Authors: Vysochan O. , Hyk V. , Vysochan O. , Yasinska A.
Published: October 2021

Abstract. The necessity of development of the conceptual basis of formation of the accounting information in strategic management of IT-cluster is substantiated. On the basis of the system approach the concept of the account is formed: the place of the account in information system of strategic management is defined; specified and structured basic elements (purpose, tasks, functions, subjects, methods, tools), which form the methodological basis of modern management accounting theory. The study of the structure of strategic management was conducted on the example of the Lviv cluster of information technology and business services (Lviv IT-cluster), which operates as an association of IT companies, Lviv City Council and educational institutions. It is established that the object of management is the joint activities of independent interacting economic entities, each of which in an integrated structure performs its functions. It is established that strategic management accounting provides coordination of interaction of its participants and serves as an information base for development of long-term strategy of development in IT-cluster. It is determined that the introduction of strategic management accounting in the cluster will solve the problem of forecasting and planning the activities of the association as a whole and its individual members. The list of methods and tools of strategic management accounting in the cluster grouped by the authors allows to consider this accounting system not only as an information source of decision-making, but as a tool resource for strategy support. It is determined that the key tools of management accounting in the IT-cluster are SWOT-analysis, a system of balanced scores, benchmarking and budgeting.
Keywords: management accounting, strategy, integrated structures, cluster.

Published: October 2021

Abstract. Public administration should be considered as a certain influence on the part of state authorities and local self-government on the vital activity of individual regions and organizations in order to create a favorable economic environment. Today there is an urgent need for the development of the public administration system, which acts as a powerful mechanism in the state apparatus in order to promote economic development and growth. But like any other control system, it is influenced by both factors and factors that can always have positive consequences. The current conditions that have developed in the world have significantly stopped economic growth and only contributed to its destructuring. Ukraine is no exception in this situation and has a number of problems that in one way or another have a negative impact on the public administration system for economic development. The aim of our research is to form a methodological approach to the definition and compilation of the main factors of influence on the public administration system of economic development. During the research, we used the methods of expert assessment to determine the main factors of influence on the public administration system of economic development and the modeling methodology for the hierarchical ordering of these factors according to the application of graph theory. As a result of the study, we presented a methodological approach to determining and compiling the main factors of influence on the public administration system of economic development, which, unlike the existing ones, provides for the use of the expert assessment method and modeling methodology for the hierarchical ordering of these factors according to the application of graph theory. Our research can have a practical aspect of application in public authorities. The research has limitations, which can be traced in the fact that only the economic environment of Ukraine was used as an object of research and in subsequent research, attention should be focused on the international level.

MODELLING THE SECURITY OF BUSINESS PROCESSES WHEN CREATING AND TRANSFERRING VALUES FOR STAKEHOLDERS
Authors: Krasnokutska N. , Koptieva H.
Published: October 2021

Abstract.The purposeof the recent study is to substantiate the directions and develop a methodological approach to modelling the security of business processes by their main types, considering the interests of stakeholders who receive value from interaction with the business.Business as an economic system is based on the significant number of transactions that can lead to different financial, material, informational losses, as well as reputational risks due to the lack of stakeholders’ trust. To prevent these losses when creating and transferring values for stakeholders we suggested the approach to modelling the security of business processes which takes into account their main types (main, auxiliary, managerial business processes and business development processes), the results (value created) that key stakeholders get at the output of these processes, and the indicators that reflect the criteria for modelling the security of business processes — efficiency, effectiveness, and quality (customer satisfaction with the result of the process — the recipient of value). Using the fuzzy set method, a map of identification of the security status of basic, auxiliary, managerial business processes and business development processes was developed, which allows to use a wide range of characteristics of business processes and linguistic variables to describe them (from «catastrophic» state to «very good») and allows you to model options for changing the strategy of the enterprise in order to avoid the risk of imbalance of economic, social and environmental interests of its stakeholders.
The proposed approach was applied to retail chains in Ukraine and provided decision-makers with useful information for a better contribution of internal control systems to creating stakeholders’ value.

Published: October 2021

Анотація. Заощадження населення є вагомим внутрішнім джерелом інвестиційного потенціалу держави, завдяки якому формується національний добробут розвинутих країн. Інвестиційний потенціал домогосподарства запропоновано розглядати з позицій їхніх можливостей здійснювати заощадження, схильності до ощадливості та намірів трансформувати неспоживчі ресурси в інвестиційні.
Проведений аналіз динаміки доходів і витрат, депозитів і внесків до недержавних пенсійних фондів населення України у 2010—2020 рр. дав змогу виявити обмеження у формуванні та ефективному використанні інвестиційного потенціалу домогосподарств: низький рівень оплати найманої праці та брак фінансових ресурсів у домогосподарств для формування їхнього інвестиційного потенціалу; збереження значних заощаджень домогосподарств поза межами фінансової системи; слабкий розвиток ринків цінних паперів і небанківських фінансових послуг, недостатній рівень охоплення ними населення; низький рівень довіри до фінансових інститутів; несформованість у населення ментальності інвестора вітчизняної економіки.
Розроблено підхід до стимулювання участі населення в інвестиційному процесі, який передбачає акумулювання домогосподарствами власних заощаджень на спеціальних рахунках, відкритих у банках із подальшим спрямуванням цих коштів в інвестиційні та інноваційні проєкти, які реалізуються в тих галузях економіки, що мають стратегічне і пріоритетне значення для соціально-економічного розвитку національної економіки. Обґрунтовано механізм створення та функціонування Фонду компенсування інвестицій фізичних осіб, призначеного для відшкодування збитків, заподіяних професійними інвесторами. Для підвищення активності домогосподарств підтримувати соціальні проєкти запропоновано заходи з популяризації ідеї створення ендавмент-фондів серед вітчизняних некомерційних організації та підвищення їхньої привабливості перед потенційними інвесторами і партнерами.
Сформульовано пріоритети державної політики активізації інвестиційного потенціалу домогосподарств в Україні: забезпечення умов для розширення інвестиційного потенціалу домогосподарств за рахунок зростання реальних доходів населення; розроблення комплексу заходів для забезпечення гарантій для участі домогосподарств в інвестиційних процесах; створення ефективної системи залучення заощаджень домогосподарств в інвестиційну діяльність за допомогою широкого спектра надійних і зрозумілих для пересічного громадянина фінансових механізмів; підвищення рівня фінансової грамотності українців у контексті активного їх залучення до інвестиційних процесів на фінансовому ринку; відновлення довіри населення до національної валюти і діяльності фінансових посередників.
Ключові слова: домогосподарства, інвестиції, інвестиційний потенціал, заощадження, механізм трансформації заощаджень.

Анотація. Метою дослідження є оцінка фінансових та інвестиційних детермінант розвитку українських регіонів в умовах економічної нестабільності, зумовленої пандемією COVID-19. Проаналізовано вплив рестриктивних і стимулювальних інструментів державної політики на національному і регіональному рівнях на сучасний стан регіональних економічних систем, зокрема в контексті таких складових, як стабільність цін, залучення інвестицій, поліпшення ділового клімату, кредитування, капіталовкладення, прозорість адміністрування бюджетоутворюючих податків і стабільність державних фінансів. Цісекторинайбільшчутливі до заходівдержавноїполітики, особливо в умовах суспільної турбулентності.
Аналіз фінансових детермінант регіонального розвитку в умовах короновірусної кризи сприяв окресленню таких негативних тенденцій: значне падіння інвестицій в економіку регіонів і зниження частки нових інвестиційних проєктів є найбільш негативними наслідками, які суттєво вплинуть на темпи економічного зростання в наступні періоди; погіршення ділового клімату, падіння обсягів позик, що надаються суб’єктам господарювання, і зростання частки короткострокових позик вплинули на нові інвестиційні рішення; невиконання запланованих показників податкових доходів місцевих бюджетів (ПДФО, місцеві податки), вплинуло на обсяги доходів місцевих бюджетів, включаючи інвестиційні; зменшення трансфертів до місцевих бюджетів від державного вплинуло на фінансування програм регіонального розвитку; відплив іноземного капіталу, який відбувся не лише через погіршення ділового клімату в країні, а й унаслідок впливу психолого-емоційних факторів поведінки інвесторів в умовах невизначеності.
Економічні, фіскальні та соціальні наслідки COVID-19 територіально диференційовані. Різніризики пандемії багато в чому зумовлені економічними та просторовими особливостями регіонального розвитку. Водночас паніка, спричинена поширенням COVID-19, що призвела до ухвалення низки нераціональних рішень фінансово-економічними суб’єктами на різних рівнях управління, є важливою причиною загострення визначених проблем. Значне зменшення інвестицій в економіку регіонів і падіння частки нових інвестиційних проєктів є найбільш негативними наслідками, які суттєво вплинуть на темпи економічного зростання в наступні періоди.

DISTRIBUTION OF BLOOD COMPONENTS ALONG THE CROSS-SECTION OF THE VASCULAR DEPENDING ON THE CONCENTRATION OF ERYTHROCYTES
Authors: Fedoseev Victor B.
Published: October 2021

The dependence of the stationary distribution of blood components over the cross section of the cylindrical Poiseuille flow on the content of erythrocytes is described by the method of numerical simulation. A thermodynamic approach was used, in which dispersed phases are represented by a set of cellular components (erythrocytes, leukocytes, platelets), and blood plasma is considered as a low molecular weight dispersion medium. The simulation is based on the search for the minimum of the total energy of the system, including the chemical potentials and kinetic energy of all components. This state corresponds to the only solution describing the consistent distributions of all components of the multiphase flow over the section. Distributions of components were simulated, in which the content of leukocytes and platelets corresponds to the normal, for cases of normal, pathologically low (erythropenia) and high (erythrocytosis) content of erythrocytes. As an example, the Poiseuille flow in a vessel 1 mm in diameter with a shear rate of 10 s -1 is considered. According to the simulation results, the deviation of the number of erythrocytes from the norm leads to redistribution over the cross section of the flow of other components (leukocytes and platelets). The concentration of platelets and leukocytes has maximum values in the vicinity of the vessel walls with a low number of erythrocytes. When the number of red blood cells increases, maxima concentration of platelets and white blood cells are shifted to the center of the vessel and the proportion of red blood cells near the vessel walls increases

Published: October 2021

Allergic asthma is a complicated respiratory problem characterized by airway inflammation, airway hyperresponsiveness (AHR), breathlessness, mucus hyper-secretion, and goblet cell hyperplasia. Asthma is controlled by genetic and environmental factors. Allergy is the main trigger of asthma and is mediated by Th2 cytokines along with IgE production. Vitamin D (Vit D) is the main supplementary factor for the immune system. In the present study, we investigated the effect of Vit D on the exacerbation of allergic asthma.
A murine model of allergic asthma was induced by ovalbumin (OVA) in four of five groups of studied female BALB/c mice (each group, n=20). One group was considered as control. Of OVA-induced mice, two groups received Vit D via oral (10,000 IU/kg diet) or intranasal (inhalation) forms (30 min on days 25, 27, and 29), and the third group received budesonide. At least, AHR, the levels of IL-4, IL-5, IL-13, and INF-g in bronchoalveolar lavage fluid (BALF), serum IgE and histamine, IL-25 and IL-33 gene expression, as well as histopathology study of the lung were done.
The Penh values, type2 Cytokines in BALF (in both protein and molecular levels), total IgE and histamine, perivascular and peribronchial inflammation, goblet cell hyperplasia, and mucus hypersecretion decreased significantly in both oral and intranasal Vit D-treated asthmatic mice groups, especially on day 38 of orally treated mice.
Here, we found Vit D as a promising agent in control of allergic asthma with a remarkable ability to decrease the severity of inflammation. Therefore, Vit D sufficiency is highly recommended in asthmatic patients.

More than 99% of cervical cancers are associated with human papillomaviruses (HPVs) worldwide. Current HPV vaccines are safe, highly immunogenic, with effective immunity against specific HPV types. However, DNA vaccines are a new appealing platform which can be considered for designing the HPV vaccines. This study aimed to construct a recombinant eukaryotic expression plasmid containing L1 of HPV-18, tissue plasminogen activators (tPA), and pan HLA DR-binding epitope (PADRE) genes into the pVAX1 vector.
The L1, tPA, and PADRE genes were amplified in a thermocycler. The polymerase chain reaction (PCR) products were cloned and insertion of the genes was confirmed using colony PCR, restriction enzymes analysis, and sequencing methods. Indirect immunofluorescence, RT-PCR, and western blot assays were applied to identify the target gene in HEK-293 cells. Total IgG and its isotypes in immunized mice were measured by enzyme-linked immunosorbent assay technique.
Western blot analysis showed a protein band of about 67.5 kDa in supernatant and cell lysate of transfected cells. The results of mice immunization with different constructs (group 1: the pVAX-L1, group 2: pVAX-tPA-PADRE-L1, group 3: pVAX1, and group 4: PBS as controls) indicated that the pVAX1-tPA-PADRE-L1 construct induced a significantly higher level of total IgG than pVAX1-L1 (p=0.003).
In conclusion, pVAX1-tPA-PADRE-L1 recombinant plasmid is a highly immunogenic construct and suggests as a promising candidate for vaccine development against HPV type 18 in low-middle-income countries.
Study of the Effects of N-acetylcysteine on Inflammatory Biomarkers and Disease Activity Score in Patients with Rheumatoid Arthritis

Published: October 2021

Rheumatoid arthritis (RA) is considered as an autoimmune-related condition in which the overproduction of pro-inflammatory cytokines leads to an inflammatory cascade. N-acetylcysteine (NAC) is a potent anti-inflammatory and anti-oxidant agent. We aimed to explore the impact of oral NAC on cytokines activities and clinical indicators in RA patients.
In this placebo-controlled randomized double-blind clinical trial, 41 active RA patients were allocated in either NAC (600 mg, twice a day) or placebo group, as add-on therapy to the routine regimen, for 8 weeks. Disease activity score with an erythrocyte sedimentation rate (DAS28-ESR), and serum concentrations of interleukin (IL)-1β and IL-17 were assessed at baseline and end of the trial for all participants in the test and control groups.
The reduction of the DAS28-ESR was higher considerably in the NAC group compared to that of the control group. No statistically significant differences were seen in the reduction of IL- 1β and IL-17 cytokines between the NAC and control groups. In addition, improvements in the patient global assessment, number of tender joints, number of swollen joints, and the ESR rates were in favor of the NAC group.
Our findings reveal that NAC may have a beneficial effect on all of the clinical features of RA. However, non-significant variations in the IL-1β and IL-17 levels suggest an alternative way of NAC effectiveness without influencing the measured cytokines. Nevertheless, these results need to be confirmed by further investigations.

Published: October 2021

Food protein-induced enterocolitis syndrome (FPIES), is a non-IgE mediated food allergy presenting in infants younger than 12 months. Diagnostic delay may occur due to overlapping clinical symptoms with several conditions. Here, we present two cases of FPIES, mistakenly diagnosed and treated as Bartter syndrome. This study aims to emphasize the several features of this syndrome that may mimic other diagnoses and sometimes leading to near-death events due to delay in the diagnosis and improper treatment. The first patient was a 30-month-old boy with multiple episodes of profuse vomiting and diarrhea within 1 hour after breastfeeding, beginning from the first month of life progressing to hypokalemia and metabolic alkalosis at the age of 5 months leading to the diagnosis of Bartter syndrome. The second patient had a history of unremitting diarrhea which had been started soon after his first breastfeeding followed by biliary vomiting on the 7th day of life. He was treated in another hospital for neonatal sepsis, however, without an appropriate response to treatment. To conclude, despite the current belief on the rarity of FPIES, it is a more prevalent disease than expected with various non-specific manifestations imitating other conditions which may result in diagnostic delay and sometimes fatalities. To shed light on the importance of the physicians’ awareness of this syndrome, these two cases are presented here as examples of FPIES imitating other disorders.
Reciclagem de resíduos químicos na fabricação de placas de circuito impresso: relato de um projeto de pesquisa acadêmico (Programa de Iniciação Científica Voluntária)
Authors: Nunes Maíra de Paula , Siqueira Antonio Marcos de Oliveira
Published: October 2021

Propõe-se neste artigo um método de recuperação de uma solução de cloreto férrico, que, após uso constante para corrosão de placas de circuito impresso, produz uma solução corrosiva contendo cobre. Esse processo de corrosão de placas é bastante comum na área da eletrônica, sendo realizado nos laboratórios e no ambiente doméstico, em decorrência disso, é descartado inadequadamente na rede de esgoto. O estudante de engenharia tem em vista o método mais eficaz, porém, o que menos impacta no meio ambiente ao estudar um processo. Assim, este estudo proporciona um crescimento profissional do graduando de engenharia ao reciclar a solução de cloreto férrico, que o descarte inapropriado danifica o sistema de esgoto e gera prejuízos à saúde humana e ao meio ambiente, e reduziria gastos na instituição, onde a solução é usada nos laboratórios do Departamento de Engenharia Elétrica e seria tratada por uma empresa terceirizada ao fim de sua vida útil. Ao apresentar três métodos de recuperação, o projeto estuda qual método é o mais eficiente e oferece menos riscos ao operador, visto que esses métodos são realizados, também, em ambiente doméstico. Os testes realizados com as soluções recuperadas a partir dos métodos apresentados permitem a comparação e o entendimento da importância de cada etapa dos processos de recuperação, desse modo, é possível propor um novo método sintetizando as etapas dos outros processos que realmente importam na reciclagem da solução e que permita a recuperação do cobre em solução para outros estudos, como agregar valor a esse resíduo, possivelmente aumentando a vida útil da solução reciclada. O novo método pode ser realizado em ambiente doméstico, pois utiliza materiais de fácil acesso e não oferecem grandes riscos aos operadores. No laboratório, utilizando materiais com um nível de pureza maior e em altas concentrações, é possível obter uma corrosão mais eficiente e absorver a produção de solução desgastada de percloreto dos laboratórios do Departamento de Engenharia Elétrica da instituição.
Desert Locust Schistocerca gregaria Forskål (Acrididae): Biology, Management and Strategies: A Review
Authors: Rajak Dinesh Chandra , Yadav Jyoti
Published: October 2021

Early 2020 witnessed the emergence of global agrarian crisis with the widespread burgeoning of destructive migratory pest, Desert Locust (Schistocerca gregaria) in East Africa, Southwest Asia, Pakistan and India. Characterised by the ability to eat ravenously, breed exponentially and migrate rapidly; locust swarms has led to substantial agrarian disaster. The current official strategy is to control the upsurges to evade plague. Though it may seem attractive and efficient, it is sensible only if the numbers are relatively low. The socio-economic and environmental challenges posed by the unprecedented locust outbreak has prompt the scientists worldwide to emanate an effective preventive management strategies that rely on updated knowledge of pest biology, ecology and behaviour along with efficient monitoring, data management, analysis, forecasting, resource deployment and control techniques. In addition, the integrated network of field teams, decision makers, analysts, rural governing bodies and farmers potentially offers better compliance of pest management strategies.
Imagens do canibalismo na primeira modernidade
Authors: Berbara Maria
Published: October 2021

Em ilustrações de livros, gravuras e mapas europeus produzidos na primeira época moderna é comum representar o canibalismo através de mesas de abate sobre as quais seres humanos são desmembrados. Este artigo investiga os meandros globais percorridos pela mesa de açougueiro, ou de abate, antes de ser firmemente incorporada à iconografia do “canibalismo brasileiro”. Importantes precedentes são, de um lado, elementos retóricos e visuais remontantes à antropofagia mongol; de outro, a iconografia da profanação da hóstia e o conceito da contrafação do sagrado.
A "virada global" como um futuro disciplinar para a História da Arte
Authors: Tatsch Flavia Galli , Farago Claire
Published: October 2021

As discussões sobre a "virada global" na História da Arte estão ganhando cada vez mais espaço. Desde o final do século passado, os historiadores da arte voltaram seus procedimentos e métodos para aprofundar as conexões, trocas, interdependências, mobilidade e culturas visuais compartilhadas entre grupos geograficamente diversos. As pesquisas realizadas nesse contexto abriram novos caminhos para materialidades, obras e objetos pouco estudados ou conhecidos. É cada vez mais necessário incentivar a pesquisa que conecte as várias regiões e formas culturais. Como os insights de estudos regionais e locais podem ser integrados em uma rede internacional inclusiva de atividades acadêmicas? Convidamos propostas teóricas criativas e estudos de caso estratégicos de todos os campos, locais e épocas para prever um futuro para a história da arte global, concentrando-nos em conectividades, diferenças culturais negociadas e processos históricos dinâmicos. Esse futuro disciplinar resiste à lógica da globalização econômica, evita o enquadramento nacional de seus objetos de investigação, evita hierarquias de gênero, rejeita o presentismo histórico e põe em causa reivindicações não examinadas de universalidade.
Pressing “rewind” and “forward” to negotiate a transcultural position
Authors: Koch Franziska
Published: October 2021

The transcultural artistic strategies formulated in the Fluxus network during the 1960s, spanning Europe, East Asia, and the USA, are an important reference when searching for ways how to write art history in a global way. These strategies challenged national framings of art informed by the Eurocentric legacy of modernism. In this paper, I focus on Nam June Paik’s (self)positioning in negotiation with the taxonomic mechanisms of the Guggenheim Museum New York in 1994. I will analyze the conditions and limits of his cultural mediation. The first part of my chapter shows how Paik drew a fine-grained picture of Japanese experimental art as a Korean who had studied in Tokyo during the 1950s and then re-visited in the 1960s. In his version, Paik employs transcultural discursive strategies directed towards rewriting art history in ways that take account of multiple agencies and cultural entanglements. The second part of my study analyzes the resulting institutional conflict between Paik and Guggenheim’s Japanese survey show, Scream against the sky, to which he contributed an essay but declined to participate with his work. This paper articulates the transcultural (counter-) potential of artists who work(ed) across borders, especially at moments when Western canonization was a double-edged sword.

Características clínico-epidemiológicas del Síndrome de Guillain Barré en tres hospitales de Piura, 2018-2019
Authors: Solano Fiorela E.
Published: October 2021

El síndrome de Guillain-Barré (SGB) es una polirradiculoneuropatía inflamatoria aguda con presentaciones clínicas diversas clasificadas como variantes clínicas, sobre las cuales se tiene escasa infomación en nuestra región. Objetivo: Determinar las características epidemiológicas y variantes clínicas del SGB. Material y Métodos: Estudio descriptivo transversal retrospectivo. Se revisaron las historias clínicas de los casos sospechosos de SGB en tres hospitales de Piura, entre 2018-2019. Se incluyeron todos los casos sin límite de edad, excluyéndose únicamente aquellos con duda diagnóstica o historias incompletas. Los datos se analizaron mediante STATA vs 15.0. Resultados: De 123 casos, 61% fueron varones, con una edad promedio de 37 años. El 36,59% de los casos no presentaban antecedentes clínicos. La comorbilidad más frecuente fue Hipertensión Arterial (HTA). Sólo 40% de los casos fueron confirmados. El 78% se trató con inmunoglobulina. La variante más frecuente fue Poliradiculopatía Desmielinizante Inflamatoria Aguda (AIDP, sigla en inglés). Conclusiones: El SGB se presentó con mayor frecuencia en el sexo masculino y la forma clásica fue la variante más frecuente seguida de la regional. La mayoría de casos fueron clasificados como leves, con un grado promedio de discapacidad de 3. Se recomiendan estudios sobre la asociación entre cada variante clínica y las características clínicas de la enfermedad.
Aspectos subjetivos de la hipocondría
Authors: García-Arroyo José Manuel
Published: October 2021

Objetivos: Se intenta esclarecer los aspectos subjetivos de la hipocondría (o hipocondriasis), no suficientemente consistentes en las publicaciones sobre el tema, vacío que parece deberse a que actualmente se consideran únicamente las manifestaciones externas (conductuales) del paciente, prescindiendo de aspectos más personales. Material y Métodos: Se incluyen 12 pacientes diagnosticados de hipocondría (CIE-10) que acudieron a consulta en la Asociación de Psicopatología y Psicoanálisis de Sevilla (APPS) y a los que se aplicó el Método de Abordaje de la Subjetividad (MAS). Al expresarse verbalmente en las entrevistas, los pacientes descomponen analíticamente el problema que los aqueja, en distintos elementos; los enunciados así obtenidos se agrupan en categorías que definen los componentes subjetivos buscados. Resultados: Los hallazgos incluyen la exagerada intensidad con que los pacientes experimentan las sensaciones físicas, la anómala dirección de la atención y la atribución de significados erróneos, elementos que, al interactuar, forman un “bucle” o nudo del que les es imposible escapar. La utilización del -cuadrado de Apuleyo- ha contribuido a visualizar cómo los sujetos afectados mantienen el cuerpo por encima de todo, de manera que todos los vectores convergen necesariamente en él; ello explica que no puedan acceder a un encuentro auténtico con los demás, sufriendo entonces cierto deterioro social. Conclusiones: Las claves subjetivas aquí diseñadas puedan orientar adecuadamente a profesionales de la Salud Mental que utilicen enfoques psicoterapéuticos en el tratamiento de pacientes hipocondríacos.

Published: October 2021

Operation of an electric drive with damages in power electric circuit of the motor stator results in asymmetry

of the motor phase current charge, increase of heating losses in certain phases, occurrence of variable components of electromagnetic torque and consumed power. An electric motor stator winding consists of a number of stator bars and overhang connections. Due to the complicated winding structure and the steel core, the attenuation and distortion of a pulse transmitted through the winding are complicated, and frequency-dependent. A low voltage impulse method and digital analysis techniques to determine the frequency characteristics of the winding are described. The frequency characteristics of electric motor stator windings are discussed in some detail. The analysis presented in this chapter could be applied to other rotating machines such as low voltage motors. An experiment of damping of electric motor wilding was conducted. Changes in frequency characteristics after the cycle are shown. In this article an analysis of the frequency characteristics of low-voltage electric machines with mush-wound windings, taking into account the processes of successive destruction of the insulation structure by the influence of heat-wet cycles. It is shown that the frequency characteristics can be generalized by the parameter of the state of isolation in the conditions of periodic monitoring of the quality of insulation during regulatory audits. It is proved that the frequency characteristics taken in idle and short-circuit modes have diagnostic features of the level of insulation destruction during humidification, which consist of shifting the characteristics of extremes into the region of lower frequencies, as well as reducing the area under the curve between the minimum and maximum extrema of the characteristic.

Published: October 2021

The main differences in pricing and tariffing for industrial consumers of electricity with different forms of electricity metering are considered. Based on the analysis of tariff formation for the final consumer of electricity, components are identified that have a significant impact on the results of solving the problem of assessing the feasibility of the consumer's transition to hourly electricity metering. Such components include the cost of purchasing electricity in the market segment "day ahead" and the cost of accrued imbalances. The relative daily profile of electricity consumption is considered in order to study the influence of the features of the daily load schedule on the weighted average daily market price of electricity. The importance of estimating the cost of daily load profiles when comparing the cost of electricity for the consumer in the group with integrated electricity metering and in terms of individual hourly metering is substantiated. The effect of underestimation of volumes and value of imbalances in the group with integrated electricity metering in comparison with hourly accruals of volumes and value of imbalances is theoretically substantiated. The main components for comparative assessment of the expediency of the consumer's exit from the group with integrated metering of electricity and the transition to its hourly metering according to the individual daily load schedule are identified. Mathematical models for comparative calculations are developed. The use of these models allows to make an economically justified decision on the expediency of the consumer leaving the group without hourly metering of electricity to the model of purchasing electricity with hourly metering. The main approaches to such an assessment are demonstrated on the example of calculations for an industrial enterprise in some regions of Ukraine. Bibl. 15, fig. 3.

MATHEMATICAL PENDULUM MODEL WITH MOBILE SUSPENSION POINT
Authors: Legeza Viktor P.
Published: October 2021

Background. The new dynamic problem, which is posed and solved in this article, is a theoretical generalization of the well-known classical problem of free oscillations of a mathematical pendulum. In the proposed setting, it is new and relevant, and can be successfully used in such fields of technology as vibration protection, vibration isolation and seismic protection of high-rise flexible structures, long power lines, long-span bridges and other large-sized supporting objects.
Objective. The aim of the work is to derive the equations of own oscillations of a new mathematical pendulum-absorber, to find a formula for determining the frequency of its small own oscillations and to establish those control parameters that allow you to tune the single-mass pendulum absorber to the frequency of the fundamental tone of the carrier object.
Methods. To achieve this goal, we used the methods of analytical mechanics, namely, the Appel’s formalism, as well as the linearization of the obtained differential equations.
Results. A mathematical model is constructed in the work that describes the own oscillations of a new-design mathematical pendulum with a movable (spring-loaded) suspension point with length L. The model is a system of differential equations obtained using the Appel’s formalism. Based on them, after linearization of nonlinear equations, a formula is established for the frequency of small own oscillations of a pendulum with a mobile suspension point.
Conclusions. It is shown that the frequency of own oscillations of the new mathematical pendulum coincides with the frequency of own oscillations of the classical mathematical pendulum with an equivalent suspension length, which is equal to . In the case where the suspension point is fixed (k ® ¥), the frequency formula turns into a well-known formula for the frequency of small own oscillations of a classical mathematical pendulum . If the stiffness coefficient of elastic elements tends to zero (k ® 0), then the frequency w of the damper also tends to zero. An important structural feature of the proposed pendulum is noted, consisting in the fact that due to the appropriate choice of the three control parameters of the pendulum (k, L, m), its frequency in magnitude can be made any in the range from zero to .

The authors evaluated the possibility of using the luminometry method which allows checking the level of sanitation and hygiene in industries and is one of the most effective methods of «rapid microbiology». Such key stages of development of reference material for sodium adenosine triphosphate with the certified values as analysis of similar reference materials, selection of source material of the reference material, conducting experimental studies, and establishing the metrological characteristics of reference material with traceability to state primary measurement standard were provided in the paper. Considering that the selective optical density at the characteristic wavelength is directly proportional to the concentration of the absorbing component (sodium adenosine triphosphate), the stability of R M was studied by spectrophotometry. The stability of the RM material to assess the uncertainty of the measurement results was carried out by the isochronous method. The result of the study is the possibility of ensuring the traceability of measurement results based on luminescence to primary measurement standard by sodium adenosine triphosphate concentration. In addition to the above, the authors selected the optimal value of that concentration and established metrological properties for GSO 11606-2020 R M for the composition of sodium adenosine triphosphate aqueous solution (mass concentration: from 0,09 to 0,11 g/dm3; extended uncertainty: 0,015 g/dm3). Usage of this CRM in performing tests, calibrations, and verification of measuring instruments allows providing the unbiased assessment of the measuring capabilities of luminescent measuring instruments, including in terms of determining the error of the measurements carried out.
