Avaliação de fração volumétrica de austenita retida e martensita em aço trip 800 utilizando três métodos diferentes

In the second half of the last century the automobile industries suffered from the petroleum crisis caused mainly by the wars in the Middle East. These crises led the automakers rethink their vehicles. One of the most important events after that was the adoption of new steels by the industry. One example is the TRIP steels (Transformationinduced plasticity). It is known that the macroscopic behavior of a material is strongly dependent on its microstructure and therefore the quantitative metallography is important to understand and relate the material properties to its microstructure. In this work, different specimens of TRIP steels were etched using LePera reagent. The obtained images were analyzed using digital processing. Using the ImageJ software the methods threshold and watershed were studied as well as a comparison with the ASTM E562 standard. The methods were compared and finally the morphological characteristics and volumetric fraction of the retained austenite and martensite phases were analyzed. The results showed that the threshold led to a higher number of identified grains with lower mean area and total area fraction than the watershed method and ASTM standard

A evolução histórica do lançamento do dardo: base para o ensino do atletismo em aulas de Educação física

Ainda que pouco conhecida, a história do lançamento do dardo revela ser esta uma prova muito antiga, existente desde os Jogos Olímpicos da Grécia Antiga. Com base nisso, o objetivo desta pesquisa consistiu em resgatar a história dessa prova do atletismo, observando seu desenvolvimento ao longo dos anos, sobretudo no que diz respeito às alterações em suas regras, em seus implementos, em seus resultados, entre outras coisas. Com base em livros, documentos, registros de competições e fotografias de diferentes épocas, essa pesquisa histórico-bibliográfica procurou coletar o maior número de dados que nos permitem compreender e analisar o desenvolvimento da prova do lançamento do dardo até os dias atuais. Entre outras coisas, os resultados evidenciam o surgimento do lançamento do dardo a partir da necessidade de sobrevivência do homem, sendo utilizado, sobretudo, em suas atividades de caça e guerra, no período da Pré-História. No período da Antiguidade Clássica, há registros que comprovam a utilização do dardo por infantarias e cavalarias, na Grécia Antiga, no Império Romano e pelos Lusitanos. Entretanto, além das guerras, o dardo era também utilizado nesse período em atividades esportivas. O lançamento do dardo era praticado de duas diferentes formas nessa época: o lançamento do dardo em um alvo prédeterminado (traçava-se um círculo com a distância desejada e o atleta deveria fazer o dardo cair dentro dele). Esse tipo de lançamento ocorria a partir de um ponto fixo que, muito provavelmente, era a linha de partida do estádio (stádion), chamada de “balbís” - e o lançamento do dardo em um alvo predeterminado (que acontecia geralmente em cima do cavalo, e o cavaleiro deveria...

Diagnóstico geoambiental e avaliação de risco à saúde humana para uma área industrial contaminada por hidrocarbonetos localizada no município de Paulínia (SP)

This paper deals with a case study of assessing risk to human health, with the study area of an industrial site in the city of Paulinia (SP) contaminated by oil, which is disturbing situation that occurs in the state of Sao Paulo, which represents risks for human health, as toxic and carcinogenic potential of petroleum products. As an essential foundation for risk assessment, a Geo-environmental diagnosis of the region was made, posing as historical information of the area and accidents, regional geology and hydrogeology, characterization of contaminants and affected media, contaminant transport and data on potential receptors and pathways. Because of the detection of contaminants above the intervention values CETESB (2005) it was possible to proceeded to quantify risks to human health and the determination of maximum acceptable concentrations for no damage to health, using the methodology and software RBCA Tier 2 (ASTM , 1998) and Spreadsheet Risk Assessment recently published by CETESB. The results showed the risk to the health of industrial workers and regular employees of civil works (both on site) for ingestion of groundwater and inhalation of vapors indoors.

Due to the large number of pathologies in the civil constructions justified to highlight the reasons for problems encountered and subsequently the most appropriate way of implementing procedures for certain services performed in civil construction. The intention here is to explain each of the subjects studied, identify and distinguish the conditions presented in the post delivery of civil constructions from construction X, through research and company documents, and highlight steps of the executives of some services civilians highlighted in this work to minimize, or cancel, future maintenance. Studies will be conducted in a more narrow, focused more specifically in the most happening pathologies in the constructions and how to perform each service to prevent future problems with masonry (non-structural cracks and crevices), waterproofing, window frames and cladding. Thus, this study seeks to protect the building, using material technology and equipment, to allow an increase in the service time of the building,

Durabilidade da argamassa mista de revestimento interno contendo dregs-grits em substituição à areia

This paper concerns about the durability of new material in construction. It is noteworthy the fact that increases increasingly searching for alternative materials that do not depend only of natural resources and at the same time be an alternative for reuse of industrial waste. Since the construction materials have a long life and a high cost of civil works and maintenance, it is crucial to estimate the behavior of a new product. Thus , this work discuss the durability of mixed mortar lining , made with waste from the process Kraft pulp production , known as dregs and grits , in partial replacement of sand. Tests were conducted to simulate conditions as adverse environments of constant heat and fire, with the aim of analyzing the behavior of mortar mixed matched the behavior of standard mortar

Práticas corporais complementares: um estudo sobre a antiginástica

The concept of physical education emerged in the XIX century through the European gymnastic methods, initially for the purpose of asserting the sovereignty of the nationality of countries, by means of exaltation of patriotism of the masses and the physical preparation for military wars. Nowadays, the cult of the ideal body has changed, becoming the unceasing desire within each society, according to its characteristics of established standards, most of the time denying the genetic determinations of each ethnicity. This social phenomenon has generated openness and encouragement to the fitness market on the rise, eager in supporting the aspirations of the cult of the body”, representing the huge seek of the idea of a healthy body and an aesthetic appearance acceptable in today's society. Parallel to this, the Body Awareness Gymnastics, also known as Technical or Complementary Practices, were introduced in Brazil in the 70s, presenting as main themes the body awareness, the mind-body relationship, and against the ideals of body training. According to authors, the pioneering technique of the movements of alternative practices in Brazil was Antiginástica of Thérèse Bertherat. Therefore, this study aims to harmonize the complementary body practices of the physical education area through literature review of published works by the author Thérèse Bertherat, entitled The body has its reasons, The body communication system, Stations of the body, The Tiger´s Den and When the body is consent. The work also includes the contribution of a particular reading of the researcher, from the experiences of the practices carried out in order to enrich the reporting work through their records, the results obtained from the experiential process

Os Statalismes - particularismos lexicais do francês da Suíça na tradução juramentada

Este estudo, de natureza teórica/aplicada, contempla os estudos (sócio) linguísticos, (sócio) terminológicos, do léxico e da tradução especializada. Tem como objeto de estudo um corpus de textos submetidos à tradução/versão juramentada francês-português e um corpus de textos originalmente redigidos em francês da Suíça. O objetivo é observar as aproximações e distanciamentos existentes entre o primeiro e o segundo conjunto terminológico. A problemática situa-se na verificação da confrontação desse material: será que os particularismos lexicais do francês suíço determinariam uma dificuldade relevante no trabalho do tradutor brasileiro, cuja formação privilegia o francês da França? Nossos resultados revelam diferenças significativas de uso e perigosos falsos cognatos. A metodologia para o levantamento dos particularismos na variante suíça presentes em documentos civis ou escolares privilegia os termos cognatos e aqueles com o status de ‘statalismes’ (romandismos institucionais).

Quando gestos não políticos são políticos: a tradução brasileira de Giovanni's Room, de James Baldwin, e a questão da homossexualidade

This work is part of a research project on the role of translations of African-American literature in Brazil and their relation to issues of identity, discourse and aesthetics. It analyzes the translation, by Affonso Blacheyre, of Giovanni's room (1956), by James Baldwin, which was published in 1967 in Brazil. Baldwin is revered for his role in the Civil Rights Movement, having produced works that portray the contradictions of a democratic, but, at the same time, racist society. Giovanni's room was first rejected by his publisher for addressing homosexuality. The text displayed on the book flaps of the translation praises Baldwin's "work with language", in contrast to his anti-racism in other works. The praise of aesthetics of Giovanni's room is noteworthy, in contrast with the absence of any remarks on its critique of the marginalization of homosexuality. The focus on the aesthetics of the work corresponded to characters speaking a more formal register in the translation. Discourses on identity strengthening were less apparent in the 60s in Brazil in comparison to nowadays. The emphasis on aesthetics represented a seemingly "non-political" gesture that made it less shocking in the context of military dictatorship prevalent in the country at the time.

Projeto e implantação de pequena central de geração hidrelétrica: análise de caso

The objective of this work is to study the implantation feasibility of a small hydropower system in a rural area in Guaratinguetá. Due to its location and accessibility, and the costs involved in extending the public distribution line to the property it could turn become viable the construction of an individual electric generation system. As alternatives, a solar photovoltaic system and combustion engine-electric generator systems were considered. However, the existence of a small river inside the property, the construction of a micro hydropower plant was taken into account. The choice of the micro power hydropower plant was determined by the owner and was based on the costs. The topographic and hydrological profiles as well as the geometrical characteristics of the system, including the civil infrastructure needed and the more adequate turbine, were determined. Finally, the cost spreadsheet was set and the results were compared with those calculated for the extension of the available public distribution system
