Perhaps you should try some spelling variations:
developpement en » developpement et, developpement des, developpement de
ou developpement » du developpement, au developpement, de developpement
a communication » la communication, data communication, data communications
typologie de » typologie des, typologie der, typologien der
de variation » der variation, die variation, does variation
behn does » being does
ban does » plan does, far does, sun does
a ou » a o, a u, a su

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 de variation ((ban does) OR (behn does)) a communication a ou developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie de variation ((ban does) OR (behn does)) a communication a ou developpement en afrique.*.
