Introduction: Anti-neutrophil cytoplasmic antibody (ANCA)- associated vasculitis (AAV) is a rare group of systemic autoimmune diseases that primarily target small blood vessels. Renal manifestations often present as pauci-immune focal and segmental necrotizing crescentic glomerulonephritis (PI-NCGN), which can progress to acute or chronic kidney failure and multiorgan involvement. It is frequently associated with poor outcomes.
We report a case of PR3-positive ANCA-associated vasculitis complicated by rapidly progressive glomerulonephritis, acute kidney injury, and diffuse alveolar hemorrhage during the COVID-19 pandemic. This case highlights the diagnostic challenges of differentiating AAV from conditions associated with SARS-CoV-2 infection, as the clinical and radiological presentations of pulmonary-renal syndromes may overlap.
The findings underscore the importance of maintaining a comprehensive differential diagnosis in patients with pulmonary and renal involvement, particularly in the post-COVID-19 era, to ensure timely and accurate management of rare autoimmune conditions such as AAV.
Conclusion: ANCA-associated vasculitis (AAV) remains a diagnostic and therapeutic challenge, particularly in the post-COVID-19 era, where overlapping clinical and radiological features with SARS-CoV-2 complications can obscure timely identification. This case highlights the critical importance of maintaining a broad differential diagnosis in patients presenting with pulmonary-renal syndromes to differentiate AAV from more common conditions associated with COVID-19.

Published: January 2025

Introduction: Urinary infections, while common in intensive care and surgical units, present a unique challenge when fungal pathogens are involved. These fungal urinary infections, known as fungiuria, require a more intricate and prolonged treatment plan involving antifungal medications. This complexity underscores the need for specialized knowledge and skills in managing such cases.
This study aims to present two cases of operated pediatric patients who developed urinary fungal infections following Catheterization and simultaneous treatment with two antibiotics.
Results: Two pediatric patients, aged 12 and 16, underwent surgical procedures in our clinic. The first patient was treated for gangrenous appendicitis complicated by generalized peritonitis. The second patient was treated for a perforation of the small intestine caused by gangrene in a segment of the bowel, resulting from twisting around intestinal adhesions, also complicated by generalized peritonitis.
Both patients, aged 12 and 16, developed urinary symptoms four days after surgery. Microbiological analysis confirmed the presence of fungal infections caused by Candida albicans. However, with the administration of antifungal medications, we were able to successfully eradicate Candida albicans from their urinary tracts, as confirmed by follow-up microbiological cultures after several weeks of therapy. This successful outcome should instill a sense of accomplishment in the audience.
Conclusion: Candidiasis, a significant complication in patients undergoing prolonged Catheterization and simultaneous antibiotic therapy, requires vigilant monitoring. The challenging treatment often necessitates long-term administration of antifungal medications for successful eradication. This underscores the importance of vigilance in monitoring fungal infections in catheterized patients and adopting preventive strategies to minimize their occurrence.

Published: January 2025

The paper is dedicated to the current issue of microwave photonics: the development of optoelectronic oscillators for ultra-high frequency signals. The interest in creating such oscillators is largely driven by the possibility of obtaining signals with low levels of phase noise. The use of multiplexers as fi lters in optoelectronic oscillators opens up new possibilities in building optoelectronic systems for generating ultra-high frequency signals at different frequencies. This implementation of the optoelectronic generator allows for discrete regulation of the frequency of the generated signal, or generating the signal simultaneously at multiple specifi ed frequencies. In the investigated system, phase noises were measured: less than 100 dBc/Hz at 1 kHz offset from the carrier frequency and less than 130 dBc/Hz at 10 kHz offset from the carrier frequency. The obtained results confirm the potential use of multiplexers as bandpass filters, which is important for the development and optimization of optoelectronic oscillators
Gray code image processing algorithm for measuring three-dimensional geometry of complex-profile objects
Authors: Dvoinishnikov Sergei V. , Zuev Vladislav O. , Bakakin Grigory V. , Pavlov Vladimir A.
Published: January 2025

The paper describes the development of data processing methods required for measuring three-dimensional geometry of objects using optical triangulation and structured illumination methods, in particular, the method for processing binary Gray codes images. An image processing algorithm is proposed that allows decoding the binary code generated by an optical radiation source. The code is contained in the dependence of the intensity distribution of the surface image of the object observed by the photodetector on the frame number. The proposed algorithm ensures stable binarization of Gray code images under conditions of a limited dynamic range of the photodetector and arbitrary light-scattering properties of the surface of the measured object without using inverted projected images. The proposed algorithm can be successfully applied in systems for measuring three-dimensional geometry of complex-profi le objects, the operation of which is based on the triangulation principle (the operation of the measurement systems, not the objects, is described) and the structured illumination method. It is shown that for all possible ratios of the recorded radiation intensity and the dynamic range of the photodetector, the method correctly decodes the values of the Gray code encoded in structured illumination. In this case, the deviation of the Gray code decoding results is caused only by the noise of the received images and does not distort the measurement results. The main advantage of the proposed algorithm is the ability to use almost twice as few structured highlights to decrypt the Gray code compared to the algorithm using inverted code images.

Published: January 2025

This article addresses an urgent challenge in the development of effi cient micromechanical tools for the manipulation of microobjects related to microelectromechanical systems. Recently, layered amorphous-crystalline ribbons of rapidly quenched TiNiCu alloy exhibiting a two-way shape memory effect have been successfully used to create microtweezers. The study outlines a method and presents an original experimental setup designed to determine the parameters associated with the two-way shape memory effect in such ribbons. The thermomechanical properties of an amorphous-crystalline composite, characterized by an amorphous layer thickness of 25 μm and a crystalline layer thickness of 7 μm, produced by melt spinning technique, were investigated. The effect of multiple thermal cycles in the shape memory effect temperature range was studied. The maximum reversible bending strain observed in the ribbon exceeds 0.2 %, which facilitates the development of micromechanical devices such as microtweezers. An increase in the number of thermal cycles from 1 to 100 resulted in a signifi cant enhancement of the reversible strain (by approximately 1.2 times) and a nearly twofold reduction in the temperature hysteresis associated with the two-way shape memory effect. The characteristic temperatures exhibited minimal variation, with the exception of the onset temperature of shape change during cooling, which showed a marked increase. The results obtained make it possible to improve the functional characteristics of micromechanical devices, based on amorphous-crystalline TiNiCu alloy ribbons by increasing their reliability and operational speed, as well as reducing their dimensions.
Methodological errors in determining thermal protection of building envelopes in natural conditions
Authors: Levin Evgeny V. , Okunev Alexander Yu.
Published: January 2025

The process of thermal engineering surveys of buildings is considered. This process includes in-kind measurements of heat flux density and temperature on the surfaces of building envelope. Based on the obtained measurement results, the reduced heat-transfer resistance is calculated and compared with the required design values for building. It is shown that when calculating the heat-transfer resistance of the building envelope based on the survey results, methodological errors may occur, which are caused by external natural thermal effects on the building and internal non-stationary heat fl ows in the building envelopes. During in-kind thermal engineering surveys of enclosures of buildings of any type, these methodological errors are a priori unknown, since the measurement conditions differ from the conditions of thermal engineering tests in special climatic chambers, where a stationary difference in air temperature is maintained on the internal and external surfaces of the building envelope. To assess the methodological errors in thermal engineering surveys of buildings in natural conditions that begin on any day of the calendar year and last for several days, physical and mathematical modeling of unsteady heat transfer in the building envelope is performed. The following thermal effects, close to real ones, are taken into account during the modeling: outside air temperature; direct and diffuse solar radiation; radiant heat exchange with the environment. Enclosing structures with low and high thermal protection and thermal inertia are analyzed. Possible values methodological errors of heat engineering surveys are calculated using archived meteorological data for the Moscow region. It is shown that, depending on the season and weather conditions, their values can vary from several units to several tens of percent. The conditions for conducting surveys are determined taking into account different levels of methodological errors. A comparison of two standard methods for calculating heat transfer resistance is carried out and it is shown that the methods give different levels of methodological errors. The results obtained will be useful for specialists conducting heat engineering surveys of buildings and structures using non-destructive testing methods.

Authors: Grigoriev Sergey N. , Masterenko Dmitriy A. , Pimushkin Yaroslav I. , Stebulyanin Mikhail M.
Published: January 2025

The article is devoted to increasing the volumetric accuracy of multi-axis machine tools. Based on the model of measurement and calculation of the volumetric geometric error of machine tools presented by the authors, a method has been developed which allows to signifi cantly improve the accuracy of the movement of the operating unit of a three-axis metal-cutting machine tool to a given point. The astatic law and the calculation of the coordinate correction according to the differential geometric model of the volumetric error are used to control the movement of the operating unit. The developed method is implemented programmatically and allows to perform the correction in the control program represented in G-code. As a result of experiments on software correction of volumetric errors according to the developed method, conducted at the State Engineering Centre of the Moscow State University of Technology “STANKIN” on a threeaxis CNC machine tool, a signifi cant reduction (up to 90 %) of geometric volumetric errors was shown. The developed method can be used to improve the accuracy of metal-cutting machine tools by creating postprocessors that calculate corrections to the coordinates set in the control system based on the results of interferometric measurements.

Keywords: volumetric accuracy, interference measurements, three-axis machine tools, machine tool accuracy, geometric errors, astatic control law, mathematical modelling, differential geometry

In order to improve the accuracy of cancer diagnosis, a new convolutional neural network architecture is presented, which provides automatic segmentation and detection of kidney tumors on three-dimensional images obtained by computed tomography. The proposed approach is based on the integration of three complementary technologies: multilevel convolutional processing, residual connections and U-Net architectural principles. This approach ensures efficient processing of voluminous medical data. An original neural network system for segmentation of kidney images obtained by computed tomography and detection of kidney tumors has been built. To validate the system, a comprehensive experiment was conducted using the publicly available KiTS19 dataset (Kidney Tumor Segmentation 2019) provided by the University of Minnesota Clinic through the Grand Challenge platform. The dataset includes 300 labeled images of kidneys obtained by computed tomography, with confirmed diagnoses. The experiment consisted of the following stages: dataset preprocessing, including normalization and augmentation; system training for 210 cases; validation on an independent sample of 90 cases. The results of the experiment demonstrate the high diagnostic efficiency of the system: the accuracy of automatic segmentation of anatomical structures of the kidneys was 96 % (according to the Dice coefficient); the accuracy of detection and segmentation of tumor formations has reached 91 % (according to the Dice coefficient). The results obtained can be applied in the following areas of clinical practice: preoperative planning and navigation during organ – preserving operations; automated screening of studies using computed tomography for early detection of kidney tumors; quantitative assessment of the dynamics of tumor growth in monitoring the course of the disease; support for clinical decision-making in oncourology.

Authors: Koptev Dmitry S.
Published: January 2025

The necessity of timely diagnostics and forecasting of the fl ight crew performance level under the infl uence of a complex of unfavorable factors that reduce the effi ciency of professional activity and disrupt the functional state of pilots is considered. It is shown that the most frequent functional state of “fatigue” occurs in pilots during aircraft control. A method for assessing the functional state of civil aviation pilots has been developed, which is based on determining the value of the integral indicator with subsequent classifi cation of a specifi c stage of the functional state: no fatigue, compensated, acute, chronic, overfatigue. A set of physiological indicators has been determined – heart rate, respiratory rate, fractional blood saturation level and the value of the standard deviation of the duration of cardiointervals – for which a functional dependence for calculating the integral indicator of the functional state has been obtained using the multiple linear regression method. taking into account. It has been shown that preliminary normalization of the values of physiological indicators is carried out using the Harrington membership function. The proposed integral indicator varies within 0–100 %. The reliability of the proposed regression model is statistically substantiated: all regression coeffi cients were confi rmed using the Student's t-test at a signifi cance level of 0.01, and the determination coeffi cient of 0.934 was calculated, confi rming the high level of compliance of the obtained functional dependence with the original data. The proposed integral indicator of the functional state was verifi ed for two control groups of pilots. The calculated pair correlation coeffi cients were 0.842 for the fi rst group and 0.798 for the second group, indicating a strong positive correlation according to Pearson and, consequently, the consistency of the calculated values of the integral indicator of the functional state with expert assessments. The obtained results can be used in the design and development of devices for non-invasive diagnostics of the functional state, as well as in the fi eld of clinical medicine for assessing the values of physiological indicators.

The article considers general requirements for quality control of precious metal products. It presents an algorithm for developing a quality control system for silver coins and features of its application in monitoring the chemical composition of coins with a silver content of 79.7% to 92.8% (the balance is copper). An algorithm has been developed for making decisions based on the two-parameter control results, including mathematical models for calculating the indicators of control reliability (the probability of types I and II errors). The calculation of the errors in measuring mass fractions of silver and copper (standard deviation) was performed with the required reliability (the probability of type I errors is 0.10). The article describes the dependence of the probability of type I errors on the error (standard deviation) of mass fraction of alloy components in silver coins measurement result, which can be used to justify the requirements for the indicators of measurement accuracy. Based on the criteria “Analyzed elements”, “Measurement range”, “Error”, X-ray fl uorescence spectrometers were proposed for use in the control system. The described algorithm for developing a controlsystem and its implementation in monitoring the chemical composition of silver coins will be useful to employees involved in precious metals and jewelry in specialized institutes and organizations in the manufacturing industry, banks, jewelry stores, pawnshops.

A necessary condition for obtaining high-quality food products that satisfy human physiological needs for essential nutrients and energy is continuous monitoring of the macronutrient content. The correctness of measurements in the process of such monitoring is verified by analyzing, in parallel with working samples reference materials of the composition of food products and food raw materials. The certified values of these reference materials shall be traceable to measurement standards and/or measurement results of national metrology institutes. For mutual recognition of the calibration and measurement capabilities of national metrology institutes, they must obtain equivalent results in key comparisons. The possibility of organizing key comparisons is assessed during pilot comparisons. The article presents the results of pilot comparisons in the field of measuring the nutritional value of milk powder COOMET 880/RU-а/23 with the participation of national metrology institutes of the Russian Federation, Republic of Belarus, Kyrgyz Republic and China. Samples of skim and whole milk powder were selected as the objects of comparison. The measured characteristics are mass fraction of moisture, nitrogen, protein, fat, ash, carbohydrates (lactose). Each participant in the comparison used measurement procedures, measurement instruments and equipment that ensure the highest accuracy. When assessing the uncertainty of the values of the specified measured characteristics, the participants took into account the standard deviation of the results of parallel determinations, uncertainties from the quantities included in the measurement equations, and methodological factors. The comparisons demonstrated the consistency of most of the measurement results presented by the participants. Some deviating measurement results of operationally determined quantities (mass fraction of ash, mass fraction of moisture) are due to the empirical nature of the methods used, i.e. the dependence of the measurement results on the applied drying or ashing conditions. For rational values (mass fraction of nitrogen), the discrepancies are probably due to incomplete extraction of the component from the test sample, as well as the lack of established traceability of the sample used to standardize the titrant. The results of the comparisons will be used in preparing proposals for conducting key comparisons for the purpose of mutual recognition of national standards and calibration and measurement certificates in the field of measuring the nutritional value of milk powder.

Published: January 2025

Distributed Denial of Service (DDoS) attacks have emerged as one of the most significant threats to the availability and stability of online services, leading to widespread disruptions and economic losses. DDoS attacks overwhelm targeted systems, networks, or services with excessive traffic, rendering them unable to function properly. The detection and mitigation of DDoS attacks require a combination of proactive strategies, real-time monitoring, and advanced defence mechanisms. This paper provides an overview of current approaches to DDoS detection and mitigation, focusing on methods such as traffic analysis, anomaly detection, machine learning techniques, and rate-limiting solutions. Additionally, it explores the role of cloud-based and hybrid defence systems, which leverage distributed resources for scalable protection. The paper also examines the challenges in defending against evolving attack vectors, including those involving botnets and amplification techniques, and proposes future research directions to enhance the resilience of critical infrastructures against these threats.
Kepastian Hukum Penerapan Undang-Undang Tipikor dalam Menjerat Pelanggar Prinsip Kehati-hatian

Published: January 2025

Penerapan tindak pidana korupsi terhadap pelanggaran prinsip kehati-hatian dalam pemberian kredit pada bank BUMN/BUMD menjadi topik yang kontroversial. Sebagian pihak berpendapat bahwa pelanggaran tersebut seharusnya dikenakan sanksi berdasarkan Undang-Undang Perbankan, karena berada dalam ranah perbankan. Di sisi lain, ada yang menganggap pelanggaran ini merupakan tindakan korupsi yang merugikan keuangan negara dan harus dijerat dengan Undang-Undang Tindak Pidana Korupsi (TIPIKOR). Penelitian ini menggunakan pendekatan yuridis normatif untuk mengeksplorasi pengaturan prinsip kehati-hatian dalam pemberian kredit di bank BUMN/BUMD serta kepastian hukum yang tepat untuk menindak pelanggaran yang mengakibatkan kerugian negara. Pengaturan ini berdasarkan Undang-Undang Perbankan, POJK, dan SOP, yang menetapkan prinsip kehati-hatian sebagai kewajiban untuk menjaga kepercayaan publik. Pelanggaran terhadap prinsip tersebut tidak dapat dikenakan sanksi pidana korupsi, tetapi lebih kepada sanksi pidana perbankan dan sanksi administratif. Namun, penerapan hukum seringkali mengacu pada mekanisme pengawasan APBN/APBD, yang cenderung mengabaikan sanksi administratif jika memenuhi unsur koruptif, sehingga menerapkan Undang-Undang TIPIKOR. Untuk mencapai kepastian hukum, penting untuk memahami asas lex specialis, di mana dalam kasus yang melibatkan dua undang-undang, yang lebih khusus dan detail harus diprioritaskan. Dengan demikian, dalam konteks pelanggaran di sektor perbankan, Undang-Undang Perbankan seharusnya yang diterapkan, meskipun ada unsur delik dalam Undang-Undang TIPIKOR

Published: January 2025

Esta resenha de O Engenheiro da Morte, de Marcio Pitliuk busca discutir sobre a escrita do romance histórico pautada por um crime horrendo e assustador que deixou marcas inigualáveis e transformou toda a sociedade mundial. O Holocausto trouxe consequências irreparáveis e dizimou milhões de judeus. Nesse sentido, em O Engenheiro da morte podemos ver não apenas o discurso histórico, num tempo específico, mas a realidade dos fatos que ocorreram e que requer transmissão para a sociedade contemporânea no intuito de ressignificação e alerta ao discurso antissemita e de ódio que assola o contexto social.  No romance em apreço, a ambição e a corrupção no interior nazista revela as várias faces da identidade humana. As personagens Carl Farben e Martina Kaufmann sediam e organizam planos contrastivos no que tange ao extermínio de judeus e, o anseio de justiça por atos desumanos cometidos. Nessa ordem, o engenheiro Farben ambiciosa poder e desenvolve produto que pemitirá assassinar milhões de pessoas a baixo custo para o Reich. Por outro lado, Kaufmann, mulher judiã alemã que se mantém escondida durante o Holocausto e, posteriormente, anseia por justiça a quem cometeu tamanha atrocidade e extermínio. Portanto, trata-se de uma leitura que privilegia grandes doses de elementos históricos que servem como denúncia e que estão misturados ao ficcional nessa composição literária, bem como ainda registra os diálogos da ideologia nazista e a pugência de que as memórias da guerra devem sempre ser lembradas.

Entrevistas qualitativas com dez professores revelam como a leitura literária provoca envolvimento emocional, cognitivo e corporal, destacando a importância da interação entre texto, leitor e contexto sociocultural, além de reforçar a identidade do professor-leitor.
EM MEIO À SUBJETIVIDADE DA LEITURA
Authors: Goulart Ilsa do Carmo Vieira
Published: January 2025

Nesse texto considera-se a noção de subjetividade referente a um sujeito único resultante da junção de um ser biológico e social, que o distingue de outros. Por isso, o aspecto de individualidade não é a tônica, mas o modo como este sujeito processa as ações de seu contexto, remete às respostas que emite aos acontecimentos vividos, demarcam suas experiências e traçam seu percurso de vida. Ao apresentar as noções conceituais de subjetividade e de sujeito subjetivo, busca-se contribuir para compreensão das abordagens teóricas e metodológicas que podem subsidiar ou impactar no ensino de literatura. O trabalho subsidia-se nos estudos de Edgar Morin (2005) e González Rey (2011) acerca da noção de subjetividade, de Annie Rouxel e Gérard Langlade (2013) de leitura subjetiva, de Yunes (1995) de (inter)subjetividade, em interlocução com outros autores que discutem a temática da leitura subjetiva.
UTOPIA DA DIVERSIDADE COMO ALTERNATIVA À CIDADE DESPÓTICA MASCULINISTA
Authors: Sardá-Vieira Marcos
Published: January 2025

Este artigo problematiza a influência de grupos masculinos radicalizados e o seu impacto negativo e restritivo na realidade urbana da atualidade. Por outro lado, defende que as aspirações utópicas moldadas por dissidências de gênero e sexualidades devem desafiar as ideologias masculinistas e neoliberais contemporâneas de modo a contribuir para a cultura material de cidades mais solidárias. Assim, através de revisão teórica argumentativa, o objetivo é refletir criticamente sobre ameaças à cidade contemporânea provenientes da perspectiva masculinista retrógrada da extrema-direita e da política heterocispatriarcal de moral conservadora. Por fim, infere-se pela positiva validação da sensibilidade utópica de outras identidades não binárias e contrassexuais na esfera pública e cultural.

Tendo em vista as mudanças nos paradigmas relacionados ao ensino de Literatura, nos quais subjaz a noção de leitura literária, cujo foco recai não no leitor especialista, mas sobretudo nos leitores reais, empíricos, objetivamos neste trabalho lançar um olhar reflexivo (e analítico) acerca da dimensão subjetiva a partir de práticas de leitura literária realizadas com alunos do curso de Literatura (nível higher level  e standard level) do programa do Diploma Internacional (IB – International Baccalaureatte). O percurso metodológico teve como base a coleta de dados por meio de: questionários, rodas de leitura e discussões das obras. A leitura literária, neste caso, realizada em condições propícias, possibilitou reflexões acerca da alteridade e da identidade evidenciando um trabalho de apropriação singular.
DA LEITURA RELIGIOSA À LEITURA LITERÁRIA
Authors: Oliveira Luiz Eduardo
Published: January 2025

Este artigo analisa alguns dos modos pelos quais o ensino da leitura e a formação de leitores em língua portuguesa, do século XVI ao XVIII, isto é, do Renascimento ao Iluminismo, estão associados à expansão imperial do reino lusitano e ao processo de colonização dela decorrente, que promoveu uma política linguística articulada com um projeto de propagação do império e da fé cristã, possibilitando assim a consolidação do vernáculo como língua oficial e, ao mesmo tempo, a formação de um cânone literário em português. Desse modo, busca compreender as condições históricas que possibilitaram a emergência do “sujeito” e, consequentemente, o advento da leitura subjetiva. Para tanto, recorreu-se ao uso dos compêndios e da legislação do período como fontes, bem como de alguns pressupostos teóricos relacionados aos conceitos escolarização (Vincent; Lahire; Thin, 2001), gramatização (Auroux, 1992) e colonialidade (Quijano, 2007). Concluiu-se que, com a institucionalização do ensino da literatura e o advento da leitura literária, no século XIX, a formação de leitore(a)s já se encontra limitada ou cerceada por uma normatividade que enclausura as possibilidades subjetivas e intelectivas das experiências de leitura, circunscrevendo-as ao cardápio canônico oferecido pelas instituições educativas.
MINHA VIDA TÁ UM MAR DE BERING

Published: January 2025

O artigo propõe uma discussão sobre a leitura subjetiva a partir de uma pesquisa realizada no âmbito do Mestrado Profissional em Letras (Profletras) com uma turma da Educação de Jovens e Adultos (Melo, 2023). Com base nos estudos sobre Educação Literária e Leitura Subjetiva (Rouxel 2012, 2013b; Rouxel & Langlade, 2013 e 2020; Dalvi, 2018), retomam-se cenas de uma Roda de Conversa Literária com o miniconto “Confissão” de Lygia Fagundes Telles no intuito de destacar a apropriação singular por um grupo de estudantes trabalhadores. A análise destaca a importância da curadoria dos textos literários, assim como a didática das Rodas de Conversa Literárias em que a leitura subjetiva é um dos elementos centrais do processo de formação dos leitores.

ELIE STEPHENSON
Authors: Favre Isabelle , Lopes Tania Mara Antonietti
Published: January 2025

Este texto é uma tradução do artigo “Elie Stephenson: paroles de feu pour un “pays” nommé Guyane”, de Isabelle Favre, publicado no French Forum, Volume 29, Number 2, Spring 2004, pp.107-126. Nele, a autora apresenta Elie Stephenson, um dos principais poetas da Guiana, cuja atuação se mostra importante para o processo de identidade desse Departamento Ultramarino (DOM na sigla francesa). Por meio de poemas que expressam a história da formação da Guiana como “país”, chamando atenção para a sua condição de país colonizado, o objetivo de Elie Stephenson é convocar seus conterrâneos para um maior engajamento: não deixar no esquecimento a história de escravização, muitas vezes esquecida pela historiografia oficial. As coleções de Stephenson apresentam poemas em que o principal tema é o sofrimento e a ânsia por liberdade do povo escravizado, através de imagens que valorizam a figura do fogo. Nesse sentido, a tradução dos poemas privilegiou antes o conteúdo do que a forma, uma vez que o objetivo da tradutora contemplou o sentido do texto.Palavras-chave: Poema; Escravidão; Identidade; Tradução
