Hey all, Karp, here are some of the references I have gathered for the aeration step that may be handy for you for detailed design. Also what time is everyone available thursday and friday to work on the presentations? I will be going to the other groups on thursday morning to get some ideas and how things are run and then i am free from then on. It will probably be a good idea to get cranking on the presentation then. Jake we will email you to let you know if we need you to whip up some slides. Cheers, Matt
