Investigating The Role Of The I-Ii Linker In Nav1.5, Emily Wagner
Investigating The Role Of The I-Ii Linker In Nav1.5, Emily Wagner
McKelvey School of Engineering Graduate Student Theses & Dissertations
The cardiac voltage-gated sodium channel, Nav1.5 is essential for initiating the cardiac action potential. Its dysfunction can lead to dangerous arrhythmias, sudden cardiac arrest, and death. Like many channels, its known properties depend heavily on its structure. The functional core of the alpha subunit consists of four homologous repeats (I, II, III, and IV), each formed from a voltage sensing domain and a pore domain. The channel also contains two cytoplasmic termini and three cytoplasmic linkers (I-II, II-III, and III-IV). While most of the channel has been resolved in multiple structures, the I-II and II-III linkers have remained conspicuously absent …

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

This work focuses on the preparation and application of silver nanoparticles/organophilic clay/polyethylene glycol for the catalytic reduction of the contaminants methylene blue (MB) and 4-nitrophenol (4-NP) in a simple and binary system. Algerian clay was subjected to a series of treatments including acid treatment, ion exchange with the surfactant hexadecyltrimethylammonium bromide (HTABr), immobilization of polyethylene glycol polymer, and finally dispersion of AgNPs. 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 …
Clocking In And Speaking Out: Navigating Workday Rhythms For Voice Behaviors, Katelyn M. Reeves
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 …

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 …

Measurement Of Breast Artery Calcification Using An Artificial Intelligence Detection Model And Its Association With Major Adverse Cardiovascular Events, Suzanne Rose, Josette Hartnett, Zachary Estep, Daniyal Ameen, Shweta Karki, Edward Schuster, Rebecca Newman, David Hsi
Department of Medicine Faculty Papers
Breast artery calcification (BAC) obtained from standard mammographic images is currently under evaluation to stratify risk of major adverse cardiovascular events in women. Measuring BAC using artificial intelligence (AI) technology, we aimed to determine the relationship between BAC and coronary artery calcification (CAC) severity with Major Adverse Cardiac Events (MACE). This retrospective study included women who underwent chest computed tomography (CT) within one year of mammography. T-test assessed the associations between MACE and variables of interest (BAC versus MACE, CAC versus MACE). Risk differences were calculated to capture the difference in observed risk and reference groups. Chi-square tests and/or Fisher's …

Scorpiops Reini Sp. N. From Yunnan, China (Scorpiones: Scorpiopidae), Victoria Tang
Euscorpius
Scorpiops reini sp. n. is described from Yingjiang County (Dehong Prefecture, Yunnan Province) based on an adult pair. It can be readily discriminated from all of its congeneric geographic neighbors in Yunnan, namely S. jendeki Kovařík, 1994, S. shidian (Zhu et al., 2005), S. tongtongi Tang, 2022, and S. zhangshuyuani (Ythier, 2019). Within Yunnan, it resembles S. validus (Di et al., 2010) and S. yangi (Zhu et al., 2007) most, but can be identified by its large median ocelli (relative to the width of ocular subislet), pedipalp chelal finger morphology and pectinal tooth count. Beyond Yunnan, it shows the highest …
Introduction: Failed Futures? (Post)-Colonial Planning And Future-Making In Tanzania, Ulrike Lindner
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
‘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
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
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
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
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 …

Predicting Movie Production Years Through Facial Recognition Of Actors With Machine Learning, Asraa Muayed Abdalah, Noor Redha Alkazaz
Baghdad Science Journal
This study used machine learning algorithms to identify actors and extract the age of actors from images taken randomly from movies. The use of images taken from Arab movies includes challenges such as non-uniform lighting, different and multiple poses for the actors and multiple elements with the actor or a group of actors. Additionally, the use of make-up, wigs, beards, and wearing different accessories and costumes made it difficult for the system to identify the personality of the same actor. The Arab Actors Dataset-AAD comprises 574 images sourced from various movies, encompassing both black and white as well as color …

Solving Edges Deletion Problem Of Complete Graphs, Anwar N. Jasim, Alaa A. Najim
Solving Edges Deletion Problem Of Complete Graphs, Anwar N. Jasim, Alaa A. Najim
Baghdad Science Journal
As the network size increases, there is an increased probability that some components will fail. It is therefore necessary for the network to be able to maintain the interconnection even in the presence of faulty components. The likelihood of a failure in the connections between stations is higher than that of a failure in the stations themselves because of the nature of many networks. Numerous graph-theoretic methods can be used to examine the reliability and efficacy of a network, and the network's dependability is determined by its connectivity. For a parallel and distributed system, the maximum connection time between any …

Zamani: A Journal of African Historical Studies
This is the maiden issue of Zamani: A Journal of African Historical Studies. It charts the beginning of a continental journal that is based in an African higher education institution within Africa. It breaks away from the traditional historical journals in Africa of being national or regional and at best being owned and operated by scholars and institutions from Europe and North America. With this maiden issue, the journal seeks to demonstrate that it is part of the bigger knowledge decolonization movement. It seeks to influence historical writing and research by giving more Africanness in ownership, operations, production and knowledge …
Medical Mission Futures: German Protestant Missionaries And Modern Healthcare In Southern Highlands, Tanzania,1891–1940, Luoneko Kaduma
Medical Mission Futures: German Protestant Missionaries And Modern Healthcare In Southern Highlands, Tanzania,1891–1940, Luoneko Kaduma
Zamani: A Journal of African Historical Studies
The history of colonial missionaries in Tanzania is marked by a complex interplay between evangelical efforts and the provision of Western biomedicine, which functioned as crucial mechanisms for conversion and cultural transformation. Missionaries viewed the improvement of African health as a project aimed at attracting converts and propagating Christianity. However, the available data indicates that, instead of genuinely expressing interest in converting to Christianity, the majority of Africans primarily sought mission medical assistance for medical reasons while maintaining strong connections to their traditional beliefs and healing practices. This paper, drawing from archival documents, ethnographic accounts, and missionary writings, focuses on …
‘Prevention Is Better Than Cure’: Smallpox Vaccination In Postcolonial Tanzania, 1961–1980, Musa Sadock
‘Prevention Is Better Than Cure’: Smallpox Vaccination In Postcolonial Tanzania, 1961–1980, Musa Sadock
Zamani: A Journal of African Historical Studies
This article examines the smallpox vaccination programme in postcolonial Tanzania from the 1960s to the early 1980s as part of the postcolonial future making in preventive medicine. The article departs from extant scholarship on smallpox vaccination in postcolonial Tanzania, which depicts the intervention as a success, while relegating to the background challenges associated with the intervention. The article argues that the smallpox vaccination programme registered challenges and successes that offer lessons for combating of future epidemics. The achievements of the programme were due to the adoption of specific public health policies, namely mass vaccination and public health education as well …
