Question

I just need somebody to explain in plain english what "Immune Modulation" is. Google doesn't help at all, it just directs me to bunch of science research papers!

Answer 1

Check this site. Although it's trying to sell an immune modulator, it seems to offer a brief explanation about how it works.

Answer 3

First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.

Second, since this is not my area of expertise, I searched Google under the key words "<I>Mesopotamia irrigation</I>" to get these possible sources:

http://www.learner.org/interactives/collapse/mesopotamia.html
http://www.geology.ucdavis.edu/~cowen/~GEL115/115CH17oldirrigation.html
http://www.waterencyclopedia.com/Hy-La/Irrigation-Systems-Ancient.html
http://i-cias.com/e.o/mesopotamia.htm

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
