A sua pesquisa - communication conversation based dimensions ((model linear) or (modern life))* - não corresponde a nenhum registo.

Talvez deva tentar algumas variações de ortografia:
communication conversation » communication information, communication cohesion, communication communication
conversation based » conversion based, conversation basic, conversation made
based dimensions » based dimension, basic dimensions, based dimensioning
model linear » models linear

Pode obter mais resultados ajustando a pesquisa.
