This paper analyses the seismic performance of exterior beam-column joints strengthened with unconventional reinforcement detailing. The beam-column joint specimens were tested with reverse cyclic loading applied at the beam end. The samples were divided into two groups based on the joint reinforcement detailing. The first group (Group A) of three non-ductility specimens had joint detailing in accordance with the construction code of practice in India IS456-2000, and the second group (Group B) of three ductility specimens had joint reinforcement detailed as per IS13920-1993, with similar axial load cases as the first group. The experimental studies are proven with the analytical studies carried out by finite element models using ANSYS. The results show that the hysteresis simulation is satisfactory for both un-strengthened and ferrocement strengthened specimens. Furthermore, when ferrocement strengthening is employed, the strengthened beam-column joints exhibit better structural performance than the un-strengthened specimens of about 31.56% and 38.98 for DD-T1 and DD-T2 respectively. The analytical shear strength predictions were in line with the test results reported in the literature, thus adding confidence to the validity of the proposed models.

To the Editor： With great interest, we read the article ＇~Multibacillary Leprosy in a Child＂ by Wang eta/.Ill The authors have nicely shown the rare presentation in highly unsuspected clinical dermatological case. Authors also have emphasized the importance of early biopsy including Fite-Faraco stain to make a diagnosis of multibacillary leprosy that is important in patients with only atypical cutaneous manifestations. In the case that discussed, the clinical finding suggests a clinical case of leprosy with eyebrows involvement and multiple nodular lesions except for the short duration.

The authors have shown a correlation of aceclofenac intake with the myocardial infarction. This is really important in/brmation to be noted as aceclofenac or any nonsteroidal anti-inflammatory drugs （NSAI DS） of this group were prescribed more frequently worldwide.

This paper discusses the analysis done on the meteorological ocean buoy mooring used for monitoring the Indian seas. Based on the extreme environmental parameters experienced by the buoys, mooring loads are analyzed using offshore dynamic analysis software. The results obtained are validated with the tension recorder installed in one of the moorings, and the results are found to comply with an accuracy of better than 1%. The successful on demand performance of the mooring during major cyclones in the Bay of Bengal and the vital meteorological and oceanographic information provided by the buoy during these disastrous cyclonic events validates the mooring design, and proves the data availability for societal needs. The time critical data assimilated in the cyclone prediction models have given confidence to improve the country＇s weather prediction and climate modelling capabilities.

We present a diode-pumped, electro-optically Q-switched Tm:YAG laser with a cryogenically cooled laser crystal at120 K. Output pulses of up to 2.55 mJ and 650 ns duration were demonstrated in an actively Q-switched configuration with a repetition rate of 1 Hz. By using cavity dumping the pulse duration was shortened to 18 ns with only a slightly lower output energy of 2.22 mJ. Furthermore, using a simplified rate equation model, we discuss design constraints on the pump fluence in a pulse pump approach for Tm:YAG to maximize the energy storage capability at a given pump power.

目前,多数氨厂采用的氨合成压力在147～245×10~5帕(150～250绝压)之间。在传统的工厂里,氨合成回路的能耗每吨氨高达28×10~6千焦(6.7×10~6大卡),它系由各耗能项所组成(见表1)。如此高的能耗,已促进了对氨合成塔的改造,亦即通过改进设计对内件进行更换。一项新的节能氨合成系统正在开发之中,其能量消耗在整个回路装置中,可降低到24.8×10~6千焦(5.92×10~6大卡)/吨氨。

目的评估经皮活检、术中活检及肝脏射频消融过程中电磁导航、CT、超声及"氟-脱氧葡萄糖-正电子体层扫描(18F FDC PET,下称"FDG PET")(FDGPET)。PET多模融合实时反馈的可行性。方法此项研究通过了健康保险易移植性和责任性法案(HIPAA)认证和体制审查委员会的批准。于2007年11月至2010年8月,对25例患者(男17例,女8例)进行了33次经皮活检和3次术小活枪,共计36次FDC活性靶区域采样研究。其小,1例进行了活检与肝脏聚焦射频消融。在常规成像中,靶区分别表现出FDG摄取异常、没有显影不良或完全未显影。将术前FDGPET扫描与术吋,CT扫描采用半自动方法进行刚性配准。在同轴活检探针尖端和射频消融电极探针尖端内装入电磁传感器线圈,通过电磁场发生器进行空间定位。实时超声扫描则是利用基于基准配准法进行配准,这样可以使超声扫描与术中CT、预先FDGPET描的图像相融合。超声/CT的融合图像与叠加配准FDCPET靶区形成的图像可用于指导临床;通过导航软件实现实时针刺活枪、针电极导航及反馈。结果所有患者均成功进行了实时超声、CT定位与FDCPET扫描的融合。在36次活检中有31次接受厂诊断(18例恶性肿瘤,13例良性肿瘤)。射频消融会导致FDG活性的分解,在短期随防(56d)小未小现局部治疗失败事件。结论将实时反馈的图像与电磁装置跟踪相结合有助于特定的FDCPFT异常部位的活检与消融,这项研究将挑战传统的图像导航技术。
