The effects of a typical glaze ice accretion shape on the performance of the M2129 S-duct inlet are computationally investigated for a range of flight Mach numbers. A Reynolds-Averaged Navier-Stokes (RANS) code with k-o> turbulence model is used to simulate the compressible viscous flow in the S-duct inlet. The glaze ice accretion on the cowl lip is modeled on a steady-state basis f rom N A S A...

DESCRIPTION OF WELLCOME TILE* The tile is an elongated octagon in shape. It has a blue tinted glaze, and bright blue decoration with the motto in maroon. The sides of the tile are chamfered, and the glaze on the back is in irregular patches. The design of the Society of Apothecaries' Arms-with ribbon-like scrollwork to the sides of Apollo, who has an unusual 'Red Indian' headdress-is quite dist...

In this work was investigated the feasibility to use Waste Electrical and Electronic Equipment (WEEE) glasses in construction sector as secondary raw material. WEEE glasses were used in different percentages as a function of the product obtained: 30-40wt% for glaze formulations, about 40wt% for glass-ceramics and 5wt% in brick bodies. The laboratory and industrial scale up results demonstrated ...

This study evaluated, in vivo, the efficacy of a denture glazing material (Palaseal) in modifying plaque colonization of dentures. Ten subjects were selected and received maxillary temporary partial removable dentures, with complete acrylic palatal coverage. The right half of the fitting surface of the denture bases were glazed with Palaseal, whereas the other half was not glazed. One month aft...

Ancient Jian wares are famous for their lustrous black glaze that exhibits unique colored patterns. Some striking examples include the brownish colored "Hare's Fur" (HF) strips and the silvery "Oil Spot" (OS) patterns. Herein, we investigated the glaze surface of HF and OS samples using a variety of characterization methods. Contrary to the commonly accepted theory, we identified the presence o...

In situ quantification of localizedweathering processes on basalt flows inNewMexico andHawaii demonstrates that small-area factors can be more important than other more readily observable factors. Further, it demonstrates that the factorial concept of the Pope Boundary-Layer weathering model is partially solvable, that organicweathering can accentuate glassweathering (with implications for clim...

This paper examines two pieces of Ru porcelain glaze excavated from the Qingliangsi kiln site. Compared with R1 glaze, R2 was fired at a lower temperature and cooled slower rate. The chemical composition, microstructure, corrosion mechanisms glazes were analyzed by optical microscopy (OM), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), micro-Raman spectroscopy, tra...

The current research deals with an experimental study in the Crawling Glaze technique under low temperature range (980) degrees Celsius, where a local bentonite clay was used as catalyst to achieve effect of on ceramic surface, and white (Akashat) chosen body for application by adding non-plastic materials such silicic sand grog, well kneading (burnishing) surface be ready this technique, homem...

Shards of Blue-and-White Ming porcelain from shipwrecks Portuguese ships found on the coasts South Africa plus a shard Mombasa (Kenya) were analyzed by optical microscopy, SEM-EDS and Raman microspectroscopy (458 nm). Whereas signature body paste compositions which are based mullite, quartz an amorphous phase with minor presence anatase feldspar very comparable whatever variable alumina content...
