Talvez deva tentar algumas variações de ortografia:
decrease processes » disease processes (Expandir a busca), defense processes (Expandir a busca), decay processes (Expandir a busca)
decrease decrease » decrease release (Expandir a busca), disease decreases (Expandir a busca), decrease sucrose (Expandir a busca)
rare decrease » rate decrease (Expandir a busca), are decreased (Expandir a busca), ratio decrease (Expandir a busca)
forest rare » forest are (Expandir a busca), forest area (Expandir a busca), forest core (Expandir a busca)
pitons » citons (Expandir a busca), pitoni (Expandir a busca), pitoes (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( forest rare decrease decrease processes ) OR ( python data pitons python programming ))~.
