Cyclotron Resonance In Graphene Heterostructurescyclotron Resonance In Graphene Heterostructures, Billy Jordan Russell

Arts & Sciences Graduate Student Theses and Dissertations

We present observations of cyclotron resonance in graphene Van der Waals heterostructure devices. Such devices provide dramatic improvements in sample quality and allow for ad- vanced electronic control, opening windows on previously inaccessible physics. The design and construction of a dedicated system for the measurement of electronic transport and infrared magnetospectroscopy in microscopic samples of atomically thin materials at cryogenic temperatures is presented. In high-mobility encapsulated monolayer graphene, electron- electron interaction effects are unambiguously observed to impact the interband cyclotron resonance as the Landau level filling factor is varied in a quantizing magnetic field. Additionally, a splitting of transitions involving …

Constitutional Organization Of Local Languages ​​"A Comparative Analytical Study", Bassem Mohsen Nayef Praiseworthy

Uruk Journal of Human Sciences

The drafting of the constitution in the language adopted by the people has become a fait accompli to represent its identity and demonstrate its autonomy and unify its societies. This requires their use of the language with the same art, craft, methodology and standard to preserve them in a way that reaches the people, And in order to reach the content of the Constitution to others committed to it so as not to be difficult to recognize the purpose, whether in terms of the Inclusiveness, or in terms of detailed analysis of its texts, because it is an integral part …

Courting Love: Comedy And Genre In Robene And Makyne, Caitlin Flynn

Studies in Scottish Literature

Observing that little critical scrutiny has been given to Henryson's shorter poems, argues that Henryson's Robene and Makyne challenges genre critics by its "seamlessness ... weaving together of courtly and country, formal and frolicking," and that the two lovers, who "embody the generic confusion marking the formal qualities of the poem," reflect "the comic instability of the generic resonances within the text," pointing to wider trends in Scottish imaginative literature of the period.

The Poetry Of William Forbes Of Disblair (1661-1740), William Donaldson

Studies in Scottish Literature

Arguing that the early 18th century Scottish poet William Forbes has been given too little attention, introduces some of the issues in settling the canon of Forbes's work, and discusses both Forbes's anti-Union political poetry, notably The True Scots Genius, Reviving (1704), and A Pil for Pork-Eaters (1705), and his later dialogue on marriage, Xantippe: or the Scolding Wife (1724), an original development from a Latin dialogue by Erasmus. An appendix gives details of the eleven published poems attributable to Forbes.

Regional Gene Repression By Dna Double-Strand Breaks In G1 Phase Cells, Caitlin E. Purman, Patrick L. Collins, Sofia I. Porter, Ankita Saini, Harshath Gupta, Barry P. Sleckman, Eugene M. Oltz

Open Access Publications

DNA damage responses (DDR) to double-strand breaks (DSBs) alter cellular transcription programs at the genome-wide level. Through processes that are less well understood, DSBs also alter transcriptional responses locally, which may be important for efficient DSB repair. Here, we developed an approach to elucidate the

Working Paper No. 37, The American Opium Trade, Karson M. Pence

Working Papers in Economics

This inquiry seeks to establish that American merchants exacerbated China’s 19th century opium epidemic. Circumventing Britain’s monopoly of Indian opium, three men, Thomas Perkins, John Cushing, and Robert Forbes, played a key role in American consolidation of Turkish opium production. With malice and blatant disregard, numerous Americans pumped tens of thousands of chests of opium into China, creating fabulous riches and incredibly influential familial dynasties while simultaneously destroying the minds and bodies of an untold number of Chinese.

Working Paper No. 42, Commodity Production As An Explanatory Variable In The Outbreak Of The American Civil War, Andrew Pope

Working Papers in Economics

This inquiry seeks to establish that the American South’s comparative advantage in primary commodity production can be identified as an explanatory variable in the outbreak of the American Civil War. In addition, this inquiry seeks to illustrate the positive historical correlation between a state’s reliance on primary commodity production and its propensity to generate extreme outcomes—namely, institutional inequality, conflict, and civil war. Furthermore, this inquiry seeks to demonstrate that civil wars can be primarily understood as a function of a rebelling force’s economic motivations and explores the concept of King Cotton, westward expansion, and the South’s ultimate secession from the …

Working Paper No. 50, Alexis De Tocqueville On American 'Exceptionalism', Zachary Mckinster

Working Papers in Economics

From early settlers to the sophisticated nuances and concerns facing Americans in his time, Alexis de Tocqueville authored a definitive piece on democracy as it emerged and was practiced in 19th century America. This inquiry seeks to establish that Tocqueville’s penetrating insights into the United States in its early decades assisted him in arriving at the notion of what is widely touted as American ‘Exceptionalism’. In the first half of the 19th century Tocqueville travelled widely, seeking to understand this republic and its constitutional emphases upon principles of democracy. Completing his tour, in 1835 Tocqueville published Democracy in America. It …

Protection Of The Child's Psychological Security Under Criminal Legislation (Comparative Study), وسام كاظم زغير

Alustath Journal for Human and Social Sciences

The subject of research: (protection of the child's psychological security under criminal legislation) has a practical significance to guarantee the right of the child to enjoy psychological security away from violence or ill-treatment, since The child is weak at this stage; he cannot defend himself in the face of the dangers to which he is exposed. Moreover, he needs care and concern for his physical and psychological rights, and although there are some provisions in the Iraqi Penal Code No. 111 of 1969, which provides criminal protection, but the protection of his right to psychological security was not within the …

A Microfluidic Platform To Investigate The Mechanism By Which Gdnf Overexpression In Schwann Cells Causes Neuronal Axon Entrapment, Ze Zhong Wang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Twenty million Americans suffer from peripheral nerve injury (PNI) caused by trauma and medical disorders, with approximately $150 billion spent in annual health-care dollars in the United States. Even with proper surgical reconstruction, less than 50% of the patients achieve satisfactory functional recovery. The gold standard surgical repair for long gaps (>3cm) is the autologous nerve graft, despite its disadvantages such as donor site morbidity, risk of infection, and increased cost. Alternative methods, such as acellular nerve grafts (ANA), are ineffective for large lesion gaps because of the lack of cells and regeneration factors. Recent efforts have been focused …

Rhodococcus Opacus Pd630 Genetic Tool Development To Enable The Conversion Of Biomass, Drew Michael Delorenzo

McKelvey School of Engineering Graduate Student Theses & Dissertations

The discovery of fossil fuels facilitated a new era in human history and allowed many firsts, such as the mass production of goods, the ability to travel and communicate long distances, the formation of population dense cities, and unprecedented improvements in quality of life. Alternative sources of energy and chemicals are needed, however, as hydrocarbon reserves continue to deplete and the effects of burning fossils on the planet become better understood. Lignocellulosic biomass is the most abundant raw material in the world and a viable alternative to petroleum-derived products. The pre-treatment of lignocellulose (e.g., thermocatalytic depolymerization, enzymatic hydrolysis, pyrolysis, etc.) …

Contemporary Problems In Aerosol Aggregation And Gelation, Pai Liu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Aggregation of nanoparticles in aerosols is a fundamental phenomenon with important implications to diverse fields ranging from material synthesis to pollutant control. The past few decades have witnessed extensive research on investigating the structure and growth mechanism of aerosol aggregates with sizes spanning across several orders of magnitude. This dissertation focuses on some contemporary problems that remain unaddressed in this topical area. Aerosol aggregates in sub-micron regimes, which are formed via the irreversible collision and aggregation of solid nanoparticle monomers, are fractal-like in their morphology. A mathematical description of this seemingly random structure dates to the seminal works by Forest …

Dynamics And Control In Spiking Neural Networks, Fuqiang Huang

McKelvey School of Engineering Graduate Student Theses & Dissertations

In the brain, neurons (brain cells) produce electrical impulses, or spikes, that are thought to be the substrate of information processing and computation. Through enigmatic processes, these spikes are ultimately decoded into perceptions and actions. The nature of this encoding and decoding is one of the most pervasive questions in theoretical neuroscience. In other words, what are the specific functions enacted by neural circuits, through their biophysics and dynamics? This thesis examines the dynamics of neural networks from the perspective of control theory and engineering. The pivotal concept is that of the normative synthesis of neural circuits, wherein neural dynamics …

Wheelchair Propulsion For Everyday Manual Wheelchair Users: Repetition Training And Machine Learning-Based Monitoring, Pin-Wei Chen

Arts & Sciences Graduate Student Theses and Dissertations

Upper limb pain and injuries are prevalent among manual wheelchair users and can restrict their participation and daily activities. Due to the high repetition and force in wheelchair propulsion, chronic wheelchair propulsion has been linked to the risk of upper limb pain and injury. Prevention of upper limb pain and injury is a high priority in wheelchair-related research. Decades of research in wheelchair propulsion biomechanics have led to clinical practice guidelines (CPG). Unfortunately, a decade after the publication of the CPG, CPG-recommended propulsion is still uncommon. Hence, for the first aim, a randomized controlled trial pilot study with two groups …

The Tortured Pre-History Of Urban Blight: African American St. Louis And The Politics Of Public Health, 1877-1940, Taylor Desloge

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation is a long history of the contested legal and environmental category of blight, especially in its racialized dimensions, in tandem with the African American experience of living in blighted urban spaces and forging a black politics of public health and welfare. Rethinking the conventional view that identifies blight as simply a preoccupation of post-World War II planners, this dissertation relocates its roots in a politics of public health that emerged a hundred years earlier, in the Post-Reconstruction Era, when black migration to the city and the rise of industrial capitalism raised new questions over both the social needs …

Uncovering The Women In Ocean’S Eight: Understanding The Trends Of The Women’S Movement With The Portrayals Of Women In Film, Elyssa Michelle Day

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study seeks for a better understanding of the correlations between major milestones in the women’s movement and how that is reflected onto the silver screen. With the rise of sexual assault allegations against prominent figures in Hollywood, and the growth of the #MeToo movement, we in turn are beginning to see an influx of films being released, and older films being rebooted, with an all-female led cast. One of those all-female film reboots is Ocean’s Eight, a film coming from a male-dominated trilogy and genre. Because of this correlation, the question of whether the narratives within Ocean’s Eight reinforce …

Arbitrary High Order Finite Difference Methods With Applications To Wave Propagation Modeled By Maxwell's Equations, Min Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation investigates two different mathematical models based on the time-domain Maxwell's equations: the Drude model for metamaterials and an equivalent Berenger's perfectly matched layer (PML) model. We develop both an explicit high order finite difference scheme and a compact implicit scheme to solve both models. We develop a systematic technique to prove stability and error estimate for both schemes. Extensive numerical results supporting our analysis are presented. To our best knowledge, our convergence theory and stability results are novel and provide the first error estimate for the high-order finite difference methods for Maxwell's equations.

UNLV Theses, Dissertations, Professional Papers, and Capstones

Vaccination is considered one of the most successful public health achievements of the 20th century. However, with increasing vaccine skepticism emerging over the past decades, there is a threat to the ongoing sustainment of vaccine coverage within all US communities. This study evaluated and compared parents’ sociodemographic factors associated with childhood vaccine decisions. This study is a secondary analysis of 893 parents/guardians, age 18-55 years with child(ren) < 7 years living in the U.S.

Predictive analysis was conducted using multinomial logistic regression modeling was used to examine vaccine decisions (accept, hesitant, and refuse) in relation to parents’ sociodemographic factors. Overall, (66.6%) of parents accepted recommended vaccines, while …

The Retrospective Analysis Of Radionuclides In Banded Coral From The Bikini Atoll, Athena Marie Gallardo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nuclear weapons testing conducted within the Bikini Atoll in the Marshall Islands resulted in local fallout contamination, including long lived isotopes of plutonium (Pu) and uranium (U), within the surrounding environment. The Bikini lagoon provides a continuous source of Pu (239+240Pu) and U (236U) to the Pacific Basin. The rate at which these isotopes are flushed from the lagoon to the ocean is balanced by inputs from remobilization of lagoon sediments. This research will provide a basis for predicting future change in the solubility and export potential of Pu and U in lagoon sediments. This is important to better understand …

Ethnic Power Dominance In A Resource-Rich Sub Saharan African State: An Analysis Of Violent Conflict Accelerators And The Mitigating Influence Of Civil Society In Nigeria, Victor O. Fakoya

UNLV Theses, Dissertations, Professional Papers, and Capstones

My dissertation research explores the impacts of ethno-regional power dominance, trust, and violent conflict in a resources-rich multiethnic, sub-Saharan African state. This dissertation examines the impact that ethnic power dominance has on the relationship between conflict and civil society in a resource rich sub-Saharan African (SSA) nation examined. Relying upon intra-state case study analysis of the socio-political climate in Nigeria, I argue that distrust in the national government, when motivated by ethno-regional cleavages has an accelerating influence on the incidence of conflict. Using cross-national survey data in conjunction with field interview data, this research finds that in the regions where …

Uncovering New Mechanisms Of Cdc34 And Cullin-Ring Activity, Spencer Hill

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ubiquitylation is a cellular regulatory system found in all eukaryotic cells, which has managed to find a role in most pathways imaginable. The system works fundamentally through the ligation of a small protein known as ubiquitin onto a substrate. Depending on the context of the ubiquitin ligation, the substrate can be directed towards a number of cellular fates, the best-studied being degradation of the substrate. While originally thought of as a signal for cellular disposal units to degrade aberrant proteins, we now know that ubiquitin plays a highly nuanced role in cellular epistasis, controlling everything from the cell cycle to …

The Effect Of Pleistocene Glacial - Interglacial Cycles On Patterns Of Genetic Diversity And Differentiation Of Populations Of Leptodactylus Albilabris (White-Lipped Frog) In The Puerto Rican Bank, Andre Nguyen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The historical distributional shifts of various species have been attributed to the glacial-interglacial cycles of the Pleistocene Epoch (2.6 mya – 10,000 ya). Sea level changes caused by Pleistocene glacial-interglacial cycles impacted the total area of landmasses, particularly in island systems. Cooler, glacial periods increased emergent (subaerial) island area via lower sea levels. Adjacent islands may have become connected through emergent land bridges, resulting in a larger subaerial landmass. Warmer interglacial periods led to higher sea levels, which in turn reduced island area, and in some cases, submerged land bridges, fragmenting larger islands into separate, smaller units. The Puerto Rican …

Infection Control: The Nurse's Responsibility, Marisa Francis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Over the last century and a half, infection control measures implemented by nursing staff have continued to evolve, resulting in improved patient outcomes. While this progress is impressive, a decline in rates of hospital acquired infections (HAIs) seems to have slowed, with only a 0.5% decrease in the last seventeen years. Unfortunately, nurses are rarely provided educational support on infection control practices beyond undergraduate and new employee trainings. Meanwhile, the Centers for Disease Control (CDC) is frequently updating their infection control practice recommendations.

The purpose of this project was to observe the current rate of infection control compliance by nurses, …

External Voting In Developing Countries: Strategic Bargaining And The Role Of Remittances, Hafthor Erlingsson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study and numerous prior works have argued that remittances increase the likelihood that states will implement external voting. However, quantitative studies have generally failed to find a relationship between reliance on remittances and the adoption and implementation of external voting. In this study it is argued that the pooling of observations from developed and developing countries as well as autocracies and highly consolidated democracies has altered previous results. Most studies have also not investigated possible non-linearities in the relationship between remittances and external voting. The results of this study illustrate the non-linear influence remittances have on non-autocratic developing countries …

On Muddy Banks: An Ecoethnography Of A River Island Community, Nicholas Baxter

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this study, I examine the relationship between a river and a community. Specifically, I analyze the processes and patterns that organize the nature-society relationship and define the river town of Sabula, IA. To guide my historical and ethnographic analysis, I utilize a co constructionist posture (Rice 2013), which sees culture, community, economy, and physicality as much a product of bio-physical forces as social forces. My aim is to understand how Sabula is conjointly constructed and reveal the nuanced interconnections between human communities and nature through which social and environmental problems play out. My analysis clarifies patterns in residents’ identity …

A Binding Sisterhood Of Transnational Feminism: A Close Look At Iran And Argentina, Bernadette Mary Lazar

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines the impact of transnational feminism in Iran and Argentina. Specifically, it focuses on the role of the diaspora and international communities and their interactions with social movements in these two countries. Although the study of transnational feminism is not a new phenomenon, very little research has been dedicated towards distinguishing the effects and differences in outcomes when either the diaspora or the broader international network is involved. By filling this gap in the literature, this dissertation will shed light on whether the diaspora community, NGOs, or the international community is necessary for success or favorable outcomes in …
