Talvez debería tentar con algunhas variantes ortográficas:
information propagation » information presentation, information organization
propagation case » propagation a, micropropagation case, propagation _
case decision » cases decision, case decisions, care decision
from driver » from dried, from liver, from rivers
from river » from liver, from rice

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: information propagation case decision ((from driver) OR (from river))~.
• Adding a wildcard symbol may retrieve word variants: information propagation case decision ((from driver) or (from river))*.
