Study of Er3+ fluorescence on tellurite glasses containing Ag nanoparticles
(2011-04-12)
Optical characteristics of tellurite glasses containing silver nanoparticles (NPs) and the influence on the emission spectrum of Er 3+ ions were studied. The transitions 4f ↔ 4f from erbium ions, mainly the 4I13/2 → 4I15/2 ...
Spectroscopic properties of Tm3+ doped fluoroindate glass
(2003-12-01)
Optical absorption and fluorescence were investigated in Tm3+ doped fluoroindate glass. The spectroscopic parameters for transitions in the 4f11 configuration were determined. The fluorescence study revealed the origin of ...
On designing OTA-C graphic-equalizers with MOSFET-triode transconductors
(2001-01-01)
A CMOS audio-equalizer based on a parallel-array of 2nd-order bandpass-sections is presented and realized with triode transconductors. It has a programmable 12db-boost/cut on each of its three decade-bands, easily achieved ...
On the spectrum of rail vibration generated by a passing train
(2017-01-01)
Recent work in rail vibration has investigated methods for estimating track support stiffness from trackside vibration. This vibration, induced by the passage of a train, is mainly due to the load applied by the wheels, ...
Shape resonance spectrum of cytosine-guanine pairs.
(Sociedade Brasileira de FísicaÁguas de Lindóia, 2013)
Single and double strand breaks in DNA can be caused by low-energy electrons, the most abundant secondary products of the interaction of ionizing radiation to the biological matter. Attachment of these electrons to ...
Short-distance part of the interaction of D mesons and nucleons
(2008-12-01)
The short-distance part of the low energy interaction of D-mesons and nucleons is investigated in the context of a quark model. The quark model is based on Coulomb gauge QCD. The model contains a confining Coulomb potential ...
Induced radioisotopes inside the treatment hall with a Linac radiotherapy
(Universidad Autónoma Metropolitana, 2014-04)
When linacs operate above 8 MV an undesirable neutron field is produced whose spectrum
has three main components: the direct spectrum due to those neutrons leaking out from the
linac head, the scattered spectrum due to ...
A 222 Energy Bins Response Matrix fora 6LiI Scintillator BSS system
(Sociedad Mexicana de Irradiación y Dosimetría, 2016-09-28)
A new response matrix was calculated for a Bonner Sphere Spectrometer (BSS) with a 6LiI(Eu) scintillator. We utilized the Monte Carlo N-Particle radiation transport code MCNPX, version 2.7.0, with ENDF/B-VII.0 ...
