Organizational-administrative Features of the Implementation of Educational Services in the Two-level System of Training of Highly Qualified Personnel

It is education - the system of formation of the nation's intellectual capital and as one of the main areas of production innovation - creating the basic conditions for intensive growth of the markets on the basis of rapid updating of technologies and products. Education acts as the first link "education - research - innovation development of mass" of the innovation cycle. This educational sphere acts not only as a necessary element of reproduction of intellectual capital, but also as a dominant element of economic growth, which determines the stability of the external and internal competitive advantages of national economic systems. From the power of the national economy play an individual and a public intellectual capital, which implements the level of economic thinking of the nation, it is largely determined by economic strength, well-being, and the choice of its strategy and the subsequent trajectory of development in a global world order. In this connection, the Russian education there are urgent tasks related to the need to comply with the transformation of the education sector changes.

Luminescent properties of Bi-doped polycrystalline KAlCl4

We observed an intensive near-infrared luminescence in Bi-doped KAlCl4 polycrystalline material. Luminescence dependence on the excitation wavelength and temperature of the sample was studied. Our experimental results allow asserting that the luminescence peaked near 1 um belongs solely to Bi+ ion which isomorphically substitutes potassium in the crystal. It was also demonstrated that Bi+ luminescence features strongly depend on the local ion surroundings

Plasma–liquid interactions: a review and roadmap

Plasma–liquid interactions represent a growing interdisciplinary area of research involving plasma science, fluid dynamics, heat and mass transfer, photolysis, multiphase chemistry and aerosol science. This review provides an assessment of the state-of-the-art of this multidisciplinary area and identifies the key research challenges. The developments in diagnostics, modeling and further extensions of cross section and reaction rate databases that are necessary to address these challenges are discussed. The review focusses on non-equilibrium plasmas

Improvement in the railway friction brake design

The article has proposed the design schemes for improvement in railway friction brakes to increase their braking capacity by reducing pressures, other conditions being equal, in the area of contact of the friction unit working elements. The effect is achieved by using ring brake linings or a brake drum in the brake friction unit. The proposed innovations make it possible to reduce the friction brake capacity by 1.7 (using ring brake linings) and 2.1 times (using a brake drum), as compared with conventional disk brakes

Дифузійне зварювання композиту на основі алюмінієвого сплаву 6061, що містить 55 % SiC з використанням наноструктурної фольги

The application of nanostructural foil for diffusion welding of composite based on aluminum alloy 6061 containing 55 % SiC = Дифузійне зварювання композиту на основі алюмінієвого сплаву 6061, що містить 55 % SiC з використанням наноструктурної фольги / B. V. Bugaenko, Y. A. Buturlia, V. V. Kvasnitskiy, V. F. Kvasnitskiy, V. N. Korzhik // Shipbuilding & Marine Infrastructure. – 2018. – № 2 (10). – P. 214–221.The process of diffusion welding in vacuum (DWV) of an aluminum-based composite using nano-multilayer aluminum–nickel and aluminum–titanium foils is investigated. Aluminum alloy 6061 hardened silicon carbide (55 at.%). It has low ductility, which makes deformation activation of the surfaces being joined difficult. Therefore, DWV perform through the intermediate layer, for example, aluminum foil. In this work, the layers obtained by the method of electron beam deposition were used. In layers with alternating nanolayers with rapid heating, reactions of self-propagating high-temperature synthesis take place, in which the amount of generated heat is sufficient for additional heating of the composite and it’s melting, which ensures activation of the surfaces to be joined. At the first stage, the creep processes of the composite under DWV conditions are investigated, the parameters and the creep equation are determined, as well as the allowable deformations that do not cause cracks. For DWV, Al/Ni and Al/Ti foils with thicknesses of 20, 40, 50, and 94 microns were used. The effect of the thickness of the interlayers on the formation of compounds has been established. It is shown that, regardless of the interlayer system, at the majority of the junction metal has a composite structure with common grains and the boundary between the connected samples is not determined either by structure or by chemical analysis.Досліджений процес дифузійного зварювання у вакуумі (ДЗВ) композиту на основі алюмінію з використанням наноструктурних фольг систем алюміній–нікель та алюміній–титан. Сплав алюмінію 6061 зміцнюється карбідом кремнію (55 % ат.). Він має низьку пластичність, що ускладнює деформаційну активацію з’єднуваних поверхонь. Тому ДЗВ виконували через проміжні прокладки, наприклад алюмінієву фольгу. Застосовані прокладки, отримані методом електронно-променевого осаджування. У прокладках з поперемінними наношарами під час швидкого нагрівання проходять реакції самопоширюваного високотемпературного синтезу, внаслідок якого кількість виділеного тепла достатня для додаткового нагрівання композиту і його підплавлення, що забезпечує активацію з’єднуваних поверхонь. На першому етапі досліджені процеси повзучості композиту в умовах ДЗВ, визначені параметри і рівняння повзучості, а також допустимі деформації, що не призводять до утворення тріщин. Для ДЗВ використали фольгу систем Al/Ni і Al/Ti товщиною 20, 40, 50 і 94 мкм. Установлено вплив товщини прокладок на формування з’єднань. Показано, що незалежно від системи прошарків на більшій частині стику метал має структуру композиту із загальними зернами і межі між з’єднаними зразками не визначаються ні за структурою, ні за хімічним аналізом. На ділянках з прошарком його максимальна товщина не перевищує 9 мкм
