Palmitoyl-acyl carrier protein thioesterase in cotton (Gossypium hirsutum L.): biochemical and molecular characterization of a major mechanism for the regulation of palmitic acid content.

Palmitoyl-acyl carrier protein thioesterase in cotton (Gossypium hirsutum L.): biochemical and molecular characterization of a major mechanism for the regulation of palmitic acid content.

Date: August 2001
Creator: Huynh, Tu T
Description: The relatively high level of palmitic acid (22 mol%) in cottonseeds may be due in part to the activity of a palmitoyl-acyl carrier protein (ACP) thioesterase (PATE). In embryo extracts, PATE activity was highest at the maximum rate of reserve accumulation (oil and protein). The cotton FatB mRNA transcript abundance also peaked during this developmental stage, paralleling the profiles of PATE enzyme activity and seed oil accumulation. A cotton FatB cDNA clone was isolated by screening a cDNA library with a heterologous Arabidopsis FatB probe (Pirtle et al., 1999, Plant and Cell Physiology 40: 155-163). The predicted amino acid sequence of the cotton PATE preprotein had 63% identity to the Arabidopsis FatB thioesterase sequence, suggesting that the cotton cDNA clone probably encoded a FatB-type thioesterase. When acyl-CoA synthetase-minus E. coli mutants expressed the cotton cDNA, an increase in 16:0 free fatty acid content was measured in the culture medium. In addition, acyl-ACP thioesterase activity assays in E. coli lysates revealed that there was a preference for palmitoyl-ACP over oleoyl-ACP in vitro, indicating that the cotton putative FatB cDNA encoded a functional thioesterase with a preference for saturated acyl-ACPs over unsaturated acyl-ACPs (FatA). Overexpression of the FatB cDNA in transgenic cotton ...

The Papal Aggression: Creation of the Roman Catholic Hierarchy in England, 1850

The Papal Aggression: Creation of the Roman Catholic Hierarchy in England, 1850

Date: January 1969
Creator: Paz, D.G. (Denis G.)
Description: This thesis studies the Papal Aggression in England, which was the zealous reaction to a papal decree that had created territorial hierarchy for English Roman Catholics. The study seeks answers to the following questions: Why did the pope create the heirarchy? Why did the English people react so vehemently? Why did Lord John Russell write his Durham Letter? Why did the government fail to enforce the Ecclesiastical Titles Act? What light, if any, does this episode shed on the zeitgeist of the Victorian Age?

Paradox and Balance in the Anglo-Saxon Mind of Beowulf

Paradox and Balance in the Anglo-Saxon Mind of Beowulf

Date: May 2008
Creator: Fox, Bonnie L.
Description: This essay argues that the Anglo-Saxon poet of Beowulf presents the reader with a series of paradoxes and attempts to find a balance within these paradoxes. At the forefront is the paradox of past and present, explored through the influence of the past on the characters in the poem as well as the poet. Additionally, the poem offers the paradox of light and dark, which ultimately suggests light and dark as symbols of Christianity and paganism. Finally, the land and the sea offer the third primary paradox, indicating the relationship that the characters and poet had with land and sea, while also reflecting the other paradoxes in the poem. The result is the desire to find balance within the paradoxes through the recognition of ongoing tension.

The Paradox of Creativity and Business in Feature Hollywood Filmmaking: The Relationship Between Motion Picture Production and Budgeting

The Paradox of Creativity and Business in Feature Hollywood Filmmaking: The Relationship Between Motion Picture Production and Budgeting

Date: August 2005
Creator: Dean, Adam T.
Description: This study examines the relationship between movie budgeting and the creative process in Hollywood filmmaking. To understand the effects of this relationship on the creative product, several films are analyzed within the production process where conflicts between the investors and creators are observed. A case study approach is guided by theories of the production of culture, which state that creative products manufactured in the cultural industry must be analyzed in relation to their surrounds society. Findings suggest previous indicators of box office success are becoming primary influences in the filmmaking process. The study also finds that financial standards in Hollywood potentially inhibit innovation among creative participants within a limited Hollywood creative sphere.

The Paradox of the Christian Poet: George Herbert's Problematics

The Paradox of the Christian Poet: George Herbert's Problematics

Date: August 2000
Creator: Casey, James Edward
Description: The thesis examines the paradoxes in Herbert's poetry and attributes the many contradictions and vacillations within The Temple to Herbert's own "spiritual conflicts" as a Christian poet. The thesis explores the poems as interconnected expressions of Herbert's dual nature as Christian-Poet. The thesis discusses over sixty of Herbert's poems, concentrating on close readings and intratextual connections. Chapter One reviews critical approaches to Herbert's poetry and outlines the study. Chapter Two examines Herbert's life and the expression of his struggles in poetry. Chapter Three discusses Herbert's poetry itself and comments on the deceptively simplistic style. Chapter Four explores the conflict between the worlds of the Christian and the poet. Chapter Five concludes that, more than merely an artistic exercise or catechistic tool, Herbert's poetry accurately records the duality of the poet's spiritual journey.

Parallels Between the Gaming Experience and Rosenblatt's Reader Response Theory

Parallels Between the Gaming Experience and Rosenblatt's Reader Response Theory

Date: May 2013
Creator: Sanders, April
Description: The world of literacy has expanded alongside technology, and new literacies are being used as an alternative or an addition to traditional text. By including video gaming as literacy, the connection can be made between students' multimodal world outside of school with the world of literacy they encounter in school. This study took two approaches of a content study and a case study. A collective case study was used to examine the gaming experience of participants with three commercial video games falling into three separate genres: Sims FreePlay (simulation); Halo 1 (first person shooter); and World of Warcraft (role playing game). The 15 gamers were placed into three sets of five participants for each video game, and interviews were conducted to explore the gaming experience in relation to stance and transaction, which are major components of Louise Rosenblatt's reader response theory. Limited research has been conducted regarding reader response theory and the new literacies; by using the reader response lens, the gaming experience was compared to the reading experience to add the new literacies to the existing literature on reader response. As a way to look at both the text and the experience, a content study examined three mainstream video ...

A parametric analysis of the immediate and subsequent effects of response restriction on hand mouthing.

A parametric analysis of the immediate and subsequent effects of response restriction on hand mouthing.

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Soderlund, Michael J.
Description: The immediate and subsequent effects of different durations of response restriction were evaluated in a multiple schedule design. Response restriction components of 15, 30, and 60 minutes were conducted between 15 minute alone components. Levels of responding subsequent to the termination of response restriction procedures were compared to free operant levels prior to the implementation of response restriction. Responding during response restriction components reduced to near zero levels. Subsequent levels of responding were similar to or exceeded free operant baseline levels. Results are discussed in terms of potential operant mechanisms responsible for levels of responding subsequent to response restriction.
