Análise dos métodos de cálculo de golpe de ariete em tubulações

This work studies the most commonly used methods and make comparisons and discussions of the findings made by each of them and the results provided by them. The objective of this research was to show that the method of characteristics is currently the most efficient method to perform these simulations because of its broad scope low simplifications, requirement allowing to consider every detail of the pipe and fluid. Manual calculations are performed and also a software capable of calculating this phenomenon for various situations, such as water pump, elevated tanks, valves and quick maneuver was developed. The software is based on the method of characteristics that is currently recommended by ABNT. These methods, and the results are obtained numerically and graphically are adopted pipes and amount of downstream conditions and in which will be applied. The conclusions reached showed that the Allievi method is widely used yet because of its efficiency and quick calculation for simple pipes. The method of characteristics, although a lot of work to be calculated due to the calculation is iterative process and requires a program to use it, is the only one that allows the calculation with all amount to the conditions situations and downstream of all the pipe possibilities found

A função social da escola e a constituição da forma escolar (Brasil/Portugal, 1870-1932)

O artigo analisa aspectos das relações entre a escolarizaçãoe os processos culturais mais amplos, tomando como fontedocumental manuais didáticos produzidos para uso em cursos deformação de professores, que circularam no Brasil e em Portugalno período final do século XIX e no início do século XX. Foramfocalizados elementos passíveis de generalização, entre eles aunidade da forma escolar e as diferentes práticas prescritas aosprofessores, destinadas a enraizar valores e ideais no processoformativo. Foram analisados os seguintes manuais: CursoPractico de Pedagogia, de autoria de Mr. Daligault (1874);Elementos de Pedagogia, de autoria de Jose Maria da GraçaAffreixo e Henrique Freire (1870); e Lições de pedagogia gerale de história da educação, de Alberto Pimentel Filho (1932).

Das formas de ensinar e conhecer o mundo: lições de coisas e método de ensino intuitivo na imprensa periódica educacional do século XIX

This article analyses A Eschola Publica, an educational journal that circulated in São Paulo state between 1893-1894 and 1896-1897, whose editors, allied with the diffusion of republican ideas, helped the consolidation of objective method as a pedagogical efficient modern tool. It was possible gathering some sources that shows the acceptance of that method and the difficulties for its dissemination in the classroom, mainly those refers to teacher’s formation. Taking as referential bibliographical resources about schooling culture it was possible verifying that circulating in complementary parallel way to textbooks, the articles by A Eschola Publica endorse the innovative purposes and show barriers imposing on educational context. This journal produced a place for discussions and debates that contributed for controlling and producing symbolic resources

A divulgação do pensamento saussuriano no Brasil

The ideas of Ferdinand de Saussure (1857-1913) still stimulate keen interest among language scholars today, be it complementary or contradictory. Saussurean thought has become widespread, in a more or less explicit manner, in undergraduate and graduate education in the humanities. Since the mid-1950s, Saussure’s ideas have been introduced and debated as part of the training of first-language and foreign-language teachers, communicators, anthropologists, sociologists and psychologists. In the majority of undergraduate and graduate disciplines in the areas of Linguistics and Communication, from the moment academics begin to address the nature of human signification and communication, it is impossible to ignore Saussure’s reflections on language and parole. The aim of this study is to reflect on the transmission of the general lines of Saussurean thought in Brazil. For this purpose, an inventory and analysis are carried out of Linguistics manuals originally published in Brazil since the 1970s, with the aim of reflecting on their construction in terms of programming and persuasion, categories of analysis of didactic speech proposed by A. J. Greimas.

Uma amostra do tratamento concedido às classes de palavras na tradição gramatical do português

Within a broader study of the apparatus governing the establishment of word classes in grammatical tradition, this study is centered on examining the treatment of the (sub)class of pronouns in two grammar guide groups from different periods. The collation was especially oriented by the existing general notion of a very strong link of the first grammarians with logic and, as a counterpart, of an insertion of the most recent works in the universe of a linguistic science and, at the same time, in the universe of a parameterization limiting actions and decisions.

O engavetamento de modelos de ensino superior dentro da universidade pública

This paper explores the contradictions between models conflicting today in Brazilian universities. The conglomeration of isolated institutions, integrated and multifunctional university and university-enterprise, service provider. This last model attempts to integrate higher education institutions to supply chains dominated by capital. Public universities were designed to provide innovative services and train staff researchers for such activity. The training of skilled workforce would be fundamentally task of private universities. But in any case, the onus would be on this training students. This model has been driven from the 1990s, with "instruction manuals" of the World Bank, and in 2000, with the IMF recommendations and, in the case of Latin American universities, Fundación Universia, sponsored by the Santander Bank. The question remains: the university will be able to organize the productive forces which have around research goals and staff training for independent development.

Efeito do ângulo de trabalho do ultrassom e do jato de bicarbonato sobre as superfícies ranculares

The aim of this study was to evaluate the effect of the working angle variation of the magnetoestritive ultrasonic (MU) and air polishing devices (APD) on the roughness and wear of dental root. Fifty bovine incisive teeth were used in this study. The proximal surfaces of the teeth were divided in three regions: coronal, median, and an apical. The coronal region was treated with a manual scaler, the apical region was treated with APD or with a MU and the medium region was maintained untreated to serve as a control. The teeth were divided in 11 groups according to the treatment applied: MU-0º; MU-30º; MU-45º; MU-60º; MU-90º; AP-0º; AP-30º; AP-45º; AP-60º; AP-90º; MS: manual scaler. To the statistical analysis, data submitted to the Anova and Tukey's test (p < 0.05). The manual curette promotes less roughness and higher tooth wear in comparison with the both ultrasonic and air polishing devices (p < 0.05). The angles of 45º, 60º and 90º caused higher rate of tooth wear and roughness when the MU was used (p < 0.05), while the angle of 90° caused a higher tooth wear than the angle of 30° when the APD was used (p < 0.05). The working angle variation influenced the tooth wear and roughness promoted by MU, whereas when using APD, the working angle variation influenced only the tooth wear.

Um percurso pela psiquiatria infantil: dos antecedentes históricos à origem do conceito de autismo

This article is a conceptual study that aims to trace a historical course of the psychiatric knowledge about children, pointing how the conceptualization of autism will lead into this prospect. For such, we divided this work into three parts: the first is dedicated to the discussion of the concept of mental retardment, followed by the questioning of the first reflections on the psychoses of childhood and the birth of the Child Psychiatrist clinic and the conceptualization of autism by Psychiatry. Therefore, we seek to understand the meaning and origin of current practices, critically analyzing the psychiatric manuals and its impact on child psychopathology.

Avaliação e correlação da presença de endotoxinas e MMP-3, -8 e -9 em canais radiculares com necrose pulpar submetidos ao tratamento endodôntico - estudo in vivo

It is know that endotoxin and various matrix metalloproteinases (MMPs) are involved in the development of periapical lesions. The purpose of this study was to evaluate and correlate the presence of endotoxins and MMP- 3, MMP-8 and MMP-9 in root canals of teeth with necrotic pulp and periapical lesion before, during and after the biomechanical preparation (PBM) using a combination of different irrigations solutions and intracanal dressing. Thirty-three single-root teeth with a diagnosis of pulp necrosis and periapical lesion radiographically visible were selected. Immediately after the coronal opening was collected the first sample from the root canal content. Then, all canals were prepared (cervical and middle thirds) by oscillatory instruments (EndoEze) and irrigated by 2.5% NaOCl. After, a manual preparation was made for the apical third and the teeth were divided into three groups according to the irrigation protocol: G1) 2.5% NaOCl (4 manual files); G2) 2.5% NaOCl (2 manual files) + [Ca (OH)2 0.14%] (2 manual files) and G3) 2.5% NaOCl (2 manual files) + polymyxin B (2 manual files). After the PBM, the second sample was collected; then the third collect was performed after using EDTA final flush. The fourth sample was collected 14 days after placing the dressing [2% chlorhexidine gel + Ca(OH)2]. Quantification of endotoxins was performed by a kinetic chromogenic lysate from amoebocytes of Limulus (LAL) and quantification of MMPs by ELISA assay. The results were analyzed statistically by Kruskal-Wallis and Dunn's test (5%) and ordinal Spearman correlation. Presence of endotoxin was observed in 100% of cases and G3 showed the greatest reduction of endotoxins from the 1st to the 2nd samples (97%), being statistically similar to G2 (84.2%) and different from G1 (49.4%) (p<0.05). The intracanal dressing promoted a significant reduction of endotoxin, no difference among the groups. For...
