Perhaps you should try some spelling variations:
transformation based » transformation case, transformation a, transformation als
und transformation » die transformation, der transformation, rural transformation
technologien und » technologie und, technologien des, technologien fur
4 developing » 3 developing
developing 2 » developing _, developing a, developing e
costs 4 » costs _, costs a, costs 4.2
2 areas » 1 areas, 2 areal, 4 areas
dm 4 » hdm 4, am 4, de 4

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 und transformation based ((dm 4) OR (d 4)) communication costs 4 developing 2 areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien und transformation based ((dm 4) OR (d 4)) communication costs 4 developing 2 areas.*.
