Talvez deva tentar algumas variações de ortografia:
coder perfusion » modern perfusion (Expandir a busca), under perfusion (Expandir a busca), liver perfusion (Expandir a busca)
ct programming » c programming (Expandir a busca), co programming (Expandir a busca), cost programming (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
perfusion ct » perfusion in (Expandir a busca), perfusion _ (Expandir a busca), perfusion of (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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