The regular mode of the 3rd kind (method of periodic heating) is one of the effective ways to measure a complex of thermal characteristics (thermal conductivity, thermal diffusivity and heat capacity) of gases and liquids (see, for example, the works of L.P. Filippov and S.N. Kravchun). Currently, this method has become widely used to study the thermal properties of solids. In our works, schemes of the process of heat transfer in the system of three contacting bodies ? the sample under study and two semi-limited (...

Currently, the population of the Earth, reaching a value of 7.2 billion people (2014), continues to grow rapidly. This leads to an increase in the demand for food, energy, minerals, which in turn enhances the anthropogenic impact on the biosphere, at the same time increases production and consumption waste and worsens the ecological situation. The problems of urbanization should be attributed to the most acute technospheric problems - increasing the role of cities in the development of society, as well as the grow...
