Effect Of Full-Annular Pressure Pulses On Axial Turbine Performance, Mark H. Fernelius

Theses and Dissertations

Pulse detonation engines show potential to increase the efficiency of conventional gas turbine engines if used in place of the steady combustor. However, since the interaction of pressure pulses with the turbine is not yet well understood, a rig was built to compare steady flow with pulsing flow. Compressed air is used in place of combustion gases and pressure pulses are created by rotating a ball valve with a motor. This work accomplishes two main objectives that are different from previous research in this area. First, steady flow through an axial turbine is compared with full annular pulsed flow closely …

An Experimental Analysis Of The Weighted Sum Of Spatial Gradients Minimization Quantity In Active Structural Acoustic Control Of Vibrating Plates, Daniel R. Hendricks

Theses and Dissertations

Active Structural Acoustic Control (ASAC) is a subcategory of the more widely known field of Active Noise control (ANC). ASAC is different from traditional ANC methods because it seeks to attenuate noise by altering the noise producing structure instead of altering the acoustic waves traveling through the air. The greatest challenge currently facing ASAC researchers is that a suitable parameter has not yet been discovered which can be easily implemented as the minimization quantity in the control algorithms. Many parameters have been tried but none effectively attenuate the sound radiation in a way that can be easily implemented. A new …

Effects Of Increasing Temperature And Ocean Acidification On The Microstages Of Two Populations Of Saccharina Latissima In The Northwest Atlantic, Sarah Redmond

Master's Theses

Saccharina latissima (Linnaeus) C.E.Lane, C.Mayes, L.D. Druehl and G.W.Saunders, is the most widely distributed species of kelp in the western North Atlantic, occurring from the Arctic to Long Island Sound. The effects of global climate change on these ecologically and economically important cold temperate species at the southern range of their distribution are unknown. This study investigated the impact of the combined stressors of increased temperature (16, 19, 22, 25 & 28°C) and reduced pH (7.9, 7.8, 7.7, & 7.6) on the gametophyte and juvenile sporophyte stages of sugar kelp populations from Maine and Long Island Sound. Spore germination and …

Social Marketing And California High-Speed Rail: A Framework For Behavioral Change Towards Sustainability, Spenser Dill

Master's Projects and Capstones

In this analytical paper, I advocate for the use of social marketing techniques in a campaign targeted towards Central Valley communities with the primary objective of reducing this population’s opposition to the state’s High-Speed Rail project. A secondary objective is to use this strategy to promote positive attitudes towards sustainable practices in general. The goal is to stimulate a change in regional culture, which will support the behavioral changes needed to protect California’s natural resources and reduce our state’s contribution to climate change. I argue: 1) creating a sustainable transit infrastructure with high-speed rail as its centerpiece will reduce harmful …

Winning Hearts And Minds: Using "Ag-Gag" Outrage And Corporate Rebranding To Achieve A Public Image Makeover For The Animal Rights Movement, Alison J. Spasser

Master's Projects and Capstones

Despite limited legal victories—particularly in the realm of companion animal protections—the animal rights movement has failed to make substantial progress in other focal areas, including the acquisition of increased rights for food animals on factory farms. The public image of the movement has taken a hit in recent years, due in part to effective campaigning by opposing lobbies and corporate entities and in part to self-inflicted damage from failed messaging and tactics. The perceived alignment of animal rights advocacy organizations with extremism and the public distrust of activists leaves the movement in need of a critical public image makeover. However, …

Novel Thermophilic Bacteria Isolated From Marine Hydrothermal Vents, Christine Demko Sislak

Dissertations and Theses

As part of a large study aimed at searching for patterns of diversity in the genus Persephonella along the north to south geochemical gradient of the ELSC, ten novel strains of Alphaproteobacteria were isolated unexpectedly. Using defined media under microaerophilic conditions to enrich for Persephonella from chimney samples collected at the seven vent fields on the ELSC and the dilution to extinction by serial dilution method to purify cultures, a total of ten strains belonging to the Alphaproteobacteria were isolated. Two of these isolates, designate MN-5 and TC-2 were chosen for further characterization and are proposed as two new species …

Enhanced Sonar Array Target Localization Using Time-Frequency Interference Phenomena, Jordan Almon Shibley

Dissertations and Theses

The ability of traditional active sonar processing methods to detect targets is often limited by clutter and reverberation from ocean environments. Similarly, multipath arrivals from radiating sources such as ships and submarines are received at sensors in passive sonar systems. Reverberation and multipath signals introduce constructive and destructive interference patterns in received spectrograms in both active and passive sonar applications that vary with target range and frequency. The characterization and use of interference phenomena can provide insights into environmental parameters and target movement in conjunction with standard processing methods including spectrograms and array beamforming.

This thesis focuses on utilizing the …

Who Owns This Body? Enslaved Women's Claim On Themselves, Loucynda Elayne Sandeen

Dissertations and Theses

During the antebellum period of U.S. slavery (1830-1861), many people claimed ownership of the enslaved woman's body, both legally and figuratively. The assumption that they were merely property, however, belies the unstable, shifting truths about bodily ownership. This thesis inquires into the gendered specifics and ambiguities of the law, the body, and women under slavery. By examining the particular bodily regulation and exploitation of enslaved women, especially around their reproductive labor, I suggest that new operations of oppression and also of resistance come into focus.

The legal structure recognized enslaved women in the interest of owners, and this limitation was …

Sexting Unleashed: The Social Phenomenon According To Youth Sexters, Jessica Marie Mcgraw

Dissertations and Theses

What is missing from academia and society at large is a more holistic picture of youth sexting. Not adequately understanding youth sexting has stunted previous attempts to effectively educate young people on its potential consequences. As such, the social and legal consequences of sexting gone viral have negatively impacted countless individuals. This study offers a preliminary glimpse of the sexting phenomenon by highlighting the experiences of 20 young people. I explore emergent themes regarding the nature of youth sexting as well as the interrelations amongst privacy, relationships, and sexting. Two distinct forms of sexting emerged from participant narratives, opening the …

A Teacher's Guide To Academic Reading: Focusing On The Academic Reading Demands Of Esl Learners, Rebecca Jean Stone

Theses and Dissertations

With over 765,000 English-as-a-second-language (ESL) students studying in the United States, a greater understanding of the academic requirements and demands these students face while studying in the US is needed. Some of the biggest challenges they face include the amount of reading required and the various tasks employed with academic reading. University reading tasks require more than an understanding of the text. These tasks place a strong emphasis on text comprehension, summary, synthesis, and critical analysis. This is problematic as students, especially ESL learners, lack experience with academic tasks, and many additionally struggle with low metacognitive awareness, limited or low …

Evaluating The Effectiveness Of Supplemental Educational Services In Large Texas School Districts, Carlos Lee

Seton Hall University Dissertations and Theses (ETDs)

ABSTRACT

With the need for greater education reform, President George W. Bush and Congress enacted No Child Left Behind (U. S. Department of Education, 2001). The enactment of NCLB was accompanied by additional requirements concerning accountability for student achievement. The search for methods that provide educational enhancements continues through the work of schools and local community members (Hock, Pulvers, Deshler, & Schumaker, 2001). Supplemental Educational Services (SES) are defined as supplementary academic instructional services intended to raise the level of academic achievement of Title I students in schools that have failed to meet federal mandated AYP standards for three consecutive …

This is a thesis conducted qualitatively using the Grounded Theory approach where in-depth interviews were conducted with 12 legal Mexican Americans in order to understand how social media affect Mexican Americans' social identity. This effect was understood by discovering the relationships between social identity theory and integration. Results showed that Mexican Americans felt that social media helped them with their English skills and connected them to their friends and family in Mexico. Mexican Americans were able to use social media to connect to their in-group community, and Mexican American community leaders were able to connect Mexicans to their in-group within …

Mitochondrial Dysfunction And Reactive Oxygen Species In Neurodegeneration, Leah Farina

Honors Theses

Neurodegeneration leads to the loss of normal anatomy and physiology of the neuronal system in a human body. The hallmark of most neurodegenerative diseases is abnormal folding and accumulation of proteins within neuronal cell bodies that is not present in healthy people. These changes in normal protein metabolism often lead to neuronal cell death and failure of the affected regions of the central nervous system. Abnormal protein accumulation may be attributed to dysfunctional mitochondria and damage by reactive oxygen species. In addition to causing altered protein accumulation, dysfunctional mitochondria and an excess of reactive oxygen species also lead to errors …

The Lion & The Ringmaster: Croatia's Accession To The European Union, Jelena N. Bilandzich

Master's Theses

July 1, 2013 marked Croatia's official induction into the European Union. For Croatia this was the culmination of a long negotiation process filled with concessions and challenges. This situation inspired the question of how Croatia's alliance with the EU has affected the state? In order to analyze this relationship the aspects of Croatian identity and sovereignty were explored, in addition to the EU's principles and problems regarding member and candidate states. The evidence found within this investigation came from a number of literary sources ranging from the academic to official government documents. Furthermore, nine interviews were conducted within Croatia, which …

Land Grabs And Implications On Food Sovereignty And Social Justice In Senegal, Joanna Lafrancesca

Master's Theses

This thesis focuses on the case study of Senegal to examine the implications of large- scale land acquisitions on the livelihoods of small-scale farmers. I investigate the diverse perspectives of market enthusiasts, human rights organizations, peasants, the state, and international financial organizations on large-scale land acquisitions. Based on primary research, I argue that the state of Senegal plays an active role in permitting “land grabs” and that they pose a threat to food sovereignty among Senegalese host communities. Lastly, I argue there needs to be a broader understanding of long-term consequences and risks to insure social justice in areas affected …

Between Mobility And Stability: Immigration, Free Trade, And Human Rights In The Context Of The Latino Immigrant, Joseph M. Stosberg

Master's Theses

This work takes a multi-dimensional approach to understanding human rights abuse toward Latino immigrants. It is argued here that the opening up of Mexico and Central American countries to free trade, and the restricted movement across borders has increased human rights abuse toward immigrants. In order to investigate these issues this research looks at: the opening up of Mexico and Central American countries to free trade; a pervasive narrative that portrays the Latino immigrant as a threat; and U.S. immigration policy. I use these respective bodies of literature to guide the discussion of the Latino immigrant experience, from the decision …

The Plight Of Kenyan Domestic Workers In Gulf Countries, Caroline Muthoni Gikuru

Master's Theses

Kenya’s economy remains the regional leader within the East African Community (EAC) and among East African countries at large. However, political instability such as the 2007 post-election violence and the region’s social and political instability trickling into Kenya, have negatively affected the country’s economic growth. To bridge the economic gap, Kenyan women are seeking employment in the domestic service sector in the Gulf Countries, with Saudi Arabia being the most popular destination. At their destination countries, some domestic workers are subjected to various forms of abuse by their employers, leaving the worker without recourse due to the lack of legal …

From Corps To Co-Ops: Are Co-Operatives A Viable Reintegration Strategy For Ex-Combatants?, Patrick Moses Musibi

Master's Theses

From 1989, Disarmament, Demobilization and Reintegration (DDR) programmes have played a major role in peace agreements worldwide. The first United Nations peacekeeping mission with a DDR mandate was ONUCA, (Observadores de las Naciones Unidas en Centroamerica) or the United Nations Observer Group in Central America and involved the reintegration of ex-combatants after the conflict had finished. While the disarmament and demobilization phases of the DDR programs are fairly straightforward events, success in the reintegration phase remains a great challenge. In this thesis I argue that paying closer attention to the challenges facing ex-combatants at an individual level can help in …

Fumarate Inhibits Tnf-Α Release, Megan Kelly

Seton Hall University Dissertations and Theses (ETDs)

Vertebrates utilize two forms of immunity to combat pathogens. Innate immunity is considered the first line of defense that utilizes immediate action and three barriers. Innate immunity responses typically occur within minutes of pathogen exposure resulting in cellular receptor activation and acute pro-inflammatory cytokine release. Inflammatory macrophages engage bacterial endotoxins, including Gram-negative lipopolysaccharide (LPS) and Gram-positive lipoteichoic acid (LTA). And respond by releasing tumor necrosis factor-α (TNF-α). While beneficial for neutralizing acute pathogen exposure, prolonged TNF-α release results in chronic inflammation and tissue damage. In the present study, we examined two methylated derivatives of a citric acid cycle intermediate, fumarate, …

The Role Of Information And Communication Technology In The Acculturation Of Vietnamese Refugees, Khanh A. Tran

Master's Theses

One of the most significant refugee populations in the United States is the Vietnamese. This group initially fled their native country to escape political oppression at the conclusion of the Vietnam War in 1975 and continued to flee in a series of separate waves that continued for more than three decades. As a relatively new immigrant group in the U.S., the Vietnamese still face a variety of challenges as they try to reestablish their lives and adapt in a new cultural environment. Acculturation is a complex process that is influenced by a number of factors. Throughout history, U.S. immigration policy …

Biochemical Assay Optimization And Computational Screening Efforts To Identify Potential Luxs Inhibitors, Keeshia Q. Wang

Master's Theses

Quorum sensing (QS) is a process of coordination of bacterial gene expression in response to cell population. System two QS is regulated by the small signaling molecule autoinducer-2 (AI-2) and is implicated in the infectious behaviors of various bacterial species. AI-2 is biosynthesized from S-ribosylhomocysteine (SRH) by the enzyme LuxS and induces interspecies cell-to-cell communication. Inhibition of LuxS would therefore inhibit interspecies QS. Herein, a search for novel molecular species that will competitively bind with SRH in the LuxS binding site is performed in silico. Computational screening results are then validated in vitro using an optimized LuxS inhibition …
