Published: April 2024

Context. Currently, distributed real-time control systems need the creation of devices that perform online computing operations close to the sensor. The proposed online-computers of elementary mathematical functions can be used as components for the functional conversion of signals in the form of pulse streams received from measuring sensors with frequency output.

Objective. The objective of the study is the development of mathematical, architectural and automata models for the design of bit-stream online-computers of elementary mathematical functions in order to create a unified approach to their design, due to which the accuracy of calculating functions can be increased, functional capabilities expanded, hardware costs reduced, and design efficiency increased.

Method. Mathematical models of devices were developed using the method of forming increments of ascending step functions based on inverse functions with minimization of calculation error. Automata models of online-computers based on Moore’s Finite State Machine have been developed, the graph diagrams of which made it possible to ensure the clarity of function implementation algorithms, to increase visibility and invariance of implementation in formal languages of programming and hardware description.

Results. The paper presents the results of research, development and practical approbation of design models of bit-stream onlinecomputers of power functions and root extraction function. A generalized architecture of an online-computer was proposed.

Conclusions. The considered functional online-computers are effective from the point of view of calculation accuracy, simplicity of technical implementation, and universality of the architecture
EVALUATION OF THE INFLUENCE OF ENVIRONMENTAL FACTORS AND COGNITIVE PARAMETERS ON THE DECISION-MAKING PROCESS IN HUMAN-MACHINE SYSTEMS OF CRITICAL APPLICATION
Authors: Perederyi V. I. , Borchik E. Y. , Zosimov V. V. , Bulgakova O. S.
Published: April 2024

Context. A feature of human-machine systems of critical application operating in real time is that they include as elements both technical systems and people interacting with these systems. At the same time, the main difficulties are associated not only with the improvement of hardware and software, but also with the insufficient development of methods for reliably predicting the impact of the production environment on the human factor and, as a result, on the relevance of decisions made by decision makers. As a result, the task of developing methods for determining the mutual influence of environmental factors and cognitive parameters of decision makers on the decision-making process becomes very relevant.

Objective. The aim of the work is to propose methodological foundations for the development and study of fuzzy hierarchical relational cognitive models to determine the influence of environmental factors and cognitive parameters of decision makers on the DMP.

Method. When building FHRCM methods of “soft computing”, methodologies of cognitive and fuzzy cognitive modeling were used, providing an acceptable formalization uncertainty of mutual influence of factors on the DMP.

Results. A fuzzy cognitive model based on a fuzzy Bayesian belief network has been developed, which makes it possible to draw a connection between qualitative and quantitative assessments of mutually influencing factors on the DMP. The proposed model makes it possible to probabilistically predict the influence of factors and choose rational ways of their interaction in the DMP.

Conclusions. The results of the experiments make it possible to recommend using the developed model, which takes into account the mutual influence of factors of various nature, including cognitive ones, in the DMP in order to improve the efficiency of HMSCA management as a whole.
A NONLINEAR REGRESSION MODEL FOR EARLY LOC ESTIMATION OF OPEN-SOURCE KOTLIN-BASED APPLICATIONS
Authors: Prykhodko S. B. , Prykhodko N. V. , Koltsov A. V.
Published: April 2024

Context. The early lines of code (LOC) estimation in software projects holds significant importance, as it directly influences the prediction of development effort, covering a spectrum of different programming languages, and open-source Kotlin-based applications in particular. The object of the study is the process of early LOC estimation of open-source Kotlin-based apps. The subject of the study is the nonlinear regression models for early LOC estimation of open-source Kotlin-based apps.
Objective. The goal of the work is to build the nonlinear regression model with three predictors for early LOC estimation of open-source Kotlin-based apps based on the Box-Cox four-variate normalizing transformation to increase the confidence in early LOC estimation of these apps.
Method. For early LOC estimation in open-source Kotlin-based apps, the model, confidence, and prediction intervals of nonlinear regression were constructed using the Box-Cox four-variate normalizing transformation and specialized techniques. These techniques, relying on multiple nonlinear regression analyses incorporating multivariate normalizing transformations, account for the dependencies between variables in non-Gaussian data scenarios. As a result, this method tends to reduce the mean magnitude of relative error (MMRE) and narrow confidence and prediction intervals compared to models utilizing univariate normalizing transformations.
Results. An analysis has been carried out to compare the constructed model with nonlinear regression models employing decimal logarithm and Box-Cox univariate transformation.
Conclusions. The nonlinear regression model with three predictors for early LOC estimation of open-source Kotlin-based apps is constructed using the Box-Cox four-variate transformation. Compared to the other nonlinear regression models, this model demonstrates a larger multiple coefficient of determination, a smaller value of the MMRE, and narrower confidence and prediction intervals. The prospects for further research may include the application of other data sets to construct the nonlinear regression model for early LOC estimation of open-source Kotlin-based apps for other restrictions on predictors.
REFINEMENT AND ACCURACY CONTROL OF THE SOLUTION METHOD FOR THE DURABILITY PROBLEM OF A CORRODING STRUCTURE USING NEURAL NETWORK
Authors: Brychkovskyi O. D.
Published: April 2024

Context. The prediction of the time until failure of corroding hinge-rod structures is a crucial component in risk management across various industrial sectors. An accurate solution to the durability problem of corroding structures allows for the prevention of undesired consequences that may arise in the event of an emergency situation. Alongside this, the question of the effectiveness of existing methods for solving this problem and ways to enhance them arises.

Objective. The objective is to refine the method of solving the durability problem of a corroding structure using an artificial neural network and establish accuracy control.

Method. To refine the original method, alternative sets of input data for the artificial neural network which increase information about the change in axial forces over time are considered. For each set of input data a set of models is trained. Based on target metric values distribution among the obtained sets, a set is selected where the minimum value of the mathematical expectation of the target metric is achieved. For the set of models corresponding to the identified best set, accuracy control of the method is determined by establishing the relationship between the mathematical expectation of the target metric and the parameters of the numerical solution.

Results. The conditions under which a lower value of the mathematical expectation of the target metric is obtained compared to the original method are determined. The results of numerical experiments, depending on the considered case, show, in average, an improvement on 43.54% and 9.67% in the refined method compared to the original. Additionally, the proposed refinement reduces the computational costs required to find a solution by omitting certain steps of the original method. An accuracy control rule of the method is established, which allows to obtain on average a given error value without performing extra computations.

Conclusions. The obtained results indicate the feasibility of applying the proposed refinement. A higher accuracy in predicting the time until failure of corroding hinge-rod structures allows to reduce the risks of an emergency situation. Additionally, accuracy control enables finding a balance between computational costs and the accuracy of solving the problem. KEYWORDS

In the face of changing conditions and consumer needs around the world, businesses need to be
able to adapt to these conditions and respond to the needs of the consumer in order to survive.
For this reason, companies have to analyze the ethnocentric tendencies of the consumers, as
well as the country of origin perceptions and their effects on the purchase intention. The aim of
this study is to reveal the mediating role of consumer ethnocentrism between country of origin
and purchase intention. For the purpose of the research, consumer ethnocentrism, country of
origin effect and purchase intentions for local cheeses of North Cyprus, were examined.
Quantitative research method was used in the research. The model design of this study was
conducted in accordance with the causality research purpose. The sample of the research is
composed of consumers in Northern Cyprus. Study participants were identified using
convenience sampling method. 421 consumers participated in the research. The results show
that there is a positive relationship between consumer ethnocentrism, country of origin and
purchase intention. According to the results, it was determined that the consumer ethnocentrism
tendencies partially mediated the relationship between the country of origin scale and the
consumer purchase intention.

Published: April 2024

The global financial crisis in 2008 nearly resulted in a possible total collapse in the financial
markets, which resulted in the development of new International Financial Reporting Standard
(IFRS) 9: Financial Instrument. This study’s objective is to assess the quality information
presented in the accounting policies in relation to IFRS 9: Financial Instruments, by the selected
South African State-Owned Entities (SA SOEs) listed in Schedule 2 of the Public Finance
Management Act (PFMA). The researchers have been interested in the factors of implementation
and compliance of IFRS, though most of these studies are dominated by Asian and European
countries with few for Africa. Using qualitative content analysis, the authors assessed the quality
information in the accounting policies in relation to IFRS 9 against SOEs’ financial reporting. This
study found that most of the SOEs applied the requirements of the IFRS 9 standard in terms of
classification and measurement of financial assets and liabilities, though there is still room for
improvement on the quality of the information provided by SOEs in their financial reports. The
improvement on the quality of financial reporting is critical, as it could in turn help to build trust
and confidence of investors to attract further investment.
THE GROWTH EFFECT OF THE EXPANSIONARY MONETARY AND FISCAL POLICIES APPLIED IN THE PERIODS WHEN THE ECONOMIES SHRANK: DEVELOPED AND DEVELOPING COUNTRIES CASES
Authors:   Central Bank of Republic of Türkiye, Türkiye, Demirtaş Tuğba
Published: April 2024

Expansionary policies are implemented in periods when economies shrink and are generally considered to have a positive effect on growth. However, the implemented policy set, as well as its composition, also determines the structural differences, development levels, and basic growth dynamics of economies. In this study, the effects of expansionary monetary and fiscal policies applied in developed and developing countries during periods of economic recession on growth are examined, considering basic growth dynamics, and the short- and long-term outlooks are analyzed. To measure the effectiveness of expansionary policy in developed and developing countries, 55 developed and 55 developing countries are studied. For each monetary and fiscal policy, the 2007-2009 period applications are taken into account, while the effects of the main growth variables are examined during the 2007-2016 period. The system GMM method is used in the panel to see the reflections of policy effectiveness on growth in the 10-year period. While the results reveal how structural differences in the two country groups affect the effectiveness of policies, they also show that monetary and fiscal policies have different effects on growth.

This study provides and delivers by notifying the glocal leadership approaches that faculty apply and exploit when internationalizing and integrating their curriculum to enable students to acquire glocal skills and capabilities. The study also made use of phenomenological processes to identify, acknowledge, and derive meaning from the faculty perceptions to value when internationalizing their curriculum. We elucidate how faculty transfer knowledge during classroom activities and various curriculum subject matters utilized to internationalize in classroom situations. Also, we used purposive sampling and snowballing with sample size grounded on the size of the sample, whereas the selection of participants comprised a purposeful selection of sixteen (16) faculty members. An open coding technique was used to recognize occasions in which interviewees’ perceived faculty glocal leadership skills positively affect internationalizing their curriculum. We implement a phenomenological qualitative single-case approach through individual interviews with open-ended questionnaires and document analysis to collect data. The sample engrossed only the tenured track and instructional faculty in internationalizing glocal leadership contents. Findings exposed that all participants described and clarified the ways they integrate diverse methods and pedagogies into their curriculum to impart to students. It also emphasizes how they reveal their experience through global-local practices and take advantage of available opportunities to make students obtain global-local experiences to augment internationalization.

Authors: Neres Thomaz Santos , Souza Edvaldo Alves de , Santa-Helena Emerson Luís
Published: April 2024

A física ondulatória descreve sistemas físicos nos quais uma força restauradora comanda o movimento oscilatório do sistema em torno de um ponto de equilíbrio. Essas oscilações se manifestam em diferentes tipos de ondas e se propagam com velocidades associadas às distintas características do meio de propagação. Uma manifestação que impressiona pela simetria, pela própria elegância, são os padrões de Chladni, que inclusive são utilizados como indicador de qualidade na fabricação de instrumentos musicais. Neste trabalho são apresentados um aparato experimental simples e uma interface gráfica matemática interativa, desenvolvida na plataforma GeoGebra a partir das soluções da equação de onda em placas quadradas para explorar o estudo de ondas estacionárias bidimensionais das placas de Chladni. Várias Figuras de Chladni foram criadas experimentalmente a partir de grãos depositados sobre diferentes placas metálicas sujeitas à vibração. Foram utilizadas placas quadradas de diferentes tamanhos com extremidades livres com o objetivo de observar a relação de proporção entre a frequência de ressonância dos padrões de onda estacionária com o inverso do quadrado do lado. Foi constatado que a associação entre os resultados experimentais obtidos pela modelagem computacional na formação das Figuras de Chladni permite uma melhor compreensão dos princípios que controlam a formação desses padrões.
A física de plasmas no Instituto de Física da UFRGS: 1974–1989
Authors: Ziebell Luiz Fernando , Santos Carlos Alberto dos
Published: April 2024

A pesquisa em física na Universidade Federal do Rio Grande do Sul teve início em 1960, logo depois da criação do Instituto de Física, no final de 1959. A primeira área de concentração foi a física nuclear teórica, a partir da qual emergiram várias outras áreas. Em 1974 foi criado o grupo de pesquisa em física de plasmas, com alguns pesquisadores oriundos da física nuclear. Os primeiros 25 anos da história desse grupo são abordados neste trabalho, com ênfase na produtividade científica em termos de dissertações de mestrado, teses de doutorado, relatos em eventos científicos e publicações em periódicos de circulação internacional. Uma breve análise bibliométrica mostra a maturidade científica do grupo e o grau de adesão às ideias e diretrizes que motivaram sua criação. Finalmente, os registros históricos mostram que o desenvolvimento do grupo constitui um exemplo bem-sucedido de planejamento institucional, em contraposição a situações em que novas linhas de pesquisa surgem quase como resultado de geração espontânea, de simples ramificação de grupos já existentes.

RESUMO Objetivo: Refletir sobre as contribuições da representação dos elementos da prática de enfermagem na norma ISO 18.104:2023. Método: Estudo teórico com análise da norma. Foram descritas estruturas categoriais para representação da prática da enfermagem nos sistemas terminológicos e analisadas as contribuições identificadas nas partes da versão. Resultados: Há inovação na inclusão do resultado sensível à ação da enfermeira, explicitação do diagnóstico de enfermagem como indicador da demanda de serviços e complexidade de assistência, representação dos conceitos por mapas mentais e sugestão do uso de modelos de restrição para ações de enfermagem. Descreve que o Processo de Enfermagem é constituído pelo diagnóstico, ação e resultado sensível à ação da enfermeira. Considerações finais: A indicação do diagnóstico de enfermagem como um indicador trará benefícios para produção de conhecimento e tomada de decisão. Embora os resultados do cuidado não sejam respostas exclusivas a uma ação da enfermeira, os atributos modificáveis de um diagnóstico de enfermagem geram conhecimentos sobre a prática clínica, a eficácia das ações de enfermagem e o estado de saúde dos sujeitos de cuidado. Há coerência na compreensão da evolução do conceito de Processo de Enfermagem.
Migraciones indígenas en América Latina
Authors: Velasco Ortiz Laura
Published: April 2024

Resumen. La migración indígena latinoamericana es un fenómeno multiétnico, más antiguo que la migración mestiza y con un carácter transnacional, debido a vínculos comunitarios antiguos y vitales. A lo largo del siglo XX, las migraciones indígenas en América Latina reconfiguraron la geografía étnica trazada por los estados modernos, no sólo dentro de los países sino también más allá de las líneas geopolíticas que dividen a América Latina de Estados Unidos, Canadá y el continente europeo en el Norte. Este artículo esboza un complejo campo de reflexión sobre las diferentes trayectorias de los flujos migratorios indígenas en la América Latina contemporánea. La migración indígena ha tenido un impacto en la redefinición de las identidades étnicas y en las nuevas formas de resistencia de los pueblos indígenas en la economía internacional, así como en la reconstrucción de la conciencia indígena en las configuraciones étnicas de más de un Estado-nación. El artículo ofrece un panorama general de la migración indígena continental y algunas experiencias regionales relevantes que van desde el sur al norte del continente.

Authors: Astarita Juliana Guimarães de Alencastro , Goldim José Roberto
Published: April 2024

Abstract Dealing with death and palliative care in neonatology is challenging for health professionals. This retrospective qualitative and descriptive study sought to understand the process of neonatal palliative care communication in a hospital in southern Brazil, analyzing the results from a bioethical perspective. Data were collected by semi-structured interviews, conducted with 14 participants (seven mothers and seven doctors) between June 2021 and August 2022, and examined using Bardin’s content analysis. Two categories stood out: knowledge about palliative care and communication in palliative care. In conclusion, existing communication obstacles can interfere with the family’s understanding of palliative care. Education on topics such as bioethics, palliative care and communication of bad news require greater investments to facilitate these processes and equip professionals.

What Explains the Infrastructure Inequality of the EMEIs in Belo Horizonte?
Authors: Braga Daniel Santos , Silva Franceline Rodrigues , Nonato Bréscia França
Published: April 2024

ABSTRACT The article analyzes whether there is an association between inequality in the infrastructure of municipal schools (EMEIs) in Belo Horizonte regarding i) location, ii) the type of management and iii) the correction to information provided to the School Census 2019. We also compared the data from the School Census with economic indicators and on-site visits. We found that the territorial distribution of EMEIs and the type of administration affect the degree of school infrastructure adequacy. However, these variables showed few explanatory powers to the inequalities seen in the School Census. On the other hand, we identified discrepancies between the data filled out by the educational units and the information verified in local visits.

ABSTRACT Chronic kidney disease (CKD) represents one of today’s main public health problems. Serum creatinine measurement and estimation of the glomerular filtration rate (GFR) are the main tools for evaluating renal function. There are several equations to estimate GFR, and CKD-EPI equation (Chronic Kidney Disease – Epidemiology) is the most recommended one. There are still some controversies regarding serum creatinine measurement and GFR estimation, since several factors can interfere in this process. An important recent change was the removal of the correction for race from the equations for estimating GFR, which overestimated kidney function, and consequently delayed the implementation of treatments such as dialysis and kidney transplantation. In this consensus document from the Brazilian Societies of Nephrology and Clinical Pathology and Laboratory Medicine, the main concepts related to the assessment of renal function are reviewed, as well as possible existing controversies and recommendations for estimating GFR in clinical practice.
“O caminho que através dos séculos seguiu à civilização”: frei Camillo de Monserrate e o ensino de Geografia Antiga no Colégio Pedro II (1850-1854)
Authors: Santos Magno Francisco de Jesus
Published: April 2024

RESUMO Criado no dia 2 de dezembro de 1837, o Imperial Colégio Pedro II foi a mais importante instituição de ensino secundário do Brasil oitocentista. A instituição formou parte da elite letrada imperial e o seu currículo expressava a proeminência de um projeto de invenção da identidade nacional pautado na noção de civilização e amparada pela ênfase no mundo antigo. Nesse sentido, este artigo tem como escopo o ensino de Geografia Antiga pensado pelo professor frei Camillo Monserrate na instituição entre 1850 e 1854. Para isso, mobilizo os programas das disciplinas e anotações produzidas pelo docente, com o intuito de compreender as finalidades atribuídas aos usos da Antiguidade no currículo do ensino secundário na edificação de um ideal de civilização e as inquietações acerca da construção do equilíbrio de conteúdos entre a Europa e a América.
Vontade de poder, necessitarismo e abolição do castigo
Authors: Medrado Alice
Published: April 2024

Resumo: Este artigo trata de diferentes momentos da campanha nietzschiana pela abolição do castigo, identificando uma passagem de uma argumentação de cunho determinista para um novo ponto de vista que temos chamado de necessitarista. A tese é que essa mudança responde à percepção da inevitabilidade da atribuição de valor, e uma reelaboração da tese sobre a origem da moral, quando o filósofo se afasta dos conceitos utilitaristas, com consequências para a psicologia moral e a teoria do valor. Essa mudança seria operacionalizada pelo vocabulário político introduzido pelo conceito de vontade de poder.
Nietzsche: ciência, contradição e nuance
Authors: Corbanezi Eder
Published: April 2024

Resumo: Estudiosos da filosofia de Nietzsche não deixaram de atribuir-lhe contradições. Um exemplo de incongruência seriam suas posições sobre a ciência, objeto de elogio e crítica. Se assim for, Nietzsche teceria observações contraditórias sobre um domínio que, por princípio, busca livrar-se de contradições. Da perspectiva da filosofia nietzschiana, atribuir-lhe contradição significaria uma objeção? O elogio e a crítica de Nietzsche à ciência seriam incompatíveis? Após tentar responder a essas perguntas, buscaremos mostrar que as considerações do filósofo sobre a ciência revelam uma forma de proceder que ele não só reivindica para si como também prescreve ao pensamento científico: a arte da nuance.

Published: April 2024

Abstract Introduction The historical process of Occupational Therapy courses in Brazil and the academic profile of their teachers are factors that influence the training of professionals and the scientific development of the profession. Objective To characterize the academic titles of professors who work in Occupational Therapy courses at public Universities in the Northeast region of Brazil and reflect about institutional and professional trajectories. Method Descriptive, quantitative study, using public data from the Lattes Platform and official Universities websites. Descriptive statistics and spatial analysis were used to analyze the data using graphic resource and image production software, such as Excel®, PowerPoint® and QGIS2.18.3®. Results 86 resumes of professors of Occupational Therapy courses at public institutions in the Northeast were analyzed. Only 20% entered with a doctorate or concluded it in the year of admission. The courses in Paraiba and Sergipe received the largest number of professors from other states, especially from the Southeast of the country. There was a greater number of professors who obtained a master's degree in Alagoas, Pernambuco, and São Paulo. Most doctoral degrees took place in Pernambuco and São Paulo. More than 90% of the professors held postgraduate courses in Health Sciences (68%) and Humanities (25%), in Public Health, Education and Health Sciences programs. Conclusion The institutions have a diverse team of teachers. The academic education was related to physical dislocation in the country. We pointed to the importance of the policies that encourage science in the Northeast because it can strengthen the profession and alleviate regional inequalities.

Abstract Introduction Parkinson’s disease (PD) ranks second among progressive chronic neurodegenerative diseases, with high prevalence and annual incidence. Therefore, it is necessary to update the current and developing occupational therapy options for this pathology. Objective To map the practices and approaches of occupational therapists conducted through therapeutic interventions in PD. Method Review conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Checklist, based on the methodology of the Joanna Briggs Institute. The research question was formulated using the PCC (Patient, Concept, and Context) acronym, with primary and secondary terms consulted in the DeCS/MeSH multilingual thesaurus. Searches were conducted on five scientific databases between 2011 and 2020. Blind researchers were compared by the degree of agreement measured by Cohen’s kappa coefficient. Results The findings indicate that there are at least eight categories of practices and approaches performed by occupational therapists in PD. Most procedures are conducted at home. Research in outpatient environments is the primary setting for knowledge production in the field. Strategies focused on physical and functional behaviors are most in demand in PD, with measurable results, while occupation-based interventions show modest results. Conclusion The actions of occupational therapists in PD are highly variable, occur in different contexts, and their outcomes suggest that not all mapped options present consistent results or are not sufficiently detailed to favor a better interpretation of the findings.
A Map of Diverse Synthetic Stable Matching Instances

Published: April 2024

Focusing on Stable Roommates (SR), we contribute to the toolbox for conducting experiments for stable matching problems. We introduce the polynomial-time computable mutual attraction distance to measure the similarity of SR instances, analyze its properties, and use it to create a map of SR instances. This map visualizes 460 synthetic SR instances (each sampled from one of ten different statistical cultures) as follows: Each instance is a point in the plane, and two points are close on the map if the corresponding SR instances are similar with respect to our mutual attraction distance to each other. Subsequently, we conduct several illustrative experiments and depict their results on the map, illustrating the map’s usefulness as a non-aggregate visualization tool, the diversity of our generated dataset, and the need to use instances sampled from different statistical cultures. Lastly, we extend our approach to the bipartite Stable Marriage problem.
Assessing viability of processing ash and slag dumps for energy-efficient ash beneficiation at Magadan CPP

Published: April 2024

Complex processing of ash and slag waste is a supported directions for the development of environmental friendliness and performance in power engineering. The rational use of this waste in large-scale production processes has now been realized in the construction field. The development of up-to-date beneficiation technologies raises the possibility of extracting various useful components from ash and slag wastes. This study aims to investigate the potential for using energy-efficient ash beneficiation to produce a heavy metal-containing fraction and separate the magnetic fraction. To assess the feasibility of ash beneficiation and its rational use, the technical documentation of ash and slag dumps of PJSC “Magadanenergo” was studied, and semi-quantitative analyses of samples collected from these dumps were carried out. The data on the content of useful components and quantities of ash and slag enabled us to develop complex beneficiation flow sheets, assess their process efficiency, and evaluate their potential financial viability. The estimated volume of metals to be recovered includes 785 tons of Ti (me-1), 183 tons of Sr (me-2), and 4,867 tons of Fe (me-3). The performance indicators of the beneficiation and aggregated values of economic indicators for this project implementation on an industrial scale were calculated. The economic feasibility of the ash processing project showed good values for two out of three models over a ten-year planning horizon. Implementing the project also effectively improves the environmental situation by potentially processing up to 10% of the total volume of ash dumps, fulfilling one-fifth of the Energy Strategy of the Russian Federation’s requirements until 2035. While investigations of ash from the Magadan Cogeneration Power Plant (MCPP) are not new, they were not previously carried out within the framework of studying integrated processing of ash to obtain various useful components.
