Perhaps you should try some spelling variations:
du developpement » de developpement, le developpement, et developpement
developpement il » developpement de, developpement et, developpement du
a communication » la communication, data communication, data communications
typologie der » typologie des, ideologie der
il afrique » l afrique, en afrique
und does » guns does, und doch, cd does
aid does » card does, aid days, aid do
a du » a d, a de, a u
variablen » variables, variable

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 der variablen ((und does) OR (aid does)) a communication a du developpement il afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie der variablen ((und does) OR (aid does)) a communication a du developpement il afrique.*.
