There is a considerable debate between research groups applying the two-stage clonal expansion model for lung cancer risk estimation, whether radon exposure affects initiation and transformation or promotion. The aim of the present study is to quantify the effects of radon progeny on these stages with biophysical models. For this purpose, numerical models of mutation induction and clonal growth...

Based on the methods of non-equilibrium thermodynamics, it was found that implementation spontaneous processes with positive entropy production during friction leads to an increase in wear intensity. Non-spontaneous negative lead a decrease The tribological characteristics diamond-like carbon (DLC) different silicon content were studied. intensity practically does not correlate coefficient. It ...
