Background: Patients on hemodialysis are at high risk of adverse cardiac events after coronary artery bypass grafting (CABG). The aim of this study is to know whether CABG with complete revascularization and similar graft selection can provide equivalent long-term benefits for patients on and not on hemodialysis. Methods: Between 2004 and 2018, 746 patients underwent isolated CABG, of which 106 were on hemodialysis. Propensity matching on baseline characteristics, graft types and on/off-pump CABG was performed to compare clinical outcomes between patients on (n = 102) and not on (n = 102) hemodialysis. Results: Complete revascularization was achieved in all patients. The mean follow-up was 112.5 ± 46.6 months. Off-pump rates (hemodialysis vs non-hemodialysis, 93/102 vs 94/102, p > 0.999) and graft selections (distal anastomoses: 3.7 ± 1.4 vs 3.8 ± 1.5, p = 0.377, ITA grafts: 1.4 ± 0.6 vs 1.5 ± 0.6, p = 0.560, arterial grafts: 1.9 ± 0.9 vs 2.0 ± 0.8, p = 0.658, vein grafts: 0.69 ± 0.63 vs 0.65 ± 0.70, p = 0.513) were well balanced between the groups. Hospital mortality was higher in patients on hemodialysis than in those not on hemodialysis (5/102 vs 1/102, p = 0.212). The Kaplan-Meier analysis revealed that cardiac death (without non-cardiac causes) was significantly more common in patients on hemodialysis than in those not on hemodialysis (p = 0.018). However, there were no significant differences in deaths due to ischemic heart disease (p = 0.327), repeated revascularization (p = 0.542), myocardial infarction (p = 0.783), and heart failure requiring admission (p = 0.371). Conclusion: CABG with complete revascularization and similar graft selection provides equivalent long-term benefits with regard to the prevention of adverse cardiac events due to ischemic heart disease in patients on and not on hemodialysis.

为得到隔雨伞对染污交流空心套管大雨闪络特性的影响规律,通过模拟试验进行了研究。试验采用5m长、不同伞形的表面脏污瓷空心套管,模拟了大雨条件下这些套管的闪络,获得了套管的闪络特性。同时对套管在淋雨状态下,施加电压后电弧起始、发展、直至闪络或耐受的全过程,以及同步的泄漏电流典型特征进行了分析。结果表明:在爬电距离相近条件下,装有4片隔雨伞和8片隔雨伞的套管最大淋雨耐受电压分别比无隔雨伞时提高了72.7%和127.3%;隔雨伞的存在影响了套管湿润状态、分隔雨帘的形成并阻挡了电弧的串接,使泄漏电流从0增大至最大值或至闪络的时间减小;隔雨伞能够大幅度提高套管在大雨情况下的耐受电压。以上情况也说明,在选择套管或支柱的户外绝缘时,爬电距离不能作为唯一的标准。

OPTIMAL MATCHING DESIGN METHOD OF THE WELLS TURBINE WITH THE AIR CHAMBER IN AN OSCILLATING AIR FLOW

引用

Journal of Hydrodynamics 1991年第2期3卷 107-114页

作者： Yu, Zhi maeda, Hisaaki Guangzhou Inst of Energy Conversion Guangzhou China

Matching design of the Wells turbine with the air chamber is one of the key problems in the design of an OWC (Oscillating water column) wave energy conversion system. Based on the assumptions of linear response of the OWC to the wave force and quasi-steady air flow through the turbine, in this paper, the matching design of the Wells turbine in an oscillating air flow is transformed into the problem of determining optimal amplitude of incident angle (αmopt) and the matching design with the performance of air chamber and (αmopt), which is only a point matching design problem. Two matching design methods, based on the match of flow rate and the average pressure drop and the match of flow rate and average power output respectively, are presented. The error between the two methods is analysed. As a design example, the method has been applied to designing the Wells turbine operating in China's first onshore wave power station built at the outlet of the Pearl River, South China Sea.

Vibrational dynamics of the CN stretching mode of [Ru(CN)_6]^(4-) in D_2O studied by nonlinear infrared spectroscopy

引用

Science China(Physics,Mechanics & Astronomy) 2010年第6期53卷 1013-1019页

作者： Jumpei TAYAMA motohiro BANNO Kaoru OHTA Keisuke TOMINAGA Graduate School of Science Kobe University Molecular Photoscience Research Center Kobe University PRESTO JST4-1-8 Honcho KawaguchiSaitamaJapan 332-0012Japan

We have studied vibrational dynamics of the T1u mode of the CN stretching mode of [Ru(CN)6 ]4- in D2O by infrared(IR) nonlinear spectroscopy such as an IR three-pulse photon echo experiment and polarization-sensitive IR pump-probe spectroscopy. The isotropic component of the pump-probe signal shows a bi-exponential decay with time constants of 0.8 ps and 20.8 ps. The fast and slow components correspond to the rapid equilibration between the T1u mode and the Raman active modes of the CN stretching mode and the vibrational population relaxation from the v=1 state of the T1u mode,respectively. Anisotropy of the pump-probe signal decays with a time constant of 3.1 ps,which is due to the time evolution of the superposition states of the triply degenerate T1u modes. Three pulse photon echo measurements showed that the time correlation function of the frequency fluctuation decays bi-exponentially with time constants of 80 fs and 1.4 ps. These time constants depend only on the solute and are independent of the solvent,whereas the amplitudes depend on both the solute and solvent.
