Nos matizes da memória e da história: uma discussão sobre o folclore fantástico do Recife e seus lugares

Este artigo objetiva discutir, à luz dos textos referenciais de Pierre Nora (1993) e Ulpiano Bezerra de Meneses (1994), as concepções de história e memória, inserindo-as na discussão do folclore citadino. Este patrimônio coletivo é aqui representado pelas lendas do sobrenatural recifense, abordadas pela literatura local. Entre história e memória se estabelece uma clara distinção pelos interesses de tradicionais grupos detentores de poder e as relações sociais de uma coletividade que estão intrinsecamente relacionadas com os fenômenos. Assim, para a leitura de uma realidade social, deve-se contestar os interlocutores responsáveis por sua comunicação. Nesse contexto, o folclore se apresenta como um campo fértil para o debate do poder do vernáculo e do popular de contribuir para a construção de narrativas pautadas pela memória coletiva.Este artículo pretende discutir, a la luz de los textos referenciales de Pierre Nora (1993) y Ulpiano Bezerra de Meneses (1994), las concepciones de la historia y la memoria, insertándolas en la discusión del folclore de la ciudad. Este patrimonio colectivo está representado aquí por las leyendas de lo sobrenatural en Recife, abordadas por la literatura local. Entre la historia y la memoria se establece una clara distinción por los intereses de los grupos tradicionales que detentan el poder y las relaciones sociales de una colectividad que están intrínsecamente relacionadas con los fenómenos. Así, para leer una realidad social, hay que interpelar a los interlocutores responsables de su comunicación. En este contexto, el folclore se presenta como un campo fértil para el debate sobre el poder de lo vernáculo y lo popular para construir narrativas basadas en la memoria colectiva.This article aims to discuss, in the base of the texts of Pierre Nora (1993) and Ulpiano Bezerra de Meneses (1994), the concepts of history and memory, inserting them in the discussion of the city folklore. This collective heritage is here represented by the supernatural tales from Recife, covered by local literature. Between history and memory a clear distinction is established by the interests of traditional groups that hold power and the social relations of a collectivity that are intrinsically related to the phenomena. Thus, to read a social reality, it is necessary to contest the interlocutors responsible for its communication. In this context, folklore presents itself as a fertile field for the debate on the power of the vernacular and the popular to construct narratives based on collective memory

Atributos químicos do solo irrigado com efluente de esgoto tratado e cultivado com pimentão

O uso de efluentes de esgoto tratado (EET) para fins de irrigação se destaca pelo reaproveitamento da água e pelo aporte de nutrientes ao solo, representando os dois principais benefícios ambientais. Assim, o objetivo deste trabalho foi avaliar o efeito da aplicação de EET sobre a quantidade de nutriente adicionado ao solo e alteração nos atributos químicos de um Latossolo Vermelho Amarelo na camada de 0,0 a 0,2 m, sob cultivo de pimentão, híbrido Canário F1, irrigado por gotejamento superficial. O experimento foi desenvolvido em condições de campo no período de setembro de 2015 a janeiro de 2016. O delineamento estatístico foi em blocos casualizados, com quatro repetições, com os seguintes tratamentos: água de córrego, EET, água de córrego com adubação de base, EET com adubação de base, EET com adubação de cobertura e EET com adubação de cobertura e de base, com quatro repetições. A irrigação com EET no cultivo de pimentão aumentou os teores de potássio, mas não afetou os teores de fósforo, matéria orgânica e o pH do solo ao final do ciclo de cultivo. Foram adicionados ao solo, por meio de irrigação com EET, 10 kg ha-1 de nitrogênio total,10 kg ha-1 de potássio total e 0,5 kg ha-1 de fosfato total. De maneira geral, a aplicação de EET promoveu maior produtividade de pimentão do que o uso de água de córrego, mesmo sob complementação de adubação mineral.The use of treated sewage effluents (TSE) for irrigation purposes is a viable alternative for wastewater reuse and nutrient supply to the soil, which represent the two main environmental benefits. This work therefore evaluated the effect of the application of TSE on the quantity of nutrients added to the soil and changes in the chemical attributes of a Red-Yellow Latosol in the layer from 0.0 to 0.2 m cultivated with the bell pepper F1 Canary hybrid and surface drip irrigated. The experiment was carried out under field conditions from September 2015 to January 2016 in a randomized block statistical design with four replications, including the following treatments: river water, TSE, river water with base fertilization, TSE with base fertilization, TSE with cover fertilization, and TSE with cover and base fertilization. Irrigation of the bell pepper cultivation with TSE increased the level of potassium but did not affect the levels of phosphorus, organic matter and pH of the soil at the end of the growing cycle. The following amounts of nutrients were added to the soil by irrigation with TSE: 10 kg ha-1 of total nitrogen, 10 kg ha-1 of total potassium and 0.5 kg ha-1 of total phosphate. In general, TSE induced greater productivity of the peppers than those irrigated with river water, even when including mineral fertilization

Influence of physical exercise practice against SARS-CoV-2 (COVID-19) infection: narrative review

As a protective measure against the Covid-19 virus, the world health organization strongly recommended social isolation. Because of a lower offer of physical exercise, there was an increase in the number of physical inactivity, poor diet, and psychological disorders. In this sense, this literature review aims to address how the practice of physical exercise is important to protect the metabolic and psychological health of the population. During forced isolation, it was possible to observe an increase in sedentary lifestyle and poor diet. As an outcome, possible damage to the population's mental health was also identified. In contrast, it was observed that individuals who practiced physical exercise, managed to mitigate both metabolic and psychological damage. Ahead, it was also possible to observe that this practice significantly contributed to the individuals' immune system, which can collaborate with the organism in the fight against possible contamination. Given this, the objective of this review was to identify possible implications of physical exercise on psychological and immunological aspects in coping with Covid-19. Important physiological effects of exercise were found, such as elevation of the brain-derived neurotrophic factor (BDNF), which has beneficial effects in controlling depression and cognitive performance; the control of obesity through specific training methodologies can collaborate to control pro-inflammatory cytokines and increase mitochondrial function and immune system. In addition, there are up to 205 symptoms after infection by SARS-CoV2 and physical exercise can be a great ally for recovery. Therefore, it is believed that regular exercise has positive effects before, over, and post-pandemic

This article aims at the heritage values’ identification of the Parque dos Manguezais (Recife’s Conservation Unit) which represents its natural significance and consists of the initial stages in the heritage conservation’s process, according to the Australian Natural Heritage Charter (IUCN, 2002). For the values identification, distinct actor categories were interviewed surrounding residents, specialists, public agents), whose testimonies were analyzed based on content analysis method. As result, there were established heritage dimensions related to the Conservation Units’ ecological and cultural aspects, as well as the interrelations that actors maintain with the ecosystem that signal the objective actions of conservation of the Parque dos Manguezais’ were considered.O presente artigo tem como objetivo a identificação dos valores patrimoniais do Parque dos Manguezais (Unidade de Conservação do Recife) que representam a significância natural do bem e que consiste na etapa inicial do processo de conservação patrimonial, de acordo com a Australian Natural Heritage Charter (IUCN, 2002). Para identificação dos valores, foram entrevistadas distintas categorias de atores (moradores do entorno, especialistas e agentes públicos), cujos depoimentos foram analisados com base no método Análise de Conteúdo. Como resultado, foram estabelecidas as dimensões patrimoniais relacionadas aos aspectos ecológicos e culturais da Unidade de Conservação, assim como foram levadas em consideração as inter-relações que tais atores mantêm com o ecossistema e que sinalizam as ações objetivas de conservação do Parque dos Manguezais

Inability of 7,8 – Dihydroxy-4- Methylcoumarin antioxidant activity, to prolong longevity and to protect against stress in Caenorhabditis Elegans worms

Despite an increase in life expectancy, it is known that this factor is not necessarily accompanied by a better quality of life, which reflects in longevity. Aspects related to metabolic stress to which cells are subjected can modulate this process, which can lead to various pathologies. Coumarins are secondary metabolites found in several plants, such as guaco, and are part of the polyphenol family capable of producing up to 1300 derivatives, with potential effects against metabolic stress, in addition to being used in the cosmetics industry with the objective of improving fragrance of products. Therefore, it seems necessary to seek to elucidate molecular mechanisms that can regulate this aging process, which can be associated with the gradual loss of physiological functions of cells and tissues, increasing the number of cells in senescence that may be related to increased oxidative stress. PURPOSE: the aim of this study was to identify the influence of the use of the coumarin synthetic compound 7,8-Dihydroxy-4-methylcoumarin (DHMC) on longevity and resistance to different types of stress in vivo. METHODS: free radical scavenging (DPPH) analyzes were performed for the compound, longevity, and stress tests (H2O2, NaCl, Heat) for C. elegans worms. RESULTS: in the first analysis, the compound showed 92% of antioxidant activity already in small concentrations (25ug/ml) through DPPH analysis. In the following tests DHMC did not show antibacterial responses against Escherichia coli, and Caenorhabditis elegans worms did not show stress reduction or significant improvement in longevity with the use of the compound. CONCLUSION: therefore, the DHMC compound expresses a high antioxidant activity and presents several study potentials. However, it has no biological effects in protecting against stress or contributing to longevity in C. elegans worm

Effects of culture filtrates of endophytic fungi obtained from Piper aduncum L. on the growth of mycobacterium tuberculosis

Substances that inhibit the growth of Mycobacterium tuberculosis could potentially be used as antibiotics. These substances could also be added to test culture media to improve the speed of tuberculosis diagnosis. The aim of this work was to investigate the influence of culture filtrates of endophytic fungi isolated from P. aduncum L. on the growth of M. tuberculosis. To achieve this objective, the following methodology was used: a) endophytic fungi were isolated from the leaves and stems of P. aduncum L.; b) the isolated fungi were submitted to submerged bioprocessing; c) culture filtrates from the bioprocess were assayed to evaluate their effect on the growth of M. tuberculosis. We isolated 315 fungal types, which represented 85 morphologies, from different parts of P. aduncum L. The bioassays were performed on 82 culture filtrates and 6 plant extracts and resulted in the detection of 1 culture filtrate that stimulated the growth of M. tuberculosis and 15 that inhibited microbial growth. None of the phytochemical extracts had an effect on the growth of M. tuberculosis. In conclusion, we observed that the endophytic fungi isolated from P. aduncum L. (Piperaceae) produced extracellular metabolites (present in the culture filtrate) that affect the growth of M. tuberculosis. These compounds have the potential to be used as antimicrobials or in the diagnosis of tuberculosis. © 2011 by Pontificia Universidad Católica de Valparaíso, Chile
