The purpose of this problem was to investigate the advantages and limitations in the use of blacksmithing techniques combined with the construction techniques of arc welding and the use of power tools to construct large outdoor sculpture. Specific questions will be asked to determine the suitability of this method of working. The questions are: 1. Can blacksmithing techniques be used in the construction of large outdoor sculpture? a. what specific techniques are appropriate? b. Will some techniques be used more than others? 2. Will these techniques be used more than others? 2. Will these techniques take an inordinate amount of time and make them impractical for the artist to use?

Our problem was to produce art in a collaborative manner. Due to the nature of our problem, we proposed to explore specific aspects of collaborative art and answer these questions: 1. in what ways is the co-artist's input beneficial? 2. How are the artist's skills broadened by working with a fellow artist? 3. What is involved in developing a professional working relationship between male and female artist? 4. What understanding of differences in working styles is acquired? 5. What are the differences reflected in each artist's earlier works as compared to the collaborative pieces?

This study involves investigating the combination of delicately cast forms, domed shapes and forged silver into an aesthetic form of jewelry. The specific questions considered were as follows: 1) can the sequential interplay of forms be interrelated from initiation to completion of the study? 2) Can the techniques contrast with one another? 3) Can the scale of the forms be varied? 4) Can the three techniques of construction create body adornment? 5) Can these forms individually or in a combined grouping make a personal statement?

This project was an investigation into the specific influences upon my art produced by my living in Riyadh, Saudi Arabia for two years from August 1976 through August 1978. Initially, I had to make a major psychological and environmental adjustment. This period of adjustment, referred to as culture shock, was a time of personal confusion about the differences between the American and the Arabian cultures. I characterized my state of mind during this period as a psychological numbness and confusion. This adjustment period altered my interests so that the drawings I had done before I left the United States no longer held their original significance and new interests began to appear. I hope to identify some of the changes that occurred by examining and comparing my earlier drawings with those completed since my return.

This interface was bought to perform floating-point arithmetic and for its function capabilities such as SIN, COS, and e^x. My application required an integer truncation function that is not performed by this calculator, so i wrote a small assembly language subroutine to do it. A potentially irritating problem is that the calculator chip does not automatically convert to scientific notation if the numbers become too big to display in floating point. The control program must keep track of the display mode.

Hematocrit, serum-iron and iron-binding capacity were used to test the iron status of a sample of fifty-six volunteer students. Subjects completed a questionnaire to examine whether a correlation exists between iron status and iron knowledge. The sample, including 20 males and 36 females, consisted of ten nutrition majors , eight biology majors, thirty-eight other majors, and eight vegetarians. The four measures revealed that a high prevalence of iron deficiency did not exist in this student population. Other findings: sex and iron status are not related; no correlation exists between iron knowledge and iron status; and vegetarians have an iron status comparable to that of non-vegetarians.

The primary purpose of this study is to give simple and detailed instructions for building a log cabin by the post-and-beam method. The data were gathered from three sources: (1) library research, (2) interviews with experienced builders of cabins, and (3) personal experience in cabin construction. A step-by-step guide for building a cabin is given in Chapters II and III, which explain in depth how to construct each section of the cabin, from laying the foundation to putting on the finishing touches. It is believed that any serious builder can follow the directions and construct his own log cabin for less than one-third the cost of a similar commercially built cabin.

This investigation was based on a production performed by the Irving, Texas, Community Theatre in March, 1978, directed by the author of this thesis. The paper concerned the problems of producing a play under adverse conditions, such as lack of money, inadequate technical equipment, and a small stage. Chapter I included an investigation of the reviews of the original production in order to establish criteria by which to judge the Irving production. Chapters II and III dealth with varied technical aspects and their application under the adverse conditions. Examples of the technical factors were included in Chapter IV, with a scene synopsis. Chapter V contained a primarily favorable analysis based on the critic's and the audience's judgments, indicating most production elements to be successful.

This study investigated the clothing preferences of large-size women who shopped in selected large-size specialty stores in North Dallas. Questions were asked regarding the respondents' age, employment, income, dress size and degree of fashion-consciousness. Also investigated were preferences regarding apparel and shopping sources. A questionnaire was used to obtain the desired information. Based on the data obtained, it was found that large-size women have certain preferences concerning the clothing they purchase and the sources they shop.

The Cardiac Profile, a pattern of serum enzyme changes seen within seventy-two hours after an AMI, is diagnostic aid for detecting occurrence of infarcts. The effects of exercise stress on the Cardiac Profile aid clinicians in avoiding diagnostic errors in patients immediately after exercise. Five male volunteers ran from six to ten miles. Serum enzyme levels were monitored serially three days before and five days after stress. Enzyme activity was determined spectrophotometrically and electrophoretically. Significant increases in total CPK and LDH were seen. An LDH 'one-two flip' occurred eight hours after exercise. No MB-CPK was found following the run.

This study investigated leisure interests and leisure participation of executives in the Dallas-Fort Worth Metroplex. The Leisure Activities Blank and a questionnaire designed to collect demographic information were administered to twenty-five randomly selected executives. Five hypotheses were tested. Four were retained; one was rejected. Gold was found to be the favorite leisure interest of the respondents. They are currently engaged in eighteen leisure interests, and indicated a desire to participate in thirty-six leisure activities at some future time. Leisure interests which the respondents participated in during their past, or are currently engaged in, appear to be those they hope to continue in the future.

This study was designed to test whether Japanese natives who retained traditional Japanese value orientations and who resided in the Dallas, Texas area would have unfavorable attitude toward the concept of comparative television advertising. Data were collected from 104 respondents of varying sex, age, education, occupation, length of stay in the United Sates, intention of settling in the United States, and television viewing horse. All null hypotheses were accepted, indicting that cultural influence among Japanese natives in the Dallas area did not result fin unfavorable attitude toward comparative advertising despite the fact that in Japan, the name of names in advertising is counter to basic Japanese culture and tradition.

The document consists of a commentary on the historical background of the work and an edition of the restored score. The commentary treats its relationship to the ballad opera, sources and alternate settings of the music and libretto, a history of the development of "Hail to the Chief," biographical sketches of the primary composers, and a section on early productions in England and America. The commentary includes a history of the English and American premieres, lengths of the first-runs, and the names of the theatres in which the performances were mounted. The reconstructed score is a piano-vocal performance edition with dialogue, cues, scenery, costume and property plots indicated in detail.

Thirty-one rats were trained on a differential reinforcement of low rate schedule. After responding had stabilized, animals were injected with methylphenidate, twice weekly, presession. Methylphenidate produced dose-dependent increases in response rates and decreases in reinforcements. Repetition of these doses produced a reduced drug effect, and a third administration of the 10 mg/kg dose further reduced the drug effect. Subsequently, the effects of daily and intermittent administration were determined for this dose. Daily methylphenidate, pre-session, produced tolerance to the behavioral effects of methylphenidate and cross-tolerance to the amphetamines. Twice-weekly methylphenidate, pre-session, produced partial tolerance to methylphenidate and partial cross-tolerance to the amphetamines. Thus, periodic exposure to the behaviorally disruptive effects of a drug of the amphetamine class reduces the effects of subsequent exposure.

Early function of a temperature-sensitive mutant of staphylophage 44A HJD was examined during the twenty-five-minute period following infection. Host cell and phage DNA were labeled with C and3H respectively. DNA was separated into linear and covalently closed circular (CCC) forms by density-gradient centrifugation. The host, S. aureus, shows no CCC DNA, and apparently carries no plasmid. Following infection with wild type phage, CCC DNA forms occur in tritiated and 1 C DNA fractions 10 to 15 min after infection. Infection with mutant at permissive temperature also demonstrates CCC DNA with both labels. Infection with mutant at nonpermissive temperature produced no CCC DNA during the first 25 min after infection. The impaired function in this mutant may be a linker protein.

A method for purification and radiolabelling phosphoglucose isomerase was devised in order to develop a sensitive quantitative radioimmunoassay for the detection of the enzyme irrespective of its catalytic activity. For four genetic variants of PGI no difference in the molecular specific activity was observed. In one variant (PGI-Denton), liver and heart tissue extracts, and in mature erythrocytes (as compared to normal erythrocytes), a decreased molecular specific activity was observed which initially may imply that these samples contain cross-reactive material which is not catalytically active.

The purpose of this study was to investigate adolescent knowledge of physical, mental, social, and emotional development of babies and young children. The study was concerned with the effects of the following factors on adolescent knowledge of child development; geographic location, family size, ordinal position, and years of homemaking classes in school. Questionnaires were administered to 200 homemaking students in high schools in Parker and Tarrant counties. The only factor significant at the .05 level in affecting.adolescent knowledge was geographic location. Students from rural high schools obtained higher overall child development knowledge scores than students from urban high schools. Further research to compare the knowledge of students not enrolled in homemaking classes to the knowledge of students enrolled in homemaking classes is recommended.

The purpose of this study was to determine (1) the size of the Saudi Arabian manpower shortage in light of the Second Development Plan, (2) the number of skilled and semi-skilled workers that will be graduated from vocational and technical programs during the plan period, and (3) the factors that explain the major causes of the labor shortage problem. In order to accomplish these objectives, the study has considered two questions: (1) Is there a consistency between the manpower needs of skilled and semi-skilled workers and the vocational and technical training programs' output? (2) What are the major factors that explain the labor shortage in Saudi Arabia?

This study is concerned with the regulation of Lasparaginase (LA) in the cell-free crude extracts from Lactobacillus plantarum (ATCC8014). A previously reported finding that adenosine triphosphate (ATP) inhibits the action of LA in crude extracts was confirmed. The study was extended to include the mono-, di-, and triphosphates of adenosine, guanosine, cytidine, and uridine. These compounds were also shown to inhibit LA activity. These andother studies revealed that LA appears to be an allosteric type enzyme exhibiting positive homotropism with respect to substrate and heterotropism with respect to the nucleotides tested. The regulation of LA activity by high energy compounds, when coupled with asparagine synthetaseL suggests a relationship between amide synthesis-amide degradation and the energy levels of the cell.

This study of semigroups discusses groups, ideals, relations on semigroups, and relation classes in semigroups. Each topic is covered in some detail; but since this is a general study of semigroups, no topic dominates the paper. The definitions, theorems, and corollaries are supplied by Dr. August Lau, and all proofs are the work of Ms. Bryant.

Effects of selection risk on sex discrimination in hiring were investigated. Ninety-six male and female educational administration graduate students rated ficticious resumes on suitability for hiring for the female-oriented position of secondary school teacher. Sex and selection risk level were varied, with sex of rater as an assigned factor. Analysis of variance yielded significant main effects for sex (p < .01) and selection risk level (p < .05). All ratings were lower in high selection-risk situations, with males preferred over females across both levels of risk. Results suggested that ratings were based on a stereotype of female inferiority in work efficiency, overriding job sex-orientation as a decision factor.

The purpose of the study was to compare the attitudes of 4-H youths and their parents concerning 4-H competitiveness. The sample was composed of seventy-nine 4-H youths and their parents from three North Texas Counties. The instruments, which consisted of an "Opinionnaire for Parents" and an "Opinionnaire for 4-H'ers," were designed to obtain the 4-H'ers' and parents' attitudes about 4-H competition. The study revealed no significant difference in competitive attitudes between 4-H youths' and their parents' or between younger and older 4-H'ers. 4-H boys were found to have more competitive attitudes than 4-H girls. No significant relationship was found between parents' level of competitiveness and length of 4-H service.

The AKR strain of mice have a genetic trait for spontaneous development of lymphocytic leukemia. In this study, leukemic mice were found to have significantly larger (p<0.01) thymuses and spleens than preleukemic mice. The enlarged leukemic tissues were densely packed with a light staining cell, with a hollow-appearing nucleus. Tissues from preleukemic mice were observed to be infiltrated with a smaller, darker-staining lymphocyte. Fluorescent antibody staining was done on preleukemic and leukemic tissues, using three antisera against murine lymphocyte theta antigen, and an antiserum against murine IgG. Significantly brighter fluorescence, (p <0.05) with theta-specific antisera, was found in leukemic thymuses,spleens, and kidneys than in the same preleukemic tissues. Leukemic tissues had significantly brighter fluorescence (p <0.05) than preleukemic tissues with IgG antiserum.

This thesis looks at child development based on membership in 4-H clubs.
