Investigation of the projectile atomic number influence to the total sputtering yield in the keV energy region
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2008)
The non-monotonous dependence of the total sputtering yield on the projectile atomic number, which is unexpected in the frame of the Sigmund linear cascade theory, is investigated using Monte Carlo simulations (program ...
Closed-form evaluation of some families of cotangent and cosecant integrals
(Integral Transforms and Special Functions, 2008)
Several families of integrals involving the cotangent or cosecant function have been evaluated in closed form by making use of elementary arguments. Some of them are expressible in terms of the values of the (generalized) ...
Kinetics of the alpha-beta Phase Transformation in Seeded Si3N4 Ceramics
(Science of Sintering, 2008)
The alpha-beta phase transformation in Si3N4 was studied for seeded samples using all Y2O3-Al2O3 mixture as a sintering aid. The concentration of beta-seeds varied from 0 to 5 wt.%. The results showed that alpha-beta phase ...
Masses of tetraquark candidates D-S(+)(2317) and D-S(+)(2632) using Glozman-Riska hyperfine interaction
(Fortschritte der Physik = Progress of Physics, 2008)
Using the Glozman-Riska (flavor-spin) interaction Hamiltonian and the SU(3) flavor symmetry breaking, we perform a schematic study of the masses of the scalar charmed tetraquarks in the following representations: (15) over ...
Distribution of stable isotopes in the River Sava in Serbia
(Nukleonika, 2008)
Grab water samples were collected from the research ship ARGUS at four locations in Serbia, Ostruznica (17 rkm), Sabac (103.6 rkm), Sremska Mitrovica (136.4 rkm), and Jamena (195.0 rkm) from the mid-river, and near the ...
Bright solitons in the one-dimensional discrete Gross-Pitaevskii equation with dipole-dipole interactions
(Physical Review A, 2008)
A model of the Bose-Einstein condensate of dipolar atoms, confined in a combination of a cigar-shaped trap and deep optical lattice acting in the axial direction, is introduced, taking into regard the dipole-dipole (DD) ...
Comparison of Eu Framework and Daughter Directives and Current Serbian Legislation on Air Pollution Monitoring
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2008)
This paper discusses the air quality control in the current legislation of the Republic of Serbia and compares it with the relevant EU legislation, Framework and Daughter Directives of the air quality monitoring and ...
In Situ Lead Stabilization Using Natural and Synthetic Apatite
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2008)
In this work, mineral apatite was investigated for the remediation of lead contamination. Two different apatite minerals were used: synthetic apatite, Ca(10)(PO(4))(6)(OH)(2) (hereafter denoted as HAP) and natural apatite ...
Experimental and theoretical study of lattice relaxation around refractory atoms in nickel
(Acta Materialia, 2008)
The lattice relaxation around Mo, Ru, Hf, Ta, W and Re in Ni is investigated by means of X-ray absorption spectroscopy. For all of the investigated concentrations the substitutional lattice position is confirmed except for ...
Traces of DU in samples of environmental bio-monitors (non-flowering plants, fungi) and soil from target sites of the Western Balkan region
(Journal of Environmental Radioactivity, 2008)
This paper reports results of gamma and alpha spectrometric measurements for mosses, lichens, fungi and soil samples from areas in the Balkans targeted by depleted uranium (DU). Samples were collected in 2002 and 2003 in ...
