Out-of-plane vibrations of shear deformable continuous horizontally curved thin-walled beams
(Academic Press Ltd-elsevier Science Ltd, 2000-10)
This paper presents numerical study about the influence of the shear flexibility, due to either bending and warping, on the out-of-plane free vibration of continuous horizontally curved thin-walled beams with both open and ...
Photoluminescence of bulks and thin films of Eu3+-doped organic/inorganic hybrids
(Elsevier B.V. Sa, 2008-02-28)
Organic-inorganic hybrids formed by polyether-based chains grafted to both ends to a siliceous backbone through urea cross-linkages (-NHC=O)NH-), named di-ureasil, have been used as host for incorporation of Eu3+ in the ...

Problems related to the employment of thin uranium films as neutron dosimeters
(1995-12-01)
Thin uranium films built on muscovite mica basis and obsidian samples having known ages were irradiated with thermal neutrons at the IPEN/CNEN reactor, São Paulo. Comparing thin film performance with the obsidian one, it ...

DQM for vibration analysis of composite thin-walled curved beams
(Academic Press Ltd - Elsevier Science Ltd, 2001-09)
Thin-walled curved beams are extensively used in engineering applications when requirements of weight saving are of primary importance. This is especially true when composite materials are used. For the analysis of isotropic ...
Durango apatite fission-track dating using length-based age corrections and neutron fluence measurements by natural thorium thin films and natural U-doped glasses calibrated through natural uranium thin films
(Elsevier B.V., 2002-08-01)
In this work, we present an approach for neutron fluence measurements based on natural thorium thin films and natural uranium-doped glasses calibrated through natural uranium thin films to be used for dating with the ...
