An extensive thermodynamic study has been carried out on aqueous solutions obtained through successive dilutions and succussions of 1% in weight of some solutes up to extremely diluted solutions, (less than 1x10-5 mol kg-1) obtained via several 1/100 successive dilution processes.

A rather clueless answer, if you will excuse me. Moopet asked, "what is 50M of water?", and you answer something about 3C of acids and bases. What has that to do with the question?
However, let's nevertheless look at what you write:
Quote:
The interaction of acids or bases with the extremely diluted solutions has been studied calorimetrically at 25°C.
Measurements have been performed of the heats of mixing of acid or basic solutions, having different concentrations, with bidistilled water or with the extremely diluted solutions.
Despite the extreme dilution of the solutions, an exothermic heat of mixing in excess has been found, in about the 92% of the cases, with respect to the corresponding heat of mixing with the untreated solvent.

The article you refer to seems to be here:

Unfortunately, I cannot access it, as access is not free.
However, we can see from your quote that these solutions are "less than 1x10-5 mol kg-1", which would correspond to 3C (that is 1X10-6). We also see that they could only detect anything in 92% of the cases. Since such a reaction is either there or not, we must conclude that the mentioned dilution is close to the noise-floor for the measurement method they use (otherwise they would see 100%).
So, bases and acids react to each other, even when diluted. What else is new?

Here [it is shown] that successive dilutions and succussions may alter permanently the physical-chemical properties of the solvent water.

No it is not shown. It is shown that basic chemistry works in dilution. I could have told you that.
