AIM To study the optical properties of human normal small intestine tissue at 476.5 nm, 488 nm, 496.5 nm, 514.5 nm, 532 nm, 808 nm wavelengths of laser irradiation. METHODS A double-integrating-sphere system, the basic principle of measuring technology of light radiation, and an optical model of biological tissues were used in the study. RESULTS The results of measurement showed that there ...

Este artículo analiza la vertiente conceptual y plástica de los retratos post mortem efectuados por Gustav Klimt. Una labor que ejerce excepcionalmente, como otros pintores historia del arte, aunque el caso este artista es destacado abordarla desde campo profesional al personal. En aspecto, presente texto pone relieve significativos trabajos realizados Klimt, entre 1883 1912, tanto encargos pri...

The cation deficient complex oxides of (Ca/Sr)MoO4 - BiVO4 Bi2Mo3O12 triple system are promising photocatalysts and pigments. Compounds with general formula Ca1−1.5x-yBix+yФxMo1-yVyO4 Sr1−1.5x-yBix+yФxMo1-yVyO4 were synthesized byconvention solid state technique in the range 550–720 °C. Two wide regions solutions (ordinary superstructured scheelite-type phases respectively) found for each syste...

The determination of the band gap energy (Eg) semiconductors powder materials can be performed from diffuse reflectance spectroscopy (DRS) measurements. For this purpose, classical theory proposed by Kubelka and Munk (K-M) so-called plot Tauc, both discussed here, have been largely employed. We investigate Eg values anatase TiO2 particles synthesized precipitation titanyl sulphate in presence 5...

We present a prediction model for digital printers and more specifically for electrophotographic devices. On the one hand, we propose an electrophotographic simulation model which estimates the microscopic structure of any printed toner layer based on its input halftone bitmap. Applying BOUGUER–BEER–LAMBERT’s law, the obtained spatial toner arrangement yields the spectral transmittance distribu...
