Talvez deva tentar algumas variações de ortografia:
variation programmes » vaccination programmes (Expandir a busca), vaccination programme (Expandir a busca), reparation programmes (Expandir a busca)
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)
method variation » method variations (Expandir a busca), method variational (Expandir a busca), method validation (Expandir a busca)
python based » action based (Expandir a busca)
decrease at » decrease akt (Expandir a busca), decrease and (Expandir a busca), decrease in (Expandir a busca)
at decrease » rate decrease (Expandir a busca), that decrease (Expandir a busca), and decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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