I need a mathematical or a physical calulation about this large subject, but I do not find anyone, I think that you can help me. I would be grateful to you if you could send to me such a calculation (not necessary a very complicated one neither a long one). It is very important for my future but it is urgent. I would be grateful to you. Olivier
