Biossecagem: uma alternativa para os resíduos sólidos urbanos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia CivilUTFPR, 2020-03-13)
The generation of municipal solid waste (MSW) is constantly growing, a consequence of a series of factors, such as population growth and society’s consumption habits. As a result of high generation and more restrictive ...
Use of a lignocellulosic residue as solid fuel: The effect of ash content in the energy potential
(Elsevier B.V., 2018-06-01)
Bark is a residue that can be used as fuel by the industry. One of the problems of its use is the impurity that it may contain. This study aimed to characterize physically and thermo-chemically the eucalyptus bark used as ...
A nonlinear mixed-effects modeling approach for ecological data: Using temporal dynamics of vegetation moisture as an example
(Wiley, 2019-08-15)
Increasingly, often ecologist collects data with nonlinear trends, heterogeneous variances, temporal correlation, and hierarchical structure. Nonlinear mixed-effects models offer a flexible approach to such data, but the ...
Estudo da coqueima de carvão mineral brasileiro e biomassa utilizando leito fluidizado borbulhante em escala de bancada
(Universidade do Vale do Rio dos Sinos, 2018-03-21)
Based on bubbling fluidized bed technology, a bench scale combustor was used to conduct research works in co-firing of coal and biomass (wood shavings) blends. South Brazilian subbituminous coal, beneficiated to achieve ...

Effects of biological legacies and herbivory on fuels and flammability traits: A long-term experimental study of alternative stable states
(Wiley Blackwell Publishing, Inc, 2017-09)
Ecological memory, often determined by the extent and type of retained biological legacies present following disturbance, may produce persistent landscape patterns. However, after fire, the persistence or switch to an ...
The role of drought conditions on the recent increase in wildfire occurrence in the high Andean regions of Peru
(CSIRO Publishing, 2023-01-24)
Wildfire occurrence has increased sharply in the last two decades in the Peruvian Andes. There is, however, little research on wildfires and their impacts. This study explores the conditions conducive to wildfire during ...
Avaliação de perda de energia em função do teor de umidade em cavacos de Pinus sp
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilEngenharia FlorestalUTFPR, 2015-06-23)
After years of exploration, the timber shortage started to become worrying in Brazil, which led to a series of tax incentives giving rise to the first commercial plantations, mostly species of Pinnus and Eucalyptus. ...
Prediction of flammability limits for ethanol-air blends by the Kriging regression model and response surfaces
(2017-01-01)
Flammability limits must be identified in order to assess and control handling risks of particular processes according to combustion product composition and environmental conditions. Thereby, the present paper aims to ...
