transform cities » transforming cities, transform cote, transform crisis
der transform » we transform, der transfer, der transfers
cities across » societies across, cities actions, cities address
luis a » luis f, luis c
bis » bias

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: (( bis (ende OR ended) der transform cities across ) OR ( luis a student transfer _ macau ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( bis (ende OR ended) der transform cities across ) or ( luis a student transfer _ macau ))~".
• Adding a wildcard symbol may retrieve word variants: (( bis (ende OR ended) der transform cities across ) or ( luis a student transfer _ macau ))*.
