Comparison of centralised and decentralised operational costs of multi-microgrid systems considering reliability and flexibility criteria
Authors: Abbasi Shahriar
Published: December 2024

The main purpose of formation of multi-microgrid (MMG) in both centralised and decentralised mode is to ensure the microgrid (MG) of providing load-generation balance. Minimising operational cost and maximising profit as well as more efficient and sustainable management in MMGs have been exciting research topics in recent years. However in the previous literature, an accurate and scientific comparison of centralised and decentralised MMGs has still remained as a research gap. Focusing on this gap is the main contribution of the current research; it is focused on comparison of centralised and decentralised MMGs from the operational cost viewpoint, including RESs (PV and WT), fossil fuel generators (FFG), and ESS. Moreover, the operational costs of centralised and decentralised MMGs considering reliability and flexibility criteria will be compared. The study will be done in a test power system with real specifications considering two possible scenarios. The simulations will be done in MATLAB platform using the MATPOWER package and Gurobi solver. The simulations results show that total daily operational cost of centralized MMGs is notably less than this cost in decentralized MMGs. Demand response become better when the MMGs are centrally scheduled. Also the reliability criterion of EENS is less, i.e., the power system becomes more reliable with centralized MMGs. Power losses in centralized MMGs decrease, but the CO2 emission increases.
An Enhanced Adaptive Inductance Estimator for Predictive Current Control Strategy of Grid-tied Inverters
Authors: Li Yanyan , Liu Zhenkun , Guo Leilei , Wu Zhenjun , Wang Yanfeng
Published: December 2024

This article proposes a new adaptive inductance estimator based on a full-order sliding mode virtual flux observer (FOSVFO), dedicating to improve the parameter robustness of predictive current control (PCC) strategy for grid-tied inverters (GTIs). First, the drawback of the sensitivity to grid frequency deviation of the conventional FOSVFO-based inductance estimator is analyzed, and a complex-coefficient filter is creatively introduced to filter the grid voltage. Then, the filtered grid voltage and the observed virtual flux are utilized to design inductance estimator to counteract the effect of frequency deviation. Second, an inductance adaptive law is deduced by a newly designed Lyapunov function, which ensures the inductance estimator operates well with zero active power, overcoming another drawback of the conventional FOSVFO-based inductance estimator. Based on the proposed adaptive inductance estimator, the performance of the PCC for GTIs is improved significantly. Comparative experiments validate the effectiveness and superiority of the proposed techniques.

Published: December 2024

To enable rapid detection of golden snub-nosed monkeys in complex environments, reduce the human costs associated with tracking and observing these monkeys, and accelerate the development of intelligent forest monitoring, we propose the PCB-YOLOv5n-prune model. This model is designed for lightweight devices and is based on channel pruning and module reconstruction. First, we constructed a dataset that combines annotations of the golden snub-nosed monkey's face and body, with some data converted to grayscale. We mixed and expanded five data styles to decrease reliance on color and enhance the informational content. Next, we applied the Sparse Group Lasso selection operator method to slim down the YOLOv5n primitive model for golden snub-nosed monkey detection, improving the detection speed of the underlying network. We then introduced a lightweight convolutional module, PConv, to create the improved residual branching module, CPB, which reduces model computation and memory access. Additionally, we incorporated a lightweight attention module, ECA, to adaptively weight channel features, facilitating local cross-channel information interaction. Finally, we integrated the ByteTrack multi-target tracking algorithm to enable continuous tracking of golden snub-nosed monkeys and visualize detection results. Experimental results demonstrate that the PCB-YOLOv5n-prune model reduces the number of parameters, floating point operations, and model weight by 61 %, 56 %, and 55 %, respectively, compared to the original YOLOv5n model, while significantly improving detection speed.
Religious and Political Reforms of Emperor Mimaki. Part 3: New High Priest of Miwa and Arrangement of Yamato Cults
Authors: Surowen Dmitry A.
Published: December 2024

The religious and political reforms of the early Yamato period remain largely understudied in Russian historical science. This article describes the cult standardization and the changes of the Miwa high priesthood that took place during the reign of Emperor Sūjin, also known as Emperor Mimaki (Sujin, 324–331 AD [corrected chronology]). The High Priestess of the Miwa shrine was substituted by High Priest Ō-tata-neko (ancient Jap. Opo-tata-neko); the High Priestess of the Yamato patron god Yamato-no kunitama was replaced by Ichishi-no Nagaochi (ancient Jap. Nagawochi) in the Yamato-no kunitama-no jinja shrine. The research included detailed genealogical information about the family tree of Ichishi-no Nagaochi and Ō-tata-neko, as well as about the descendants of Ō-tata-neko. Ichishi-no Nagaochi belonged to the Yamato-no kuni-no miyatsuko clan of Yamato governors, who descended from the youngest son of Toyotama-hiko of Toyotama, the Tsushima islands. The name of the latter was Furu-tama-no Mikoto, and he belonged to the Azuma-no muraji clan of priests of the sea god Watatsumi, who were maternal relatives of the founder of the Yamato dynasty, i.e., Emperor Jimmu (301–316 AD [corrected chronology]). Ō-tata-neko was a relative of Jimmu’s second wife Isuzu-hime, who came from a family of Koto-shiro-nushi priestesses (possibly a branch of the family of Ō-mono-nushi priestesses): he was a great-grandson of her older brother Ama-hikata-kushi-hikata. The noble lineage gave Ō-tata-neko the opportunity to compete for supremacy in the Ō-mono-nushi cult with princess Yamato-totohi-momoso-bime, the daughter of Emperor Kōrei. As a result, the Priestess Princess was replaced by a High Priest. The article also described the process of territorial arrangement of Shintō shrines in the newly united Yamato state.
Pentecostalism and Charismatic Movement in Russia in 1991–2020
Authors: Miazin Nikolai A.
Published: December 2024

Pentecostalism is one of the world’s most numerous branches of Protestantism. It emerged in the United States in 1906 and began to spread to the USSR in the 1920s. Pentecostalism presupposes baptism of the Holy Spirit and miracles in the mundane. At the time of the collapse of the USSR, Pentecostalism was less popular in Russia than in Ukraine and Belarus. As a result of the long isolation, most Russian Pentecostal churches maintained the religious culture that had not changed since the 1950s. They embraced foreign missionaries in the early 1990s in an attempt to catch up with the social changes. The centralization of Russian Pentecostals was brought about by the changes in religious legislation. New congregations had to join larger congregations to get an official registration. Classical Pentecostals united into the Russian Church of Christians of the Evangelical Faith, and the charismatic churches united into the Russian Union of Christians of the Evangelical Faith; both became independent from international organizations. Unregistered churches retained their supranational character: the United Church of Christians of the Evangelical Faith included communities throughout the post-Soviet space. In the 2000s, Pentecostal churches launched a lot of social projects, primarily in the field of rehabilitation. They had more rehabilitation centers for alcoholics and drug addicts than the Russian Orthodox Church. The number of Pentecostals grew 13 times in 30 years, reaching 280,000 adult members. The rapid growth could be explained by the active social activities and the belief in miracles. In addition, Pentecostals have always been active missionaries: they see it as their mission to convert relatives and friends to their faith. The main factors hindering the development of Pentecostalism in Russia are the social secularization and the strong link between Orthodoxy and the national identity. As a result, children of Pentecostal parents are the main source of replenishment for Pentecostal congregations, which is a serious obstacle for the spread of Pentecostalism in Russia.
Forms and Methods of Digitalization in Russia’s Fuel and Energy Sector between XX and XXI Centuries
Authors: Solovenko Igor S. , Rozhkov Anatoly A. , Pinzhin Kirill A. , Zholbin Andrey P.
Published: December 2024

The article offers an interdisciplinary approach to the study of digitalization in the sphere of fossil fuel business between XX and XXI centuries. This economic sector has always resisted changes, which makes the research relevant both scientifically and technologically. The authors applied the theory of modernization to analyze the key forms and methods of digitalization as part of the innovative movement in the Russian economy that took place in the early 2000s. The comparative analysis made it possible to identify the patterns behind the economic, scientific, and technical development model, including individual segments and industries. The research revealed the causes and factors that guided the processes of automation, informatization, and computerization in the domestic fuel and energy complex, also in the intersectoral context. The analysis made it possible to describe the role of the state and the business in this process. The digitalization was more active in informatization and computerization. As the scientific and technological leadership passed on from the gas industry to the oil industry, the coal mining failed to achieve technological parity by 2010. The extensive methods of implementing digital solutions, which prevailed in the 1990s and early 2000s, gave way to intensive ones. It took fuel and energy enterprises 20 years to shift from occasional automation, informatization, and computerization to a comprehensive digital transformation. The latter resulted in innovative products in other industries. As Russia’s energy security strengthened, the digital support grew more and more dependent on foreign software and hardware.

Published: December 2024

Rainfall is one of the most important meteorological phenomena since it provides water to the Earth's surface, which has a significant impact on the daily life of human beings. Gaining the knowledge of its behavior in a semi-arid basin is an important and challenging task to take advantage of this natural resource, given that water is usually scarce in such regions. Artificial intelligence and machine learning algorithms help to identify rainfall patterns and trends within a region. Multiple linear regression, random forest (RF), support vector machine, and artificial neural network (ANN) algorithms were implemented using daily rainfall data from climatological stations located within the basin using one station as a predictor variable and the remaining ones as input variables. The metrics to evaluate the model were the coefficient of determination (R2), mean absolute error, root mean square error, and the Kling–Gupta efficiency coefficient. The results showed that the daily rainfall prediction is better individually than overall, finding that the models obtained by RF and ANN simulate better daily rainfall in the basin.
Assessment of water quality of the Narmada River (India) using the fuzzy water quality index method
Authors: Rahi Dal Chand , Chandak Rajeev , Vishwakarma Amit
Published: December 2024

This study aims to assess the water quality of the Narmada River utilizing the fuzzy water quality index (FWQI) method. In this context, samples of water were gathered from six stations for various parameters such as turbidity, pH, DO, BOD5, TDS, TSS, COD, EC, TH, TA, and chloride from 2017 to 2022. Due to contamination from urbanization, water quality assessment has become essential. To address this requirement, the water quality index (WQI) was developed which incorporates various water quality parameters and expresses total water quality into a single value. Nowadays, a new method, the FWQI has been developed. To develop FWQI, 11 inputs, single output, Mamdani method, And operators, fuzzy inference rules, and centroid methods for defuzzification have been used. The average values of FWQI at the first, second, third, fourth, fifth, and sixth stations were 61.28, 57.66, 62.18, 61.90, 50.00, and 49.96, respectively. Meanwhile, the average values of WQI for the same stations were 57.98, 57.40, 58.97, 58.85, 48.39, and 49.03. The findings from both methods revealed that water quality was poor at the first four stations and good at the last two stations. This new index could serve as an alternative approach to assessing water quality.
“Por que os alunos não aprendem o que os professores ensinam?”: retomando a questão de Allwright no contexto de aprendizagem de uma linguacultura-alvo
Authors: Da Silva Amorim Marcelo , Peixoto Barbosa Ricardo Alexandre
Published: December 2024

Neste artigo, retomamos a questão apresentada por Allwright (1984a) – “Por que os alunos não aprendem o que os professores ensinam”, que coloca em evidência a disparidade entre o que é ensinado pelo docente e o que é pretensamente aprendido pelo estudante, buscando acrescentar nova perspectiva e possibilidade de interpretação das dificuldades inerentes à relação ensino-aprendizagem. Para tal, adotamos como aporte teórico Schumann e Schumann (1977); Allwright (1984a; 1984b); Ellis (1995); Larsen-Freeman (2000); Allwright e Pompeu (2003); Bell (2003); Prabhu, Castelo Branco e Claus (2003); Lightbown e Spada (2006); Krashen (2009); Franco e Almeida Filho (2015); e Almeida Filho (2018a; 2018b), dentre outros. Como resultado preliminar, prevemos que os alunos de línguas não aprendem o que os professores ensinam por conta de dificuldades na conceituação, gestão e mediação de oportunidades de interação verdadeiramente promotoras da aprendizagem.
Amefricanidade em Catacumbas de Sol, de Élie Stephenson
Authors: Ramos da Silva Liliam , De Farias Azevedo Maikele
Published: December 2024

Este artigo examina a obra Catacumbas de Sol ([1979] 2022) do guianense Élie Stephenson, destacando como o poeta constrói e expressa a identidade cultural da Guiana Francesa bem como estabelece diálogos identitários interamericanos em sua poesia. Considerando o contexto sociopolítico e cultural do território, o estudo analisa como Stephenson utiliza elementos linguísticos, temáticos e simbólicos para retratar as experiências, as lutas e as aspirações do povo guianense. O artigo investiga como sua poesia aborda questões como a herança africana, a diversidade étnica, as violências da colonização e os desafios da independência, além da busca por uma identidade nacional cujos atravessamentos coloniais reportam a metrópole como modelo identitário. Por meio de uma análise crítica de poemas selecionados com base nos referenciais teóricos de Lélia Gonzalez (1988) sobre amefricanidade, de Stuart Hall (2003, 2006) sobre identidade e de Dennys Silva-Reis (2021) sobre identidade e literatura da/na Guiana Francesa, este estudo busca compreender o papel da poesia de Stephenson na celebração da identidade guianense.

Published: December 2024

O presente estudo objetivou investigar o tratamento pedagógico dado à seleção lexical em videoaulas para o ensino de língua portuguesa. Direcionamos nossa atenção nas práticas de produção de videoaulas, com foco na seleção vocabular, uma vez que estas assumiram um papel de destaque no cenário pedagógico de nosso país, principalmente em virtude da reorganização metodológica que o ensino experienciou, considerando a pandemia do Covid-19. Assim sendo, nossa pesquisa pode ser caracterizada como documental, aplicada e de finalidade interpretativo-descritiva. O percurso metodológico desenvolvido iniciou pela catalogação de cinco videoaulas, distribuídas em quatro canais educativos on-line, dois em plataforma própria e dois na plataforma YouTube, e, posteriormente, sua interpretação. Para a análise dos conteúdos, pautamo-nos nas contribuições teóricas de Neves (2020), Antunes (2012), Bezerra e Reinaldo (2020), Rocha (2008) e Freire (2015). Por fim, diante dos resultados obtidos, constatamos o trabalho da seleção lexical com os critérios de adequação ao tema, propósito, leitor/ouvinte, gênero textual e contexto. Esses objetos se organizam no eixo de ensino do léxico voltado para o funcionamento textual-interativo dos itens lexicais. Com relação às perspectivas de análise linguística, verificamos que a maior parte das ocorrências estão alinhadas às tendências inovadora e conciliadora.
Monsieur Pain e Amuleto, narrativas fractais de Roberto Bolaño
Authors: Alves Teixeira Hiago , De Oliveira Lima Samuel Anderson
Published: December 2024

Este artigo tem por objetivo explorar a ideia de uma narrativa fractal, desenvolvido por Ignacio Echevarría (2008), a partir de dois romances de Roberto Bolaño, Monsieur Pain (1999a) e Amuleto (1999b). Conceito retirado da geometria pós-euclidiana, o fractal também foi desenvolvido como categoria de análise cultural por Omar Calabrese (2006) que o descreverá como um “polígono monstruoso”. Neste trabalho, partiremos dessa ideia para desenvolver uma reflexão sobre a forma particular com que os romances de Bolaño são arquitetados, partindo de autores como Paul Ricoeur (2012), Frank Kermode (2023) e Jacques Rancière (2021) para refletirmos sobre as mutações da ficção na contemporaneidade e de como seria possível observar a característica fractal na obra do autor chileno.
“O fardo da língua inglesa”: uma análise do discurso salvacionista da Embaixada dos EUA à luz do sistema de avaliatividade
Authors: Abreu Diego
Published: December 2024

O objetivo precípuo deste estudo é gerar entendimentos sobre o discurso salvacionista em torno da língua inglesa produzido pela Embaixada brasileira dos EUA em sua conta do Instagram. Partindo de uma perspectiva que aproxima o salvacionismo discursivo da prática imperialista, a fundamentação teórica do presente estudo possui três pilares estruturantes: uma discussão em torno das noções clássicas e contemporâneas de imperialismo (LÊNIN, 2008), uma reflexão sobre o conceito de salvacionismo (VAUGEOIS, 2007) e uma revisão histórica da trajetória imperialista dos EUA (HOPKINS, 2018). Os dados selecionados são examinados com o apoio do ferramental analítico do Sistema de Avaliatividade (MARTIN; WHITE, 2005), braço sobressalente da Linguística Sistêmico-Funcional (HALLIDAY, 1994), que categoriza e mapeia os expedientes avaliativos ofertados pela linguagem. As análises realizadas iluminam os recursos e estratégias retóricas empregados no processo de construção discursiva do salvacionismo imperialista em torno da língua inglesa, evidenciando o papel de proa desempenhado pelos elementos valorativos nesse empreendimento.
Análise de uma interação argumentativa no TikTok: o caso da controvérsia entre Felipe Lopes e Ingred Silveira sobre o racismo reverso
Authors: Aboboreira Ana Débora Cruz , Piris Eduardo Lopes
Published: December 2024

Neste artigo, analisamos dois vídeos publicados no TikTok que refutam o discurso do racismo reverso e exploramos a relação constitutivamente dialética da argumentação por meio do exame de suas dimensões discursiva, lógica e enunciativa. O quadro teórico assume a perspectiva interacional da argumentação (Plantin, 1996; 2008; 2011), para ressaltar a oposição entre discurso e contradiscurso coconstruída a partir de uma controvérsia pública. O corpus constitui-se de dois vídeos do influenciador digital Felipe Lopes, publicados em 2022 no TikTok, como respostas contradiscursivas ao discurso da influenciadora digital Ingred Silveira favorável ao racismo reverso. A metodologia de análise recorre ao modelo de Padilla, Douglas e López (2011), por ser um modelo integrador de análise argumentativa que considera a perspectiva interacional da argumentação. Os resultados revelam que as estratégias de refutação ao discurso do racismo reverso articulam (1) a atribuição a si da imagem de especialista, (2) a justificação da tese com os esquemas argumentativos de regra, de sinal e de autoridade e (3) a construção de um tom assertivo para projetar grau de certeza à sua enunciação. Outro achado da pesquisa é o levantamento da hipótese de que as interações argumentativas no TikTok (e talvez em mais outros ecossistemas digitais) não se encaixam na concepção prototípica de interação argumentativa postulada na literatura, pois não se caracterizam como monogeridas nem como poligeridas, mas sim num continuum entre dois polos.
O julgamento do inelegível: uma análise dialógica de comentários online em posts da página Sensacionalista
Authors: De Oliveira Silva Nara Karolina , Pinheiro Guerra Zailton , Alves dos Santos Bernardino Rosângela , Rocha Bessa José Cezinaldo
Published: December 2024

Neste trabalho, objetivamos analisar as relações dialógicas e os posicionamentos axiológicos expressos em comentários online de posts da página Sensacionalista sobre o julgamento de inelegibilidade do ex-presidente da república brasileira, Jair M. Bolsonaro. Temos como ancoragem teórica central as ideias de Bakhtin (2011; 2016) sobre linguagem, gênero discursivo e relações dialógicas, de Volóchinov (2017; 2019) sobre posicionamentos axiológicos, bem como os estudos que versam sobre comentários, tais como Recuero (2012), Alves Filho e Santos (2013), Bertucci e Nunes (2017). Metodologicamente, a pesquisa adota uma abordagem qualitativa, de natureza descritiva e interpretativa dos dados. O corpus é constituído por 461 comentários, dos quais 10 ilustram o nosso empreendimento investigativo, selecionados de dois posts da página Sensacionalista, no Instagram, sobre o julgamento de inelegibilidade de Bolsonaro. A análise aponta que os comentários refletem a polarização ideológica existente no país, com os internautas defendendo suas convicções e confrontando seus adversários, muito empenhados em reproduzir os posicionamentos que acreditam ser verdadeiros. Os resultados indicam, portanto, que o espaço de publicação dos comentários online costuma configurar-se em um ambiente de relações dialógicas propício ao confronto de posições axiológicas e de diferentes perspectivas de sentidos.
A categorização referencial como recurso de impolidez no Twitter/X
Authors: Adorno Marciotto Oliveira Ana Larissa , Ximenes Cunha Gustavo , Vieira Miranda Monique
Published: December 2024

Neste trabalho, propomos um estudo do papel da categorização referencial como um recurso de que os usuários do Twitter/X se valem para exercitarem impolidez linguística. Na perspectiva que adotamos, entendemos a referenciação, tal como definida no âmbito da Linguística textual, como um processo sociocognitivo em que os recursos verbais surgem como os responsáveis pela coconstrução de versões públicas do mundo, versões que, de forma reflexiva, podem ser objeto de disputa, acordos e ajustes pelos próprios interlocutores. Especificamente, centramo-nos na descrição e na análise de insultos e/ou de xingamentos que ocuparam a posição temática em um corpus formado por 300 tweets utilizados para atacar figuras do cenário político. Esses insultos foram dirigidos a líderes políticos e/ou a seus aliados, e publicados em postagens que comentavam o debate eleitoral do segundo turno das eleições brasileiras, ocorrido em 28 de outubro de 2022, e transmitido pela TV Globo. Como resultado, foi possível reunir em quatro categorias principais as expressões por meio das quais nos tweets os autores categorizam figuras políticas: A) epítetos relacionados a personagens históricos ou da grande mídia; B) cunhagem de termos inovadores; C) insultos atacando a honestidade e/ou a moral do candidato ou de apoiadores; D) insultos atacando o equilíbrio psicológico do candidato no debate.
SIGNS, LANGUAGE AND KNOWLEDGE IN AUGUSTINE’S DE MAGISTRO

SIGNS, LANGUAGE AND KNOWLEDGE IN AUGUSTINE’S DE MAGISTRO
Abstract:
In his dialogue De Magistro, Saint Augustine debates whether one human being can teach another something using language. For this purpose, he develops his semantics and a general semiotic theory. The first and minor objective of the paper is to show that Wittgenstein’s (1953) Augustinian conception of language applies to Augustine’s semantics. The second and major objective is to show that his skeptical conclusion is epistemic and derives from his strong requirements for justification. For Augustine knowledge requires acquaintance with the epistemic objects. In the case of sensible knowledge, justification consists of first-hand acquaintance; in the case of intellectual knowledge, it consists of understanding thanks to divine illumination.
Keywords:
Saint Augustine, Augustinian conception of language, Teaching, Significabilia.
Construyendo un puente: Una propedéutica heideggeriana para el establecimiento de una pre-ciencia.
Authors: Gilabert Fernando
Published: December 2024

Con relativa frecuencia el pensamiento de Martin Heidegger es presentado como el de un crítico exacerbado contra la ciencia. Esa crítica es puesta bajo sospecha por su participación política en el nacionalsocialismo y es tachada, en muchos casos sin fundamento alguno, de reaccionaria, de suponer un paso atrás en la línea del progreso. Sin embargo, el propio Heidegger muestra que no hay nada más alejado de la realidad: Su pretensión no es anular la ciencia, sino reconducirla, servir de faro para todas las ciencias, sin distinción entre ciencias de la naturaleza y ciencias del espíritu. El propósito heideggeriano es establecer una suerte de pre-ciencia que sirva para orientar a todas las ciencias (sean de la naturaleza o del espíritu). Este estudio pretende exponer como esa pre-ciencia sirve de guía para la ciencia y como puede convertirse en un puente que sirva para unir las dos orillas de la ciencia.

Devido à alta demanda energética mundial e os problemas ambientais derivados da queima de combustíveis fósseis, a sociedade atual lança-se na busca por novas fontes de energia mais sustentáveis, com destaque para a biomassa, merecendo especial atenção as microalgas. Além de fornecer metabólitos essenciais para a produção de biocombustíveis, as microalgas podem ser cultivadas em painéis fotovoltaicos, obtendo energia solar através da fotossíntese. Apesar do grande número de pesquisas, a obtenção de biocombustíveis de microalgas ainda esbarra em algumas limitações. O presente estudo busca avaliar a viabilidade técnica e econômica do uso de microalgas como matéria prima para obtenção de energia, além de apresentar alternativas para superar as limitações do processo.
Avaliação do impacto na redução de poluentes através da implantação de um Corredor de GNV no Maranhão
Authors: Barbosa Luciana Pereira
Published: December 2024

Este estudo investiga o impacto da substituição do diesel pelo Gás Natural Veicular (GNV) na redução de poluentes no estado do Maranhão. A pesquisa destaca a significativa diminuição nas emissões de gases de efeito estufa (GEE) e poluentes locais, como monóxido de carbono (CO), dióxido de carbono (CO2) e hidrocarbonetos não metano (NMHC). Com base na análise de dados do Sistema de Estimativas de Emissões e Remoções de Gases de Efeito Estufa (SEEG), foi possível quantificar a redução de aproximadamente 3g/km de CO2 ao substituir o diesel pelo GNV. Além disso, uma infraestrutura de postos de abastecimento de GNV é proposta, com base na previsão de fornecimento para o segundo semestre de 2024, é mapeada e analisada. Este estudo reforça a importância de políticas de incentivo ao uso de GNV para promover um transporte mais sustentável e menos poluente no Maranhão.

Published: December 2024

No Brasil, em especial na região Nordeste, existe uma grande quantidade de reservatórios de óleos pesados, onde a recuperação pelos métodos convencionais mostra-se ineficiente. Neste cenário, a recuperação térmica, particularmente a injeção de vapor, tem sido largamente empregada, considerando que o calor reduz a viscosidade do óleo, facilitando seu deslocamento de forma significativa. Este trabalho tem como objetivo apresentar um estudo da análise econômica da injeção de vapor em poços de petróleo a partir da água produzida. Para utilizar a água produzida como vapor na recuperação dos óleos pesados é necessário um tratamento para retirada dos contaminantes, onde foi proposto um sistema de tratamento adequado para este uso. O estudo foi realizado no campo de Araçás BA, onde foi analisado uma hora de operação de injeção de vapor a partir de uma água fornecida pela rede de abastecimento local, para desobstrução de um poço produtor, devido a precipitação de parafina ao longo da coluna de produção. Diante deste fato, foram analisados os custos relacionados e os benefícios da utilização da água produzida como fluido, tanto para processos como esse, quanto para recuperação dos óleos pesados.
Alocação e dimensionamento ótimos de subestações elétricas por meio do algoritmo de busca corvo
Authors: Paixão Matos Arthur do Carmo , Bravin Donadel Clainer
Published: December 2024

O aumento contínuo na demanda global por energia elétrica tem gerado um significativo impulso no setor energético em escala mundial. Conforme destacado no relatório mais recente da International Energy Agency (2022), a demanda por energia elétrica em 2021 alcançou a marca expressiva de 24.700 TWh, apresentando um crescimento de 6% em relação ao ano anterior, representando o maior incremento desde 2010. Este contexto tem enfatizado a necessidade de um sistema de distribuição de energia elétrica robusto e confiável, que possa atender a essa crescente consumo sem comprometer o serviço por possíveis inadequações do sistema. Dessa maneira, este artigo propõe uma nova abordagem para enfrentar o desafio da alocação e dimensionamento de subestações elétricas em sistemas elétricos de distribuição, baseada na inteligência dos corvos, por meio do algoritmo de otimização Crow Search Algorithm (CSA). Além disso, o método desenvolvido também organiza a conexão das subestações elétricas aos centros de carga. O objetivo central é a minimização dos custos globais do projeto de alocação e dimensionamento de subestações elétricas, considerando um conjunto de objetivos e restrições técnicas e operacionais. Os testes na metaheurística foram realizados em um sistema elétrico de distribuição apresentado na literatura, que possui 38 centros de carga e 6 subestações elétricas já existentes, que permitiu estabelecer diferentes cenários de aplicação do método. Dessa forma, o CSA se mostrou um método promissor de aplicação no problema de alocação e dimensionamento de subestações elétricas.
Understanding Primary Endometrial Squamous Cell Carcinoma: A Narrative
Analysis
Authors: Kumar Naina
Published: December 2024

Primary Endometrial Squamous Cell Carcinoma (PESCC) is a rare variant of endometrial carcinoma accounting for <1% of all endometrial
malignancies. It is a highly aggressive tumor and carries a very poor prognosis with a 5-year survival reaching up to zero. The exact pathogenesis
of PESCC is unclear, and different theories have been proposed for its origin. The most widely accepted theory proposes the endometrial squamous
metaplasia, progressing to dysplasia and frank squamous cell carcinoma. The role of human papillomavirus infection in its pathogenesis is
controversial. The present review aims to brief the clinical features, pathogenesis, diagnosis, and management of PESCC. The literature was
searched from March 2003 till April 2024 using different databases like PubMed, SCOPUS, and EMBASE and many English peer-reviewed
journals. The following search terms were used: “Primary endometrial squamous cell carcinoma,” “Pathogenesis of PESCC,” “Ichthyosis uteri and
PESCC,” and “Management of PESCC.” PESCC is a rare endometrial malignancy, and very few cases have been reported in the literature. The
overall prognosis of the disease is poor, and management includes total hysterectomy with lymph node resection followed by chemoradiotherapy,
depending on the stage of the malignancy.

Parkinson’s disease (PD), a leading movement disorder, is instigated due to
the progressive apoptosis of dopaminergic neurons in the substantia nigra pars
compacta and due to exhausted levels of dopamine in the striatum of the brain.
Currently, all treatments available for PD are palliative rather than curative.
Researchers are still investigating the complex interplay of genetic and environmental
factors that contribute to the development of PD. Natural product's renaissance is due
to their ability to target multiple molecular pathways involved in the disease, as well as
due to fewer side effects. A diterpenoid lactone compound, andrographolide, is found
in the plant Andrographis paniculata and is commonly used in traditional medicine to
treat various ailments. It has been discovered to have numerous biological activities,
including antioxidant, anti-inflammation, anticancer, and neuroprotective effects. In
preclinical studies, andrographolide has been shown to have neuroprotective effects in
animal models of PD due to its high antioxidant potential, which can help reduce the
impact of inflammation in the brain, and its ability to promote the survival and growth
of dopaminergic cells. Several structural analogs of andrographolide have been studied
for neuroprotective effects, including 14-deoxy-11-oxoandrographolide, 14-deoxy-11,
12-didehydroandrographolide (DDA), and 14-deoxy andrographolide (DA). Both DDA
and DA are analogs of andrographolide that have been shown to have neuroprotective
effects in animal models of PD disease. DDA is more potent than andrographolide in terms of neuroprotection. The anti-inflammatory and antioxidant properties of 14-
deoxy-11, 14-deoxy-11, 12-didehydroandrographolide-19-oic acid (DDAA), and 7--
-Methyl-andrographolide were found to be more potent than andrographolide. On the
other hand, andrographolide derivatives, such as 14-deoxyandrographolide,
andrographolide epoxide, and andrographolide sulfonates possess potent antiinflammatory and anticancer properties. Given that andrographolide and its structural
analogs and derivatives have substantial therapeutic potential and have been proven to
be neuroprotective, we intend to highlight this promising compound's role in PD
disease.

One of the most common cancers in males is prostate cancer, which
frequently appears later in life after 65 years. Prostate cancer is the second most
frequent disease in men globally, according to the World Health Organization (WHO),
with 1.3 million new cases identified in 2018. Although the composite molecular
mechanisms that cause prostate cancer are still not fully understood, certain important factors have been identified. These include mutations in the androgen receptor gene
and the tumor suppressor gene known as prostate cancer gene 1 (PCA1) or “BRCA1”,
which are linked to prostate cancer. Furthermore, overproduction of prostate-specific
antigen (PSA) and changes in the concentrations or functions of particular proteins,
such as cyclin-dependent kinase 4 (CDK4), function as indicators of prostate cancer
and aid in its progression. Age, family history, ethnicity, food, obesity, and exposure to
specific chemicals and hormones are risk factors. Depending on the stage of the disease
and the patient's general condition, the main treatment options for prostate cancer
include surgery, radiation therapy, hormone therapy, chemotherapy, immunotherapy,
and active surveillance. Examining several strategies, natural products—especially
those derived from plants—have shown signs of having anti-cancer qualities and are
being researched as possible treatments for prostate cancer. Among these,
andrographolide—a diterpenoid lactone compound—has attracted attention. It is
extracted from the leaves of the Andrographis paniculata plant, traditionally used in
Chinese and Ayurvedic medicine. Andrographolide and its analogs are being studied
for their potential to treat a variety of malignancies, including prostate cancer, due to
their well-known pharmacological actions, which include anti-inflammatory,
anticancer, antiviral, and antioxidant qualities. Studies show that they have
antiproliferative, pro-apoptotic, and antimetastatic properties in animal models and
prostate cancer cell lines, suggesting they may be a valuable treatment for prostate
cancer.

Lung cancer refers to the changes in the lung tissue and cells that lead to
cancer growth due to gene mutations and cellular changes that result in uncontrollable
cell growth and division. However, the exact pathophysiology of lung cancer is not yet
fully understood. It is a significant cause of mortality worldwide and can be divided into two main types: small-cell lung cancer (SCLC) and non-small-cell lung cancer
(NSCLC). The specific subtypes of NSCLC are adenocarcinoma, large-cell carcinoma,
and squamous cell carcinoma. Risk factors for lung cancer include exposure to radon,
smoking, air pollution, and a family history of lung cancer. Symptoms may include
shortness of breath, chest pain, coughing, and weight loss. Early detection and proper
treatment, including chemotherapy, radiation therapy, surgery, and targeted therapy,
can improve the prognosis and survival rates. However, the deaths and the cases of
lung cancer are constantly rising. This increases the need for potential drug treatment
for lung cancer. Among the various available sources for identifying novel therapies for
multiple diseases, such as cancer, medicinal plants and plant-derived compounds play a
significant role. In addition, several studies revealed that Andrographis paniculata and
its derived compounds have shown various pharmacological effects, including anticancer effects. Recently, andrographolide and its structural analogs have also gained
attention in lung cancer due to their unique potential. Studies have shown that
andrographolide and its analogs can restrict the development of lung cancer cells via
the induction of apoptosis, a programmed cell death. They have also been shown to
target specific signaling pathways that play a role in the development and progression
of lung cancer, including the NF-kB and MAPK pathways. Additionally,
andrographolide and its analogs have been shown to exhibit low toxicity, making them
attractive as potential therapeutic agents for the treatment of lung cancer. Additional
investigations are required to thoroughly understand these compounds' mechanisms of
action and potential clinical applications in lung cancer treatment. In summary,
andrographolide and its structural analogs have shown promising results in both in
vitro and in vivo studies as potential therapeutic agents for lung cancer treatment. Their
anti-cancer properties, including inhibition of cancer cell growth and induction of
apoptosis, make them of significant interest for further research.

Myocardial infarction is a sudden and fatal disease that causes a significant
number of deaths in the world. The current treatment strategy for MI is only for
symptomatic relief and cannot cure or reverse the disease condition. Hence, there is a
need to identify novel, definitive, and minimal toxic drugs to treat MI. Phytochemicals
always draw attention as an alternative and upgraded choice to combat various
ailments. Photochemical compounds are non-nutritive biologically active secondary
metabolites abundantly found in plants. Andrographolide and its derivatives obtained
from a medicinal herb, Andrographis paniculata, are broadly utilized in traditional
medicinal systems to treat various diseases, including cardiovascular diseases. In the
present chapter, we explore andrographolide and its derivatives for its cardioprotective
potential both in vitro and in vivo. Andrographolides show their cardioprotective
potential by demonstrating multiple mechanisms, including ERK1/2 inhibition
associated with anti-platelet action, PI3K/Akt pathway-associated inflammation
inhibition, and activation of Nrf-2/HO-1pathway-associated antioxidant mechanism.
Cardioprotection of andrographolide and its derivatives are shown by various animal
models' anti-arrhythmic, antihypertensive, anti-inflammatory, and antioxidant mechanisms. In this way, andrographolide and its derivatives can offer a better choice for
developing a novel therapeutic molecule for myocardial infarction.
