Perhaps you should try some spelling variations:
publicaciones peridicas » publicaciones periodicas, publicaciones seriadas, publicacion periodica
peridicas instituto » juridica instituto, juridicos instituto, politicos instituto
instituto biologico » instituto geologico, instituto biblico, instituto tecnologico
de mineria » de materia, la mineria
y mineria » y miseria, la mineria, y miserias

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "publicaciones peridicas instituto biologico ((y mineria) OR (de mineria)) de espana ;~".
• Adding a wildcard symbol may retrieve word variants: publicaciones peridicas instituto biologico ((y mineria) OR (de mineria)) de espana ;*.
