Franciscan Monastery in Pisa, 2009
During a break of Ecotrib sessions, Pisa, 2009

The biennial European Conference on Tribology ECOTRIB 2009, June 2009, has taken place in Pisa, Italy.

The city of Pisa is situated in western Tuscany, not far from the Mediterranean Sea. Its urban plan of reduced dimensions presents continuous testimony of historical events and cultural epochs that reflects its millenary development. Thus, within the medieval heart of the city, archaeological findings emerge from the Etruscan and Roman Pisa, and monuments have been standing since it was a Maritime Republic. The Conference was held in the recently restored building F of the Engineering Faculty of the University of Pisa, a few hundreds metres from the well known Piazza dei Miracoli and its Leaning Tower.

The 2nd European Conference on Tribology (ECOTRIB 2009) is the second biennial Conference primarily focused on the economy and industrial landscape of central and southern Europe. This event is co-organized by the Italian Tribology Association, the Austrian Tribology Society, the Slovenian Society for Tribology, and Swiss Tribology. The Conference coincides also with the 7th AIMETA International Tribology Conference (AITC), organised by the Tribology Group of AIMETA that merged in this Conference since 2007.

ECOTRIB 2009 provided an international forum for researchers from industry and academia to discuss the latest developments in Tribology, covering friction, wear and lubrication. Tribology bears on almost every aspect of our daily lives. It is the underpinning science and technology which has the potential to impact positively on all aspects of our health, wealth and quality of life, including how we generate and conserve energy, reduce friction and wear, and preserve our environment. The purpose of ECOTRIB is to offer an opportunity to examine the state of the art and a perspective of scientific and technological achievements in selected areas through invited speakers. Conference aims are also to provide researchers with a forum to present their findings and to provide practitioners with a way to relate their experience and solutions to specific topics.

Assoc. Prof. Dr. Emilia Assenova and Assoc. Prof. Dr. Mara Kandeva participated at the Conference ECOTRIB’2009 with 2 paper presentations.



On 19–21 January 2010 in Stuttgart /Ostfildern, Germany the 17-th International Colloquium on Tribology "Solving Friction and Wear Problems" was organized by the Technische Akademie Esslingen ( under the chairmanship of Prof. Dr. Wilfried J. Bartz.

17. Tribology Colloquium, Ostfildern, 2010
Exhibition Room

The Colloquium focuses on discussing and solving tribological problems connected to practice. For 45 years "Tribology" as a term related to friction, wear, and lubrication has found its way into the awareness of numerous experts who are concerned with the unacceptable effects of friction and wear, and who have to find solutions to minimize these effects. It has become clear that the lubricant alone is insufficient to solve the relevant problems. On the contrary, it is the last link in the chain that begins with the designing of the tribological contact and includes materials selection, metal cutting, and forming as well as surface treatment. Much has been achieved in these years but quite a number of questions still wait for satisfactory solutions.

For this purpose, this colloquium aims at facilitating the exchange of expert knowledge from all over the world. Bulgaria has been presented with 4 papers by 3 delegates - Prof. DSc Georgi Mishev, Assoc. Prof. Dr Emilia Essenova and Ass. Prof. Stefan Dishliev.

The actualized status of Balkan Tribological Association : Until now, six countries are members of the Balkan Tribological Association (BTA), Bulgaria, FYROM, Greece, Romania, Serbia and Turkey. An invitation to other countries such as of Albania, Bosnia-Herzegovina, Croatia, Cyprus, Russia, Slovenia should be sent, for becoming members of BTA. Each BTA member country of should investigate for contact persons in these potential candidate countries. It was suggested, that Professor Bouzakis receive this information and send invitation letters. In case of new entries, the BTA Board to be changed.

Information about the Journal of BTA: The impact factor of the journal is 0,182 (2011), rising from 0,101 in 2008, due to high scientific level of the papers published. The publishing of larger papers’ number was proposed for increasing the impact factor. As far as some statistics are concerned, 60% of the papers come from Balkan countries and the rest 40% from other countries worldwide. Manuscripts from 47 different countries have been published, with the majority dealing with chemicals. The scientific areas should cover other categories too, such as Mechanics, Bio-engineering, Surface Engineering, etc. Turkey has stated that the papers have to be reviewed strictly, since the papers’ scientific level increases the journal quality and the impact factor as well. Promotion via Internet. A journal website, with facilities of electronic paper submission should be created. Prof. Mitrovic expresses his interest to create a first version of the website of BTA. The financial matters were also discussed.

Lunch time

International School in Tribology (IST) and Statute of BTA. Professor Manolov and Professor Kandeva highlighted the planned International School in Tribology (IST) and some changes in the Statute of BTA, as it was discussed in the previous BTA-Meeting in Sozopol, Bulgaria, September 2010. Since all countries of BTA have not received the minutes from the Board Meeting in Sozopol, including discussions for the International School in Tribology, it was proposed, this issue to be discussed in a meeting organized especially for this purpose. The Bulgarian delegation insisted on making a decision concerning the operation of IST. Since all other delegates were not prepared for making a decision, they will receive information and decide whether they participate to IST and under which conditions. Decision should be taken at the next Meeting of BTA. Bulgaria passed the mandate of chairmanship of BTA to the Greek party for the next three years. For the period 2011-2014 the President of BTA will be Prof. K.-D. Bouzakis, Vice-president will be Prof. A. Mihailidis, both of the Aristoteles University in Thessaloniki. It has been decided that all questions related to BTA should be addressed to Prof. K.-D. Bouzakis. A decision was taken that the next conference BALKANTRIB’14 should be in Romania. The next meeting of the Managing Committee of BTA should be organized in 2012 by the Laboratory for Machine Tools and Manufacturing Engineering (EEΔΜ) at the Aristoteles University, Thessaloniki.

Now, 37 years after the launch of the word TRIBOLOGY in Bulgaria, the ideas of tribology have still not found pace in the development of science and technology in a persuasive manner. Tribology seeks more and more adherents. It is necessary a well-built Contact Network to be established in our country and in the Balkans in the sphere of tribology and the interdisciplinary sciences, having disposal of teams of specialists, which know and can solve tribological problems, and have the willingness to share this knowledge and skills with others who need them and are ready to learn how to solve problems. To have advanced information in the field of tribology. To know tribology. And to need it. To know where to find it, how to find it, whom to ask about it. Then to know what to do with it. Let us encourage those who seek solutions. To shorten the distance between us, between us and the business, between us and the governmental and non-profit organizations. Not to begin every time from zero, but to use the existing and gathered knowledge, and the experience on hand. In order that our way be easier.
