technologien ad » technologien am, technologien und, technologien als
ad information » d information, nd information, od information
urban africa » urban area

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "technologien ad information ((i 2) OR (iv 2)) parte communication costs _ developing urban africa.~".
• Adding a wildcard symbol may retrieve word variants: technologien ad information ((i 2) OR (iv 2)) parte communication costs _ developing urban africa.*.
