Abstract The passion fruit juice production generates around 70% of by-products comprising rind, seeds and arils that are commonly discarded. consist 4% weight with the potential to produce 2,500 ton/year high added-value oil in Brazil. In this work, from different manufacturers effect seed moisture were evaluated towards quality extraction efficiency, using a continuous expeller press 100 kg/h...

Abstract Synthetic rocks are used in laboratories to measure the physical and chemical properties of Earth’s constituent minerals order understand interior. To phenomena middle upper crust, dense aggregates Na-rich plagioclase necessary. Therefore, we explored a method fabricating albite with low porosities, homogeneous microstructures, absence melt sample sizes larger than cubic centimetre usi...

In this study, carbide-forming metallic additives (W, Mo, Cr, Ti) were introduced into the copper matrix to improve wettability of diamond particles in copper–diamond composites. The samples prepared by Spark Plasma Sintering (SPS) and Hot Pressing (HP) at 920 °C. phase composition, microstructure thermal conductivity investigated. influence additive concentration, sintering method as well natu...

Current technical discussions of Internet privacy are often discussions about the hypertext protocol stack and things that people are doing with it: HTTP, HTTPS, JavaScript, HTML5, Flash/Silverlight/JVM, social networking and (partially) geolocation. Although there are other subjects that probably deserve just as much attention — such as wireless protocols and mobile devices — this position pap...

Sequential press forming of thin sheets is a method in which different locations within single workpiece are pressed sequence, and used to manufacture large structures, such as storage tanks. In the sequential forming, it important estimate bending-defect areas efficiently because product shape can be corrected not by repairing dies but only re-pressing subsequent process. At present, high skil...

Bending angle obtained in laser forming process is much smaller than that conventional die pressing or roller bending processes. Therefore, multi-stage necessary to form deep drawn shapes and/or complex by forming. However, irradiation varies material properties, posture, and stiffness of metal plates, those influences are accumulated during the consecutive stages process. Thus, thermo-elasto-p...

ceramic ultrafiltration membranes are considered as an alternative for the treatment of both stable water-in-oil and oil-in-water emulsions proved to be more effective in comparison with other conventional techniques. in this study, symmetric macro-porous ceramic membranes are prepared through dry pressing of α-alumina powder and the addition of various binders including poly (vinyl alcohol). t...

Abstract Textured hexagonal boron nitride (h-BN) matrix composite ceramics were prepared by hot-pressing using different contents of 3Y 2 O 3 −5Al (molar ratio 3:5) as the sintering additive. During hot-pressing, liquid Y Al 5 12 (YAG) phase showing good wettability to h-BN grains was in situ formed through reaction between and , a coherent relationship YAG observed with $${\left[ {010} \right]...

The work carried out by the authors over the last decade on the processing, microstructural characterization and the mechanical behaviour of Mg alloys is reviewed. In particular, the potential for grain refinement and for the development of specific textures of large strain hot rolling (LSHR), equal channel angular pressing (ECAP) and accumulative roll bonding (ARB) is discussed. The recrystall...
