Dragan Uskokovic, President of Yugoslav Materials Research Society and Director of the Institute of Technical Sciences of SASA at the Eighth Conference of Yugoslav Materials Research Society YUCOMAT 2006, Herceg Novi, September 4th, 2006 Honourable ladies and gentlemen, dear colleagues, I have a great honour and pleasure to greet you in the name of the Yugoslav Materials Research Society and the Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, at the beginning of the Eighth YUCOMAT Conference and to wish that the program in front of you be the source of new information and useful discussions.
Previous seven conferences, held since 1995, and their Proceedings published by Trans Tech Publications from Switzerland in their Materials Science Forum Edition, are visible proof of the path we have come through.
YUCOMAT Conferences played a significant role in the development of materials science in our country.
As you may see from this year's Conference Programme, three Plenary Sessions and five one-day Symposia are planned to be held, dedicated to advanced methods in materials synthesis and processing, advanced materials for high-technology application, nanostructured materials, composites and biomaterials.
Proceedings of this, as for the previous seven conferences, will be published by Trans Tech Publication Ltd, Zürich, Switzerland, in its Materials Science Forum Edition in English, thus adequately presenting our scientists and the whole manifestation to the world.

The structure parameters of the tower are: the height is 78 m, the bottom diameter is 4.23 m, the top diameter is 2.98 m, Q345 steel is used for tower material, material density is 7850 kg/m3, elastic modulus is 2.06×1011 Pa, material density of foundation concrete is 2600kg/m3.
Therefore, light composite materials are used in the design and construction of the hub and blades to control the mass of the nacelle and improve foundation elasticity, thus avoiding resonance due to the closeness of the rotor working frequency and the tower natural frequency, and ensuring the safe operation of the wind turbine.

Introduction With gob-side entry retaining Technology in Coal Mining Project [1], the materials research of backfill for mine gateway side and development to become the focus of attention.
As a roadside packing materials must be compatible with the mining schedule, which along with coal mining for roadside packing material must have a certain carrying capacity, as mining operations continued operation when the 24-hour shifts, which means that roadside packing material in 16~24 hours must have the appropriate capacity, so the development of a high early strength can be pumped roadside packing material as necessary.
Raw materials and test methods Raw materials Mechanical calculation based on the engineering project needs and need concrete strength grade C30, but the early strength to meet the 16-hour requirement can hold charge, or 8 hours to form removal, 16 hours to reach the design strength of 20%, 24 hours to reach the design strength 40% of the material for this choice are as follows: (1) Cement: When the real estate license in the United 42.5R ordinary portland cement

(1) The thermal physical parameters of melt in casting zone are only determined by temperature. (2) The physical parameters of roller are constant. (3) The physical and inertial force are neglected. (4) There is no relative slide between solidification-shells and rollers, and they contact tightly. (5) The elastic deformation of the material is relatively small to the plastic deformation, thus it can be ignored. (6) The materials volume can not be compressed. (7) The materials are isotropic and homogeneous
