The article by Lim et al was an insightful description of the late sequalae of the coronary artery in a patient with prior Kawasaki disease during infancy. Late diagnosis and treatment with intravenous immunoglobulin could have predisposed this patient to develop severe and persistent coronary artery aneurysm(CAA). CAA has typical predilection for ostial-proximal, left main and bifurcation segm...
The VISA (Visible to Infrared SASE Amplifier) FEL is designed to obtain high gain at a radiation wavelength of 800nm. The FEL uses the high brightness electron beam of the Accelerator Test Facility (ATF), with energy of 72MeV. VISA uses a novel, 4 m long, strong focussing undulator with a gap of 6mm and a period of 1.8cm. To obtain large gain the beam and undulator axis have to be aligned to be...
This study is an attempt to obtain a suitable combination of the milling parameters optimize electrical power and material removal rate (MRR) in slot aluminium 6061. Machining radial depth cut (RDOC), feedrate (Fr) axial (ADOC) are optimized using high efficiency cutting strategy. The results analyzed through response surface ANOVA for MRR. Response optimization shows that RDOC=48.8 mm, Fr=3000...
A finite element model is constructed to analyze the steady heat conduction and thermal stress in a ceramic/FGM/metal composite EFBF plate under convective heat transfer boundary. From numerical calculation, when 1 b a , T0=Ta =300K and Tb=1 800K, the steady heat conduction and thermal stress distributions in the plate were obtained. The numerical results show that the temperature distr...
The current paper describes the design of Fiber Optics Links for BTeV’s Pixel Detector readout. BTeV pixel detectors chips will be located as close as 6mm from the accelerator’s beam into the vacuum pipe. The readout electronics will be located at about 6cm from the beam, imposing strong constrains regarding radiation, mass, power dissipation, and size. The current development is the first prot...

Patient motion compensation is challenging for dynamic 2D/3-D overlay in interventional procedures. A first motion compensation approach based on depth-layers has been recently proposed, where 3-D motion can be estimated by tracking feature points on 2-D X-ray images. However, the sparse depth estimation introduces a systematic error. In this paper, we present a theoretical analysis on the syst...
The title compound, terbium hexa-niobium hexastannide, TbNb(6)Sn(6), is the first ternary compound from the rare earth-niobium-tin system. It has the HfFe(6)Ge(6) structure type, which can be analysed as an inter-growth of the Zr(4)Al(3) and CaCu(5) structures. All the atoms lie on special positions; their coordination geometries and site symmetries are: Tb (dodeca-hedron) 6/mmm; Nb (distorted ...
in different folk medicine ziziphus spina-christi is used for different purposes such as pneumonia, dysentery, scorpion stings, cough, constipation, intestinal worms and fever. the aim of this study was evaluation and comparing the antibacterial activity of methanolic and ethanolic extracts of ziziphus spina –christi as well as subsequent structural changes in affected bacteria. for this purpos...
Background and aims: X-band microwave with 8-12.5 frequency range has various applications such as air control traffic, navy communication and etc. Uncontrolled exposure with microwave can lead to adverse effect on workers. Application of the shielding is superior control for prevention of microwave exposure.The aim of this study is production a new electromagnetic shielding for exposure contr...
