Perhaps you should try some spelling variations:
communication model » communication media
1 developpement » de developpement, le developpement, et developpement
developpement l » developpement il, developpement la, developpement de
technologies 2 » technologies _, technologies 4
l afrique » en afrique
1 ice » _ ice, 1 ict, r ice
3 ice » _ ice, 3 ict, r ice

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 2 innovation ((1 ice) OR (3 ice)) mass communication model 1 developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 innovation ((1 ice) OR (3 ice)) mass communication model 1 developpement l afrique.*.
