Perhaps you should try some spelling variations:
developpement et » developpement des, developpement de, development east
communication 1 » communication _, communication a, communication 3
a developpement » au developpement, de developpement, le developpement
des variation » does variation, de variation, der variation
typology des » typologie des, typologie der, typology _
et afrique » en afrique, l afrique
der maske » der marke, der markte, der massen
der mass » der massen, over mass, air mass

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: "typology des variation _ ((der mass) OR (der maske)) communication 1 a developpement et afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology des variation _ ((der mass) OR (der maske)) communication 1 a developpement et afrique.*.
