Talvez deva tentar algumas variações de ortografia:
decreases processes » decrease processes (Expandir a busca)
disease decreases » disease increased (Expandir a busca), disease cases (Expandir a busca), disease disease (Expandir a busca)
python based » action based (Expandir a busca)
decrease of » decrease in (Expandir a busca)
pso python » msn python (Expandir a busca), piton python (Expandir a busca)
based pso » based epso (Expandir a busca), based pcr (Expandir a busca), based pay (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease of disease decreases processes ) OR ( python based pso python programming ))~.
