Passivo ambiental e o setor de exploração de petróleo em terra: abordagem teórica e percepção institucional dos impactos ambientais gerados na atividade

The search for a sustainable development is result of the exhaustion of the natural resources of the planet that demands globalizated politics with practical of compatible economic development with the protection of the quality of life for the future generations. This work presents a study on the thematic on the environmental liabilities in the organizations with focus in the industry of the oil and the production of oil in land in the state of Rio Grande do Norte. Some types of environmental liabilities are presented, as well as, some estimates techniques. Moreover, this work presents surveys of some variable that stimulate the organizations to implant technologies of reduction of the impacts in the environment as: the environmental legislation, costs, the main impacts of the production of oil in land. On the basis of the bibliographical research and in the identified variable, it was carried a case study with state and municipal technician that act in the sectors of fiscalization (IBAMA-RN and IDEMA-RN) with the objective to deepen the discussion regarding the impacts of the industry of the oil, the effectiveness of the current law, the performance of the institutions the federal level and how to prevent impacts in the environment. It was observed that the environmental liabilities are a little spread subject in the organizations, perhaps to be unknown and of few theoretical referencees at the national level, regarding to the evaluation techniques. At the same time, absentee in the national politics that conducts the oil exploration

Efeito da inclinação do plano de terra para antenas de microfita multicamadas com elementos parasitas fractais

This work presents the analysis of an antenna of fractal microstrip of Koch with dielectric multilayers and inclinations in the ground plane, whose values of the angles are zero degree (without inclinations), three, seven and twelve degrees. This antenna consists of three dielectric layers arranged vertically on each other, using feeding microstrip line in patch 1, of the first layer, which will feed the remaining patches of the upper layers by electromagnetic coupling. The objective of this work is to analyze the effects caused by increase of the angle of inclination of the ground plane in some antenna parameters such as return loss, resonant frequency, bandwidth and radiation pattern. The presented results demonstrate that with the increase of the inclination angle it is possible to get antennas with characteristics multiband, with bigger bandwidth, and improving the impedance matching for each case analyzed, especially the larger angle

Olhar em terra de cego: a visualidade em Ensaio sobre a Cegueira

"Looking at earth from blind: travel in the visuality of the test on Blindness" is a literary Essay resulted from the experience of different points of view regarding the Essay on Blindness (1996), not only showing a Modern aesthetical tendency in dialog with the Baroque one, but also discussing subjects related to the History of Mentalities. The chapters are disposed as follows: The first one presents a short Excursus about the author and his work; the second one introduces the concept of Allegory exemplifying it with representative images of Romance; the third one presents tragic elements in dialog with the Bataille Eroticism in an Allegory of Feeling; the fourth one shows Stylistic Features used as a display mean of Comedy in Romance going towards the musicalness, being the features used to provoke laugh; the fifth and last one discusses about the study pertinence. To conclude, in favor of a Sight Education, the study considered authors such as: Ariès (1977), Bataille (2003), Bakhtin (2002, 2000, 1999), Benjamin (2000, 1996), Chauí (2005, 2000), Foucault (2006, 2005, 2004, 2002), Freud (1970), Hansen (2006), Lino (2004), Sartre (2005), Vovelle (1996)

Terra Natal, de Ferreira Itajubá, e a permanência do romantismo

In this dissertation we argue that the work Terra Natal, by the poet Ferreira Itajubá, presents, predominantly, themes and forms typical of the Romantic period, although it came out in 1914, when the romantic aesthetic was no longer popular in Brazilian Literature. Firstly, we discuss about Ferreira Itajubá s biography, his bibliographic production as well as the critical fortune of his works. Secondly, we outline the course of the Romantic Movement from its emergence in Europe to its arrival in Brazil as well as its impact in the state of Rio Grande do Norte. Finally, we analyze of Terra Natal, taking into account other aspects such as context and structure through the analysis of the poems VII, IX, XVIII, XXI and also of the song Viola , inserted in the poem VIII. We highlight the following romantic themes during the analysis: exile, nostalgia for the past, cult of native land, the romantic view of woman, projection of soul s state on nature, and religiosity. We will try to create dialogues between Terra Natal and works of popular Romantic Brazilian writers, such as Gonçalves Dias, Casimiro de Abreu, José de Alencar,Visconde de Taunay and Castro Alves, in order to show the affiliation of the above-referenced work and the Romantic ideals

A invenção da Terra da Luz: história, literatura e paisagem (1875-1914)

Ce travail est un étude de cas qui analyse la construction litéraire du paysage du « Sertão» du Ceará entre la fin du siècle XIX et le début du siècle XX. Pour cela, quelques oeuvre simbole de la production litéraire du Ceará ont été sélectionnés, comme les textes qui suivent: O sertanejo (1875), de José Martiniano de Alencar; Os retirantes (1879), de José Carlos do Patrocínio; A fome (1890), de Rodolfo Marcos Teófilo; Luzia-Homem (1903), de Domingos Olímpio Braga Cavalcanti; Terra de sol: natureza e costumes do Norte (1912), de Gustavo Dodt Barroso et finalement, Aves de arribação (1914), de Antônio Sales. Ces oeuvres non seulement prend la nature comme personage, elles représentent aussi trois moments de la production litéraire du Ceará : romantique, réaliste et naturaliste. A invenção da Terra da Luz se rapporte à l idée d une littérature qui fait remarquer le paysage diurne du Sertão du Ceará, élaborée par ces hommes des lettres dans ses discours formidables, beaux et des matériaux qui viennent de ses rapports avec le monde naturel. Pour réaliser une tel entreprise, les idées de Edmund Burke et Gaston Bachelard se sont constitués en référence de cet étude. Et cette réflexion sur la description, la rêverie et l imagination marchent côte-à-côte au discours de ces littéreurs qui ont construits un espace simbolique spécifique : le sertão du Ceará. Comme ça, quelques thèmes deviennent canonique à la forme de penser, représenter et imaginer l espace du sertão du Ceará. De cette manière, le paysage est beaucoup plus que la contemplation, une fois qu elle est liée aussi à la rêverie poétique, à la mémoire et l imagination. C est de là l invention du paysage, car ces littéreurs n ont pas l accès au paysage purement naturel parce que ses perceptions et sensibilitées sur le monde du sertão ont été historiquement, c est-à-dire, dans un certain temps et espace

Ocidentalização, territórios e populações indígenas no sertão da Capitania do Rio Grande

The objective of this work is to understand some of the modifications caused for the phenomenon of the westernization in the hinterland of the Capitania do Rio Grande e in the life of the indians populations that inhabited there during the Colonial Period. We break of the quarrel of Serge Gruzinski concerning the westernization, understood while immersed phenomenon in the context of the expansion of the commercial capitalism and that, for the imposition of the culture occidental person to the alteridades of the New World, emprende the conquest of its territories, bodies and souls. The space clipping has covered the hinterland of the Capitania do Rio Grande, specifically the colonial territory of the Freguesia da Gloriosa Senhora Santa Ana do Seridó. The chosen chronological limit for the research corresponds to the Colonial Period and part of the Imperial one. However, the emphasis falls again on the period that it initiates in 1670, year of the oldest concession of would sesmaria known until the moment in the hinterland of the Rio Grande, extending itself until the decade of 1840. Sources of written by hand nature, cartographic printed and compose the used document roll: official correspondence and legislation, petitions of would sesmaria, inventories post-mortem, justifications of debt, registers of parish, maps, action civil court jurisdiction, notes of notary's office, land landmarks. We take the method, analyzed for Carlo Ginzburg, to cross these sources between itself and to detect its implied particularitities and ideas in the space between lineses, but, attributing it status to they of a colonial speech, fruit of the bureaucracy of where it was originated and of the social place of who produced it. We look for to demonstrate, throughout the work, that the phenomenon of the westernization desestruturou the aboriginal societies and its habitat, constructing, over its rubbles, a colonial territory that found in the cartography of the Freguesia de Santa Ana an efficient instrument of control of the space and the population. On the other hand, if the imposition of the culture occidental person exterminou great part of the native population that inhabited the hinterland of the Rio Grande, the remainders of these indians and the mestizos of descending them had survived in diverse ways in the freguesia: in the condition of captives of war or in regimen of servile work, as living or assistants in the farms, populations and village; rambling without route in the fields and the population spots; as mediating agents between the world occidental person and the native, exerting military or civil positions and still appealing to Justice in search of its rights of inheritance. Experiences of slavery, servitude, errância and mediation, but, also of resistance, adaptation, mestization in the Freguesia de Santa Ana

Estratégia reprodutiva do peixe-voador, Hirundichthys affinis e do peixe agulha preta, Hemiramphus brasiliensis no litoral de Caiçara do Norte, Rio Grande do Norte, Brasil

The flyingfish, Hirundichthys affinis (Günther, 1866) (Exocoetidae) and ballyhoo half beak, Hemiramphus brasiliensis (Linnaeus, 1758) (Hemiramphidae) are marine fish species of commercial value, which contribute to artisanal fishery production of Rio Grande do Norte, Brazil. Besides the economic importance, these fish are important from an ecological point of view, being components in pelagic food chain, where they are the preferred prey of larger predators of high commercial value. This study aimed to determine the reproductive strategies of H. affinis and H. brasiliensis and the fishery production of H. affinis in the northern coast of Rio Grande do Norte. The results are presented in the form of six cientific articles and a review paper. The first article presents the morphometric measurements and meristic counts which confirmed the taxonomic status, population structure in length-weight and the gonad development of H. affinis through macroscopic observations of the ovaries and testes. Females of this species were bigger and heavier than males. The second article describes the reproductive tactics, such as, sex ratio, length at first sexual maturity, histological aspects of gonads, fecundity and spawning season, that indicate the reproductive strategy of H. affinis. The third article shows annual changes in the fishery production of H. affinis in Caiçara do Norte, during the period of 1993 to 2010, emphasizing the relevance of this fish in total fishery production of Rio Grande do Norte, besides registering the fall in production in the years 2008 to 2010. The fourth article describes the population structure, with respect to the length and weight, the length-weight relationship, growth type and sex ratio of Hemiramphus brasiliensis. The fifth article describes the reproductive biology of H. brasiliensis, with details about sex ratio, length at first sexual maturity, fecundity, type of breeding and spawning season. The sixth article deals with the reproductive strategy of H. brasiliensis. The review paper presents the topic of age determination of tropical fish using analysis of otoliths. Both species use the coastal waters of Caiçara do Norte for reproductive purposes. The flying fish, H. affinis migrates from the oceanic waters to the coastal waters to reproduce, coinciding with the rainy season. H. affinis presents total spawning and a seasonal reproductive strategy. However, H. brasiliensis lives and reproduces in the coastal waters displaying partial spawning and an equilibrium reproductive strategy

A inserção das mulheres na luta pela terra: movimento de participação e/ou submissão

The following dissertation studies the insertion of peasant women in the conflict for land since the occupation process, dispossession and construction of the settlement New Horizon II, in the municipal district of Maxaranguape. It analyses their participation in the conflict Valley of the Hope", that resulted in the settlements New Life II and New Horizon II in the municipal district of Maxaranguape. The analysis exposes the reasons which took the peasant women, after the land conquest, to go back into domestic space and/or to assume positions of lesser relevance in the political organizations of the settlement. In the conflict Valley of the Hope, the women had a fundamental role, facing the police violence, being front line of the conflicts against the repression forces, risking their lives and the life of their families. After the conquest of the land, transformed into the New Horizon II Settlement, there are a lot of changes in the participation of the women. We can observe that, despite the protagonism of the families, in special of the women in the Valley of the Hope conflict, these female workers still experiment unequal social, economic, political and cultural conditions in relation to the men, expressing the gender inequalities which are found in the daily life of the settlement: in the community, in the domestic and agricultural task. The conflict for the land in the Valley of the Hope and the conquest of the settlement did not necessarily mean the incorporation of the emancipation of the peasant women. However, the political participation in the development of the conflicts allowed to the women the self discovering and the beginning of an emancipation process as gender. There are signals of continuities and ruptures of the present culture, almost always stimulated by the organization of the agricultural female workers

Geração automática de testes a partir de descrições de linguagens

Some programs may have their entry data specified by formalized context-free grammars. This formalization facilitates the use of tools in the systematization and the rise of the quality of their test process. This category of programs, compilers have been the first to use this kind of tool for the automation of their tests. In this work we present an approach for definition of tests from the formal description of the entries of the program. The generation of the sentences is performed by taking into account syntactic aspects defined by the specification of the entries, the grammar. For optimization, their coverage criteria are used to limit the quantity of tests without diminishing their quality. Our approach uses these criteria to drive generation to produce sentences that satisfy a specific coverage criterion. The approach presented is based on the use of Lua language, relying heavily on its resources of coroutines and dynamic construction of functions. With these resources, we propose a simple and compact implementation that can be optimized and controlled in different ways, in order to seek satisfaction the different implemented coverage criteria. To make the use of our tool simpler, the EBNF notation for the specification of the entries was adopted. Its parser was specified in the tool Meta-Environment for rapid prototyping

Geração de casos de teste a partir de especificações B

With the increasing complexity of software systems, there is also an increased concern about its faults. These faults can cause financial losses and even loss of life. Therefore, we propose in this paper the minimization of faults in software by using formally specified tests. The combination of testing and formal specifications is gaining strength in searches mainly through the MBT (Model-Based Testing). The development of software from formal specifications, when the whole process of refinement is done rigorously, ensures that what is specified in the application will be implemented. Thus, the implementation generated from these specifications would accurately depict what was specified. But not always the specification is refined to the level of implementation and code generation, and in these cases the tests generated from the specification tend to find fault. Additionally, the generation of so-called "invalid tests", ie tests that exercise the application scenarios that were not addressed in the specification, complements more significantly the formal development process. Therefore, this paper proposes a method for generating tests from B formal specifications. This method was structured in pseudo-code. The method is based on the systematization of the techniques of black box testing of boundary value analysis, equivalence partitioning, as well as the technique of orthogonal pairs. The method was applied to a B specification and B test machines that generate test cases independent of implementation language were generated. Aiming to validate the method, test cases were transformed manually in JUnit test cases and the application, created from the B specification and developed in Java, was tested. Faults were found with the execution of the JUnit test cases

Entre índios tremembé e trabalhadores rurais: historicidade, mobilização política e identidades plurais no Ceará

As pesquisas antropológicas brasileiras podem tratar de forma frequentemente estanque e separada, por um lado, grupos camponeses e, por outro lado, grupos étnicos, quais sejam, ‘índios’, ‘quilombolas’, etc. Contextos e situações que indicam pluralidade identitária costumam ser simplificados em sua caracterização etnográfica e da dimensão multifacetada de relações e redes sociais. Assim, discuto aqui os processos de mobilização étnico-política e de demanda territorial, sem perder de vista os processos de ressignificação cultural e construção identitária que se engendram a partir de um campo semântico da etnicidade. Abordo, então, certas situações étnicas Tremembé (estado do Ceará) que desestabilizam, embaralham e colocam em risco representações antropológicas sobre o ‘camponês’, o ‘regional’ e o ‘indígena

Um estudo das condições de percolação e estabilidade em barragens de terra mediante métodos geofísicos: caso do dique de Sant Llorenç de Montgai - Espanha

The monitoring of Earth dam makes use of visual inspection and instrumentation to identify and characterize the deterioration that compromises the security of earth dams and associated structures. The visual inspection is subjective and can lead to misinterpretation or omission of important information and, some problems are detected too late. The instrumentation are efficient but certain technical or operational issues can cause restrictions. Thereby, visual inspections and instrumentation can lead to a lack of information. Geophysics offers consolidated, low-cost methods that are non-invasive, non-destructive and low cost. They have a strong potential and can be used assisting instrumentation. In the case that a visual inspection and strumentation does not provide all the necessary information, geophysical methods would provide more complete and relevant information. In order to test these theories, geophysical acquisitions were performed using Georadar (GPR), Electric resistivity, Seismic refraction, and Refraction Microtremor (ReMi) on the dike of the dam in Sant Llorenç de Montgai, located in the province of Lleida, 145 km from Barcelona, Catalonia. The results confirmed that the geophysical methods used each responded satisfactorily to the conditions of the earth dike, the anomalies present and the geological features found, such as alluvium and carbonate and evaporite rocks. It has also been confirmed that these methods, when used in an integrated manner, are able to reduce the ambiguities in individual interpretations. They facilitate improved imaging of the interior dikes and of major geological features, thus inspecting the massif and its foundation. Consequently, the results obtained in this study demonstrated that these geophysical methods are sufficiently effective for inspecting earth dams and they are an important tool in the instrumentation and visual inspection of the security of the dams

Reforma agrária de mercado e territorialização: um estudo a partir do Programa Cédula da Terra em Canindé-CE

The research Reforma Agrária de Mercado e Territorialização: um estudo a partir do Programa Cédula da Terra em Canindé-Ce , has an objective to discuss until whas time denominated agrarium refom has capacity of territory the of families in Five from the seven settlements cmated by resourles from the prgramme cell of earth em Canindé-Ce. In this context, the present work analysis the relation sitip between power and kind of identity, in special in those settlements, trying to learn the dialetic relationship. That passes by the process and appropriation in these spaces by these families gave the beginning of buying the land. The procedure methologic used by us gave privilege to realize the interview included in this process, wita the leaders of rural associations (STR); commission clero of earth (CPT); rural workers movement without land (MST); wita agricolas tecnics, and so the local coordinators of cell of earth in Fortaleza. The analysis of agrarium reform in Canindé, infects that the families giving entrance in buying the land, they could creatieg a hope in quality of life for getting the land. Nevertheless, it did not happen, in the rost of the parts of the areas in study. The territories present in general focus, the worse process of poomest besides the amount of debiths of these families, putting in risk the territorialization of themselves
