Research ArticleOpen accessIn the keywordsAnalysis of Blood Turbulent Flow in Carotid Artery Including the Effects of Mural Thrombosis Using Finite Element ModelingM. Arab-Ghanbari, M. M. Khani, A. Arefmanesh, F. Tabatabai-GhomsheArterial thrombosis is an extremely significant health problem. As a result of numerous factors involved in such problem, describing the role of hemodynamics in thrombogenesis has been asserted to be one of the most demanding and complicated challenges in biomechanics. An axisymmetric model considering fluid-structure interactions (FSI) was introduced and numerically solved for an artery with a thrombosis to perform … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,408 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New System to Analyze Pulsatile Flow Characteristics in Elastic Tubes for Hemodynamic ApplicationsAfshin Anssari-Benam, Mohammad Tafazzoli-Shadpour, Nasser Fatouraee et al.In this research, we present a new designed experimental setup for study of characteristics of pulsatile flow in elastic tubes, aiming to simulate arterial blood flow. This system includes four major components: (1) a pulsatile pump producing original arterial flow, (2) an elastic element to simulate coupling of the heart with the arterial system, (3) an elastic tube with mechanical … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,009 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFlow Characteristics in Elastic Arteries Using a Fluid-Structure Interaction ModelH. Niroomand Oscuii, M. Tafazzoli Shadpour, Farzan GhalichiIn this study the interaction of blood flow with arterial wall has been investigated using FSI (Fluid-Structure Interaction) modeling. Computer simulation of pulsatile blood flow was carried out on the basis of the time dependent axisymmetric Navier-Stokes equations for an incompressible Newtonian fluid flow. An elastic incompressible material with large deformation was considered for the arterial wall and momentum and … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,429 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of the Influence of Dust-Salt Aerosols of the Aral Sea on the Morphological Characteristics of the Tissue of the Epididymis of Rats in the ExperimentAssylgul Suleimen, Bibigul Rakhimova et al.Drying of the Aral Sea is a very significant environmental problem of modern times. Dust particles from the dried seabed are spread over long distances and negatively impact the quality of life of residents in nearby areas. One of the significant problems is the decrease in the fertility of residents of the Aral region, but there is insufficient data about … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 24 Jul 2024 · 4,809 accessesView PDFCite
Research ArticleOpen accessIn the abstractNUTRITIONAL CHARACTERISTICS OF THE DAIRY COW DURING EARLY GESTATION AND SUBSEQUENT GROWTH AND CARDIAC MEASUREMENTS OF HER OFFSPRINGJ. E. Larson, B. E. Voelz, D. K. Hardin, C. O. LemleyThe objective was to determine whether maternal nutritional status and milk production during early gestation influenced or were correlated with parameters of the calf at birth and at 1 month of age. From parturition until 90 days pregnant, blood samples were collected every 14 days in dairy cows and plasma was assayed for concentrations of glucose and β-Hydroxybutyrate (BHBA). Calves … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 3 · 15 Sep 2014 · 7,625 accessesView PDFCite
