Abstract
Ketone testing is an important element of the self-management of illness in type 1 diabetes. The aim of the present study was to see if a breath test for acetone could be used to predict quantitatively the levels of the ketone betahydroxybutyrate in the blood of those with type 1 diabetes, and thus be used as an alternative to capillary testing for ketones. Simultaneous capillary ketones and breath acetone were measured in 72 individuals with type 1 diabetes attending a diabetes clinic and on 9 individuals admitted to hospital with diabetic ketoacidosis. Capillary blood measurements ranged from 0.1 mmol l−1 (the lower limit of the ketone monitor) to over 7 mmol l−1, with breath acetone varying between 0.25 and 474 parts per million by volume. The two variables were found to be correlated and allowed modelling to be carried out which separated breath acetone levels into three categories corresponding to normal, elevated and ‘at risk’ levels of blood ketones. The results on this limited set of participants suggest that a breath acetone test could be a simple, non-invasive substitute for capillary ketone measurement in type 1 diabetes.

Published: October 2020

Abstract
The organization of ensuring safe execution of building and assembly works when erecting and reconstructing buildings (structures) of various purposes based on the application of trapping nets to prevent industrial injuries in case of human or items falling from height is presented. Structural layout of a safety (catching) device with pivotally mounted brackets and a freely hanging net was considered. Appearing dynamic loads in case of items falling on trapping nets depending on impact acceleration were theoretically identified. It was found out that a trapping net with pivotally positioned brackets additionally reduces deceleration loads in relation to devices with rigidly fixed brackets and their use is more effective for cases of men falling with insignificant forward velocity. Bench and shop tests of trapping devices were carried out with the purpose of checking compliance of selected theoretical models, selection of developed options of designs and schematic diagrams, differentiation of reaction of capron and lavsan net materials from action of impulse loads. Test key results confirming matching of experimental data with presented theoretical models were showed. It was established that dynamic overloads depend both on a bracket position angle as well as on a place of an item falling into net, the value of pitch of deflection of net cloth made of lavsan and capron materials is almost similar and characteristics of values of their displacement under dynamic loads from a falling item are identical.

Methods for constructing intersection lines of surfaces are developed using the Dragilev’s method. Construction methods are considered by reducing the solution of the problem to the Cauchy problem. And a solution without reduction to the Cauchy problem. The geometric model is also used to solve some transport problems: visualization, construction of calculation grids, etc. The solution is presented for planes specified in parametric form and for planes specified in parametric form. The article has examples of creating virtual models that explain the construction of intersection lines of various planes. The texts of the programs are presented. For example, they illustrate the capabilities of the method of constructing intersection lines of planes, which is performed in the MathCAD 11 system. Computer models help visually convert information in a two-dimensionspace into a three-dimension space and, conversely, a three-dimension space into a two-dimension space. The method described is relevant for use in computer-aided design systems. This approach can be used to solve problems in the field of descriptive geometry.

Abstract
Modern processes taking place in the global economy testify to the increasing role and importance of international transport infrastructure. The geo-economics situation of the country, the attraction of transit freight flows, the rational organization of the passage of foreign trade cargo largely depends on the degree of integration of the national transport and logistics market in the international market. Among the priorities of its work until 2030, Russian Railways notes the development of the Trans-Siberian Railway as a transit transport artery. It is assume that its development is able to transfer the Asia-Europe transit flow and back from sea to rail. Switching transit freight flows from sea to rail is also one of the tasks and the revival of the transport route between East and West, announced by China as a large-scale transformation of the entire trade and economic model of Eurasia. This concept of a new pan-Eurasian (and in the long term intercontinental) transport system is based on a historical example of the ancient Great Silk Road, which has been in operation since the 2nd century. BC e. and was one of the most important trade routes in antiquity and in the middle Ages.

Abstract
The relevance of the research topic is determine by the fact that the effectiveness of the logistics complex of the whole country depends on the quality of decisions on the creation of terminal systems in the regions. The state and development of industry, agriculture, defense of the country and, in many respects, well-being and convenience for the population depend on the quality of the functioning of the transport system. Integrated directions, the tasks of which would be a multifactorial study of such complex logistic entities as terminal networks are still not sufficiently study in modern transport science. The scientific article proposes an evolutionary-functional approach to the classification of transport nodes, which be used as a technique for studying the features of the origin and development of transport nodes. The pyramid of terminalistics and the hierarchy of its objects is present taking into account the complexity and integration of the service as an adapted version, according to the theory of J.-P. Rodrigue. For railway junctions, a four-stage adapted Rodrigue-Notteboom model is propose. The stages of the development of the transport hub according to the evolutionary-functional approach are investigate. A model for the development of logistics facilities is propose (for example, Venlo Trade Port). It is summarized that the development of transport hubs can be effective for industries not related to transport and warehouse logistics, but for such industries, the development of transport hubs will have social and financial effects.

Abstract
Improving the quality of passenger service by public transport is a priority in major cities of the Russian Federation. One of the important indicators of the quality of transport services in passenger transport is the regularity of transportation, which, in addition to the planned traffic intervals, also depends on factors related to the conditions of public transport in the settlement (the intensity and composition of the traffic flow, the structure of passenger traffic, the mode of traffic lights, atmospheric conditions). The article analyzes the regularity of urban public passenger transport in the conditions of the city of Ryazan, by studying the intervals of arrival of vehicles at stops along a given route. According to the results of the study, serious problems were identified in the existing route network, and measures were outlined to eliminate shortcomings in the operation of urban transport by optimizing the city route network.

Abstract
Ensuring comfortable and safe conditions for visitors to large-scale events of various kinds is one of the priority areas for the organizers. There are many examples when insufficient attention was paid to security issues, which led to sad consequences for the audience. Mistakes in planning evacuation routes in emergency situations are the main cause of panic for a crowd of people. Victims of the evacuation can be avoided with a well-organized system of informing the audience and a pre-planned visual orientation with signs and arrows, as well as sound. Visitors should be instructed and aware of the routes and exits that should be used in case of emergency evacuation. This article discusses the possibility of creating the necessary prerequisites for improving the safety of pedestrians participating in mass events. The presented study is aimed at forming the necessary foundations for developing recommendations to improve the safety of events with a large number of participants.

Published: October 2020

Abstract
In modern automobile transport, the methodology of probabilistic estimates of the time between failures of automobiles, which has been developed over decades, is not used, and manufacturers do not include data on their reliability in the characteristics of automobiles. With their distribution of cars on flights and routes, the motor transport enterprises do not calculate the margin of their performance before repair or maintenance. The aim of this work is to substantiate automation methods for a comprehensive reliability assessment of a car and determine the residual life before setting up for repair or maintenance. It is proposed to use for these purposes statistical estimates of the operating time parameter between statements for repair or maintenance and their change as the vehicle develops a resource. A new service for the on-board local area network of vehicle has been developed to automatically monitor the performance margin. It is based on a joint automatic control of statements for repair or maintenance and calculation of vehicle operating time between them. The proposed control is intended to be implemented by means of the on-board local area network of the car and the information system for supporting the technical operation of cars at the motor transport enterprise.

Published: October 2020

Abstract
The relevance of the research is that despite the already studied method of evacuation modeling, it is not widely used, especially in Russia. There is also a tendency to an increasing destructive capacity of the heart rate, which increases the probability of complete evacuation of the population and material assets. The purpose of this article is to develop and test a simulation model that allows you to calculate the characteristics of a locality and transport infrastructure, allowing you to predict the process of evacuation in advance of the appearance of negative emergency factors. The model was developed based on the Anylogic software product. As a result of the experiments, indicators were obtained, which can be used to make a conclusion about the possibility of evacuation in the selected locality.
