Talvez deva tentar algumas variações de ortografia:
decreased level » decreased levels (Expandir a busca), increased levels (Expandir a busca)
level decrease » leaves decrease (Expandir a busca), level increase (Expandir a busca), levels increase (Expandir a busca)
dose processes » noise processes (Expandir a busca), coke processes (Expandir a busca), use processes (Expandir a busca)
decrease dose » decrease due (Expandir a busca), decrease costs (Expandir a busca), decrease model (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decreased level decrease dose processes ) OR ( python _ python python programming ))~.
