In this paper, Au nanoparticles are synthesized by solution method. The effect of these nanoparticles on the Bi1.6Pb0.4Sr2Ca2Cu3Oy superconductor properties has been investigated. The critical current density, activation energy and room temperature resistivity were measured by the standard four-probe method. The microstructure and morphology of samples have been studied by X-ray diffraction, Sc...

The distribution of the solar cosmic radiation flux over the earth is not uniform, but the result of complex phenomena involving the interplanetary magnetic field, the geomagnetic field and latitude and longitude of locations on the earth. The latitude effect relates to the geomagnetic shield; the longitude effect relates to local time. For anisotropic solar cosmic ray events the maximum partic...
Background and purpose: Âpoptosis or programmed cell death is a process of cell suicide. Ïonizing radiation is one of the stimuli for apoptosis, acting through DNÂ damage. Ïn the present study, effects of x-rays induced apoptosis in HL60 cells, as well as the protective effects of SÇF( Stem Çell Factor) in inhibiting x-ray induced apoptosis have been evaluated. Materials and methods : Ëxpo...
We report an anticorrelation between continuum luminosity and the equivalent width (EW) of the Hα emission line in X-ray binary systems. The effect is evident both in a universal monotonic increase in Hα EW with time following outbursts, as systems fade, and in a comparison between measured EWs and contemporaneous X-ray measurements. The effect is most clear for black hole binaries in the low/h...
