This study examines translatological dictionaries from the perspective of text linguistics with a discussion of the close relationship between translatological dictionary studies and text linguistics. This is done to promote translatological dictionary studies and further the development of translation studies. The study demonstrates the textual and extra-textual constraints on the research and compilation of translatological dictionaries by discussing how seven criteria of textuality can be integrated into translatological dictionary studies. The study discusses the following three topics: (1) an understanding of the translatological dictionary and its research methodologies; (2) theoretical basis and significance of the translatological dictionary as text; and (3) the integration of the seven criteria of textuality into translatological dictionary studies.
A new Schiff base complex of [UO2L(C2H5OH)(H2O)3]NO3 (HL=4-(2-hydroxy-naphthalen-1-ylmethyleneamino)-antipyrin) composition has been synthesized and characterized by elemental
analysis, IR, UV and molar conductance. The thermodecomposition kinetics of the complex was investigated under non-isothermal
conditions. TG and DTG curves indicate that the complex decomposes in five steps. The kinetics of the first step was calculated
by a combination of Achar differential and Coats-Redfern integral methods. The kinetic equation was determined.
The interaction of a flavonoid molecule (puerarin) with bovine serum albumin (BSA) was characterized by isothermal titration
calorimetry (ITC), optical spectroscopic technique, and molecular modeling method under physiological conditions. The binding
parameters for the reaction were calculated according to ITC experiments at different temperatures. The thermodynamic parameters,
negative enthalpy changes (ΔH), and positive entropy (ΔS) indicated that the binding processes were entropically driven. The alterations of protein secondary structure in the presence
of puerarin in aqueous solution were estimated by the evidences from FT-IR and CD spectroscopy with reductions of α-helices.
On the basis of fluorescence resonance energy transfer (FRET) between excited tryptophan in BSA and BSA bound puerarin, the
critical transfer distance and mean distance between tryptophan in BSA and puerarin were estimated.
In this study, the thermal analysis of the ω nanophase transformation from a quenched metastable β Ti–12Mo alloy composition
(mass%) was investigated by electrical resistivity and dilatometry measurements. The activation energy was observed to be
121 ± 20 kJ mol−1 (from resistivity measurements) and 114 ± 12 kJ mol−1 (from dilatometry measurements) during the early stage of the transformation process. The kinetic of the ω nanophase transformation
was modelized by using the classical Johnson–Mehl–Avrami (JMA) theory and a modified Avrami (MA) analysis. An Avrami exponent
close to 1.5 was found at the early stage of the transformation suggesting a pure growth mechanism from pre-existing nucleation
sites. Nevertheless, it was observed a decrease of the Avrami exponent to 0.5 at higher transformed fraction demonstrating
a dimension loss in the growth mechanism due to the existence of the high misfit strain at the interface β/ω.
Two new solid binuclear complexes of the compositions [(UO2)2(HL)3]NO3, and [Th2(HL)3(NO3)2](NO3)3 (H2L=o-vanillylidene anthranilic acid) have been synthesized and characterized by elemental analyses, DTA-TG, IR spectra, UV spectra and molar conductance. Possible structures of the two complexes have been proposed.
Sorption of thorium (IV) on goethite was investigated as a function of contact time, pH, ionic strength, anions, solid-to-liquid
ratio (m/V) and Th(IV) concentration using batch technique. The results showed that the sorption of Th(IV) was strong pH-dependence,
and increased from ~10 to ~100% over the pH range of 2.0–4.0, and then kept a constant level in the higher pH range. The sorption
of Th(IV) increased with increasing m/V and independent of ionic strength. It was clear that phosphate and FA significantly enhanced Th(IV) sorption on goethite.
The sorption and desorption isotherms were investigated at pH 2.90 ± 0.05 and analyzed with Freundlich and Langmuir models,
respectively. Compared to Langmuir model, Freundlich model could fit the experimental data better, according to the high relative
The exposure dose status on radioisotope production and application in China has been assessed in the paper. The average annual occupational exposure dose received by workers in the radioisotope production is about one tenth of the annual dose limit in normal situation. It is less than one twentieth for workers in the radioisotope applications. However, the annual collective dose for the latter is higher than the former by one oder of magnitude due to the larger number of workers in the application field. Although the output of radioisotopes increased doubly in 1980's as compared with 1970's, the increase on the annual collective dose was not obvious. For exposure to the public,131I for example, the collective dose in the radioisotope production decreased by one to two orders of magnitude and the releasing factor reduced by two orders of magnitude. Therefore, the exposure dose received by workers in radioisotope production and application is lower in normal situation. However, the facts worth paying attention to are that there were many events and accidents which happened in the radioisotope applications, especially at the irradiation facilities. The probability of fatal accident was as high as 10–3 per irradiator year. In order to improve the radiation safety situation, it is imperative to conduct the safety assessment for irradiation facilities, to enhance management of the radioactive wastes and spent sources and to establish the experience feedback system.
Two new solid complexes, [ThL(NO3)2](NO3)2, [UO2L(NO3)]NO3 (L=o-vanillin-p-phenylenediamine) have been synthesized and characterized by elemental analyses, DTA-TG, IR spectra, UV spectra and molar conductance. Possible structures of the two complexes are proposed.
The isothermal crystallization and subsequent melting behavior of one propylene homopolymer and three propylene-1-decene copolymers
with different comonomer contents prepared by metallocene catalyst were studied using differential scanning calorimetry (DSC).
It is found that the Avrami exponent of the propylene copolymers decreases gradually with the increase of comonomer content,
from 3.0 for the propylene homopolymer to 1.4 for the copolymer with 7.83 mol% 1-decene units. Higher comonomer content also
weakens the dependence of crystallization rate constant and crystallization halftime on temperature. Double melting peaks,
which correspond to α and γ crystal phases, respectively, are observed for all copolymers under isothermal crystallization.
The result shows that higher crystallization temperature is favorable to the segregation of α and γ crystal phases, resulting
in higher proportion of γ crystal phase.
A critical thermodynamic analysis of differential thermal calorimetry is reported herein to gain further insight into the
phenomena leading to the reported differences between kinetic parameters extracted from isothermal DSC methods and those from
dynamic DSC methods. The sources have been identified for the variations observed in the total heat of reaction as a function
of the heating rate in dynamic DSC experiments. The analysis clearly indicates that these variations are, in fact, to be anticipated.
The relationships necessary for extracting kinetic data from both isothermal and dynamic experiments are derived rigorously
by resorting to classical thermodynamics.
