Resonance transformer design is a large-scale and complicated management process. With the improvement of science and technology in China, and the application of modern professional, factory, mechanical and information means provides sufficient science and technology basis for the transformer design level. Grounded in the environment of electronic linear accelerator, this thesis could change the current situation of imperfect transformer management. This thesis elaborates the background and significance of electronic linear accelerator in resonance transformer design, proposes the purpose and main content mode of resonance transformer design, gives a detailed introduction of the frame and functions of all modules of PSCAD simulation experiment, and finally makes relevant discussions of the application of resonance transformer.

Purpose To define strategic directions for the Russia’s social, economic, scientific and technological development in 2011-2013, a large-scale foresight study including the deep analysis of prospects of biotechnology development there was undertaken (Russia 2030: Science and Technology Foresight). This paper aims to present results of this research. Design/methodology/approach The study was based on a combination of technology-push and market-pull approaches that aimed not only to identify most promising science and technology (S&T) areas but also to understand how they can be realized in practice. Representatives from federal authorities, science and business were involved in the project to create future visions of technological directions; analyze grand challenges, weak signals and wild cards; and set research and development (R&D) priorities. Findings According to results of the study, Russia has a potential for biotech sector development, although the level of R&D in the majority of areas is lagging behind that in the USA and leading EU countries. However, there are several advanced applied research areas where efforts can be focused. Among them are high-performance genomics and post-genomics research platforms, systems and structural biology, microbial metabolic engineering, plant biotechnology and microbial strains and consortia for development of symbiotic plant–microbial communities. Originality/value Concentration of available resources of government and business on biotechnological sector development can help to find answers for challenges that Russia faces today or will face tomorrow. It will help to pick up on the current level of research activities, improve the quality of personnel training, make this area the engine of the economy and carry out the so-called new industrialization of the country, building a new, high-tech device industry.

Accident Management

Presented are experiment results of the Large Scale Test Facility (LSTF) conducted at the Japan Atomic Energy Agency (JAEA) with a focus on core exit thermocouple (CET) performance to detect core overheat during a vessel top break loss-of-coolant accident (LOCA) simulation experiment. The CET temperatures are used to start accident management (AM) action to quickly depressurize steam generator (SG) secondary sides in case of core temperature excursion. Test 6-1 is the first test of the OECD/NEA ROSA Project started in 2005, simulating withdraw of a control rod drive mechanism penetration nozzle at the vessel top head. The break size is equivalent to 1.9% cold leg break. The AM action was initiated when CET temperature rose up to 623K. There was no reflux water fallback onto the CETs during the core heat-up period. The core overheat, however, was detected with a time delay of about 230s. In addition, a large temperature discrepancy was observed between the CETs and the hottest core region. This paper clarifies the reasons of time delay and temperature discrepancy between the CETs and heated core during boil-off including three-dimensional steam flows in the core and core exit. The paper discusses applicability of the LSTF CET performance to pressurized water reactor (PWR) conditions and a possibility of alternative indicators for earlier AM action than in Test 6-1 is studied by using symptom-based plant parameters such as a reactor vessel water level detection.

Dayah (Islamic boarding school) is the oldest institution in Aceh. It has a positive contribution toward citizen’s capacity building of Aceh, especially in the context of internalizing the Islamic teaching that acts as a social control in Aceh community. Formerly, the form of education in dayah still follow a traditional system, yet, along with the massive development of science and technology, it has adapted with the current situation without ignoring the old system. Many changes occur either in its physic and non-physic form.

Given the advances in science and technology, rapid development of socialist market economy and continuous advance of urbanization, it is necessary to enlarge the scale of engineering construction. As the form of engineering structure becomes more complex, large-scale and high-level projects with deep foundation have appeared in engineering construction. For construction engineering, one of its technologies includes solving the difficulties in construction. It is required to deal with the safety risk of construction in time to guarantee safety construction, timely solve the management difficulties and contradictory problems of the project and ensure both the safety of engineering construction and the rationalization of the institution setting of the safety supervision on the project.

This paper provided an overview that the city should be designed from the functional, connectivity, accessibility and other aspects of the city considering the current situation of obsolete facility and out of order around the Shanghai West Railway Station. It emphasized that the resources of Shanghai West Railway Station’s Zhenru area shall be integrated while the Zhenru center of Shanghai in Caoyang-street and the railway cargo terminal should be built. It proposed that the city should put emphasize on the development of modern logistics industry along with the construction of business office area, large-scale logistics enterprises gather, hotel service area and low density of cultural facilities.

In this paper, the authors analyze the current situation of agricultural production in Vietnam and affirm that fragmentation is one of the basic causes leading to ineffective potentials and low labor productivity. Based on this, the authors propose a number of solutions to convert small-scale production to large-scale production in order to improve labor productivity and optimally exploit resources in the agricultural sector in Vietnam today.
