    Abstract: Iron–phosphate glasses containing heavy metal cations are important material, especially when used to attenuate γ-ray and / or fast neutrons. Therefore, some glasses had been prepared, having the composition [(70 mol % P2O5. 15 mol % Na2O. 15 mol % Fe2O3) + x CdO, where 0 ≤ x ≤ 30 mole]. The melting temperature was 1200 ºc and the annealing tempera... Show More

    Abstract: Generation of calibration curves for radiation detectors are essential in radiation spectroscopy. Such curves usually relate some characteristic quantities of measured samples (such as radioactivity of a certain isotope or its mass) with the output of the used detector (counting rates). The most direct and easiest way to generate these curves is pe... Show More

    Abstract: In this paper, I focus on describe, calculate and analyze of molecular dynamic (MD) simulations using wavelet transform (WT) techniques by analogy with its use in signal and image processing, so that I would like to talk about the theoretical background wavelet transform methods, including what properties they have, their common types, and how to o...

    Abstract: A single field emerged at the origin of the universe, already containing within itself the blueprint of the physical universe. The primordial single field triggered the onset of the universe. Most physicists believe that a single super-force dominated the first instants of creation. Scientists have arrived at a simple but decisive conclusion that c... Show More
