The new coronavirus infection has posed a major public health challenge around the world, but new data on the disease raises more questions than answers. The lack of optimal therapy is a significant problem. The article examines the molecular mechanisms of SARS-CoV-2 infection and the pathogenesis of COVID-19, special attention is paid to features of pathological processes and immune responses in children. COVID-19 leads to a wide diversity of negative outcomes, many of which can persist for at least months. Many of the consequences have yet to be identified. SARS-CoV-2 may provoke autoimmune reactions. Reinfection, herd immunity, vaccines and other prevention measures are also discussed in this review.

The review presents data on the features of COVID-19 infection course in children of different ages. It has been shown that children carry the disease much easier than adults. However, the younger the child, the more often he has a severe infection. Infants and newborns suffer the most severe COVID-19 disease. In the future, the older the child (up to 18 years old), the easier his illness progresses, less often severe pneumonia accompanied by acute respiratory respiratory syndrome (ARDS) occurs and there is practically no multiple organ. The most common symptoms in affected children with COVID-19 are short-term fever, easy fatigue, myalgia, nasal congestion, runny nose, sneezing, sore throat, headache, and dizziness. Less common is nausea, vomiting, abdominal pain, diarrhea. In children, in contrast to adults, neutrophilia, thrombocytopenia, lymphocytopenia occur less often, the content of pro-inflammatory cytokines increases moderately, and only in isolated cases does the state of cytokine storm occur. In children, it is extremely rare for the D-dimer to reach high numbers, indicating the presence of intense intravascular blood coagulation. Therapy for children with COVID-19 should be based on the severity and age of the child. A significant role in the fight against COVID-19 is assigned to immunocorrective drugs (INF-γ, tocilizumab, azithromycin, doxycycline, etc.) and antiviral drugs (favipiravir, etc.) play a significant role in the fight against COVID-19. We believe that thymalin, which has proven itself well in pneumonia and various infectious diseases in both adults and children.

For many decades, researchers have been interested in the problem of the relationship between cough and gastroesophageal reflux (GER) and gastroesophageal reflux disease (GERD). The question has not only theoretical, but also practical significance, since it determines the diagnostic and therapeutic, both for coughing and for GER, while uniting under their «banners» specialists of various profiles: physicians, pediatricians, gastroenterologists, pulmonologists and others. This article presents and discusses the data of domestic and international publications on this issue and, based on current knowledge, the concept of the relationship between GER, GERD and cough, including bronchoobstructive syndrome in bronchial asthma, is proposed, as well as recommendations for practical work of doctors in this clinical situation. Based on the available data, it can be argued that the relationship between GER (GERD) and cough is obvious, but many details of this interaction remain poorly understood. It should be noted the important role played by a hiatal hernia (HH) both in the development of GER and the cough associated with it. Children with chronic cough that do not respond to basic therapy are shown to be examined in order to identify the possible effect of GER on its formation. In this regard, it is important to identify HH in order to determine the tactics of patient management and resolve the issue of its surgical correction. On the other hand, patients with GERD are shown at least a minimal examination to clarify the state of the respiratory system, even in the absence of obvious respiratory symptoms.

Objective of the research: to assess the physicians' coherence on the prevention of viral hepatitis C (HCV) in children at the stages of medical care in maternity and child protection service (MCPS). Materials and methods: pilot study, coherence was assessed according to the questionnaire data of 4 groups of MCPS specialists: therapeutists (n=73), obstetricians-gynecologists (n=47), neonatologists (n=24) and pediatricians (n=87) using the Cohen's Kappa (κ). Results of the physicians’ coherence on the prevention of HCV did not reach the degree of good (p<0,05) and excellent (p<0,05) and depended on the semantic content of the question and the physicians’ specialty. Therapists had the worst agreement in the answers to questions reflecting medical activity, obstetriciansgynecologists – in terms of special knowledge about HCV, neonatologists – in their answers to questions on the organization of medical care for patients with HCV and patients from HCV-risk groups. Pediatricians, as well as therapeutists, had the greatest differences in answers to questions reflecting medical activity and, similarly to neonatologists, inconsistencies on organizational issues. Conclusions: it is necessary to develop and implement measures in practical healthcare that ensure consistency and continuity of physicians in the prevention HCV in children at each of the stages of medical care in MCPS.

A year ago, the world heard about an outbreak of a new severe coronavirus infection in China, which later, after its rapid spread across the globe, WHO defined as a pandemic. Pediatricians, of course, expected the worst-case scenario and mass illness of the most vulnerable patients – children and people of older age groups with a new infectious disease. From the immunological point of view, everything is obvious – the new pathogen is most dangerous for those who have not yet formed a defense against it, or for those with weakened defense. But it quickly became clear that, unlike, for example, a flu pandemic, there is an unexpected situation when adults, including elderly and senile patients, become seriously ill and die, and children remain practically outside the spread of the infectious process. During a year of living «in a new reality», not only physicians, but all of humanity learned to respond to a new infectious challenge, empirically looking for possible therapeutic or diagnostic interventions and at the same time trying to plan and implement scientific research that would help shed light on the questions posed. For the first time, the international medical community united to perform serious clinical trials of drugs that were proposed for the treatment or prevention of COVID-19. As a result of actions of scientists and clinicians around the world, answers to some questions were obtained, however, most of the information on the impact of the new coronavirus on the human body, including children, is still unavailable to medical practitioners. The review presents latest data on the causative agent of the new coronavirus infection, its effect on the body of children and adults, describes peculiarities of immune response to the new virus, and outlines basic principles of managing such patients in real clinical practice.

Synthesis of a Fuzzy Logic Model Rule Base through Supervised Learning
Authors:   NRU MPEI, Novikov Viktor N.
Published: November 2020

Intelligent information systems are at present actively incorporated in almost all industry fields. Out of many approaches to construction of such systems, the following two methods are worthy of noting: a method involving the use of expert knowledge, which include, in particular, fuzzy modeling), and a method of supervised machine learning, which estimate this knowledge from the available data marked depending on the objectresponse pairs. Each of these methods has its essential advantages and drawbacks. A combined use of both the approaches for solving the classification case is given. The proposed method for training a fuzzy classifier includes fuzzification of the input features of objects, shaping of logical rule conditions for the fuzzy model rule base, and selection of the most typical rule conclusions for filling the relational matrix. The terms of input features and their membership functions behave as the fuzzy model hyperparameters. As an example, the case of binary classification in a two-dimensional coordinate space with a nonlinear distribution of classes is considered. The sets of terms and membership functions ensuring high-quality classification on the training and test data have been found for each of the coordinates. The fuzzy classifier trained using the proposed method is able to solve a number of binary and multi-class classification cases. It can be applied in a situation involving difficulties in specifying an a priori rule base, and supervised learning is allowed to be used as a solution. Since the approach has logical rules at its heart, transparency of the model is ensured, and explanations to the results yielded by the model can be done.

Published: November 2020

The purpose of the study is to construct mathematical models of electric energy and power consumption for six price categories in an organizational and technical system and to develop an algorithm based on these models that will enable the consumer to select the most profitable cost of electricity. The system, which was regarded as an integral complex of interacting objects, was analyzed from the viewpoint of a systematic approach. Scientific data were analyzed proceeding from the principles of system consistency, structuring, integrity, hierarchy and multiplicity. A structural-and-functional approach, based on which elements (subsystems), and relationships between them can be considered within a single organizational and technical system, was used as the research method. The current state was studied; the consumption of electricity by an organizational and technical system was predicted based on the source data; the mathematical models of electric energy and power were constructed for six price categories, and a price category selection algorithm was developed, using which the most financially profitable price category can be found. An independent experimental verification of the price category selection algorithm was carried out, which has shown that owing to its application, the cost item “payment of consumed electric energy” for the facility has decreased by 9%. The experiment has shown that the developed mathematical models can be applied in practice, and that the use of the electric energy price category selection algorithm allows economic gains to be obtained. The accomplished study has yielded results based on which the consumers located in the Russian Federation territory can select the most financially profitable price category and cost of electric energy.

Published: November 2020

A method for solving the problem of classifying short-text messages in the form of sentences of customers uttered in talking via the telephone line of organizations is considered. To solve this problem, a classifier was developed, which is based on using a combination of two methods: a description of the subject area in the form of a hierarchy of entities and plausible reasoning based on the case-based reasoning approach, which is actively used in artificial intelligence systems. In solving various problems of artificial intelligence-based analysis of data, these methods have shown a high degree of efficiency, scalability, and independence from data structure. As part of using the case-based reasoning approach in the classifier, it is proposed to modify the TF-IDF (Term Frequency - Inverse Document Frequency) measure of assessing the text content taking into account known information about the distribution of documents by topics. The proposed modification makes it possible to improve the classification quality in comparison with classical measures, since it takes into account the information about the distribution of words not only in a separate document or topic, but in the entire database of cases. Experimental results are presented that confirm the effectiveness of the proposed metric and the developed classifier as applied to classification of customer sentences and providing them with the necessary information depending on the classification result. The developed text classification service prototype is used as part of the voice interaction module with the user in the objective of robotizing the telephone call routing system and making a shift from interaction between the user and system by means of buttons to their interaction through voice.

Published: November 2020

The aim of the study is to evaluate the extent to which the generating capacities of hydroelectric power plants (HPPs) are underutilized during their joint operation with thermal power plants (TPPs) in a grid under high water conditions. The data on constraints imposed on the operation of power plants in different periods of time for determining their operation intervals were studied based on reported information on the market operation modes for a day ahead. The analysis was carried out for joint operation of HPPs and TPPs in years characterized by different abundance of water resources. Data for the Interconnected Power System of Siberia and two typical periods, namely, an average working day in January and an average working day in June were taken as an analysis example. For each of the considered HPPs, their initial participation was made in the grid load curve: in the load curve base part according to the above-mentioned base part and the HPP monthly average power, and in the load curve peak part according to monthly average and working power (minus their operation in the load curve base part). The participation of the HPPs was determined taking into account the technical and technological minimums of TPP operation. The procedure of determining the participation of power plants is iterative in nature and uses the method of golden section for selecting the parameters characterizing the power plant participation in the load curve and the power capacity margin. It follows from the obtained results that in January, the limitations relating to the TPP operation mode impose no constraints on the operation of HPPs. However, in the June load curve, in which the influence of water abundance on the HPP operation mode is much more significant due to the HPP operational requirements, the HPSs cannot operate at their full capacity; that is, the extent to which the HPP capacity is underutilized depends on the water abundance in a year. By using the developed algorithm, it is possible to estimate the amount of HPP generating capacity underutilized in an interconnected power system. The underutilized power generation capacity of the Angara-Yenisei HPP chain in the Interconnected Power System of Siberia can be used for generating and transmitting power to the European part of the UES of Russia, e.g, to compensate the insufficient output of HPPs in the Volga-Kama chain during low water periods.
Promising Osmotic and Hybrid Electrochemical Power Plants
Authors:   NRU MPEI, Tsgoev Ruslan S.
Published: November 2020

A range of energy technologies ultimately aimed at obtaining electric energy is considered. Proceeding from the list of considered sources, it is possible to analyze their different combinations for achieving better energy efficiency of new complexes. A systematic list of 21 currently known traditional, non-traditional, and renewable energy sources is compiled. Each of them taken individually has an efficiency not exceeding 50%, except for some types of fuel cell based power facilities. Block diagrams of energy flow conversion stages are proposed for the considered kinds of sources. Obviously, if some or other chain does not contain certain blocks in comparison with the first classical chain of thermal engine thermodynamic cycles, this means that the missing energy conversion stages of are either implemented covertly, or proceed in the environment. As an example, two promising sources are considered: an osmotic hydroelectric power plant and a hybrid power plant (HybPP) based on high-temperature fuel cells with solid oxide electrolyte and a gas turbine unit. In fact, an osmotic hydroelectric power plant takes the solar energy spent for evaporation from sea surfaces in the form of the osmotic pressure phenomenon energy under the conditions of one-way diffusion of fresh river water (a solvent) molecules through a semi-permeable membrane towards salt sea water (a solution). An osmotic HPP is a combination of a reservoir with semi-permeable membranes and an HPP. The former is characterized by the expected high specific power up to 12 kW per square meter of semi-permeable membrane area, and the latter is characterized by the highest efficiency among all types of electric power sources and by the high achieved specific power up to 2-3 kW per square meter of solid oxide electrolyte surface area.
The Influence of Climatic Factors on the Distribution of Noise from Gas Distribution Stations
Authors:   NRU MPEI, Tupov Vladimir B. , Skvortsov Vitaliy S. ,   NRU «MPEI»
Published: November 2020

The article discusses the influence of regional climatic factors on the propagation of noise from gas distribution stations (GDS), which are intense sources of noise for the surrounding area, and suggests a procedure for determining the required extent of noise reduction. GDSs produce high-frequency noise with the maximum values at the octave band central frequencies equal to 1000, 2000, 4000, and 8000 Hz. It is shown that climatic factors have quite a significant influence on the propagation of high-frequency noise from gas distribution stations precisely at the octave band central frequencies equal to 1000, 2000, 4000, 8000 Hz. The sound pressure levels may vary very significantly during a year depending on the region due to sound attenuation factors in the atmosphere. The climatic data for 210 cities of Russia were analyzed. The data on variation of climatic conditions during a year for these cities are taken from the Code SP 131.13330.2012. These changes for the octave band central frequency equal to 4000 Hz can make from the minimum range of 5.61 dB in the Sochi city region to the maximum range of 19.35 dB in the Chita city region; for the octave band central frequency equal to 8000 Hz they can make from the minimum range of 14.58 dB in the Elton city region to the maximum range of 48.63 dB in the Chita city region. The difference between the range smallest and largest values increases with the octave band central frequency. Thus, for the octave band central frequency equal to 1000 Hz this difference is 3 dB, whereas for the octave band central frequency equal to 8000 Hz this difference is 34 dB. The influence of climatic factors on the required extent of noise reduction from a GDS depends significantly on the region and can make tens of decibels for a combined heat and power plant with a 300-m wide sanitary protection zone. Therefore, for elaborating the necessary measures for reducing noise from a GDS, it is necessary to take into account the minimum atmospheric sound absorption coefficient for a particular region.

The relative concentration of deuterium implanted in beryllium is determined on the basis of the elastic peak electron spectroscopy. To consistently determine the energy spectra of reflected electrons, the method of partial intensities is used, which is based on solving the boundary problem for the transport equation by the invariant imbedding method. The differential inelastic scattering cross sections are reconstructed using a fitting procedure based on the multiple solution of the direct problem with fitting parameters. High efficiency of the fitting procedure is achieved through constructing a numerical procedure for solving the equations for partial intensities, a technique that combines accuracy and extremely high computation speed. Differential cross sections of inelastic scattering are obtained both for the near-surface area and for a homogeneous area distant from the surface. The differential inelastic scattering cross sections have been calculated for both pure beryllium and beryllium samples subjected to deuterium implantation. The relative concentrations of deuterium in beryllium have been determined, the values of which are equal to 0.12±0.03 (for a dose of 55 deuterium atoms per square Angstrom) and 0.15±0.03 (for a dose of 201 deuterium atoms per square Angstrom). The obtained results indicate that the developed method has made it possible to achieve an order of magnitude better sensitivity of determining the relative concentrations of hydrogen isotopes in compounds in comparison with the previously existing methods.

Este artículo busca poner en valor la actividad del Departamento Topográfico como productor y recopilador del saber territorial durante el siglo XIX en la provincia de Buenos Aires. Buscamos demostrar que, desde su establecimiento en 1824 y con diferentes nombres, el Departamento pasa de ser una institución central para la conformación del Estado, concentrando múltiples funciones, a ser una sección técnica dentro una estructura más amplia como fue el Ministerio de Obras Públicas de la Provincia de Buenos Aires. Mediante el análisis de esta repartición, buscamos demostrar la íntima relación que existía entre la producción de mapas topográficos y catastro durante el siglo XIX, cuando los medios y las técnicas disponibles obligaron a la unión de esfuerzos. Ello fue posible gracias a la estandarización de los trabajos, a la redacción de instrucciones, en suma, a una normalización de las prácticas que tiene su origen en el estado rivadaviano y se prolonga durante todo el siglo.
Trabajos topográficos. Un acercamiento preliminar al armado del caleidoscopio topográfico nacional
Authors: Amarilla Federico
Published: November 2020

El presente trabajo pretende lograr una sistematización reflexiva sobre los mapeos topográficos realizados en el territorio de la República Argentina a mediados del siglo XX. El presupuesto principal es que, lejos de estar centralizados en una institución, en tales mapeos topográficos intervienen numerosas instituciones nacionales. Metodológicamente, la investigación parte del análisis de un conjunto de datos cuantitativos publicados en el Catálogo Cartográfico del Consejo Nacional de Investigaciones Científicas y Técnicas del año 1967. En virtud de ello, la finalidad de este trabajo es visibilizar al vasto universo de instituciones cartográficas que intervinieron en los levantamientos topográficos del territorio argentino a mediados del siglo XX. Finalmente, en el trabajo se reflexiona si la heterogeneidad institucional interviniente en el mapeo nacional obedece a divisiones funcionales o bien a disputas de diversa índole.
La importancia de los métodos de diseño
Authors: Morales-Holguín Arodi
Published: November 2020

Los métodos desempeñan un papel preponderante en el diseño gráfico, condición que, a pesar de las transformaciones que se viven, suele perder relevancia tanto en la enseñanza como en la misma práctica profesional. Buscando encontrar elementos empíricos que permitan abordar dicha coyuntura, se desarrolló un estudio cualitativo a diseñadores gráficos en una universidad mexicana, donde se analizó la pertinencia de los métodos de diseño tanto en la formación como en la práctica profesional. Los resultados apuntan a que estos y su uso son valorados por un sector, así también considerados poco efectivos por otro, pues encuentran un desfase frente a la complejidad del entorno. Ello permite marcar posibles tendencias a partir de las cuales delinear estrategias que apunten al mejoramiento de la formación del diseñador en las universidades y su posible repercusión en la praxis.
Una mirada sobre el guion de Tejen
Authors: Moreno Pablo
Published: November 2020

El siguiente artículo analiza el guion de Tejen (Rabe, 2014) como continuación de las primeras conclusiones a las que se pudo arribar en la tesis de grado El guion moderno, un juego de escritura audiovisualizante. Se recogen para ello tres ejes, que vertebraron el desarrollo del trabajo: la práctica guionística como proceso de escritura audiovisualizante, la concepción de la estructura dramática como un sistema narrativo ajustado a reglas de juego internas, y una aproximación al análisis de relatos audiovisuales bajo una modalidad narrativa mixta.

Improving Community Health and Wellbeing Through Multi-Functional Green Infrastructure in Cities Undergoing Densification
Authors: Marques Bruno , McIntosh Jacqueline , Chanse Victoria
Published: November 2020

Evidence shows that maintaining a relationship with nature is essential for human health and wellbeing. This is of great importance when migration to urban areas is increasing globally and the need for nature as well as green and blue spaces as a source of recreation and relaxation is highly regarded for the health and wellbeing of local communities. Sustainable urban development and alternative design solutions to address urban compactness and densification are becoming increasingly important tools to counteract the adverse effects of urban sprawl. In the context of the highly compact bicultural capital city of Wellington, Aotearoa-New Zealand, this paper examines the effects of urban densification and compact city development in urban green spaces. It explores how architecture and landscape architecture can transform urban environments into desirable places to live and capitalise on the potentials of interstitial spaces, outdated zoning and changing land-use. To achieve that, it looks at green and blue infrastructure design solutions and opportunities that foster sustainable intensification and by offering new views for health and wellbeing that improve the social, cultural and environmental health of the city.

This study was performed to determine the effects of dietary supplementation with β-glucan on the growth performance and skin-mucus microbiota of sea trout, Salmo trutta L. in Latvia. The investigations were performed during an eight-month period (September 2018 – April 2019). A total of 15,000 sea trout were divided into five groups. The experimental fish were fed formulated diets enriched with 1 g kg−1 β-glucan (D2), 3 g kg−1 β-glucan (D3), 6 g kg−1 biological product BGN-2 (BGN-2) (D4), and 14 g kg−1 BGN-2 (D5). The control diet (D1) was not supplemented. Our results showed that fish fed diets D4 and D5 achieved significantly (P < 0.05) higher growth parameters compared to those fed the other diets. Pseudomonas and Aeromonas were detected as the main component of fish skin and gill microbiota. Beta-glucan did not affect the skin-mucus microbiota of the sea trout. All isolates were resistant to amoxicillin, ampicillin, cefalexin, and erythromycin and susceptible to gentamicin. The multiple antibiotic resistance index for all isolates was higher than 0.2.

The arrival of new customers along the new Iron Silk Road also brings new transport opportunities. The liberalization of railway transport has created many wagons over the railway market throughout the EU, especially in the field of freight transport. Choosing the preferable carrier that can fit the needs of customers is challenging. Each rail freight operator currently shapes its profile by focusing on a specific group of commodities as a matter of priority. By specializing, they gain a dominant market position in their sector that helps them to maintain and expand their clientele. The article aims at bringing a decisive system with clear rules and standards for choosing the right business partner in the freight railway market. The article is designed as a case study that starts with an analysis of four different freight carriers. Other parts of the article are about the evaluation of their ability to meet the needs of a customer.

Aim. The aim of this study was to assess the anti-CMV antibody titre, the presence of genetic material of the virus in the plasma of elderly residents of nursing homes and the impact of the CMV infection on the risk of death.

Material and methods. The number of 202 residents of a nursing home in Warsaw, aged 65 and over, were observed for 1095 days (3 years) between 2015 and 2018. During this period 126 (62.4%) residents died. Plasma CMV DNA levels were assessed using real-time PCR. Anti-CMV antibody titre was measured with the use of commercially available ARCHITECT CMV test.

Results. No genetic material of the CMV was found in the studied group of the residents. The mean IgG titre did not differ between those who survived and those who deceased (p=1). Pearson’s Chi-squared test and Fisher’s exact test did not reveal any differences in the rate of deaths among the groups of seronegative, seropositive < 250 IgG [Au/ml], and seropositive > 250 IgG [Au/ml] residents. Kaplan-Meyers survival curves confirmed these results.

Conclusions. We did not demonstrate that CMV infection or the anti-CMV antibody titer have any effect on the risk of death in the study group.

: The research aim was to analyse the relationship between emotional intelligence and performance of public sector employees, but we also looked at correlations between two dimensions of emotional intelligence and two particular dimensions which impact organizational performance. This study was conducted on employees from Romanian public sector organizations and in order to achieve the purpose of the research we developed a quantitative methodology based on questionnaire. All the measures we used in this study were drawn from established previous research and specially adapted and tailored for employees from public sector. The study was conducted through a quantitative methodology, using a conceptual deductive research approach based on conceptual framework in order to test the hypotheses. For the statistical analysis, we used the package SPSS Statistics 22.0, through which we generated descriptive analyses and several parametric tests aimed at achieving the main purpose of our research. The results of our research are relevant for leaders and human resources managers of public sector organizations, but they can also be useful for practitioners and scientific community from around the world. The conclusions of our research demonstrate that emotional intelligence is important for any organization and does have a statistically significant impact on how performance is measured and encouraged in Romanian public organizations. Although the correlation is not the strongest, the 0,321 Pearson Correlation coefficient is enough to warrant public organizations investing in recruiting and retaining emotionally intelligent workforce if they care about performance.
