Por mais que a informatização esteja avançada (interligação por meio da rede internet de computadores entre os órgãos e entidades públicas pelo Estado), máquina alguma substituirá os dramas do homem contemporâneo, principalmente aqueles que sempre estiveram alijados da cidadania. O presente estudo traz à baila as reflexões e discussões acadêmicas desenvolvidas ao longo das mais de 700 horas/aulas do curso de mestrado em Poder Judiciário, turma 2010. Longe de ser uma unanimidade o Poder Judiciário é um poder do Estado que representa antes de tudo a capacidade e a prerrogativa de julgar, de acordo com as regras constitucionais e das leis criadas pelo Poder Legislativo em determinado país. É um dos mais sólidos pilares nas democracias e um perigoso algoz nos regimes absolutos. Apesar desta importância e de no Brasil ser um poder sólido que já demonstrou sua importância para a garantia da solidificação da democracia, são poucos os estudos sobre o Judiciário, poucos e iniciais são as pesquisas sérias sobre este poder de suma importância para a sociedade, para economia e para as instituições. Como, também, não é espanto quando vemos que fato repetitivo que a maior insatisfação ou reclamação da sociedade reside na morosidade das soluções judiciais traduzida pela alta taxa de litigiosidade da justiça brasileira. O Poder Judiciário é objeto de estudos sistemáticos, contínuos e avançados em diversos países que já demonstraram a importância de se conhecer bem as suas propostas, os resultados das suas atividades, funções e os seus gastos, pois, o seu “negócio”é a resolução dos conflitos da sociedade de forma a contribuir com a pacificação da mesma através de uma ordem jurídica justa. Os estudos realizados nos Estados Unidos, Alemanha e Espanha, como exemplo, demonstram que conhecer bem o judiciário é o primeiro passo para melhor gerenciá-lo. Assim, deve-se menção e reconhecimento no investimento realizado pela Fundação Getúlio Vargas em promover com destaque o presente Mestrado em Poder Judiciário. A FGV é uma das poucas instituições privadas que tem como um dos seus objetivos o preparo pessoal, extrapolando as fronteiras do ensino com avanços significativos nas áreas da pesquisa e da informação. No mesmo caminho da qualificação profissional de seus magistrados e servidores e na vanguarda da gestão judiciária, o Tribunal de Justiça do Distrito Federal e dos Territórios, investiu e acreditou na proposta de estudos e pesquisas do presente mestrado, merecendo, significativamente, os elogios e agradecimentos pela visão de futuro e investimento realizado no conhecimento que é sempre importante e necessário. A dissertação em comento representa primeiramente uma visão contraposta ao modelo de política pública encampada pelo Conselho Nacional de Justiça, através da Resolução 125 de 29 de novembro de 2010, cujo objeto é o tratamento adequado dos conflitos de interesse no âmbito do Poder Judiciário, representando, assim, interesse especial de pesquisa científica por se tratar de uma política nacional judiciária a ser adotada, obrigatoriamente, por todos os Tribunais de Justiça do país. Além deste aspecto supra referido, reside, também, o fato do ineditismo deste estudo e pesquisa, especificamente, porque essa política pública judiciária aborda aspectos e variáveis novas no tratamento das atividades e das funções próprias do Poder Judiciário quando propõem, como exemplo, o tratamento dos conflitos considerados pré processuais. Outro aspecto importante merecedor de atenção no estudo reflete-se na discussão do modelo de política pública que, em premissa vênia, deveria ser tratado em caráter geral republicando do Estado e não particularizado em um dos seus entes, mesmo que pareça ser, constitucionalmente, pressuposto da alçada do Poder Judiciário tratar exclusivamente do problema da altíssima litigiosidade e do baixo resultado de resposta à demanda posta para seu controle. Este estudo, tem como objetivo demonstrar que a resolução 125/2010 do CNJ é insuficiente para resolver os problemas de congestionamento e morosidade da Justiça brasileira, como preconizada, isso porque, o modelo que se propõe para combater o problema da morosidade é restrito e está “contaminado” pela idéia do monopólio da jurisdição ou por uma espécie similar que traz para o âmbito do judiciário uma nova atividade de trabalho, a qual é relacionada com a solução do conflito pré-processual a qual deveria fazer parte de uma política pública geral não restrita a um poder republicano. A correspondência dos argumentos com a materialização utilizada para o problema será comprovada nas linhas que se seguem, pois, assuntos com grande abrangência como as soluções judiciais devem, preferencialmente, adotar mecanismos públicos de caráter geral para uma boa solução. Nesse sentido, o trabalho demonstrará que as tentativas recorrentes em superar o problema da alta demanda judicial está restrita a modelos insuficientes abrangidos por um monopólio que não deveria ser aplicado para solucionar problemas pré processuais no âmbito do Poder Judiciário. Constitui, pois, um contraponto à idéia de efetividade na redução da demanda judicial tradicional 1 como prevista pela política pública judiciária frente ao monopólio da jurisdição, ou seja, frente à reserva que detém o Judiciário na promoção e gestão de uma nova atividade – o tratamento dos conflitos de interesse pré-processual por meio dos instrumentos de autocomposição, notadamente as conciliações e mediações. Apresentam-se, igualmente, neste trabalho proposições legislativas que dão o suporte material às idéias apresentadas, caracterizando a comprovação de viabilidade entre a apresentação do problema científico, as justificativas para o enfrentamento do problema e uma solução para o mesmo, como vista a modernizar uma política pública. Importante reafirmar que o escopo do presente trabalho não reside na observação própria dos modelos e técnicas de resolução de conflitos, notadamente as conciliações e mediações, incentivadas pelo CNJ, ou nos modelos arbitragem. Ao contrário, espera-se que todas as tentativas que possam melhorar e modernizar os atuais serviços judiciais no Brasil sejam válidas, eficazes e são muito bem vindas, pois, é uma tentativa positiva para melhorar o atual cenário em que se encontra o Poder Judiciário quando é confrontado em seu acesso à justiça, rapidez, confiabilidade e segurança nos seus julgamentos.

This study shows a possibility of using municipal sewage sludge after thermal treatment in the production of a filtering material to water treatment. Due to the fast urbanization and implementation of high standards for effluent in many countries in recent years, the sewage sludge is being produced in an ever increasing amount. Therefore, the use of sludge is a suitable solution for the expected large quantity of sludge. Dehydration of sludge was performed by controlled heating at temperatures of 1100 degrees C, 850 degrees C, 650 degrees C, 350 degrees C for 3 hours. After thermal treatment the sludge was characterized by X-ray fluorescence, TG/DTG/DTA, residue solubilization and residue lixiviation tests. The aim of the present work was to observe, thought the characterization techniques, if the treated sewage sludge is or not adequate to be used as filter material to water treatment. It will be verified which treatment temperature of the sludge offer possibility to its use in water treatment without carrying pollutants in concentrations out of the standards.

In the globalized world modern telecommunications have assumed key role within the company, causing a large increase in demand for the wireless technology of communication, which has been happening in recent years have greatly increased the number of applications using this technology. Due to this demand, new materials are developed to enable new control mechanisms and propagation of electromagnetic waves. The research to develop new technologies for wireless communication presents a multidisciplinary study that covers from the new geometries for passive antennas, active up to the development of materials for devices that improve the performance at the frequency range of operation. Recently, planar antennas have attracted interest due to their characteristics and advantages when compared with other types of antennas. In the area of mobile communications the need for antennas of this type has become increasingly used, due to intensive development, which needs to operate in multifrequency antennas and broadband. The microstrip antennas have narrow bandwidth due to the dielectric losses generated by irradiation. Another limitation is the degradation of the radiation pattern due to the generation of surface waves in the substrate. Some techniques have been developed to minimize this limitation of bandwidth, such as the study of type materials PBG - Photonic Band Gap, to form the dielectric material. This work has as main objective the development project of a slot resonator with multiple layers and use the type PBG substrate, which carried out the optimization from the numerical analysis and then designed the device initially proposed for the band electromagnetic spectrum between 3-9 GHz, which basically includes the band S to X. Was used as the dielectric material RT/Duroid 5870 and RT/Duroid 6010.LM where both are laminated ceramic-filled PTFE dielectric constants 2.33 and 10.2, respectively. Through an experimental investigation was conducted an analysis of the simulated versus measured by observing the behavior of the radiation characteristics from the height variation of the dielectric multilayer substrates. We also used the LTT method resonators structures rectangular slot with multiple layers of material photonic PBG in order to obtain the resonance frequency and the entire theory involving the electromagnetic parameters of the structure under consideration. xviii The analysis developed in this work was performed using the method LTT - Transverse Transmission Line, in the field of Fourier transform that uses a component propagating in the y direction (transverse to the real direction of propagation z), thus treating the general equations of the fields electric and magnetic and function. The PBG theory is applied to obtain the relative permittivity of the polarizations for the sep photonic composite substrates material. The results are obtained with the commercial software Ansoft HFSS, used for accurate analysis of the electromagnetic behavior of the planar device under study through the Finite Element Method (FEM). Numerical computational results are presented in graphical form in two and three dimensions, playing in the parameters of return loss, frequency of radiation and radiation diagram, radiation efficiency and surface current for the device under study, and have as substrates, photonic materials and had been simulated in an appropriate computational tool. With respect to the planar device design study are presented in the simulated and measured results that show good agreement with measurements made. These results are mainly in the identification of resonance modes and determining the characteristics of the designed device, such as resonant frequency, return loss and radiation pattern

The search for alternative materials with lower density, reduction in heat transfer and propagation of noise associated with the ease of handling and application in concrete structures, represents an enormous challenge in the formulation and knowledge of the performance of self-compacting lightweight concrete, which has technology little known nationally, and appears on the international scene as an innovative material and alternative to conventional concrete. Based on these, this study set out to study self-compacting lightweight concrete made with two distinct grades of expanded clay associated with the addition of plasticizing/superplasticizers additives and mineral additions of metakaolin and bagasse ash of sugar cane. There is also an object of study, evaluation of pozzolanic activity of mineral admixtures and their influence on the durability characteristics of concrete. The rheological, physical, mechanical and microstructural analysis in this study served as basis in the classification of concretes autoadensáveis, targeting the national technical requirements for their classification in the category autoadensável and lightweight structural. The inclusion of mineral admixtures (metakaolin and bagasse ash of sugar cane), partial replacement of cement, pozzolanic activity and demonstrated maintenance of mechanical properties through the filler effect, a reduction of up to 76% of the nitrogen gas permeability in blend with 20% bagasse ash. All concretes had rheology (cohesion and consistency) suitable for self-adensability as well as strength and density inherent structural lightweight concrete without presenting phenomena of segregation and exudation

Actually, surveys have been developed for obtaining new materials and methodologies that aim to minimize environmental problems due to discharges of industrial effluents contaminated with heavy metals. The adsorption has been used as an alternative technology effectively, economically viable and potentially important for the reduction of metals, especially when using natural adsorbents such as certain types of clay. Chitosan, a polymer of natural origin, present in the shells of crustaceans and insects, has also been used for this purpose. Among the clays, vermiculite is distinguished by its good ion exchange capacity and in its expanded form enhances its properties by greatly increasing its specific surface. This study aimed to evaluate the functionality of the hybrid material obtained through the modification of expanded vermiculite with chitosan in the removal of lead ions (II) in aqueous solution. The material was characterized by infrared spectroscopy (IR) in order to evaluate the efficiency of modification of matrix, the vermiculite, the organic material, chitosan. The thermal stability of the material and the ratio clay / polymer was evaluated by thermogravimetry. To evaluate the surface of the material was used in scanning electron microscopy (SEM) and (BET). The BET analysis revealed a significant increase in surface area of vermiculite that after interaction with chitosan, was obtained a value of 21, 6156 m2 / g. Adsorption tests were performed according to the particle size, concentration and time. The results show that the capacity of removal of ions through the vermiculite was on average 88.4% for lead in concentrations ranging from 20-200 mg / L and 64.2% in the concentration range of 1000 mg / L. Regarding the particle size, there was an increase in adsorption with decreasing particle size. In fuction to the time of contact, was observed adsorption equilibrium in 60 minutes with adsorption capacity. The data of the isotherms were fitted to equation Freundlich. The kinetic study of adsorption showed that the pseudo second- order model best describes the adsorption adsorption, having been found following values K2=0,024 g. mg-1 min-1and Qmax=25,75 mg/g, value very close to the calculated Qe = 26.31 mg / g. From the results we can conclude that the material can be used in wastewater treatment systems as a source of metal ions adsorbent due to its high adsorption capacity

Neste trabalho, materiais compósitos de matriz poliéster reforçados por fibras curtas de sisal, por resíduo de madeira e por sistema híbrido sisal/resíduo de madeira, dispostos aleatoriamente foram produzidos, utilizando-se o menor nível possível de processamento tecnológico nas etapas produtivas, com vistas a se produzir um compósito tecnicamente viável a pequenos produtores. A matriz de poliéster utilizada foi a tereftálica pré-acelerada com naftenato de cobalto e curada a temperatura ambiente com peróxido de metil-etil-cetona (MEK) em diferentes proporções em relação à resina, 0,33%, 1,66%, 3,33% e 5,00% em volume, de forma a se avaliar a influência deste nas propriedades mecânicas. As fibras de sisal foram cortadas manualmente nos comprimentos de 5, 10 e 15mm e utilizadas da maneira como adquiridas, sem tratamento superficial. O resíduo de madeira utilizado foi o pó de lixadeira da madeira maçaranduba. Os compósitos foram fabricados por moldagem manual, sem pressão e a temperatura ambiente. Foram fabricados corpos de prova de matriz pura, compósitos reforçados por sisal, variando-se o comprimento das fibras, compósitos reforçados por pó de maçaranduba e compósitos de reforço híbrido, sisal/pó de madeira, em diferentes proporções entre os constituintes. As propriedades mecânicas foram avaliadas por ensaios de tração e impacto charpy e as superfícies de fratura geradas foram avaliadas por microscopia eletrônica de varredura de modo a se correlacionar os aspectos de fratura com as propriedades mecânicas. Foi determinada a massa específica de cada série de corpos de prova fabricada, bem como a fração volumétrica dos reforços nos compósitos. Os resultados demonstraram que com o aumento do comprimento da fibra de sisal a resistência à tração e ao impacto dos compósitos foi incrementada, alcançando, o compósito com fibras de sisal de 15 mm, o melhor desempenho mecânico dentre as séries testadas. Por outro lado, a heterogeneidade granulométrica do pó de maçaranduba teve efeito negativo sobre as propriedades mecânicas dos compósitos. Os compósitos híbridos sisal/pó de madeira com maior teor de fibras, alcançaram 80% do desempenho obtido para os compósitos de fibras de sisal.

Selecting a suitable place to install a new landfill is a hard work. Bauru is a Brazilian municipality where the local landfill currently in use has a life span that is almost over, and the selection of a new area for a future landfill is crucial and urgent. Here we use a geographic information system (GIS) approach to indicate possible suitable areas for installing the landfill. The considered criteria were: river network and the respective buffer zone, relief, urban areas and their respective buffer zone, existence of Areas for Environmental Protection (AEPs), occurrence of wells and their respective buffer zones, existence of airports and their buffer zones, wind direction, and the road network and its respective buffer zone. Due the facts that (1) Bauru has an urban area relatively large in relation to whole municipal area, (2) Bauru has two airports, and (3) this area encompasses parts of three AEPs, the model showed that there are few areas suitable and moderately suitable in Bauru, and the greater part of the municipality is unsuitable to install a new landfill. Due to this important finding reported here, the local policymakers should consider the suitable or even moderately suitable areas for analysis in situ or look for other creative solutions for destination of the solid waste. We highly encourage the use of GIS in studies that seek suitable areas for future landfills, having found that SIG was a tool that allowed fast and precise work and generated an outcome sufficiently clear of interpretation.Implications: Solid waste (SW) management is one of the main environmental concerns nowadays. Landfilling SW is still the main practice to disposal of such material. However, for many regions, suitable places for landfilling are getting scarce. This study proved this situation for a populous place in a southeastern Brazilian region. This study also showed how the decision makers should manage the problem in order to minimize the amount of SW generated and delivered for the landfill. Massive investment in education is a critical issue to reach the proposed aim.

UNATI (Open University of the Third Age), UNESP, Marília campus, has offered subsidies for the development of this work aimed at researching the existing relationships between information mediation processes and technological devices, especially computers, assuming that reading practices and textual construction in online environments could help the “third age” population to have access to these devices, thus promoting digital inclusion in this group. Mediation was presented as an interventionist action that, by introducing an intermediate element in the learning process, causes a rupture in the ways of living and personal digital inclusion processes hitherto experienced. In the context of a workshop, we found out that there is a physical relationship between subjects and technological supports and such a contact proved to be necessary, considering that handling a computer required knowledge of procedures, thus furthering a logic of use. It turned out to be necessary to develop actions that would enable the handling of a computer so as to bring about acceptance of these supports. Accordingly, activities were developed so as to articulate reminiscent processes, memories of older adults, the writing down of such memories and the creation of a blog to bring enhanced visibility to the content produced by older people. Such actions have shown that remembering, writing down and posting can reshape not only social relations but somehow significantly promote digital inclusion among older adults.
