The center of this rotunda, on the first floor is of heavy plated glass, to give light into that portion of the basement directly underneath. There are also additional balconies in the interior of the rotunda, above the fourth floor of the […] and is the interior crown of the dome ...
2. The color of the emitted light depends on the species, and its biological meaning has been discussed from various aspects, such as habitat or luminous behavior3,4,5. One of the notable observations is the relationship between habitat depth and color of bioluminescence in...
Dr. Russ has contributed a short illustrated article to the British Medical Journal for January 22 in which some interesting points are considered ing the seventeen octaves of radiations which are now available : from visible light to the gamma rays of radium. He deals very clearly with the X...
Regarding the determination of photocatalytic activity, the photodegradation trend of Acid Blue 9 dye or Bright Blue was monitored following exposure to photocatalyzed light from the adducts obtained using the previously described method [23]. Specifically, the photocatalytic activity of ZnO was evaluated...
where α is the absorption coefficient determined from the spectrometry data, c is the speed of light and λ is the wavelength. The dependence of both σo and σe on the photon energy for the investigated samples is plotted in Figure 4. Figure 4. Optical conductivity for the PVA and PVA...
Ultraviolet (UV) means ‘beyond violet’ (from Latin ‘ultra’, meaning ‘beyond’), whereby violet is the colour with the highest frequencies in the ‘visible’ light spectrum. By ‘visible’ we mean human vision, but, in comparison to many other organisms, human visual perception is rather...
