Perhaps you should try some spelling variations:
5.4 communication » de communication, data communication
de developpement » sme development
developpement l » developpement il, developpement la, developpement de
typologien der » typologie der, typologie des, apologien der
der variation » de variation, does variation, die variation
l afrique » en afrique
6 does » 16 does, 2 does, 1 does
4 does » 2 does
a de » a die, a der, a des

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: "typologien der variation ((6 does) OR (4 does)) 5.4 communication a de developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologien der variation ((6 does) OR (4 does)) 5.4 communication a de developpement l afrique.*.
