Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
have transformed » has transformed, a transformed, law transformed
schemes versus » schemes vss, schools versus, smes versus
transformed de » transformed _, transformed 1, transformed a
mais transfer » mass transfer, gas transfer, mit transfer
vague de » vagues de, langue de, vue de
vague we » vagues de, value web, vague _
de mais » des mais, die mais, de maio
acao » cacao, macao, cao

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: (( vague de mais transfer schemes versus ) OR ( vague we have transformed de acao ))~.
• Adding a wildcard symbol may retrieve word variants: (( vague de mais transfer schemes versus ) or ( vague we have transformed de acao ))*.
