Concentration measurements of Be-7 and Cs-137 in ground level air in the Belgrade city area
(Environment International, 1999)
Concentrations of Be-7 and Cs-137 in ground level air in the city area (Belgrade, central Serbia) were determined in the period from 1991-1996, The average monthly concentrations of Be-7 in ground level air were in the ...
Fitting the glow curve and calculating TL parameters
(Journal of Physics. D: Applied Physics, 1999)
A new glow curve fitting method using the Gauss-Lorentz asymmetric function is suggested. By calculating the thermoluminescence (TL) parameters it is shown that this is compatible with a general-order kinetics model. The ...
Beam orbit simulation in the central region of the RIKEN AVF cyclotron
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 1999)
This paper describes the modification design of the central region for h = 2 mode of acceleration in the RIKEN AVF cyclotron. we made a small modification to the electrode shape in the central region for optimization of ...
Formation of celsian from mechanically activated BaCO3-Al2O3-SiO2 mixtures
(Journal of Alloys and Compounds, 1999)
A ternary mixture BaCO3-Al2O3-SiO2 was mechanically activated for different lengths of time. Chemical composition of the mixture corresponded to BaAl2Si2O8-BAS As a function of activation time, reaction course was followed ...
Self-association and association of tri-n-butyl phosphate (TBP) in different diluents
(Journal of the Serbian Chemical Society, 1999)
The interact ion of tri-n-butyl phosphate (TBP) with diluents and its self-association have been investigated. The corresponding equilibrium constants were determined and used to calculate the concentration of TBP monomer. ...
Point of zero charge and intrinsic equilibrium constants of activated carbon cloth
(Carbon, 1999)
Surface propel-ties of cellulose-based activated carbon cloth were investigated. The point of zero charge was determined by batch equilibrium method. Surface charge densities were obtained from potentiometric titrations. ...
Phonons in ultrathin layered structures
(Journal of Physics and Chemistry of Solids, 1999)
Phonon subsystem of ultrathin films was analysed using Greens functions of the displacement-displacement type, including quantum size effect and effect of boundaries onto Hamiltonian parameters. Diagonal components of ...
A PC-based radiation monitor
(Instruments and Experimental Techniques, 1999)
A low-cost high-precision system for monitoring the radioactivity level has been developed on the basis of a personal computer using the modern concept of virtual instrumentation. The proposed device has certain advantages ...
Electrochemical characteristics of binary silver alloys in alkaline solution
(Journal of Power Sources, 1999)
The electrochemical features, electrode capacity and corrosion stability, of silver alloys with Tl, Pb, P,Sb, Ge and In have been investigated. Compared to silver some silver alloys showed improved silver oxide formation ...
Simulation of ion trajectories in a quadrupole ion trap: a comparison of three simulation programs
(Journal of Mass Spectrometry, 1999)
An attempt has been made to compare the performance, design and operation of three simulators, ISIS, ITSIM and SIMION-3D, when applied to the calculation of ion trajectories in a quadrupole ion trap. For the simulation of ...
