Another passive process is osmosis. This is the process by which water crosses a cell membrane either into or out of the cell, but always into the solution that has the higher total concentration of solutes. Dr Aziz.
The flying buttress is the defining external characteristic of gothic architecture. These buttresses act to spread the weight of the tall walls. They support the structure by transferring force directly to the ground. The flying buttress was not just practical, though.
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall.[1] Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of the roof structures that lack adequate bracing. The term counterfort can be synonymous with buttress, and is often used when referring to dams, retaining walls and other structures holding back earth.
