The Chemical Evolution of the Milky Way
, 1999 The field of chemical evolution modeling of the Galaxy is experiencing in the last years a phase of high activity and important achievements. There are, however, several open questions which still need to be answered. In this review I summarize what have

, 2005 We compile a sample of Sun-like stars with accurate effective temperatures, metallicities and colours (from the UV to the near-IR). A crucial improvement is that the effective temperature scale of the stars has recently been established as both accurate ...

Metal Production in Galaxy Clusters: The Non-Galactic Component
, 2010 The metallicity in galaxy clusters is expected to originate from the stars in galaxies, with a population dominated by high mass stars likely being the most important stellar component, especially in rich clusters. We examine the relationship between the

Galaxy Ecosystems: gas contents, inflows and outflows [PDF]
, 2015 We use a set of observational data for galaxy cold gas mass fraction and gas phase metallicity to constrain the content, inflow and outflow of gas in central galaxies hosted by halos with masses between $10^{11} M_{\odot}$ to $10^{12} M_{\odot}$. The gas

, 2016 The quasar Q0918+1636 (z=3.07) has an intervening high-metallicity Damped Lyman-alpha Absorber (DLA) along the line of sight, at a redshift of z=2.58. The DLA is located at a large impact parameter of 16.2 kpc, and has an almost solar metallicity.

Accurate fundamental parameters for Lower Main Sequence Stars
, 2006 We derive an empirical effective temperature and bolometric luminosity calibration for G and K dwarfs, by applying our own implementation of the InfraRed Flux Method to multi-band photometry.

Vértices, 2012 Based on Portinari’s paintings “Dead Child” and “Retirantes”, this paper presents some considerations on drought conditions in the Brazilian Northeast. The study discusses the idea that works of art often draw attention to issues that are not yet fully ...

Modernismo e tradição na arte religiosa - a querela da Pampulha
Locus, 1999 A querela gerada pela reação de setores do clero, intelectualidade e população contra a Igreja de São Francisco de Assis da Pampulha, de Oscar Niemeyer e seus murais, de Cândido Portinari, nas décadas de 1940-50 é entendida aqui como paradgmática das ...

Estudos Ibero-Americanos, 2006 O interesse pela pintura mural suscitou várias tomadas de posição no século XX, dentre elas, a defesa da difusão em ampla escala de imagens eivadas do compromisso do artista para com o próprio tempo e o próprio povo. No conjunto dos “ciclos econômicos”, Portinari demonstra que é possível “narrar uma história” sem aderir à versão oficial, apresentando ...
