Perhaps you should try some spelling variations:
des developpement » des developpements, de developpement, le developpement
developpement de » developpement des, developpement durable
i communication » ii communication, ai communication, 3 communication
des variation » does variation, de variation, der variation
ddr i » ddr im, dr i, ddr 1
a des » a der, a das

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 OR typologies) des variation _ ddr i communication a des developpement de l'afrique.~".
• Adding a wildcard symbol may retrieve word variants: (typologie OR typologies) des variation _ ddr i communication a des developpement de l'afrique.*.
