Enhanced shear adhesion of mechanically interlocked dual-scaled micropillars embedded with silica particles is demonstrated. Arrays of elastomeric polyurethane acrylate micropillars with variable pillar diameter, height, aspect ratio (AR1⁄4diameter/height), and spacing ratio (SR1⁄4pillar-to-pillar distance/diameter) are decorated with silica particles of 100nm to 1mm on the pillar heads. The hi...

Diffractive structures such as pillar gratings are a promising way of coupling light into or out of thin semiconductor devices, for applications in thin film solar cells and light-emitting diodes. In this paper we show that the diffuse transmittance behavior of pillar gratings can be understood using the concept of grating mode interference and that the optimum heights of the grating and an est...

We propose a knowledge framework for garment recommendations, which is based on two pillars. The first pillar incorporates knowledge about aspects of fashion, such as materials, garments, colours, body types, facial features, social occasion etc., as well as their interrelations, with the purpose of providing personalised recommendations. The said knowledge is encoded in the form of an OWL onto...

Microfabrication is actually a collection of technologies which are utilized in making microdevices. Some of them have very old origins, not connected to manufacturing, like lithography or etching. Electroplating is technique adapted to produce micrometre scale structures, as are various stamping and embossing techniques. Micro-Components are required in a range of new products such as medical ...

Polyimide has been widely applied to neural prosthetic devices, such as the retinal implants, due to its well-known biocompatibility and ability to be micropatterned. However, planar films of polyimide that are typically employed show a limited ability in reducing the distance between electrodes and targeting cell layers, which limits site resolution for effective multi-channel stimulation. In ...

A recent experimental pillar extraction project at a UG2 bord-and-pillar mine presented unique opportunity to compile new database. Currently, the South African hard rock mines are designed using Hedley and Grant formula with modified K-value. This empirically derived was developed for uranium in Elliot Lake district of Canada. The use this design pillars Africa is questionable. Very few failur...

B-pillar and rocker are the key force transmission sub-systems of side impact battery electric vehicle (BEV), scholars have studied crashworthiness these body a lot. However, works insufficient on analysis benchmarking models, simulation experiment sub-systems, optimization sub-systems. To make up shortcomings, this work aims to design improve BEV. It presents systematic method The dynamic bend...

Ceratamine A and ceratamine B are heterocyclic alkaloids recently identified in a screen for compounds that arrest cells in mitosis. Treatment of breast carcinoma MCF-7 cells causes a concentration-dependent block of cell cycle progression exclusively at mitosis. In vitro studies with purified tubulin indicate that the ceratamines directly stimulate microtubule polymerization in the absence of ...

Computed tomographic (CT) scans and plain radiographs of 21 patients with surgically treated fractures or dislocations of the cervical spine were reviewed. CT effectively demonstrated the locked or perched facets and half of the 13 articular pillar fractures. The fracture lines through the articular pillar were difficult to detect in some cases or to distinguish from a facet joint in others. Ho...
