The aim of this study was to identify the relation between the evapotranspirometer demand and the supply of water from local rainfall, evaluating the possibility of using water excess for irrigation of Green Roofs in the State of Mato Grosso, in Brazil. The study was done using a series of historical data provided by the National Institute of Meteorology (INMET - Instituto Nacional de Meteorologia) which has official climatological stations in 12 cities and regions of the State. The evapotranspiration values were obtained by the Penman-Monteith method and by the Climatic Water Balance (CWB) by the Thornthwaite and Mather method using Available Water Capacity (AWC) of 12mm. With the CWB the excess and deficit were calculated, which were used for the estimative of the volume and area of a reservoir as a function of a collector area of a roof of 100m² and the volume of supplementary water for irrigation. With the obtained results, it was found that in most investigated regions of the State the use of green roofs is not compromised by the water deficiency. On the other hand, the use of a reservoir to accumulate the rain water excess may be impractical, because it requires a considerable area for installation and also because of the high cost of the land.
ResumoConsiderando a necessidade da inserção das tecnologias digitais direcionadas para a aprendizagem, os Objetos Digitais de Aprendizagem apresentam grandes possibilidades para contribuir com a produção do conhecimento matemático. A partir disso, o presente trabalho tem como objetivo verificar os tipos de Objetos Digitais de Aprendizagem no Ensino de Matemática, que constam em Artigos e Dissertações Brasileiras publicadas entre os anos de 2010 a 2020, coletados em cinco bancos de dados on-line. Além disso, apresenta o tratamento e análise qualitativa dos dados com o software MAXQDA, o qual possui como principal finalidade, facilitar e acelerar a análise qualitativa de dados através de codificações e categorização. Nesse sentido, esta pesquisa utiliza a revisão sistemática de literatura como metodologia de pesquisa. Por fim, após a análise, foram categorizados os Objetos Digitais de Aprendizagem em oito categorias, e se verificou que a categoria softwares teve destaque como o principal tipo de Objetos Digitais de Aprendizagem, em maior parte, esses estavam ligados ao estudo do conteúdo de geometria. Palavras-chave: Objetos Digitais de Aprendizagem. Matemática. Análise de Dados Qualitativos. AbstractConsidering the need for the insertion of digital technologies aimed at learning, Digital Learning Objects present great possibilities to contribute to the production of mathematical knowledge. Therefore, the present work aims to verify the types of Digital Learning Objects in Mathematics Teaching which are listed in Brazilian Articles and Dissertations published between the years 2010 to 2020, collected in five online databases . In addition, it presents the data treatment and qualitative analysis with the MAXQDA software, which has as its main purpose to facilitate and accelerate the data qualitative analysis through encodings and categorization. Thus, this research uses systematic literature review as a research methodology,. Finally, after the analysis, the Digital Learning Objects was divided into eight categories, and it was found that the software category stood out as the main type of Digital Learning Objects, mostly, they were linked to the study of geometry content. Keywods: Digital Learning Objects. Math. Qualitative Data Analysis.
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.
