Images are produced from the best available original document The Fourth International Conference on Modern Problems of Nuclear Physics (MPNP-01) is organized jointly by Institute of Nuclear Physics of Uzbekistan Academy of Sciences, Scientific Association "Physics - Sun" of Uzbekistan Academy of Sciences, Institute of Applied Physics of Uzbekistan National University and Samarkand State University. Discussion of modern problems in fundamental and applied nuclear physics and physics of elementary particles, activation analysis, radiation physics of condensed matter becomes a tradition of nuclear physicists of Uzbekistan. Scientists and specialists meet each other on Uzbek land the fourth time, this is a follow-up of the conferences held in Tashkent in 1995, Samarkand in 1997 and Bukhara in 1999. This time this conference is dedicated to the l(/h Anniversary of Independence of Uzbekistan. As experience shows such meetings give impulse to more serious and deep investigation of the different branches of the science and help to extend its "geography". It is great pleasureto mention that the conference is attended by specialists and scientists pom 18 countries and this is becoming a regular one. , - - Tfte main aim of our regular conferences is to bring up the scientists of the Central Asia region and the international scientific community together and give, the opportunity to exchange ideas and experience, especially, on practical application of the recent scientific results. The conference leads to the extension of international scientific and technical relations with foreign scientists from different countries and to the definition of the main tendencies of the modern of fundamental and applied nuclear physics. The conference has become possible owing to the financial support of a large number of organizations. On behalf of the Organizing Committee we wish to express our gratitude to the following organizations: Uzbekistan Academy of Sciences The State Committee of Science and Technology RU Institute of Nuclear Physics of Uzbekistan Academy of Sciences Scientific Association "Physics - Sun " of Uzbekistan Academy of Sciences The Abdus Salam International Centre for Theoretical Physics, Italy "Chemotrade" GmH&Co.
