Talvez deva tentar algumas variações de ortografia:
sampling defects » sampling effects (Expandir a busca), sampling devices (Expandir a busca), sampling effect (Expandir a busca)
defects decrease » events decrease (Expandir a busca), elements decrease (Expandir a busca), defects created (Expandir a busca)
decrease using » decrease during (Expandir a busca), decrease owing (Expandir a busca), decreased during (Expandir a busca)
using program » housing program (Expandir a busca), nursing program (Expandir a busca), aging program (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)
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: (( sampling defects decrease using program ) OR ( python code python python programming ))~.
