Su, Yan-lei,Liu, Hui-zhou 한국화학공학회 2003 Korean Journal of Chemical Engineering Vol.20 No.2

The effect of temperature on naphthalene solubilization in aqueous PEO-PPO-PEO block copolymer solutions has been investigated. Increasing temperature would enhance the apparent solubility of naphthalene in aqueous PEO-PPO_PEO block copolymer solutions. The pseudo-phase model was employed to calculate thermodynamic parameters for naphthalene solubilization in aqueous PEO-PPO_PEO block copolymer solutions.

Background: Telomerase reverse transcriptase (TERT) and cleft lip and palate trans-membrane 1 like (CLPTM1L) genes located on chromosome 5p15.33 are known to influence the susceptibility to various cancers. Here, we examined the association of TERT and CLPTM1L single nucleotide polymorphisms (SNPs) with hepatocellular carcinoma (HCC). Materials and Methods: Genotyping of TERT SNP rs2736098 and CLPTM1L SNP rs401681 was performed using TaqMan allelic discrimination assays in a case-control study of 201 HCC cases and 210 controls in a Chinese male population. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression analyses. Results: Both the rs2736098 T allele of TERT and the rs401681 T allele of CLPTM1L were associated with a significantly increased risk of HCC (adjusted odds ratio [OR]=1.605, 95% confidence interval [CI]=1.164-2.213; adjusted OR=1.399, 95%CI=1.002-1.955, respectively). Individuals carrying both TERT and CLPTM1L risk genotypes had an even higher risk of HCC (adjusted OR=4.420, 95%CI= 2.319-8.425). The TERT rs2736098 T allele was also significantly associated with the level of the HCC clinical indicator alpha-fetoprotein (P=0.026). Conclusions: Our results show that genetic variants of TERT and CLPTM1L may contribute to HCC susceptibility in Chinese males.

A method is described for ideally reconstructing the profile from a surface profiling measurement containing a reasonable amount of null measurement data. The proposed method can conjecture lost information and rectify irregular data that result due to bad measuring environments. signal transmission noise. or instrument-induced errors. The method adopts the concept 0/ computer graphics and consists of several processing steps. First, a search for valid data in the neighborhood of the null data is performed. The valid data are then grouped and their contours are extracted. By analyzing these contours, a bounding box can be obtained and the general distribution of the entire area encompassing the valid and null data is determined. Finally, em ideal surface model is overlaid onto the measurement results based on the bounding box, generating a complete reconstruction of the calculations. A surface-profiling task on a liquid crystal display photo spacer is used to verify the proposed method. The results are compared to those obtained through the use of a scanning electron microscope to demonstrate the accuracy of the proposed method.

EXPERIMENTAL STUDY OF PARTICULATE EMISSION CHARACTERISTICS FROM A GASOLINE DIRECT INJECTION ENGINE DURING STARTING PROCESS

Yan Su,Fangxi Xie,Wei Hong,Xiaoping Li,Tingting Hu 한국자동차공학회 2019 International journal of automotive technology Vol.20 No.2

The engine starting process presents high particulate emissions in exhaust. This study gives a systematic investigation on particulate emission characteristics, including particulate matter (PM) mass, soluble organic fraction (SOF) mass, C10-C26 n-Alkanes and particle-bound polycyclic aromatic hydrocarbons (PAHs), that have been emitted from a gasoline direct injection (GDI) engine measured by Gas chromatography–mass spectrometry during starting period. The results show that particulate emissions under the warm coolant start condition decline dramatically compared with the cold start condition. 90 % of particulate number (PN) emitted during the cold and warm start periods generally are nucleation-mode particles. Over 50 % PM mass and PAHs emissions are emitted in the first 0−13 s stage. SOF mass accounts more than 60 % in PM mass emissions, especially under the warm coolant start condition. Some C23-C26 n-Alkanes are detected under the cold start condition which demonstrates that partial particulate composition directly comes from lubricant. The concentration of the two ring PAHs is the lowest among PAHs while the four to six ring PAHs are higher under the cold start operation. The toxicity of PAHs which is evaluated by Benzo(a)pyrene equivalent toxicity (BEQ) value of the total PAHs emissions shows a decline of 66.83 % under the warm start condition.

A subset of patients of amyotrophic lateral sclerosis (ALS) present with mutation of Cu/Zn superoxide dismutase 1 (SOD1), and such mutants caused an ALSlike disorder when expressed in rodents. These findings implicated SOD1 in ALS pathogenesis and made the transgenic animals a widely used ALS model. However, previous studies of these animals have focused largely on motor neuron damage. We report herein that the spinal cords of mice expressing a human SOD1 mutant (hSOD1-G93A), besides showing typical destruction of motor neurons and axons, exhibit significant damage in the sensory system, including Wallerian-like degeneration in axons of dorsal root and dorsal funiculus, and mitochondrial damage in dorsal root ganglia neurons. Thus, hSOD1-G93A mutation causes both motor and sensory neuropathies, and as such the disease developed in the transgenic mice very closely resembles human ALS.

The Contemporary Value of Xunzi`s Political Ethics Thought for the Social Administration

( Yan Jun Dai ) , ( Lin Su ) 한국윤리학회 2014 倫理硏究 Vol.95 No.1

Xunzi`s political ethical thought, including gentleman personality, people-oriented, prospering etiquettes and respecting law and so on, still has a relational meaning for the modern social political moral construction. Gentleman personality comes with an obligation to improve the leading officials` morality; the idea of people-oriented has a vital significance for establishing“ put people first“ thought throughout society and insisting the mass line; This statecraft that focuses both on ritual and law has a very important revelation for improving the foundation for anti-corruption and a clean government. Xunzi`s political ethical thought provides the value for our country`s conducting a harmonious and efficient social administration through the three dimensions mentioned above.

Les idees et la traduction

( Su Wei Yan ) 한국통역번역학회 2005 FORUM Vol.3 No.1

Languages such as Chinese and French are so different from one another as regard to linguistic structure that the translation can never be done from a purely linguistic dimension. In such context, what should the starting point be for a translator doing his work? In other words, what`s the target of a translating operation? It is nothing but the idea, which results from understanding and cognitive interpretation of original expression. Every translation means persona interpretation of translator. The idea, to a certain extent, emerged from understanding in non-verbal form. The same idea not only gave birth to author`s expression but also generates the expression by which the translator reformulates, in his turn, what he understood in the original text.

Probabilistic Load Flow Calculation Method of Containing Wind Farm Considering Grid Configuration Uncertainties

Hongsheng Su,Yan Yan 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.8

Current probabilistic power flow calculation methods mostly consider the uncertainties of loads and the random failures of generators without thinking about the changing of the grids structure. Hence, this paper proposes a new probabilistic power flow calculation method comprehensively considering the influences of the uncertainties of wind farms, loads, generators, and grids structure on power flow calculation. The linear relationships are deduced between the nodes injection power and the branch active power as the circuits being at failures, and the cumulative probability distribution of each branches power flow is calculated by using semi-invariant and Gram-Charlier series expansion, and such that the complicated convolution operation is avoided. Combining compensation method and the conditional probability theory to deal with network structure changes of random factors, the paper establishes a probability flow calculation model comprehensively considering diverse factors such as random outputting power of the wind farms, random changes of the loads, and random failures of the generators, and the random variation of the grid structures and so on, the probability distribution function and probability density function of each branch can be quickly obtained by the model. Through the analysis on IEEE 14-node system, the uncertainty of grid structure has a remarkable effect on the probability distribution of the quantity to be solved. Hence, applying the proposed method can provide planners with more accurate and comprehensive information.
