The movement of a solvent through a membrane separating two solutions of different concentrations. The solvent from the side of weaker concentration usually moves to the side of the stronger concentration, diluting it, until the concentrations of the solutions are equal on both sides of the membrane.

Federation Square is a mixed-use development in the inner city of Melbourne, covering an area of 3.2 hectares and centred on two major public spaces: open squares (St. Paul's Court and The Square) and one covered (The Atrium), built on top of a concrete deck above busy railway lines.n 2009, Virtual Tourist awarded Federation Square with the title of the 'World's Fifth Ugliest Building'. Criticisms of it ranged from its damage to the heritage vista to its similarity to a bombed-out war-time bunker due to its army camouflage colours.
