Talvez deva tentar algumas variações de ortografia:
activation changes » activation enhances (Expandir a busca), lactation changes (Expandir a busca), activities changes (Expandir a busca)
clone activation » gene activation (Expandir a busca), cyclase activation (Expandir a busca), hormone activation (Expandir a busca)
changes decrease » changes increase (Expandir a busca), change increase (Expandir a busca), recharge decrease (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code clone » code clones (Expandir a busca), made clone (Expandir a busca), code code (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code clone activation changes decrease ) OR ( _ python python python programming ))~.
