Electrorheological properties of poly[N,N0-(2-amino-5-carboxybutyl-1,3- phenylenedimethylene)-2,20-diamino-4,40-bithiazole]

Song Xinrong,Song Kunyang,Ding Sha,Chen Yaping,Lin Yuanbin 한국공업화학회 2013 Journal of Industrial and Engineering Chemistry Vol.19 No.2

Poly[N,N0-(2-amino-5-carboxybutyl-1,3-phenylenedimethylene)-2,20-diamino-4,40-bithiazole] was synthesized and characterized with Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Anhydrous electrorheological (ER) fluids were prepared using the polymer particles as disperse phase and bromodiphenylmethane as a disperse medium. Rheological measurements were carried out via a rotational rheometer to investigate the effects of electric field strength and the polymer particle content on the ER properties. Results indicate that suspensions of the polymer particles containing amino and carboxybutyl groups in bromodiphenylmethane exhibit a substantial ER effect.

QTL Analysis of Floral Traits of Rice (Oryza Sativa L.) under Well-Watered and Drought Stress Conditions

Song Ping Hu,Ying Zhou,Lin Zhang,Xu Dong Zhu,Zheng Gong Wang,Lin Li,Li Jun Luo,Qing Ming Zhou 한국유전학회 2009 Genes & Genomics Vol.31 No.2

Three floral traits, spikelet number per panicle (SNP), percentage of single exserted stigma (PSES) and dual exserted stigma (PDES) of a RI population with 185 lines under water stress and non-stress conditions for two years were investigated in a drought tolerance screening facility. ANOVA results showed high significance between years, lines, and water stress treatments, together with interactions among them in pairs. High phenotypic correlation was found between PSES and PDES (r=0.5424***). Based on a linkage map of 203 SSR markers, when under well-watered condition, six QTLs (qSNP-3b, qSNP-4, qSNP-11 qSNP-2, qSNP-5 and qSNP-9) were detected for SNP. Half of them had significant Q×E interactions. Three QTLs (qPSES-1, qPSES-2, qPSES-5) were found to influence PSES, including one locus (qPSES-2) having Q×E interaction. And three QTLs (qPDES-2, qPDES-5 and qPDES-8) were also detected to influence PDES. qPDES-5 was found to have Q×E interaction. The contribution rate of a single QTL varied from 0.80% to 8.83% for additive effect, and 1.86% to 15.25% for Q×E interactions. Under drought stress, six QTLs (qSNP-3a, qSNP-4, qSNP-7a, qSNP-7b, qSNP-8 and qSNP-9) were associated with SNP, including qSNP-3a and qSNP-4 with Q×E interaction. Three QTLs (qPSES-1, qPSES-10 and qPSES-12) were located on rice chromosome 1, 10 and 12 for PSES. Four QTLs (qPDES-1a, qPDES-1b, qPDES-4 and qPDES-9) were detected for PDES, including qPDES-9 with Q×E interaction. The additive effect of single QTL can only explain 1.16% to 5.84% of total variance while Q×E interaction of four loci can explain 4.25% to 11.54% of total variance for each locus. There were one to nine pairs of epistatic QTLs influencing SNP and stigma exsertion. The contribution rates of additive and epistatic effects seemed to be in a low magnitude for most cases (0.76%~9.92%) while a few QTLs or QTL pairs explained more than 10% of total variance. Some main effect QTL and epistasis were commonly detected among PSES and PDES, explaining the high positive correlation between them. Few QTLs were detected under both water stress and non-stress conditions, indicating that drought had severe impact on the genetic behaviors of both spikelet number and stigma exsertion.

The Textual Research on Qidiaoshi School

( Song Li-lin ) 성균관대학교 유교문화연구소 2011 儒敎文化硏究(中文版) Vol.0 No.15

孔子之后, “儒分爲八”, “漆雕氏之儒”爲其中之一。由于史料有限, 對漆雕氏之儒的硏究不多且存在諸多問題。通過綜合排比史料, 可知漆雕氏之儒的開創者乃孔子弟子漆雕開。漆雕開, 是魯人而非蔡人, 少孔子11 歲而非小孔子41 歲, 爲孔子早年弟子非晩期弟子。《漢志》著錄《漆雕子》, 所注“漆雕啓后”之“后”字當爲衍文, 不過這部作品可以視爲漆雕氏之儒的學派集體著作, 而學者將《呂氏春秋》中的《忠廉》、《當務》等十幾篇文獻視爲該派作品, 多屬臆測, 難以信從。《儒行》篇當是漆雕氏之儒所“傳述”的孔子言論, 而非漆雕氏之儒的“著作”。學者將北宮黝、宓子贱等劃爲漆雕氏之儒的做法是不可取的。漆雕氏之儒的思想特征, 可歸納爲:(1)傳習《尙書》;(2)不樂仕;(3)人性有善有惡說;(4)尙勇。學界流行的將漆雕氏之儒視爲“任侠派”的觀点同樣是不成立的。 After Confucius, the Confucian was divided into eight schools. One of them was Qidiaoshi school (漆雕氏之儒). As historical material is limited, the research of the Qidiaoshi school is sparse and there are many problems. Through the comprehensive historical material, we know the Master of the Qidiaoshi school is Qidiaokai (漆雕开). He was born in the state of Lu (鲁国) but not the state of Cai (蔡国). He was 11 years younger than Confucius, rather than 41 years. So he was one of the students of Confucius in the early stage. The book of Qidiaozi (漆雕子) could be regarded as collective works of the Qidiaoshi school. But I do not think it is credible that some literature in Lvshichunqiu (吕氏春秋), such as Zhonglian (忠廉) and Dangwu (当务) etc, is looked as the works of the Qidiaoshi school. The literature of Ruxing (儒行) should be the saying and thought of Confucius recorded and narrated by the Qidiaoshi school. It is inadvisable that put Beigongyou (北宫黝) and Fuzijian (宓子贱) as members of the Qidiaoshi school. The popular view that Qidiaoshi school belongs to the knight-errant school is not untenable.

<▼1><P>A “three birds one stone” strategy for preparing 1D N-doped porous carbon nanotubes embedded with Co@CoOx nanoparticles results in the unprecedentedly high-rate Zn–air batteries.</P></▼1><▼2><P>In this work, we demonstrate a “three birds one stone” strategy for preparing 1D N-doped porous carbon nanotubes embedded with core–shell Co@CoOx nanoparticles (Co@CoOx/NCNTs) from bimetallic ZnO@Zn/Co-ZIF nanowires. The ZnO nanowires played three roles: (i) ZnO acted as a template for 1D metal–organic framework (MOF) growth, (ii) <I>in situ</I> evaporation of Zn during pyrolysis prevented the aggregation of the carbon framework and benefited the formation of hierarchical pores, and (iii) the excess oxygen species released from ZnO <I>in situ</I> reacted with metallic cobalt nanoparticles during pyrolysis, leading to the configuration of a Co@CoOx core–shell structure. The as-prepared 1D Co@CoOx/NCNTs exhibited excellent oxygen reduction reaction performance, including a high kinetic current (4.6 times better compared to 20 wt% Pt/C at 0.7 V), a low Tafel slope of 80 mV dec<SUP>−1</SUP>, outstanding stability, and strong tolerance to CH3OH crossover. The assembled Zn–air batteries with Co@CoOx/NCNTs yielded high open-circuit voltage (1.52 V), superior stability (over 100 h of operation), and unprecedented rate performance that ranged from 1 to 500 mA cm<SUP>−2</SUP>, while existing batteries have never achieved a galvanostatic discharge current density larger than 300 mA cm<SUP>−2</SUP>. Such exceptional rate capability was ascribed to the formation of a uniform interconnected nanotube network, facilitated electron transport, and an enlarged electrochemically accessible surface area in the unique 1D porous tubular structure.</P></▼2>

Song-lin Gang,Mi-Kum Kim,Chang-Je Kim 한국항해항만학회 2009 한국항해항만학회지 Vol.33 No.2

Shipwaves can have harmful effects on ships working on the sea. in a harbour or navigational channel and caused beach erosion, seawall destruction. This study aims to investigate describe the characteristics of the wave pattern generated by an individual model ship tested at different velocities and hull forms for a given water depth and to investigate the variations at a given distance from the sailing line under the same conditions. As a result, the angles a's by model ship tests are smaller than those by real ship ones. Wave heights decreases with an increasing the mid-ship cross sectional area As. The maximum wave height and period increase rapidly in the sabcritical speed, and beyond the critical speed the height and period decrease with increasing depth Froude number. And the period keeps constant with the distance from the sailing line.

Lin Hui,신은석,전은정,백영준,Scot Garg,김태현,손창배,최병주,Liu Kun,Song Lin Yuan,Wang Zhi,Jiang Hao,Shi Zhentao,Tang Qiang 연세대학교의과대학 2020 Yonsei medical journal Vol.61 No.12

Purpose: Dissection after plain balloon angioplasty is required to achieve adequate luminal area; however, it is associated with ahigh risk of vascular events. This study aimed to examine the relationship between non-flow limiting coronary dissections andsubsequent lumen loss and long-term clinical outcomes following successful drug-coated balloon (DCB) treatment of de novocoronary lesions. Materials and Methods: A total of 227 patients with good distal flow (Thrombolysis in Myocardial Infarction flow grade 3) followingDCB treatment were retrospectively enrolled and stratified according to the presence or absence of a non-flow limiting dissection. The primary endpoint was late lumen loss (LLL) at 6-month angiography, and the secondary endpoint was target vesselfailure (TVF, a composite of cardiac death, target vessel myocardial infarction, target vessel revascularization, and target vesselthrombosis). Results: The cohort consisted of 95 patients with and 132 patients without a dissection. There were no between-group differencesin LLL (90.8%) returning for angiography at 6 months (0.05±0.19 mm in non-dissection and 0.05±0.30 mm in dissection group, p=0.886) or in TVF (6.8% in non-dissection and 8.4% in dissection group, p=0.799) at a median follow-up of 3.4 years. In a multivariateanalysis, the presence of dissection and its severity were not associated with LLL or TVF. Almost dissections (93.9%) were completelyhealed, and there was no newly developed dissection at 6-month angiography. Conclusion: The presence of a dissection following successful DCB treatment of a de novo coronary lesion may not be associatedwith an increased risk of LLL or TVF (Impact of Drug-coated Balloon Treatment in de Novo Coronary Lesion; NCT04619277).

Fault Location Scheme for Over-Zone Feeding Operation Condition on High-Speed Railway

Lin Guo-song,Quan Wei,Tong Xiao-yang 대한전기학회 2022 Journal of Electrical Engineering & Technology Vol.17 No.2

Cross-coupling autotransformer (AT) feeding system is applied on high-speed electrifi ed railways in China. According to operation requirement, ‘over-zone feeding operation condition’ exists. When fault occurs on this operation condition, the fault location system should adjust its original scheme to adapt. We analyzed the shortcoming in traditional fault location of this feeding mode. Analysis indicates that when fault occurs in the non-over-zone section, fault location can be well done by existing principle and when fault occurs in the over-zone section, a new fault location scheme must be proposed. Based on the analysis of circuit networks of over-zone section in this feeding mode, the feeder current ratio of up line and down line in sectioning post (SP) is derived when fault occurs in section from SP to AT post 2 (ATP2) and the port impedance at ATP2 is derived when fault occurs in section from ATP2 to substation 2 (SS2). A reasonable fault location scheme was proposed for over-zone section based on feeder current ratio method of up line and down line and port impedance method in this paper. The simulation results based on Matlab/Simulink showed that when fault occurs on over-zone section the fault position can be located accurately according to this novel fault location scheme
