Nowadays, advanced turning processes are extensively being adopted to perform different types of operations such as straight turning, taper on Hastelloy, Nimonic, and Inconel, stainless steel, tool steel fabricate better quality cylindrical rotating parts miniature-bars, miniature-pins, miniature-electrodes, miniature-tools. This paper presents a review the previous research conducted miniature...

A photographic investigation of the surface discharges on specimens four polymeric materials is described. These are polystrene, polyvinyl chloride, teflon and prespex. Tests performed under A. C. voltage square each side length 10 cm thickness 0.5 mm to 6mm in non-uniform field consisting wire plane electrodes. The electrode has diameters ranged from 0.3 6 mm. inception found be dependent both...

We are developing A15 cables made of ultra-fine wires for react-and-wind （R&W） magnet technology. Recently, we fabricated a bronze processed multifilament Nb3Sn wire with diameter 50 µm. also prototype cable by stranding 19 testing. In this study, the transport critical current（Ic） was measured at 4.2 K and under an external field up to 18 T. The Non-Cu current density（Jc） calculated from Ic re...

objective: corrosion resistance is among the most important properties of metal alloys used in the oral cavity. consumption of acidic foods reduces the salivary ph and intensifies the corrosion of brackets and orthodontic wires. this study aimed to compare electro galvanic corrosion of different orthodontic brackets and wires and determine the amount of ions released into acidic artificial sali...

central venous catheterization (cvc) is a commonly performed procedure for venous access. it is associated with several complications. we report a rare case of extra luminal entrapment of guide wire during cvc placement in right jugular vein. we report a case of 28 years old female patient presented in our emergency with history of entrapped guide wire in right side of neck during cvc. x-ray sh...

This paper presents a new method called vespiary regular hexagonal (VRH) model in order to calculate parasitic capacitance between conductor wire filaments of one turn of coil (OTC) and between conductor wire filaments and liner and also total capacitance of one turn of the helix magneto flux cumulative generator (MCG) coil include single-layer conductor wire filaments in form of rectangular cr...

In this paper, a two-dimensional formulation is proposed for modeling the mechanical behavior of helical beam-like structures subjected to bending loads. Helical include multi-wire cables, which are widely used in engineering applications. An accurate representation their typically requires large-size three-dimensional finite element models. The formulation, written on cross-section only, offer...

The wire drawing process is extensively used in manufacturing components such as rivet, screw, welding wire, etc. In this work, an analytical of the wire drawing process has been considered for two-stage operation. ABAQUS commercial Finite Element code has been used to obtained the drawing force. Then, The analytical and experimental results been compared. The results show a good agreement for...

In the work titled ‘‘Ensuring Safety of Implanted Devices Under MRI Using Reversed RF Polarization,’’ the authors propose a method based on reversed polarization, which can be used as a prescan technique for patients with implants. In their work, to visualize qualitatively the induced radiofrequency (RF) currents on a metallic lead inside the patient, they propose to reverse the RF polarization...
