Talvez deva tentar algumas variações de ortografia:
vpython programming » python programming (Expandir a busca), method programming (Expandir a busca), creation programming (Expandir a busca)
decrease processes » disease processes (Expandir a busca), defense processes (Expandir a busca), decay processes (Expandir a busca)
decrease decrease » decrease release (Expandir a busca), disease decreases (Expandir a busca), decrease sucrose (Expandir a busca)
oxide decrease » oxide decreases (Expandir a busca), oxide increases (Expandir a busca), oxide release (Expandir a busca)
models vpython » modeling vpython (Expandir a busca), modulo python (Expandir a busca)
python based » action based (Expandir a busca)
based models » based model (Expandir a busca), mixed models (Expandir a busca)
1 oxide » n oxide (Expandir a busca), 1 oxido (Expandir a busca), of oxide (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( 1 oxide decrease decrease processes ) OR ( python based models vpython programming ))~.
