Lipids and Phospholipase Activity of Vibrio Cholerae

Lipids and Phospholipase Activity of Vibrio Cholerae

Date: August 1972
Creator: Brian, Buford Leo
Description: One purpose of this investigation is to determine the fatty acid and lipid content of typical Vibrio cholerae cells. The comparison of cholera lipid constituents with those of closely-related bacteria might be of taxonomic value. Furthermore, chemical characterization of the cholera vibrio could provide useful criteria for identification of these disease-producing microorganisms.

Lipodystrophy, Body Image and Depression in Hiv Positive Black Women

Lipodystrophy, Body Image and Depression in Hiv Positive Black Women

Date: May 2014
Creator: Carr, Jarice N.
Description: Human immunodeficiency virus (HIV) seropositive men on highly active antiretroviral therapy treatment (HAART) who experience lipodystrophy syndrome (LD), a side effect of HAART, rate themselves as more depressed than those who did not experience LD(Crane et al., 2008). Furthermore, men who rated their LD symptoms as more severe also scored higher on depression measures than men who experienced less severe symptoms. It is unknown these findings can be generalized to other groups of HIV positive individuals. The current study seeks to fill this gap in the literature by exploring the associations between LD, body image, and depressive symptoms in an archival sample of HIV positive Black women. This study aims to describe the body changes associated with HAART in a Black female sample and explore the relationships between LD, body image, depression, and quality of life. Findings supported past research indicating a correlation between depression and poor body image but did not indicate that body image quality of life moderated the relationship between perceived body changes and depression. Results expanded on the literature by indicating that perceived body changes may be more distressing to Black women with HIV than objective changes. Lastly, findings suggested that Black women may have inaccurate ...

Liquid Nitrogen Propulsion Systems for Automotive Applications: Calculation of Mechanical Efficiency of a Dual, Double-acting Piston Propulsion System

Liquid Nitrogen Propulsion Systems for Automotive Applications: Calculation of Mechanical Efficiency of a Dual, Double-acting Piston Propulsion System

Date: May 2008
Creator: North, Thomas B.
Description: A dual, double-acting propulsion system is analyzed to determine how efficiently it can convert the potential energy available from liquid nitrogen into useful work. The two double-acting pistons (high- and low-pressure) were analyzed by using a Matlab-Simulink computer simulation to determine their respective mechanical efficiencies. The flow circuit for the entire system was analyzed by using flow circuit analysis software to determine pressure losses throughout the system at the required mass flow rates. The results of the piston simulation indicate that the two pistons analyzed are very efficient at transferring energy into useful work. The flow circuit analysis shows that the system can adequately maintain the mass flow rate requirements of the pistons but also identifies components that have a significant impact on the performance of the system. The results of the analysis indicate that the nitrogen propulsion system meets the intended goals of its designers.

Listening to the Freshman Voice: First-year Self-efficacy and College Expectations Based on High School Types

Listening to the Freshman Voice: First-year Self-efficacy and College Expectations Based on High School Types

Date: May 2013
Creator: May, Paul B.
Description: This quantitative study used Astin's I-E-O theory to explore the relationship between a college freshman's high school background and academic self-efficacy. The Beginning College Survey of Student Engagement was used to measure academic self-efficacy across four types of high schools. Student gender and precollege experiences (dual-credit and communication assertiveness) were used as control. A total of 15,400 first-year students were included in this study. An ANOVA was used to examine the differences between groups, and ordinary least-square analysis was used to study the factors that affect academic self-efficacy. Results showed statistically significant difference in academic self-efficacy between public and private religious high school graduates. Specifically, graduates of public high schools had statistically higher academic self-efficacy than graduates of private religious high schools (p < .001). Additionally, females and participants of dual-credit courses also tended to have higher academic self-efficacy. Finally, analysis revealed that a first-year student's communication confidence is highly correlated to their academic self-efficacy. Results confirm in-coming first-year students perceive higher education engagement differently based on traits attributed to their precollege experiences. Results point to criteria colleges may be able to use in identifying freshmen at risk for low academic self-efficacy and, therefore, for problems in retention and degree ...

Literary and Realistic Influences upon the Women of the Spectator

Literary and Realistic Influences upon the Women of the Spectator

Date: August 1952
Creator: Perry, Carolyn Oliver
Description: This study will outline the two great literary genres of character-writing and satire, upon the tradition and practice of which Joseph Addison and Richard Steele based their characters of women in the Spectator. The three-fold purpose of this study is to determine how the Spectator was influenced by, and what it in turn contributed to, the two literary genres, the "Character" of women and satire on women; and to present the social status of the female audience as it existed and as the Spectator sought to improve it.

The Literary Criticism of H. L. Mencken

The Literary Criticism of H. L. Mencken

Date: December 1970
Creator: Sellers, Stephen W.
Description: The thesis of this paper is that Mencken was a better critic than he is credited with being, that he was unusually discerning in his judgment of the fiction of his time, and that his criteria are clearly stated in various of his writings. It is conceded, however, that his taste in poetry was limited and that his contribution to dramatic criticism was not? greatly significant.

Literature in the Age of Science: Technology and Scientists in the Mid-Twentieth Century Works of Isaac Asimov, John Barth, Arthur C. Clarke, Thomas Pynchon, and Kurt Vonnegut

Literature in the Age of Science: Technology and Scientists in the Mid-Twentieth Century Works of Isaac Asimov, John Barth, Arthur C. Clarke, Thomas Pynchon, and Kurt Vonnegut

Date: August 2010
Creator: Simes, Peter A.
Description: This study explores the depictions of technology and scientists in the literature of five writers during the 1960s. Scientists and technology associated with nuclear, computer, and space science are examined, focusing on their respective treatments by the following writers: John Barth, Kurt Vonnegut, Thomas Pynchon, Isaac Asimov, and Arthur C. Clarke. Despite the close connections between the abovementioned sciences, space science is largely spared from negative critiques during the sixties. Through an analysis of Barth's Giles Goat-boy, Vonnegut's Cat's Cradle, Pynchon's The Crying of Lot 49, Asimov's short stories "Key Item," "The Last Question," "The Machine That Won the War," "My Son, the Physicist," and Clarke's 2001: A Space Odyssey, it is argued that altruistic goals of space science during the 1960s protect it from the satirical treatments that surround the other sciences.
