Talvez deva tentar algumas variações de ortografia:
amputations using » amputation using (Expandir a busca), computations using (Expandir a busca), imputation using (Expandir a busca)
of amputations » of amputation (Expandir a busca), of imputation (Expandir a busca), of computation (Expandir a busca)
coding pitons » loading pistons (Expandir a busca)
using coding » using coping (Expandir a busca), using coating (Expandir a busca), using cooking (Expandir a busca)
pid program » aid program (Expandir a busca), phd program (Expandir a busca), pibid program (Expandir a busca)
using pid » using pig (Expandir a busca), using rapid (Expandir a busca), using lipid (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( of amputations using pid program ) OR ( using coding pitons python programming ))*.
