This article presents the effect of 1%, 3% and 5% content of nano-TiO2 (NT) on the fresh, hardened, microstructural and corrosion Binocular Harness resistance properties of cementitious composites under different exposure environments (tap water, saline water and acidic solution).Various investigations such as setting time, compressive strength, sc
Combining the sol-gel method for fiber material production with the granulated silica method for preform assembly results in a robust method that offers a high degree of freedom regarding both the composition and the geometry of the produced fiber.Using this method, two types of Yb-doped silica glass composition, that feature an excess in P concent
Lubricating grease has increased thermorheological properties during heating, which may affect the lubrication of the friction pair.And a friction pair usually heats up in the working process.This study explored the effect of surface temperature of the friction pair on the lubrication performance under lubrication conditions.The thermorheological p
The Arabian Gazelle is a globally threatened antelope (Vulnerable) in Saudi Arabia.Small relict populations remain in limited areas, while historically Arabian Gazelles occurred in Mahazat as-Sayd protected area in central Saudi Arabia but were exterminated by anthropogenic and other pressures, including habitat loss and hunting.Important habitat h
