technologien der » technologien des, technologie der, technologien fur
transformation a » transformation _
developing a » developing _
iii die » ii die
iii de » iii der, viii der
a ser » a sber, a set, a sea

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: "technologien der transformation a ((iii de) OR (iii die)) communication costs _ developing a ser.~".
• Adding a wildcard symbol may retrieve word variants: technologien der transformation a ((iii de) OR (iii die)) communication costs _ developing a ser.*.
