There is a need for ongoing evaluation of the researchers not only engineering and production in all areas of knowledge engineering. To check the quality and veracity of scientific production, the CNPq is a brazillian government agency designed to evaluate researchers, classify them and give the encouragement and incentive for their research. This study quantifies the CNPq researchers in the field of Production Engineering according to the time of operation in research, number of guidelines for masters and doctoral, number of articles in national and international journals or magazines and congresses. The classification of these researchers, according to the proposed quantification, is confronted with the level of research they have in CNPq. The researcher starts his career at level 2, after it spending levels for 1D, 1C, 1B reaches to the highest level 1A. The main conclusion to be drawn from this study is that excellent researchers with a significant number of guidelines, bitter years in the early levels because of the rules of the CNPq which only allows a researcher to achieve the highest levels after many years of research

The current work aims to analyze the contributions of PIBID for initial graduation of the teachers, in view of the undergraduates of Physics Course at UNESP Guaratinguetá . A brief literature survey about the national situation of teacher education was performed, at which the main difficulties and challenges, as well as the solutions stated in place by the government to solve them, have been highlighted. A description of the historical of PIBID at UNESP, from the institutional project to reach the subproject developed by Physics Course of Guaratinguetá, was presented. To characterize the development of the subproject, it was performed a survey on the activities performed by the PIBID’s scholars, since its implementation on campus in 2010 until the end of the year 2013, in order to map the experiences lived by program participants. These data were obtained from the analysis of reports by scholars themselves, video analyzes and record of the weekly meetings held by the group, reading electronic messages exchanged on a specific group of e-mails and written evaluations by members of the program. Completing data collection, eleven scholars undergraduates of the program were interviewed, and the results were classified by topics, defined from recurrence in the interviewees speech. The global analysis of the data was based on theoretical references commonly used in research on graduation of teachers, as Nóvoa (1992), Mizukami (2005, 2006) and Gatti (2008). The results indicate that the licensed ones see in PIBID a differentiated opportunity for initial teaching graduation, for adding practical learning experiences for students of EB within the school context, and especially for creating space for reflection on their experiences with the support of more experienced teachers, committed to the training of all involved ones

The number of piping in an industry is high. Through this piping are conducted several kind of products at several temperature and pressure conditions. In a chemical company, the piping quantity conducting harmful chemical products to human health and to the environment is higher. Nowadays the theme sustainability is often mentioned and harm to environment may cause irreversible damage to the human being, to the fauna, to the flora and to company´s credibility. In this context, controlling over the piping to avoid accidents is mandatory. The objective of this monograph is to create a procedure which enables the chemical companies piping traceability. This monograph analyses the several existent traceability system in the three economy sectors and approaches the technical question of industrial piping in order to create a procedure that achieves its objectives as a technical document and at the same time be economically feasible, with low complexibility level and high practicability. Some possibilities to elaborate this procedure had been studied, as the creation of an alphanumeric code and making with a chisel in the pipeline based on ASTM F2897 and the use of chips to store the information. However, the procedure which best meet the requirement as low cost and high applicability is filling out an electronic plan with information about welding process, welding certification, welding consumables and inspections

The oil extraction in deep waters sparked new areas of knowledge, the creation of engineering courses dedicated just to these processes and a wide field of analysisvoiding multiple impacts in case of faults, mainly the economic and environmental. This paper aims to show on the effects and causes of fatigue failure in steel tubes used for oil and gastransportation (linepipe), mainly caused by vortex induced vibrations, or VIV. To make this, through laboratory tests, it found trough the curve Stress versus Number of Cycles, and thus estimating that with a stress value of 350 MPa or less, the fatigue life cycle of the API 5CT T95 (1% Cr) pipe is estimated infinite. It could conclude that the analyzed material has good fatigue failure resistance for offshore use, taking into account only the influence of VIV's, since there are no stress concentrators

The transportation of oil through polyducts implies a concern related to safety and environmental impacts they may cause, especially when exposed to risks that affect their integrity. Among the various anthropogenic activities included in this scenario, mining can aggravate, increase the risks and degrade the environment. Since these polyducts go through significant extensions, remote sensing has great applicability as a tool for data acquisition. For this, change detection techniques were used to monitor mining activities in a defined study area in the state of Rio de Janeiro, along the duct ORBEL. The characterization of the study area and the mining activities were developed through bibliographical data. The satellite images processing and the application of change detection technique were performed in two scenes for the years 2002 and 2010. The growth in the mining area was about 6.67 times and it was possible to identify types of extraction involved which can represent direct risks to the pipeline

The research addresses the need for detailed geological and geotechnical investigations in pipeline’s design, given the diversity of geological units crossed by these works along its layout, which often extends for hundreds of miles. For its large size, this type of work often goes through different states and regions with very different characteristics in terms of topography, vegetation, geology and geotechnical conditions. For a better use of these investigations in order to avoid unnecessary costs and inefficient results, some authors recommend that steps be taken to study, seeking a progressive detail of the pipeline’s implantation area. The main objective of the study is to describe, analyze and correlate the proposals for geological and geotechnical’s investigation recommended by the authors selected. Nogueira Junior & Marques (1998) suggest that for better effectiveness of geological and geotechnical investigations associated with the deployment of pipelines, different research methods are applied sequentially in five major stages of the building. Rocha et al (2008) recommend that, for the pipeline’s implantation using horizontal directional drilling, investigations are performed in three phases of study, to be developed in coordination with the project stages. For Gelinas & Mathy (2004), when time and budget constraints permit, geotechnical investigations for directional drilling projects for pipelines must be made in four sequential phases. Heinz (2008) suggests that the geotechnical investigations for pipeline’s implantation using horizontal directional drilling at crossings of water bodies are carried out in three successive stages. By the development of research, we could see that all the different proposals recommend studies in sequential phases, starting from a more general scale for a more specific, seeking a progressive understanding of the geological model of the area where you intend to deploy the pipeline

The gas turbine (GT) is known to have: low cost of capital over the amount of energy, high flexibility, high reliability, short delivery time, commissioning and commercial operation at the beginning and quick departure. The gas turbine is also recognized for its superior environmental performance, manifested in air pollution containment and reducing greenhouse gases (Mahi, 1994). Gas turbines in simple cycle mode (SC) have long been used by utilities to limited power generation peak. In addition, manufacturing facilities use gas turbines for power generation units on site, often in combination with the process of heat production, such as hot water and steam process. In recent years, the performance of industrial gas turbines has been improved due to significant investments in research and development, in terms of fuel to electricity conversion efficiency, plant capacity, availability and reliability. The greater availability of energy resources such as natural gas (NG), the significant reduction of capital costs and the introduction of advanced cycles, have also been a success factor for the increased use of gas turbines to load applications base (Poulikas, 2004). Open Cycle Gas Turbine with a greater degree of heat to the atmosphere may alternatively be used to produce additional electricity using a steam cycle, or to compose a cogeneration process. The combined cycle (CC) uses the heat from the gas turbine exhaust gas to increase the power output and increase the overall efficiency of more than 50% second (Najjar, 2001). The initial discovery of these cycles in the commercial power generation market was possible due to the development of the gas turbine. Only from the 1970s that gas turbine inlet temperature and therefore the exhaust gas temperature was sufficiently high to allow a better efficiency in the combined cycle ...
