Em 11 de março de 2020, a Organização Mundial de Saúde declarou que o mundo estava sendo alvo de uma pandemia devido ao novo coronavírus. O objetivo deste trabalho foi analisar o panorama das pesquisas e das políticas públicas focadas na COVID-19, mapeando o desenvolvimento de tecnologias relacionadas ao tema. A pesquisa teve caráter descritivo e exploratório, ao analisar informações de forma abrangente a partir de referências bibliográficas, com enfoque no repositório PubMed. A prospecção tecnológica quantitativa sobre os coronavírus, através de 06 bancos de patentes, vem a complementar essa análise qualitativa. Com a crise global causada pela COVID-19, a produção de conhecimento e plataformas digitais foi extremamente acelerada num curto espaço de tempo. Praticamente todos os países foram afetados pela pandemia, e aqueles que entenderam a gravidade da situação mais rapidamente, e implementaram políticas e tecnologias assertivas puderam mitigar os impactos de curto prazo, principalmente no que diz respeito à preservação de vidas.
Anaerobic digestion is a process that occurs through microorganisms in an anoxic condition and aims to digest organic matter resulting mainly in biogas. This process is common in wastewater treatment WWTs (Waste Water Treatment), which usually occur in bioreactors. In Brazil the most widespread is the UASB (Upflow Anaerobic Sludge Blanket) reactor due to its temperature conditions, which found in the country an ideal parameter. Archeas make up the microbiota responsible for digestion acting in the final stage of methanogenesis. The studies of these organisms are mainly through metagenomics, because laboratory cultivation is difficult. Therefore, the research aimed to study the physical and molecular parameters of the sludge. Four UASB reactors from WWT Center in Petrolina – Pernambuco- Brazil were evaluated. For the DNA extraction process the adapted protocol was applied, the physical analysis of the solids obeyed the determinations of APHA (2005). DNA extraction was achieved with the modified protocol and demonstrated a high concentration of DNA present in the samples, being the 4 most abundant reactor. Physical quantifications of the solids analysis showed that the values found are in compliance with current standards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
