Zinc And Bismuth Additives' Impacts On The Physical Properties Of Lead-Free Alloys Used In Electronic Appliances, Hesham Elzanaty, Rizk Mostafa Shalaby

Mansoura Engineering Journal

The goal of the current analysis was to analytically inspect how the addition of zinc and bismuth would alter the binary structure of the lead-free solder Sn-5Sb. Binary arrangement results have been stretched to the ternary arrangements Sn–5Sb–XBi or XZn (0 ≤ X ≤ 4wt.%) solder that were composed through rapid solidification processing (RSP) using the melt–spun method. The created phases were revealed through metallographic study of the formed alloys using XRD. High elastic modulus E = 32.5 GPa and good electrical resistivity = 26x10-8 .m are two characteristics of binary Sn-Sb doped with Bi. The alloy Sn–5Sb–4Zn owns the …

Watson, Zachary Radford, Hayley Bannister, Robin Bradley, Mary Brown, Benjamin J. Ciotti, Derek Goodwin, Jennifer A. Graham, Richard D.M. Nash, William K. Roche, Ciara Wogerbauer, Kieran Hyder

School of Biological and Marine Sciences

Year class strength is an important determinant of fish population size, but the drivers are often unknown. The northern stock of European sea bass (Dicentrarchus labrax) is an important target species for both commercial and recreational fisheries. Scientific assessments showed a rapid decline in spawning stock biomass from 2010-18 attributed to a combination of fishing mortality and poor year class strength. Recruitment to the adult stock is linked to the abundance and temporal dynamics of young bass in estuarine nursery areas, but little is known about the relative importance of environmental and biological drivers on the survival of these young …

Temporal Changes In The Surface Chemistry And Topography Of Reactive Ion Plasma-Treated Poly(Vinyl Alcohol) Alter Endothelialization Potential, Ryan A. Faase, Novella M. Keeling, Justin S. Plaut, Christian Leycam, Gabriela Acevedo Munares, Monica T. Hinds, Joe E. Baio, Patrick L. Jurney

Faculty Research, Scholarly, and Creative Activity

Synthetic small-diameter vascular grafts (<6 mm) are used in the treatment of cardiovascular diseases, including coronary artery disease, but fail much more readily than similar grafts made from autologous vascular tissue. A promising approach to improve the patency rates of synthetic vascular grafts is to promote the adhesion of endothelial cells to the luminal surface of the graft. In this study, we characterized the surface chemical and topographic changes imparted on poly(vinyl alcohol) (PVA), an emerging hydrogel vascular graft material, after exposure to various reactive ion plasma (RIP) surface treatments, how these changes dissipate after storage in a sealed environment at standard temperature and pressure, and the effect of these changes on the adhesion of endothelial colony-forming cells (ECFCs). We showed that RIP treatments including O2, N2, or Ar at two radiofrequency powers, 50 and 100 W, improved ECFC adhesion compared to untreated PVA and to different degrees for each RIP treatment, but that the topographic and chemical changes responsible for the increased cell affinity dissipate in samples treated and allowed to age for 230 days. We characterized the effect of aging on RIP-treated PVA using an assay to quantify ECFCs on RIP-treated PVA 48 h after seeding, atomic force microscopy to probe surface topography, scanning electron microscopy to visualize surface modifications, and X-ray photoelectron spectroscopy to investigate surface chemistry. Our results show that after treatment at higher RF powers, the surface exhibits increased roughness and greater levels of charged nitrogen species across all precursor gases and that these surface modifications are beneficial for the attachment of ECFCs. This study is important for our understanding of the stability of surface modifications used to promote the adhesion of vascular cells such as ECFCs.

Chronic kidney disease is a leading cause of death and disability globally and impacts individuals of African ancestry (AFR) or with ancestry in the Americas (AMS) who are under-represented in genome-wide association studies (GWASs) of kidney function. To address this bias, we conducted a large meta-analysis of GWASs of estimated glomerular filtration rate (eGFR) in 145,732 AFR and AMS individuals. We identified 41 loci at genome-wide significance (p < 5 × 10−8), of which two have not been previously reported in any ancestry group. We integrated fine-mapped loci with epigenomic and transcriptomic resources to highlight potential effector genes relevant to kidney physiology and disease, and reveal key regulatory elements and pathways involved in renal function and development. We demonstrate the varying but increased predictive power offered by a multi-ancestry polygenic score for eGFR and highlight the importance of population diversity in GWASs and multi-omics resources to enhance opportunities for clinical translation for all.

Development Of A Xenograft For Annular Repair Using Pulsed Electric Field Exposures For Enhanced Decellularization, Prince Mensah Kwaku Atsu

Theses and Dissertations

Severe back injuries and chronic pain necessitate surgical replacement of damaged intervertebral disc (IVD) cartilage in advanced disease stages. Bovine IVD tissue has been exposed to an upper threshold pulsed electric field (PEF) dose, causing cell death without thermal damage to the tissue. Subsequent PEF exposures at lower magnitudes have accelerated the removal of immunogenic biomolecules though electrokinetic extraction using optimized aqueous solutions. This approach yields a natural scaffold, ready for biocompatibility and mechanical strength assessment. The effects of microsecond pulsed electric fields (µsPEF) on primary bovine AF fibroblast-like cells have been characterized in vitro. PEFs of 10 and 100 …

The “Integrality” Of Integral Ecology, Jojo M. Fung

Landas

The Integrality of Integral Ecology calls for a rejection of the technocratic paradigm in favor of the relational paradigm that foregrounds the interbeingness of all humankind and other kinds rooted in their inherent values. This relational paradigm advocates the intersectional relations of cultural, economic, social, political ecology, spiritual ecology, and the ecology of daily life. This integrality is grounded in an incarnational theology that the God who has “earthyfied” Godself has sacralized and “eternalized” our common home. In Asia, this integrality is enriched by the Indigenous/Igorot’s earth spirituality, which identifies Kabunian, land, identity, being, and life as a sacred whole, …

Accidental Outreach And Happenstance Staffing: A Cross-Institutional Study Of Writing Center Support Of First-Generation College Students, Beth A. Towle

The Writing Center Journal

First-generation students (FGS) make up a significant percentage of college populations. However, they experience hardships that are less common for their continuing-generation peers. They struggle to understand the “rules” of college and lack the cultural capital that can help students succeed through generations of knowledge about how to navigate college. Writing centers attempt to lessen these burdens by providing outreach to marginalized student populations, including FGS. However, there has been a lack of cross-institutional research that examines exactly how writing centers support FGS. This article presents a mixed-methods study that begins to close that knowledge gap and demonstrate common patterns …

Earth Art In The Great Acceleration: Times/Counter-Times, Monuments/Counter-Monuments, Gary Shapiro

Philosophy Faculty Publications

This article attempts to situate land art in the deserts of the US Southwest in terms of the works’ relation to and rupture with more traditional genres (seventeenth to twentieth centuries) of parks, gardens, and landscape architecture. It argues that the earlier works provide implicit answers to questions concerning Earth’s meaning and offer models of flourishing habitation. In contrast, the more recent works, all constructed in the era of the great acceleration (the Anthropocene), pose questions having to do with new challenges posed by climate change and the devastation of the Earth.
