A sua pesquisa - ((communication cohesion) or (communication control)) mode dispersion euler like - não corresponde a nenhum registo.

Talvez deva tentar algumas variações de ortografia:
communication cohesion » communication collections, communication cost, communication apprehension
communication control » communication concepts, communication culture, communication channel
dispersion euler » dispersion other, dispersion after, dispersion fiber
mode dispersion » wave dispersion, dioxide dispersion, based dispersion
euler like » euler line, heusler like, teller like

Pode obter mais resultados ajustando a pesquisa.
