Obtenção e caracterização óptica e elétrica de 'La''Ta'O IND.4' e LiTaO Ind.3 puros e dopados com Eu POT.3+

Eletronicalceramics are used in many applications such as: multilayer capacitor, transducer, pyroelectric sensors and electrooptic devices. In recent years there has been a growing demand for eletronicalceramics with better performance and functionality. This demand has accelerated the development of synthesis techniques to produce powders with well-defined particle size, shape and crystallinity. The eletronicalceramics in the form of bulk are determined by their performance characteristics of the powders used and the preparation process. So, physical and chemical properties of powders, such as chemical control of stoichiometry, purity, homogeneity, particle size and shape should be observed when choosing the methods of synthesis. Among the techniques used so far, the polymeric precursor method, also known as Pechini, has been considered ideal for the preparation of nanosized powders. Thus, this research project aims to use the polymeric precursor method to prepare powders of lithium tantalate and lanthanum tantalate, with good chemical stability. In this aspect is proposed to investigate the effects of variation of the concentration of europium about the properties of tantalate because doping with Eu3 + indicates that they may occupy different sites in the crystal structure, as in the case of LiTaO3. Effects of things like occupation sites, stability of phases and formation temperature have been previously investigated by the group, which motivated the formulation of this project. Our proposal aims to introduce the Eu3 + LaTaO4 and LiTaO3 and study the structural and optical properties of the powders obtained by Pechini method, as well as correlate these studies with the electrical properties of the material, mainly the Ironelectricty Hysteresis.

Explorando potencialidades para a criação de rede de apoio social a mulheres lusófonas que vivem com câncer de mama em Toronto, Canadá

Introduction: Health indicators tend to be altered due to the participation of people in social networks. Objective: To find out ideas of individuals belonging to Portuguese speaking communities in Toronto, Canada, about the possibility of creating a social support network for women experiencing breast cancer. Method: Nineteen participants of the present ethnographic and critical study answered to questions, providing their opinions regarding to the social support network and its positive and negative aspects. Also, the participants suggested other possible individuals who could participate and help in the creation of such network. Discussions were transcribed, analysed and coded using qualitative software called Atlas ti 6.0. Results: The main components for the creation of the social support network were: the demystification of breast cancer and its prevention, emphasis in health education, dissemination of the need of volunteers and a direct social support to those women. The positive aspects were the participation of oldest women as social leaders and the utilization of schools and religious institutions for publicity. Negative aspects that were perceived as barriers are: the belief that breast cancer is a disease lived by women, the lack of knowledge about its cure and rehabilitation, as well as a collective sensitiveness to it. Also, about the participation of community leaders, the suggestions were: diplomats, priests and pastors, schools directors and communication entrepreneurs. Conclusion: The creation of the social support network should consider the cultural sensitiveness and the inner diversity of the consulted Portuguese speaking communities. Due to the insufficient number of Angolan participants to sustain a major analysis, a special recommendation was that Angolan social leaders and professionals should be invited to design the structure of such network according to their specific cultural traits.

Tratamento de manipueira de fecularia em biodigestor anaerobio para disposição em corpo receptor, rede pública ou uso em fertirrigação

O objetivo do presente trabalho foi avaliar a eficiência do tratamento da manipueira de extração de fécula de mandioca, em separado da água de lavagem das raízes, através de biodigestores anaeróbicos de fluxo ascendente, com separação das fases, sem controle de temperatura ou adição de produtos químicos e, avaliar sua adequabilidade, através de suas características físicas e químicas para lançamento em corpo receptor, sistema público coletor de esgotos ou, aplicação em processod e fertirrigação. Depois dos reatores estabilizados, foram realizados ensaios variando a vazão de alimentação com 8,0; 12,0 e 16,0 L/d, correspondentes a um tempo de retenção hidráulica de 8,17; 5,44 e 4,08 dias, respectivamente. Os melhores resultados para redução da carga orgânica foram obtidos com os tempos de retenção hidráulica (TRH) de 8,17 e 5,44 dias com eficiências médias de 89,8% e 80,9%, respectivamente. As características físicas e químicas dos efluentes tratados foram comparadas com os valores estabelecidos na legislação estadual, federal e, com os parâmetros utilizados pelo orgão ambiental fiscalizador. Os resultados obtidos mostraram que o efluente tratado atende parcialmente aos requisitos legais para o lançamento em corpos receptores, devido ao teor elevado de nitrogênio amoniacal. Por outro lado, foram atendidos integralmente os requisitos legais para o lançamento na rede pública coletora de esgotos. O efluente tratado não atendeu às recomendações requeridas pelo orgão ambiental fiscalizador para a sua disposição através do processo de fertirrigação devido aos teores elevados de ferro (Fe) e de fluoretos (F). Considerando os resultados obtidos, concluímos que, devido à simplicidade do sistema utilizado, com a implantação de melhorias como um pós-tratamento, poderiam ser atingidos os parâmetros que atenderiam integralmente a legislação.

Adaptação da produção aos objetivos de competitividade e produtividade: a pesquisa-ação em uma manufatureira de cutelaria inserida em rede

One of the oldest segments in operations management, whose models are always subject to development efforts, for academics and productive organizations, is the management of production and work organization. Proposals for strategic management principles that seek to bring production to streamline processes reduce costs and add value, identifying problems with material flow and information while reducing the response time. This is realized through the pursuit of the best actions to achieve goals and targets established in a successful Planning and Production Control. This article aims to identify and implement actions that increase the speed of supply of goods produced in a enterprise cutlery; positively influencing the perception of customers. Such attitudes benefit all actors involved in the network, a fact which is expressed in the production chain. To lay the foundations of research and validate the data obtained, it was a study drawing on action research methodology. The goods produced are sold, mainly to wholesalers. Was proved seven aspects to improve and enhance the competitiveness of the organization, among them the complete design of the network, integrating upstream and downstream actors.

Projeto Político Pedagógico (PPP): o resgate de sua implantação na rede municipal de ensino de Londrina

The aim of this paper is to present a historical review of the implementation process of the political pedagogical project (PPP) of Londrina (PR). The study used interviews with some agents who participated in the construction of the PPP (teachers, school, supervisors and employees of the Regional Education Center) and investigated the absorption of proposals from the base (school) for the offices of political power. The results showed that although the democratic discourse has always been present in official documents the construction of the PPP had discrete popular participation and projects, as a rule, incorporated the bureaucratic forms issued by official powers.
