Musicalidade em crianças com idade pré-escolar

Relatório Final de Prática de Ensino Supervisionada do Mestrado em Educação Pré-escolar apresentado na Escola Superior de Educação do Instituto Politécnico de Viana do CasteloO presente estudo foi realizado no âmbito da Unidade Curricular de Prática de Ensino Supervisionada II integrada no Mestrado em Educação Pré-Escolar. Este projeto envolveu 25 crianças com idades entre os 4 e 6 anos de uma sala de um jardim-de-infância pertencente ao concelho de Viana do Castelo. Durante o projeto, foram estudados temas que mostraram ser fundamentais para a compreensão das bases teóricas para este estudo, tais como, a importância da Expressão Musical, a consciência musical nas crianças de idade pré-escolar, e das primeiras manifestações da música às metodologias de ensino musical nos dias de hoje. Suportando a escolha da temática a trabalhar neste projeto, estão as necessidades encontradas através das observações realizadas durante a PES I. Através da observação efetuada, foram identificados alguns aspetos que poderiam ser melhorados, entre os quais está a frequência que as crianças estavam em contacto com atividades do domínio da Expressão Musical. Este estudo está dividido em três partes diferentes, na qual a primeira parte apresenta o contexto educativo, tratando de todos os aspetos que devem ser tidos em conta para fazer uma devida contextualização acerca deste projeto e do local que teve incidência. Na segunda parte vão estar presentes os aspetos mais relacionados com o projeto, tais como, a perspetiva teórica de alguns autores acerca das temáticas estudadas, a metodologia adotada no trabalho de investigação, sendo ela o trabalho de projeto assente no paradigma qualitativo, a análise e interpretação de resultados e conclusões retiradas no trabalho desenvolvido. Este projeto dividiu-se em 7 atividades diferentes, que decorreram durante a PES II, e durante a planificação e implementação destas, foram tidas em conta as necessidades das crianças, assim como todos os objetivos traçados para a realização deste estudo. A terceira parte do relatório está contemplada uma reflexão global da PES, onde é feita uma análise de todo o percurso. Refletindo sobre todo o trabalho desenvolvido, verificou-se uma grande evolução das capacidades musicais que as crianças tinham, colocando em prática os conhecimentos retidos nas diferentes atividades, facilitando todo o decorrer do projeto e capacitando a recolha e análise de dados.The present study was performed under the subject Supervised Teaching Practice II (STP II), integrated in the Master of Preschool Education. In this project were involved 25 children, with ages between 4 and 6 years old which were part of a Kindergarten room, located in Viana do Castelo’s county. During the project, some themes were studied that revealed being crucial for understanding the theorical basis within this study, such as, the relevance of Musical Expression, the musical awareness of preschool children, and since the first manifestation of music to nowadays music teaching methodologies. Behind the selection of the theme to work in this project, are the needs found through the observations made during the STP I. During the observations were found some points that could and should be improved and the frequency that the Musical Expression was worked out was the one that pointed out. This study is divided in three different parts, in which the first part presents the educational context, treating all the aspects that should be taken in account to do a proper contextualization about this project and the place that it had incidence. The second part of the study will have the most revealing points that are related with the project, such as, the theorical perspective of some authors about the themes studied, the methodology adopted during the investigation work, that was a project work based on qualitative paradigm, the analysis and interpretation of the results and the conclusions of all the work developed. This project is divided into 7 different activities, which took place during the STP II, and during the planning and performing of them, were taken in account all the needs of the children, as well as all the goals planned to the accomplishment of this project. The third part contains a global reflection about the STP, where is done an analysis of all the course of the project. Prospecting all the work that has been done, we could see a great improvement of musical capacities of the children, applying all the concepts obtained on the different activities, facilitating all the course of the project and capacitating the data collection and analysis

Whole grain bread preserved with lemon juice: a comparative study / Pão integral conservado com suco de limão: um estudo comparativo

The use of natural substances for the replacement of chemicals in food conservation is a global trend. Thus, the aim of this study was to evaluate the effect of lemon juice on wholemeal bread conservation and determine shelf time. This is a quantitative, laboratory and explanatory study in which three formulas of the dough with the same composition of ingredients were tested. One formula had the addition of lemon juice at the concentration of 1.75%; other with industrial antifungal at 1.0%; and the last formula without any addition. Analysis of fibers, humidity, pH and titratable acidity were performed. Shelf life for all formulations was evaluated by the visual method until the formation of mold colonies for 5 days. The samples showed similarity in the variation in humidity level (32.4 to 37.9) in relation to time, having a reduction at the first moment and then in the increase of F1 and F2, and F3 remained constant. The  fiber content of the formulations showed a discrepancy between the contents of the evaluated times. The pH of the three formulas was within the desirable range of 4.0 to 7.0 ensuring good quality for the product according to the technical pattern of baking. The acidity variation between formulas followed a common pattern. Shelf life was similar for formulas containing lemon juice and antifungal solution, however the formula without any addition had the shortest shelf time, confirming the efficiency of lemon in the conservation of wholemeal bread.

EFEITO DO TEMPO DE CONSOLIDAÇÃO NAS PRESSÕES HORIZONTAIS EXPERIMENTAIS E NORMATIZADAS EM SILOS VERTICAIS

The study of the pressures that the stored product exerts on the silo walls is a relevant factor, the present work has the objective of determining, empirically and experimentally, the loading and unloading pressures along the circular section of the vertical metal silo exerted by the stored product and the influence of the consolidation time. For the determination of horizontal and frictionpressures, devices composed of pairs of load cells were used, fixed to square sections of the silo of the silo with 2.5 m of body height and 0.64 m of internal diameter and tremonha with 0.51 m height and inclination of approximately 60° with the horizontal, made of smooth steel with 1 mm thickness. The corn loading and unloading tests were in quintupleata, and three consolidation times were adopted, which were 6, 12 and 24 hours. The experimentally determined pressures were compared to the values found from the equations contained in the standards AS 3774 (1990) and BS EN 1991/4 (2006). It was evidenced that the experimental data of horizontal pressure during loading were always lower than those standardized, considering that the standards increase the values due to the use of safety coefficients and although the calculations were performed with the subtraction of this coefficient, no interference of the consolidation times analyzed in the pressures was observed.El estudio de las presiones que el producto almacenado ejerce sobre las paredes del silo es un factor relevante, el presente trabajo tiene el objetivo de determinar, empírica y experimentalmente, las presiones de carga y descarga a lo largo de la sección circular del silo metálico vertical ejercido por el producto almacenado y la influencia del tiempo de consolidación. Para la determinación de las presiónes horizontales y de fricción, se utilizaron dispositivos compuestos por pares de células de carga, fijadas a secciones cuadradas del silo del silo con 2,5 m de altura del cuerpo y 0,64 m de diámetro interno y tremonha con 0,51 m de altura e inclinación de aproximadamente 60° con la horizontal, fabricado en acero liso de 1 mm de espesor. Las pruebas de carga y descarga de maíz fueron en quintupleata, y se adoptaron tres tiempos de consolidación, que fueron de 6, 12 y 24 horas. Las presiones determinadas experimentalmente se compararon con los valores encontrados a partir de las ecuaciones contenidas en las normas AS 3774 (1990) y BS EN 1991/4 (2006). Se evidenció que los datos experimentales de presión horizontal durante la carga fueron siempre inferiores a los estandarizados, considerando que los estándares aumentan los valores debido al uso de coeficientes de seguridad y aunque los cálculos se realizaron con la sustracción de este coeficiente, no se observó interferencia de los tiempos de consolidación analizados en las presiones.O estudo das pressões que o produto armazenado exerce nas paredes do silo é um fator relevante, o presente trabalho possui o objetivo de determinar, empírica e experimentalmente, as pressões de carregamento e descarregamento ao longo da seção circular do silo vertical metálico exercidas pelo produto armazenado e a influência do tempo de consolidação. Para a determinação das pressões horizontais e de atrito, foram utilizados dispositivos compostos por pares de células de carga, fixados a seções quadradas do silo da parede lisa do silo com 2,5 m de altura de corpo e 0,64 m de diâmetro interno e tremonha com 0,51 m de altura e inclinação de aproximadamente 60° com a horizontal, confeccionados em aço liso com 1 mm de espessura. Os ensaios de carregamento e descarregamento do milho foram em quintuplicata, sendo adotados três tempos de consolidação sendo estes de 6, 12 e 24 horas. As pressões determinadas experimentalmente foram comparadas aos valores encontrados á partir das equações contidas nas normas AS 3774 (1990) e BS EN 1991/4 (2006). Foi evidenciado que os dados experimentais de pressão horizontal durante o carregamento foram sempre inferiores aos normatizados, tendo em vista que as normas majoram os valores devido a utilização de coeficientes de segurança e embora realizado os cálculos com a subtração deste coeficiente, não foi observado interferência dos tempos de consolidação analisados nas pressões

Exercise training improves quality of life in women with subclinical hypothyroidism : a randomized clinical trial.

Objective: The aim was to evaluate the quality of life (HRQoL) in women with subclinical hypothyroidism (sHT) after 16 weeks of endurance training. Subjects and methods: In the first phase, a cross-sectional study was conducted in which 22 women with sHT (median age: 41.5 (interquartile range: 17.5) years, body mass index: 26.2 (8.7) kg/m2 , thyroid stimulating hormone > 4.94 mIU/L and free thyroxine between 0.8 and 1.3 ng/dL were compared to a group of 33 euthyroid women concerned to HRQoL. In the second phase, a randomized clinical trial was conducted where only women with sHT were randomly divided into two groups: sHT-Tr (n = 10) ? participants that performed an exercise program ? and sHT-Sed (n = 10) ? controls. Exercise training consisted of 60 minutes of aerobic activities (bike and treadmill), three times a week, for 16 weeks. The HRQoL was assessed by the SF-36 questionnaire in the early and at the end of four months. Results: Women with sHT had lower scores on functional capacity domain in relation to the euthyroid ones (77.0 ? 23.0 vs. 88.8 ? 14.6; p = 0.020). The sHT-Tr group improved functional capacity, general health, emotional aspects, mental and physical component of HRQoL after training period, while the sHT-Sed group showed no significant changes. Conclusion: After 16 weeks of aerobic exercise training, there were remarkable improvements in HRQoL in women with sHT

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
