In the recent literature it has been shown that $H_0$ tension may be eliminated if an abrupt physics transition changed Cepheid parameters in near past of Universe, nearly $70-150\,$Myrs ago. this letter we stress possibility was caused by smooth passage our Universe through a pressure finite-time cosmological singularity. Being non-crushing type singularity can leave its imprints since occurs ...
objective: duplex ultrasonography is a non-invasive, non-expensive screening test for carotid disease. intima media thickness (imt) is appropriate for atherosclerosis process diagnosis. leukoaraisis (la) increase the risk of cerebrovascular accident (cva). la patients need preventive medication for cva. imt is a non-invasive diagnostic and prognostic test in la. the aim of this study was evalua...
In this paper, the flow-field of an incompressible viscous flow past a solid-sphere at low Reynolds numbers (up to 270) is investigated numerically. In order to extend the capabilities of the finite volume method, the boundary (body) fitted coordinates (BFC) method is used. Transformation of the partial differential equations to algebraic relations is based on the finite-volume method with coll...
