Поэтика народнического травелога конца XIX века (путевые очерки Ф. Д. Нефедова)
No full text462The article deals with the late stage of the Narodnik?s (populist) fiction of early 1890-s in the aspect of deep cognition of Russia, which was important on the turn of the century. The subject matter is the travel essays of the writer-ethnographer F.D. Nefedov, who is forgotten nowadays. The article describes some features of the poetics of the Narodnik?s travelogue (the narrator, the compositional principle of contrast a conflict within a single scene, etc.), the originality of the demonstration of the author?s position and synthetical genre structure. According to the type of the plot construction Nefedov?s travelogue is close to a story. His plot is not only localy attached to a certain scene or a situation, but also contains the idea which is expressed in the attempts of the privileged class characters to get closer to the ordinary people, but their realization remains outside the plot. The poetics of Nefedov?s travel essays reflects both the ideological position of the author an

Investigation of wear of insulation of traction engines of locomotives in operation
No full textThe article analyzes reliability of traction electric motors in operation. It is shown that the greatest number of failure falls on the winding of the armature. Investigation of the causes of increased wear of the armature winding insulation was carried out using the dynamic thermal model of the electric motor. The model is represented by 150 final elements and takes into account the conditions of thermal conductivity between the nodes and heat transfer to the cooling air. Verification of the model was carried out by comparison with the results of thermal tests of electric motors of the series HБ-406 and ЭД-118. The field of temperatures in the traction motor under various loads was investigated. It is shown that in stationary mode the temperature change along the armature winding can reach 60C. Modeling of thermal dynamic processes in the engine during its operation on the locomotive allowed to identify the most stressed nodes. It is shown that the resource of the electric motor is determined by the wear of the insulation of the frontal part of the armature winding on the side of the traction drive of the locomotive
Russia’s Modern Banking Law
No full textIn this study, the author offers a very general review of banking legislation in Russia. The author discusses the main statutory acts which regulate banking activity and the Central Bank of the Russian Federation (Bank of Russia). The author describes the Bank of Russia’s functions. He concludes that, in modern market conditions, it is extremely important to develop civil regulation and reduce administrative regulation; however, he finds that, unfortunately, the Bank of Russia is still subject to administrative management. Considering the nature of the relationships between the Bank of Russia and private credit organizations, the author insists on the need for a partnership, forged on principles of dispositive regulation, between them. More generally, this work considers the problems of domestic financial regulation through the theoretical prism of free banking. Current Russian banking legislation only focuses on the creation of the best mechanism for the organization of credit and financial relationships. The author considers not only the requirements for state financial policy, but also the interests of private credit organizations, which serve as the engine of the financial market and strengthen the banking system as a whole. Until recently, many aspects of the Russian banking system have been a compromise between the old and new conceptions of the economy. For this reason, the upholding of free market ideas is essential in order to develop banking legal theory. The author criticizes the emerging tendency to reduce the role of liberal financial institutions, such as the increasing role of the Bank of Russia as a mega-regulator. Considering this, the author recommends the application of immediate counteractions against the above-described tendency and supports the strengthening of the independence of credit organizations. He emphasizes that this is the only approach to fully develop the existing banking system.In this study, the author offers a very general review of banking legislation in Russia.

Synthesis of Lithium Peroxide from Hydrogen Peroxide and Lithium Hydroxide in Aqueous-Organic Medium: Wasteless Technology
No full textLithium is a rare element, and widely used in manufacturing, electronics, medicine, and etc. One of the important lithium compounds is lithium peroxide. It is a component of regenerating products to protect the human respiratory system from damaging factors of chemical and biological nature. This paper describes the methods of obtaining the lithium peroxide. All industrial techniques for the synthesis of lithium peroxide are presented. A critical assessment of these techniques is given. A new wasteless synthesis technology of lithium peroxide from Hydrogen Peroxide and Lithium Hydroxide in Aqueous-Organic Medium is presented. This technology allows obtaining the pure product containing Li2O2 up to 94 %. The possibility of the solvent regeneration by the anhydrous lithium hydroxide has been shown. The yield of the lithium – 98 % and a significant reduction in solvent consumption per unit of finished product has been obtained

Dynamics of Grain Yields in European Russia in the 19th — Early 20th Centuries: The Extent of Knowledge of the Issue
No full textThis article deals with the problems of research in national science of the dynamics of grain yields in European Russia between the nineteenth and early twentieth centuries.
For the purpose of the article, the author refers to crop statistics. Disputes about their reliability have been going on for about two hundred years, however, no irrefutable evidence of their unreliability has been presented. This is also true about the discussion of the early twenty-first century, where the source was criticised by B. N. Mironov and M. A. Davydov, and their opponents were S. A. Nefedov, A. V. Ostrovsky, and I. A. Kuznetsov.
Interest in the dynamics of productivity emerged in the late nineteenth century. The focus of attention was the question of whether there was an increase in productivity in the period under review or not. At the turn of the twentieth century, A. F. Fortunatov and R. I. Preger maintained that productivity had increased, and I. Kh. Ozerov argued that it had not.
In the 1920s, three views on the character of yield dynamics formed. V. G. Mikhailovsky and M. I. Semenov talked about a growth in yield combined with cyclical and random fluctuations. F. Cherevanin wrote that the yield in European Russia changed exclusively cyclically. V. M. Obukhov and A. L. Weinstein argued that grain yields grew, obscured by random fluctuations, in the absence of a cyclical component.
It was the third point of view that prevailed with B. S. Yastremsky, A. S. Nifontov, A. V. Ostrovsky, V. G. Rastyannikov, and I. V. Deryugina following it. Only N. O. Voskresenskaya questioned the widespread increase in productivity.
However, the previously used research methods (interval enlargement, correlation-regression analysis) are imperfect, and therefore the findings require rechecking using methods that are not in demand by national science for the analysis of crop statistics (hypothesis of the averages, Foster — Stewart method), which will help to better understand the nature grain yield dynamics in European Russia in the nineteenth and early twentieth centuries

A Theory of Demographic Cycles and the Social Evolution of Ancient and Medieval Oriental Societies (translation)
No full textA theory of demographic cycles is developed by the author out of the contributions of many sciences. F. Braudel named these cycles as "secular trends," and R. Cameron used the concept of "logistics cycles." The author constructs a mathematical model of a demographic cycle. With the help of this model the cycle is divided into phases for which the author is able to determine about 40 qualitative attributes of the cycle. These attributes allow a demographic cycle to be identified in the real course of a history even in the absence of quantitative data about a population. With the help of this method 57 demographic cycles are identified in the history of the various countries of the East. In particular, it is shown that the increase of demographic pressure at the end of a cycle results in establishment of étatist monarchy
