Yong-Jun Deng,Jun Wei,Yang Wang,Bin Zhang 한국원자력학회 2019 Nuclear Engineering and Technology Vol.51 No.6
The fuel rod performance has great importance for the safety and economy of an operating reactor. Thefuel rod performance analysis code, which considers the thermal-mechanical response and irradiationeffects of fuel rod, is usually developed in order to predict fuel rod performance accurately. The FRIPAC(Fuel Rod Integral Performance Analysis Code) is such a fuel rod performance analysis code that has beendeveloped recently by China Nuclear Power Technology Research Institute Co. Ltd. The code aims at thecomputational simulation of the Pressurized Water Reactor fuel rod behavior for both steady-state andpower ramp condition. A brief overview of FRIPAC is presented including the computational frameworkand the main behavioral models. Validation of the code is also presented and it focuses on the fuel rodbehavior including fuel center temperature, fission gas release, rod internal pressure/internal void volume,cladding outer diameter and cladding corrosion thickness. The validation is based on experimentaldata from several international projects. The validation results indicate that FRIPAC is an accurate andreliable fuel rod performance analysis code because of the satisfactory comparison results between theexperimental measurements and the code predictions.

政權合法性針對的是統治能否得到被統治者認可的問題。統治者爲了獲得認可, 需要進行政權合法性建構。中國古代形成了一套政權合法性觀念, 大致可分爲來源合法性與治理合法性兩個方面。雖然古代也重視來源合法性, 推崇以和平穩定、優質高效的禅讓制實現政權交替, 但是, 古人眞正看重的乃是治理合法性。治理合法性是政權合法性的充要條件, 其核心是正德利用厚生, 而來源合法性只是輔助條件。 Politics in ancient China paid much attention to the legitimacy of the political power, which mainly referred to the approval of the people. The idea of the legitimacy of power contains two topics: the legitimacy of the source, and that of governance. Ancient Chinese stressed on the legitimacy of the source; they advocated the peaceful and effective non-hereditary imperial succession to ensure a steady transfer of power. However, what they really cared was the legitimacy of governance. The latter is the necessary and sufficient condition to the former. The core of the legitimacy of governance is to straighten the virtue, to facilitate the necessity, and to enrich the life. The legitimacy of the origin is but an auxiliary condition.

The plant Schisandra chinensis contains a phytoestrogens, a type of naturally occurring estrogens which have multiple functions in a number of biological processes. To investigate the correlation between phytoestrogens and epigenetic modification, especially the effect of phytoestrogens on DNA methylation, sexually healthy female mice were used as an animal model in the present study. Briefly, the total RNA and protein were isolated from the ovary of mice after 7-day oral administration of Schisandra chinensis extract (SCE), while distilled water was given to the animals in the control group. Real-time PCR, Western blotting, and enzyme activity assays were performed to examine the effect of the extract of S. chinensis on Dnmt1 transcription and activity. A promoter assay was further conducted in MCF cells (ER positive) to explore also the influence of SCE on Dnmt1 transcriptional activity. The results revealed that the mRNA and protein expression levels of mouse Dnmt1 were both significantly downregulated in the treated group. The transcription of Dnmt1 was suppressed by SCE and in the E2-added group also. Meanwhile the numbers of oocytes at different stages were increased in the treated group when compared by histological analyses with those in the control group. Taken together, the results indicated that, similarly to the action of estrogen, phytoestrogens affected Dnmt1 transcription in mammals, regulating the related gene expression and cell differentiation. The findings of our examination provided also basic data and understanding for the correlation between phytoestrogens and epigenetic modification.

LBH is a transcription factor as a candidate gene for CHD associated with partial trisomy 2p syndrome. To identify potential LBH-interacting partners, a yeast two-hybrid screen using LBH as a bait was performed with a human heart cDNA library. One of the clones identified encodes αB-crystallin. Co-immunoprecipitation and GST pull-down assays showed that LBH interacts with αB-crystallin, which is further confirmed by mammalian two-hybrid assays. Co-localization analysis showed that in COS-7 cells, αB-crystallin that is cytoplasmic alone, accumulates partialy in the nucleus when co-transfected with LBH. Transient transfection assays indicated that overexpression of LBH or αB-crystallin reduced the transcriptional activities of p53 and p21, respectively, Overexpression of both αB-crystallin and LBH together resulted in a stronger repression of the transcriptional activities of p21 and p53. These results showed that the interaction of LBH and αB-crystallin may inhibit synergistically the transcriptional regulation of p53 and p21. [BMB reports 2010; 43(6): 432-437]

In this study, we report the identification and characterization of a novel C2H2 zinc finger protein, ZNF552, from a human embryonic heart cDNA library. ZNF552 is composed of three exons and two introns and maps to chromosome 19q13.43. The cDNA of ZNF552 is 2.3 kb, encoding 407 amino acids with an amino-terminal KRAB domain and seven carboxyl-terminal C2H2 zinc finger motifs in the nucleus and cytoplasm. Northern blotting analysis indicated that a 2.3 kb transcript specific for ZNF552 was expressed in liver, lung, spleen, testis and kidney, especially with a higher level in the lung and testis in human adult tissues. Reporter gene assays showed that ZNF552 was a transcriptional repressor, and overexpression of ZNF552 in the COS-7 cells inhibited the transcriptional activities of AP-1 and SRE, which could be relieved through RNAi analysis. Deletion studies showed that the KRAB domain of ZNF552 may be involved in this inhibition. [BMB reports 2010; 43(3): 193-198]

Post-earthquake fire is a common disaster which causes serious safety issues to infrastructures. This study aims to investigate the residual loading capacities of circular concrete-filled steel tube (CFST) columns under post-earthquake fire experimentally and numerically. The experimental programme contains two loading steps - pre-damage cyclic loading at room temperature and transient state tests with constant compression loads. Three finite element models are developed and validated against the test results. Upon validation, a total of 48 numerical results were generated in the parametric study to investigate the effects of thickness and strengths of steel tube, axial compression ratio and damage degree on the fire resistance of circular CFST columns. Based on the analysis on experimental and numerical results, the loading mechanism of circular CFST columns is discussed. A design method is proposed for the prediction of fire resistance time under different seismic pre-damage and compression loads. The predictions by the new method is compared with the newly generated experimental and numerical results and is found to be accurate and consistent with the mean value close to the unity and a coefficient of variation around 1%.

The thermodynamic properties of small metallic superconducting grains are affected by fluctuations in the order parameter and the level statistics, especially in the critical region. Here, the static path approximation was applied to deal with the fluctuations and the thermodynamic contribution of quasiparticles, and random matrix theory was applied to deal with level statistics. The specific heats were calculated numerically in the cases of even and odd number of electrons and different spins.
Experimental investigation of the preferred Strouhal number used in self-resonating pulsed waterjet
Deng Li,Youping Chen,Yong Kang,Zu’an Wang,Xiaoliang Wang,Qi Fan,Miao Yuan 대한기계학회 2018 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.32 No.9
Self-resonating pulsed waterjet (SRPW) is superior to plain waterjet in many ways and is being employed in numerous applications. To further improve the performance of SRPW, the optimal value of the preferred Strouhal number (S d ), which is used to determine the chamber length of a self-resonating nozzle, was experimentally studied at inlet pressures of 10 MPa and 20 MPa. The axial pressure oscillation peak and amplitude were used to evaluate the performance of SRPW, in order to find the optimum S d value. Results show that S dvalue determines the self-resonance behavior of an organ-pipe nozzle and greatly affects the intensity of the axial pressure oscillation. Under the experimental conditions, the optimum S d values are 0.315 and 0.278 respectively, corresponding to inlet pressures of 10 MPa and 20 MPa. Compared with the default value of 0.3 obtained from air jet experiment, the optimum S d value at inlet pressure of 10 MPa is a little larger and oppositely a bit smaller at inlet pressure of 20 MPa. Thus, if the inlet pressure is not considered, S d value of 0.3 is reasonable for determining the chamber length of a self-resonating nozzle for generating effective SRPW.
