Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
transformed de » transformed _, transformed 1, transformed a
a transformed » _ transformed, _ transformer, a transforming
schemes vss » schemes das, schemes use, schemes versus
langue de » langue du, lange der
vagues do » vagues de, aguas do, vague de
de sacao » de acao, de sac, de sala
do a » do _, do i, dr a
heat » head

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: (( langue de heat transfer schemes vss ) OR ( vagues do a transformed de sacao ))~.
• Adding a wildcard symbol may retrieve word variants: (( langue de heat transfer schemes vss ) or ( vagues do a transformed de sacao ))*.
