Re-Analysis Of The World Data On The Emc Effect And Extrapolation To Nuclear Matter, Stacy E. Karthas

Honors Theses and Capstones

The EMC effect has been investigated by physicists over the past 30 years since it was discovered at CERN. This effect shows that the internal nucleon structure varies when in the nuclear medium. Data from SLAC E139 and JLab E03 103 were studied with the Coulomb correction and directly compared. The Coulomb distortion had a greater impact on the JLab data due to slightly lower energies and different kinematics. The EMC ratio was found to have a dependence on a kinematic variable, which was removed when Coulomb corrections were applied. The methodology was developed to apply Coulomb corrections, which had …

Forcing Mutual Coherence In Diode Laser Stacks, Jonathan R. Wurtz

Honors Theses and Capstones

This paper will discuss both theoretical and experimental attempts to improve the spatial beam quality of diode laser stacks using an external optical system. An overview and derivation of the mathematics of both the optical system and diode lasers will be discussed. The experimental setup will be presented, as well as the fundamental theoretical and experimental results that suggest the external optical system used for this thesis fails to improve the beam quality of a diode laser stack.

Removal Efficiency Of Water Quality Pollutants In A Wet Detention Basin In Grand Forks, Nd, Abbie Marie Beaudry

Theses and Dissertations

It is hypothesized that the applied sampling techniques, water quality analysis, and statistical analysis predict pollutant removal efficiencies of the project site. Current practices in urban stormwater runoff are the design of systems that limit the developed peak discharge to less than or equal to the peak discharge of the pre-developed conditions. This is many times accomplished with the installation of stormwater retention, detention, or attenuation facilities that store the generated runoff from the drainage area. These are commonly known as structural Best Management Practices (BMPs). The City of Grand Forks, ND (City) implements BMPs into the stormwater management plans …

Goose-Derived Igy: A Potential Therapeutic Antibody For The Treatment Of Infectious Disease, Ashley Louisa Fink

Theses and Dissertations

IgY, the predominate avian antibody isotype, has biochemical properties that make it attractive for a human immunotherapy: IgY does not bind to mammalian Fc receptor (FcR) or rheumatoid factor; IgY does not activate the mammalian complement; and IgY has no heteroagglutinins. Anseriformes (waterfowl, e.g. ducks and geese) produce 2 isoforms of IgY, full length IgY and alternatively spliced IgY lacking the Fc region and a stable equivalent to mammalian F(ab')2 fragment, and the predominate isoform following hyperimmunization. We, and others, have demonstrated that egg-derived avian polyclonal antibodies are prophylactic or therapeutic for a variety of different infectious agents including bacteria, …

Theoretical And Experimental Investigation Of Water And Nanofluid Flow In Channels With Sudden Area Change, Emmanuel Hitimana

Theses and Dissertations

Sudden area expansions and contractions in channels are encountered in numerous engineering applications such as pipeline, cooling systems, and heat exchangers. Over the last several decades, numerous studies have been done on this subject. However, there is still a lack of proper investigations, especially on quantifying the viscous pressure loss at the singularity as a function of flow rate along the channel with abrupt area expansion or contraction.

In this study, the investigation was done on the behavior of static pressure of water and 9.58% volume concentration silicon dioxide nanofluid in channels with sudden area expansion and contraction. The main …

An Experimental Investigation Of The Aerodynamic Losses For An Incident Tolerant Low Pressure Turbine Blade Over Moderate To Low Reynolds Numbers At Engine Representative Mach Numbers, Jonathan Long

Theses and Dissertations

In the interest of reducing airport congestion in the near future, researchers at NASA Glenn Research Facility have envisioned a new civilian transport aircraft which takes off vertically and cruises horizontally at Mach 0.5 using tilt-rotor technology. The engine under development consists of a four stage low pressure (LP) turbine. Many challenges are presented as the engine transitions from 100% shaft speed at takeoff to 54% shaft speed at cruise. The blading in this engine must be designed to optimize fuel efficiency, especially at cruise. The flow conditions in the LP turbine will change significantly from a Reynolds number of …

Participants were asked to read a vignette describing a situation where a child either saw, heard, or was physically injured in an intimate partner violence altercation that took place between his parents. Within abuse exposure condition, the gender of the victim was also varied. Participants were asked to decide the extent to which the situation constitutes child abuse and neglect, as well as how much blame and responsibility should be assigned to each parent involved in the incident. Overall, it was found …

A Collapsar Model For Bright Linear Type Ii Supernovae And Numerical Simulations Of Multiple, Interacting Supernova Remnants, Dean D. Smith

Theses and Dissertations

This dissertation includes two projects. Part one applies the collapsar model to Bright Linear Type II supernovae. The collapsar model is commonly used to explain gamma-ray bursts. In this model, a stellar core collapses to a black hole surrounded by an accretion disk. In addition to the supernova caused by the core collapse, the black hole powers a high energy jet. Shocks within the jet create the gamma ray burst while the jet's later interaction with circumstellar material creates an afterglow. In a Type II supernova, the hydrogen envelope of the star results in a lower energy jet that does …

Educational Leadership & Workforce Development Faculty Publications

This study used panel data regression analysis to evaluate the long-term effects of several measures of U.S. education expenditure on unemployment rates in 50 states and Washington D.C. over 25 years. The data included state-level statistics for fiscal effort, graduation rates, education spending per pupil, gross state product per capita, welfare spending, health spending, political party affiliation, union versus nonunion states, and unemployment rates. Results find that the best way to effectively reduce unemployment is investment in improving the quality of human capital through funding education. Findings specifically conclude that over the long term, investment in human capital through education …

Generating A Characterization Method Utilizing The Visible (0.6-1.0 Μm) Peak Feature To Aid In Identification Of Ordinary Chondrite Parent Bodies, Cassandra Lynne Johnson

Theses and Dissertations

Surveys in the visible to near infrared (VNIR) of main belt asteroids which cut off at the 1 micron wavelength prevent adequate characterization for approximately 2500 asteroids. This project aims at surveying spectral data from RELAB and Gaffey's meteorite datasets utilizing the peak feature located between charge transfer and Band I of 224 ordinary chondrite (OC) samples to analyze the peak position shifts with respect to subtypes H-, L- and LL- to generate a new characterization method. This method may make it possible to unite the datasets between the meteorites and asteroids to further constrain and characterize the OC parent …

Indigenous Peoples And The Jurisgenerative Moment In Human Rights, Kristen A. Carpenter, Angela R. Riley

Publications

As indigenous peoples have become actively engaged in the human rights movement around the world, the sphere of international law, once deployed as a tool of imperial power and conquest, has begun to change shape. Increasingly, international human rights law serves as a basis for indigenous peoples' claims against states and even influences indigenous groups' internal processes of decolonization and revitalization. Empowered by a growing body of human rights instruments, some as embryonic as the 2007 United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP), indigenous peoples are embracing a global "human rights culture" to articulate rights ranging from …

The President And Congress: Separation Of Powers In The United States Of America, Harold H. Bruff

Publications

Although the framers of the Australian Constitution adopted many features of the United States Constitution, they rejected the separation of legislative and executive power in favour of responsible government in a parliamentary system like that of the United Kingdom. In doing so, Australians depended on existing conventions about the nature of responsible government instead of specification of its attributes in constitutional text. The United States Constitution contains detailed provisions about separation of powers, but unwritten conventions have produced some central features of American government. This article reviews conventions developed by Congress that constrain Presidents in the domestic sphere with regard …

Governing By Guidance: Civil Rights Agencies And The Emergence Of Language Rights, Ming Hsu Chen

Publications

On the fiftieth anniversary of the Civil Rights Act of 1964, this Article asks how federal civil rights laws evolved to incorporate the needs of non-English speakers following landmark immigration reform (the 1965 Hart-Cellar Act) that led to unprecedented migration from Asia and Latin America. Based on a comparative study of the emergence of language rights in schools and workplaces from 1965 to 1980, the Article demonstrates that regulatory agencies used nonbinding guidances to interpret the undefined statutory term "national origin discrimination" during their implementation of the Civil Rights Act of 1964. Their efforts facilitated the creation of language rights, …

Race To Incarcerate: Punitive Impulse And The Bid To Repeal Stand Your Ground, Aya Gruber

Publications

Stand-your-ground laws have come to symbolize, especially for many in the center-to-left, the intense racial injustice of the modern American criminal system. The idea now ingrained in the minds of many racial justice-seekers is that only by narrowing the definition of self-defense (and thereby generally strengthening murder law) can we ensure Trayvon Martin's death was not in vain. However, when the story of Martin's killing first appeared on the national stage, the conversation was not primarily about the overly lenient nature of Florida's self-defense law. It was a multi-faceted dialogue about neighborhood warriors, criminal racial profiling, and especially the racially …

Murder, Minority Victims, And Mercy, Aya Gruber

Publications

Should the jury have acquitted George Zimmerman of Trayvon Martin's murder? Should enraged husbands receive a pass for killing their cheating wives? Should the law treat a homosexual advance as adequate provocation for killing? Criminal law scholars generally answer these questions with a resounding "no." Theorists argue that criminal laws should not reflect bigoted perceptions of African Americans, women, and gays by permitting judges and jurors to treat those who kill racial and gender minorities with undue mercy. According to this view, murder defenses like provocation should be restricted to ensure that those who kill minority victims receive the harshest …

These materials also had good thermal stabilities up to 350° C. The BET …

Three‐Dimensional Brain Mri For Dbs Patients Within Ultra‐Low Radiofrequency Power Limits, Subhendra N. Sarkar, Efstathios Papavassiliou, David Hackney, David Alsop, Ananth Madhuranthakam, Ludy Shih, Reed Busse, Susan Laruche, Rafeeque Bhadelia

Publications and Research

Background: For patients with deep brain stimulators (DBS), local absorbed radiofrequency (RF) power is unknown and is much higher than what the system estimates. We developed a comprehensive, highquality brain magnetic resonance imaging (MRI) protocol for DBS patients utilizing three-dimensional (3D) magnetic resonance sequences at very low RF power. Methods: Six patients with DBS were imaged (10 sessions) using a transmit/receive head coil at 1.5 Tesla with modified 3D sequences within ultra-low specific absorption rate (SAR) limits (0.1 W/kg) using T2, fast fluid-attenuated inversion recovery (FLAIR) and T1- weighted image contrast. Tissue signal and tissue contrast from the low-SAR images …

Self-Reliance Beyond Neoliberalism: Rethinking Autonomy At The Edges Of Empire, Karen Hébert, Diana Mincyte

Publications and Research

Across scholarly and popular accounts, self-reliance is often interpreted as either the embodiment of individual entrepreneurialism, as celebrated by neoliberal designs, or the basis for communitarian localism, increasingly imagined as central to environmental and social sustainability. In both cases, self-reliance is framed as an antidote to the failures of larger state institutions or market economies. This paper offers a different framework for understanding self-reliance by linking insights drawn from agrarian studies to current debates on alternative economies. Through an examination of the social worlds of semisubsistence producers in peripheral zones in the Global North, we show how everyday forms of …

Plastic Deformation Investigation Of High Energy Input Friction, Tao Yan

Dissertations (1934 -)

In this dissertation, plastic deformation of friction surfaces under high energy input is investigated. The plastic deformation of the friction surface and subsurface was studied and models were established to estimate deformation.

In order to calculate the plastic deformation at friction surface, an algorithm based on Ramberg-Osgood relationship was generated, and a single material model was developed based on this algorithm. Work hardening caused by plastic deformation and thermal softening caused by elevated temperature were considered in the model. To validate the model, an apparatus was designed to perform friction tests under different conditions. A special steel specimen with a …

Ventral Tegmental Area Regulation Of Stress-Induced Reinstatement Of Cocaine-Seeking Behavior, Jordan Michael Blacktop

Dissertations (1934 -)

No FDA approved medications currently exist for the prevention of drug craving, drug seeking, and relapse to cocaine use. Stress is a major factor in causing relapse in cocaine dependent individuals. Cocaine use is positively correlated with stress-induced craving and relapse outcomes. Corticotropin-releasing factor (CRF) is a 41-amino acid neuropeptide that plays an important role in the stress response and in the reinstatement rodent model of stress-induced relapse. CRF is released during stress in brain regions associated with the effects of drugs of abuse, notably the ventral tegmental area (VTA). This dissertation addresses key unknown mechanisms behind drug-induced neuroplasticity and …

I Cheat Because I Can: Power, Sexism And Approval Of Infidelity, Teni Davoudian

Dissertations (1934 -)

This study examined the moderating role of ambivalent sexism in the relationship between power and approval of infidelity. College students were randomly assigned to high- and low-power conditions and completed measures assessing their perceived power, endorsed sexism toward men and women, and approval of their own possible infidelity. It was hypothesized that the association between perceived power and permissive attitudes toward infidelity would vary according to participants' endorsement of hostile and benevolent sexism. The hypotheses were partially supported, and the results revealed the importance of both participant gender and sexism as predictors of attitudes toward infidelity. Hostile sexism toward men …

Dissertations (1934 -)

ABSTRACT

GENERATION OF DIVERSE MOLECULAR COMPLEXITY

FROM CYCLOOCTATETRAENE

Mohamed F. El Mansy, B.Sc, M.Sc.

Marquette University, 2014

The use of simple hydrocarbons as starting materials for the synthesis of complex molecules relies on efficient methods for oxidation, functionalization or rearrangement. For example, various researchers have explored cyclopentadiene or cycloheptatriene as precursors for the preparation of a wide variety of drug candidates, natural products and synthetic products. The purpose of this research is to explore methods to transform the simple hydrocarbon, cyclooctatetraene (COT) into complex target molecules.

Tricarbonyl (cyclooctatetraene)iron, readily prepared from COT, reacts with a variety of electrophiles to form …

Dangerous Knowledge? Morality And Moral Progress After Naturalism, Daniel Diederich Farmer

Dissertations (1934 -)

From the perspective of at least some of our valuing practices, the advance of the sciences can seem to constitute a threat. The question I take up in this dissertation is whether or not naturalism--understood as the picture of the world and of ourselves bequeathed to us by the sciences--should be understood as a threat to our moral practices, to moral living. On the account I defend, the knowledge we gain from empirical inquiry need not undermine moral living in toto, although a naturalistic mindset does raise some possibly dangerous questions for particular inherited moral norms and ideals.

In defense …

A Feminist Perspective On Listening To Women: Birth Stories Of Vaginal Birth Following Previous Cesarean Delivery, Elizabeth Hill-Karbowski

Dissertations (1934 -)

Women's perspectives of their experiences are important, and worthy of study. However, there have been no qualitative comparative investigations of vaginal birth after cesarean (VBAC) experiences of American women using their birth stories as data. Furthermore, there have been no studies where women's experiences of cesarean have been compared with their own subsequent VBAC.

The purpose of this study was to gain insight into the comparative experience of VBAC and cesarean, valuing women and their experiences through the use of a feminist research perspective. By contributing new and valuable insight into an area of research that has been identified as …

Parent And Family Outcomes Of An Empirically Validated Social Skills Intervention For Adolescents With Autism Spectrum Disorders, Jeffrey Scott Karst

Dissertations (1934 -)

Past research has indicated that raising a child with an Autism Spectrum Disorder (ASD) is associated with increased parenting stress, decreased parenting self-efficacy, and increased family distress. While ASD therapies often include significant parental involvement and are typically time-intensive and expensive, studies of ASD treatment have not widely evaluated the impact of treatment on caregivers or the family. There is evidence that successful long-term treatment outcomes are dependent on healthy systemic functioning, and thus it is important to understand how any particular treatment adjunctively affects parents and the family system. The Program for the Education and Enrichment of Relational Skills …

Love For God And Earth: Ecospirituality In The Theologies Of Sallie Mcfague And Leonardo Boff, Rebecca A. Meier-Rao

Dissertations (1934 -)

This dissertation examines the theologies of North American Ecofeminist Sallie McFague and Latin American liberation theologian Leonardo Boff in order to answer the question - What are the features of a Christian spirituality capable of helping people to clear vision, transformation and hope in this time of socio-ecological crisis? In the sixth chapter I also briefly engage the work of Carmelite contemplative Constance FitzGerald, as she both reinforces and deepens the theologians' answer to the above question.

The dissertation begins with a short explanation of the interlocking ecological and social crises, and offers a basic understanding of Christian spirituality as …
