Removal Capabilities Of Zeolite And Zero Valent Iron With High-Level Waste Tank Radionuclides And Metals: Cesium, Strontium And Chromium, Colette R. Towles

UNLV Theses, Dissertations, Professional Papers, and Capstones

High level nuclear waste (HLW) has been disposed for temporary storage in underground steel tanks at the Department of Energy Nuclear sites. For example, at the Hanford Site, WA, and Savannah River Site (SRS), SC, HLW account for eighty-eight million gallons (Mgal) and 450 million Curies (MCi) of radioactivity. In the early nuclear activity at Hanford, the waste was discharged to single-shell steel tanks, and the lack of secondary containment allowed leaks, contaminating soil and groundwater. Despite tremendous efforts to stabilize the liquid waste at nuclear sites, treatment is complex, costly, and time-consuming; therefore, HLW may have to be stored …

Density-Driven Investigations Of Ruthenium Binary Compounds Rux2 (X = O, S, N), Melanie White

UNLV Theses, Dissertations, Professional Papers, and Capstones

Exploration and fine-tuning of the energy landscape of materials can be accessed by means of changes in material density, a key principle of high pressure research. Density-driven changes impact variations in oxidation states and coordination numbers for the element constituents of a compound. Pressure-induced modification of intrinsic density can promote the formation of new materials, variations in physical properties, and transformations in crystallographic symmetry. With this as our foundation, we focus on ruthenium binary compounds - altering the anion species to change electronegativity while probing pressure and temperature effects. This led us to the present study of ruthenium oxide RuO2, …

Container Runtime Vulnerability Mitigation Using User Namespace Isolation, Alexander Edsell

Electronic Theses, Projects, and Dissertations

Although containers have revolutionized application deployment by allowing for rapid and consistent deployment, their growing adoption has also raised significant security concerns. Each container is an isolated instance of an operating system that comes pre-packaged with the users desired applications. With multiple containers running on a host machine, an adversary can potentially break out of the container into the host machine. This project investigates the effectiveness of user namespace isolation as a security mechanism to mitigate container escape vulnerabilities that target the container’s runtime.

The research questions are: Question 1, does user namespace isolation mitigate container runtime vulnerabilities that target …

Marianismo:Challenging Traditional Mexican-American Roles For Women, Clarissa Aileen Montalvo

Electronic Theses, Projects, and Dissertations

While plentiful research has examined Machismo as a gender role norm for Mexican men, little has examined the role of women’s traditional Marianismo roles. Research identifies 5 “pillars” of Marianismo: family, virtuosity, subordination, self-silencing, and spirituality. I was interested in whether adhering to some traditional pillars of Marianismo (e.g., family) allow women to break away from other, more oppressive pillars (e.g., subordination, self-silencing). I tested whether traditional Marianismo beliefs impact women’s general mental health, and whether differences in traditional beliefs influence the degree to which women can be challenged to push back against more negative pillars by focusing on the …

Artificial Intelligence And Cracks In The Foundation Of Intellectual Property, Robin C. Feldman

Faculty Scholarship

Our implicit image of progress and the standards we use to calibrate human contribution to progress are quietly at risk from the onslaught of artificial intelligence (AI). AI has the potential to significantly shrink the pool of creative work that is protectable by intellectual property (IP) law and the range of information that is protectable, as well as shrinking the value proposition of IP regimes themselves.

As society faces this changing landscape, we must tread carefully to distinguish fears about AI from the task of defining the boundaries of intellectual property, whose theoretic concepts aren’t designed to bear such weighty …

(R2104) On The Qualitative Results Of Riemann-Liouville Fractional Order Nonlinear Neutral Singular Systems With Mixed Delays, Abdullah Yiğit, Cemil Tunç

Applications and Applied Mathematics: An International Journal (AAM)

In this manuscript, we discuss new conditions for asymptotic stability of nonlinear Riemann- Liouville fractional mixed-delay neutral singular systems. By constructing a set of improved Lyapunov-Krasovski˘ı functionals (LKFs), we establish some new delay-dependent conditions in terms of matrix inequality, which guarantees that the systems are asymptotically stable. In the particular case, we give four numerical examples with their solutions and graphs via MATLAB software demonstrating the practical applicability of these proven conditions. With this study, some conditions existing in the literature are developed and generalized.

(R2113) A Numerical Method For Solving Linear First-Order Volterra Integro-Differential Equations With Integral Boundary Condition, Zelal Temel, Musa Cakir

Applications and Applied Mathematics: An International Journal (AAM)

We investigate an efficient numerical method for the linear first-order Volterra integro-differential equations with integral boundary condition. To solve this problem, boundaries are determined for its derivative and the solution. The numerical solutions of the problem are modeled over a uniform mesh using the composite right-side rectangle concept for the integral component and the implicit difference rules for the differential component. Next, the stability and convergence of the numerical approach are discussed. The numerical experiments are presented confirming the accuracy of the proposed scheme.

Alfred Russel Wallace Notes 33. The Story In Evolution., Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823-1913) is best known for his independent formulation of the principle of natural selection. In this work I first review my understanding of Wallace’s intellectual development on this subject, including the notion that he had no model for the evolution of higher consciousness as of his first treatment of natural selection in 1858. This leads to some conclusions about his approach to the subject, and links to parallel ideas inherent in the philosophy of Baruch de Spinoza (1632-1677).

Strategic (Non)Disclosure: Activation And Avoidance Of Social Ties Among Women Seeking Abortion, Kathleen Broussard

Faculty Publications

The increased politicization of sexual and reproductive health has created barriers to medically necessary care. In absence of formal health care, social ties become critical sources of information and resources, yet the disclosure of stigmatized health needs carries significant risk. How do people navigate the risks and benefits of disclosure when seeking care for stigmatized needs? Drawing on original survey data (N = 153) and in-depth interviews (N = 55) with women who attempted a self-managed abortion, I first describe the distinct roles of weak and strong ties in women’s health-seeking experiences. I then demonstrate how both partial disclosure and …

Glacial Erosion Rates From The Last Glacial Maximum To Present In Southern Patagonia (50°S), Anastasia Fedotova

Earth Sciences Theses and Dissertations

Over the past few decades, the notion of exogenic processes (e.g. weathering, erosion) contributing to mountain building rather than destruction has become increasingly supported through both direct observations and modeling. As a result, the details of the link between erosion, and therefore climate, and the tectonic evolution of mountain ranges, have progressively become established. One of the key observations emerging from the climate-tectonic debate has been the role of glaciers as powerful landscape sculptors, sensitive to climate signals. The reconstruction of glacial environments evolution and the recovery of patterns of glacial erosion over time have proven key to understanding feedbacks …

Environmental Impact Assessments (Eia): Analysis Of Transboundary Environmental Impact Assessments For The Development Of A Uniform Teia Model, Nicolas Chapa

Open Access Theses & Dissertations

This dissertation investigates the evolution, processes, and importance of Environmental Impact Assessments (EIAs), focusing on transboundary EIAs and the need for a uniform framework. Originating from the National Environmental Policy Act (NEPA) of 1969 in the U.S., EIAs have become globally adopted instruments for assessing and mitigating environmental impacts of development projects. This work reiterates historical milestones, strengths, and current limitations of EIAs. Research also included a review of environmental regulations from Mexico, such as the General Law on Ecological Equilibrium and Environmental Protection (LGEEPA). Through several case studies requiring the use of transboundary EIAs, where shared resources and concerns …

Theses/Capstones/Creative Projects

This study investigated opioid-related knowledge and experiences among 83 Nebraska college students, with an emphasis on awareness, perceived risks, and educational needs regarding opioids and the overdose-reversing drug, naloxone. For participants who have used opioids outside of a doctor’s orders, questions were asked regarding motivations, comorbidities, coping mechanisms, and treatment experiences. Data were collected via an anonymous survey featuring closed- and open-ended questions. Results showed that 41% of participants reported feeling moderately knowledgeable about opioid risks, while 34% felt only slightly knowledgeable. Although 80.7% of participants were aware of naloxone, most were uncertain either about (22.9%) or did not know …

Detecting N-Phenyl-2-Naphthylamine, L-Arabinose, D-Mannose, L-Phenylalanine, L-Methionine, And D-Trehalose Via Photocurrent Measurement, Feng Li, Ruoxi Yang, Jian Xu, Guohai Xu, Ye Wu

Faculty Publications

The concentration of small molecules reflects the normality of physiological processes in the human body, making the development of simple and efficient detection equipment essential. In this work, inspired by a facile strategy in point-of-care detection, two devices were fabricated to detect small molecules via photocurrent measurement. A linear response of the photocurrent against the concentration of the small molecules was found. In the first device, metal ions were introduced into gel substrates made by xanthan gum to enhance photocurrent response. N-phenyl-2-naphthylamine was measured when iron or manganese ions were used. L-Phenylalanine was measured when the gel was modified by …

Cmos-Based Rotational Spectroscopy: Massive Spectral Fingerprint Generation And Molecular Detection With Deep Learning, Yasamin Fozouni

Computer Science and Engineering Theses and Dissertations

Rotational Spectroscopy is a powerful spectral fingerprinting approach that can be used for identifying different gas molecules in a sample. Gas molecules are free to rotate, with inertia, in fixed states of quantized energy. In Rotational Spectroscopy, radiative beams are shown onto a sample to cause an energy-based transition between quantized rotational states. By sweeping the frequency of the radiative beams and monitoring the absorption with a sensor, one can profile the different rotational states, monitoring for energy based transitions. These transitions are dependent on unique properties of the molecules, thus presenting a unique molecular identification fingerprint (in the form …

Power At Sea Oscillating Water Column, Nate Hempstead, Max Wong, Ned Eyre Eyre, Luke Wierl

Mechanical Engineering

Current Autonomous Underwater Vehicles (AUVs) are predominantly powered by batteries or other energy sources that require frequent maintenance and human intervention. To increase the deployment times and efficiencies of AUVs, there is a need to develop improved wave energy conversion systems that harness renewable energy from waves and tides for power generation and storage. This approach aims to reduce or eliminate the need for manual maintenance or battery replacements, while also minimizing the environmental impact on marine wildlife and the surrounding ecosystem.

One Is Not Enough: Session, The Social Status Provision, And Consistent And Definitive Constructions, Miles C. Skedsvold

Mercer Law Review

Originalism really is “a theory working itself pure.” But most of the blood, sweat, and tears in the enterprise are spilled over the federal constitution. At least partially as a result of those efforts, though, more and more important legal questions are examined under state law—and in particular, state constitutions. And so it is more important than ever to work through the hard methodological questions that will help produce answers. Presiding Justice Nels S.D. Peterson’s landmark article “Principles of Georgia Constitutional Interpretation” breaks key ground in this area—and this Article aims to take the shovel and keep digging. ...

Premises Liability And Third-Party Attacks: A Path Forward, Pamela A. Wilkins

Mercer Law Review

Recently, in Georgia CVS Pharmacy, LLC v. Carmichael, the Supreme Court of Georgia recognized a totality of circumstances approach for determining whether a landowner owes a duty to protect patrons from third-party attacks. So right now, in Georgia, the poor lighting, high-crime surroundings, and absence of functioning panic boxes are relevant considerations for the duty calculus.

Many members of the Georgia General Assembly find this outcome intolerable. Only months after the court’s ruling in Georgia CVS Pharmacy, several state senators, focusing on the supposed “unfriendliness to business” of the current totality of circumstances rule, introduced a bill that …

Insurance, Maren R. Cave, Jessica Phillips, Rebecca Strickland

Mercer Law Review

During this Survey period, the most important development was the Georgia General Assembly’s enactment of critical changes to the statute related to pre-suit demands in automobile cases. These changes to O.C.G.A. § 9-11-67.1 may very well mark the ultimate end of litigation in Georgia’s appellate courts related to what constitutes a binding settlement in automobile cases involving time limited demands. The Survey period also saw a number of decisions in the “first party” area where Georgia courts strictly upheld the insurance contract provisions related to suit limitations and reformation of those policies, and another decision related to “recoupment” of defense …

Torts, Scott Key

Mercer Law Review

2023—2024 brought significant changes to the law of torts in the Supreme Court of Georgia, the Court of Appeals of Georgia, and the Georgia General Assembly. The most significant changes involve precedent loosening the reasonable foreseeability standard in negligence cases and the end of direct actions against insurers in motor carrier cases. This was a busy year in tort law, with sweeping changes from the courts and the legislature.
