Perhaps you should try some spelling variations:
der developpement » de developpement, des developpements, leur developpement
developpement en » developpement et, developpement des, developpement de
communication 3 » communication _, communication a
die variation » de variation, does variation, der variation
typology die » typology _, typology 4.1, typology 6
variation 6 » variation _, variations _, variation des
der 4 » der e, der a, des 4
3 der » _ der, 2 der

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 die variation 6 ((der 4) OR (der _)) communication 3 der developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology die variation 6 ((der 4) OR (der _)) communication 3 der developpement en afrique.*.
