Authors: Dmitrenko A. V. , Kolosova M. A. 
Published: July 2021

The development of stationary energy seems to be an important aspect of introduction of energy-saving technologies in transportation sector. In Russia, it is conditioned by the main provisions of the Energy Strategy of the Russian Federation until 2030. In this regard, the problem of efficient use of low-grade heat based on the organic Rankine cycle (ORC) in stationary heat energy supply units in the transport industry is urgent. In particular, this task is typical for boiler houses converted from heavy fuel oil to gas fuel. In this case, the efficiency of ORC application will primarily be determined by the efficiency of the used heat exchangers (HE) with a phase transition, as a result of which, both technically and theoretically, the problem of designing and calculating the optimal characteristics of these HE will be of great interest.The article presents a theoretical and computational model of heat transfer during phase transitions in turbulent flows based on the relations obtained by the stochastic theory of hydrodynamics and heat transfer. The modelling of the effect of turbulence during the phase transition with undeveloped boiling of the bubble mode is considered. The comparison results show satisfactory conformity of the values obtained according to the formula based on stochastic equations with the values calculated according to the empirical formula for the flow in a pipe, used in the engineering method of designing heat exchangers. The results obtained open the prospect for studying the processes of heat transfer during phase transitions in turbulent flows of HE to reduce their overall and mass characteristics, as well as to increase the energy efficiency of both the devices themselves and the efficiency of the entire energy complex.

Models of Organisation of Combined (Mixed-Mode) Passenger Transportation
Authors: Guts A. V. 
Published: July 2021

The article examines business models for mixedmode (combined) passenger transportation and development of combined passenger transportation as a factor in the growth of capacity of the railway passenger transportation market. The crisis in the transport services market, caused by non-economic factors (COVID‑19 pandemic), is characterized by a classic combination of supply shocks and demand shocks for passenger transportation, which increases relevance of the problem of searching ways to rise the volume of passenger traffic, in particular, by rail, demand for services provided to the public using railway assets.The current approach to increasing the demand for railway passenger transportation by developing the railway route network, improving the equipment of railway stations and the quality of service, expanding the range of services offered, promoting everything that encourages the consumption of services by a larger number of customers, will remain important. Nevertheless, this approach should be critically considered and supplemented in the light of new economic trends motivated by digital technology. That is especially important today, when, in conditions of resource constraints, a strategic organisational solution is needed aimed at scaling a business, achieving an optimal «balance» of costs, quality, competencies, flexibility and customer focus.The organisation of combined passenger transportation involves active «horizontal» interaction of various transport organisations, both among themselves and with different cohorts of passengers with their own consumer preferences and income restrictions. Therefore, the transition from linear business processes built «vertically» to horizontal business processes that offer specialised packages of services through a «single window» system according to uniform standards based on digital technologies is relevant.The article proposes models for organising network interaction of participants in the passenger transportation market based on digital technologies to ensure «seamless» mobility of the population with the consolidating role of railway transport. Specific models for organising combined railway transportation should be based on a specific business model, the choice of which is determined by a strategic decision of the company.

Published: July 2021

The authors set the goals: to assess the socio-economic importance of construction of intermodal transport infrastructure in the Russian Federation in modern conditions, to analyse the degree of development of issues of assessing the economic efficiency of intermodal aspects. To achieve these objectives, the content of modern strategic documents (such as the Comprehensive Plan for Modernization and Expansion o f Trunk Infrastructure, the Long-term Development Program of JSC Russian Railways until 2025, the Spatial Development Strategy of the Russian Federation, etc.), as well as the dynamics of container traffic volumes and results in construction of new and modernization of existing intermodal transport infrastructure were analysed. Based on this, a conclusion was made about relevance, importance, and prospects of development of intermodal transport infrastructure for both passenger and freight transportation.The degree of elaboration of issues of assessing the economic efficiency of intermodal aspects is analysed, while the historical retrospective of evolution of methods for its assessment within the framework of state or sectoral methodological guidelines adopted in the former USSR and the Russian Federation is considered. When analysing approaches to assessing economic efficiency inherent in a planned economic model, several effects from improvements associated with the development of transport infrastructure and organisation of operation are described. Against this background, the authors reveal the difference between former and new approaches, characteristic of the modern market economy.Through analysis and synthesis, conclusions were drawn for each part of the study. In the final part, using a dialectical approach, the results obtained are compared. Based on this, conclusions were made on the correlation between the importance of building an intermodal transport infrastructure, the degree of development of issues of assessing the economic efficiency of intermodal aspects and the prospects for development of this research area.

Authors: Kiselenko A. N. , Sundukov E. Yu. 
Published: July 2021

The relevance of the article is determined by the increasing role of the Arctic transport system in the economy of the Russian Federation: involvement of territories of the Arctic zone of the country in economic activities, an increase in their social and economic potential. The development of the northern territories is directly related to existing and future capabilities of the Arctic transport system, for successful functioning of which it is necessary to provide it with feeder transport network.The objective of the work is to determine the scenarios according to which development of these feeder roads can be carried out. When writing the article, the methods of systemic, comparative, and statistical analysis were particularly used.The paper clarifies the definition of the Arctic transport system. It is noted that scenarios for development of feeder routes to it should be linked to its general development, as well as to the development of the Arctic zone of the Russian Federation. The European and Ural Arctic subregion is highlighted, where development of feeder routes is most important in connection with the growth of economic activity on Yamal Peninsula. With reference to the works of domestic and foreign authors, strategic planning documents of the Russian Federation, it is assumed that according to the degree of achievement of target indicators of traffic volumes along the Northern Sea Route, optimistic and pessimistic scenarios for formation of feeder network can be activated. The final implementation of one of those scenarios is determined by political, natural, and other risks.When developing scenarios for formation of transport feeder network to the Arctic transport system, the emergence of new modes of transport should be considered. New modes of transport can provide linking of remote objects to the trunk transport networks or eliminate the gaps emerging in them.The use of new modes of transport in the Russian Arctic should be carried out only after testing at specialized test sites, where their safety for transportation of passengers and goods, as well as for the environment, will be determined.The work was carried out within the framework of the comprehensive program of fundamental scientific research of the Ural Branch of the Russian Academy of Sciences for 2018–2020 and is associated with the need to increase the capacity of the main ports of the European and Ural Arctic and the volume of traffic along the Northern Sea Route.

The method allows building a correspondence matrix of vehicles recorded by CCTV cameras located on different segments of the road network, as well as determining all traffic parameters for the entire street and road network.The conclusions outline the prospects for development of the developed software in terms of application in intelligent transport systems.
Evaluation of Electrophysical Properties of Soils in the Slope Zones of the Foundation During GPR Survey
Authors: Pupatenko V. V. , Sukhobok Yu. A. , Stoyanovich G. M. 
Published: July 2021

The article describes a new method for conducting a ground penetrating radar survey of slope zones of soil objects of transport infrastructure. In the lithological section of these objects, there are sub-horizontal and inclined soil boundaries, as well as slope zones. Traditional survey methods (drilling, pitting), as well as the standard GPR method, make it possible to reliably survey at these objects, as a rule, only the zones under the horizontal main ground of the subgrade and sub-horizontal sections of the ground outside its boundaries. Survey under inclined surfaces is often difficult or technically impossible; geophysical methods, just like traditional ones, provide initial information that is exceedingly difficult for further decoding. The sections are filled with re-reflections and noises, and the process of decoding them is associated with great methodological problems.This paper presents a new method for determining speed of propagation of radio waves in the slope zones of the foundation. The initial information is the data obtained during the survey using the common depth point (CDP) method, using a well-known survey technique and a standard set of hardware. The novelty of the article results is determined by the algorithm for processing the measurement results developed by the authors. The software implementation made on its basis makes it possible to obtain the hodograph equation considering the slope of the layers. Defining geometric characteristics of embankments associated with the presence of slopes of variable steepness have been considered. A technique for calculating propagation speed of radio waves for a two-layer medium with a boundary inclined to the scanning surface has been proposed. The validity of the developed method was verified using finite-difference time-domain modelling.The article provides examples of practical application of the developed method in the GPR survey of real track foundation objects (transport infrastructure objects). The method proposed in the article makes it possible to increase the informative area of the surveyed diameters. At the same time, the accuracy of the GPR method is preserved, the area of its application for obtaining reliable information is increased to 60 % of the cross-sectional area of the foundation.

O sucesso clínico de materiais resinosos é dependente de uma adequada polimerização. Diversos materiais fotoativados são utilizados frequentemente nas clínicas-escola de Odontologia. O objetivo desse estudo foi avaliar o nível de conhecimento dos acadêmicos do 10º período de Odontologia do Centro Universitário Maurício de Nassau, Recife/PE, sobre fotopolimerização, por meio de questionário. Os dados foram tabulados e analisados por meio de estatísticas descritivas, teste Qui-quadrado de Pearson e teste Exato de Fischer, com nível de significância de 5% (p<0,05). Os resultados demonstram que 83,8% dos estudantes não possuem fotopolimerizador, 72,9% não conhecem a potência do aparelho, 56,2% não sabem qual é a potência mínima ideal e apenas 8,5% sabem o nome do aparelho aferidor da irradiância / potência. Além disso, 48,5% não sabem o comprimento de onda ideal para fotoativação de resina composta e 69,2% desconhecem o tipo de aparelho que utilizam (monowave ou poliwave). Em relação ao tempo de fotopolimerização, 60,8% afirmaram utilizar 20 segundos em resinas compostas convencionais e 38,5% utilizam por 40 segundos em resinas compostas Bulk-fill. Embora 84,6% afirmem usar aparelhos fotopolimerizadores frequentemente, apenas 26,9% sabem a distância ideal da ponteira à restauração. Além disso, 51,5% relataram que fazem a limpeza e desinfecção com álcool 70GL e 45,4% usam barreira plástica. Nesse contexto, pode-se concluir que o nível do conhecimento dos acadêmicos em relação à fotopolimerização foi insatisfatório, exigindo uma abordagem e avaliação mais efetivas para que os discentes tenham consciência da importância clínica deste procedimento e suas consequências.
