Talvez debería tentar con algunhas variantes ortográficas:
communication mitigation » communication motivation, communication mitigating, communication situation
mitigation safety » navigation safety, fumigation safety, mitigation strategy
dspaces » ddspaces
dddspaces » ddddspaces
space » dspace

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: communication mitigation safety ((dspaces OR dspaces) OR dddspaces) euclidean space~.
• Adding a wildcard symbol may retrieve word variants: communication mitigation safety ((dspaces or dspaces) or dddspaces) euclidean space*.
