Multiple sets of chemotaxis genes including three cheA homologs were identified in the genome sequence of the anaerobic bacterium Desulfovibrio vulgaris Hildenborough. Each CheA is a histidine kinase (HK) and part of a two component signal transduction system. Knock out mutants in the three cheA genes were created using single cross-over homologous recombination insertion. We studied the phenotypes of the cheA mutants in detail and discovered that ?cheA-3 has a non swarming/swimming phenotype both in the soft agar plates and Palleroni chamber assays. CheA-3 shows similarity to the Shewanella oneidensis CheA-3 and the Vibrio cholerae CheA-2 that are responsible for chemotaxis in the respective organisms. We did not find any morphological or structural differences between the three Delta cheA mutants and the wild type cells in electron microscopy. Our results from these studies are presented.

Poster presented at the 2019 Texas Conference on Digital Libraries (TCDL-2019). This poster discusses how inter-departmental partnerships, particularly between UNT's Digital Libraries and Department of Photography and Studio Art can provide a win win collaborative environment for all parties involved. While the Digital Projects Lab can hire experienced photographers to operate and oversee its capturing system, as the same time MFA students can gain high level photography experiences in a real world project outside of the College of Visual Arts and Design which would help them diversify their skillset.

This poster discusses how forgiveness of self may be more effective for HIV+ individuals with a negative self-image.

This poster illustrates a study to determine if concerns and depression change over time for each gender after receiving an HIV diagnosis and throughout the disease course.

This poster examines how stigma encourages maladaptive coping strategies, which may discourage people living with HIV from seeking medical treatment.

Poster presented at the 2019 Texas Conference on Digital Libraries (TCDL-2019). This poster discusses about the University of North Texas' archive of government websites known as the CyberCemetery. The UNT Libraries have begun to extract documents embedded within the vast collection of web archives. Many of these documents include reports and transcripts from the various committees and agencies found in the collections. Through this project, the UNT Digital Library expands its role as a steward of digital resources in addition to making information easier to find.
