Feminismo, nacionalismo, e a luta pelo significado do adé no Candomblé: ou, como Edison Carneiro e Ruth Landes inverteram o curso da história

Throughout the 1930's and 40's, Edison Carneiro, Arthur Ramos and Ruth Landes have met in candomble, and their dialogues- sometimes antagonistic, sometimes lovingly - changed this religion. Carneiro used Candomble as a symbol of the northeast; Ramos used it as symbol of Brazil; and Landes, as a symbol of international feminism. The debate on the meaning of Candomble was not merely academic, and it established a new gender pattern in Bahian temples leadership. Opposing to conventional history, Candomble - a religion that gave equal space for male and female priests in the 1930's - became for the first time in the decades following the meeting between Ramos, Carneiro and Landes a matriarchate. In terms of theoretical and transcultural matters, this case shows that imagining communities - including nation-state - is a transnational process. National identity results not only from the interaction between groups of nations, but also from the dispute between overlapping communities on the authority of defining certain shared symbols - as the ade priest, the homosexual. This interaction can change human lives as well as the course of history.Durante os anos de 1930 e 1940, Edison Carneiro, Arthur Ramos e Ruth Landes se encontraram no Candomblé, e por meio do seu diálogo - às vezes antagônico, às vezes amoroso -, transformaram essa religião. Carneiro empregou o Candomblé como um símbolo do Nordeste, Ramos o empregou como um símbolo do Brasil, e Landes, como um símbolo do feminismo internacional. O debate sobre o significado do Candomblé não foi meramente acadêmico, mas estabeleceu um novo padrão de gênero na liderança dos templos da Bahia. Ao contrário da história convencional, o Candomblé, uma religião que dava espaço igual a sacerdotes masculinos e femininos nos anos de 1930, se transformou, pela primeira vez nas décadas depois do encontro de Ramos, Carneiro e Landes, num matriarcado. No plano teórico e transcultural, este caso mostra que a imaginação das comunidades - inclusive a do Estado-nação - é um processo transnacional. A identidade nacional resulta não apenas da interação entre famílias de nações, mas também da luta entre comunidades superpostas pela autoridade de definir certos símbolos compartilhados - como o sacerdote adé, o homossexual. Esta interação pode mudar as vidas humanas e mesmo o curso da história

(Co)isotropic Pairs in Poisson and Presymplectic Vector Spaces

We give two equivalent sets of invariants which classify pairs of coisotropic subspaces of finite-dimensional Poisson vector spaces. For this it is convenient to dualize; we work with pairs of isotropic subspaces of presymplectic vector spaces. We identify ten elementary types which are the building blocks of such pairs, and we write down a matrix, invertible over Z, which takes one 10-tuple of invariants to the other

Platinum-group elements, S, Se and Cu in highly depleted abyssal peridotites from the Mid-Atlantic Ocean Ridge (ODP Hole 1274A): Influence of hydrothermal and magmatic processes

Highly depleted harzburgites and dunites were recovered from ODP Hole 1274A, near the intersection between the Mid-Atlantic Ocean Ridge and the 15°20′N Fracture Zone. In addition to high degrees of partial melting, these peridotites underwent multiple episodes of melt-rock reaction and intense serpentinization and seawater alteration close to the seafloor. Low concentrations of Se, Cu and platinum-group elements (PGE) in harzburgites drilled at around 35-85 m below seafloor are consistent with the consumption of mantle sulfides after high degrees (>15-20 %) of partial melting and redistribution of chalcophile and siderophile elements into PGE-rich residual microphases. Higher concentrations of Cu, Se, Ru, Rh and Pd in harzburgites from the uppermost and lowest cores testify to late reaction with a sulfide melt. Dunites were formed by percolation of silica- and sulfur-undersaturated melts into low-Se harzburgites. Platinum-group and chalcophile elements were not mobilized during dunite formation and mostly preserve the signature of precursor harzburgites, except for higher Ru and lower Pt contents caused by precipitation and removal of platinum-group minerals. During serpentinization at low temperature (<250 °C) and reducing conditions, mantle sulfides experienced desulfurization to S-poor sulfides (mainly heazlewoodite) and awaruite. Contrary to Se and Cu, sulfur does not record the magmatic evolution of peridotites but was mostly added in hydrothermal sulfides and sulfate from seawater. Platinum-group elements were unaffected by post-magmatic low-temperature processes, except Pt and Pd that may have been slightly remobilized during oxidative seawater alteration

Multiple Regression Analysis in the Development of NiFe Cells as Energy Storage Solutions for Intermittent Power Sources Such as Wind or Solar

Multiple regression analysis was used to investigate the effect of bismuth sulphide and iron sulphide as anode additives for NiFe cells. With this in mind, in-house made Fe/FeS/Bi2S3 based electrodes were cycled against commercially available nickel electrodes. A simplex centroid design was used to investigate the combined effects of any of the aforementioned additives on cell performance. The manuscript ends with an initial look at electrolyte systems as a means to further improve the performance of our cells. Finally, our findings support the idea that HS- ions improve the overall performance of NiFe cells

Sulfide melts and long-term low seismic wavespeeds in lithospheric and asthenospheric mantle

Some studies of lithospheric and asthenospheric seismic structure, report mantle velocities as low as ∼4% below the reference models used. While these low wavespeeds may be attributed to thermal effects in tectonically young or actively volcanic regions, in older, tectonically stable regions low velocity anomalies apparently persist even past the decay time of any thermal perturbation, rendering such a mechanism implausible. Low volume melts can also reduce wavespeeds, but their buoyancy should drain them upward away from source regions, preventing significant accumulation if they are able to segregate. Sulfide, ubiquitous as inclusions in lithospheric mantle xenoliths, forms dense, non-segregating melts at temperatures and volatile fugacities characteristic of even old lithospheric mantle. We show that 1–5 volume percent sulfide melts can act to permanently create reductions up to 5.5% in seismic wavespeeds in areas of the lithosphere and the asthenosphere disturbed by prior melting events that carry and concentrate sulfide
