Intelectuais e imprensa: a configuração de uma rede hispano-americana no espaço atlântico

Este artigo trata da configuração de uma rede intelectual de dimensão internacional que uniu a América Latina e a Península Ibérica, a partir de meados do século XIX. Objetivamos analisar o papel dos intelectuais e órgãos de imprensa na formação dessa rede e discutir suas idéias e projetos, à luz do contexto político e do debate cultural. Consideramos que a ação dos intelectuais e da imprensa contribuiu para a configuração de um espaço singular de circulação de idéias e de formação de uma opinião pública ibero-americana.

Um sistema de previsão de tempo e de ondas oceânicas para o Atlântico Sul

Um sistema de previsão numérica de tempo e de ondas oceânicas (SPTO) que possa ser operacionalizado no Atlântico Sul é proposto. O SPTO é composto por um modelo atmosférico de área limitada (MAL) e um modelo de ondas de superfície do oceano geradas pelo vento, aplicado em duas versões: uma de malha grossa (MPOMG) e outra de malha fina (MPOMF). O MPOMG abrange uma área de 10(6) km², e tem como finalidade gerar e propagar ondas em regiões remotas à costa brasileira. O MPOMF é aplicado em um domínio 10(4) km² com alta resolução, incorporando irregularidades batimétricas e com as condições iniciais e de fronteiras fomecidas pelo MPOMG. Os modelos utilizam dados de vento à 10 m acima da superfície do oceano. Os arquivos de vento, contendo a evolução espacial e temporais são gerados pelo MAL. Um exemplo de um evento real ocorrido no período de 9 a 11 de agosto de 1988 é apresentado utilizando o acoplamento proposto.

Dinámica del suelo y estoque de carbono después de diez años de la restauración de tierras degradadas usando especies arbóreas del bosque atlántico

Brazil's Atlantic Forest ecosystem has been greatly affected by land use changes, with only 11.26% of its original vegetation cover remaining. Currently, Atlantic Forest restoration is receiving increasing attention because of its potential for carbon sequestration and the important role of soil carbon in the global carbon balance. Soil organic matter is also essential for physical, chemical and biological components of soil fertility and forest sustainability. This study evaluated the potential for soil recovery in contrasting restoration models using indigenous Atlantic Forest tree species ten years after their establishment. The study site is located in Botucatu municipality, São Paulo State-Brazil, in a loamy dystrophic Red-Yellow Argisol site (Typic Hapludult). Four treatments were compared: i) Control (Spontaneous Restoration); ii) Low Diversity (five fast-growing tree species established by direct seeding); iii) High Diversity (mixed plantings of 41 species established with seedlings) and; iv) Native Forest (well conserved neighboring forest fragment). The following soil properties were evaluated: (1) physical-texture, density and porosity; (2) chemical-C, N, P, S, K, Ca, Mg, Al and pH; (3) biological-microbial biomass. Litter nutrient concentrations (P, S, K, Ca and Mg) and C and N litter stocks were determined. Within ten years the litter C and N stocks of the Low Diversity treatment area were higher than Control and similar to those in both the High Diversity treatment and the Native Forest. Soil C stocks increased through time for both models and in the Control plots, but remained highest in the Native Forest. The methods of restoration were shown to have different effects on soil dynamics, mainly on chemical properties. These results show that, at least in the short-term, changes in soil properties are more rapid in a less complex system like the Low Diversity model than in the a High Species Diversity model. For both mixed plantation systems, carbon soil cycling can be reestablished, resulting in increases in carbon stocks in both soil and litter.

Entre o atlântico e a costa: confluência de rotas mercantis num porto periférico da América portuguesa (Santos, 1808-1822)

This paper has approached the coastal and Atlantic characters of such commercial activity in the port of Santos between 1808 and 1822 and the contradictions arising of this double condition, which is unique in the Southern coast of Portuguese America. This discussion was based on data collected in importation and exportation maps produced by customs of Santos to the Royal Board of Trade.

Mapeamento da ilha da Trindade, Atlântico Sul

The area chosen for this study is the island of Trinidade, which is located 1167 km off the Brazilian coast, in parallel Victory at 20 ° 30'S and 29 º 19'W, being the most easterly point of our continent. The isolation of oceanic island of Trinidade leaves no noticeable that she is part of a large submarine volcanic chain oriented east-west lineament known as Vitória- Trindade. Along with the island of Martin Vaz, who is Federal Territory is administered by the Navy of Brazil. Both correspond to Source alkaline volcanic islands. The area of the island of Trinidad has approximately 10 km2. Geologically consisting ankaratritic spills, spills tannbuschiticos, volcanic tuff spills analcite-ankaratrite, phonolite spills, spills nefelinite, pyroclastics, spills grazinite, tinguaitos, olivine-analcitito, calcarenite dunes and wind according to Almeida (1961). The island has its base on the ocean floor, at 5,800 m depth. It is the only place still recognizes preserved volcanic necks and plugs, as well as remnants of a volcano in Brazil. Magmatism occurred here a sodium alkali-silica subsaturated where his wrist was last 50,000 years according to Almeida (1961). It is a place with restricted access due to their distance from the coast, his contribution and hard to be an exclusive area of the Navy. On the island with peaks occur up to 620 meters high, and its rugged mountainous terrain and difficult access to very specific points, as the peak of Desire, peak Fazendinha, Monument and other points on the island. Because of its location far from the coast, its small infrastructure, difficulty of landing and restricted access by sea, the island of Trinidad offers no possibility of tourism, being a military outpost, and scientific basis of great importance, which conduct research in area of marine biology, oceanography, geology and others

Do vento ao vapor em mares já antes navegados: a companhia de navegação La Veloce e o transporte de emigrantes pelo Atlântico

In the final decades of the nineteenth century, the growth of Italian emigration was constituted in a secure source of income for the shipping companies that operated in the Atlantic and played a major role in financing the replacement of old sailboats by modern steamers. Based on reports and balance exercises financial, besides newspapers related to mercantile marine, this article aims to present some results of the research about the importance of Italians emigrants’ transporting to the shipping company La Veloce, showing its economic trajectory and particularities.
