Perhaps you should try some spelling variations:
de communication » mobile communication, online communication
development en » developpement en, development menu, development eco
der variation » does variation, die variation, zur variation
de variation » die variation, does variation, de validation
des dem » das dem, des der, des des
dem de » dem die, dem der, dem ende
a a » a la

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: "apologien ((der variation) OR (de variation)) des dem de communication a a development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: apologien ((der variation) OR (de variation)) des dem de communication a a development en afrique.*.
