5. Properties and Morphology of Polypropylene/Big Bags Compounds
In this work, compounds based on two grades of polypropylene (PP), i.e., PP H503 or PP H103 with residues of Big bag fabrics (RBB) were processed in a corrotational twin screw extruder with RBB content ranging from 10% to 50% of the weight. Then, their thermal properties were investigated through Differential Scanning Calorimetry (DSC) and Thermogravimetry (

6. Impacto nas propriedades mecânicas do concreto curado sob baixas temperaturas
RESUMO O processo de cura das matrizes cimentícias é muito importante na determinação das suas propriedades no estado endurecido. Nessas circunstâncias, o concreto pode sofrer sérias avarias quando exposto às severas variações térmicas. As baixas temperaturas de cura em que as matrizes cimentícias são expostas podem influenciar nas propriedades n

7. Efecto de los parámetros de aplicación en recubrimientos de Ni-Cr-B-Fe-Si obtenidos por Flame Spray
ABSTRACT Surface damage of components in service is an issue of great industrial interest because of the costs associated to the replacement of certain critical components. There are several techniques to generate coatings, which provide increased resistance to a particular type of surface damage. In this way, it is achieved surface protection to different s

8. Pelletizing furnace refractory lining life cycle extension by applying thermography analysis and direct refractory injection
Abstract The induration furnace is one of the most important devices in the pellet production system. It is responsible for ensuring the quality of pellets produced, since a high level of thermal energy is necessary to reach the physical properties needed. Therefore, the refractory lining performance is important to guarantee the quality of pellets and to av

9. Effect of Thermal Treatment on the Dynamic Behaviors at a Fixed Loading Rate of Limestone in Quasi-vacuum and Air-filled Environments
Abstract Thermal damage in rock engineering occurs in the air-filled and quasi-vacuum environments of rock mass located near or far from the free surface. Meanwhile, dynamic loads are encountered frequently in engineering practice. In this study, 39 limestone samples are prepared, and a series of laboratory tests, including split Hopkinson pressure bar (SHP

10. Toughening of polystyrene using styrene-butadiene rubber (SBRr) waste from the shoe industry
Abstract The vulcanized rubber waste from the shoe industry causes environmental damage when it is incinerated or inappropriately discarded, turning this into a problem of major concern. Therefore, this study had as the main objective the Polystyrene (PS) toughening using different contents of white vulcanized styrene-butadiene rubber (SBRr) waste produced i

11. Application viability evaluation of the Minimum Quantity Lubrication coolant technique under different flow rates in Plunge Cylindrical Grinding of the ABNT 4340 steel with aluminum oxide wheel
Abstract The coolant delivery technique known as Minimal Quantity Lubrication (MQL) has been employed in machining since the end of the 20th Century and has gained considerable evidence in the last years as a viable alternative to the use of the conventional coolant technique (flood). Due to the low oil flow rate delivered by the MQL technique in grinding op

12. Ultrasound-assisted extraction of fructans from agave (Agave tequilana Weber var. azul) at different ultrasound powers and solid-liquid ratios
Abstract The effects of ultrasound-assisted extraction (UAE) at different ultrasound power densities (UPDs; 40, 80, and 120 mW/mL) and solid:liquid (S:L) ratio (1:2, 1:3, and 1:6) on the extraction of carbohydrates from Agave tequilana plant of different ages were evaluated. Extracts obtained (6- and 7-year-old plant) were analyzed in the yield of carbohydra
