Abstract The use of computational simulation techniques is an important tool for the coffee harvesting issues, particularly the finite element method. The method is widely used in the structural analysis of agricultural machinery, as well as in the analysis of the stresses and vibrations of coffee branches and peduncles during the harvesting process. The present study aimed to develop three-dimensional finite element models of the plagiotropic branches of the Catuaí Vermelho variety of Arabica coffee in different positions along the orthotropic branches of the plant; considering high-fidelity models. Additionally, by considering the branches’ experimental properties (physical-mechanical), the natural frequencies and vibration modes of the branches were determined by means of computer simulations. First, the geometric properties of the coffee branches were obtained by means of two images taken using a professional camera to obtain the input data of the virtual simulation. For the mechanical properties, it was used a semi-analytical digital scale, to obtain the mass of the specimens. The modulus of elasticity was determined using a universal testing machine. The variability in the simulated natural frequencies could be identified, which was on the order of 30% for the first frequency, regardless of the position of the branch in the plant. These values were lower for the other frequencies. Linear regression fits showed a coefficient of determination, and correlation tests were used to verify the relationship between the values obtained numerically and experimentally, which were validated by using experimental data using the modal analysis techniques.

Resumo A pandemia de COVID-19 teve um imenso impacto nas condições de vida e trabalho de toda a população do país, impactando de modo diferenciado e mais intenso os grupos considerados vulneráveis. O objetivo deste artigo é apresentar um panorama da evolução da pandemia no país segundo os boletins do Observatório Covid-19 Fiocruz, no período entre as declarações de início e de encerramento da Emergência em Saúde Pública de Importância Nacional (ESPIN), fevereiro de 2020 a abril de 2022. Foram utilizados diversos dos indicadores adotados nos 69 boletins publicados para a análise da pandemia, como casos e óbitos por SRAGs e COVID-19, grupos etários, taxas de ocupação de leitos UTI e vacinação, entre outros. A análise da evolução foi organizada entre anos e fases da pandemia, procurando destacar o que caracterizou cada momento. A declaração de encerramento da ESPIN no Brasil coincide com as discussões acerca da transição de pandemia para a endemia, sem que isso represente a eliminação do vírus, das infecções e da doença, colocando-se os desafios de avanços nos processos de vacinação no Brasil e no mundo e da convivência com cenários que poderão exigir a adoção de medidas de proteção temporárias em períodos epidêmicos e de maior risco para grupos vulneráveis.

Abstract The COVID-19 pandemic had a significant impact on the living and working conditions of the entire population of Brazil, having a different and more intense effect on groups considered to be vulnerable. The objective of this article is to present an overview of the evolution of the pandemic in the country according to the bulletins of the Covid-19 Fiocruz Observatory in the period between the declarations of the beginning and end of the Public Health Emergency of National Concern (ESPIN, in Portuguese), February 2020 to April 2022. Several of the indicators adopted in the 69 bulletins published for the analysis of the pandemic were used, such as cases and deaths due to SARIs and COVID-19, age groups, % of occupancy of ICU beds, and vaccination, among others. The evolution analysis was organized between years and phases of the pandemic, seeking to highlight what characterized each moment. The closing statement of ESPIN in Brazil coincides with the discussions on the transition from a pandemic to an endemic scenario, without this representing the elimination of the virus, infections, and disease, posing the challenges of advances in vaccination processes in Brazil and around the world, as well as living with scenarios that may require the adoption of temporary protection measures in epidemic periods and periods of greater risk for vulnerable groups.

Resumo Neste artigo apresentam-se algumas das características do chamado trabalho uberizado, que se encontra em expansão nas plataformas digitais e indicam-se suas principais consequências em relação ao mundo do trabalho. Dada a expansão deste fenômeno, apresentamos duas hipóteses. Na primeira, indicamos que o capitalismo de plataforma vem recuperando formas pretéritas de trabalho, que tiveram vigência no período que podemos denominar como protoforma do capitalismo. Na segunda hipótese, indicamos a possibilidade de estarmos a entrar numa era de desantropomorfização do trabalho, provocada pela eliminação de amplos contingentes de trabalho vivo, substituídos por algoritmos, pela internet das coisas e pela inteligência artificial etc., o que acarreta profundas consequências no mundo do trabalho.

Abstract The purpose of this article is to present some of the characteristics of the so-called uberized labour, which is expanding on digital platforms, and to indicate its main consequences in relation to the world of labour. Given the expansion of this phenomenon on a global scale, we present two hypotheses. In the first, we indicate that platform capitalism has been recovering past forms of labour, which took place during the protoform of capitalism. In the second hypothesis, it is indicated the possibility that we are entering a new era of de-anthropomorphizing of work, since the elimination of large contingents of living labour is exponentially replaced by dead labour that expands in the new digital factory, under the command of the algorithms, internet of things, artificial intelligence etc., further increasing unemployment and bringing profound consequences, both quantitative and qualitative, in the world of labour.

ABSTRACT The piramutaba, Brachyplatystoma vaillantii is a freshwater catfish that is the most abundant fishery resource in the Amazon estuary. Piramutaba trawling is done on industrial fishing scale and is characterized by the presence of many freshwater and marine bycatch species, with and without commercial value. Here we describe the bycatch of the industrial fishery of piramutaba in the Amazon estuary and evaluate the relationship of two important environmental factors, depth and salinity, with the accidental capture of freshwater and marine fishes in the Amazon estuary in the rainy and dry seasons. We identified 21 cartilaginous fish species (19.1% freshwater and 80.9% marine) and 125 bony fish species (25.6% freshwater and 74.4% marine). The bycatch included 64 species without commercial value (43% of all bycatch species), which are always discarded. Freshwater and estuarine fishes exhibited significantly higher abundances in shallower environments, while marine fishes were similarly abundant along the entire depth gradient. On the contrary, the abundance of freshwater fishes significantly decreased, and that of estuarine and marine fishes significantly increased with increasing salinity. Regarding the conservation status of the bycatch species, one is classified as vulnerable (VU), and seven as critically endangered (CR). The information on the bycatch of piramutaba fishery in the Amazon estuary is important to subsidize regional fisheries policies and the management of protected areas.

RESUMO A piramutaba, Brachyplatystoma vaillantii é um bagre de água doce que representa o recurso pesqueiro mais abundante no estuário amazônico. O arrasto da piramutaba é feito em escala industrial, caracterizado pela presença de muitas espécies de água doce e marinha capturadas de forma incidental, com e sem valor comercial. Aqui descrevemos a captura incidental da pesca industrial de piramutaba no estuário amazônico e avaliamos a relação de dois fatores ambientais, profundidade e salinidade, com a captura incidental de espécies de água doce e marinhas nas estações chuvosa e seca. Identificamos 21 espécies de peixes cartilaginosos (19,1% de água doce e 80,9% marinhos) e 125 espécies de peixes ósseos (25,6% de água doce e 74,4% marinhos). A captura incidental incluiu 64 espécies sem valor comercial (43% de todas as espécies capturadas) que sempre são descartadas. Os peixes de água doce e estuarinos exibiram abundâncias significativamente maiores em ambientes mais rasos, enquanto os peixes marinhos foram igualmente abundantes ao longo de todo o gradiente de profundidade. Inversamente, a abundância de peixes de água doce diminuiu significativamente, e a de peixes estuarinos e marinhos aumentou significativamente em salinidades maiores. Em relação ao estado de conservação das espécies capturadas, uma é reconhecida como vulnerável (VU) e sete como criticamente ameaçadas (CR). As informações sobre a captura incidental da pesca da piramutaba no estuário amazônico são fundaentais para subsidiar políticas pesqueiras regionais e gestão de áreas protegidas.

RESUMO: O metil jasmonato (MeJA) é reconhecido como um hormônio vegetal que induz várias alterações bioquímicas relacionadas à qualidade dos frutos, mas é evidente que o efeito do MeJA durante a pós-colheita é muito variável quanto à concentração, espécies de plantas e até mesmo cultivares. O objetivo deste trabalho foi relacionar a aplicação deste regulador em baixa concentração (10 µmol L-1 por 24 h) às mudanças na fisiologia pós-colheita, na incidência de antracnose e na qualidade do mamão ‘Golden’ durante o armazenamento a 24 ± 1 ° C. A partir do sétimo dia de armazenamento, a incidência de antracnose foi reduzida em mais de 50% com o tratamento com MeJA. Incidência da doença também foi reduzida. Embora o MeJA tenha reduzido a acidez dos frutos, os teores de ácido ascórbico e sólidos solúveis não foram alterados durante o armazenamento com o tratamento hormonal. A cor da casca e a firmeza da polpa apresentaram ligeira retenção. A redução na produção de etileno foi acompanhada pela redução da respiração nos frutos tratados. MeJa aumentou a atividade da CAT apenas na casca, enquanto a atividade da SOD não foi induzida por MeJA na casca e na polpa. Embora o aumento da CAT a partir do terceiro dia de armazenamento possa ter contribuído para a redução da peroxidação lipídica na casca, a redução do MDA na polpa não pode ser explicada apenas pela atividade da CAT. Em resumo, a aplicação de MeJA em mamão ‘Golden’ reduziu a incidência e severidade da antracnose, diminuiu a respiração, a produção de etileno e a peroxidação lipídica. Conclui-se que a aplicação de MeJA em baixa concentração (10 µmol L-1) pode contribuir para o controle da antracnose em mamão ´Golden` e retardar o amadurecimento dos frutos.

ABSTRACT: Methyl jasmonate (MeJA) is recognized as a plant hormone that induces several biochemical changes related to improving fruit quality, but it is evident that the effect of MeJA during postharvest is very variable upon concentration, plant species, and even cultivars. The objective of this research was to relate the application of this regulator at low concentration (10 µmol L-1 for 24 h) to changes in postharvest physiology, on the incidence of anthracnose and quality of ‘Golden’ papaya fruit during storage at 24 ± 1°C. From the seventh day of storage, anthracnose incidence was reduced by more than 50% with MeJA treatment. The lesion area after infection was also reduced. Although, MeJA reduced fruit acidity, the ascorbic acid and soluble solids content were not altered during storage with the hormonal treatment. The skin color and pulp firmness showed slight retention. The reduction in ethylene production was accompanied by a reduction of respiration in treated fruits. MeJa increased CAT activity only in the skin whereas SOD activity was not induced by MeJA in both skin and pulp. Although, the increase of CAT from the third day of storage may have contributed to the reduction of lipid peroxidation in the skin, the MDA reduction in the pulp cannot be explained only by CAT activity. In summary, the application of MeJA in ‘Golden’ papaya reduced the incidence and severity of anthracnose, decreased respiration, ethylene production and lipid peroxidation. It is concluded that the application of MeJA at a low concentration (10 µmol L-1) may contribute to anthracnose control in ´Golden`papaya and slows the ripening of fruits.

RESUMO Objetivo: Inquérito nacional de cobertura vacinal aos 12 e 24 meses de idade foi realizado para investigar as quedas nas coberturas a partir de 2016. Métodos: Amostra de 37.836 nascidos vivos das coortes de 2017 e 2018 residentes nas capitais, Distrito Federal (DF) e 12 cidades com mais de 100 mil habitantes, acompanhados nos primeiros 24 meses por registros nas cadernetas de vacinação. Setores censitários foram estratificados segundo condições socioeconômicas, e o mesmo número de crianças foi incluído para cada estrato. Calcularem-se coberturas vacinais de cada vacina e coberturas completas aos 12 e 24 meses, doses aplicadas, válidas e oportunas. Fatores familiares, maternos e da criança associados à cobertura foram pesquisados. Os motivos para não vacinar analisados foram: contraindicações médicas, dificuldades de acesso, problemas no funcionamento do programa e hesitação vacinal. Resultados: Os resultados preliminares mostram que menos de 1% das crianças não foram vacinadas, as coberturas pelo esquema completo são menores que 75% em todas as capitais e no DF, as vacinas com mais de uma dose perdem cobertura progressivamente, há diferenças entre os estratos socioeconômicos, favoráveis aos estratos mais altos em algumas cidades e aos estratos mais baixos em outras. Conclusão: Houve realmente redução da cobertura vacinal em todas as capitais e no DF para as crianças nascidas em 2017 e 2018, denotando piora na execução do Programa Nacional de Imunizações durante os anos de 2017 a 2019. O inquérito realizado não mensurou os impactos da pandemia de COVID-19 que podem ter reduzido ainda mais as coberturas vacinais.

ABSTRACT Objective: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016. Methods: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy. Results: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others. Conclusion: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.

ABSTRACT. This study was performed to investigate the effects of composted tannery sludge (CTS) on the physical properties of tropical sandy soil after seven years of CTS application. CTS was applied to a Fluvisol at five rates (0.0, 2.5, 5.0, 10.0, and 20.0 Mg ha-1) in experimental plots (sized 20 m2) with four replications. Water infiltration into the soil was determined in the field with the concentric-ring infiltrometer method. Bulk density, total porosity, macroporosity, and microporosity were determined in the soil samples. The permanent CTS application altered the physical properties of the soil and led to a decrease in bulk density. The total porosity, microporosity and macroporosity values in the CTS-applied soil ranged from 44.1-51.7, 34.6-39.4, and 9.1-12.8%, respectively. Water-infiltration rates were significantly influenced by CTS. The cumulative infiltrated water in the soil varied from 21.3-34.7 cm. The basic infiltration rate was lower in the unamended soil and increased with an increase in the rate of CTS application. This study confirmed that the physical soil parameters improved after the permanent CTS application. Therefore, this application may be a suitable strategy for improving physical soil properties over time.

ABSTRACT Objectives: Evaluate bone healing time, consolidation, and the complication rate between the minimally invasive plate osteosynthesis and open reduction with plate osteosynthesis in humeral diaphyseal fractures with an intact wedge (AO 12B2). Methods: A retrospective study was carried out between 2016 and 2020. The medical records and radiographs of 18 patients were analyzed, and data were collected regarding the time of consolidation, age, sex, plate size, number of screws, complications such as iatrogenic injury damage to the radial nerve, material failure, and postoperative infection. Results: No statistically significant differences were observed in the variables of age, sex, plate size, and number of screws used or in the RUSHU index (Radiographic Union Score for Humeral fractures). There were no postoperative infections, material failure, or need for reoperation, nor cases of secondary radial nerve injury. After one year, all patients had a consolidation index analyzed by RUSHU >11. Conclusion: both techniques showed similar results, with a high consolidation rate and low rates of complications or iatrogenic damage to the radial nerve. Evidence level III; Retrospective comparative study .

RESUMO Objetivos: Comparar o tempo de consolidação e o índice de complicações entre os métodos de osteossíntese com placa minimamente invasiva e estabilidade absoluta através da placa nas fraturas diafisárias do úmero com cunha intacta (AO 12B2). Métodos: Foi realizado um estudo retrospectivo entre os anos de 2016 e 2020. Foram analisados os prontuários e radiografias de 18 pacientes e coletados dados referentes a: tempo de consolidação, idade, sexo, tamanho da placa, número de parafusos, presença de complicações como lesão iatrogênica do nervo radial, falha do material e infecção pós operatória. Resultados: Não foram observadas diferenças estatisticamente significativas nas variáveis de idade, sexo, tamanho da placa e número de parafusos utilizados, ou no índice de RUSHU (Radiographic Union Score for Humeral fractures). Não houve casos de infecção pós-operatória, falha do material ou necessidade de reoperação, nem casos de lesão secundária do nervo radial. Após 1 ano todos os pacientes tiveram índice de consolidação analisado pelo RUSHU >11. Conclusão: Ambas as técnicas se mostraram com resultados similares, com alta taxa de consolidação e baixas taxas de complicações ou lesão iatrogênica do nervo radial. Nível de evidência III; Estudo retrospectivo comparativo .

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

Abstract Purpose: To present suggestions for behavioral competency development for engineers and Engineering students to work in Industry 4.0. Originality/value: A human-machine collaboration model (with artificial intelligence application) is proposed for training engineering professionals for the workplace. The behavioral skills for Industry 4.0 to be developed in Engineering degree programs and the quality of evidence of their inclusion in such programs of the Federal University of Rio de Janeiro (Universidade Federal do Rio de Janeiro [UFRJ]) are assessed. Design/methodology/approach: The engineer-machine collaboration model draws on Design Thinking (Brown, 2010) and cognitive modeling of engineers based on a model of logical reasoning (Paul & Elder, 2002), integrating the cognitive model with a model of information flows in human-machine interactions (Riley, 1989). A competency model for Industry 4.0 (Prifti et al., 2017), interviews with leaders of Engineering schools of UFRJ, addressing their planning for the implementation of the new National Curriculum Guidelines for Engineering programs (Resolução no. 2, 2019), and application of the GRADE approach (Balshem et al., 2011) supported the identification of evidence of behavioral competencies for Industry 4.0 in the undergraduate programs. Findings: Engineering professionals train their critical analysis and decision-making skills while the machine searches for and processes information and performs simulations. Low quality evidence was found for the training of undergraduates in emotional intelligence, decision-making, and customer relations. No evidence was identified of training in self-management, entrepreneurship, and understanding of the business model.

Resumo Objetivo: Apresentar meios de capacitação comportamental de profissionais e estudantes de engenharia para Indústria 4.0. Originalidade/valor: Este estudo propõe um modelo de colaboração homem-máquina inteligente (aplicação de IA) para capacitação de profissionais de engenharia no local de trabalho. Identifica e qualifica evidências de competências comportamentais para Indústria 4.0 a serem desenvolvidas nos cursos de graduação em Engenharia da UFRJ. Design/metodologia/abordagem: O modelo de colaboração engenheiro-máquina abrange o Design Thinking (Brown, 2010). Trata-se de uma modelagem cognitiva do engenheiro adaptada ao modelo para o raciocínio lógico (Paul & Elder, 2002), com a integração da modelagem cognitiva ajustada ao modelo de fluxo de informações de interação homem-máquina (Riley, 1989). A implementação do modelo de competência para Indústria 4.0 (Prifti et al., 2017), a entrevista com dirigentes da EQ e Poli (UFRJ) sobre o planejamento para implementação das novas DCN de Engenharia (Resolução nº 2, 2019) e a aplicação da abordagem GRADE (Balshem et al., 2011) para qualificação do nível de confiança suportaram a identificação de evidências de competências comportamentais para Indústria 4.0 na graduação. Resultados: Os profissionais de engenharia treinam análise crítica e tomada de decisão, enquanto a máquina busca/processa informação e realiza simulações. Os cursos de graduação da EQ/Poli da UFRJ apresentam baixa evidência quanto à qualificação dos alunos em “inteligência emocional, tomada de decisão e relação com cliente”. Não foram identificadas evidências quanto à capacitação dos estudantes em “autogestão, empreendedorismo e conhecimento de modelo de negócios”.

Abstract: En | Text: En | PDF: En

Abstract The objectives of this study were the biostratigraphic and paleobiogeographic interpretations of the calcareous nannofossil records of the Romualdo Formation (Aptian-Albian) in the south-central portion of the Araripe Basin. The methods used to process the samples were decanting, smear slide, centrifugation, and ultra-thin section confection. The taxonomic and biostratigraphic interpretations were carried out through qualitative and quantitative investigations. A total of 11 genera and 17 species of calcareous nannofossils, namely, Biscutum constans, Biscutum sp., Braarudosphaera africana, Braarudosphaera sp., Calculites sp., Discorhabdus ignotus, Hayesites albiensis, Hayesites sp., Nannoconus bucheri, Nannoconus sp., Retecapsa surirella, Rhagodiscus sp., Thoracosphaera sp., Watznaueria barnesiae, Watznaueria sp., Zeughrabdotus erectus, and Zeughrabdotus noeliae were identified. The integrated analysis of three outcrops suggests two distinct marine phases: the first in the Aptian, recognized in two outcrops, and during the Albian age. The genera Hayesites and Nannoconus suggest a strong Tethyan affinity. Differently, other calcareous nannofossils such as Watznaueria, Thoracosphaera, and Braarudosphaera recorded here are considered more resistant, cosmopolitan, and/or opportunistic species. Biscutum and Zeughrabdotus are sensitive calcareous nannofossils because they are more susceptible to dissolution and cannot be surely used to define this paleobiogeography and biostratigraphic range.
