As described in the first part of this article, Evidence Based Medicine (EBM) is a growing part of medical practice which emphasizes on the best evidence. Finding this evidence by formulating an answerable question and searching strategies were described in the first part of this review. In this part, appraising the retrieved article (with the main focus on the diag...

This paper presents a stability investigation of a special-shape arch bridge with a span of 180 m. Its structure and mechanics are significantly different from normal arch bridges because of its single arch rib skewing across the girder, its hangers hanging unevenly along the arch rib with different aslant angle, and its arch rib being subjected to massive axial compression force, bending momen...

<span>Beam steering antennas is essential part of various WCN (Wireless Communication Networks) such as radar and satellite communication. The increasing demand high data rate, SNR (Signal to Noise Ratio) gain, therefore pattern reconfigurable are required improve properties. </span><span>Beam the technique changing main lobe direction radiation. constructive distractive inter...

The instability of extraction structure under the undercut space in block caving stope presents specific characteristics: rib spalling and floor heave ore-loading roadway collapse major apexes. In order to study stress displacement evolution law reveal mechanism structure, numerical simulation model was established using finite difference software FLAC3D. According postundercutting strategy Ton...
