Talvez deva tentar algumas variações de ortografia:
cases processes » cases processed (Expandir a busca), based processes (Expandir a busca), bases processos (Expandir a busca)
disease cases » disease case (Expandir a busca), disease caused (Expandir a busca), disease carta (Expandir a busca)
decrease std » decrease sod (Expandir a busca), decrease and (Expandir a busca), decrease at (Expandir a busca)
python based » action based (Expandir a busca)
std disease » seed disease (Expandir a busca), and disease (Expandir a busca), old disease (Expandir a busca)
hiv python » in python (Expandir a busca), via python (Expandir a busca), lib python (Expandir a busca)
based hiv » based high (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease std disease cases processes ) OR ( python based hiv python programming ))~.
