Perhaps you should try some spelling variations:
communicating topic » communicating your, communicating model
developpement en » developpement et, developpement des, developpement de
2 developpement » de developpement, le developpement, et developpement
typologies et » typologie et, typologies art, typologies _
variation das » variation des, variation data, variations des
et variation » der variation, bei variation, 2 variation
topic 2 » topic _, topic 1, topics _
dem im » dem iv
dem i » dem iv, dem _, dem 2

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: "typologies et variation das ((dem i) OR (dem im)) communicating topic 2 developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologies et variation das ((dem i) OR (dem im)) communicating topic 2 developpement en afrique.*.
