Two routes to the one-dimensional discrete nonpolynomial Schrodinger equation
(Chaos, 2009)
The Bose-Einstein condensate (BEC), confined in a combination of the cigar-shaped trap and axial optical lattice, is studied in the framework of two models described by two versions of the one-dimensional (1D) discrete ...
Phase-transformation kinetics in triphasic cordierite gel
(Journal of Materials Research, 2001)
A triphasic cordierite-type gel was prepared from silica sol, boehmite sol, and an aqueous solution of Mg(NO3)(2). 6H(2)O. The silica sol was obtained from water glass by the ion exchange method, while boehmite sol was ...
Three-dimensional modeling of utility boiler pulverized coal tangentially fired furnace
(International Journal of Heat and Mass Transfer, 2006)
This paper presents selected results of numerical simulations of processes in utility boiler pulverized coal tangentially fired dry-bottom furnace. The simulations have been performed by specially developed comprehensive ...
Detection of malathion by the CO2 laser: Potentials and limitations
(Analytica Chimica Acta, 2006)
Possibilities of on-line non-contact detection of the vapour of the commercially available pesticide malathion by the CO2 laser were investigated, using a photoacoustic technique developed in our laboratory. A set of ...
Modification of carbon cloth by interaction with pulsed TEA CO2 laser
(Materials Science Forum, 2004)
The interaction of a Transversely Excited Atmospheric (TEA) CO2 laser (pulse duration less than 2 mus) with carbon and activated carbon cloth was investigated. The investigations have shown that carbon cloth had been ...
Thermodynamic limit for the Ising model on the Cayley tree
(Physica A: Statistical Mechanics and Its Applications, 2005)
While the Ising model on the Cayley tree has no spontaneous magnetization at nonzero temperatures in the thermodynamic limit, we show that finite systems of astronomical sizes remain magnetically ordered in a wide temperature ...
The CMS high level trigger
(European Physical Journal C. Particles and Fields, 2006)
At the Large Hadron Collider at CERN the proton bunches cross at a rate of 40 MHz. At the Compact Muon Solenoid experiment the original collision rate is reduced by a factor of O (1000) using a Level-1 hardware trigger. A ...
Synthesis of Si3N4-celsian composite materials
(Ceramics International, 2000)
The synthesis of Si3N4-celsian composite materials was studied in this paper. To obtain celsian, two different types of additives were used. In the first case the appropriate mixture of BaCO3, Al2O3 and SiO2 was added to ...
Atmospheric pollution in the belgrade metropolitan area
(2005)
In the last decade air pollution represents one of the major environmental issues and is becoming a very important factor of the quality of life in urban areas, posing a risk both to human health and to the environment. ...
Insulin modulates rat liver glucocorticoid receptor
(Acta Biologica Hungarica, 2006)
This investigation used cytosol fraction of rat liver to examine the effects of insulin ( INS) on functional properties of glucocorticoid receptor ( GR). Male Wistar rats ( 220 - 250 g b.wt.) were injected with INS ( 50 ...
