Research on the Mechanism of Overseas Promotion and Translation by Chinese Publishing Houses from the Perspective of Sponsor

Translation activities are usually influenced by various factors. Lefevere mentioned in “Translation, Rewriting, and the Manipulation of Literary Reputation” that translation activities are influenced by ideology, aesthetics, and sponsors, among which sponsors have the greatest influence on the translation activities. Sponsors are further divided into ideological sponsors, economic sponsors, and social status sponsors. Through the study from the perspective of sponsors, it is discovered that the government plays an important role in the publicity and translation activities of publishing houses in China, providing economic and ideological sponsorship for their publicity and translation activities

Nanoparticle Injection Technology For Remediating Leaks of CO2 Storage Formation

In the last several decades, hundreds of projects have successfully transported the CO2 into the reservoir underground. After the injection underground, the CO2 gas is potentially move upward or sideways due to the unbalanced pressure in the subsurface. CO2 may leak from the interface of different materials, such as the interface of steel casing and cement, the interface between steel casing and cement plug, the voids inside the cement, the crack of steel casing, the crack of cement, and the interface of rock and cement. This dissertation presents different methodologies to analyze the potential reasons of leakages and further find a solution on how to repair the leakages. Due to the harsh underground environment, especially high concentration of CO2 and chloride, distressing and fracturing occurs in the hardened cement which could cause the severe cracks and further leading to the leakages of storage CO2 . The chloride-induced corrosion and carbonation effect are the two main effects to deteriorate the mechanical properties of the oil well cement. The modeling works are adopted for simulating the chloride-induced corrosion and carbonation effect. After the reason analysis, the experimental program is conducted to inject nanoparticles into the oil well cement. Several beneficial nanoparticles can be injected into the cement not only to repair wellbore leakages but also to extract harmful ions for the cement simultaneously. Injection is done using the electro-migration method. In the last step, a simulation work is presented for the effectiveness of nanoparticles injected into the cementitious material. The general framework of numerical modeling is developed to describe the proposed electrochemical injection technology. A model for nanoparticle injection is developed first, in which an externally applied current on the system is characterized. Based on this general framework, the chloride removal is included, which means this process can not only repair the leakage and cracks, but also remove the harmful ions from the well cement.</p

Objective Air Pollution and the Subjective Well-being of Chinese Residents

In this study, we constructed a new database to investigate the complex relationship between hazy weather, heightened air pollution concerns due to elevated PM 2.5 levels, and residents’ well-being in China. Our study concludes that the results of the baseline regression showing that PM2.5 significantly increases the well-being of the population is at odds with common sense, which is attributed to potential endogeneity issues, including reverse causation and omitted variables. For this purpose, first, we used the instrumental variables method to exclude the endogeneity problem and obtained a causal relation between objective air pollution and well-being, that is, objective air pollution significantly and negatively affects residents’ well-being. Second, we also considered the effect of individual differences and verified the mechanistic pathways by which objective air pollution affects well-being through residents’ subjective air pollution. Specifically, we found that in the air quality evaluation process, “pessimistic” residents have a lower level of well-being, and “optimistic” residents have a higher level of well-being. Finally, we verified that the level of household income can weaken the negative impact of objective air pollution on residents’ well-being and has a positive moderating effect. By integrating macro and micro-level data through innovative technology, our research provides policy recommendations for effective pollution management and improved overall well-being in China.publishedVersio

Theoretical Modeling on Chemical Composition and Mechanical Properties of Well Cement under Carbonation Reactions

This paper presents theoretical models of the phase transformation and the change of mechanical properties of oil well cement due to underground carbonation reactions. Application of oil well cement has become common practice in CO2 underground storage formations. However, the CO2 stored underground may leak through damaged well cement, and it can cause carbonation reactions which may significantly decrease the mechanical properties of well cement. Extensive research has been conducted by using experimental methods in laboratories to characterize the carbonation reactions of cement underground. However, no theoretical formulations have been developed considering the mechanical properties change due to the carbonation effect. In this paper, the CO2 profile was predicted first by the error function solution of a 1D CO2 diffusion equation and further the carbonation reaction rate was calculated. The phase transformation of well cement due to carbonation were then analyzed by using a stoichiometric model. After that, the changes of mechanical properties of well cement were modeled using a two-phase generalized self-consistent model at different scales. Specifically, the decrease of the elastic modulus of well cement during the carbonation process was used as an example application of the model. Finally, the modeling result was validated with published experimental results. &nbsp;</p

Fabrication and characterization of La2Zr2O7 films on different buffer architectures for YBa2Cu3O7−δ coated conductors by RF magnetron sputtering

Abstract La2Zr2O7 (LZO) films were grown on different buffer architectures by radio frequency magnetron sputtering for the large-scale application of YBa2Cu3O7−x (YBCO)-coated conductors. The three different buffer architectures were cerium oxide (CeO2), yttria-stabilized zirconia (YSZ)/CeO2, and CeO2/YSZ/CeO2. The microstructure and surface morphology of the LZO film were studied by X-ray diffraction, optical microscopy, field emission scanning electron microscopy, and atomic force microscopy. The LZO films prepared on the CeO2, YSZ/CeO2, and CeO2/YSZ/CeO2 buffer architectures were preferentially c-axis-oriented and highly textured. The in-plane texture of LZO film on CeO2 single-buffer architecture was ∆ φ = 5.5° and the out-of-plane texture was ∆ ω = 3.4°. All the LZO films had very smooth surfaces, but LZO films grown on YSZ/CeO2 and CeO2/YSZ/CeO2 buffer architectures had cracks. The highly textured LZO film grown on CeO2-seed buffered NiW tape was suitable for the epitaxial growth of YBCO film with high currents.</jats:p

Dependencies of microstructure and stress on the thickness of GdBa2Cu3O7 − δ thin films fabricated by RF sputtering

Abstract GdBa2Cu3O7 − δ (GdBCO) films with different thicknesses from 200 to 2,100 nm are deposited on CeO2/yttria-stabilized zirconia (YSZ)/CeO2-buffered Ni-W substrates by radio-frequency magnetron sputtering. Both the X-ray diffraction and scanning electron microscopy analyses reveal that the a-axis grains appear at the upper layers of the films when the thickness reaches to 1,030 nm. The X-ray photoelectron spectroscopy measurement implies that the oxygen content is insufficient in upper layers beyond 1,030 nm for a thicker film. The Williamson-Hall method is used to observe the variation of film stress with increasing thickness of our films. It is found that the highest residual stresses exist in the thinnest film, while the lowest residual stresses exist in the 1,030-nm-thick film. With further increasing film thickness, the film residual stresses increase again. However, the critical current (I c) of the GdBCO film first shows a nearly linear increase and then shows a more slowly enhancing to a final stagnation as film thickness increases from 200 to 1,030 nm and then to 2,100 nm. It is concluded that the roughness and stress are not the main reasons which cause the slow or no increase in I c. Also, the thickness dependency of GdBa2Cu3O7 − δ films on the I c is attributed to three main factors: a-axis grains, gaps between a-axis grains, and oxygen deficiency for the upper layers of a thick film.</jats:p

Identification of alternative splicing events related to fatty liver formation in duck using full-length transcripts

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is one of most common diseases in the world. Recently, alternative splicing (AS) has been reported to play a key role in NAFLD processes in mammals. Ducks can quickly form fatty liver similar to human NAFLD after overfeeding and restore to normal liver in a short time, suggesting that ducks are an excellent model to unravel molecular mechanisms of lipid metabolism for NAFLD. However, how alternative splicing events (ASEs) affect the fatty liver process in ducks is still unclear.RESULTS: Here we identify 126,277 unique transcripts in liver tissue from an overfed duck (77,237 total transcripts) and its sibling control (69,618 total transcripts). We combined these full-length transcripts with Illumina RNA-seq data from five pairs of overfed ducks and control individuals. Full-length transcript sequencing provided us with structural information of transcripts and Illumina RNA-seq data reveals the expressional profile of each transcript. We found, among these unique transcripts, 30,618 were lncRNAs and 1,744 transcripts including 155 lncRNAs and 1,589 coding transcripts showed significantly differential expression in liver tissues between overfed ducks and control individuals. We also detected 27,317 ASEs and 142 of them showed significant relative abundance changes in ducks under different feeding conditions. Full-length transcript profiles together with Illumina RNA-seq data demonstrated that 10 genes involving in lipid metabolism had ASEs with significantly differential abundance in normally fed (control) and overfed ducks. Among these genes, protein products of five genes (CYP4F22, BTN, GSTA2, ADH5, and DHRS2 genes) were changed by ASEs.CONCLUSIONS: This study presents an example of how to identify ASEs related to important biological processes, such as fatty liver formation, using full-length transcripts alongside Illumina RNA-seq data. Based on these data, we screened out ASEs of lipid-metabolism related genes which might respond to overfeeding. Our future ability to explore the function of genes showing AS differences between overfed ducks and their sibling controls, using genetic manipulations and co-evolutionary studies, will certainly extend our knowledge of genes related to the non-pathogenic fatty liver process.</p

Explorative case control study on the associations of serum vitamin D3, folic acid and vitamin B12 levels on Kawasaki disease and coronary artery lesions

BackgroundKawasaki Disease (KD) is a pediatric vasculitic disorder characterized by systemic small vasculitis, notably coronary arteritis, with unclear pathogenesis. This explorative case-control study investigated the association between folic acid (FA), vitamin D3 (VD3), and vitamin B12 (VB12) levels and the different types of Kawasaki Disease, as well as the incidence of coronary artery lesions (CALs).MethodsIn this explorative case control study, 365 KD children admitted to our hospital from January 1, 2022 to June 30, 2023 were included as the KD group. Simultaneously, 365 healthy children who received physical examination during the same period were included as the control group. The KD group was divided into typical KD group and incomplete KD group (IKD group), CALs group and non-CALS group, and IVIG sensitive group and IVIG resistant group. The children with CALs were divided into small tumor group, medium tumor group and large tumor group. Serum levels of FA, VB12, and VD3 were compared across all groups.ResultsSerum levels of FA and VD3 were significantly decreased in both the KD and CALs groups (p &lt; 0.05), and both factors were identified as independent risk factors for KD and CALs. Similarly, reduced serum VD3 levels were observed in the IKD and IVIG-resistant groups (p &lt; 0.05), with VD3 also being an independent risk factor for both IKD and IVIG resistance. Additionally, lower serum FA levels were noted in the group with large aneurysms (p &lt; 0.05), establishing FA as an independent risk factor for aneurysm size.ConclusionSerum levels of folic FA and vitamin VD3 were significantly reduced in children with KD. Furthermore, these reductions were more pronounced in children with IKD and CALs. This pattern suggests that lower FA and VD3 levels may increase the risk of more severe coronary lesions in KD patients. Therefore, monitoring these biomarkers could provide valuable insights for early clinical diagnosis and intervention
