Perhaps you should try some spelling variations:
developpement en » developpement et, developpement des, developpement de
au developpement » du developpement, de developpement, le developpement
variation ban » variation bei, variation a, variation von
typologie de » typologie des, typologie der, typologien der
de variation » der variation, die variation, does variation
does la » does lac, does law, does ea
does a » does _
a au » a auf, a bau, a aus

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