Talvez deva tentar algumas variações de ortografia:
cross processes » crisis processes (Expandir a busca), loss processes (Expandir a busca), class processes (Expandir a busca)
decrease spot » decrease sod (Expandir a busca), decrease soon (Expandir a busca), decrease of (Expandir a busca)
disease cross » disease case (Expandir a busca), disease copd (Expandir a busca)
spot disease » host disease (Expandir a busca), wilt disease (Expandir a busca)
python redes » python regius (Expandir a busca), python code (Expandir a busca)
redes pitons » redes pon (Expandir a busca), redes fito (Expandir a busca), redes ptn (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease spot disease cross processes ) OR ( python redes pitons python programming ))~.
