Perhaps you should try some spelling variations:
del presente » y presente
presente vol » presente por, presente y, presente en
presente mad » presente a, presente la, presente y
en sciences » les sciences, en pacientes, open science
every » very, overy, eveny, edery
hors » horas, hours, hora
ever » over, even, eder

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: "(((( del presente vol every ) OR ( en sciences hors ever ))) OR ( del presente mad ver ))~".
• Adding a wildcard symbol may retrieve word variants: (((( del presente vol every ) OR ( en sciences hors ever ))) OR ( del presente mad ver ))*.
