Perhaps you should try some spelling variations:
transfer scheme » transfer systems
a transformed » _ transformed, _ transformer, a transforming
scheme prior » schemes prior, scheme from, schemes pro
agua et » agua e
1 macao » _ macao, 2.1 macao
1 macro » _ macro, a macro, 2 macro
agua 2 » agua e, agua _, agua y
2 heat » _ heat, a heat, 1 heat
et a » et al, et la, e a

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: (( agua 2 heat transfer scheme prior ) OR ( agua et a transformed ((1 macao) OR (1 macro)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua 2 heat transfer scheme prior ) or ( agua et a transformed ((1 macao) OR (1 macro)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua 2 heat transfer scheme prior ) or ( agua et a transformed ((1 macao) OR (1 macro)) ))*.
