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

Burn wood influence on outdoor air quality in a small village: Foros de Arrão, Portugal

One Plus Sequential Air Sampler—Partisol was placed in a small village (Foros de Arrão) in central Portugal to collect PM10 (particles with an aerodynamic diameter below 10 μm), during the winter period for 3 months (December 2009–March 2010). Particles masses were gravimetrically determined and the filters were analyzed by instrumental neutron activation analysis to assess their chemical composition. The water-soluble ion compositions of the collected particles were determined by Ion-exchange Chromatography. Principal component analysis was applied to the data set of chemical elements and soluble ions to assess the main sources of the air pollutants. The use of both analytical techniques provided information about elemental solubility, such as for potassium, which was important to differentiate sources.

Development of an in situ penetration test for the uptake of preservatives in applied wood

This paper concerns the study of biocides application in old timber structures of maritime pine (Pinus pinaster Ail.), previously impregnated with other products. A method was developed in laboratory to determine in situ the penetration depth of a product applied superficially. As initial treatment, three traditional products for sawn timber for buildings were used and, for new treatments, two newer, more environmentally benign products were used. Their ability to penetrate the pre-treated surfaces was evaluated after 1, 2 and 3 applications at 24 hours intervals and the results obtained are presented. Finally, the applicability of the developed test to the in-situ evaluation of timber structures is also discussed.

Comparison of Py-GC/FID and Wet Chemistry Analysis for Lignin Determination in Wood and Pulps from Eucalyptus globulus

The kraft pulps produced from heartwood and sapwood of Eucalyptus globulus at 130 degrees C, 150 degrees C, and 170 degrees C were characterized by wet chemistry (total lignin as sum of Klason and soluble lignin fractions) and pyrolysis (total lignin denoted as py-lignin). The total lignin content obtained with both methods was similar. In the course of delignification, the py-lignin values were higher (by 2 to 5%) compared to Klason values, which is in line with the importance of soluble lignin for total lignin determination. Pyrolysis analysis presents advantages over wet chemical procedures, and it can be applied to wood and pulps to determine lignin contents at different stages of the delignification process. The py-lignin values were used for kinetic modelling of delignification, with very high predictive value and results similar to those of modelling using wet chemical determinations.

Consolidating preservative-treated wood: Combined mechanical performance of boron and polymeric products in wood degraded by Coniophora puteana

When timber elements in heritage buildings are moderately degraded by fungi and assuming underlying moisture problems have been solved, two actions can be taken: i) use a biocide to stop fungal activity; ii) consolidate the degraded elements so that the timber keeps on fulfilling its structural and decorative functions. The aim of this work is to investigate the mechanical performance of maritime pine wood degraded by fungi after being treated with a biocide followed by impregnation with a polymer product. Three commercially available products were used: a boron water-based biocide, an acrylic consolidant and an epoxy-based consolidant. Treated and consolidated specimens were subjected to mechanical tests: axial compression test (NP 618), static surface hardness (ISO 3350) and bending test (NP 619). Sets of replicates were subjected to an evaporation ageing test (EN 73) after application of the products and also tested for mechanical behaviour. An increase in mechanical strength was observed for both consolidants with no significant influence from the previous use of biocide product. The specimens subjected to ageing showed a slightly better general mechanical performance.

Reactivity of syringyl and guaiacyl lignin units and delignification kinetics in the kraft pulping of eucalyptus globulus wood using Py-Gc-Ms/FID

Eucalyptus globulus sapwood and heartwood showed no differences in lignin content (23.0% vs. 23.7%) and composition: syringyl-lignin (17.9% vs. 18.0%) and guaiacyl-lignin (4.8% vs. 5.2%). Delignification kinetics of S- and G-units in heartwood and sapwood was investigated by Py-GC–MS/FID at 130, 150 and 170 °C and modeled as double first-order reactions. Reactivity differences between S and G-units were small during the main pulping phase and the higher reactivity of S over G units was better expressed in the later pulping stage. The residual lignin composition in pulps was different from wood or from samples in the initial delignification stages, with more G and H-units. S/G ratio ranged from 3 to 4.5 when pulp residual lignin was higher than 10%, decreasing rapidly to less than 1. The S/H was initially around 20 (until 15% residual lignin), decreasing to 4 when residual lignin was about 3%.

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.
