Talvez deva tentar algumas variações de ortografia:
decreased need » decreased level (Expandir a busca), decreased sleep (Expandir a busca), decreased semen (Expandir a busca)
risk processes » risk process (Expandir a busca), work processes (Expandir a busca), k processes (Expandir a busca)
pythons python » python python (Expandir a busca), pitons python (Expandir a busca), piton python (Expandir a busca)
need decrease » speed decrease (Expandir a busca), speed decreases (Expandir a busca), and decrease (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease in (Expandir a busca)
and pythons » and python (Expandir a busca)
python and » python based (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decreased need decrease risk processes ) OR ( python and pythons python programming ))~.
