The Influence of the Reynolds Number on the Auto-Rotation of Samaras
As samara seeds fall from trees, they enter into auto-rotation. In this way they maximize dispersal distances (Green, Am J Bot 169:1218–1224, 1998, [2]). In this study, we present direct numerical simulations of ...

Primary wound closure with a Limberg flap vs. secondary wound healing after excision of a pilonidal sinus: a multicentre randomised controlled study
Off-midline procedures seem to be the best method of primary wound closure after excision of a pilonidal sinus. Primary wound closure with a Limberg flap was compared to secondary wound healing.

Direct Numerical Simulation of Vertical Particulate Channel Flow in the Turbulent Regime
We have conducted a DNS study of dilute turbulent particulate flow in a vertical plane channel, considering up to 8192 finite-size rigid particles with numerically resolved phase interfaces. The particle diame...

A computational study of the hydrodynamic forces on a rough wall
The hydrodynamic interaction of a fluid with a rough wall results in a net force on the roughness elements. This can cause erosion of the roughness elements – an important aspect for sediment transport in rive...

The effect of coherent structures on the secondary flow in a square duct
The appearance of secondary flow of Prandtl’s second kind is a well-known phenomenon in fully developed turbulent rectangular duct flow. The intensity of the secondary flow is two orders of magnitude smaller t...

Travelling waves in a straight square duct
Isothermal, incompressible flow in a straight duct with square cross-section is known to be linearly stable [1]. Direct numerical simulation, on the other hand, has revealed that turbulence in this geometry is...

Second Order Entropy Consistent Modelling of Turbulent Compressible Flows
We examine herein the suitability of some second order closures to describe turbulent compressible flows with shocks, applying the standard Favre averaging technique. The basic set of equations reads: ...

Aminoguanidine does not inhibit the initial phase of experimental diabetic retinopathy in rats
We have previously shown that long-term administration of aminoguanidine, an inhibitor of advanced glycosylation product formation, reduces the extent of experimental diabetic retinopathy in the rat by 85%. In...
