Dear Nick, as I told you I wasn't able to hear properly because the sound was very bad for me and I lost the comunication for some seconds. Is it possible to send me a ressume of what you are talking there by the moment you do it? Anyway I wil be online trying to get the discussions of the conference, if you don't send me some kind of ressume it will be not much clear for me. thank you very much.. Carlos Aguirre
