background: peroxisome proliferator activated receptor gamma (pparγ), a member of nuclear receptor superfamily, comprises two isoforms in mouse. these two isoforms are encoded by different mrnas, which are arisen by alternative promoter usage. there are two promoter regions upstream of pparγ gene. a 3 kb fragment, containing several transcription factor binding sites, acts as pparγ1 promoter re...

   Diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (OM), microhardness depth profiling (HDP), scanning electron microscopy (SEM), x-ray diffraction (XRD), glow discharge optical emission spectroscopy (GDOES), and secondary ion mass spectroscopy (SIMS). Plasma ni...

Pure and ZnO-doped Ni0.1Co0.9Fe2O4 catalyst were prepared by co-precipitation method and thermal decomposition in air calcinated at 400-700°C and that treated with different amounts of zinc nitrate (0.46-2.25 w% ZnO). X-ray powder diffractometry, scanning electron microscopy (SEM) and BET analysis of nitrogen adsorption isotherms investigated the crystalline bulk structure and the surface area ...

We have developd new techniques that enable characterization of ultrafast optical waveforms generated via spectral line-by-line pulse shaping under the Optical Arbitrary Waveform Generation (O-AWG) program. Our approaches simultaneously address a number of challenging requirements not met by existing waveform measurement methods, including high waveform complexity, high spectral resolution, and...

Cadmium Sulphide (CdS) nanoparticles were prepared using microemulsion method using cadmium chloride as cadmium source and sodium sulphide as sulphur source. The obtained nanoparticles structures were characterized by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) whereas optical characterization was done by Ultra Violet-Visible absorption. XRD result shows that CdS nanopart...
