Inappropriate arguments as a communication technology: types, peculiarities, and countering mechanisms
Authors: Katunin Aleksandr Viktorovich
Published: January 2022

This article is dedicated to such type of communication technology as inappropriate arguments. Special attention is given to clarification of the key concepts of the topic – “argumentation”, “appropriateness”, “inappropriateness”, and “context”. The original classification is provided to the types of inappropriate arguments. The author reveals the contextual peculiarities of using different types of inappropriate arguments; analyzes the specificity of using inappropriate arguments; as well as offers possible countering mechanisms. Particular examples of using incorrect arguments are confirmed by links to recorded live dialogues. The article employs the methods of intent analysis and comparative analysis. The Russian tradition of studying the theory and practice of argumentation features a number of research that touch upon the problem of inappropriate arguments. However, the study of arguments is just a part of the whole variety of communication technologies. The novelty of this work consists in the centralized, systematized presentation of the assemblage of variations of inappropriate arguments. The types of inappropriate arguments are illustrated on the specific examples from literature, cinematography, cultural -historical, social and political spheres of society. The acquired results can be valuable for the development of lecture courses on the theory and practice of argumentation, students majoring in philosophy, and audience interested in modern research dedicated to communication technologies.

Published: January 2022

The Botswana College of Distance and Open Learning (BOCODOL), presently Botswana Open University (BOU), was founded to provide nation-wide learning opportunities for out-of-school young adults using the Open Distance Learning (ODL) mode. The BOU used a number of strategies to enable it to deliver on its mandate; one such strategy being the implementation of e-Learning, following contemporary delivery trends internationally within the ODL field. This paper reports on the findings of a study that sought to investigate the extent to which organisational efforts (means) were able to produce organisational results (ends) and associated societal impact in e-Learning implementation at BOCODOL. The diffusion of an innovation theoretical framework and Organisational Elements Model (OEM) conceptual framework was used to underpin the study. Qualitative data collection methods of inquiry (ethnography, document analysis and written interviews) were used. After providing a relevant literature review, the paper firstly reports on the Botswana e-Learning landscape, as well as the nature of inputs and processes serving as means to e-Learning implementation at BOU. Secondly, it reports on the products, successes and challenges as well as outputs and outcomes during e-Learning implementation at BOU. The methodology and findings of the study directing this paper are discussed, and lastly, the paper acknowledges the impact of organisational results (outputs and outcomes) encountered during e-Learning implementation and their implications to the ODL field.

The author draws attention to the similarity of the Scythian, Thracian and Macedonian iconography of coins, as well as to the similarity of the evidence of the written tradition when describing the founding of dynasties. The author comes to the conclusion about the possible Thracian and Scythian influence on the formation of the myth about the origin of the Argeads.
Epistemic Rationality in Political Theory
Authors: Shevchenko A. A.
Published: January 2022

The paper presents a brief analysis of the procedural approach towards constructing liberal political conceptions of justice and democracy. Treatment of J. Rawls’s evolution shows the negative consequences of abandoning external substantive criteria for theory evaluation, including efficiency, justification, truth. It also offers justification for the “epistemic turn” in contemporary political theory. The return of classical epistemological set of tools will help to strengthen the justification and legitimation of philosophical and political conceptions of justice and democracy by overcoming the key limitations of the procedural approach.
General Relativity and Causality, Reasoning from Metaphysics, and E. J. Lowe’s Ontology
Authors: Golovko N. V.
Published: January 2022

The paper aims to show the importance of reasoning “from metaphysics” in the course of a consistent interpretation of the “against neoscholasticism” thesis (J. Ladyman). The idea that “the subject of metaphysics is metaphysical possibilities, and science determines which of them are actually achieved” (E. J. Lowe, J. Katz, etc.) reinforces the role of reasoning “from metaphysics” within the field of metaphysics of science. The general theory of relativity violates the common prevailing intuition that “causality is the subject of local physical interaction” (J. Bigelow). Interpretation of causality in terms of “forces” and “coming into” within the framework of E. J. Lowe's ontology makes it possible to talk about causality in terms of “finding” and “going out” of existence of the corresponding modes of objects connected by a formal “causal relationship”. The transition to E. J. Lowe's ontology helps not only to overcome the intuition of the locality of causality, but also reveals in its own way, for example, such seemingly simple common intuitions as the dependence of the truth of propositions on time or the understanding of time as a dimension. All this once again brings us back to the understanding of the importance of the fact that a scientist, constructing or interpreting a scientific theory, as a rule, uses non-trivial philosophical assumptions that should be the subject of its own philosophical analysis.
Study of Flow around a Trapezoidal Model of a Small-Sized UAV into Turbulent Wake
Authors: Pavlenko A. M. , Bykov A. V. , Zanin B. Yu. , Katasonov M. M.
Published: January 2022

Investigations of the structure of the flow near the surface of a trapezoidal model of a small unmanned aerial vehicle were carried out when it enters a narrow turbulent wake. All experimental data were obtained in a wind tunnel at subsonic flow velocities. A feature of the work was that the study of the flow around the model was carried out at full-scale (flight) Reynolds numbers. Using the soot-oily visualization method, data on the features of the flow around the model were obtained, taking into account such factors as the angle of attack, the presence and absence of a source of external disturbances that generated a turbulent wake. The experiments were carried out in two flow regimes: at a zero angle of attack, when there are local separation bubbles on the wing, and at a large (supercritical) angle of attack of 18 degrees, when there is a global stall of the flow from the leading edge. It was shown that the turbulent wake has a significant effect on the nature of the flow near the model surface in both cases. Local separation bubbles gradually decrease in size with a decrease in the distance between the sources of disturbances and the wing. Large-scale vortices significantly decrease in geometrical dimensions and shift towards the side edges in the event of a global stall of the flow, thereby increasing the region of the attached flow on the model surface.

Authors: Akinin S. A. , Starov A. V.
Published: January 2022

The results of computational and experimental studies of a model of a hypersonic convergent air intake are presented. Experimental studies were carried out in a hot-shot wind tunnel IT-302M SB RAS at a Mach number M = 5.7 and an angle of attack α = 4 °. Numerical modeling was carried out in a three-dimensional setting in the ANSYS Fluent software package. The calculations were carried out in 4 versions using different turbulence models: k-ɛ standard, RNG k-ɛ, k-ɷ standard and k-ɷ SST. The features of the flow structure are established. The pressure distributions on the compression surfaces and in the air intake channel are obtained. The separated flow at the entrance of the inner channel was studied. It was found that the use of various turbulence models has a significant effect on the size and position of separation. The best agreement between the calculated and experimental data on the level of static pressure was shown by the variant with the k-ɛ standard turbulence model.

Experimental results demonstrating long-term stability of the operation of our atmospheric quantum cryptography setup using the BB84 protocol and polarization coding are presented. It was shown that the “sifted” quantum key distribution rate and the quantum bit error rate in the key remained constant for 1 hour and were equal to 10 kbit/s and 6.5 %, respectively, at a distance between the transmitter and the receiver equal to 20 cm. Theoretical dependences of the secret quantum key generation rate on a quantum channel transmission coefficient for single-photon detectors, which were used in this experiment, and for new detectors with a reduced level of dark pulses are given.
The Physics Laboratory Works – Individualized Computer Simulations
Authors: Zaikin A. D. , Suhanov I. I.
Published: January 2022

The physics laboratory-works creating and operating computer simulations experience is described. A significant amount of laboratory works can be classified as a “black box”. The studied physical phenomenon is hidden from direct observation, the control is carried out by means of electrical measuring devices. It is difficult to distinguish physical reality from its imitation when performing such work, so the virtualization of this one does not require realistic images. The schematic representation of the laboratory installation greatly simplifies the process of creating a simulator. A unique set of installation parameters is formed for each student performing laboratory work on the simulator, which contributes to the independence of the student's work. These parameters are stored in Google Sheets. Their transfer to the laboratory work’s html-template is carried out in encrypted form through the Google Apps Script service. Virtual laboratory work is implemented as a cross-platform web application.

Authors: Godse Kiran , De Abhishek , Shah Bela , Girdhar Mukesh , Shankar Krupa , Sarda Aarti , Dhoot Dhiraj , Barkate Hanmant
Published: January 2022

Objectives:

There are multiple guidelines for chronic spontaneous urticaria (CSU) by various dermatological associations, but in real-world practice in India, different approaches have been noted. In this paper, we courted to determine these different approaches in CSU management, adherence to various CSU guidelines, and the reasons for deviation from guidelines amidst dermatologists in India.

Materials and Methods:

A net-based questionnaire was created and validated by five panelists experienced in CSU management and then was circulated to all dermatologists in India in August 2020 for real-world management scenario.

Results:

We received 880 completed response out of 2235 response. Most of the dermatologists (97%) were aware of some urticaria guidelines. Although many of them follow guidelines about three forth of them reported to deviate from it sometimes. The most common reason for deviation was rely on clinical experience as opted by 53% of respondents. Dermatologists who follow guidelines also investigate routinely in terms of complete blood count, the erythrocyte sedimentation rate, and thyroid-stimulating hormone as compared to those who do not. About 70.5% of the dermatologist prescribe second-generation antihistamine (SGAH) at approved dose as the first line of treatment whereas 63.6% up dose it as second line of treatment. Surprisingly, 68% prescribe first-generation antihistamine in the evening and SGAH in the morning as combination therapy in CSU.

Conclusion:

From the findings of the present study, it can be strongly implied that guidelines play a vital role in delivering superior attributes of patient care although 75% of dermatologists deviated from it. Main reasons for deviance are reliability on self-clinical proficiency and consideration of economic impediments. Both these factors need to be worked upon by continuous medical education of dermatologists and more pharmaco-economic research.

Published: January 2022

Objectives:

Chronic spontaneous urticaria (CSU) is defined as short lived (< 24h) wheals occurring spontaneously without any triggering factors, daily or almost daily for at least 6 weeks. Though CSU is mainly a Type 1 hypersensitivity reaction, earlier studies suggested contact allergy may have some role to play an important role in the etiopathogenesis of CSU. The objective of the study is to find out the relevance of patch test in the etiopathogenesis of and its correlation with serum IgE level.

Materials and Methods:

Thirty-one patients of CSU were thoroughly evaluated for clinical and laboratory parameters. We conducted patch testing with Indian Standard Series (ISS) in all of them and tried to find out the relevance of every positive reaction. Relevant positive cases were asked to avoid exposure for 2 months and were maintained only in breakthrough antihistamines. Furthermore, correlation of positive patch test reaction with high IgE and eosinophil count were studied.

Results:

Seventeen (55%) cases came positive for patch test. Potassium dichromate, lanolin, benzocaine, and fragrance mix were the most common offenders. Patients with very high IgE count had patch test positivity with multiple allergens. Seven of the fifteen patients who had relevant positive patch results could be followed up to remission; three were lost to follow-up.

Conclusion:

Patch test with ISS may give important clue to in a subset of patients of CSU and thus may be considered an important part of routine investigations of CSU.

Published: January 2022

The aim of the article is to study the trends of key indicators of financial and economic condition of the construction sector of the national economy and forecast the volume of construction products. The relevance of the research topic is due to the fact that the state of the construction sector of the national economy is an indicator of socio-economic development of the state, only in developing regions, construction has a steady trend and constant activity among economic activities. Current trends in construction in Ukraine are characterized by the implementation of programs "New Construction", "Reconstruction", relevant changes in legislation, etc., where these reforms bring the sector to a fundamentally different level of development. The study was conducted using the following general and special scientific methods: generalization, financial and economic analysis, synthesis, forecasting, statistical, graphical. The study found that the financial indicators of the construction sector of the national economy for the period 2016-2020 are gradually declining, and economic indicators are characterized by a positive growth trend only until 2019. In 2020, significantly worsened all financial and economic indicators of the construction sector. As a result of decomposition analysis, we obtained a time series of volumes of construction products, which is devoid of trend and seasonal component. The method of constructing autoregressive models was used. The built models are high quality and describe 99% of the original data. With a probability of 95%, the obtained models are statistically significant. The degree of accuracy of the model is calculated and it is found that the obtained model provides a forecast of sufficient accuracy. A slight decrease in the volume of construction output is forecast, by an average of 1.5%. Compared to the same period in 2020, there is a growing trend in the volume of construction products. In June 2021, the growth of construction output compared to June 2020 is projected at 30%. It is proved that the construction sector of the national economy really needs support and transformation in accordance with the new economic conditions.

Published: January 2022

The article is devoted to the study of the peculiarities of regulating the recourse period to the administrative court from the point of view of due process. Clear up the issue to what extent the consolidation and regulation of the recourse period qualifies the requirements of the legal procedure, namely: clear legislative regulation; inadmissibility of violation of the rights, freedoms and interests of the parties; clear structuredness and regulation. The scientific work investigates the essence of the term circulation term and considers the feasibility of introducing it. An attempt was also made to compare the recourse period with the limitation, arguments are given why the introduction of the terms of appeal in administrative proceedings is not identical to the limitation in civil proceedings. Different positions are considered, referring to the practice of the Supreme Court and the opinions of scientists, why, on the one hand, the limitation cannot be introduced in the administrative process from the point of view of the principle of legal certainty, and on the other hand, how the recourse period violates the right to access to justice. The main attention is paid to the role of the Supreme Court in the formation of approaches to the application of limitations. The concept of contra legem, which is inherent in the countries of the Anglo-Saxon legal family, is considered and is used in cases where there is a need to deviate from the enshrined norm at the legislative level in order to avoid literal application of the law and not make an absurd or unfair decision. The thesis is emphasized, despite the fact that the Supreme Court sometimes deviates from the formally prescribed norms, however, this is the essence of the cassation proceedings: it is an additional guarantee of the protection of subjective rights by correcting judicial errors, as well as a kind of judicial control. The specific decisions of the Supreme Court are considered, in which the approaches to the practice of applying the recourse period have been changed. On the basis of the decisions of the Supreme Court, it was investigated how the Supreme Court by its decisions affects and changes the recourse period fixed at the legislative level, the key positions of the Supreme Court are highlighted, which today are guiding for the subjects of appeal to the administrative court.

Published: January 2022

Клиническое значение делеции района q21 хромосомы X у мужчин все еще плохо изучено. Было показано, что делеция Xq21, включающая гены POU3F4, CHM и ZNF711, может приводить к глухоте, умственной отсталости и хороидеремии. Несмотря на тяжелые симптомы, наблюдаемые у пробандов-мужчин, большинство носителей женского пола бессимптомны или имеют незначительные фенотипические проявления. Представлена клиническая и молекулярно-цитогенетическая характеристика случая делеции района q21.1-q21.31 хромосомы X, выявленной при проведении хромосомного микроматричного анализа у пациента с задержкой психоречевого развития, лицевыми дизморфиями и тугоухостью. Такая же делеция была выявлена у практически здоровой матери. Наши данные способствуют дальнейшему пониманию корреляции между делецией Xq21 и аномальным фенотипом.

Deletions on the X chromosome can lead to serious birth defects. Deletions in Xq21 cause various congenital defects in males including choroideremia, deafness and mental retardation, depending on their size and gene content. Only a limited number of patients with Xq21 deletions has been reported. It has been shown that deletions of the adjacent Xq21 genes, including the POU3F4, CHM and ZNF711 genes, can lead to deafness and mental retardation syndrome and choroideremia. Despite the severe symptoms exhibited by male probands, most female carriers are asymptomatic or exhibit only a mild phenotype. The article presents the clinical and molecular-cytogenetic characteristics of a case of deletion of the Xq21.1-q21.31 region of chromosome X, revealed during chromosomal microarray analysis in a patient with delayed psycho-speech development, facial dysmorphisms and hearing loss. The same deletion was found in an apparently healthy mother. Our study confirms the causative effect between the Xq21 deletion in males and choroideremia, deafness and mental retardation.

Для увеличения масштабов производства и переработки растительного сочного сырья и сокращения использования химических пестицидов применяются различные виды физической обработки, в том числе электромагнитные поля (ЭМП). Представлены результаты изучения влияния ЭМП крайне низкой частоты (ЭМП КНЧ) на активность пероксидазы и содержание полифенольных веществ в белокочанной капусте сорта Белтис и цветной капусте сорта Ардент при хранении. Образцы обрабатывались ЭМП (25 Гц, 10 мТл, 30 мин) на лабораторной экспериментальной установке и хранились в течение 21 сут при t (4±1)°С и относительной влажности воздуха (75±3)%. Установлено, что обработка капусты белокочанной привела к увеличению активности пероксидазы на 70% через 7 сут, а через 21 сут хранения - увеличению пероксидазы на 25% и уменьшению полифенольных веществ на 13,7%. В обработанных образцах цветной капусты увеличилась активность пероксидазы на 54% через 7 сут и на 62 % через 14 сут хранения, а также количество полифенольных веществ на 8% через 21 сут хранения. Изучение закономерностей влияния обработки растительного сочного сырья ЭМП КНЧ на индукцию резистентности позволяет разработать на их основе новые способы хранения.

In order to increase the scale of production and processing of vegetable juicy raw materials, it is necessary to timely develop new efficient, economical and environmentally friendly storage technologies. One possible way to reduce the use of chemical pesticides is through the use of various types of physical treatments, including electromagnetic fields. The article presents the results of studying the influence of extremely low frequency electromagnetic fields on the peroxidase activity and the total polyphenolic content in the white cabbage cultivar Beltis and the cauliflower cultivar Ardent during storage. The objects of research were treated with an electromagnetic field (25 Hz, 10mT, 30 min) in a laboratory experimental setup and were stored for 21 days at a temperature of 4±1°С and air relative humidity of (75±3)%. It was found that, in comparison with the control, the treatment of white cabbage leads to an increase in peroxidase activity by 70% after 7 days and by 25% after 21 days of storage, and an increase in peroxidase by 25% and a decrease in polyphenolic substances by 13,7% after 21 days of storage. It was also found that, in comparison with the control, the treatment of cauliflower leads to an increase in peroxidase activity by 54% after 7 days and by 62% after 14 days of storage, and leads to an 8% increase in the content of polyphenolic substances after 21 days of storage. The study of the regularities of the influence of the treatment of vegetable juicy raw materials with electromagnetic fields of extremely low frequencies on the induction of resistance can make it possible to develop new storage methods on their basis.

Published: January 2022

Disordered and porous metal oxides are promising as earth-abundant and cost-effective alternatives to noble-metal electrocatalysts. Herein, we leverage non-saturated oxidation in plasma-enhanced atomic layer deposition to tune structural, mechanical, and optical properties of biphasic CoOx thin films, thereby tailoring their catalytic activities and chemical stabilities. To optimize the resulting film properties, we systematically vary the oxygen plasma power and exposure time in the deposition process. We find that short exposure times and low plasma powers incompletely oxidize the cobaltocene precursor to Co(OH)2 and result in the incorporation of carbon impurities. These Co(OH)2 films are highly porous and catalytically active, but their electrochemical stability is impacted by poor adhesion to the substrate. In contrast, long exposure times and high plasma powers completely oxidize the precursor to form Co3O4, reduce the carbon impurity incorporation, and improve the film crystallinity. While the resulting Co3O4 films are highly stable under electrochemical conditions, they are characterized by low oxygen evolution reaction activities. To overcome these competing properties, we applied the established relation between deposition parameters and functional film properties to design bilayer films exhibiting simultaneously improved electrochemical performance and chemical stability. The resulting biphasic films combine a highly active Co(OH)2 surface with a stable Co3O4 interface layer. In addition, these coatings exhibit minimal light absorption, thus rendering them well suited as protective catalytic layers on semiconductor light absorbers for application in photoelectrochemical devices.
LOAD FORECASTING FOR MONTHS OF THE LUNAR NEW YEAR HOLIDAY USING STANDARDIZED LOAD PROFILE AND SUPPORT REGRESSION VECTOR: CASE STUDY HO CHI MINH CITY
Authors: Nguyen Tuan-Dung , Nguyen Thanh-Phuong
Published: January 2022

Load forecasting plays an important role in building business strategies, ensuring reliability and safe operation for any electrical system. There are many different methods, including: regression models, time series, neural networks, expert systems, fuzzy logic, machine learning and statistical algorithms used for short-term forecasts. However, the practical requirement is how to minimize the forecast errors to prevent power shortages or wastage in the electricity market and limit risks. For Asian countries (such as Vietnam) that use lunar calendar, one of the most difficult and unpredictable issues is the Lunar New Year (usually in late January or early February). There is a deviation between the solar calendar and the lunar calendar (the load models are not identical). Therefore, it often leads the forecast results of algorithm for this period with large errors. The paper proposes a method of short-term load forecasting by constructing a Standardized Load Profile (SLP) based on the past electrical load data, combining machine learning algorithms Support Regression Vector (SVR) to improve the accuracy of load forecasting algorithms.
ENSINO DE CIÊNCIAS NA ERA DA PÓS-VERDADE: CONSIDERAÇÕES ACERCA DO DISCURSO PRESENTE EM FAKE NEWS
Authors: Britto Daniella Maria Coelho de , Mello Irene Cristina de
Published: January 2022

As Fake News não são novidade na história da humanidade. No entanto, quando as Fake News passam a veicular pretensos conhecimentos científicos, deve-se refletir como o Ensino de Ciências tem produzido conhecimentos e enfrentado os desafios da pseudociência nas salas de aula. Estamos vivenciando um fenômeno social chamado de “pós-verdade”, termo utilizado em circunstâncias onde pessoas atribuem maior importância a sentimentos e crenças do que aos fatos em si, o que favorece a disseminação de Fake News. Este trabalho teve como objetivo analisar o discurso presente em algumas Fake News – relacionadas à origem do vírus SARS-CoV-2 e os possíveis tratamentos para a Covid-19 – a partir das cenas da enunciação propostas por Dominique Maingueneau, além de discutir o papel do ensino de Ciências diante de tal cenário. O trabalho foi desenvolvido a partir de uma abordagem qualitativa, com elementos de pesquisa bibliográfica e exploratória. Os resultados mostraram que nas Fake News o discurso do enunciador geralmente flui sem dificuldades, em acordo com convicções prévias do leitor; a fonte parece familiar ou confiável (principalmente quando a cenografia se apropria do discurso científico); a cena genérica – redes sociais – favorece a formação de bolhas sociais. Consideramos que o ensino de Ciências precisa explorar as evidências que sustentam determinada informação ou teoria. Julgamos que saber lidar com informação de caráter duvidoso na era da pós-verdade seja uma questão estrutural que depende de uma formação inicial e continuada adequada para professores e, como consequência, para estudantes do ensino básico.

Objectives: The maintenance of the postural balance is fundamental for the daily living activities, as well as for the practice of physical exercise. However, the aging process and sedentary behavior (i.e., large sitting time) lead to changes biological systems, impairing postural balance with consequent increased falls risk. On the other hand, physical activity practice is a protective factor against these trends. The aim of this study is to investigate the influence of physical activity profile and sedentary behavior on postural control in community-dwelling old adults.Methods: This is a cross-sectional study including 208 community-dwelling old adults, which were stratified as sufficiently or insufficiently physically active and with or without sedentary behavior. Then, they were grouped as follow: G1 (sufficiently physically active and without sedentary behavior), G2 (insufficiently physically active, but without sedentary behavior), G3 (sufficiently physically active, but with sedentary behavior), and G4 (insufficiently physically active and with sedentary behavior).Results: Stabilometric parameters (sway area, total length of center of pressure [CoP] trajectory, and the mean velocity of CP displacement) were obtained to evaluate the postural control. There was significant difference between G1 and G4 on mean velocity of CoP displacement (p < 0.05).Conclusions: The coexistence of sedentary behavior and insufficient physically active profile seem to impact negatively on postural control.
INTEGRATION OF IMMIGRANTS AS THE MOST IMPORTANT COMPONENT OF THE THIRD STAGES OF POPULATION MIGRATION — ADAPTATION (THEORETICAL QUESTIONS)

The issues of the integration of immigrants in the Russian Federation in 2021 are fundamentally new, if we consider them in the coordinates of the integration crisis, and at the same time, put forward by President Putin V.V. the task of reaching the upward dynamics of the number of Russians, with a persisting pandemic, until 2025. This requires a theoretical rethinking of the conceptual apparatus, not only in relation to the concept of "integration of immigrants". Not only in terms of identifying indicators of this process. But also more broadly — in relation to the definition of the concept of population migration, in general. The article makes a methodological attempt to show that when considering integration, as an integral part, the final, third stage of population migration — adaptation, in accordance with the theory of three stages of population migration, most fully presented in the works of L.L. Rybakovsky, it seems possible more clearly to determine the tasks of the integration policy of the Russian Federation. Since this approach clearly separates the processes of adaptation, integration, arrangement at the stage of settling — in at the place of settling. Gives a clear understanding that integration is the prerogative of only migrants who belong simultaneously to the type of interstate and permanent migration. And only they, objectively, should be the object of integration policy, which should be an integral, integral part of immigration policy. But with its own specific tasks for its object — interstate permanent migrants. Such a methodological approach, to the greatest extent, corresponds to an individual approach to the regulation of the integration process, makes it possible to more effectively use the mechanism of integration contracts to increase the responsibility of the individual and society. Implemented at the local, municipal level, at the same time — the level of self — government in the Russian Federation, such an individual method of integration policy is most consistent with the figurative understanding of integration as a road with oncoming traffic, since it also contributes to an increase in the civic identification of immigrants and national solidarity of society. It implies a targeted mutual determination of rights and obligations.

In the previous article of authors [4], the main regions-attractors in Russia were identified: the Moscow metropolitan agglomeration, the St. Petersburg agglomeration, the Black Sea regions of the South of Russia, Krasnodar Territory, the Republic of Crimea, the city of Sevastopol, the Republic of Adygea, the Kaliningrad region in the Baltic. Most of the interregional migration flow is directed to these regions. The general picture of interregional migrations is more complicated and is not limited to the main regions as attractors. It is advisable to consider more fully the flows of interregional migrations in Russia. To analyze interregional migration, we used Rosstat data for 2017–2019. The indicators were taken in total for 2017–2019. to exclude annual random fluctuations, to more accurately identify the nature of migration. We excluded the Republic of Ingushetia from consideration due to the complexities and peculiarities of statistical recording of the migration loss of the population in this region. The study was carried out on the basis of approaches to regional analysis of demographic processes, which were developed by scientists-demographers and economists in various scientific centers of Russia, including Rybakovsky O.L., Borisova L.M., Chernyshev K.A., Mishchuk S.N., Khilazhevа G.F., Ryazantsev S.V.

El arroz es un cultivo de importancia en Ecuador y uno de los cereales más consumidos en este país. Sin embargo, bajo ciertas condiciones, puede contaminarse y contener toxinas exógenas como las micotoxinas. En este sentido, la presente investigación se realizó con la finalidad de levantar información sobre la presencia de las micotoxinas zearalenona y aflatoxina total en arroz sin cáscara, mediante el uso del método inmunológico ELISA, debido a que estos contaminantes comprometen la inocuidad de los alimentos y representan un riesgo para la salud pública. Para ello, se tomaron 41 muestras de los cantones con mayor superficie sembrada de arroz del Ecuador y se analizaron con el método de inmunoensayo ELISA competitivo. Los resultados revelaron la presencia de zearalenona en rangos de concentración entre 1-20 μg/kg para el 34 % de las muestras y de 41-60 μg/kg para el 2 % de las muestras; por otro lado, no se detectó la presencia de aflatoxina total en las muestras recolectadas. Se concluye que se detectó la presencia de la micotoxina zearalenona en varias muestras de arroz, pero ventajosamente todas las muestras positivas arrojaron valores por debajo del límite máximo establecido por la Unión Europea (Reglamento (CE) N° 1881/2006 de la Comisión) de 100 μg/kg para zearalenona y de 4 μg/kg para aflatoxina total.

Las celdas de combustible microbianas son dispositivos que permiten transformar energía química almacenada en compuestos orgánicos en energía eléctrica, utilizando microrganismos depositados sobre un electrodo. Entre las ventajas que posee esta tecnología se destaca la posibilidad de limpiar o tratar matrices acuosas como aguas residuales. A continuación se reporta, como prueba de concepto, la construcción de una celda de combustible microbiana empleando materiales reciclados o de bajo costo. El consorcio de bacterias electrogénicas utilizadas se aisló de sedimentos del embalse Amaluza, en Cuenca, Ecuador. La celda se puso en funcionamiento utilizando aguas residuales domésticas reales, obtenidas del barrio Ubilus de la parroquia Pintag del cantón Quito, Ecuador. La celda de combustible construida generó una densidad de potencia de 40 mW/m2 con un porcentaje de remoción de materia orgánica cercano al 80 %. Siguiendo el concepto de economía circular, se midió la concentración de nitrógeno, fosforo y potasio en la biomasa producida por la celda para su posible aplicación como aditivo ecológico de fertilizantes.
