Talvez deva tentar algumas variações de ortografia:
coder perfusion » modern perfusion (Expandir a busca), under perfusion (Expandir a busca), liver perfusion (Expandir a busca)
perfusion in » reperfusion in (Expandir a busca)
in objective » an objective (Expandir a busca), on objective (Expandir a busca), and objective (Expandir a busca)
using coping » using coding (Expandir a busca), using coupling (Expandir a busca), nursing coping (Expandir a busca)
coping and » coping in (Expandir a busca)
and python » in python (Expandir a busca), on python (Expandir a busca), api python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder perfusion in objective programming ) OR ( using coping and python programming ))~.
