Published: March 2024

O presente artigo é parte de nossa tese de doutorado na qual temos o objetivo de sopesar como os agentes públicos e privados se apropriaram das imagens da cidade de Salvador criadas pelo autor Jorge Amado e as ressignificaram, por meio do marketing urbano para dar um apoio institucional ao turismo. Nesse trabalho apontamos que é possível pensar a literatura como instrumento para se obter vantagens na concorrência intercidades, já que a utilização das ferramentas de marketing, importadas do universo empresarial privado, ganharam espaços nas administrações públicas.
TV INES como acontecimento discursivo
Authors: Coimbra Matheus Batista Barboza , Fragoso Élcio Aloisio
Published: March 2024

A TV foi uma web TV criada para promover a acessibilidade linguística para sujeitos surdos. Essa possuía uma programação bilíngue em Libras e Língua Portuguesa. Neste contexto, este artigo tem como objetivo discutir a TV INES como um acontecimento discursivo. Para isso, tomamos como pressupostos teóricos e metodológicos a Análise de Discurso Materialista, teorizada por Pêcheux, na França, e por Orlandi, no Brasil. As análises desta pesquisa nos permitem dizer que a TV INES atualiza uma memória discursiva sobre os sujeitos surdos, fato que é possível por meio dos movimentos de resistência, os quais produzem deslocamentos nos sentidos produzidos sobre esses sujeitos.
Spectacle, biopower, performativity
Authors: Silva Ana Paula Magalhães da
Published: March 2024

By employing the episode “Nosedive” by Joe Wright as the object of study, this article aims to demonstrate how the concepts of spectacle, biopower and gender performativity form a causal chain, with the society of the spectacle presenting itself as a favorable sociocultural context for the practice of biopower, which, in turn, would reinforce gender-specific technologies of power, thereby stiffening and restricting the possibilities for expression of dissident gender identities. When carried out on the materiality of the body, these control and surveillance strategies become intertwined, forming a cluster of regulatory powers that are difficult to differentiate.

projeto de pesquisa no enfoque dos metagêneros Tutoriais de Youtube e Editais de programas de pós-graduação em linguística
Authors: Cantuário Antonio Artur Silva
Published: March 2024

Objetivamos refletir sobre as orientações relativas ao gênero projeto de pesquisa em tutoriais de youtube e editais e de que modo o projeto de pesquisa é concebido por esses metagêneros em seus aspectos sociais e composicionais. O trabalho situa-se no quadro das análises sociorretóricas de gêneros, em autores como Miller (2009), Bazerman (2006), Swales (1999) e Giltrow (2002) dos quais aproveitamos as concepções de gênero e metagênero para a análise dos dados. A pesquisa é interpretativo-descritiva, qualitativa e usa a adaptação do Modelo de análise temática a partir de um referencial de codificação de Jovchelovitch e Bauer (2017). Tutoriais de youtube e editais indicam que o projeto de pesquisa é intertextualmente situado e posicionado em relação a outros gêneros e se constitui na persuasão e atualidade da temática. Os metagêneros analisados abordam o projeto de pesquisa de modo relativamente diferente.
hashtag como um sistema dinâmico complexo
Authors: Lemes Renan Monezi
Published: March 2024

Este trabalho tem como objetivo refletir sobre a hashtag #corpoperfeito no âmbito da rede social digital Instagram. Utilizamos as proposições teóricas da Teoria dos Sistemas Dinâmicos Complexos (TSDC), orientadas por Holland (1995) e Larsen-Freeman (2008), e elencamos a hashtag em questão como um sistema complexo, assim como a própria língua(gem). Durante o desenvolvimento do artigo, realizamos discussões que demonstraram o funcionamento complexo, dinâmico e adaptativo da hashtag, assim como o conceito de folksonomia, que nos ajudou a compreender o processo de livre indexação. Foi possível verificarmos a existência de padrões nas postagens indexadas através da #corpoperfeito que, de alguma forma, podem trazer prejuízos individuais e sociais para usuários que possuam contato com a mesma. Assim, fizemos o exercício de refletir sobre quais seriam os possíveis impactos causados pela afirmação discursiva de que o corpo necessita de intervenções estéticas para tornar-se perfeito.
Sob a égide da pós-verdade e dos multiletramentos
Authors: Lima Fernanda Fernandes Pimenta de Almeida , Pereira Sara
Published: March 2024

Este artigo tem como objetivo analisar o discurso da pós-verdade em movimentos antivacinação infantil durante o contexto pandêmico do Covid-19. O aporte teórico-metodológico que embasa este trabalho é a Análise do Discurso de orientação francesa, a partir dos preceitos de Foucault (2008, 2014), Paveau (2020), dentre outros. Para estabelecermos, um diálogo com o ensino, integramos ao devido pressuposto a perspectiva bakhtiniana dos gêneros discursivos, em sua relação com os novos e multiletramentos, propostos por Rojo (2004, 2008, 2012, 2015), Soares (2002) e outros autores. Trata-se de uma pesquisa empírica de cunho interpretativo que toma como corpus memes, coletados na rede social Instagram, que, em sua configuração enunciativa, pautada no fundamentalismo político e religioso, faz coro com o movimento antivacinação infantil, subvertendo sua relevância. Como resultado, verificamos a crescente difusão de fake news e o seu impacto sobre a regularização da pós-verdade em reproduções massivas nas redes sociais, o que nos intima a problematizá-las em sala de aula e a refletir sobre o papel da web em estudos de multiletramento.
“Isto não é Tebas, isto é Brasil”
Authors: Macedo Taise Teles Santana
Published: March 2024

Esta proposta discute como o repertório da pandemia da Covid-19 está presente no “Poema para a catástrofe do nosso tempo”, publicado, em 2020, no livro vidas rasteiras, do poeta e artista Alberto Pucheu, um poema-livro dividido em vinte e uma partes cuja narrativa, tecida recentemente sob a égide da crise sanitária mundial, estampa a catástrofe que se abateu sobre o Brasil. A atmosfera trágica se sucede desde 2016, quando uma presidenta foi retirada do seu cargo por meio de um “golpe teatral”, repercutindo, em 2018, quando um Midas às avessas, um partido político e uma ideologia autoritária e de extrema brutalidade assumiram o poder. Ao pensar o Brasil contemporâneo, Pucheu adota uma visão da ascendente queda de um país para refletir sobre os acontecimentos atuais. Diante de um contexto fúnebre, “Poema para a catástrofe do nosso tempo” alavanca imagens de dor, de morte e de perdas que figuram o drama existencial vivenciado por brasileiras e brasileiros tanto em decorrência do coronavírus quanto da inoperância do Estado perante tal tensão sanitária.
Corte e costura da palavra
Authors: Souza Luciéle Bernardi de , Souza Luciane Bernardi de
Published: March 2024

A partir da leitura de Fio de corte (2021), escrito em meio a pandemia de COVID-19, destacamos a autoria feminina como um movimento de criação com, uma práxis não apenas autoral-individual, mas coautoral desdobrada nas vozes líricas. Somando-se aos movimentos sociais e políticos, essencialmente coletivos, a escrita coautoral feminina contemporânea configura um entrelaçamento de vozes que problematizam e tensionam a noção de autoria individual por evidenciar um modo afetivo e conjunto de criar poesia e considerar a complexa relação, sem radicalismos, entre figurações líricas que compõem não um eu, mas um nós lírico. Para tal movimento, seguiremos os fios lançados por Angela Brandão, Ilana Eleá e Lucelena Ferreira e suas figurações.
"Quarto escuro"

Published: March 2024

Este artigo objetiva analisar representações sociais (re)produzidas por professores de língua portuguesa, atuantes na Educação Básica, no contexto de implementação do Ensino Remoto Emergencial. E, em função desse objetivo, especificamente objetivamos: i) identificar  representações sociais (re)produzidas por professores de língua portuguesa, na Educação Básica, no contexto de implementação do Ensino Remoto Emergencial; ii) caracterizar o processo de constituição representacional das representações sociais identificadas. Como fundamentos teóricos, partimos de trabalhos sobre representações sociais e currículo, a exemplo de Moscovici (2007), Jodelet (2001), Pedra (1997), Silva (2001), dentre outros estudiosos. Metodologicamente, este estudo segue o desenho de pesquisa qualitativa, de natureza interpretativista, através da técnica de Grupo de Reflexão para geração de dados. Para esta amostragem, selecionamos os dados de 2 professores de língua portuguesa, que colaboraram com as reflexões sobre a temática currículo. Conforme análise de dados, identificamos que, subjacente às percepções desses colaboradores, há uma representação social (re)produzida sobre um (não)currículo durante o contexto focalizado. O processo de ancoragem e objetivação dessa representação social pode ser viabilizado através da figura do “Quarto Escuro”, evocada por um dos colaboradores, a qual sistematiza o contexto de sobreposição de atividades e ausência de documentos curriculares vivenciado pela classe.
A origem do coronavírus no discurso de sites jornalísticos brasileiros em 2023
Authors: Lacet Vanda Késsia Gomes Galvão , De Farias Washington Silva
Published: March 2024

Neste artigo, buscamos compreender como a origem do vírus da pandemia de Covid-19 foi significada em sites da Grande Mídia (GM), Mídia Conservadora (MC) e Mídia Alternativa (MA) a partir da análise de três reportagens acerca de um relatório confidencial do Departamento de Energia dos EUA sobre o tema, conforme anunciado na imprensa no início de 2023. Nesse cenário, observamos um funcionamento equívoco de formulações, que coloca em dúvida a origem do coronavírus, se natural ou intencional, abrindo margem à produção de efeitos de sentido de culpabilização da China pela pandemia. Dadas suas diferentes orientações ideológicas e discursivas, os sites jornalísticos selecionados produziram gestos de interpretação distintos acerca do referido relatório e da equivocidade de suas formulações. Desse modo, enquanto os sites da GM e MC, cada um a seu modo, buscam estabilizar o efeito de culpabilização da China, apagando a equivocidade do relatório norte-americano, o site de MA tende a desestabilizar esse efeito, expondo o seu caráter político. Recorrendo a pressupostos e conceitos da Análise de Discurso de orientação pecheutiana, visamos, assim, demonstrar como esses funcionamentos são textualizados nas matérias selecionadas mediante inscrição do discurso jornalístico em posições identificadas com a ciência (“vírus natural”) ou o anticomunismo (“vírus vazado”).
Presidente (e) fake news
Authors: Vieira Filho Maurício João
Published: March 2024

Desde março de 2020, quando o marco da pandemia de covid-19 é instituído no mundo pela Organização Mundial da Saúde (OMS), as vidas foram impactadas desigualmente com o espalhamento do coronavírus e das consequências da doença. No Brasil, o vírus se alastra na proporção de desinformações e ataques governamentais. Neste artigo, objetiva-se analisar o discurso de Jair Bolsonaro na reunião de trabalho com o prefeito de Chapecó, João Rodrigues, com vistas a compreender os sentidos atribuídos à pandemia de covid-19 e às ações governamentais. Especificamente, entender as associações entre pandemia de covid-19 e epidemia de HIV/aids realizadas pelo então presidente do Brasil. Os caminhos metodológicos são provenientes da Teoria Semiolinguística e compostos pelas proposições da análise da situação de comunicação (Charaudeau, 2013), das estratégias discursivas (Charaudeau, 2011) e da violência verbal (Charaudeau, 2019). Para além, mobilizamos conceitos de desinformação, fake news, abjeção e estigmatização como lentes teóricas para análise do fenômeno discursivo. Como resultados, nota-se o arregimento da desinformação proferida por Jair Bolsonaro a partir do estatuto de legitimidade, juntamente à mobilização de comparações anacrônicas e errôneas. Em relação à aids, Bolsonaro intensifica a estigmatização com a sugestão da contaminação eivada por sexualidades específicas, ações marcadamente compostas pela abjeção.

THE IMPACT OF LIGHTNING STRIKE ON HYBRID HIGH VOLTAGE OVERHEAD TRANSMISSION LINE – INSULATED GAS LINE
Authors: Boumous Samira , Boumous Zouhir , Djeghader Yacine
Published: March 2024

The electrical network is the set of elements where loads are connected to the generation plants by transmission lines. They can be either overhead or underground cables. A new technology has been introduced to replace these transmission lines with underground cables gas insulated line “GIL”. The latest has many advantages over underground cables and overhead transmission lines, such as low transmission losses, less capacitive load, reliability, personal safety, same operation as overhead lines and negligible electrical aging. GIL can handle much more power than overhead lines due to its large conductive area. GIL is the best for high voltage. In this paper, the simulation of lightning strike effects on a 400 kV hybrid transmission line located in the Wilaya of Setif in northern Algeria is presented in the absence and presence of line arresters and GIL arresters. The results of this paper can provide a rich and valuable theoretical reference for GIL simulation modeling and evaluation of lightning strike impact on hybrid overhead – GIL lines.

The paper is a report of an experimental study to suppress the speckle structure of a coherent optical field. The technique proposed is based on the reduction of the temporal coherence utilizing enriching the output spectrum of Nd:YVO4 laser with intra-cavity second harmonic generation by additional emission lines. Temperature-controlled simultaneous emission of two components at 1.063 mm and 1.066 mm with nearly equal intensities in IR is achived. In the second-harmonic output the emission lines 531.7 nm, 532.3 nm and 532.8 nm were recorded. The influence of the spectrum variation on the formation of a speckle field was checked. Successfully removed intensity zeros and reduced contrast (visibility) from 0.92 to 0.65 in a light scattered by a ground glass diffuser at the angle 35°. A simple consideration of the speckle field dumping mechanism is presented.

Published: March 2024

The paper proposes electromagnetic field equations from the point of view of their adaptation to numerical methods. Maxwell's equations with partial derivatives are used, written concerning field vectors, which most fully reproduce the picture of physical processes in electrical engineering devices. The values of these vectors provide comprehensive information about the field at any spatio-temporal point. The concept of creating mathematical models of electrical devices adequate to physical processes has been developed. Mathematical transformations are carried out according to the rules of differential calculus. Dynamic processes in the elements of electrotechnical devices were analyzed using the apparatus of mathematical modeling. An algorithm for implementing differential equations with partial derivative numerical methods using computer simulation was implemented. The obtained results made it possible to understand the nature of electromagnetic phenomena in nonlinear media. The paper provides calculations of the field parameters in a flat ferromagnetic plate and the groove of the rotor of an electric machine.

Published: March 2024

Significant changes in the stress-strain state cause a change in the soil profile of the massif, which is affected by various physical and chemical factors. In particular, groundwater filtration, mass transfer, heat transfer, dissolution and leaching of soil masses. This can lead to various types of accidents. Therefore, the study of the stress-strain state of the soil massif is an important topic. Nonlinear dependences in the form of polynomials of the modulus of deformation and Lame coefficients on the concentration of salt solutions and their temperature have been received in this research based on experimental research and their statistical processing. This allowed improving the mathematical model of the stress-strain state of the soil taking into account the nonlinear deformation processes occurring in the soil masses under the presence and filtration of saline solutions in non-isothermal conditions.

Published: March 2024

North Sulawesi Province, directly bordering the Pacific Ocean, is located in an area with the highest level of tropical cyclone (TC) activity in the world. As a result, the province is vulnerable to the impacts caused by cyclones, including storm surges. The increase in water levels due to this event has the potential to cause coastal flooding. Previous studies in Manado have identified that sea level rise can be detected through residual water level (RWL), making studying the characteristics of RWL in North Sulawesi important. This research focuses on Manado and Melonguane, allowing for a comparison of characteristics. The data used includes tropical cyclone data from the China Meteorological Administration (CMA) and tidal data from the Geospatial Information Agency. The Unified Tidal Analysis and Prediction (UTide) method is used to identify RWL. The analysis was carried out by using a t-test to compare data at the two locations. The results showed that RWL at those locations had significant differences with Melonguane having the higher value between them. Generally, the increase in RWL in Melonguane occurs shortly after the cyclone period, while the RWL in Manado maximum increases 86 hours after TC's first occurrence.
Keywords: tropical cyclone; residual water level; UTide.

The image of an unmanned vehicle (Drone) is an image/photo obtained from an aerial survey using an unmanned aerial vehicle above the earth's surface at a low altitude and the resolution of the photo obtained is very detailed. The use of drones is a mapping solution for a high level of detail because drone images include high resolution images that can provide more detailed information about the mangrove ecosystem, including the height of mangrove trees and their area. The purpose of this study was to compare the area and height of mangrove trees using a drone with in- situ measurements. The method used is measuring tree height using in- situ data and drone data. Remote sensing survey research using drones can be concluded as a solution to acquire mangrove biophysical parameters. Especially the height and area of mangrove trees, measuring the height of mangroves using drones also needs to be studied more deeply in further research. Based on the results of the analysis carried out at this stage by comparing tree height data in DSM from aerial photographs and tree height data in the field, the difference is in the range of 0.21m to 1.95m, with an average of 0.78 meters. And the area is a fairly significant area with the data obtained.

Ultraviolet is one part of a sunbeam that which have beneficial and detrimental effects on humans. Materials that can protect the skin from exposure to ultraviolet (UV) are called sunscreens or Sun Protecting Agents. The value of the Sun Protection Factor or known as SPF is to show how many times a person's skin protection is doubled so that it is safe under the sun without experiencing dermal problems. Mangroves have long been known to have secondary metabolites including alkaloids, phenolics, steroids, and terpenoids. These compounds have pharmacological and ecological effects. in this study, we obtain extracts from Avicennia marina and Aegiceras floridum leaves followed by testing spectrophotometric to determine their anti-UV activity. The result shows that A.marina and A. floridum extracts have anti-UV activity in the area of 230-270 nm with an SPF value ranging from very high to extreme protection.Moreover both extract do not show dermatological problem on human stability test.
