Imaging The Subsurface In Eastern Part Of Lake Chesterfield Using A Combination Of Geophysical Tools, Jiawei Li

Masters Theses

"The Lake Chesterfield North Dam in Wildwood city, Missouri has been leaking, more or less continuously since the dam was constructed in 1986 despite mitigation efforts in 1988, 1994, 1995, 2004, and 2005. Neither the grouting efforts in 1988, 1994, 1995, 2004 or 2005, nor the placement and rehabilitation of an impervious clay liner in 2005 has solved the problem. Indeed, in June of 2017, the water level in Lake Chesterfield dropped at an alarmingly rapid rate.

Prior to authorizing additional mitigation work, the Lake Chesterfield Home Owners Association (LCHOA) decided to acquire geophysical data across the dry lake bed. …

Hydraulic Fracture Design Optimization For Nubian Sandstone Formation In Libya, Housameddin Mohamed Sherif

Masters Theses

There is growing interest in developing unconventional oil and gas reserves in Libya, such as the tight portions of the Nubian sandstone.

Well-X7 is a development well drilled to a TD of 13,005' penetrating the Upper Nubain Sandstone (UNSS) at 12,122'-12,207' and the Lower Nubain Sandstone (LNSS) at 12,524'-12,880' KB. Based on open hole logs, the UNSS has 71 ft of net pay and the LNSS was found to have 295 ft of net pay. Openhole logs also showed low permeabilities of 2.5 and 3 md for the UNSS and LNSS, respectively. The well was initially perforated in both zones …

Entrada: Slavery, Religion And Reconciliation, Bill Piatt

Faculty Articles

Each year, Santa Fe, NM celebrates a Fiesta. One component, the Entrada, celebrate the "peaceful" re-conquest of the Indigenous people by the Spanish colonizers. Controversy has arisen in recent years as activists challenge the memorialization of a tradition that they feel represents slavery and brutality. Linking their struggle to recent efforts to remove memorials to the Confederacy, they have sought to physically block the re-enactment, leading to arrests, collateral conflict, and the threat of future violence. How do we move forward as a society with the legacy of slavery that built this region and country: This article examines the historical, …

Prosecuting The War On Terror In The Trump Administration: The Trump Doctrine: Is There Really A New Sheriff In Town, Jeffrey F. Addicott

Faculty Articles

After one full year in office, it is time to examine the actions taken by the Trump Administration in light of its legal and policy structures for dealing with the War on Terror and the companion problem of radical Islamic terrorism-both the domestic and international threat. In this context, two general concepts bear examination. First, is there a significant change in the Trump Administration from the policies of the Bush and Obama Administrations vis a vis prosecuting the War on Terror and dealing with domestic jihadists? Second, has the Trump strategic vision and attendant actions contributed in any significant way …

Of Brutal Murder And Transcendental Sovereignty: The Meaning Of Vested Private Rights, Adam J. Macleod

Faculty Articles

The idea of vested private rights is divisive; it divides those who practice law from those who teach and think about law. On one side of the divide, practicing lawyers act as though (at least some) rights exist and exert binding obligations upon private persons and government officials, such that once vested, the rights cannot be taken away or retrospectively altered. Lawyers convey estates in property, negotiate contracts, and write and send demand letters on the supposition that they are specifying and vindicating rights, which are rights not as a result of a judgment by a court in a subsequent …

Central Hypoventilation: A Rare Complication Of Wallenberg Syndrome, Keithan Sivakumar Md, Mba, Manveer Garcha, Dev Mehta, Megan Leary Md, Hussam A. Yacoub Md

Department of Medicine

Central alveolar hypoventilation disorders denote conditions resulting from underlying neurologic disorders affecting the sensors, the central controller, or the integration of those signals leading to insufficient ventilation and reduction in partial pressures of oxygen. We report a patient who presented with a left lateral medullary ischemic stroke after aneurysm repair who subsequently developed a rare complication of CAH. Increased awareness of this condition’s clinical manifestations is crucial to make an accurate diagnosis and understand its complications and prognosis.

Death During Exercise Testing In A Patient With Asymptomatic Severe Aortic Stenosis, Mahek Shah Md, Anuraj Sudhakaran, Baburaj Aparna, Muhammad Qasim Md, Brijesh Patel Md, Lohit Garg Md, Bruce Feldman Do

Department of Medicine

Introduction: Patients with symptomatic severe aortic valve stenosis (AS) experience short and long-term survival benefit with aortic valve replacement (AVR). Among patients with asymptomatic severe AS (ASAS) current guidelines recommend exercise stress testing (ETT) as a safe and effective method to risk stratify patients and to assist with the timing of AVR. We discuss the course of disease in AS, review the role of ETT and express concerns about the safety of performing stress tests in asymptomatic patients with severe AS. Case Report: We describe the case of a 69-year-old male with left bundle branch block and ASAS who underwent …

Presenting A Critical Perspective On “Economic Efficiency” In Law And Economics Courses, Gregory S. Crespi

SMU Law Review

“Law and Economics” courses are sometimes criticized for inadequately explaining the normative criterion of “economic efficiency” and then applying this criterion throughout the course in a superficial and biased manner that pejoratively labels most governmental market interventions and wealth redistribution measures as inefficient. These criticisms have merit, and in this article I point out a number of conceptual problems, empirical difficulties, and normative shortcomings of the economic efficiency criterion that students need to understand in order to be able to effectively counter policy arguments that rest upon dubious efficiency assessments.

The eight specific shortcomings of the economic efficiency criterion that …

The Decline Of Anglo-American Civil Jury Trial Practice, William V. Dorsaneo Iii

SMU Law Review

This article provides a brief historical explanation of the role that juries have played in Anglo-American civil trial practice. In doing so, the article documents the rise and fall of jury trial practice as a mechanism for resolving civil disputes in both England and America. The article explains how the modern rules of procedure and procedural statutes promote resolving disputes through pretrial litigation procedures at the expense of resolving disputes by jury trial.

The article begins with a description of the use of juries in England at the end of the twelfth century and continues until the near disappearance of …

Rethinking Powers Of Attorney In Real Estate Transactions, Julia Patterson Forrester Rogers

SMU Law Review

The Uniform Power of Attorney Act, adopted in 2006, was designed to address the divergence of various states from the original uniform act and to address problems identified by attorneys practicing in the area. One such problem was the refusal of parties to accept powers of attorney—although a client might execute a durable power of attorney as part of an estate plan to avoid a guardianship, parties would refuse to deal with the agent, thus necessitating a guardianship proceeding. The Uniform Act has now been enacted in some form in more than half of the states, including Texas. The author …

The Enforceability Of Consent-To-Assign Provisions In Texas Oil And Gas Leases, T. Ray Guy, Jason Wright

SMU Law Review

Oil and gas leases are unique instruments that, on their face, appear to be contracts or traditional landlord–tenant leases. Indeed, landowners often desire to have them treated as such by including provisions giving a lessor power to limit or control any assignment of the lease. Typically, this takes the form of a consent-to-assign provision seen in many types of ordinary contracts and leases. In Texas, however, an oil gas lease actually conveys a fee simple property interest; and property law, far more than contract or landlord–tenant law, greatly disfavors any restraint that acts to restrict the free transferability (or “alienation”) …

Richard Posner: A Class Of One, Robert C. Farrell

SMU Law Review

Judge Richard Posner, best known for his contributions to the field of law and economics, has also made an outsized contribution to another area of the law—the equal protection class-of-one claim. By some combination of happenstance and design, Posner was able to shape the class-of-one doctrine even where his views were inconsistent with Supreme Court precedent. The Supreme Court’s initial exposition of the doctrine had identified an equal protection violation when there was intentionally different treatment of similarly situated persons without a rational basis for the difference in treatment. Posner insisted that this language included within it a requirement that …

Policing Narrative, Tal Kastner

SMU Law Review

Counter narrative, a story that calls attention to and rebuts the presumptions of a dominant narrative framework, functions as an essential tool to reshape the bounds of the law. It has the potential to shape the collective notion of what constitutes legal authority. Black Lives Matter offers a counter narrative that challenges the characterization of the shared public space, among other aspects of contemporary society, as the space of law. Using the concept of necropower—the mobilization and prioritization of the state’s power to kill—I analyze the contested physical and conceptual space of law exposed by the counter narrative of Black …

“Heal Thyself.”—An Argument For Granting Asylum To Healthcare Workers Persecuted During The 2014 West African Ebola Crisis, Bethany Echols

SMU Law Review

This article argues for a change in United States asylum policy at a time when change is needed most. Those seeking asylum must prove that they fear persecution in their home country based on one of five protected categories and that their government is the persecutor or is unable to control the actions of the persecutors. Multiple articles have recognized that the “particular social group” is the most difficult category of asylum seeker to analyze. Not only do the standards for particular social groups (PSGs) vary among circuit courts, but judicial consistency is lacking.

This article focuses on a particular …

Preparation And Antimicrobial Activity Of Caprylic Acid Emulsion For Food Coating, Raweewan Bunyovimonnat

Chulalongkorn University Theses and Dissertations (Chula ETD)

Antimicrobial food coating is the interesting method for food preservation, especially in fruits and vegetables. Previous studies have been reported that the caprylic acid had the antimicrobial activity against a variety of microorganisms. However, little research has been conducted on the use of caprylic acid in the form of food coatings. Therefore, this study aims to determine the optimum conditions for the caprylic acid emulsion preparation and to evaluate the antimicrobial activity of the emulsion, including the effect of food coatings with caprylic acid emulsion on physical properties and microbial growth inhibition. Emulsions containing 4% w/v caprylic acid (oil) and …

Extraversion And Person-Environment Fit: Towards Consideration Of Jungian Theory In Organizational Psychology, Nicholas Rosemarino

Theses and Dissertations

Historically, the field of Industrial/Organizational (I/O) Psychology has relied on the Big 5 taxonomy of personality. The purpose of this study was to examine the value of a Jungian conception of extraversion in the context of the relationship between the physical work environment and person-environment (PE) fit. The MBTI and the NEO-IPIP, representing a Jungian and a taxonomic conception of personality, respectively, were hypothesized to predict the within-person relationship between extraverted environment and PE fit. PE fit was hypothesized to predict perceived satisfaction and perceived performance. To examine these hypotheses, 110 participants were recruited from Mturk and responded to 18 …

Developing An Automated System For Supporting Strut Arrangement In Deep Excavation, Pisal Nov

Chulalongkorn University Theses and Dissertations (Chula ETD)

In strut arrangement, current software could detect the constructible problems like clashes. However, this software had some limitations including (1) unable to visualize all clash occurrences on each strut, (2) unable to distinguish between occurrence and non-occurrence of the clash, and (3) unable to check tolerance and spacing problems. Thus, the strut arrangement was still an inefficient process. The research objective was to develop an automated system for supporting strut arrangement in deep excavation. In the methodology, an in-depth interview was conducted to collect the information and knowledge of strut arrangement and analyzed with transcription analysis. This information and knowledge …

Characterization Of Graphene Grown By Direct Liquid Injection Cvd Method With N2 Carrier Gas, Taworn Intaro

Chulalongkorn University Theses and Dissertations (Chula ETD)

We have studied the graphene growth on copper (Cu) foil substrate by direct-liquid-injection chemical vapor deposition (DLI-CVD). Cyclohexane (C6H12) and N2 were used as a liquid carbon precursor and carrier gas, respectively. Structural and electrical properties of graphene were characterized various techniques. Before the growth of graphene, optimization of Cu foil surface was performed as follows by: (i) etching by hydrochloric (HCl) acid to eliminate impurities and copper oxide on the Cu foil surface, then, (ii) electro-polishing process was used to remove the rolling lines and improve the surface roughness, and (iii) thermal annealing treatment was done to increase grain …

Rheology, Morphology And Electronic Properties Of Hybrid Copper Organic Decompose Conductive Ink, Chaiwat Klaewwigkij

Chulalongkorn University Theses and Dissertations (Chula ETD)

Hybrid Metal-Organic Decomposition (HMOD) inks containing alkanol amines copper complex solution with fine copper particles show high potential for flexible printed electronics application. Conductive patterns are fabricated from HMOD inks by screen printing onto a polyimide substrate. This work studies the effects of co-solvent, copper particles loading, and viscosity of the inks on properties of the conductive patterns obtained. Firstly, the effects of co-solvent related to the stability of the HMOD inks and the impact of preparation time related to the crack of the conductive pattern are examined. The HMOD inks are prepared from copper formate (CuF), and alkanol amines …

Effect Of Non-Hermiticity On Adiabatic Elimination In Coupled Waveguides, Rahman Sharaf, M. Dehghani, Hamidreza Ramezani

Physics & Astronomy Faculty Publications

We investigate the influence of non-Hermiticity on the adiabatic elimination in coupled waveguides.We show that although the total norm of the system is not conserved in parity-time symmetric phase, the dark state intensity remains constant. However, in broken phase the eliminated waveguide loses its darkness, i.e., its field amplitude starts increasing. In both exact and broken phases, the effective Hamiltonian derived from the adiabatic elimination condition describes the dynamics of all states except the dark state. Specifically, it cannot predict the amplification in the intensity of the dark state. Our results can strengthen the control of the dynamics in cavities …

Block Copolymer Elastomer With Graphite Filler: Effect Of Processing Conditions And Silane Coupling Agent On The Composite Properties, Denis M. Panaitescu, Raluca Augusta Gabor, Cristian Andi Nicolae, Anca Constantina Parau, Catalin Vitelaru, Valentin Raditoiu, Mircea Chipara

Physics & Astronomy Faculty Publications

The control of morphology and interface in poly(styrene-ethylene/butylene-styrene) (SEBS) composites with graphitic fillers is extremely important for the design of piezoresistive sensors for body motion or flexible temperature sensors. The effects of a high amount of graphite (G) and silane coupling agent on the morphology and properties of SEBS composites with anisotropic mechanical properties are reported. The physical and chemical bonding of silane to both G and SEBS surface was proved by EDX and TGA results; this improved interface influenced both the thermal and mechanical properties of the composite. The vinyltriethoxysilane (VS) promoted the formation of char residue and, being …

Identification And Mitigation Of Narrow Spectral Artifacts That Degrade Searches For Persistent Gravitational Waves In The First Two Observing Runs Of Advanced Ligo, P. B. Covas, A. Effler, E. Goetz, P. M. Meyers, A. Neunzert, M. Oliver, B. L. Pearlstone, Volker Quetschke, Karla E. Ramirez, Darkhan Tuyenbayev

Physics & Astronomy Faculty Publications

Searches are under way in Advanced LIGO and Virgo data for persistent gravitational waves from continuous sources, e.g. rapidly rotating galactic neutron stars, and stochastic sources, e.g. relic gravitational waves from the Big Bang or superposition of distant astrophysical events such as mergers of black holes or neutron stars. These searches can be degraded by the presence of narrow spectral artifacts (lines) due to instrumental or environmental disturbances. We describe a variety of methods used for finding, identifying and mitigating these artifacts, illustrated with particular examples. Results are provided in the form of lists of line artifacts that can safely …

Translinguality And Disciplinary Reinvention, Bruce Horner

Faculty and Staff Scholarship

Dominant narratives of disciplinarity that WAC/WID confronts conflate disciplines with departments and material institutional structures, such as departments and professional organizations—what is here called “departmentality.” The relative autonomy of disciplinarity from departmentality means that challenges to foundational concepts of disciplines are in fact normal to disciplinary work and do not threaten the material institutional structures associated with those disciplines, as illustrated by the history of challenges to foundational disciplinary concepts of basic writing and second language acquisition carried out in disciplinary writing. The relative autonomy of disciplinarity enables us to accept the legitimacy of the challenges translingual theory poses to …
