The Uptake Hydrogenase In The Unicellular Diazotrophic Cyanobacterium Cyanothece Sp. Strain Pcc 7822 Protects Nitrogenase From Oxygen Toxicity., Xiaohui Zhang, Debby Sherman, Louis A. Sherman

Department of Biological Sciences Faculty Publications

Cyanothece sp. strain PCC 7822 is a unicellular, diazotrophic cyanobacterium that can produce large quantities of H₂ when grown diazotrophically. This strain is also capable of genetic manipulations and can represent a good model for improving H₂ production from cyanobacteria. To this end, a knockout mutation was made in the hupL gene (ΔhupL), and we determined how this would affect the amount of H₂ produced. The ΔhupL mutant demonstrated virtually no nitrogenase activity or H₂ production when grown under N₂-fixing conditions. To ensure that this mutation only affected the hupL gene, …

Obm Thesis Project: Composing An Undergraduate Thesis Manual, William Strong

Honors Theses

The Behavioral Research Supervisory System (BRSS) is a class designed to assist undergraduate and master students in completing a thesis project in a timely manner. Prior to beginning this project, undergraduate students were not utilizing the thesis manual for the class effectively and master students did not have an effective tool to grade the quality of their undergraduate thesis students’ work. Therefore, the ultimate goal of this thesis project is to create a better manual for undergraduate students to reference while working on their thesis projects and to provide a systematic grading system for their graduate student supervisors. A pre-manual …

Vive Le Proletariat: The 1968 Revolt Of French Workers And Students, John Duhan

Honors Theses

1968 was a watershed year in terms of social change across the world. While countries behind the iron curtain like Czechoslovakia, Poland and Hungary were fighting for more reasonable government, western countries such as Germany, Italy, the United States, and France all dealt with uprisings from communist student groups. The unique aspect of the French Revolt of 1968, versus similar revolts in places such as The United States, or Germany, was the relationship between college students and members of the French working class.

For this essay I split the French working class into two separate groups: the immigrant workers, and …

Identity And Gender Constructs In "Written On The Body", Paige Van De Winkle

Honors Theses

In Jeanette Winterson's novel Written on the Body, the ungendered narrator leads the reader through his/her love story with Louise. At moments, the narrator appears to reveal his/her gender, but these moments only reveal the reader's own assumptions about gender and identity which prove to be social constructions, and inconclusive evidence about the narator's gender. The novel shows that gender is not an inherent part of identity, and emphasizes themes that are universal and more important than gender differences, such as biology and the body. The body proves to be beautiful and universal, and gender is an insignificant part …

Effective Teaching Practices To Strengthen Outcomes For Students With Emotional Behavior Disorders, Brittnae Cole

Honors Theses

Teachers of students with emotional and/or behavior disorders (E/BD) must use a variety of methodologies and interventions to address the varied academic and behavioral needs of their students (Walker & Gresham, 2013). Students identified as needing E/BD services require specific strategies that are researched based and have been proven to be successful in improving student outcomes (Kauffman & Landrum, 2009; Evans, Harden, & Thomas, 2004). After an extensive literature review from the past 10 years this paper presents some of the most frequently discussed research-based themes and subsequent interventions within the theme areas. The three most cited research-based themes presented …

On Stream Assessment: Human Perception And Spatiotemporal Delineation Of Geomorphic Units, Benjamin Franek

Doctoral Dissertations

The utility of human visual assessments to stream geomorphic unit delineation as part of project work inception has been established in the literature. However, certain issues arise. The impact of flow stage variation on stream geomorphic unit (SGU) distribution is not well known and the relatively short time that is spent conducting a visual assessment is not adequate to sufficiently understand the stream spatiotemporal dynamic. Also, critical assumptions regarding personal proficiency with visual assessments are embraced, yet often go untested. Even more, various disciplines are discordant in the way they identify and define stream units – interpersonal differences lead to …

Family Processes As Moderators Of The Impact Of Peer, School, And Neighborhood Influences On Adolescent Aggression, Alison Kramer-Kuhn

Theses and Dissertations

Despite theoretical support for the role of the family in providing a foundation to protect youth against risks for aggression, there is little published literature examining a protective influence. This study examined family functioning and perceived parental messages about fighting and nonviolence as moderators of the relation between risk factors and adolescent aggression. The specific risk factors included affiliating with a delinquent group of peers, attending a school with norms that support aggression, and witnessing violence within the community. Secondary analyses were conducted on data collected from a high-risk sample of 537 adolescents in 2 cohorts from 18 schools. Adolescents …

Axiom, Jon Fila, Peter Klinkon

Theses

Axiom is a short narrative video, using live-action and 3D computer graphics to re-interpret the Greek myth of Persephone through the framework of contemporary science-fiction. The aim of the video is to use narrative, approached from a design strategy that thematizes the representational role of 3D computer generated graphics, to raise questions in the minds of thoughtful viewers about the use of genetics and computer simulated worlds in the context of the vulnerable natural environment. The conceptualization of the video is explained, followed by a summary of the production pipeline, and finally an evaluation of the finished piece.

Cfx Analysis Of The Heat And Mass Transfer During The Chilling Of A Lamb Carcass Using A 3d Model, Joseph Hannon, Garrett Keane, Micheal O'Flaherty

Presentations

Lamb meat is a popular red meat which must go through a complex refrigeration process before being served at the dinner table to reduce bacterial growth and retain meat quality. A major disadvantage of chilling is the drip losses which are losses in weight by evaporation of water contained within the meat. The aim of this work is to simulate the conventional chilling process of a lamb carcass using a three dimensional model.

Comparison Of Finite Difference And Finite Element (Telemac) Models Of Dublin Bay, Garrett Keane, Zeinab Bedri, John O'Sullivan

Presentations

A number of hydrodynamic and solute mathematical models of Dublin Bay have been developed in the Centre for Water Resources Research in University College Dublin. One of these was an Eulerian-Langrangian finite difference Extended Dublin Bay model named SW2D which was developed by Hussey (1996). It was used in various studies such as the Dublin Bay Water Quality Management Plan and the Howth Outfall Study to predict the effect of the proposed upgrades at the sewage treatment plants on the water quality in these areas. The finite element TELEMAC modelling system developed by the French EDF group was used in …

Creating, Sharing And Reusing Learning Objects To Enhance Information Literacy, Philip Russell, Gerard Ryder, Gillian Kerins, Margaret Phelan

Support services (Former ITT) - Articles

From June 2010 until the present, a suite of online reusable learning objects (RLOs) has been created by staff at the Technological University Dublin (ITT Dublin) library covering a range of information literacy (IL) competencies. These RLOs have helped to facilitate student transition from second to third level, advance IL and enrich the student learning experience. The purpose of this paper is to outline the development of these RLOs and how the resources have been shared, reused and repurposed to enhance IL progression. A review of recent literature explores some of the key issues around the creation of digital learning …

Promoting Student Engagement Within A Practical Class Through The Use Of A Learning Portfolio, Niall Delaney, John A. Nolan

Conference papers

This paper looks at an exploratory case-study undertaken to try and investigate student engagement within a practical wood machining class.

Due to the nature of the course and the cohort of students, the current lecturer pedagogic practice has to be behaviourist, but from this a culture of expectancy has developed among the students. It was felt that something had to be done to revitalise student interest in the work they were doing and also give them the chance to address the perceived shortfall in their learning. There was potential for a lot of failures, but also much worse, there was …

Physical Design Of A Smart Camera With Integrated Digital Pixel Sensors Using A 0.13Μm 8-Layer Metal Cmos Process, Mahir K. Gharzai

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

The design of cameras has historically kept imagery and computational circuitry isolated in an attempt to maximize image quality by improving pixel pitch and routing density. Although this technique has worked in creating high density arrays of pixels for large resolution imagers, it has never been able to achieve high framerate computational operations.

A radical approach is introduced to solve this dilemma by creating compact, low- power pixel elements with built-in analog-to-digital converters that directly interface with digital logic. These pixels are capable of integrating alongside logic cells and to create an array of pixels inside the processor that can …

Swine manure slurry was land applied to 0.75m wide by 4.0m long plots established on an Aksarben silty clay loam soil located in southeast Nebraska. The treatment factor manure amendment consisted of two levels: no manure application and manure application to meet the 3 year nitrogen (N) requirements for corn. The treatment factor of grass hedge was established for half of …

Veteran Identity And Gender Representation: A Critical Visual Analysis, Ruth Harvie

Theses

This study reveals struggles over gender and identity in the military and shows how representations embody cultural, political, and ideological tensions over the role of women in the military and society. A chronological series of Veterans Affairs (VA) posters communicate this over a thirty year period. Visual communication and the area of representation and identity have long been studied across multiple disciplines, but no studies exist that examine the VA images. A critical visual analysis with the application of semiotics and gender theory revealed that veteran identity is significantly different between representation of men and representation of women.

Needs Met Through Role-Playing Games: A Fantasy Theme Analysis Of Dungeons & Dragons, Aubrie S. Adams

Kaleidoscope: A Graduate Journal of Qualitative Communication Research

Dungeons & Dragons (D&D) is an immersive fantasy role-playing game (RPG) which allows players to fulfill real-world social needs through interaction. Although D&D may appear to be a game of simple make-believe, the emotions, camaraderie, and accomplishments experienced by players are real, thus suggesting that RPGs have real-world implications for players. Therefore, the goal of this study is to explore the ways in which players fulfill social needs through group communication during the context of D&D table-top role-play. Utilizing Bormann’s (1972) fantasy theme analysis, this study uses a case study approach to identify four themes which emerged within player talk …

The Hero Of Copyright Reform: Exploring Non-Cochlear Impacts Of Girl Talk’S Plunderphonics, C. Austin Mcdonald Ii

Kaleidoscope: A Graduate Journal of Qualitative Communication Research

The history of audio sampling reaches as far back as the phonograph (Miller, 2004). Although many artists have utilized pastiche and collage in their work, few scholars have examined the products, processes, and implications of sound collage. This paper utilizes Kim-Cohen’s (2009) call for “non-cochlear” analyses of sound to examine the career and works of mashup artist Gregg Gillis, or Girl Talk. Kim-Cohen’s (2009) non-cochlear approach asks us to connect “sonic arts to broader textual, conceptual, social, and political concerns” (p. xix). Appropriately, I contend that Girl Talk’s sound collage albums prompt listeners to think in non-cochlear terms regarding progressive …

Lines Of Flight: A Rhizomatic Exploration Of Transparency In Three International Humanitarian Sites, Carmen S. Lowry

Kaleidoscope: A Graduate Journal of Qualitative Communication Research

In this essay, I apply a rhizome metaphor to explore the ways transparency functions in three humanitarian sites. Using a case study method, I investigate how transparency functioned in a resettlement program following communal violence in Indonesia, an emergency response program following Cyclone Nargis in Burma, and a gender-based violence program in Sudan. Through my analysis, I suggest that transparency is a communicative act that has both short and long-range implications for all parties involved, however removed, from the research or intervention project.

Improving The Performance Of Supercritical Co2 As An Oil Recovery Solvent, Robert M. Enick

Amgen Seminar Series in Chemical Engineering

Nearly 5% of the oil produced in the US (about 300,000 barrels of oil each day) is attributable to the injection of supercritical CO2 into subterranean sandstone or carbonate formations. Even though this technology has been used safely and successfully for over 40 years, it is plagued by problems related to the low viscosity of CO2. At reservoir conditions, the viscosity of CO2 is about 0.05 cp, while the viscosity of the crude oil is typically in the 1-10 cp range. As a result, the CO2 tends to "finger" from the injection well, through the formation, toward the production wells …

Moral Turbulence And The Infusion Of Multimodal Character Education Strategies In American Elementary Schools, Mark A. Lamport, Ph.D., Kristi L. Cobb, M.A.

Christian Perspectives in Education

Pockets of American society are marked by increase in violent crime with concurrent decline in moral character. This phenomenon is infiltrating the nation’s school system as evidenced by growing numbers of aggressive incidents in the classroom. As a result, there is an increasingly accepted need for effective character education programs in the schools as a means to help change the décolleté trajectory of the behavior of the nation’s school children. While more money and growing numbers of legislation have been put forth to support such an endeavor, research is still lacking as to what activities, skills, goals, and approaches would …
