The prognosis process is differentiated for different mineralization types and for different rank objects of prognosis. The general structure of prognosis consists of a consecutive chain of the following elements: the object of prognosis ! systematization (classification) of ore objects ! ! creation of geological search models of the prognosis objects ! elucidation of forecast-search criteria ! working out the prognosis rocedures (the methods of investigation). The prognosis of the mineralization is conducted on all stages of geological and prospecting works and is subdivided into regional, middle-scale, large-scale, and local prognoses. The hierarchical rank of an object of the prognosis is changed depending on the stages of geological and prospecting works. It is necessary to create independent geological and genetic models for each object of the prognosis.

The theoretical strength of diamond-like nanoparticles under uniaxial stretching and compression is calculated by the method of pseudopotential. The surface energy of a nanoparticle is defined through the energy of interaction of atomic planes. The functional dependence of the strength on the size, depression, and form of a nanoparticle (nanoplate, nanobar) is obtained. The minimum distance from the external surface of a nanobar, where the theoretical strength coincides with its value for massive samples, as well as the minimum area of the nanobar base when the theoretical strength does not depend on the base form, is evaluated.

The experimental data on the heat transfer on a flat plate after the double array of surface indentations are given. The transition to the turbulent flow after the indentations occurs according to the “bypass” mechanism. It is shown that the shape, depth, and span-wise pitch do not influence the heat transfer intensity after the double array of indentations.

The theorem about equivalence in Lyapunov’s sense of two systems of differential equations of the second order which is an analog of the well-known theorem of M. P. Erugin about the equivalence of systems of differential equations of the first order is proved. Using this theorem, several statements about structural transformations of systems of differential equations of the second order which facilitate the research of stability of the trivial solution are obtained.
