Numerical simulation of photothermal effects in solids with inhomogeneous thermal properties
(Journal of Physics. D: Applied Physics, 1999)
A numerical simulation procedure for the calculation of surface temperature in thermally inhomogeneous solids induced by a harmonically modulated external heat source is presented. The procedure is based on the separation ...
On the general-order kinetics of the thermoluminescence glow peak and the calculation of parameters from glow curves
(Journal of Luminescence, 1998)
It has been shown by a new approach that the equation which describes general-order kinetics is an interpolating function between analogous equations for first- and second-order kinetics. A new method for calculation of ...
Pressure effects on CO2-laser coincidences with ethene and ammonia investigated by photoacoustic detection
(Infrared Physics and Technology, 1998)
Carbon dioxide laser coincidences were investigated by photoacoustic detection at laser lines 10P(28) and 9P(28) with ethene and at 10P(20) and 10P(16) with ammonia. The intensities of coincidences were measured as a ...
Initial clinical experience with PerDUCER (R) device: Promising new tool in the diagnosis and treatment of pericardial disease
(Clinical Cardiology, 1999)
Background: The idea to enter the normal pericardial sac safely was unrealistic until recently. The development of a novel instrument (PerDUCER(R) pericardial access device) for percutaneous access to the pericardium could ...
Comparison of TL spectra of co-doped dosimetric materials
(Radiation Protection Dosimetry, 1999)
Wavelength resolved spectra of the dosimetric materials CaSO4 and MgB4O7 with the rare earth (RE) ions Dy and Tm are presented. The study of co-doped samples provides, within a single sample, unequivocal evidence of a glow ...
The new recurrence relation for magic numbers and some of its possible implications
(Journal of Physics. G: Nuclear and Particle Physics, 1999)
We discuss the possible implications of the peculiar recurrence relation which we demonstrate to hold for the series of empirical magic numbers. These include thc space-wise shell structure of the nucleus in both the proton ...
The use of SSNTDS in the retrospective assessment of radon exposure in high radon rural communities in Yugoslavia
(Radiation Measurements, 1999)
A description is given of the field application of a technique using CR-39 and LR 115 detectors to determine alpha recoil implanted Po-210 surface activity on domestic glass artefacts in dwellings. These investigations ...
Ternary events measured with CR-39 in the U-238+Au-197 reaction at 15 MeV/nucleon
(Radiation Measurements, 1999)
We report the study of the reaction 15 MeV/nucleon U-238 + (197)AU, in, which up to 7 final heavy fragments have been detected, using a CR-39 plastic nuclear track detector. The measured multiplicity distributions indicate ...
Corrosion behaviour of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Ni alloy
(Electrochimica Acta, 1999)
The corrosion behaviour and thermal stability of epoxy coatings electrodeposited on steel: phosphatised steel and steel previously modified by electrodeposited Zn-Ni alloy was investigated during exposure to 3% NaCl. The ...
Mechanochemical treatment of alpha-Fe2O3 powder in air atmosphere
(Materials Science and Engineering A: Structural Materials Properties Microstructure and Processing, 1998)
Powder of alpha-Fe2O3 was mechanochemically treated in a planetary ball mill in an air atmosphere. Structural changes were followed by X-ray diffraction analysis, magnetization measurements and differential scanning ...
