    the last 5 pulled news from disim site and the news stored into the db.
    This decision was made to avoid repeated news, in fact, if some news(from first to fifth)
    is deleted the sixth(that now has become the fifth) news will be sent again even if it is
    already been sent in the past because it will appear in the pulled news and it
    is no more present into the database at the moment of the comparison.
