The cane sugar is important since the early days in the history of the country, following the discovery of Brazil since the colonial period, therefore, the culture has an important role in the Brazilian economy, being one of the main products. In the 1970s with the advent of the economic crisis, geopolitical and the possibility of depletion of oil, countries dependent on imported fuel, sought new energy alternatives. In Brazil, it was decreed in 1975 the creation of the National Alcohol Program - PROALCOOL, who had several years of rising, the increase of distilleries and marketing of cars powered with ethanol blend. Due to the decrease in the price of oil the importance of the program significantly reduced, returning to peak only in 1979, ie, the second phase of the program. Conceived as one of the vectors of the national response to the crisis in oil prices '70s, the program persisted at times rising in others not reaching for more than three decades. Brazil is the second largest ethanol producer, second only to the U.S., where the raw material comes from corn, which becomes a bottleneck biodiesel production because it competes with food production. New technologies developed to increase ethanol production combined with sustainability and economic viability are being held, the principal is the second generation ethanol, known as cellulosic ethanol, ethanol plus third and fourth generation.

This paper aims to make a Postcolonial Reading of the Gothic novel Dracula, written by Bram Stoker. Most importantly, it is considered how the subaltern is silenced, and that how this silence reflects the characters responsible for the discourse construction in the book. For this purpose, the theories of three important writers of the Post-Colonialism, Edward Said, Homi Bhabha and Gayatri Chakravorty Spivak, were studied, as well as the enlightening ideas of Stephen Arata in The Occidental Tourist: Dracula and the Anxiety of Reverse Colonization. It also verified the construction of Orientalism in Stoker's work, and its constitutively hybrid and transparent characters due the speech manipulation with the ideological filter of the hegemonic power. This manipulation also characterizes the fragmentation in the work, which is an indication, among others, of modernity in Stoker's novel

The effects of spatial competition among colonial marine organisms are often evident in the contact zones between colonies. These effects are especially pronounced when the interaction results in overgrowth or necrosis of one of the competitors. Ascidians, one of the dominant taxonomic groups in subtidal sessile communities, have specialized morula cells that provide a defense against microbial infections. Injuries resulting from interspecific competitive interactions might also act as a stimulus for this defensive mechanism. Therefore, we expected to see the recruitment of morula cells in tissues near competitor contact zones. To test the hypothesis that spatial competition elicits this immune response, we placed colonies of the ascidian Didemnum perlucidum from southeastern Brazil in four different types of competitive situations: (1) overgrowth of the competitor, (2) stand-off interactions, (3) overgrowth by the competitor, and (4) free of competitors. Our results indicate that competitive interactions increase the population of morula cells in contact zones, as more cells were observed in interactions that resulted in the overgrowth of individuals of D. perlucidum, and fewer cells were observed in colonies that were free of competitors. We identified the defensive function of the morula cells by showing the presence of the enzyme phenoloxidase within its vacuoles. Phenoloxidase is a widespread enzyme among animals and plants, and is frequently used in defense by synthesizing toxic quinones from polyphenol substrates. This is the first study to document the presence of morula cells in didemnid ascidians and the mobilization of these cells by spatial competition by heterospecifics, and one of the first studies to identify phenoloxidase activity in morula cells.

Paradigma tradicional de excelência artesanal, com que meios pode a pintura responder à abstração do trabalho e à sua ordenação serial, inerentes à modernização capitalista? O texto presente busca sistematizar os momentos decisivos de um percurso que se estende de Manet (1832-1883) a Rothko (1903-1970). Constitui o capítulo conclusivo de uma investigação sobre a transformação crítica do modo de pintar em modo de fabricação, fundado na superação reflexiva da dicotomia entre trabalho intelectual e corporal, imposta historicamente à sociedade. Atualizada criticamente e assinalando um fecho possível do processo da arte moderna, a pintura de Rothko põe-se como a negação de todo aspecto individual da pintura e de unidade orgânica e monádica da obra. Alcança-se assim o último termo de um processo; termo que assinala o fim do ciclo da autonomia estética como forma ligada à liberdade do sujeito, idealizado como natureza desinteressada. Para o trabalho de resistência contra a aceleração da barbárie é fundamental doravante levar em conta os fatores de heteronomia supraindividuais que, se não logram controlar toda a produção, detêm a hegemonia na esfera da circulação.

Este texto, a ser publicado em duas partes, contém, com pequenas modificações para efeito de edição, extratos da introdução e da conclusão da tese de doutorado A fabricação da pintura: de Manet a Rothko, defendida no Departamento de Filosofia, FFLCH-USP, sob orientação do Prof. Dr. Paulo Arantes em 2000. Opondo-se à visão hegemônica propagada pelas correntes formalistas, cujas motivações ideológicas pretende explicitar, o ensaio salienta a valorização dos processos produtivos frente às obras acabadas como característica fundamental da arte moderna, característica por meio da qual os artistas resistem ao progresso da modernização capitalista

A Conferência Rio+20 mobiliza a comunidade global em 2012 para participar de um desafiador debate sobre a realidade ambiental global e modus operandi existente quanto à temática ampla e genérica do desenvolvimento e do ambiente. Um dos temas estruturantes desta reunião é a transição para uma economia verde no contexto do desenvolvimento sustentável e da erradicação da pobreza. O tema da Governança Ambiental Global um dos carros chefe do debate na Rio+20, no intuito de promover e acelerar a transição rumo a sociedades sustentáveis, configura a construção muitas vezes, de forma controversa, das condições para a definição de novos espaços institucionais e processos decisórios compartilhados. Este artigo propõe aos leitores uma reflexão para discutir que tipo de sustentabilidade está por trás da economia verde, a sua aplicabilidade e o que deva ser priorizada na discussão de governança ambiental. Isto se explica na medida em que existe a necessidade de mudar os mecanismos de utilização dos recursos, profundamente injustos, e que impedem avanços nos processos decisórios, pois as decisões de poucos tem configurado uma lógica perversa de expropriação de recursos naturais e não resolução da exclusão social.

Portable system of energy dispersive X-ray fluorescence was used to determine the elemental composition of 68 pottery fragments from Sambaqui do Bacanga, an archeological site in Sao Luis, Maranhao, Brazil. This site was occupied from 6600 BP until 900 BP. By determining the element chemical composition of those fragments, it was possible to verify the existence of engobe in 43 pottery fragments. Obtained from two-dimensional graphs and hierarchical cluster analysis performed in fragments of stratigraphies from surface and 113-cm level, and 10 to 20, 132 and 144-cm level, it was possible to group these fragments in five distinct groups, according to their stratigraphies. The results of data grouping (two-dimensional graphics) are in agreement with hierarchical cluster analysis by Ward method. Copyright (C) 2011 John Wiley & Sons, Ltd.

The Brazilian market in the XIX century: an approach through the cabotage commerce. The maritime commerce consisted of the main way of circulation of the goods between the Brazilian provinces until the second half of century XIX. Although the relatively big importance of the flows of commerce with the exterior, we note significant exchange of goods by sea between the Brazilian regions since the colonial period. A part of these exchanges derived from products destined in last instance to the foreigner or imported of the exterior. However, another part elapsed of national goods that had not arrived at be exported to the international market. Many goods for the colonial and imperial consumption had circulated by the Brazilian coasts in expressive sums. From the information raised for the imperial period, especially the decades of 1860 and 1870, we verify that most of the goods commercialized between the provinces consisted of national products destined to the internal consumption.

Este artigo analisa a moderna retomada do debate do cálculo econômico socialista. Mostramos como as modificações no cinturão protetor do programa de pesquisa neoclássico possibilitaram a discussão do problema dos incentivos sob informação assimétrica nas novas propostas de socialismo de mercado. Nessas propostas, o problema do conhecimento tal como desenvolvido por Hayek no debate original será interpretado como um problema de informação. Defendemos a tese de que, embora os modelos tenham sido criticados por economistas afiliados a escola da escolha pública, as novas propostas de socialismo de mercado e seus críticos sofrem dos mesmos problemas apontados por Hayek no debate original.

O texto versa sobre o papel dos mestres-construtores na produção da arquitetura nas vilas e cidades coloniais brasileiras, focalizando o sistema de empreitada em etapas e o papel dos riscos e traças na concepção, execução, louvação e prestação de contas das edificações. Questiona a ideia de autoria única, apontando atores e assinaturas múltiplas. Analisa os conhecimentos necessários, especialmente relacionados à geometria prática, discutindo a relação dialética entre teoria e prática, e as fronteiras tênues entre erudição e costume.
