Perhaps you should try some spelling variations:
technologies past » technologies part, technologies pt, technologies art
past information » plant information, cost information, ist information
developpement de » developpement des, developpement durable
information a » information age, information about
de afrique » de l'afrique, en afrique, l afrique
a une » a one
a un » _ un

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 past information a 3 risk communication ((a un) OR (a une)) developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies past information a 3 risk communication ((a un) OR (a une)) developpement de afrique.*.
