Talvez deva tentar algumas variações de ortografia:
activity changes » activity center (Expandir a busca), connectivity changes (Expandir a busca), salinity changes (Expandir a busca)
changes decrease » changes increase (Expandir a busca), change increase (Expandir a busca), recharge decrease (Expandir a busca)
code activity » core activity (Expandir a busca), care activity (Expandir a busca), bone activity (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 activity changes decrease ) OR ( _ python python python programming ))~.
