3. CARACTERIZAÇÃO FÍSICA E QUÍMICA DA BIOMASSA USADA COMO COMBUSTÍVEL SÓLIDO EM UMA CALDEIRA
Biomass is a renewable energy source most used in the world, however, depending on the chemical properties and origin of the material used as biofuel, the amount of ash generated during combustion can be high, harming the energetic harnessing. The objective of this study was to characterize chemically and physically biomass: bark, sawdust, and urban pruning;

4. Open Science and the Role of Cardiology Journals in the COVID-19 Pandemic
In the current search for renewable energy sources, residual biomass has gained ground in the concept of biorefinery. Furanic compounds such as 5-hydroxymethylfurfural (HMF), furfural (FF) and derivatives such as levulinic acid (LA), obtained from biomass, have emerged as important industrial chemical platforms. In this sense, this work aimed to use pequi ba

9. Study of the Potential of Photovoltaic Microgeneration and Minigeneration from the Grid-Connected Photovoltaic Systems Installed at UTFPR Curitiba Campus
Abstract: Humanity is increasingly dependent on energy, which demand grows every year. Renewable energy sources are consolidated alternatives in the market, previously installed on a small scale but now thought as large plants. The correct operation, taking full advantage of the generation potential, depends on studies of the place of implantation, such as r
