Granulation is generally performed in a stirred vessel, by spraying binders onto row materials stirring the particles. However, the conventional granulation system has some problems. First, there are double peaks in the particle diameter distribution that degrade the quality of final products. Second, it takes too long time to determine the operating and producing conditions for a desired parti...

The present paper compares the simulated and measured radiation efficiency of a dielectrically loaded microstrip-fed Ultra-Wideband (UWB) monopole. The antenna was designed to operate inside a Universal Serial Bus (USB) dongle. Wideband efficiency measurements were conducted using the reverberation chamber technique and a cavity-based approach, called the source-stirred method. Both procedures ...

Abstract: The selection of a suitable type of reactor for the reaction with enzymes immobilized on the carriers is extremely important to industry. In this study the possibility of using pre-selected cellulose-based carriers (Granocel) to conduct the reaction in a stirred batch reactor and a fixed-bed reactor was investigated. It was shown that non-activated Granocel did not undergo compression...

In the present work an experimental investigation was conducted to obtain a correlation for the determination of convective heat transfer coefficients of stirred yoghurt in a plate heat exchanger. A rheological study was carried out in order to characterise the stirred yoghurt flow behaviour, evaluating its dependency both on shear rate and temperature. A shift in the temperature dependency was...

This review describes the historical development and current state of metals leaching and sulfide mineral biooxidation by the minerals industries. During the past 20 years commercial processes employing microorganisms for mineral recovery have progressed from rather uncontrolled copper dump leaching to mineral oxidation and leaching in designed bioheaps for oxidation of refractory gold ores and...
