water compensation » wages compensation, wage compensation, career compensation
technologies 2 » technologies _, technologies 4
developing em » developing e, developing eq, developing amp
em africa » 1 africa
1.3 4 » 1.3 _, 1.3 a, 1.3 2
1.2 4 » 1.2 _, 1.2 a, 1.2 r

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 2 information content _ water compensation ((1.3 4) OR (1.2 4)) developing em africa.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information content _ water compensation ((1.3 4) OR (1.2 4)) developing em africa.*.
