Talvez deva tentar algumas variações de ortografia:
decrease separation » decrease cooperation (Expandir a busca), decrease migration (Expandir a busca), microphase separation (Expandir a busca)
separation process » separation processes (Expandir a busca)
code decrease » oxide decrease (Expandir a busca), roads decrease (Expandir a busca), to decrease (Expandir a busca)
python xcode » python code (Expandir a busca), python cuda (Expandir a busca)
xcode java » codes java (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 decrease separation process ) OR ( python xcode java python programming ))~.
