Talvez deva tentar algumas variações de ortografia:
sampling areas » sampling area (Expandir a busca), sampling bias (Expandir a busca), sampling grids (Expandir a busca)
time sampling » the sampling (Expandir a busca), active sampling (Expandir a busca), tissue sampling (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)
areas work » areas wood (Expandir a busca), cras work (Expandir a busca), areas network (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( time sampling areas work program ) OR ( python code python python programming ))~.
