Conception and justification of a new test setup for assessment of the fatigue strength of connections between precast railway bridge girders

Important investments have been made worldwide in the modernization and construction of railway lines. Plans for new constructions, have also been laid out. Recently, precast concrete has been widely employed in the construction of railway bridges and viaducts. Several precast solutions have been applied, namely: I-shaped or U-shaped precast girders and uni-cellular or bi-cellular precast box girders. Regarding the structural scheme in the longitudinal direction, either simple span or continuous decks have been used. In this context, this work aims to contribute to the knowledge about the real performance of these structures through the development of a laboratory tests setup, for the study of this type of structure, focusing on the connection between the precast beams. The setup will be implemented at the Laboratory of Earthquake and Structural Engineering (LESE), several experimental campaigns on the cyclic behaviour of reinforced concrete elements have been carried out.6612-034D-AE05 | PEDRO DA SILVA DELGADON/

Caracterização dos ginastas de Teamgym a nível do perfil morfológico e da incidência de lesões

A investigação realizada tem como propósito determinar qual o perfil morfológico mais adequado a um atleta de Teamgym. Pretende-se aumentar a assertividade do processo de treino, sabendo que perfil morfológico os atletas deveriam atingir de acordo com as exigências e características da disciplina. Assim, estudou-se uma amostra de 85 atletas, entre os 9 e os 25 anos, dos escalões juniores e seniores, federados pelo Sporting Clube de Portugal. Foram registadas três formas diferentes de recolha de dados: bioimpedância, antropometria e questionário adaptado - Estudo sobre as lesões em Ginastas de Competição na Época de 2005/2006 (Oliveira, R., et al., 2007). As recolhas efetuadas permitiram obter o somatótipo e índice de massa corporal dos atletas; inquiri-los sobre o processo de treino a que são sujeitos; e averiguar a ocorrência de lesões na última época desportiva. Os dados obtidos mostram que embora o processo de treino não pareça estar organizado da melhor forma para fomentar uma adaptação morfológica, no escalão sénior elite os atletas são predominantemente mesomorfos, indo este somatótipo ao encontro da caracterização da disciplina. Conclui-se ainda que é mais difícil atingir esta morfologia no sexo feminino, tendo estas maior incidência de lesão.The main focus on this research is to determine the most suitable morphological phenotype to a Teamgym athlete. Knowing which morphological phenotype athletes should reach according to the requirements and characteristics of the discipline, it’s intended to increase the assertiveness of training process. The sample used is a group of 85 gymnasts from Sporting Clube de Portugal, ages between 9 and 25, junior and senior levels. It was recorded three different forms of data collection: bioimpedance, anthropometry and questionnaire - Study about injuries in Gymnasts Competition in the season of 2005/2006 (Oliveira, R., et al., 2007). With these data I was able to determinate somatotype and body mass index of athletes; inquired them about their training process; and investigate the occurrence of injuries in the last sports season. I came to the conclusion that although the training process appears not to be organized in the best way to foster a morphological adaptation, senior elite level athletes are predominantly mesomorph, somatotype that is going to meet the characteristics of the sport. Other conclusions are the diferences between men and women at achieve this morphology. Women have much more difficulty achieving mesomorph somatotype, they have higher incidence of injury

O pensamento orquestral no treino auditivo de um pianista

Um dos pontos frágeis da aprendizagem do nível complementar de piano em Portugal revela-se na separação das componentes práticas e artísticas. Ou seja, muitas vezes para conseguir produzir passagens rápidas e/ou uniformes, os alunos persistem em repetições mecânicas sem pensar no objetivo específico de produzir um som musical; consequentemente a fertilidade da imaginação auditiva é posto ao lado e a exploração da paleta dinâmica-tímbrica instrumental fica como uma meta futura que dificilmente chega a ser concretizada. Este projeto propõe o exercício do pensamento orquestral como meio para alcançar uma interpretação mais creativa e personalizada.One of the fragile aspects of piano learning within the elder Conservatory students in Portugal is demonstrated by the separation between practical and artistic components. By this I mean they persist on mechanical repetitions without thinking of the specific goal of producing a musical sound. Consequently the fertility of the auditive imagination is kept aside and the exploration of the timbre-dynamic spectrum hardly get’s accomplished. This Project proposes the exercise of the orchestral thinking has a way of reaching a more creative and personalized interpretation.Mestrado em Ensino de Músic

Objective: To report oral health education strategies for biofilm control in a child with a neurodevelopmental disorder. Case report: A 9-year-old boy with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) was presented at the dental clinic with extreme difficulties in the oral hygiene practice. The intraoral examination revealed a massive presence of dental biofilm, moderate gingivitis, and caries experience. An individualized educational strategy using visual pedagogy added an adapted toothbrush was implemented. The improvement in the simplified oral hygiene indexes and gingival bleeding index demonstrated the success of this intervention. Conclusion: The individualized educational strategies can be successful implemented in a child with ASD and ADHD

Genetic structure of the casein in Serrana Transmontana goats

Goat's milk is considered dietary and closer to the human’s1. The yield of its transformation into cheese is conditioned by protein and lipid composition of milk2-4 and in a thinner way, the proportions in which different proteins contribute to the formation of the whole protein fraction. The ability of coagulation is directly related to a structured clot on which will depend the renneting yield and final texture of the cheese5. The Serrana breed is considered the best for milk purpose and is the largest national herd. Currently has four ecotypes: Ribatejana, Transmontana, Jarmelista and Serra6. The genetic structure of a population, presenting higher frequency of favorable genes, is crucial in the definition of production purpose.PRODER–Medida 4.1–PA23881info:eu-repo/semantics/publishedVersio

The AMBRE Project: searching for the closest solar siblings

Finding solar siblings, that is, stars that formed in the same cluster as the Sun, will yield information about the conditions at the Sun's birthplace. We search for solar sibling candidates in AMBRE, the very large spectra database of solar vicinity stars. Since the ages and chemical abundances of solar siblings are very similar to those of the Sun, we carried out a chemistry- and age-based search for solar sibling candidates. We used high-resolution spectra to derive precise stellar parameters and chemical abundances of the stars. We used these spectroscopic parameters together with Gaia DR2 astrometric data to derive stellar isochronal ages. Gaia data were also used to study the kinematics of the sibling candidates. From the about 17000 stars that are characterized within the AMBRE project, we first selected 55 stars whose metallicities are closest to the solar value (-0.1 < [Fe/H] < 0.1 dex). For these stars we derived precise chemical abundances of several iron-peak, alpha- and neutron-capture elements, based on which we selected 12 solar sibling candidates with average abundances and metallicities between -0.03 to 0.03 dex. Our further selection left us with 4 candidates with stellar ages that are compatible with the solar age within observational uncertainties. For the 2 of the hottest candidates, we derived the carbon isotopic ratios, which are compatible with the solar value. HD186302 is the most precisely characterized and probably the most probable candidate of our 4 best candidates. Very precise chemical characterization and age estimation is necessary to identify solar siblings. We propose that in addition to typical chemical tagging, the study of isotopic ratios can give further important information about the relation of sibling candidates with the Sun. Ideally, asteroseismic age determinations of the candidates could solve the problem of imprecise isochronal ages.Comment: Accepted for publication in A&
