Analysis of sandwich beam structures using kriging based higher order models

Functionally graded composite materials can provide continuously varying properties, which distribution can vary according to a specific location within the composite. More frequently, functionally graded materials consider a through thickness variation law, which can be more or less smoother, possessing however an important characteristic which is the continuous properties variation profiles, which eliminate the abrupt stresses discontinuities found on laminated composites. This study aims to analyze the transient dynamic behavior of sandwich structures, having a metallic core and functionally graded outer layers. To this purpose, the properties of the particulate composite metal-ceramic outer layers, are estimated using Mod-Tanaka scheme and the dynamic analyses considers first order and higher order shear deformation theories implemented though kriging finite element method. The transient dynamic response of these structures is carried out through Bossak-Newmark method. The illustrative cases presented in this work, consider the influence of the shape functions interpolation domain, the properties through-thickness distribution, the influence of considering different materials, aspect ratios and boundary conditions.

Octopus Lipid and Vitamin E Composition: Interspecies, Interorigin, and Nutritional Variability

Octopus vulgaris, Octopus maya, and Eledone cirrhosa from distinct marine environments [Northeast Atlantic (NEA), Northwest Atlantic (NWA), Eastern Central Atlantic, Western Central Atlantic (WCA), Pacific Ocean, and Mediterranean Sea] were characterized regarding their lipid and vitamin E composition. These species are those commercially more relevant worldwide. Significant interspecies and interorigin differences were observed. Unsaturated fatty acids account for more than 65% of total fatty acids, mostly ω-3 PUFA due to docosahexaenoic (18.4−29.3%) and eicosapentanoic acid (11.4− 23.9%) contributions. The highest ω-3 PUFA amounts and ω-3/ω-6 ratios were quantified in the heaviest specimens, O. vulgaris from NWA, with high market price, and simultaneously in the lowest graded samples, E. cirrhosa from NEA, of reduced dimensions. Although having the highest cholesterol contents, E. cirrhosa from NEA and O. maya from WCA have also higher protective fatty acid indexes. Chemometric discrimination allowed clustering the selected species and several origins based on lipid and vitamin E profiles.

HEART ANEURYSM IN CHAGAS' DISEASE

This prospective study on 41 autopsy collected human hearts concerns the "apical" lesion in Chagas' disease. Previous report did not show a correlation between lesion frequency and heart weight then discarding a vascular factor in its pathogenesis. The present paper involves other variables besides the heart weight to evaluate the relative coronary insufficiency. Distinct colored gel (green and red) injected through the capillary beds of both coronary arteries defined the extent of both vessels before separating the atria and removing the sub-epicardium fat. The Right Ventricle (RV) and Left Ventricle (LV) free walls furnished the RV/LV mass ratio. The myocardium mass colored green (right coronary artery - RC) and the whole Ventricular Weight (VW) determined the RC/VW mass ratio. The heart weight plus these mass ratios, graded and added, composed a score inversely proportional to the myocardium irrigation condition. It intended to be a more sensitive morphologic evaluation of the relative ischaemia to correlate to the apical lesion. This study showed a right deviation for the relative accumulated frequency of lesions plotted as a score function and a significant difference for higher scores in hearts with aneurysm. It suggests a ischaemic factor intervening in the apical lesion pathogenesis in Chagas' cardiopathy.

Challenges in the creation and development of a mathematics MOOC

The fast development of distance learning tools such as Open Educational Resources (OER) and Massive Open Online Courses (MOOC or MOOCs) are indicators of a shift in the way in which digital teaching and learning are understood. MOOC are a new style of online classes that allow any person with web access, anywhere, usually free of charge, to participate through video lectures, computer graded tests and discussion forums. They have been capturing the attention of many higher education institutions around the world. This paper will give us an overview of the “Introduction to Differential Calculus” a MOOC Project, created by an engaged volunteer team of Mathematics lecturers from four schools of the Polytechnic Institute of Oporto (IPP). The MOOC theories and their popularity are presented and complemented by a discussion of some MOOC definitions and their inherent advantages and disadvantages. It will also explore what MOOC mean for Mathematics education. The Project development is revealed by focusing on used MOOC structure, as well as the quite a lot of types of course materials produced. It ends with a presentation of a short discussion about problems and challenges met throughout the development of the project. It is also our goal to contribute for a change in the way teaching and learning Mathematics is seen and practiced nowadays, trying to make education more accessible to as many people as possible and increase our institution (IPP) recognition.

C4d Detection in Renal Allograft Biopsies: Immunohistochemistry vs. Immunofluorescence

Introduction. Peritubular capillary complement 4d staining is one of the criteria for the diagnosis of antibody-mediated rejection, and research into this is essential to kidney allograft evaluation. The immunofluorescence technique applied to frozen sections is the present gold-standard method for complement 4d staining and is used routinely in our laboratory. The immunohistochemistry technique applied to paraffin-embedded tissue may be used when no frozen tissue is available. Material and Methods. The aim of this study is to evaluate the sensitivity and specificity of immunohistochemistry compared with immunofluorescence. We describe the advantages and disadvantages of the immunohistochemistry vs. the immunofluorescence technique. For this purpose complement 4d staining was performed retrospectively by the two methods in indication biopsies (n=143) and graded using the Banff 07 classification. Results. There was total classification agreement between methods in 87.4% (125/143) of cases. However, immunohistochemistry staining caused more difficulties in interpretation, due to nonspecific staining in tubular cells and surrounding interstitium. All cases negative by immunofluorescence were also negative by immunohistochemistry. The biopsies were classified as positive in 44.7% (64/143) of cases performed by immunofluorescence vs. 36.4% (52/143) performed by immunohistochemistry. Fewer biopsies were classified as positive diffuse in the immunohistochemistry group(25.1% vs. 31.4%) and more as positive focal (13.2% vs. 11.1%). More cases were classified as negative by immunohistochemistry (63.6% vs. 55.2%). Study by ROC curve showed immunohistochemistry has a specificity of 100% and a sensitivity of 81.2% in relation to immunofluorescence (AUC: 0.906; 95% confidence interval: 0.846-0.949; p=0.0001). Conclusions. The immunohistochemistry method presents an excellent specificity but lower sensitivity to C4d detection in allograft dysfunction. The evaluation is more difficult, requiring a more experienced observer than the immunofluorescence method. Based on these results, we conclude that the immunohistochemistry technique can safely be used when immunofluorescence is not available.

Prototipagem de um sistema de gestão de armazém com recurso à identificação por radiofrequência

A evolução tecnológica atingiu um ritmo que muitas empresas têm dificuldade de acompanhar, existem diversas opções no mercado, para um mesmo objectivo, e tornasse determinante o processo de tomada de decisão sobre qual tecnologia adoptar para determinado objectivo. O alvo de estudo desta dissertação de mestrado, é uma das tecnologias, que últimamente tem ganho especial relevo, quando aplicada ao ambiente industrial, o RFID (Radio Frequency Identification Devices). Na presente dissertação, foi efectuado um levantamento do estado da arte, na área da identificação automática, com especial foco no RFID. Esta revisão bibliográfica teve como principal objectivo perceber quais as tecnologias concorrentes do RFID, e explorar quais as suas principais características tecnológicas e funcionais, bem como as vantagens no uso desta tecnologia de forma a sustentar a implementação de um sistema protótipo de gestão de armazém. O contributo final da dissertação, consiste numa aplicação que tem como principal objectvo simular os fluxos de infomação resultantes dos fluxos fisícos de materiais em ambiente de armazém. Foi também tido em conta no desenvolvimento da aplicação, a demonstração de algumas das mais valias que esta tecnologia pode trazer para a gestão de armazéns. Para implementação da aplicação destaca-se a utilização da arquitectura MVC (Model-view-controlador), em ambiente web, para permitir uma descentalização do software no ambiente indoor do armazém.

A família, uma estratégia para o sucesso escolar. Um estudo de caso com alunos do 2.º ano do 1.º CEB

O estudo que aqui apresentamos tem como objetivos estudar: o impacto do acompanhamento dos pais ou Encarregados de Educação no Estudo Autónomo e na realização dos Trabalhos de Casa, nos resultados escolares e na motivação para a escola e aprendizagens; ainda as necessidades sentidas pelos pais ou Encarregados de Educação ao fazerem este acompanhamento Neste estudo elaboramos seis propostas que planificamos, analisamos e, do seu desenvolvimento, tiramos as respetivas conclusões. As propostas foram dinamizadas pelo professor de turma e investigador em pequenas sessões/reuniões de esclarecimento com os pais ou Encarregados de Educação sendo quatro delas aplicadas num 2.º ano de escolaridade e as outras duas a um 3.º ano. Nas propostas do 2.º ano foram trabalhadas as frações e as estratégias de cálculo mental bem como foi dinamizado o projeto “Clube de Pais Leitores” e o “Concurso de Espantalhos” também aberto à comunidade educativa. Nas propostas do 3.º ano de escolaridade abordamos as propriedades da multiplicação, sua utilização no cálculo mental, a consolidação da operação divisão através do jogo do 24 e orientações para o Estudo Acompanhado e Trabalhos de Casa para auxiliar os pais ou Encarregados de Educação. Com a implementação destas tarefas, apresentamos os tipos de envolvimento parental solicitado por cada atividade, os benefícios para a família, aluno e professor, os sistemas envolvidos no processo de desenvolvimento da criança e os fatores que influenciaram negativamente na realização destas atividades. A implementação destas atividades foi feita seguindo uma metodologia qualitativa, inserida num contexto de um estudo de caso. Os participantes no estudo foram entrevistados com o objetivo de completar o estudo realizado através do seu feedback. Neste estudo fizemos uma revisão bibliográfica e abordámos o envolvimento dos pais ou Encarregados de Educação e famílias na escola numa perspetiva cronológica, a tipologia de envolvimento parental na escola, os sistemas que influenciam o desenvolvimento da criança e ainda uma referência aos benefícios para a comunidade educativa do envolvimento parental e familiar na escola. Através dos dados obtidos, pudemos verificar que o acompanhamento dos pais ou Encarregados de Educação no Estudo Autónomo e Trabalhos de Casa e nos projetos de turma traz bastantes benefícios para todos os elementos da comunidade educativa, sendo o aluno o mais beneficiado, e influenciado primariamente pela família em articulação com a escola e comunidade. Também verificamos que os pais ou Encarregados de Educação têm necessidades de estarem informados sobre conteúdos escolares e serem conhecedores das estratégias utilizadas na sala de aulas pelo que, sem isto, apresentam dificuldades em acompanharem os seus educados em casa. A realização deste estudo visa contribuir para a compreensão das necessidades sentidas pelos pais ou Encarregados de Educação no acompanhamento do Estudo Autónomo e Trabalho de Casa e as formas de dinamizar a cooperação entre o professor da turma e a família, promovendo o sucesso e a motivação escolar.

Perspectives of Identity in Julio Cortázar’s Rayuela

My aim was to produce a dissertation, based on Rayuela, which focuses on Cortázar’s questioning of identity. With this objective in mind, I have studied some of the salient elements in the novel that relate to this topic and the subsequent, interrelated, areas of study that arose in doing so. The cities of Paris and Buenos Aires are placed in contrast within the novel and reflect a dichotomy that reflects Oliveira’s condition as a “foreigner,” (more specifically as a South American in Europe). This duality is further reflected in Cortázar’s use of gender, and the development of the notions of active and passive, and an investigation into the traditional modes of thought, symbols, and stereotypes, and an open-ended questioning of their validity. These topics are framed by a notion of Judeo-Christian History that is in many ways flawed and, as such, contrasts with a more intuitive (or “oriental”) perception of reality, which is centred in figures such as la Maga. I found many explicit references to Zen philosophy, and related oriental references, that led me to believe that this area was worthy of further investigation. Rayuela is considered a classic novel within the canon of Spanish language literature. It’s famous “tabla,” like the rules for a game between the writer and the receptor that produce alternative readings, has led to many discussions regarding the novel’s structure and form, and also created a certain amount of polemic with the use of concepts such as the “lector hembra.” Many consider Cortázar a greater short story writer than a novelist, but nevertheless this novel had a profound effect on young readers upon its publication, much to Cortázar’s surprise, and continues to attract readers, dealing as it does with issues that continue to be relevant to many people.
