Diferentes arranjos institucionais resultam em diferentes incentivos para a realização de trocas econômicas. Com efeito, estruturas regulatórias implementadas em determinado contexto histórico-econômico podem resultar em consequências diversas daquelas originariamente pretendidas, impondo ao regulador a necessidade de constante monitoramento e de intervenções com vistas a diagnosticar e corrigir ou minimizar possíveis distorções nas relações entre os atores envolvidos. Assim, esta dissertação tem por objetivo analisar o funcionamento do Consórcio do Seguro DPVAT como mecanismo de conexão entre seus diversos stakeholders. Pretende-se analisar a existência de conflitos de interesses derivados das diversas relações entre as partes interligadas – geradas pelo arranjo institucional firmado para a gestão dos recursos arrecadados com os prêmios pagos pelos proprietários de veículo automotor para o Seguro de Danos Pessoais Causados por Veículos Automotores de Via Terrestre, ou por sua carga, a Pessoas Transportadas ou Não (DPVAT) – que possam suscitar intervenção regulatória no sentido de evitá-los, ou, ao menos, mitigá-los. A pesquisa é conduzida a partir da identificação dos comportamentos esperados de agentes econômicos autointeressados, tendo por referência os pressupostos da Nova Economia Institucional sob a perspectiva da Teoria da Agência, e do exame das principais mudanças legislativas havidas na estrutura do seguro obrigatório de trânsito no Brasil nos últimos 50 anos. Na sequência, com base em elementos teóricos e empíricos, foram identificados e analisados três conflitos de agência entre os stakeholders do Consórcio DPVAT: o primeiro seria aquele havido entre a entidade gestora do Consórcio DPVAT (agente) e as sociedades seguradoras consorciadas (principal); o segundo conflito observado refere-se à relação mantida entre a entidade gestora do Consórcio DPVAT (agente) e o órgão regulador (principal); e, por fim, o conflito de agência existente entre a seguradora que administra o referido consórcio (agente) e os proprietários de veículo automotor (principal).

Situado num edifício do séc. XIX, o Centro Cívico e Cultural de Santa Clara – Universo de Memórias João Carlos Abreu foi adquirido pelo Governo Regional em 2002, para acolher todos os bens doados à Região Autónoma da Madeira, por João Carlos Nunes Abreu. Este Centro Cívico e Cultural é responsável pela manutenção e exposição ao público do espólio doado, estando também vocacionado para acolher e desenvolver acções de carácter cultural. Dispõe de um jardim, de uma Casa de Chá e de um Auditório. Encenado como um “caleidoscópio”, o “Universo de Memórias João Carlos Abreu” é um repositório de memórias construídas ao longo da sua vida de jornalista, viajante, poeta, escritor, político, actor e artista, com passagem por diversos países. Institucionalmente falando, este é um espaço relativamente recente, criado “de raíz” para acolher, expor e divulgar colecções pertencentes a uma só pessoa. Desta forma, iniciaremos este estudo com uma abordagem aos factores que constituem a realidade da Instituição – política de funcionamento, colecções albergadas, aspectos relevantes da vida do doador e espaço físico. Na segunda parte, o nosso trabalho irá recair sobre a componente virtual da Instituição sob o ponto de vista da utilização das novas tecnologias. Abordaremos,sucintamente, o ciberespaço e o mundo da Internet e culminaremos o estudo com a elaboração do site oficial do Centro Cívico e Cultural de Santa Clara – Universo de Memórias João Carlos Abreu que permitirá potenciar o acesso à Instituição de forma mais ampla, fazendo com que esta ultrapasse as suas próprias fronteiras físicas. Pretende-se que este site seja, acima de tudo, dinâmico de maneira a envolver o visitante, fidelizando-o e consequentemente fazendo com que este queira passar da virtualidade à realidade visitando o espaço físico.

O presente trabalho é o estudo da poesia de Carlos Drummond de Andrade (1902-1987) através de uma análise da sua arte poética publicada entre Alguma Poesia (1930) e Farewell (1999). De um projecto de escrita que implicaria inevitavelmente as relações entre a poesia e a realidade, explora-se o conceito metapoético que pode insinuar a privação de contacto entre a poesia e o real empírico. Num primeiro momento, após uma sucinta referência à tradição da poesia sobre a poesia, chega-se à noção de um preconceito contra a metapoesia no século XX e define-se um ponto de partida para a análise propriamente dita da poética drummondiana. Num segundo capitulo, as noções de poeta, poema ou verso, ou melhor, de poesia, são estudadas nas suas particularidades, concomitantemente com a estruturação da arte poética de Drummond. Por fim, a auto-reflexividade é analisada na relação que estabelece entre a metapoesia e a ekphrasis. É neste movimento de auto-reflexão e transformação que assiste a capacidade drummondiana de revelar através da metapoesia não só a sua posição perante as palavras, mas também perante as coisas.

This paper proposes a reflection on the body between/bodies, especially in contemporary dance, in their path that starts from the choreographic construction, permeating the body of the choreographer, the dancer s body and when fulfills themselves as artistic expression, the body of the spectator. Initially discusses the body in dance as a body/space for convergence, connectedness and continuity, from the thought of the Greek philosopher Epicurus of Samos, in dialogue with the thought of Maurice Merleau-Ponty, Gilles Deleuze and José Gil. Reflect about the creation of this body/space in the relationship choreographer/dancer using as connecting thread the experiences of the author in his artistic path. Finally describes the process of creating the scenic experiment (h)áporos, which constitutes the practice scene of this dissertation, having as main objective the creation of spaces of convergence and interaction between a proponent and an affluent body that, in this move, transforms itself and the space that now cohabits / is

Synthetic inorganic pigments are the most widely used in ceramic applications because they have excellent chemical and thermal stability and also, in general, a lower toxicity to man and to the environment. In the present work, the ceramic black pigment CoFe2O4 was synthesized by the polymerization Complex method (MPC) in order to form a material with good chemical homogeneity. Aiming to optimize the process of getting the pigment through the MPC was used a fractional factorial design 2(5-2), with resolution III. The factors studied in mathematical models were: citric acid concentration, the pyrolysis time, temperature, time and rate of calcination. The response surfaces using the software statistica 7.0. The powders were characterized by thermal analysis (TG/DSC), x-ray diffraction (XRD), scanning electron microscopy (SEM) and spectroscopy in the UV-visible. Based on the results, there was the formation of phase cobalt ferrite (CoFe2O4) with spinel structure. The color of the pigments obtained showed dark shades, from black to gray. The model chosen was appropriate since proved to be adjusted and predictive. Planning also showed that all factors were significant, with a confidence level of 95%

Magnetic ceramics have been widely investigated, especially with respect to intrinsic and extrinsic characteristics of these materials. Among the magnetic ceramic materials of technological interest, there are the ferrites. On the other hand, the thermal treatment of ceramic materials by microwave energy has offered various advantages such as: optimization of production processes, high heat control, low consumption of time and energy among others. In this work were synthesized powders of Ni-Zn ferrite with compositions Ni1- xZnxFe2O4 (0.25 ≤ x ≤ 0.75 mols) by the polymeric precursor route in two heat treatment conditions, conventional oven and microwave energy at 500, 650, 800 and 950°C and its structural, and morphological imaging. The materials were characterized by thermal analysis (TG/ DSC), X-ray diffraction (XRD), absorption spectroscopy in the infrared (FTIR), scanning electron microscopy (SEM), X-ray spectroscopy and energy dispersive (EDS) and vibrating sample magnetometry (VSM). The results of X-ray diffraction confirmed the formation of ferrite with spinel-type cubic structure. The extrinsic characteristics of the powders obtained by microwave calcination and influence significantly the magnetic behavior of ferrites, showing particles ferrimagnéticas characterized as soft magnetic materials (soft), is of great technological interest. The results obtained led the potential application of microwave energy for calcining powders of Ni-Zn ferrite

This work aims at obtaining nanoparticles of iron oxide, the magnetite one (Fe3O4), via synthesis by thermal decomposition through polyol. Thus, two routes were evaluated: a simple decomposition route assisted by reflux and a hydrothermal route both without synthetic air atmosphere using a synthesis temperature of 260ºC. In this work observed the influence of the observe of surfactants which are generally applied in the synthesis of iron oxide nanoparticles decreasing cluster areas. Further, was observed pure magnetite phase without secondary phases generally found in the iron oxide synthesis, a better control of crystallite size, morphology, crystal structure and magnetic behavior. Finally, the introduction of hydroxyl groups on the nanoparticles surface was analyzed besides its employment in the polymer production with OH radicals. The obtained materials were characterized by XRD, DLS, VSM, TEM, TG and DSC analyses. The results for the magnetite obtainment with a particle size greater than 5 nm and smaller than 11 nm, well defined morphology and good magnetic properties with superparamagnetic behavior. The reflux synthesis was more efficient in the deposition of the hydroxyl groups on the nanoparticles surface

In recent decades have seen a sharp growth in the study area of nanoscience and nanotechnology and is included in this area, the study of nanocomposites with self-cleaning properties. Since titanium dioxide (TiO2) has high photocatalytic activity and also antimicrobial, self-cleaning surfaces in your application has been explored. In this study a comparison was made between two synthesis routes to obtain TiO2 nanoparticles by hydrothermal method assisted by microwave. And after analysis of XRD and SEM was considered the best material for use in nanocomposites. It was deposited nanocomposite film of poly (dimethyl siloxane) (PDMS) with 0.5, 1, 1.5 and 2% by weight of nanoparticles of titanium dioxide (TiO2) by the spraying method. The nanocomposite was diluted with hexane and the suspension was deposited onto glass substrate, followed by curing in an oven with forced air circulation. The photocatalytic activity of the nanocomposite impregnated with methylene blue was evaluated by UV- vis spectroscopy from the intensity variation of absorption main peak at 660nm with time of exposure to the UV chamber. Changes in the contact angle and microhardness were analyzed before and after UV aging test. The effect of ultraviolet radiation on the chemical structure of the PDMS matrix was evaluated by spectrophotometry Fourier transform infrared (FTIR).The results indicated that the addition of TiO2 nanoparticles in the coating PDMS gave high photocatalytic activity in the decomposition of methylene blue, an important characteristic for the development of self-cleaning coatings
