The molecular weight of polyethylene glycol was varied (100, 200, and 4000) to study its effect on the stabilization of silver nanoparticles (AgNPs) and the catalytic activity of the resulting samples. The results showed that the catalyst with …

A Phase 1 Randomized Trial Of Homologous And Heterologous Filovirus Vaccines With A Late Booster Dose, Christina A Rostad, Carol Kao, Et Al.

2020-Current year OA Pubs

Filoviruses, including Ebola, Marburg, Sudan, and Taï Forest viruses, are zoonotic pathogens that can cause severe viral hemorrhagic fever and death. Developing vaccines that provide durable, broad immunity against multiple filoviruses is a high global health priority. In this Phase 1 trial, we enrolled 60 healthy U.S. adults and evaluated the safety, reactogenicity and immunogenicity of homologous and heterologous MVA-BN®-Filo and Ad26.ZEBOV prime-boost schedules followed in select arms by MVA-BN®-Filo boost at 1 year (NCT02891980). We found that all vaccine regimens had acceptable safety and reactogenicity. The heterologous prime-boost strategy elicited superior Ebola binding and neutralizing antibody, antibody-dependent cellular cytotoxicity …

Clocking In And Speaking Out: Navigating Workday Rhythms For Voice Behaviors, Katelyn M. Reeves

LSU Master's Theses

Employee voice behaviors help organizations identify problems, increase productivity, and enhance satisfaction. Most literature focuses on daily-level variations while neglecting potential within-day variations that may have a stronger impact on voice engagement. To investigate within-day variations, this thesis applies chronotype synchrony to explain resource depletion throughout the day, which will determine voice engagement. An experience sampling study with the day reconstruction method of 250 employees revealed that having a morning chronotype leads to a more promotive and prohibitive voice in the morning, with a decline throughout the day due to resource depletion increasing throughout the day. Further, individuals with evening …

Physics-Informed Heterogeneous Spatiotemporal Graph Neural Network For Reservoir Simulation, Ahmed A.M.A. Abdullah

LSU Master's Theses

Reservoir simulation is the state-of-the-art method for predicting the flow of petroleum reservoir fluids in porous media. It provides an accurate and unbiased prediction of the performance of petroleum reservoirs under different operating conditions. Despite its advantages, reservoir simulation is computationally expensive; with typical full-field simulation models running for several hours. This limitation is worsened when simulating reservoirs with several equations for each cell, such as multiphysics or compositional reservoir simulation. The goal of this research is to provide a fast and accurate spatiotemporal machine-learning model that incorporates discretized governing mass balance equations for training. To achieve this, we propose …

Reconstructing Superoscillations Buried Deeply In Noise, Derek D. White, Shunxing Zhang, Barbara Šoda, Achim Kempf, Daniele C. Struppa, Andrew N. Jordan, John C. Howell

Mathematics, Physics, and Computer Science Faculty Articles and Research

We utilize a method using frequency combs to construct waves that feature superoscillations—local regions of the wave that exhibit a change in phase that the bandlimits of the wave should not otherwise allow. This method has been shown to create superoscillating regions that mimic any analytic function—even ones well outside the bandlimits—to an arbitrary degree of accuracy. We experimentally demonstrate that these waves are extremely robust against noise, allowing for accurate reconstruction of a superoscillating target function thoroughly buried in noise. We additionally show that such a construction can be easily used to range-resolve a signal well below the commonly …

Introduction: Cigarette use and smoking intensity increase risk of suicidal ideation. Less is known about e-cigarette use. Here we examine direct influences of cigarette versus e-cigarette use on suicidal ideation among 16- to 23-year-olds in Texas.

Aims and methods: Since 2019, the Texas Adolescent Tobacco and Marketing Surveillance Study collected data on suicidal ideation every 6 months covering the previous 2 weeks. Youths answering that they had "thoughts that you would be better off dead, or of hurting yourself" on more than 2 of 14 days were categorized as having suicidal ideation. Generalized linear mixed-effects logistic regressions examined the influence …

Type Of Orientation And Differences In Role Transition, Unit Support, Job Satisfaction And Retention Among New Graduate Nurses, Kimber Lee Zolnier

Walden Dissertations and Doctoral Studies

Many new graduate nurses leave the nursing profession during the first year of practice due to inadequate orientation and lack of support. Successful transition to practice is often hindered as new graduate nurses may be assigned to more than one clinical unit and receive feedback from multiple preceptors, leading to frustration and lack of confidence when feedback is inconsistent. The purpose of this quantitative cross-sectional study, guided by the Dreyfus model of skill acquisition and Benner’s novice to expert theory, was to determine if there is a difference among new graduate nurses’ experiences with role transition, job satisfaction, retention, and …

Racism, Depression, And The Superwoman Schema: A Narrative Inquiry With Fourth-Grade Black Girls, Athena Hall

Walden Dissertations and Doctoral Studies

In the United States, racism has been labeled a public health emergency. Amid rising rates of racism reported in schools, many Black girls aged 5 to 12 have severe and persistent symptoms of depression. Although Woods-Giscombé’s Superwoman Schema (SWS) is an acknowledged coping mechanism that Black women and adolescent girls can use to fight and transcend interconnected systems of racial and gender oppression, it has rarely been studied among pre-adolescent girls. The purpose of this qualitative narrative inquiry was to explore the lived experience of the SWS among fourth-grade Black girls in Detroit, Michigan. The theoretical framework was the SWS. …

Introduction: Failed Futures? (Post)-Colonial Planning And Future-Making In Tanzania, Ulrike Lindner

Zamani: A Journal of African Historical Studies

Future-making and planning as social practices are strongly related to the
surrounding society’s political structures and power relations. In this
special issue of ZAMANI, we conceptualize future-making as physical
changes and social practices that shape future conditions by making future
an issue in the present. We analyse how different approaches to the future,
and also surprises and unintended side-effects, have informed the politics
and practices of planning in Tanzania and its various regions.1 When we ask:
“Failed Futures?” we address future in the plural, a term that has diffused
into historical scholarship rather recently and originates from
futurology/future studies, known …

‘Sold Down The River’: Histories Of Production, Trade, And Transport Along The Waterways Of The Kilombero Valley, Tanzania, Jonathan M. Jackson

Zamani: A Journal of African Historical Studies

This article considers the centrality of waterways in the Kilombero Valley of Tanzania to the region’s histories of development from above, particularly in terms of infrastructure, crop production, trade, and transport. Early colonial investigations hoped Kilombero’s riverine system might prove a navigable link from the coast to the Southern Highlands. The British colonial era instead focused more on utilising riverine networks for internal goods transport. Throughout these colonial visions – simultaneously ambitious and naïve – the prevalent dug- out canoe was considered unsafe, inefficient, and replaceable by modernised methods. But the canoe – a symbol of indigenous knowledge and practice …

Imagining Hydropower: Transnational Narratives And Realities Of The Stiegler’S Gorge Project In Tanzania, 1960s–1980s, Emma Athanasio Minja

Zamani: A Journal of African Historical Studies

Hydropower development in the Global South has attracted several donor programmes for decades. How have such interventions shaped energy imaginations in Tanzania? Adopting a historical perspective and drawing on transnationalism and travelling frameworks, this article examines hydropower aid interventions and the dynamic shifts of specific actors and discourses in bilateral relations. The primary focus is on Norway, a leading actor in planning the Stiegler’s Gorge hydropower project in Tanzania’s Rufiji Basin in the 1970s to mid-1980s. It seeks to understand how, despite substantial aid support, the project failed to kick off in the face of the country’s post-independence drive for …

Nurturing Traditional Midwifery And Medicine: The Entangled Path Of Health Integration In Post-Independence Kilombero, Tanzania, Veronica Kimani

Zamani: A Journal of African Historical Studies

This paper focuses on the Tanzanian government’s ambitious endeavour to enhance health, particularly midwifery services following independence. The initial strategy by the government involved promoting Western medicine by establishing healthcare facilities and training medical personnel. However, the strain of a burgeoning population and limited resources soon became evident, prompting the government to recognise the need for the incorporation of traditional medicine, previously overlooked. This integration posed its own set of obstacles, as the focus on herbal remedies overshadowed crucial aspects of conventional midwifery, such as rituals. While research has shown the resolve of the government towards medical integration between different …

Health Infrastructure Planning In Tanzania, 1961–1980s: The Problems Of Future-Making, Frank Edward, Ulrike Lindner

Zamani: A Journal of African Historical Studies

Between 1961 and 1978, Tanzania invested significantly in the health service provision – from training requisite manpower, provision of health education to building the necessary infrastructure in order to improve health conditions of the population. As existing research indicates, the investment paid off considerably in qualitative terms, for instance, with a gradual increase in life expectancy and a decline in infant mortality. This paper examines the vision of the state of health in Tanzania by using the prism of infrastructure. Its focus is on direct and indirect physical infrastructures, particularly medical buildings and facilities. Through the analysis of archival and …

Design, Control, And Evaluation Of A Photovoltaic Snow Removal Strategy Based On A Bidirectional Dc-Dc Converter For Photovoltaic–Electric Vehicle Application, Salma Elakkad, Mohamed Hesham, Hany Ayad Bastawrous, Peter Makeen

Electrical Engineering

A novel self-heating technique is proposed to clear snow from photovoltaic panels as a solution to the issue of winter snow accumulation in photovoltaic (PV) power plants. This approach aims to address the shortcomings of existing methods. It reduces PV cell wear, resource loss, and safety risks, without the need for additional devices. A self-heating current is applied to the solar panel to melt the snow covering its surface, which is then allowed to slide off the panel due to gravity. The proposed system consists of a bidirectional DC-DC converter, which removes the snow cover by heating the solar PV …

Transparency And Authority Concerns With Using Ai To Make Ethical Recommendations In Clinical Settings, Jeffrey Byrnes, Michael Robinson

Philosophy Faculty Articles and Research

In response to recent proposals to utilize artificial intelligence (AI) to automate ethics consultations in healthcare, we raise two main problems for the prospect of having healthcare professionals rely on AI-driven programs to provide ethical guidance in clinical matters. The first cause for concern is that, because these programs would effectively function like black boxes, this approach seems to preclude the kind of transparency that would allow clinical staff to explain and justify treatment decisions to patients, fellow caregivers, and those tasked with providing oversight. The other main problem is that the kind of authority that would need to be …
