Talvez deva tentar algumas variações de ortografia:
disease processes » disease process (Expandir a busca), disease progress (Expandir a busca), these processes (Expandir a busca)
decrease disease » decreases disease (Expandir a busca), increase disease (Expandir a busca), increased disease (Expandir a busca)
decrease faster » decrease after (Expandir a busca), decrease further (Expandir a busca), decreased after (Expandir a busca)
faster decrease » rate decrease (Expandir a busca)
tier python » the python (Expandir a busca), theory python (Expandir a busca), lines python (Expandir a busca)
python two » python to (Expandir a busca), python tools (Expandir a busca), python tutor (Expandir a busca)
two tier » two times (Expandir a busca), two time (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease faster decrease disease processes ) OR ( python two tier python programming ))~.
