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)
rat decrease » rate decrease (Expandir a busca), rats decreases (Expandir a busca), ratio decrease (Expandir a busca)
python based » action based (Expandir a busca)
in python » _ python (Expandir a busca)
cost rat » cost at (Expandir a busca), cost raw (Expandir a busca), cost ratio (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( cost rat decrease decrease processes ) OR ( python based in python programming ))~.
