Fontes para o estudo do Neopentecostalismo brasileiro: O caso da Igreja Universal do Reino de Deus

Denomina-se Neopentecostalismo o movimento religioso que se configurou no Brasil, na década de 1970, como uma ramificação do chamado Pentecostalismo clássico, surgido nos Estados Unidos da América, no início do século XX. Para a pesquisa do tema proposto, adotam-se como principais fontes as literaturas neopentecostais, matérias jornalísticas da mídia impressa, depoimentos de líderes e fiéis, observações presenciais e programas veiculados pela mídia. Utilizam-se como referencial teórico-metodológico, parâmetros da Nova História Cultural, priorizando-se os conceitos de apropriação, circulação cultural, habitus, imaginário e longa duração. Da análise aqui empreendida, constata-se que a leitura da Bíblia exerce um papel preponderante nas práticas deste segmento religioso ao orientar o comportamento coletivo e configurar um fertilíssimo passado cultural. Na magia dos ritos e na riqueza símbólica ali adotados, percebe-se um substrato cultural legado das crenças afro e da religiosidade popular católica, o qual é sincreticamente re-significado a partir de elementos da tradição evangélica.

Piaget e a predicação universal

O estudo apresentado neste livro trata da relação entre Lógica e Psicologia e parte da questão apresentada na obra Ensaio de Lógica Operatória de Jean Piaget (1896-1980): [...] como se constituem as estruturas elementares de classes, de relações, de números, de proposições, etc., formalizadas com toda independência e autonomia pelo lógico e [...] quais são suas relações com as 'operações' do pensamento 'natural', muito mais pobre e não formalizado.. Os autores Rafael dos Reis Ferreira e Ricardo Pereira Tassinari observam que nessa questão, Piaget pressupõe que as operações lógico-formais estão vinculadas a um sujeito. O que interessa ao pensador francês é a compreensão de como se formam as estruturas necessárias ao conhecimento lógico-matemático e como isso é possível a partir do desenvolvimento psicológico. Eles mostram que, apesar de recorrer à Psicologia, trata-se no contexto dessa investigação de Piaget, fundamentalmente, de um interesse filosófico, relacionado à Teoria do Conhecimento e à Epistemologia, particularmente ao que o francês chama de Epistemologia Genética, e não propriamente uma investigação de pura Psicologia. A questão da relação entre Lógica e Psicologia estudada nesse livro é basicamente de como o sujeito epistêmico usa e se torna capaz de usar funções proposicionais para estruturar a realidade e produzir conhecimento sobre ela. A obra inicia-se com a contextualização do pensamento de Piaget no âmbito das discussões filosóficas e os pressupostos gerais da Epistemologia Genética e suas relações com a Psicologia Genética. O segundo capítulo é dedicado a algumas das discussões de princípios realizadas por Piaget no Ensaio, acerca do objeto e da definição da Lógica Operatória. No capítulo seguinte, os autores procuram responder à questão central do estudo, focando a análise sobre o conceito de função proposicional para Piaget e a relação desta com o ...

Using Universal Line Model (ULM) for Representing Electromagnetic Transients in Three-Phase Transmission Lines

The second-order differential equations that describe the polyphase transmission line are difficult to solve due to the mutual coupling among them and the fact that the parameters are distributed along their length. A method for the analysis of polyphase systems is the technique that decouples their phases. Thus, a system that has n phases coupled can be represented by n decoupled single-phase systems which are mathematically identical to the original system. Once obtained the n-phase circuit, it's possible to calculate the voltages and currents at any point on the line using computational methods. The Universal Line Model (ULM) transforms the differential equations in the time domain to algebraic equations in the frequency domain, solve them and obtain the solution in the frequency domain using the inverse Laplace transform. This work will analyze the method of modal decomposition in a three-phase transmission line for the evaluation of voltages and currents of the line during the energizing process.

Wizard CD Plus and ProTaper Universal: analysis of apical transportation using new software

Objective: This study has two aims: 1) to evaluate the apical transportation of the Wizard CD Plus and ProTaper Universal after preparation of simulated root canals; 2) to compare, with Adobe Photoshop, the ability of a new software (Regeemy) in superposing and subtracting images. Material and Methods: Twenty five simulated root canals in acrylic-resin blocks (with 20 degrees curvature) underwent cone beam computed tomography before and after preparation with the rotary systems (70 kVp, 4 mA, 10 s and with the 8x8 cm FoV selection). Canals were prepared up to F2 (ProTaper) and 24.04 (Wizard CD Plus) instruments and the working length was established to 15 mm. The tomographic images were imported into iCAT Vision software and CorelDraw for standardization. The superposition of pre- and post-instrumentation images from both systems was performed using Regeemy and Adobe Photoshop. The apical transportation was measured in millimetres using Image J. Five acrylic resin blocks were used to validate the superposition achieved by the software. Student's t-test for independent samples was used to evaluate the apical transportation achieved by the rotary systems using each software individually. Student's t-test for paired samples was used to compare the ability of each software in superposing and subtracting images from one rotary system per time. Results: The values obtained with Regeemy and Adobe Photoshop were similar to rotary systems (P>0.05). ProTaper Universal and Wizard CD Plus promoted similar apical transportation regardless of the software used for image's superposition and subtraction (P>0.05). Conclusion: Wizard CD Plus and ProTaper Universal promoted little apical transportation. Regeemy consists in a feasible software to superpose and subtract images and appears to be an alternative to Adobe Photoshop.

The potential of novel primers and universal adhesives to bond to zirconia

Objectives: To investigate the adhesive potential of novel zirconia primers and universal adhesives to surface-treated zirconia substrates.Methods: Zirconia bars were manufactured (3.0 mm x 3.0 mm x 9.0 mm) and treated as follows: no treatment (C); air abrasion with 35 mu m alumina particles (S); air abrasion with 30 mu m silica particles using one of two systems (Rocatec or SilJet) and; glazing (G). Groups C and S were subsequentially treated with one of the following primers or adhesives: ZP (Z-Prime Plus), AZ (AZ Primer); MP (Monobond Plus); SU (ScotchBond Universal) and; EA (an Experimental Adhesive). Groups Rocatec and SilJet were silanized prior to cementation. Samples form group G were further etched and silanized. Bars were cemented (Multilink) onto bars of a silicate-based ceramic (3.0 mm x 3.0 mm x 9.0 mm) at 90 degrees angle, thermocycled (2.500 cycles, 5-55 degrees C, 30 s dwell time), and tested in tensile strength test. Failure analysis was performed on fractured specimens to measure the bonding area and crack origin.Results: Specimens from group C did not survive thermocycling, while CMP, CSU and CEA groups survived thermocycling but rendered low values of bond strength. All primers presented a better bond performance after air abrasion with Al2O3 particles. SilJet was similar to Rocatec, both presenting the best bond strength results, along with SMP, SSU and CEA. G promoted intermediate bond strength values. Failure mode was predominately adhesive on zirconia surface combined to cohesive of the luting agent.Conclusions: Universal adhesives (MP, SU, EA) may be a considerable alternative for bonding to zirconia, but air abrasion is still previously required. Air abrasion with silica particles followed by silane application also presented high bond strength values. (C) 2013 Elsevier Ltd. All rights reserved.

With the advent of technology, many repetitive processes before now was be simplified with the support of a simple computer. Therefore programming has been developed and new softwares appear every day. For the development of this project was used the Microsoft Visual Studio 2010, and with it the program was made in C # Windows Form mode. This work aims to develop a program that can read, send and receive data via the Universal Serial Bus (USB) to the computer, and thereby perform the processing. Thus the milk producer will possess the knowledge of the amount of milk produced by the animal. With the processing of data it is possible to generate graphs of herd production or a specific animal and you can also generate the required report date

Universal or provincial? early reception of brian friel´s philadelphia, here I come!

This article, part of a larger research work that resulted in a Professorship Thesis, presents a survey and evaluation of the early reception of one of Brian Friel’s first plays: Philadelphia, Here I Come! (1964). The article also explores the question of emigration from Ireland in the 1950s and 1960s, considering British legislation on the matter, and comments on the eventual influence such issue, among other factors, may have had on criticism about the performance of the play at the time.
