developpement de » developpement des, developpement durable
communication 1 » communication _, communication a, communication 3
technologies 4 » technologies _
4 information » 2 information, 1 information
1 wie » 1 die, 2 wie, 3 wie
1 we » _ we, 1 le, 1 e
1 au » 1 auf, 1 aug, 1 a

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: "technologies 4 information ((1 we) OR (1 wie)) mass communication 1 au developpement de l'afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 4 information ((1 we) OR (1 wie)) mass communication 1 au developpement de l'afrique.*.
