Talvez debería tentar con algunhas variantes ortográficas:
communication concepts » communication circuits, communication congresses, communication channels
basic dimensions » based dimension, pacific dimensions, design dimensions
regression live » regression line, regression lines, regression link
concepts basic » concepts cases, concepts case

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 concepts basic dimensions ((regression live) OR (regression linear))~.
• Adding a wildcard symbol may retrieve word variants: communication concepts basic dimensions ((regression live) or (regression linear))*.
