Príncipes encobertos e princesas enamoradas: do disfarce por amor no teatro de Gil Vicente

Maria João Pais do Amaral 한국 포르투갈-브라질 학회 2008 포르투갈-브라질 연구 Vol.5 No.1

The main object of this essay is love disguise in two plays of Gil Vicente, Portuguese dramatist who developed his theatrical activity between 1502 and 1536 under the patronage of the monarchs Manuel I and João III. Widely spread in 16th century European literature, the motif of love disguise has its origins in chivalry romances, which are one of the many diverse sources of Gil Vicente's court theatre and also one of the dramatist's first spectators' favourite kind of books. I analyse it in Comédia do Viúvo and Tragicomédia de D. Duardos, where the protagonists, princes Rosvel and Duardos, hide their true identity and social rank from their beloved in order to prove the authenticity of their affection. In a first moment, I compare the way each of these two princes uses love disguise, reflecting on the function and meaning of the obvious differences this comparative analysis brings into light. In a second moment, I relate those differences with both the dramatic genre each of these two plays belongs and the conception of love that is on the basis of the stories enacted in Viúvo and Duardos, which, although originating in courtly love conventions, goes far beyond it. Finally, and because Gil Vicente's theatre is an art that strongly depends on circumstances, the date on which these spectacles were presented for the first time before the Portuguese king and court, as well as the purposes they were meant to fulfil, are also taken into consideration in this reflection on the innovative use of love disguise motif by one of the most important Portuguese dramatists of all times.

Adriana Hamond Regua-Mangia,Alice Gonçalves M. Gonzalez,Aloysio M. F. Cerqueira,João Ramos C.Andrade 대한수의학회 2012 Journal of Veterinary Science Vol.13 No.2

Escherichia (E.) coli serotype O157:H7 is a globally distributed human enteropathogen and is comprised of microorganisms with closely related genotypes. The main reservoir for this group is bovine bowels, and infection mainly occurs after ingestion of contaminated water and food. Virulence genetic markers of 28 O157:H7 strains were investigated and multilocus enzyme electrophoresis (MLEE) was used to evaluate the clonal structure. O157:H7 strains from several countries were isolated from food, human and bovine feces. According to MLEE, O157:H7 strains clustered into two main clonal groups designated A and B. Subcluster A1 included 82% of the O157:H7 strains exhibiting identical MLEE pattern. Most enterohemorrhagic E. coli (EHEC) O157:H7 strains from Brazil and Argentina were in the same MLEE subgroup. Bovine and food strains carried virulence genes associated with EHEC pathogenicity in humans.

Sporotrichosis is a chronic and subacute mycosis causing epidemiological outbreaks involving sick cats and humans in southeastern Brazil. The systemic disease prevails in cats and in humans, with the symptoms restricted to the skin of immunocompetent individuals. Under these conditions, the prolonged treatment of animals and cases of recurrence justify the discovery of new treatments for sporotrichosis. This work addresses the antifungal activity of silver salts of Keggin-type heteropolyacid salts (Ag-HPA salts) such as Ag3[PW12O40], Ag6[SiW10V2O40], Ag4[SiW12O40] and Ag3[PMo12O40] and interactions with the antifungal drugs itraconazole (ITC), terbinafine (TBF) and amphotericin B (AMB) on the yeast and mycelia forms of Sporothrix spp. Sporothrix spp. yeast cells were susceptible to Ag-HPA salts at minimum inhibitory concentration (MIC) values ranging from 8 to 128 μg/ml. Interactions between Ag3[PW12O40] and Ag3[PMo12O40] with itraconazole and amphotericin B resulted in higher antifungal activity with a reduction in growth and melanization. Treated cells showed changes in cell membrane integrity, vacuolization, cytoplasm disorder, and membrane detachment. Promising antifungal activity for treating sporotrichosis was observed for the Ag-HPA salts Ag3[PMo12O40] and Ag3[PW12O40], which have a low cost, high yield and activity at low concentrations. However, further evaluation of in vivo tests is still required.

Monetary Aggregates and Macroeconomic Performance: The Portuguese Escudo, 1911–1999

João Tovar Jalles 한국국제경제학회 2019 International Economic Journal Vol.33 No.4

This paper provided a full characterization of several monetary aggregates over Portuguese’s historical economic business cycles. By focusing on the 1911–1999 period, the paper also revisits the issue of the role of money on real macroeconomic outcomes, inspired from the monetarists versus Keynesians debate on quest for validity of money (non-)neutrality. By means of descriptive statistics we first uncover that money changes were associated with changes in real economic activity. Most monetary aggregates are more volatile than GDP, display high serial autocorrelation, are generally countercyclical and lead the economic cycle. Then, through econometric analysis, our results show that our monetary series were characterized by unit roots and were cointegrated with real GDP. Evidence also suggested that money supply Granger-caused real GDP. Finally, both variance decomposition and impulse response function analyses from an estimated BVAR, uncovered a persistent and mutual effect running from a shock in real GDP to monetary aggregates and vice versa, therefore supporting the money non-neutrality hypothesis in the case of Portugal.

Numerical analysis of spalling of concrete cover at high temperature

Joško Ožbolt,Goran Periškic,Hans-Wolf Reinhardt,Rolf Eligehausen 사단법인 한국계산역학회 2008 Computers and Concrete, An International Journal Vol.5 No.4

In the present paper a 3D thermo-hygro-mechanical model for concrete is used to study explosive spalling of concrete cover at high temperature. For a given boundary conditions the distribution of moisture, pore pressure, temperature, stresses and strains are calculated by employing a threedimensional transient finite element analysis. The used thermo-hygro-mechanical model accounts for the interaction between hygral and thermal properties of concrete. Moreover, these properties are coupled with the mechanical properties of concrete, i.e., it is assumed that the mechanical properties (damage) have an effect on distribution of moisture (pore pressure) and temperature. Stresses in concrete are calculated by employing temperature dependent microplane model. To study explosive spalling of concrete cover, a 3D finite element analysis of a concrete slab, which was locally exposed to high temperature, is performed. It is shown that relatively high pore pressure in concrete can cause explosive spalling. The numerical results indicate that the governing parameter that controls spalling is permeability of concrete. It is also shown that possible buckling of a concrete layer in the spalling zone increases the risk for explosive spalling.

The Ciliary Transition Zone: Finding the Pieces and Assembling the Gate

João Gonçalves,Laurence Pelletier 한국분자세포생물학회 2017 Molecules and cells Vol.40 No.4

Eukaryotic cilia are organelles that project from the surface of cells to fulfill motility and sensory functions. In vertebrates, the functions of both motile and immotile cilia are critical for em-bryonic development and adult tissue homeostasis. Importantly, a multitude of human diseases is caused by abnormal cilia biogenesis and functions which rely on the com-partmentalization of the cilium and the maintenance of its protein composition. The transition zone (TZ) is a specialized ciliary domain present at the base of the cilium and is part of a gate that controls protein entry and exit from this organelle. The relevance of the TZ is highlighted by the fact that several of its components are coded by ciliopathy genes. Here we review recent developments in the study of TZ proteomes, the mapping of individual compo-nents to the TZ structure and the establishment of the TZ as a lipid gate.

UbiGDSS : A Theoretical Model to Predict Decision-Makers’ Sat-isfaction

João Carneiro,Ricardo Santos,Goreti Marreiros,Paulo Novais 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.7

The market globalization and the firms’ internationalization hinder the matching of the top managers’ agenda, making it difficult to meet in the same space or time. On the one hand, the appearance of Ubiquitous Group Decision Support Systems (UbiGDSS) ena-bled individuals to gather and make decisions in different spaces at different times, but on the other hand, originated problems related to the lack of human interaction. To under-stand how the arguments used can influence each of the decision-makers, what is their satisfaction regarding the decision made, and other affective issues such as emotions and mood, are some examples of that lack. In order to try to overcome this lack, we propose a theoretical model that is specially designed for agents, helping to understand the interac-tions impact on each agent and their satisfaction with the decision made.

João P. M. Pragana,Valentino A. M. Cristino,Ivo M. F. Bragança,Carlos M. A. Silva,Paulo A. F. Martins 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.7 No.3

This paper is focused on the integration of metal forming operations in hybrid systems that combine additive manufacturing (AM) by gas metal wire arc and subtractive manufacturing by machining. The investigation is carried out in AISI 316L stainless steel wire and draws from tensile testing to incremental sheet forming of truncated conical shapes. Commercial sheets from the same material are utilized for comparison purposes. Thickness measurements, digital image correlation (DIC), circle grid analysis (CGA) and microstructural and scanning electron microscopy (SEM) observations are carried out to understand how diff erent is the mechanical behaviour of the deposited metal from that of commercial metal sheets and how signifi cant is the infl uence of the deposited metal microstructure on its overall formability. Results confi rm that integration of metal forming operations in hybrid AM routes is feasible despite the formability of deposited metal being smaller than that of the commercial metal sheets due to the strong anisotropy induced by the dendritic based microstructure of the deposited metal. Incremental forming of two deposited parts also allows concluding that integration of metal forming operations in hybrid AM systems is a step towards green and sustainable manufacturing by extending their fi eld of applicability to the fabrication of complex ready-to-use parts requiring combination of diff erent processes.

The Transfiguration of Violence: On the Meta‐Ontological Dimension of the Way of Peace

Joào J. Vila-Chà 서강대학교 생명문화연구소 2011 생명연구 Vol.22 No.-

This paper considers violence as a multifaceted problem, whereby at its core is not only a political but also an ontological dimension. After all, even when considered as a political act, violence represents a direct participation in the mystery of evil. The phenomenon of violence always refers to both an attitude in the agent that perpetrates it as well as to the evil consequences that such attitude produces on the part of whoever suffers it. Hence the importance of distinguishing between violence and power, a distinction that as such presupposes that the presence of violence means that true and authentic power is missing. In order to explain the nature of violence, hence, we defend that power presupposes plurality and, as such, can be established only through non‐violent means. At the center of the analysis is the notion of discourse and the demonstration (with Levinas) of the ethical nature of any authentic act of human language.
