Talvez deva tentar algumas variações de ortografia:
emissions factor » emission factor (Expandir a busca), emission factors (Expandir a busca), emissions from (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
case program » care program (Expandir a busca), casa program (Expandir a busca), lease program (Expandir a busca)
factor case » factors case (Expandir a busca), factory case (Expandir a busca), factor casa (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( emissions factor case program programa ) OR ( python code python python programming ))~.
