Problematic issues of management of the Federal fire service and other types of fire protection
Authors:   All-Russian Research Institute of Fire Protection of EMERCOM of Russia, Vlasov Konstantin Sergeevich
Published: December 2022

Introduction. The activities of fire and rescue units can be conditionally divided into extinguishing a large number of ordinary fires and single large fires. Considering these categories of fires from the point of view of economic efficiency and ensuring the level of combat readiness of fire departments, a decision tree model is proposed to identify the most promising ways to develop the organization. The functioning of fire and rescue units within the garrison is studied from the standpoint of assessing the long-term cyclical development of the organization, taking into account various external and internal factors. The tasks of the research are to identify problematic issues of management of fire and rescue units of the Federal Fire Service and fire protection units of other types stationed on the territory of the fire and rescue garrison, taking into account the scale of fires and evaluating the effectiveness of the organization of activities. Methods. Big Data technologies based on the methods of mathematical statistics of the software modules Panda and NumPy of the high-level programming language Python 3 are applied. The "Decision Tree" method implemented by means of the sklearn Python module and the packages CHAID and rpart of the programming language for statistical data processing R is used. Results and discussion. The frequency of occurrence of large fires, when the involvement of almost all available forces and means of the fire and rescue garrison is required, is about one case for an interval of 4-5 years. The number of ordinary fires during the same time is approximately 100-130 thousand cases. Such a ratio of ordinary and large fires is a source of significant contradiction and leads to a number of problematic issues related to the organization of management of Federal Fire Service units, as well as units of other types of fire protection. To study the proposed issues in the context of comparing the categories of economic efficiency and the level of combat readiness of units, the "decision tree" method was applied. Conclusions. The analysis of the results of the functioning of the fire and rescue garrison at the limit of permissible possibilities arising in the process of eliminating a large fire shows that all the management structures of the garrison are affected and, based on the results of the study of the actions of the garrison units, objective prerequisites for a leap (qualitative) reform of the management system can be formed. Keywords: large fire, operational activity, busy time, mobile fire and rescue equipment, fire extinguishing devices, histogram, decision tree.

Introduction. The results of a series of experiments on the interaction of fire extinguishing foam with various hydrocarbons are described, which make it possible to understand the processes that affect the extinguishing efficiency. Goals and objectives. The purpose of this work was to explain self-emulsification during mass transfer as a possible dominant factor in the process of contact destruction of fire-extinguishing foam by hydrocarbons. For this, the following tasks were set: - to experimentally establish the possibility of self-emulsification during mass transfer in contact of foaming agent solutions with hydrocarbons; - to show the relationship between the stability of the foam and the stability of the emulsion formed in the foam films; - to establish the effect of foam parameters (multiplicity) on the possibility of stabilization (or destruction) of foams under the action of the resulting emulsion. Research methods. The main research method in this work was to observe the stability of the foam on the surface of hydrocarbons at different temperatures. Results and discussion. The paper presents the results of experimental studies showing that the contact of solutions of the investigated foaming agents with hydrocarbons leads to the spontaneous appearance of an emulsion. In the case of using aromatic hydrocarbons, this process is more intensive than for saturated ones. For solutions of a foaming agent in the form of a thin film, the process of self-emulsification during mass transfer is significantly accelerated and can take place at room temperature. A stable emulsion, introduced into the foam, stabilizes it, and an unstable one destroys it. Low expansion foam is usually stabilized in contact with hydrocarbon. Medium expansion foam is destroyed even under the condition of thermodynamic stability of foam films. Conclusion. The experimental data obtained made it possible to propose a mechanism for the contact interaction of foam with a hydrocarbon, according to which a more stable foam on the surface of a hydrocarbon can be obtained by a foaming agent, which, in addition to foaming properties, is a good emulsifier. Keywords: fire extinguishing foam, hydrocarbon, oil product, contact destruction, self-emulsification during mass transfer.

Authors:   Academy of State Fire Service of EMERCOM of Russia, Shvyrkov Sergey Alexandrovich
Published: December 2022

Introduction. The most widely used for the storage of oil and petroleum products at industrial enterprises both in Russia and abroad, were vertical steel cylindrical tanks). However, despite the significant world experience in the design, construction and operation of vertical steel cylindrical tanks, from time to time their failures (destruction) occur, leading to negative consequences. Interacting with normative earthen landslides or enclosing walls, the resulting powerful hydrodynamic flow of liquid flows through them, spilling over a large area, involving in the incident nearby tanks, buildings, structures, pipelines, which leads to the cascading development of the accident, significant material damage, often to injuries and loss of life. Thus, a more detailed consideration of the effectiveness of existing ways to minimize the negative consequences of tanks destruction, as well as problematic issues of some promising methods on the topic under consideration, seems relevant. Goals and objectives. Identify the most effective ways to minimize the negative consequences of possible destruction of vertical steel cylindrical tanks. Analyze the consequences of characteristic accidents of vertical steel cylindrical tanks at production facilities. To propose a classification of methods on the basis of preventing or localizing the breakthrough wave formed during the destruction of vertical steel cylindrical tanks. To consider the problematic issues of promising ways to localize flammable liquid. Methods. In the process of developing a number of ways to minimize the negative consequences of accidents on vertical steel cylindrical tanks, methods of similarity theory and laboratory modeling, physical experiment, observation, comparison, finding empirical dependencies based on mathematical processing of experimental data, description, generalization were used. Results and their discussion. It has been established that the most effective way is to eliminate the dangerous factor (breakthrough wave) through the use of underground or horizontal tanks. Effective ways to localize the flow of liquid include the arrangement of an enclosing wall with a wave reflective visor or a protective wall additional to the normative fence. A promising method includes the construction of tanks of the "glass in a glass" type. Conclusion. The effectiveness of the considered methods should be taken into account, first of all, by the owners of hazardous production facilities, specialists of design organizations and supervisory authorities to find optimal solutions for the safe operation of tanks, including, if necessary, their placement in settlements, near water areas and federal highways. Keywords: tank, destruction, breakthrough wave, earthen collapse, enclosing wall, enclosing wall with a wave reflective visor, additional protective wall, "glass in a glass" tank.

Based on remote sensing data, the authors consider the features of the formation and use of green spaces in the city of Nadym (Yamalo-Nenets Autonomous Area). They give a detailed assessment of the availability of green infrastructure for the inhabitants of Nadym based on a comparison of the spatial distribution of vegetation and the urban population. During the construction of the city, there was a dramatic reduction in the area of vegetation cover, which reached its maximum during active construction in the 1980s. After the completion of the main construction stage and until now, there has been a steady increase in the share of vegetation, which is explained by active landscaping activities against the backdrop of climate softening. The authors have find out that while maintaining the high availability of open green spaces within the city, the main lack of vegetation is observed within the residential development of microdistricts. The methodology for the integrated use of medium and ultra-high resolution space images, UAV surveys, detailed mapping of residential buildings and field geobotanical descriptions tested during the study can be used in a detailed analysis of the state of the green infrastructure of other cities in the north of Western Siberia. In general, the assessment of the green infrastructure availability in the Arctic cities is of great importance for urban planning, allowing to fully take into account the regional environmental needs of local residents, in the context of the heterogeneity of their distribution.

Authors: Terpugov A. E. , Titov A. K.
Published: December 2022

The modern development of the energy industry, as well as other sectors of the economy, is impossible without an environmentally oriented approach. Therefore, the green energy direction has received a fairly wide development in the world in the last decade. This energy has less negative impact on the environment due to the fact that there is no need to use fossil fuels. Due to the significant reserves of these resources, the introduction of renewable sources in Russia is slower compared to the leading countries in the field of green energy generation. Attempts to close the gap in this direction appeared only in recent years. The article is devoted to the assessment of the environmental agenda in the Russian power industry. In particular, the authors consider the issues of reducing the consumption of resources for electricity generation, as well as give an overview of the distribution of renewable energy in Russia as a whole. The scientific novelty lies in the consideration of a number of technical and economic parameters of the power generating industry operation, as well as in the construction of time series based on the most important statistical indicators of the power industry. Their visual representation is based on the use of tabular and graphical methods of information processing. In addition, a review of the industry companies reporting in recent years regarding the implementation of ESG concepts was made.

Authors: Serdobintsev D. V. , Aleshina E. A.
Published: December 2022

Currently, the Russian economy is undergoing active processes of digital transformation and system integration in all areas of production and economic activity. At the same time, the agro-industrial complex and agriculture lag behind the leading industries in terms of the level of digitalisation. This opens up large-scale prospects for the implementation of information technology projects, but also dictates the need to introduce additional measures to accelerate the development and implementation of digital technologies. The growing popularity of system integration is explained by a number of advantages: reducing the time for information exchange, decision-making and goods circulation, eliminating duplication of functions and the overall economic effect for each of the participants due to a wider and more comprehensive integration of computer systems. To support such initiatives, the study proposes a mechanism for the system integration of the resource subsystem of agricultural, processing and marketing enterprises in the region using a theoretical and methodological basis. Achieving the highest level of system integration is expected through the integration of information systems on a platform framework, as well as the addition of digital services of financial operators with the connection of economic entities of the agro-industrial complex. The developed mechanism reflects the algorithm of strategically significant events with a target orientation towards expanding the scale of system integration of enterprises in the agro-industrial complex. Its implementation will provide an opportunity for global planning in industries and provision of recommendations to market participants, including those based on artificial intelligence technologies.

Published: December 2022

The article explores the theoretical approaches of Russian and foreign regionalists to the region, resources, potential, efficiency in the use of resource potential concepts definition. The authors note the versatility of the efficiency concept in the context of various aspects of the national economy. They conclude that the efficiency of using the region resource potential is understood as the rational use of the resources under management to achieve the goals set, to meet the existing demand. Further, it is determined that the structure of the resource potential remains a subject of discussion in the scientific community, there is no consensus on the constituent elements of its structure. The authors emphasize that the systematization of the structural elements of the resource potential of the region and approaches to its definition is especially relevant for the Russian economy, as it will allow determining the directions for using the resource component of the country’s economy. The economic space of most regions of the Russian Federation is characterized by uneven economic development and its weak diversification, at the same time they have significant natural resource potential. To ensure the competitiveness of resource-oriented regions in the national and world markets, to create import substitution programs and ensure the innovative content of their economy, it is necessary to transform the structure of the economy in favor of higher technological structures.

Aim. To assess the effect of pandemic COVID-19 on the course of STEMI patients of the Regional Vascular Center in 2020, compared with the previous year.
Materials and methods. Patients with acute coronary syndrome and, in particular, STEMI hospitalized at Regional Vascular Center in 2019 and 2020.
Results. In 2019, 981 patients with STEMI were admitted; in 2020 728 patients. The baseline clinical and demographic patients characteristics did not differ significantly. In 2020, the number of pneumonia has doubled, the number of mechanical ventilator support has increased by 20%; sepsis was diagnosed 5 times more often. However, patients in 2020 were less likely to develop delirium, minor and major bleeding. There were more patients admitted in the 1st day of the disease, and they were more frequently performed both primary angioplasty and angioplasty in general. Patients with STEMI in 2020 had more frequently registered pulmonary edema, cardiogenic shock and re-infarction. Lethality in the group of patients without angioplasty tended to be higher in 2020 compared with the previous year. None of 30 patients with COVID-19 died in our department, they were timely transferred either to COVID-hospital or to outpatient follow-up care. When analyzing various parameters during the spring and autumn periods, which were the peak periods for pneumonias in 2020, only mortality had a clear upward trend.
Conclusion. The patient portrait of myocardial infarction in 2020 was dominated by pneumonia, sepsis, and re-infarction compared with the previous year. An upward trend in mortality was detected in those without angioplasty and those hospitalized in the spring and autumn wave of COVID-19. We believe that there are hidden mechanisms of pandemic effect on mortality in STEMI.

Background. Tuberculosis is a serious medical and social problem that does not lose its importance, despite all the advances in pharmacology and surgery. Diagnosis of urogenital tuberculosis (UGTB), as a rule, is delayed due to low index of suspicion to tuberculosis and the absence of pathognomonic symptoms.
Aim. Determining the change in the ratio of clinical forms of renal tuberculosis from 1999 to 2020.
Materials and methods. A retrospective cohort comparative non-interventional study on the spectrum of the incidence of extrapulmonary tuberculosis (EPTB) was carried out. Among all 13852 extrapulmonary tuberculosis patients which were diagnosed from 1999 to 2020, patients with renal tuberculosis were selected, and the spectrum of their clinical forms in three periods was analyzed: 1st period 19992004 (1155 patients), second period 20052014 (2657 patients), and the third period 20152020 (671 patients). The clinical features of nephrotuberculosis in 88 patients was also estimated.
Results. Over the 20 years of the analyzed period, the number of patients with UGTB decreased by 80.6%; for the year of the COVID-19 pandemic, this figure fell by another third. In the first period, destructive complicated forms of nephrotuberculosis prevailed (922 patients 79.8%), while the so-called "minor forms" were diagnosed in 233 patients (20.2%). In the second period, the situation was statistically significantly more favorable: the proportion of destructive and complicated forms of renal tuberculosis decreased to 43.8% (1124 patients), "small forms" were diagnosed in 1443 patients (56.2%). In the third period, destructive and complicated forms of nephrotuberculosis were diagnosed in 531 patients (77.6%), and the proportion of "small forms" in comparison with the previous period decreased by half, to 22.4%. Analysis of the clinical features of renal tuberculosis, depending on the prevalence of the destruction, showed that an asymptomatic course is possible, and pain, dysuria, intoxication and renal colic are present with different frequencies, and the clinical picture of tuberculosis of the renal parenchyma differs significantly from the clinical picture of tuberculous papillitis, cavernous nephrotuberculosis and symptoms of renal tuberculosis as whole.
Conclusion. Currently, there is no screening on urogenital tuberculosis at all. Patients are diagnosed by referral, with a long history, after receiving multiple courses of antibacterial treatment; mainly through the pathomorphological examination of the operating material. Thus, a sharp decrease in the proportion of UGTB patients does not mean the disappearance of tuberculosis of this localization, but only states the tragic defects in timely diagnosis and low index of suspicion of medical doctors in relation to UGTB.
Liver disease during the pandemic of COVID-19 infection: prediction of the course and tactics of management: A review

Published: December 2022

The hepatic consequences of SARS-CoV-2 infection are now recognized as an important component of CoronaVIrus Disease 2019 (COVID-19). This aspect is most clinically relevant in patients with pre-existing chronic liver disease (CKD), who are at extremely high risk of severe COVID-19 and death. Risk factors for severe CKD, especially in people with liver cirrhosis and non-alcoholic fatty liver disease, are the direct and indirect cytotoxic effects of coronavirus against the background of systemic inflammation, blood clotting disorders and immune dysfunction. The severe negative impact of the pandemic in the presence of CKD and the difficulties of patient relationships contribute to the progressive increase in the global burden of liver disease on the health system.

Aim. The role of cyclooxygenases (COX-1 and/or COX-2), transcription nuclear factor NF-B, anti-inflammatory cytokines TGF1b, IL-4, IL-10 and pro-inflammatory cytokines IL-1, IL-6 were studied to substantiate the expediency of antiviral agent enisamium iodide (Nobazit) using to regulate key inflammatory components in acute respiratory infections, IL-8, TNF-alpha in the realization of the pharmacological activity of this drug.
Materials and methods. Gene expression was determined by real-time RT-PCR, the concentration of interleukins was determined by ELISA, and the viability of peripheral blood mononuclear cells (PBMC) was assessed by the MTT spectrophotometric method. The chemiluminescence method was used to assess PBMC oxidant activity.
Results. Enisamium iodide (10 M) reduced mRNA levels of COX-1, COX-2, NF-B, TGF1b, IL-1, IL-6 in stimulated PBMC of healthy donors by an average of 48% (p0.05). At 5 times higher concentration, 50 M, enisamium iodide suppressed the expression of these genes by an average of 43% (p0.05). At a concentration of 100 M, enisamium iodide reduced the expression of COX-2, TGF1b, IL-1, IL-6 by an average of 47% (p0.05). At a concentration of 10 M, enisamium iodide stimulated the secretion of IL-10 by mononuclear cells by 1.2 times, p0.05. The tested drug at a concentration of 50 M did not affected on the concentration of IL-1, IL-4, IL-8 and TNF-alpha, but significantly stimulated the production of IL-10 by 1.5 times, p0.05. The chemiluminescence method revealed that enisamium iodide in the entire concentration range (10100 M) does not reduce the viability of macrophages, but inhibits their oxidative activity (maximum value of CL intensity) by an average of 55% (p0.05).
Conclusion. The anti-inflammatory effect of enisamium iodide at a concentration of 10 M may be associated with inhibition of the expression of COX-1, 2, NF-B, IL-1, IL-6, TGF1b and an increase in the expression and production of IL-10. An additional contribution to the anti-inflammatory activity of enisamium iodide is made by its antioxidant and antiradical activity. The absence of the effect of enisamium iodide (10100 M) on the viability of PBMC indicates its safety for the cells of the immune system and the expediency of using it to suppress inflammatory reactions in acute respiratory infections, restore the quality of life of patients and the possibility of using Nobazit as an effective agent for treatment of these infections of various etiologies.
