Talvez deva tentar algumas variações de ortografia:
period programming » grid programming (Expandir a busca), method programming (Expandir a busca), end programming (Expandir a busca)
disease processes » disease process (Expandir a busca), disease progress (Expandir a busca), these processes (Expandir a busca)
decrease ratio » decreased ratio (Expandir a busca), decrease at (Expandir a busca), decreased rate (Expandir a busca)
ratio diseases » to diseases (Expandir a busca), cacao diseases (Expandir a busca), two diseases (Expandir a busca)
coding generic » coding genetic (Expandir a busca), modeling generic (Expandir a busca), codigo generico (Expandir a busca)
generic period » gene period (Expandir a busca), generic error (Expandir a busca), endemic period (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease ratio diseases disease processes ) OR ( python coding generic period programming ))~.
