Abstract
In today's world, China occupies important, if not leading, positions in its region in various industrial sectors, and therefore the question of the possibilities of delivering a very large amount of Chinese products, including ways and means of delivering goods from China to Europe and back, has now become very serious. The last decade, China has actively proclaimed a policy of openness and carries out a huge number of various reforms. Thanks to this, China was able to sign many documents with European countries on cooperation in various fields - economy, trade, science, technology, culture, and in the field of civil aviation, road, rail, and maritime transport. In addition, directly with the EU - general trade agreements. Such cooperation leads to a change in the structure of trade and economic relations, because of which the customs relations of the PRC with members of the Eurasian Economic Cooperation (EAEU) change. The article is devoted to the Chinese project "New Silk Road". The cargo flows of the project “New Silk Road” investigated. It was determined that sea freight is the most profitable way to deliver goods from China to Europe. The transit channel between Europe and Asia is consider as a way to develop an international logistics system in the territories adjacent to Asia and Europe.

Abstract
In conditions of general liberalization of transport processes, maintaining the state’s regulatory role for coordinating transport sectors and links in the transport chain, international transport cooperation and developing international transport corridors, it is necessary to take into account that when organizing export transportation of raw materials one of the problems remains an objective assessment of their cost and based on it transportation charges with confirmation of permission to export goods from the customs territory of the Russian Federation, which authors try to resolve in the given research. Rail transport plays an extremely important role in the development of the economy of any state, since, by transporting goods in accordance with the needs of production, it ensures the normal functioning and development of all its industries, regions and enterprises. Rail transport is a vital branch of the economy that ensures economic security and the integrity of the state. The search for ways to increase the efficiency of transport and its component — international transport of raw materials — is an important area of a number of economic studies. This topic has become the subject of active study by Russian scientists. The article proposes an algorithm for improving the organization of transportation using the example of SWIFT RUS. The authors rightly note that the introduction of customs services at railway border crossings will allow transport companies to receive stamped electronic documents immediately after passing the state border container train.

Authors: Vorobyov S , Bakaeva N , Poturaeva T , Kozlov D 
Published: December 2019

Abstract
In modern conditions, urban development is impossible without concentration of population, industry and transport in a limited area. The environmental pollution reaches such proportions that the positive effect of keeping emission of pollutants at the level of the MPC is leveled by number of pollution sources, their concentration in a limited area and the synergistic effect of the pollutants on human health. There is a need to assess the quality of the urban environment. This is especially important inside city blocks. Residential areas are separated from industrial by sanitary protection zones, but road transport easily penetrates into a residential area and its emissions affect public health. The methods of bioindication is a quick, affordable and cheap way to assess the quality of the environment. Bioindication methods are also a reliable source for determining the integral indicator of the biospheric compatibility of urban areas.

Published: December 2019

Abstract
Initial solution treatment (ST) of aluminium alloys prior cryorolling (CR) enhances the ultrafine grain structure formation hence, improving their mechanical and corrosion properties. However, determining the appropriate ST temperature is crucial to obtain the optimum properties. In this work, ST followed by cryorolling of AA 5052 alloy was performed at varying temperatures; 480 °C, 510 °C and 540 °C. Mechanical and microstructural characterization of the cryorolled samples with and without ST and the base metal were performed using Vickers hardness tester, universal tensile testing machine, FESEM, EBSD and HRTEM. All the ST cryorolled samples showed the finer structure and better mechanical and corrosion performances than those without ST and the base metal. The smallest crystallite size and lattice strain achieved were 24.88 nm and 3.86 × 10−3 respectively at 540 °C. The hardness, yield and tensile strength increased with increasing the ST temperature with the highest values of 85.2 Hv, 254.82 MPa and 303.35 MPa, respectively, at 540 °C. Cryorolled sample solution treated at 540 °C also showed the highest corrosion resistance based on low corrosion current and high corrosion potential. The work gives the appropriate ST temperature at which improved microstructure, mechanical and corrosion properties of the cryorolled AA5052 can be obtained.

Published: December 2019

Abstract
Hydrophobically associated (HA) hydrogels have attracted great concerns with their admirable properties, such as self-healing and shape memory. However, a few works have been devoted to apply HA hydrogels in practice, especially in wastewater treatment. This may be because of the non-ionic monomer composition and the poor mechanical properties after swelling. In this work, in order to improve the mechanical properties and absorption behavior of HA polyacrylamide (HPAM) hydrogel, hydrophobically associated polyacrylamide/cellulose nanofiber (HPAMF) composite hydrogels were prepared. It was found that by incorporating CNF (2 wt%), the tensile strength (≈0.276 MPa) was largely increased by 632% compared to HPAM hydrogels. The maximum Cu ion adsorption capacity of the HPAMF hydrogel (containing 2 wt% CNF) was 2.33 mmol g−1, about 86% over the HPAM hydrogel. The HPAMF hydrogels with self-healing, excellent mechanical and adsorption properties can be promisingly served as reliable absorbents, consequently satisfying the needs of practical application of heavy metal treatment.
