Talvez deva tentar algumas variações de ortografia:
diffractive phase » diffractive mass (Expandir a busca), diffractive photo (Expandir a busca), diffractive physics (Expandir a busca)
code diffractive » and diffractive (Expandir a busca), of diffractive (Expandir a busca), the diffractive (Expandir a busca)
phase decrease » the decrease (Expandir a busca), phase release (Expandir a busca), rate decrease (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 diffractive phase decrease ) OR ( _ python python python programming ))~.
