Evaluation of waste-energy process through the combustion and co-combustion of palm residual biomass

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…

Characterization pf relevant biomasses in the Brazilian agricultural scenario

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…

Enhancing combustion properties of elephant grass and palm empty fruit bunch fiber trhrough water leaching

Abstract: Elephant grass (EG) and palm empty fruit bunch fibre (EFB) have great potential for bioenergy. However, their high content of alkaline ash, chlorine and other contaminants hinders direct combustion by promoting slagging, fouling and pollutant emissions. To address this issue, the main goal of this study was to assess Leia mais…

Diretrizes de projeto para minimizar fissuras recorrentes em reservatórios de concreto armado para obras de saneamento = Design guidelines to minimize recurrent cracking in reinforced concrete tanks for sanitation infrastructure

Resumo: A frequente ocorrência de fissuras em reservatório de concreto armado destinados a obras de saneamento tem comprometido a segurança e o desempenho dessas estruturas. Este trabalho tem como objetivo reunir diretrizes de projeto que possam minimizar fissuras nestes reservatórios. Foi realizado um estudo comparativo entre projetos de reservatórios com Leia mais…

Avaliação da resistência mecânica da matriz de cimento em duas escalas físicas: influência do tamanho dos corpos de prova e da presença de areia = Evaluation of the mechanicalmtrength of the cement matrix at two physical scales: influence of specimen size and sand sresence

Resumo: Este estudo investigou a resistência à compressão da matriz cimentícia considerando a influência da escala dos corpos de prova e da presença de areia. Foram moldados corpos de prova cilíndricos de pasta de cimento CPV-ARI e de argamassa padronizada em duas dimensões (2,7×5,4 cm e 5×10 cm), ensaiados nas Leia mais…

Effect of prestraining and prolonged high-temperature exposure on y’ precipitate morphology incast CMSX-4 superalloy

Abstract: This study examines the morphological evolution of c0 precipitates in cast CMSX-4 single-crystal Ni-based superalloy subjected to prestraining at either 982 C or room temperature, followed by long-term high-temperature exposure (up to 1185 h at 982 C and 1088 h at 1150 C). Four initial conditions were evaluated: (1) Leia mais…

rBCG-LTAK63 enchances protection aginst tuberculosis by inducing autophagy and circadian gene regulation

Abstract: Tuberculosis (TB) remains a global public health challenge, with the current BCG vaccine providing limited efficacy in adults, and available treatments being lengthy and debilitating. To overcome these challenges, we have previously developed a recombinant BCG strain expressing the detoxified E. coli Heat-Labile Toxin (LTAK63), providing increased protection in Leia mais…
