Abstract The investigated cast Ni50–Ti50 shape memory alloy was prepared using a vacuum arc furnace. samples were subjected to in-vitro biocompatibility studies according ISO 10993-12:2004, and compared other Ni–Ti orthodontic wires commercially available at the dental market. hydroxyapatite-coated electrodeposition technique. effect of surface treatment on coating quality addressed. electroche...

Cerclage wires are regularly hired as fixation gear to resource reposition, enhance alignment and growth stability. In specific femoral shaft, subtrochanteric periprosthetic fractures gain from cerclage fixation. Also in supracondylar shaft fractures, extra cord cerclages proved be than only a reposition device accelerated the general power of osteosynthesis construct. This study tests for stab...

The giant magneto-impedance (GMI) effect has been studied in 3 different families of amorphous wires: conventional amorphous wires (125 μm in diameter), cold drawn wires (50 and 20 μm in diameter) and thin glass coated amorphous microwires (with metallic nucleus diameter of about 15 μm). These wires have been investigated in the frequency range 1 – 500 MHz. A remarkable difference in the magnet...

OBJECTIVE This research aimed at comparing the qualitative chemical compositions and the surface morphology of fracture regions of eight types of Nickel/Titanium (NiTi) conventional wires, superelastic and heat-activated (GAC, TP, Ormco, Masel, Morelli and Unitek), to the wires with addition of copper (CuNiTi 27ºC and 35ºC, Ormco) after traction test. METHODS The analyses were performed in a ...

Concern about the performance of wires in scaled technologies has led to research exploring other communication methods. This paper examines wire and gate delays as technologies migrate from 0.18m to 0.035m feature sizes to better understand the magnitude of the wiring problem. Wires that shorten in length as technologies scale have delays that either track gate delays or grow slowly relative t...

Strong asymmetry of electron mobility in InGaAs/InAlAs heterostructures (lattice matched to InP) with the presence of InAs quantum wires was observed. Self-assembled InAs quantum wires, embedded in an InGaAs matrix close to the hetero-interface, has a strong effect in electron conduction in the interface channel. The low temperature mobility for electrons moving parallel to the quantum wires is...

BACKGROUND Temporary epicardial pacing wires are routinely used during cardiac surgery; they are dependable in controlling postoperative arrhythmias and are associated with low morbitity. CASE REPORT We report a case of sternobronchial fistula formation induced by the existence of retained epicardial pacing wires in a patient who underwent coronary surgery ten years ago. CONCLUSION Reported...

We study the Coulomb interaction effects on the tunneling conductance of a contact constructed of two parallel quantum wires. The following contacts are considered: two clean identical quantum wires, two disordered identical quantum wires, and asymmetric contact of one clean and another disordered quantum wires. We show that the low-voltage anomaly of the tunneling conductance is less singular ...

We focus on inducing topological state from regular, or irregular scattering in (i) p-wave superconducting and (ii) proximity coupled Rashba wires. We find that while disorder is detrimental to topological state in p-wave wires, we find that it can induce topological state in Rashba wires contrary to common expectations. We find that the total phase space area of the topological state is conser...
