Souza-Cardoso and Boccioni: A Comparison of Similar Movements
No full textABSTRACT Even though he was not affiliated to any of the so-called avant-garde movements that emerged during his brief lifetime, Souza-Cardoso's vast and prolific artistic work managed to relate to all these avant-garde movements, using beauty and grace to create his works. In contrast, Umberto Boccioni, a very diligent painter and sculptor, actively engaged in the avant-garde movements that swept through some areas of Europe like a wild fire, is an entirely futuristic author. I intend to consider the work of these two artists by putting special emphasis on the fact that they both had the same goal -- namely, the dynamics of the human body. Furthermore, I will also take into account their simultaneous convergence and divergence regarding the guidelines of the ultramodern manifesto.</p

The epithet refers to the municipality of Cristalina, where the new species is found. In addition to being well known for the production of gemstones and crystals, Cristalina is also recognised here for inhabiting ‘precious’ plants.</p> <p> <i>Distribution and habitat</i>. <i>Pombalia cristalina</i> is known only from open savannas and campos rupestres around the municipality of Cristalina, Goiás state, central Brazil (<b>Figure 3</b>).</p> <p> <i>Phenology</i>. The species has been collected with flowers and fruits in September and October, with a single flowering record for July.</p> <p> <i>Conservation status</i>. The municipality of Cristalina is situated at the junction of Brazil’s two major highways, which link the largest cities of the country to its capital city, Brasília. This has contributed to much of the growth and urbanisation of the area at the expense of its natural ecosystems. This region is one of the most important centres of production of crystals and gemstones in Brazil (hence the name), and potential environmental effects of this industry are an intense threat to its natural habitats. Personal observations have further indicated that agriculture is a relevant threat; at least two known populations have been drastically reduced and are struggling in cultivated fields of heavily mechanised crops. There is a single occurrence of this species from a small conservation unit. Therefore, according to IUCN (2012) criteria B1a,b(i,iii), <i>Pombalia cristalina</i> is considered Critically Endangered (CR) based on its very limited distribution (EOO, 13,413 km 2) and the continuing decline in the quality of its habitat.</p> <p> <i>Additional specimens examined</i>.

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
Get PDFFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
