Timing And Spectroscopy Requirements For A Plastic Scintillating Fiber Bundle Time-Of-Flight Neutron Spectrometer, Paul A. Clement

Theses and Dissertations

The design parameters of a Time-of-Flight (TOF) neutron spectrometer composed of BCF-12 plastic scintillating fibers were investigated. A GEANT4 transport model was developed for analyzing the interaction of 2.5 MeV neutrons with a 14 x 14 BCF-12 fiber bundle. The bundle simulation demonstrated that 0.359% of all neutrons incident on the bundle will double scatter. The timing and data collection e efficiencies of a Tektronix DPO7104 series digital oscilloscope were examined to determine the signal processing requirements for future fiber bundle measurements. The minimum detectable neutron energy was computed by taking into account the bundle scintillation e efficiency, light collection …

Mems Cantilever Sensor For Thz Photoacoustic Chemical Sensing And Spectroscopy, Nathan E. Glauvitz

Theses and Dissertations

Sensitive Microelectromechanical System (MEMS) cantilever designs were modeled, fabricated, and tested to measure the photoacoustic (PA) response of gasses to terahertz (THz) radiation. Surface and bulk micromachining technologies were employed to create the extremely sensitive devices that could detect very small changes in pressure. Fabricated devices were then tested in a custom made THz PA vacuum test chamber where the cantilever deflections caused by the photoacoustic effect were measured with a laser interferometer and iris beam clipped methods. The sensitive cantilever designs achieved a normalized noise equivalent absorption coefficient of 2.83x10^-10 cm^-1 W Hz^-1/2 using a 25 …

Electronic And Physical Characterization Of Hydrothermally Grown Single Crystal Tho2, Tony D. Kelly Ii

Theses and Dissertations

Actinide single crystals are important to the fabrication of next generation electronic devices that could possibly have radiation with the atmosphere and surroundings. Th02 single crystals were obtained previous to this work by hydrothermal synthesis. As these crystals were the first of their kind, the geometric and electric structure of the crystals needed to be extracted. The valence and conduction bands were studied in order to ascertain the band gap using ultraviolet photoemission spectroscopy (UPS) and inverse photoemission spectroscopy (IPES). The unoccupied structure was further characterized using x-ray absorption near edge structure (XANES) and relativistic, real-space Green's functions calculations. The …

The Toxoplasma Gondii Cyst Wall Protein Cst1 Is Critical For Cyst Wall Integrity And Promotes Bradyzoite Persistence, Tadakimi Tomita, David J. Bzik, Yan Fen Ma, Barbara A. Fox

Dartmouth Scholarship

Toxoplasma gondii infects up to one third of the world's population. A key to the success of T. gondii as a parasite is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. Because most of the antibodies and reagents that recognize the cyst wall recognize carbohydrates, identification of the components of the cyst wall has been technically challenging. We have identified CST1 (TGME49_064660) as a 250 kDa SRS (SAG1 related sequence) domain protein with a large …

Efficient And Long-Time Accurate Second-Order Methods For The Stokes-Darcy System, Wenbin Chen, Max Gunzburger, Dong Sun, Xiaoming Wan

Mathematics and Statistics Faculty Research & Creative Works

We propose and study two second order in time implicit-explicit methods for the coupled Stokes-Darcy system that governs flows in karst aquifers and other subsurface flow systems. the first method is a combination of a second-order backward differentiation formula and the second order Gear's extrapolation approach. the second is a combination of the second-order Adams-Moulton and second-order Adams-Bashforth methods. Both algorithms only require the solution of decoupled Stokes and Darcy problems at each time-step. Hence, these schemes are very efficient and can be easily implemented using legacy codes. We establish the unconditional and uniform in time stability for both schemes. …

Understanding Human Learning Using A Multiagent Based Unified Learning Model Simulation, Vlad T. Chiriacescu

School of Computing: Dissertations, Theses, and Student Research

Within cognitive science, computational modeling based on cognitive architectures has been an important approach to addressing questions of human cognition and learning. Modeling issues such as limited expressivity in representing knowledge and lack of appropriate selection of model structure represent a challenge for existing architectures. Furthermore, latest research shows that the concepts of long-term memory, motivation and working memory are critical cognitive aspects but a unifying cognitive paradigm integrating those concepts hasn’t been previously achieved.

Derived from a synthesis of neuroscience, cognitive science, psychology, and education, the Unified Learning Model (ULM) provides this integration by merging a statistical learning mechanism …

The Use Of Lactic Acid Bacteria And Cellulolytic Bacteria To Improve The Chemical Properties Of Corn Flour, Elly Rosyidah, Anja Meryandini, Titi Candra Sunarti

Makara Journal of Science

Corn has the potential to be converted into flour, but its hard endosperm causies it to have a coarse particle size, and consequently, corn flour has high crude fiber, low protein, and high moisture. To overcome these problems, the milling of corn grain can be done by steeping it in water. The steeping process causes spontaneous growth of microbes, such as lactid acid bacteria and cellulolytic bacteria. The use of lactid acid bacteria and cellulolytic bacteria in the steeping process can soften the horny endosperm, which can enable corn grits to be ground into fine flours and which can improve …

Utilizing Gis To Examine The Relationship Between State Renewable Portfolio Standards And The Adoption Of Renewable Energy Technologies, Chelsea Schelly, Jessica Price

Department of Social Sciences Publications

In the United States, there is no comprehensive energy policy at the federal level. To address issues as diverse as climate change, energy security, and economic development, individual states have increasingly implemented Renewable Portfolio Standards (RPSs), which mandate that utility providers include a specified amount of electricity from renewable energy sources in their total energy portfolios. Some states have included incentives for individual energy technologies in their RPS, such as solar electric (also called photovoltaic or PV technology). Here, we use GIS to visualize adoption of RPSs and electricity generation from renewable energy sources in the US and examine changes …

Rna-Based System And Method To Differentiate Seafood, John H. Paul, David E. John

USF Patents

Substituting fish of lesser value for high priced fish such as grouper has become a major problem for restaurants, wholelsalers, and the general public. A method based upon nucleic acid amplification enables clear differentiation between grouper and potential substitutes. The nucleic acid is incubated with a molecular beacon probe thereby allowing detection of the hybridized molecular beacon probe. All grouper, including the fresh market sample, were successfully confirmed as grouper. Several non-grouper samples obtained fresh and frozen from the market were also tested; none were detected as grouper.

Tarnish'd With Ashes And Soot: A Classic Poem’S Dank Corners, John M. Rudy

Interpreting the Civil War: Connecting the Civil War to the American Public

The legend is striking: Clement Clarke Moore, sitting with his children on a Christmas Eve in 1822, reading them a poem he has scrawled out that day, inspired by a winter shopping trip. Little Charity and Mary were likely entranced at six and three. Clement, a one-year-old, and Emily, a newborn, likely weren’t as enrapt by the lilting rhymes.

The poem for Moore’s children found new life a year later, published in a Troy, New York newspaper. And since then, A Visit From Saint Nicholas has been embedded in our culture. [excerpt]

Reid On Olfaction And Secondary Qualities, Jake Quilty-Dunn

Publications and Research

Thomas Reid is one of the primary early expositors of the “dual-component” theory of perception, according to which conscious perception constitutively involves a non-intentional sensation accompanied by a noninferential perceptual belief. In this paper, I will explore Reid's account of olfactory perception, and of odor as a secondary quality. Reid is often taken to endorse a broadly Lockean picture of secondary qualities, according to which they are simply dispositions to cause sensations. This picture creates problems, however, for Reid's account of how we perceive secondary qualities, including odors. Given Reid's insistence that we come to be aware of odors only …

Syrian And Palestinian Syrian Refugees In Lebanon: The Plight Of Women And Children, Lorraine Charles, Kate Denman

Journal of International Women's Studies

The humanitarian crisis resulting from the Syrian conflict is estimated to be the worst so far of this century. The recent influx of refugees has now reached a point where they are equal to one quarter of Lebanon’s population, causing evident strains on its fragile economy and social structure. Syrians in Lebanon have fled from their home to seek safety, however their vulnerability is now in question as women’s and children’s rights continue to be under threat. This paper investigates the plight of Syrian and Palestinian Syrian refugees in Lebanon with an emphasis on women and children. While there are …

"We Thought We Were Playing": Children’S Participation In The Syrian Revolution, Layla Saleh

Journal of International Women's Studies

This article explores the participation of children in the Syrian uprising against Bashar al-Assad. The involvement of children in democratic social movements and regime transitions has not been addressed in the literature, although some works describe the role children can play in making public policy or in the humanitarian domain. I argue that just as the role of women and of university-aged youth was gradually incorporated in the body of research on the social movements and regime transitions, so should the role of children be studied. I then characterize the role of children in the Syrian uprising as a three-stage …

Libya's Implosion And Its Impacts On Children, Lere Amusan

Journal of International Women's Studies

The Arab Spring’s ripple effects on Libya led to the overthrow of Muammar Al-Qaddafi’s government of over four decades. The regime change in Libya was not a smooth adventure. It led to a civil war, which impacted negatively on Libyan children. The seeds of discord that this war sowed in the once considered stable state shall be the focus of this discussion through the employment of descriptive and analytical methods. The contention of this study is that every actor in the civil war disregarded various international treaties that protect children and indigenous peoples during the war. This paper argues that …

Lessons Gleaned From The Political Participation Of Children In Bahrain Uprising, Hae Won Jeong

Journal of International Women's Studies

Reflecting the tension between state sovereignty and human rights, this paper discusses the moral and ethical implications of the political participation and detention of Bahraini children against the backdrop of sectarian geopolitics. Drawing methodological insights from postmodernism, this paper argues that reading of Bahraini children as political subjects are objectified and reified with truth claims, which ascribes them a minoritized status based on age and sect. This paper is interdisciplinary in its approach and is three-pronged: First, it begins by providing a contextual analysis of sectarian politics and dichotomous discourses of national sovereignty and human rights. Secondly, this paper juxtaposes …

Nation, Gender, And Identity: Children In The Syrian Revolution 2011, Manal Al-Natour

Journal of International Women's Studies

This article examines the victimization and role of Syrian children in the Syrian Revolution 2011. I claim that through engaging in a competition to provide a definitive image of the nation, both the regime and the opposition victimize Syrian children. Nevertheless, the art projects undertaken by nonviolence activists have proven to help children heal and to cope with the predicaments brought on them by the crisis. The poetry, paintings, drawings, and songs produced by these children are the best means they have of representing their victimization and their role in the revolution, and communicating their perspectives on the Syrian nation …

Women Lost, Women Found: Searching For An Arab-Islamic Feminist Identity In Nawal El Saadawi’S Twelve Women In A Cell In Light Of Current Egyptian "Spring" Events, Ebtehal Al-Khateeb

Journal of International Women's Studies

Dr. Nawal El Saadawi, an Arab feminist, playwright, novelist, and thinker, has been one of the most controversial literary figures in Arab contemporary literature. In this paper, I examine El Saadawi’s 1984 play Twelve Women in A Cell in light of the ongoing political dissidence that gave birth to the recent Arab Spring and its intricate relation to feminist dissidence. The play published twenty-eight years ago, deals with a bizarre situation that surprisingly and sadly, is still relevant to women’s struggle within Arab-Islamic hegemony. The cell that hosts twelve Egyptian women, in El Saadawi’s play, becomes the Arabic Islamic patriarchal …
