Aim. To assess the results of a perinatal audit of the Northwestern Federal District and to identify opportunities for a decrease in perinatal mortality. Methods. The audit of perinatal loss was conducted in two stages: (1) remote audit audit of perinatal mortality indicators; (2) medical history audit audit of cases of perinatal death of a child based on medical documentation. Held the copy of the data from the 925 medical records for 220 cases of perinatal death. The perinatal audit of the Northwestern Federal District used the Nordic-Baltic perinatal death classification. The following statistical methods were used for statistical data processing: incidence rate of a trait was determined by using frequency tables, the statistical significance of differences was tested by using contingency tables, the Chi-square criterion, along with the Pearson correlation coefficient. The statistical significance of differences in quantitative indicators was assessed by using Student's t-Test. The significance level was set at p 0.05. Results. It was found that in the Northwestern Federal District pregnancy losses III category of the Nordic-Baltic classification (gestational age newborn, more than 28 weeks, without congenital malformations and intrauterine growth restriction) is 27.5%, intranatal losses VI category of the Nordic-Baltic classification (gestational age newborn, more than 28 weeks, without congenital malformations and intrauterine growth restriction) 7.4%, the loss of newborns VIIIXI category of the Nordic-Baltic classification (gestational age newborn, more than 28 weeks, without congenital malformations and intrauterine growth restriction) 16.9%. Among children who died during the perinatal period, children of gestational age over 28 weeks significantly predominate (p=0.003). In the nosological structure of stillbirth, most of the diseases are associated with respiratory disorders (85.9%), infectious complications are 14.1%. The main causes of death of newborns in the early neonatal period are respiratory disorders 40.0% and infectious diseases specific to the perinatal period 36.0%. The assessment of the sexual prevalence of pregnancy losses did not reveal a statistically significant difference (p=0.29). The assessment of the sexual characteristics of intranatal losses showed that boys significantly predominate (p=0.003). Conclusion. The perinatal audit revealed that, in the Northwestern Federal District, the level of the mobile reserve of perinatal losses associated with managed causes is 51.8%.

Numerical modeling is performed of movement control processes in higher regions of the human brain during the planning and execution of voluntary tracking movements, based on the internal model hypothesis. Such measures as a Kalman filter, linear–quadratic estimator, and linear–quadratic regulator are used. A way of determining moments of the activation of controls is proposed, based on an analysis of the trajectory of tracking movements. Different indicators of the quality of executing tracking movements, including energy expenditure, stability, contributions from motor errors, planning, and execution, are estimated numerically. Real experimental data is obtained in tests of athletes on the national teams of Russia. Practical application of the considered measures to training is shown.

An important role in the normal development of the fetus and the successful outcome of pregnancy is played by the state of health of pregnant women. One of the significant factors of perinatal risk is anemia of pregnant women. In order to assess the level and dynamics of the incidence of anemia in pregnant women, official statistical reports and publications of the Federal State Statistics Service for 2005-2017 and Central Research Institute for Organization and Informatization of Health of the Ministry of Health of the Russian Federation for 2012-2018 were analyzed. Using a trend analysis using a trend method, a prognosis was made for the incidence of anemia in pregnant women up to 2021 in the Russian Federation as a whole and separately in the North-West Federal District. In order to assess the impact of the predictor “anemia of pregnant women” on the infant mortality rate, data from primary medical documentation was copied to 250 children who died before the age of 1 year in the North-West Federal District. It has been established that the incidence of anemia in pregnant women in the North-West Federal District significantly exceeds the average level in the Russian Federation. Provided that factors affecting the course of pregnancy remain unchanged, the incidence of anemia in pregnant women by 2021 on average in the Russian Federation will decrease to 32.2% of the number of women who have completed pregnancy, and in the North-West Federal District will increase to 37.5%. During pregnancy, the incidence of anemia in women whose child died before the age of 1 year in the North-West Federal District amounted to 44.16 ± 0.39% of the number of women who completed the pregnancy, which significantly exceeded the average figure in the district, which in 2017 was equal to 35.90 ± 0.35% (p < 0.05). A direct correlation has been established between the predictor “anemia in pregnant women” and the infant mortality rate.

Calculation of recipes of dough for bakery products is a significant and routine operation. Doughing is the main stage of technological process in bakery production. The quality of both the dough and the final product is caused by baking properties of flour and also a ratio of water, yeast, salt, sugar and cooking fat. The recipe of a bakery product is developed for the purpose of its production with the required properties due to assigned amount of components. Development of the automated calculator for calculation and correction of the recipes of bakery products is explained by the bakery technologist’s daily need in calculating the amount of components. Basic data for calculation are type, quantity and humidity of the main (flour, grain products) and additional components (sugar, butter, cocoa and others), amount of flour which is used for preparation of ferment. The technique of calculation of recipes of fermented dough and non-fermented dough is considered. There are panels for the choice of a way of doughing, for setting the amount of flour and grain products, and other components, setting additional data, and the result of calculation of recipes. The data found during the calculation of the recipe of bakery products come to the database and are used for controlling the recipes, for proper dosing. The programming language JavaScript with jQuery library is chosen. Programming is carried out in free source code editor Notepad++ The source code editor developed on the basis of Java technology has a number of advantages for industrial consumers. The main advantages are independence of the hardware platform and the operating system. Besides, development of the automated online calculator accessible on any personal computer connected to Internet network simplifies considerably the technologist’s work.

As a result of the research carried out, it was found that when the weather conditions change, the mode of movement of traffic flows, namely the speed of movement, also changes. With the constant operation of the available technological equipment, which in turn is limited by such parameters as the intensity and com-position of the traffic flow, this phenomenon leads to significant delays in traffic and often to the occurrence of road accidents. It is possible to establish a certain speed of movement when analyzing the condition of the roadway and determining its grip qualities, which are directly proportional. In the course of surveys in this direction, the relationship between the adhesion qualities of the pavement and weather conditions was determined, which became the basis for the algorithm that determines the required speed mode of movement. The implementation of the algorithm at the experimental city entrance made it possible to introduce the required speed mode and ensure the operation of the existing technological equipment taking it into account. Thus, within the framework of the study carried out, the authors propose an improved approach to the management of urban traffic flows, based on the regulation of the speed regime at the entrance to the city, taking into account the previously used characteristics - intensity and composition, and a previously unused indicator of weather conditions to ensure the operation of the existing technological equipment included into the ITS infrastructure.

To protect metal surfaces from the atmospheric corrosion the film-forming inhibitors are applied. This work presents the comparative analysis findings of the protective abilities of such corrosion inhibitors as preserving oil M-8V2 and composition on the basis of an oil-soluble inhibitor Telaz-M and M-8V2 oil. It is demonstrated that the oil composition, containing 20% of Telaz-M inhibitor, has high protective action against atmospheric corrosion for steel of grade St20 and alloy steel St12X18H10T. The protective action of the composition is explained by the formation on a steel plate’s surface of a film, which is an inverted emulsion (water in oil). This means that the drops of water, present on the metal surface, are encapsulated in the inhibitor’s oily solution, forming an emulsion. As a result, the metal contacts not with water, but with the oily solution of the inhibitor. The adding of Telaz-M increases the composition’s viscosity, which forms a thicker protective film on the surface of a steel plate.

A network for a large transport complex can consist of hundreds and thousands of jobs. Before creating a network, the people responsible for the schedule should think about how to highlight the most difficult parts of it. Therefore, the planning center developing the network schedule must study the designs of structures, establish the manufacturability of building structures, a list of the main technological equipment, the load of the organizations involved in the construction and determine the labor intensity of the main work. Therefore, the purpose of this article is to develop scientific and methodological approaches to the formation of management mechanisms for network planning of the transport system of the region.

The paper presents results of some analyzed statistical indicators of infant mortality and stillbirth in the North-Western Federal District of Russia. The following indicators are considered: availability of medical personnel and inpatient beds, morbidity of pregnant women, the number of abortions, as well as some socio-economic indicators. The negative correlation between infant mortality rate in the region and availability of obstetricians-gynecologists, pediatricians, neonatologists was revealed. Stillbirth rates in the region were found to be related to the provision of pregnant pathology beds, to the proportion of these beds in the total number of obstetric beds, to provision of the population with obstetricians and gynecologists. In addition, both factors are equally dependent on such index of work of women's family planning counseling services as the number of abortions per 100 live and stillbirths. A comparative analysis of the pregnant women morbidity, together with the investigated medical care provision in the region, emphasized the effective organization of the child protection and child delivery service activity in the North-Western Federal District, on the one hand. On the other hand, it determined that, in the search for a reserve of reducing fetal and infantile losses in North-Western Federal District, the priority area is a differentiated study of the pregnant women morbidity aimed at developing an appropriate comprehensive prevention program to reduce of the pregnant women morbidity.

The system of quality indicators used for public transportation is proposed by the authors. Additionally, the paper considers the necessity to develop an assessment ratio, which defines a competitiveness level among enterprises. To assess the activities of a transport operator, the authors proposed to apply a four-level system that will assess the quality of transportation: the level of service may be “excellent”, “good”, “satisfactory” and “unacceptable”.

The paper considers the ecological problems of water conditioning systems at heat power industry facilities. It is noted that the stable operation of water-heating equipment is provided with the quality of feed water. Various water-soluble salts, which can incrust the inner walls of boilers or pipelines, are removed from the natural water. For desalination of natural water the physical-chemical methods are mostly used. The by-product of desalination or chemical water-conditioning systems is the sludge waste. This work presents the results of using chemical water conditioning sludge from JSC Verofarm in the raw charge for wall ceramics production. The sludge is a finely-divided powder, the mineral composition of which is presented with calcium and magnesium carbonates, brucite and iron compounds, which make the sludge pink. It has been determined that the baking of sludge-containing ceramic samples at temperature 1000°C results in dissociation of calcium and magnesium carbonates with the formation of gaseous products H2O and CO2, which make the structure of ceramic materials porous. The presence of iron compounds in the raw charge promotes the formation of low-temperature silicate melt, which intensifies the baking process of ceramic samples. The optimal sludge content in the charge that doesn’t reduce the strength characteristics of wall ceramics is 10%. Such sludge content forms the liquid phase on the surface of the raw mix’s particles, which solidifies the forming pores. The increase of sludge content up to 20% intensifies gas generation; the amount of the formed liquid phase is not sufficient, which increases porosity and reduces the density and strength of ceramic materials. At that, the engobe layer is formed on the surface of the obtained wall ceramics samples. The wall ceramics products, obtained with the use of chemical water conditioning sludge, can be used as structural heat-insulation materials in making building envelopes or interior partitions.

Petroleum products belong to the most common man-made pollutants of surface watercourses, and sometimes even underground drinking water sources. They get to the environment at the extraction and transportation of oil and oil products, as well as at industrial disasters. The oil-contaminated sewage waters produce the general-toxic, embryotoxic and carcinogenic effect, and weaken the immune system. To purify wastewaters from petroleum products the most efficient and environmentally friendly is the sorption method. This paper considers using a carbon-containing material, obtained by thermal modification at 450°C of waste kieselguhr sludge from vegetable oil extraction industry, as petroleum sorbent. The designed sorbent is characterized with mesoporous structure, high hydrophobic properties and the presence of oxygen-containing functional groups – carboxyl, hydroxyl and lactone – on the carbon layer surface. Research has been carried out in purification of test water media from emulsified petroleum products in dynamic conditions with the use of the designed sorbent. The number of passed sorption volumes to the «breakthrough» and the full saturation of the sorbent with oil products were determined. The calculated dynamic exchange capacity of the sorbent for petroleum products is 2.9 mg/g, the total exchange capacity – 8.4 mg/g. The limiting stage of petroleum products sorption process kinetics with the carbon-containing sorption material in the studied conditions is diffusion inside the sorbent grains.

The article deals with the design of decision support systems in the transport industry based on fuzzy situational networks, which are parameterized by a set of states and transitions between them. The proposed model is represented as a fuzzy hierarchical situational-event network. A mechanism for the dynamic formation of fuzzy situational networks has been developed. The obtained optimal estimates of control decisions that come out of the network nodes represent the basic mechanism for generating transition estimates. In the general case, the use of situational networks as a basic technology for creating decision support systems presupposes the existence of a knowledge base with a structure corresponding to the description of knowledge in the formed model of a fuzzy situational network.

Every year, tens of thousands of road traffic accidents occur on the territory of Russia, characterized by different accident rates. Some of the most common are road traffic accidents, in the place of which violations of the mandatory requirements for the operational state of highways and railway crossings have been recorded under the conditions of ensuring road safety. The condition of the asphalt concrete road surface affects the grip performance of the vehicle with the road. It is necessary to study the statistics of road traffic accidents in the constituent entities of the Russian Federation located in different road and climatic zones in order to determine the dependence and the degree of influence of the state of the road surface on the number of accidents occurring.

One of the urgent tasks is to determine the composition of the bus fleet to serve each route. At the same time, it is necessary to be able to vary the type and number of buses that have different technical characteristics, in this regard, in the framework of the study, the issues of optimizing bus movement modes on city routes were considered. Basically, on the city route network, buses stop at all stopping points. However, quite often there is a situation when there is a sufficiently large unevenness of passenger traffic at various stopping points. In this regard, design schemes for analyzing the effectiveness of combined and shortened routes are proposed. Key relationships include empirical estimates of passenger flows. The parameters of the models are the volume of the bus fleet, the irregular production of buses, the probability of a denied boarding at individual stopping points.

Among the multitude of vehicle suspension assemblies, the ball joint is one of the most important bearing assemblies, the operability of which directly depends on the operating conditions. Ball joints are used to connect the suspension and steering components and are kinematic interfaces that have three angular degrees of freedom when moving the working elements (levers). The reliability of the hinges has a significant impact on the safety of the car. In most cases, the ball joint is an indiscriminate node, which makes it difficult to determine the technical condition in a car service center. One of the methods of diagnosing are laboratory bench examinations of ball joints. To obtain reliable information about the wear of ball joints and the development of a technique for determining their technical condition in the conditions of an auto service company, a laboratory bench research area is needed. The completed research aimed at developing methods, tools and algorithms for determining the technical state of ball joints in the conditions of an auto service company. As a result of the research, the author’s team developed a vibration method for determining the technical state of ball joints and a mathematical model for changing the technical condition of the ball joint of the front suspension of the MacPherson type of a car, in bench tests.

The article presents the research findings concerning the usage of carbon-containing water treatment sludge of test solutions, containing emulsified oil products, in raw charge for wall ceramics production. For removing oil products kieselghur sludge was used, generated at the refined vegetable oil production at winterization stage (removing waxes and waxlike substances), thermally modified at temperature 450°C. Water treatment sludge is characterized with organo-mineral composition. It was determined that baking ceramic samples with water treatment sludge at temperature 950°C causes the oxidation of oil products with the formation of gaseous products CO, H2O and CO2, which makes ceramic materials’ structure porous, which in its turn reduces their density and improves their heating-performance characteristics. The presence of organic substances in the charge for ceramic materials creates favorable thermodynamic conditions for iron oxides reducing reactions, which contribute to the formation of low-temperature silicate melt and intensify the samples’ baking process. The wall ceramics products, obtained with the use of water treatment sludge, can be used as construction material and heat-insulating material in enclosing structures and at internal partitions installation.

In order to assess fetoinfantile losses in the North-West of Russia, the official and operational data of the Federal State Statistics Service and the Central Research Institute of Health Organization and Informatization of the Ministry of Health of the Russian Federation for 2010-2016 were studied. It is established that the indicator of fetoinfantile losses in the North-West region is much lower than fetoinfantile losses in the whole Russia. The evaluation of the dynamic coefficient of fetoinfantile losses showed a decrease for the years 2012-2016, as in Russia in general and in the North-West region. The structure of fetoinfantile losses in 2016 in the Russian Federation was significantly dominated by the share of infant mortality, and in the North-West Federal district – stillbirth. In the structure of fetoinfantile losses attributable to the period of infant mortality, the largest share accounted for mortality in the early neonatal period. Reduction of fetoinfantile losses due to infant mortality has been achieved mainly due to early neonatal mortality. Level of fetoinfantile losses attributable to the period of early neonatal deaths had a direct correlation with mortality level of children with a body weight of 1000 grams or more in the departments of pathology of newborns. The frequency of deaths in children weighing 1000 grams or more in the neonatal pathology departments of the North-West Federal district is significantly higher than in the whole Russia. The survival rate of children with extremely low birth weight from the total number of children born with a body weight of 500-999 grams in the North-Western region exceeded the figure for the whole Russia by 48.32%.
