Nonmatrix varieties of nonassociative algebras
A variety of associative algebras is called nonmatrix if it does not contain
the algebra of 2 x 2 matrices over the given field. Nonmatrix varieties were
introduced and studied by V.N.Latyshev in relation with the Specht problem.
Some characterizations of nonmatrix varieties were obtained in the paper [10].
In the given paper the notion of nonmatrix variety is extended for
nonassociative algebras, and the characterization from [10] is generalized for
alternative, Jordan, and some other varieties of algebras
About the need for ideology rehabilitation
The article presents a critical analysis of the orientation toward deideologization and justifies the need for the development of the national Russian ideology, the need for a large-scale work on the consolidation of the modern Russian mass political consciousness on the basis of the proper civilizational identityΠΡΠΈΡΠΈΠΊΡΠ΅ΡΡΡ ΡΡΡΠ°Π½ΠΎΠ²ΠΊΠ° Π½Π° Π΄Π΅ΠΈΠ΄Π΅ΠΎΠ»ΠΎΠ³ΠΈΠ·Π°ΡΠΈΡ ΠΈ ΠΎΠ±ΠΎΡΠ½ΠΎΠ²ΡΠ²Π°Π΅ΡΡΡ Π½Π΅ΠΎΠ±Ρ

How Democracy could foster Economic Growth: The Last 200 Years
In this paper we explore current understandings of the influence of political rights, among historical legacies, on economic development. We construct variables for selected political regimes for 1811-2010. We find significant association between individual rights and economic growth. We argue that current understanding of political regimes supportive of growth (Acemoglu, etc), should parse the concept of property rights to include the protection of the individual in their focus on private property rights protection, alone, respected in various forms of government, are insufficient; what matters is the security of individuals from arbitrary arrest, regardless of βtype of regimeβ. Discretionary rights of rulers or democratic governments to arrest citizens undermines the protection of private property rights and other attributes classically given to democratic foundations of economic growth, for example, free press, freedom of the exercise of religious belief. We suggest, as a research agenda, that the power of the politically competitive system therefore comes from weakening discretionary authority over law enforcemen
Control of the magnitude and spatial distribution of interference energy flows in near fields of systems of identical radiators
The problem of active control for both the magnitude and spatial distribution of individual components of the interference component of the Poynting vector within the near zone of a system of radiators is studied. The characteristic size of this zone is on the order of the wavelength and is characterized by the presence of evanescent (nonpropagating) fields, which are formed due to the interference interaction of radiators. Using multipole expansions for fields and special summation formulas for such expansions allows one to obtain concise expressions convenient in carrying out numerical calculations. The results of calculations confirm the feasibility of the above-mentioned control in principle in solving problems of medium and object sensing
The role played by evanescent fields in the process of formation of radiation of combined radiating systems
The problem of active controlling of the structure of fields of combined radiating systems within their near zone is studied. The characteristic size of this zone is on the order of the wavelength and is characterized by the presence of evanescent (nonpropagating) fields, which are formed, among other things, due to the interference interaction of radiators of the system. Using multipole expansions for fields and special summation formulas for such expansions allows one to obtain concise expressions convenient in carrying out numerical calculations. The results of calculations confirm that the evanescent fieldsβ structure plays a significant part in the process of the formation of the radiation field
The Tools, Technology and Mathematical Model of Impactive Superficial Plastic Deformation of Metals
The paper shows scientific substantiation and practical confirmation of possibility, application expediency and efficiency of the ultrasonic superficial plastic deformation in zones of welded connections after performance of welding works. For this purpose, a mathematical model to the process of superficial plastic deformation is represented, as the hypercycle of loading consisting of elementary cycles β impacts, we described the standard measurement devices. The technology is intended to use the manufacturing and repair of any metal walls in places of dimensional and structural nonuniformity, such as mechanical defects or a local thinning of a surface owing to corrosion, and the microcracks. The microcracks is influenced by the external forces and become zones of concentration of mechanical tension. Hardening in such places of the pipes walls and tanks working under pressure is effective for pipelines of an oil and gas, water supply systems, and also for caissons and tanks of other appointment. The scopes of technology include the repair of river and sea vessels, objects of oil production. The technology can be applied to improvement of operational characteristics of mechanical engineering and transport details, objects of energetic and construction: surfaces of a rolling motion and sliding of machines and devices, wheels of a rolling stock of railway transport, a metalwork of support of power lines, platforms and bridges for increases in resistance of fatigue at cyclic loadings, wear resistance and corrosion
