Perhaps you should try some spelling variations:
le developpement » de developpement, sme development
developpement l » developpement il, developpement la, developpement de
des variation » does variation, de variation, der variation
variation im » variation _, variation 6, variation des
l afrique » en afrique
does cat » does cash, does city, does a
a le » a les, a la, a l
typologie » typologies, typology

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: "typologie des variation im ((does data) OR (does cat)) communication a le developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie des variation im ((does data) OR (does cat)) communication a le developpement l afrique.*.
