1巴赫曼束(心耳间横肌束)及其动脉血供的多层螺旋CT成像对心房间传导异常和心律失常的提示显示文摘目的利用64层CT成像回顾性研究健康人和病人的巴赫曼束(BB)的解剖及其血供。方法本研究依从HIPAA法案并得到了机构审查委员会的批准可免除知情同意书。回顾317例病人(对照组164例,病人组153例)的临床病史、心电图(ECG)和64层CT冠状动脉成像影像。病人组中,房颤(AF)或房间传导阻滞(IAB)68例(P波持续时间≥120ms),严重冠状动脉疾病(CAD)46例[发出窦房结(SAN)动脉的冠状动脉狭窄程度≥70%],严重CAD同时有心电图异常39例(AF或IAB)。对BB的长度、F.Saremi S.Channual S.Krishnan S.V.Gurudevan J.Narula A.Abolhoda 邱建星 2008国际医学放射学杂志2008,31,5:8
2Growth,structural,optical,thermal and dielectric properties of a novel semi-organic nonlinear optical crystal:Dichloro-diglycine zinc Ⅱ显示文摘Dichloro-diglycine zinc II(DCDGZ II),a semi-organic nonlinear optical material has been synthesized and single crystals were grown from the aqueous solution up to dimensions 20×10×3 mm3.The title compound,DCDGZ II(C4H10Cl2N2O4Zn H2O) crystallizes into monoclinic structure with the space group of C2/c.The unit-cell parameters were found to be a=14.4191(7),b=6.9180(2),c=12.9452(6) and Z=4.In the crystal structure,DCDGZ II layer is building up alternatingly with layers of water in which the zinc ions lie on a twofold axis.Theoretical calculations for polarizability,which are useful for device fabrication were made using Clausius–Mosotti equation and Penn analysis and the results were compared.Fourier transform infrared(FTIR) spectroscopic studies were performed for the identification of the different functional groups presented in the compound.The UV–vis–NIR absorption spectrum reveals that the lower UV cut-off wavelength is 240 nm.The optical band gap of the crystal was estimated as 2.2 eV.The surface morphology,thermal behaviour,dielectric properties have been studied using SEM,TG/DTA and LCR HITESTER analyzer.The nonlinear optical property of the crystal was also confirmed using Kurtz powder technique.B.Uma Rajnikant K.Sakthi Murugesan S.Krishnan B.Milton Boaz 2014Progress in Natural Science:Materials International2014,24,4:0
3印度核能发展规划的经验显示文摘印度关于核能的长远规划分为三个阶段,以通过闭路燃料循环和再循环最终达到利用中浓铀和钍资源的目的。印度核能规划的第一阶段是发展加压式重水堆(PHWRs),进展非常良好。印度核能规划的基础主要基于两点:①印度核能开发和燃料循环的特色;②印度国内的工业基础。S.KRISHNAN 朱常桂(摘译) 2007国外核动力2007,28,2:0
