The present investigation is concerned with determining the role of calcium, phospholipids, and phospholipid metabolites on transepithelial sodium and water transport in response to antidiuretic hormone (ADH). These studies utilize the frog skin for determining sodium transport and amphibian urinary bladder for water flow measurements and scanning electron microscopy of cell surface morphology. The results demonstrate that phospholipids and phospholipid metabolites containing arachidonic acid stimulate transepithelial sodium transport through amiloride sensitive channels and the action of these lipids involves the synthesis of prostaglandins. These lipids also inhibited the increase in water flow induced by ADH, and this effect was prevented with prostaglandin synthesis inhibitors. Prostaglandins alter intracellular calcium concentrations and agents effecting calcium metabolism alter cell surface morphology and the changes in surface substructure induced by ADH. These observations support the hypothesis that alterations in membrane permeability to water and ions may involve metabolism of membrane phospholipids and prostaglandin biosynthesis.

The purpose of this study is to show how television has affected the politics, education, economy, and religions of Nigeria. The background of each area is outlined to lay the groundwork for showing the influence of television on these aspects of the lives of Nigerians. A brief history of the development of radio and television in Nigeria is presented. Although government control of Nigerian television precludes unbiased political reporting, the medium has raised the consciousness and interest of Nigerians in political activities; education, however, is the area in which television proves its worth and potential. Under the direction of the government's unification goals, Nigerian television has been an informative, moderating, and conciliatory influence on the divisive elements in Nigeria.

This thesis concludes that (1) Immediately following the July Revolution, the Paris government refused to concede the right of search to British commanders. (2) Due to France's isolation in 1831-1833, she sought British support by negotiating the conventions of 1831 and 1833. (3) In response to Palmerston's insistence and to preserve France's influence Sdbastiani signed the protocol of a five-power accord to suppress the slave trade. Guizot accepted the Quintuple Treaty to facilitate an Anglo-French rapprochement. (4) Opposition encouraged by the Webster-Ashburton Treaty, however, forced Guizot to repudiate this new agreement. (5) As a concession to Guizot,Aberdeen dropped the demand for a mutual right of search and negotiated the Convention of 1845, establishing a system of joint-cruising.

Songs of Praise is a setting of four passages from the Psalms for soprano and chamber orchestra. The text is taken from Psalms 96, 114, 55, and 116 of the New American Standard Version, with each psalm scored as a separate movement. The duration of the work is approximately seventeen and one-half minutes. The instrumentation includes soprano, oboe, strings, and a percussion section of four players incorporating fourteen different instruments. The musical language employed is largely tonal, consisting generally of shifting tonal emphases achieved by exploiting the pitch relationships of traditional tonality. The movements are contrasting in character, according to the text, but generally of the same style. The vocal line predominates throughout spanning two octaves and a minor third from an A below middle C to a high C above the treble clef.

The purpose of this thesis has been to prepare a group interpretation script based on the National Aeronautics and Space Administration and its major manned programs. The script is designed to inform high school students and the general public of the space program. Available literature on oral interpretation and readers theatre have been investigated with particular attention given to the value of readers theatre as a means of instruction. Questionnaires were circulated among aerospace professors throughout the country and companies involved in the space industry. In their responses, aerospace company officials indicate strong support of this thesis and indicate a pressing need for such an informative script.

The purpose of this study was to examine the status and the content of the middle/junior high school art- programs in Texas. A questionnaire designed to elicit information concerning the art program was sent to middle/junior high school art teachers in Texas. The responses were analyzed according to the school district size, the grades comprising the school, and the school enrollment using simple descriptive statistics. This study revealed the following areas concerning the typical middle/junior high school art program in Texas: school district size, school enrollment, art enrollment, grades in school, types of art courses, teaching objectives and approaches, art budget, resource materials, and art equipment.

This study is an examination of the beast motif associated with Stephen Dedalus in Joyce's Ulysses. The motif has its origins in Joyce's earlier novel, A Portrait of the Artist as a Young Man. In Ulysses the beast motif is related to Stephen's feelings of guilt and remorse over his mother's death and includes characterizations of Stephen as a fox, a dog, a rat, and a vampire. The motif consistently carries a negative connotation. Several literary sources for the imagery of the beast motif are apparent in Ulysses, including two plays by John Webster, a poem by Matthew Prior, medieval bestiaries, and a traditional Irish folk riddle. The study of the continuity of the beast motif in Ulysses helps to explain the complex characterization of Stephen Dedalus.

A new procedure has been developed to concentrate the phosphofructokinase from muscle of Ascaris suum with minimum loss of activity. By utilizing this method, 50 ml fraction was concentrated to a final volume of 3 ml in about 1.5 h without loss in enzyme activity. The concentrated enzyme had a specific activity of 64 units per mg. Ascaris muscle-cuticle was incubated in 50 1M solutions of either acetylcholine, serotonin, y-aminobutyric acid, levamisole, or saline alone. Phosphate analysis of the isolated phosphofructokinase from each incubation revealed that the enzyme contained the following moles of phosphate per subunit: 2.9 (acetylcholine), 2.2 (serotonin), 2.0 (y-aminobutyric acid), 1.5 (levamisole), and 3.4 (salne alone). The present study did not establish a direct correlation between degree of phosphorylation and phosphofructokinase activity. Phosphofructokinase from muscle of Ascaris suum appears to contain several phosphorylation sites, and one of these sites is required to be phosphorylated in order for the enzyme to exhibit maximum activity under physiological conditions.

This study begins to fill the gap in sociological literature on movements and countermovements by exploring the dynamic environment of two movement organizations. After documenting the climate of public opinion on abortion, it investigates the strategy and tactics employed by a movement to maintain that opinion and a countermovement to reverse that opinion. It relates social movements to their social environments, social change, opposition, and strategy and tactics. It illustrates the efficacy of single-issue groups in the American social and political environment. Finally, this thesis demonstrates the validity of exploratory studies by uncovering elements of social movements and countermovements that had not been previously investigated.

This study tests the relationship between certain economic scenarios and the state of the economy in regard to inflation and recession. Using data gathered from government publications, the economy was divided into periods of inflation, recession, and recession recovery. These periods were regressed against variables representing four schools of economic thought: monetarist scenario, structural scenario, power scenario, and micro, or supply side scenario. This study concludes that because of the complex nature of the economy, all representative variables have both positive and negative effects on the economy and no one scenario holds the key to economic stability.

This study investigates the relationship between stagflation and price stability and full employment and four economic scenarios and the economic condition. The data used in the study were obtained from government publications and were analyzed using hierarchical multiple regression. The standard inferential apparatus were employed. Give independent variables were found to be significant in explaining the causes of stagflation. These were: absolute change in M1, oil embargo of 1974, corporate profits, output per hour, and Iranian crisis of 1979. In conclusion, the causes of economic instability do not rest with one single theory or factor, but a combination of several.

The entire ballet is approximately thirty-one and one-half minutes in duration.

The synthesis of mechanical/organic abstracted forms with suggestive power and specific purpose are elements i decided to continue to explore. I wished to make a more careful and systematic analysis of how something man-made could be transformed into a quasi-mechanical abstraction, perhaps a process similar to that in the Mayan art. The purpose of this project was: (1) to analyze how the shapes and forms arise in my abstract images and (2) to devise specific functions for them within the context of the final form.

This thesis relates a technique for increasing the optical strength of NaCl and KCl single-crystal samples. The 1.06-μm pulsed laser damage thresholds were increased by factors as large as 4.6 for a bulk NaCl single-crystal sample. The bulk laser damage breakdown threshold (LDBT) of the crystal was measured prior to and after heat treatment at 800*C using a Nd:YAG laser operating at 1.06 μm. Bulk and surface LDBTs were also studied on samples annealed at 400° C. These samples showed differences in damage morphology on both cleaved and polished surfaces, and the cleaved surfaces had improved damage thresholds. However, neither the polished surfaces nor the bulk showed improved threshold at the lower annealing temperature.

Unlicensed radio stations in 1933 tested the Radio Act of 1927 as to whether or not the Federal Radio Commission (FRC) had the right to regulate radio stations whose signals were allegedly intrastate. The FRC believed it could regulate such radio stations and proceeded to confiscate equipment, charge individuals with violation of the law, and bring them to trial, either in an injunction hearing, a criminal trial, or both. The most formidable case was that of United States v. Gregg et al. The challenge was met by the FRC and the judge, whose decision is still quoted in legal documents. The decision upheld the Radio Act of 1927 and the FRC's right to regulate all radio stations, licensed or unlicensed.

The decade of the 1850s saw the Texas press separate into two opposing groups on the issue of filibustering. The basis for this division was the personal beliefs of the editors regarding the role filibustering should have in society. Although a lust for wealth drove most filibusters, the press justified territorial expansion along altruistic lines. By 1858, however, a few newspapers discarded this argument and condemned filibusters as lawless bands of ruffians plundering peaceful neighbors. Throughout the decade, the papers gradually drifted from a consensus in 1850 to discord by the date of William Walker's third attempt on Nicaragua in 1858.

The purpose of this project is 1) to create a Thai character set for text processing, 2) to write a text processing program for the character set, and 3) to allow users to create and save the text.

The problem was to combine yarns and fabrics, through various textile processes, (off-loom and on-loom techniques may be incorporated), that involve a personal dimension and an aesthetic value. The specific questions to be examined were the following: 1. How are successful textural surfaces achieved? 2. What kinds of interdependence among color, surface texture, and imagery exist? 3. How foes scale affect the works? 4. In what ways are autobiographical images compatible with the processes?

I decided to simplify the composition of my work in subject matter, color, size and style without destroying its visual impact. Experimentation in surface quality gave variety to the simplified content. My main commitment to the accomplishment of this problem was to avoid complexity in any form. I wanted to give as much information as possible using minimal means.

Among the early applications of computers, one can find frequent mention of intelligent instructional systems. Such intelligent instructional systems represent a new generation of learner-based computer aided instruction, preceded in time by the original frame-based systems and an intervening generation of expert-based CAI. The history of CAI is characterized by three generations: Frame-based CAI, Expert-based CAI and Learner-based CAI.

This study analyzed The Children's Hour, The Little Foxes, Watch on the Rhine, Toys in the Attic in terms of the forms of human love delineated by Erich Fromm in The Art of Loving. The motives and actions of one or more principal characters and their dramatic situations were studied. It was discovered that, in the plays that were examined, each character responded to his or her situation in a loving or a hateful manner and that these choices with regard to love provided the dramatic matrix of the play.

The Raman linewidths of the carbon-halogen stretching mode was measured as a function of temperature in ethyl bromide, isopropyl chloride, isopropyl bromide, t-butyl chloride, t-butyl bromide, chlorobenzene, bromobenzene, iodobenzene and o-dichlorobenzene. The vibrational relaxation times showed a very clear trend. Together with earlier work on methyl iodide, these results provide evidence that the vibrational dephasing efficiencies (T^-1_iso) of the carbon-halogen mode vary in the order of Cl > Br > I. Vibrational dephasing times were calculated from the Fischer-Laubereau Isolated Binary Collision Mode. If further work shows this transferability to extend to other types of skeletal modes in molecular systems, this would have significant ramifications on future vibrational lineshape studies.

This composition is a single-movement work for three choirs and full orchestra, including celesta, piano, and four percussionists. Total duration is fifteen minutes. The music is divided into six sections, with the overall form being substantially influenced by the structure of the poem, War Is Kind, by Stephen Crane (1871-1900). Many devices are utilized to contrast tension and relaxation, as associated with ironic elements of the text, with repetition and development of musical elements and motives providing unity for the entire work.

The purpose of investigating the conflict over the Western Sahara is to trace and analyze its impact upon the political stability of the northwest region of the African continent. Chapter I provides background information on the Western Sahara. Chapter II discusses the international political developments affecting the Western Sahara. Chapter III discusses the positions of Morocco, the Polisario, Algeria, and Mauritania; Chapter IV analyzes those of Spain, France, the Soviet Union, and the United States. Chapter V describes the role of the OAU in dealing with the conflict. The internal economic development of the involved parties has been disrupted because they were obliged to appropriate funds to purchase arms for the exigencies of the war. Ending the conflict depends upon improving relations between Morocco and Algeria.
