A estética representa uma qualidade cada vez mais requisitada pela sociedade na atualidade. A busca pela aparência ideal expandiu-se também na medicina dentária, aumentando as exigências por resultados perfeitos. A medicina dentária tem desenvolvido novas técnicas e novos materiais com a ambição de reproduzir as propriedades estéticas e funcionais dos dentes naturais. Os sistemas totalmente cerâmicos têm sido alvo de grande entusiasmo dado as suas características inerentes. O seu potencial na reabilitação oral estética tem derrotado as suas antecessoras metalocerâmicas. À semelhança do esmalte e da dentina, os sistemas totalmente cerâmicos exibem boas propriedades óticas de translucidez, opacidade, fluorescência e opalescência, resultado da interação com a luz. Ainda que não seja possível dissociar as propriedades óticas das propriedades mecânicas de um dente natural para o sucesso de uma restauração, a heterogeneidade das cerâmicas têm sido exitosas enquanto sistema que combina diferentes propriedades para diferentes indicações clínicas. Esta variabilidade deve-se a diferentes composições químicas e a diferentes processos de fabricação, entre outros, que acentuam ou atenuam qualidades em cada sistema totalmente cerâmico. Este trabalho pretende abordar e comparar os sistemas cerâmicos atuais (cerâmicas com base em sílica, cerâmicas com base de alumina, cerâmicas com base em zircónia) de acordo com as suas propriedades óticas e a consequente aplicação clínica tendo em conta as características dos dentes naturais.

Graphene has emerged as an extraordinary material with its capability to accommodate an array of remarkable electronic, mechanical and chemical properties. Extra-large surface-to-volume ratio renders graphene a highly flexible morphology, giving rise to intriguing observations such as ripples, wrinkles and folds as well as the potential to transform into other novel carbon nanostructures. Ultra-thin, mechanically tough, electrically conductive graphene films promise to enable a wealth of possible applications ranging from hydrogen storage scaffolds, electronic transistors, to bottom-up material designs. Enthusiasm for graphene-based applications aside, there are still significant challenges to their realization, largely due to the difficulty of precisely controlling the graphene properties. Controlling the graphene morphology over large areas is crucial in enabling future graphene-based applications and material design. This dissertation aims to shed lights on potential mechanisms to actively manipulate the graphene morphology and properties and therefore enable the material design principle that delivers desirable mechanical and electronic functionalities of graphene and its derivatives.

Certain environments can inhibit learning and stifle enthusiasm, while others enhance learning or stimulate curiosity. Furthermore, in a world where technological change is accelerating we could ask how might architecture connect resource abundant and resource scarce innovation environments? Innovation environments developed out of necessity within urban villages and those developed with high intention and expectation within more institutionalized settings share a framework of opportunity for addressing change through learning and education. This thesis investigates formal and informal learning environments and how architecture can stimulate curiosity, enrich learning, create common ground, and expand access to education. The reason for this thesis exploration is to better understand how architects might design inclusive environments that bring people together to build sustainable infrastructure encouraging innovation and adaptation to change for years to come. The context of this thesis is largely based on Colin McFarlane’s theory that the “city is an assemblage for learning” The socio-spatial perspective in urbanism, considers how built infrastructure and society interact. Through the urban realm, inhabitants learn to negotiate people, space, politics, and resources affecting their daily lives. The city is therefore a dynamic field of emergent possibility. This thesis uses the city as a lens through which the boundaries between informal and formal logics as well as the public and private might be blurred. Through analytical processes I have examined the environmental devices and assemblage of factors that consistently provide conditions through which learning may thrive. These parameters that make a creative space significant can help suggest the design of common ground environments through which innovation is catalyzed.

This paper is part of the Project “Adaptive thinking and flexible computation: Critical issues”. In this paper we discuss different perspectives of flexibility and adaptive thinking in literature. We also discuss the idea of proceptual thinking and how this idea is important in our perspective of adaptive thinking. The paper analyses a situation developed with a first grade classroom and its teacher named the day number. It is a daily activity at the beginning of the school day. It consists on to look for the date number and to think about different ways of writing it using the four arithmetic operations. The analyzed activity was developed on March 19, so the challenge was to write 19 in several ways. The data show the pupils’ enthusiasm and their efforts to find different ways of writing the number. Some used large numbers and division, which they were just starting to learn. The pupils presented symbolic expressions of 19, decomposing and recomposing it in a flexible manner.

O tema surgiu pela necessidade de saber mais sobre o trabalho do professor bibliotecário, função bastante recente, e compreender aquilo que poderá ser o seu desempenho enquanto animador de leitura. Por outro lado, quisemos verificar se, o espaço da biblioteca escolar estava se constitui num espaço onde se desenvolve adequadamente e consolida hábitos de leitura, não só através do professor bibliotecário mas da parceria deste com outros professores, para que haja interacção necessária no sentido de melhor desenvolver a aprendizagem dos alunos, durante o processo educativo das crianças. Sendo estas algumas das nossas maiores preocupações, um dos aspectos que quisemos conhecer foram as estratégias de dinamização da Hora do Conto desenvolvidas por estes professores. Outro ponto importante, consiste em verificar se a animação da leitura é conduzida para que os alunos se sintam motivados a ouvir uma história, bem como com a preocupação de fazer com que os alunos aprendam a gostar de ler e produzir sentido a partir do que lêem. Assim, apontamos para aspectos importantes acerca da função exercida pelo professor bibliotecário e o professor titular de turma, ora questionando, ora indicando acerca do desempenho, ora tentando compreender o perfil de cada um deles, visto que ocupam lugares simbólicos distintos. Possivelmente, a animação da Hora do Conto, ainda, se constitui como um desafio para os professores de maneira geral e, em especial, para o professor bibliotecário. v Então, consideramos de suma importância a observação da dinamização da Hora do Conto, pois, que é na acção que se pode produzir significados para novas abordagens teóricas. Desta forma, o nosso trabalho consistiu principalmente em tentar perceber como o professor bibliotecário e o professor titular de turma animam o momento da Hora do Conto, isto é, que “alma” emprestam às histórias neste momento que é de formação de leitores. Além disso, consideramos importante observar se os alunos apreciam positivamente a Hora do Conto e se ficam satisfeitos com a dinamização aí realizada, bem como com a leitura proporcionada tanto no contexto de sala de aula como de biblioteca. As nossas bases metodológicas foram sustentadas através de entrevistas, questionários e observação. Para tal, seguimos orientações de autores como, Bardin, Campenhoudt e Quivy, entre outros. Apoiamo-nos teoricamente em alguns dos principais autores contemporâneos que tratam do assunto como Bogdan e Biklen. Finalmente, norteados por alguns autores que se destacam nos estudos acerca da leitura e da pedagogia da leitura, tentamos analisar o que para nós é de fundamental importância, naquilo que se refere à Animação da Hora do Conto, ou seja, como agem o professor titular e o professor bibliotecário quando se propõe a formar leitores, e que formação possuem para dinamizarem a Hora do Conto de forma eficaz, sensível e significativa.

The aim of this present work is investigating the interest and motivation for learning, awakened in pupils when the educator practice is guided by the ethnomathematics perspective. The main question is: Can an ethnomathematic approach awaken enthusiasm in pupils, causing it to become more critic and active in building their knowledge? The methodology that guides the investigation is qualitative, based on technical arising of the ethnographic case study. Theoretical contributions that support the investigation are from the scientific methodology and from ethnomathematics. The research material is composed by: researcher’s field diary, audio recording of participant observation, interviews reports of community residents and students parents, highlighting the material produced by students. This study was developed on an 8º year of high school of rural community. During the work were prioritized the ethnomathematics concepts of the Ethnomathematic Program, which establish a link exchange, where the lecturers inserts themselves on the reality of pupils in a way that promote an appreciation of their identity and a commitment to their learning. The educator investigates and values the ideas of pupils throughout dialogues. There are challenges for the application of education with ethno mathematic perspective, pointed out by authors, listed and supplemented in the research. In this context, it is believed that the socio-cultural knowledge must be respect, and as they are understood their specialties, capabilities and characteristics, this can guide teaching practice, making significant process for pupils, providing appropriation of scientific knowledge. Analysis of research practice indicated that students, research subjects, when they decided contextual issues, with their way of life, felt appreciated. The conclusion is that, with continuous action of contextualized of school mathematics, from the recognition of the environment and of cultural identity, the educator has the opportunity of review their own participant condition, and therefore promote an enthusiasm for learning. Because a motivated pupil becomes active, since that the all project is guided in a significant theme.

E-learning is a vision that has sparked a wide-ranging enthusiasm for moderators, course designers and learners. Asynchronous conferencing is currently central to this vision. Some educators assume that supporting learners who use this medium is the same as supporting them in the classroom. However, this is not the case. This paper outlines the current research into providing signposts that enable us to improve the training and support offered to new e-moderators and e-course designers. It suggests a classification of roles and tasks that together with an e-course framework will help to maximize the benefits of e-learning and enable all participants to migrate successfully to the new environment.

VIOLA MUSIC FROM THE AMERICAS: MUSIC FROM CANADA, UNITED STATES, CUBA, VENEZUELA, MEXICO, AND BRAZIL
Resumo:
The enthusiasm towards writing music for the viola that flourished in the early 1900’s thanks to the efforts of a number of twentieth-century violists and composers rapidly spilled over to North and South America. Viola works by American and Canadian composers have already become cornerstones of the viola repertoire worldwide. On the other hand, compositions from other parts of the American continent remain lesser known outside of their country of origin. This is due in part to the less developed publishing and recording industry in these countries which makes it difficult for performers and programmers from other countries to buy or rent performing materials. As a violist born and trained in Venezuela, performing works by important Latin American composers to new audiences is deeply important to me. This dissertation was completed by performing selected works by Canadian, American, Cuban, Mexican, Brazilian, and Venezuelan composers. Composers from these countries have mixed their rich musical traditions with modern compositional techniques, creating original works that have greatly enriched the viola repertoire. This eclectic mixture of styles makes the music from Latin American composers not only very different from that of American and Canadian composers, but also very different from those of their neighboring countries. Through my three dissertation recitals, I intend to share this music with new audiences and inspire other violists to become familiar with this repertoire. The first recital includes compositions by American composers George Rochberg (1918-2015), Elliott Carter (1908-2012), and Alan Shulman (1915-2002) and Canadian composer Elizabeth Raum (b. 1945). The second recital includes works by Cuban composers Cesar Orozco (b. 1980), and Keyla Orozco (b. 1969), Venezuelan composers Aldemaro Romero (1928-2007) and Modesta Bor (1926-1998), and Venezuelan-Uruguayan composer Efrain Oscher (b. 1974). The third recital includes works by Mexican composers Carlos Chavez (1899-1978), José Pablo Moncayo (1912-1958) and Manuel M Ponce (1882-1948), and Brazilian composers Francisco Mignone (1897-1986) and Brenno Blauth (1931-1993). This music represents a bouquet of a distinctive mixture of styles from different parts of the American continent. Recordings of all three recitals can be accessed at the University of Maryland Hornabake Library.

A popularidade das séries televisivas que abordam as Ciências Forenses (CSI 1 Mentes Criminosas, Casos Arquivados...) permite construir actividades que envolvem os alunos numa exploração científica de modo a que dominem os conceitos e apreciem a natureza da Ciência. Estes recursos educativos aplicam uma abordagem Ciência Tecnologia-Sociedade -Pensamento Crítico (CTS-PC) e podem ser explorados segundo uma metodologia de Aprendizagem Baseada na Resolução de Problemas (ABRP). Neste trabalho são propostas actividades laboratoriais, a decorrer no contexto formal das aulas da disciplina de Física e Química A (FQ·A), utilizando sensores e a calculadora gráfica. Num contexto não-formal, e baseadas nas técnicas analíticas utilizadas em Ciências Forenses, foram desenvolvidas actividades para um Clube de Ciência ou Laboratórios Abertos, complementadas por um blogue (CSI-Mafra). Estes recursos foram posteriormente partilhados com outros professores de Física e Química, numa acção de formação, proposta pela autora, e cujo objectivo principal foi a diversificação das estratégias de ensino e aprendizagem. O entusiasmo dos alunos na realização das tarefas propostas e os resultados nos questionários de grau de satisfação e de opinião, aplicados a alunos e professores, sugere que as actividades desenvolvidas podem contribuir na motivação dos alunos para o estudo da Física e da Química e promover a literacia científica da comunidade escolar. ABSTRACT; The high popularity between teenagers of the television series that have Forensic Sciences and Criminal lnvestigations as central theme, such as CSI, Dexter, Criminal Minds and Cold Case, can be used to develop learning activities that involves the students into a scientific exploration which aim is leading the students to learn Chemistry and Physics with pleasure, motivation and curiosity. The educational resources developed in this thesis make use of the strategy Science-Technology-Society-Critical Thinking (STS-CP) and can be exploited according the teaching methodology Problem Based Learning (PBL). ln this work we propose a number of laboratory activities that can be used on the classes of the High School course Physic and Chemistry A (FQ-A) and a different set of activities to be used in a non-formal teaching environment, which are based on the analytical techniques used in Forensic Sciences. The non-formal activities were developed as part of the activities of a Science Club and complemented with an interactive blog. The teaching resources developed by us were also used in a professional training course to physics and chemistry teachers aimed to teach how to introduce new teaching learning strategies. The enthusiasm of the students shown during the activities and the extremely positive results of the questionnaires, applied to students and teachers after the activities, clearly indicates that the learning resources developed in this thesis contribute to the student's motivation to learn Physic and Chemistry and to promote the scientific Iiteracy of the scholar community.
