technologies 3 » technologies _, technologies 4, technologies 2
3 formulation » _ formulation, _ formulating

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 3 formulation over ((do 3) OR (do _)) communication a le developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 3 formulation over ((do 3) OR (do _)) communication a le developpement l afrique.*.
