1. Aportes teóricos a la investigación del campo periodístico. Sentidos y significados desde el Campo Intelectual Creador
Resumo O habitus acadêmico presente na estrutura do campo da pesquisa jornalística na Espanha desenvolve uma tendência à perda de trabalhos teóricos conceituais. Desenvolvendo as bases da pesquisa qualitativa utilizando técnicas e procedimentos do método de comparação constante, o texto visa integrar, em termos descritivos e preditivos, o constructo

2. Dynamic Arrays Based on Magnetically Controlled Particles: Synthesis and Application
Growth mechanisms of dynamic granular arrays based on magnetically controlled particles are presented. Method of the external rotating magnetic field (ERMF), based on a dipole interaction of magnetic spherical Fe3O4 particles in highly ordered volume arrays is proposed and a design for its practical implementation is developed. The magnetic assembly can resu

3. Chilean sport sciences scientific production indexed in the Web of Science (1981-2016)
Abstract AIM To carry out a bibliometric analysis of the Chilean Sport Sciences scientific production indexed in the Web of Science until 2016. METHODS Chilean Sport Sciences articles and reviews included in the Web of Science Core Collection indexes until 2016 were analyzed. Data was collected and filtered in Endnote X6 programme and then exported to Exce

4. As famílias de crianças e adolescentes em contextos de violação de direitos
The goal of this study was to analyze the families of children and adolescents at risk with history of violation of rights. The conceptions of authors based in the Critical Theory (Azevedo, 2009; Bruschini, 2009) were used as support, in order to understand the category family. To define risk, in relation to children and adolescents, the authors Lescher et a

5. Solidariedade e organização social : a luta do "Movimento de Ilhéus" pela gestão social do território no arquipélago em Porto Alegre
This thesis explores a field of study known as Social Management - by definition a public administration exerted by different social actors in public decision-making. The general objective of this thesis is to understand the process of construction of social organization in a territory from the analysis of the mediations that help or hinder the establishment

6. Líquidos nemáticos e relatividade geral
In the mean 80´s, it was proposed that the rheologic properties of liquidcrystal could be obtained through affine transformation, in which the interaction potential of aspheric molecule is deformed to assume the ellipsoidal shape of potential liquid crystal´smolecular interaction. When this procedure is done point to point, the usuals derivatives donot get

7. Efeitos cosmológicos induzidos por campos quantizados / Cosmological effects induced by quantized fields
The present dissertation reviews the coupling of a scalar non-interacting quantum field with the metric of a FLRW(Friedmann-Lemaítre-Robertson-Walker) spacetime, proposed in a work by C. Dappiaggi, K. Fredenhagen and N. Pinamonti. We present methods for the quantization of a real Klein-Gordon field in globally hyperbolic spacetimes and discuss procedures fo

8. Formação de sólitons em condensados de Bose-Einstein e em meios ópticos / Formation of solitons in Bose-Einstein condensates and in photorefractive media
Different kinds of solitons have already been observed in various nonlinear optical media, and their behavior has been explained in the frameworks of such mathematical models as the nonlinear Schrödinger and generalized nonlinear Shrödinger equations for different dimensions and geometries. However, there are situations when many solitons are generated so

9. LRS Bianchi type -V cosmology with heat flow in scalar: tensor theory
In this paper we present a spatially homogeneous locally rotationally symmetric (LRS) Bianchi type -V perfect fluid model with heat conduction in scalar tensor theory proposed by Saez and Ballester. The field equations are solved with and without heat conduction by using a law of variation for the mean Hubble parameter, which is related to the average scale

10. Efeitos de desordem na transição metal-isolante de Mott / Efects of disorder on the Mott metal-insulator transition
We determine the phase diagram of the disordered Hubbard Model as a function of temperature and interaction strength by means of the Statistical Dynamical Mean Field Theory. The metallic and insulating spinodal lines are traced for weak and moderate disorder using Quantum Monte Carlo as the impurity solver. We find that disorder pushes the spinodal lines to

11. Intenção de escolha de ensino superior privado à luz da Teoria do Comportamento Planejado.
The aim of the study was to analyze the behavior purchase of the high school students by Planed Behavior Theory (PBT) and their relationship with marketing actions in social choice study in a private college. When behavior consumer investigation is performed, the researchers had highlighted the attitude evaluation by PBT. This kind of theory was developed to

12. Extended Bell´s Be-ables and Atenuattion × Amplification Competition. / Extensão dos Be-ables de Bell e Competição Atenuação x Amplificação
In the first part of this work we employ the Itô stochastic equation to extend Bells be-able interpretation of quantum mechanics to encompass dissipation, decoherence and quantum-to-classical transition through quantum trajectories. For a particular choice of the source of stochasticity, the one leading to a dissipative Lindblad type correction to the Hamil
