Selected AbstractsAn improved region,time,length algorithm applied to the 1999 Chi-Chi, Taiwan earthquakeGEOPHYSICAL JOURNAL INTERNATIONAL, Issue 3 2006Chien-Chih Chen SUMMARY By means of the region,time,length (RTL) algorithm, which is widely used for investigating the precursory seismicity changes in China, Italy, Japan, Russia and Turkey, we examine the precursory seismic activity occurred prior to the 1999, Mw= 7.6, Chi-Chi earthquake around its epicentre. Based on our calculation of the RTL values, the epicentral area has been found to strongly exhibit the signature of anomalous activity, associated with the seismic quiescence and activation, before the main shock. Also proposed in this study is a helpful method for determining two important parameters used in the RTL analysis, the characteristic time and distance. Such method will largely reduce the ambiguity in the original RTL algorithm. [source] Is ECG-guidance a helpful method to correctly position a central venous catheter during prehospital emergency care?ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 7 2005J. S. David Background:, Insertion of a central venous catheter (CVC) in an emergency situation is challenging and may be potentially associated with more complications. Because CVC positioning by ECG-guidance may help to decrease the frequency of a malpositioned catheter, we decided to prospectively evaluate the usefulness of positioning a CVC by ECG-guidance during prehospital emergency care. Methods:, Prospective observational study during which all patients requiring CVC placement during prehospital care were included. We compared two periods of 1 year during which CVCs were inserted without and then with the help of ECG-guidance. Results:, Eighty successive patients were included. We observed a significant reduction of incorrectly positioned CVCs with ECG-guidance (13% vs. 38%, P < 0.05) and a decreased number of chest X-rays needed to verify the position of the CVC (40 vs. 54, P < 0.05). Conclusion:, ECG-guidance is a safe and feasible technique which significantly improved the rate of CVCs correctly positioned during prehospital emergency care. [source] Prospecting for (Campaign) GoldAMERICAN JOURNAL OF POLITICAL SCIENCE, Issue 2 2007Wendy K. Tam Cho Campaigns and political parties are faced with the immensely important practical challenge of financing their efforts. Raising money is instrumental to all other aims. In recent years, this task has been complicated by the need to enlist ever greater numbers of contributors to raise ever larger sums of money. At the same time, fundraising burdens are eased a bit because contributors flock together. That is, campaign contributing is a spatially dependent phenomenon, associated with affluence and the presence of networks. Accordingly, geospatial tools provide a helpful method for understanding and predicting where contributions can be most successfully mined. [source] LEAD ISOTOPE ANALYSIS OF TANG SANCAI POTTERY GLAZES FROM GONGYI KILN, HENAN PROVINCE AND HUANGBAO KILN, SHAANXI PROVINCEARCHAEOMETRY, Issue 4 2010J. F. CUI Through the use of MC,ICP,MS, this study analyses the lead isotope ratios of 19 Tang Sancai pottery glazes unearthed from the Gongyi and Huangbao kiln sites. According to their different lead isotope ratios, the two kilns can be grouped separately. The research also suggests that the Gongyi and Huangbao kilns are independent production centres of Tang Sancai in the Tang Dynasty. The data from the Huangbao kiln indicates that the lead in the glazes originates from the Northern China geochemical province, while the data from Gongyi kiln suggests its source as the Yangtze geochemical province. Furthermore, the results obtained for the Tang Sancai pottery indicate that the lead sources for glaze making of these two kilns were very consistent, which suggests that lead isotope analysis could be a helpful method to identify the kilns producing Tang Sancai artefacts.
