«Theoretical calculation of the dependence of ultimate strength of metals on their physical properties based on the “unpacking” concept of substance»
A theoretical estimate of the dependence of ultimate strength on the physical properties of a solid substance—such as density, molecular weight, melting point, and enthalpy of fusion—has been obtained. This dependence explains how these properties influence the material’s strength based on the “unpacking” concept of substance matter. The physical limits of applicability for the concept of “force” in Newtonian mechanics, and its distinction from the “unpacking” concept, are substantiated. This dependence, while similar in form to the Clapeyron-Mendeleev equation for an ideal gas, has a different physical interpretation when applied to the ultimate strength of a solid. The calculated dependence was compared with tabulated data on the ultimate strength of 15 industrial metals. This model allows for the explanation and prediction of ultimate strength values for metals in the periodic table.

«The analysis of problems and solutions in the joint assembly of carboniferous and Devonian flows for the oil fields of Samara Region»
The paper deals with the use of reagents for the possibility of joint acquisition and preparation of oil and coal-bearing Devonian streams. The analysis of these flows of formed emulsions has been made and chemicals, allowing to destroy the emulsion or prevent its formation have been defined.
