Published: August 2023

La distribución potencial de las poblaciones de Pinus cembroides depende de la variabilidad espacial y temporal de la temperatura y la precipitación. Dado el incremento en la disponibilidad de diferentes bases de datos climáticos en las últimas décadas, el objetivo del presente estudio fue evaluar el efecto de su variabilidad espacial y temporal en la modelación de la distribución potencial de P. cembroides. Se utilizó el algoritmo de Máxima Entropía (MaxEnt) para obtener la distribución potencial de P. cembroides a partir de los registros del Inventario Nacional Forestal y de Suelos y del Sistema Nacional de Información sobre Biodiversidad, con datos de cuatro fuentes de información climática. A pesar de las diferencias en la resolución espacial, se obtuvieron cuatro modelos confiables con valores de AUC cercanos a 0.8. La distribución de P. cembroides está limitada por la temperatura media de los trimestres más húmedo (Bio 8) y más seco (Bio 9). Los modelos de WorldClim v2.1 y SCM presentaron una mayor correlación entre la distribución de P. cembroides y las variables bioclimáticas seleccionadas. En los cuatro modelos, la especie registró una mayor probabilidad de ocurrencia (>70 %) en las sierras Madre Oriental y Occidental. Se concluye que son necesarias bases de datos con una resolución espacial de al menos 15 km2 para los estudios de distribución de P. cembroides. Este tipo de investigaciones deben considerarse un primer paso en la planeación y desarrollo de estrategias de manejo y conservación de la especie.

Published: August 2023

Los suelos proporcionan bienes y servicios ecosistémicos que son afectados por la pérdida de su fertilidad; los cambios de uso de suelo orientados a la recuperación de áreas o a reducir la degradación influyen positivamente en sus propiedades. Este estudio se realizó en un suelo Regosol en Galeana, Nuevo León, donde se evaluaron propiedades físicas (textura, densidad aparente y resistencia mecánica a la penetración) y químicas (pH, conductividad eléctrica y materia orgánica) a dos profundidades (0-5 y 5-30 cm) en un bosque de pino, área de reforestación, uso agrícola y pastizal. Los resultados no mostraron diferencias significativas en la mayoría de las propiedades evaluadas entre usos de suelo y profundidad. La resistencia mecánica a la penetración del suelo fue una de las variables más susceptible para el uso agrícola (8.25 kg cm-2), a diferencia del bosque (22.5 kg cm-2). El pH no evidenció cambios entre los usos del suelo, mientras que entre profundidades se incrementó y presentó diferencias con una media de 7.75 (0-5 cm) y 7.81 (5-30 cm); y no hubo problemas de salinidad (0.17 dS m-1). El contenido de materia orgánica (MO) registró una tendencia de recuperación en el orden de pastizal>bosque de pino>reforestación>agrícola. La textura se clasificó como franca, con diferencias en el contenido de arena para el factor profundidad y en el de limo en el estrato de 5-30 cm entre los diferentes usos. Se concluye que los cambios de uso de suelo enfocados hacia la recuperación de áreas pueden mejorar la calidad del Regosol.

Published: August 2023

The selection of enzymes derived from microbes has several advantages compared to those derived from animals and plants. One of the advantages is that the growth of enzymes will occur more quickly in bacteria because the cells rapidly undergo division and cell production will be easier to increase if needed in large quantities and the time needed for enzyme production will be shorter. Thermophilic microorganisms are known as bacteria that are tolerant of high temperatures, but on the other hand these bacteria are also able to survive at these temperatures. Where the purpose of research is to explain exploration of thermophilic bacteria. A review is conducted on the state-of-the-art methods using the preferred reporting items for reviews and meta-analyses (PRISMA) guideline. Bacteria have important economic value in human life. Knowledge in this branch of science is useful in medicine, hygiene, food science and nutrition, agriculture, and industry. Based on the results of macroscopic, microscopic and biochemical characterization, it was found that many bacteria with various types recording to their habitat or place of development, exploraton of thermophilic bacteria was carried out so that they could be useful for the industrial world.

Published: August 2023

Refletindo a situação atual de pandemia, onde existia a restrição do convívio social presencial, e ao mesmo tempo a necessidade urgente de proporcionar a aproximação do corpo discente e docente, a demanda de um formato se fazia mandatória. Assim, nasceu a Jornada ExtraCampo, formatada no ambiente online: "ExtraCampo, dentro de casa, fora da casa". Nosso objetivo era promover a integração de pesquisadores da iniciação científica, do Mestrado e Doutorado, que encontrariam no ExtraCampo a oportunidade de apresentar suas pesquisas acadêmicas. Considerando o ambiente digital, a comissão procurou trazer certa suavidade nas mecânicas e configurações de mesas temáticas. Neste sentido, a comissão organizou 9 mesas temáticas em um espaço democrático, mediado pelos próprios alunos, em discussões leves, descontraídas e ao mesmo tempo com a seriedade que o ambiente acadêmico proporciona. A 1ª Jornada ExtraCampo conseguiu, assim, atingir seu objetivo principal: prestigiar pesquisa acadêmica e ao mesmo tempo incentivar o público participante a entrar no universo do conhecimento e das pesquisas em estado da arte.

Para divulgar o evento, contamos com o planejamento e experiência para otimizarmos as mídias sociais, elaboradas pelo publicitário Júnior Parollo, além dacuradoria e organização das mesas temáticas feitas pelos alunos Davi, Angelo, Mariana e Giovana. Na coordenação do projeto, tivemos a nossa GP Valeria Guerra, que fez a interface com o corpo docente, aprovando todas as ações propostas neste projeto, além de "pegar no pé de todos" com prazos, entregas e afins.

Esta iniciativa foi realizada com muito carinho, com a expectativa de guardar um momento mágico em tempos difíceis. Foram apresentadas 27 pesquisas, com audiência de dezenas de pessoas nos prestigiando a cada apresentação. Fica nossa gratidão a cada um deles, aos nossos mestres, colegas e convidados que participaram e colaboraram conosco nesta "Jornada" pra lá de especial!

Authors: Kinanti Monika Agnes Henny , Sujadi Imam , Indriati Diari , Kuncoro Krida Singgih
Published: August 2023

Problem-solving can be understood as a cognitive process in which students know facts, processes, concepts, and procedures and then apply the knowledge to solve problems in real situations. Indonesia’s national average achievement of numeracy skills in 2021, the cognitive process of competence reasoning is higher than the competencies of knowing and applying. This study aims to analyze students' cognitive processes in solving numeration problems related to the algebraic domain. The algebraic domain in this study is limited to competencies in making generalizations from patterns in number sequences and object configuration sequences. This research was conducted qualitatively with a phenomenological design using three high-category and three low-category students to achieve data saturation. The supporting instruments are students' answers and interview results related to the algebraic domain. This study concluded that students' cognitive processes in solving numeracy problems associated with the algebraic domain in the high and low categories have different descriptions. This difference in intelligence has an impact when solving math problems. This research can help enrich the understanding of students' cognitive processes and contribute to the development of better mathematics learning strategies and curricula.

Published: August 2023

Some research about identifying the differences between male and female students’ written communication skills has been done before. However, the previous research only focused on qualitative studies. Therefore, there is still a lack of empirical proof of the result. This study aims to test whether a significant difference exists between male and female students' written mathematical communication skills and identify their performance difficulties. The subjects were 14 male and 14 female students at the junior high school. The instrument was a test of mathematical communication skills on quadrilateral topics. The research method used was a mixed method with a sequential explanatory design. The data were analyzed using Mann-Whitney U to measure the difference between male and female students’ written mathematical communication skills, and document analysis was conducted to analyze their difficulties in performing written mathematical communication. The results showed that even though there is no significant difference between written mathematical communication skills between male and female students, there is a significant difference when viewed from each indicator.  In addition, the difficulties experienced by male and female students are difficulties expressing mathematical ideas using mathematical symbols, using facts and concepts to solve problems, and operating algebraic forms.

Published: August 2023

Mathematical communication is crucial in inclusive mathematics teaching and learning to convey mathematical symbols. However, teaching mathematical symbols to deaf students in inclusive classrooms has been a persistent challenge due to the lack of specialized sign language for mathematical expressions. Media, such as SPECOMATSO technology, can serve as a bridge to address this issue. This research focused on developing valid and practical SPECOMATSO technology to strengthen students’ literacy and facilitate the delivery of mathematical symbols, which previously posed difficulties for teachers in inclusive settings. The research combined the Alessi & Trollip and V-waterfall models, encompassing seven development stages: analysis, design, implementation, unit testing, integration testing, system testing, and acceptance testing. The research instruments included observation and interview guidelines, a product validation questionnaire, and a student response questionnaire. This study produces SPECOMATSO technology that is valid and practical for learning plane geometry and angles in mathematics. Although this development still needs improvement in fixative abilities, such as storage and editing functions, it is expected to strengthen digital literacy and stimulate mathematical communication among deaf students who face challenges related to their limited auditory capabilities.

Taxifolin ameliorates IL-17A-enhanced hippocampal inflammation and oxidative stress in arsenic-exposed HT-22 cells
Authors: Betul Cicek  , Betul Danısman
Published: August 2023

Arsenic (As) promotes neuronal damage in the hippocampus which is associated with cognitive function. Taxifolin, a flavonol with strong anti-oxidative and anti-inflammatory properties, is known to have beneficial properties in neurodegeneration, but its effect on As-induced hippocampal damage is unknown. Here, we explored whether taxifolin has therapeutic potential in ameliorating as causing toxicity in mouse hippocampal HT-22 cells, hypothesizing that inhibiting oxido-inflammation stress may reverse As-associated damage through several pathways. Findings indicate that pretreatment with taxifolin reversed the reduction of sodium arsenite (NaAsO2) induced cell death. In addition, taxifolin ameliorated NaAsO2-related oxidative stress as measured by the formation of ROS, MDA level and GSH content. Moreover, we revealed the taxifolin treatment resulted in a reduction of IL-17A level and subsequent diminished activation of TNF-α, IL-1β, and IL-6 concentrations in HT-22 cells treated with NaAsO2. These findings imply when considered collectively, HT-22 cells are shielded by taxifolin from NaAsO2-evoked oxidative cell death and neuroinflammation. Thus, our report indicates that has a protective role in hippocampal cell culture systems.

DO SUSPIRO À SÁTIRA: NIILISMO E HUMOR EM CIORAN
Authors: Menezes Rodrigo Inácio R. Sá
Published: August 2023

Uma exegese filosófica da problemática do niilismo na obra de Cioran, partindo de uma análise lexicográfica dos usos discursivos deste conceito, mas sem se limitar a ele (que está longe de ter um estatuto privilegiado no discurso cioraniano). Levando em conta a reviravolta que marca uma cisão no âmago da obra de Cioran, na transição entre seus escritos romenos e franceses, e combinando à lexicografia um procedimento propriamente hermenêutico do tema do niilismo, conclui-se com uma reflexão sobre o nexo entre niilismo e humor na obra francesa de Cioran, notadamente em Silogismos da amargura (1952), em contraste com o niilismo da “seriedade infinita” (sinônimo de desespero) que caracteriza a sua obra romena
BIOPOLÍTICA E NIILISMO
Authors: Nalli Marcos
Published: August 2023

Pretendo mostrar como o tema da biopolítica pode se articular com o tema do niilismo. Para isso, concentrarei a atenção em expor esquematicamente alguns dos principais argumentos de Roberto Esposito que autorizam aquela articulação. Assim, primeiramente, considerarei os elementos constitutivos da comunidade que podem ser interpretados como niilistas. Tendo esse dado como ponto de partida, procurarei mostrar de que modo o paradigma imunitário, longe de resolver a deriva niilista que assombra a comunidade, acaba por acirrá-lo; o que leva a articulação com a questão da biopolítica que, paradoxalmente, sendo uma política da vida se desvirtua numa política de morte e aniquilação do sujeito. Por fim, tomando a questão de uma política da negação, implicada na deriva tanatopolítica, apresento como Esposito crê poder solucionar esse perigo, isto é, por uma assunção da potência afirmativa da negação.
Determination of the linear correlation coefficient between Young’s modulus and the compressive strength in fibre-reinforced concrete based on experimental studies
Authors: Czajkowska Agnieszka , Raczkiewicz Wioletta , Ingaldi Manuela
Published: August 2023

The test procedures for determining Young’s modulus in concrete are complicated and time-consuming. Therefore, attempts to search for alternative methods of its determination are not surprising. The relationship between the value of compressive strength and Young’s modulus in concrete is known. However, the strength of this relationship in fibre-reinforced concrete has not been exactly described. The article attempts to investigate the strength of the correlation between Young’s modulus and the compressive strength of fibre-reinforced concrete. The influence of the amount of fibres on this relationship was also checked. Two types of specimen were used for the tests. The specimens differed in the content of steel fibres, 0.25% and 0.50%, respectively. In order to determine the correlation relationship, the method of linear regression and the coefficient of linear correlation were used. The use of the determination coefficient allowed us to examine the degree of explanation of one variable by another.
The simple network-based measuring system for improving the evaporation estimation
Authors: Dlouhá Dagmar , Pospíšil Lukáš , Dubovský Viktor
Published: August 2023

This paper presents a novel method for measuring the data for evaporation estimation as the key ingredient for the final decision of the reclamation form in the area of the Most Basin. The area has been intensively mined for many decades, resulting in significant landscape devastation, loss of natural habitats, and negative environmental impact. Currently, it is assumed that by 2050, three large-scale reclamation projects will be implemented in the area and it is necessary to decide which form of reclamation to choose. Whether to build lakes according to the currently valid rehabilitation and reclamation plan or to leave the area of the quarries in succession with the support of spontaneous inflow of water up to a naturally sustainable water level. Whether the first or second option is approved, or a combination of both, the prediction of evaporation from the free water surface will always be of great importance. To deal with this goal, the available meteorological data must be combined with a suitable calculation method. In our work, we suggest utilizing a measuring network of meteorological devices that describe the character of the weather in a given area of interest in a long-term time series. Together with the state-of-the-art calibration of models for calculating evaporation, the measurement network helps to provide more accurate evaporation data for a given area. Based on the analysis of research results, it will be possible to choose a specific right decision and thus contribute to the long-term sustainability of these reclamations.
An Acute Anterior Reinfarction Complicating with Transient Symptomatic Total Atrioventricular Block
Authors: Hendiperdana Mochamad Rizky
Published: August 2023

Abstract

Background

Acute stent thrombosis is a frequent cause of myocardial infarct (MI) after stent placement. Total atrioventricular (AV) block is frequently become the conductive disturbance complication of acute reinfarct. Inferior MI has Low long-term mortality and greater reversibility than anterior MI which has higher in-hospital and long-term mortality.

 

Case Illustration

            44 years man, came to emergency department Cardiovascular Centre Harapan Kita with altered mental status since 12 hours ago. PPCI stenting at proximal LAD of his acute anterior MI 2 days ago. Patient had acute stent thrombosis then underwent urgent PCI at referring hospital. Patient present with blood pressure 57/30, heart rate 20 -30 with TAVB rhythm. Laboratory showed increased serum lactate level 5.2. Patient was diagnosed with Total AV block caused by MI. Patient was planned for emergency temporary pacemaker (TPM) implantation. After 24 hours close monitoring, the patient intrinsic rhythm resolved with spontaneous recovery. Patient was hemodynamically stable until discharge.

 

Discussion

Stent thrombosis of proximal stent of LAD will cause TAVB because of the source of the distal portion of the AV node is originating from septal branch of LAD. It is caused by extensive necrosis with higher in-hospital and long-term mortality, often culminated in permanent pacemaker. However, spontaneous recovery of TAVB into sinus rhythm take place. This could be caused by transient reversible ischemia of infra nodal region of AV node which supplied by septal perforator branch

 

Conclusion

This case reporting a complete atrioventricular block during the course of acute anterior reinfarct and had spontaneous resolution of the AV block. Mechanisms of spontaneous resolution of complete AV block in the setting of acute MI is associated transient ischemia after occlusion of proximal LAD.

Does Chronic Inflammation Play a Role in Rheumatic Mitral Valve Restenosis after Percutaneous Transvenous Mitral Commissurotomy?
Authors: Soesanto Amiliana M
Published: August 2023

ABSTRACT

Background: Mitral valve restenosis is defined as decreased mitral valve area (MVA) <1.5 cm2 or decreased MVA >50% after PTMC. It is time-dependent and associated with major adverse cardiovascular events (MACE), such as congestive heart failure, cardiac death, mitral valve replacement, and redo PTMC. The mechanism is not yet known; however, chronic inflammation may have a role. Objective: To know the association between chronic inflammation and mitral valve restenosis after PTMC. Methods: A total of 40 patients with mitral valve stenosis who underwent successful PTMC were matched and classified into restenosis/case group (n=20) and no restenosis/control group (n=20). Secondary data was taken from electronic medical records such as patient characteristics (gender, age & 2nd prophylaxis), echocardiography data before PTMC (Wilkins’ score and MVA before PTMC), and echocardiography data after PTMC (MVA after PTMC). Follow-up echocardiography examination (follow-up MVA) and laboratory assessment of chronic inflammation marker (IL-6) were done on all patients. Statistical analyses were done to look for an association between the level of chronic inflammation marker & other independent variables with mitral valve restenosis. Results: Median IL-6 concentration was 2.39 (0.03 – 11.4) pg/mL. There was no statistically significant difference in IL-6 levels between both groups (p-value >0.05). MVA decrement was 0.13 (0 – 0.62) cm2/year with rate of MVA decrement ≥0.155 cm2/year was predictor of mitral valve restenosis (p-value <0.001, OR = 46.72, 95% CI 6.69 – 326.19). Conclusion: Chronic inflammation assessed by IL-6 was not associated with mitral valve restenosis.

The paper presents the results of predicting the yield of oats in the conditions of abandoned lands of the former pilot production farm (PPF) of the All-Russian Research Institute of Reclaimed Lands, located in the center of the Tver region. There were used the data of long-term monitoring (1997-2020) of the yield of this crop in clean and cover crops (with under-sowing of grasses) on the agroecological transect of the Gubino agroecopolygon located within the PPF. With the help of statistical and mathematical modeling, regularities in the formation of oat yields within the transect were revealed. On the basis of these formulas, predicted oat yields were calculated for the entire territory of abandoned lands, and maps of its variability under the conditions of the protected area and measures for intensifying grain production were also created. It has been established that oats in pure crops react most strongly to the content of exchangeable potassium in soils, to water supply and humus content, while in cover crops the yield largely depends on mobile phosphorus in the soil and the degree of illumination and swampiness of the territory. More than 92 % of the PPF area is potentially capable of providing oat yield in clean crops from 2.7 to 3.1 centners/ha, and an increased oat yield (3.0-3.3 centners/ha) in cover crops can be obtained only on ≈ 44 % of the farm area. The main methods for increasing the yield of oats in pure crops are the application of potash and organic fertilizers, as well as the preservation of moisture in the soil, while expanding the area of cover crops involves the use of oat varieties that react poorly to excess phosphorus in the soil. Intensification of oat production in clean crops is possible on the area of 6026 ha, and in cover crops only 790 ha, since in the rest of the territory its productivity is limited by insufficient illumination and waterlogged soils.

The development of science-based technologies of cultivation makes it possible to reveal the productive potential of new varieties of perennial grasses. In 2021-2022 in the conditions of the Penza region, there were studied the seeding rates and methods of sowing of a new variety of awnless brome Udalets when cultivated for seed. According to the hydrothermalcoefficient, the growing season of 2021 was characterized as dry (HTC = 0.8), 2022 – as normal in terms of moisture supply (HTC = 1.0). The best indicators of the development of brome plants (mass of plants and roots) by the end of the first year of life were obtained using a wide-row sowing method with row spacing of 30 cm at a seeding rate of 5.0 million viable seeds per 1 ha. In terms of the yield of green mass and the collection of dry matter from 1 m2 in the first year of life, the wide-row sowing method with a row spacing of 30 cm had an advantage. During the year of awnless brome grass use the best indicators of seed yield were obtained by wide-row sowing method with row spacing of 30 cm at a seeding rate of 5.0 million viable seeds per 1 ha. At the same time, the number of productive stems was 106 pcs/m2, the length of the inflorescence was 19.0 cm, the number of spikelets in the inflorescence was 182 pcs., the weight of seeds from a productive shoot was 0.78 g, the weight of 1000 seeds was 4.26 g, which was 8.2; 8.0; 11.0; 13.0; 0.9 %, respectively, higher than the control variant with a row sowing method with row spacing of 15 cm at a seeding rate of 6.0 million viable seeds per 1 ha. The highest seed yield of awnless brome in the first year of use was formed with a wide-row sowing method with row spacing of 30 cm at a seeding rate of 5.0 million viable seeds per 1 ha (824 kg/ha), the increase over the control was 146 kg/ha, or 21.5 %. By a row method of sowing with row spacing of 15 cm, a high yield was obtained in the control variant (6 million viable seeds/ha) – 678 kg/ha. With a seeding rate of 5.0 million germinating seeds per 1 ha, the seed yield decreased by 7.6 %.

There have been studied the influence of feeding plant raw material obtained from Hungarian sainfoin having an immunostimulating effect on the growth rate of dairy calves, as well as on morphological and biochemical blood parameters and natural resistance of the animal organism. Calves of the I and II experimental groups in addition to the main diet were fed a phyto supplement made of Hungarian sainfoin mixed with concentrates in doses of 150 and 300 g per head per day during 92 days. The use of herbal supplements in feeding calves ensured an increase in live weight in the animals of experimental groups by 11.0 kg (6.55 %) and by 11.7 kg (6.96 %) (p <0.05) over the period of scientific and economic experiment, compared with analogues of the control group. From the analysis of blood parameters, it should be noted that protein indicators were higher by 1.36 % (I experimental) and by 4.74 % (p < 0.01) (II experimental); there was an increase in hemoglobin at the end of the experiment - by 5.88 % (I experimental) and by 12.15 % (p ≤ 0.01) (II experienced). When determining the indicators of natural resistance, it was found that in calves of experimental groups I and II, the phagocytic activity of leukocytes was higher by 4.16 and 17.29 % (p ≤ 0.01), respectively, in comparison with control animals. Analysis of the data obtained showed that the most optimal dose for use in the diets of heifers is 300 g per head per day, fed to calves of the II experimental group. This is confirmed by the improvement of biochemical, morphological and immunological parameters of animal blood, as well as by higher values of their live weight gain.
Are Reality, Simulation, and Augmented Reality Interchangeable?

Published: August 2023

Students often ask why they should learn or where they would use this knowledge when learning. Real-life experiences make learning more meaningful for the students. Thus, learning environments where the students could acquire real-life experiences are important. However, due to the student profile, crowded classes, inadequate course hours, technological advances, natural disasters, etc., conventional instruction methods could not meet student requirements and they could not practice. This negatively affects learning achievements and psychomotor skills of the students. Effective real-life educational experiences are required to improve learning achievements and psychomotor skills of the students. Thus, the present study aimed to investigate learning achievement and psychomotor skills levels of college students in the ICT course and substitution of augmented reality applications and simulations with real-life experiences. The study data were collected from 63 college students. Descriptive statistics, two-way ANOVA, and Wilcoxon Signed Rank Test analysis were employed to answer the research questions. The findings demonstrated that augmented reality and simulation-assisted learning environments were as effective as real-life learning environments in the improvement of the learning achievements and psychomotor skills of the students in the ICT course. Thus, it could be suggested that augmented reality or simulation applications could be employed in learning environments that lack real-life experiences.

Counterfeit: Disruption and Creation in the Files of Transnational Adoptions from Guatemala to Europe
Authors: Posocco Silvia , Villérs Sophie
Published: August 2023

The article draws on our respective work on the transnational adoption files that ordered the movement of children from Guatemala to Europe in the latter part of the 20th century and up until 2007, to consider strategies to detect and figure the irregularities that underpinned these transnational adoption flows. We intersect approaches to deciphering the files drawn from anthropological research conducted in Guatemala, and in Europe in the context of work to support adoptees’ individual and collective search for origins. We provide an overview of the historical and political context, and the legal arrangements that underpinned the rise of transnational adoption flows from Guatemala (1977 – 2007). We consider how adoption files operate as entry points into searches for origins and understandings of the adoption process. When read against the grain, adoption files simultaneously reveal and occlude personal histories and bureaucratic practices. They evidence entrenched, varied and sometimes haphazard practices of forgery, omission and creation. Anomaly and incongruity in the files emerge as structing devices that reveal the operations of transnational adoption shadow circuits and counterfeiting as method. For those seeking historical clarification, deciphering forgeries and irregularities entails creating new registers of legibility of the adoption papers, the adoption process and the relationalities generated through their searches.
Madre de guerrilleros, madre guerrillera: género, generación y política en dos testimonios de Carmela Pezzuti sobre la dictadura cívico-militar brasileña
Authors: Magaldi Felipe
Published: August 2023

Este artículo aborda la relación entre género, generación y política en la construcción de la memoria de la dictadura militar brasileña (1964-1985). Para ello, toma como hilo conductor dos testimonios de Carmela Pezzuti (1926-2009), funcionaria pública originaria de la provincia de Minas Gerais, que comenzó a militar en la lucha armada junto a sus hijos, Angelo y Murilo, en la década de 1960. La investigación analiza diferentes momentos de inscripción de sus memorias después de las experiencias de la prisión y de la tortura: a) en la primera sesión del Tribunal Russell II, realizado en Roma, en los años 1970, durante su exilio en Italia; b) en el libro “Compañera Carmela”, de Mauricio Paiva, publicado en los años 1990. Si, en el primer caso, el protagonismo simbólico de las madres no era expresado como parte integrante de la tarea política propiamente dicha, se verifica un cambio de acento en el segundo, ya después de los debates que conjugaron feminismo y derechos humanos en la lucha por la amnistía.
