Intra-industry trade in agricultural products : the case of China
Jing, Wang; Leitão, Nuno Carlos; Faustino, Horácio C.This paper studies the extent and determinants of intra-industry trade (IIT) in agricultural products of China for the period 1997-2006. The IIT index shows that the level of IIT in agricultural products between China and its thirteen main trading partners is not high. Using a panel data analysis, the empirical results of determinants of IIT indicate that differences in per-capita income and geographical distan...

Solid phase extraction and spectrophotometric determination of mercury in tobac...
Yang,Weizhu; Hu,Qun; Ma,Jing; Wang,Liming; Yang,Guangyu; Xie,GangA highly sensitive, selective and rapid method for the determination of mercury based on the rapid reaction of mercury(II) with 5-(p-aminobenzylidene)-thiorhodanine (ABTR) and the solid phase extraction of the colored chelate with C18 disks has been developed. At pH 3.5 and in the presence of emulsifier-OP medium, ABTR reacts with mercury(II) to form a red chelate of a 1:2 (mercury to ABTR) molar ratio. This ch...
