In addition to crustal earthquakes provided by catalogues, recent paleoseismological and neotectonic investigations have permitted to consider events which occurred during the last 400 years.Four seismogenic sources that could cause damages to the studied site corresponding to Precordillera,Western Sierras Pampeanas, Basement of the Cuyana Basin and Cordillera Principal were identified.Based on the evaluation of the contribution of these sources,maximum moment magnitudes above 7.5（Mw） are expected.High values of SA（spectral acceleration）（0.2 and 1 s periods） and PGA（peak ground acceleration） were found in the city of San Juan, which suggests that it is located in a zone of high seismic hazard.Finally, the obtained SA spectra were compared with the seismic-resistant construction standards of Argentina INPRES-CIRSOC 103 [1]. Results suggest that for the city of San Juan and for a return period of475 years, it covers the seismic requirements of the structures.展开更多

Chronometry method is one of the work study methods which is appropriate for recording shorter cyclic processes and is based on statistical sampling theory. Determination of cyclic times and work performances of standard cyclic construction machines （SCCM） is one of key assumptions of dynamic planning of machine work on every construction site. Calculation methods of SCCM work performances arc one of basic research objects in the field of construction organization and technology. Study shows applied chronometry method in work of standard cyclic construction machine. Goal of this study is to accomplish regulation through measured time cycle and compare measured effects with effects obtained with standard methodology of calculating hydraulic excavator practical achievement for gaining regulation in order to determine main reasons which effect work performance on site.展开更多

In recent years, mines have carried out a large number of beneficial scientific explorations and practices on production safety management. According to their own actuality, they have combined production safety with scientific management. They have done meticulously and solidly, ensuring that the safety situation continues to be good. There have been no serious injury accidents, let alone work-related accidents for two consecutive years. The injury rate of thousands of people is in the good results within the control index have also made it a benchmark for safety management in the nonferrous mines of Chinalco. This paper analyzes and discusses the scientific methods and good experiences of the production safety of Dahongshan Copper Mine from six aspects: explosion management, organizational security, infrastructure, safety inspection and quantitative mechanism, safety training, safety science and technology, etc. Finally, it gives suggestions for the next production safety of Dahongshan Copper Mine.展开更多

A national library law is currently being enacted while several local library legislations have already seen fruitful results. In the enactment of 'Regulations for the Protection of Information Network Dissemination Rights', the library professional participated for the first time in enacting a national copyright law, which led to unprecedented flourishing of library activities and copyright studies. The promulgation of another legal framework,'Government Information Disclosure Regulations' further advanced the research on related issues and pushed forward government information services in public libraries in the same way. A new landmark for library legislation in recent years is the promulgation of'Guidelines for Land Utilization for Public Library Construction' and 'Public Library Construction Standards', while the framing of 'Rules of Professional Ethics for Librarians in China(On trial)' and the 'Library Service Manifesto' give indication that a framework of self-disciplinary measures of library professionals is established.展开更多
