Applications of CFD and visualization techniques

In this paper, three applications are presented to illustrate current techniques for flow calculation and visualization. The first two applications use a commercial computational fluid dynamics (CFD) code, FLUENT, performed on a Cray Y-MP. The results are animated with the aid of data visualization software, apE. The third application simulates a particulate deposition pattern using techniques inspired by developments in nonlinear dynamical systems. These computations were performed on personal computers

Molecular genetic studies of bacteroides fragilis

Bibliography : pages 234-264.Some genetic systems operative in Bacteroides fragilis have been successfully investigated. Firstly the bacteriocin produced by the B.fragilis BF-1 strain was purified and partially characterized. This bacteriocin was found to be cell bound and constitutively produced by the bacteria. The purified bacteriocin was a protein with an apparent Mr of 6400-7200, and was relatively heat stable. The action of the bacteriocin resulted in the lysis of sensitive bacteria. As previous reports indicated that a bacteriocin isolated from the BF-1 strain inhibited the action of RNA-polymerase in-vivo and in-vitro, RNA-polymerase was extracted and partially purified from the bacteriocin sensitive B.fragilis BF-2 strain (described in Appendix 5). This enzyme was essentially similar to that described for other Eubacteriales, but was not inhibited in the in vitro assay by the purified bacteriocin described in this thesis

Instructional Management: Assessment of Competencies of Secondary Health Occupations Teachers

Health occupations teachers are facing many challenges which necessitate development of new competencies in order to facilitate a viable Health Occupations Education program. An important teacher competency is instructional management which entails obtaining instructional resources; projecting resource needs; managing budgeting and reporting responsibilities; developing and maintaining a filing system; providing for student safety and first aid needs; assisting students in developing self-discipline; and planning, organizing, managing, and maintaining the physical facilities of the laboratory. To address these challenges, data were collected in Alabama concerning Health Occupations Education teachers’ perceptions of their educational needs relative to instructional management. Overall the majority of teachers rated their competence as above average in all areas of instructional management. The highest need was combatting problems of student chemical use. The highest competency rating was providing for student safety. Further research is recommended to monitor these competencies

Educational Needs and Interests: Perceptions of Secondary Health Occupations Education Teachers in Alabama

The perceived educational needs and interests of all 78 secondary health occupations teachers in Alabama were measured on the basis of 22 supplemented teacher competency topics from an earlier study at The Ohio State University. The data were statistically analyzed utilizing reliability, polychoric correlations, factor analyses yielding four factors, and general linear model procedures, and MANOVA models based on seven demographic independent variables. The results indicated multivariate significance for tenure, Master’s Degree in a field other than health occupations education, interest in health occupations education, and educational status. The teachers were concluded to have indicated an interest in several degree programs and to have perceived themselves competent in the majority of response areas; yet, wanted and needed continuing education workshops or course offerings to address their needs
