TLDR
The mathematical model clearly shows that the increase in wall shear stress affects the aggregation of human platelets and rearranging the alignment of endothelial cells near the arterial wall, which reduces the amount of blood supply to the vital organs which ultimately leads to a sudden death.About:

Parameters estimation of three-phase induction motors using differential evolution
Jacqueline Jordan Guedes,Marcelo Favoretto Castoldi,Alessandro Goedtel,Cristiano M. Agulhari,Danilo Sipoli Sanches +4 more
TL;DR: In this article, the authors proposed a method based on the differential evolution algorithm, aimed at the estimation of the electrical and mechanical parameters of three-phase induction motors, which is capable of estimating the parameters of the equivalent electrical circuit, such as stator and rotor resistances and leakage inductances, the magnetizing inductance, and also mechanical parameters such as moment of inertia and the friction coefficient.

Investigation of the plaque morphology effect on changes of pulsatile blood flow in a stenosed curved artery induced by an external magnetic field
TL;DR: In this article, the effect of an external magnetic field on the pulsatile blood flow in a stenosed curved artery to identify a safe magnetic field was investigated and the effects of a number of parameters, including the magnetic susceptibility of blood in oxygenated and deoxygenated states and the magnetic field strength were studied.

Role of a structural parameter in modelling blood flow through a tapering channel
N. Shahid,N. Shahid +1 more
TL;DR: In this article, an investigation of thixotropic parameter influence on blood flow in a stenosed tapered vessel has been carried out by means of analytical and numerical methods, and it has been shown that the variation of a parameter in a range $[0, 1]$, chosen following the evolution of transient shear, flows with time in this particular range and impacts the dynamics of an unsteady, non-Newtonian fluid flow.

Controlling the blood flow in the stenosed porous artery with magnetic field
TL;DR: In this article, the effects of the magnetic field and the permeability of the stenosed artery on the blood velocity were studied and the results showed that the magnetic fields affected the flow field significantly.

Effects of porosity in four-layered non-linear blood rheology in constricted narrow arteries with clinical applications.
S Afiqah Wajihah,D. S. Sankar +1 more
TL;DR: In this paper, a four-layered fluid model is developed to analyse the rheological elements of blood when it flows via constricted arteries with slight constriction and the arterial wall is considered as porous medium.

Acute Vascular Endothelial Changes Associated with Increased Blood Velocity Gradients
TL;DR: The purpose of this study is to quantify the acute changes in endothelial histology that are associated with an induced increase in blood velocity and to establish the “normal” endothelial cell population density as a function of stress exposure.

Flow characteristics in models of arterial stenoses. II. Unsteady flow.
Donald F. Young,Frank Y. Tsai +1 more
TL;DR: It is shown that three dimensionless parameters can be used to characterize the unsteady flow in a stenosis and the effect of unsteadiness is investigated experimentally using axisymmetric and nonsymmetric models.
