High-density and highly cross-coated anatase TiO2 nanotubes networks have been successfully prepared on the surface of Ti foil by alkaline hydrothermal using NaOH and Ti foil as the precursors.The nanotubes networks were analyzed using X-ray diffraction (XRD), energy dispersive X-ray spectrometer (EDX), transmission electron microscope (TEM), scann
Some buildings have been brought back from Syowa Station in Antarctica after 30 years of use.One was used Western Show Clothing to investigate the combustion properties of the fire retarded plywood which was used in the walls.Full-scale fire behavior/extinguishing tests were carried out using the compartment and a mockup lounge model for the study
The electromagnetic properties of a toroidal coated nanoparticle (T-CNP) antenna with an active core (doped with rare earth erbium Er3+ ions) are investigated.It is demonstrated that the active T-CNP acts as a strong dipole radiator at its resonance frequency when it is excited by a plane wave or an Winterizing Products electric Hertzian dipole (EH
The objective of this investigation is to illustrate the effect of aggregates types and contents on fresh and hardened properties of self-compacting concrete (SCC) considering Algerian experience.Based on experimental data available in the literature, Artificial neural network (ANN) models are established to illustrate the variation of aggregate ty
Cities and migration is a topic which cannot be studied by one discipline, and which is enriched by a multi-level approach.It crosses, inside the area of migration studies, urban studies (geography, political science, and sociology), migration flows and stocks (mobility, settlement, and integration for demographers), public law and international re
