Influence of drag and turbulence modelling on CFD predictions of solid liquid suspensions in stirred vessels

2014

Abstract Suspensions of solid particles into liquids within industrial stirred tanks are frequently carried out at an impeller speed lower than the minimum required for complete suspension conditions. This choice allows power savings which usually overcome the drawback of a smaller particle-liquid interfacial area. Despite this attractive economical perspective, only limited attention has been paid so far to the modelling of the partial suspension regime. In the present work two different baffled tanks stirred by Rushton turbines were simulated by employing the Eulerian-Eulerian Multi Fluid Model (MFM) along with either the Sliding Grid algorithm (transient simulations) or the Multiple Refe…

Electrically conductive hydrogel composites made of polyaniline nanoparticles and poly(N-vinyl-2-pyrrolidone)

2006

Abstract A novel electrically conductive composite material, consisting of polyaniline (PANI) nanoparticles dispersed in a polyvinyl pyrrolidone (PVP) hydrogel, was prepared ‘in situ’ by water dispersion polymerisation (DP) of aniline using PVP as steric stabiliser, followed by γ-irradiation induced crosslinking of the PVP component. Conversion yield of aniline into PANI particles was determined via HPLC and gas chromatography, while structural confirmation of the synthesised polymer was sought by FTIR. Morphology and dimensions of PANI particles into the coloured, optically transparent hydrogel was determined by electronic microscopy; moreover, swelling behaviour of composite hydrogels in …

Optical properties of biocompatible polyaniline nano-composites

2006

Abstract Polyaniline (PANI) is an electro-active polymer of great interest thanks to its outstanding physical and chemical properties which make it suitable for various applications in optics, bioelectronics, biosensors, diagnostics and therapeutic devices. Unfortunately, PANI is infusible and insoluble in most common solvents and, thus, very difficult to process. In the attempt of improving processability, yet preserving its interesting properties, PANI has been synthesized in the form of particles and dispersed into a hydrogel matrix. The synthesis of PANI–hydrogel composites proceeds via γ-irradiation of PANI dispersions as obtained by ‘in situ’ polymerization of aniline in the presence …

La muerte de Joan Feliu. Sospechas y temores en el reino de Valencia a fines del siglo XVI

2010

El homicidio de un labrador en una comarca rural valenciana a fines del siglo XVI sacó a la luz algunos de los recelos que había entre cristianos viejos y moriscos. En este trabajo analizamos las investigaciones que se llevaron a cabo para resolver el caso y cómo esos recelos influyeron sobre las jurisdicciones que se hicieron cargo del mismo. (A)

Fractal dimension confidence interval estimation of epicentral distributions

1999

Estimates of the fractal dimension of hypocentral distributions require evaluating the range of independent variables in which fractal parameters exhibit a power law. Systematic and accidental errors are produced mainly by the subjective selection of this range, the insufficiency of data sets as well as by hypocenter mislocations. Therefore it is very important to determine the confidence intervals which are associated with fractal dimension estimates. The effects of various sources of errors are studied using different geometric clusters of epicenters, which have been synthetically generated using a multicluster algorithm with different hierarchical levels, so as to reproduce some characte…

Le politiche per lo sviluppo tra diritto interno e diritto comunitario

2002

Il vincolo comunitario sul governo dell'economia ha avuto refluenze importanti sul modo di intendere la costituzione economica. La monografia prende in esame le questioni sull'ordine giuridico del mercato, approfondendo in particolare la problematica dei rapporti tra concorrenza e coesione nelle politiche regionali per lo sviluppo.

Transactions in Mobile Electronic Commerce

2000

With the development of global networking, invention of WWW, and proliferation of Internet-enabled computer hardware and software into homes and pockets, a huge customer base has been created for electronic commerce. It is rapidly expanding in USA and Europe and Japan are following the trend. So far, the development of E-commerce has happened in a rather unregulated way especially in USA, whereas in Europe the European Commission has been developing a regulatory basis mainly in form of directives. Currently (12/1999) they have not yet all been accepted and a major restructuring of the regulatory framework has also been planned. Another technological development is the rapid growth of mobile…
