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 ...
Centering of the ion trajectory in the cyclotron
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2002)
In this paper we present the theory of the horizontal motion ions through the acceleration gap in the case of a static magnetic field and time-varying electric field. It also describes the motion of the center of the ion ...
Effect of Cd2+ and Hg2+ on the activity of Na+/K+-ATPase and Mg2+-ATPase adsorbed on polystyrene microtiter plates
(Analytical Biochemistry, 2002)
In the present study a polystyrene microtiter plate was tested as a support material for synaptic plasma membrane (SPM) immobilization by adsorption. The adsorption was carried out by an 18-h incubation at +4degreesC of ...
Evidence based on crystal structures and calculations of a C-H-...pi interaction between an organic moiety and a chelate ring in transition metal complexes
(European Journal of Inorganic Chemistry, 2002)
Structural and computational evidence is given for a special type of C-H(...)pi interaction where the C-H group interacts with the pi-system of a six-membered chelate ring. An investigation of crystal structures shows that ...
Digital gamma-ray spectroscopy based on FPGA technology
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2002)
A digital pulse processing system convenient for high rate gamma-ray spectroscopy with NaI(Tl) detectors has been designed. The new programmable logic device has been used for implementation of dedicated high-speed pulse ...
A generalization of the preset count moving average algorithm for digital rate meters
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2002)
A generalized definition of the preset count moving average algorithm for digital rate meters has been introduced. The algorithm is based on the knowledge of time intervals between successive pulses in random-pulse sequences. ...
Design of the central region in the Gustaf Werner cyclotron at the Uppsala university
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2002)
This paper describes the design of the central region in the Gustaf Werner cyclotron for h = 1, 2 and 3 modes of acceleration. The electric field distribution in the inflector and in the four acceleration gaps has been ...
Production of positron annihilation radiation by cosmic-rays near sea level
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2002)
Production of positron annihilation radiation by cosmic-rays in Al, Fe, Sn and Pb is measured by means of a triggered HPGe detector. The equipment is located in Belgrade, at an absolute height of 125 m a.s.l. The production ...
Electrochemical deposition and characterization of Zn-Co alloys and corrosion protection by electrodeposited epoxy coating on Zn-Co alloy
(Electrochimica Acta, 2002)
Zn-Co alloys electrochemically deposited on steel under various deposition conditions were investigated. The influence of deposition current density, temperature and composition of deposition solution on the phase structure ...
Estimation of thermal contact resistance between the materials of double-layer sample using the laser flash method
(Inverse Problems in Engineering, 2002)
This paper proposes a technique for estimation of thermal contact resistance between two opaque solids. The laser flash method combined with an inverse approach based on the Gauss parameter estimation procedure is used. ...
