Talvez deva tentar algumas variações de ortografia:
computations using » populations using (Expandir a busca), computations in (Expandir a busca), communications using (Expandir a busca)
working position » working condition (Expandir a busca), marking positions (Expandir a busca), sowing position (Expandir a busca)
position python » position method (Expandir a busca), piton python (Expandir a busca), position methods (Expandir a busca)
using working » nursing working (Expandir a busca), during working (Expandir a busca), using docking (Expandir a busca)
case program » care program (Expandir a busca), casa program (Expandir a busca), lease program (Expandir a busca)
using case » using cad (Expandir a busca), using charge (Expandir a busca), using castor (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( AND computations using case program ) OR ( using working position python programming ))*.
