Accident Simulation Study For Nuclear Power Plants Impacting Louisiana, Michael D. Mcmahon

LSU Master's Theses

INTRODUCTION: Louisiana has aligned its radiological emergency program with the 2017 Environmental Protection Agency Protective Action Guides Manual, but has added a child thyroid dose evacuation threshold in lieu of distributing Potassium Iodide to the public. The nuclear power plants will continue to align with the 1992 manual for the foreseeable future, so that under some accident scenarios the state recommendations will differ from those of the utility.

OBJECTIVE: The objective of this study is to predict what accident and weather conditions will lead to a differing set of recommendations.

METHODS: More than 1000 simulations were performed of low-filtration nuclear …

Aspartyl Protease Inhibitors As Anti-Filarial Drugs, Liana Beld, Hyeim Jung, Christina A Bulman, Bruce A Rosa, Peter U Fischer, James W Janetka, Sara Lustigman, Judy A Sakanari, Makedonka Mitreva

2020-Current year OA Pubs

The current treatments for lymphatic filariasis and onchocerciasis do not effectively kill the adult parasitic nematodes, allowing these chronic and debilitating diseases to persist in millions of people. Thus, the discovery of new drugs with macrofilaricidal potential to treat these filarial diseases is critical. To facilitate this need, we first investigated the effects of three aspartyl protease inhibitors (APIs) that are FDA-approved as HIV antiretroviral drugs on the adult filarial nematode,

Fondaparinux As An Alternative Anticoagulant Treatment In Patients With Left Ventricular Assist Devices And Recurrent Gastrointestinal Bleeding: Case Series, Daniela Piani, Andrea Lechiancole, Massimo Maiani, Igor Vendramin, Sandro Sponga, Elisabetta Auci, Ugolino Livi

The VAD Journal

Gastrointestinal bleeding (GIB) can occur in patients after left ventricular assist device (LVAD) implantation. In cases of recurrent GIB, the management of anticoagulation treatment represents a challenging situation in which the risk of bleeding recurrence and the need for long-term anticoagulation must be balanced. This case series describes the successful management of anticoagulation in three patients with recurrent GIB using fondaparinux.

To our knowledge, these are the first reported cases of recurrent GIB in which a single dose of subcutaneous fondaparinux was used instead of oral anticoagulation. None of the patients presented with signs of pump thrombosis or arterial embolism. …

Anxiety Symptoms Among Extension Professionals' During The Covid-19 Pandemic With The Gad-2, Glenn D. Israel, Colleen E. Gariton, Harsha E. James

Journal of Rural Social Sciences

According to the National Institute of Mental Health, anxiety disorders are a common mental health disorder but often remain undetected and undertreated. During the COVID-19 pandemic, Extension professionals have worked hard to address emerging issues that communities face, possibly impacting the amount of anxiety they experience. This study determined the prevalence of anxiety symptoms among Extension professionals in the United States. Participants from 24 states completed a survey containing the Generalized Anxiety Disorder 2-item (GAD-2) screener. Almost one-quarter of Extension professionals had a GAD-2 score greater than three, an indicator of anxiety with a possibility of generalized anxiety disorder, which …

Implications Of Covid-19 Mitigation Policies On Recreational Trail Users: Exploring Antecedents To Physical Distancing On Trails Across The Rural-Urban Continuum, Christopher J. Wynveen, Ingrid Schneider, Deonne Vanderwoude, Taylor Stein, Heather Gibson, Kim Shinew, William Hendricks, Megha Budruk

Journal of Rural Social Sciences

The COVID-19 pandemic and subsequent travel restrictions led to a worldwide increase in greenspace use. The U.S. Centers for Disease Control and Prevention encouraged policies including physical distancing and COVID-related signage. However, the extent to which these policies influenced behavior is unknown. To fill this gap, we report on a 2020 observational study at 14 trails across six U.S. states framed within a social-ecological model. Behavioral observations of 8,093 groups assessed compliance rates with infection-mitigation behaviors. Additionally, we noted the presence of COVID-related signs, the days between the observation and stay-at-home order start date, the setting (i.e., urban, suburban, and …

Preventive Behaviors Along The Rural-Urban Continuum In Utah During The Covid-19 Pandemic, Jessica D. Ulrich-Schad, Jennifer E. Givens, Mitchell Beacham

Journal of Rural Social Sciences

Rural individuals and places face major vulnerabilities in relation to the COVID-19 pandemic, yet how and why rural residents adopted preventive behaviors as a result is not well understood. Using cross-sectional data from an online panel survey of Utahans along the rural-urban continuum collected in June of 2020, we find that, overall, rural Utahans were less likely than their more urban counterparts to adopt preventive behaviors. Those who perceived less risk, knew someone sick with COVID-19, thought former President Trump was doing a good job handling the pandemic, had false optimism about the pandemic, had less formal education, and belonged …

Rural-Urban And Within-Rural Differences In Covid-19 Mortality Rates, Yue Sun, Kent Jason G. Cheng, Shannon M. Monnat

Journal of Rural Social Sciences

Since late-2020, COVID-19 mortality rates have been higher in rural than in urban America, but there has also been substantial within-rural heterogeneity. Using CDC data, we compare COVID-19 mortality rates across the rural-urban continuum as well as within rural counties across different types of labor markets and by metropolitan adjacency. As of October 1, 2021, the cumulative COVID-19 mortality rate was 247.0 per 100,000 population in rural counties compared to 200.7 in urban counties. Higher COVID-19 mortality rates in rural counties are explained by lower average educational attainment and lower median household income. Within rural counties, mortality rates have been …

Factors Explaining Variations In Covid-19 Deaths In Rural America, Don E. Albrecht

Journal of Rural Social Sciences

Early in the COVID-19 pandemic, case and death rates from the disease in rural counties were significantly lower than in urban counties. This pattern changed during the summer and fall of 2020, and by December, death rates in rural counties were higher than in urban counties. This article uses data from the U.S. Census Bureau and voting and COVID-19 data from The New York Times to explore factors related to the increase in COVID-19 deaths in rural counties in the United States. Further analysis is conducted to understand variations in death rates across different types of rural counties. Multivariate regression …

Comprehensive Local Injury Surveillance For Pediatric Fatal And Nonfatal Firearm Injury Prevention Planning, Bindi Naik-Mathuria, Ned Levine, Cary Cain, Abiodun O. Oluyomi, Mike Henson-Garcia, Lisa Pompeii

Journal of Applied Research on Children: Informing Policy for Children at Risk

Injury by firearm is now the leading cause of death in children in the U.S.. Effective injury prevention requires first defining the problem and identifying risk and protective factors before implementing prevention strategies. There is no comprehensive source available to define firearm injuries, especially at the local level. We propose a local firearm injury surveillance model based on the socio-ecological injury prevention framework that combines injury data from health care, law enforcement, county services, and census data that can help to guide targeted firearm injury prevention interventions.

A 27-year-old male patient was diagnosed as severe obstructive sleep apnea (OSA), having problems of skeletal Class II jaw related with mandibular retrognathism, orthodivergent facial pattern, dental Class II malocclusion, and occlusal plane canting. By intervention of miniscrew assisted rapid palatal expansion (MARPE) and maxillomandibular advancement (MMA), the clinical result presented significant improvement in functional and esthetic aspects after 18 months of treatment.

Strategies Of Non-Extraction Treatment For Class Lll Malocclusion, Tao-Wei Chang, Hoi-Shing Luk, Wen-Ken Tai, Chih-Chen Chou, Chia-Tze Kao

Taiwanese Journal of Orthodontics

The decision of whether to have an extraction or non-extraction treatment plan is a controversial issue for an orthodontist. Many orthodontic techniques can help to resolve the crowding dentition by using the non-extraction treatment plan. This case report describes the correction of Class III molar malocclusion with the application of two mini-screws. The line of action of the force from the temporary anchorage devices pass through the center of resistance in the mandible, therefore the movement of the lower arch can be controlled without lingual tipping or intrusion of the mandibular incisors. At the end of the treatment, Class I …

The mucosal patches were placed …

Important Orthodontic Considerations In Preparation Of Orthognathic Surgical Cases, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

Nowadays some adult patients seeking for orthodontic treatment may present severe malocclusion associated with pronounced skeletal discrepancies. Accordingly, thorough consideration and planning would be beneficial for the patient by the combined efforts of orthodontic and orthognathic approaches. This review reiterated the genetic impact on the growth velocity of the jaw with age in Class III malocclusion, and outlined the treatment protocol for the steps including the initial evaluation, the diagnosis, and the alignment of the teeth and dental arches before and after surgical correction. Specifically, emphasis is addressed on how to obtain records of jaw relationship in centric relation (CR) …

Functional Requirements For A Samd14-Capping Protein Complex In Stress Erythropoiesis, Suhita Ray, Linda Chee, Yichao Zhou, Meg A. Schaefer, Michael J. Naldrett, Sophie Alvarez, Nicholas T. Woods, Kyle J. Hewitt

Nebraska Center for Biotechnology: Faculty and Staff Publications

Acute anemia induces rapid expansion of erythroid precursors and accelerated differentiation to replenish erythrocytes. Paracrine signals—involving cooperation between stem cell factor (SCF)/Kit signaling and other signaling inputs—are required for the increased erythroid precursor activity in anemia. Our prior work revealed that the sterile alpha motif (SAM) domain 14 (Samd14) gene increases the regenerative capacity of the erythroid system in a mouse genetic model and promotes stress-dependent Kit signaling. However, the mechanism underlying Samd14’s role in stress erythropoiesis is unknown. We identified a protein-protein interaction between Samd14 and the α- and β-heterodimers of the F-actin capping protein (CP) complex. Knockdown of …

Cardiac Rehabilitation Adherence Rates In Elderly Patients Using A Mobile Application, Amanda Wilson

Yale School of Medicine Physician Associate Program Theses

Adherence to cardiac rehabilitation reduces cardiovascular disease mortality. Despite this, adherence rates remain suboptimal especially among older patients. Mobile applications are increasingly utilized to deliver virtual healthcare with similar health outcomes. However, no studies have determined whether cardiac rehabilitation delivered via mobile applications can increase adherence rates in elderly patients who may be limited by logistical barriers, such as difficulties with transportation. The aim of this study is to examine whether cardiac rehabilitation conducted via mobile application can increase adherence rates to cardiac rehabilitation in patients over 65 years old compared with traditional cardiac rehabilitation. We will conduct a randomized, …

Actuator Cyberattack Handling Using Lyapunov-Based Economic Model Predictive Control, Keshav Kasturi Rangan, Henrique Oyama, Helen Durand

Chemical Engineering and Materials Science Faculty Research Publications

Cybersecurity has gained increasing interest as a consequence of the potential impacts of cyberattacks on profits and safety. While attacks can affect various components of a plant, prior work from our group has focused on the impact of cyberattacks on control components such as process sensors and actuators and the development of detection strategies for cybersecurity derived from control theory. In this work, we provide greater focus on actuator attacks; specifically, we extend a detection and control strategy previously applied for sensor attacks and based on an optimization-based control technique called Lyapunov-based economic model predictive control (LEMPC) to detect attacks …

Test Methods For Image-Based Information In Next-Generation Manufacturing, Henrique Oyama, Dominic Messina, Renee O'Neill, Samantha Cherney, Minhazur Rahman, Keshav Kasturi Rangan, Govanni Gjonaj, Helen Durand

Chemical Engineering and Materials Science Faculty Research Publications

Typical control designs in the process systems engineering literature have assumed that the primary sensing methodologies are traditional instruments such as thermocouples. Dig- italization is changing the landscape for manufacturing, and data-based sensing modalities (e.g., image-based sensing) are becoming of greater interest for plant control. These considerations require novel test/evaluation solutions. For example, process systems engineering researchers may wish to test image-based sensors in simulation. In this work, we provide preliminary thoughts on how image-based technologies might be evaluated via simulation for process systems.

Quantum Computing And Resilient Design Perspectives For Cybersecurity Of Feedback Systems, Keshav Kasturi Rangan, Jihan Abou Halloun, Henrique Oyama, Samantha Cherney, Ilham Azali Assoumani, Nazir Jairazbhoy, Helen Durand, Simon Ka Ng

Chemical Engineering and Materials Science Faculty Research Publications

Cybersecurity of control systems is an important issue in next-generation manufac- turing that can impact both operational objectives (safety and performance) as well as process designs (via hazard analysis). Cyberattacks differ from faults in that they can be coordinated efforts to exploit system vulnerabilities to create otherwise unlikely hazard scenarios. Because coordination and targeted process manipulation can be characteristics of attacks, some of the tactics previously analyzed in our group from a control system cybersecurity perspective have incorporated randomness to attempt to thwart attacks. The underlying assumption for the generation of this randomness has been that it can be achieved …

Challenges And Opportunities For Next-Generation Manufacturing In Space, Kip Nieman, A. F. Leonard, Katie Tyrell, Dominic Messina, Rebecca Lopez, Helen Durand

Chemical Engineering and Materials Science Faculty Research Publications

With commercial space travel now a reality, the idea that people might spend time on other planets in the future seems to have greater potential. To make this possible, however, there needs to be flexible means for manufacturing in space to enable tooling or resources to be created when needed to handle unexpected situations. Next-generation manufacturing paradigms offer significant potential for the kind of flexibility that might be needed; however, they can result in increases in computation time compared to traditional control methods that could make many of the computing resources already available on earth attractive for use. Furthermore, resilience …
