Arterial stenosis, for example Atherosclerosis, is one of the most serious forms of arterial disease in the formation of which hemodynamic factors play a significant role. In the present study, a 3-D rigid carotid artery with axisymmetric stenosis with 75% reduction in cross-sectional area is considered. Laminar blood flow is assumed to have both Newtonian and non-Newtonian behavior (generalize...

The rst law of black hole mechanics (in the form derived by Wald), is expressed in terms of integrals over surfaces, at the horizon and spatial in nity, of a stationary, axisymmetric black hole, in a di eomorphism invariant Lagrangian theory of gravity. The original statement of the rst law given by Bardeen, Carter and Hawking for an Einstein-perfect uid system contained, in addition, volume in...

A parallel computational technique is presented for carrying out three-dimensional simulations of parachute  uid-structure interactions, and this technique is applied to simulations of airdrop performance and control phenomena in terminal descent. The technique uses a stabilized space-time formulation of the time-dependent, three-dimensionalNavier–Stokes equations of incompressible  ows for t...

The mixing of Newtonian and non-Newtonian fluids in a magnetic micro-mixer was studied numerically using  ferrofluid. The mixing process was performed in a three-dimensional steady-state micro-mixer. A magnetic source was mounted at the entrance of the micro-channel to oscillate the magnetic particles. The effects of electric current, inlet velocity, size of magnetic particles, and non-Newtonia...

An analytical characterization of forced convective ~ow through a channel _lled with a porous medium is presented in this work[ Based on a two!equation model\ including transverse conduction contributions\ exact solutions are obtained for both ~uid and solid phase temperature _elds[ The Nusselt number is also obtained in terms of the pertinent physical parameters\ namely the Biot number for the...

Stationary perfect uid con gurations of Einstein's theory of gravity are studied. It is assumed that the 4-velocity of the uid is parallel to the stationary Killing eld, and also, that the norm and the twist potential of the stationary Killing eld are functionally independent. It has been pointed out earlier by one of us (I.R.) that for these perfect uid geometries some of the basic eld equatio...

The latest figures on the number of unexplained deaths in infancy for England and Wales in 2008 show that: • There were 281 unexplained infant deaths (UID), a rate of 0.40 deaths per 1,000 live births, the same as in 2007. This accounted for 9 per cent of all infant deaths in 2008. • 79 per cent of all UIDs in 2008 occurred in the postneonatal period (between 28 days and one year). • For babies...
