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)
course python » course action (Expandir a busca), course path (Expandir a busca)
decrease of » decrease in (Expandir a busca)
python base » python based (Expandir a busca), python task (Expandir a busca), python casos (Expandir a busca)
base course » based course (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 base course python programming ))~.
