Talvez debería tentar con algunhas variantes ortográficas:
communication concepts » communication circuits, communication congresses, communication channels
sources dimensions » resource dimensions, series dimensions, course dimensions
concepts sources » concepts series
large spaces » larger spaces, large space, gauge spaces
safe spaces » state spaces, shape spaces, scale spaces
spaces » dspaces
space » dspace

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication concepts sources dimensions ((large spaces) or (((safe spaces) or (scale space))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication concepts sources dimensions ((large spaces) OR (((safe spaces) OR (scale space)))).
• Adding a wildcard symbol may retrieve word variants: communication concepts sources dimensions ((large spaces) or (((safe spaces) or (scale space))))*.
