This investigation concerned determining certain factors which affect the activity of cyclopropane synthetase in L. plantarum. In vitro experiments showed the enzme to be sensitive to ionic strength and subject to product inhibition by S-adenosylhomocysteine nucleusidase, which relieves this inhibition by degrading SAH to adenine and ribosylhomocysteine.

This study examines the α-adrenergic constrictor tone varies with intensity of exercise, the effects of coronary α1-adrenergic blockade on left ventricular contractile function and regional myocardial perfusion, and compares the effects of increasing coronary blood flow by removing α1-constrictor tone.

The purposes of this study were to examine the occupational goals of women in banking, manufacturing, and education; to examine women's awareness of their own potential; to compare the attitudes of working women toward themselves; to compare the attitudes, self-concepts, and career achievement between females aged twenty-five to thirty-five and females aged forty to fifty; and to compare the attitudes, self-concepts, and career achievement of females in banking, manufacturing, and education.

This study was a descriptive analysis of the orientation program for a large junior college in the Dallas/Fort Worth Metroplex. Its purposes were (1) to describe the freshman orientation course, (2) to analyze data compiled from rating forms which recorded student perceptions of each aspect of the course, and (3) to discuss the implications of the data for junior college student service personnel as they attempt to establish programs that will effectively aid students in making a successful adjustment to college.

The problem of this study was an investigation of teacher and administrator perceptions of teacher evaluation and the relationship of those perceptions to teacher evaluation policies and practices in public high schools in the State of Texas.

A mating between Escherichia coli 4318 (thi-leu-Las-Hfr) and E. coli A-1 (Met-Las+ F-) resulted in the formation of phototrophic recombinantshaving L-asparaginase activities at three distinct levels. The physiology of L-asparaginase synthesis in these recombinants is described.

The purpose of this study is to develop a prototype instrument that may be used in conjunction with the Texas Teacher Appraisal System instrument to appraise the competencies expected of school library media specialists.

The purpose of this study is to trace the development of a comparatively young orchestral instrument, the bass clarinet, and its use in the symphony orchestra. The first chapter concerns the development of the bass clarinet from the earliest imperfect specimen to the modern day instrument. The second chapter discusses physical characteristics that are peculiar to the bass clarinet. The third chapter deals with the particular methods of using the bass clarinet in orchestral literature by various composers, from its introduction into the orchestra by Meyerbeer through the present.

The earthworms, Lubricus terrestris and Eisenia foetida, were used as non mammalian surrogate models to assess the immunotoxicpotential of xenobiotic to mammals. Assays were developed and optimized for detecting spreading activity and phagocytosis of rabbit red blood cell (RRBC), bacteria, and yeasts by macrophage-like coelomocytes of L. terrestris.

This study addresses the question of cross-country standardization of advertising by identifying existing cross-national differences in magazine advertisements. A content analysis of 1,983 advertisements in business, women's and general interest magazines was performed. The sample included 1989 and 1990 magazine issues from the United States, United Kingdom, France, India and South Korea.

This study investigated the relationship between visual cues in art reproductions, simple linguistic time vocabulary and children's temporal understandings. During interview sessions, 33 third-grade students attending two suburban schools were asked to place three art postcard reproductions sets in chronological order. Interviews were recorded, transcribed, and coded for analysis. Linguistic references used to represent historical time and visual cues within the art postcards which caused students to place art works in a particular time sequence were documented.

Efforts were made to (1) enumerate and isolate the intestinal bacteria of Ascaris suum; (2) identify those bacteria isolated; and (3) assess the ability of intestinal bacteria to produce serotonin.

The objective of the completed research was to characterize the morphology of individual neurons within monolayer networks of fetal mouse spinal tissue via intraperikaryal injections of horseradish peroxidase (HRP). Thirty labelled neurons were reconstructed via camera lucida drawings and morphometrically analyzed.

The problem of this study is to educe and examine philosophical ideas embedded in major models of teacher evaluation. This study is qualitative, involving the presentation and analysis of ideas which affect educational practice.

The effects of hypothermia on cultured mammalian (mouse) spinal cord neurons which had been subjected to a defined physical trauma (amputation of a primary dendrite 100μM from the perikaryon) were investigated.

The studies reported in this dissertation constitute the first evidence that methylprednisolone (MP) has been shown to ameliorate specific components of secondary trauma including ischemia, lactic acidosis, and lipid peroxidation.

Polyacrymalide gel isoelectric focusing (PAGIF) in thin-layer was used to resolve proteins of Mycoplasma spp., Acholeplasma spp. and of eight strains of Ureaplasma urealyticum (T-Strain). A mixture of urea, Triton X-100, and dithioerythritol was used to solubilize sonically disrupted cells.

The problem considered was that many direct sales personnel do not recruit others into the sales force even though monetary rewards and recognition for achievement can be earned for successful recruitment. The purpose of this study was to identify attitudes that were characteristic of consultants who were successful recruiters within a direct sales organization.

This research effort focused on developing a process model to include art in the individualized education programs (IEPs) of physically handicapped and health impaired students which followed guidelines prescribed by Public Law 94-142. A systems approach was utilized for the development of the model. The sequence of interrelated tasks involved stating needs, identifying the problem, assessing the resources, identifying the population sample, establishing definitions of disabilities, specifying objectives, defining methodologies, developing a programmatic plan, conducting the operational phase, evaluating and refining the model.

The goal of this work reported here is to test the limits of the ECPSSR theory in the transition region of the low Z1/Z2.

The problem addressed in this paper was the appropriateness of fiber, especially in the form of fabric, as an art medium. Relevant statements by crafts makers, philosophers, art critics, and artists were investigated along with historical and contemporary art and craft works.

Four site-specific works produced between 1982 and 1984 in which Hans Haacke utilized the traditional medium of oil on canvas were examined in conjunction with an overview of the underlying and interrelated principles and concepts that have guided his approach to art from 1958-1988.

This study is about the development of a curriculum guide which projects flexibility, continuity, sequential framework, and to a certain extent, uniformity, around which each teacher may build an art program that will best meet the students' needs. Areas pertinent to developing the curriculum guide are presented in light of literature in this field. The guide may be used to facilitate the teaching of art in recognizing and understanding artistic development that is essential in bringing to fruition the inherent individual ability of all the Junior High Catholic School students.
