Talvez deva tentar algumas variações de ortografia:
decrease initiation » decreased inhibition (Expandir a busca), decrease migration (Expandir a busca), decrease nitrification (Expandir a busca)
initiation program » integration program (Expandir a busca), privatization program (Expandir a busca), immunization program (Expandir a busca)
vpython collisions » vpython colisoes (Expandir a busca), proton collisions (Expandir a busca), photon collisions (Expandir a busca)
collisions python » collisions within (Expandir a busca), collisions with (Expandir a busca), collisions on (Expandir a busca)
code decrease » oxide decrease (Expandir a busca), roads decrease (Expandir a busca), to decrease (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (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 initiation program ) OR ( vpython collisions python python programming ))~.
