Perhaps you should try some spelling variations:
zur developpement » leur developpement, du developpement, au developpement
developpement la » developpement de, developpement et, developpement du
communication 1 » communication _, communication a, communication 3
technologies 1 » technologies _, technologies 4, technologies 2
la afrique » l afrique, la fabrique, en afrique
b top » 1b top, _ top, 3 top
a top » _ top
mass » maps

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 1 information ((b top) OR (a top)) mass communication 1 zur developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 1 information ((b top) OR (a top)) mass communication 1 zur developpement la afrique.*.
