Certain copper alloys have proved to be suitable for laser cladding onto aluminium base. By using the blown powder technique with a 1.5 KW C02 laser, clads without cracks or porosity have been produced. The base material has the composition Al Si7 Mg0.3 and the clads are made from alloyed copper with varying contents of Ni, Fe, Si and Al. Aluminium dilution in the clad can be kept lower than 1 ...
In this article, we considered the field analysis in photonic crystal Bragg fibers. We apply the method of transmission matrix to calculater the dispersion curves, the longitudinal wave number over wave number versus incident wavelength, and the field distributions of TE and TM modes in the Bragg fiber. Our analysis shows that the field of guided modes is confined in the core and can exist onl...
We propose a new geometry of clad-pumped fiber amplifier/laser that includes at least one doped core which guides the signal wave and at least one clad region that guides the incoherent pump. Our proposed geometry enables the incoherent diode pump light to be efficiently absorbed by the doped glass core over very short lengths on the order of a few to tens of centimeters. The transparent claddi...
PurposeSurvival after lung transplantation (LTx) still remains limited by chronic allograft dysfunction (CLAD). Prior studies showed an association between graft cellular expression of the checkpoint HLA-G and acceptance, whereas conversely, soluble (sHLA-G) in plasma/BAL was associated with acute rejection. We investigated whether plasma levels extra-vesicular (EVs)-bound could predict CLAD.Me...

in this paper, the rolling force and reduction ratio have been investigated in multilayer strip rolling. for this purpose, two different set of multilayers have been selected which are al/st/al and cu/al/cu layouts. at first, the validation of the numerical analysis was performed by using an experimental test. after validation of the numerical results, two set of multilayer layouts were simulat...
