INTRODUCTION The National Advisory Committee on Aeronautics' (NACA) severity score is widely used in pre-hospital emergency medicine to grade the severity of illness or trauma in patient groups but is scarcely validated. The aim of this study was to assess the score's ability to predict mortality and need for advanced in-hospital interventions in a cohort from one anaesthesiologist-manned helic...

Sodium overload of cardiac cells can accompany various pathologies and induce fatal cardiac arrhythmias. We investigate effects of elevated intracellular sodium on the cardiac action potential (AP) and on intracellular calcium using the Luo-Rudy model of a mammalian ventricular myocyte. The results are: 1) During rapid pacing, AP duration (APD) shortens in two phases, a rapid phase without Na(+...

Diesel exhaust particles (DEPs), a by-product of diesel engine exhaust (DEE), are one of the major components of air borne particulate matter (PM) in the urban environment. DEPs are composed of soot, polycyclic aromatic hydrocarbons (PAHs), redox active semi-quinones, and transition metals, which are known to produce pro-oxidative and pro-inflammatory effects, thereby leading to oxidative stres...

At the present time many wind power plants have been developed in mountainous areas, off-shore sites also at high latitudes and however operating harsch climate or aggressive environment conditions. In these conditions HAWT’s rotor blades may experiment erosion, corrosion, exfoliation icing operative cause a remarkable aerodynamical performance decay resulting reduction energy production due to...

A new two-equation Kinetic-Eddy Simulation (KES) model is developed for large-eddy simulation (LES) of wall-bounded high Reynolds number flows. This model solves for the local unresolved kinetic energy and the local length scale. The dissipation of the kinetic energy depends on the length scale, as well as, on the length scale gradient. New terms of subgrid viscous work, subgrid pressure diffus...

Department of Aeronautical and Astronautical Engineering. University of Illinois at Urbana-Champaign. 306 Talbot Laboratory. 104 S. Wright Street. Urbana. IL 61801-2935 In a continuing effort to enhance the performance of small wind energy systems, one root airfoil and three primary airfoils were specifically designed for small horizontal axis wind turbines. These airfoils are intended primaril...

Free radical production and, consequently, oxidative stress play an important role in the pathogenesis of AIDS and cause damage to lipids, proteins, and DNA. In our previous study, the HIV-1 envelope glycoprotein (gp120) and transregulatory protein (Tat) of HIV-1 have been found to induce oxidative stress in an immortalized endothelial cell line from rat brain capillaries, RBE4 (in vitro model ...

We propose a steady-state aerodynamic data-driven method to predict the incompressible flow around airfoils of NACA (National Advisory Committee for Aeronautics) 0012-series. Using Signed Distance Function (SDF) parameterize geometric and condition setups, prediction core is constructed essentially by consecutive framework convolutional neural network (CNN) deconvolutional (DCNN). Impact traini...

A recently developed mixing length model of the turbulent shearing stress in wall bounded flows has been used to formulate a universal velocity profile (UVP) that provides an effective replacement for widely Coles wall-wake formulation. Comparisons with both direct numerical simulation and experimental data demonstrate ability approximate wide variety wall-bounded flows. The UVP is uniformly va...
