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)
learning program » learning programme (Expandir a busca), learning problems (Expandir a busca), learning process (Expandir a busca)
python learning » action learning (Expandir a busca), motion learning (Expandir a busca), emotion learning (Expandir a busca)
decrease std » decrease sod (Expandir a busca), decrease and (Expandir a busca), decrease at (Expandir a busca)
std decrease » to decrease (Expandir a busca), and decrease (Expandir a busca), spp decrease (Expandir a busca)
python dados » python data (Expandir a busca), python redes (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease std decrease disease processes ) OR ( python dados python learning program ))~.
