Comparative Study of Four Portuguese 16th Century Illuminated Manueline Charters based on Spectroscopy and Chemometrics Analysis

The comparative study based on spectroscopic analysis of the materials used to produce four sixteenth-century Manueline Charters (the Charters of Alcochete, Terena, Alandroal and Evora) was performed following a systematic analytical approach. SEM–EDS, l-Raman and l-FTIR analysis highlighted interesting features between them, namely the use of different pigments and colourants (such as different green and yellow pigments), the presence of pigments alterations and the use of a non-expected extemporaneous material (with the presence of titanium white in the Charter of Alcochete). Principal component analysis restricted to the C–H absorption region (3000–2840 cm-1) was applied to 36 infrared spectra of blue historical samples from the Charters of Alcochete,Terena, Alandroal and Évora, suggesting the use of a mixture of a triglyceride and polysaccharide as binder.

A new approach for computing a flood vulnerability index using cluster analysis

A Flood Vulnerability Index (FloodVI) was developed using Principal Component Analysis (PCA) and a new aggregation method based on Cluster Analysis (CA). PCA simplifies a large number of variables into a few uncorrelated factors representing the social, economic, physical and environmental dimensions of vulnerability. CA groups areas that have the same characteristics in terms of vulnerability into vulnerability classes. The grouping of the areas determines their classification contrary to other aggregation methods in which the areas' classification determines their grouping. While other aggregation methods distribute the areas into classes, in an artificial manner, by imposing a certain probability for an area to belong to a certain class, as determined by the assumption that the aggregation measure used is normally distributed, CA does not constrain the distribution of the areas by the classes. FloodVI was designed at the neighbourhood level and was applied to the Portuguese municipality of Vila Nova de Gaia where several flood events have taken place in the recent past. The FloodVI sensitivity was assessed using three different aggregation methods: the sum of component scores, the first component score and the weighted sum of component scores. The results highlight the sensitivity of the FloodVI to different aggregation methods. Both sum of component scores and weighted sum of component scores have shown similar results. The first component score aggregation method classifies almost all areas as having medium vulnerability and finally the results obtained using the CA show a distinct differentiation of the vulnerability where hot spots can be clearly identified. The information provided by records of previous flood events corroborate the results obtained with CA, because the inundated areas with greater damages are those that are identified as high and very high vulnerability areas by CA. This supports the fact that CA provides a reliable FloodVI.

Relatório no âmbito da unidade curricular prática de ensino supervisionada, realizada na Escola Secundária/3 Rainha Santa Isabel de Estremoz

O presente relatório foi produzido no âmbito da unidade curricular Prática de Ensino Supervisionada, que faz parte do Mestrado em Ensino do Português no 3º Ciclo do Ensino Básico e Ensino Secundário e de Espanhol nos Ensinos Básico e Secundário, sob a orientação da Professora Doutora Ângela Maria Franco Martins Coelho de Paiva Balça. Identifica-se, na sua essência basilar, como um trabalho reflexivo-descritivo sobre a prática aplicada e efetuada no ano letivo 2015/2016, no lecionamento das disciplinas de Português em duas turmas de 10º ano, e de Espanhol – Língua Estrangeira I numa de 7º ano, na Escola Secundária/3 Rainha Santa Isabel, de Estremoz. Além do mais, também constitui o expoente de todo o processo levado a cabo durante os dois anos do Mestrado, o qual permitiu e conduziu à revisão, modificação, inovação e progressão em matéria de conceitos, ideias, noções, ações e teorias, quer fossem mais antigas ou recentes. Este é o produto final e contributo para o desenvolvimento e melhoria a nível pessoal e profissional. Através do conhecimento da literatura teórica e da sua aplicação na ação, a reflexão compromete-nos a cumprir uma prática fundamentada e apoiada em toda a documentação mundial, europeia e portuguesa normativa e de referência para o exercício da profissão docente o mais completo e eficaz possível. Mais do que um relatório, é uma avaliação orientativa da dimensão transformadora no desempenho docente que, na sua parte mais cogitativa, expõe estruturalmente: a observação e o seu registo; a observação em contexto; a planificação; a orientação; a componente letiva – aulas lecionadas (análise, aprendizagem e melhorias) e a pesquisa reflexiva na abordagem dos inquéritos passados nas turmas de Português e de Espanhol; e, por fim, a abordagem reflexiva sobre a avaliação formativa das aprendizagens realizada às turmas de 10º ano, na disciplina de Português; ABSTRACT: This report was produced in the scope of Supervised Teaching Practice’s curricular unit, which is part of the Master’s Degree in Teaching Portuguese for the 3rd stage of Primary Education and Secondary Education, and Spanish Foreign Language Teaching for Primary and Secondary Education, under the supervision of Dr. Ângela Maria Franco Martins Coelho de Paiva Balça. In its basic essence, this is a reflective and descriptive paper about practices applied and performed for the 2015-2016 school year to teach Portuguese, in two tenth grade classes, and Spanish as a Foreign Language, in one seventh grade class at Rainha Santa Isabel School of Estremoz. Furthermore, it outlines the entire process carried out during the two years of the Master’s Degree, which provided and led to review, change, breakthrough, and advancement regarding concepts, ideas, assumptions, and theories, whether they were pre-existing or more recent. This is the final product and the contribution towards development and improvement in personal and professional terms. Through knowledge of theoretical literature and applying it to practice, the reflection leads us to compile substantiated and supported practice in all worldwide, European, and Portuguese standards and reference documentation for the most effective pursuit of the profession. More than a report, this is an evaluation of transformation in teaching performance that structurally examines the following: observation and its registration; observation in the field; lesson design; guidance and monitoring; a teaching component (analysis, apprenticeships, and improvements) with a reflective element based on the results of the Portuguese and Spanish class surveys; and, finally, a reflexive approach about formative assessment of student learning that took place within the Portuguese course.

Analysis of Pancreas Histological Images for Glucose Intolerance Identification using Wavelet Decomposition

Subtle structural differencescan be observed in the islets of Langer-hans region of microscopic image of pancreas cell of the rats having normal glucose tolerance and the rats having pre-diabetic(glucose intolerant)situa-tions. This paper proposes a way to automatically segment the islets of Langer-hans region fromthe histological image of rat's pancreas cell and on the basis of some morphological feature extracted from the segmented region the images are classified as normal and pre-diabetic.The experiment is done on a set of 134 images of which 56 are of normal type and the rests 78 are of pre-diabetictype. The work has two stages: primarily,segmentationof theregion of interest (roi)i.e. islets of Langerhansfrom the pancreatic cell and secondly, the extrac-tion of the morphological featuresfrom the region of interest for classification. Wavelet analysis and connected component analysis method have been used for automatic segmentationof the images. A few classifiers like OneRule, Naïve Bayes, MLP, J48 Tree, SVM etc.are used for evaluation among which MLP performed the best.
