This study focuses on the notions of explicitation and implicitation in translation and aims to provide empirical evidence for operational asymmetry (Klaudy 2001). Bi-directional (SL=L1→TL=L2 and SL=L2→TL=L1) comparisons show that when explicitation takes place in the L1→L2 direction, implicitation can be observed in the L2→L1 direction. This phenomenon is referred to as symmetric explicitation. It may also happen, however, that when explicitation is carried out in the L1→L2 direction, no implicitation occurs in the L2→L1 direction. This phenomenon is referred to as asymmetric explicitation. It would be logical to suppose that all cases of language-specific explicitation in the L1→L2 direction are symmetrical (i.e., matched by implicitation in the L2→L1 direction), but this does not seem to be the case. The present paper reports on the findings of an empirical study designed to investigate the validity of the asymmetry hypothesis in the translation of reporting verbs in literary texts translated from English into Hungarian and from Hungarian into English. Using the method of two-way qualitative translation analysis, the study demonstrates that translators tend to prefer the more explicit forms to the more implicit ones in both directions and often fail to perform implicitation. The study may thus provide further evidence for the assumption that semantic explicitation is in fact a universal translation strategy.

Abstract  

The thermal decomposition of Cu2L2Cl4, Cu2L2Cl2, Cu2L2Br2 and Co2L2Cl4 complexes (L=3,5-dimethyl-1-thiocarboxamidepyrazole) is described. The influence of the central ion to ligand mole ratio on the course of complex formation is examined in reaction of L with copper(II) chloride. In Cu(II):L mole ratio of 1:1, in methanolic solution the reaction yields to yellow-green Cu2L2Cl4 crystals. In the filtrate a thermodynamically more stable orange Cu2L2Cl2 copper(I) complex is forming. With a Cu(II):L mole ratio of 1:2 only the latter compound is obtained. The composition and the structure of the compounds have been determined on the basis of customary methods. On the basis of FTIR spectrum of the intermediate which is forming during the thermal decomposition of Cu2L2Cl2 a decomposition mechanism is proposed.

Abstract  

The purpose of this work was to indirect label IgG with fac-[188Re(CO)3(H2O)3]+ and to check the radiochemical behavior of the labeled product. The compound of (bis(2-pyridylmethyl)-amino)-acetic acid (L2H) was synthesized and labeled with fac-[188Re(CO)3(H2O)3]+. The labeling yield of 188Re(CO)3–L2H was more than 90%. The effects of protein concentration, reaction time, pH and reaction temperature of labeling of IgG with 188Re(CO)3–L2H were investigated. The conjugation conditions were optimized. The labeled product was analyzed by size exclusion HPLC and TLC. The stability of 188Re(CO)3–L2H–IgG in vitro was high. The results of this study may be useful for [188Re(CO)3(H2O)3]+ labeling of protein for radioimmunotherapy.

N,N,N',N',N'',N''-Hexaethyl-2,2′,2''-(nitrilotrisethyleneoxy-2-benzyloxy)tris(acetamide) (L3) has been prepared and characterized by using IR, 1H NMR and positive-ion FAB mass spectra. The extraction of Th4+ and UO2 2+ with N,N,N',N',N'',N''-hexaethyl-2,2',2''- (nitrilo-trisethyleneoxy)tris(acetamide) (L1), N,N,N',N',N'',N''-hexaisopropyl-2,2',2''-(nitrilotrisethyleneoxy)tris(acetamide) (L2), and L3 was studied at 20±1 °C as a function of diluent, concentration of free extractant in organic phase and concentration of picrate in aqueous phase. It was found that the extracting powers of L1 and L2 for Th4+ are almost identical. The extracting power of L2 for UO22+ was slightly higher than that of L1. The difference in terminal groups (ethyl or isopropyl) of the extractants (L1 and L2) with same backbone has a little effect on the extracting power for both Th4+ and UO22+. The extracting powers of L3 for both Th4+ and UO22+ were larger than those of L1 and L2. The extractants (L1 and L3) having the same terminal group (ethyl) with different backbones have obviously different extracting powers for Th4+ or UO22+. The extracting powers of all three extractants L1, L2, and L3 for Th4+ were larger than those for UO22+. The compositions of extracted species in organic phase were predominantly ThL(Pic)3NO3 and UO2L(Pic)NO3, respectively (L denotes L1, L2 and L3).

Abstract  

Two open-chain crown ethers 2,2'-(ethylenedioxy)bis[(8-quinolyloxymethyl)benzene], (L1), and 2,2'-(ethylenedioxy)bis[(8-quinaldyloxymethyl)benzene], (L2) have been prepared and characterized by using elemental analysis, IR spectra, 1H NMR spectra and positive-ion FAB mass spectra. The extraction of UO2 2+ and Th4+ by both open-chain crown ethers, L1 and L2 in chloroform as a diluent was studied at 25 °C. Extraction distribution ratios (D) of UO2 2+ and Th4+ were investigated as a function of pH, lithium picrate concentration, and extractant concentration. Based on the expertimental results, it was found that 1 : 1 complexes were formed involving either UO2 2+ or Th4+ with L1, and Th4+ with L2. The extractability of L1 for Th4+ is significantly higher than that for UO2 2+, the extractabilities of L1 and L2 for Th4+ being almost identical. L1 and L2 used here are not feasible for industry because of their relatively low extractabilities for Th4+ at pH<2.0 and for UO2 2+ at the extraction conditions used in this work.
