The covalent grafting of alkyl gallates on wool through a laccase catalysed reaction in 80/20 (v/v, %)aqueous–ethanol mixture provided in a one-step process a multifunctional textile material with antioxidant, antibacterial ...

We investigate the effects of an externally imposed axial mass flux [1, 2] (axial pressure gradient, axial through flow) on ferrofluidic Taylor-Couette flow under the influence of either an axial or a transverse magnetic ...

The alkali-aggregate reaction and the internal sulfate attack are two chemical reactions that lead to expansions in concrete structures. The former is one of the main causes of expansions in concrete dams and has been ...

Effects of attached blade cavitation on the natural frequencies of a Francis runner

Axial forces affect the shear strength of concrete members. The estimation of such effects on the shear strength depends on how the axial force influences the various shear transfer mechanisms, since a very different ...
