Talvez deva tentar algumas variações de ortografia:
effective decrease » effective disease (Expandir a busca), effective defenses (Expandir a busca)
hiv programming » in programming (Expandir a busca), tv programming (Expandir a busca), aid programming (Expandir a busca)
but effective » but ineffective (Expandir a busca), both effective (Expandir a busca), be effective (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
decrease hiv » decreases hip (Expandir a busca), decrease in (Expandir a busca), decrease il (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( but effective decrease hiv programming ) OR ( python code python python programming ))~.
