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
david openg » david owens, david heng, david chieng
david zhang » david chang, david chan, david kahane
machin » machine, machines

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 ((david openg) OR (((david zhang) OR (david machin))))~.
• Adding a wildcard symbol may retrieve word variants: information propagation case decision ((david openg) or (((david zhang) or (david machin))))*.
