In this paper, tetragonal chalcopyrite (CIGS) Cu(InxGa1-x)Se2 with x=0, 0.5, 0.8, 1 are synthesized by heating-up method. These nanoparticle structures differ in morphology and absorption properties due to the synthesis temperatures of 250, 255, 260, 265, 270 and 280 ºC, and gallium molar ratio over the total gallium and indium contents. These features are studied using scanning electron m...

drying of green peas in a fluidized bed dryer (fbd) with inert particle, heated by combined sources of hot air and infrared (ir) radiation, has been experimentally and theoretically studied. for this purpose, an experimental set up was constructed. this setup was composed of a cylindrical bed dryer containing some inert particles which are fluidized by hot air. some infrared lamps were also pla...

We report high-speed real-time PCR performed on an unmodified disposable polystyrene Petri dish. The reaction cycle relies solely on an infrared laser for heating; no conventional heater is required. Nanoliter droplets of PCR mixture as water-in-oil emulsions printed in an array format served as individual PCR microreactors. A simple contact printing technique was developed to generate a large ...

We present high-resolution hydrodynamical simulations of isolated dwarf galaxies including self-gravity, non-equilibrium cooling and chemistry, interstellar radiation fields (ISRF) and shielding, star formation, and stellar feedback. This includes spatially and temporally varying photoelectric (PE) heating, photoionization, resolved supernova (SN) blast waves and metal enrichment. A new flexibl...

Quality and authenticity control serve as the customers' and manufacturers' insurance, and thus the development of analytical tools providing these tasks represents an important step of each product development. The control of authenticity in food manufacturing is even more important due to the direct influence of its products on the health of the population. This study sought to develop an eas...

Among the widely used Non-Destructive Testing and evaluation approaches, InfraRed Thermography has proven to be one of the vital NDT technique due to its inherent capabilities for testing and evaluation of various solid materials. Nevertheless, there are some limitations; depending upon the test approach used, as well as the adopted data processing method. In active approach of infrared thermog...

Synchrotron radiation-based Fouriertransform infrared (SR-FTIR)spectromicroscopy is a newly emergingbioanalytical and imaging tool. This uniquetechnique provides mid-infrared (IR)spectra, hence chemical information, withhigh signal-to-noise at spatial resolutionsas fine as 3 to 10 microns. Thus it enablesresearchers to locate, identify, and trackspecific chemical events within anindividual livi...

The autonomic nervous system has a regulatory structure that helps people adapt to changes in their environment by adjusting or modifying some functions in response to stress, and regulating involuntary function of human organs. The purpose of this study was to investigate the effect of combined stimulation, both far-infrared heating and chiropractic, on the autonomic nervous system activities ...

Context. Aims. Recent observations derived from the Spitzer Space Telescope and improvements in theoretical modeling of dust emission properties are used to discuss the distribution of dust and its characteristics in the closest neighbor spiral galaxy M31. Together with GALEX FUV, NUV, and SDSS images we studied the age dependence of the dust heating process. Methods. Spitzer IRAC/MIPS maps of ...

Near-infrared (NIR) spectroscopy is a noninvasive optical technique that is increasingly used to assess muscle oxygenation during exercise with the assumption that the contribution of skin blood flow to the NIR signal is minor or nonexistent. We tested this assumption in humans by monitoring forearm tissue oxygenation during selective cutaneous vasodilation induced by locally applied heat (n = ...
