FMD risk in the Russian Federation dictates the need for enhanced measures aiming to prevent the introduction of FMD virus and comprising systematic monitoring research and mass vaccination of susceptible animals in the buffer zone. Research into the development of vaccines for early protection confirm that their use induces the formation of virus-neutralizing antibodies in naturally susceptible animals in the outbreak area, which protects from FMD infection, limits its spread and contains it within the primary outbreak. Taking into account the high speed of the infection spread, such a control measure as using FMD vaccines which induce early protection should be adopted immediately after the occurrence of the outbreak. The article presents the results of the research into the formation of humoral immunity in naturally susceptible animals triggered by administration of inactivated emulsion FMD vaccines capable of ensuring early protection against type O FMD. Culture FMD virus of О/Primorsky/2012, О/Saudi Arabia/08 and О/Mongolia/2017 strains was used for vaccine production. Immunogenic activity of vaccines was tested in cattle, pigs, and sheep. It was found that monovalent emulsion FMD vaccine based on О/Mongolia/2017 strain induced the formation of virus-neutralizing antibodies in the quantity necessary to protect against the homologous strain in seven days after a single administration in the dose of 2 cm3 . Vaccines based on О/Saudi Arabia/08 and О/Primorsky/2012 FMDV strains can protect animals from infection with heterologous О/Mongolia/2017 strain at early stages if a double dose is administered. Vaccines based on the above-mentioned strains induce early immunity formation (seven days after vaccination) against type O FMD. We suggest using the given products in the zones of a higher risk of the virus introduction.

The Structure of the Silumin Coat on Alloy Cast Steels The work presents the analysis results of the structure of the coat obtained by dipping in silumin AlSi5 of two grades of alloy cast steel: GX6CrNiTi18-10 (LH18N9T) and GX39Cr13 (LH14). The temperature of the silumin bath was 750±5°C, and the hold-up time of the cast steel element τ = 180 s. The absolute thickness of the coat obtained in the given conditions was g = 104 μm on cast steel GX6CrNiTi18-10 and g = 132 μm on GX39Cr13. The obtained coat consisted of three layers of different phase structure. The first layer from the base "g1" was constructed of the phase AlFe including Si and alloy additives of the tested cast steel grades: Cr and Ni (GX6CrNiTi18-10) and Cr (GX39Cr13). The second layer "g1" of intermetallic phases AlFe which also contains Si and Cr crystallizes on it. The last, external layer "g2" of the coat consists of the silumin containing the intermetallic phases AlFeSi which additionally can contain alloy additives of the cast steel. It was shown that there were no carbides on the coat of the tested cast steels which are the component of their microstructure, as it took place in the case of the coat on the high speed steels.

The article discusses communication facilities for transmitting corrections and ephemeris data, analyzes methods of calculating errors of satellite position finding, and gives results of field tests for determining accuracy of the location for Real Time Kinematic and Precise Point Positioning modes. There has been carried out a survey of the existing functioning differential satellite subsystems, satellite differential correction and monitoring systems. The methods of differential coordinate correction currently used on the inland water transport provide accuracy within 1-5 meters. As in the unmanned mode the given accuracy is not sufficient, there appears the need to develop methods for calculating location finding with centimeter precision. Precise positioning relative to the axis of the ship's course will make it possible to control the vessel in the unmanned mode, as well as to use robotic facilities on water transport capable of making safe voyages on a set of waypoints tied to geographical coordinates.

Abstract In many countries, open and distance education is perceived as a way to meet the growing need for higher education. This paper explores the development of online and distance education in three countries that are still a white spot on the landscape of international distance education research although they have implemented elaborated distance education systems: Turkey, Russia and Saudi-Arabia. In order to understand the current state of distance education systems in the three countries, their respective systems are described from a historical perspective, compared in regard to their organization, important institutions for open and distance education and current developments. This comparative analysis directs the focus on little investigated education systems and contributes to an enhanced understanding of their past, present, and future.

The Impact

The article reviews the world experience in the construction and operation of high-speed railways in terms of factors that determine the success or failure of such projects. Since the construction of HSR is often considered as a part of national projects on a broader scale, it is proposed to use as criteria for success not only commercial indicators, but also various socio-economic effects arising from their implementation. The author classifies externalities that reflect the impact of HSR on the development of regions and cities and presents the results of foreign research on their quantitative and qualitative analysis. Special attention is paid to the experience of China, since this country significantly differs from the rest of the world in terms of development of high-speed rail traffic. In this regard, the largest amount of representative data that allows us to identify the success factors of HSR projects can be found for Chinese projects. The main scientific result of this article is a generalization of the existing experience of HSR construction projects and justification of the prospects for implementing such projects in the Russian Federation.
