Talvez deva tentar algumas variações de ortografia:
perception programme » prevention programme (Expandir a busca), promotion programme (Expandir a busca), protection programme (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 perception » emotion perception (Expandir a busca), method description (Expandir a busca), food perception (Expandir a busca)
decrease of » decrease in (Expandir a busca)
of decrease » or decrease (Expandir a busca), not decrease (Expandir a busca), to decrease (Expandir a busca)
python i » python in (Expandir a busca), python _ (Expandir a busca), python c (Expandir a busca)
i method » ii method (Expandir a busca), i methods (Expandir a busca), ri method (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease of decrease decrease processes ) OR ( python i method perception programme ))~.
