1. MICROWAVE DEVICES USING HIGH DIELECTRIC CONSTANT FILMS / DISPOSITIVOS DE MICROONDAS UTILIZANDO FILMES DE ALTA CONSTANTE DIELÉTRICA
The growing demand for portable devices with more reduced size and weight has stimulated the search for materials with high dielectric constant and low losses in the microwave frequency range allowing circuit integration and miniaturization. In this work, a theoretical and experimental study of the use of high dielectric constant films in the fabrication of

2. Fiandeira de versos: o imaginário do tecer poético de Hilda Hilst
The lyric production of Hilda Hilst (1930 - 2004) is marked by the use of symbolic images that amplify endlessly the possibilities of reading her poems. In her knowledge about the world, the poet discovers the cosmos that surround the time which presents her views recast by the poetic reverie. The symbols used by Hilst are expressions of a soul that made the

4. Estudo da prevalência da posição vestíbulo-lingual do canal mandibular por meio da tomografia computadorizada helicoidal / Prevalency study of the vestibulo-lingual position from the mandibular canal by helical computerized tomography
The course of the mandibles canal is oblique with posterior-anterior direction, it comes close to the medial cortical alveolar bony, until reaching the mesial face of the first inferior molar, starting from this area, it approaches of the lateral cortical alveolar bony until reaching the forame mentual. Radiographically, the manbible´s canal comes, as a rad

5. Argumentos e metáforas conceituais para a taxa de variação
The aim of this investigation was to identify and to analyze arguments and metaphors used by a group of students of a masters degree course in Mathematical Education for the rate of change, to understand how they learn this topic. The option of working with those subjects relapsed in the fact that they are all teachers of Mathematics and they have already se

6. Derivada/reta tangente: imagem conceitual e definição conceitual
This is a diagnostic research. The objective of this research is to investigate elements of the concept image and concept definition related to the concept of derivative while interpreted geometrically. It is based on the David Tall and Shlomo Vinner theory about concept image and concept definition. The investigated persons are students of the Formation Cou

7. Dynamically stabilized pores in bilayer membranes.
Zhelev and Needham have recently created large, quasistable pores in artificial lipid bilayer vesicles. Initially created by electroporation, the pores remain open for up to several seconds before quickly snapping shut. This result is surprising, in light of the large line tension for holes in bilayer membranes and the rapid time scale for closure of large p
