Talvez deva tentar algumas variações de ortografia:
disease changes » disease chagas (Expandir a busca), disease challenges (Expandir a busca), disease stages (Expandir a busca)
changes process » change process (Expandir a busca), changes processes (Expandir a busca), exchanges process (Expandir a busca)
decrease spot » decrease sod (Expandir a busca), decrease soon (Expandir a busca), decrease of (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
spot disease » host disease (Expandir a busca), wilt disease (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 spot disease changes process ) OR ( python dados python python programming ))~.
