Equal channel multi angular pressing (ECMAP) process is the efficient method to enhance the productivity of ultra-fine grained (UFG) materials, by increasing process continuity and as a result decreasing process required time. Comparing repetitive ECAP method, in the same period, the number of passes can be done by ECMAP. In this article, ECMAP of AL strips in two typical annealed and as receiv...

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...

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...

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...

Hot Isostatic Pressing (HIP'ing) is one of several processes used for consolidating porous materials (such as metal powders) to high density. The equations describing the HIP'ing system dynamics are immensely complicated and highly nonlinear, thus complicating any controller design for the system. Further complications arise due to the fact that one of the system's states, grain size, cannot be...
