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.

Novelas Indigenistas Representativas de America

Novelas Indigenistas Representativas de America

Date: May 1969
Creator: Rodríguez, David R.
Description: In this thesis have been included six novels of the indigenous type that represent four countries of Latin America: Mexico, Ecuador, Bolivia, and Peru. This type of novel contains elements of social protest, and therefore it is appropriate to examine the problem of the "indio" or (Indian) in relation to the countries where the majority of the population is comprised of "Indians".

Novice Generalist and Content teachers’ Perceptions of Contextual Factors Affecting Personal Teaching Efficacy

Novice Generalist and Content teachers’ Perceptions of Contextual Factors Affecting Personal Teaching Efficacy

Date: August 2011
Creator: Hooten, Dorleen Billman
Description: New teachers begin the school year with optimism and enthusiasm, but their excitement quickly wanes as they encounter the realities of the everyday life of a teacher. When they do not experience the successes they predicted, many begin to doubt their capabilities, which results in a lowered sense of teaching efficacy. This descriptive study was designed to identify the contextual factors novice teachers perceive as influences on personal teaching efficacy and to examine the relationships between the factors. Two groups of novice teachers who were concurrently enrolled in a post-baccalaureate accelerated educator preparation program and working as first-year teachers were the participants in the study. Data were gathered for the study through focus group activities, twice weekly journal entries completed during the teaching year, and a culminating “lessons learned” paper written during the last month of the first year of teaching. Each of the two focus groups identified nine contextual factors they perceived to affect personal teaching efficacy. Six factors were identified by both groups: parental involvement, support from administrators and colleagues, classroom discipline, testing results, teaching strategies and outcomes, and relationships with administrators and colleagues. The groups, however, perceived the relationships between the contextual factors differently. The generalists perceived ...

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.
