Nopalita: A Mythology of Cultural Self-Representation

Nopalita: A Mythology of Cultural Self-Representation

Date: August 2004
Creator: Medina, Cristina Blasa
Description: The first segment introduces the background information on the use of paños as art by prisoners and how I appropriate the same materials to create and record my own cultural mythology. The Statement of Problem and Questions are about how and what cultural information is chosen in creating a visual mythology. The second segment explains the invention of the mythology by describing why certain experiences were chosen, specifically those of the graduate school experience. Also the development of self-representation through self-portraits is described. The third segment explains the symbolism used in the imagery, such as the cacti as cultural indicator and palimpsest. The fourth segment is a conclusion involving the realization that feeling caught within a hybrid culture is an important part of my identity.

The North American Carbon Budget and Implications for the Global Carbon Cycle

The North American Carbon Budget and Implications for the Global Carbon Cycle

Date: November 2007
Creator: U.S. Climate Change Science Program and the Subcommittee on Global Change Research.
Description: A primary objective of the U.S. Climate Change Science Program (CCSP) is to provide the best possible scientific information to support public discussion, as well as government and private sector decision making, on key climate-related issues. To help meet this objective, the CCSP has identified an initial set of 21 Synthesis and Assessment Products (SAPs) that address its highest priority research, observation, and decision support needs. This report-CCSP SAP 2.2-addresses Goal 2 of the CCSP Strategic Plan: Improve quantification of the forces bringing about changes in the Earth's climate and related systems. The report provides a synthesis and integration of the current knowledge of the North American carbon budget and its context within the global carbon cycle. In a format useful to decision makers, it (1) summarizes our knowledge of carbon cycle properties and changes relevant to the contributions of and impacts upon North America and the rest of the world, and (2) provides scientific information for decision support focused on key issues for carbon management and policy. Consequently, this report is aimed at both the decision-maker audience and to the expert scientific and stakeholder communities.

North American Indian Mythology and Folklore for Secondary School Students

North American Indian Mythology and Folklore for Secondary School Students

Date: January 1970
Creator: Jackson, Sarah
Description: Through a study of North American Indian folklore and mythology, the non-Indian can at last begin to know the Indian with whom he has shared a continent and to find out something of his religion, traditions, history, humor, and tribal peculiarities. The approach to this study through motifs, already familiar to the students from other literature, offers a practical approach and one that can be adapted to classroom use, perhaps either in the study of myth, the study of literary types, the study of literature per se, or perhaps in the study of cultural differences.

The North Texas Region and the Development of Water Resources in the Trinity River Basin of Texas, 1840-1998

The North Texas Region and the Development of Water Resources in the Trinity River Basin of Texas, 1840-1998

Date: August 1999
Creator: Sparkman, Michael D.
Description: This study focuses on the development of water resources in the Trinity River basin for navigation, flood control, water supply, recreation, and allied purposes. Special emphasis is given to the development of the upper Trinity River basin through the influence of community leaders in Dallas and Fort Worth. A desire harbored for generations by upper basin residents for creating a navigable waterway on the Trinity River coalesced in the twentieth century into a well organized movement for all facets of water resources development. Sources include correspondence, speeches, and promotional materials of civic leaders, politicians, and other citizens, as well as works by the United States Army Corps of Engineers.

A Novel Mechanism for Site-Directed Mutagenesis of Large Catabolic Plasmids Using Natural Transformation

A Novel Mechanism for Site-Directed Mutagenesis of Large Catabolic Plasmids Using Natural Transformation

Date: August 2001
Creator: Williamson, Phillip C.
Description: Natural transformation is the process by which cells take up DNA from the surrounding medium under physiological conditions, altering the genotype in a heritable fashion. This occurs without chemical or physical treatment of the cells. Certain Acinetobacter strains exhibit a strong tendency to incorporate homologous DNA into their chromosomes by natural transformation. Transformation in Acinetobacter exhibits several unique properties that indicate this system's superiority as a model for transformation studies or studies which benefit from the use of transformation as an experimental method of gene manipulation. Pseudomonas putida is the natural host of TOL plasmids, ranging between 50 kbp and 300 kbp in size and encoding genes for the catabolism of toluene, meta-toluate, and xylene. These very large, single-copy plasmids are difficult to isolate, manipulate, or modify in vitro. In this study, the TOL plasmid pDKR1 was introduced into Acinetobacter calcoaceticus strains and genetically engineered utilizing natural transformation as part of the process. Following engineering by transformation, the recombinant DNA molecule was returned to the native genetic background of the original host P. putida strain. Specific parameters for the successful manipulation of large plasmids by natural transformation in Acinetobacter were identified and are outlined. The effects of growth phase, total ...

A Novel Process for GeSi Thin Film Synthesis

A Novel Process for GeSi Thin Film Synthesis

Date: December 2007
Creator: Hossain, Khalid
Description: A unique process of fabricating a strained layer GexSi1-x on insulator is demonstrated. Such strained heterostructures are useful in the fabrication of high-mobility transistors. This technique incorporates well-established silicon processing technology e.g., ion implantation and thermal oxidation. A dilute GeSi layer is initially formed by implanting Ge+ into a silicon-on-insulator (SOI) substrate. Thermal oxidation segregates the Ge at the growing oxide interface to form a distinct GexSi1-x thin-film with a composition that can be tailored by controlling the oxidation parameters (e.g. temperature and oxidation ambient). In addition, the film thickness can be controlled by implantation fluence, which is important since the film forms pseudomorphically below 2×1016 Ge/cm2. Continued oxidation consumes the underlying Si leaving the strained GeSi film encapsulated by the two oxide layers, i.e. the top thermal oxide and the buried oxide. Removal of the thermal oxide by a dilute HF etch completes the process. Strain relaxation can be achieved by either of two methods. One involves vacancy injection by ion implantation to introduce sufficient open-volume within the film to compensate for the compressive strain. The other depends upon the formation of GeO2. If Ge is oxidized in the absence of Si, it evaporates as GeO(g) resulting in spontaneous ...

Novel Role of Trypsin in Zebrafish

Novel Role of Trypsin in Zebrafish

Access: Use of this item is restricted to the UNT Community.
Date: May 2013
Creator: Alsrhani, Abdullah Falleh
Description: It has been shown previously in our laboratory that zebrafish produce trypsin from their gills when they are under stress, and this trypsin is involved in thrombocyte activation via PAR2 during gill bleeding. In this study, I investigated another role of the trypsin that is secreted from zebrafish. This investigation has demonstrated a novel role of trypsin in zebrafish. Not only did this investigation demonstrate the role of trypsin in zebrafish behavior, but also it showed that PAR2 might be the receptor that is involved in trypsin-mediated behavioral response. In addition, we have shown that Gq and ERK inhibitors are able to block the trypsin pathway and prevent the escaping behavior. Finally, the results of this investigation suggest that the cells that respond to trypsin are surface cells, which have an appearance similar to that of neuromast cells.
