The presence of dust in starburst galaxies complicates the study of their stellar populations as the dust’s effects are similar to those associated with changes in the galaxies’ stellar age and metallicity. This degeneracy can be overcome for starburst galaxies if UV/optical/near-infrared observations are combined with far-infrared observations. We present the calibration of the flux ratio meth...

Recent work by the authors and others has shown that MR imaging is more sensitive than CT in the detection of acute stroke. To separate the effects of water content and water structure on MR signal intensity, we undertook two sets of experiments that used simple model systems: gelatin gels with increasing water content and hardened hens' eggs. CT and MR were performed on both systems. On CT the...

We calculate the radiation shielding parameters of CoCrFeNiTiAlx alloys which consist mass attenuation coefficient, linear mean free path, half-value layer, total atomic cross section, effective number and electron number. For this, we use recently developed Phy-X/PSD EpiXS softwares. compare all results with each other, discuss relationship between results.

Penta-glasses with a 59B2O3–29SiO2–2LiF–( $$10-x$$ ) ZnO– $$x$$ TiO2 composition the melt-quench techniques were prepared. X-ray diffraction was used to examine nature of fabricated glasses. The changes in structure glasses studied by Fourier-transform infrared spectroscopy spectra. molar volume reduces as density increases. mechanical characteristics these evaluated. Besides, for glasses, Phy-...
