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.

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.

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.
On the rate of convergence of uniform approximations for sequences of distribution functions
João Lita da Silva,Luís Pedro Ramos 한국통계학회 2014 Journal of the Korean Statistical Society Vol.43 No.1
In this paper, we develop uniform bounds for the sequence of distribution functions ofg(Vn + μn), where g is some smooth function, {Vn, n ≥ 1} is a sequence of identicallydistributed random variables with common distribution having a bounded derivative and{μn} are constants such that μn → ∞. These bounds allow us to identify a suitablesequence of random variables which is asymptotically of the same type of g(Vn + μn)showing that the rate of convergence for these uniform approximations depends on theratio of the second derivative to the first derivative of g. The corresponding generalizationto the multivariate case is also analyzed. An application of our results to the STATIS-ACTmethod is provided in the final section.

We analyzed modified spouted bed configurations incorporating three different types of mechanical stirrer, in comparison to a conventional spouted bed. Straight-blade, inclined-blade, and helical screw agitators were used with different types of inert particles. The behavior of the fluid dynamic curves was qualitatively similar for the systems with agitators and the conventional design, except for the screw-type agitator. For the straight-blade and inclinedblade agitators, increase of the rotation speed had a positive effect on the fluid dynamic parameters, reducing the air flow and the pressure drop in the bed. The effects of rotation speed and blade inclination on the fluid dynamics were minimized at 240 rpm, although the mass of particles could influence these parameters. The inclined-blade stirrer performed the best, reducing airflow between 40 and 66% compared to the conventional spouted bed. For the screw-type stirrer, the reduction was around 27% in some of the experiments. The rotation speed of the stirrer and the air flow to agitate the bed affect the average cycle time of the process, with a stronger effect on the rotation speed. Overall, the use of the stirrers in the bed provided significant improvement, with reduction of both the air flow, the pressure drop and average cycle time, as well as greater stability of the bed.
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.
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.
Cottonseed biodiesel oxidative stability in mixture with natural antioxidants
João Paulo Almeida Freitas,Fernanda Rocha Morais França,Maria Susana Silva,Richard James Toms,Gabriel Francisco da Silva 한국화학공학회 2019 Korean Journal of Chemical Engineering Vol.36 No.8
We evaluated the antioxidant power of the natural extracts catechin, curcumin and quercetin on the oxidative stability of methylic cottonseed oil biodiesel by applying the simplex-centroid augmented mixture experimental design, in addition to verifying the existence and the type of synergy among the extracts. The oxidative stability was measured using Rancimat method (EN 14112) for biodiesel added with 1,000, 2,000 and 3,000 ppm of additives, and compared with the commercial synthetic antioxidant butyl hydroxyanisole at the same concentrations. All additives had a positive effect on biodiesel oxidative stability; in addition, catechin and quercetin proved to be more efficient than the synthetic antioxidant, whereas curcumin showed similar results. The results also revealed that the interactions among the extracts varied not only with the proportion in which they were added to the biodiesel, but also with the total concentration, so that the increase in concentration reduced the magnitude of the synergistic effect.
Revolutionising textile manufacturing: a comprehensive review on 3D and 4D printing technologies
João P. Manaia,Fábio Cerejo,João Duarte 한국의류학회 2023 Fashion and Textiles Vol.10 No.1
An exhaustive and integrative overview of recent developments in 3D and 4D textiles based on Additive Manufacturing (AM) were provided in order to identify the current state‐of‐the‐art. Despite all scientific progress, AM applied on textiles is a challenging technique and is still at an embryonic stage of research and technological development (R&TD), mainly due to the technological gap between featured prototypes and scalability in manufacturing. Despite its full potential across a range of different applications, such as development of functional filament fibres/wires, 3D printing on textiles, 3D printing completed garments and 4D textiles, needs future developments. Although, AM applied on textiles, enables cost and resource efficiency for small scale production through localised production, shorten supply chain and demand driven manufacture, both customisable and scalable, embracing cost and environmental sustainability. The opportunities and limits of 3D and 4D printing textiles are also discussed. Finally, the conclusion highlights the potential future development and application of the convergence of advanced computational design techniques, product customization, mathematical modelling, simulation, and digital modelling within multifunctional textiles.
