Talvez deva tentar algumas variações de ortografia:
sampling effect » sampling effort (Expandir a busca), sampling efforts (Expandir a busca), coupling effect (Expandir a busca)
effect python » effect method (Expandir a busca), effect author (Expandir a busca)
code decrease » oxide decrease (Expandir a busca), roads decrease (Expandir a busca), to decrease (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
on python » in python (Expandir a busca), of python (Expandir a busca), _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( sampling effect python code decrease ) OR ( on python python python programming ))~.
