the conditions for the refinement of clarified sugarcane juice, including temperature (50o, 60o and 70oc) and pressure (0, 0.5, 1 and 1.5 bars) by micro-filtration membrane technology were investigated. the raw sugarcane juice was initially pre-filtrated with lime and then the juice obtained (clarified juice) processed using a ceramic micro-filter mem-brane (0.2 micrometer). the characteristics...

The aim of this study was to investigate the influence of light source, LED unit and halogen lamp (HL), on the effectiveness of Enforce dual-cured cement cured under a ceramic disc. Three exposure times (60, 80 and 120 s) were also evaluated. Two experimental groups, in which the polymerization of the dual-cured cement was performed through a ceramic disc, and two control groups, in which the p...

We reviewed the results of 70 total hip replacements utilizing a modern ceramic on ceramic total hip prosthesis in 60 patients. The age of the selected patients ranged from 25 to 76 years (mean, 46 years). The diagnoses at the time of implantation were osteoarthritis (33 patients), avascular necrosis (29 patients), developmental hip dysplasia (four patients), rheumatoid arthritis (one), and pos...

• Research, develop and demonstrate the Ion Transport Membrane (ITM) Syngas ceramic membrane reactor system for the low-cost conversion of natural gas to hydrogen and synthesis gas. • Scale-up the ITM Syngas reactor technology through three levels of pilot-scale testing and precommercial demonstration. • Obtain the technical, engineering, operating and economic data necessary for the final step...

Hydrogen as a high-quality and clean energy carrier has attracted renewed and ever-increasing attention around the world in recent years, mainly due to developments in fuel cells and environmental pressures including climate change issues. In thermochemical processes for hydrogen production from fossil fuels, separation and purification is a critical technology. Where water-gas shift reaction i...

in medieval islamic persia, mina was known as a general term for enameling on metal, glass and ceramic. consequently, in modern times mina’i is one of the most important types of islamic ceramic production and identified by stone paste body and multicolored polychrome over-glazes which represent figural, geometric and floral designs as well as calligraphic perform. additionally, mina’i wares ar...

The Mesopotamian invention of suspended narratives in mineral pigment and glaze produced in the fifteen thousand year old ‘new technology’ of the ceramic tile sets the scene for my talk for EVA 2010 (and this published paper which is intended to act as a prologue to that talk). It was this invention, a mass-produced media technology with the limit of a prototype glass screen that allowed commen...
