technology dlt » technology data, technology debts, technology 21st
l afrique » en afrique
2 risk » 3 risk, 4 risk
a et » a set, a net, a bet

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: "technology dlt transformation _ 2 risk communication ((a et) OR (a best)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology dlt transformation _ 2 risk communication ((a et) OR (a best)) developpement l afrique.*.
