The trombone as portrayed in Portuguese iconography during the sixteenth and early seventeenth centuries
No full textThis article studies eleven sixteenth and seventeenth century iconographical sources depicting slide brass instruments, by both Portuguese and foreign artists active in Portugal, as well as foreign artists depicting Portuguese scenes. This study addresses questions concerning aspects of trombone technique that have not previously been considered and may have implications in the way the trombone was understood elsewhere in Europe. It focuses on aspects of technique depicted that may be representative of the trombone’s contemporary design and performance and therefore the manner in which the instrument was held and indeed played. Finally, this article suggests a transitional technical period when the way of holding the single-slide trumpet may have been used to play the trombone.Publisher PD

Teodoro Sampaio e Rui Barbosa no tabuleiro da política: estratégias e alianças de homens de cor (1880-1919)
No full textO artigo busca analisar, com base em episódios protagonizados por Teodoro Sampaio e Rui Barbosa, condições e forma de atuação política de homens de cor, entre 1880 e 1919. A trajetória de Sampaio nos permite perceber como um homem de cor, constituído num dos mais tradicionais redutos escravistas nas Américas, interpretou as relações e a gramática política que o forjaram como sujeito no pós-abolição. Teodoro Sampaio atravessou a década de 1880 buscando arregimentar recursos financeiros e políticos que garantissem a compra da alforria dos seus três irmãos e a consolidação da sua carreira de engenheiro. Já Rui Barbosa, branco, jurista, jornalista e político liberal, viveu o mesmo período empenhado na campanha emancipacionista e na luta abolicionista. Em 1919, Sampaio, já renomado, apoiou a campanha presidencial de Rui Barbosa. Naquela ocasião, o passado escravista e a cidadania da população negra justificaram as posições políticas de ambos. As fontes utilizadas são discursos, jornais, correspondência pessoal e inventários

Neuston C and N isotope ratios along the Malaspina 2010 Expedition
No full textRaw isotopic data of carbon and nitrogen ratios of neustonic samples collected during the Malaspina Expedition. Samples were collected along the Malaspina 2010 Expedition, which circumnavigated the globe and was carried out between December 2010 and July 2011 between 35° N and 40° S. Specifically, the neuston samples reported here included 10 oceanic Longhurst provinces (Longhurst, 2007). Four provinces in the Atlantic (Northeast Atlantic subtropical gyral – NASE; North Atlantic tropical gyral – NATR; Western tropical Atlantic – WTRA; South Atlantic gyral - SATL), 4 in the Pacific (South Pacific gyre – SPSG; Pacific equatorial divergence – PEQD; North Pacific tropical gyre – NPTG; North Pacific equatorial counter current – PNEC), and 2 in the Indian Ocean (Indian South subtropical gyre – ISSG; South subtropical convergence – SSTC). Samples were collected twice a day at 12 pm and 4 am, by towing a neuston sampler, with a mouth opening of 80 x 30 cm and a mesh size of 200 µm, at 2-3 knots for 10-15 minutes, which sampled the first 15 cm of the water at a distance of 5 m from the starboard of the vessel. The content of each sample was stored in 4% formaldehyde until analysis. The most abundant and representative taxa selected for SIA were copepods of the families Acartiidae, Calanidae, Corycaeidae, Oncaeidae, and Pontellidae, and Phylum Chaetognatha. Four functional groups (FG) were considered and taxa assigned as follow: FG1 = detritivores (Oncaeidae); FG2 = herbivores/omnivores (Acartiidae and Calanidae); FG3 = carnivores (Corycaeidae and Pontellidae) and FG4 = predators (Chaetognatha). All specimens selected for analysis were adults according to their morphological aspect under the microscope. Dried samples (~1 mg) were packed into tin capsules and measured in an elemental analyzer (Carlo Erba CHNSO 1108) coupled to an isotope-ratio mass spectrometer (Finnigan Matt Delta Plus)

Interview to Rui Furtado, AFA Consult foundator
No full textThis research addresses a series of projects built by the engineering company "AFA Consult" through the testimony of one of its engineers, Rui Furtado, who is also a professor of structures at the Universidade Lusófona do Porto, where the author was a student of his. The chosen projects follow the storyline of being built using a mixed structure of steel and concrete. The research presents, first, a series of case studies with mixed structural solutions for different architectural spaces. The article then focuses on the testimony of Rui Furtado through an interview that delves into the figure of Paulo Mendes da Rocha, following the thread of the Car Museum in Lisbon, one of the case studies with a mixed structure chosen. In addition, the professional relationship between Paulo and Rui is explored through the exhibition currently on view at Casa da Arquitectura (Porto), "Paulo, beyond drawing", of which Rui Furtado is the curator. Thus, the path is traced towards reconciling conclusions between the worlds of architecture and engineering, with humanism as the protagonist.La presente investigación aborda una serie de proyectos construidos por la empresa de ingeniería “AFA Consult” a través del testimonio de uno de sus ingenieros, Rui Furtado, que además es profesor de estructuras en la Universidade Lusófona do Porto, donde el autor fue alumno suyo. Los proyectos escogidos siguien la linea argumental de estar construidos mediante una estructura mixta de acero y hormigón. La investigación presenta, primeramente, una serie de casos de estudio con soluciones estructurales mixtas para diferentes espacios arquitectónicos. El artículo, posteriormente, se centra en el testimonio de Rui Furtado mediante una entrevista que profundiza en la figura de Paulo Mendes da Rocha, siguiendo el hilo del Museo de los Coches en Lisboa, uno de los casos de estudio con estructura mixta escogidos. Además, se explora la relación profesional entre Paulo y Rui mediante la exposición que actualmente puede verse en Casa da Arquitectura (Oporto), “Paulo, más allá del dibujo”, de la que Rui Furtado es comisario. Así, se traza el camino hacia unas conclusiones reconciliadoras entre los mundos de la arquitectura y la ingeniería, con el humanismo como protagonista.Peer Reviewe
