This Month's Introduction
NDT of composites is the theme of this month's issue. Thanks to the ICAC'98 (Egypt, December '98) we are able to provide 6 articles from this conference. Also,  we'll continue our special series on the PACNDT '98 with some NDT Research Topics related to composites. We'll have more PACNDT articles  in our next issue.

Discussion Forums are a great advantage of the Internet. NDTnet maximizes opportunities for users to meet and expand their networks of professional contacts.
With that in mind, we've added Participants' and Authors' Profiles  in an attempt to compensate for the lack of face to face contact in cyberspace. Along with their future messages that profile icon will appear.
