Historical and statistical data on the development of the domestic alcoholic beverages industry
The method of historical and statistical data analysis makes it possible to identify development and characteristic patterns, both temporary and permanent, production criteria for various branches of the food industry. The application of this method made it possible to trace formation of the alcohol industry inRussiaand identify critical historical events that influenced its development. The article presents and analyzes statistical data on the production of the main types of alcoholic beverages industry since 1913
Dynamic and thermodynamic properties of the generalised diamond chain model for azurite
The natural mineral azurite Cu3(CO3)2(OH)2 is an interesting spin-1/2 quantum
antiferromagnet. Recently, a generalised diamond chain model has been
established as a good description of the magnetic properties of azurite with
parameters placing it in a highly frustrated parameter regime. Here we explore
further properties of this model for azurite. First, we determine the inelastic
neutron scattering spectrum in the absence of a magnetic field and find good
agreement with experiments, thus lending further support to the model.
Furthermore, we present numerical data for the magnetocaloric effect and
predict that strong cooling should be observed during adiabatic
(de)magnetisation of azurite in magnetic fields slightly above 30T. Finally,
the presence of a dominant dimer interaction in azurite suggests the use of
effective Hamiltonians for an effective low-energy description and we propose
that such an approach may be useful to fully account for the three-dimensional
coupling geometry.Comment: 19 pages, 6 figures; to appear in: J. Phys.: Condens. Matter (special

Providing the countryβs population with quality food products in a demanded range and quantity is an important national economic task. A priori in the implementation of appropriate social and economic programs, an important place is taken by products of the dairy industry. Taking into account the geographical features and climatic conditions of Russia, strategic considerations, the existing fragmentation of the consumer market and economic factors, special importance is acquired by researches, aimed at improving traditional and developing new technologies for canned milk products, asΒ high-nutritional products with a pronounced priority of enhanced storage stability. The system of ensuring the stabilization of canned milk in storage is represented by two main blocks: technologically formed potential and post-technological requirements for its maintenance. The first forms the basic properties of the product and stabilizes them. The second one is to ensure the conditions under which the risks of initiation and/or intensity of the abiogenic and biogenic nature degradation reactions are minimized. To assess the canned milk quality and safety proposed and standardized a number of relevant indicators. However, taking into account the technology development, the expansion of the raw ingredients range, the requirements for the extension of shelf life and much more, the scope of the evaluation criteria for quality and safety indicators is constantly expanding, new methods of a priori and a posteriori analysis are being created, which is fixed in normative and technical documents, that are integrally reflected the level of modern technology. An analysis of the world tendencies in the development of canning, shows, that the reserves of improving the traditional technologies of dairy canned food, increasing their quality, are far from exhausted. Significant potential lies in the research of thermodynamic characteristics, functional and technological indicators of dairy products and further implementation of the obtained data, as system criteria of the technological operations rationality definition, the validity of production schemes, and the evaluation of product quality. The data, obtained over the last decades on the indicator of Β«water activityΒ», inhibition of the degradation of micro and macro components, Β«barrierΒ» conservation technologies and many other directions in various food systems can suggest, that it is possible to mediate most of the methodological approaches applied to canned milk technologies, to predict strategic, economic and social significance of such developments.Β ΠΠ±Π΅ΡΠΏΠ΅ΡΠ΅Π½ΠΈΠ΅ Π½Π°ΡΠ΅Π»Π΅Π½ΠΈΡ ΡΡΡΠ°Π½Ρ ΠΊΠ°ΡΠ΅ΡΡΠ²Π΅Π½Π½ΡΠΌΠΈ ΠΏΡΠΎΠ΄ΡΠΊΡΠ°ΠΌΠΈ ΠΏΠΈΡΠ°Π½ΠΈΡ Π² Π²ΠΎΡΡΡΠ΅Π±ΠΎΠ²Π°Π½Π½ΠΎΠΌ Π°ΡΡΠΎΡΡΠΈΠΌΠ΅Π½ΡΠ΅ ΠΈ ΠΊΠΎΠ»ΠΈΡΠ΅ΡΡΠ²Π΅ ΡΠ²Π»ΡΠ΅ΡΡΡ Π²Π°ΠΆΠ½ΠΎΠΉ Π½Π°ΡΠΎΠ΄Π½ΠΎ-Ρ

Due to existing extensions of the Greens function notion to nonlinear systems, the approach developed here is valid for systems with both linear and nonlinear dynamics. The book offers a number of particular examples, covering specific issues that make the controllability analysis sophisticated, such as coordinate dependent characteristics, point sources, unbounded domains, higher dimensions, and specific nonlinearities. It also offers extensive numerical analysis, which reveals both advantages and drawbacks of the approach. As such, the book will be of interest to researchers interested in the theory and practice of control, as well as PhD and Masters students
Topology optimization for elastic base under rectangular plate subjected to moving load
Distribution optimization of elastic material under elastic isotropic rectangular thin plate subjected to concentrated moving load is investigated in the present paper. The aim of optimization is to damp its vibrations in finite (fixed) time. Accepting Kirchhoff hypothesis with respect to the plate and Winkler hypothesis with respect to the base, the mathematical model of the problem is constructed as twoβdimensional bilinear equation, i.e. linear in state and control function. The maximal quantity of the base material is taken as optimality criterion to be minimized. The Fourier distributional transform and the BubnovβGalerkin procedures are used to reduce the problem to integral equality type constraints. The explicit solution in terms of twoβdimensional Heavisideβs function is obtained, describing piecewiseβcontinuous distribution of the material. The determination of the switching points is reduced to a problem of nonlinear programming. Data from numerical analysis are presented
On adhesive binding optimization of elastic homogeneous rod to a fixed rigid base as a control problem by coefficient
The problem of finite, partially glued to a fixed rigid base rod longitudinal vibrations damping by optimizing adhesive structural topology is investigated. Vibrations of the rod are caused by external load, concentrated on free end of the rod, the other end of which is elastically clamped. The problem is mathematically formulated as a boundary-value problem for onedimensional wave equation with attenuation and variable controlled coefficient. The intensity of adhesion distribution function is taken as optimality criterion to be minimized. Structure of adhesion layer, optimal in that sense, is obtained as a piecewise-constant function. Using Fourier real generalized integral transform, the problem of unknown function determination is reduced to determination of certain switching points from a system of nonlinear, in general, complex equations. Some particular cases are considered
