1 Only use electrical devices with 3-conductor power cords and 3-prong plugs (Figure 1 shows a plug with a broken ground prong – do not use). 2 Do not use cheater plugs (3-prong to 2-prong adapters, Figure 2). They eliminate the ground connection and increase the possibility of serious shock hazards. 3 Always unplug equipment by grasping the plug, not the cord. 4 Routinely check equipment power...

In this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % Si non-oriented electrical steel was investigated. For this purpose, all samples were processed through single-stage hot rolling at 1100 ° C and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °C for 35 seconds. Finally, all of them were fu...

In this paper, semi-analytical method for asymmetrical eccentrically stiffened FGM cylindrical shells under external pressure and surrounded by a linear and non-linear elastic foundation is presented. The proposed linear model is based on two parameter elastic foundation Winkler and Pasternak. According to the von Karman nonlinear equations and the classical plate theory of shells, strain-displ...

<span>This paper presents a novel shunt active power filter (SAPF). The converter that is used in this SAPF constructed from four-leg asymmetric multi-level cascaded H-bridge (CHB) inverter fed photovoltaic source. A three-dimensional space vector modulation (3D-SVPWM) technique adopted work. can generate 27-level output with harmonic content almost zero. In addition to the capability inj...

at the final stages of a coronary artery bypass graft operation on a 64-year-old man, an experienced physician attempted to insert an intra-aortic balloon pump into the femoral artery via the seldinger technique. however, while the balloon pump was being passed over the guide wire, the latter was completely lost. the guide wire should be held at the tip at all times to prevent passage into the ...

Cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. Elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. In this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

the effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. in this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. the results were the minimum interlamellar spacing of 35 nm and maximum ulti...

There is an increasing interest in developing porous metals or metallic foams for functional and structural applications. The study of the physical and mechanical properties of porous metals is very important and helpful for their application. In this paper, a novel sintered multilayer wire mesh porous plate material (WMPPs) with a thickness of 0.5 mm-3 mm and a porosity of 10-35% was prepared ...
