Reshaping the New Paradigm of Classroom Culture Construction in Colleges and Universities

The classroom is an important place for“three guarantees”education.Classroom culture refers to a group culture with both teachers and students as the main body,the classroom space as the carrier,and spiritual connotation as the core.The creation of classroom culture with school characteristics,characteristics of the times,and Chinese characteristics can reflect the aesthetic perspective and value orientation of the school,which has far-reaching significance for the growth of students and their future development.This paper takes the construction of classroom culture in colleges and universities as the research subject,obtains real data,and conducts variable analysis through questionnaire survey and structured interview,with the aim of enriching the educational function of the classroom.It involves how the classroom culture pays attention to the current life,needs,and desires of college and university students,along with the problems and functions that should be improved in the traditional construction.This paper also discusses and reshapes the new paradigm of classroom culture construction in colleges and universities based on the combination of student growth,subject areas,school culture,and advanced technology.

新标09CrCuSb耐酸钢的耐50%H_(2)SO_(4)腐蚀性能

通过电化学测试和全浸腐蚀试验,研究了不同温度(25,50,60,70℃)条件下新标09CrCuSb耐酸钢在50%H_(2)SO_(4)溶液中的腐蚀行为。结果表明:随着温度从25℃升至70℃,新标09CrCuSb钢的腐蚀速率整体呈现增大趋势,在70℃时,腐蚀速率达到最高,为2.70 g/(m^(2)·h),这与随温度升高,腐蚀产物中具有保护性作用的Fe_(3)O_(4)含量减少,无保护作用的FeSO_(4)·H_(2)O含量增加以及锈层中微孔变化有关。另外,由于新标调整了09CrCuSb钢中Cu、Mo、Sn、Sb、W等元素的含量,与旧标09CrCuSb钢相比,阳极维钝电流密度J维钝降低,同等温度条件下,新标09CrCuSb钢的耐蚀性得到较大改善。

Sequence analysis of VP4 genes of wild type and culture adapted human rotavirus G1P[8]strains

Objective:To conduct a comparative analysis of the VP4 gene sequences of Indian wild type (06361,0613158,061060 and 0715880) and cell culture adapted(06361-CA,0613158-CA.061060- CA and 0715880-CA) G1P[8]rotavirus strains.Methods:Full-length VP4 genes of each of the four wild type G1P[8]rotavirus strains and their cell culture adapted counterparts displaying consistent cytopathic effect were subjected to RT-PCR amplification and nucleotide sequencing. Results:All four cell culture adapted G1P[8]rotavirus strains showed nucleotide and amino acid substitutions in the VP4 gene as compared to their wild type strains.The number of substitutions however,varied from 1-64 and 1-13 respectively.The substitutions were distributed in both VP5* and VP8* subunits of VP4 gene respectively of permeabilizalion and hemagglutinaling activity. The presence of unique amino acid substitutions was identified in two of the four wild type(V377G. S387N in 061060 and 1644L in 0715880) and all four cell culture adapted(A46V in 0613158-CA. T60R in 06361-CA,L237V.G389V and Q480H in 061060-CA and S615G and T625P in 0715880-CA) strains for the first time in the VP4 gene of P[8]specificity.Amino acid substitutions generated increase in the hydrophilicity in the cell culture adapted rotavirus strains as compared to their corresponding wild type strains.Conclusions:Amino acid substitutions detected in the VP4 genes of G1P[8]rotavirus strains from this study together with those from other studies highlight occurrence of only strain and/or host specific substitutions during cell culture adaptation. Further evaluation of such substitutions for their role in attenuation,immunogenicity and conformation is needed for the development of newer rolavirus vaccines.

Effects of CuSO_4 and Uniconazole on Mature Embryo Culture in Japonica Rice

In order to establish the system of high frequency plant regeneration for japonica rice mature embryos, the effects of different concentrations of CuSO4 and uniconazole on in vitro culture of mature embryos were studied using three rice cultivars of Kongyu 131, Longjing 24, and Dongnong 425 as test materials. The results showed that callus induction and differentiation of japonica rice mature embryos were apparently improved on the medium with 10-15 μmol·L-1 CuSO4 and 0.50-1.00 mg·L-1 uniconazole. Induction and differentiation rates of different genotype rice mature embryos displayed different sensitivities to CuSO4 and uniconazole. For the callus induction frequency of three varieties, the optimal concentration of CuSO4 was 15.0 mol·L-1. When the concentration of CuSO4 was 15 μmol·L-1, the plantlet differentiation rates of Kongyu 131 and Dongnong 425 got to the highest, while the concentration of CuSO4 was 10 μmol·L-1 for Longjing 24. For the callus induction and plantlet differentiation rates of Kongyu 131 and Dongnong 425, the ideal concentration of uniconazole was 0.50 mg·L-1 and for Longjing 24 was 1.00 mg·L-1.
