brenda, this is new territory for me. Could you explain a bit about deep penetration? Which machines achieve it, how that works, and if these machines are as effective for acute infections as the 'shallower' ones...........if you know any of this.
I'm also happy to read books, but it's sure easier if they've been pre-screened. If anybody has specific recommendations, I'll start getting literate.
