The equilibrium configuration of a solid strange star in the final inspiral phase with another compact object is generally discussed,and the starquake-related issue is revisited,for a special purpose to understand the precursor emission of binary compact star merger events(e.g.,that of GrB211211A).As the binary system inspirals inward due to gravitational wave radiation,the ellipticity of the solid strangeon star increases due to the growing tidal field of its compact *** energy is hence accumulated during the inspiral stage which might trigger a starquake before the merger when the energy exceeds a critical *** energy released during such starquakes is calculated and compared to the precursor observation of GrB211211 *** result shows that the energy might be insufficient for binary strangeon-star case unless the entire solid strangeon star shatters,and hence favors a black hole-strangeon star scenario for *** timescale of the precursor as well as the frequency of the observed quasi-periodic-oscillation have also been discussed in the starquake model.

Nonylphenol in bivalves and sediments in the northeast coast of China

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.
