The flexible pads are called base-isolators, whereas the structures protected by means of these devices are called base-isolated buildings. The main feature of the base isolation technology is that it introduces flexibility in the structure.

The Bronsted-Lowry theory doesn't go against the Arrhenius theory in any way-it just adds to it. Hydroxide ions are still bases because they accept hydrogen ions from acids and form water.
