Teaching Research on Integrating Ideological and Political Elements into Business English Reading Courses

In the current situation of economic globalization and communalization with a shared future for mankind,it is crucial to cultivate outstanding composite talents who possess morality,literacy,patriotism,business knowledge,good cross-cultural communication skills,and teamwork spirit.This requires the Business English major to increase the reform of course ideology.This article will propose several innovative paths for the ideological and political education of Business English Reading courses based on the necessity of conducting ideological and political education in Business English majors and working together with colleagues to study.

THE ZERO LIMIT OF THERMAL DIFFUSIVITY FOR THE 2D DENSITY-DEPENDENT BOUSSINESQ EQUATIONS

This paper is concerned with the asymptotic behavior of solutions to the initial boundary problem of the two-dimensional density-dependent Boussinesq equations.It is shown that the solutions of the Boussinesq equations converge to those of zero thermal diffusivity Boussinesq equations as the thermal diffusivity tends to zero,and the convergence rate is established.In addition,we prove that the boundary-layer thickness is of the valueδ(k)=k^(α)with anyα∈(0,1/4)for a small diffusivity coefficient k>0,and we also find a function to describe the properties of the boundary layer.

New Nanoplatform based on Upconversion Nanoparticles for Sensitive Detection of Acute promyelocytic Leukemia

Acute promyelocytic leukemia(APL)is a special leukemia accounting for above 10%of adult acute myeloid leukemia.The t(15;17)(q22;q21)is a specific chromosome reciprocal translocation of APL,resulting in the generation of a fusion gene between a retinoic acid receptor alpha(RARα)and promyelocytic leukemia(PML)at the molecular level.Many research demonstrate that PML/RARa fusion gene can be regarded as

Extraction of hydrogen chloride by a coupled reaction-solvent extraction process

A coupled 反应溶剂抽取过程被用来把 HCl 从模仿的蒸馏器浪费移开。各种各样的提炼之物和 diluents 的抽取表演被比较，在各种各样的 diluents 的 N235 (第三级的胺的混合物) 的明显的盐基度是坚定的。最好的结果作为提炼之物用 N235 和 isoamyl 酒精被获得并且稀释分别地。从联合抽取的 HCl 的收益与这个抽取系统是 75% 。为在两个的 HCl 的移动的机制直接、联合的抽取被调查。为联合抽取， R 3 NHCl 离子对建筑群涉及 HCl 移动。为直接抽取，机制在 HCl 的高集中包含了氢契约的形成。

Core pluripotency factors promote glycolysis of human embryonic stem cells by activating GLUT1 enhancer

Human embryonic stem cells (hESCs) depend on glycolysis for energy and substrates for biosynthesis. To understand the mechanisms governing the metabolism of hESCs, we investigated the transcriptional regulation of glucose transporter 1 (GLUT1, SLC2A1), a key glycolytic gene to maintain pluripotency. By combining the genome-wide data of bin ding sites of the core pluripotency factors (SOX2, OCT4, NANOG, denoted SON), chromosomal interaction and histone modification in hESCs, we identified a potential enhancer of the GLUT1 gene in hESCs, de noted GLUT1 enhancer (GE) element GE interacts with the promoter of GLUT1, and the deletion of GE significantly reduces the expression of GLUT1, glucose uptake and glycolysis of hESCs, confirming that GE is an enhancer of GLUT1 in hESCs. In addition, the mutation of SON binding motifs within GE reduced the expression of GLUT1 as well as the interaction between GE and GLUT1 promoter, indicating that the binding of SON to GE is important for its activity. Therefore, SON promotes glucose uptake and glycolysis in hESCs by inducing GLUT1 expression through directly activating the enhancer of GLUT1.

Continuous cropping of alfalfa (Medicago sativa L.) reduces bacterial diversity and simplifies cooccurrence networks in aeolian sandy soil

Alfalfa is a perennial herbaceous forage legume that is remarkably and negatively affected by monocropping.However,the contribution of the changes in bacterial communities to soil sickness in alfalfa have not been elucidated.Therefore,we investigated bacterial community structures in response to monocropped alfalfa along the chronosequence.Continuous cropping remarkably reduced bacterial alpha diversity and altered community structures,and soil pH,total P and available P were strongly associated with the changes of bacterial diversity and community structures.Intriguingly,10 years of monocropped alfalfa might be a demarcation point separating soil bacterial community structures into two obvious groups that containing soil samples collected in less and more than 10 years.The relative abundances of copiotrophic bacteria of Actinobacteria and Gammaproteobacteria significantly increased with the extension of continuous cropping years,while the oligotrophic bacteria of Armatimonadetes,Chloroflexi,Firmicutes and Gemmatimonadetes showed the opposite changing patterns.Among those altered phyla,Actinobacteria,Chloroflexi,Alphaproteobacteria and Acidobacteria were the most important bacteria which contributed 50.86%of the community variations. Additionally, the relative abundances of nitrogen fixation bacteria ofBradyrhizobium and Mesorhizobium obviously increased with continuous cropping years, while theabundances of Arthrobacter, Bacillus, Burkholderiaceae and Microbacterium with potential functionsof solubilizing phosphorus and potassium remarkably decreased after long-term continuouscropping. Furthermore, bacterial cooccurrence patterns were significantly influenced by continuouscropping years, with long-term monocropped alfalfa simplifying the complexity of the cooccurrencenetworks. These findings enhanced our understandings and provided references for forecasting howsoil bacterial communities responds to monocropped alfalfa.
