Laser Materials Processing Virtual Forum
Managed by Dr. Milton Lima, Photonics Group / Institute for Advanced Studies (IEAv), Aerospace Technological Center (CTA), SŃo JosÚ dos Campos - SP, Brazil.  See the  Forum folder  !

This forum - a source of technical, product and service information about industrial lasers and their applications, and as a discussion medium between laser experts and the materials community worldwide - discussed all aspects of laser-material interactions and processes, including: (i) Basic light-matter interactions ; (ii) Calculation and experimentation on heat transfer during laser processing ; (iii) Laser machining (cutting, drilling, marking, scribing, etc.) ; (iv) Laser welding ; (v) Laser surface treatment ; (vi) Ultra-short pulse processing ; (vii) Laser rapid prototyping ; (viii) Laser safety and practices ; (ix) New trends and developments in laser processing.

Cement Forum
Held on November 20-22 / 2000, in Beijing, People's Republic of China. The conclusions and recommendations from this event are transcribed in the "Beijing Declaration 2000".

Copper Forum
Held on October 23 - November 3 / 1999, in Portugal and Spain. A joint initiative from IMAAC and CYTED that has given opportunity for international experts to meet, discuss and propose solutions to the challenges posed by the sustainability in the mineral extraction industry. This Forum emphasized the copper case, with the specific focus at copper-pyrite zones of the southern part of the Iberian Peninsula - the largest copper producing area in Europe. "Technological Challenges Posed by Sustainable Development : The Mineral Extraction Industries" - a book edited by Villas B˘as and Fellows Filho - is the result of the discussions and reflections held in the course of the mentioned event.
