In this article, we have considered the state of development of high-power horizontal wind turbines. The most common wind turbines for operation with variable wind flow speed usually include a frequency converter to ensure the compatibility of generator with network. It leads to decrease in the efficiency of wind energy conversion system, while the use of direct connection of the generator to the axis of wind wheel leads to a significant increase in the weight and cost of the generator. The wind turbine with aerodynamic multiplication is an alternative to such systems. Its prototype with 750 kW power is manufactured and studied in Ukraine. This wind energy conversion system with the synchronous or induction generators offers the property to generate energy under optimal condition with invariable rotational speed of generator rotor within the wide range of variable speed of wind flow. In this case, it is not necessary to apply the frequency converter that contributes to increasing the efficiency and reducing the cost of wind turbine. As shown, the relative performances of mass, cost and efficiency of generators in proposed system comparatively to conventional one depend on the multiplication factor (i.e. ratio of the rotational speeds of wind turbine and generator). When the power of wind turbines is from 750 to 2500 kW, the multiplication factor is within the limits of 10.72 to 4.75. The theoretical and experimental study shows that the wind turbines with aerodynamic multiplication can be competitive as compared to conventional horizontal wind turbines. This article is aimed to comparative analysis of the quantitative and qualitative characteristics of the equipment used in high-power horizontal wind turbines with direct connection of generators to the axis of wind turbine and in wind turbines with aerodynamic multiplication.

Renewable energy sources (RES) affect the technical and economic parameters of electrical grids. In particular, with the increase in the amount of electricity in the EPS balance produced by RES, it is relevant to determine the power and electricity losses in electric grids caused by flows of electricity from RES. The method, algorithm and program for determining the component of power and electricity losses from RES in the total losses of electrical grids have been developed. The basis of the method is a mathematical model of the electrical grid for determining losses, which uses the current distribution coefficients in the circuits of the circuits from RES nodes and node voltages. As a result, a matrix of power loss distribution coefficients is formed in the branches of the circuit depending on the power in the nodes of the circuit. The voltages during the formation of the loss distribution matrix are determined based on the results of the calculation of steady-state modes of the electrical network or according to experimental measurement data. It is shown that the values of electricity losses in electrical grids caused by RES can be used during the operational planning of the electricity balance in the EPS and, since they are addressable, their cost can be compensated accordingly.

Mathematical models are given for forming the schedule of electric energy supply from hydroelectric power stations for bidding in the "day-ahead" market segment. The formulation of the task of forming the supply schedule as a task of optimal use of available hydro resources for the production of electrical energy at hydroelectric power stations is described. The need to perform two-stage optimization based on price and non-price criteria is substantiated. It is proposed to consider non-price criteria by means of penalty functions in the objective function of optimization by price criteria. A system of basic technological limitations, as well as equations for control and adjustment of the reservoir filling level, is given. The results of practical calculations for both optimization options are presented. References 9, figures 3.

In this paper, we consider the simultaneous sign changes of coefficients of Rankin–Selberg L-functions associated to two distinct Hecke eigenforms supported at positive integers represented by some certain primitive reduced integral binary quadratic form with negative discriminant D. We provide a quantitative result for the number of sign changes of such sequence in the interval (x, 2x] for sufficiently large x.
(Dis)trust in action
Authors: Dinucci Almeida Bühler Velasco Amanda , Leite de Oliveira Maria do Carmo , Cortes Gago Paulo
Published: November 2023

Recent public statistics on law enforcement activities show that the Brazilian police are among the nation's least trusted institutions. The legitimacy of policing derives from a perception of fair and justifiable rules applied fairly to all citizens, but police actions in low-income favela communities in Brazil have been denounced repeatedly for their arbitrary nature, abuse of authority and truculence. Most studies analysing trust in the police have been conducted through surveys. In this paper, however, we examine trust in action, through a video analysis of a stop-and-check operation undertaken by police officers in a low-income favela community in Rio de Janeiro. The analysis of this interaction shows that distrust steered the actions of both sides: the officers’ decision to stop somebody and use force reflects this distrust in people living or moving around in these narrow alleys, while the suspect's resistance and calls for help demonstrate his fear and distrust of the police. We believe that examining police actions through a micro-analytical lens can contribute to training law enforcement officers, encouraging deeper reflection on factors that undermine trust in this institution.

Lusatian Serbs, also called Sorbs, are people living in Upper, Middle and Lower Lusatia. This small nation is a remnant of the Slavic settlement in East Germany (Brandenburg and Saxony). Lower Lusatia now lies in the state of Brandenburg, and Upper and Middle Lusatia in the Free State of Saxony. According to official data, in these areas there are approximately 50,000 – 60,000 Lusatian Serbs, of which it is assumed that two-thirds reside in Saxony and one-third in Brandenburg. The article draws attention to formal and legal issues aimed at protecting the culture and the Lower Sorbian language. The analyses carried out concern the general provisions of the European Union, Germany and more detailed guidelines adopted in Brandenburg. Legal acts are important formal means of protection, the effectiveness of which is expressed by the way of practice. Unfortunately, in Brandenburg, many of the existing regulations have no proper effect on everyday life or are distorted. The article is an attempt to identify the assumptions with the implementation, to recognize the limitations, but also to discuss the directions of improving the existing state.
Edukacja seksualna w Polsce i systemach edukacyjnych wybranych krajów – modelowe rozwiązania i międzynarodowe inicjatywy
Authors:   Uniwersytet Zielonogórski, Dec-Pietrowska Joanna
Published: November 2023

The article is aimed at the analysis of literature, international documents, legal regulations and research reports on the implementation of formal sexuality education in selected countries. There are many contradictions among researchers about the definition of sexuality education, its scope, the age from which it should be taught and learnt, people who should be its providers, its content and forms. These discrepancies are also present in the public sphere, where two strongly polarized discourses (the conservative and liberal) exist. National policies regarding sexuality education vary in the European Union. In some countries sexuality education has the status of a compulsory subject, is regulated by relevant acts, similarly to teachers training for this subject. In others, sexuality education curricula lack solid legal and theoretical basis. The analysis of selected documents and acts shows that the most effective type is the holistic sexuality education, which being part of the cultural sensitivity approach, addresses the development of knowledge and skills of education recipients, as well as the elaboration of appropriate attitudes towards positive sexuality and sexual and reproductive health. The existing research indicates also that the availability of data on sexuality education should be improved and further analysis is needed to enable better assessment of the situation, to ensure the evidence-based policy creation and strengthen the best identification practices.
Religijność i poczucie tożsamości studentów z Czech, Polski i Słowacji
Authors:   Uniwersytet Śląśki w Katowicach, Grabowska Barbara
Published: November 2023

The subject matter explored in the article include the issues related to religiousness of university students. This category comprises their denominational structure, their attitude to religion, their self-evaluation of the essence of religion in life, the frequency of participation in religious practices. These categories are shown in relation to their sense of identity. The research with the use of the survey method was conducted among students from the Czech Republic, Poland and Slovakia who live in culturally diverse territories. The research results show the ongoing changes in Polish and Slovak societies. Young people take advantage of the possibility of making choices and their choices concern not only education and professional paths, but also the beliefs, behaviour and activities in the religious sphere. The surveyed students’ freedom of choice is manifested, among others, in their sense of a multidimensional identity and in the consciousness of belonging to the Church. Among the surveyed university youth – in the Czech Republic, Poland and Slovakia – one can observe the individualization of religiousness in the form of the departure from religious affiliation, as well as in “belonging without faith”.

The article contains reflections on the growing importance of intercultural education in the context of Polish pedagogical literature. Statistics related to the internationalization of the Polish social context are explored. The following scientific journals in Poland and Europe were selected, considered important in the discursive space of social pedagogy and social work: European Journal of Social Work, International Journal of Social Pedagogy, Pedagogika Społeczna quarterly, Pedagogika Społeczna NOVA (Social Education NOVA), Praca Socjalna (Social Work) and the journal Edukacja Międzykulturowa (Intercultural Education). Their content was analyzed in terms of topics in the field of intercultural education with the use of quantitative systematic semantic analysis to establish how many articles (directly related to intercultural education and intercultural context) and in what periods were published in the selected journals. This part of the article is its empirical section, based on desk research of the existing documents. The thesis on the growing importance of intercultural education in the fields of social pedagogy and social work was presented and arguments in support of this thesis were formed.

RESUMO Objetivo: Analisar se houve impacto da pandemia de COVID-19 na prevalência de transtornos mentais comuns (TMCs) entre estudantes de Medicina, investigando os possíveis fatores de risco associados. Métodos: Estudo observacional, desenvolvido com 289 estudantes de Medicina de Salvador, Bahia, realizado antes e durante a pandemia da COVID-19. Utilizou-se um questionário estruturado contendo dados sociodemográficos, acadêmicos e sobre hábitos de vida. O rastreamento de TMC foi realizado por meio do Self-Report Questionnaire (SRQ-20). A coleta de dados ocorreu em duas etapas: a primeira, presencial (período anterior à pandemia) e a segunda, virtual (período pandêmico). Resultados: Não houve diferença na prevalência de TMC entre os momentos antes e durante a pandemia (48,0% vs. 44,5%, p = 0,577). Durante a pandemia, verificou-se aumento do envolvimento religioso (80,6% vs. 92,7%, p = 0,002) e do consumo de bebidas alcoólicas (45,9% vs. 69,1%, p < 0,001). Entre os estudantes, observou-se aumento de TMC entre homens (17,0% vs. 34,1%, p = 0,036); redução entre mulheres (83,0% vs. 65,9%, p = 0,036); aumento entre aqueles com envolvimento religioso (80,9% vs. 92,9%, p = 0,036); e aumento em todos os ciclos acadêmicos (p = 0,039). Conclusão: Apesar de a prevalência de TMC em estudantes de Medicina manter-se expressiva, não foi demonstrado impacto direto da pandemia de COVID-19 em suas taxas. Ademais, a prevalência de TMC foi maior entre os estudantes com engajamento religioso e consumidores de bebida alcoólica.

ABSTRACT Objective: Analyze craving in smokers with cardiovascular comorbidities submitted to a nutritional approach. Methods: Two groups were randomized and submitted to clinical intervention (n = 32): Group 1 (G1, n = 15): ingested 40 g of chocolate containing 70% cocoa/day and behavioral intervention for smoking cessation for one month; Group 2 (G2, n = 17): control group, only behavioral intervention. Questionnaire of Smoking Urges-Brief (QSU-Brief) - Brazil version measured total craving and its factors. Anthropometric measurements verified the nutritional interference of the procedure and the serum assessment verified the interference of inflammatory processes related to smoking. The study was registered on the Brazilian Registry of Clinical Trials (ReBEC): RBR-83jr3. Results: After one month, compared to the initial evaluation, the G1 reduced the craving evaluated by the QSU-Brief and its Factors 1 and 2. Total QSU-Brief: 44.27 ± 15.82 x 27.00 ± 18.03 (p = 0.008); Factor 1: 21.90 ± 7.70 x 12.90 ± 8.87 (p = 0.006); Factor 2: 11.90 ± 6.30 x 7.00 ± 6.63 (0.007). G2 showed a reduction in total QSU-Brief and Factor 1, but not in Factor 2. QSU-Brief total 28.17 ± 17.24 x 19.52 ± 9.50 (p = 0.049); Factor 1: 14.47 ± 8.74 x 9.23 ± 6.11 (p = 0.046). Serum levels of cortisol, leptin, serotonin, C-Reactive Protein (CRP) and insulin did not show differences (p > 0.05). No anthropometric differences were found. Conclusion: The results demonstrate that daily consumption of chocolate for one month (70%) reduced craving in smokers at the beginning of treatment. Chocolate potentiated the well-known effect of behavioral counseling on Factor 1 (pleasurable drug effects) and also interfered with factor 2 (unpleasant withdrawal effects).

ABSTRACT This study aimed to characterize interdisciplinarity within the Bachelor of Interdisciplinary Studies in Science and Technology - BC&T degree at a federal university located in the state of Minas Gerais, based on the proposal of the ‘Guiding References for Interdisciplinary Bachelor’s and Similar’. We are grounded on the works of Lenoir (1998), Japiassu (1976), Coimbra (2000), Fazenda (2010), Fortunato and Confortin (2013), Tosta (2011), Almeida (2010) and Morin (2003). We aimed to check if the course, through its Pedagogical Project and the didactic-pedagogical actions, is in line with the guidelines and principles of the Bachelor of Interdisciplinary Studies - BIs regarding interdisciplinarity. For this, we carried out a qualitative and quantitative study with bibliographic and documental research, and a field study, using questionnaires applied to fifth and sixth-semester students and semi-structured interviews with professors. We found out that, in general, in the context of the course, the interdisciplinary methodology is not adopted as established in BIs’ guidelines and principles. Based on data analysis and supported by the theoretical contribution of the consulted authors, we present some proposals to contribute to the dissemination of interdisciplinarity in the teaching and learning process of BIs. In addition, we aim to contribute to the scientific development of the theme enabling new discussions to ensure the effectiveness of interdisciplinary actions in educational institutions.

Published: November 2023

ABSTRACT: This text aims to analyze the process of professional constitution of the pedagogical coordinators of daycare centers and preschools, based on the social experiences they have lived in Early Childhood Education. The article is conceptually based on the Pedagogies of Childhood and Early Childhood Education (FERNANDES; CAMPOS, 2015; ROCHA, 2001; SILVA, 2008; among others), articulated with the sociology of experience, formulated by François Dubet (1996). From the methodological point of view, the empirical material was produced through document analysis and interviews with six pedagogical coordinators from Turmalina, a city situated in the northern of the State of Minas Gerais, Brazil, and, consecutively, was submitted to content analysis (BARDIN, 1977). The analyzes of this material allowed to verify that they act from different logic of action to become professionals, which affects the construction process of their professionalities. The study highlights the emergence of an epistemological statute that defines the roles due to the pedagogical coordination of daycare centers and preschools, considering the sociopolitical and pedagogical specificities of Early Childhood Education.

Authors: Peixoto Vitor de Moraes , Leal João Gabriel Ribeiro Pessanha , Marques Larissa Martins
Published: November 2023

ABSTRACT The immunization campaign against COVID-19 started in Brazil in January 2021 after strong pressure from society on the federal government, which had created a series of ideological obstacles against vaccines, especially those produced with Chinese inputs. This article analyzes the impact of far-right ideology on the spatial distribution of vaccine coverage against COVID-19 in Brazilian municipalities. By means of hierarchical models, it was identified that, maintaining constant socio-demographic characteristics and the structures of the Unified Health System, the degree of bolsonarismo in the municipalities had a negative impact on the coverage rates of the first, second and, especially, of the third dose.
A philosophical conversation with Lorena Cabnal from Guatemala
Authors: Patiño Niño Diana Milena
Published: November 2023

Abstract: In this paper I want to focus on the feminist Lorena Cabnal from Guatemala. I want to do so through her words in various spaces: videos, conferences, conversations with her, and her writings. My final goal is to engage with Cabnal’s ideas/actions not only as feminist thought, but as philosophical formulations, even though they are not presented as they are usually presented in traditional academia, and they are not formulations involving universal categories. I want to talk with/from the concepts she develops in/with her experience in the same way as we usually engage with concepts formulated by an intellectual recognized as such by academia. My conversation with Cabnal will be grounded in my particular experience as a mestiza woman philosopher from Colombia (Diana Milena PATIÑO, 2021).

Published: November 2023

Resumo O estudo tem por objetivo estremar as relações de poder, dependência e exclusão existentes na Rede Federal de Educação Profissional, Científica e Tecnológica e suas implicações nos níveis de sua organização e nos aspectos das instituições que a compõem. A pesquisa é documental, e seu corpus é formado por documentos oficiais, projetos de lei, leis, relatórios emitidos por órgãos federais, páginas eletrônicas e produções acadêmicas. A lente teórica utilizada, com o uso das categorias estabelecidos e outsiders, é a teoria eliasiana. Constatou-se que as 19 Escolas de Aprendizes Artífices representam a gênese da Rede, que, apesar das tensões, foi ampliada politicamente. O avanço para níveis mais elevados de ensino, materializado em transformações institucionais, tem como ponto de inflexão a Universidade Tecnológica Federal do Paraná. O Ministério da Educação vem propondo políticas para frear o pleito individual dos membros da Rede para níveis mais elevados de ensino. O movimento mais notório nesta direção foi a implantação dos Institutos Federais de Educação, Ciência e Tecnologia. Conclui-se que a Rede, enquanto uma configuração pulsante, foi construída entre o estigma de ofertar uma espécie de ensino de segunda classe, destinada às classes mais desfavorecidas (ÉRGA) e a busca de um status superior (ÉPEA).
Poetry and Oral Collection in the Weaving of Poems of Batata cozida, mingau de cará [Cooked Potato, Yam Porridge] Written by Eloí Bocheco
Authors: Grazioli Fabiano Tadeu
Published: November 2023

ABSTRACT This study observes oral poetry as an aesthetic manifestation and attention, especially to poems that recall childhood in which the inspiration is the oral collection. Coordinates favor following the poetic and creative properties of the aforementioned poetic genre, from which verses from the book Batata cozida, mingau de cará [Cooked Potato, Yam Porridge], written by Eloí Bocheco (2006), are analyzed. Thus, it can be said that the poetics for childhood understood by the writer’s proposal allows the little reader to transit, in the same creation, through the known, that is, throughout the elements of oral poetry almost always recovered from the popular tradition; and for what he knows at the same opportunity: the poem of declared authorship, which presupposes a work woven basically in writing. In addition, such verses can be understood as a variation of the oral tradition, renewed on the threshold between orality and writing, in a playful game with both codes.
Forum: Populist Radical Right & Illiberal Foreign Policymaking
Authors: Salgado Carolina , Casarões Guilherme , Zarakol Ayse
Published: November 2023

Abstract What makes current radical right populists different from other historical radical right leaders of the 20th century? Are there more differences or similarities among populist radical right (PRR) in the Global South regarding how they perform foreign policy? How does the context – marked by contemporary globalization, regional interdependencies and power (geo)politics – influence their perceptions about their own capabilities and interests, but also about the international liberal order, its values and multilateral mechanisms? This forum addresses questions like these, offering theoretical, historical and contextual insights with concrete examples and case studies situated out of the Anglo-American spectrum. Different from traditional approaches to foreign policy analysis, the authors advance reflections about current phenomena such as illiberal foreign policymaking, anti-cosmopolitanism, religious nationalism and its transnational ties, and the re-personalization of sovereignty in the figure of the PRR. Therefore, it enriches the study of populism, radical right and foreign policymaking in IR, bringing to the debate the erosion of the liberal international order and the necessary questioning of Western-led globalization.
SUFRIMIENTO AMOROSO Y SEXO EN EL ROCK PERUANO: ANÁLISIS SEMÁNTICO PRAGMÁTICO
Authors: Linares-Quispe Rafael Angel , Leon Gonzales Alexandra Priscila
Published: November 2023

El rock peruano responde a los contextos económicos, políticos y sociales por los que atraviesa el país, y se conforma como un medio de expresión de la población en general. El objetivo de la investigación fue analizar las representaciones del sufrimiento amoroso y el sexo en las letras de las canciones de Pedro Suárez-Vértiz y Libido. Para ello, se aplicó el enfoque semántico pragmático propuesto por Molero (2003) compuesto por los niveles: lógico-conceptual, lingüístico y discursivo. Se determinó que, a nivel lógico conceptual, en ambos artistas las canciones sobre la congoja amorosa describen situaciones en las que el protagonista sufre por recuerdos o el fin de una relación; mientras que, sobre sexo, se identificó que la lírica describe actos sexuales. A nivel lingüístico, los dominios sobre sufrimiento amoroso en ambos artistas son: inmaterial y sentimientos; sobre sexo, el dominio común en ambos artistas es naturaleza. Por último, a nivel discursivo se identificó que en la letra de ambos artistas y en ambos temas predomina la narración de los hechos: en la lírica de Libido se empleó un lenguaje más literario y presentó un mayor número de metáforas para referirse al sufrimiento amoroso; mientras que la lírica de Suárez-Vértiz empleó un lenguaje más explícito y un mayor número de metáforas para referirse al sexo.
DIFFUSION INTERACTION MODEL IN AL-FE2O3 SYSTEM INCLUDING THE FORMATION OF INTERMETALLIC PHASES
Authors: Anisimova Mariia A. , Knyazeva Anna G.
Published: November 2023

In this paper, we consider the problem of interaction of a spherical iron oxide particle with an aluminum melt surrounding it. A comparison of two different approaches to describing the interaction in the Al-Fe2O3 system suitable for various temperature intervals is presented. The first of these is the problem with the volume reaction. This problem is solved numerically by front straightening method. The counter-sweep method and an implicit difference scheme are used. The second variant of the model corresponds to sequential reactions and is typical for reactive diffusion theory. This is applicable to another temperature interval when intermetallide does not transfer to the melt. This problem is solved in the quasi-stationary approximation. The results show that both models give similar dynamics of the appearance of Al2O3 oxide. Different rates of intermetallide accumulation reflect different reaction mechanisms in different temperature intervals. Both approaches can be applied to describe the process of phase formation in other, more complex systems.
Surfactants: hygiene’s first line of defence against pollution
Authors: Najim Aya A , Radeef Ahmed Y
Published: November 2023

Surfactants are a diverse group of compounds that are widely used in a range of industrial, commercial and household applications. They are amphiphilic molecules that contain both hydrophilic and hydrophobic groups, which allow them to interact with both water and oil. Surfactants have a number of important properties, including the ability to reduce surface tension, emulsify liquids and solubilise hydrophobic compounds. These properties make them valuable in a range of applications, including detergents (hygiene products), cosmetics, pharmaceuticals and agricultural products. However, the widespread use of surfactants has also raised concerns about their environmental impacts. This review provides an overview of the properties and applications of surfactants, as well as their environmental impacts, the different types of surfactants and their properties and uses in different applications and the current understanding of the environmental fate and impacts of surfactants, including their interactions with aquatic organisms, microbial communities and natural ecosystems. Finally, ths study discusses strategies for minimising the environmental impacts of surfactants, including the development of biodegradable and environmentally friendly surfactants.

Published: November 2023

During the route study of plant biodiversity in a specially protected natural area (SPNA) Zakamsky pine forest, located on the territory of Perm, 17 species of alien plants were found. Only 7 alien species penetrated into the forest communities of the Zakamsky forest; only two of them (Acer negundo L. and Amelanchier spicata (Lam.) C. Koch.) had a high rate of occurrence. In the places of mass invasion of these invasive species, the most typical areas of their introduction were visually determined; 18 test sites were established in these areas, where geobotanical descriptions were carried out according to generally accepted methods. The size of the test sites was 10×10 m. Within their boundaries, the species composition of the tiers of the forest ecosystem and the vertical structure are revealed. The crown density of the stand, the total projective coverage (as a percentage) of the ground cover and the projective abundance of individual species were assessed on the Brown-Blank scale and taken into account.. In the studied communities, Acer negundo has a low abundance. Thus, we can draw a general conclusion that poor sandy and sandy loam soils of protected areas are not suitable for its mass invasions. This species, due to its wide ecological plasticity, in such conditions is able to penetrate only into severely disturbed ecotonic communities, but cannot compete with local species in the depths of the Zakamsky Forest stand. More often, Acer negundo is introduced into middle-aged or mixed-age plantings. Amelanchier spicata is more widely distributed in protected areas. Only swampy conditions, as well as high density of undergrowth and brushwood prevent the spread of the species. In North America, the species often grows in pine forests on sandy soils, so in its characteristic habitats it is able to go deep into woodlands and compete there with species of undergrowth (Sorbus aucuparia, Betula pendula, Padus avium, Picea × fennica). Measures preventing the spread of invasive species are proposed.

The article is devoted to study the antibacterial activity of alcoholic and aqueous extracts from the flowers of two varieties of double-feathered cosmea (Cosmos bipinnatus Cav.) – ‘Rosea’ and ‘Dazzler’ in relation to clinical strains of S. aureus II, S. pneumonia UEV-1, E. coli 89, K. rpeimopiae SES 11/02. The conducted studies have shown that the studied extracts, both with respect to gram-positive and gram-negative strains, exhibit bacteriostatic activity. High bacteriostatic activity of extracts No. 5, 11, 12 was detected with respect to S. aureus at a concentration of 0.08 mcg/ml. Extract No. 6 showed antimicrobial action only at high concentrations of 0.96-0.8 mcg/ml. The activity against S. pneumoniae was shown by extract No. 6 in the concentration range of 0.96-0.32 mcg/ml, it was inferior in antibacterial effect to the comparison drug in high dosages. High bacteriostatic activity was detected in extract No. 12, with respect to E. coli, where the degree of growth suppression relative to the control was 70%, which corresponded to the minimum studied concentration (0.02 mcg/ml). The comparison drug was inferior in action to extract No. 12 and demonstrated a comparable effect at a concentration of 128 mcg/ml. In relation to K. pneumoniae, extract No. 12 showed the best result at the lowest concentration of 0.02 mcg/ml, it showed a growth suppression percentage of 60%, which is comparable to the comparison drug ceftriaxone at a concentration of 32 mcg/ml. The leader was an aqueous extract No. 12 obtained from the flowers of the double-feathered cosmea of the Dazzler variety, which showed bacteriostatic activity against gram-positive and gram-negative test cultures. The most intense effect of the studied extracts was shown in relation to gram-negative flora.

The lack of a user identification system and the existence of a variety of ways to obfuscate a transaction on the Bitcoin network is of great interest to attackers and can be used by them to conduct illegal activities. There is a need to develop new methods of cash identification in the Bitcoin network. The purpose of this work is to develop a method of transaction verification in the Bitcoin network to improve the efficiency of the process of identification of illegally obtained funds and their sources. The work solves the following tasks: the development of a method for transaction verification in the Bitcoin network and the development of a decision support system, which includes the proposed method. The article describes each of the stages of the method: collection, aggregation, processing and analysis of information. The information analysis stage proposes a clustering method that takes into account an extended set of empirical rules (heuristics) of transaction analysis, as well as information about Bitcoin network address owners. The scientific novelty lies in increasing the efficiency of the identification process of illegally obtained funds and their sources through a comprehensive analysis of transactions, including the extended collection of information and its subsequent aggregation in the multi-model database of the decision support system. In contrast to existing methods, the reliability of the identification of Bitcoin network subjects is increased through the use of intelligent methods of data analysis. The results of this work will provide an opportunity to develop new and improve existing transaction analysis tools in future research, which will allow more effective identification of funds in the Bitcoin network associated with illegal activities.

Introduction. The suspension of clinical practices in the nursing profession during COVID-19 generated a decrease in the students՚ abilities and skills which made them vulnerable to more frequent to clinical practice stressors and levels of anxiety. Objective. To determine the relation between clinical practice stressors and anxiety levels in nursing students during COVID-19. Method. A descriptive correlational study with convenience sampling was carried out in 169 students enrolled from third to eight semesters in a public university in the city of Saltillo, Coahuila. For the measurement of variables a sociodemographic data card, the KEZKAK Questionnaire in its Spanish version to measure the clinical practice stressors and the Beck Anxiety Inventory were used. Data collection was through a digital link during August-December 2021. Descriptive and inferential statistics were sued through SPSS V.26. Results. 57.4% reported a medium level of stress and 62.7% a low level of anxiety; however, there are stressors from clinical practice that lead to increased anxiety. A statistically significant positive correlation was found between the study variables (r = .411, p#abr#.001). Discussion and conclusion. The challenges in clinical practice experienced during COVID-19 highlight that generations of future nursing professionals face a scenario that is the product of a post-pandemic era, so it is necessary to strengthen their knowledge and confidence to motivate them to feel safe within the hospital context.

A directional telescopic microphone is composed of two parts. One is the pick-up circuit made up of 34 different length aluminum tubes to respond in a specific frequency. The use of a sensitive FET mic is to pick up a sound from a direction. The signal from the FET mic will be feed to the microphone preamplifier in order to amplify the signal. The Equalization and Attenuation circuit is responsible for the balancing and boosting the low and high frequency. The pick-up signal can be easily recordedto a device through the recording unit or can be heard through the speaker, driven by a power amplifier in order to set up the signal. The main purpose of the gadget is to be used in an environmental study. This can pick up sound that was not normally heard by human ear in a specify distance.
