Talvez deva tentar algumas variações de ortografia:
function models » functional models (Expandir a busca), functional model (Expandir a busca), duration models (Expandir a busca)
decrease based » decreased base (Expandir a busca), decrease blood (Expandir a busca)
models vpython » modeling vpython (Expandir a busca), modulo python (Expandir a busca)
vpython python » python python (Expandir a busca), pythons python (Expandir a busca), piton python (Expandir a busca)
code decrease » oxide decrease (Expandir a busca), roads decrease (Expandir a busca), to decrease (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code decrease based program ) OR ( function models vpython python programming ))~.
