Return to Sender  and if that don't work try this Return to Sender

These drawings you can pull up.  I've converted them to editable (that's e.d.i.t._a.b.l.e, you are able to edit as in editing a student's English paper, paper, not eatable or readable.  The full 15 pages constitute the tutorial section of the original manuscript.  Because it is really late again my time (USA central daylight time) I have not posted all 15. And this is just initial "scratch pad" stuff.  Wait until links and supporting color photos and images and animations are included. I intend to provide email where those who want to can "have at it" and be creative in their own way. Do it your way.  What ever you come up with - be sure to give credit to the original creators, the doctors and publisher.

One important thing you need to do to follow along. The various browsers will open some things up and some things not. PDF files are more or less universal in the computer world.  I open up pdf using some elegant commercial software because you can do a lot with pdf.  But for the general audience, you need to open these files with sofware that works on most all pdf's. I recommend you set the "Open WITH" and go on down and select Open always with xxxx.  I use Microsoft Edge because it also has a really nice OCR feature where you can scan documents into pdf or jpg and then convert jpg into pdf and with Microsoft Edge you can copy on the internet the text which you have uploaded to MS Edge and then download that text to MS Word. Really nice feature.  So set your "OPEN WITH" to the browser you like most and then these files will open up.

I have tested every one of the above pages.  I open up the website, the-cardiac-engine.net and click on say, page 8. Then with the OPEN UP WITH set to always open a pdf in MS Edge each drawing comes up correctly. Now also remember that these drawing, though they be pdf, still are large.  And older computer may have to rely on the hard drive or usb drive, etc to do "paging" where the operating system uses your disk drive for extra memory.
