Perhaps you should try some spelling variations:
formulation over » formation over, formulation model, formulation where
developpement en » developpement et, developpement des, developpement de
technologies la » technologies a, technologies le, technologies lead
la formulation » la formulacion, _ formulation, la formation
over do » over de, ever do, over die
r du » _ du, 1 du, 2 du

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 la formulation over do _ communication ((r du) OR (r d)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies la formulation over do _ communication ((r du) OR (r d)) developpement en afrique.*.
