Research ArticleOpen accessEvery word in the titleNumerical Study of the Moving Boundary Problem During Melting Process in a Rectangular Cavity Heated from BelowY. Jellouli, R. Chouikh, A. Guizani, A. BelghithWe present an analysis of the melting process in Phase Change Materials (PCM) in a horizontal cavity heated from below, driven by the coupling of transient heat conduction in the solid phase and steady state laminar natural convection in the liquid phase with one of the boundaries of the solution domain that moves. We state the problem in the Cartesian … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,391 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInflammatory Effects of Co-Exposure to Heavy Metals (Cd and Pb) and Respiratory Viruses (229E, OC43, and H3N2) on IL-6 and IL-8 Responses in U87 Glioblastoma CellsHyeokjun Yun, Qian-Wen Wang, Jae Kyung KimCo-exposure to heavy metals and viruses can pose threats to cellular health by increasing cytotoxicity and inflammatory cytokine expression. We aimed to elucidate the interactions between these factors inhuman glioblastoma cells (U87). U87 cells were exposed to influenza A virus (H3N2), coronaviruses OC43 and 229E, and heavy metals Cd and Pb. Cell viability and cytotoxicity were assessed through WST-8 and … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 5 Jul 2025 · 5,505 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Impact of XRF-Escape on Energy Resolution of NaI: Tl Scintillation Detectors for Medical Imaging or Gamma-Ray SpectroscopyRaffaele Scafè, Marco Puccini, Rosanna Pellegrini, Roberto PaniThe effect of escape of X-ray fluorescence from scintillator elemental components on the detector energy resolution is investigated from a spectroscopic standpoint, for monolithic and pixelated crystals. Along with these, any other emissions in a given region of interest were also considered. In present spectral evaluations a range of ratios between the areas of the peaks (XRFesc) to (XRFesc + … …American Journal of Applied Sciences, Vol. 21, Issue 1 · 10 Jul 2024 · 5,024 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFinancing College Through Student Loans: An Incentive for Academic Performance?Gunnar B˚ardsen, Snorre Lindset, Peter ReschStudent debt in the United States has reached unprecedented levels. Whereas student loans have paved the way to a college degree for millions of young Americans, it is not clear if student debt acts an incentive for academic performance or not. Using the results from a survey conducted with 877 undergraduate business students in a large public university in the … …Journal of Social Sciences, Vol. 19, Issue 1 · 24 Aug 2023 · 8,127 accessesView PDF Cite

Review ArticleOpen accessIn the abstractThe Influence of Bedding Application in Feedlot Cattle: A ReviewDathan Thomas Smerchek, Zachary Kidd Foster SmithA sizable portion of cattle on feed in the United States are fed in the Upper Midwest and Northern Plains region where temperatures routinely fall below freezing during late fall, winter and early spring. The persistent cold temperatures coupled with snow accumulation, wind, moisture and ice can cause undesirable pen conditions for confined cattle, ultimately resulting in decreased insulative capacity … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 23 Feb 2021 · 6,718 accessesView PDF Cite
