The photodissociation dynamics of 1,2-bromochloroethane ($C_2H_4BrCl$) was investigated near 234 nm. A two-dimensional photofragment ion-imaging technique coupled with a [2+1] resonance-enhanced multiphoton ionization scheme was utilized to obtain speed and angular distributions of the nascent Br($^2P_{3/2}$) and Br${\ast}($^2P_{1/2}$) atoms. The total translational energy distributions for the Br and Br${\ast}$ channels were well characterized by Gaussian functions with average translational energies of 100 and 84 kJ/mol, respectively. The recoil anisotropies for the Br and Br${\ast}$ channels were measured to be ${\beta}$ = 0.49 ${\pm}$ 0.05 for Br and 1.55 ${\pm}$ 0.05 for Br${\ast}$. The relative quantum yield for Br${\ast}$ was found to be ${\Phi}_{Br{\ast}}$ = 0.33 ${\pm}$ 0.03. The probability of nonadiabatic transition between A' states was estimated to be 0.46. The relevant nonadiabatic dynamics is discussed in terms of interaction between potential energy surfaces in Cs symmetry.
DETERMINANTS OF PORT SELECTION

This paper explores the main factors adopted when shippers and shipping companies select their import/export and transshipment ports. In the present study, 38 port selection indices were chosen from the previous research and field interviews. The scores of the 38 items were collected by questionnaire survey to the three major maritime/port market players: shipper, liners and container terminal operators. In order to analyze the different priorities imposed on the port selection factors by the three market players, an one-way ANOVA technique has been employed. As a consequence, this research shows the different recognitions about port service attributes among service suppliers and demanders. In addition, the 38 items have been categorized into seven key factors through an exploratory factor analysis. An one-way ANOVA was employed again to analyze the perspective differences for the port selection factors among the market players. The results show that there exit significant differences among the players assessing the importance of the following port choice factors: hinterland and terminal basic condition; shipping liners’ operations and terminal operations.
Container port selection factors

This study explores the main factors considered when shippers and container shipping lines select their import/export and transshipment ports. In the present study, 38 container port selection indices were chosen from the previous research and field interviews. The scores of the 38 items were collected via survey to the three major maritime/port market players: shoppers, shipping lines, and container terminal operators. In order to analyze the different priorities imposed on the port selection factors by the three market players, the ANOVA method has been employed. The empirical test shows the different perceptions about port selection attributes among service suppliers and demanders. In addition, the 38 items have been categorized into seven key factors through an exploratory factor analysis. The ANOVA technique was emloyed again to analyze the perspective differences for the port selection factors among the market players. The results show that there are significant differences among the players assessing the importance of the three port choice factors: liners and terminal operators give more weight to ‘hinterland and terminal basic conditions’ than shippers; terminal operators do not take ‘line operation’ as seriously as carriers and shippers; the factor of ‘terminal operation’ is more significantly considered by liners and terminal operators than by shoppers.

<B>Abstract</B><P>Due to the lack of an effective prophylactic intervention and diagnosis, human liver fluke <I>Clonorchis sinensis</I> continues to afflict a large human population, causing a chronic inflammatory bile duct disease. With an aim to identify target antigens for sensitive serodiagnosis, adenylate kinase 3 of <I>C. sinensis</I> (CsAK3) was successfully expressed in soluble form in <I>Escherichia coli</I> by fusion to an RNA-interacting domain derived from human Lys-tRNA synthetase and purified by Ni<SUP>2+</SUP>-affinity chromatography. Anti-CsAK3 serum was raised by immunization of mice, and Western blotting confirmed that CsAK3 was expressed in adult-stage <I>C. sinensis</I>. Histochemical analysis showed that CsAK3 was localized to the subtegumental tissue of <I>C. sinensis</I> and was excreted into the bile duct of the host. When tested against sera from various parasite-infected patients by enzyme-linked immunosorbent assay, the recombinant CsAK3 elicited a specific response to <I>C. sinensis</I>-infected sera. The results suggest that CsAK3, either alone or in combination with other antigens, could be used for improving the clinical diagnosis of clonorchiasis.</P>
