See the frist part in: World of Transport and Transportation, 2018, Vol. 16, Iss. 2. ABSTRACT In the last decade, many researchers focused on improvement of environmental friendliness and on the principles of sustainable development, green logistics became a new field of transport research. The article presents an overview of the research in this area using as an example foreign and Russian projects. It is shown that the existing approaches, methods and instruments of «green» logistics are scattered, their use leads to making contradictory decisions that do not contribute to a systematic reduction of the harmful impact of transport on the environment. The authors proposed their approach to systematization of principles and methods of «green» logistics, which will allow creating more balanced programs to improve the environmental friendliness and efficiency of transport systems. The second part of the article (the first part was published in previous issue of World of Transport and Transportation) is dedicated to the features of object environment. Keywords: transport, sustainable development, green logistics, logistics, ecology, environment The work was carried out with the financial support and within the framework of the international educational project of the European Union TEMPUS EcoBRU «Environmental education for Belarus, Russia and the Ukraine» (543707-TEMPUS-1-2013-1-DE-TEMPUS-JPHES).

DEVELOPMENT OF RAIL FREIGHT CARRIAGE: GLOBAL TRENDS
Authors: Karapetyants I. V.
Published: October 2022

ABSTRACT European experts believe that development of high-speed rail requires upgrading of existing technologies and transport infrastructure, changing organization of traffic, and control and management system. In addition, new standards of safety, environmental friendliness, sustainability, better means of signaling and control are needed. It is believed that the US rail cargo traffic service has made progress through specially allocated tracks and reduced downtime. In Europe, introduction of such projects is still impossible, which leads to long delays in rail cargo delivery. Downtime is due to the fact that priority is given to passenger trains, as well as to violations in operation of signaling systems, inefficiency of loading and unloading of goods. At the same time, organization of services in the sphere of express delivery of goods in Europe is considered as the most important task that will result in reduction of technical and bureaucratic barriers at the national borders, and will help to attract new markets, clients, customers to the railway sector. Keywords: high-speed cargo traffic, railway transportation, communication control systems, traffic delay, regularity of transportation, speed of delivery of goods, high-speed traffic mode.

Authors: Say V. M. , Kochneva D. I.
Published: October 2022

ABSTRACT The article is devoted to development of a model for substantiating a region’s need for containerization of cargo transportation. The model includes two interrelated elements: a method for substantiating container suitability for cargoes and an imitation algorithm for planning of the region’s need for containerization. The planning of the need for containerization links the demand of enterprises for transportation (taking into account the levels of product container suitability) and the available resources of the container transport system (terminals, container fleet, rolling stock). Further development of the model assumes assessment of costs and benefits of the region from development of the container system. Verification of the simulation model at the example of Sverdlovsk region demonstrates its efficiency and adequacy of reality. Keywords: container transportation, containerization, container suitability of cargo, social and economic system of the region, development of the region, resources, simulation model, organization of interaction.

STRUCTURAL OPTIMIZATION OF PIPELINE SYSTEMS DURING THEIR DESIGN AND RECONSTRUCTION
Authors: Tararychkin I. A.
Published: October 2022

ABSTRACT The study considers peculiarities of structural optimization of pipeline transport systems that help to ensure the required level of their resistance to development of the process of progressive blocking of nodes. It is shown that the highest level of resistance of network structures to consistently increasing risks of damage is achieved in systems with the largest composition of the subset G1 (source to consumer links), under the condition of high valence of the source node of the target product. The valence of an individual system node is a number of pipelines converging into it, and the linear elements connecting directly the source and consumers of the product are considered to belong to the subset G1. The established regularities allow solving the problems of searching for optimal network structures that are resistant to development of emergency situations, by the mechanism of progressive blocking of nodes in design and reconstruction of pipeline transport systems. Keywords: transport, system, pipeline, structure, optimization, damage.

MATHEMATICAL MODELING OF TRANSVERSAL CREEP OF RAILWAY WHEELS
Authors: Korolkov E. P.
Published: October 2022

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT Analyzing the analytical expression of transverse creep used to model the forces of interaction between a wheel and a rail, it is possible to note that the formula for its calculation does not physically correspond to the definition of creep as the difference between kinematic and actual displacements. In fact, the formula contains the difference between real transverse and longitudinal rotation, multiplied by an angle, displacements of the center of mass of the wheel set. If the direction of movement of the wheel set does not coincide with the track axis, the deformation of the contacting fibers of the wheel and the rail occurs in the direction of movement of the center of each wheel. However, the formula for calculating the transverse creep, in contrast to the longitudinal creep, is in no way connected with the contact between the wheel and the rail. Two physically justified variants of calculating the transverse creep are proposed, which can lead to nonlinear differential equations describing the plane motion of a wheel set or a bogie. Keywords: railway, rail, wheel, contact spot, actual displacement, creep, track axis, modeling, projection.
MONITORING OF INFRASTRUCTURE OF TRANSPORT AND LOGISTICS COMPANIES
Authors: Freidman O. A.
Published: October 2022

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT The quality of services provided by transport organizations depends largely on the state of their logistics infrastructure. High differentiation of companies in the contract logistics market makes it difficult to select a partner, which may lead to a decrease in the level of order service. The subject of the analysis is the logistics infrastructure of transport companies performing logistics services. The objective of the study is to develop indicators for assessing the logistics infrastructure of transport companies as partners of focus companies, e. g. of JSC Russian Railways, in supply chains. Following this purpose, the article proposes to introduce a process approach to assessing the logistics infrastructure of transport companies, starting by offering an approach to the notion of logistics infrastructure. It is assumed that the use of a suggested multilevel set of criteria for assessing the logistics infrastructure, simultaneously with the results of the logistics activities of partner companies, and monitoring of these data will solve the following tasks: automate the process of collecting and processing data on transport companies as participants in supply chains; reduce the time for analysis and selection of a partner in the supply chain, taking into account its infrastructure characteristics and performance in previous periods; in the future will allow to move to digitalization of the process of organizing the supply chain and increase the segment of high margin transportation, by reducing the delivery time and increasing the quality of logistics services. Study of proposed criteria was conducted at the example of Irkutsk region. Keywords: logistics system, infrastructure, transport and logistics service, market, transport and logistics company, logistic process.
RESERVES FOR INCREASING RAILWAY CAPACITY
Authors: Levin D. Yu. , Sokolova V. B.
Published: October 2022

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT Reserves for increasing the capacity of railways, among other things, are associated with the possibilities of reducing the length of block sections and reducing the spatial and temporal inter-train interval. The actual length of the block sections, determined by the inter-train interval, is considerably greater than the estimated length required for traffic safety. The similar arrangement of traffic lights leads to an underestimation of the available throughput. To bring the lengths of the block sections into line with the braking distance, it is suggested to consider the movement of trains at the yellow indication of the traffic light without reducing the speed. Reducing the braking distance, the length of the block sections and their number will increase the carrying capacity, especially in the areas of freight traffic. Satellite radionavigation systems that regulate traffic without floor traffic lights and rail chains can help to ensure the minimum required interval between trains. Keywords: railway, throughput, length of the block-section, braking distance of the train, inter-train interval, arrangement of passing traffic lights, satellite navigation.

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT Reducing costs in material flow of goods as a result of optimization of parameters of cargo movement in automotive transport and logistics systems requires the development of a mathematical apparatus, adapted to the task. Its most complete solution can be obtained if the problem is considered as multi-criteria. The article presents a formalized structure of criteria, allowing to optimize the interaction of objects of the logistics infrastructure of transport and warehouse services and freight road transportation. The choice of criteria for efficiency of the transport and logistics system (TLS) is based on effective indicators, which in turn are determined taking into account the indicators of the use of the means of production in certain conditions of the operating environment. The criteria system considered in the article is a decomposition of the hierarchy of TLS criteria that determine the organization of freight road transportation (FRT) and functioning of transport and storage complexes (TSC). The choice of performance criteria is based on the effective indicators of FRT and TSC, which in turn take into account the indicators of the use of means of production in the conditions of the environment of operation. Integration of FRT and TSC criteria into a single structure allows to solve multiple tasks. Keywords: transport and logistics system, road freight transportation, transport and warehouse complex, management, efficiency criteria, performance indicators, operating environment, indicators of the use of means of production.

Authors: Shiler V. V. , Shiler A. V.
Published: October 2022

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT The data presented in the article testify to the urgent need for modernization of methods for studying horizontal geometric irregularities that provide necessary accuracy in assessment of the rail gauge state. The method for measuring the trajectory of the lateral surface of the rail head in the horizontal plane is improved. The method of converting the bending arrows from the base chord to the absolute values of the coordinates of the trajectory of the lateral surface of the rail head in the plan is modified. The influence of lateral wear of rails on traffic safety is evaluated. Particularly, the authors argue that along with the spectral methods of estimating the horizontal irregularities, it is necessary to apply the indicator of the traffic safety factor of single irregularities. According to the research the lateral undercut of the rail head in the longitudinal direction has an uneven wavy character and the results of its measurements should be used in assessing traffic safety, especially in curved sections of the track. Keywords: railway, track measuring car, horizontal irregularity, rail gauge, side wear of rails, traffic safety.

The possibility of the scheme is shown on the basis of a group of similar modules in the form of surface vessels with two generators of vortex pairs of a family of essentially new types of water vessels - self-contained multipurpose units with an almost unlimited period of autonomous functioning in an arbitrary non-freezing water area of the World Ocean. It is established that in all parameters, in addition to speed, vessels with vortex propulsion units have advantages over their competitors. Keywords: vortex propulsion units, water and aeronautical vessels, surface and underwater (toroidal) vessels, mass-dimensional characteristics, layout schemes, operational parameters.

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT Screw-nut transmissions are used in control mechanisms to convert rotary motion to forward motion or vice versa. The authors propose a technique for determining the strength and wear resistance of screw-nut sliding transmission based on the solution of the contact problem for its radial section, taking into account the difference in the materials of the transmission parts. The object of the study is a screw that is made of steel, and a tin bronze nut. The article presents the solution of the problem for the trapezoidal thread profile, the basic step-by-step actions in ANSYS 10 ED, as well as the parametrized code APDL, allowing to choose the optimal geometric parameters of the transmission and the mechanical parameters of its details in terms of durability. Keywords: mechanics, screw-nut transmission, stress state, finite element method, ANSYS, parametric model, motion transformation.

In order to reduce resource intensity of the transport process and the cost of transport work, a number of methodological recommendations on identification of spare parts, fuel and tires reserves accumulated and unclaimed during road transportation have been proposed. Examples of practical implementation of the proposed recommendations are given. Particular emphasis is placed on the fact that the funds used do not require additional costs from carriers and bring obvious economic benefits. Keywords: road transportation, transport process, consumption rates, material resources, production efficiency.

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT The article highlights the urgency and specificity of high-speed railways in Russia. The specifics of accounting for the cost of construction of HSR are indicated. The necessity of evaluating project solutions based on the technical and economic comparison of options is substantiated. Present and prospective technical solutions and technologies for construction of HSR are given, possibilities for further transition to the overpass method of their erection are considered. A comparative analysis of the estimated cost of construction of HSR-2 Moscow-Kazan and similar analogues, whose projects are implemented in international practice, are presented. The authors argue that the high-speed railway line Moscow- Kazan is unique, technically complex, the first in Russia infrastructure project of this level. Compliance with the requirements of the terms of reference, regulatory documents and the application of best practices of foreign countries have a determining effect on the estimated cost of construction. In comparison with the railways of the common network with train speeds of up to 200 km/h, the HSR-2 project significantly exceeds the share of the main construction sites (by more than 36 %). The presented data confirm that the cost of project solutions with the increase in the speed of trains by more than 200 km/h is interdependent from the increase in the requirements for safety and continuity of movement of high-speed railway transport. The editorial board reminds that all interpretation of facts and the conclusions lay exclusively in the sphere of authors’ responsibility. Keywords: railway, high-speed highway, construction, technical and economic comparison, cost of line, cost of technical solutions, roadbed, ballastless track superstructure, HSR in the world.
Degenerative Mitral Stenosis—Diagnostic Challenges and Future Directions
Authors: Joury Abdulaziz , Puleo Christopher , Golive Anjani , Gilliland Yvonne , Pressman Gregg S. , Qamruddin Salima
Published: October 2022

Determining the severity of stenosis in degenerative mitral stenosis (DMS) is fraught with challenges. Neither a high trans-mitral gradient nor a small valve area calculation is sufficiently diagnostic for DMS due to variable left atrial and left ventricular compliance in the setting of diastolic dysfunction, and the variable flow seen in patients with chronic kidney disease (i.e., high flow state) and elderly women (low flow state). Three-dimensional measurement of mitral valve area may be underestimated due to shadowing from basal calcium, and mitral valve annulus (MVA) by continuity equation (CEQ) or dimensionless mitral valve index can be erroneous in the presence of significant regurgitation of left-sided valves. The proposed dimensionless mitral stenosis index (DMSI) can be an easy echocardiographic tool to use in daily practice but needs further validation and is limited in the setting of significant regurgitation of left sided valves. Mean trans-mitral gradients >8 mmHg and pulmonary artery pressure >50 mmHg are independent predictors of mortality in those with MVA <1.5 cm2 derived by CEQ. In patients who have symptoms that are out of proportion to the degree of stenosis reported, exercise stress testing may help determine the physiologic effects of the stenotic valve. A combination of MVA by CEQ or DMSI and mean transmitral gradient at a given left ventricle stroke volume (flow) should be evaluated in larger studies.
"Russian crusaders" in Serbia in 1876 – the only hope for salvation

Published: October 2022

The Principality of Serbia declared war on the Ottoman Empire in 1876, although it was completely unprepared either militarily or financially for such an undertaking. Torn between a historic obligation to respond and protect its disenfranchised brethren under Ottoman rule and the fact that all diplomacy, and especially Russian officials, are advising it to keep the peace, the Principality of Serbia finds itself in its death throes.
