Perhaps you should try some spelling variations:
le developpement » de developpement, sme development
developpement du » developpement de, developpement des, developpement et
formulation des » formation des, formulacion de, formulation _
technologies 3 » technologies _, technologies 4, technologies 2
3 formulation » _ formulation, _ formulating
du afrique » en afrique, l afrique, de l'afrique
how de » how doe, how do, how does
how ae » how age, how ai, how am

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 des ((how de) OR (how ae)) communication _ le developpement du afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 3 formulation des ((how de) OR (how ae)) communication _ le developpement du afrique.*.
