Perhaps you should try some spelling variations:
csr communication » de communication, 3 communication, 4 communication
developpement de » developpement des, developpement durable
typologie does » typologie des, typologie der, typologie cices
does variation » de variation, der variation, die variation
variation bei » variation des, variation der, variation _
de afrique » de l'afrique, en afrique, l afrique
der csr » does csr

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 does variation bei der csr communication ((2 its) OR (_ its)) developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie does variation bei der csr communication ((2 its) OR (_ its)) developpement de afrique.*.
