Perhaps you should try some spelling variations:
developpement il » developpement de, developpement et, developpement du
et developpement » de developpement, le developpement, test development
4 communication » 3 communication, 5.4 communication, de communication
typologie der » typologie des, ideologie der
il afrique » l afrique, en afrique
und does » guns does, aid does, cd does
a et » a set, a net, a bet
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 (und doch)) 4 communication a et developpement il afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie der variablen ((und does) OR (und doch)) 4 communication a et developpement il afrique.*.
