Here, we developed a novel and facile method to control the local water adhesion force of a thin and stretchable superhydrophobic polydimethylsiloxane (PDMS) substrate with micro-pillar arrays that allows the individual manipulation of droplet motions including moving, merging and mixing. When a vacuum pressure was applied below the PDMS substrate, a local dimple structure was formed and the wa...

Divertor monitoring pulses (DiMPle) have been run in JET from the C35 campaign onwards. They provide an opportunity to study impurity contamination of plasma when it is limited by different surfaces within machine, as well longer term behaviour impurities. In these discharges first on outer wall, then inner wall and, subsequently, X-point configuration strike point positioned horizontal tile 5 ...

The applicability of the solution unsteady Reynolds-averaged Navier–Stokes equations (URANS) for numerical simulation periodic quasi-switching regime vortex generation and heat transfer in a deep conical dimple with slope angle 10∘ on wall narrow channel is substantiated. To calculate turbulent regime, model shear stress by Menter 2003, modified taking into account influence curvature streamlin...

The nonlinear axisymmetric post-buckling behaviour of perfect, thin, elastic spherical shells subject to external pressure and their asymmetric bifurcations are characterized, providing results for a structure/loading combination with an exceptionally nonlinear buckling response. Immediately after the onset of buckling, the buckling mode localizes into a dimple at the poles. The relations among...

MR was helpful in demonstrating the spatial relationship between a dermoid cyst in the fourth ventricle and an occipital dermal sinus. T1-weighted images clearly showed the mixed hypointense mass in the fourth ventricle and above the vermis, which appeared to be connected to an occipital dermal dimple.

Oiscussed in the paper is the mixed scenario of charged liquid surface reconstruction when the surface 20 charge density is c1o$e to the saturation . The basic building block of the arising honeycomb structure is shown to be a modifie multielectron dimple.
