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.

Center for Volcanic and Tectonic Studies: 1992--1993 annual report

Center for Volcanic and Tectonic Studies: 1992--1993 annual report

Date: December 31, 1994
Creator: unknown
Description: The annual report of the Center for Volcanic Studies (CVTS) contains a series of papers, reprints and a Master of Science thesis that review the progress made by the CVTS between October 1, 1992 and February 1, 1994. During this period CVTS staff focused on several topics that have direct relevance to volcanic hazards related to the proposed high-level nuclear waste repository at Yucca Mountain, Nevada. These topics include: (1) polygenetic/polycyclic volcanism in Crater Flat, Nevada; (2) the role of the mantle during crustal extension; (3) the detailed geology of Crater Flat, Nevada; (4) Pliocene volcanoes in the Reveille Range, south-central Nevada; (5) estimating the probability of disruption of the proposed repository by volcanic eruptions. This topic is being studied by Dr. C.H. Ho at UNLV. The report contains copies of these individual papers as they were presented in various conference proceedings.

UTSI/CFFF MHD PROGRAM COMPLETION AND RELATED ACTIVITY

UTSI/CFFF MHD PROGRAM COMPLETION AND RELATED ACTIVITY

Date: August 1, 2000
Creator: Unknown
Description: Maintenance work on the DOE CFFF facility and other related government property is no longer authorized under this contract in accordance with the DOE-UT Settlement Agreement. Environmental remediation preservation of the facility continued. Government property has been transferred to UTSI as owner which frees up many items for proper disposal. Actions are underway to dispose of other wastes, and control pests and water at the DOE CFFF. Only one high temperature superconductivity project is active under Task 6. Under the particular Subtask 6.02, samples of nickel obtained from Plastronics, Inc. were coated with the LAO precursor solution. These coated samples have been characterized using the x-ray diffraction unit, and the results from the x-ray diffraction characterizations were further analyzed using a statistical program to develop multi-regression coefficients. Based on these regression coefficients, the variables that have significant effect on the coating of LAO over nickel substrate have been identified. A Master of Science thesis was prepared describing these findings and it will be defended in front of the committee members during July, 2000.

The Historical Development and Future of the National Technological University

The Historical Development and Future of the National Technological University

Date: August 1988
Creator: Mays, Marilyn Elaine
Description: The National Technological University (NTU), a consortium of more than twenty American engineering schools, broadcasts courses produced at member institutions to professional engineers at corporate sites across the country. It is a nonprofit institution.begun in fall 1984 with headquarters in Fort Collins, Colorado, which offers only course work leading to the Master of Science degree in various branches of technology, or applied science. Students must be sponsored by their corporate employers who pay their tuition. This is the first systematic examination of the instructional process at an educational institution created in response to the demands of the governmental and corporate sectors' technological needs. This study includes an attempt to explore the effectiveness of that instructional process and the use of computers in distance education at NTU and implications for institutions of the future. This study focuses on distance education, corporate education, national universities and nontraditional institutions and the extent to which NTO exemplifies each of these concepts. It covers the organizational structure and methods of operation of NTU, and offers opinions of students, faculty, and other personnel associated with the institution as reflected by surveys, interviews, and the media.

Ambient and elevated temperature fracture and cyclic-fatigue properties in a series of Al-containing silicon carbides

Ambient and elevated temperature fracture and cyclic-fatigue properties in a series of Al-containing silicon carbides

Date: August 30, 2004
Creator: Yuan, Rong
Description: A series of in situ toughened, Al, B and C containing, silicon carbide ceramics (ABC-SiC) has been examined with Al contents varying from 3 to 7 wt%. With increasing Al additions, the grain morphology in the as-processed microstructures varied from elongated to bimodal to equiaxed, with a change in the nature of the grain-boundary film from amorphous to partially crystalline to fully crystalline. Fracture toughness and cyclic fatigue tests on these microstructures revealed that although the 7 wt.% Al containing material (7ABC) was extremely brittle, the 3 and particularly 5 wt.% Al materials (3ABC and 5ABC, respectively) displayed excellent crack-growth resistance at both ambient (25 C) and elevated (1300 C) temperatures. Indeed, no evidence of creep damage, in the form of grain-boundary cavitation, was seen at temperatures at 1300 C or below. The enhanced toughness of the higher Al-containing materials was associated with extensive crack bridging from both interlocking grains (in 3ABC) and uncracked ligaments (in 5ABC); in contrast, the 7ABC SiC showed no such bridging, concomitant with a marked reduction in the volume fraction of elongated grains. Mechanistically, cyclic fatigue-crack growth in 3ABC and 5ABC SiC involved the progressive degradation of such bridging ligaments in the crack wake, with ...
