Perhaps you should try some spelling variations:
der transformation » die transformation, zur transformation, energy transformation
technologien der » technologien des, technologie der, technologien fur
4 communication » 3 communication, 5.4 communication, de communication
3 developing » 3 development
developing a » developing _
costs 3 » costs _, costs 4, costs a
a areas » 1 areas, 2 areas, 4 areas
a amp » r amp, o amp, _ amp
m amp » r amp, o amp

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 amp) OR (m amp)) 4 communication costs 3 developing a areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien der transformation ((a amp) OR (m amp)) 4 communication costs 3 developing a areas.*.
