Perhaps you should try some spelling variations:
developpement l » developpement il, developpement la, developpement de
de variation » der variation, die variation, does variation
typology de » typology _, typology 6, typology a
l afrique » en afrique
der mass » der massen, der maske, over mass
3 der » 2 der
3 de » 3 die, 3 des, _ de

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 de variation _ der mass communication ((3 de) OR (3 der)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology de variation _ der mass communication ((3 de) OR (3 der)) developpement l afrique.*.
