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.
We manage Trafalgar Square, one of Londonâs most vibrant spaces in the middle of the city. Find out about the history of this heritage site, its statues and its fountains.
After that itâs London sightseeing 101 as Baker St, Oxford St, Regentâs St and Picadilly Circus are gobbled up in quick succession. Well, depending on the traffic obviously. This is very much your basic sightseeing and shopping tour bus. Few frills, but it gets the job done. Number 29: Wood Green -> Trafalgar Sq. Passing the Emirates is always cool, then head on into Camden where you can gawp at the freaks/marvel at the self-expression on show, and maybe hop off for a quick pint.
