However local areas may be much higher.

Unfortunately, there are too many scientific articles out there that support such extremes.Umbertohttps://www.blogger.com/profile/05219934919420110457noreply@blogger.comtag:blogger.com,1999:blog-1050248510534718852.post-62476074260650665792012-02-24T16:17:12.834+01:002012-02-24T16:17:12.834+01:00Thanks for this.
