The role of surface defects in HOPG on the electrochemical and physical deposition of Ag
(Journal of the Serbian Chemical Society, 1999)
The role of defects on a substrate surface during the initial stages of nucleation and growth of Ag deposited electrochemically and physically on highly oriented pyrolytic graphite (HOPG) has been observed ex situ by ...
Classification of the asphalts and their source rock from the Dead Sea Basin (Israel): the asphaltene/kerogen vanadyl porphyrins
(Journal of the Serbian Chemical Society, 1998)
The asphaltenes of the asphalts from the Dead Sea Basin were examined for the presence of vanadyl porphyrins. These examinations demonstrated that the asphalts fall into two broad class types, one having a relatively high ...
Loss of lifetime due to radiation exposure averaging problems
(Health Physics, 1997)
A new method is presented for assessing a years of life lost (YLL) due to stochastic effects caused by the exposure to ionizing radiation, The widely accepted method from the literature uses a ratio of means of two quantities, ...
Towards the definition of the optimum height of voluminous cylindrical sources in gamma-ray spectroscopy
(Applied Radiation and Isotopes, 1999)
We show that for cylindrical voluminous sources in gamma-ray spectroscopy the relative error of the spectral intensity of a low-energy spectral line, as the height of the source increases, saturates faster than the spectral ...
Vibrational structure of the B-X system of isotopic AgO molecules
(Spectroscopy Letters, 1999)
Spectra of (AgO)-Ag-107-O-18 and (AgO)-Ag-107-O-16 molecules have been obtained in a low-pressure are in oxygen atmosphere, and recorded with medium dispersion. Vibrational assignments for the bands of B(2)Pi-X(2)Pi system ...
Detuned primary RF coupling system for variable frequency cyclotrons
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 1998)
A new concept of impedance matching for an RF amplifier coupled to a cyclotron cavity, named detuned primary coupling, is proposed. It does not require the motion of the coupling loop in vacuum and the matching for different ...
Ray analysis of electron cyclotron waves propagating in dissipative thermal plasmas
(Europhysics Letters / EPL, 1996)
The ray tracing in a weakly dissipative thermal plasma, in particular, near the electron cyclotron resonance, is investigated. Numerical results obtained by using a self-consistent new ray tracing approach where the local ...
The libration limits of the elastic pendulum
(American Journal of Physics, 1996)
The motion of the elastic pendulum is ruled by coupling between the pendulum mode and the harmonic oscillator mode. The bob of the pendulum executes trajectories in a domain of the vertical plane, the shape and size of ...
Estimate of radio-silver release from Chernobyl
(Journal of Environmental Radioactivity, 1997)
Precipitation of radiation belt electrons by magnetospherically reflected whistlers
(Journal of Geophysical Research - Space Physics, 1998)
We use a test particle simulation model based on gyro-averaged equations of motion to study the influence of oblique magnetospherically reflected (MR) whistlers on the near-loss-cone distribution function of radiation belt ...
