The angle-resolved photoelectron spectroscopy of isolated silver sulfide nanoparticles was carried out by using velocity map imaging technique at the DESIRS beamline SOLEIL synchrotron facility. reported results were obtained after interaction radiation with a polydisperse aerosol produced from aqueous dispersion particles, approximately 16 nm in diameter. and UV–Vis-NIR absorption spectra used...

Light-absorbing materials are widely used, and their optical properties an important factor. Snell's law does not hold in that partially absorb light. Hence, the path refraction is calculated from Maxwell's law. We used to obtain deviation angle when a light passes through prism made of light-absorbing material. The has local maximum. near maximum sensitive real imaginary parts refractive index...

Secondary and tertiary structures of tRNAs are remarkably preserved from bacteria to humans, the notable exception being the mitochondrial (m) tRNAs of metazoans, which often deviate substantially from the canonical cloverleaf (secondary) or 'L'-shaped (tertiary) structure. Many metazoan mtRNAs lack either the TpsiC (T) or dihydrouridine (D) loops of the canonical cloverleaf, which are known to...

OBJECTIVE Cardiac involvement as pericarditis, myocarditis and valvular disease is common in juvenile idiopathic arthritis (JIA). However, there are few studies concerning systolic and diastolic functions of the left ventricle in children with JIA. P wave dispersion is a sign for the prediction of atrial fibrillation. A recent study found that rheumatoid arthritis patients had an abnormally hig...

The multi-angle imaging spectroradiometer (MISR) instrument is designed to provide global imagery at nine discrete viewing angles and four visible/near-infrared spectral bands. The MISR standard products include vegetation canopy green leaf area index (LAI) and fraction of photosynthetically active radiation absorbed by vegetation (FPAR). These products are produced using a peer-reviewed algori...
