We investigated the effects of Sn addition on the microstructural characteristics and mechanical properties of an extruded Mg-Bi binary alloy by comparing Mg-5 Bi(B5)and Mg-5 Bi-4 Sn(BT54).Both the extruded alloys exhibit a partially recrystallized grain structure with a strong extrusion fiber texture and numerous Mg3Bi2 ***,the addition of Sn significantly decreases the average grain size of the extruded alloy from 123.9 to 75.2μ*** Sn solute atoms inhibit the activity of dislocation slip,which reduces the internal strain energy accumulated in the dynamically recrystallized(DRXed)grains during ***,this reduced strain energy leads to the decrease in the DRXed grain size owing to weakened grain growth during natural *** extruded BT54 alloy exhibits higher tensile strength and ductility than the extruded B5 *** improvement in the strength by the Sn addition is attributed to the combined effects of grain refinement,Sn solute atoms,and increased dislocation *** formation of{10-11}and{10-11}-{10-12}twins during tension is suppressed by the grain refinement,thereby improving the tensile elongation considerably.

Nonylphenol in bivalves and sediments in the northeast coast of China

引用

Journal of Environmental Sciences 2010年第11期22卷 1735-1740页

作者： Juan Wang Won-joon Shim un-hynk Yim Narayanan Kannan Donghao Li Key Laboratory of Nature Resources of Changbai Mountain and Functional Molecular Ministry of Education of China Yanbian University Yanji 133002 China. Oil and POPs Research Group Korea Ocean Research and Development Institute Geoje-shi 656-834 Korea

To understand nonylphenol （NP） contamination in the northeast coastal environment in China, NP was determined in 19 sediment and 20 bivalve samples collected during November 2005. NP was identified in all sediment samples in the range of 8.8 to 1.0 × 10^3 ng/g dw （dry weight）, with an average of 0.12 × 10^3 ng/g dw. Most of the bivalve samples （oysters and mussels） contained detectable amounts of NP that ranged from ND （not detected） to 7.6 × 10^3 ng/g dw, with an average value of 0.79 × 10^3 ng/g dw. These results indicated that NP is ubiquitous in sediments and bivalves from the northeast coast of China, and are even present in bivalves sold as seafood. Serious contamination with NP was recorded off the coast of Bohai Strait and in semi-enclosed coastal environment such as Jiaozhou Bay and Liaodong Bay. Possible environmental and human health implications were understood in this study.

Transmural dispersion of repolarization：a complementary index for cardiac inhomogeneity

We read the article written by Nuis, et al. The authors investigated the effects of transcatheter aortic valve implantation （TAVI） on corrected QT dispersion （cQTD） in severe aortic stenosis patients. They concluded that, 40% of patients had defective cQTD recovery at six months after the procedure and this was associated with increased late mortality risk. We would like to contribute to the study from a different methodological perspective.
