Perhaps you should try some spelling variations:
technologies case » technologies based, technologies can, technologies create
case formulation » basic formulation, chain formulation, space formulation
de communication » mobile communication, online communication
developpement en » developpement et, developpement des, developpement de
does de » does debt
r le » rh le, 1 le, 5 le
3 le » 3 les, 3 la, 1 le

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 case formulation _ does de communication ((r le) OR (3 le)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies case formulation _ does de communication ((r le) OR (3 le)) developpement en afrique.*.
