Evaluation of Physicochemical and Microbiological Parameters of Wastewater Submitted to Constructed Wetland Treatment System

The use of natural systems such as wetlands constructed in the treatment of wastewater has become increasingly important due the ability of these systems to remove large amounts of macronutrients and microorganisms and to promote the degradation of organic matter. Given this background, the main objective of this study was to evaluate the efficiency of an experimental constructed wetland horizontal flow system subsurface cultivated with Zantedeschia aethiopica filled with sand and gravel substrates. The parameters were evaluated by the characterization of physicochemical and microbiological indicators of wastewater from the septic tank of the State University of Goiás in Anápolis city, Goiás, Brazil. The reductions of macronutrients ranged from 57.9 to 94.7%, and 87.0 to 91.0% for organic matter. In addition, a significant reduction in coliform levels in wastewater was observed after wetland treatment. It was concluded that the constructed wetland system could be proposed to treat wastewater from septic tanks at both secondary and tertiary levels, due to its high percentage efficiency in the removal of organic matter and macronutrients. The results obtained demonstrated the applicability of the studied system to be used as a versatile, sustainable, and economical treatment of effluents complementary to the septic tank treatment system.O uso de sistemas naturais como wetlands construídos no tratamento de águas residuais, tem se tornado cada vez mais importante devido à capacidade desses sistemas em remover grandes quantidades de macronutrientes e micro-organismos, além de promover a degradação da matéria orgânica. Diante desse cenário, o objetivo principal deste trabalho foi avaliar a eficiência de um sistema experimental de fluxo horizontal de wetland construído em subsuperfície cultivado com Zantedeschia aethiopica preenchido com substratos de areia e cascalho. Os parâmetros foram avaliados por meio da caracterização de indicadores físico-químicos e microbiológicos do efluente da fossa séptica da Universidade Estadual de Goiás na cidade de Anápolis, Goiás, Brasil. A redução dos macronutrientes variou de 57,9 a 94,7% e de 87,0 a 91,0% para a matéria orgânica. Além disso, foram observadas reduções significativas de coliformes após o tratamento de águas residuais em áreas úmidas. Concluiu-se que o sistema wetland construído pode ser proposto para o tratamento de efluentes de fossas sépticas em nível secundário e terciário, devido ao seu alto percentual de eficiência na remoção de matéria orgânica e macronutrientes. Os resultados obtidos demonstraram a aplicabilidade do sistema estudado em ser utilizado como um tratamento versátil, sustentável e econômico de efluentes complementar ao sistema de tratamento de fossa séptica

A Boa Companhia: sozinhos nós andamos rápido, em grupo, vamos mais longe.

Este artigo apresenta uma reflexão sobre a história e os meios de composição da Boa Companhia (fundada em Campinas, 1992). Para tanto, o texto se utiliza de estratégias claras de análise deste material que vem da pesquisadora e não do grupo: o conceito de Dialogia (BAKHTIN) e de Palavra-corpo (NUNES). Assim, será este passeio pautado não só pelo ato de contar o que vemos, mas também como vemos e como é ter seu trabalho visto

MARINE QUALITY ASSESSEMENT OF AMAZON MANGROVES USING BENTHIC AND DIVERSITY INDICES BASED ON POLYCHAETE FAUNA

The aim of this study was to evaluate the impact of environmental disturbances in two mangroves in the Gulf of Maranhão, Brazil, based on the composition of polychaete communities. We collected samples from two sites: Buenos Aires stream, which is located near the Port of Itaqui, and Quebra Pote. We collected samples from three different zones at each site to evaluate possible gradients of environmental disturbance. We used biotic indices (AMBI, M-AMBI, BENTIX) and diversity indices to assess the level of disturbance. We found 731 specimens of polychaetes belonging to 11 families. The highest polychaete abundance occurred when there was a period of lower salinity in March 2014. The species Paraonis sp. and Syllis sp. were the most abundant. Further analysis of these indices revealed there were likely different sources of environmental disturbance between the two study sites. We suggest that at the Buenos Aires stream, the pollution probably comes from the sea towards the continent, whereas at the Quebra Pote, pollution is likely to originate from the continent and flow into the sea. We strongly encourage that thorough monitoring of mangrove forests is imperative for the survival and health of benthic communities

Meanings assigned by primary care professionals to male prenatal care: a qualitative study

Background: Considering recent strategies used in prenatal care, the involvement of fathers has been considered an important factor in ensuring that pregnancy and delivery are successful. Objective: The aim of this study is to identify the meanings assigned by primary health care professionals to male prenatal care. Methods: This is a descriptive study with a qualitative approach. A total of 19 interviews were conducted with primary health care professionals registered in the City Health Department of Teresina, Piauí, Brazil. Data were collected through semi-structured interviews and analyzed according to the Collective Subject Discourse methodology. Results: Three themes emerged from the reports’ analysis: The importance of the role of fathers in the gestational process, attitudes of men toward male prenatal care and formal education and training in primary health care. Health practitioners understand the importance of male prenatal care but reported they lack proper training to provide effective care. Conclusion: The expansion of continuing education strategies focusing on male prenatal care and directed to primary health care professionals is recommended to promote greater adherence on the part of fathers in prenatal care, with the purpose of strengthening bonds and improving the care provided to the entire family. The humanized care can facilitate the approach of the paternal figure during male prenatal care.info:eu-repo/semantics/publishedVersio

Aplicativos para promoção da saúde mental no contexto da pandemia de Covid-19: uma revisão integrativa

The objective was to identify scientific evidence on the development of mobile apps built to promote mental health in the context of the COVID-19 pandemic. It is an integrative review of the scientific literature carried out in the Medline, Web of Science and Lilacs databases, and in the Cochrane library with the following guiding question: what is the scientific evidence on the development of mobile apps built to promote mental health in the context of the COVID-19 pandemic? A total of 194 studies were found, of which 181 were excluded for not addressing the theme and nine for not answering the guiding question, in this search scenario, four articles were identified. The findings demonstrate the existence of apps in the mental health area addressing the themes of depression, anxiety, psychological stress, burnout syndrome, suicidal ideation and psychological suffering, as well as the absence of scientific publications on the apps already available on digital platforms.O objetivo foi identificar evidências científicas sobre o desenvolvimento de aplicativos móveis construídos para promoção da saúde mental no contexto da pandemia de COVID-19. Trata-se de uma revisão integrativa da literatura científica realizada nas bases de dados Medline, Web of Science e Lilacs, e na biblioteca Cochrane com a seguinte questão norteadora: quais as evidências científicas sobre o desenvolvimento de aplicativos móveis construídos para promoção da saúde mental no contexto da pandemia de COVID-19?
