Re-análise de gigantes vermelhas no aglomerado globular NGC 6522
(Universidade de São Paulo. Instituto de Astronomia, Geofísica e Ciências AtmosféricasSão Paulo, 2014)
O aglomerado globular do bojo NGC 6522 é moderadamente pobre em metais ([Fe/H]=-1.0). A análise de 8 estrelas desse aglomerado por Barbuy et al. (2009, A&A, 507, 405) revelou excesso de Bário em algumas dessas estrelas. ...
Multiple particle and cluster emissions from Zr following intermediate energies photo absorption
(2007-12-01)
A new approach based on a N-a cluster photoabsorption model is proposed for the understanding of the puzzling steady increase behavior of the 90Zr (e, α) yield measured at the National Bureau of Standards (NBS) within the ...
Preparation and melting of Zr-1.0Nb alloy
(2016-01-01)
Zirconium alloys have many applications in industry in services too harsh for stainless steels, nickel alloys or where a noteworthy improvement in service life may be achieved, by choosing zirconium alloys instead of other ...

Ab-initio and CVM calculations on the metastable fcc, hcp, and bcc Pb-Bi-Te and Pb-Bi-Po ternary systems.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
A molten Pb Bi alloy will be used as coolant in MYRRHA (Multi-purpose hybrid research reactor for high-tech applications), a prototype of an accelerator-driven nuclear fission reactor (“generation IV reactor”) that will ...
Zinc abundances in galactic bulge stars
(International Astronomical UnionFlorianópolis, 2013)
Zinc is overabundant in metal-poor stars (Cayrel et
al. 2004), being partially produced by neutron addition.
It decreases with increasing metallicity, similarly
to alpha-elements. In order to trace its abundance,
the ...
