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

Analysis of plasma-mediated ablation in aqueous tissue
No full textPlasma-mediated ablation using ultrafast lasers in transparent media such as aqueous tissues is studied. It is postulated that a critical seed free electron density exists due to the multiphoton ionization in order to trigger the avalanche ionization which causes ablation and during the avalanche ionization process the contribution of laser-induced photon ionization is negligible. Based on this assumption, the ablation process can be treated as two separate processes - the multiphoton and avalanche ionizations - at different time stages; so that an analytical solution to the evolution of plasma formation is obtained for the first time. The analysis is applied to plasma-mediated ablation in corneal epithelium and validated via comparison with experimental data available in the literature. The critical seed free-electron density and the time to initiate the avalanche ionization for sub-picosecond laser pulses are analyzed. It is found that the critical seed free-electron density decreases as the pulse width increases, obeying a tp-5.65 rule. This model is further extended to the estimation of crater size in the ablation of tissue-mimic polydimethylsiloxane (PDMS). The results match well with the available experimental measurements.Peer reviewed
Literary Strategies in Rui Rocha
No full textInteressa a este artigo perquirir as estratégias, de hibridismo, alegoria e voz poética, usadas pelo autor, Rui Rocha, para compor alguns dos poemas de suas obras Taotologias e A oriente do silêncio, apontando o modo como as cenas imagéticas apresentam-se como arte final.
ABSTRACT
This article investigates the hybridism strategies, allegory strategies and poetic voice strategies, who Rui Rocha author uses to compose some of his poems. He wrote Taotologias and A oriente do silêncio. And also, this article wants to demonstrate the way in which scenes helps to make the final art of those books.

Multi-objective Optimal Energy Management Strategy and Economic Analysis for an Range-Extended Electric Bus
No full textAbstractAn optimal energy management strategy is proposed to match engine fuel consumption and battery SOH of REEB. Models of APU fuel consumption and battery SOH loss are established and multi-objective performance function is provided. DP algorithm is adopted to solve the optimization problem. Under the conditions of different drive cycles, different SOH penalty coefficients are analyzed to reveal its effects. Considering the total life-cycle costs, simulations prove that when battery is not to be replaced, and the capacity configuration and SOH penalty coefficient of battery are both taken the minimum, the best economical results can be achieved
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
