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)
retention program » prevention program (Expandir a busca), attention program (Expandir a busca), detection program (Expandir a busca)
method retention » metal retention (Expandir a busca), method selection (Expandir a busca), metals retention (Expandir a busca)
python based » action based (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease OR decrease decrease processes ) OR ( python based method retention program ))~.
