Perhaps you should try some spelling variations:
technologies used » technologies based, technology used, technologies _
sich development » sic development, tech development, speech development
used innovation » user innovation, use innovation, based innovation
development l » development li, development 1, development law
l afrique » en afrique
a sich » _ sich, 1 sich, e sich
1 gas » _ gas, 2 gas, a gas
3 gas » _ gas, 2 gas

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 used innovation ((1 gas) OR (3 gas)) mass communication a sich development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies used innovation ((1 gas) OR (3 gas)) mass communication a sich development l afrique.*.
