Perhaps you should try some spelling variations:
eu communication » ec communication, et communication, de communication
de developpement » sme development
des variation » does variation, de variation, der variation
typology des » typologie des, typologie der, typology _
des afrique » en afrique, de l'afrique
des dem » des der, des des, des deux
das dem » das der, das den, das drei

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 ((des dem) OR (das dem)) eu communication _ de developpement des afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology des variation ((des dem) OR (das dem)) eu communication _ de developpement des afrique.*.
