Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
transformed de » transformed _, transformed 1, transformed a
mais transfer » mass transfer, gas transfer, mit transfer
a transformed » _ transformed, _ transformer, a transforming
schemes vss » schemes das, schemes use, schemes versus
vague we » vague de, vagues de, value web
we a » web a, owe a, we _
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: (( ((lange der) OR (lange weg)) mais transfer schemes vss ) OR ( vague we a transformed de acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((lange der) OR (lange weg)) mais transfer schemes vss ) or ( vague we a transformed de acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((lange der) OR (lange weg)) mais transfer schemes vss ) or ( vague we a transformed de acao ))*.
