The Cloister of Santa Clara-a-nova monastery, analysis of architectural typology used at the time of the portuguese restauration

This article intends to focus on the first phase of construction of the cloister of Mosteiro de Santa Clara-a-Nova in Coimbra (Portugal), characterized by the architectural and military tratadistics of the Restoration period. From the documentary research and the projectual representation, it is proposed to contextualize its original typology. The cloister of Mosteiro de Santa Clara-a-Nova, although it is a major work of the Restoration and the Cycle of Aqueduto das Águas Livres of Lisboa, is poorly studied. At a time when the work of the kingdom was conditioned by the expenses of the war, those of greater relevance were of military character and erected in the geographical areas of territorial defence. It is perhaps necessary to prove the legitimacy of Portuguese independence, which led to the reinforcement of the use of mental processes and scholastic theses, which will cultivate the propagandist of Culto Isabelino in Casa de Bragança. [1] The progressive silting of the old convent, together with the political need, meant that in 1649 D. João IV ordered that the first stone be laid for the construction of the new Monastery of Santa Clara de Coimbra, in which he determines that in Latin it refers to the Queen Santa Isabel as his Grandmother and Lady. The documents related to the construction of Mosteiro de Santa Clara-a-Nova show that the original plants and infrastructures are responsibility of Friar Turriano. [2] Regardless the regime of observance, following the long tradition of inheriting public offices, Friar Torriano receives from D. João IV the position of Chief Engineer (Engenheiro-mor) of the Kingdom. For thirteen years he traces several religious houses and even succeedes Mateus do Couto (uncle) in the work of Forte de São Lourenço da Cabeça Seca, in Barra do Tejo. [3] The architectural knowledge of Friar Turriano can be verified in the study of his library’s catalog, which he inherits of his father Leonardo Turriano (Engineer-mor of Portugal), and where stand out several architectural treatises, such as those of Sebastiano Serlio, which he studied and wrote down in detail. In fact there is a correlation between these and the solution adopted in the first compositional scheme of the cloister. [4] The first reference to the cloister (1700) appears in the register of the letters of Superintendent Marquês do Alegrete, where he describes how he conferred with Manuel do Couto, the copies of Friar Turriano’s plans, and decided to start the work of the cistern. Manuel do Couto succeeded his protector, Mateus do Couto (Nephew), with whom he learned the office of architect under the patronage of the Marquis. In fact this military architectural culture, whose origin leads to Mateus do Couto (Uncle), will fit the project outlined by Frei Torriano, whose appearance despite Serliana, is structurally military. In 1731 Custodio Vieira measures the works that had been executed in all the gallery of the first floor of the cloister. The measurement suggests that at least two galleries were already erected; despite the advance, in 1737 is demanded the demolition of the dome, as it was threatening ruin on the side of the olive grove. On its direction the structural reform begins, definitively altering the original typology. Custódio Viera and his successor, Carlos Mardel, besides changing the structure, introduce a Baroque model based on the politics of happiness of the peoples, linked to the currents of the Enlightenment.CONCLUSIONS The cloister we can visit nowadays, in Mosteiro de Santa Clara-a-Nova is a hybrid, whose skeleton is inspired by the reading of Serlio's works. This work by Frei Turriano still presents features of military architecture, which are translated not only in the decorative bareness of the façade but also in the large dimensions of the galleries of its arches and domes. It could have been the proportions of these structural elements that gave rise to the fall of the domes, changing forever its original typology. Regardless of whether any of the plants mentioned in this article have never been found, it is possible through the documentation studied to present a 3d model of the typology that Torriano would have planned

Estudo comparativo da resistência adesiva de resinas compostas na cimentação de restaurações indiretas

Dissertação para obtenção do grau de Mestre no Instituto Superior de Ciências da Saúde Egas MonizObjetivos: Avaliar a resistência adesiva (μTBS) de diferentes materiais na cimentação de restaurações indiretas, confecionadas em materiais distintos. Classificar a falha em relação ao tipo de fratura. Avaliar morfologicamente com Microscópio Eletrónico de Varrimento (MEV) as interfaces adesivas obtidas. Materiais e métodos: Dezoito molares hígidos foram submetidos ao selamento imediato da dentina (IDS) após exposição da dentina média. Após 24 horas, foram divididos aleatoriamente por dois grupos consoante o tipo de material restaurador, resina composta (Filtek™ Z100 3M ESPE) ou cerâmica (IPS e.max CAD - Ivoclar Vivadent). Cada grupo foi subdividido em três subgrupos em função do material de adesão. Através de um cilindro calibrado foram obtidos 9 discos em resina composta (Filtek™ Z100 3M ESPE) com 4x4 mm e aderidos às coroas com Filtek™ Z100 (3M ESPE), Filtek™ Bulk Fill (3M ESPE) e RelyX™ Veneer (3M ESPE). Foram também produzidos 9 blocos em cerâmica (IPS e.max CAD - Ivoclar Vivadent) com dimensões semelhantes e aderidos com os mesmos materiais. As amostras foram armazenadas durante 24 horas, a 37ºC, e posteriormente seccionadas em palitos com uma lâmina diamantada a baixa rotação, na direção X e Y. Os palitos foram tracionados numa máquina de testes universal à velocidade de 1 mm/min. As fraturas resultantes foram classificadas com o auxílio de uma lupa estereoscópica. As interfaces adesivas foram avaliadas morfologicamente com MEV. Na análise estatística foram aplicados os testes t de Student, Anova One-Way (p≤0,05). Resultados: As diferenças entre os materiais utilizados na adesão das restaurações indiretas não são estatisticamente significativas. Os valores mais elevados de adesão foram obtidos pelo cimento de resina RelyX™ Veneer. Conclusão: A resistência adesiva (μTBS) da cimentação de restaurações indiretas não é influenciada pelo material utilizado na adesão

Análise do desempenho de regras da análise técnica aplicada ao mercado intradiário do contrato futuro do índice Ibovespa

Este artigo tem como objetivo verificar a robustez do contéudo preditivo de regras da análise técnica, usando informações intradiárias do mercado futuro do índice de ações da Bolsa de Valores de São Paulo (Ibovespa Futuro). A metodologia sugerida foi a avaliacão em grupos, conforme os resultados de Baptista (2002), tal que as regras são obtidas conforme os resultados em alguns dos subperíodos estudados, sendo testadas em períodos subsequentes. Como resultado, obteve-se robustez ao longo do tempo e à taxa de amostragem dos dados no desempenho das regras acima do benchmark (buy-and-hold), porém considerações realistas acerca do momento de compra, assim como da corretagem (exceto grande investidor), podem reduzir substancialmente os ganhos

Alinhamento de vocabulário de domínio utilizando os sistemas AML e LogMap

Introduction: In the context of the Semantic Web, interoperability among heterogeneous ontologies is a challenge due to several factors, among which semantic ambiguity and redundancy stand out. To overcome these challenges, systems and algorithms are adopted to align different ontologies. In this study, it is understood that controlled vocabularies are a particular form of ontology. Objective: to obtain a vocabulary resulting from the alignment and fusion of the Vocabularies Scientific Domains and Scientific Areas of the Foundation for Science and Technology, - FCT, European Science Vocabulary - EuroSciVoc and United Nations Educational, Scientific and Cultural Organization - UNESCO nomenclature for fields of Science and Technology, in the Computing Sciences domain, to be used in the IViSSEM project. Methodology: literature review on systems/algorithms for ontology alignment, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses - PRISMA methodology; alignment of the three vocabularies; and validation of the resulting vocabulary by means of a Delphi study. Results: we proceeded to analyze the 25 ontology alignment systems and variants that participated in at least one track of the Ontology Alignment Evaluation Initiative competition between 2018 and 2019. From these systems, Agreement Maker Light and Log Map were selected to perform the alignment of the three vocabularies, making a cut to the area of Computer Science. Conclusion: The vocabulary was obtained from Agreement Maker Light for having presented a better performance. At the end, a vocabulary with 98 terms was obtained in the Computer Science domain to be adopted by the IViSSEM project. The alignment resulted from the vocabularies used by FCT (Portugal), with the one adopted by the European Union (EuroSciVoc) and another one from the domain of Science & Technology (UNESCO). This result is beneficial to other universities and projects, as well as to FCT itself.Introdução: No contexto da Web Semântica, a interoperabilidade entre ontologias heterogêneas é um desafio devido a diversos fatores entre os quais se destacam a ambiguidade e a redundância semântica.

Designing lesson studies to support teachers’ professional development

In this paper we address design issues of lesson studies that aim to support practicing teachers’ professional development. We discuss these issues based in the cases of two lesson studies that we conducted in the academic year of 2013-2014 in a cluster of schools in Lisbon. We strive to show that, besides the consideration of the mathematical content, task features, and focus on student reasoning, attention needs to be paid to organizational issues regarding the way the teachers are invited to become involved in lesson studies and to the collaborative environment provided. We also conclude critical design factors for the success of a lesson study include the investigation style of the whole activity, the combination of teachers’ experiential knowledge with research knowledge, and the exploratory and collaborative environment that frames the activities that the teachers undertake.info:eu-repo/semantics/publishedVersio

Development, psychopathology and attachment: an exploratory study with institutionalized children and their caregivers

O presente estudo exploratório examinou o desenvolvimento mental e a qualidade do funcionamento sócio-emocional de 16 crianças entre os 3 e os 6 anos, institucionalizadas em Centros de Acolhimento Temporário, relacionando-os com a qualidade das narrativas sobre o apego das suas cuidadoras. Foram utilizadas a Escala de Desenvolvimento Mental de Griffiths, o Questionário de Comportamentos, as Narrativas sobre o Apego e o Attachment Q-Sort. Os resultados revelaram que o nível de desenvolvimento das crianças foi inferior aos valores normativos. Além disso, os valores apresentados ao nível da psicopatologia, em termos de sintomas de internalização e de externalização, aproximaram-se dos valores clínicos. Não obstante e, em contraste com o esperado, a maioria das crianças apresentou valores próximos da segurança (base segura), os quais não estão associados com a qualidade das narrativas sobre o apego das suas cuidadoras. Os resultados são discutidos com base no impacto da privação em meio institucional para o desenvolvimento na infância.This exploratory study examined mental development and the quality of socio-emotional functioning of 16 institutionalized children, aged from 3 to 6 years old, relating them with the quality of their caregivers’ attachment narratives. Griffiths Developmental Scales, Child Behavior Checklist, Attachment Script Representation and Attachment Q-Sort were used in the psychological assessment. Results showed that chidren’s developmental level was placed below normative data. Furthermore, data regarding externalizing and internalizing psychopathology symptoms were close to the clinical population. Nevertheless, and in contrast to our hypothesis, most children presented almost mormative attachments scores (secure base), but this was not related to the quality of attachement narratives presented by their caregivers. The implications of these findings are discussed in light of the impact of institutional deprivation in child development.Fundação para a Ciência e a Tecnologia (FCT). PTDC/PSI-PCL/101506/200

Análise do Desempenho de Regras de Análise Técnica Aplicada ao Mercado Intradiário do Contrato Futuro do Índice Bovespa

The purpose of this article is to investigate whether, how and when, from a statistical standpoint, Technical Analysis strategies tools hold true for the futures contract of Ibovespa Index, negotiated at the Brazilian Futures Exchange (“Bolsa Brasileira de Mercadorias e Futuros – BM&F”), using tick-by-tick data. The methodology applied was suggested by Baptista (2002), in a way that the rules are grouped according to similar performance and are validated in subsequent intervals of time. As a result, in all periods and independently of sampling frequency, the strategies over-perform the buy-and-hold startegy, but realistic considerations about transaction costs and timing can reduce the gain

Effect of photostimulation through red LED light radiation on natural fermentation of table olives: An innovative case study with Negrinha the Freixo variety

In this study, for the first time, red LED light radiation was applied to the fermentation process of table olives using the Negrinha de Freixo variety. Photostimulation using LED light emission (630 ± 10 nm) is proposed to shorten and speed up this stage and reduce time to market. Several physical-chemical characteristics and microorganisms (total microbial count of mesophilic aerobic, molds, yeasts, and lactic acid bacteria) and their sequence during fermentation were monitored. The fermentation occurred for 122 days, with two irradiation periods for red LED light. The nutritional composition and sensory analysis were performed at the end of the process. Fermentation under red LED light increased the viable yeast and lactic acid bacteria (LAB) cell counts and decreased the total phenolics in olives. Even though significant differences were observed in some color parameters, the hue values were of the same order of magnitude and similar for both samples. Furthermore, the red LED light did not play a relevant change in the texture profile, preventing the softening of the fruit pulp. Similarly, LED light did not modify the existing type of microflora but increased species abundance, resulting in desirable properties and activities. The species identified were yeasts - Candida boidinii, Pichia membranifaciens, and Saccharomyces cerevisiae, and bacteria - Lactobacillus plantarum and Leuconostoc mesenteroides, being the fermentative process dominated by S. cerevisiae and L. plantarum. At the end of fermentation (122 days), the irradiated olives showed less bitterness and acidity, higher hardness, and lower negative sensory attributes than non-irradiated. Thus, the results of this study indicate that red LED light application can be an innovative technology for table olives production.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support through national funds FCT/MCTES (PIDDAC) to CIMO (UIDB/00690/2020 and UIDP/00690/2020) and SusTEC (LA/P/0007/2021).
