. Clair Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Summer Ranch and North Promontory Mountains have not been studied in detail geologically, although the surrounding mountains have been extensively investigated. Within the limits of this area, sedimentary rocks of Mississippian through Permian crop out. Sedimentary and volcanic rocks of Tertiary age are also exposed. Extensive Lake Bonneville deposits underlie the valleys and overlap the foothills.

On The Enthalpy And Entropy Of Soil Water, Robert A. Kohl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Just twenty years have passed since the first papers were published on the application of chemical thermodynamics to the soil-water system (11, 14). Since then, soil physicists have used thermodynamics in an attempt to characterize and learn more about this intricate system.

The Effect Of Chelates On Phosphorus Availability And Mobility, Salah Ahmed Tahoun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil-phosphorus relations and plant-phosphorus relations have attracted the interest of many investigators since Liebig introduced his famous theory about the importance of the mineral matters to the plant in 1840. It was soon realized that phosphorus nutrition was a problem not easily solved for two reasons. 1. The added phosphorus fertilizers, soon after soil application are converted by some reactions in the soil to complex compounds far less soluble, consequently less available to the plant. Conclusions about this process led to controversial debates until it was discovered that a general statement covering all soils was impossible since the reactions involved …

Relations Between Transpiration, Leaf Temperatures, And Some Environmental Factors, Ronald Kay Tew

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Transpiration is the loss of water in vapor form from a plant. This is essentially the same process as evaporation except that it is modified by plant structure. Large quantities of water are removed from the soil, transferred through the conducting tissues of the plant, and dissipated into the air each day. As soon as the water is lost to the atmosphere, it becomes unavailable for human use.

Complexing Of Sugars And Polyhydroxy Alcohols With Molybdenum (Vi), Su Chin Kiang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum is very important in the life processes of both plants and animals. It acts as a catalyst in promoting and controlling many biological reactions in living cells, but exactly what it does and how it functions are not well understood. In the past because of the obvious complexity of the reactions concerned and the extremely minute quantities of molybdenum involved, its presence was long undetected. Lately, molybdenum has drawn special attention on account of its effects on metabolic processes, particularly of plants. In this regard, molybdenum has been shown to be present in four enzymes: nitrate reductase (JJ), xanthine …

Molybdenum Chelates Of 8-Hydroxyquinoline-5-Sulfonic Acid, Ellis Ray Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Man has had an intense interest in the role of enzymes in biological reactions for many years. The basic question -- how enzymes are able to function so efficiently -- remains as yet largely unanswered.

Only in recent years has it been discovered that molybdenum is essential for certain biological processes. For example, traces of molybdenum added to certain soils have resulted in spectacular plant growth (1). Four enzymes are known to contain molybdenum: nitrate reductase (2), hydrogenase (3), xanthine oxidase (4), and aldehyde oxidase (5). In each of these enzymes riboflavin is also present as the coenzyme FAD (flavin …

A Matrix Formulation Of The Least-Squares Method And Its Application To Nuclear Decay Schemes, Otto Harry Otteson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many people call physics an ''exact science". This may be true depending on our definition of exact. Most dictionaries include as a definition of exact the words "strictly accurate". The average man thinks of an "exact science" as one which yields "strictly accurate'' results. Physics then is exact only to a degree.

Pfaffian Differential Expressions And Equations, K. Raman Unni

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is needless to point out the necessity and the importance of the study of Pfaffian differential expressions and equations. While it is interesting to consider from the pure mathematical point of view, their applications in many branches of applied mathematics are well known. To mention a few, one may observe that they arise in connection with line integrals (example, determination of work). They provide a more rational formulation of the foundations of thermodynamics as developed by the Greek mathematician Caratheodory. They also arise in the problem of determining the orthogonal trajectories. In many branches of engineering and other physical …

Content, Sequence, And Emphasis Of Arithmetical Concepts As Presented In Six Textbooks And An Analysis Of Student Errors In Fifth Grade Arithmetic, Lorenzo Groutage

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Arithmetic problems and the mastery of such problems play an important role in society as it exists today. The pressure from the public has been and is for better teaching of the basic skills. Public school teachers have often evaded this issue (2). For the past decade the emphasis has been "Why Johnny Can't Read," but it seems equally important, because of the relationship of reading and arithmetic, that the focus also center on the mathematical phase of educa­tion (8).

Prediction Of Academic Success In The College Of Forestry, Ronald Skeen Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The College of Forest, Range and Wildlife Management (hereafter referred to as the College of Forestry) at Utah State University has been concerned for some time with the problem of selecting from the applicants to their school the ones whom they think will be able to complete the requirements for graduation. The large number of freshman students placed on probation at the end of the fall quarter and of succeeding quarters each year fives some idea of the magnitude of the problem. It is not unusual for 40 or 50 percent of the entering freshmen to be in this category.

Soil Moisture As A Factor In Streamflow Forecasting For Logan River, Utah, Yu Kam Fok

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Purpose

Forecasting the annual water supply in an arid area by using the water content of snow on watersheds on some particular date, such as April 1, has become a very useful practice. Although these forecasts have given results of great practical value, they have sometimes been considerably in error. Seeking to minimize error, forecasters have incorporated various additional data such as temperature and antecedent rain to improve the relation between snow measurement and measured runoff.

Numerous methods have been suggested in the search for a reliable streamflow forecasting equation and various data have been used. Nearly all of the …

The Weston Canyon area comprises the southern part of the Bannock Range and northwestern part of the Malad Range in southern Idaho. Geologic investigations of adjacent areas date from 1871. These investigations have led to detailed geologic reports that cover much of the Wasatch Range, Bear River Range, Malad Range, Portneuf Range, and Cache Valley. The geology of the southern part of the Bannock Range, however, has not been studied in detail, and it is the purpose of this investigation to map and describe the geology of the Weston Canyon area and to correlate it with previously described geology of …

The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Naturalists for many years have known that birds sing most at dawn and at dusk, but to which of many physical variables they are responding has not been completely determined. This problem has taken on importance in the field of wildlife management because calling rate has been used as an index of abundance for numerous game birds, namely the Pheasant, Phasianus colchicus (Kimball, 1949); the Mourning Dove, Zenaidura macroura (McClure, 1939); the Bobwhite Quail, Colinus virginianus (Bennitt, 1951; Rosene, 1957): and the Woodcock, Philohela minor (Pitelka, 1943).

A Determination Of The Earth's Gravity Field In Spheroidal Coordinates, M. Spencer Hamilton Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The earth's gravity field G * at a point P in the region surrounding the earth's surface is defined as the force acting on a unit mass concentrated at P. This is a force resulting from two components: (1) G₁ due to the gravitational attraction of the earth's mass, and (2) G₂ due to the earth's rotation.

As a result of Newton's law of gravitation, G₁ can be written in integral form as follows:

G₁ = k ( (_V ( rdm/r³

where r = PQ, r = |r|, Q is a point which ranges …

Influence Of Compaction And Freezing On The Structure And Permeability Of Some Selected Horizons From Northern Utah Soils, Samir Ramzy Nagmoush

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Frequently, in evaluating plant deficiencies, one considers only those soil factors which are associated with the fertility of the soil-- mainly the levels of phosphorus, potash, nitrogen, and organic matter. A certain level of nutrition is essential for plant growth, but in order for the nutrients to exert their maximum influence on the productivity of the soil, it is equally important that a good soil environment be provided and maintained. A good environment requires that good physical conditions of soil, sir, and water be in balance.

The Influence Of Temperature On The Impedance To Water Flow Through Plants, Royal Duane Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This era has been termed the atomic or space age. The greatest concern of most people seems to be centered around survival from the destruction and suffering that might be caused by atomic and nuclear weapons. However, along with this, the world is confronted with perhaps a greater disaster--a potential calamity seldom realized by most people, yet a problem which grows more serious in the world each year--a tragedy which would probably be worse than destruction from nuclear weapons. This encroaching catastrophe is starvation.

Even today the majority of the people in the world do not have enough food. Each …

Moisture And Temperature Effects On The Transformations Of Nitrogen From Applied Ammonium Sulfate In A Calcareous Soil, John Keith Justice

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen has commonly been a deficient element in the cultivated soils of the world since the beginning of agriculture. The general acceptance of the practice of using manures as a means of increasing plant growth, as shown by the records of ancient civilizations, attest to this fact. Since the time of von Liebig there has been an increasing awareness of the importance of this deficiency in soils. As a result of a better understanding of the problem and the increasing availability of commercial forms of nitrogen, a rapid increase in the use of nitrogen fertilizers has taken place in the …

Effect Of Anions On The Sodium Adsorption Capacity And Electrophoretic Mobility Of Sodium Saturated Utah Bentonite, Theron G. Sommerfeldt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sodium saturated Utah bentonite was equilibrated in several concentrations of various sodium salt solutions. The effect of anions on the amount of sodium adsorbed was determined. The effect of anions on the electrophoretic mobility of the clay was also studied. The results are reported herein.

Anions, are generally considered, in the field of surface chemistry, to have no influence on the amount of cations adsorbed or the electrophoretic mobility of negatively charged colloids (5, 10, 28, 41). There is evidence (2, 7, 24, 26, 27, 33) to indicate that anions sometimes have an appreciable effect. If anions influence the amount …

The Effect Of Temperature And Moisture On Nitrification Of Applied Ammoniacal Fertilizer In A Noncalcareous Soil, Merwin Allen Stevens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of nitrogen in world agriculture has been known for many years. But in the past few decades the enormity of the problem of nitrogen economy has been recognized. Along with the recognition of this problem there has developed a great increase in the use of nitrogen fertilizers. Coupled with the increased use of nitrogen there has come about an increasing awareness of the problem involved in the use of nitrogen fertilizers.
