Talvez debería tentar con algunhas variantes ortográficas:
communication functions » communicative functions, communication foundations, communication foundation
functions centered » function centered, functions altered, functions central
process elasticity » price elasticity, protein elasticity, stress elasticity
precision basic » decision basic, precision elastic, precision mass

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 functions centered ((precision basic) OR (process elasticity)) shear~.
• Adding a wildcard symbol may retrieve word variants: communication functions centered ((precision basic) or (process elasticity)) shear*.
