Perhaps you should try some spelling variations:
sciences integration » sciences integrating, science integrating, science interaction
science integration » science integrating, science emigration, science information
facilitation » facilitating, facilitate, facilitated

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: facilitation sociale ((((sciences integration) OR (science integration))) OR (science international))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "facilitation sociale ((((sciences integration) OR (science integration))) or (science international))*".
