An optoelectronic system for controlling a direct current motor
Authors: Syroka Zenon 
Published: December 2022

An optoelectronic system for controlling a direct current (DC) motor is presented in Part 1 of the article. The software for the designed motor is described in Part 2. A system for processing data from an infrared transmitter was built. The project was upgraded in successive stages of development, and it ultimately evolved into a small computer with a motor controller. The designed system automatically adjusts the motor’s rotation and speed. The user is tasked only with conveying operational commands. The entire system is based on a single microcontroller. The designed optoelectronic system receives user commands (the program can be modified to support free-space optical communication networks conforming to all communication standards). The system activates the motor, counts the number of rotations and adjusts the motor’s position. The designed system operates on the following principle: the user sends commands to the motor via a remote control with an infrared diode. The keys on the remote control have been programmed with different commands. The transmitted data are processed by the system which activates the motor and sets the desired motor speed. The task is completed, and the system is ready to process the next command. If the number of rotations differs from the preset value, the motor’s position is adjusted. If the physical position of the rotor axis is altered, the system corrects the offset to the last programmed position. The designed system can be easily adapted to various types of motors and IR controllers.
Revolução e democracia: o eurocomunismo no Brasil, no crepusculo da ditadura militar
Authors: Said Ana Maria 
Published: December 2022

Pretendemos nesse trabalho resgatar a unidade e o marxismo de Antonio Gramsci, a coerência de análise, mesmo nos fragmentos dos seus Cadernos, a constância dos temas retomados em um contexto unitário profundo, para compreender o retrocesso orgânico que estamos vivenciando no Brasil atual e na América Latina como um todo.
Uma parcela da chamada esquerda brasileira é influenciada pelo marxismo de Antonio Gramsci, utilizando-se de suas categorias para interpretar a realidade brasileira, conceitos esses que sofreram interpretações diversas, desviando-se muitas vezes da formulação gramsciana.
Carlos Nelson Coutinho é o principal divulgador e tradutor das obras gramscianas em nosso país. Havia também um grupo de renovadores no Partido Comunista Brasileiro (PCB), os chamados gramscistas, no início da década de 1980, que traduzem Gramsci e se utilizam de seus conceitos para analisar a realidade brasileira e assim propor uma “nova” estratégia para o Partido.
O marxismo brasileiro rompia com o stalinismo no campo filosófico e na sociologia da cultura, mas não no campo político. Por outro lado, com o início da década de 1980, o gramscismo no Brasil tem como interpretação a orientação do Partido Comunista italiano, defendendo a democracia como estratégia e analisando-a como um valor universal, conforme orientação de Enrico Berlinguer, chefe do partido italiano.
Estudaremos o debate que ocorre em 1980, no interior do PCB, discutindo estratégia e democracia, o que faremos para avaliar uma questão de práxis ainda fundamental para a esquerda brasileira, os conceitos de democracia e revolução gramscianos, que é também a questão central para a esquerda contemporânea.
Para essa análise, é fundamental retornar ao marxismo de Gramsci e à sua obra, e retomar conceitos básicos de sua estratégia para a revolução comunista, o que possibilita uma análise crítica do eurocomunismo europeu e seus braços no Brasil, com as consequências atuais do recrudescimento conservador e o perigo da retomada dos grupos políticos de direita, e fascistas, em nosso país.

O ensino da história e cultura afro-brasileira através do samba
Authors: Santos Marcos Raddi dos 
Published: December 2022

O presente artigo é um estudo teórico e metodológico que busca contribuir para o trabalho com o samba no ensino de história na educação básica, principalmente no ensino da história e da cultura afro-brasileiras. Esse gênero musical, criado pela população afrodescendente nas primeiras décadas do século XX, é uma fonte histórica imprescindível para o conhecimento de sua vida, história e cultura no Brasil. Nesse sentido, configura-se também como um recurso didático e pedagógico para contar a história brasileira vista a partir de baixo, assim como para o estudo de vários processos históricos a partir da perspectiva das classes oprimidas. A metodologia empregada em nossa pesquisa consiste em um debate teórico sobre as relações entre a história, seu ensino e a música, seguido das análises de três composições com possíveis atividades didáticas. Em nossa perspectiva, trazer o samba para a sala de aula é uma das maneiras de construir uma educação antirracista, pautada em valores democráticos e igualitários.

DOĞAL KONUŞUCUNUN SES SEMBOLİZMİNE DAİR SEZGİSEL BİLGİLERİ ÜZERİNE BİR ARAŞTIRMA
Authors: AKTEKER Osman 
Published: December 2022

Ses sembolizmi, göstergelerin gösterenlerinin rastlantısal olup olmadığını araştıran bir varsayımdır. Felsefe, dil bilimi, psikoloji gibi birçok disiplin ses sembolizmi varsayımını incelemektedir. Dil bilimi ise ses sembolizmini dilin evrimini açıklayan bir varsayım olarak tanımlamaktadır. Fakat ses sembolizmi varsayımı, dil biliminde genel kabul görmemiştir. Özellikle Yapısalcı Dil Bilimi ve Üretici Dil Bilgisi, ses sembolizmi varsayımını dil bilimi çalışmalarına dâhil etmemiştir. Çünkü ses sembolizmi varsayımı, gösterenleri oluşturan ses birimleri ile gösterilenleri arasında ses ve anlam bağıntısı bulunduğunu ileri süren bir varsayımdır. Fakat bu bağıntıyı bilimsel yöntemlerle incelemek mümkün değildir.
Bu çalışma, ses ve anlam bağıntısının belirgin olduğu ve ses sembolizminin tipolojik biçimleri olan “boyut sembolizmi, biçim sembolizmi, yansıma sözcükler ve kavram sesleri”nden hareketle doğal konuşucunun ses ve anlam ilişkisine dair sezgisel dil bilgilerini ölçmeyi amaçlamıştır. Ayrıca, ses sembolizmi varsayımını tipolojik biçimlerle sınırlamış ve ses sembolizmini sözcük biliminin konusu olan bir söz yapımı aracı olarak tanımlamıştır.

Education for Whom?: Exploring Systems of Oppression and Domination
Authors: Brady Janelle 
Published: December 2022

<p>This research paper explores a plethora of issues in education by linking systemic forms of oppression and domination to historical and contemporary contexts. The main argument is an identification and articulation of the importance of historical localities in the perpetuation of people’s oppression and marginalization and the pedagogical implications of systems of oppression and domination within and beyond Canadian contexts. I move beyond highlighting deep-rooted systemic injustices by outlining the significance of deconstructing ideas of difference as a deficit by presenting many decolonial actions that are currently taking place in the Canadian K-12 educational context. Finally, I re/introduce an opportunity for further action grounded in new imaginaries and futurities. </p>
Green colonialism in Latin America? Towards a new research agenda for the global energy transition
Authors: Dorn Felix Malte 
Published: December 2022

Drawing on various empirical examples (e.g. lithium, green hydrogen, REDD+), several studies point out that the global energy transition continues to be based on the geographic externalization of labour, natural resources, and sinks. The energy transition thus increases the pressure on natural resources in Latin America and reproduces the continent’s position as the world’s raw material supplier. This is increasingly referred to as ‘green colonialism’ by (scholar) activists. Moving past a merely provocative catchphrase, in this paper, I discuss the analytical implications and value of the term green colonialism for normative political-ecological research. In so doing, it becomes evident that the coloniality of the energy transition has to be understood as a political-epistemological project. This is of particular relevance for Latin America. Embedded in the hegemonic Euro-North American-centered modernity, the energy transition advances techno-optimist solutions and reproduces patterns of thought, knowledge and action. However, it soon becomes evident that the geographies of decarbonization are significantly more complex and shaped by multiple actors, policies, and strategies. Therefore, further research is needed on the geopolitics and geopolitical economy of the energy transition, going beyond the North-South dichotomy. Resumen: ¿Colonialismo verde en Latinoamérica? Hacia una nueva agenda de investigación para la transición energética mundialA partir de diversos ejemplos empíricos (litio, hidrógeno verde, REDD+), varios estudios señalan que la transición energética global sigue basándose en la externalización geográfica de mano de obra, recursos naturales y sumideros. La transición energética aumenta así la presión sobre los recursos naturales en Latinoamérica y reproduce la posición del continente como proveedor mundial de materias primas. Los activistas (académicos) se refieren cada vez más a este fenómeno como “colonialismo verde”. Más allá de un eslogan meramente provocador, en este artículo discuto las implicaciones analíticas y el valor del término colonialismo verde para la investigación político-ecológica normativa. Al hacerlo, se hace evidente que la colonialidad de la transición energética debe entenderse como un proyecto político-epistemológico. Esto es de particular relevancia para Latinoamérica. Inserta en la modernidad hegemónica euro-norteamericana, la transición energética avanza soluciones tecno-optimistas y reproduce patrones de pensamiento, conocimiento y acción. Sin embargo, pronto se hace evidente que las geografías de la descarbonización son significativamente más complejas y están conformadas por múltiples actores, políticas y estrategias. Por lo tanto, es necesario seguir investigando sobre la geopolítica y la economía geopolítica de la transición energética, más allá de la dicotomía norte-sur.
La política del color: (des)andando los caminos de la afrodescendencia en/de la Argentina
Authors: Cirio Norberto Pablo 
Published: December 2022

A más de dos décadas del avance que significó, en Durban, para los hasta entonces llamados negros autodenominarse afrodescendientes, parte de este colectivo de/en la Argentina continúa empleando el color que dio sentido primigenio para interpelar al Estado y visibilizarse, lo que llamo política del color. Vehiculizan sus demandas mostrándose del modo en que históricamente vienen siendo representados. El Estado también abunda en esta lógica pero para neutralizar o minimizar sus demandas. Mi hipótesis es que esto es contraproducente porque reduce todo a un colorismo anodino, lo que limita el Estado atenderlos satisfactoriamente

“THE LAST PROPHET” NOVEL BY LEONID MOSENDZ: SOURCES, GENRE, STRUCTURE, IMAGE
Authors: Vasylenko Vadym 
Published: December 2022

The paper analyzes the novel “Th e Last Prophet” by Leonid Mosendz focusing on its sources, the genre nature and structure, and the genesis of John the Baptist’s image. There were objective and individual reasons for Mosendz’s appeal to the biblical myth of John the Baptist, which have been explained. Attention is drawn to problematic areas in the interpretation of the novel by Mosendz’s critics. Among the sources that the writer turned to while working on the novel were “Jewish Antiquties” by Josephus Flavius, “The Life of Jesus” by Ernest Renan, and “Christ Unknown” by Dmitry Merezhkovsky. The traces of these books are recognizable in the text of Mosendz’s novel.
“The Last Prophet” combines the elements of several genres, the most important of which are three: apocryphal, historical, and didactic. Mosendz’s work has a complex multifaceted structure. Th e novel’s three parts have their parallels with the biblical text: the Old Testament poetic model corresponds to the first part, the biographical model of the Gospels to the second, and the historical model of the Acts of the Apostles to the third. Special attention is paid to the connection of the novel to the literary biography of Joan the Baptist, an iconic figure in the European tradition. The interpretation of this image by the author is peculiar and unique to European literature. Thus, Mosendz’s “The Last Prophet” is a lengthy multifaceted epic story about John the Baptist, based on historical sources and religious texts and reproduced at high ideological and literary levels.
Outcomes of treatment for right atrial isomerism with functional single ventricle and extracardiac total anomalous pulmonary venous connection beyond neonatal period: Delayed surgical treatment, improving outcomes

Published: December 2022

ObjectiveTotal anomalous pulmonary venous connection (TAPVC) is frequently associated with right atrial isomerism (RAI), which is commonly complicated with an unbalanced atrioventricular canal with contralateral hypoplasia, complex systemic and pulmonary venous anatomy, and conotruncal abnormalities, resulting in increased risk of mortality. This study aimed to review the outcomes of delayed surgical treatment for patients with RAI complicated with functional single ventricle (FSV) and TAPVC at a single center.MethodsIn this retrospective study, we reviewed the medical records of 24 consecutive patients with RAI complicated with FSV and TAPVC who underwent initial surgical palliation after 5-month old between September 2008 and June 2019. Demographic data, concomitant anomalies, age at initial palliation, and surgical interventions were extracted and analyzed using the Cox proportional hazard model to assess risk factors for mortality and the Kaplan-Meier method to assess survival.ResultsThe in-hospital mortality was 12.5% (three out of 24). The causes of death were pulmonary arterial hypertension and low cardiac output syndrome. Average follow-up was 65.2 ± 40.3 months (7–137 months). Another 4 patients died during the follow-up due to low cardiac output syndrome, protein-losing enteropathy and pulmonary arterial hypertension, respectively. Kaplan-Meier estimated survival at 1 and 5 years were 83.1 and 69.4%, respectively. Fontan completion was 45.8% (11/24). The mortality for patients with pulmonary venous obstruction (PVO) was 66.7% (4/6). Cox multivariate regression analysis indicated that preoperative PVO was the only risk factor for mortality (p = 0.032; hazard ratio, 10.000; CI 1.222–81.811).ConclusionOutcomes of delayed surgical treatment for patients with RAI complicated with FSV and TAPVC have improved significantly. The survival and Fontan completion were higher. However, preoperative PVO was still the risk factor for mortality.

Published: December 2022

A regional investigation of precipitation extremes could help the local authorities to develop strategies against potential climatic disasters, especially in regions of large climate vulnerability. In this context, this study focused on the homogeneity and trend analysis of eleven extreme precipitation indices from a daily rainfall dataset of rain gauges of the state of Ceará, located in the north of Northeast Brazil, from 1974 to 2018 at annual and seasonal time scales. The data were first submitted to gap-filling and quality control processes. Homogeneity, trend, and correlation coefficient were performed subsequently. Homogeneity results showed that most of the precipitation series were classified as “useful.” Significant break years in the series agreed well with moderate and very strong El Niño and La Niña events, suggesting a further investigation of this possible connection. Wet and dry day precipitation indices mainly indicated a decrease in the rainfall regime and an increase in dry days, mainly in the central-eastern, northwestern, and southern regions of the Ceará, especially during the annual time scale and the rainy season. The Locally Weighted Scatterplot Smoothing (LOWESS) curve showed changes in almost all series during the 1980s and 1990s, coinciding with the homogeneity breaks and years of severe droughts that strongly hit the region. Correlation coefficients were strong and significant between rainfall total index and the other precipitation indices.
