Perhaps you should try some spelling variations:
oral communication » personal communication
3 transformation » 1 transformation, 4 transformation, e transformation
transformation 1 » transformation _, transformation a, transformation 3
technologies 3 » technologies _, technologies 4, technologies 2
4 developing » 3 developing
we oral » new oral, who oral, why oral
costs 4 » costs _, costs a, costs 4.2
e real » 1 real, 4 real, 3 real
1 we » 1 wie, _ we, 1 le

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: "technologies 3 transformation 1 we oral communication costs 4 developing ((e real) OR (2 real)).~".
• Adding a wildcard symbol may retrieve word variants: technologies 3 transformation 1 we oral communication costs 4 developing ((e real) OR (2 real)).*.
