DesignNet: a online knowledge gateway for industrial design education and research activities
This paper presents DesignNet, a knowledge-based system to the online digital display, retrieval and archiving of rich media resources for industrial design education and
research. It addresses the needs of end-users (teachers, researchers and students) and content providers interacting with the School of Design of the Politecnico di Milano. The project moves from the assumption that traditional modalities of archiving and presentation currently adopted by the Politecnico and other academic institutions are not coherent
with industrial design process and its need of project-support materials. The typical outputs
of industrial design process are 3D models or 2D graphics, not just texts or simple
images, the materials for which the usual method and technique of archiving and retrieval
are conceived and developed. The challenges, philosophy and methodology in creating
this evolving Web-based, cataloguing, multimedia knowledge-base to VR design resources
are discussed. Finally, the related system and prototype are described

Heavy Metals Retention On Recycled Waste Glass. A Comparative Study Among Different Species
Heavy metals retention [Pb2+, Cd2+, Ni2+, and Cr(VI)] on recycled waste porous glass (RWPG) from solid wastes
sorting operations was carried out. To the purpose metals containing solutions in the concentration range 24 mg/L, reproducing
the average concentration present in, e.g., solid waste leachate from landfills or industrial effluents, were percolated onto columns
loaded with RWPG beads with particle size in the range 0.351.0 mm and flow-rates between 0.23 and 0.75 L/h. Metals retention
mechanism was associated with ion exchange with overall capacities in the following order: Pb2+ > Cd2+ > Ni2+ > Cr(VI) in
consideration of the hydrated ion radius and free energy of hydration of the metal ions. The rate controlling step was identified with
the ions interdiffusion in the Nernst liquid film around particles. The metals exhausted beads were embedded into cement
conglomerates as inert materials thus minimizing metals release in the environment. The prepared mortar specimen showed
improved thermal properties as compared to conventional (sand based) composites
Recycled porous glass from municipal/industrial solid waste sorting operations as a lead ion sorbent from wastewaters
Recycled waste porous glass (RWPG), from municipal solid wastes (MSW) sorting operations, may be
used as a sorbent for lead ion removal from industrial wastewaters. To the purpose, dynamic (laboratory
columns) operations were carried-out by the use of differently sized glass beads in the range 0.35\u2013
1.25 mm which were eluted with lead ion containing synthetic solutions (2\u20139.5 mg/L). Temperature
was kept constant (298 K), whereas column flow-rates varied in the range 0.20\u20130.75 L/h. Lead ion retention
mechanism was associated to the adsorption/ion exchange phenomena. Best column performance
was obtained at 0.5\u20131 mm bead size range, influent concentration 2 mgPb2+/L and column flow-rate
0.20 L/h. In the reference conditions lead ion retention capacity exceeded 1.10 mg/g. Kinetic analysis of
the experimental data was also carried-out and film interdiffusion of the involved ions in the Nernst stationary
liquid around the particle was identified as the rate controlling step
