In the present work a plasma reactor, filled with catalysts, called as plasma catalytic reactor, is studied for removal of oxides of nitrogen, total hydrocarbons and carbon monoxide. The experiments are conducted on an actual diesel engine exhaust at no-load and at different temperatures starting from room temperature to 300°C. The removal efficiencies of these pollutants are studied. The experiments are carried out with both con- ventional and non-conventional catalysts. The idea is to explore the pollutant removal efficiency characteristics by non-conventional catalysts. The efficiency results are compared with that of conventional catalysts. The experiments are carried out at a constant pulse repetition rate of 120 pps. Both pellet and honeycomb type catalysts are used in the study.展开更多

This article try to find out the problems that a teacher may come across when applying MI in the classroom through a case study about an unsuccessful teaching practice, and try to provide a solution as how to make use of MI in classroom correctly. The researcher's premise was that given what we were informed about the educational needs of second language learners, the teachers must be better aware of the students diversity and apply accordingly multifarious activities to suit students' linguistic, cultural and cognitive need. Results of the study indicated that students did have different preferred intelligences. However, if the MI based lesson was not conducted with enough preparation before hand, the students' diverse intelligence cannot be fully developed thus makes the theory failed to further implemented.展开更多

This paper tries to answer the questions mentioned above from the perspective of technology evolution. The industrial environment of emerging technology is emphasized for analyzing the endogenous innovation in Chinese enterprises. The process of endogenous innovation in NanShanBridge Co. Ltd （NSBIC）, which is an IC design firm, is analyzed as a case. From the case study, we can answer the questions above in certain extent, give some suggestions to the enterprises as a later-comer, and present some advice to government.展开更多

The report holds that: 1) The copyright law shall evolve with the times and be revised from time to time; 2) it is imperative to popularize and educate in the copyright law; 3) the guidelines for the use of the copyright law of the education industry shall be developed as soon as possible; and 4) the Collective Management of Copyright Regulations shall be enforced as early as possible.展开更多

The Rapid Profile tests a person's acquisition stage by morphology, syntax and lexis. The tasks in RP test are specially designed to trigger pre-defined indicators of second language development, who have their own characteristics. The aim is to examine whether it is possible to find some tricks for test takers to achieve a higher stage of acquisition than their real language development. The limitation and implication drawn from the study will also be investigated.展开更多

Recommendations for the protection of vegetation on and around the site, including control of the erosion and run off from the construction site were proposed and implemented, resulting in effective protection of the local vegetation cover. Stream macrobenthos were low in species diversity and abundance and did not show a changing trend during the construction and the operation of the land fill. Birds attracted to the active dumping site were dominated by Crested Mynah Acridotheres cristatellus and the Tree Sparrow Passer montanus. After an increase in the population during the warmer months, the number of birds seen on the land fill site decreased to 10 in December 1994. Mammal monitoring by live trapping revealed that the rat population did not increase after the land fill operation started. This project was the first comprehensive’ ecological study and monitoring of an urban land fill in Hong Kong and it demonstrated that careful environmental planning and implementation of mitigation measures can successfully limit environmental impacts of landfills to acceptable levels.展开更多

This innovative model of SJTU Library operation is not only in concert with the strategic goals of SJTU but also with two other conspicuous developmental trends in the larger academic library circle;namely, 1) a trend toward the deepening of library service support in academic arena on the one hand and 2) the trend of diversifying library outreach services on the other hand.Based on our first-hand involvement in all phases and aspects of this project and its subsequent review and analysis undertakings, this paper expatiates upon the IC2Culture Exploring Project of SJTU Library in terms of its vision, its specific mission objectives, its program design, its unique characteristics, its launching process, its salient case studies, its initial results and its strategies for a sustainable development in the future.展开更多

These difficulties are connected with the occurrence of many natural mining hazards and limitations resulting from the existing in this area surface infrastructure. One of the most important problems of Polish mining is the rock burst hazard and reliable evaluation of its condition. During long-years’ mining practice in Poland a comprehensive system of evaluation and control of this hazard was developed. In the paper the main aspects of rock burst hazard state evaluation will be presented, comprising: 1) rock mass inclination for rock bursts, i.e., rock strength properties investigation, comprehensive parametric evaluation of rock mass inclination for rock bursts, prognosis of seismic events induced by mining operations, methods of computer-aided modelling of stress and rock mass deformation parameters distribution, strategic rock mass classification under rock burst degrees; 2) immediate seismic and rock burst hazard state evaluation, i.e., low diameter test drilling method, seismologic and seismoacoustic method, comprehensive method of rock burst hazard state evaluation, non-standard methods of evaluation; 3) legal aspects of rock burst hazard state evaluation. Selected elements of the hazard state evaluation system are illustrated with specific practical examples of their application.展开更多

This study focuses on the role that weak, moisture-sensitive floor has in the instability issues.Previous NIOSH research related to this subject did not include analysis for weak floor or weak bands and recommended that when such issues arise they should be investigated further using a more advanced analysis. Therefore, to further investigate the observed instability occurring on a large scale at the Ohio mine, FLAC3 D numerical models were employed to demonstrate the effect that a weak floor has on roof and pillar stability. This case study will provide important information to limestone mine operators regarding the impact of weak floor causing the potential for roof collapse, pillar failure, and subsequent subsidence of the ground surface.展开更多
