The disposal and recycling of chlorohydrocarbons waste from organic synthesis which is annually produced at least 1,5 million tons is one of the global problems and is under the great UN's attention. Organochlorine residues are xenobiotics and adversely affect the environment.  Thermodynamic modeling of interactions in the systems ZnO-CHxCly (x + y= 4)-O2 for determination of the theoretical content of chlorohydrocarbons as chlorinating agents for extracting nonferrous metals from very concentrated ore is presented in this article. The studies were conducted using the "Astra" software based on the principle of maximum entropy. Infobase of the "Astra" complex contains information on 5547 compounds, 79 items codified in the National Bureau of Standards and the Joint Institute for High Temperatures, Russian Academy of Sciences.

Is it possible to measure the dispersion of ex ante chances (i.e., chances “before the event”) among people, be it gambling, health, or social opportunities? We explore this question and provide some tools, including a statistical test, to evidence the actual dispersion of ex ante chances in various areas, with a focus on chronic diseases. Using the principle of maximum entropy, we derive the distribution of the risk of becoming ill in the global population as well as in the population of affected people. We find that affected people are either at very low risk, like the overwhelming majority of the population, but still were unlucky to become ill, or are at extremely high risk and were bound to become ill.
