Talvez deva tentar algumas variações de ortografia:
sampling density » sampling intensity (Expandir a busca), sampling design (Expandir a busca), stocking density (Expandir a busca)
density decrease » density increase (Expandir a busca), obesity decreases (Expandir a busca), density areas (Expandir a busca)
decrease based » decreased base (Expandir a busca), decrease blood (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( sampling density decrease based program ) OR ( python code python python programming ))~.
