This contribution was made in a special toolbook version which can't be opened with your internet browser without a special intermediate programme. According to the Socrates guidelines and in order to make the work web-compatible, the project co-ordinator decided to contact two engineers who did a very good job in the least expensive way.

Since refund of these costs was denied but respecting the work done by the students of   the Liceo M. Flaminio and taking in consideration the explicite demand of the two engineers who claim copyright for their work, access to these pages is only possible by inserting the right password.
