FOREWORD

The Presidium`s Executive of ATSR gave us the mission to organize in Timisoara, the VIth edition of the Days of Academy of Technical Sciences in Romania (ATSR).

The branch of ATSR in Timisoara, a center of culture and science in the west zone of Romania, organized many scientific events, as seminars, technical conferences, workshops, and other meetings, having the aim to debate different problems of interest.

In the VIth edition of ATSR Days, we thought to organize an international conference concerning the actual important problems, and for this reason, we named it: PRO PROSPERITATE industry - energy - environment.

In order to approach the conference theme, they have been organized three types the debates:
• Invited lectures, sustained by the specialists from country and abroad;
• Dialogue - Seminar lectures, organized by ATSR sections, where there are presented the applied works in order to develop the approached field of activity;
• Poster papers - elaborated in the field of academic research, having the aim to evaluate the necessary possibilities to develop the science and technique in Romania.

The scientific papers, having the authors consent to be published, are presented in the Proceedings, edited by AGIR Publishing House.

We hope that every reader to find something interesting to apply and to develop new ideas in its field of activity.

The organization of "PRO PROSPERITATE" conference had an important ethic and financial support from different companies and institutions, those we send great thanks:
• Ministry of National Education, Bucharest;
• National Highways Company, Timisoara Branch;
• National R&D Institute of Welding and Material Testing, ISIM Timisoara.

Many thanks we send to the Presidium`s Executive of ATSR, which gave us an important aid, in organizing this conference.

We also, thanks to the members of ATSR, Timisoara Branch, who made possible this conference organization in very good conditions, and to all the authors of the scientific papers, presented in the conference.

The prosperity is indivisible, also the peace, which is for all of us.

President of Organizing Committee,
Prof. Dr. Eng. Marin TRUSCULESCU
Full Member of ATSR
