Er3+-doped Y2O3 obtained by polymeric precursor: Synthesis, structure and upconversion emission properties

The relentless pursuit for materials containing rare earth ions with photoluminescent properties has led to several studies with applications in the development of new technologies. The main focus of this work is the preparation of Er3+-doped polycrystalline Y2O3 with photoluminescent properties using PEG as an organic precursor and heat-treated at different temperatures. The methodology used in this synthesis is highly attractive due to its high feasibility for improved technology and low cost for preparing materials. The behavior of the viscous resin has been evaluated and the final compounds exhibited the formation of a cubic polycrystalline phase, which is able to support variations in Er3+ doping concentrations up to 10 mol%, without significant changes in the polycrystalline parameters. The values of the nanocrystallite size calculated by Scherrer's equation showed direct dependence on the heat-treatment temperature as well as the Er3+ concentration. Intense emission in the visible region under excitation at 980 nm was attributed to an upconversion phenomenon assigned to the intraconfigurational f-f transitions of Er3+ ions. The upconversion mechanism was investigated and it was demonstrated that the higher intense emission in the red region in comparison to the emission in the green region is related to the crystallite size. The studies about the intensity showed the dependence of upconversion emission of power source, indicating that two-photon are responsible for the green and red photoluminescence. These polycrystalline materials exhibit properties that make them promising for use in solar energy systems, C-telecom band or solid-state laser devices. (C) 2014 Elsevier B.V. All rights reserved.

Performance and emissions of a gas turbine engine using ox tallow ethyl-ester blended with kerosene

The performance and emissions behavior of a Rover 1S/60 turboshaft engine when operated with several blends of aviation kerosene and ox tallow ethyl-ester are shown in this article. The tests were performed with a compressor shaft coupled to an hydraulic dynamometer where data of power and mass fuel flow were collected to determine the brake specific fuel consumption. A flue gas analyzer was positioned at the exhaust duct to collect oxygen, carbon dioxide, carbon monoxide and nitrous oxides. An increase in the specific fuel consumption was observed due to the lesser lower heating value of the most oxygenated blends. However, reductions of CO, CO2 and NO (x) have been observed and no-significant ill effects have occurred in the turbine operation.

A Time-domain Harmonic Power-Flow Analysis in Electrical Energy Distribution Networks, Using Norton Models for Non-linear Loading

The purpose of this paper is to present the application of a three-phase harmonic propagation analysis time-domain tool, using the Norton model to approach the modeling of non-linear loads, making the harmonics currents flow more appropriate to the operation analysis and to the influence of mitigation elements analysis. This software makes it possible to obtain results closer to the real distribution network, considering voltages unbalances, currents imbalances and the application of mitigation elements for harmonic distortions. In this scenario, a real case study with network data and equipments connected to the network will be presented, as well as the modeling of non-linear loads based on real data obtained from some PCCs (Points of Common Coupling) of interests for a distribution company.

Tecnologias de gênero, masculinidades e apriosionamentos na execução penal

The study articulates the relations of power / knowledge in the production of crime and operationalization of the law, the subtle way in which technologies of gender naturalize actions and reactions in relationships, partnerships and daily struggles between staff and prisoners and the processes of subjectivity in contemporaneity . This study has as epistemological matrix the genealogy proposed by Michel Foucault, who has allowed diverse pathways as document reviews, semi-structured interviews, performance groups and courses. The interweaving of the forces and discourses has engendered the impact of technologies on gender, especially masculinity, in the present relations between staff and prisoners. The impact of this relationship puts on display the modulations of subjectivity in a continuum of oscillation between normalizing and singularizing modes of subjectification.

The role of the state in health public policies: an overview of the debate on the concept of State and the Brazilian case

This article is the result of a narrative literature review. The objective is to show the development of an overview on the ideological debate on the design of state health policies. We argue that the role of the state in the development of health policy, even under the pressure of the global market, may create alternatives to promote and drive economic and social development, meaning they are not subject to economic constraints imposed by the liberal ideal of market. Here is a part of a theoretical discussion about the construction and presence of the State in Latin America, particularly in Brazil. We take the approaches of the Marxist tradition and liberal to the issue as reference. This discussion allows us to understand the historical role of the state in the maintenance of social policies, specifically health, is an alternative to public control eases the intense capital mobility promoted by economic globalization. In this sense, the theme makes the Brazilian health an important issue of social sciences, why is the historicity of the construction of the Brazilian health system, as a public policy that can mirror the actual reconstruction of the institutional framework of the Brazilian state with the establishment instances of negotiation between the various spheres of power that strengthen the state in this process of democratization of Brazilian society.

Instituições, confinamento e relações de poder: questões metodológicas no pensamento de Michel Foucault

O artigo trata de uma discussão sobre a análise de instituições a partir do pensamento de Michel Foucault. Um dos objetivos é interrogar a afirmação de que Foucault definiu os mecanismos disciplinares como restritos ao confinamento em algumas instituições. Visa-se ressaltar que as relações de poder não eram propriedade de uma instituição ou apenas restritas ao Estado. Busca-se pensar como as tecnologias biopolíticas também extrapolam o âmbito estatal e operam governos das condutas por meio de articulações e composições e não ficam apenas fixadas em uma entidade de maneira naturalizada. Outro ponto tratado é o questionamento realizado por Foucault da visão de poder apenas como repressão e massificação operada pelas instituições. Finaliza-se, apontando a preocupação central de Foucault, qual seja, a análise das práticas, e não apenas das instituições.
