Pressure vessels are equipments that require a great care because of their high cost and human life risk in case of fail, and its fabrication methods are different for each manufacturer. Normally, pressure vessels and its parts are fabricated by welding, which may change local properties of metals. The head of a pressure vessel is a very important structural component and it is fabricated by welding and mechanical conformation. Because its excellent mechanical properties, de steel A-516 Grade 70 is often used in manufacturing of large pressure vessels that are subjected to high pressure and temperature, but was verified that its mechanical resistance is decreased when submitted to a tension relief heat treatment. By experience it was defined that before mechanical conformation of the head of a large pressure vessel, the steel should be submitted to a stress relief heat treatment in order to facilitate the mechanical conformation, but there is no quantitative analysis to prove this method and study its possible risks. In the present work the steel A-516 Grade 70 demonstrated a decrease of its mechanical resistance when submitted to a stress relief heat treatment, but keeping above the minimum limit defined in the literature. By other side its ductility was substantially increased, being possible to deduce that the stress relief heat treatment before mechanical conformation is a viable e recommended technique, but with reservations. With the data acquired during the fabrication e preparation of the specimen and the result of the tests, it was possible to elaborate a welding procedure that provides the same results obtained in this present work

This work focuses on a study on the fatigue behavior of a microalloyed steel API 5L X70, used in pipes lines to transport oil and gas. These types of steels have excellent mechanical resistance values and ductility and therefore increased their study driven by increased demand for oil and especially natural gas, which consequently raises the need to build new pipelines to transport these products. The oil extraction units, composed of the risers (pipelines connecting the oil well to the ship), are dimensioned to remain installed for periods of 20 to 30 years in the marine environment, a hostile environment for high pressure, corrosion, low temperatures and the stresses caused by the movement of water and tides. For analysis, the S-N (stress versus number of cycles) curves were obtained from data collected from bodies-of-proof cylindrical longitudinal, transverse and that one removed from the weld area of the pipe, tested in accordance with ASTM E466. Tensile tests were performed for characterizing the mechanical properties of the samples and welded joints, concluded that the values meet the specifications of the standard API 5L. To characterize microstructural material, also metallographic analysis was made of regions of the base metal and the HAZ. The results of fatigue tests demonstrated a higher life for the specimens removed from the longitudinal direction the pipe, followed by those in the transverse direction and, finally, the welded joint. The origins of the fatigue cracks were determined by scanning electron microscopy (SEM)

This work aims to evaluate the different trajectories in terms of production structure, technological capabilities and performance in international trade of pharmaceutical industries in Brazil and India. For this, we build international trade indicators, based on data provided by the COMTRADE, the UN database for trade. Through the indicators, it is observed that the countries have different results in the catch-up process of the pharmaceutical industry. India has built a productive structure strongly based on generic drugs, with which it is able to greatly meet domestic demand and export to many countries worldwide. Brazil remains in a position of dependence of foreign production, with a high level of imports and exports to the region of Latin America

This study was developed based on Classical Greek Language classes, reading and translation of texts. There is also the presence of computer elements due to use of Alpheios digital platform. As an example of a larger proposal, this proposal aims at produce translation aligned with the Portuguese and syntactic annotation with the production of the Greek dependency trees. To achieve the goal, we chose Chapter 34, Volume 1 of The Histories from Herodotus. The methods adopted contain a list and description of the instruments and the morphological categories from the guide (manual rules of syntax tree). The procedures adopted are the description of the alignment process and of syntactic annotation. As study results, we have the production line translation and the syntactic annotation of the excerpt 1.34. It was concluded that the study of this text is relevant, because the lexical density of Herodotus it's interesting at future researchers and students that will use the digital platform Alpheios

Destruction of bone and periodontal ligament as a result of periodontal disease can lead to anatomical defects in the furcation area. Treatment of these lesions is a major challenge to the clinician. Periodontal instruments have limited access to this area and plaque and calculus removal from root surfaces are extremely difficult. For proper treatment planning a number of factors must be taken into consideration to achieve immediate and long term success. Surgical therapy associated with bone grafts may be a viable option in the treatment of class II furcation defects, aiming to restore lost tissues. The aim of this paper is to report a clinical case where a simplified surgical approach with the use of autogenous graft was used to treat a class II furcation defect Twelve months after the surgery, an increase in clinical attachment level and pocket depth reduction resulted in a complete closure of the furcation lesion.

Objetivo: Examinar o padrão de consumo do tabaco e conhecimentos sobre as doenças relacionadas ao tabaco, assim como identificar os tipos mais populares de mídias entre gestantes para aprimorar estratégias para a prevenção e a cessação do tabagismo entre essas mulheres. Métodos: Estudo transversal com 61 gestantes atendidas em um hospital universitário e em unidades básicas de saúde em Botucatu, SP. A Escala Hospitalar de Ansiedade e Depressão foi aplicada a todas as participantes. Para aquelas com história de tabagismo, também foi aplicado o Teste de Fagerström para Dependência de Nicotina, e foi avaliado o grau de motivação para cessação tabágica nas fumantes. Resultados: Das 61 gestantes avaliadas, 25 (40,9%) eram fumantes (média de idade, 26,4 ± 7,4 anos), 24 (39,3%) eram ex-fumantes (média de idade, 26,4 ± 8,3 anos), e 12 (19,8%) nunca fumaram (média de idade, 25,1 ± 7,2 anos). A exposição passiva foi relatada por 39 gestantes (63,9%). Das 49 fumantes/ex-fumantes, 13 (29,6%) conheciam as consequências pulmonares do tabagismo; somente 2 (4,9%) conheciam os riscos cardiovasculares; 23 (46,9%) acreditavam que fumar não causa nenhum problema para o feto ou o recém-nascido; 21 (42,9%) consumiram álcool durante a gestação; 18 (36,7%) relataram aumento no consumo de cigarros quando bebiam; 25 (51,0%) experimentaram cigarros com sabores; e 12 (24,5%) fumaram narguilé. Entre as 61 gestantes avaliadas, a televisão foi o tipo de mídia mais disponível e favorita (85,2%), assim como a mais preferida (49,2%). Conclusões: Entre gestantes, o fumo ativo, o fumo passivo e o uso de formas alternativas de consumo de tabaco parecem ser altamente prevalentes, e tais mulheres parecem possuir poucos conhecimentos sobre as consequências do uso de tabaco. Programas educacionais que incluam informações sobre as consequências de todas as formas de uso de tabaco, utilizando formatos novos e efetivos para esta população específica, devem ser desenvolvidos para promover a prevenção/cessação do tabagismo entre gestantes. Amostras adicionais para explorar diferenças culturais e regionais são necessárias.
