Perhaps you should try some spelling variations:
scales communication » scale communication, states communications, called communication
development east » development southeast, development 1
la development » a development, ma development, 2 development
east afrique » east africa, east african, en afrique
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 _ information ((pt 3) OR (pt 1)) scales communication a la development east afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information ((pt 3) OR (pt 1)) scales communication a la development east afrique.*.
