Twenty-first-century demographic and social inequalities of heat-related deaths...
Santos, Djacinto Monteiro dos; Libonati, Renata; Garcia, Beatriz N.; Geirinhas, João L.; Salvi, Barbara Bresani; Silva, Eliane Lima ePopulation exposure to heat waves (HWs) is increasing worldwide due to climate change, significantly affecting society, including public health. Despite its significant vulnerabilities and limited adaptation resources to rising temperatures, South America, particularly Brazil, lacks research on the health impacts of temperature extremes, especially on the role played by socioeconomic factors in the risk of heat...
Global-scale statistical modelling of the radiative power released by vegetatio...
DaCamara, Carlos C.; Libonati, Renata; Nunes, Sílvia A.; Bermudez, P. de Zea; Pereira, José M.C.We present a statistical model with 8 parameters that combines three components, namely a truncated lognormal distribution central body with a lower and an upper tail, both consisting of Generalized Pareto (GP) distributions. We fit the model to a dataset of more than 85 million records of the logarithm of fire radiative power (FRP) at the global scale, as derived from satellite observations covering a 19-year ...
Estimativa dos períodos de retorno da velocidade e rajada do vento e altura sig...
Mazzaro Dias, Emille; Pinto de Almeida Palmeira, Ana Cristina; Libonati, RenataThe Southwest Atlantic region hosts the two main oil basins in Brazil: Campos Basin and Santos Basin. In these regions, the study of extreme events and the estimation of return level are crucial issues to ensure the structural safety of ships, offshore platforms and coastal constructions. The knowledge of the wave and wind regime of a region is indispensable because from this analysis it is possible to estimate...
Erythrina velutina Willd. alkaloids: Piecing biosynthesis together from transcr...
Chacon, Daisy Sotero; Torres, Taffarel Melo; da Silva, Ivanice Bezerra; de Araújo, Thiago Ferreira; Roque, Alan de AraújoMade available in DSpace on 2021-06-25T11:12:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Introduction: Natural products of pharmaceutical interest often do not reach the drug market due to the associated low yields and difficult extraction. Knowledge of biosynthetic pathways is a key element in the development of biotechnological strategies for plant specialized metabolite production. The s...
Heat-related mortality at the beginning of the twenty-first century in Rio de J...
Geirinhas, João L.; Russo, Ana; Libonati, Renata; Trigo, Ricardo M.; Castro, Lucas C.O.; Peres, Leonardo F.; Magalhães, Mônica de Avelar F.M.Temperature record-breaking events, such as the observed more intense, longer-lasting, and more frequent heat waves, pose a new global challenge to health sectors worldwide. These threats are of particular interest in low-income regions with limited investments in public health and a growing urban population, such as Brazil. Here, we apply a comprehensive interdisciplinary climate-health approach, including met...
Caracterização climática de ondas de calor no Brazil
Geirinhas, João Lucas; Trigo, Ricardo Machado; Libonati, Renata; Peres, Leonardo de FariaDe acordo com a última geração de modelos climáticos, a probabilidade de ocorrência de grandes ondas de calor nas próximas décadas tende a subir de forma significativa. Atualmente existem inúmeros estudos relativos a esta problemática no Hemisfério Norte, particularmente para a Europa e para a América do Norte, devido aos seus impactos significativos em áreas como a saúde, economia e agricultura. Em relação ao ...
Burned area mapping in the brazilian savanna using a one-class support vector m...
Pereira, Allan A.; Cardoso Pereira, José Miguel; Libonati, Renata; Oom, Duarte; Setzer, Alberto W.; Morelli, Fabiano; Machado-Silva, FaustoWe used the Visible Infrared Imaging Radiometer Suite (VIIRS) active fire data (375 m spatial resolution) to automatically extract multispectral samples and train a One-Class Support Vector Machine for burned area mapping, and applied the resulting classification algorithm to 300-m spatial resolution imagery from the Project for On-Board Autonomy-Vegetation (PROBA-V). The active fire data were screened to preve...
The North Atlantic oscillation and European vegetation dynamics
Gouveia, Célia; Trigo, Ricardo M.; Camara, Carlos C.; Libonati, Renata; Pereira, J.M.C.The relationship between vegetation greenness and the North Atlantic Oscillation (NAO) is assessed over Europe. The study covers the 21-year period from 1982 to 2002 and is based on monthly composites of the Normalised Difference Vegetation Index (NDVI) and Brightness Temperature from the Global Inventory Monitoring and Modelling System (GIMMS) as well as on monthly precipitation from the Global Precipitation C...
