Aditivos biológicos na compostagem de resíduos para produção de mudas de alface

Trabalho de Conclusão de Curso (Graduação)As atividades agropecuárias e do setor madeireiro contribuem para a geração de resíduos, que se dispostos inadequadamente podem causar prejuízos ao ambiente, no entanto, podem ser aproveitados após o processo de compostagem. O trabalho objetivou avaliar o efeito de microrganismos coletados em solo sob vegetação nativa do bioma cerrado, como aceleradores biológicos do processo de compostagem de resíduos da bovinocultura de leite e da indústria madeireira, visando a produção de substratos com qualidade nutricional para produção de mudas de hortaliças. Os ensaios de compostagem foram realizados em pequenas pilhas, com relação C/N adequada, e foram monitorados os parâmetros avaliados: temperatura; densidade; pH; condutividade elétrica. A compostagem foi realizada utilizando diversas fontes de microrganismos (Embiotic Line®, EM•1®, microrganismos nativos: EM nativo, Saccharomycesÿ, microrganismos presentes naturalmente nos resíduos utilizados na compostagem). A eficiência do material compostado como substrato para produção de mudas de hortaliças, foi realizada em casa de vegetação, utilizando o alface como planta teste. Pode-se observar que quanto à fonte de microrganismos não houve variações significativas, em relação ao processo de compostagem, exceto para o tratamento sem adição de microrganismos onde a temperatura foi inferior ao demais tratamentos. No entanto com relação a fitotoxicidade foi observado diferenças entre os tratamentos nas seguintes variáveis respostas avaliadas: número de folhas; comprimento da parte aérea; comprimento do sistema radicular; massa fresca da parte aérea; massa fresca do sistema radicular e massa seca do sistema radicular, os tratamentos na dosagem de 20% do composto na mistura com Substrato Comercial Bioplant, demonstrou-se superior as demais dosagens em todos os parâmetros analisados. Os compostos EM Nativo e Sem Adição demonstram superioridade em relação aos demais tratamentos em todos os parâmetros de desenvolvimento de planta

A tool for realistic study of nanoparticulate coal rejects

Pollution caused by hazardous and carcinogenic inorganic elements and organic compounds from coal may be more severe when coupled by other sources of pollution. In addition, the modes of occurrence of potential hazardous elements (PHEs) in coal cleaning rejects (CCRs) have been widely investigated using different methods, including statistical methods, which, however, in some cases resulted in misleading interpretations. In order to verify this potential problem and find an effective solution, we selected a data set, which contained comprehensive analyses of CCRs. The secondary products in sulphides-bearing coal mine rejects were studied in demand to determine their geochemical and ecological structures and to assess their position in the reduction of PHEs in the nature. A zone located in south Brazil, which is the major coal power plant in South America, can be given as an example of such a problem. In this work, a novel methodology for the analysis of PHEs in soils and sediments is proposed for this affected coal area. The analytical method combining X-Ray Diffraction (XRD) and advanced electron microscopies shows the importance of nanomineralogy in understanding different circumstances of coal contamination. Several ultrafine-nanoparticles (UNPs) were identified in the sampled soils and river sediments together with the PHEs. A decrease in PHEs was identified in association with UNPs. However, still further investigations are required with regard to the mobility of PHEs in water, atmosphere, soils, and sediments. The site studied around the coal power plant showed the highest sorption capacity possibly due to the high retention ability of components of soil and sediments such as carbon and clay. These observations of the coal-derived nanoparticles confirm their capability of regulating the mobility of hazardous elements, implying the need for restoring complex abandoned coal areas.

Evaluation of the primary care attributes in Rio de Janeiro

Following the legacy of professors Barbara Starfield and Leiyu Shi in Brazil as health policy : the National Health Survey (PNS), led by the Brazilian National Institute of Geography and Statistics (IBGE) and the Primary Care Assessment Tool (PCAT)

We present to the scientific community the pioneering of Brazilian National Institute of Geography and Statistics (IBGE, the Brazilian Census Bureau) in partnership with the Ministry of Health, the largest fieldwork ever conducted in a single country in the world, using the PCAT in a national household sample survey, visiting more than 100,000 households and 40% of the country’s municipalities. In Brazil, PCAT is being consolidated as an instrument to support public policy for the evaluation of primary health care. We believe that it represents a virtuous example of dialogue between scientific community and health management, following the legacy of Professors Barbara Starfield and Leiyu Shi

Measuring the quality of primary care in national health surveys : lessons from Brazil

Background: South Africa started to lead the cross-culturally validation and use of the Primary Care Assessment Tool (PCAT) in Africa, when Professor Bresick filled a gap, as this continent was until then the only one that had never used it in evaluation of primary health care facilities until 2015. Aim: The authors aim to demonstrate that after the consolidation of Bresick’s team to an African version of PCAT, it had been adapted to household survey in Brazil. Methods: In this letter, authors reflect on how Brazil had adapted PCAT to a national random household survey with Brazilian National Institute of Geography and Statistics (IBGE) – the Brazilian Census Bureau. Results: In the the beginning of 2019, Brazilian Ministry of Health brought back the PCAT as the official national primary health care assessment tool. Brazilian National Institute of Geography and Statistics (IBGE) included a new module (set of questions) in its National Health Survey (PNS-2019) and collected more than 100 000 households interviews in about 40% of the country’s municipalities. This module had 25 questions of the Brazilian validated version of the adult reduced PCAT. Conclusion: We believe that IBGE innovation with the Ministry of Health can encourage South Africa to establish a similar partnership with its National Institute of Statistics (Statistics South Africa) for the country to establish a baseline for future planning of primary health care, for decision-making based on scientific evidence

CONSTRANGIMENTOS VIVENCIADOS E SUA REPERCUSSÃO NA SUBJETIVIDADE DOS TRABALHADORES: UM ESTUDO DE CASO COM EX-BANCÁRIOS

Os bancários constituem uma categoria essencial na circulação financeira, os quais se defrontam com um quadro de adoecimento e uma nova significação de sua atividade laboral. Nesse contexto, o presente estudo objetiva verificar os constrangimentos vivenciados e sua repercussão na subjetividade de ex-bancários de uma agência privada localizada no centro de uma cidade no interior de Minas Gerais. Para este, foram conduzidas entrevistas abertas. Espera-se que estabeleça a repercussão na subjetividade dos bancários por meio da situação dos antigos prestadores de serviços desse setor, e também busca-se evidenciar os constrangimentos vividos por estes. Palavras-chaves: bancários; constrangimento; subjetividade
