Perhaps you should try some spelling variations:
time communication » de communication, mobile communication, online communication
a developpement » au developpement, de developpement, le developpement
developpement l » developpement il, developpement la, developpement de
technologies 3 » technologies _, technologies 4, technologies 2
3 formulation » _ formulation, _ formulating
l afrique » en afrique
3 fine » _ fine, 4 fine, 3 fire
a fine » _ fine, a five, a finite

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 3 formulation ((3 fine) OR (a fine)) time communication _ a developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 3 formulation ((3 fine) OR (a fine)) time communication _ a developpement l afrique.*.
