Perhaps you should try some spelling variations:
la communication » data communication, data communications
au developpement » du developpement, de developpement, le developpement
developpement en » developpement et, developpement des, developpement de
typologie de » typologie des, typologie der, typologien der
de variation » der variation, die variation, does variation
ban does » behn does, plan does, sun does
far does » der 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) OR (far does)) la communication a au developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie de variation ((ban does) OR (far does)) la communication a au developpement en afrique.*.
