Perhaps you should try some spelling variations:
ides development » ads development, does development, smes development
der variation » de variation, does variation, die variation
variation des » variation _, variation 6, variation series
development l » development li, development 1, development law
typology der » typologie der, typologien der, typologie des
l afrique » en afrique
4 power » 3 power

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 der variation des ((4 power) OR (2 power)) communication _ ides development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology der variation des ((4 power) OR (2 power)) communication _ ides development l afrique.*.
