Effect of body acceleration on unsteady pulsatile flow of non-newtonian fluid through a stenosed artery
TL;DR: The finite difference scheme helps estimating the effects of periodic body acceleration and the non-Newtonian rheology of the flowing blood on the flow velocity, the rate of flow, the wall shear stress and the fluid acceleration through their graphical representations quantitatively at the end of the paper to validate the applicability of the present improved mathematical model under consideration.
Pulsatile Flow of Couple Stress Fluid Through a Porous Medium with Periodic Body Acceleration and Magnetic Field
TL;DR: In this article, an exact solution of the equation of motion is obtained by applying the Laplace and finite Hankel transforms, and expressions for axial velocity, flow rate, fluid acceleration and shear stress have been obtained analytically.

Pulsatile magneto-hydrodynamic blood flows through porous blood vessels using a third grade non-Newtonian fluids model
TL;DR: Drawing important conclusions are that, when the Womersley parameter is low, viscous forces tend to dominate the flow, velocity profiles are parabolic in shape, and the center-line velocity oscillates in phase with the driving pressure gradient.

Slip Effects on the Unsteady MHD Pulsatile Blood Flow through Porous Medium in an Artery under the Effect of Body Acceleration
TL;DR: The obtained results show that the flow is appreciably influenced by the presence of Knudsen number of slip condition, permeability parameter of porous medium, Hartmann number of magnetic field, and frequency of periodic body acceleration.

Ventricular aneurysm: A clinical-pathologic correlation
Roger W. Davis,Paul A. Ebert +1 more
TL;DR: The finding of extensive coronary artery disease in all patients with ventricular aneurysm emphasizes that coronary arteriography should be performed in this group and that revascularization probably should be combined with excision of the dyskinetic segment.

Flow through blood vessels under the action of a periodic acceleration field:A mathematical analysis
J. C. Misra,B.K. Sahu +1 more
TL;DR: In this paper, an analytical study of flow through blood vessels subjected to a periodic acceleration field is devoted to an analytical analysis consisting of two parts, in the first case the wall is treated as a non-linear orthotropic elastic cylindrical membrane and the blood as a Newtonian viscous fluid, while in the second case the experimentally observed material damping properties of the wall tissues and the viscoelasticity of blood have been incorporated in the analysis.

A momentum integral solution for pulsatile flow in a rigid tube with and without longitudinal vibration.
TL;DR: In this paper, a momentum integral solution is obtained for fully developed pulsatile flow in a circular, rigid tube of infinite length using a fourth-order polynomial with unknown coefficients to represent the radial variation of axial velocity across the tube boundary conditions applied at the tube wall and the centerline give the velocity profile in terms of centerline velocity.

Longitudinal Study of the Standard Electrocardiogram in the Healthy Premature Infant During the First Year of Life
TL;DR: All wave durations in the electrocardiograms of healthy premature infants were shorter than those of healthy full-term infants, and the P and QRS vectors were directed more to the left and posteriorly in premature infants than in full- term infants.
