Perhaps you should try some spelling variations:
developpement en » developpement et, developpement des, developpement de
a communication » la communication, data communication, data communications
variation im » variation _, variation 6, variation des
doner a » dorner a, done a
a der » _ der, 2 der, 1 der
3 der » _ der, 2 der
apologia » apologies, apology

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: "apologia _ variation im doner a communication ((a der) OR (3 der)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: apologia _ variation im doner a communication ((a der) OR (3 der)) developpement en afrique.*.
