Perhaps you should try some spelling variations:
lea's communication » mass communication, crisis communication, leadership communication
development en » developpement en, development menu, development eco
typologie die » typologie des, typologie der, theologie die
die variation » de variation, does variation, der variation
des dem » des der, des des, des deux
das dem » das der, das den, das drei

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: "typologie die variation ((des dem) OR (das dem)) lea's communication _ gas development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie die variation ((des dem) OR (das dem)) lea's communication _ gas development en afrique.*.
