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 ...
Relativistic solitons in laser-plasma interaction
(AIP Conference Proceedings, 2002)
We discuss existence and stability of electromagnetic solitons in a relativistic interaction of a linearly polarized laser light with uniform underdense cold plasma. In a weakly relativistic NLS model with local and non-local ...
The austempering study of alloyed ductile iron
(Materials and Design, 2006)
Austempered ductile iron (ADI) proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness are combined with good wear resistance and machinability. These properties can ...
Dispersion hardened Cu-Al2O3 produced by high energy milling
(International Journal of Powder Metallurgy, 2000)
Prealloyed copper powders containing different amounts of aluminum (Cu-1w/oAl, Cu-2.5w/oAl and Cu-3.5w/oAl) were processed in a planetary ball mill to evaluate matrix hardening due to the formation of the formation of Al2O3 ...
Thermal diffusivity of cold sintered Co
(Materials Science Forum, 2004)
Cold sintering of cobalt powder (up to 1.2 GPa) was accompanied by measurements of density and thermal diffusivity. Dependence of density change upon pressing pressure is derived. Thermal diffusivity of the material was ...
Synthesis under self-controlled reaction conditions: Reaction of tetraamminezinc(II) chloride with 3,5-dimethyl-1-thiocarboxamide pyrazole
(Journal of Organometallic Chemistry, 2007)
The trinuclear [Zn-3(Hdmpz)(2)(dmpz)(4)(NCS)(2)] complex (Hdmpz: 3,5-dimethylpyrazole) has been synthesized by the reaction of tetraamminezinc(II) chloride with 3,5-dimethyl-1-thiocarboxamidepyrazole. The ammonia evolving ...
An efficient small scale TEA CO2 laser for material surface modification
(2002)
An efficient small scale TEA (Transversely Excited Atmospheric) CO2 laser has been considered, The laser was a low flowing, UV preionized, pulsed system. Specific design of the head as well as the electrical circuit ensure ...
A mathematical model of stress reaction: Individual differences in threshold and duration
(Psychobiology, 2000)
People differ in what they experience as stressful and to what extent. We define a variable-stress threshold (sigma)-that links the hypothalamo-pituitary-adrenocortical (HPA) axis and the memory system in a feedback ...
Heavy flavor identification using multivariate analysis at H1
(AIP Conference Proceedings, 2009)
We discuss b quark identification in deep inelastic scattering of electron on proton at HI by applying multivariate analysis method. Separation between heavy and light flavors can be further used to extract proton quark content.
