Cementing techniques in hip resurfacing.

The subject of the cementing technique in hip resurfacing has been poorly studied to date. The hip resurfacing prosthesis is unique in the family of cemented prostheses because the cement mantle is blind (hidden underneath the implant) and is radiographically obscured. This presents an immediate challenge to the surgeon at the time of surgery, but also has a longer-term implication in terms of ...

Transient viscoelastic flows in planar contractions

This article considers transient flows for planar contractions and Oldroyd-B fluids, with increasing flow-rate boundary conditions. We employ a novel hybrid finite volume/element time-dependent algorithm. The hybrid scheme consists of a TaylorGalerkin finite element discretisation, and a cell-vertex fluctuation-distribution finite volume approach. These two approaches are coupled at each time-s...

Transient flows in active porous media.

Stimuli-responsive materials that modify their shape in response to changes in environmental conditions-such as solute concentration, temperature, pH, and stress-are widespread in nature and technology. Applications include micro- and nanoporous materials used in filtration and flow control. The physiochemical mechanisms that induce internal volume modifications have been widely studied. The co...

Effects of Restrictive Fluid Management in Transient Tachypnea in Neonates

Background: The transient tachypnea is a common respiratory problem in the neonate. One of the significant issues in pathophysiology of this disorder is the delayed reabsorption of the fluid by the neonate’s lungs and the effusion of fluid in the lungs. The purpose of this study is to evaluate the effects of restrictive fluid management in transient tachypnea of the neonate. Methods: The presen...
