Talvez debería tentar con algunhas variantes ortográficas:
communication conclusions » communication solutions, communication contributions, communications connections
conclusions methods » conclusion methods, inclusion methods, conclusions authors
methods dimension » methods diffusion, ethics dimension, metholodgy dimension
phase spaces » phase space, shape spaces, state spaces
safe spaces » state spaces, shape spaces, scale spaces
use spaces » tuple spaces, gauge spaces, whose spaces

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 conclusions methods dimension ((((use spaces) OR (safe spaces))) OR (phase spaces))~.
• Adding a wildcard symbol may retrieve word variants: communication conclusions methods dimension ((((use spaces) or (safe spaces))) or (phase spaces))*.
