Novice Teachers' Stories Represented As a Graphic Narrative

Novice Teachers' Stories Represented As a Graphic Narrative

Date: May 2013
Creator: Deardorff, Philip
Description: The issue of alternative certification teacher training has greatly affected art education over three decades. As a result of training through alternative certification, many art educators enter the profession unprepared and unable to cope with the realities of teaching. This study attempts to understand and represent the experiences and struggles of four alternatively certified art teachers, including myself. By reading these stories, others within the education community can empathize with and provide support for struggling novice teachers. This creative thesis uses a graphic novel format to represent participants' stories. By combining text and imagery, the graphic novel format provides different meanings, interpretations, and insights into the teachers' lives. This medium offered a unique and rich perspective on the stories of what it is like being an alternatively certified art teacher.

De novo prediction of the ground state structure of transition metal complexes.

De novo prediction of the ground state structure of transition metal complexes.

Access: Use of this item is restricted to the UNT Community.
Date: December 2004
Creator: Buda, Corneliu
Description: One of the main goals of computational methods is to identify reasonable geometries for target materials. Organometallic complexes have been investigated in this dissertation research, entailing a significant challenge based on transition metal diversity and the associated complexity of the ligands. A large variety of theoretical methods have been employed to determine ground state geometries of organometallic species. An impressive number of transition metals entailing diverse isomers (e.g., geometric, spin, structural and coordination), different coordination numbers, oxidation states and various numbers of electrons in d orbitals have been studied. Moreover, ligands that are single, double or triple bonded to the transition metal, exhibiting diverse electronic and steric effects, have been investigated. In this research, a novel de novo scheme for structural prediction of transition metal complexes was developed, tested and shown to be successful.

Now All the Fingers of This Tree

Now All the Fingers of This Tree

Date: May 2003
Creator: Wood, Kelly Thomas
Description: Now All the Fingers of This Tree is a work in two movements based upon a poem of the same name by E. E. Cummings. It is divided into two movements: The first movement is scored for nine part solo soprano, where one performer records each of the nine vocal lines. The second movement is an electro-acoustic work derived from four phrases of the original recording of the first movement. Total duration of the work is approximately 19 minutes. The paper provides a detailed analysis of both movements as well as a discussion on usage of text, problems addressed with traditional notation techniques, and technology utilized in the production of the work.

"Now His Time Really Seems to Have Come": Ideas about Mahler's Music in Late Imperial and First Republic Vienna

"Now His Time Really Seems to Have Come": Ideas about Mahler's Music in Late Imperial and First Republic Vienna

Date: December 2009
Creator: Kinnett, Forest Randolph
Description: In Vienna from about 1918 until the 1930s, contemporaries perceived a high point in the music-historical significance of Mahler's works, with regard to both the history of compositional style and the social history of music. The ideas and meanings that became attached to Mahler's works in this milieu are tied inextricably to the city's political and cultural life. Although the performances of Mahler's works under the auspices of Vienna's Social Democrats are sometimes construed today as mere acts of political appropriation, David Josef Bach's writings suggest that the innovative and controversial aspects of Mahler's works held social value in line with the ideal of Arbeiterbildung. Richard Specht, Arnold Schoenberg, and Theodor Adorno embraced oft-criticized features in Mahler's music, regarding the composer as a prophetic artist whose compositional style was the epitome of faithful adherence to one's inner artistic vision, regardless of its popularity. While all three critics addressed the relationship between detail and whole in Mahler's music, Adorno construed it as an act of subversion. Mahler's popularity also affected Viennese composers during this time in obvious and subtle ways. The formal structure and thematic construction of Berg's Chamber Concerto suggest a compositional approach close to what his student Adorno described ...

NSAID effect on prostanoids in fishes: Prostaglandin E2 levels in bluntnose minnows (Pimephales notatus) exposed to ibuprofen.

NSAID effect on prostanoids in fishes: Prostaglandin E2 levels in bluntnose minnows (Pimephales notatus) exposed to ibuprofen.

Date: August 2009
Creator: Bhandari, Khageshor
Description: Prostanoids are oxygenated derivatives of arachidonic acid with a wide range of physiological effects in vertebrates including modulation of inflammation and innate immune responses. Nonsteroidal anti-inflammatory drugs (NSAIDs) act through inhibition of cyclooxygenase (COX) conversion of arachidonic acid to prostanoids. In order to better understand the potential of environmental NSAIDS for interruption of normal levels COX products in fishes, we developed an LC/MS/MS-based approach for tissue analysis of 7 prostanoids. Initial studies examining muscle, gut and gill demonstrated that prostaglandin E2 (PGE2) was the most abundant of the measured prostanoids in all tissues and that gill tissue had the highest and most consistent concentrations of PGE2. After short-term 48-h laboratory exposures to concentrations of 5, 25, 50 and 100 ppb ibuprofen, 50.0ppb and 100.0 ppb exposure concentrations resulted in significant reduction of gill tissue PGE2 concentration by approximately 30% and 80% respectively. The lower exposures did not result in significant reductions when compared to unexposed controls. Measured tissue concentrations of ibuprofen indicated that this NSAID had little potential for bioaccumulation (BCF 1.3) and the IC50 of ibuprofen for inhibition of PGE2 production in gill tissue was calculated to be 0.4 µM. Short-term laboratory exposure to ibuprofen did not result in ...

Nuclear Magnetic Resonance Spectra of Some 1,2,4-triazoles

Nuclear Magnetic Resonance Spectra of Some 1,2,4-triazoles

Date: January 1967
Creator: Creagh, Linda Truitt
Description: In the work undertaken here, NMR has been used to ascertain the structure of some 1,2,4-triazoles. The investigation provides information concerning the structure of potentially tautomeric triazoles such as hydroxy- and aminotriazole. Connected with this aspect of triazole chemistry is the larger problem of mesohydric tautomerism. The present study also yields information for a comparison of substituent effects in triazoles, N-heteroaromatic substances and benzene.

Nucleotide Inhibition of Glyoxalase II

Nucleotide Inhibition of Glyoxalase II

Date: May 1999
Creator: Gillis, Glen S
Description: The glyoxalase system mediates the conversion of methylglyoxal, a toxic ketoaldehyde, to D-lactic acid. The system is composed of two enzymes, glyoxalase I (Glo-I) and glyoxalase II (Glo-II), and exhibits an absolute requirement for a catalytic quantity of glutathione (GSH). Glo-I catalyzes the isomerization of a hemithioacetal, formed non-enzymatically from methylglyoxal and GSH, to the corresponding a -D-hydroxyacid thioester, s-D-lactoylglutathione (SLG). Glo-II catalyzes the irreversible breakdown of SLG to D-lactate and GSH. We have observed that ATP or GTP significantly inhibits the Glo-II activity of tissue homogenates from various sources. We have developed a rapid, one step chromatography procedure to purify Glo-II such that the purified enzyme remains "sensitive" to inhibition by ATP or GTP (Glo-II-s). Studies indicate that inhibition of Glo-II-s by nucleotides is restricted to ATP, GTP, ADP, and GDP, with ATP appearing most effective. Kinetics studies have shown that ATP acts as a partial non-competitive inhibitor of Glo-II-s activity, and further suggest that two kinetically distinguishable forms of the enzyme exist. The sensitivity of pure Glo-II-s to nucleotide inhibition is slowly lost on storage even at -80° C. This loss is accelerated at higher temperatures or in the presence of ATP. Kinetics studies on the resultant "insensitive" ...
