This Month's Introduction
This Month's Issue features NDT in Infrastructure in conjunction with the international Symposium NDTISS'99. We are pleased to introduce Edouard G. Nesvijski as virtual chairman of This Month's Forum. Mr. Nesvijski was active in the Organizing and Scientific Committees of  NDTISS'99 in Brazil. Have a look at the Report on the NDTISS'99

As usual,  this Month's Issue also features articles on miscellaneous NDT topics, in particular Yoseph Bar-Cohen's article Emerging NDE Technologies and Challenges at the Beginning of the 3rd Millennium -- Part II .
