Resumo: TNos últimos anos, a construção civil vem passando por uma transformação digital, visando processos mais eficientes e colaborativos dentro e fora do canteiro de obras. O Last Planner System (LPS), sistema com origem na filosofia lean construction, é uma abordagem que se destaca por eliminar restrições e gargalos, bem Leia mais…
Abstract: Wireless communications with greater transmission capacities are possible in the millimeter wave (mmWave) region. However, to overcome the significant propagation losses in this frequency band, it is necessary to employ more efficient and intelligent antennas based on MIMO and beam-steering phased array technologies. This paper demonstrates the fabrication of Leia mais…
Abstract: Fructooligosaccharides (FOS) are fructose oligomers beneficial to human health and nutrition for prebiotic sugars. Their production occurs by a transfructosylation reaction in sucrose molecules catalyzed by fructosyltransferase enzymes (FTase, E.C.2.4.1.9) adhered to microbial cells. The purpose of this work was to study the preparation, enzymatic activity, and stability of Leia mais…
Abstract: Construction and demolition waste (CDW) worldwide generation accounts 10billion tonnes yearly. The major fraction is landfilled requiring innovative recycling methods to reduce the associated environmental impacts and to increase its circularity. Our study demonstrated the feasibility of using different CDW fines to develop recycled cements and optimized the content Leia mais…
Abstract: Excavations soils from construction sites, when included as Construction and Demolition Waste (CDW) can double waste amount and represent up to 80 % of waste composition. Limited recycling strategies are available for the material. In this work, soils with higher kaolinite contents were selected by X-ray diffraction (XRD) to Leia mais…
Abstract: White-rot fungi (WRF) synthesize ligninolytic extracellular oxidative enzymes such as laccase (Lcc), which has been described as one of the most interesting types of redox enzymes that can improve microbial fuel cell (MFC) performance. Therefore, and in order to test that performance, WRF Trametes versicolor MUM 04.100 was immobilized Leia mais…
Abstract: This study investigates the impact of the cooling rates, from 18 to 1.5 °C/s, on the as-cast microstructure of the CMSX-4 Ni-based superalloy, especially on morphological changes in primary γ′ precipitates in the dendrite core and border. Microstructural characterization along the height of directionally solidified samples included the measurement Leia mais…
Abstract: Fatigue behaviour of bcc Nb-48 wt%Ti (Ti-36at%Nb) alloy parts processed by Laser Powder Bed Fusion (L-PBF) using as raw material two different types of powders, spherical powder produced by Plasma Atomization (PA) and irregularly shaped powder produced by Hydride-Dehydride (HDH) process, are compared. Laser power and scanning speed were Leia mais…
Abstract: Electrospun nanofiber scaffolds mimic the structure of the natural extracellular matrix, making them promising for application in tissue engineering. Based on this, the biopolymers poly(ε-caprolactone) (PCL) and gelatin, with good mechanical and biological properties, respectively, were electrospun with acetic acid as the only solvent, without the crosslinking process in Leia mais…
