Basic dosimetric properties of 6 MV and 10 MV photon beams from a linear accelerator operating without the flattening filter have been analyzed. These include dose rate data, depth dose dependencies, lateral profiles and ...

The analytical methods based on X-ray fluorescence have a great importance for a number of practical applications in a variety of fields including atomic physics, X-ray fluorescence surface chemical analysis, medical ...

Study the cosmic microwave background: polarization and anisotropy.The inflationary model has been proposed to address the shortcomings of the standard model of cosmology. This cosmological model offers both a solution to ...

The origin of ultra-high-energy cosmic rays is one of the most enigmatic questions in modern physics. The study of a such high-energy particles is a new and active research area where scientists wish to find the still-unknown ...

Ever since the discovery of cosmic rays by Victor Hess [Hes12] in 1912 great efforts have been undertaken to understand the origin of cosmic rays up to the highest energies of 1021eV. A common detection method utilizes the ...

The present study examines the PbS semiconductor nanoparticles trapped in Y zeolite synthesized at room temperature via a simple chemical reaction when 2-mercaptoethanol noted RSH was used with a different amounts as a ...

L’objectif de cette étude est la préparation et la caractérisation de nanoparticules bimétalliques Ni-Ce et Ni-Pt supportés sur α-Al2O3. Ces matériaux sont testés comme catalyseurs dans la réaction d’hydrogénation du ...

The mechanical properties of materials are determined by the interactions between defects found in the crystal. In a bicrystal of bimaterials, the result forces exercising on the matrix dislocation near and parallel to an ...

Imidazole, an aromatic heterocyclic, classified as an alkaloid, is present as an antifungal agent in commercial pharmaceutical products [1-2]. A novel 3D crystal structure of the title compound {(C3H5N2)[Na(NO3)2]}n ...

We report here on the effect of aluminum doping and annealing temperature on the structural properties of ZnO, synthetized using the Sol Gel method. Aluminum doping was performed in two ways, either by adding AlCl3 to the ...
