Research ArticleOpen accessIn the abstractNumerical Analysis of Pulsatile Blood Flow in a Stented Human Coronary Artery with a Flow DividerVahab Dehlaghi, Mohammad Tafazoli Shadpoor, Siamak NajarianShear stress is known to play a central role in restenosis formation and is sensitive to stent geometry. Local flow alterations created by a different stents without and with flow divider were studied to compare the hemodynamic effects of Stent design properties on restenosis in stented human coronary artery. Blood pressure and shear stress values were computed in three different … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,521 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOn the Stability of the Triangular Lagrangian Equilibrium Points in the Relativistic Restricted Three-Body ProblemM. K. Ahmed, F.A. Abd El-Salam, S.E. Abd El-BarThe restricted three body problem is treated in the framework of the post-Newtonian approximation of general relativity. The equations of motion are linear zed around the libration points L4,5. Locations of the equilibrium points L4,5 are obtained. Existence and stability of these points are investigated. The relativistic correction to the classical mass ratio is determined. …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 7,303 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Brief Tour into the History of Gravity: From Emocritus to EinsteinPanagiotis Papaspirou, Xenophon MoussasThe History of Gravity encompasses many different versions of the idea of the Gravitational interaction, which starts already from the Presocratic Atomists, continues to the doctrines of the Platonic and Neoplatonic School and of the Aristotelian School, passes through the works of John Philoponus and John Bouridan and reaches the visions of Johannes Kepler and Galileo Galilei. Then, the major … …Space Science International, Vol. 1, Issue 1 · 20 Jun 2013 · 15,084 accessesView PDF Cite
