The collective purchases translate into new business strategies that so far are poorly studied, but they have modifyied considerably the forms of consumption through the consumers individualisation, which causes changes in society's routine. The analysis of the theme was performed by study cases of collective shopping places in the city of Campinas, country of the state of São Paulo, and on its influence in the metropolitan area, which intented to understand, through custumers interviews, the contradictions and peculiarities of this service that has increased each day more . For this purpose, the research methodology is focused on the consumer , that's because the process of productive change tied to forms of trade and distribution of goods have been transforming social values considerably, based increasingly on impulsive consumming . Thus, to understand how the electronic commerce and more specifically the collective shopping websites works, it's necessary to examine the forms of commerce and the consumer's behavior in order to explain the city organization and the contradictions of the geographic space

This research aims to discuss the division of royalties from a legal perspective and its substitute role towards the non-taxation at source, in other words the taxation of destiny at the Brazilian petroleum industry. The analysis aims to deal with the historical evolution in relation to the aspect of royalties’ payment and its deviation of compensatory character in order to supply the ICMS function. There are some specific study objects in this research: 1. how the transformation of royalties’ payment led to financial compensation; 2. to whom the transference of mineral rent belongs – to the UNIÃO or to the fortunate regions which the oil is extracted; 3. would a tax reform be enough to minimize the competition of States and Cities towards the royalties? The research aims to clarify the real expectation that States have on the royalties’ payment. There is no compensation for damage to the environment as it is stated by the initial characteristic of the Constitution, and, by the contrast, from a compensatory character, there is a lacking of taxation from the sector mentioned before, this fact damages the producing states checked out by this research

O sistema estuarino do Rio Curimataú, uma planície lamosa amplamente coberta por vegetação de mangue e relativamente pouco impactada, foi estudado quanto à distribuição espacial da microfauna de foraminíferos e suas condicionantes. Vinte e cinco gêneros e quarenta espécies foram identificadas a partir dos sedimentos superficiais, considerando-se os indivíduos vivos e mortos presentes em 10 pontos ao longo do estuário, dos quais se extraíram ao menos 100 espécimes por amostra. O sistema pôde ser compartimentado em quatro sub-ambientes halínicos (hiperhalino, mesohalino, polihalino e euhalino), correspondentes, respectivamente, a quatro ecofácies de foraminíferos designadas de Ammotium spp., Miliammina fusca, Arenoparrella mexicana e Ammonia spp. Cada um destes segmentos ambientais foi caracterizado segundo os padrões de riqueza, diversidade e equitatividade das espécies. Os resultados deste estudo poderão servir para comparações a serem feitas com outros estuários tropicais modernos (impactados antropicamente ou não) e antigos. Tem aplicação, portanto, no setor de petróleo e gás, sendo de interesse às atividades de gestão ambiental de áreas litorâneas e de investigação da história geológica das bacias sedimentares

This article aims at presenting part of the results of a terminological study concerning the sworn translation of enforceable instruments into Portuguese. Our study corpora are comprised of translated documents and texts originally written in English and in Portuguese (bill of lading, invoice and promissory note). The software WordSmith Tools generated the wordlists and we selected the term candidates from these lists. The proposed glossaries presents, apart from simple terms, fixed or semi fixed expressions, the cotext (text around the search word) extracted from the studied corpora. It was observed that most part of the fixed or semi fixed expressions are not shown by the specialty dictionaries.

Brazil has a strong trading relationship with several countries, including France, which has intensified these links in recent years and intends to do so yet further. Legal documents regulate this operation, resulting in a set of terms which designate concepts specific to this area. Communication between Brazilian and French buyers and sellers is intense and does not permit the occurrence of errors in understanding orders for merchandise nor in terms of purchase and sale. It is therefore very important that agents of International Trade between Brazil and France should have access to a specialised terminographic tool in the area, containing the relevant terms used in French and Portuguese. This type of work does not currently exist; we therefore decided to make a contribution and draw up a proposal for a bilingual French-Portuguese dictionary in this specialised area. During our research, we registered a significant presence of English terms in International Trade texts originally written in Portuguese and in French, which may be explained by the fact that English currently has the role of global lingua franca. However, it is well known that France operates a policy of linguistic protectionism, making the use of French obligatory in all sectors of activity in France. This generated an area of doubt: how should one deal with English terms in a bilingual French-Portugese dictionary? In order to begin the search for an answer to this question, we decided to see what treatment was given to English terms in the area of International Trade in some French dictionaries. In this paper we shall present the principal results obtained during our research.

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 ...

On the grounds of the great advances achieved over recent years, the process HF/ERW (High-Frequency/Electric Resistance Welding)welded pipe have played an active role in the oil and gas industry for deep water applications, at high and extremely low temperatures, under high pressure and in highly corrosive environments, gradually replacing manufactured pipes by other processes. However, studies have shown that defects in the welded joints are a the leading causes of pipelines failures, which has required the determination of toughness values in this region, in compliance with the strict recommendations of the codes and standards with manufacturers and construction companies, on the oil and gas sector. As part of the validation process required toughness values, this research project focuses on a microstructural analysis in HF / ERW tubes microalloyed, steel grade API 5CT N80, designed to explore oil and gas in deep waters, the subject of strategic relevance to the country because of the recent discoveries in the Santos mega fields: Tupi and Libra (pre-salt). In this scientific work will be presented and discussed the results of mechanical tensile and Charpy, a few CTOD tests curves (showing the trend of toughness values to be obtained), and the microstructures of the base material obtained by optical microscopy, with special emphasis on the formation of non-metallic inclusions in the welded joint
