Encenação contemporânea o contributo de Fernando Pessoa

De Maeterlinck, Pessoa inspira-se para o “drama estático”, numa primeira fase da sua obra dramática. Mas posteriormente, é peremptório em considerar o teatro do seu par belga como “falhado”, dada a “opressão excessiva do símbolo”. O seu principal modelo foi Shakespeare. A par da criação, Pessoa teorizou largamente sobre a arte teatral (teorizando afinal que o “drama estático” implica obrigatoriamente movimento), confluindo com determinadas estéticas do Modernismo e do chamado pós-Modernismo. Também se fez notar como crítico teatral nas páginas da revista Teatro – Revista de Crítica, fundada em 1913 e que era o local onde se reuniam os intelectuais de então, com o firme propósito de “vir [a] destruir o [teatro] existente”, sendo este o primeiro passo do Modernismo nas artes em Portugal e não na revista Orpheu (1915). A intenção era a de que o “actor artista perfeito” exprimisse pelo drama a soma de todas as suas faculdades de imaginação e expressão, revelando as suas naturezas e necessidades e atingindo uma interpretação inteligível para todos. Deste modo, o homem que afirmava que “nem pensou nunca, nem sentiu, senão dramaticamente”, abre-nos uma vasta cortina para discorrermos sobre o seu contributo para a encenação contemporânea.

Análise técnico-económica do sistema de abastecimento de água ao Hospital Prof. Dr. Fernando da Fonseca

Cada vez mais, a adopção de medidas relacionadas com a conservação de água se tem tornado fundamental nos edifícios públicos e institucionais, devido ao seu alto custo de operação. Além disso, a economia advinda da redução do consumo pode possibilitar não somente o custeio de outros itens necessários ao seu funcionamento, mas também a disponibilização desse volume economizado para o atendimento de novos clientes com a mesma infra-estrutura urbana instalada, contribuindo, assim, para a conservação do meio ambiente, premissa básica do desenvolvimento sustentável de qualquer país. Espera-se que este estudo motive o desenvolvimento de acções similares em edificações desta tipologia e em outros edifícios dedicados a funções específicas

Biodiesel production over lithium modified lime catalysts: activity and deactivation

Biodiesel production by methanolysis of semi-refined rapeseed oil was studied over lime based catalysts. In order to improve the catalysts basicity a commercial CaO material was impregnated with aqueous solution of lithium nitrate (Li/Ca = 03 atomic ratio). The catalysts were calcined at 575 degrees C and 800 degrees C, for 5 h, to remove nitrate ions before reaction. The XRD patterns of the fresh catalysts, including the bare CaO, showed lines ascribable to CaO and Ca(OH)(2). The absence of XRD lines belonging to Li phases confirms the efficient dispersion of Li over CaO. In the tested condition (W-cat/W-oil = 5%; CH3OH/oil = 12 molar ratio) all the fresh catalysts provided similar biodiesel yields (FAME >93% after 4 h) but the bare CaO catalyst was more stable. The activity decay of the Li modified samples can be related to the enhanced, by the higher basicity, calcium diglyceroxide formation during methanolysis which promotes calcium leaching. The calcination temperature for Li modified catalysts plays an important role since encourages the crystals sinterization which appears to improve the catalyst stability. (C) 2013 Elsevier B.V.

Ariel o renovador: a crítica teatral de Fernando Amado como expressão de um ideário de teatro

É objectivo deste artigo explorar a ideia de teatro que os textos de crítica teatral de Fernando Amado encerram ou ajudam a revelar. Para tal, importará dar conta do momento de renovação cénica e actualização cultural, de que a segunda metade dos anos quarenta é expoente, e das relações que o ideário formado por Fernando Amado, Redondo Júnior ou Gino Saviotti, entre outros, pode estabelecer com o que pela Europa Teatral se vai apelidando de teatro moderno.

A Casa da Comédia (1946-1975): de Fernando Amado a Bertolt Brecht

Tomando como ponto de partida o movimento de teatro experimental português do pós-Segunda Guerra Mundial, a presente investigação centra-se no trajecto da Casa da Comédia, fundada por Fernando Amado em 1946, e que retoma a actividade em 1962. Procuramos identificar as ideias de teatro que animam o percurso deste grupo, dar eco da recepção aos seus espectáculos, bem como inserir o seu projecto no âmbito dos esforços de renovação cénica que vão tendo lugar um pouco por toda a Europa.

Preliminary study of synthesis gas production from water electrolysis, using the ELECTROFUEL (R) concept

This paper describes preliminary work on the generation of synthesis gas from water electrolysis using graphite electrodes without the separation of the generated gases. This is an innovative process, that has no similar work been done earlier. Preliminary tests allowed to establish correlations between the applied current to the electrolyser and flow rate and composition of the generated syngas, as well as a characterisation of generated carbon nanoparticles. The obtained syngas can further be used to produce synthetic liquid fuels, for example, methane, methanol or DME (dimethyl ether) in a catalytic reactor, in further stages of a present ongoing project, using the ELECTROFUEL® concept. The main competitive advantage of this project lies in the built-in of an innovative technology product, from RE (renewable energy) power in remote locations, for example, islands, villages in mountains as an alternative for energy storage for mobility constraints.

The key role of coligands in novel ruthenium(II)-cyclopentadienyl bipyridine derivatives: Ranging from non-cytotoxic to highly cytotoxic compounds

A new family of eight ruthenium(II)-cyclopentadienyl bipyridine derivatives, bearing nitrogen, sulfur, phosphorous and carbonyl sigma bonded coligands, has been synthesized. Compounds bearing nitrogen bonded coligands were found to be unstable in aqueous solution, while the others presented appropriate stabilities for the biologic assays and pursued for determination of IC50 values in ovarian (A2780) and breast (MCF7 and MDAMB231) human cancer cell lines. These studies were also carried out for the [5: HSA] and [6: HSA] adducts (HSA = human serum albumin) and a better performance was found for the first case. Spectroscopic, electrochemical studies by cyclic voltammetry and density functional theory calculations allowed us to get some understanding on the electronic flow directions within the molecules and to find a possible clue concerning the structural features of coligands that can activate bipyridyl ligands toward an increased cytotoxic effect. X-ray structure analysis of compound [Ru(eta(5)-C5H5)(bipy)(PPh3)][PF6] (7; bipy = bipyridine) showed crystallization on C2/c space group with two enantiomers of the [Ru(eta(5)-C5H5)(bipy)(PPh3)](+) cation complex in the racemic crystal packing.
