Abstract: The characterization of gaseous mixtures is an increasingly important issue in the fields of fuel analysis and aerosol research. Analyses by refractometry combined with refractive mixing rules are also powerful tools in this area. In this work a setup comprised by a six-laser interferometer and a vacuum system was Leia mais…

Abstract: This paper presents a thermodynamic and kinetic model for simulating calcium carbonate scaling in a tubularreactor under varying saline composition, temperature, and flow rate. Simulation results are compared withexperimental data obtained from a tubular reactor developed by the IPT and Petrobras. A mathematicalmodel based on thermodynamics and crystallization kinetics Leia mais…
Abstract: When oil spills occur, a fraction of the oil may get trapped in soil pores or can migrate through unsaturated and saturated zones. Dense non-aqueous phase liquids (DNAPL), such as creosote, move through aquifers until complete depletion or encountering an impermeable layer. The optical image profiler (OIP) is a Leia mais…
Resumo: Diante do crescimento exponencial na frequência e intensidade de extremos climáticos em todos os continentes, crescimento este decorrente do aquecimento global resultante do acúmulo de gases de efeito estufa na atmosfera, faz-se mister desenvolver a capacidade de previsão de tais extremos climáticos com maior antecedência e acurácia. Este artigo Leia mais…
Abstract: This paper presents unpublished results and analysis of data collected in a survey with survivors of the Kiss nightclub fire. The goal is to better understand their behavior and the factors that influenced in the evacuation process on the night of the fire. The survey started in July 2019 Leia mais…
Abstract: Moisture in buildings is a complex issue involving vapor pressure, relative humidity, and the thermal aspects of building materials. Therefore, the climate, the construction system and the layout design of dwellings have a signif-icant influence on mold growth. This study investigates indoor humidity issues in wood frame social housing Leia mais…
Abstract: The increasing demand for renewable energy in industrial and agro-industrial sectors has 17 encouraged the substitution of fossil fuels by lignocellulosic biomass in cogeneration systems. In 18 this context, the residues generated in the palm oil agroindustry – specifically palm mesocarp fiber 19 and palm empty fruit bunch fiber Leia mais…
Abstract: Energy generation from renewable resources has grown in recent years due to the need to reduce the use of petroleum derivatives for economic and environmental reasons. Solid biofuels have proven to be an alternative for both electricity production and the transportation sector. To efficiently utilize these materials in their Leia mais…
Abstract: Agricultural biomass residues represent viable and sustainable energy alternatives, contributing to the mitigation of atmospheric emissions, rural development, and the transition to a low-carbon economy. Brazil has great potential for energy use from this residue, but to achieve this, it is necessary to understand its composition. Obtaining this information Leia mais…
