O potencial de produção e comercialização de uvas "D. Maria" em Portugal

A produção de uva de mesa “Dona Maria”, casta 100% nacional criada e obtida nos anos 50 na antiga Estação Agronómica Nacional, em Oeiras, pelo engenheiro-agrónomo Leão Ferreira de Almeida, vem decrescendo ano após ano como resultado do desinteresse e abandono por parte dos agricultores. É uma uva muito doce, com bagos grandes e apreciada pelos portugueses que sentem cada vez mais dificuldades em encontrá-la no mercado. Este estudo de caso tem como objetivos verificar o porquê de tão pouca produção desta uva por parte dos agricultores e sugerir através de ferramentas e estratégias de marketing formas de fazer com que a uva seja mais conhecida e consumida pelo mercado português. No intuito de valorizar e consumir o que é nacional, a uva “Dona Maria” é uma excelente opção para o consumo em fresco ou na forma de passa, em cantinas de escolas e universidades. Os investimentos em novas tecnologias de produção e investigação por parte dos produtores também são uma boa opção para rentabilizar a casta e fazer com que ela não desapareça do mercado, o que seria desastroso na perspectiva cultural e económica; ### Abstract: The production of the table grape “Dona Maria”, a 100% national Portuguese grape variety, created and produced in the 1950s in the former National Agricultural Station (EAN) in Oeiras, Portugal, by Leão Ferreira de Almeida, has been decreasing year after year as a result of lack of interest and abandonment on behalf of producers. It is a very sweet grape with big berries and is highly appreciated by the Portuguese, who find it ever more difficult to find it in the marketplace. This case study´s objectives were to investigate the shortage of production by growers, and to suggest through marketing strategies and tools, ways to make this grape better known and more consumed by the Portuguese market. Within the scope of highlighting and promoting this national product, “Dona Maria” grape is an excellent option either as a fresh consumable or raisin in school and university restaurants. Investment in new production technologies and research are also a good choice and direction to promote the variety and avoid its disappearance from the market, which would be disastrous both culturally and economically.

Relatório da prática de ensino supervisionada na Escola Básica 2, 3/S Cunha Rivara, Arraiolos

O presente relatório tem como objetivo a explanação e a discussão de forma concisa da atividade docente desenvolvida no ano letivo 2012/2013, na Escola Básica 2,3/S Cunha Rivara de Arraiolos com as turmas do 8.º C e 11.º D nas disciplinas de Ciências Naturais e Saúde respetivamente, sob a orientação da Doutora Marília Cid. Apresentam-se os fundamentos teóricos que sustentaram o delineamento de todas as metodologias e estratégias de ensino no sentido de promover situações de aprendizagem significativa aos alunos das turmas referidas. Este é também um testemunho da participação ativa no projeto de educação para a saúde em colaboração com as entidades promotoras de saúde no Concelho de Arraiolos no sentido de organizar atividades extracurriculares propiciadoras da aprendizagem nesta dimensão, com a dinamização de sessões de esclarecimento de Educação Sexual a várias turmas da escola e a produção de um website informativo e de apoio aos alunos do 3.º Ciclo do Ensino Básico e do Ensino Secundário sobre Educação Sexual. Foi apanágio deste trabalho a análise e reflexão também evidenciadas no trabalho de investigação sobre as atividades desenvolvidas no âmbito da Educação para a Saúde mas também em toda a atividade de lecionação. Esta análise e reflexão, bem como a pesquisa individual e o trabalho colaborativo permitiram o desenvolvimento progressivo das minhas capacidades, da qualidade do trabalho desenvolvido e o melhoramento da formação académica. /ABSTRACT: This report aims at explaining concisely and discussion of teaching developed in the academic year 2012/2013, at Escola Básica 2,3 / S Cunha Rivara in Arraiolos with classes C from 8th grade class and D from 11th , in the disciplines of Natural Sciences and Health respectively under the guidance of PhD Teacher Marilia Cid. Here we present the theoretical foundations that supported the design of all methodologies and teaching strategies to promote meaningful learning situations for students of classes above. This is also a testament to the active participation in the design of health education in collaboration with the health promoters in the County of Arraiolos to organize extracurricular activities conducive learning these dimensions, the organization of information sessions to various Sex Education school classes and the production of an informational website to support the students of the 3rd cycle and Secondary Education on Sexual Education. It was the hallmark of this work, analysis and reflection evidenced in research work on the activities within the Health Education but also of the entire teaching activity. This analysis and reflection as well as individual research and collaborative work allowed the progressive development of my abilities, quality of work and the improvement of academic training.

The Traceless Oldroyd viscoelastic model

In the traceless Oldroyd viscoelastic model, the viscoelastic extra stress tensor is decomposed into its traceless (deviatoric) and spherical parts, leading to a reformulation of the classical Oldroyd model. The equivalence of the two models is established comparing model predictions for simple test cases. The new model is validated using several 2D benchmark problems. The structure and behavior of the new model are discussed and the future use of the new model in envisioned, both on the theoretical and numerical perspectives.

UT Austin | Portugal Workshop on Nonlinear Mechanics and Applications in Life Sciences

This is a CoLab Workshop organized as an initiative of the UT Austin | Portugal Program to reinforce the Portuguese competences in Nonlinear Mechanics and in complex problems arising from applications to the mathematical modeling and simulations in the Life Sciences. The Workshop provides a place to exchange recent developments, discoveries and progresses in this challenging research field. The main goal is to bring together doctoral candidates, postdoctoral scientists and graduates interested in the field, giving them the opportunity to make scientific interactions and new connections with established experts in the interdisciplinary topics covered by the event. Another important goal of the Workshop is to promote collaboration between members of the different areas of the UT Austin | Portugal community.

A traceless variant of the Johnson-Segalman viscoelastic model
