对近几年风力发电系统维修方面的措施进行综述、分析、讨论和总结。风力发电系统寿命周期费用的绝大部分归因于运行和维修活动，这对于近海风电场是很重要的。这些费用的很大一部分源于在系统规划和概念设计的早期阶段所做的可靠性和可维修性决策的结果。维修作为一种支持功能对于获得和维持竞争优势具有重要作用，因此风电场业主、运营者和原始设备制造商都应重视风力发电系统的维修，需建立风力发电系统正确的维修策略，以保证安全、可持续和具竞争力的能源供应。

The Behavior of Multi-Story Buildings Seismically Isolated System Hybrid Isolation (Friction, Rubber and with the Addition of Rotational Friction Dampers)

引用

Open Journal of Earthquake Research 2015年第1期4卷 1-13页

作者： Alaa Barmo imad H. Mualla Hala T. Hasan Department of Structural Engineering Higher Institute of Seismic Research and Studies University of Damascus Damascus Syria DAMPTECH Ltd Technical University of Denmark Lyngby Denmark

Increasing buildings’ resistance to earthquake forces is not always a desirable solution especially for the building contents that are irreplaceable or simply more valuable than the actual primary structure (e.g. museums, data storage Centre’s, etc.). Base isolation and seismic dampers can be employed to minimize inter-story drifts and floor accelerations via specially designed isolation and dampers system at the structural base, or at higher levels of the superstructure. In this research, we’ll examine the response of buildings isolated using isolation system hybrid consisting of Lead-Rubber Bearings (LRB), Flat Sliding Bearings (FSB), with the addition of Rotation Fiction Damper (FD) at the base, then compare the results with buildings that have traditional foundation, in terms of the (period, displacement and distribution shear force and height of the building). It conducts TIME HISTORY seismic analysis for some varying height buildings (eight, twelve, sixteen, and twenty stories), with help of SAP2000 using an earthquake acceleration-time history for (el- Centro). The results show that the use of insulation system Hybrid has had a significant impact on improving the performance of origin in terms of reducing displacements and base shear with in-creasing height of the building, but has had a negative impact on the drift, which leads to an in-crease in drift with the increased flexibility of the building.

Incidence and prevalence of hepatitis B and hepatitis C viruses in hemodialysis patients in Lebanon

AIM: To determine the incidence and the prevalence of hepatitis B and C viral infections in patients on hemodialysis(HD) across ***: We reviewed the data registry at the Lebanese Ministry of Public Health where records of monthly hepatitis B surface antigen(HBs Ag) and hepatitis C virus(HCV) serology are reported from 60 affiliated HD centers across Lebanon. All patients who were on HD or who started HD between October 2010 and July 2012 were included in the study. Patients from seven HD centers were excluded due to inadequate and incomplete results reporting. During the selected period, HBs Ag and HCV serology were available for 3769 patients from 53 HD centers distributed at all Lebanese governorates. The prevalence was calculated by dividing the number of patients with positive HBs Ag or HCV serology to the total number of patients. The Incidence was calculated by dividing the number of newly acquired infection to number of patients-years(p-y). Incidence rates at different governorates were compared to each other using two tailed Z test and a P value of ely. The comparison of prevalence according to geographic distribution could not be done accurately due to the frequent shift of patients between dialysis centers at different governorates. The incidence rate was 0.27 per 100 p-y for HBV and 0.37 per 100 p-y for HCV. There was no significant difference concerning the incidence of HBV between HD centers at different governorates(all P values > 0.1), but this difference was highly significant concerning the incidence rates of HCV which occurred predominantly in the southern centers(1.47 per 100 p-y) with a P value of 0.00068 and 0.00374 when compared to Mount Lebanon(0.21 per 100 p-y) and
