Published: August 2022

Abstract Objective: to investigate the percentage of professionals with an intention to leave Nursing during the COVID-10 pandemic, as well as the factors associated with this outcome. Method: a cross-sectional study conducted by applying questionnaires to 890 Nursing professionals from the municipality of Pelotas (RS). The outcome was identified by means of self-reports obtained from the question itself. Relative Risks, as well as their Confidence Intervals (95%), were calculated for the independent variables by means of unadjusted and adjusted Poisson regression. Results: the percentage of professionals who stated their intention to leave Nursing was 24.6% (n=219). There was a positive association between the outcome and higher schooling levels, negative evaluation of institutional support, moderate or intense overload, and skin lesions. A negative association was also observed between the outcome and individuals aged 51 years old or more. Conclusion: except for skin lesions, aspects such as lack of support and overload, although they may have been intensified during the pandemic, do not represent a new fact in the health services. In this sense, the associations found in the study reflect the need for cross-sectional actions to promote retention of professionals.

Published: August 2022

Abstract Objective: to analyze the relationship between the concern and fear of COVID-19 with fatalism in the daily work of nurses. Method: analytical cross-sectional study carried out with a total of 449 nurses. Data collection was performed using instruments validated in Peru. In the analysis, the Shapiro-Wilk test and the Spearman correlation coefficient were used, and two multiple regression models were estimated, with variable selection in stages. Results: nurses had a moderate level of fatalism and a low level of fear and concern about COVID-19. The first statistical model, which included sociodemographic variables, explains only 3% of the fatalism variance. However, a second model that includes fear and perception explains 33% of it. Conclusion: Worry, fear and having been diagnosed with COVID-19 were predictors of fatalism. It is suggested the implementation of psycho-emotional interventions in daily work - aimed at Nursing professionals who present high levels of fear or concern - to reduce fatalism and prevent fatal consequences of the pandemic and promote health.

Authors: Albuquerque Fernanda Beatriz Araújo de , Feijó Matheus Oliveira , Smit Jacob Hindrik Antunes , Silva Ricardo Bernardo da , Góes Junior Adenauer Marinho de Oliveira
Published: August 2022

Resumo Aneurismas infecciosos, anteriormente chamados de aneurismas micóticos, são raros; acometem com maior frequência a aorta de pacientes jovens e apresentam maior tendência à rotura do que aneurismas de outras etiologias. O formato sacular é o mais característico, e os agentes etiológicos mais comuns são Staphylococcus sp e Salmonella sp. A literatura fornece informações limitadas e imprecisas sobre a correta nomenclatura, diagnóstico e tratamento da doença. Os autores reuniram três casos cujos procedimentos diagnósticos e terapêuticos foram documentados. Além de relatar essa série de casos, realiza-se uma revisão sobre o tema, a fim de estabelecer estratégias diagnósticas e terapêuticas pertinentes.
Primary infectious aortic aneurysm: a case series and review of the literature
Authors: Albuquerque Fernanda Beatriz Araújo de , Feijó Matheus Oliveira , Smit Jacob Hindrik Antunes , Silva Ricardo Bernardo da , Góes Junior Adenauer Marinho de Oliveira
Published: August 2022

Abstract Infectious aneurysms, formerly known as mycotic aneurysms, are rare, most often involve the aorta in young patients, and have a greater tendency to rupture than aneurysms of other etiologies. The most characteristic shape is saccular and the most common etiologic agents are Staphylococcus sp. and Salmonella sp. There is scant and imprecise information in the literature about correct nomenclature, diagnosis, and treatment. The authors present three cases in which diagnostic and therapeutic procedures were documented. In addition to reporting this case series, the authors also present a review of the subject, outlining pertinent diagnostic and therapeutic strategies.

Published: August 2022

ABSTRACT Background Peripheral artery disease (PAD) has high prevalence and is associated with high risk of cardiovascular events. Surgical or endovascular intervention is necessary in chronic limb-threatening ischemia. Objectives To evaluate the distribution of open and endovascular revascularizations in different regions of Brazil, analyzing the health system costs and mortality related to these procedures. Methods A descriptive, cross-sectional, observational, epidemiological study was carried out to evaluate open and endovascular surgeries performed on the SUS public healthcare system in Brazil, from 2010 to 2020. Data were collected from the SUS Department of Informatics (Datasus). Results Over the period analyzed, 83,218 admissions for open and endovascular surgeries were registered, with a total cost of R$ 333,989,523.17. There were more hospital admissions for percutaneous procedures (56,132) than for conventional surgery (27,086). Most of the procedures (83%) were performed in the country’s Southeast and South regions, while the North region had the lowest number of procedures. Over the period evaluated, there was a decreasing trend for open procedures and an increasing trend for endovascular procedures. The average hospital stay was shorter for endovascular procedures (5.3 days) than for open surgery (10.2 days). The analysis of mortality related to these procedures revealed a higher rate of in-hospital mortality associated with open revascularization than with endovascular (5.24% vs. 1.56%). Conclusions Endovascular techniques constituted the primary approach for revascularization treatment in critical limb-threatening ischemia, with a lower in-hospital mortality rate and shorter hospital stay when compared to open surgeries.
Formulations, Politeness and Facework in Courtroom Interaction: A Study Case
Authors: Burgo Vanessa Hagemeyer
Published: August 2022

ABSTRACT This article aims to analyse how formulations, politeness, and facework are employed by speakers to achieve specific purposes in courtroom interaction. The theoretical framework is based on the concepts of conversation analysis and forensic linguistics, and the corpus consists of the trial of Jodi Ann Arias, which received widespread media attention in the United States. The excerpts under analysis were taken from the final day of the prosecutor’s cross-examination and from a reporter’s transcript of proceedings, both available on the Internet. It is important to highlight that these devices contribute to construct, enhance, threaten, or weaken people’s image involved in this kind of context.
“Um fã teu, quem realmente te admira, jamais faria esse tipo de coisa”: On the existence of appositive free relatives in Brazilian Portuguese
Authors: Medeiros Junior Paulo
Published: August 2022

ABSTRACT Brazilian Portuguese data provide evidence to the claim I make in this paper that there are appositive free relatives, contrary to what Emonds (1979) states, for whom free relatives cannot have appositive semantics or syntax. I argue there are reasons to believe the wh-sentence evidenced in the title of this paper is in fact a free relative that carries appositive content, considering issues such as distribution, matching, the nature of quem and semantic content. The quem-type sentence I put into analysis in the present paper differs from an ordinary (headed) appositive relative clause for it seems to be juxtaposed to the nominal it relates to, being equivalent to it, a condition that leads to the impossibility of a relativization process in Kaynes’s (1994) terms for the derivation of this kind of sentence.
Medical translation: a mapping of Brazilian dissertations and thesis written between 2002 − 2018
Authors: Ferreira Fábio Luiz , Malta Gleiton
Published: August 2022

ABSTRACT This is a bibliometric mapping of studies conducted on medical translation in Brazil. The primary objective is to map master’s, doctoral, and post-doctoral studies from 2002 to 2018, identifying the topics covered, the institutions, and the geographic regions in which they were carried out. The significance of the present study lies in the fact that it indicates regions and institutions, where research on medical translation is conducted, and reveals the regions in which this type of study is scarce. In both cases, the mapping can serve as a reference for researchers who are interested in this area of knowledge. In addition, the mapping can offer input for the implementation of public policies that encourage the development of studies in the area. Data were collected in three digital platforms, namely Domínio Público, Biblioteca Digital de Teses e Dissertações, and Catálogo de Teses e Dissertações da CAPES, by means of typing different keywords in Portuguese, in the search windows available. Of the 14 studies found, 28.6% were doctoral dissertations and 71.4% were master’s theses. All of the studies were conducted in the southeastern and southern regions of Brazil. Cardiology and general biomedicine were the most frequent topics followed by anesthesiology, orthopedics, cardiovascular surgery, arterial hypertension, physiology, geriatrics, gerontology, nutrition, and pharmacy.
Semântica de eventos no domínio nominal: diferenças e semelhanças entre nominalizações e nomes que denotam eventos
Authors: Resende Maurício , Basso Renato
Published: August 2022

RESUMO Nomes que denotam eventos (NDEs), sem contraparte verbal, tais como cirurgia e terremoto, formam uma classe, em geral, deixada de lado na literatura sobre semântica de eventos no domínio nominal, em comparação com as nominalizações. Neste artigo, nosso objetivo é, depois de argumentar linguisticamente que NDEs, de fato, denotam eventos, fornecer uma explicação estrutural para essa característica, baseada nos postulados da Morfologia Distribuída (Halle & Marantz, 1993). Argumentaremos que há duas estruturas distintas que denotam eventos e que os NDEs colocam questões importantes para a semântica de eventos das línguas naturais.
The Intersection between Linguistic Theories and Computational Linguistics over time
Authors: Moreira Alexandra , Oliveira Alcione de Paiva , Possi Maurílio de Araújo
Published: August 2022

ABSTRACT Recent achievements have turned Computational linguistics into a dynamic research area, and an important field of application development that is being explored by leading technology companies. Despite the advances, there is still much room for improvement to allow humans to interact with computational devices, through natural language, in the same way that humans interact with native speakers of the same language. How to make computers understand or create new metaphors, metonymies or other figures of language? Is it possible to develop natural language systems capable of producing lyrics or poetry on the same level as humans? Can we produce systems capable of assigning new meanings to syntactic elements that are immediately perceived as coherent by humans? In this paper, we account for the evolution of computational linguistics, drawing a parallel with the evolution of linguistic theories and speculating about its research opportunities and foreseeable limitations.
A redução da preposição para em relação à palavra precedente
Authors: Huback Ana Paula
Published: August 2022

RESUMO Neste artigo, analisa-se a redução da preposição para a pra no português brasileiro em sequências de (palavra anterior + para ou pra). O Corpus LAEL de língua falada foi adotado para fazer buscas por essas sequências. Considerando-se as 30 sequências mais frequentes de (palavra anterior + para ou pra), análises estatísticas foram realizadas para observar que fatores interferiam nessa redução. Os conceitos de frequência da sequência (Krug 1998, 2003, Bush 2001), frequência relativa (Torres Cacoullos 2006) e frequência de ocorrência (Bybee 2002a, 2002b, 2006) foram utilizados para verificar se a repetição das palavras em alguma dessas formas desempenhava algum papel nas sequências em que para se reduz a pra. Observou-se que a frequência relativa favorece a redução de para a pra, juntamente com classe de palavra, número de sílabas e tonicidade. A partir desse fenômeno, discute-se a possível estocagem de sequências de duas ou mais palavras no léxico mental dos falantes, bem como as consequências disso para processos de variação e mudança linguística.

Published: August 2022

RESUMO Neste trabalho temos por objetivo analisar representações leitoras compartilhadas por estudantes da Escola Agrícola de Jundiaí/Universidade Federal do Rio Grande do Norte, depreendidas a partir de entrevista semiestruturada, de modo a refletir acerca das injunções sociais, culturais, históricas que determinam as formas legítimas de ser e de se apresentar como leitor, que se encontram conservadas, eventualmente questionadas, no que enunciam esses jovens em relação a si, como bons ou não tão bons leitores, e no que enunciam, de modo geral, acerca da leitura. Nesta análise, de base qualitativa, apoiamo-nos em princípios da Análise de discurso, da História Cultural e dos Novos Estudos sobre Letramento. Entre as constatações, vimos que embora sejam leitores nem todos assim se reconhecem. A melhor compreensão do funcionamento desses discursos sobre a leitura, no âmbito do ensino, permite lidar com seu impacto sobre os processos de identificação desses jovens com essa prática, logo, com seu exercício.
Exploring compositional meanings in the picturebook with a two-father family Me, Daddy & Dad (2017)
Authors: Lirola María Martínez
Published: August 2022

ABSTRACT This paper offers a multimodal analysis of the main characteristics of the compositional metafunction in the picturebook with a two-father family Me, Daddy & Dad (2017). The purpose of the analysis is to observe how textual meanings are created. The main tools of the grammar of visual design applied to picturebooks will be used for the analysis, following the model proposed by Painter et al. (2013). The main ideas of the said grammar will be illustrated with a description of images from the picturebook to deconstruct the relationship between the written text and the visual, the types of written and visual themes, the layout, the framing, and the focus. The analysis shows that both fathers take care of the child and do things at home, such as cooking. Consequently, two-father families are promoted and presented in an egalitarian way. However, the analysis shows that there are not open expressions of affection between the characters because, although the two fathers, Daddy and Dad, appear sometimes together, there is hardly any contact between them or between them and the child.

Authors: Farias Júnior Jorge França de
Published: August 2022

RESUMO Esta pesquisa intersecciona o conceito bakhtiniano de circularidade e o conceito de prática discursiva, a partir da perspectiva foucaultiana, a fim de analisar a (co)construção da identidade social dos sujeitos representantes de uma parcela das práticas discursivas da cultura popular pernambucana, mais especificamente, da tribo indígena Xucuru e suas performances do ritual do toré. A metodologia utilizada foi fundamentada a partir de pesquisas de campo e se constituiu pelos seguintes passos: i) observação das performances do ritual do toré da tribo indígena Xucuru, em Pesqueira-PE; ii) elaboração de entrevistas, in loco, com os sujeitos sociais representantes desta comunidade; e iii) captação de material histórico sobre a tribo Xucuru. Após o estudo, é possível afirmar que a identidade social da tribo indígena Xucuru é transformada social e politicamente e se (co)constrói na circularidade dos discursos que, por sua vez, se materializam por meio de referentes linguísticos encontrados ao longo do texto.
The learner corpus path: a worthwhile methodological challenge
Authors: Dutra Deise Prina , Orfanò Bárbara Malveira , Guedes Annallena de Souza , Alves Jessica Ceritello , Fekete João Gabriel
Published: August 2022

ABSTRACT Corpus compilation is a challenging research endeavor that many researchers decide to pursue. Few learner corpora, however, can be easily accessed (e.g.,the International Corpus of Learner English), and none of them carry a variety of text registers written by English learners at different proficiency levels studying in the Brazilian university context. Therefore, the aim of this paper is to present the compilation of a learner corpus, much needed in our research and teaching context, pointing out the advantages of building this type of corpus for the understanding of learners’ needs as well as for pedagogical decision-making based on sound data. Presenting a detailed rationale of the corpus compilation, this article reveals the various decisions made in order to guarantee that fair comparisons can be made. To exemplify the value of building a carefully designed corpus, results of previous studies are compared. Some of the conclusions reached refer to the need for discipline-specific tasks to propel writing proficiency and for authorship skills to be developed in English for Academic Purposes classes to foster academic success.
Análisis empírico de la MDO en el español: tensión armónica entre iconicidad y economía
Authors: Puentes Stephanie A. , Peña Daniel Eduardo Chaves , Jimenez Sergio
Published: August 2022

RESUMEN La marcación diferencial del objeto es un fenómeno gramatical de varias lenguas como el español, en la cual el morfema ‘a’ aparece ante ciertos objetos directos. La teoría actual plantea que este fenómeno está dominado por la tensión entre: la iconicidad (marcación) y la economía (omisión). Para probar esta hipótesis, se utilizó un corpus de 218 millones de tuits de distintas variedades del español. Se encontraron 4.967 casos de marcación, opcionalidad y omisión de la MDO del español de Colombia que se caracterizaron manualmente con 12 rasgos semánticos binarios y que fueron utilizados para estudiar las demás variedades. El análisis estadístico arrojó que el fenómeno está gobernado por dos fuerzas altamente correlacionadas (r=0,92) que se pueden asociar a la iconicidad (13,47%) y la economía (86,53%). Estas fuerzas no son independientes; están controladas por un factor común, el cual se nombra en este estudio como tensión armónica. Se reporta el grado de importancia de los 12 rasgos para proponer una nueva jerarquía que confirma empíricamente otras antes propuestas. Se concluye que la tensión armónica es un modelo plausible con soporte empírico para modelar el porcentaje de la MDO del español.

Published: August 2022

ABSTRACT: Canine transmissible venereal tumor (CTVT) is the oldest known somatic cell lineage. It is a transmissible cancer that propagates naturally in dogs and reportedly contains gene mutations. RASSF1 participates in DNA damage repair, and its downregulation, results in tumor progression. Hence, RASSF1 is a tumor suppressor gene. Its expression was quantified in tumors from seventeen animals and three cell cultures derived from tumors. In general, RASSF1 was underexpressed in 65%, and absent in 35% of tumor samples. Cells from tumor tissue cultures showed decreased expression of RASSF1 in 67% and elevated expression in 33% of samples tested. The tumor tissues showed significantly lower levels of RASSF1 expression compared to cultured cells. Previously we reported that both the tumor microenvironment and the host immune system appear to influence the tumorigenesis and stage of CTVT. This is the first article to demonstrate the expression of RASSF1 in CTVT. Decreased RASSF1 possibly helps tumor progression.
Doramectin intoxication in malnourished 15-month-old cattle
Authors: Machado Mizael , Riet-Correa Franklin , Pedroso Pedro M.O. , Macêdo Juliana T.S.A.
Published: August 2022

ABSTRACT: Macrocyclic lactones are widely used as endectocides in farm animals. Intoxications occur in situations of overdose and/or malnutrition, in young animals, and in genetically sensitive breeds. We describe the intoxication by doramectin in malnourished 15-month-old cattle that received 1.6 times the recommended dose. The animals presented salivation, ataxia, motor incoordination, reluctance to move, and sternal recumbency. Two animals recovered spontaneously; one died and was necropsied. No gross or microscopic changes were observed. This study suggests that doramectin may cause intoxication when administered to malnourished cattle in doses higher than those recommended and that knowing the history is essential to establish a diagnosis.
PIG SLURRY IMPROVES THE PRODUCTIVE PERFORMANCE OF EUCALYPT AND EXCEEDS THE MINERAL FERTILIZATION
Authors: Rosa Anderson , Pereira Natalia , Damaceno Felippe Martins , Zanão Júnior Luiz Antônio
Published: August 2022

ABSTRACT The nutrients contained in the liquid pig slurry (PS) make this residue a potential organic fertilizer for the cultivation of tree species for the production of wood, which can promote the circular economy. This research aimed to evaluate soil chemical parameters, nutritional status, and development of hybrid eucalyptus clone urograndis from PS application for three consecutive years. The treatments evaluated were without fertilization (C); mineral fertilization (NPK) – 300 kg ha-1 year1 of the 02-30-10 formulation; fertigation with PS of 200 m3 ha-1 year1 (FPS200); and fertigation with PS of 400 m3 ha-1 year1 (FPS400). Macronutrients and micronutrients from leaves and soil were evaluated. Tree development was analyzed using stem diameter at breast height (DBH) and total height (Ht). PS treatments resulted in leaves with higher accumulation of K and P and lower accumulation of N, Ca, M, S, Cu, and Fe. The treatments FPS200 and FPS400 presented DBH and Ht equal or superior to the mineral fertilization. Fertilizations with NPK, FPS200, and FPS400 resulted, respectively, in DBH increments 16, 27, and 30% higher than the control. Regarding the chemical attributes of the soil, the use of PS reduced the pH of the soil and increased the levels of P in comparison with the other treatments. The micronutrient values were adequate for fertility and no accumulation of potentially toxic elements at a level considered harmful was observed. The application of PS in eucalyptus hybrid urograndis proved to be an attractive alternative to increase wood production.

Published: August 2022

ABSTRACT Precision silviculture is being developed to manage and improve Calophyllum brasiliense, a tree species associated with wet and swampy soils. This study estimated genetic parameters for growth traits in response to soil resistance as an auxiliary tool for identifying and selecting progenies adapted to water-saturated soils. This was undertaken in a progeny test of C. brasiliense in which 1,200 seedlings grown from seeds collected from a natural population were planted in a randomized complete block design for single-tree plots. Genetic statistical analysis was conducted using the REML/BLUP method. Significant differences (p<0.01) in diameter at breast height were observed among the progenies. The coefficients of genetic variation and heritability at the individual and progeny levels were low for diameter at breast height and height, indicating low genetic control for these traits, while high positive and significant genetic and phenotypic correlations were detected between diameter at breast height and height. Theoretical genetic gains and multivariate statistical analysis indicated three groups of progenies with different degrees of tolerance and adaptability to flooded soils, which could be useful in future breeding programs for this species, although further analysis at advanced ages is still required. The mean heights of tolerant and sensitive progenies were 12 and 58%, respectively, lower than the theoretical values, indicating that constant soil flooding is harmful to this species.
Eucalyptus PLANTATION BENEFITS TO PATCH SIZE AND SHAPE OF FORESTED AREAS IN SOUTHEAST ATLANTIC FOREST

Published: August 2022

ABSTRACT The adoption of mixed plantation systems (exotic and native species) is viable and represents an important alternative in the context of forest and landscape restoration. This study evaluated whether Eucalyptus cultivation is associated with changes in native forest cover and fragment connectivity in the region from 1987 to 2017. The study region (Southeast Atlantic Forest) has been undergoing a forest transition process. Based on land use/land cover maps obtained from satellite images and a pair-wise comparison, it was detected that the dynamics in one land cover were not necessarily associated with the other one. It was verified an increase in Eucalyptus cover since 2007, possibly related to the New Forest Code that allows the use of exotic species in reforestation, provided it does not exceed 50% of the total area. An increase in the native vegetation cover was also observed, highlighting the importance of restoration actions and national regulations. In addition, forest patches were larger and less complex with Eucalyptus presence, indicating that this land cover is potentially beneficial for the landscape connectivity.

Published: August 2022

ABSTRACT The top grafting technique can make early flowering possible and consequently accelerate self-pollination in Eucalyptus breeding, reducing the period of each generation. This study aims to establish a methodology to top graft by applying the growth regulator paclobutrazol in self-pollinated Eucalyptus genotypes to induce early flowering and accelerate inbred line strategies. A total of 448 top grafts of seven genotypes (three Eucalyptus urophylla × Eucalyptus grandis hybrids, one Eucalyptus urophylla, and three Eucalyptus grandis) were performed in two periods of the year: July and October. The top grafting samples were evaluated concerning flower induction and graft development at three-month intervals. A t-test was performed with a 5% significance level for type I error to compare the relevance of paclobutrazol application. A fixed model was also used to analyze the significance of the treatments. The fastest blooming occurred after three months of applying the graft methodology. After two years, the top graftings performed in October presented higher flower bud and fruit production. The top grafting affected the induction of self-pollinated Eucalyptus flowers with enough flower buds produced to follow the next cycle of self-pollination in some genotypes. The effectiveness of self-pollinated top graftings varied with the genotype used as the scion. The paclobutrazol improved the flowering of the top grafting samples. The methodology established in this work allows accelerating self-pollination strategies in the globally important industrial crop Eucalyptus.
Algumas considerações sobre a relação eleições, voto e democracia
Authors: Pinto Surama Conde Sá
Published: August 2022

RESUMO Os temas eleições e democracia estão na ordem do dia. A proposta deste artigo é contribuir para esse debate, a partir do olhar do historiador, refletindo sobre a seguinte questão: quando as eleições e o voto desafiam a democracia? Ao analisarmos os instrumentos políticos que levam à representação, tendo por objetivo a construção de um entendimento sobre os desafios da democracia brasileira, sustentamos que as eleições e o voto desafiam a democracia quando o grau de adesão do eleitor ao regime democrático sofre flutuações e os valores de uma cultura política democrática não são observáveis, e quando a credibilidade das instituições é baixa e os partidos políticos são frágeis.
Quando as eleições e o voto nos desafiam? Reflexões a partir da República Romana Tardia
Authors: Oliveira Julio Cesar Magalhães de
Published: August 2022

RESUMO O objetivo do autor neste artigo é comparar as críticas antigas e modernas às eleições e ao voto partindo do caso específico da República Romana em seu último século. Após uma breve reflexão sobre as origens do vocabulário moderno a respeito das eleições e do voto, o autor discute as razões das críticas de autores como Cícero e seu irmão Quinto à introdução do voto secreto e os esforços que um candidato a uma eleição romana precisava empreender para se eleger. Conclui observando o quanto essa incursão pela política romana do primeiro século a.C. nos ajuda a refletir sobre as limitações das democracias atuais, mas também a questionar a atitude daqueles e daquelas que parecem se contentar mais em condenar os eleitores por não saberem votar do que em lutar pela superação das limitações de nosso sistema à participação popular.
Towards an Alternative 1922: Popular Culture and Rio de Janeiro’s Vernacular Modernisms
Authors: Conde Maite , Shaw Lisa
Published: August 2022

ABSTRACT This article explores cultural innovations taking place in Rio de Janeiro in 1922. The year evidenced numerous changes in the then capital. These have, though, been eclipsed by the dominant focus on avant-garde experimentations by modernist artists in São Paulo. Returning to 1922 and zooming in on Rio, this article explores transformations that altered the space of the city, and its popular cultural landscape. By doing so, the article seeks to widen the landscape of Brazil’s cultural modernity to encompass developments taking place beyond the confines of the modernist movement and the city of São Paulo. It does this by analysing cultural revolutions taking place in 1922 in terms of Rio’s “vernacular modernisms”, to borrow from Miriam Hansen (1999). Specifically it explores changes in urban planning, in popular music and live performance, in the teatro de revista and in popular literature.
Vanguarda e tradição no manifesto da revista Joaquim
Authors: Souza Fabricio
Published: August 2022

RESUMO O artigo explora e discute as análises do “Manifesto para não ser lido”, texto inaugural da revista Joaquim, criada pelo escritor curitibano Dalton Trevisan em 1946. Desde o seu surgimento, a revista é vinculada pela crítica literária à herança da vanguarda modernista que tem como referência a Semana de 1922. Embora também seja vinculado a essa tradição, o conjunto das evidências analisadas sobre o Manifesto possibilita associar Erasmo Pilotto, o responsável por sua elaboração, ao modernismo de tradição simbolista. As divergências entre os membros da revista, em relação à continuidade ou à ruptura com a tradição, oferecem uma perspectiva privilegiada sobre os debates travados acerca do lugar que Curitiba ocupou no cenário modernista brasileiro.
O combate aos matuyús no Patriarcado de Pindorama: o movimento antropofágico na Amazônia
Authors: Galvão Júnior Heraldo Márcio
Published: August 2022

RESUMO O artigo discute a formação de um Clube de Antropofagia no Pará tomando como fontes a Revista de Antropofagia e o jornal O Estado do Pará. Segundo a revista, havia explícita intenção de expansão do movimento antropofágico às demais regiões do país através da criação de clubes regionais e locais autônomos. A Amazônia, considerada pelos modernistas uma espécie de repositório mítico da nação, teria lugar de destaque nestas discussões, e o Pará estava em evidência por ser a origem de artistas, intelectuais e literatos que publicavam tanto em revistas modernistas de Belém quanto na Revista de Antropofagia. As publicações de Eneida de Moraes serão destacadas, pois ela foi a única mulher a transitar entre estas duas realidades, sendo a pessoa que mais discutiu os conceitos antropofágicos no jornal paraense, provavelmente contribuindo na construção do conceito “matriarcado de pindorama”.

Published: August 2022

RESUMO Este artigo tem por propósito refletir sobre as polêmicas relações entre a história do direito do trabalho brasileiro e os usos do passado. Nessa discussão, influenciada pelo contexto de proliferação de discursos de ódio, de negacionismos e de revisionismos, merecem destaque as disputas sobre o passado, em um quadro de crescente interesse público - e político - em torno da história do direito do trabalho. Em jogo estão artefatos simbólicos inerentes ao processo representacional sobre o passado, capazes de impactar na definição dos contornos de agendas normativas em curso para a classe trabalhadora brasileira.

Published: August 2022

RESUMO Nosso objetivo é discutir a mobilização do esporte nas celebrações dos 25 anos da entrada de Salazar no governo (1953). Refletiremos sobre a influência do império para este intuito utilizando-nos como fontes do Boletim Geral do Ultramar, de documentos do Serviço Nacional de Informação, de periódicos que circularam na metrópole e nos territórios do Ultramar e de uma edição do cinejornal Imagens de Portugal. Debruçamo-nos sobre três atividades cujas programações integraram o esporte: as inaugurações de instalações, as competições e o desfile de bandeiras. Concluímos que a presença desta prática é um indicador de sua importância entre as iniciativas salazaristas de produção de discursos de consenso, inclusive no que tange à afirmação do caráter multiterritorial de Portugal, fundamental num momento em que o país sentia os primeiros impactos de pressões internacionais visando à descolonização.

Published: August 2022

Abstract: This paper presents a novel simulation model of the Cyber Process Control System (CPCS) by combining pattern recognition and Cloud Computing (CC). This paper's originality arises from its aim to build a cloud computing platform for autonomous machines, and the exploration of manufacturing data to generate interpretable patterns to be used in process control decision making. The combining of Cloud technology and machine learning brings production to Industry 4.0. The proposed system is tested using data Carbon Fiber Reinforced Polymer (CFRP) routing process. The little information available about the manufacturing process of this type of material and the interaction between the production steps makes the manufacturing process quite difficult. This system generates interpretable rules of controllable operating parameters sent to the controller to keep the machining process within the limits of the specifications. The second step is activated during the drifting conditions in the machining step. Also, the simulation of the machining process is illustrated to generate the relations between input and output variables of the machining process. The findings of the corrective actions are illustrated and the interaction between the two industrial steps is simulated. Finally, current and future CPCS and CC applications in Industry 4.0 are discussed.

ABSTRACT The use of water with different salinity values in the production of vegetable seedlings is an issue of global concern; therefore, selecting tomato cultivars with tolerance to saline water is essential to improve the fruit quality and production. This study aimed to estimate the maximum electrical conductivity of irrigation water that does not harm the production of tomato seedlings and find cultivars with tolerance to the effects of salinity in this phase. In the first experiment, the treatments were arranged in a 3 × 8 factorial scheme (three tomato cultivars and eight values of electrical conductivity of irrigation water). The second experiment was arranged in a 10 × 3 factorial scheme (10 cultivars and three values of electrical conductivity of irrigation water). The 50% reduction in the root dry matter accumulation occurred with the electrical conductivity of irrigation water (ECw) of 2.31 dS m-1. The reduction of more than 50% of the Dickson quality index was observed with an ECw of 6.38 dS m-1. Irrigation with 3.0 dS m-1 impairs the complete emergence and growth of seedlings of all tomato cultivars. Coração de Boi, Dominador, Maestrina, Sheena, and Shanty were the tomato cultivars most tolerant to the irrigation water with 3.0 dS m-1 of ECw. The electrical conductivity of irrigation water higher than 2.31 dS m-1 impairs the root growth of tomato seedlings.

ABSTRACT The semi-arid region of northeastern Brazil is characterized by irregular precipitation and high evapotranspiration, with a common occurrence of water sources with a high concentration of salts. In this context, this study aimed to evaluate the post-harvest fruit quality of grafted guava cv. Paluma under brackish water irrigation and foliar application of salicylic acid. The experiment was conducted under greenhouse conditions in Campina Grande, PB, Brazil, in a randomized block design, adopting a 2 × 4 factorial scheme, corresponding to two levels of electrical conductivity of irrigation water - ECw (0.6 and 3.2 dS m-1) and four concentrations of salicylic acid (0, 1.2, 2.4, and 3.6 mM), with three replicates. Electrical conductivity of 0.6 dS m-1 and salicylic acid concentration of 2.4 mM resulted in higher levels of reducing sugars and soluble solids. Salicylic acid with concentration from 0.6 to 3.6 mM promoted increments in ascorbic acid and at concentrations of 1.9 and 1.5 mM increased the titratable acidity and total soluble sugars, respectively, in the pulp of guava irrigated with water of 3.2 dS m-1. The hydrogen potential of the pulp increased with the application of salicylic acid, ranging from 1.2 to 3.6 mM, regardless of the electrical conductivity of the water.

ABSTRACT Water deficit adversely affects photosynthetic pigment synthesis, photochemical processes, and seedling quality. Exogenous foliar application of salicylic acid (SA) is hypothesized to contribute to photochemical regulation and increase stress tolerance. This study aimed to evaluate the effect of SA in alleviating the effects of water deficit stress on the photosynthetic photochemical activities and quality of Schinus terebinthifolia Raddi. seedlings. The seedlings were subjected to four regimes of water deficit: 0, 4, 8, and 12 days of water restriction (DWR), associated with the application of four concentrations of SA: 0, 50, 100, and 200 mg L-1 (via foliar spray; 10 mL per plant) during 48 days. Growth of S. terebinthifolia seedlings was adversely affected by longer duration of water restriction in absence of SA treatment. However, application of 200 mg L-1 of SA increased photosynthetic pigment levels, photochemical quantum efficiency in photosystem II, and absorbed energy conversion efficiency in seedlings under 12 DWR. The seedling quality was better at 7 and 12 DWR when associated with application of 100 and 200 mg L-1 SA, respectively. The exogenous application of SA contributed positively to pigment concentration and photochemical stability of photosynthesis, and it improved the quality of S. terebinthifolia seedlings subjected to long water restriction periods.

ABSTRACT The study aims to quantify the production costs of maize and sorghum crops under rainfed and irrigated conditions for the generation of ethanol and to evaluate the economic feasibility in different scenarios of marketing price. Two experiments were carried out in the years 2019/2020 and 2020/2021, in an experimental area at the Federal University of Santa Maria, Santa Maria, RS, Brazil. The experiment was in strip plots, in a randomized block design and four replicates. Three irrigation depths, 0, 50 and 100% of the reference evapotranspiration (ETo), as first factor, and two maize cultivars and one grain sorghum cultivar as second factor, using 45 scenarios. The use of full irrigation (100% of ETo) reduces the production costs of the liter of ethanol by 15 and 17.89% and increases ethanol production by 44.18 and 48.25% for maize and grain sorghum crops, respectively. For the market price of R$ 2.00 L-1, the grain sorghum does not show good performance, with negative net present value (NPV) and internal rate of return (IRR). The sale price of R$ 4.00 L-1 and full irrigation is the best economic scenario, with values of NPV of R$ 90,356.93, IRR of 33.83%, benefit/cost ratio (B/C) of 2.28, profitability index (PI) of 3.99 and payback of three years. Maize is economically viable for ethanol production in all scenarios. Full irrigation and market price of R$ 4.00 L-1 represent the best economic scenario, with mean values for NPV of R$ 204,381.68, IRR of 63.35%, B/C of 2.96, PI of 8.67 and payback of 1.58 years, among the cultivars.

ABSTRACT This study aimed to investigate the effect of heat treatments on the total pore volume, surface area of pores, structural characteristics, and functional groups of the materials which derive from the carbonization and pyrolysis of poultry litter. These processes were carried out in porcelain containers containing poultry litter samples, which were then placed in a muffle furnace. The treatments corresponded to three temperatures: samples carbonized at 250 °C and pyrolyzed at 350 and 450 °C. The surface porosity of biochars provides a suitable dimension to improve the water holding capacity, and surface functional groups may help to improve soil fertility. The influence of the temperatures on the pores of the biochar was investigated by using scanning electron microscopy with energy-dispersive x-ray spectroscopy, X-ray diffraction, and Fourier-transform infrared spectroscopy. The characterization of the biochar shows mesoporous structures, as well as increased surface area and pore volume. The chemical composition has potassium at higher concentrations than other metals, while similar surface functional groups were found in the biochar, such as phenolic, aliphatic, conjugated quinones, and OH-phenolic. The thermal treatments applied to poultry litter generated samples with similar physical, chemical, and structural characteristics. Thus, the production of biochar by the farmer and its use as a soil conditioner can contribute to the reduction of agricultural pollution, management, and efficient disposal of residual biomass.

ABSTRACT The state of Rio Grande do Sul, Brazil, has a low maize production when compared to the total demand, particularly under water deficit conditions. This study aimed to estimate the yield gain of maize using irrigation. The FAO Agroecological zone model was used to simulate the yield after previous calibration and evaluation, following an experimental design of randomized blocks, with 40 growing seasons as replicates and 20 sites. Two water management (rainfall and irrigation), three sowing dates (Aug 15, Sept 15, and Oct 15), and three soil textures (sandy, sand-clayey, and clayey) were evaluated. The generic hybrid obtained from calibration based on multiple hybrids with a medium cycle of 150 d was utilized for the simulation. The model evaluation showed an absolute bias of 16% and an overestimated yield of 2%. The mean irrigated and rainfed yields were, respectively, 16,094 and 5,386 kg ha-1. The irrigated yield had statistically superior values for the sowing dates Sep 15 and Oct 15, although it required a greater amount of irrigation. The yield gain reached a maximum value of 56% in the site of São Gabriel, with irrigation amount increasing 14% on the sowing date Oct 15 compared to that of Aug 15. The soil types showed statistical differences for rainfed conditions, and irrigation minimized the differences, while no statistically significant differences were found for the yield. Irrigation showed potential to increase the maize supply, and the response across sites can be considered in the agricultural management plan.
