Descreve-se neste trabalho o período pré-Petrobras (1858 a 1953 e a exclusividade da Petrobras (1954 a 1997 que resultou no expressivo volume de reservas de petróleo no país, da ordem de 17 bilhões de barris de óleo equivalente no final de 1997. Projetos de produção já iniciados elevarão a produção a mais de 1,5 milhão de barris de óleo por dia no início do novo século. O gás natural crescerá rapidamente sua participação na matriz energética a partir de 1999. Com a instalação da Agência Nacional de Petróleo (ANP inicia-se uma nova fase, sendo esta responsável pela atração de novos investimentos na busca de novas reservas nas bacias sedimentares brasileiras, cujo potencial é ainda significativo. Diversas empresas internacionais deverão estar operando no país no curto prazo, inicialmente associadas à Petrobras. O modelo adotado para as atividades de exploração e produção no país é o de concessão. A atividade no Brasil nesta área dependerá do regime fiscal que vier a ser implantado.THE APPROVAL OF the new Petroleum Law in 1997 proposed a dramatic change in the activities of petroleum exploration in Brazil after almost fifty years of its initial entrepreneurual organization, represented by the creation of Petrobras, in 1953. In this work two important periods are described: the pre-Petrobras period (1858 to 1953 and the period when Petrobras acted alone in the oil business (1954 to 1997. During the last one, significant results were achieved. The amount of reserves reached 17 billion barrels of oil equivalent and were made available to the country at the end of 1997. Production projects already in place or under development will raise Brazilian daily production to levels of 1.5 million barrels of oil per day

  8. 150 years of Rudolf Diesel; 150 Jahre Rudolf Diesel

    Energy Technology Data Exchange (ETDEWEB)

    Basshuysen, R. van; Siebenpfeiffer, W. (eds.)

    2008-03-15

    'My engine is still making great progress', Rudolf Diesel wrote in a letter to his wife on 3 July 1895. The fact that Diesel's statement still holds true can be seen every day on our roads and at sea. But it is equally true that the idea of this eccentric and doubter who wanted to dedicate himself with an over-inflated self-belief to the welfare of humanity, needed a certain time to take a form that others could recognise in order to continuously refine this life's work. Diesel himself did not live to see most of the milestones that were repeatedly set thanks to his engine. It was not until 23 years after his unexplained death in 1913 that people were able to buy the first passenger car to be equipped with a diesel engine - with a top speed of 90 km/h. Today, diesel cars can easily reach speeds of up to 300 km/h, and even if there is little point in such excessive speeds outside racetracks like Le Mans, they are nevertheless clear evidence of the incredible evolution of the noisy, smoky truck engine to a high-tech racing power unit, from the ear-splitting rattle of the pre-chamber diesel to the highly refined, soot-free, common-rail diesel engine of today. The Publisher hopes you enjoy reading this unique progress report. (orig.)

  12. Rudolf Steiner as a religious authority

    Directory of Open Access Journals (Sweden)

    Tore Ahlbäck

    2008-01-01

    Full Text Available The aim of this article is to clarify what Rudolf Steiner’s followers thought of him at the time of his demise. How can we explain the rapid spread of the Anthroposophical Society in Europe and the United States during the inter-war period? Can it be explained by referring to Rudolf Steiner’s own authority? What kind of authority did he possess? Did the members of the Anthroposophical Society regard him as a divine being, a prophet, or an ordinary religious teacher? The material for this article consists of a selection of the obitu­aries published in the anthroposophical press after Rudolf Steiner’s death on 30 March 1925. Needless to say, obituaries are usually tendentious, and therefore controversial as source material. For the purpose of the present article, however, this kind of material is suitable, since the aim here is to study the tendency itself. The restraint that followers might be assumed to practice in publishing their opinion on Steiner in commonly available writings is minimised in the type of material chosen here. The primary interest is to find out whether his followers portray Steiner as a human being, or as a divine, or semi-divine being.

    Rudolf Böck, a distinguished scientist who worked at CERN for over 40 years, died unexpectedly on 15 April at the age of 80.   Rudy obtained his PhD in Munich and started work at CERN on 5 October 1959, just a few years after its establishment, as a mathematician in the Data Handling Division. He worked on a series of experiments including WA7, UA1, and JETSET at LEAR, as well as leading the RD11 (EAST) project studying second-level triggering for the LHC experiments, before joining ATLAS.   As a member of the ATLAS TDAQ team, Rudy was deeply engaged in second-level trigger activities – from the physics requirements and architectural design to studies with early prototypes. He retired from CERN in 2000, ending his activity on ATLAS, but joined the MAGIC experiment in La Palma as a member of the MPI Munich group, splitting his time between Munich and Geneva. Rudy will be remembered as a charming, kind and generous man, always interested and ready to share his wisd...

    Full Text Available A exploração do petróleo se constitui num elemento significativo para a economia sergipana. A contradição existente entre o subsolo rico e a população pobre levanta indagações a respeito da gestão destes recursos e as condições de vida da população. Tais condições, aliadas à entrada de novos atores na exploração do petróleo em Sergipe e à gestão dos recursos advindos da exploração, vêm incutindo relações peculiares à política neoliberal na região e em Sergipe. O estudo foi desenvolvido a partir da análise e cruzamento de informações disponíveis na Agência Nacional do Petróleo (ANP, Instituto Brasileiro de Geografia e Estatística (IBGE, Tribunal de Contas da União (TCU e PETROBRAS, dentre outros setores. A carência de políticas sociais que ofereçam às populações condições de inserção nas questões política, econômica e social da região produtora de petróleo tem impedido o desenvolvimento efetivo e mudança no padrão de vida das populações, evidenciando a incoerência entre os altos valores depositados nos cofres públicos municipais decorrentes dos royalties e os elevados índices de pobreza apresentados na região. Tal constatação reforça a ideia de que as políticas públicas devem primar pela redução da desigualdade a partir da gestão responsável dos recursos públicos. Abstract OIL, ROYALTIES AND POVERTY The exploitation of oil has significant element for the Sergipe´s economy.

    The “Rudolf Mössbauer Story” recounts the history of the discovery of the “Mössbauer Effect” in 1958 by Rudolf Mössbauer as a graduate student of Heinz Maier-Leibnitz for which he received the Nobel Prize in 1961 when he was 32 years old. The development of numerous applications of the Mössbauer Effect in many fields of sciences , such as physics, chemistry, biology and medicine is reviewed by experts who contributed to this wide spread research. In 1978 Mössbauer focused his research interest on a new field “Neutrino Oscillations” and later on the study of the properties of the neutrinos emitted by the sun.

    Full Text Available The article explores the educational value that Ellen Key (1849-1926, Rudolf Steiner (1861-1925 and Maria Montessori (1870-1952 attributed to children's stories. In the late nineteenth and early twentieth century these three important authors contributed to the renewal of the educational theories and practices. They dedicated a part of their pedagogical reflections to the educational meanings of children's stories; consider, e.g., the many pages of Ellen Key on children's literature, the recommendations of Rudolf Steiner on the educational relevance of fairy tales and mythology or, finally, Maria Montessori's reflections on fairy tales. The article examines these ideas from a historical and pedagogical point of view.

    Full Text Available In the last years there were several publications about Rudolf Virchow and the cellular pathology in the former Soviet Union. The authors, who know so much about Virchow, can be informed where his library is. The Virchow’s library, comprising 12,689 volumes, was united in 1909 with the library of Berlin Medical Society. In 1944 the Library was transferred to the castle Boitzenburg (land Brandenburg, and from there, according to some witnesses, it was taken away by Soviet military trucks. Probably, the Library was brought to Moscow, in one of the institutions of the Russian Academy of Medical Sciences (RAMN. In the RAMN library, several editions are catalogued, which could have originated from the library of the Berlin Medical Society. Some of these catalogued books are not given out to the readers. In the Central Medical Library in Moscow there are books from 19th century with German library stamps. In conclusion, one of the motives of abundant publication about Virchow and the cellular pathology is popularization of the concept of cellular pathology in connection with stem cells and the cell therapy, which has become widespread in Russia.

    Rudolf Nissen (1896-1981) was a surgeon whose career began in Germany during the first third of the 20th century, a period of rapid progress in biomedical technology, during which neurosurgery, anesthesiology, and other specialties emerged. A protégé and later close colleague of thoracic surgery pioneer Ferdinand Sauerbruch (1875-1951), Nissen resigned from the Berlin Charité Clinic and left Germany in 1933, in response to the rise of Nazi fascism. Throughout his subsequent career in Istanbul, Turkey, the American cities of Boston and New York, and finally Basel, Switzerland, Nissen developed innovative surgical techniques, advocated for patient-centered medical education, and promoted surgical subspecialization. A lifelong proponent of clear scientific writing, Nissen expressed, in extensively published work, his philosophy that progress in surgery depends critically on rigorously applying the scientific method, upholding professional integrity, and respecting human dignity.

  18. [The Base of the Skull. Rudolf Virchow between Pathology and Anthropology].

    Science.gov (United States)

    Seemann, Sophie

    2016-01-01

    Throughout his scientific career, the pathologist and anthropologist Rudolf Virchow (1821-1902) examined countless skulls, gradually changing his perspective on this object of research. Initially, he was mainly concerned with pathologically deformed skulls. From the 1850s onwards, he gradually developed a more anthropological approach, and anthropology increasingly came to dominate his scientific interest. This article shows how different influences became central for the establishment of his specific and dynamic model of the human skull development and its successful application in anthropology. Crucial for this process were Virchow's collaboration with his teacher Robert Froriep (1804-1861) in the department of pathology of the Charité, his research on cretinism and rickets, as well as his description of the base of the skull as the center of skull development. His research work was attended by and showed a reciprocal interaction with the buildup of large skull collections. This article uses Virchow's original publications on skull pathology as well as his still preserved skull specimens from the collection of the Berlin Museum of Medical History at the Charité for an integrated text and object based analysis.

    The British National Health Service (NHS) is undergoing possibly the most far-reaching set of changes in its sixty-five-year history. While some commentators (like Rudolf Klein) insist that little of substance is likely to change, others consider that the politics of reform may prove quite different on this occasion. The coalition government is committed to restructuring the welfare state and public services and to rolling back the state. The NHS as a popular monopoly public service runs counter to its neoliberal ideology. While (for now) remaining committed to a publicly funded system of health care that is largely free at point of use, the government wishes to encourage much greater diversity in the provision of care, including a much larger role for the for-profit private sector. Despite significant opposition to its proposals, few concessions have been forthcoming, and the legislation that passed onto the statute book in March 2012 remained essentially unchanged. Notwithstanding the lack of convincing evidence, the government is wedded to encouraging greater competition and choice. Thosewho believe the changes will amount to far less than its architects hope for are being too complacent and overlooking the strength of the government's ideological convictions. These threaten to dismantle the NHS and replace it with a more costly, fragmented, and less effective system of care that is driven by profit in place of the public interest.

    Full Text Available Rudolf Bultmann was one of the leading thinkers within an influential theological direction that arose in Europe after the First World War, known as dialectical theology. Comprehensive introductions to the life and work of Bultmann in the South African theological journals, written in Afrikaans, either does not exist, or are difficult to trace for the Afrikaans readership. This article on Bultmann aims to fill the gap by offering a lexicographical contribution on the life and work of Bultmann. The focus of this article is on Bultmann as a Lutheran thinker. The theme of the New Testament and systematic theology is essentially the same, namely to explain the concept of Christian self-understanding as an eschatological event in which faith is expressed for the sake of faith in God and only in God. Bultmann explained the same theological concepts with his theology as those that were explained by the church reformers of the 16th century, but under radically new circumstances. The so-called modern and postmodern people of our time not only broke ties with the past, but in the process they also lost their ability for using historical-critical patterns of thought that tries to bridge historical distances, and therefore sacrificed all efforts to think systematically on the altar of relativism. We can learn from Bultmann what systematic reformed theology really is.

  3. Rudolf Virchow's medical school dissertation on rheumatism and the cornea: overlooked tribute to the cornea in biomedical research.

    Margo, Curtis E; Harman, Lynn E

    2015-02-01

    To critique Rudolf Virchow's medical school dissertation on rheumatism and the cornea and to determine whether it might have anticipated his remarkable career in medicine. Review of the English translation of Rudolf Virchow's de Rheumate Praesertim Corneae written in 1843. The dissertation was more than 7000 words long. Virchow considered rheumatism as an irritant disorder not induced by acid as traditionally thought but by albumin. He concluded that inflammation was secondary to a primary irritant and that the "seat" of rheumatism was "gelatinous" (connective) tissues, which included the cornea. He divided kerato-rheumatism into different varieties. The prognosis of keratitis was variable, and would eventually lapse into "scrofulosis, syphilis, or arthritis of the cornea." Virchow's dissertation characterizes rheumatism in terms of chemical and tissue interactions that make little sense in the context of today's knowledge of rheumatic disease and keratitis. Ironically, many of these concepts were made obsolete by the cellular model of disease that Virchow championed. Virchow decided to pursue the study of rheumatism through the cornea because he thought that the cornea was an ideal tissue to study disease. This discernment was passed on to his students whose seminal contributions to general pathology were based on research with the cornea. It is debatable whether Virchow's insight into the importance of the cornea in biomedical research at such an early stage of his career could have predicted his monumental contributions to medicine.

  9. The Numinous, the Ethical, and the Body. Rudolf Otto’s “The Idea of the Holy” Revisited

    Directory of Open Access Journals (Sweden)

    Nörenberg Henning

    2017-10-01

    Full Text Available In this paper, I investigate the non-rational, affective dimension of religious experience that Rudolf Otto attempted to address with his notion of the numinous. I argue that this notion is best understood in terms of an atmospheric quality impacting on the subject’s feeling body. Therefore, I draw on discussions in phenomenology and pragmatism, despite the fact that Otto’s own epistemological framework is rooted in a different tradition. Drawing on those discussions helps defend some of Otto’s claims about the relation between the non-rational, affective dimension and reason against the prevalent accusation of unscientific mysticism. I then illustrate the yet unexhausted potential of these very claims by arguing that the numinous in Otto’s sense plays an irreducible role in the ethical reflections of such distinct authors as Kant and Levinas.

  10. [Sigmund Freud, Rudolf Meringer and Carl Mayer: slips of the tongue and mis-readings. The history of a controversy].

    Science.gov (United States)

    Hinterhuber, Hartmann

    2007-01-01

    In both his The Psychopathology of Everyday Life and his Lectures Sigmund Freud derived the terms unconscious, preconscious and conscious, particularly from slips in speech, slips in reading and forgetfulness. In these slips, Freud recognised parallels to dreams. In the work mentioned, he analysed these in depth as part of mental motivation. In the papers referred to, Sigmund Freud paid tribute to Rudolf Meringer and Carl Mayer's study which was published in 1895. Meringer and Mayer showed as phenomena reversals and rearrangement of whole words, syllables or sounds, along with pre-tones or anticipations and echoes, word contaminations and word substitutions as responsible for slips of the tongue. The present work demonstrates how passionately these three scientists have contributed to the controversy of their standpoints. For modern psycholinguistics and the psychology of language, speech errors are always an expression of a momentary malfunction of the human speech production system: for the cognitive process of speech production slips of the tongue offer an insight into speech processing. Pre-tones and echoes, serialization errors, as Meringer and Mayer recognised, represent the vast majority of slips of the tongue. They do not reveal any hidden point. But with lexical-semantic slips of the tongue the question of mental motivation is admissible. This short paper is a sign of appreciation and gratitude: firstly, a modest birthday gift for Sigmund Freud, secondly homage to Carl Mayer, who influenced generations of neurologists in his 40 years of chairing the Psychiatric-Neurological Clinic in Innsbruck, so that Hans Ganner rightly spoke of a "Carl Mayer School". But lastly, this short study is also-and especially-a late recognition of Rudolf Meringer, the great Austrian linguist. The view an individual has concerning mental processes and the "topology of the psychic apparatus" is decisive as to the power of determination attached to the unconscious.

    2011-07-01

    Full Text Available Rudolf Steiner presented his Agriculture Course to a group of 111, farmers and others, at Koberwitz (Kobierzyce, Poland in 1924. Steiner spoke of an agriculture to ‘heal the earth’ and he laid the philosophical and practical underpinnings for such a differentiated agriculture. Biodynamic agriculture is now practiced internationally as a specialist form of organic agriculture. The path from proposal to experimentation, to formalization, to implementation and promulgation played out over a decade and a half following the Course and in the absence of its progenitor. Archival material pertaining to the dissemination of the early printed editions of ‘The Agriculture Course’ reveals that within six years of the Course there was a team of more than 400 individuals of the Agricultural Experimental Circle (AEC, each signed a confidentiality agreement, and located throughout continental Europe, and also in Australia, Britain, Canada, New Zealand, South Africa, and USA. Membership expanded to over 1000 AEC members (with a lower bound estimate of 1144 members who were committed to working collectively towards an evidence based, new and alternative agriculture, ‘for all farmers’, which was to be developed into a ‘suitable for publication’ form. That publication milestone was realized in 1938 with the release of Ehrenfried Pfeiffer’s ‘Bio-Dynamic Farming and Gardening’ which was published simultaneously in at least five languages: Dutch, English, French, German and Italian

    Full Text Available OBJETIVO: A exposição ocupacional típica de uma refinaria de petróleo pode alterar a função hepática de seus trabalhadores. Assim, o objetivo do estudo foi identificar fatores de risco de alterações em enzimas hepáticas em trabalhadores de uma refinaria de petróleo. MÉTODOS: Os trabalhadores de uma refinaria de petróleo, localizada em São Francisco do Conde, Estado da Bahia, eram submetidos a exames periódicos anuais de 1982 a1998. O estudo caso-controle investigou todos os 150 casos de indivíduos com alteração simultânea de gama-glutamil transferase e de alanino amino transferase, de pelo menos 10% acima do valor de referência. Como controles, foram selecionados 150 indivíduos sem quaisquer alterações de enzimas hepáticas ou de bilirrubinas, desde a sua admissão. Foram calculadas as razões de chance e respectivos intervalos de confiança de 95% a partir de modelos de regressão logística. RESULTADOS: Em todos os setores de produção, o risco de alteração de enzimas hepáticas foi significantemente mais elevado do que no setor administrativo (RC=5,7; IC 95%: 1,7-18,4, estando controlados os efeitos do álcool, obesidade e antecedentes médicos de hepatite. No período 1992-1994 foram registrados 89 casos, 88 deles provieram dos diversos setores da produção. CONCLUSÕES: A exposição ocupacional desempenha papel importante na determinação de alterações de enzimas hepáticas em trabalhadores do refino de petróleo, além dos fatores de risco eminentemente biológicos e/ou comportamentais como obesidade e o consumo de álcool.

    Full Text Available O artigo se propõe a analisar a problemática do petróleo e as suas múltiplas implicações para a governança global contemporânea. O petróleo é mais o estratégico insumo energético do planeta, capaz de levar as nações a alcançar a prosperidade ou até a conflitos armados. Seria possível pensar numa aproximação entre a gestão do petróleo na cena internacional e as discussões mais amplas acerca da concepção de espaços internacionais mais horizontais, participativos e democráticos? Nessa direção, o artigo busca investigar a trajetória do petróleo como commodity energética mundial e o seu impacto na economia e na política contemporâneas. A hipótese do trabalho é que a governança petrolífera mundial nas primeiras duas décadas do século XXI tem sido baseada não apenas em regras de mercado, nacionalismo e cálculos realistas de poder, mas em possibilidades efetivas de cooperação internacional e de ganhos mútuos.

  9. How to stir a revolution as a reluctant rebel: Rudolf Trümpy in the Alps

    Science.gov (United States)

    Şengör, A. M. Celâl; Bernoulli, Daniel

    2011-07-01

    Rudolf Trümpy (1921-2009) was one of the great Alpine geologists of the twentieth century and an influential figure in the international geological community. He played a dominant role in the change of opinion concerning the Alpine evolution by showing that normal faulting dominated the early development of the Alpine realm from the Triassic to the early Cretaceous. This provided a convenient model for later plate-tectonic interpretations of collisional mountain belts. His further recognition of strike-slip faulting during all stages of the Alpine evolution presaged the realisation that the Alps were not built by a simple open-and-shut mechanism. Trümpy was educated during an intellectual lull, a time when simplistic models of the earth behaviour inherited from the middle of the nineteenth century became prevalent under the influence of a close-minded, positivist approach to geological problems. This period, which we term the Dark Intermezzo, lasted from about 1925 to 1965. The grand syntheses of Suess and Argand which preceded this period were viewed from this narrow angle and consequently misunderstood. It was thought that earth history was punctuated by global orogenic events of short duration taking place within and among continents and oceans whose relative positions had remained fixed since the origin of the planet. These views, summarised under the term `fixism', were developed when the ocean floors were almost totally unknown. When data began coming in from the post World War II oceanographic surveys, the world geological community was slow to receive and digest them. Trümpy followed these developments closely, realising that his work was important in placing the geology of the mountain belts within the emerging, new theoretical framework. He adopted the position of a critic and emphasised where detailed knowledge of the Alps, unquestionably the best known mountain belt in the world, supported and where it contradicted the new ideas. His voice was

  10. Comparing two distance measures in the spatial mapping of food deserts: The case of Petržalka, Slovakia

    2017-06-01

    Full Text Available Over the last twenty years or so, researchers’ attention to the issue of food deserts has increased in the geographical literature. Accessibility to large-scale retail units is one of the essential and frequently-used indicators leading to the identification and mapping of food deserts. Numerous accessibility measures of various types are available for this purpose. Euclidean distance and street network distance rank among the most frequently-used approaches, although they may lead to slightly different results. The aim of this paper is to compare various approaches to the accessibility to food stores and to assess the differences in the results gained by these methods. Accessibility was measured for residential block centroids, with applications of various accessibility measures in a GIS environment. The results suggest a strong correspondence between Euclidean distance and a little more accurate street network distance approach, applied in the case of the urban environment of Bratislava-Petržalka, Slovakia.

    Full Text Available Este artículo forma parte de una investigación sobre el efecto del precio del petróleo sobre el crecimiento económico en Colombia a nivel agregado y sectorial. La estimación del impacto se realiza a ambos niveles aplicando técnicas de series de tiempo. La evidencia sugiere que _este impacto existe y es asimétrico a nivel agregado. En el período de análisis la dinámica de los precios habría tenido efectos cambiarios que favorecieron la importación de bienes intermedios y de capital pero al mismo tiempo habrían tenido consecuencias negativas para las exportaciones sectoriales. La combinación de estos dos principales efectos sobre el comportamiento de la producción sectorial no es concluyente ni homogénea entre sectores.

    Molenaar, J C

    2003-11-08

    With the publication of Die Cellularpathologie in ihrer Begründung auf physiologische und pathologische Gewebelehre in 1858, the author Rudolf Virchow (1821-1902) originated the idea that each cell in each living organism, both plant and animal, originates from another cell and that the origin of disease can only be located in the cell. The book laid the foundations for cell pathology as a scientific discipline and was the most important publication by Virchow, who as doctor and statesman gathered so much fame that he became almost a mythical figure in his own time. The finding that every cell originates from another cell and does not develop from amorphous interstitium is actually attributable to Robert Remak.

    Full Text Available O artigo analisa a relação entre políticas sociais e economia no Brasil a partir da exploração do Pré-sal até os dias de hoje. O anúncio das reservas de petróleo na camada de Pré-sal resultou em rápidas alterações nas perspectivas econômicas, sociais e legais do país nas primeiras duas décadas do século XXI. A nova escala da produção petrolífera nacional seria a base para uma agenda de desenvolvimento econômico e social nos governos dos presidentes Lula e Dilma. Em seus respectivos governos ambos promoveram reformulações no marco regulatório do petróleo. A legislação foi alterada no tocante aos modelos de contrato, a distribuição dos royalties e o controle das reservas, assegurando ao Governo Federal maior soberania na extração, refino e distribuição do petróleo. As modificações legislativas e políticas visavam à destinação de parte dos lucros do Pré-sal para investimentos em infraestrutura e para políticas setoriais de desenvolvimento humano no Brasil.

    Directory of Open Access Journals (Sweden)

    Ingrid Nordgaard

    2016-11-01

    Full Text Available This article explores the concepts of pain and agency in the photography series Case History (1997–1998 by the Ukrainian photographer Boris Mikhailov, and in four performance-actions (2012–2014 by the Russian performance-activist Petr Pavlensky. Although they represent different generations and respond to different historical contexts, Mikhailov and Pavlensky share a focus on the wounded body. Taking both the documentary and performative aspects of these artworks into account, Nordgaard argues that the wounded body stands forth as a body of agency which also reflects the social, political, and historical settings in which it exists. The relational consideration of the two artists therefore offers important insights for understanding post-Soviet Ukraine and present-day Russia, and reflects on the correlation between the private and the public body. By placing Mikhailov and Pavlensky in dialogue with a broader discussion on spectatorship and the role and significance of “shock imagery” and spectacle in contemporary media, the article further suggests why artworks depicting the body in pain have both an ethical and political function.

Samples were collected along the year 2010 and their preparations were made after drying, milling, an acid pre-digestion and a decomposition procedure in a muffle furnace. The analytical techniques employed for the elements determination were Mass Spectrometry with Inductively Coupled Plasma and Flame Atomic Absorption Spectrometry. Two certified reference materials, Apple Leaves and Mussel Tissue, were used for the evaluation of the analytical procedure and recovery values around 98% were obtained. The results showed that the analyzed mushrooms have high levels of Cu, Fe, K, Mg, Mn and Zn containing more than 30% the recommended daily intake for these nutrients according to Brazilian legislation. These mushrooms presented a very low ratio Na/K. Regarding the levels of some contaminants, the mushrooms had concentrations of Cd, Pb and As below the recommended maximum limits allowed by Brazilian legislation.

Dessa maneira, tendo como princípio que a tectônica influencia diretamente a evolução da paisagem, os dados obtidos mostram uma interferência direta das estruturas na compartimentação morfotectônica e na dinâmica e evolução da paisagem da área em estudo.

    Full Text Available No Brasil atual, o turbulento contexto político, econômico e social tem sido terra fértil para o exame das práticas de gestão. Assim, o presente artigo tem por propósito investigar a realidade socioeconômica no município de Quissamã (RJ em conexão com a expansão dos recursos financeiros advindos do petróleo, que abasteceram os cofres públicos a partir de 1997. Para tanto, fez-se revisão bibliográfica e análise quantitativa de dados, fruto de pesquisa a documentos públicos da prefeitura. Nesta etapa, foram identificados os mecanismos de gestão e aplicação dos recursos originados no petróleo, como principais promotores do desenvolvimento local. Adicionalmente, foi estabelecida análise comparada entre Quissamã (RJ e o município vizinho Conceição de Macabu (RJ, visto que estes mantêm características territoriais e demográficas semelhantes. A despeito de Conceição não receber recursos do petróleo nos patamares de Quissamã, apresentou melhores índices de desenvolvimento. De resultado, verificou-se aumento da concentração de renda e a constatação de que os recursos públicos não geraram benefícios mais estruturantes para a população. Acredita-se que o debate proposto possa contribuir para o aperfeiçoamento das ações governamentais, restando salientar a necessidade de se aprofundar o que ora se discute, estabelecendo-se novos caminhos, num processo de melhoria da gestão de recursos públicos.

    Full Text Available Objetivos. Investigar las condiciones ambientales y el estado de salud de las mujeres que viven en comunidades rurales rodeadas por pozos y estaciones de petróleo en la Amazonía del Ecuador. Método. Se aplicó un diseño transversal comparativo, asignándose la exposición según la localización geográfica de las comunidades respecto a los pozos y estaciones de petróleo. Se analizaron muestras de agua de los ríos locales para determinar el contenido de hidrocarburos totales de petróleo y se proporcionó un cuestionario estructurado a cada cabeza de familia. El estudio se localizó en comunidades campesinas del nordeste del Ecuador y duró desde noviembre de 1998 hasta abril de 1999. Se incluyeron en el estudio nueve comunidades en el área expuesta (368 participantes y 14 en el área no expuesta (291 participantes. Resultados. Los ríos de las comunidades expuestas presentaron niveles de contaminación muy superiores al límite aceptado para el uso humano. Se encontraron diferencias significativas en las razones de prevalencia de hongos en la piel (RP 1,37; IC95% 1,01 a 1,86 en las dos semanas previas al estudio y de irritación de la nariz (RP 2,18; IC95% 1,64 a 2,91 y garganta (RP 1,68; IC95% 1,02 a 2,75 en los 12 meses anteriores. También se encontraron asociados con la exposición en las dos semanas previas el cansancio y "otros síntomas," y en los 12 meses anteriores, el dolor de cabeza, irritación ocular, dolor de oídos, diarrea y gastritis. Conclusiones. Los síntomas observados en las participantes de las comunidades expuestas concuerdan con los síntomas de toxicidad causados por el petróleo. Hay una necesidad urgente de establecer un adecuado programa de control y remediación ambiental que evite este innecesario e inaceptable riesgo para la salud de estas poblaciones.

    Full Text Available The “Pola” expeditions were the first to explore the deep Eastern Mediterranean Sea in the 1890s. They remained the most intense surveys in that area for a century and constitute today a fundamental baseline to assess change in the basin, whose fauna is still inadequately described. Solid taxonomic foundations for the study of deep-sea organisms are needed and we here contribute by revising the name-bearing types of mollusc species introduced by Rudolf Sturany on the basis of the “Pola” material from the Eastern Mediterranean Sea stored in the Natural History Museum in Vienna. Sturany introduced 15 names (Marginella occulta var. minor Sturany, 1896 shall not be considered as the introduction of a new name. He described and established two manuscript names by Monterosato: Jujubinus igneus and Pseudomurex ruderatus. The genus Isorropodon was also introduced together with its type species I. perplexum. For each name, we list the available type material, provide the original description and a translation into English and illustrate the specimens in colour and with SEM imaging.

    Full Text Available Resumen Se analiza la historia de la biorremediación de suelos contaminados con petróleo en la Amazonía ecuatoriana desde 1994 hasta 2014. Constatamos que si bien hubo “éxitos” tecnocientíficos, la oportunidad de cimentar un proceso de excelencia científica se vio frustrada por la carencia de voluntad política para gestionar la investigación. Parecen haber influido la dependencia de tecnología extranjera, la poca articulación interna entre programas de investigación e instituciones, la corrupción, la poca tradición innovadora en la biotecnología nacional, el predominio de biobraceros y una dicotomía construida entre petróleo y ambiente. Se articulan estos resultados en torno a debates sobre ciencia y tecnología en la periferia y se reflexiona sobre aspectos necesarios para consolidar procesos tecnocientíficos de excelencia en estos territorios.

    Full Text Available Em 1997, o governo brasileiro aprovou a Lei 9478/97, que estabelecia novos critérios para a distribuição de royalties do petróleo entre os municípios brasileiros e ampliou as possibilidades de uso desses recursos em áreas sociais. O objetivo deste artigo é investigar empiricamente se os royalties distribuídos sob esta lei contribuíram para a melhoria dos indicadores sociais dos municípios contemplados, em relação à média nacional, no período de 2000 a 2007. Utilizou-se o Índice Firjan de Desenvolvimento Social (IFDM e seus três componentes: IFDM - Educação, IFDM - Saúde e IFDM - Emprego&Renda, como medida de desenvolvimento social. Os resultados mostram que as rendas do petróleo não produziram impactos significativos nos indicadores sociais de saúde e de educação dos municípios beneficiados, mas, de forma surpreendente, geraram efeitos negativos sobre seus setores formais de trabalho.

    Full Text Available In this work, several results concerning mechanical grinding of cokes (recarburation, regular and combustible ones, obtained from refine processes of petroleum, are presented. A wide spectrum of sulphur content has been used, i.e from 0.23, 0.71 and 6 % (wt, respectively. The influence of several parameters, such as, speed and time have been studied. High energy planetary mills have been used; working in the range of 400 to 600 r.p.m. Different techniques have been used for the structural and morphological characterisation. Particle size distribution measuremets have been performed by means of a Laser-particle sizer. The average particle size found with this method has been 50 μm, after 16 hours of milling with a speed of 400 r.p.m. If grinding process is performed with a higher speed, this average particle size is achieved after only 8 hours of milling. Simultaneously, the specific surface of all milled cokes has been quantified with the milling time, seeing that this factor influences in the recarburation coke. The thermal behavior shows that the recarburation coke begins its decomposition (onset at decreasing temperatures with milling time. Oxygen and nitrogen have been measured, being their contents different for each coke, an increase of the content of oxygen with the milling time was observed in recarburation and regular cokes.

He was considered a pioneer of modern dance and a theorist of the dance movements. Particularly, his work was considered a breakthrough in the history of dance notation systems (Barbacci, 2002; Lepczyk, 2009, 2011. According to Barbacci (2002 Laban had a live marked by idealism and deep disillusions, on the one hand, he lived in the most important cultural cities in Europe (Paris, Vienna, Munich, Berlin, Zurich, and London where he met and kept contact with intellectuals and artists, this experience allowed him to be influenced by some theories such as “Naturphilosophie”, which developed a biological and romantic vision of movements. In fact, Laban considered the movement as a “Dance of Nature” (Barbacci, 2002. On the other hand, he also was influenced by negative disillusions because he lived through two World Wars, the Weimar Republic and also the origins of Nazism. Laban tried to study the movement from a natural perspective where man has a place in the universe, thus the movement is related to the mind and body, as well as to individuals and groups (Barbacci, 2002.

    2013-01-01

    Full Text Available In this text, Rudolf Brucci’s opera Gilgamesh is viewed in the light of Ralph Locke’s “All the Music in the Full Context” Paradigm which promotes the approach that one should search for the exotic elements in musical works first in the discursive components (title, program, accompanying notes, visual representations (costume, scenery and a “horizon of expectations” of a particular culture, and only then to observe exoticism as the aspect of a musical style. In the light of this Paradigm, “exoticism” of the opera Gilgamesh is detected at the level of the music material and compositional procedures, but not in the dramaturgical profiling of characters, narrative adaptation of the Sumerian epic, costumes and scenery. The plot, costumes and the scenery of the opera do not construct the Orient with either positive or negative projections attributed to it by the Western European Orientalist discourse, but portray Gilgamesh and Enkidu as ancient mythic protagonists on the margin of the (not-always exoticist once/now binarism. The musical language of the opera, which abounds in the usage of oriental musical scales and citations, indicates that oriental/exotic was one of the author’s “target levels” when conceiving and composing Gilgamesh. Brucci, however, did not build the “ethnological model” in his opera, but gave oriental scales and “exotic” musical citations their meaning within the Western musical tradition, which is why his approach can be compared with the “veiled exoticism” of the French composers of the late nineteenth and the early twentieth centuries. In the light of the self/other binarism, reaching for the exotic in Gilgamesh can be presented as an auto-exotic creative behavior of Brucci as a composer who perceives his “minority identity” in a relation to an imaginary referential system of the Center. However, I am more inclined to see Brucci’s identificational intention in his advocacy of the

    2007-12-01

    Full Text Available Este artigo apresenta um sistema de suporte à decisão para a otimização de alternativas de desenvolvimento de campos de petróleo. O desenvolvimento de um campo de petróleo consiste na escolha de uma alternativa para a explotação de um reservatório petrolífero, conhecido e delimitado, que permita produzir a maior quantidade de hidrocarboneto possível, dentro dos limites físicos e econômicos existentes, isto é, maximizar o valor presente líquido (VPL. O VPL é calculado a partir da produção de óleo, a qual é obtida com o uso de um simulador de reservatório. Cada execução do simulador pode demorar desde alguns segundos até várias horas, dependendo da complexidade do reservatório modelado. Isto reduz o número de alternativas que podem ser geradas e avaliadas pelo especialista na busca da melhor solução. Deste modo, o objetivo deste trabalho é propor e avaliar um sistema inteligente de otimização que emprega: algoritmos genéticos (AGs, algoritmos culturais (ACs e coevolução para a busca de uma alternativa de desenvolvimento ótima; e um ambiente de computação paralela para a simulação de reservatório e cálculo do VPL das alternativas. O sistema resultante permite que o especialista obtenha, em tempo hábil, a alternativa ótima (ou quase-ótima para o desenvolvimento de um campo de petróleo conhecido. Os resultados obtidos nos estudos de casos apresentados demonstram que o sistema proposto, baseado em técnicas inteligentes, obtém boas alternativas de desenvolvimento de campos petrolíferos com uma grande redução do tempo computacional, redução esta obtida a partir do aproveitamento do poder computacional de um ambiente de computação paralela e do aproveitamento de conhecimento do especialista, por meio das sementes iniciais.This paper presents an optimization system for the development of petroleum fields.

    Full Text Available En este trabajo se examina el crecimiento de la demanda interna del petróleo y sus derivados durante el periodo comprendido entre 1925 y 1938. En este lapso, México transitó de una industria eminentemente exportadora de petróleo crudo a la puesta en marcha de una refinadora, con la que el consumo interno de petróleo cobraría mayor relevancia. En este aumento del consumo fue importante la política económica de los gobiernos posrevolucionarios que, a través de estímulos fiscales, el establecimiento de organismos semioficiales y el control de precios favorecieron la expansión de este mercado.This paper examines the raising of oil products in domestic consumption along the 1925-1938 period. From just having mainly crude oil export industry, Mexico shifted towards a refining oriented one dealing with the internal oil market that would became so gready important. Finally, it is pointed out how the post revolutionary governments played a main roll on supporting the sustained growing of oil internal consumption through post revolutionary economical policies based on tax exemptions, sui generis social organizations and, last but not least, the oil price control established deliberately to strength the home expanding market.

    2017-08-01

    Full Text Available The Colombian Copyrights Office (dnda decided against the Colegio Montessori of Cartagena for infringing the moral rights of disclosure of Marcus Igno Rudolf Loerbroks. This case is important because it is one of the few decisions in which authors moral rights have been protected in Colombia. This ruling reveals the jurisprudential line that the dnda has gradually established for the protection of copyrights in our country, and especially for the moral rights enjoyed by the author of the art work as their owner. This is because, unlike the economic rights, moral rights are perpetual, inalienable and unassignable; as exposed in the case of the artist Gabriel Antonio Calle against the shopping mall San Diego and the case exposed in this review.

MÉTODOS : Estudo caso-controle (120 casos e 656 controles aninhado a um estudo de coorte retrospectivo com todos os trabalhadores de uma empresa de petróleo na Região Norte-Nordeste do Brasil entre 2007 e 2009. A variável resposta utilizada para representar o absenteísmo com licença médica foi a incidência média de faltas com licenças médicas no período, definida pela razão entre o total de dias de licenças médicas e os dias potencialmente trabalháveis no período. Análise de regressão logística foi utilizada para investigar a associação entre incidência média de faltas > 5,0% no período e as variáveis sexo, cargo, idade, tempo de atuação, regime de trabalho, tabagismo, hipertensão arterial, índice de massa corporal, atividade física, risco coronariano, sono, glicemia, diabetes não controlado, doença do aparelho cardiovascular, digestivo, aparelho locomotor, neurológica, neoplasia, posturas forçadas no trabalho, satisfação com o trabalho, relacionamento com a chefia e atenção concentrada no trabalho. RESULTADOS : A incidência média de faltas com licenças médicas > 5,0% no período da coorte foi 15,5%. O modelo logístico revelou que trabalhadores com incidência média de faltas > 5,0% tiveram 2,6 vezes mais chance de ser do sexo feminino; 2,0 vezes mais chance de ser fumante; 1,8 vez mais chance de ser ex-fumante, 2,2 vezes mais chance de relatar sono anormal e 10,5 vezes mais chance de estarem insatisfeitos com o trabalho do que trabalhadores com incidência média de faltas ≤ 5,0% no período. CONCLUSÕES : Sexo feminino, ser fumante ou ex-fumante, estar insatisfeito com o trabalho e relatar sono anormal são bons preditores de absenteísmo ao trabalho por doença.

    Full Text Available O Brasil é mundialmente renomado como um líder na extração de petróleo, em águas profundas e ultra profundas. Dentro da cadeia produtiva, grande parte do petróleo e do gás produzido é escoada através de dutos flexíveis que conectam os poços de produção às plataformas. Quando estão apoiadas no fundo do mar, em condição de serviço estático, os dutos flexíveis são denominados flowlines e quando se elevam do fundo do mar até a plataforma, em condição de serviço dinâmico, são denominados risers. Os tubos projetados para aplicações dinâmicas são dotados de bends stiffeners, componentes com formato cônico e, em geral, de base uretânica que têm a função de fornecer uma transição entre a estrutura dos tubos, de rigidez suave, e a plataforma, extremamente rígida. Este trabalho abordou a variação das propriedades mecânicas de poliuretanos como resultado da ação da hidrólise, por envelhecimento acelerado. Os corpos de prova foram expostos a 50, 60 e 70 ºC. A variação de massa também foi determinada considerando que esses materiais são projetados para uma vida útil superior a vinte anos. Os poliuretanos apresentaram degradação significativa a 70 ºC, o que pode reduzir seu tempo de aplicação no campo por falha mecânica quando submetido a elevadas temperaturas.Brazil is worldwide renowned as a leader in oil and gas extraction in deep and ultra deep water. In the production chain, a great part of the oil and gas produced is conveyed through flexible pipelines that connect the production wells to the platforms. When the pipes are laid on the seabed in a static service condition, the flexible pipes are called flowlines and when raised from the seabed to the platform in a dynamic service condition, they are called risers. The pipes designed for dynamic applications are equipped with bend stiffeners, components with conical form and in general based on polyurethanes, which have the function of providing a

    2016-04-01

    Full Text Available Resumen: El sector del petróleo y gas es un sector económico estratégico con repercusiones a escala global. Sin embargo, una de las principales limitaciones de esta industria radica en las características de las regiones en las que opera, ya que a menudo se trata de zonas geográficas de elevada importancia bioclimática, zonas con poblaciones indígenas o sectores rurales sumidos en la pobreza. Esto ha generado que los stakeholders presten cada vez más atención a las implicaciones sociales, naturales y económicas de las actividades del sector del petróleo y gas. Así las cosas, teniendo en cuenta que los países latinoamericanos cuentan con las mayores reservas convencionales mundiales de petróleo, el presente artículo tiene como objetivo cuantificar la información voluntaria sobre sostenibilidad que divulgan las empresas petroleras y gasíferas que operan en Latinoamérica.   Abstract:  The oil and gas sector is a strategic area of the economy with global repercussions. This industry faces a major handicap, namely the characteristics of the regions in which it operates, which are often geographic areas of great bioclimatic importance, or inhabited by indigenous populations, or comprised of very low income rural sectors. In response, stakeholders are paying ever greater attention to the social, natural and economic consequences of oil and gas sector activities. Taking into consideration that Latin American countries possess the largest conventional oil reserves in the world, this paper aims to quantify the sustainability information disclosed voluntarily by oil and gas companies operating in Latin America.

    Full Text Available Neste trabalho, avaliou-se o efeito do tempo de detenção hidráulica (TDH no desempenho de três reatores aeróbios inoculados com Aspergillus niger AN400, usados para tratamento de efluentes de refinarias de petróleo. Cada reator foi operado com um tempo de detenção hidráulica diferente: 4, 8 e 12 horas, durante 152 dias. Eles possuíam leito fixo de espuma de poliuretano e o escoamento era ascendente e contínuo. Determinaram-se: pH, fenóis, demanda química de oxigênio (DQO, amônia, nitrito e nitrato, no afluente e efluentes dos reatores. O TDH de oito horas foi o melhor para remoção de DQOsolúvel e não houve diferença entre os TDHs para remoção de fenóis totais. No período estável não houve remoção de nitrato; no entanto ocorreu remoção de nitrito de aproximadamente 99%. Além disto, houve produção de amônia devido à amonificação a partir do nitrito presente no meio.This paper evaluated the effect of hydraulic retention time (HRT on the performance of three upflow aerobic reactors, with polyurethane foam as support material, inoculated with Aspergillus niger AN400, used for the treatment of petroleum refinery wastewater. Each reactor was operated with a different HRT: 4, 8 and 12 hours, during 152 days. The performance was evaluated based on pH; phenols; COD, nitrate and nitrite. The results show that for the COD removal, it is more reasonable to operate the reactor with HRT of eight hours. However, there was no difference among results of phenol removal efficiency of the different HRTs. During steady state condition, nitrite was removed in approximately 99%, but there was no reduction on the nitrate concentration. Ammonia was produced in all reactors, probably due to ammonification of nitrite.

    Full Text Available In this paper we analyze the proposition that the theologian Rudolf Bultmann made on the subject of faith. We describe the mutual influences between Martin Heidegger and Bultmann from specially developed joint work in Marburg in 1923 and 1924. The author shows that, although Heidegger’s existential philosophy represented an important influence to Bultmann, the latter develops a more theological approach that characterizes faith as an existential and eschatological event that requires a decision on the part of the listener. Bultmann also remains faithful to its Lutheran heritage to take away the anthropological approach of existentialism, stating the total character of the fall of man that makes him unfit to achieve for itself «real life» dimension can be realized only by through faith in Christ crucified. The latter is for Bultmann the real scandal of the Gospel and not the «fake scandal» of the pre-scientific vision of the New Testament kerygma. This research aims to demonstrate that demythologizing, which becomes an insurmountable hurdle for many readers of Bultmann, was just a method to facilitate faith in the gospel by modern man. Consequently, to paraphrase Immanuel Kant, Bultmann seems to say: «I had to let go of the myth to give rise to faith».

    Full Text Available OBJECTIVES: This study aims to detect the prevalence of common mental disorders among patients seen by doctors at family health program units in Petrópolis-RJ, and to establish their nosological profile. METHOD: The population of the study included all 18 to 65-year-old patient who attended any family health program units included in the study during a 30-day period, between August and December 2002 (n = 714. The prevalence of common mental disorders was assessed using the General Health Questionnaire, 12 item version. In order to establish the nosological profile, the Composite International Diagnostic Interview was administered to all common mental disorders positive patients who accepted to return (n = 215. RESULTS: At the cut-off point of 2/3 the common mental disorders prevalence was 56% and for 4/5, it was 33%. The most frequent nosological categories found among common mental disorders positive patients were depression and anxiety categories along with posttraumatic stress disorder, somatoform pain disorder and dissociative disorders. There was a high frequency of comorbidity, especially between anxiety, depression, somatoform and dissociative disorders. CONCLUSIONS: The common mental disorders prevalence and the nosological profile found in FHP were similar to those of other primary care studies in Brazil, but some disorders (posttraumatic stress disorder, somatoform pain disorder and dissociative disorders that had not been previously studied in this context were also very frequent. The high common mental disorders prevalence found reinforces the urgent need for systematic inclusion of this level of care in mental health assistance planning.OBJETIVOS: Conhecer a prevalência de transtornos mentais comuns na clientela atendida no Programa de Saúde da Família (PSF em Petrópolis-RJ e seu perfil nosológico.

The selection of real assets by companies did not incorporate the mean-variance optimization procedure in the same way the selection of financial assets in investment portfolios did. The process of selection and formation of portfolios of investment projects for the oil area of a company in the energy industry was analyzed. Project portfolios formed according to the usual company practice of ranking by their PI were compared with those that result from applying mean-variance optimization through Monte Carlo simulation, which allows the computation of mean returns, variances, and covariances for the set of projects considered. The inefficiency of project portfolios obtained by ranking according to the PI compared to those obtained by the method of Markowitz suggests that there are opportunities to improve the process of selecting the set of projects to be implemented by companies.O objetivo deste artigo é comparar a seleção de projetos de investimento segundo a fronteira eficiente no espaço média-variância com base em modelos de otimização introduzidos por Markowitz (1952 com o método do ordenamento de projetos segundo o índice de lucratividade (IL.

    Full Text Available ResumoOs efeitos da aplicação das rendas petrolíferas para o desenvolvimento socioeconômico e o financiamento de políticas públicas têm sido questionados na literatura. O objetivo principal deste estudo foi analisar a importância das compensações financeiras – royalties e participação especial – para o financiamento municipal da saúde na região Norte Fluminense do estado do Rio de Janeiro, que é responsável por mais de 70% do petróleo produzido no Brasil. A metodologia envolveu a análise de dados secundários das receitas e despesas municipais com saúde nos anos 2000. Os resultados sugerem que a variação de recursos orçamentários relacionados ao petróleo se associou à diferença significativa na despesa total com saúde nos municípios da região. No entanto, a execução e a distribuição das despesas por tipo não ocorreram de forma proporcional à variação na disponibilidade das receitas. A forte dependência das rendas petrolíferas sugere maior autonomia municipal no gasto em saúde se comparado a outros municípios do país. Conclui-se que é preciso estabelecer outros critérios de distribuição e uso de recursos para favorecer a equalização dos gastos e a articulação entre as ações dos governos no ambiente regional.

    Full Text Available The aim of this study was to investigate the feasibility of using apple filter cake, a fruit-processing waste to enhance the bioremediation of petroleum contaminated soil. A rotating barrel system was used to study the bioconversion of the xenobiotic compound by natural occurring microbial population. The soil had been accidentally polluted with a total petroleum hydrocarbon concentration of 41,000 ppm. Although this global value was maintained during the process, microbial intervention was evidenced through transformation of the petroleum fractions. Thus, fractions that represent a risk for the environment (GRO, Gasoline Range Organics i.e., C6 to C10-12; DRO, Diesel Range Organics i.e., C8-12 to C24-26 and RRO, Residual Range Organics i.e., C25 to C35 were significantly reduced, from 2.95% to 1.39%. On the contrary, heavier weight fraction from C35 plus other organics increased in value from 1.15% to 3.00%. The noticeable diminution of low molecular weight hydrocarbons content and hence environmental risk by the process plus the improvement of the physical characteristics of the soil, are promising results with regard to future application at large scale.O objetivo deste estudo foi investigara viabilidade de aplicação de bagaço de maçã, um resíduo do processamento de frutas, para melhorar a biorremediação de solo contaminado com petróleo.

    Kalvius, G. M.; Kienle, P.

    Mössbauer and one of the authors (PK) started in 1949 studying physics at the Technische Hochschule München (THM), which was still under reconstruction from the war damages. It offered two directions for studying physics: "Physik A" and "Physik B." I took courses in "Physik A," which meant Technical Physics; Mössbauer studied "Physik B," which was General Physics. Actually, the lectures of both directions were not too different up to the forth semester, followed by a "pre-diploma" examination, which Mössbauer passed in 1952. I as "Physik A" student had besides the various physics, chemistry, and mathematics courses, in addition lectures in Technical Electricity, Technical Mechanics, Technical Thermodynamics, and later Measurement Engineering offered by very famous professors, such as W.O. Schumann, L. Föppl, W. Nußelt, and H. Piloty. Our physics teachers were G. Joos (Experimental physics), G. Hettner (Theoretical Physics), and W. Meissner (Technical Physics); in mathematics, we enjoyed lectures by J. Lense and R. Sauer, and interesting chemistry lectures by W. Hieber. Thus we received a high-class classical education, but quantum mechanics was not a compulsory subject. Mössbauer complained about this deficiency when he realized that the effect he found was a quantum mechanical phenomenon. Quantum mechanics was offered as an optional subject by Prof. Fick and Prof. Haug. Mössbauer just missed to take these advanced lectures, although he was highly talented in mathematics and received even a tutoring position in the mathematics institute of Prof. R. Sauer, while I worked in engineering projects and had extensive industrial training.

    Full Text Available La refinería cubana produce muchos productos para el mercado cubano como los combustibles, aceites, asfaltos y Jet-A1. Los sistemas auxiliares como vapor, aire comprimido y agua se utilizan para la obtención de los productos derivados del petróleo. La generación de vapor es uno de los sistemas auxiliares más importantes dentro de la refinería. La caldera de vapor garantiza que el vapor tenga las condiciones de operación de acuerdo con las normas internacionales. En este trabajo, se realizó la evaluación energética de F1-2 y BH-109 de calderas que utilizan los balances de energía y de masas convencionales. Se obtuvo una eficiencia energética de 61,89 y 77,31 por ciento para F1-2 y BH-109, respectivamente. Las principales pérdidas se debieron al calor sensible de los gases de combustión y a la combustión no química. Para reducir estas pérdidas, mejorar el rendimiento de la caldera y disminuir la temperatura de los gases de salida, se recomienda montar el sistema de control de exceso de aire y volver a examinar o cambiar el sistema de inyección de aire.

    Full Text Available This study aimed at evaluating potential differences among the bacterial communities from formation water and oil samples originated from biodegraded and non-biodegraded Brazilian petroleum reservoirs by using a PCR-DGGE based approach. Environmental DNA was isolated and used in PCR reactions with bacterial primers, followed by separation of 16S rDNA fragments in the DGGE. PCR products were also cloned and sequenced, aiming at the taxonomic affiliation of the community members. The fingerprints obtained allowed the direct comparison among the bacterial communities from oil samples presenting distinct degrees of biodegradation, as well as between the communities of formation water and oil sample from the non-biodegraded reservoir. Very similar DGGE band profiles were observed for all samples, and the diversity of the predominant bacterial phylotypes was shown to be low. Cloning and sequencing results revealed major differences between formation water and oil samples from the non-biodegraded reservoir. Bacillus sp. and Halanaerobium sp. were shown to be the predominant components of the bacterial community from the formation water sample, whereas the oil sample also included Alicyclobacillus acidoterrestris, Rhodococcus sp., Streptomyces sp. and Acidithiobacillus ferrooxidans. The PCR-DGGE technique, combined with cloning and sequencing of PCR products, revealed the presence of taxonomic groups not found previously in these samples when using cultivation-based methods and 16S rRNA gene library assembly, confirming the need of a polyphasic study in order to improve the knowledge of the extent of microbial diversity in such extreme environments.Este estudo teve como objetivo comparar as comunidades bacterianas de amostras de água de formação e de óleo de reservatórios de petróleo brasileiros com diferentes graus de biodegradação usando a técnica de PCR-DGGE.

    Full Text Available OBJETIVO: verificar a prevalência de obesidade entre adultos das 86 famílias agricultoras de um bairro de Petrópolis, RJ, e analisar seus determinantes socioculturais. MÉTODOS: estudo quantitativo e qualitativo sobre nutrição, práticas alimentares e de trabalho realizado em 2008. Dados antropométricos foram coletados por inquérito nutricional domiciliar e o material qualitativo por observação participante e entrevistas. RESULTADOS: a prevalência de obesidade foi baixa (9,3% entre os homens, mas bastante elevada entre as mulheres (29,9%. A prática agrícola local implica em atividade física leve para mulheres e intensa para homens. Essa diferença não é acompanhada na dieta, semelhante para homens e mulheres, com predomínio de alimentos de alto valor calórico. A produção familiar objetiva essencialmente a venda. A agricultura mercantil e a decorrente especialização dos cultivos favorecem comprar alimentos no mercado em vez de produzir para autoconsumo. CONCLUSÃO: os aspectos socioculturais e ocupacionais estudados podem ter contribuído para elevar a prevalência de obesidade nas mulheres e podem ser úteis no estudo de outros grupos com características semelhantes. Esta pesquisa ratifica a importância de estudar a obesidade em nível local, integrando abordagens quantitativas e qualitativas para identificar possíveis limitações e portas de entrada para ações de intervenção localmente relevantes.

    Full Text Available A obtenção de piches mesofásicos para a produção de fibras de carbono de alta performance foi investigada por meio de tratamento térmico de três piches de petróleo, em dois estágios em um reator com agitação magnética e capacidade de 700 g. O primeiro estágio consistiu de um pré-tratamento sob agitação e atmosfera de nitrogênio a 0,9 MPa, a 390, 410 e 430 °C, durante três horas. No segundo estágio, o tratamento térmico foi realizado por mais três horas, sob pressão atmosférica. Durante os experimentos, amostras foram recolhidas e analisadas por meio de medidas de solubilidade em tolueno e quinolina, ponto de amolecimento e o percentual de mesofase. Foi verificado que, para todos os piches produzidos, nas temperaturas de 390 e 410 °C a variação dos parâmetros físico-químicos foi muito pequena e que os tratamentos térmicos no patamar de 430 °C produziram piches com pontos de amolecimento acima de 300 °C, e percentual de mesofase próximo a 70%.Mesophase pitches, precursors of high-performance carbon fibers, were prepared from petroleum pitch by a two-stage heat treatment, in a reactor capable of heat treating 700 g of petroleum pitch under stirring. The process consisted of a pretreatment under pressure at 390, 410 and 430 °C under nitrogen atmosphere, at 0.9 MPa, for three hours, as the first stage, followed by another heat treatment under atmospheric pressure, as the second stage. To study the properties of the petroleum pitch samples, during the experiment, they were removed from the system. Quinoline insolubles, toluene insolubles, mesophase content and softening point of the samples were used to follow the pyrolysis process. The results revealed slight variations in the properties for the pitches produced at 390 and 410 °C. However, the pitch samples produced at 430 °C had softening points higher than 300 °C, and mesophase contents of around 70%.

Nosso objetivo na reflexão aqui empreendida é: (a verificar, com base em um caso específico, a questão do papel que exerce a dimensão humana na confiabilidade de sistemas de elevada complexidade - com foco na gestão de situações incidentais e acidentais -, capazes de acarretar acidentes de grande magnitude. E, ao nos debruçarmos sobre tal intento, somos remetidos à necessidade de (b dar visibilidade à interveniência de alguns dos fatores organizacionais como elementos que podem contribuir para agravar o grau de risco da atividade em plataformas offshore, conduzindo a análise para além das chamadas causas imediatas. No que tange aos métodos de investigação, tomamos por base, principalmente, a pesquisa documental (com destaque para os relatórios da Petrobras, ANP/DPC e CREA-RJ e as interlocuções que mantivemos com três profissionais que atuaram na P-36. Os resultados indicam que a gestão das situações incidentais e acidentais, na qual se circunscrevem as tomadas de decisão em contextos emergenciais, deve se valer da contribuição que os trabalhadores podem agregar no sentido de apontar e discutir com os gestores certas lacunas do processo, por intermédio do compartilhamento e da flexibilização de decisões e da análise coletiva das situações de risco. Indicam também que determinados fatores organizacionais contribuíram para a ocorrência do sinistro, corroborando estudos nacionais e internacionais acerca de grandes acidentes, que apontam para a necessidade de mudança no enfoque adotado pela gerência das empresas do setor petrolífero.

    Full Text Available The rivers and floodplain lakes of the Urucu petroleum-bearing region in central Amazonia are extensively colonized by aquatic macrophytes, which may be affected by accidental spills during oil extraction and transportation operations. Among the species of macrophytes, the free-floating Eichhornia crassipes (water hyacinth is abundant; AIM: The objective of this study was to evaluate the effect of different dosages of Urucu crude oil (0, 0.5, 1.5 and 3.0 L.m-2 on the biomass of E. crassipes and on some physical and chemical characteristics of the water in which the plant grew; METHODS: The experiment was conducted over a period of 84 days. Every seven days, the biomass (live and dead of E. crassipes and the temperature, pH, electrical conductivity and dissolved oxygen in the water were measured; RESULTS: The dosage of 0.5 L.m-2 was sufficient to cause partial mortality (48% in E. crassipes after 35 days of exposure to oil. The dosage of 3.0 L.m-2 caused total mortality (100% in E. crassipes after 84 days of exposure. The decomposition of the oil and the dead biomass of E. crassipes reduced the dissolved oxygen and pH, and increased electrical conductivity and concentrations of total phosphorus in the water; CONCLUSIONS: We conclude that an oil spill can cause total mortality in the local population of one macrophyte species, but not of another. This may alter the macrophyte species diversity in the impacted region. In the case of E. crassipes and Pistia stratiotes, an Urucu crude oil spill could favor E. crassipes, the species less sensitive to oil.Os rios e lagos de várzea da província petrolífera de Urucu, na Amazônia Central, são amplamente colonizados por macrófitas aquáticas, que podem ser afetadas por acidentes durante a exploração e o transporte de petróleo.

    Full Text Available Devido aos grandes desafios encontrados na perfuração de poços, há a necessidade de se desenvolver fluidos com propriedades adequadas e capazes de atender todas as exigências da perfuração, como elevada capacidade de carreamento de sólidos e alta lubricidade, como também fluidos ambientalmente corretos. O grau de impacto dos fluidos de perfuração no meio ambiente depende especialmente do tipo de fluido utilizado, se de base aquosa, oleosa, sintética ou mesmo de base ar. Portanto, é de fundamental importância o desenvolvimento de fluidos com características específicas em cada etapa da perfuração. Sendo assim, este trabalho objetivou o desenvolvimento de fluidos aquosos, com baixo teor de sólidos e propriedades reológicas, de filtração e lubricidade adequadas à perfuração de poços de petróleo onshore. Os fluidos foram formulados utilizando em sua composição bentonita sódica industrializada, aditivos poliméricos e lubrificantes, em diferentes concentrações. O estudo reológico, de filtração e lubricidade mostrou que os fluidos apresentam comportamento pseudoplástico e que os aditivos selecionados desempenham com êxito suas funções de modificadores reológicos, redutores de filtrado e agente lubrificante. Além disto, ficou evidenciada a necessidade de aditivos lubrificantes em fluidos aquosos contendo argila bentonítica e polímeros. A adição de 1% de lubrificante no fluido é suficiente para adequar a capacidade lubrificante dos fluidos.Due to challenges encountered in drilling wells, there is a need to develop fluids that have properties suitable and able to meet all the requirements of drilling, such as, high capacity for carrying of solid and high lubricity. Besides that, they need to be environmentally friend. The degree of impact of drilling fluids in the environment depends on the type of fluid used, if water or oil or synthetic or air based.

    Full Text Available Na indústria petroquímica a unidade de craqueamento catalítico fluidizado de petróleo é um importante equipamento para aplicação de concretos refratários devido à necessidade de se obter produtos especializados. Normalmente, a seleção destes materiais é baseada na análise química e em medidas de densidade aparente, resistência mecânica por compressão uniaxial e erosimetria a frio. Para avaliação dos requisitos de seleção usuais, cinco concretos de alta alumina, sendo três de baixo teor de cimento e dois convencionais de uso comercial, foram avaliados por resistência à compressão e erosimetria a frio. Testes complementares que atualmente não são utilizados no processo de seleção também foram realizados, tais como: resistência ao choque térmico, módulo de ruptura a quente e exposição em atmosfera de CO. A análise mostrou que as especificações vigentes são baseadas principalmente na experiência com a utilização de produtos não originalmente projetados para esta aplicação e que o desenvolvimento de produtos mais adequados é inibido pelas restrições das especificações atuais. Também se verificou que a seleção é limitada pela falta de ensaios que avaliem o desempenho em condições mais próximas das de uso. Neste sentido, o teste de resistência à deposição de carbono pela exposição em atmosfera de CO mostrou-se interessante por contribuir para uma melhor seleção dos concretos refratários densos antierosivos.In the petrochemical industry the fluidized catalytic cracking unit is an important vessel for refractory castables application due the necessity of obtaining specialized products. Usually, the selection of these materials is based on the chemical analysis, apparent density, cold crushing strength and cold erosion test. For the evaluation of the present selection requirements, five high-alumina castables, being three of low cement and two conventional of commercial use, were

    Full Text Available Estudo transversal com o objetivo de identificar os fatores associados à síndrome metabólica (SM em trabalhadores administrativos de uma indústria de petróleo. Avaliou-se 1.387 trabalhadores, incluindo dados antropométricos, bioquímicos, estilo de vida, características demográficas e socioeconômicas. Determinou-se a SM segundo a I Diretriz Brasileira de Diagnóstico e Tratamento da Síndrome Metabólica. Os fatores associados à SM foram examinados por modelos de regressão logística univariado e multivariado. 15% dos trabalhadores apresentaram a SM. Na análise multivariada, o sexo (OR=3,4;IC 95% 2,1-5,5, a idade (OR=3,8;IC 95% 1,5-9,4 e o tabagismo (atual e passado (OR=1,6;IC 95% 1,2-2,3, foram associados à SM. Conclui-se que a prevalência da SM nestes trabalhadores é elevada, especialmente em homens, tabagistas ou ex-tabagistas e com idade acima de 40 anos. Possivelmente, o maior valor deste diagnóstico foi possibilitar a identificação de trabalhadores com alterações metabólicas extremas, que justifiquem intervenções imediatas para redução dos fatores de risco identificados. Nesse sentido, ações que objetivam a promoção de estilo de vida saudável, poderão ser desenvolvidas pelas empresas, visando a contribuir para a melhoria das condições de saúde dos empregados.This is a cross-sectional study seeking to identify the factors associated with metabolic syndrome in administrative workers of an oil company.

A análise dos relatórios ambientais de 21 empreendimentos nacionais de produção de petróleo, licenciados no período de 1º de janeiro de 2004 a 31 de outubro de 2009, constatou a inexistência de evidências da incorporação de aspectos de saúde na maioria dos seus respectivos estudos de avaliação de impacto ambiental. A matriz mostrou-se um instrumento metodológico adequado para analisar a inserção da saúde no licenciamento ambiental e orientar a tomada de decisão e intervenções para a gestão socioambiental.Bearing in mind the importance of the impacts of the oil industry on human health, this article seeks to present a methodological proposal for analysis of these aspects in environmental impact assessment studies, based on the established legal parameters and a validated matrix for the hydroelectric sector. The lack of health considerations in the environmental impact assessment was detected in most of the 21 oil production enterprises analyzed, that were licensed in the period from January 1, 2004 through October 30, 2009. The health matrix proved to be an appropriate methodological approach to analyze these aspects in the environmental licensing process, guiding decisions and interventions in socio-environmental management.

    Full Text Available A Participação Especial captura parte da renda extraordinária de campos petrolíferos com grande volume de produção, a exemplo do Pré-sal ou campos maduros da Bacia de Campos. Considerando a complexidade desta participação governamental, este artigo analisa seus determinantes e impactos em projetos de petróleo em diferentes cenários: produção isolada com um módulo e lavra com mais módulos. A metodologia inclui elaboração de fluxos de caixas dos projetos e estimativa do VPL, utilizando simulações estocásticas. Os resultados obtidos dos modelos de simulação indicaram a existência de ineficiência/ distorções causadas pela Participação Especial: tanto na sua forma de incidência (alíquotas, como na sua base de cálculo que se manifestam em campos gigantes de petróleo, com diferentes características (até um bilhão de barris - limite utilizado no estudo e campos nos quais ocorre adição de reservas, pois o segundo módulo é onerado, podendo comprometer a viabilidade econômica deste projeto, conforme nível de preços praticados.The special participation fee is used to capture the rent originated from oil production fields with a great production profile, like Pre-salt or brown fields in Campos Basin. Considering the complexity of this fee, in this paper different forms of its impacts in the oilfields projects are considered: a production profile generated by only one production module and by more modules. The methodology combines the cash flow analysis from the projects and NPV estimations, using stochastic simulations. The results obtained from the simulation models indicated inefficiencies generated, both in its form of incidence and rates as well as in its estimation process. This type of distortion occurs for giant oilfields with different characteristics (reserves up to 1 billion barrels, simulation cut-off volumes used in this study and for those fields with reserves additions.

Se obtuvieron ecuaciones de regresión que relacionan a la temperatura máxima en la superficie interna del tubo y al tiempo de enfriamiento desde 800 ºC hasta 500 ºC de un punto situado en la zona afectada por el calor (ZAC, parámetros que gobiernan la ocurrencia de perforaciones en la pared del tubo y agrietamiento en frío respectivamente, con el calor de entrada de la soldadura, la temperatura de precalentamiento y el coeficiente de transferencia de calor por convección, variables que definen el comportamiento térmico durante la ejecución del proceso de soldadura. Se probó la existencia de una zona en que se satisfacen simultáneamente las ecuaciones obtenidas, para diferentes combinaciones de las variables relacionadas. Se presentaron nomogramas con un importante valor práctico, desarrollados a partir de la solución de las ecuaciones obtenidas.The thermal behavior during in service repair welding of oil transportation pipes was studied by finite element analysis in the present paper. Regression equations that relate peak temperature at the inner surface of the pipe and cooling time between 800 and 500ºC in the heat affected zone to the welding heat input, preheat temperature, and convection heat transfer coefficient were obtained. The former parameters govern, respectively, the possibility of burn through and cold cracking, and the latter parameters define the thermal behavior during welding. The existence of conditions that simultaneously satisfy the obtained equations, for different combinations of related variables, was proved. Graphical representations of relevant practical importance that were developed from the solution of obtained equations are presented.

Além de afetar os próprios trabalhadores, têm o potencial de afetar populações vizinhas e causar danos ambientais. A partir de uma ação de vigilância em saúde do trabalhador envolvendo diversos órgãos públicos, analisam-se, aqui, as causas de 800 eventos ocorridos em uma refinaria de petróleo no Estado do Rio de Janeiro (Brasil, no ano de 1997, e que resultaram em lesões em trabalhadores diretos e terceirizados, perdas ou parada da produção, danos à equipamentos e materiais e conseqüências sobre o meio ambiente. Na metodologia utilizada, adotaram-se abordagens que privilegiam os aspectos gerenciais e organizacionais na origem dos acidentes, sendo utilizado como referência o sistema de registro de acidentes em indústrias perigosas utilizado pela União Européia. A partir dos resultados, verifica-se que há limites na investigação e registro dos acidentes, bem como uma nítida hierarquização pela empresa, caracterizada por uma menor atenção aos trabalhadores terceirizados e pela realização de melhores registros para os eventos que afetam diretamente a produção.Accidents in the chemical industry can have serious consequences for workers, communities, and the environment and are thus highly relevant to public health.

    Full Text Available O gerenciamento da água produzida (AP de petróleo se constitui em um enorme desafio para as empresas petrolíferas. As alternativas usualmente adotadas para o seu destino são o descarte, injeção e o reúso. Em todos os casos é necessário tratamento da AP, a fim de evitar danos ao meio ambiente e às instalações de produção ou a fim de permitir o seu reúso sem causar prejuízos aos processos nos quais a AP será utilizada. Os processos de separação por membranas (PSM têm se mostrado capazes de tratar efluentes que apresentam elevados teores de óleo em emulsão e de partículas com tamanhos médios e pequenos, competindo, assim, com tecnologias de tratamento mais complexas, tais como flotação. O objetivo deste artigo foi apresentar uma revisão sobre o tratamento de AP utilizando os PSM discutindo os principais aspectos da AP e os aspectos conceituais dos PSM, com ênfase para sua aplicação para remoção de óleo da AP.The management of oil produced water (PW constitutes a major challenge to oil companies. The options usually adopted for PW are disposal, injection and reuse. In all cases, a PW treatment is required in order to avoid damages to the environment and to production facilities or to allow its reuse without causing damage to processes in which the PW is used. The membrane separation processes (MSP has been shown to be capable of treating effluent with high content of emulsified oil and with medium and small sizes particle, competing well with more complex treatment technologies such as flotation. The aim of this paper was to present a review of the PW treatment by MSP, discussing the main aspects of the PW and the conceptual aspects of the MSP, with emphasis on their application for removal of oil from the PW.

    The spiritual well-being of children is often thought to be an important goal and outcome of education. Such spiritual well-being is also implicitly assumed by the Human Rights Act, which includes the right to "freedom of thought, conscience and religion" [Article 18]. I argue that such freedom requires an education that fosters development of…

    Full Text Available udolf SCHMITT ist unbestreitbar ein fundierter Experte im deutschsprachigen Raum im Hinblick auf eine umfassende und fokussierte Metaphernanalyse als ein spezifisches Verfahren der Analyse qualitativer Daten. Mit seiner in FQS erschienenen Rezension zu unserem Buch "Metaphernanalyse. Ein rekonstruktiver Ansatz" wird dies abermals deutlich. SCHMITT ordnet unser Verfahren zur rekonstruktiven Metaphernanalyse in andere sozialwissenschaftliche Metaphernanalysen ein und versucht auf dieser Grundlage, Vor- und Nachteile unseres metaphernanalytischen Zugangs hervorzuheben. Ausgehend von diesem Vergleichshorizont gelingt ihm die Besprechung eines grundlegenden Buches zur Einführung in die sozialwissenschaftliche Metaphernanalyse – welches unser Buch aber weder ist noch vorgibt zu sein. Wir begrüßen seine breit gefächerte Auswahl sozialwissenschaftlicher metaphernanalytischer Zugänge, glauben aber, dass die Zielsetzungen unseres Ansatzes (und unseres Buches in seinem Review-Essay zu sehr in den Hintergrund treten. Wir haben uns daher zu dieser Replik entschlossen, um die "sozialwissenschaftliche Metaphernanalyse" weiter in einem diskursiven Prozess zu halten.

  14. Humanistic Approach to Early Childhood Education in the Educational Philosophy of Rudolf Steiner

    Directory of Open Access Journals (Sweden)

    Dragana Pavlovic

    2017-09-01

    Full Text Available The unassailable empirical fact that Waldorf education has existed, endured and evolved for almost a century. It provides one with a legitimate propensity to engage and research into humanistic aspects of early childhood education in Steiner’s philosophical and pedagogical inclinations. In that respect, the first development cycle, which refers to the education of children in early years of development, represents the foundation of any further growth, as well as of structuring a healthy qualitatively-voluntaristic personality aspect. The essential feature of early childhood can be observed in a complex interplay of a myriad of holistic and integrative elements of a child’s sensitive nature during this period. The paper aims to provide humanistic insights into Steiner’s pedagogical oeuvre that, as a methodological basis, reflects in a rather explicit and applicable manner the necessity of a pedagogical conception of the uniqueness of childhood and children, whose forces ought to be preserved. It is concluded that a genuine global social renaissance, starting from a given present as a relative uncertainty towards a better future as a possible certainty, i.e. towards the humanised and humanistic, is possible only if education is understood as a true social power with reformed and revalued educational system. Steiner perceived exciting prospects for human beings in the absolute freedom that is inherent in every human being as a spiritual power, so in early childhood years it is necessary to model temporal and spatial circumstances which support and generate a child’s practice as a sensitive organ of a complex field of interactive exchange.

A tal fin, se atiende de modo particular a la presencia de nuevas tecnologías percibidas, en general, como parte de la avanzada neo colonizadora en que se convirtió, para la mayoría de los escritores venezolanos del momento, la presencia de las compañías extranjeras.

    2008-01-01

    Full Text Available The economic exploitation of hydrocarbons at the Petroliferous Province of Urucu, located at 280 kilometers from the center of Coari/AM municipality, occurs inside in one of the planet’s most environmentally sensitive areas, the Amazon forest. The municipality of Coari/AM, due to economic exploration in its territory, is experimenting significative transformations in the use of its soil. The objective of this research was to diagnose, from the point of view of sustainable development, the institutional and political contextof how this economic exploration is happening, starting in 1987 up to today. Furthermore, it also has the objective of analyzing the main transformations in the use of the soil. The methodology, regardingthe spatial variation of the soil use, employed techniques of geoprocessing and of processing of digital images taken from orbital remote sensors, encompassing a 17-year period of imaging in the study area. The study also analyzed social, economic and political indicators, as well as data obtained during the field trips and interviews with the main stakeholders. The methodology developed prospective, tendentialinertial and normatives scenarios, related to the exploitation of hydrocarbons. The results obtained with the application of the proposed methodology led to the conclusion that there is significant environmental damage, resulting from the activities of hydrocarbons exploitation as well as the human expansion in the urban areas of the municipality. Moreover, the hydrocarbons exploitation almost doubled the population of the municipality in 16-year period, taking a severe toll in the municipality infra-structure and the quality of local life. Moreover, this expansion process still continues. The stakeholders, endowed with decision power, have not created mechanisms to guarantee intergeneration justice to the population of Coari, its major social actor, using the criterion of proximity of the undertaking. The significant economic resources that come from the government participation financial resources in the hydrocarbons exploitation have not been able to avoid the low indices in the local quality of life and the few self sustainable alternatives. The research suggests actions and inductive policies, which may contribute to change the current trends of unsustainable growth of Coari, making it independent of the foreseeable depletion ofits hydrocarbons reserves.

    Full Text Available RESUMEN: Colombia es productor y exportador medio de crudo con costos entre altos y moderados. En los últimos 20 años, transitó de los contratos de riesgo compartido a las concesiones y la privatización parcial de ECOPETROL. Los objetivos fueron incrementar las inversiones en exploración, prolongar la vida útil de las reservas y garantizar la autonomía energética nacional, los ingresos fiscales y de divisas. La evaluación de la privatización parte de la apreciación del estado financiero de ECOPETROL, las utilidades antes y después de impuestos y los cambios en la relación entre utilidades brutas y netas; regalías; dividendos e inversiones. Se prueba el supuesto de que la privatización de la empresa no era necesaria financieramente y que sí hay sacrificio de renta a favor de los inversionistas, sin mayores aumentos en inversión y reservas. Esta exploración pregunta cuál fue la razón de la privatización y cuáles sus efectos. En este sentido, contribuye a evaluar proyectos privatizadores similares. ABSTRACT: Colombia is a medium size oil producer and exporter with relatively high costs. Colombia transited from risk sharing contracts to a new version of concessions approved in 2004 and the privatization of part of the state oil company ECOPETROL. This article measures the impact of the concession contracts in terms of increased investments in exploration, production and reserves. The privatization is evaluated considering the increased value of the shares and the distribution of dividends compared with the trajectory of royalties, taxes and total investments. Small increases in production did take place and some reserves were discovered. The experiences of Colombia illustrate the reasons and effects of oil privatization for countries of similar characteristics.

    2009-07-01

    Full Text Available Recent research has increasingly questioned the link between natural resources and violent conflict while stressing the importance of resource-specific context conditions under which internal conflicts become more likely. This paper engages in a systematic analysis of six of these resource-specific conditions comparing 15 African oil and diamond producing countries. Employing a Boolean logic, the results of our analysis indicate that, typically, a conflict-ridden diamond or oil producer is highly dependent on resources, its revenues are hardly spent on distributional policies and the security apparatus and, moreover, it suffers from intercommunal problems in the producing regions. Little income from resources per capita and substantial production of lootable resources in peripheral regions seem to constitute necessary conditions for civil war. Thus, our findings imply that future theoretical models and empirical strategies should integrate the full set of (resource specific context conditions. Efforts to raise a more integrative approach combining quantitative and qualitative research designs seem particularly promising.

    Growing up on a farm and an anthroposophic lifestyle are associated with a lower prevalence of allergic diseases in childhood. It has been suggested that the enhanced exposure to endotoxin is an important protective factor of farm environments. Little is known about exposure to other microbial components on farms and exposure in anthroposophic families. To assess the levels and determinants of bacterial endotoxin, mould beta(1,3)-glucans and fungal extracellular polysaccharides (EPS) in house dust of farm children, Steiner school children and reference children. Mattress and living room dust was collected in the homes of 229 farm children, 122 Steiner children and 60 and 67 of their respective reference children in five European countries. Stable dust was collected as well. All samples were analysed in one central laboratory. Determinants were assessed by questionnaire. Levels of endotoxin, EPS and glucans per gram of house dust in farm homes were 1.2- to 3.2-fold higher than levels in reference homes. For Steiner children, 1.1- to 1.6-fold higher levels were observed compared with their reference children. These differences were consistently found across countries, although mean levels varied considerably. Differences between groups and between countries were also significant after adjustment for home and family characteristics. Farm children are not only consistently exposed to higher levels of endotoxin, but also to higher levels of mould components. Steiner school children may also be exposed to higher levels of microbial agents, but differences with reference children are much less pronounced than for farm children. Further analyses are, however, required to assess the association between exposure to these various microbial agents and allergic and airway diseases in the PARSIFAL population.

  5. Análise de bibliografias antroposóficas de Rudolf Steiner por meio da metodologia de Benthall para religiões implícitas

    Full Text Available This paper aims to discuss anthroposophy, which does not consider itself as a form of religion, but seems to suit some definitions of religion and spirituality prevailing within the academic studies of religion. Using Benthall’s methodology of analysis, it seeks to verify how far anthroposophy would deny its religious dimension, but nevertheless acts socially as a religion, which would characterize it as an implicit religion. Of the nineteen categories of analysis, fifteen were found distributed in the books we surveyed. This case is an example of the decline of the influence of religion in cultural spheres and can be seen as a possible pursuit for social legitimacy in response to a secular society, which treats knowledge derived from religious fields with suspicion.

    Full Text Available The aim of the present study was to cross-culturally adapt and validate the Spanish version of the Performance Enhancement Attitude Scale (PEAS. A cross-sectional multi-sample survey with 17 independent datasets was carried out. Cross-cultural adaptation of the PEAS into Spanish was conducted through forward/backward translations, consensus panels and comparative analyses of known-groups to establish evidence for its reliability and validity. Weighted Kappa coefficients with quadratic weighting were used to assess the reliability of each item, with Cronbach’s internal consistency coefficients for overall scale’s reliability and Spearman’s correlation coefficient for test–retest reliability over a one-week period. Confirmatory factor analysis (CFA was performed to assess the scale’s structure. Differences between self-admitted doping users and non-users were analysed to verify the PEAS’ construct validity in 8 datasets. Spearman’s correlation coefficient was also used to assess the relationships between the PEAS and self-esteem, self-efficacy and perceived descriptive norm to establish convergent validity. The scale showed satisfactory levels of internal consistency (α = 0.71–0.85, reliability of each item (Kappa values range 0.34-0.64 and temporal stability (r = 0.818; p < 0.001. CFA showed acceptable fit (RMSEA <0.08, mean RMSEA = 0.055; χ2/df < 3, mean χ2/df = 1.89 for all but one samples. As expected, self-admitted doping users showed more positive attitude toward doping than non-users. Significant and strong negative relationship was found between PEAS and self-efficacy; weak negative correlation with self-esteem and and positive correlation with perceived descriptive norm. The Spanish version of PEAS showed satisfactory psychometric properties. Considerations for application and improvement are outlined.

    Full Text Available The present study aims at evaluating the extent to which the international increase in petroleum price per barrel impacted the profitability of the Transportes Aéreos Marília S.A. (TAM airlines. The context of civil aviation is explored in the case study methodology, including DuPont Method and simple linear regression for the 2001-2006 period. The study attempts to falsify the hypothesis of no relationship between the increase in petroleum price per barrel and profitability. Apparently, the price of a barrel of petroleum influences TAM¿s ROA, ROE, Cost of Assets and Services, Operational Budget, and Net Profit, especially on quarterly bases (significance level: p < .05.

    Full Text Available One of the most widely used physico-chemical characterizations of hydrocarbon mixtures is the determination of their boiling point distribution. Knowledge of the boiling range of crude oils and petroleum products is essential to ensure the correct specification of final products and to control refinery processes. Simulated distillation, a GC based process, has been playing this role for the past decades in the petroleum industry. The main purpose of this work is to show the fundamentals of this technique as well as its present trends.

Los resultados empíricos evidencian un alto grado de persistencia y la presencia de efectos asimétricos en la volatilidad. Aunque la prueba de predicción sesgada muestra que el modelo IGARCH proporciona el mejor ajuste para recoger la persistencia infinita de los choques en la volatilidad, estos hallazgos no son sustentados por las robustas funciones de pérdidas y la prueba estadística de Diebold-Mariano, debido a que los modelos GARCH y EGARCH proporcionan mejores predicciones de la volatilidad fuera de muestra para los horizontes de 1 y 5 días.

    Full Text Available La arquitectura residencial tradicional de Maracaibo ha devenido en la memoria colectiva del venezolano en símbolo de identidad y en una suerte de imagen cultural perdurable. Arquetipo considerado por los locales como modelo de su arquitectura colonial, en el ámbito académico se entiende como ejemplo del modernismo del siglo XIX. Este artículo tiene como objetivo argumentar que fue en el marco de la coyuntura de la explotación petrolera del siglo XX y durante el período gubernamental de Vicencio Pérez Soto, presidente del Estado Zulia (1926-1936, cuando se generaron las condiciones económicas y políticas que viabilizaron, a través de las ordenanzas, la imagen que hoy se reconoce de su arquitectura tradicional. En este trabajo se aplicó el método histórico-urbano, dado su enfoque interdisciplinario, que permite alcanzar la rigurosidad procedimental del uso de fuentes escritas de la mano de las operaciones propias del análisis urbano.

To do this, the fundamentals of the Chavista economic model are examined, analyzing the policies and reforms that have tried to reverse the structural problems of the Venezuelan economy. The emphasis on redistribution and social spending measures is the key in the popular legitimacy of successive governments. Then, it is described the importance of oil for the development of such policies, crucial element for the country’s growth and survival of the implanted model.

    Full Text Available Este artículo aborda un punto específico de una investigación que se interesa por las representaciones en torno a las desigualdades de clase y género en Comodoro Rivadavia, una ciudad petrolera de la Patagonia Argentina. Particularmente, nos interrogamos por la construcción de un grupo de establecidos locales que desprecia a los trabajadores petroleros y sus familias por al considerarlos “negros con plata”, en un contexto de muldimensionalidad de las desigualdades sociales signada por el desacople entre capital económico y capital cultural. Luego de presentar el problema de investigación y sus actores junto al abordaje metodológico, avanzamos hacia una posible definición de la clase media comodorense desde un punto de vista relacional y situado que exige pensar nuevas categorías explicativas. Sostendremos que se trata de una clase en conformación a partir de atributos móviles que, en tanto recursos de distinción cultural –sedimentados moralmente-, funcionan siempre que puedan mostrarse y ponerse en acción frente a la amenaza de pérdida de la hegemonía que representan los trabajadores petroleros y sus familias, que ven incrementados su capital económico y sus posibilidades de consumo a partir de altos salarios.

We conducted a descriptive and quantitative research, with ninety companies. In obtaining the data, we used a closed questionnaire with five-point Likert scale, which were analyzed with the technique of Middle Ranking (RM. As for the results of the respondent companies, 53.3% are in the metropolitan area and 46.7% of the capital. More than 98% had up to three partners, and educational level of 54% of these were high school. Only 3.3% of them had no employees, and around 61% had between 2 and 5 employees. More than 60% reported annual revenues of up to R$ 240,000.00, and almost 68% joined the national simple. Approximately 32% of them were active between 2 and 5 years, and 10% had more than 15 years of existence. We did not identify a specific stage of the CVO of these companies, and much was in transition stages. Thus, we can be assumed that these companies are seeking improvements, market positioning, or overcoming some initial stage steps to achieve more stable CVO.

    1991-03-01

    Full Text Available Una sobre presión en una tubería puede ser tal que se presente una falla por inestabilidad plástica. Para cuando se encuentra una discontinuidad la presión de falla se puede reducir ostensiblemente en especial cuando se tienen fenómenos de fragilidad lo cual no es extraño en uniones soldadas. Las discontinuidades pueden provenir del material, como son las deslaminaciones, o generadas en procesos de soldadura como son inclusiones de escoria y porosidades. Con un tiempo prolongado de servicio una falta de penetración en una soldadura puede producir fenómenos de corrosión por estancamiento reduciéndose la sección resistente hasta obtenerse una condición crítica de falla por fractura. En este trabajo en primer término se presentan conceptos teóricos de falla por inestabilidad plástica en recipientes a presión de pared delgada los cuales son confrontados con los resultados de modelo experimental de laboratorio y en segundo término mediante conceptos de mecánica de fractura se presenta la condición de falla para cuando se cuenta con la presencia de un defecto tipo grieta. Con un modelo de tubería de aluminio se muestra que con una presión fluctuante baja una grieta puede crecer a un tamaño crítico de falla después de un determinado número de ciclos de presión.

Como elas se apropriam do espaço da cidade? O que percebem ao observar a geografia local? As crianças aprendem interagindo com o meio cultural e social em que vivem, quando a escola utiliza a cidade como um grande laboratório de pesquisa para observação e investigação das imagens, está contribuindo para a aprendizagem de conceitos representados no dia-a-dia onde espaço e culturas se entrecruzam nas mais variadas linguagens revelando as características do cotidiano. Essa ação confere credibilidade a uma criança capaz, curiosa, que experimenta o mundo, que é competente e ativa, portanto, alguém que não é somente consumidor de cultura e de valores, mas que com suas idas e vindas pela cidade se torna responsável pela produção e preservação do espaço urbano.Understanding the city from what children show us by the way they see with their photographic eyes, makes it an object of study in this work, questions like: What kind of images call the children’s attention? How do children appropriate the space of a city? What do children notice by observing the local geography? Children learn by interecting whith the cultural and social environment they live in. When the school uses the city as a big research laboratory for observation and investigation of the images, it is contributing for the learning of concepts represented in a day-to-day routine where spaces and culture working together meet themselves in a society in a variety of languages, revealing the characteristics of the time people are living in the city. Acting this way we are giving credibility to a child who has many different abilities and is curious to experience a world that is competent and active, therefore this child is somebody who does not only see culture as a consumer, but by living in the city becomes a responsability for the production and preservation of the urban space.

    Les bâtiments qui ont écrit l’histoire de l’architecture moderne vivent une période décisive: souffrant de nombreux maux dus à leurs âges, d’une méconnaissance, et parfois même d’une certaine impopularité, les menaces sont de plus en plus concrètes: d’une transformation normative et inadaptée jusqu’à la démolition.

Le vieillissement et le pragmatisme quotidien transformant l’édifice, les qualités qui l’ont placé au statut qu’on lui a reconnu ne sont presque plus perceptibles. Pourtant, ces édifices recèlent un grand potentiel; pour les maîtres d’ouvrage au bénéfice d’un bien valorisé, exploité et emblématique d’une part; pour la société enrichissant son patrimoine culturel d’autre part; finalement pour les architectes comme moyen de connaissance, source d’inspiration et ressource professionnelle.

  8. Produção audiovisual no contexto da educação ambiental exigida no licenciamento de petróleo e gás no Estado do Rio de Janeiro

    Directory of Open Access Journals (Sweden)

    Rafael Nogueira Costa

    2016-04-01

    Full Text Available The purpose of this article is to discuss the audiovisual production as an activity to identify the “environmental impacts”, in environmental education in the context of petrol and gas Brazilian licensing process. The question is: Can collective film production be an instrument to express the notion of “environmental impact” of which the social groups belong to? Such a question is answered by reading the documentaries aimed at strengthening local social struggles. Thirty documentaries produced in 2007 were analyzed in ten counties located on the coast of Rio de Janeiro. It shows that the aesthetic form of the documentaries, the search for the look of “affected” and, above all, the direction of the camera reveal nuances of how the groups understand the “environmental impacts” of the economic development process, contributing to further discussions regarding the local implementation of environmental policy, for example, democratic and participatory territorial management. The study concludes pointing out that the production of documentaries as social participation instrument in this case seem to have punctual and temporary effects.

    Full Text Available Oil companies have a long history of cooperative arrangements. The formation of consortia for participation in projects of exploration and production is a common practice and has been seen in Brazil since 1999, when the oil sector was opened to foreign companies. The purpose of this article is to analyze the participation of foreign companies and consortia formed by companies in the bidding for exploratory blocks conducted by the Brazilian agency of oil, natural gas and biofuel [ANP]. The methodology employed is qualitative, supplemented by quantitative analysis, used to verify the existence of correlation between the shares of foreign companies and consortia and two specific variables: Brazil risk and oil prices on the international market. The findings, from a neoinstitutional perspective, point to the conformation of the Brazilian model to international standards in this economic segment, the participation of a large number of companies in the opening process, highlighting the role of Petrobras in the bid rounds, and the formation of a predominant partnership between Petrobras and Petrogal.

    El Servicio Geológico de los Estados Unidos (USGS, por sus siglas en inglés) completó recientemente un estudio evaluativo de recursos potenciales de petróleo y gas en 130 provincias de petróleo seleccionadas en diferentes partes del mundo (USGS, 2000). De estas 130 provincias, 23 se encuentran en Suramérica, Centroamérica, y la región del Caribe (fig. 1). El estudio comprendió desde las provincias de petróleo establecidas con un largo historial de producción, como la Cuenca de Maracaibo, hasta las provincias fronterizas de poca o ninguna producción, como la Cuenca de Guyana-Suriname. No todas las provincias con historial de producción o con potencial de producción fueron evaluadas en el Estudio Evaluativo USGS 2000. Al presente, el USGS está evaluando muchas de las provincias restantes de petróleo y gas, en Centro y Suramérica. En cada provincia hemos (1) definido geológicamente el total de los sistemas de petróleo, (2) definido las unidades evaluadas que forman parte de todos los sistemas de petróleo, y (3) evaluado el volumen potencial de petróleo y gas convencional en cada unidad evaluada. Definimos un total de 26 sistemas de petróleo y 55 unidades evaluadas en las 23 provincias

    Full Text Available The succession process is an important moment in the organizations’ life cycle, particularly in family companies, because according to the way the process is led, the results may represent a competitive advantage or rupture / discontinuity in their life cycle. In this paper we discuss the structural and dynamic characteristics of small family companies, trying to point out elements of analysis that were ignored in the organizational studies based in the Brazilian reality. People understand that in the structure and the dynamic of family companies we can find explanatory elements to the Brazilian family companies longevity. The empirical study was carried out in small Brazilian family companies that work with the retail trade activity in liquefied petroleum gas. Secondary data were used, to identify the sample companies, and also primary data, which were collected by interview technique and analyzed by the techniques of content analysis and discourse analysis. We conclude that the small Brazilian family company longevity is linked to the competitiveness levels expansion which depends on an organizational structure supported by systemic thought and understanding of the organizational dynamic that bind family and company in the same dimension.

  1. Evaluation of radiation protection in the use of radioactive tracers in the oil industry; Avaliação da proteção radiológica no uso de traçadores radioativos na indústria de petróleo

    Radioactive tracers have been widely used in the industry to optimize processes, improve product quality, save energy and reduce pollution. The petroleum industry uses sources for radioactive tracers in solid, liquid and gaseous forms to investigate or track the movement of other materials into pipes of inaccessible lines, such as, {sup 3}H, {sup 82}Br, {sup 131}I, {sup 85}Kr, {sup 41}Ar, {sup 14}C, {sup 24}Na, {sup 192}Ir , etc. The work presents the application of radioactive tracers in the area of oil and gas industry and carries out an evaluation of the radiological risk, the doses of radiation, the specific radiological protection procedures, safety and radiological emergency to be followed. It was observed that radiological risks in the use of radioactive tracers involve three aspects: external dose, external contamination and internal contamination. Most of the time the risk of radiation related to the external dose is very low because unsealed radioactive sources have low activity and exposure times are very low during handling. External and internal contaminations appear due to the use of open sources that allow direct contact and even inhalation or ingestion of radioactive material. It was identified that there is no specific Brazilian regulation for radiation protection in radioactive tracers, and the recommendations of the International Atomic Energy Agency - IAEA should be used.

    This work presents a methodology for predicting concentric and eccentric scales in pipelines used in the offshore oil industry. The approximation is based on the principles of gamma densitometry and artificial neural networks. A preliminary study model was developed to define the compositions of the duct and scale. In order to do so, the influence of pipeline transmission with four different types of steel used in oil platforms was evaluated, as well as the influence of the main inorganic deposit formations. The divergence of the radioactive source was also considered in this evaluation, with collimation openings of 2 mm to 7 mm, with steps of 2.5 mm. After defining the composition of the duct and scale, a measurement geometry was defined by means of the MCNP-X code to calculate the scale thickness by means of analytical equations, independent of the fluids present in the duct (salt water, gas and oil). The representative geometry uses a duct composed of iron, with inorganic scale formed by barium sulfate (BaSO{sub 4}). Concentric scale models were simulated and the data obtained were used for training and validation of an artificial neural network, as well as eccentric scale models. The simulated detection system consisted of a narrow-beam geometry with a 2 mm collimation aperture, comprising a gamma ray source ({sup 137}Cs) and 2 x 2 “NaI (Tl) sensors suitably positioned around the duct-scale-fluid system for calculation of the scale thickness considering the transmitted beam and the scattered beam. Compton scattering was considered in cases of eccentric scale to aid in the determination and location of maximum scale thicknesses. The theoretical models were developed using the mathematical code MCNP-X and used for training, testing and validation of artificial neural networks. The proposed methodology was able to predict the concentric and eccentric scale thicknesses with satisfactory results for these two types of inorganic formations. (author)

    Full Text Available The aim of this paper is to discuss the application of oil royalties in biodiversity conservation in Brazil as part of promoting sustainable development. The loss of species and reduction of genetic variation are direct and/or indirect consequences of human actions such as deforestation, urban sprawl, burning fossil fuels, among others. Starting from the idea that the royalties make up a financial compensation whose genesis is the promotion of intergenerational justice, we performed an analysis of the legal framework in place to determine the compatibility of these resources with the protection of biodiversity. We notice that there is a gap in ownership of intergenerational perspective, constitutionally established, both along the legislative process and practice of related public policy. Even with the various options for the application of oil royalties, we conclude by defending its application in biodiversity conservation as heritage for future generations.

    Pipelines are interconnected ducts systems used to transport large quantities of petroleum and its by-products, are more economical, eliminate the need for stocks and, in addition, present great safety in operation minimizing the possibility of loss or theft. In many cases, especially in the petrochemical industry, the same transport line is used to carry more than one type of product (poliduct), such as: gasoline, diesel and kerosene. In the operation of a poliduct there is a sequence of products to be transported and during the exchange of the product, there are still fractions of volume of the previous product thus occurring contaminations. The traditional solution is to discard all this volume; however it is important to identify precisely this region in order to reduce the costs of reprocessing and treatment of discarded products. This work presents a methodology to evaluate the sensitivity of the gamma densitometry technique in the precise identification of the interface region by optimizing the transportation of petroleum by - products into polyducts. The study considered geometry composed of a source of {sup 137}Cs, an acrylic tubing measuring 8.0 cm in diameter and a 1 x 1 “NaI (T1) detector, a position diametrically opposed to a radiation source to measure the transmitted beam. Using computational simulations using the Monte Carlo method with the MCNPX code, measurement geometry with the highest sensitivity for the calculation of volume fractions was proposed. The pertinent technical data (dimensions and materials) to perform the simulation of the detectors were based on information obtained from the gammagraphy technique. The study had a theoretical validation through analytical equations and the results show that it is possible to identify the interface region with an accuracy of 1%. (author)

    Full Text Available Upper Cretaceous pelitic rocks generate most of the oil reserves in Colombia. In Del Magdalena Upper Valley (MUV, the existenceof good quality outcrops and thermal evolution levels that vary from immaturity to the end of the oil generation “window” makes it one of themost appropriate regions for the study of primary migration and generation of oil in Upper Cretaceous. The main objectives of this work wereto study the organic facies of La Luna Formation in an outcrop section called Riacho Bambuca (Bambuca Creek, determine the oil generationpotential and characterize the paleoenvironment. For this research, 24 samples were used in palynofacies analysis (characterization ofthe kerogen components assembly and in organic geochemistry analysis (Total Organic Carbon – TOC analysis and Rock-Eval pyrolysis,provided by Colombia Oil Institute – ECOPETROL. The palynofacies analysis included the use of microscopy techniques (transmitted whitelight and incident blue light. Furthermore, a Spore Coloration Index (SCI analysis was made in order to determine the thermal maturationstage. The studied material was composed mainly of an amorphous organic substance, with its fluorescent coloration varying from yellow tobright orange. The palynomorph group is represented by spore morph and dinoflagellate cysts. The ligneous material are present in very lowpercentages; they are mainly opaque phytoclasts. The results of geochemical analysis showed TOC contents ranging from medium to high,excellent potential for the generation of hydrocarbons (PG > 4 mg HC/g of rock, hydrogen index ranging from 329 to 589 mg HC/g, andlow values of oxygen index, characterizing type II kerogen. The low degree of thermal maturation was determined by Spore Coloration Indexvalues ranging from 2,5 to 3,0, Tmax values below 440°C and Hydrocarbon Production Index inferior to 0,2. According to the organic faciesdata, La Luna Formation deposited in a marine environment with facies from disoxic-anoxic distal shelf and suboxic-oxic distal basin; therewas kerogen of excellent quality, and its quantity was adequate for the generation of oil.Keywords: Organic facies; La Luna Formation; Cretaceous; Colombia

    Full Text Available The addition of calcium carbonate in drilling fluids is a common practice during the oil well drilling process. These additives commonly called bridging agents help in the formation of a layer of fine particles and low permeability called filter cake. The formation of the filter cake occurs on the surface of the walls of the well, helping to reduce the inflow of drilling fluid into the reservoir. For describing the flow in a deformable porous media, the constitutive equation for determining the permeability of the porous medium is necessary, making possible to simulate the operation. In this context, this study determined the relationship between porosity and permeability of porous media consisting of calcium carbonates 2-44 μm. The porosity distribution in the sediment was determined using the gamma-ray attenuationtechnique. The results showed significant differences when compared with the values estimated by the correlation proposed by Kozeny-Carman.

    Radiotracers have been widely used in various sectors of science and engineering in order to investigate the transport in porous media due to their easy detection, the use of very low mass and with nanotechnology allowing simple modifications of their properties and their surfaces Via coating or chemical alteration, and can effectively replace conventional radioactive organic markers, which usually decompose. With this in mind, four methods of silica-coated gold nanoparticles were produced for use as tracers in porous media. Gold beads were produced from HAuCl{sub 4} solutions. 3H{sub 2}O and as reducing agents, gamma irradiation (S0), sodium oleate (S1); Sodium citrate - C{sub 6}H{sub 5}Na{sub 3}O{sub 7}.2H{sub 2}O (S2 + PVP); And C{sub 6}H{sub 5}Na{sub 3}O{sub 7}.2H{sub 2}O plus gamma irradiation (S3). Sample S1 was prepared by mixing an aqueous solution of HAuCl{sub 4}.3H{sub 2}O (2 x 10{sup -3} mol L{sup -1}) with isopropyl alcohol (C{sub 3}H{sub 8}O, neat) plus Polyvinylpilorridone (PVP, stabilizing agent) followed by gamma irradiation (30 kGy dose); Sample S1 was prepared by mixing an aqueous solution of HAuCl{sub 4} 3H{sub 2}O (0.1 mol L{sup -1}) plus sodium oleate (0,05 mol L{sup -1}), followed by heating at 80°C for 10 min; For sample S2 + PVP, an aqueous solution of HAuCl{sub 4} was mixed. 3H{sub 2}O (0.1 mol L{sup -1}) and sodium citrate (0.034 mol L{sup -1}) followed by heating at 90°C; and finally, sample S3 was prepared by mixing an aqueous solution of HAuCl{sub 4}.3H{sub 2}O (0.1 mol L{sup -1}) plus sodium citrate (0.034 mol L{sup -1}) followed by gamma irradiation (30 kGy). The gold nanospheres were confirmed by ultraviolet analysis, presenting wavelengths between 514 and 530 nm. The gold beads were coated with a silica layer via sol-gel reaction using solutions of ethanol (pure) or isopropyl alcohol with tetraethyl ortho-tosylate (TEOS, 98%) and ammonium hydroxide (NH{sub 4}OH, 28.3%). Physical interaction (control of size distribution and coating thickness) were examined by transmission electron microscopy analysis and discussed to test the efficiency of this NP as a tracer use in laboratory scale porous media. Other tracers such as tritiated solution and NaCl were used for a reference test for the tracer developed in this work. (author)

    Petroleum is generated from the transformation of the organic matter accumulated in the sedimentary rocks, when submitted to the appropriate thermal conditions and is found both in the marine and terrestrial subsoil. In order to determine the volume of petroleum existing in a deposit oil wells technique is used which consists of a set of operations in which are recorded as a function of the depth, some characteristics of the geological layers along the well, such as permeability and porosity with the use of radioactive sources. The sources used in this practice belong to category 3, among five categories of categorization considered dangerous and in case of accident represents a higher level of radiological risk. The present work aims to present the main requirements of radiological safety and physical security to be applied in the licensing of an oil well profiling plant. In this work, the author supported the bibliographical review, which consisted in the collection of the essential literature related to the theme. The literature is composed of theoretical references published in books, theses, Brazilian norms, Mozambican laws, IAEA manuals and some published on the internet. The methodology used in this work was the bibliographical review with the objective of obtaining information on the formation of oil, oil well profiling concept, the radioactive sources used in this practice, for information on the main applicable radiological security and safety requirements radioactive sources and oil well profiling facilities. The inventory of radioactive sources, the use of shielding and the smear tests in radioactive sources are technical requirements that integrate the radiological safety and physical safety that must be followed by the licensees of the oil well profiling.

    Full Text Available A principal característica dos aços inoxidáveis duplex é o equilíbrio entre as fases austenita e ferrita, que garantem ao material melhores índices de resistências à corrosão e mecânica. No entanto, durante o processo de soldagem, ocorrem modificações estruturais, principalmente no balanço destas fases. Este desbalanceamento, em função dos níveis de solicitações mecânicas, pode levar tais regiões soldadas ao colapso. No intuito de minimizar o desequilíbrio das fases na região soldada, diversas técnicas são utilizadas, tais como inserção de metal de adição com elementos austenitizantes, uso de gás de proteção com nitrogênio ou, em outros casos, controle pós soldagem. Buscou-se identificar o verdadeiro efeito dos parâmetros de soldagem e do tratamento térmico especificado pela literatura em situações de campo. Através de uma avaliação temporal, observando uma linha de produção de tubulação flexível de aço inoxidável duplex UNS 32304 durante três anos, utilizando-se de procedimentos convencionais de soldagem com e sem a utilização de tratamento térmico foram observadas as falhas por fratura na zona termicamente afetada (ZTA. Foi utilizado um indutor localizado para o tratamento térmico, gerando um intenso fluxo de calor que promoveu temperaturas da ordem de 1000 ºC a altíssimas taxas de subida e descida, conforme estabelecem algumas literaturas.The main characteristic of duplex stainless steels is the balance between ferrite and austenite phases, wich ensures to such material the best levels of corrosion and mechanical resistance. However, during the welding process, structural modifications occur, especially with regard to the balance of these phases. This imbalance, depending on the levels of mechanical stress, may lead welded regions to collapse. In order to minimize the imbalance of the phases in the welded steel, several techniques are used, such as the insertion of filler metal with austenite formers, the use of shielding gas with nitrogen or, in other cases, the post weld control. It was tried to identify the true effect of welding parameters and heat treatment specified by the literature in field situations. Through an temporal evaluation, watching a production line of flexible pipes of UNS 32304 duplex stainless steel during three years, using conventional welding procedures with and without the use of heat treatment, failures were observed by a fracture in the heat affected zone (HZA. It was used a local inductor to the heat treatment, generating an intense heat flow that caused temperatures of about 1000 °C at very high rate of ascent and descent, as set for some literatures.

    The work establishes radiation protection and safety requirements for NORM in oil and gas installations, enabling the National Atomic Energy Agency to draw up regulations on NORM. A bibliographic review and measurement of oil sludge activity concentrations was carried out to reach the objective. Significant amounts of NORM originating from reservoir rock are encountered during production, maintenance and decommissioning. The oil and gas industry operates in all climates and environments including the most arduous conditions and is continually challenged to achieve high operating efficiency while maintaining a high standard of safety and control - this includes the need to maintain control over exposure as well as protecting the public and the environment through the proper management of tailings that may be radiologically and chemically hazardous. The main objective of this work was not only to present the main radiological protection and safety requirements for NORM in oil and gas installations, but also to guide the competent governmental authorities of the Republic of Mozambique, that the installation of a radiometry laboratory and elaboration of NORM regulations involve a great control of radiological safety. The regulatory authority is responsible for authorizing facilities for the storage of radioactive waste, including the storage of contaminated tailings. It is recommended that studies of this kind be made to analyze the concentration of naturally occurring radioisotope activity. (author)

    Full Text Available The Guanabara Bay is the second bigger bay of the Brazilian coast. The bay is oneof most beautiful of the world and shelters an ample and protected natural environment,preponderant factor for the development of the region. Due the pollution of this ecosys-tem, today, the bay represents an important focus of environmental interest. In order todeterminate the preservation degree of the organic components of bottom sediments from Guanabara Bay, ninety-two samples were collected from these sediments, however, pre-liminarily, twenty-five samples were analyzed. These twenty-five samples were submittedto techniques of organic geochemistry (Total Organic Carbon - TOC and Rock-Evalpyrolysis to determinate the amount and quality of the organic matter, and microscopy(transmitted white light and reflected ultraviolet light. The TOC values of the twenty-fivesamples range from 0.04 to 6.1% indicating the high preservation degree of the organicmatter. The Rock- Eval pyrolysis data show Hydrogen Index (HI values from 25 to 249mg HC/gCOT; S1 values ranges from 0,02 to 5,6 mg HC/gR; Production Index (PI rise up0,5. The results of the microscopy investigation showed that occur a predominance ofamorphous organic matte (AOM over the palynomorphs and phytoclasts. The liptiniticmaterial showed a light yellow-greenish yellow fluorescence color. The percentages ofAOM, the TOC values and fluorescence color indicate a high degree of preservation of theorganic matter. The integration of the results from organic geochemistry and microscopytechniques indicate that the sediments of the Baía de Guanabara present very high hydro-carbon pollution, deposited in dysoxic-anoxic environment.

    Poly (ethylene terephthalate) recycled (PETR), in the form of flakes resulting colorless soda bottles from landfills in the State of Paraíba, was doped with a styrenic-acrylic-epoxy multifunctional oligomer (Joncryl POLYAD PR 002) marketed as extender chain for condensation polymers. To evaluate the effect of the same increase in the molar mass of the polymer, the PETR was processed in the absence and presence of chain extender (1%, 3% and 5% by mass) in internal mixer Haake Rheomix with roller type rotors. The molar masses were estimated from measurements of torque, and temperature. According to the results it was evident that the additive offset the loss of molecular weight during the processing of PETR and this effect was affected by the level of additive, which also changed the crystallization of the PETR as data from X-ray diffractometry (XRD) and differential scanning calorimetry (DSC).

    Highlights: • A novel natural fiber reinforced recycled poly (ethylene terephthalate) composite was prepared. • Mechanical performance and thermal behavior of the composites were investigated. • Composites with improved toughness and strength were achieved. - Abstract: Development of a recycled poly (ethylene terephthalate) (PETr) reinforced with surface treated date palm leaf fiber (DPLF) composites with enhanced mechanical properties have been studied. Surface modified date palm leaf fiber reinforced PETr composites were prepared using twin-screw extruder followed by injection molding and the influence of the DPLF content on the mechanical and thermal behavior of the PETr matrix was evaluated. Upon the addition of fibers, remarkable enhancements in the mechanical properties of the composites were observed. Scanning electron microscopy (SEM) images taken from DPLF fibers showed significant enhancements in the fiber’s surface topography after the surface treatment process. Dynamic mechanical analysis (DMA) indicated that the addition of DPLF to PETr matrix increased the composites toughness. The crystallization behavior of the samples, analyzed by differential scanning calorimetry (DSC) indicated an increase in the onset crystallization temperature and showed a higher degree of crystallinity of the composites as compared to PETr, demonstrating that DPLF particles could act as nucleating agents. The results point to the composite’s potential in wider indoor applications

Six basic Adlerian positions on human behavior, including Rudolf Dreikurs' "four goals of misbehavior," are interpreted as a primitive statement of operant principles. Applied techniques long used by Individual Psychology practitioners strongly resemble interventions that applied behavior analysts have developed by more systematic means.
