Instruments to promote renewable energy in the German heat market—Renewable Heat Sources Act

In order to promote the sustainable growth of renewable energies in the German heat market, strong political impulses equivalent to the German Renewable Energy Sources Act for the electrical power market and the exemption of biodiesel from the German petroleum tax for the fuel market are required. The requirements on and possible designs of a Renewable Heat Sources Act to meet this need are presented and discussed.     

车用发动机主要噪声源的声强测试方法研究

作者对一台车用高速增压柴油机的辐射噪声进行了测量试验，掌握了该发动机表面噪声级随发动机工况变化的规律，并以发动机前端为例，利用声强法进行了发动机主要噪声源的识别研究，为降低该型发动机的表面辐射噪声提供了有效的参考依据。作者还将声强测量结果与振动测量结果进行了比较，两者的结论是一致的，证明直接利用表面辐射声强信号识别发动机主要噪声源的方法是可靠的。     

Prof. S. Shcheklein – One of the founders of the scientific and methodical school of energy saving,increasing energy efficiency and hydrogen energy in the Urals

The article gives the main results of scientific and educational activities of a prominent and well-known scientist in the field of energy saving and energy efficiency improvement, hydrogen energy, development of methods and technologies for the use of renewable energy sources, environmentally efficient projects, head of the Department of Nuclear Power Plants and Renewable Energy Sources of Ural Federal University (UrFU), Honored Power Engineer of Russia, Full Member of the International Energy Academy, Dr. Tech. Sciences, Professor Sergei Shcheklein. It is shown the achievements of the Ural Scientific and Methodological School in this area of knowledge, as well as the history of the creation of the first in Russia Department of Energy Saving at UrFU, the Center for the Training and Certification of Specialists in the Field of Energy Saving, the Regional Educational and Methodological Center for Energy Saving. The results of the work of the Interuniversity Coordination Council on Energy Saving in educational institutions of the Ural Region under the Regional Energy Commission of the Government of the Sverdlovsk Region on the implementation of the Energy Saving Program of the Ministry of Education of the Russian Federation in 1999–2005 are described. The article expounds twenty years of experience in organizing and holding all-Russian, and recently – international student olympiads, youth scientific and practical conferences, exhibitions of scientific and technical creativity of students, graduate students and young scientists on energy and resource saving, renewable energy sources and nuclear energy. We have presented some results of scientific research of the laboratory “Eurasian Center for Renewable Energy and Energy Saving”, created and operated under the guidance of prof. Sergei Shcheklein and described briefly the textbooks published in recent years in the field of hydrogen energy, on the safe use of nuclear energy at modern and promising nuclear power plants, the development of a methodology for calculating complex energy systems based on the use of renewable energy sources, the classification of renewable energy clusters, performed in collaboration and under the guidance of prof. Sergei Shcheklein. Moreover, references to the main federal and regional regulatory documents, scientific publications and educational publications related to the scientist's many years of work in this area, scientometric indicators are given.

FCo70-YQ型放射源运输容器耐热试验

FCo70-YQ型放射源运输容器是设计用于运输60Co和137Cs的医用放射源运输容器,设计容器最高装源活度60Co不超过12000C(i444TBq),137Cs不超过8000C(i296TBq)。根据国家标准《放射性物质安全运输规程》(GB 11806ˉ2004)的要求,对FCo70ˉYQ型容器进行了耐热试验。试验中测量到容器本体的最高温度为193.9℃,小于容器屏蔽材料铅的熔点温度327.3℃。试验结果证明了FCo70-YQ型容器热工设计满足国家标准《放射性物质安全运输规程》(GB 11806-2004)的要求。     

Sustainable energy planning by using multi-criteria analysis application in the island of Crete

The sustainable energy planning includes a variety of objectives, as the decision-making is directly related to the processes of analysis and management of different types of information (technological, environmental, economic and social). Very often, the traditional evaluation methods, such as the cost-benefit analysis and macro-economic indicators, are not sufficient to integrate all the elements included in an environmentally thorough energy plan. On the contrary the multiple criteria methods provide a tool, which is more appropriate to assemble and to handle a wide range of variables that is evaluated in different ways and thus offer valid decision support.

Analytical model of a superluminescent diode

Using a set of traveling wave rate equations ,a superluminescent diode with a low facet reflectivity is studied .Analytical expressions of the distribu-tions of carrier density ,forward-and backward-propagation photon densities,and gain are obtained at different facet reflectivities.It is shown that the high nonuni-form carrier distribution is evident in the case of low facet reflectivity.The results can serve as useful guides in understanding emission mechanism of superlumi-nescent diodes.
