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 …

A Revision Of Power: Religion In Fionn Mac Colla’S And The Cock Crew, Brooke Mclaughlin Mitchell

Studies in Scottish Literature

Discusses the treatment of the central character, the Gaelic-speaking minister Maighstir Sachairi, in And the Cock Crew (1945), by Fionn Mac Colla (Thomas Donaldson, 1906-1975), a historical novel about the Highland clearances(the evictions of the local crofting inhabitants in the north of Scotland to make way for sheep-farming), and argues (1) that, although the novel condemns the Presbyterian clergy for colluding in the evictions and preaching submission to those evicted, Mac Colla's novel is deeply imbued with the Calvinism it might seem to reject, and (2) that the central scene, a debate between Sachairi and a Gaelic bard, is structured …

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.

‘I Am Just As Typically Scottish’: G.S. Fraser As Scottish Poet, Richie Mccaffery

Studies in Scottish Literature

Discusses the poetry and poetic career of G. S. Fraser (1915-1980), both in the 1940s when he was regularly identified as a Scottish poet, and later in his life, arguing that the hostility of Scottish critics to his poetry in the 1950s (when he also built a substantial reputation as a London-based critic and reviewer) was unjustified, leading to the neglect of his substantial and continuing poetic achievement, and encouraging too narrow a definition of Scottish poetry.

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

Performance Modeling Of Supercritical Carbon Dioxide Zigzag-Channel Printed Circuit Heat Exchangers, Katrine Birgitte Bennett

UNLV Theses, Dissertations, Professional Papers, and Capstones

Supercritical carbon dioxide (sCO2) is currently being studied as the working fluid in power producing Brayton cycles due to its excellent physical and thermodynamic properties, especially near the critical point. Printed circuit heat exchangers (PCHEs) are being considered for use as condensers and recuperators for this purpose due to their high strength and compact designs. Many experimental and numerical studies are being conducted to characterize and optimize sCO2 PCHE operation and develop correlations to describe their thermal-hydraulic performance. Additionally, a few experimental and numerical structural assessments of these PCHEs have been conducted, but all have been somewhat limited due to …

Landscape Scale: Inter- And Intraspecific Variation In Plant Interactions Along A Stress Gradient In The Sheep Range Of Nevada, Jordan Dowell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Impending threats to shrubland ecosystems, posed by climate change, necessitate niche modeling efforts to project vegetation range shifts. However, efforts often remain unguided by individual-scale interspecific plant interactions. The stress gradient hypothesis posits that facilitation should increase in areas of high abiotic stress, only if the individuals are able to ameliorate the surrounding area via functional traits. The Sheep Range of Nevada was used to assess the role of functional traits as predictors of plant association. Larrea tridentata, Coleogyne ramosissima, and Artemisia nova were selected as shrubs with variable life history strategies and ranges in order to identify general patterns …

Assessing The Morphology Of Vesicles In Inhibitory Symmetric Synapses In Safety And Fear Conditions In The Rat Lateral Amygdala, Valerie Kress

Honors Scholar Theses

There is a significant lack of research on vesicle morphology in inhibitory synapses in the rat lateral amygdala. Published research focuses heavily on excitatory synapses in different parts of the rat brain and even this research rarely focuses on the different vesicle types in axons. It is reported that in these axons, synaptic vesicles traditionally contain neurotransmitters while small dense core vesicles contain active zone proteins and large dense core vesicles contain neuropeptides. This study aims to find correlations between vesicle morphology, location, contents, and potential function of each of the different types of vesicle in inhibitory axons.

Finding A Viable Neural Network Architecture For Use With Upper Limb Prosthetics, Maxwell Lavin

Master of Science in Computer Science Theses

This paper attempts to answer the question of if it’s possible to produce a simple, quick, and accurate neural network for the use in upper-limb prosthetics. Through the implementation of convolutional and artificial neural networks and feature extraction on electromyographic data different possible architectures are examined with regards to processing time, complexity, and accuracy. It is found that the most accurate architecture is a multi-entry categorical cross entropy convolutional neural network with 100% accuracy. The issue is that it is also the slowest method requiring 9 minutes to run. The next best method found was a single-entry binary cross entropy …

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 …

Corrosion-Resistant Non-Carbon Electrocatalyst Supports For Proton Exchange Membrane Fuel Cells, Cheng He

McKelvey School of Engineering Graduate Student Theses & Dissertations

Proton exchange membrane fuel cells (PEMFCs) are a promising portable power source due to their low operating temperature, minimal pollutant generation and fast startup. However, several challenges remain concerning lifetime, reliability, and cost. A critical issue is PEMFC component durability. Platinum supported on high surface area carbon has been one of the most widely used electrocatalysts in PEMFCs. However, carbon corrosion over the course of normal PEMFC operation occurs due to the relatively low standard electrode potential for the carbon dioxide/carbon redox couple (0.207V vs. standard hydrogen electrode). Considering this challenge, it is imperative to identify alternative support materials to …

Gender Differences In Early Communication, Language Acquisition And Development: A Descriptive Study, رشا عبد الرضا سعيد, رشا عبد المنعم عزيز

Alustath Journal for Human and Social Sciences

Parents pay a significant attention to the first words children utter. However, first words are not the actual beginning of communication. Much earlier, babies begin to communicate their feeling via making eye contact, pointing, crying, squealing, and other gestures. Furthermore, they perceive language earlier than making others understand them. The aim of this paper is to tackle the variations between the two sexes starting from the stages of language acquisition in normal children, the differences between the two genders in language vocalization within each stage. Next, the distinctions in acquiring a particular communicative competence and the causes behind this difference …

Forgiveness Of University Students Exposed To Traumatic Stress, سعد سابط العطراني, مها صائب رشيد

Alustath Journal for Human and Social Sciences

The current research problem stems from the fact that the researchers are aware that our contemporary life is full of painful events that have affected various groups of society, including "university students", and involving them in social and cognitive challenges; hence it was more influential for them since it is fitted to their age stage, and clarifies the future prospects for them. Moreover, they respond to the surrounding variables more than the other categories do, and that may affect negatively their academic performance. Therefore, the current research aims to identify the level of forgiveness of university students exposed to traumatic …

Aggression In August Wilson’S King Hedley Ii, Asma’A Mohannad Saad, Muthanna Mohammad Sultan

Alustath Journal for Human and Social Sciences

The need for investigating the stereotypical image of the African American males as aggressive, criminal individuals brings this research to address this sensitive issue. But the stereotypes of the African American have drawn the attention of many black writers and psychiatrists who tried to dismantle these images by revealing the social, psychological, and socioeconomic factors which contribute in this phenomenon. This paper highlights the reasons that drive the black males to adopt aggression through analyzing August Wilson’s King Hedley II (1999). In this play, Wilson portrays the widely spread aggression and its negative consequences. He also goes a step further …
