Canonical approach to 2D supersymmetric WZNW model coupled to supergravity
(Modern Physics Letters A, 2002)
Starting from the known representation of the Kac-Moody algebra in terms of the coordinates and momenta, we extend it to the representation of the super Kac-Moody and super Virasoro algebras. Then we use general canonical ...
Influence of non-uniformity of coal and distribution of active calcium on sulfur self-retention by ash - A case study of lignite Kolubara
(Energy and Fuels, 2002)
Self-retention Of SO2 by ash of different grades of Kolubara lignite was experimentally investigated in a laboratory furnace. The peculiarity of this type of coal is that in the open pit there are distinct layers of coal ...
Dielectric studies of molecular beta-relaxation in low density polyethylene: the influence of drawing and ionizing radiation
The dielectric relaxation behavior of low density polyethylene, uniaxially oriented to different draw ratios (3, 7 and 10) and irradiated to different absorbed doses (100, 200, 300, 500 and 700 kGy) of gamma radiation was ...
The effect of DNA polymorphisms in angiotensin I-converting enzyme and angiotensin II type1 receptor genes with arterial blood pressure levels in Serbian population
(European Journal of Human Genetics, 2002)
Synthesis and biological evaluation of new pyrazole- and tetrazole-related C-nucleosides with modified sugar moieties
3(5)-Carboxamido-4-(beta-D-ribofuranosyl)pyrazoles bearing 2-benzamido (15) and 3-mesyloxy (29) isosteric groups, as well as the tetrazole C-nucleosides with 2-benzamido-2-deoxy-beta-D-ribofuranose (19) and 3-azido-3-deo ...
Electron paramagnetic resonance studies of Hg1-xMnxTe1-ySey
(Solid State Communications, 2002)
Electron paramagnetic resonance (EPR) spectra have been measured in diluted magnetic semiconductor Hg1-xMnxTe1-ySey with y = 0.01, x = 0.01, 0.03, 0.05, 0.14 in the temperature range 20-290 K. The influence of various ...
Quantum mechanical rotations, information transfer and decoherence in the converter limit of parametric processes
(Journal of Optics. B: Quantum and Semiclassical Optics, 2002)
In classical three-wave interaction there is a regime where only the phases move but no energy is exchanged. This is strictly valid for classical trajectories with sharp amplitudes and phases. Quantum mechanically, such a ...
Formation and behaviour of low-temperature melting peak of quenched and annealed isotactic polypropylene
(Polymer International, 2002)
The process of low-melting point (LMP) alpha-phase formation in a quenched and annealed isotactic polypropylene (iPP) was studied by means of differential scanning calorimetry. The influence of preparation conditions ...
Rainbows with a tilted LT 111 GT Si very thin crystal
(Physics Letters A, 2002)
The angular distributions of protons channeled in a tilted (111) Si very thin crystal together with the corresponding rainbow patterns are considered. The proton energy is 10 MeV while the crystal thickness is 121.1 nm, ...
Radiative decay of the one-dimensional large acoustic polaron
(Physics Letters A, 2002)
Finite temperature dynamics and stability of the adiabatic large acoustic polaron in one-dimensional systems have been examined by means of the perturbation method based upon the inverse scattering transform. Polaron ...
