This paper is devoted to the robust optimization of nacelle liners (acoustic treatments). The full computational aeroacoustic model based on convected Helmholtz equation in presence a nonhomogeneous flow velocity field, which computed by solving potential Euler equations. Uncertainties are taken into account order increase robustness predictions. A reduced-order constructed implement nonparamet...

Using low permeability soils in landfill liners is a guaranteed leachate control and prevents leakage which causes environmental pollution. In this matter, the application of new technologies such as nano provides more capable filters that are used for reducing pollutants modifying geotechnical properties liners. The presented study attempted to conduct experimental research on nanoclay–nanofib...

The use of liners to maintain the vitality and health dental pulp is an effective method in operative dentistry, which involves placing a protective layer liner on exposed stimulate dentin cells make reparative dentin. for has been used many years considered essential part restorative procedures dentistry textbooks. Liners have traditionally protect from potentially toxic effects different irri...

Outflows play a major role in the evolution of galaxies. However, we do not have yet complete picture their properties (extension, geometry, orientation and clumpiness). For low-luminosity Active Galactic Nuclei (AGNs), particular, low-ionisation nuclear emission line regions (LINERs), rate outflows are largely unknown. The main goal this work is to create largest, up-to-date atlas ionised gas ...

Geosynthetic clay liners (GCLs) play a major role in optimising the hydraulic performance of today’s barrier systems. Numerous researches have been carried out to evaluate and enhance hydraulic...
