Talvez deva tentar algumas variações de ortografia:
refractive programs » reactive programs (Expandir a busca), reproductive programs (Expandir a busca), effective program (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 refractive » method effective (Expandir a busca), the refractive (Expandir a busca), to refractive (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease AND decrease decrease processes ) OR ( python _ method refractive programs ))~.
