Perhaps you should try some spelling variations:
technologies von » technologies co, technologies box, technologies can
communication vs » communication v, communication via, communication _
von information » von informationen, can information
development do » development doi, development d, development ds
do african » two african, _ african, 1 african
vs human » 1 human, 10 human
pt 3 » pt 2
pt 1 » pt 2

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: "technologies von information ((pt 3) OR (pt 1)) _ communication vs human development do african.~".
• Adding a wildcard symbol may retrieve word variants: technologies von information ((pt 3) OR (pt 1)) _ communication vs human development do african.*.
