Hollow nanoparticles of silicon dioxide (SiO 2) have been obtained using Cu/SiO 2 core-shell nanoparticles as precursors. An original technique based on heating the precursor nanoparticles to T = 400°C followed by a nanochemical reaction of copper oxide separation from hollow silica particles has been proposed and implemented for the first time. The obtained hollow SiO 2 nanoparticles have been studied by transmission electron microscopy. Mechanisms involved in the formation of hollow silica nanoparticles are discussed. © 2012 Pleiades Publishing, Ltd.

Metal-semiconductor composite Ag-Si nanostructures, including Ag/Si core-shell nanoparticles, have been synthesized for the first time by a high-efficiency evaporation/condensation method using relativistic electron beam. In the Ag/Si core-shell nanoparticles, the core is crystalline, while the shell consists of amorphous silicon. It is found that the synthesis of these particles requires taking into account the difference in the saturated vapor pressures of evaporated components. The dependences of the particle size on the electron beam power at the evaporation stage and the pressure of argon at the condensation stage have been studied. It is established that (i) the main process of Ag/Si nanoparticle formation is coagulation and (ii) the Si shell formation decreases the size of particles. © 2012 Pleiades Publishing, Ltd.

We describe the results of a spectral and correlation analysis of changes in the daily dispatches of ambulance teams over 3 years. The results show fluctuations with periods of 7, 41, 50-51, 68-82, 136, 227, and 310-365 days and small-amplitude fluctuations with periods of 11, 13-14, 17-18, 23, 29, 31, 36, and 58 days. Some of these coincide with the predictions of Tibetan medical sources. The periods under observation closely match the changes in the gradient of the Earth's electric field potential. © 2012 Pleiades Publishing, Ltd.

In the nonlinear problems of optimal control, a nonlocal improvement procedure with a linear Skolem's function was constructed for the continuous and discrete systems on the basis of V.F. Krotov's theory of sufficient optimality conditions. Examples, including improvements of the singular and nonsingular Pontryagin extremals, were given. © Pleiades Publishing, Ltd., 2010.

The article presents dialogic attitude towards nature and focuses on the aesthetic form of interaction with environment via folklore and imaginative writing. The article analyzes the development of scientific thought from human ecology to environmental hermeneutics. Hermeneutic methodology is used in the field of "aesthetics of nature", therefore, the author applies hermeneutic categories such as tradition, historically effective consciousness, hermeneutic circle, application to cultural heritage of one of Siberia's natives and proves the advantages, heuristic value of these categories in analyzing dialogue with nature. Aesthetic dialogue with nature is studied on the example of ethnic and ecological traditions of the Buryat nomads, who historically migrated across Central Asia, nowadays live around Lake Baikal. The author argues that revitalizing ethnic and ecological traditions in folklore and contemporary national literature presents a hermeneutic dialogue with nature and considers it a valuable resource for ethical assumptions and ecological education for sustainable development.

A linear correlation between the modulus of elasticity and the inverse square of the thermal expansion coefficient for inorganic glasses has been found. The nature of interrelation between linear and nonlinear properties of solids has been discussed. © 2014 Pleiades Publishing, Ltd.

Alternative principle of the phase diagram (PD) engineering has been offered: 1) a space scheme of 3-phase regions is to be elaborated; 2) contours of the surfaces of unruled nature are to be closed and data of thermodynamic assessment are used on this stage; 3) surfaces should be approximated as the minimal ones (with the minimal area); 4) all geometrical elements are designated, and their 'names' contain the meaning (reason) of these designations; 5) after the computer assembling the PD space model becomes a useful tool to solve different fundamental and applied tasks of materials science. © 2012 IEEE.

In this article we study Boolean functions with two kinds of indeterminacy. We prove criterion of decomposition of this functions including separating decomposition. As a result we have method that allows to obtain representation of an arbitrary function using superposition of functions that have smaller dimentions. © Siberian Federal University.

We construct a special differential-algebraic boundary problem for nonlocal control improvement in systems linear with respect to the control. Based on the improvement boundary problem, we formulate a new necessary optimality condition that strengthens the maximum principle. For controls satisfying the maximum principle, we give examples of strict improvement with the proposed boundary problem. © 2011 Pleiades Publishing, Ltd.

Fine-grained corundum-based ceramics have been obtained by pressing and subsequent sintering a mixture of nanodimensional alumina (Al2O3), magnesia (MgO) and silica (SiO2) powders. The structure and properties of the obtained ceramics have been studied by scanning electron microscopy, scanning probe microscopy, and X-ray diffraction analysis. It is established that the modifying additive of nanodisperse silica (0.05%) produces an almost 40% increase in the microhardness of ceramics. © 2010 Pleiades Publishing, Ltd.
