Mid-infrared (IR) supercontinuum (SC) lasers are important in applications such as pollution detection, stand-off and non-destructive testing. The performance many is limited by the noise level of laser. High typically results low sensitivities or a need for long integration times. In this paper, simple technique to reduce high soliton-based SC sources introduced adding short piece normal dispe...

BACKGROUND Noise pollution is currently a major risk factor in industries in both developed and developing countries.The present study assessed noise pollution in the knitting industry in Iran in 2009 and presented a control method to reduce the rate of noise generation. METHODS The overall noise level was estimated using the network environmental noise assessment method in Sina Poud textile ...

The mid-infrared (mid-IR) region, covering the electromagnetic spectrum from about 2.5 to 25 ┤m wavelength, is of unique interest for many applications, especially for molecular spectroscopy, because the vibrational frequencies of almost all target molecules and hydrocarbons are in this spectral region, such as NO, NO2, CO, CO2, HF, and CH4. The specific application areas for molecular spectros...

during the last few years, ir scholars in iran have been called to develop international relations theories from an iranian point of view. this article seeks to examine the structural context within which such an attempt is going to be made. the five components of this context have been recognized: the international position of iran, basic islamic/iranian sources, dynamism of ir community in ir...

in this paper, calcium stannate nanoparticles were synthesized by a fast and simple co-precipitation procedure. for casno3 preparation ammonia was used as precipitation agent. the effect of various surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. by changing in ca(sal)2 as a new precursor different morphologies were obtained. ligand as a capp...

malicorium supported ni0.5zn0.5fe2o4 magnetic nanoparticles were synthesized by a low-cost, simple,and environmentally benign procedure. the adsorbent was characterized by several methods includingx-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform infraredspectroscopy (ft-ir). then, the potential of malicorium supported ni0.5zn0.5fe2o4 magneticnanoparticles was in...

BACKGROUND Epidemiologic and experimental studies support an association between PM2.5 exposure and insulin resistance (IR). Innate immune cell activation has been suggested to play a role in the pathogenesis of these effects. OBJECTIVES We sought to evaluate the role of CC-chemokine receptor 2 (CCR2) in PM2.5-mediated inflammation and IR. METHODS Wild-type C57BL/6 and CCR2-/- male mice wer...

background: spindle trees (euonymus japonica thunb.) growing in an industrial complex area containing pollutants is chronically injured thus need to build up their resistance. antioxidant enzymes and cell membrane stability have been widely used to differentiate stress tolerance. materials and methods: leaves of spindle trees from a clean control area (kijang) and an industrial area (onsan) whe...

In this paper, calcium stannate nanoparticles were synthesized by a fast and simple co-precipitation procedure. For CaSnO3 preparation ammonia was used as precipitation agent. The effect of various surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. By changing in Ca(Sal)2 as a new precursor different morphologies were obtained. Ligand as a capp...

Modulated tone-burst light was employed to measure non-radiative relaxation time of fluorophores with biomedical importance through photoacoustic effect. Non-radiative relaxation time was estimated through the frequency dependence of photoacoustic signal amplitude. Experiments were performed on solutions of new indocyanine green (IR-820), which is a near infrared dye and has biomedical applicat...
