Perhaps you should try some spelling variations:
based communication » brand communication, based compensation, mediated communication
der developpement » de developpement, des developpements, leur developpement
a information » 2 information, 1 information
technology a » technology 1, technology 3, technology 4
des afrique » en afrique, de l'afrique
a abs » 1 abs, 3 abs, 5 abs

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: "technology a information ((a abs) OR (2 abs)) based communication _ der developpement des afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology a information ((a abs) OR (2 abs)) based communication _ der developpement des afrique.*.
