RESUMO
This paper presents an ongoing investigation that analyzes life experiences, processes and systemic impacts of the COVID-19 pandemic and examines the measures and actions to prevent, contain and respond to it. The study is focusing the inequalities on life experiences of the pandemic in populations that live in fourteen vulnerable territories of the Metropolitan Area of São Paulo and the city of Santos (Brazil). The group of researchers is composed of people who live in those territories and students and professors of the São Paulo Federal University.The research design focuses on comprehending the experience of the pandemic in its complexity, through an interdisciplinary production of scientific knowledge that is socially referenced and committed to the participation of the populations studied. The field research in each territory, which counts with the participation of local organizations, is producing a critical reflection on the experience of the pandemic and giving visibility to the centrality of social networks weaved by local actors. This path is allowing us to understand the ways of producing life in territories stressed by inequality and to recognize their challenges. To go through this complex process transversed by the pandemic is the challenge and the richness of this study.
O objetivo geral do artigo é compartilhar a investigação em curso que se propõe a analisar as vivências, os processos e os impactos sistêmicos da pandemia de COVID-19 e das medidas e ações realizadas para a sua prevenção, contenção e enfrentamento. O estudo considera as desigualdades nas vivências da pandemia em populações de diferentes territórios vulneráveis. São 14 territórios da Região Metropolitana de São Paulo e da Baixada Santista. O delineamento da pesquisa busca qualificar o olhar para a vivência da pandemia em sua complexidade, via uma produção interdisciplinar do conhecimento, realizada junto com as populações estudadas. O coletivo de pesquisadores é formado por moradores dos territórios, estudantes e pesquisadores ligados à universidade. Unifica este coletivo o compromisso de produzir conhecimentos científicos socialmente referenciados. O desenvolvimento da pesquisa, em cada território, produzida em conjunto com pesquisadores sociais e organizações coletivas, tem permitido uma reflexão crítica e visibilizado à centralidade das redes construídas pelos atores locais. Esse percurso permite considerar o modo de produzir vida em territórios marcados pela desigualdade e reconhecer seus desafios. Caminhar nesse complexo processo atravessado pela pandemia é o desafio e a riqueza desse estudo.
RESUMO
The aim of this study was to develop a new method for the determination of NO2 levels encountered in clinical settings as well as in environmental studies, using a bi−component atmospheric pressure ionization mass spectrometry(APIMS). Hydrogen (1%) diluted in pure argon was ionized by corona discharge in the first ionization component. Fifty ml of the analyte diluted in 250ml of composite air or carbon dioxide (CO2) was introduced into the second ionization component and analyzed. When composite air was used as the sample carrier gas, NO in the analyte was oxygenated and there was an increase in the NO2 content from that in the original analyte. However, when CO2 was used as the sample carrier gas, the level of NO2 in the analyte could be determined because CO2 did not change the NO2 content from that in the original analyte. A calibration curve with good linearity was obtained using the UG−410 APIMS system, with a regression equation of Y(%)=5.513*10-2 X(ppb) and a detection limit of 0.9ppb. Since APIMS detects NO2 directly within its system, the concentration of NO does not need to be measured. This system may be of great help in the accurate detection and determination of the concentration of low levels of NO2 during inhaled NO therapy
