Patriarchy is a dominating system that establishes male power in social relations as the social-ideological system and the structuring element of several ways of men‟s domination on gender social relations, on organization of social life, on private relations, and on political decision spaces. In this study we enlarge our reflection about patriarchy from the analysis of Forró lyrics, more specifically the variation known as stylized. Of late decades, it is a kind of music that has been receiving a large acceptance all over the national territory, making use of everyday expressions that propagate and make apology to many forms of discrimination, oppression and violence against women. We emphasize that over this study 14 Forró lyrics were analyzed of different styles besides stylized, like the traditional and the double meaning ones. However, we dwelled on the content analysis, particularly in three Stylized Forró lyrics, they are: Tapa na Cara (2008) by Saia Rodada Band; Mulher Roleira (2004), Aviões do Forró Band; and Bomba no Cabaré (2007), Matruz com Leite Band. In order to make a critical analysis of the elements in the lyrics content, we support ourselves on the theoretic-methodological references of the dialectical materialism, a method that allowed us to get closer to the totality of the reality that includes the popular involvement of the analyzed lyrics in a qualitative way. In that sense, we hold onto the theoretic-methodological categories: gender social relations, patriarchy, violence against women, ideology and cultural industry. As from the lyrics compilation, they were arranged by theme, we classified and analyzed the content, which allowed us to comprehend the messages in the lyrics, beyond the text shows at first sight. Today, there are many mechanisms of propagation and perpetuation of patriarchal ideology. A very relevant mechanism of this phenomenon is the sexual violence. The violence against women is a form to propagate and keep sexism, which may occur in different ways, like physical, psychological, sexual, patrimonial and social. Through our study we established that the propagation of the violence against women as being something natural and banal, giving reinforcement to the asymmetric construction of gender relations that priorizes male to the detriment of female. This banalization is perhaps, one of the strongest allies of this phenomenon‟s perpetuation, that affects women all over the world from different social classes

This work deals with the problematic of the determinations that contribute to become the adolescents involved with law. Thus, in this research, the social exclusion is apprehended as one of the most important determining to understand this problematic, once we defend that it is part of the trajectory of this adolescent's life since its birth as a punishment that starts before they becoming envolved in act's that break the law. It is still questioned the discussion of the reduction of the penal age, viewed aa a proposal that will contribute to perpetuate the repression. The objectives of the research were: analyze the problematic of adolescents in conflict with law, where social exclusion is seen here as a main category. The research also aims to understand the situation towards social exclusion and that this public is undertaken in the state of Rio Grande do Norte, more specifically in Natal. This is dane through analysis of the profile of adolescents that are submitted to the treatment at Centro Integrate de Atendimento ao Adolescente Acusado de Ato Infracional - CIAD in 2005. This is dane on arder to identify of the State's and society's actions towards this issue, how it has prevailed in analyzing if there is punishing or social protection. The research also contributed with discussion towards the non penal reduction of for underage minors. The approach realized if of qualiquantitative nature. The research was realized with 190 male adolescent subjects, age ranging from 12 to 21 that were interns at CIAD in the year of 2005. The research shows that their fundamental rights (education, health, amongst others) are disrespected on a daily basis by the State. The State prioritizes economic issues, making social inequality more profound. The main argument is that this problematic has its main oring in the social exclusion and it is imposed to the adolescents as a punishment before thes have been involved with the law going on top of the social protection. When the adolescent goes from being the victim to executioner, the Statute of Children and Adolescents is questioned by many sectors that defend the reduction of penal minority as a solution to reduce the country's violence. Thus, it was aimed here to discuss arguments that point to non exclusion, discrimination and repression. It is proposed that the State should assume children and adolescents as a priority, implementing what the statute establishes as well as assures related to the fruition of denied rights as a way to prevent their future involvement with violence

The World Trade Organization (WTO) was established in 1994 as a result of the Uruguay Round, and has as its principal aim advocate for the maintenance of free trade between nations. The preamble of its Constitutive Agreement specifically cites as an institution the goal of achieving sustainable development and the pursuit of protecting and preserving the environment, bringing into the sphere of world trade the idea that concern for the environmental cause is not restricted only the group of environmentalists, but rather has entered the economic landscape in a way not only ideological, but also pragmatic. The General Agreement on Tariffs and Trade (GATT) 1947, part of the GATT 1994, contains a device that allows the adoption of trade restrictive measures, provided that such measures aimed at protecting the environment - Article XX. The Settlement Body (DSB) is part of the WTO and acts in dissolving disputes between the countries motivated by trade. It examines two cases where countries have imposed restrictive trade measures with environmental justification. The first case was closed in 1996, with award of damages given to Brazil, on the breakdown of U.S. environmental legislation imposed on imported gasoline from Brazil - and the second, begun in 2005 and closed in 2007, coming out victorious again Brazil is on the import ban on retreaded tires to Brazil. The objective is to answer the question: how the environment is treated in the midst of trade discussions - which is aimed at its protection or its use with economic objectives in disguise? For the preparation of this work, extensive documentary research was undertaken with the virtual site of the WTO to review the entire production of legal cases and subsequent analysis of the key issue for the work, and literature of authors who have studied the tense relationship between trade international environment. The first case, it could be seen that the political movement performed by the U.S. with the aim of achieving acceptable standards of air quality was an institutional effort to ensure the quality of air, and thus would be inappropriate to say that the regulation of gasoline was merely a disguised trade barrier.However, a careful analysis of the implementation and operation of gasoline regulation may reveal intentions disguised trade and U.S. environmental argument did not hold. The weight of this environment was relegated, since there were clearly outside interests to the environmental cause. The second case, it was realized that, despite clear attempts by the EC to promote ecological dumping, send when brought to Brazil, supposedly a country with weaker environmental structure on surveillance, a residue that, pursuant to internal policies, as could not be sent to their own landfills, the Brazilian discourse remained focused on the environmental cause, and this sort there was the existence of disguised trade barriers, but of importance, at least a priori, the discussion of foreign forces on the environment environment because there is no way to legally justify the reversal of the total understanding of the first judging body, the sight of all the arguments presented by Brazil and the nonsubmission of new facts upon appeal. Still, quite heartening to reflect on the role of trade liberalization on the environment in general, because, while they do not reach a definitive conclusion will reveal positions in both directions, both for and against, the that only adds to the discussions and makes this a very fertile topic for future research

Hydrogeological prospecting in Northeast Brazil and in other crystalline terrains has been developed on the basis of structural and regional geology concepts that date back to the 50-60 decades and, as such, demand a natural re-evaluation and update. In this kind of terrain, the percolation and accumulation of ground water are controlled by fractures and other types of discontinuities, such as foliations and geological contacts that, through weathering, impart porosity and permeability to the rocks, allowing water flow and storage. Several factors should be considered in the process of locating water wells, as discussed in the literature. Among these, the kind of structures, fracture geometry (including aperture and connectivity) and their geological and chronological context. It is important to correlate fracture systems with the regional neotectonic framework. Fractures at low angle (sub parallel) with the principal stress axis (s1) are those which tend to open (actually they work as tension joints) and, in principle, would present major hydric potential; in the opposite side, fractures at high angle to s1 would behave as closed by a compressional component. Fractures diagonal to the compression and tension axes correspond to shear fractures and, due to their connectivity with second fractures, are also important in terms of hydric potential. Uplift followed by terrain denudation leads to decompression and a general tendency to open (aided by weathering processes) fractures and other rock discontinuities, at different orientations. Low angle fractures, formed in this context, are equally important to increase connectivity, collection of water and recharge of the aquifer systems. In a general way, an opening component (neotectonic or by terrain decompression) and several models to increase fracture connectivity correlate with a greater hydric potential of these structures. Together with parallel research, this thesis addresses models of ground water occurrence in crystalline terrains, either improving well established concepts like the (Riacho-Fenda model), but also stressing other possibilities, like the role of alluvium and paleo-regoliths (the Calha Elúvio-Aluvionar model) and of strongly altered, permo-porous zones placed at variable depths below the present surface, flanking several types of discontinuities, especially interconnected fracture arrays (the Bolsões de Intemperismo model). Different methodological approaches are also discussed in order to improve success rates in the location of water wells in crystalline terrains. In this methodological review, a number of case studies were selected in the eastern domain of the State of Rio Grande do Norte, involving the localities of Santa Cruz, Santo Antônio, Serrinha, Nova Cruz, Montanhas, Lagoa de Pedras and Lagoa Salgada. Besides the neotectonic analysis of brittle structures, this Thesis addresses the validation of remote sensing as a tool for ground water prospecting. Several techniques were tested in order to detect and select areas with higher potential for ground water accumulation, using Landsat 5-TM and RADARSAT images, besides conventional aerial photos. A number of filters were tested to emphasize lineaments in the images, improving their discrimination, to identify areas with higher overburden humidity, which could reflect subsurface water accumulation, as well as alluvium and other sedimentary covers that might act as recharge zones. The work started with a regional analysis with the orbital images, followed by analysis of aerial photos, up to a detailed structural study of rock exposures in the terrain. This last step involved the analysis of outcrops surrounding wells (in a ray of approximately 10 to 100 m) with distinct productivities, including dry examples. At the level required for detail, it was not possible to accomplish a statistical approach using the available well data catalogs, which lack the desired specific information. The methodology worked out in this Thesis must undergo a testing phase through location of new water wells. An increase in the success rates as desired will led to a further consolidation step with wider divulgation of the methodology to private companies and governmental agencies involved in ground water prospecting in crystalline terrains

This study focuses on the potential of several techniques used to identify depositional geometries and paleogeographical investigation on the SW border of the Potiguar Basin. Three areas were selected for an integrated geological, geophysical and geochemistry study. The main used techniques were facies analysis, remote sensing,ground penetrating radar (GPR) and gamma-ray in outcrops, as well as petrographic microscope observations and the using of scanning eletronic microscopic (SEM), and Carbon and Oxygen Isotopic study in the carbonate tufa. These methodological approaches were very efficient in the facies analysis of 2D geometries. The GPR profiles carried out in Quixeré identified important geological reflectors which allowed to the identification of depositional geometries of tufa. However, GPR profiles were not able to identify geological reflectors in the Apodi and Olho d´Água da Bica outcrops. Gammaray profiles also presented good results, which justify their use in 1D and 2D geometric analysis. Carbon and Oxygen Isotopic analyses were also used to investigate paleoenvironmental setting of tufa deposits. It is important to remark the excellent resultsof GRP using in the identification of deposition al geometries of tufa and their contact relationships with the underlying rocks. Field analysis of faults indicate a vertical sigma-1 orientation which was associated to normal faults

Seismic wave dispersion and attenuation studies have become an important tool for lithology and fluid discrimination in hydrocarbon reservoirs. The processes associated to attenuation are complex and are encapsulated in a single quantitative description called quality factor (Q). The present dissertation has the objective of comparing different approaches of Q determination and is divided in two parts. Firstly, we made performance and robustness tests of three different approaches for Q determination in the frequency domain. They are: peak shift, centroid shift and spectral ratio. All these tests were performed in a three-layered model. In the suite of tests performed here, we varied the thickness, Q and inclination of the layers for propagation pulses with central frequency of 30, 40 and 60 Hz. We found that the centroid shift method is produces robust results for the entire suíte of tests. Secondly, we inverted for Q values using the peak and centroid shift methods using an sequential grid search algorithm. In this case, centroid shift method also produced more robust results than the peak shift method, despite being of slower convergence
