Ii, Proton Dissociation From Adenosine, Several Monosaccharides And Related Compounds. Iii, Proton Dissociation From Several Pyrimidines And Their Nucleosides At 10, 25 And 40°, Joseph Howard Ryttling

Theses and Dissertations

The log K, ΔH° and ΔS° values for the interaction of several metal ions with the two isomers of the cyclic polyether, 2,5,8,15,-18,21 hexaoxatricyclo[20.4.0.0^9,14]hexacosane are reported. The stability order found for alkali metal ion interaction with either isomer is identical to the order of ion permeability through reconstituted biological membranes for structurally related antibiotics. The size of the metal ion is critical in determining the extent of interaction. A calorimetric titration study of proton ionization from several monosaccharides and derivatives, pyrimidine bases and their nucleosides, adenosine and its derivatives, and cycloheptaamylose is described. The heats of reaction obtained in this …

Comparative Effects Of Carbon Dioxide On Coccidian Oocysts From Five Different Host Species, Thomas David Bunch

Theses and Dissertations

Excystation, as applied to the coccidia, is the process by which sporozoites are released from sporocysts and oocysts. Although this process has long been a subject of interest and study, there still remains considerable disagreement among investigators as to the mechanism by which the process occurs and the factors which are involved.

Physicians' Degree Of Concern As A Function Of Numerical Medical Information Indices, Frederick W. Theye

Theses and Dissertations

The present investigation was essentially exploratory and descriptive in purpose. Utilizing the direct scaling method of magnitude estimation (with assigned modulus) the study attempted to: (1) determine if lawful relationships existed between the clinical judgment of licensed physicians and the results from nine numerical medical information indices, and (2) to quantitatively describe such relationships.

It was believed that direct estimation methodologies have been shown through empirical studies to be superior to the psychophysical models of Fechner and Thurstone. Previous work has also illustrated that the power law of S. S. Stevens' has provided a powerful methodology in studying the topic …

Response And Associative Learning In Warmup, Allen Mayo Raffetto

Theses and Dissertations

Improvement in learning successive lists has been found in both serial and paired-associate verbal learning tasks. Both intrasession and intersession effects have been observed, although it is well established that intrasession effects are greater in magnitude. Intrasession improvement in learning successive verbal tasks has been called warmup. Earlier investigators (e.g., Heron, 1929; Irion, 1949; Thune, 1950) favored an explanation of warmup similar to that used in motor skills learning. They viewed warmup as postural and attentive changes taking place within a learning session. These changes were seen as nonassociative and temporary. Warmup was regarded as separate from intersession improvement, usually …

An Investigation Of A Structural Model Of Small Group Problem Solving, David Dwight Harshbarger

Theses and Dissertations

Past research on the nature of small group problem solving has led to contradictory findings. Using complex problems, Shaw (1954b) found a decentralized interaction structure, i.e.,a group arrangement in which group members can communicate freely, to be most effective in reaching accurate solutions. Mulder (1960), using Shaw's complex problems, found a centralized decision structure, i.e., a group arrangement in which decisions were made by a small proportion of group members, to be most effective in reaching accurate solutions. Hutte (1965), suggested greater accuracy was found when a decentralized decision structure was used in complex problem solving. In none of these …

The Effectiveness Of Cognitive Conflict And Active Participation As Methods Of Inducing The Conservation Of Substance, Leila K. Beard

Theses and Dissertations

This study was concerned with the possibility of training for conservation. With the component elements held constant across all groups, the effectiveness of two methods of presentation, cognitive conflict and active participation, were tested by a pretest-training-posttest procedure using a 2 x 2 design with a common control group. Within the treatment groups, a conflict presentation of addition-subtraction and perceptual components was contrasted with a non-conflict presentation of the same addition-subtraction and perceptual components, each in a separate series. An active manipulation procedure was contrasted with passive participation. Results indicated that conservation responses increased within the treatment groups significantly more …

Rheological Study Of Concentrated Silica Suspensions, Prakash N. Mishra

Theses and Dissertations

Concentrated suspensions of silica in water were investigated using a rotational viscometer and a Zeta-Meter. The viscometric data was analyzed for shear dependence, solid concentration dependence and pH dependence. The data for electrophoretic mobility was analyzed for pH dependence.

The experimental data was applied to the Bingham plastic model and the power law model and the power law model was found to describe the experimental data more closely than the Bingham plastic model. The parameters for these two models were correlated to solids concentration, pH and electrophoretic mobility.

Effect of particle size on apparent viscosity was also studied but no …

The Panama Canal Tolls Question In The Upper-Midwestern Press, Grant K. Anderson

Theses and Dissertations

In 1912, the United States Congress passed a measure which granted free use of the Panama Canal to ships engaged in the coastwise shipping of the United States. Although Great Britain protested that the measure was a violation of the Hay-Pauncefote treaty of 1901, President Taft signed the bill into law. Two years later, newly elected President Woodrow Wilson appeared before a joint session of Congress and requested repeal of the disputed clause. Several months later, Congress concurred in this point of view and repealed the exemption clause. The question arises: What was the reaction of the upper midwest to …

The data from this study show the following: (1) Approximately twenty per cent of instructor responses in selecting the stated principles of the Church on a current issue are incorrect; (2) The ability of the instructors to recognize prophet's statements from non-prophet's statements is seventy-three per cent; (3) Over ninty per …

George Romney In 1968, From Front-Runner To Drop-Out, An Analysis Of Cause, Richard M. Eyre

Theses and Dissertations

The meteoric political decline of George Romney is unparalleled in political history and in the history of presidential campaigning. In the space of one year, the man evolved from the overwhelming presidential favorite of Republicans, Democrats, and Independents alike to a presidential drop out, criticized severely and even mocked by press and public alike.

There are many opinions as to why this phenomenon occurred. The press has opinions, the public has opinions, and the people closest to George Romney have opinions.

A step by step analysis of Romney's campaign casts light on these opinions and completely discredits some while validating …

The Development Of The Juvenile Instructor Under George Q. Cannon And Its Functions In Latter-Day Saint Religious Education, Lawrence R. Flake

Theses and Dissertations

The success of the Juvenile Instructor magazine, called the Instructor since 1929, owes much to the vision and foresight of its great founder, George Quale Cannon. From a small, crude, four-page paper, first published in 1866, the Juvenile Instructor has developed into a far-reaching and attractive publication, touching the lives of countless thousands in 1969. It has proved to be a great implement of religious education to the Latter-day Saint people and fulfilled four important functions in its early years when Elder Cannon was its editor. It served as the official organ of the Sunday Schools, as a voice of …

The Theology Of Thomas Dick And Its Possible Relationship To That Of Joseph Smith, Edward T. Jones

Theses and Dissertations

In her attempt to find a strictly human origin for certain doctrines contained in the Book of Abraham, and the later teachings of Joseph Smith, Mrs. Fawn M. Brodie relies upon the writings of one Thomas Dick. Dick was a nineteenth century Scottish scientist-theologian who wrote several volumes on religious and scientific subjects. It is known that at least two volumes were known to at least some of the early Latter-day Saints, for passages from them were quoted in the Messenger and Advocate. The purpose of this thesis has been to research the entire ten volumes of Dick's writings …
