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.

A sodium fusion-Ion chromatographic method for determination of fluorine, chlorine, bromine, and iodine in organic compounds is described. Seventeen organic halogen compounds and eleven mixtures were decomposed by Na fumes at 280-290°C for one hour or longer. The absorbing solutions were injected for ion chromatographic analysis using electrochemical and conductometric detectors. The arrangement of the apparatus includes the placement of the electrochemical and conductometric detectors. This method provides a mechanism providing for complete analysis for all four halogens in one ion chromatographic sample injection. Reproducibility is excellent and liquid sample handling is mentioned.

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 purpose of this research is to investigate the changes in countries of origin and occupational groups of immigrants to the United States after the implementation of the 1965 Immigration Act. The basic policy change in the 1965 Immigration Act was essentially the abolition of the National Origins Quota System. The new law led to obvious changes in the origins of immigrants. The number of Southern European, Asian and Caribbean immigrants significantly increased since the implementation of the Act. The sources of the various occupational groups shifted to some extent. The number of immigrants in the professional and highly skilled categories increased significantly. The impact of the changes aggravated the "brain drain" problem.

The overt teaching of the Monitor, or conscious rule awareness, to native Spanish-speaking ESL students was examined to note possible benefits to the students' oral English production. Native Spanish-speaking students of English (the experimental group) were taught an awareness of their ability to self-correct their spoken English. They were then compared to another group of native Spanish-speaking ESL students (the control group) in four areas: Ilyin Oral Interview score, total words produced, errors produced, and interference errors produced. The results of the study lend support to the theory that overt Monitor teaching could be beneficial to native Spanish-speaking students of English. The experimental group showed a significant gain in Ilyin scores and a significant reduction in the number of errors produced.

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.

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.

Cue-controlled relaxation is looked at to determine whether a component is efficacious as the entire procedure. Subjects were 40 male and 40 female undergraduates. Subjects were randomly assigned to one of four conditions: cue-controlled relaxation, progressive muscle relaxation, breathing exercises with a paired. cue word, on a presentation of the cue word without being paired. It was hypothesized that cue-controlled relaxation would be superior to a component of cue-controlled relaxation. It was determined that cue-controlled relaxation is not more efficacious than a particular component. Data suggests the majority of anxiety reduction takes place when the treatment focuses on the same modality from which the subject receives the most information about their anxiety. Implications and suggestions for further research are presented.

Acute effects of repeated sprinting upon serum creatine kinase (CK), lactic dehydrogenase (LDH), and isozymal activities were studied in five collegiate runners (R_s) and six non-runners (NR_s ). After an intermittent running treadmill test, blood sampling showed three-fold mean increases in CK with no change in LDH in both groups; group differences were insignificant (p>.05). Results suggest (1) intense anaerobic exercise produces moderate enzyme elevations; (2) relatively equivalent exercise intensities are critical to enzyme responses in exercising individuals of varying fitness levels; and (3) exercise-induced enzyme release may be consequential to muscle cell membrane permeability changes from decreased intracellular high-energy phosphates.

The basis of this investigation is to characterize growth property differences in normal versus virally transformed cells. Using a temperature-sensitive mutant of Rous sarcoma virus, the cells' transformation state is regulated by the growth temperature; at 33°C the cells are transformed, while at 39°C the cells have normal characteristics. The morphology of NRK cells is elongated and fibroblastic; when transformed the cells are rounded. Normal cells grow to a monolayer and stop, while transformed cells grow to saturation densities greater than just a monolayer amount. Transformed cells can form foci when grown in mixture with normal cells. Normal cells must be in contact with the culture vessel in order to grow, but transformed cells lack anchorage dependence for growth.

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.

In this thesis, we describe Schensted's algorithm for finding the length of a longest increasing subsequence of a finite sequence. Schensted's algorithm also constructs a bijection between permutations of the first N natural numbers and standard bitableaux of size N. We also describe the Hillman-Grassl algorithm which constructs a bijection between reverse plane partitions and the solutions in natural numbers of a linear equation involving hook lengths. Pascal programs and sample output for both algorithms appear in the appendix. In addition, we describe the operations on standard bitableaux corresponding to the operations of inverting and reversing permutations. Finally, we show that these operations generate the dihedral group D_4

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.

The purpose of this paper is to examine certain questions concerning infinite series. The first chapter introduces several basic definitions and theorems from calculus. In particular, this chapter contains the proofs for various convergence tests for series of real numbers. The second chapter deals primarily with the equivalence of absolute convergence, unconditional convergence, bounded multiplier convergence, and c0 multiplier convergence for series of real numbers. Also included in this chapter is a proof that an unconditionally convergent series may be rearranged so that it converges to any real number desired. The third chapter contains a proof of the Silverman-Toeplitz Theorem together with several applications.

This thesis describes a software implementation of the IEEE Floating-Point Standard (IEEE Task P754), which is believed to be an effective system for reliable, accurate computer arithmetic. The standard is implemented as a set of procedures written in Motorola 6809 assembly language. Source listings of the procedures are contained in appendices.

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 feeding ecologies of leaf pack-associated systellognathan stoneflies were examined from 6 June 1980 21 May 1981. Species composition, seasonal abundance, nymphal growth, feeding habits and mouthpart morphology were determined for the eight dominant stonefly species. Prey preferences and predator-prey size relationships were also examined for omnivorous and carnivorous species. Foregut analysis from 2860 individuals indicated opportunistic feeding on the most abundant prey insects, usually in proportion to prey frequency. Feeding preference studies generally indicated random feeding on major prey groups. Prey and predator sizes were usually highly correlated (p<0.01), with predators expanding their prey size thresholds with growth. The potential for competition between sympatric stoneflies for prey is discussed.

The music consists of an overture lasting approximately three and one-half minutes, and three scenes lasting approximately eight and one-half, nine and one-half, and ten minutes respectively. The entire ballet is approximately thirty-one and one-half minutes in duration.

For many years, educators and psychologists have attempted to define the strength of the relationship between self-concept and school performance., A productive approach may be to investigate academic self-efficacy. In the present study, data were collected for students at an alternative high school on the Measure of Academic Self-Efficacy (MASE), Intellectual Achievement Responsibility Questionnaire (IAR), number of weeks spent in the program, and various descriptive and behavioral measures. Correlations were computed to attempt to demonstrate that participation in an alternative program analogous to participant modeling is associated with increases in academic self-efficacy and internal attributions for educational events, and that these gains are associated with improved academic outcomes.

The theology of John Calvin, while not differing primarily in substance from traditional Reformation thought, was revolutionary in its impact on the cultural life of the believer. For Calvin, Christ was the Cosmic Redeemer through whom all of life was effected. Nothing in the life of the believer therefore was secular. Society, as a whole, was but a reflection of the grace of God and hence was an arena of concern for all people. Consequently, Calvin, the man, and Calvinists, later took an active role in the temporal life of man, concerning themselves with the governing of the state as well as the church, and the propagation of the arts and sciences.

A comparison of contingent word and phonics drilling exercises on oral reading errors was made and the effects of a work skipping contingency on reading comprehension were examined. Five learning disabled elementary school children served as subjects. Reading comprehension increased from 30 to 50% over baseline, while subjects progressed an average of two years through a reading series. Subjects responded differentially to the two drills on oral reading errors, but the combined effects of the drills produced a 50% average reduction in errors. Pre- and post-tests of reading achievement showed increases in reading grade levels ranging from .8 to 1.5 years during the 10 week, 30 session study. Results supported the efficacy of a behavioral approach to reading remediation.

The primary purpose of this study is to determine whether there has been a change in attitude of newspaper editors toward privacy matters. The study examines a 1976 survey of editors on some specific situations involving privacy and compares that survey with one done for this paper in the spring of 1983. The study also seeks to determine whether such factors as circulation size, type of readership and political philosophy have any influence on privacy decisions made by editors. The study shows that there has been a change in attitudes. A chi square test showed that the comparison of the two surveys was significant at .01. Figures gathered to determine influences on privacy decisions were scattered among many categories and too small to be statistically significant.

This investigation surveys pertinent literature, from 1917 to 1982 inclusive, regarding artistic vibrato and tremolo in singing. The contents are subdivided into individual investigative reports by various vocal researchers. Due to mounting confusion within the amassed literature, the need for systematic organization and evaluation is evident. Misunderstandings within the context of the literature and misnomers within the terminology require clarification and resolution. The evaluation intends to produce a proper perspective on vibrato and tremolo, eradicating some of the confusion surrounding the terms. Artistic vibrato is recognized as a desirable component in Western vocal music. In contrast, tremolo is deemed a deviant vibrato, i.e., a vibrato which deviates from artistic norms. The study attempts to clarify the distinguishing traits of these two vocal phenomena.

The Piers-Harris Self-Concept Scale for Children, the Florida Key: A Scale to Inter Learner Self-Concept, and the Walker Problem Behavior Identification Checklist were used to assess the self-concepts of 18 ambulatory physically handicapped children between the ages of 6 and 12 years. Data were analysed via one-sample t-tests. The hypothesis that mainstreamed handicapped children would exhibit somewhat lower self-concept than their nonhandicapped peers was not supported. In fact, some mainstreamed physically handicapped children may indeed exhibit higher frequencies of relating to peers and teachers, less acting-out behavior (among males), and better overall self-concept than the nonhandicapped populations from which the normative data were obtained (p < .05). These results were discussed in terms of the children's experiences within the hospital environment from which they were selected.
