Simulation of defects in aluminium castings using CAD models of flaws and real X-ray images
(BRITISH INST NON-DESTRUCTIVE TESTING, 2005)
In order to evaluate the sensitivity of defect inspection systems, it is convenient to examine simulated data. This gives the possibility to tune the parameters of the inspection method and to test the performance of the ...
Histomorphometry of sexually immature albino rat testis after X ray-irradiation
(Interciencia, 1997-03-01)
A A morphometric study was conducted of sexually immature albino rat testes which were exposed to a localized single. X-ray dose of 154.00 mC/Kg.The rats were killed at the ages of 25, 30, 35, 45, 60, 90 and 120 days. Their ...
Distance limits on the bright X-ray emission toward the Galactic center: Evidence for a very hot interstellar medium in the Galactic X-ray bulge
(UNIV CHICAGO PRESS, 2000-12-10)
Observations of the diffuse X-ray background at energies similar to3/4 and 1.5 keV show a large region of enhanced emission around the Galactic center. The origin of this X-ray enhancement is not known, but the best ...
The reference value for blood potassium in inhabitants of Brazil by EDXRF technique

Methanol oxidation on PtRu/C electrocatalysts prepared by a microemulsion method
(2007-12-01)
PtRu/C nanocatalysts were prepared by a microemulsion method using different values of water/surfactant molar ratio in order to get different particle sizes. Crystallite sizes and structural properties were determined by ...
The investigation of α→β phase transition in poly(vinylidene fluoride) (PVDF)
(2005-12-01)
The phase transition from the non-polar α-phase to the polar β-phase of poly(vinylidene fluoride) (PVDF) has been investigated using micro-Raman spectroscopy, which is advantageous for being a non-destructive technique. ...
