Synthesis Of Mixed Metal High Entropy Oxyhalide For Photocatalytic Degradation Of Tetracycline, Chakgrid Noomak

Chulalongkorn University Theses and Dissertations (Chula ETD)

High entropy materials (HEMs) are new types of materials that contain five or more elements. HEMs have been applied in various applications. It has been proven that HEMs with multielement can provide good structural stability. However, the application of HEMs in the field of photocatalytic has rarely been reported. Therefore, it is interesting to construct HEMs to be used as photocatalysts. In this work, we designed and fabricated a mixed metal high entropy halide (SrxBa1-xBiO2Br), a novel photocatalyst that contains five elements in the structure, by incorporating metals (Sr and Ba) into bismuth oxybromide material (BiOBr) to enhance their stability …

Institutions of learning that were once deemed safe and sacred have turned into metaphorical and literal battlegrounds (Jonson, 2017). As a result of the increased risk of mass school shootings many states have implemented laws to assist in implementing more rigid safety measures within …

Training A Public Accommodations Lens On Vaccine Passports, Paul Diller

Lewis & Clark Law Review

The Covid pandemic and the rise of smartphone technology enabled the use of “vaccine passports”—that is, a requirement to show proof of vaccination against Covid—on a scale unmatched before in human history. In the United States, many public accommodations such as restaurants, coffee shops, stadiums, and movie theaters required patrons to show proof of vaccination in order to enter or consume food and drink on the premises. In approximately two dozen local jurisdictions as well as the District of Columbia and Puerto Rico, government mandated that public accommodations do this, with varied carveouts for religious objections and medical or age-based …

Pandemic Communication: International Communication, Anthony Spencer

Other Scholarly Publications

The COVID-19 pandemic has transformed our world as we previously knew it. One of those major changes is how we communicate with one another across national borders. The pandemic forced us to find ways to improve the way we utilize social media outlets to communicate with others around the world. Research into global communication has long been too focused on the West, and particularly the United States. This shift in our communication usage also provides a moment of pause to reflect on ways to make the field of international communication more inclusive and focus on key issues which influence transnational …

The Covid-19 Pandemic And Its Influence On The Human Immune System, Nicole L. Riha

Undergraduate Honors Theses

COVID-19 rapidly infected the world, and scientists continue to research how the disease spread and killed as many as it did by analyzing how it affects the human immune system and referring to past pandemics. Since the pandemic is ongoing, scientists do not fully understand how the virus works and if lockdowns were effective. Nevertheless, a discussion on what is known about COVID-19's influence on the human immune system is needed. With an understanding of the COVID-19 pandemic, scientists can make more effective treatments for COVID-19 and learn how to manage future pandemics.

Interagency Dynamics In Matters Of Health And Immigration, Medha D. Makhlouf

Faculty Scholarly Works

When Congress delegates authority to an executive agency, it tells us something important about the expertise that Congress wishes to harness in policymaking on an issue. In the legal literature on interagency dynamics and cooperation, issues at the nexus of health and immigration are largely understudied. This Article extends this literature by examining how delegations of authority on issues at the intersection of health and immigration influence policymaking. In an analysis of how administrative law models apply to three topics in the shared regulatory space of the Department of Health and Human Services (“HHS”) and the Department of Homeland Security …

Network Structure And Network Effectiveness In Thailand's Provincial Covid-19 Response Networks, Ruechagorn Trairatananusorn

Electronic Theses and Dissertations, 2020-2023

Health and well-being are key focuses for international organizations and governments around the world as one of the United Nations' (UN) Sustainable Developmental Goals (SDGs). The emergence of COVID-19 pandemic since late 2019 has led to not only substantial life losses, but also negative social and economic impacts that are relatively comparable to the "Spanish Flu" pandemic. The insights from public administration literature suggested that emergency and crisis management require collaborative efforts from various stakeholders across sectors and levels. However, the existing literature that studied the COVID-19 pandemic response under network perspective is still scarce in developing countries, especially in …

Pharmaceuticals From Natural Products: The Utility Of The Phylogeny, Shaimaa Magdy Saad

Selected Full-Text Master Theses 2021-

About 60% of approved drugs during the last 30 years are either directly or indirectly from natural products. Previous studies have shown that the phylogeny has predictive utility in drug discovery. In this study the pharmacological applications of various naturally-derived drugs were mapped on the phylogeny reconstructed from DNA sequences of the source organisms to decipher phylogenetic patterns that may facilitate drug discovery. A multi-step approach was employed starting with a literature search to compile a comprehensive list of pharmaceutical drugs derived from natural sources. A phylogeny was reconstructed from the source organisms and their pharmacological uses mapped on the …

Development Of Narrow-Spectrum Agents And Mray Inhibitors Targeting Multidrug-Resistant Mycobacterium Tuberculosis, Tomayo Ireti Berida

Electronic Theses and Dissertations

Tuberculosis (TB) is a major global health burden. This airborne infectious disease is caused by Mycobacterium tuberculosis (Mtb) and resulted in 1.6 million deaths globally in 2021. The emergence and spread of multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) underscores the urgent need to discover and develop new agents, particularly those with narrow spectrum activity and those acting by novel mechanisms. Although broad-spectrum antibacterials have been successful in treating drug-resistant bacterial infections, including TB, there is a push toward the discovery and development of anti-TB agents with narrow-spectrum activity. This approach aims to limit the spread of resistance across …

Novel Formulation Strategies For Oral And Ocular Drug Delivery, Samir Senapati

Electronic Theses and Dissertations

Nanoformulations such as nanoemulsions (NE), solid lipid nanoparticles (SLN), and nanostructured lipid carriers (NLCs) are colloidal particulate systems in the submicron size range and act as carriers of drug molecules. Their size varies from 10 to 1,000 nm (1). The capacity of these nanoparticles to permeate through many anatomical barriers, the prolonged release of their contents, and their stability on the nanometer scale have widely contributed to their efficacy in drug delivery. Owing to the advantages of nanoformulations, they were further explored in our studies to target different diseases like Dry eye disease (DED), glaucoma, and malaria.

The Democratic Problems With Washington As The Capital, David Fontana

GW Law Faculty Publications & Other Works

Democracy demands a capital city that represents a country and is not removed from it. If the government is to be of the people and for the people, then the capital must be able to relate to the people—and the people to the capital. In the United States, democracy struggles not just because of what happens outside of and comes to Washington, but because of what happens inside Washington. The federal government, in other words, faces democratic problems because of the type of place that Washington is. There are many factors to consider in deciding where a country should be …

The Prepare Mobile Program For Hiv Prevention In Washington D.C., Gabrielle Cochran

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Incidence rates of HIV have decreased in the United States in the past decade, but the southern United States has higher rates of HIV than other regions, and cities in the south, like Washington D.C., have some of the highest rates of HIV incidence in the nation. Risky sexual behavior, needle sharing, and substance use increase the risk of transmitting or acquiring HIV, and these behaviors are more common among unhoused people (CDC, 2021; CPPH, 2022).

Expansion of community resources in cities with high levels of HIV have allowed for many people at high risk for HIV to comply with …

Pfas Clinical Guidance, John Bingham

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Introduction

A broad category of synthetic organic compounds, per- and polyfluorinated alkyl substances (PFAS), forms the impetus for this project. Known compounds in this category are numerous and diverse, with over 4700 identified molecular entities (Panieri, Baralic, Djukic-Cosic, Buha Djordjevic, & Saso, 2022). Their only commonality is the presence of at least one carbon atom that is saturated with fluoride groups. These chemical bonds are exceptionally difficult to break (Tansel, 2022), which incepts both the utility of PFAS compounds and the concerns they raise for human health (Cousins et al., 2020). While PFAS are …

Breastfeeding Promotion In The Workplace, Katie C. Nettesheim

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Breastfeeding is one of the best things a mother can do for her baby. It has many protective qualities including a reduced risk of sudden infant death syndrome (SIDS), asthma, obesity, type 1 diabetes, respiratory infections, ear infections, and stomach bugs for the baby (CDC, 2022). There are also protective qualities for the mother as well, including a reduced risk of high blood pressure, breast and ovarian cancer, and type II diabetes. Breastfeeding exclusively, the infant only receives breastmilk and no other supplementation for 6 months, which maximizes the many benefits that breastfeeding has.

Mental Health Professionals’ Perception Of Medications For Opioid Use Disorder, Patrick M. Mullen

PCOM Psychology Dissertations

Despite the widespread attention and resources allocated to the current opioid crisis, the public health problem persists. A major target in the efforts to combat the opioid crisis is increased accessibility and utilization of medications for opioid use disorder (MOUD). A robust body of evidence supports the effectiveness of medications to treat opioid use disorder (OUD) in reducing overdose deaths and improving overall outcomes. Yet, MOUD continues to be underutilized at alarming rates. Studies have discovered that only one-third of substance use disorder (SUD) treatment sites offer any form of MOUD and approximately 30% of individuals with OUD receive any …

Effect Of Positive Emotion Intervention During Late Pregnancy On Improving Colostrum Secretion: A Randomised Control Trial Protocol, Kechen Xu, Ying Xie, Xiujun Han, Ying Yu, Suqing Liu, Suliu Wu, Qian Yang, Qi Zhang

Community & Environmental Health Faculty Publications

Introduction Though evidence has revealed the beneficial effects of cognitive improvement interventions on breastfeeding, the effect of psychological interventions has rarely been studied. This study aims to test whether promoting a positive emotion intervention, 'Three Good Things' intervention, during the last trimester of pregnancy can enhance early colostrum secretion and breastfeeding behaviours by modulating the hormones associated with lactation (prolactin and insulin-like growth factor I). We will attempt to promote exclusive breastfeeding by using physiological behavioural measures.

Methods and analysis This study is designed as a randomised controlled trial conducted in the Women's Hospital School of Medicine at Zhejiang University …

Community & Environmental Health Faculty Publications

BACKGROUND: Hispanics/Latinos, particularly those that identify as foreign-born, are overrepresented in the agricultural sector in the U.S. Over the course of the COVID-19 pandemic, this subpopulation of farmworkers was recognized as an invaluable group of essential workers unable to implement COVID-19 protections.

METHODS: Previously validated COVID-19 stress scale measures were identified, adapted, and translated to collect COVID-19 stress data from Hispanic/Latino agricultural workers in two heavily agricultural counties in northeastern North Carolina. Participants were recruited using purposive convenience sampling. Data collection took place from June to November of 2021.

RESULTS: The majority of Hispanic/Latino agricultural workers surveyed reported experiencing worries …

Multipatch Stochastic Epidemic Model For The Dynamics Of A Tick-Borne Disease, Milliward Maliyoni, Holly D. Gaff, Keshlan S. Govinder, Faraimunashe Chirove

Biological Sciences Faculty Publications

Spatial heterogeneity and migration of hosts and ticks have an impact on the spread, extinction and persistence of tick-borne diseases. In this paper, we investigate the impact of between-patch migration of white-tailed deer and lone star ticks on the dynamics of a tick-borne disease with regard to disease extinction and persistence using a system of Itô stochastic differential equations model. It is shown that the disease-free equilibrium exists and is unique. The general formula for computing the basic reproduction number for all patches is derived. We show that for patches in isolation, the basic reproduction number is equal to the …

Anti-Tick Vaccine Candidate Subolesin Is Important For Blood Feeding And Innate Immune Gene Expression In Soft Ticks, Krittika Nandy, Comfort Tamakloe, Daniel E. Sonenshine, Hameeda Sultana, Girish Neelakanta

Biological Sciences Faculty Publications

Subolesin is a conserved molecule in both hard and soft ticks and is considered as an effective candidate molecule for the development of anti-tick vaccine. Previous studies have reported the role of subolesin in blood feeding, reproduction, development, and gene expression in hard ticks. However, studies addressing the role of subolesin in soft ticks are limited. In this study, we report that subolesin is not only important in soft tick Ornithodoros turicata americanus blood feeding but also in the regulation of innate immune gene expression in these ticks. We identified and characterized several putative innate immune genes including Toll, Lysozyme …

A Digital Transformation Framework For Biopharma Manufacturing, Frederick K. Johnson

In the current climate of economic uncertainty and social unrest, biopharmaceutical (biopharma) companies face the challenges of changes in consumer behavior, cyber threats, and technological advancement. At the same time, their top priorities are global market growth, strengthening R&D, and undergoing digital transformation (Dx). Given these developments, biopharma organizations must choose a Dx framework as they engage in the digital transformation of their businesses in this high-stakes environment. However, there are significant problems with existing Dx frameworks. Most models are generalized frameworks designed to sell consulting services. Some focus on the enterprise or the manufacturing operations, but not both, and …

Public Health And The Politics Of Haussmannization In Nineteenth-Century Paris, 1830-1870, Mikaela Malsy

CGU Theses & Dissertations

Throughout the Second Empire, Napoléon III and his Prefect of the Seine, Georges Haussmann, engaged in a series of urban reform projects that transformed Paris. These projects, often collectively referred to as Haussmannization, entailed the construction of boulevards, expansion of the sewer system, and clearance of what the state considered insalubrious housing. This term was largely prescribed to worker-class housing and used as a medical justification to target and destroy working-class communities. However, as this paper discusses, the understanding of insalubrity was shaped by hygienists' pathologization of poverty, crime, and working-class militancy in response to the arrival of cholera and …
