Configurando um AVO (Ambiente Virtual Anise de Abreu Gonçalves D'Orange Ferreira de Orientação): instrumentação de um professor em proposta de incentivo ao uso de TIC e AVA no nível de pós-graduação

In this paper, I will present a proposal for teachers’instrumentation in ICT by the configuration of a virtual learningenvironment (MOODLE) for advising Linguistics graduate students’projects on teacher education and language teaching mediated by digitaltechnologies. The context of the proposal is teaching as work,occasioned by an announcement from the IHE to encourage the use ofICT. Following the theoretical assumptions adopted by the ALTERresearch group, and confronted with the goals set in the text of theannouncement, the instrumentation involved the reorganization ofcontents provided by a graduate course in the research process steps:planning, implementation and dissemination, and of the artifactsaffordances: information, communication and production.

Adesivos multi-uso-avaliação da resistência adesiva a dentina frente a teste de cisalhamento, estereomicroscopia e microscopia eletrônica de varredura

Recent bonding systems have been advocated as multi-purpose bonding agents. The aim of this study was to determine if some of these bonding systems could be associated to composite resins from different manufacturers. This investigation was conducted to test lhe shear bond strength of three bonding systems: Scotchbond Multi-Purpose (3M Dental Products), Optibond Light Cure (Kerr) and Optibond Dual Cure (Kerr), when each of them was associated to lhe composite resins: Z1 00 (3M Dental Products), Prisma - APH (Dentsply) and Herculite XRV (Kerr). Seventy-two flat dentin bonding sites were prepared to 600 grit on human premolars mounted using acrilic resins. The teeth were assigned at random to 9 groups of 8 samples each. A split die with a 3mm diameter was placed over lhe surface of lhe dentin treated with one of lhe adhesive systems, and lhe selected composite resin was inserted and light cured. The split mold was removed and all samples were termocycled and stored in 37ºC water for 24 hours before testing. Shear bond strength was determined using an lnstron Universal testing machine. Some failures were examined under lhe S.E.M. Data was analysed by one-way analysis of variance, that demonstrated a significant difference (p<0,05) in the mean shear bond strength among Optibond Light Cure (15,446 MPa), Scotchbond Multi-Purpose (13,339 MPa) and Optibond Dual Cure (10,019 MPa). These values did not depend on the composite resin used. The association between bonding system/composite resin was statistycally significant (p<0,05) and the best results were obtained when the composite resins Z100 and Herculite were used with the adhesive system Optibond Light Cure, and when the composite resin APH was used with the adhesive system Scotchbond Multi-Purpose

Avaliação do selamento de ápices radiculares retrobturados ou recobertos com diferentes materiais mediante infiltração marginal por corante e análise da interface em microscopia eletrônica de varredura

The purpose of this study was to evaluate the apical sealing ability and the marginal adaptation of five dental materials used in retrofillings or applied to the bevelled root surface. One hundred and forty extracted single rooted human teeth were used, divided into seven groups of twenty each. ln the first, second, third and fourth groups, the teeth were apicoectomized, submitted to cavity preparations and retrofilled with one of the following materiais: zinc free silver amalgam, a dentin bonding system plus composite resin, a glass ionomer cement ora compomer. In the fifth, sixth and seventh groups, the teeth were apicoectomized and capped on the bevelled root surface with one of the following materiais: a dentin bonding system plus composite resin, a glass ionomer cement or a compomer. Two specimens of each experimental group were evaluated for the marginal adaptation using scanning electron microscopy. The remaining 126 specimens were immersed in 2% methylene blue dye, stored for one week at 37ºC and the infiltration was evaluated with a stereomicroscope. The results showed that the glass ionomer cement presented the lowest values of marginal infiltration when used as retrofilling material, with a significant statistical difference when compared with the others tested materials. When used as apical capping, the glass ionomer cement and the compomer were equivalent and significantly better than the dentin bonding system plus composite resin. Using scanning electron microscopy, all the materials showed some slight adjustment problem. ln the retrofilling, the smallest marginal gaps were observed with the compomer and the dentin bonding system plus composite resin, while the largest were observed with the glass ionomer cement and zinc free silver amalgam. ln the apical capping, the smallest marginal gaps were observed with the compomer and the dentin bonding system plus composite resin and ...

Editoração eletrônica: novos comportamentos editoriais e estéticos

This dissertation shows a new tool in the process of producing specialized printed media: desktop publishing. Because it is an important tool to this communication media, the visualization of its evolutionary journey began in the pre-history of informative vehicle, advancing to the informatics society. And it was just in this last social stage that desktop publishing legitimized its function, resulting in impacts on the production of these media and conditioned new styles. At the presentation of this new post-industrial society, a change of work and leisure sphere was verified, whose fusion is present and in this interaction, desktop publishing arose at home, in the little bureaus. In this journey, desktop publishing became an object of reflection because of its conditioning aspects that fostered moments of observation in relation to a possible threat to creativity, thanks to its facilities and clichés. On the other hand, different positive aspects of desktop we also shown, at the same time, its conditioning aspects resulting into a restudy of its execution in different printed media, showing its effects and sharing points of view. So, new styles and a editorial way of production were seen too. Add to this aspect desktop publishing – in general meaning – the computerization of magazine articles – has been producing resignation of journalists, which is another important aspect in the presenting dissertation.

Desenvolvimento de uma planilha eletrônica em VBA para o dimensionamento didático de instalações de recalque de água

This study aims to develop a computer program based on VBA programming language, using Microsoft Excel, for designing pumping systems of water. The program allows the user to determine the economical diameter, using the equation of Bresse, for a given installation, since the geometric elevation, the material of the tube, the accessories along the line and the volumetric flow are known. In addition, the program estimates the total annual cost of the installation for three different diameters, in order to compare which diameter is more advantageous from an economical perspective. The program interface is designed to be simple and intuitive with the intention of being didactic and offering to engineering students an advantageous tool to analyze this type of project. Microsoft Excel was chosen for this work because is present in virtually all personal computer, and is an indispensable tool for educational purposes

Estudo histológico e comparativo das papilas linguais dos cervídeos Mazama americana e Mazama gouzoubira por microscopia de luz e eletrônica de varredura

O tipo de alimentação depende do ambiente em que o animal se encontra, sendo este um fator responsável pela alteração da morfologia, como a estratificação e o nível de queratinização da língua, e a funcionalidade da mesma. Dentre as estruturas morfológicas funcionais da língua, as papilas vêm merecendo destaque devido a sua estreita relação com a dieta. Foram utilizadas duas espécies de cervídeos: cinco Mazama gouazoubira e duas Mazama americana, dividindo-se a língua em três partes: ápice, corpo e raiz. Analisou comparativamente a língua de duas espécies por meio de microscopia de luz e eletrônica de varredura. As papilas filiforme, fungiforme e valada apresentaram na língua das duas espécies estudadas, e com a mesma distribuição, mudando apenas a quantidade e formato de papilas filiformes no ápice lingual e a quantidade e disposição das papilas valadas na raiz da língua, fator este que pode ser ligado à dieta dos animais. . Além disto, sua distribuição é semelhante à de outras espécies de herbívoros.
