technologies b » technologies _, technologies 4, technologies 2
b informations » b information, 2 informations, 3 informations
l afrique » en afrique

de 2 » des 2, der 2, de 20
a le » a les, a la, a l

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 b informations tirer ((de 2) OR (dem 2)) communication a le developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies b informations tirer ((de 2) OR (dem 2)) communication a le developpement l afrique.*.
