Talvez deva tentar algumas variações de ortografia:
conceptions presented » concepcoes presentes (Expandir a busca), conceitos presentes (Expandir a busca)
presented decrease » prevent decrease (Expandir a busca), pressure decrease (Expandir a busca), related decrease (Expandir a busca)
code conceptions » model conceptions (Expandir a busca), some conceptions (Expandir a busca), role conceptions (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 conceptions presented decrease ) OR ( _ python python python programming ))~.
