Low-Reynolds Mathematical Modeling of the Structure of Vortex Zones Between Periodic Surface-Located Flow Turbulators of Semicircular Cross-Section in Pipes by  Lobanov IE in  Surgical Medicine Open Access Journal Mathematical modeling of the structure of vortex zones between periodic surface-located flow turbulators of a semicircular and square cross-section is carried out on the basis of multi-block computational technologies based on the solution of the factorized finite-volume method of the Reynolds equations (closed with the help of the Menter shear stress transfer mode) and the energy equation (on different-scale intersecting structured grids). This method was previously successfully applied and verified by experiment. An exhaustive analysis of the corresponding streamlines is presented, proving the advantage of abruded turbulators. https://crimsonpublishers.com/smoaj/fulltext/SMOAJ.000579.php For more Open access journals in Crimson Publishers Please click on:  https://crimsonpu

 The Impact of Age Structure of a Country in Case Fatality of Covid-19 by Anish TS in Surgical Medicine Open Access Journal The SARS-CoV 2 pandemic, since its origin in China as a cluster of pneumonia cases, had reached almost every part of the world and had killed more than one million people worldwide [1]. The case fatality differs substantially between countries along with the number of symptomatic patients, sequelae of the disease and those who require intensive lifecare support. Such a perceived difference can be attributed to macroecological dissimilarities like the general well-being of the population and a more extent, its demographic structure. The demographic characteristics, most notably the age structure and population density, has important implications in the spread of infectious diseases [2,3]. https://crimsonpublishers.com/smoaj/pdf/SMOAJ.000578.pdf For more Open access journals in Crimson Publishers Please click on:  https://crimsonpublishers.com/   For more Articl
