Isolation of a  Pseudomonas aeruginosa Aspartate Transcarbamoylase Mutant and the Investigation of Its Growth Characteristics, Pyrimidine Biosynthetic Enzyme Activities, and Virulence Factor Production

Isolation of a Pseudomonas aeruginosa Aspartate Transcarbamoylase Mutant and the Investigation of Its Growth Characteristics, Pyrimidine Biosynthetic Enzyme Activities, and Virulence Factor Production

Date: December 2004
Creator: Hammerstein, Heidi Carol
Description: The pyrimidine biosynthetic pathway is an essential pathway for most organisms. Previous research on the pyrimidine pathway in Pseudomonas aeruginosa (PAO1) has shown that a block in the third step of the pathway resulted in both a requirement for exogenous pyrimidines and decreased ability to produce virulence factors. In this work an organism with a mutation in the second step of the pathway, aspartate transcarbamoylase (ATCase), was created. Assays for pyrimidine intermediates, and virulence factors were performed. Results showed that the production of pigments, haemolysin, and rhamnolipids were significantly decreased from PAO1. Elastase and casein protease production were also moderately decreased. In the Caenorhabditis elegans infection model the nematodes fed the ATCase mutant had increased mortality, as compared to nematodes fed wild type bacteria. These findings lend support to the hypothesis that changes in the pyrimidine biosynthetic pathway contribute to the organism's ability to effect pathogenicity.

The Isolation of GATB Aptitude Patterns for Six Major Fields of Study

The Isolation of GATB Aptitude Patterns for Six Major Fields of Study

Date: August 1965
Creator: Cullum, Felder Wilson
Description: The problem of this study was to isolate General Aptitude Test Battery patterns for persons who have succeeded in certain major fields of study at North Texas State University, Denton, Texas. In addition to the basic problem stated above, an effort was made to (1) determine the significance of the relationships between GATB scores and grade-point averages for all undergraduate courses taken; (2) determine the relationships between GATB scores and grade-point averages for all undergraduate courses in the major field of study, and (3) conduct a survey of all subjects selected for this study to determine their past, present and expected future fields of occupational endeavor since graduation from college and the relationship between such employment and the individual's major field of study in college.

Israel Zangwill as an Apologist

Israel Zangwill as an Apologist

Date: August 1967
Creator: Richman, Harvey A.
Description: Israel Zangwill, novelist, playwright, poet, and essayist, can be understood and appreciated best as an apologist whose chosen mission was to introduce the Jew to the English-speaking reader, a reader who had often see the word Jew on the pages of his literature but seldom had been able to meed an authentic specimen of the group in--or out--of print. This thesis will describe the works of Zangwill from an apologetic standpoint.

The Issue with Latino Voter Turnout: How Does the Issue of Immigration Affect Latino Voter Turnout?

The Issue with Latino Voter Turnout: How Does the Issue of Immigration Affect Latino Voter Turnout?

Date: August 2013
Creator: Robert, John M.
Description: In this study, I investigate how the issue of immigration affects Latino voter turnout. I hypothesize that U.S. Latino citizens who view immigration as highly important and helpful to the United States will be more likely to turn out to vote in midterm and presidential elections. In addition to a contextual analysis on elections in Arizona and California, I perform a probit regression analysis on survey data from Pew Hispanic's 2004 National Survey of Latinos on Politics and Civic Participation. The results are mixed with respect to the initial expectations. While respondents who view immigration as important and helpful are more likely to turn out than those who view immigration as important and hurtful, the results suggest that respondents who find immigration as unimportant may not be less likely to turn out. Further, there are some differences between Latino subgroups, although these differences are minor. Ultimately, the hypotheses presented in this study find moderate support.

Issues for the Nineties: An Analysis of 14 State Master Plans for Higher Education

Issues for the Nineties: An Analysis of 14 State Master Plans for Higher Education

Date: August 1994
Creator: Thompson, John Paul, 1947-
Description: The purposes of this study are (1) to identify the major policy issues being addressed by state agencies responsible for coordinating and regulating higher education; (2) to develop a classification system through inductive "clustering" that will aid in the analysis and synthesis of the major policy issues facing state coordinating boards for higher education; (3) to classify these policy issues; (4) to compare the goals and strategies of the various states; (5) to propose a list of significant policy issues that institutions and state agencies of higher education may face through the 1990s and into the 21st century.

Issues of Interpersonal Bonds

Issues of Interpersonal Bonds

Access: Use of this item is restricted to the UNT Community.
Date: May 2002
Creator: Morin, Tesa B.
Description: In this work, sections of bodies are joined with sections of other people's bodies in order to form a new whole. Adding or subtracting relationships can many times be uncomfortable and strange, which I depict in my invented individuals based on the phases of family, such as birth, death, marriage, divorce, and the acquisition of new forms of family. This work questions issues of the family in terms of its definition, whether biologically or culturally constructed. I am creating hybrids by separating body parts from the whole and then recombining them to form a new individual. These images are a result of thinking about the possibilities and changes that people go through as a result of the new growth or loss of relationships. This work is intended to bring awareness to the way in which people relate and families become more blended.

istance-Mediated Christian Higher Education: Student Perceptions of the Facilitative Nature of Selected Instructional Development Factors

istance-Mediated Christian Higher Education: Student Perceptions of the Facilitative Nature of Selected Instructional Development Factors

Date: May 2001
Creator: Nill, John G.
Description: A national survey was conducted to assess student perceptions of the helpfulness of specific instructional development factors in a distance education print-based program. Participants were all students who had successfully completed at least one distance education correspondence course with Global University or were currently enrolled in their first course. Instructional development factors studied included lesson openers, lesson outlines, lesson artwork, written objectives, amount of information presented before a study question is asked, typographical features, graphic art, study questions, answers to study questions, self tests, and unit progress evaluations. Basic demographic information was collected and survey respondents located their perceptions of instructional development factor helpfulness both on a Likert scale and on a rank-order scale. Respondents also were asked for comments on the instructional development factors studied. Differences among respondent groups were examined. Major findings include a tiered ranking by all groups showing formative evaluation factors to be the most helpful, content organization and presentation factors next most helpful, and visual enhancement features (graphic art, typographical design) the least helpful. Overall, perceptions of the facilitative nature of the instructional development factors were similar among most groups. Older students seem to focus more on organization while younger students exhibit a balance between ...
