Talvez deva tentar algumas variações de ortografia:
decrease survival » decreased survival (Expandir a busca), decreases survival (Expandir a busca), increase survival (Expandir a busca)
survival program » survival progress (Expandir a busca), survival nomogram (Expandir a busca), survival from (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
decrease can » decrease in (Expandir a busca), decrease and (Expandir a busca), decrease at (Expandir a busca)
can decrease » and decrease (Expandir a busca), can increase (Expandir a busca), to decrease (Expandir a busca)
python api » python and (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease can decrease survival program ) OR ( python api python python programming ))~.
