A Multimedia Atlas of Dissection for Comparative Anatomy of the Vertebrates

A Multimedia Atlas of Dissection for Comparative Anatomy of the Vertebrates

Access: Use of this item is restricted to the UNT Community.
Date: August 1999
Creator: Curran, Anthony A., Jr.
Description: This interactive multimedia content is part of the thesis that was prepared for the degree of Master of Science in Biology: http://digital.library.unt.edu/ark:/67531/metadc2224. Traditional methods of teaching the laboratory course for Comparative Anatomy of the Vertebrates could be improved by applying current computer technology to construct an interactive, multimedial atlas of dissection. Five specimens used in comparative anatomy courses at most institutions were chosen as representative members of the Phylum Chordata: amphioxus, lamprey, dogfish shark, mud puppy, and cat. Specimens were dissected according to the modified method of Wischnitzer, 1993, and each stage was photographed with a Kodak DC120 digital zoom camera. These images were processed on a Power Macintosh 7600 computer with Adobe Photoshop v. 5.0. The atlas was constructed from these images using Macromedia Authorware v. 4.0.3. Each image contains a series of interactive objects that display a highlight and descriptive text as the cursor passes over each object.

Stoichiometry and Deposition Temperature Dependence  of the Microstructural and Electrical Properties of Barium Strontium Titanate Thin Films

Stoichiometry and Deposition Temperature Dependence of the Microstructural and Electrical Properties of Barium Strontium Titanate Thin Films

Date: May 1998
Creator: Pena, Piedad
Description: Barium Strontium Titanate (BST) was deposited on Pt/ZrO2 / SiO2/Si substrates using liquid source metal organic chemical vapor deposition. A stoichiometry series was deposited with various GrII/Ti ratios (0.658 to 1.022) and a temperature series was deposited at 550 to 700°C. The thin films were characterized using transmission electron microscopy. Both series of samples contained cubic perovskite BST and an amorphous phase. The grain size increased and the volume fraction of amorphous phase decreased with increasing deposition temperature. The electrical and microstructural properties improved as the GrII/Ti ratio approached 1 and deteriorated beyond 1. This research demonstrates that BST thin films are a strong candidate for future MOS transistor gate insulator applications.

Synthesis, structure and redox reactivity of Co₃(CO)₆(μ₂-η²,η¹-C(Ph)C=C(PPH₂)C(O)SC(O)) (μ₂-PPh₂)

Synthesis, structure and redox reactivity of Co₃(CO)₆(μ₂-η²,η¹-C(Ph)C=C(PPH₂)C(O)SC(O)) (μ₂-PPh₂)

Date: May 1994
Creator: Muñoz, Trinidad
Description: The tricobalt cluster PhCCo₃(CO)₉ (1) reacts with the bidentate phosphine ligand 2,3-bis(diphenylphosphino)maleic thioanhydride (bta) with added Me₃NO to yield PhCCo₃(CO)₇(bta) (2), which upon heating overnight yields Co₃(CO)₆(μ₂-η²,η¹-C(Ph)C=C(PPH₂)C(O)SC(O)) (μ₂-PPh₂) (3). Cluster (3) has been isolated and characterized by FT-IR and ³¹P NMR spectroscopy. Structural determination of the cluster has been demonstrated by X-ray diffraction analysis. Cluster (3) is analogous to the cluster synthesized by Richmond and coworkers. The redox properties of (3) have been examined by cyclic voltammetry and the data are reported within.

Designing a Social Marketing Plan to Promote Hispanic Participation at Prostate Cancer Screenings

Designing a Social Marketing Plan to Promote Hispanic Participation at Prostate Cancer Screenings

Date: December 1995
Creator: Zimmerman, Suzanne M. (Suzanne Marie)
Description: Prostate cancer is the most commonly occurring cancer and the second leading cause of cancer death for men in the United States. Because early prostate cancer is frequently without symptoms and data on how to prevent prostate cancer is lacking, early detection has the greatest potential for decreasing mortality. Studies have shown Hispanics/Latinos to be less likely than whites or African-Americans to utilize prostate cancer screening exams. The purpose of this descriptive study was to design a social marketing plan which could be used as a model to promote Hispanic/Latino participation at prostate cancer screenings. Information obtained through medical and marketing literature review, the author's experiences serving on the promotion committee of a community-sponsored prostate cancer screening project, and interviews with 51 Hispanic/Latino prostate cancer screening participants is described and incorporated into a guide with recommendations for future program planners.

Survey of the Solid State Conformation of Calix[4]arenes

Survey of the Solid State Conformation of Calix[4]arenes

Date: August 1997
Creator: Obrey, Stephen J. (Stephen James)
Description: The characteristics of seventy-six calix[4]arene crystal structures derived from the Cambridge Crystallographic Database are presented. This survey is a discussion of the inter and intramolecular effects on the solid state cavity shape and molecular recognition ability of the compounds. In addition to this survey, four new calix[4]arene crystal structures are presented. The conformational characteristics of these four calixarenes are determined by a complicated array of inter and intramolecular interactions in the crystal packing.

Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes

Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes

Date: December 1997
Creator: Boyd, Charlotte Friedersdorff
Description: Much research has been undertaken to determine how Subject Matter Expert characteristics affect job analysis outcomes. The current study seeks to discover if performance levels are related to current incumbents ratings of their positions. A group of 114 corporate associates, from two administrative positions, served as Subject Matter Experts (SME) for this study. Separate job analyses for each position were conducted using the Job Analysis Task Checklist. The results for each job were analyzed to determine if SME performance levels affected job analysis outcomes. The results for both jobs showed that there were very few differences in job analysis results as a function of SME performance levels.

DNA Typing of HLA-B by PCR with Primer Mixes Utilizing Sequence-Specific Primers

Date: August 1997
Creator: Chiu, Angela Chen-Yen
Description: The aim of this study was to design a resolution typing system for the HLA-B gene. This technique involves a one-step PCR reaction utilizing genomic DNA and sequence-specific primers to determine the specificity of each allele and to produce a larger primer data base ideal for serological analysis. The application of this technique to serological analysis can improve serology detection which is currently hindered by antibody cross-reactivity and the unavailability of useful typing reagents.

A Study of the Relationships among Relational Maintenance Strategy Usage, Communicator Style and Romantic Relational Satisfaction

A Study of the Relationships among Relational Maintenance Strategy Usage, Communicator Style and Romantic Relational Satisfaction

Date: August 1996
Creator: Hardin, Charla (Charla LeeAnn)
Description: This thesis examined student-participants' self-reported use of romantic relational maintenance strategies and their partners' reports of relational satisfaction. Additionally, individuals outside the romantic relationship reported on student-participants' general communicator style. The research proposed that general style reports would be predictive of relational maintenance strategy usage and of romantic partners' relational satisfaction. The study found that general style behaviors may not be indicative of relational maintenance strategy usage or romantic partners' relational satisfaction. Tests of sex differences revealed that females' expression of various relational maintenance strategies and style behaviors are associated with male partners' relational satisfaction; however, no results were obtained indicating specific behaviors expressed by males result in female partners' relational satisfaction.
