Talvez deva tentar algumas variações de ortografia:
precoding ratio » precedent ratio (Expandir a busca)
ratio decrease » to decrease (Expandir a busca), rats decreases (Expandir a busca)
std programado » estudo programado (Expandir a busca), _ programado (Expandir a busca), nao programado (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
decrease std » decrease sod (Expandir a busca), decrease and (Expandir a busca), decrease at (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: (( precoding ratio decrease std programado ) OR ( python code python python programming ))~.
