Perhaps you should try some spelling variations:
transfer systems » transport systems, transit systems
transformed de » transformed _, transformed 1, transformed a
a transformed » _ transformed, _ transformer, a transforming
des transfer » des transfers, den transfer, der transfer
systems risk » systemic risk, systemic risks
de macau » de marcas, _ macau, de masa
e des » e der, a des, e das
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 e des transfer systems risk ) OR ( agua et a transformed de macau ))~.
• Adding a wildcard symbol may retrieve word variants: (( agua e des transfer systems risk ) or ( agua et a transformed de macau ))*.
