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) ...
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 ...
Three- and four-jet production at low x at HERA
(European Physical Journal C. Particles and Fields, 2008)
Three- and four-jet production is measured in deep-inelastic ep scattering at low x and Q(2) with the H1 detector using an integrated luminosity of 44.2 pb(-1). Several phase space regions are selected for the three-jet ...
Composites comprising CdS nanoparticles and poly(ethylene oxide): optical properties and influence of the nanofiller content on the thermal behaviour of the host matrix
(Colloid and Polymer Science, 2008)
Tri-n-octylphosphine oxide-capped CdS nanoparticles were synthesized with the cadmium(II) complex of thiocarbohydrazide as a precursor. Nanocomposites were prepared by mixing a toluene solution of poly(ethylene oxide) (PEO) ...
Closed-form summation of two families of finite tangent sums
(Applied Mathematics and Computation, 2008)
In our recent paper with Srivastava [D. Cvijovic, H.M. Srivastava, Summation of a family of finite secant sums, Appl. Math. Comput. 190 (2007) 590-598] a remarkably general family of the finite secant sums was summed in ...
Chiral properties of baryon interpolating fields
(European Physical Journal C. Particles and Fields, 2008)
We study the chiral transformation properties of all possible local (non-derivative) interpolating field operators for baryons consisting of three quarks with two flavors, assuming good isospin symmetry. We derive and use ...
Transition metal complexes with Girard reagent-based ligands. Part IV. Synthesis and characterization of pyridoxilidene Girard-T hydrazone complexes. Crystal structure of the copper(II) complex
(Structural Chemistry, 2008)
The monoligand complexes of the formula M(HPLGT)(NCS)(2) (M = Cu(II), Zn(II)) in which the ligand tridentate ONO pyridoxilidene Girard-T hydrazone, [H(3)PLGT]Cl(2) center dot 2H(2)O, was coordinated in neutral doubly ...
Antiproton therapy
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2008)
Radiotherapy is one of the most important means we have for the treatment of localised tumours. It is therefore essential to optimize the technique, and a lot of effort goes into this endeavour. Since the proposal by Wilson ...
In vitro radiosensitivity of Fanconi anemia fibroblasts measured by gamma-H2AX foci
(FEBS Journal, 2008)
Fanconi anemia (FA) is a genetically heterogeneous disease character-ized by bone marrow failure, congenital abnormalities and a significantpredisposition toward malignancies. Fanconi cells are highly sensitiveto DNA ...
