A sua pesquisa - communication cohesion ((book extraction) OR (bulk extraction)) recursion removal - não corresponde a nenhum registo.

Talvez deva tentar algumas variações de ortografia:
communication cohesion » communication collections, communication control, communication cost
recursion removal » occlusion removal, region removal, turion removal
book extraction » bark extraction, book destruction, disk extraction
bulk extraction » fluid extraction, field extraction
