Restraints on competition in the Russian air passenger market

This article discusses the results of a continuous study of Russian domestic air carriers conducted in 2006–2016 and analyzes the main barriers to entry into the passenger air travel market and their impact on competition in this field. There are significant structural barriers that prevent companies from entering this market. This situation challenges the existing concept and the idea of the domestic air transportation market as a quasi-competitive one. To describe the structure of the Russian passenger air transport market, we introduce the notion of “discrete competition,” reflecting shifted density of market concentration towards small regional airlines. The latter are usually united by ownership mechanisms or affiliation with an airport. They possess considerable market power, but at the same time have an insignificant market share in the overall Russian passenger air market. Administrative barriers also play a crucial role in restraining competition. Furthermore, current institutional conditions are favourable for vertical ‘airport — airline’ integration which results in a fundamental transformation, as described by Williamson, and can be detrimental to competition. As our research findings have shown, there is a trade-off between existing vertically integrated structures in the air passenger market and public welfare

Automation of Educational Institution Documentation

The article addresses issues related to the implementation of the competence approach in order to make the teaching process of an educational institution more efficient, analyzes the reasons for diminished efficiency of putting into practice the automated systems used for university management. The authors propose the structure of an automated system, which allows the university to create the required package of teaching documents taking into account the three-level system: administrator, supervisor of educational program, and lecturer. Designing object-oriented model in the area of a special subject requires identification of business-requirements to the system. On the basis of the model of subject area and specified business-requirements, the diagram of applying variants and the schemes of functioning is constructed. The suggested system of the automated execution of teaching documents enables to reduce error rate while carrying out and implementing it due to the integrated system of conceptions and feedback between its elements

Studies of concentration and temperature dependencies of precipitation kinetics in iron-copper alloys using kinetic monte carlo and stochastic statistical simulations

The earlier-developed ab initio model and the kinetic Monte Carlo method (KMCM) are used to simulate precipitation in a number of iron-copper alloys with different copper concentrations x and temperatures T. The same simulations are also made using the improved version of the earlier-suggested stochastic statistical method (SSM). The results obtained enable us to make a number of general conclusions about the dependencies of the decomposition kinetics in Fe-Cu alloys on x and T. We also show that the SSM describes the precipitation kinetics in a fair agreement with the KMCM, and employing the SSM in conjunction with the KMCM enables us to extend the KMC simulations to the longer evolution times. The results of simulations seem to agree with available experimental data for Fe-Cu alloys within statistical errors of simulations and the scatter of experimental results. Comparison of results of simulations to experiments for some multicomponent Fe-Cu-based alloys enables us to make certain conclusions about the influence of alloying elements in these alloys on the precipitation kinetics at different stages of evolution.Comment: 18 pages, 17 postscript figures, LaTe

CONDUCTOMETRY BIOTESTING AS APPLIED TO VALUATION OF THE PRO- AND ANTIBACTERIAL PROPERTIES OF CATOLITES AND ANOLITES

The paper deals with technique of the electrical conductivity biotesting as applied to the analysis of pro- and antibacterial activity of catolit and anolit solutions. The tested preparations were received by 25 minute electrolysis processing of 1% NaCl water solution (in cathode space) and 1% Na2SO4 water solution (in anode space) at 7 A amperage and 28 V voltage. The submitted technique is based on the analysis of change dynamics of impedance electrical conductivity of researched samples, caused by metabolic processes, realized by tested microorganisms in analyzed samples. Application of this technique enabled to show that makeup anolit solution, beginning from concentration equal to 1 vol. %, has a bacteriostatic effect on liquid culture medium with Escherichia coli in the quantity of 104 live cells on 1 ml. At anolit solution concentration more than 5 vol.% its action on the same microorganismes becomes bactericidal. At the same time, makeup catolit solution activates microorganismes vital activity as early as from concentration equal to 5 vol.%. Thus, it is shown, that electrical conductivity biotesting is a sensitive laboratory tool, granting accessible, convenient and informative way to a researcher for valuation of properties of various pro- and anti-infective preparations, as well as the other physico-chemical systems (including rather complex concerning structure and dynamics of its change), capable to act on microorganismes vital activity

The use of ridge regression for estimating the severity of acute pancreatitis

Purpose. Increasing of treatment efficiency for patients with acute pancreatitis by improving objective means of determining the severity of acute pancreatitis.Materials and method. The study was based on a retrospective analysis of 130 cases of acute pancreatitis: 47 cases from «Krasnoyarsk Regional Clinical Hospital» and 83 cases from «Regional Interdistrict Clinical Hospital No 20 named after I.S. Berzon» in the period from 2015 to 2017. The raw data was pre-processed. In particular, different methods (median, linear regression) were used to fill the missing values in the observation matrix. The initial dataset contained features measured in various quantitative and categorical scales. For some features with a pronounced asymmetric distribution, a quantile transformation was applied to initial values. The quantile transformation allows features to be brought to a uniform distribution in order to reduce the risk of excluding significant features. Ridge regression was used in combination with an algorithm for sequential reduction of attribute space.Results. The classifier of three degrees of acute pancreatitis severity was developed. This classifier can help to determine better treatment tactics. During validation, the method of determining the severity of acute pancreatitis classification has proven to be effective. The average accuracy was 92% compared to the experts’ decisions. This procedure for constructing a classifier can be used as part of the basis to the medical decision support system.Conclusion. The results of this study will help to make the choice of a necessary starting therapy, assess the need for surgical intervention and in severe cases, prescribe enhanced antibacterial and detoxification therapy. This will predictably reduce the percentage of septic complications of acute pancreatitis, and consequently will reduce the frequency of fatal outcomes
