Full Text Available Este artigo analisa alguns aspectos do Tesouro descoberto no rio Amazonas, obra composta pelo padre João Daniel (1722-1776, missionário jesuíta no Estado do Maranhão e Grão-Pará entre 1741 e 1757, desterrado para Lisboa dois anos antes do banimento da Companhia de Jesus da América portuguesa. A obra, registro singular da Amazônia de meados do século XVIII, oferece um compêndio das riquezas e potencialidades da região. Sobretudo, apresenta um projeto para a colonização crítico ao modelo então em vigor e que se apresenta como um conjunto integrado que considera as condições ambientais, a técnica e as relações sociais na organização da sociedade local. Ao colocar no centro de seu projeto a questão do trabalho, João Daniel recupera, como metáfora, a idéia - marcante na literatura missionária do século XVII e praticamente abandonada no século XVIII - da Amazônia como paraíso terrestre.The article analyzes certain aspects of "Tesouro descoberto no rio Amazonas" (Treasure discovered on the Amazon River, written by João Daniel (1722-76 during his time in the State of Maranhão e Grão-Pará as a Jesuit missionary between 1741 and 1757; the priest was banished to Lisbon two years before the Company of Jesus was expelled from Portuguese America.

King João II of Portugal “O Principe Perfeito” and the Jews (1481-1495

Soyer, François

2009-06-01

Full Text Available King João II (1481-1495 is chiefly remembered in Portuguese historiography as the first “modern” King of Portugal and a monarch who vigorously worked to restore the status of the Portuguese Crown, weakened during the reign of his father Afonso V (1438-1481. In Jewish historiography, however, João II has become infamous for his persecution of the Jews who came to Portugal after their expulsion from Castile in 1492 as well as his order to seize Jewish children from their parents so that they could be converted to Christianity and sent to colonize the Island of São Tomé. Using Hebrew, Spanish and Portuguese sources, this article examines in detail the nature of the relations that existed between João II and the Jews, both those who were natives of Portugal as well as the Jewish exiles from Castile.

El rey João II es recordado en la historiografía portuguesa principalmente como el primer rey «moderno» de Portugal, y un monarca que trabajó enérgicamente para restaurar el estatus de la Corona, debilitada durante el reinado de su padre Afonso V (1438-1481. Sin embargo, la historiografía judía ha construido una imagen del rey como infame por su persecución de los judíos expulsos llegados de Castilla en 1492, así como por la orden de sustracción de niños judíos a sus progenitores para usarlos en la colonización de la isla de São Tomé. Mediante el uso de fuentes hebreas, hispánicas y portuguesas, este artículo examina de forma detallada la naturaleza de las relaciones existentes entre João II y los judíos, tanto de los que eran nativos de Portugal, como de los castellanos exiliados.

The many arts in Santiago, by João Moreira Salles

2012-05-01

Full Text Available This article discusses the documentary Santiago, by João Moreira Salles, exploring the many arts of the main character Santiago. Besides being very rich in its autobiographic approach, the film allows us to establish some connections with literature and some characters of Borges and Flaubert, as it relates to performance and documentary theories. Santiago, disguised as a butler for over four decades, began to accumulate delusions. While working at the residence of the Moreira Salles, he typed 30,000 cards, classified and cataloged his own story and the “history of great men”. His notes are the record of his passage through Literature and History. The film by João Moreira Salles ensures Santiago’s posterity, in the same way that reports of Dante and the creations and inventions of Borges ensure the existence of their characters. Santiago, as a Flaubert’s copyist, lives and is reinvented on the screen through his testimony, memory, art and through the auto fictional documentary by Salles.

Interaction of trimebutine and Jo-1196 (fedotozine) with opioid receptors in the canine ileum

Energy Technology Data Exchange (ETDEWEB)

Allescher, H.D.; Ahmad, S.; Classen, M.; Daniel, E.E. (Technical Univ., Munich, (West Germany))

Receptor binding of the opioid receptor antagonist, ({sup 3}H)diprenorphine, which has a similar affinity to the various opioid receptor subtypes, was characterized in subcellular fractions derived from either longitudinal or circular smooth muscle of the canine small intestine with their plexuses (myenteric plexus and deep muscular plexus, respectively) attached. The distribution of opioid binding activity showed a good correlation in the different fractions with the binding of the neuronal marker ({sup 3}H)saxitoxin but no correlation to the smooth muscle plasma membrane marker 5'-nucleotidase. The saturation data (Kd = 0.12 +/- 0.04 nM and maximum binding = 400 +/- 20 fmol/mg) and the data from kinetic experiments (Kd = 0.08 nmol) in the myenteric plexus were in good agreement with results obtained previously from the circular muscle/deep muscular plexus preparation. Competition experiments using selective drugs for mu (morphiceptin-analog (N-MePhe3-D-Pro4)-morphiceptin), delta (D-Pen2,5-enkephalin) and kappa (dynorphin 1-13, U50488-H) ligands showed the existence of all three receptor subtypes. The existence of kappa receptors was confirmed in saturation experiments using ({sup 3}H) ethylketocycloazocine as labeled ligand. Two putative opioid agonists, with effects on gastrointestinal motility, trimebutine and JO-1196 (fedotozin), were also examined. Trimebutine (Ki = 0.18 microM), Des-Met-trimebutine (Ki = 0.72 microM) and Jo-1196 (Ki = 0.19 microM) displaced specific opiate binding. The relative affinity for the opioid receptor subtypes was mu = 0.44, delta = 0.30 and kappa = 0.26 for trimebutine and mu = 0.25, delta = 0.22 and kappa = 0.52 for Jo-1196.

A New Jatropha curcas Variety (JO S2 with Improved Seed Productivity

2014-07-01

Full Text Available One key reason for the failure of Jatropha plantation is the use of non-improved planting materials. We present in this paper a Jatropha variety (JO S2 through selective breeding with much better seed productivity than wild accessions as proven by field trials in Singapore and India. In a single farm trial in Singapore for two years, a comparison was conducted with accessions from China, India, Indonesia and Africa. It was found that all traits studied like seed yield, seed kernel content, seed oil content, fatty acid composition, phosphorus content and PE content differed significantly among and within the wild accessions. Overall, JO S2 was the best performer with the highest seed yield, high oil content and low phosphorus content. On two sites in Tamil Nadu, Southern India, this Jatropha variety produced up to 2.95 ton/ha of dry seeds in the first year and up to 4.25 ton/ha of dry seeds in the second year, much better than the local variety control. We attribute its higher seed productivity to early flowering, better self-branching, more flower/fruiting bunches, more fruits per bunch and importantly, better uniformity among plants. This exemplifies that breeding has improved Jatropha seed productivity which will lead to better economics for Jatropha plantation.

Bridging the Divide between Manual Gating and Bioinformatics with the Bioconductor Package flowFlowJo

John J. Gosink

2009-01-01

Full Text Available In flow cytometry, different cell types are usually selected or “gated” by a series of 1- or 2-dimensional geometric subsets of the measurements made on each cell. This is easily accomplished in commercial flow cytometry packages but it is difficult to work computationally with the results of this process. The ability to retrieve the results and work with both them and the raw data is critical; our experience points to the importance of bioinformatics tools that will allow us to examine gating robustness, combine manual and automated gating, and perform exploratory data analysis. To provide this capability, we have developed a Bioconductor package called flowFlowJo that can import gates defined by the commercial package FlowJo and work with them in a manner consistent with the other flow packages in Bioconductor. We present this package and illustrate some of the ways in which it can be used.

Mishima jo ha kyu

Matteo Casari

2012-01-01

Full Text Available Abstract – IT La grandezza artistica di Mishima si è espressa attraverso una eterogenea gamma di linguaggi tra i quali il teatro – nella drammaturgia ma anche nella saggistica, regia, recitazione e direzione di compagnia – ha avuto un ruolo di primo piano. Al pari di un uomo di scena Mishima inaugura, a partire dagli anni ’50, un processo di attenzione al proprio corpo come possibile, anzi necessario, veicolo di estrinsecazione etico-estetica tanto da poter istituire l’equazione corpo-teatro quale snodo profondo del suo processo creativo. Il corpo sognato e ottenuto da Mishima attraverso l’addestramento nel kendo, in altre arti marziali e nel body building si conformava ad un ideale estetico di matrice greco-classica assai lontano dal corpo teatrale nipponico. Il corpo come luogo di elaborazione e strumento di espressione autentica da realizzare con impegno, però, lo legano profondamente alle esperienze nascenti – tra gli anni ’50 e ’60 – delle avanguardie teatrali giapponesi. La metafora teatrale è spesso usata nella lettura critica del Mishima uomo e artista con accezione deteriore: un personaggio che dà spettacolo di sé con ripetute provocazioni tra le quali il suicidio del 25 novembre 1970 non sarebbe che l’esempio ultimo e più estremo. La costruzione di sé come personaggio, invece, sembrerebbe corrispondere ad una ben più profonda e meditata necessità di comporre la propria vita in una sapiente messa in scena di classica perfezione: i principi della scansione ritmico formale del jo ha kyu, pilastro teorico del teatro no codificato da Zeami tra XIV e XV secolo, offrono un valido modello di riferimento. Abstract – EN Mishima’s artistic greatness has been expressed through a diverse range of languages among wich theater – in dramaturgy as well as in written essays, as a director, performer and in company direction – played a central role.

Gap-filling analysis of the iJO1366 Escherichia coli metabolic network reconstruction for discovery of metabolic functions

Directory of Open Access Journals (Sweden)

Orth Jeffrey D

2012-05-01

Full Text Available Abstract Background The iJO1366 reconstruction of the metabolic network of Escherichia coli is one of the most complete and accurate metabolic reconstructions available for any organism. Still, because our knowledge of even well-studied model organisms such as this one is incomplete, this network reconstruction contains gaps and possible errors. There are a total of 208 blocked metabolites in iJO1366, representing gaps in the network. Results A new model improvement workflow was developed to compare model based phenotypic predictions to experimental data to fill gaps and correct errors. A Keio Collection based dataset of E. coli gene essentiality was obtained from literature data and compared to model predictions. The SMILEY algorithm was then used to predict the most likely missing reactions in the reconstructed network, adding reactions from a KEGG based universal set of metabolic reactions. The feasibility of these putative reactions was determined by comparing updated versions of the model to the experimental dataset, and genes were predicted for the most feasible reactions. Conclusions Numerous improvements to the iJO1366 metabolic reconstruction were suggested by these analyses. Experiments were performed to verify several computational predictions, including a new mechanism for growth on myo-inositol. The other predictions made in this study should be experimentally verifiable by similar means. Validating all of the predictions made here represents a substantial but important undertaking.

David Bowie’s Influence on JoJo’s Bizarre Adventure

Francesco-Alessio Ursini

2017-03-01

Full Text Available This article analyses the influence of David Bowie’s work in JoJo’s Bizarre Adventure, a manga known for its wealth of references to western popular culture. It is argued that David Bowie’s cultural reception can be attested via the presence of three narrative themes featuring in this manga series. The first theme is the exploration of diverse genres and an innovative, genre-defying attitude. The second theme is the use of avant-garde, flamboyant and gender-ambiguous aesthetics for its fictional characters. The third theme is a self-reflexive approach to the creation of fictional characters, intended as an awareness of the temporary, transient nature of their role as reluctant heroes in their own stories.

The Cyto-Dot 4 HM043 kit commercialised by BMD, has replaced the Cyto-Dot HM010 kit that allowed three auto-antibodies detection (anti-Jo-1, anti-M2 and anti-ribosomal protein). Detection of anti-LKM1 auto-antibody was added. These four auto-antibodies have in common only the intracytoplasmic localisation of their respective antigen. The aim of our study was to evaluate this new kit using 104 sera and to compare our results with reference techniques (indirect immunofluorescence IF for anti-M2, anti-ribosomal protein and anti-LKM1, double immunodiffusion ID for anti-Jo-1 and anti-LKM1, western blotting WB for anti-M2) and with Cyto-Dot HM010. The one hundred and four sera were divided into five groups: Group I (n = 12) with anti-Jo-1 detected by ID; Group II (n = 28) with 26 anti-M2 positive by IF and WB, 2 anti-M2 positive only by WB; Group III (n = 10) with anti-ribosomal protein detected by IF 5 of which precipitated by ID; Group IV (n = 32) with anti-LKM1 by IF and ID divided into 18 AIH2 and 14 HCV; Group V (n = 22) consisting of 14 healthy individuals and 8 patients with hypergammaglobulinemia. Results of this study are similar to those of Cyto-Dot HM010 for the three auto-antibodies already in use. Cyto-Dot 4 is a very good anti-LKM1 confirmation method as it is ID.

Anti-Jo-1 and anti-Ro52 autoantibodies are common in patients with myositis, but the mechanisms behind their production are not known. Survival of autoantibody-producing cells is dependent on B-cell-activating factor of the tumour necrosis factor family (BAFF). BAFF levels are elevated in serum of anti-Jo-1-positive myositis patients and are influenced by type-I interferon (IFN). IFN-producing cells and BAFF mRNA expression are present in myositis muscle. We investigated expression of the receptors for BAFF in muscle tissue in relation to anti-Jo-1 and anti-Ro52/anti-Ro60 autoantibodies and type-I IFN markers. Muscle biopsies from 23 patients with myositis selected based on autoantibody profile and 7 healthy controls were investigated for expression of BAFF receptor (BAFF-R), B-cell maturation antigen (BCMA) and transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI). Nineteen samples were assessed for plasma (CD138) and B-cell (CD19) markers. The numbers of positive cells per area were compared with the expression of plasmacytoid dendritic cell (pDC) marker blood dendritic cell antigen-2 (BDCA-2) and IFNα/β-inducible myxovirus resistance-1 protein (MX-1). BAFF-R, BCMA and TACI were expressed in five, seven and seven patients, respectively, and more frequently in anti-Jo-1-positive and/or anti-Ro52/anti-Ro60-positive patients compared to controls and to patients without these autoantibodies (P = BAFF-R: 0.007, BCMA: 0.03 and TACI: 0.07). A local association of receptors with B and plasma cells was confirmed by confocal microscopy. The numbers of CD138-positive and BCMA-positive cells were correlated (r = 0.79; P = 0.001). Expression of BDCA-2 correlated with numbers of CD138-positive cells and marginally with BCMA-positive cells (r = 0.54 and 0.42, respectively; P = 0.04 and 0.06, respectively). There was a borderline correlation between the numbers of positively stained TACI cells and MX-1 areas (r = 0.38, P = 0.08). The expression

The spiritual and identity shifts can be interpreted along these eternal human desires as well. A patchwork of remembering and forgetting, the internal journeys of identity preservation, spontaneous or forced assimilation, tolerance and all kinds of politics-induced human deformations are depicted in the novel. The text traces the roles of the journey defined by Jean Chevalier and Alain Gheerbrant such as the search for justice, peace, immortality and finding the spiritual center. This study examines how the concrete physical journey changes into an internal road determining the evolution of personality.

Full Text Available Arquitectura e industrialización de la construcción en la obra de João Filgueiras Lima – LeléResumenLa industrialización de un edificio requiere un alto rigor técnico en su diseño y producción. En Brasil, la obra del arquitecto João Filgueiras Lima, “Lelé”, se destaca como un ejemplo del proceso de diseño de los edificios industriales, que abarcan todas las etapas de la construcción. Este artículo ofrece la trayectoria tecnológica de Lele y el desarrollo de la producción industrial a través de sus diversas experiencias en las fábricas para el desempeño de los sistemas de construcción. A continuación, se analiza su producción industrializada en el Marco de Apoyo Comunitario de Ribeirão Preto (São Paulo, Brasil, aún poco conocida. Como método se utilizó un estudio de caso único, con múltiples fuentes de evidencia, tales como entrevistas, observación directa y documentos. De los resultados, parece que “Lelé” ha mejorado constantemente sus prácticas de construcción y elementos industrializados utilizados ya que participó en todo el proceso de construcción de edificios. Aunque se hace uso de la producción en masa, obtiene un apropiado método para el contexto en el que se insertan los edificios complejos. Palabras clave: arquitectura brasileña, arquitectura industrial, diseño constructivo, edificio industrial, industria de la construcción, procesos y técnicas de construcción. Architecture and construction’s industrialization in the work of João Filgueiras Lima – LeléAbstractThe industrialization of a building requires high technical rigor in design and production.

In-Born Radio Frequency Identification Devices for Safeguards Use at Gas-Centrifuge Enrichment Plants

International Nuclear Information System (INIS)

Ward, R.; Rosenthal, M.

2009-01-01

Global expansion of nuclear power has made the need for improved safeguards measures at Gas Centrifuge Enrichment Plants (GCEPs) imperative. One technology under consideration for safeguards applications is Radio Frequency Identification Devices (RFIDs). RFIDs have the potential to increase IAEA inspector's efficiency and effectiveness either by reducing the number of inspection visits necessary or by reducing inspection effort at those visits. This study assesses the use of RFIDs as an integral component of the 'Option 4' safeguards approach developed by Bruce Moran, U.S. Nuclear Regulatory Commission (NRC), for a model GCEP [1]. A previous analysis of RFIDs was conducted by Jae Jo, Brookhaven National Laboratory (BNL), which evaluated the effectiveness of an RFID tag applied by the facility operator [2]. This paper presents a similar evaluation carried out in the framework of Jo's paper, but it is predicated on the assumption that the RFID tag is applied by the manufacturer at the birth of the cylinder, rather than by the operator. Relevant diversion scenarios are examined to determine if RFIDs increase the effectiveness and/ or efficiency of safeguards in these scenarios. Conclusions on the benefits offered to inspectors by using in-born RFID tagging are presented.

Writing in the Shadow of “Pride and Prejudice”: Jo Baker’s "Longbourn"

Directory of Open Access Journals (Sweden)

Olivia Murphy

2017-12-01

Full Text Available Jo Baker’s 2013 novel Longbourn explicitly engages with Jane Austen’s Pride and Prejudice, published two centuries earlier. Longbourn’s plot neatly intersects with Austen's original, offering us a glimpse into a world which adaptations of Austen’s novels, and even Austen herself, have long been criticised for ignoring. Baker takes advantage of the freedoms of twenty-first century fiction to bring into the light aspects of Austen’s writing that Regency discretion elided, and Victorian prudery all but annihilated. Longbourn explores with sensitivity and due regard to historicity matters to which Austen could only allude; the horrors of war and military justice, complexities of sexuality that cannot be wholly contained within the sanction of marriage, the effects of the industrial revolution on the countryside and poor alike. If Pride and Prejudice, as Austen ironically opined, was “too light & bright & sparkling”, Longbourn offers us the shading that throws that sparkle into relief, thereby allowing us to view it afresh.

Full Text Available O romance O amor de Pedro por João publicado no Brasil, em 1982, e escrito durante o exílio do escritor brasileiro Tabajara Ruas (1942 é analisado a partir da relação escritor/escrita. Tal correspondência é discutida por um viés que inclui as anotações de pesquisadores, como Avelar, Silverman e Santiago, entre outros. A observação da forma, do estilo e das temáticas empregadas pelo artista aponta para a complexidade de questões referentes à profissão “escritor” em um contexto histórico pleno de cerceamento de liberdades situado entre os anos 1960 e 1980. Além disso, suscita reflexões sobre procedimentos literários experimentais em um meio social em que se ampliaram o grau e o controle da informação, apontando, deste modo, ligações entre a Literatura e a História.

Full Text Available O artigo analisa aspectos econômicos da elite colonial mineira a partir de meados do século XVIII, mediante a investigação empírica da sociedade de São João Del Rei. O comércio em São João assumiu um papel central na liquidez da economia regional, permitindo a formação de grupos hegemônicos no século XIX. Mas há ainda muitas dúvidas sobre quem era essa elite no século XVIII. Com base em pesquisa prosopográfica que reconstrói os caminhos dos homens arrolados por Domingos Nunes Vieira como os mais ricos da capitania de Minas Gerais no ano de 1756, percebemos que a elite mineira que se formou no século XVIII diferia dos padrões mais gerais para a caracterização de grupos hegemônicos em outras regiões do Brasil, no mesmo período

Typography of Jože Plečnik

2013-09-01

Full Text Available ABSTRACTPurpose: This paper focuses on the typographic analysis of a small fairy tale book Makalonca designed by Plečnik, and on the analysis of its two reprints, which were unfortunately found to be inferior to the original design.Methodology/approach: The differences and inconsistencies between the original and the two reprints of Makalonca were studied in details by the means of a comparative analysis.Results: The architecture of Jože Plečnik (1872–1957 is well known throughout Europe, while his graphic design and typography are less known. During the Second World War he made all the decorations, vignettes and initials for the fairy tales and elaborated the graphic design for the book which was published in two different bindings – hardcover and paperback. Two paperback reprints were subsequently published as well, the first one a year after the architect’s death in 1958 and the second one in 1988, commemorating the centenary of the fairytales. In both reprints it was stressed that the graphic design remained the same as it was done by Plečnik. On the contrary, both reprints are deformations of the original. Not only that they are different in the book and layout size and typefaces, one even differs in the type style and type size of the body text. Moreover, there are also many other differences within the rest of the text, thus representing a great loss for the Slovenian cultural heritage.Research limitation: The research was hampered by difficulties in the accessibility and authentication of historical data of printing in Slovenia.Originality/practical implications: This is the first detailed typographic research of a smaller part of Plečnik’s graphic design. The typographic analysis and research results can be of use at the preparation of facsimile or authentic reprints important for our cultural heritage.

We report the first case of non-specific interstitial pneumonia (NSIP) in a patient with cancer-associated myositis (CAM) that emerged along with the recurrence of the cancer. A 60-year-old woman, with a history of partial gastrectomy for gastric cancer 11 years ago, presented with exertional dyspnea with anti-Jo-1 antibody-positive myositis. Surgical lung biopsy showed NSIP with metastatic gastric cancer. Accordingly, her condition was diagnosed as CAM with cancer recurrence. In patients with a history of cancer, development of myositis may indicate cancer recurrence; therefore, careful observation would be necessary. Copyright © 2016 The Japanese Respiratory Society.

Full Text Available Este artigo tem por objetivo estudar de que modo é figurada a morte da personagem Maria Behú, de “Buriti”, Noites do sertão (1956, de João Guimarães Rosa e os símbolos que a ela se agregam. Para tanto, investigamos as focalizações narrativas que incidem sobre Behú, construindo sua imagem como beata, assexuada, atuante na esfera da metafísica, sendo a sua morte o início da intensa vivência da sexualidade pelos demais personagens. “Buriti” narra a estória dos habitantes da fazenda Buriti Bom e daqueles que por lá transitam e as mudanças que ocasionam na vida uns dos outros. Behú é a personagem que mais contrasta com o ambiente, pois dele difere por não apresentar marcas de erotismo ou vida plena. Behú funciona na novela como guardiã da tradição e da cultura, seus usos e seus costumes, estilizados pela linguagem roseana.Palavras-chave: João Guimarães Rosa; Cultura; Linguagem; Morte; Tradição.

The pathogenesis of the idiopathic inflammatory myopathies has been postulated to be an environmental trigger causing the expression of the disease in a genetically predisposed patient. We report a case of anti-Jo1 antibody-positive myositis which was associated with pleural effusions, pericardial effusion with tamponade, and 'mechanic's hands', probably related to the consumption of a fermented Kombucha beverage. Kombucha 'mushroom', a symbiosis of yeast and bacteria, is postulated to be the trigger for our patient's disease owing to the proximity of his symptoms to the consumption of the Kombucha beverage.

Full Text Available O artigo analisa dois romances brasileiros de épocas diferentes - O cortiço, de Aluísio Azevedo, lançado em 1890, e Viva o povo brasileiro, de João Ubaldo Ribeiro, de 1984. Apesar das muitas diferenças que os separam, ambos narram o processo de formação das elites brasileiras, revelando a violência nele envolvida. O naturalismo de Azevedo e o tom paródico de Ribeiro estabelecem, cada um a seu modo, um instigante diálogo com a história brasileira.

Full Text Available Due to their hybrid nature, moving back and forth between life and literature, the letters exchangedby writers constitute valuable documents, not only preserving the biographic memory of their author, but alsoproviding raw material for textual scholars, as already stated by Gérard Genette. The legacy of João Penha(*1839 †1919 may be considered a good example, since the studies on this poet have greatly benefited fromthe use of his correspondence. The letters exchanged by Penha represent not only explicit testimonies of hisideas as a man and as an artist, but are also indirect sources on his work, contextualizing the paths of literarycreation and thus enriching critical edition.

Full Text Available Com o objetivo de comparar a perspectiva estética e a necessidade de tratamento dos ortodontistas e de seus respectivos pacientes, nas cidades de Natal/RN e João Pessoa/PB, distribuíram-se questionários aos pacientes e profissionais locais que, por meio de ilustrações de algumas características das más oclusões, que possibilitaram uma comparação do grau de valorização da estética dentofacial entre ambos os grupos. Por meio de tabelas e testes estatísticos, conclui-se que o padrão braquifacial, o desvio da linha média e o apinhamento ântero-inferior são mais perceptíveis aos profissionais do que aos pacientes e que os profissionais apontaram uma maior necessidade de tratamento da Classe II mandibular e do padrão dolicofacial do que seus respectivos pacientes, na cidade de Natal. Enquanto que em João Pessoa o desvio de linha média é mais perceptível aos profissionais do que aos pacientes; o tratamento da Classe II mandibular, Classe II com AFAI aumentada e sorriso gengival são mais exigidos pelos pacientes do que pelos profissionais e o tratamento do apinhamento ântero-inferior mais solicitado pelos profissionais. Demonstrando que essas diferenças constituem informações valiosas para que cada profissional conheça as expectativas de seus pacientes e, assim, proceda de forma mais esclarecedora durante seus procedimentos clínicos.This work aimed to compare the sense of esthetics, and the capacity to deem the need of orthodontic treatment, between orthodontists and their respective patients in the cities of Natal-RN and João Pessoa-PB, Brazil.

A Close Examination of Jo Boaler's Railside Report

Full Text Available Jo Boaler, an Associate Professor at the Stanford School of Education has just published an already well known study of three high schools that she called Hillside, Greendale, and Railside. This study makes extremely strong claims for discovery style instruction in mathematics, and consequently has the potential to affect instruction and curriculum throughout the country.As is the case with much education research of this nature, Prof. Boaler has refused to divulge the identities of the schools to qualified researchers. Consequently, it would normally be impossible to independently check her work. However, in this case, the names of the schools were determined and a close examination of the actual outcomes in these schools shows that Prof. Boaler’s claims are grossly exaggerated and do not translate into success for her treatment students. We give the details in the following article.Other papers where the researchers have refused to divulge such details as the names of the schools to qualified researchers have affected and continue to affect education policy decisions at the school, state and even national levels. Among these papers are Standards, Assessments – and What Else? The Essential Elements of Standards-Based School Improvement, D. Briars - L. Resnick, CRESST Technical Report 528, (2000 which has been cited repeatedly as justification for the adoption of Everyday Mathematics in school districts throughout the country, and The impact of two standards-based mathematics curricula on student achievement in Massachusetts.

Riordan, J. for Research in Mathematics Education, 32(2001, p. 368-398. which has been used to justify the adoption of the mathematics program “Investigations,” developed by TERC. It is worth noting that currently about 19% of U.S. elementary students use Everyday Mathematics and between 6% and 9% use Investigations, including many of our inner city schools.If we are to reverse the woeful

Full Text Available The movie O romance do vaqueiro voador, by Manfredo Caldas, is built departing from the homonymous cordel by João Bosco Bezerra Bonfim – which, on its turn, was inspired by the documentary Brasília segundo Feldman, by Vladimir Carvalho – aiming to tell, denounce and remember the tragedy the building of the city was. This article aims to discuss some questions: why choose as a character a pot cowboy to wander in the places of the tragedy? Why use a cordel to give origin to another movie?

Silva, Antonia Marly Moura da

2012-01-01

Full Text Available No conto “Desenredo”, integrante de Tutaméia (1967 de João Guimarães Rosa, os arquétipos da dualidade feminina emblematizam os atributos do posicionamento da mulher frente ao mundo. Adúltera, a personagem central é a Bruxa, a Grande prostituta, Lilith, encarnando a alma bacante, o protótipo dionisíaco, porém, no desfecho da narrativa, de forma mágica o amante consegue recompor aos olhos dos outros a imagem da mulher, temida e odiada pelos moradores do lugar. Reintegrando o arquétipo da Grande Mãe, a personagem passa a ser retratada como a Virgem, o arquétipo de Eva, representando a perfeição e a pureza: metas da aspiração masculina reconhecidas pela tradição de Eros. É, pois, seguindo essa linha de reflexão que faremos uma leitura do referido conto procurando reconhecer símbolos e arquétipos da dualidade expressos na arquitetura ficcional

Owing to the amazing bulk of his texts, including more than nine hundred homilies and several letters and theological tracts, as well as his intervention as an active religious leader in Antioch and Constantinople, the two most important Roman eastern cities in antiquity, he became an outstanding personality in the History of the Church. Ordained as presbyter in Antioch in 386, John was allowed by his bishop, Flavian, to preach in the Antiochene churches. Henceforward, he started carrying out an intense missionary activity in order to spread Christian values amidst his congregation.

Effect of the decommissioned Roger open dump, João Pessoa, Brazil, on local groundwater quality

Full Text Available Throughout 45 years (1958-2003 the solid wastes from João Pessoa were disposed off in the former Roger’s open dump, which is situated adjacent to the mangrove at the sides of Sanhauá river, intensifying environmental problems and threatening the health of people living nearby. Between 1999 and 2003 the decommissioned open dump received wastes from the cities of Cabedelo and Bayeux. Several environmental impacts result from this inadequate disposal of solid wastes, including the pollution of groundwater nearby the former Roger´s open dump, which is the major point of investigation of this paper. The water quality of 6 wells situated in the region of influence of the open dump were monitored. Results have shown that the groundwater near the open dump cannot be drunk by the population without previous treatment, since it has some parameters of water quality in discordance with Brazilian legislation concerned with drinking water. Results have also shown that the level of pollution is higher in the wells closer to the open dump.

Rethinking the Notion of National Identity in the Novel The Redbreast by Jo Nesbo

Directory of Open Access Journals (Sweden)

Ivana Bančić

2014-06-01

Full Text Available This paper sets out to examine the extent to which the novel The Redbreast by Jo Nesbo confirms the hypothesis that in the 21st century the crime novel has become a platform suitable for the examination of national identity and the nature of violence in given social surroundings. The paper introduces the hypothesis that there is an undercurrent of unease perceivable in contemporary Norwegian society. The existence of the supporters of the Nazi regime in the history of the nation which after World War II has constituted itself as a modern, tolerant and multicultural society, causes a crisis of identity and evokes a new take-off of right-wing politics. Therefore, the policy of resistance to Nazism and the celebration of tolerance and multiculturalism are on slippery ground. But Nesbo's re-examination of national identity is not conducted solely for the purpose of questioning the absoluteness of ethical positions of good and evil; Nesbo transposes the contemporary Norwegian crime novel from the domain of subjective violence into the realm of objective violence. The paper argues that Nesbo explores the categories of the immoral and the righteous within Norwegian society, pinpointing thereby the dangers of a policy which uses the fear of immigrants as a means of mobilising the nation.

As associações mineralógicas determinadas para os stockscheider quartzo-moscovíticos e pegmatíticos, representadas por columbita-tantalita, cassiterita, gahnita, zircão, xenotímio e monazita, são semelhantes às determinadas para os demais pegmatitos da Província Pegmatítica de São João del Rei.

[Genetic Study of Primary Dystonias: Recommendations from the Centro Hospitalar São João Neurogenetics Group].

Monteiro, Ana; Massano, João; Leão, Miguel; Garrett, Carolina

2017-04-28

The primary dystonias are a particular group of dystonias of presumed genetic origin, with a wide age of onset and variable progression. The diagnosis is, therefore, a challenge and the issue of the genetic investigation presents frequently in clinical practice. In the past few years several gene mutations have been identified as causative of primary dystonias. The choice of molecular testing is complex, given the clinical specificities and low frequency of these entities and the cost of genetic testing. It must follow observation by specialized clinicians highly differentiated in this area and be supported by a rational plan of investigation. The Centro Hospitalar São João Neurogenetics Group, a multidisciplinary team of Neurologists and Geneticists with special interest in neurogenetic disorders, devised consensus recommendations for the investigation of the genetic etiology of the primary dystonias, based on international consensus documents and recent published scientific evidence. This manuscript adopts the new classification system for genetic movement disorders, allowing for its systematic and standardized use in clinical practice.

O objetivo deste trabalho foi analisar o uso do solo nos perímetros de proteção de captação de águas subterrâneas, destinados ao abastecimento público na cidade de João Pessoa (PB. A partir dos perímetros de proteção já delimitados, através de visitas de campo e observação de imagem de satélite, foi realizado o estudo do uso do solo nas suas áreas internas. Foi constatado o exercício de atividades proibidas ou condicionadas nas áreas que deveriam ser protegidas. A pesquisa feita demonstrou a necessidade de disciplinamento das atividades potencialmente poluidoras das águas subterrâneas e vem contribuir como um instrumento de utilidade para a construção de políticas para o disciplinamento das atividades no solo urbano.The aquifers, especially those that occur in urban areas, are very susceptible to contamination or pollution due to the concentration of incompatible activities with the areas that should receive restriction on land use. The objective of this work was to analyze land use in the protected groundwater caption perimeter for the public supply in João Pessoa city (Brazil. From protection perimeters already defined, a study was made of the land use of internal areas through field visits, and observation of satellite image. The exercise of activities prohibited or constrained in the areas that should be protected was noted. The research demonstrated the need to regulate activities that potentially pollute the groundwater and contributes as a useful tool for building policies for the planning of activities on urban land.

Solar photolysis of ozone to singlet D oxygen atoms, O(1D)

Blackburn, T.E.

1984-01-01

Ground level solar photolysis rate coefficients (jO 3 ) were measured for the photolysis of ozone by sunlight, (O 3 + hnu( 2 + O( 1 D)). The O( 1 D) atoms produced react with nitrous oxide (N 2 O) carrier gas to form higher oxides of nitrogen (NOx). Computer model predictions show that these are mainly N 2 O 5 and NO 3 . Seventy five days of data were taken during the summer of 1983, at Ann Arbor, Michigan, and are presented in the appendix. Over 390 clear air jO 3 values are correlated with effective ozone column densities, and 500 nm aerosol optical depths. The solar direct beam component of ozone photolysis was measured for the different aerosol optical depths, over two entire days from sun-up to sun-down. Temperature dependence of jO 3 was measured from 10 0 C to 39 0 C with good agreement to models. Comparison of jO 3 versus global and ultraviolet radiation are made under various ozone column densities and aerosol optical depths. A jO 3 -photometer was built using an interference filter to pass only ozone photolyzing light. Improvements to instrumental parts are shown for balloon and aircraft flyable payloads

We present Goldstone radar imaging of four near-Earth asteroids during Feb-Jun 2017. The signal-to-noise ratios were very strong for each object and we obtained detailed images with range resolutions as fine as 3.75 m/pixel. 2017 BQ6 was discovered on Jan 26 and approached Earth within 6.5 lunar distances on Feb 7. Radar images show that it is a strikingly angular object roughly 200 m in diameter with a rotation period of 3 h. Its multi-faceted shape challenges the expectation that it is a rubble pile. 2017 CS was discovered on Feb 2 and approached within 8 lunar distances on May 29. It appears rounded on large scales but has considerable fine-scale topography evident along its leading edges. The images suggest a diameter of 1 km and a spin period consistent with the 40 h period obtained from photometry by P. Pravec (pers. comm.). The highest resolution images show evidence for meter-size boulders, ridges, and broad concavities. 2007 WV4 was imaged in late May and early June, has a diameter of 900 meters, and appears distinctly angular with at least three large facets > 100 m in extent. Tracking of features in the images gives a rotation period of about 12 hours. 2014 JO25 approached within 4.6 lunar distances on April 19. This was the closest encounter by an asteroid with an absolute magnitude brighter than 18 known in advance until 2027, when 1999 AN10 will approach within one lunar distance. Radar imaging shows that 2014 JO25 is an irregular object, consisting of two components connected by a narrow neck. The asteroid has pole on dimensions of roughly 1 x 0.6 km in the images. Imaging with 3.75 m/pixel resolution places thousands of pixels on the object and reveals ridges, concavities, flat regions up to 200 meters long, and radar-bright spots suggestive of boulders. Tracking of features in the images yields a rotation period of about 4.5 hours that is among the fastest of the 50 known contact binaries in the near-Earth population.

Pregnant women with thromboembolic diseases, previous thrombotic episodes or thrombophilia family history were supervised in a multidisciplinary Obstetrics/ Hematology consultation in Centro Hospitalar São João EPE, Porto, Portugal. For the evaluation and medication of these women, a risk stratification scale was used. The aim of this study was to validate a Risk Stratification Scale and thromboprophylaxis protocol by means of comparing it with a similar scale, developed and published by Sarig. We have compared: The distribution, by risk groups, obtained through the application of the two scales on pregnant women followed at Centro Hospitalar São João, Porto, Portugal, consultation; the sensibility and specificity for each one of the scales (DeLong scale, applied to Receiver Operating Characteristic) curves; the outcomes in pregnancies followed in Hospital São João, Porto, PortugalResults: According to our Hema-Obs risk stratification scale, 29% were allocated to low-risk, 47% to high-risk and 24% to very-high-risk groups. According to Galit Sarig risk stratification scale, 24% were considered low-risk, 53% moderate, 16% high-risk and 7% as very high-risk group. In our study we observed 9% of spontaneous abortions, in comparison with 18% in the Galit Sarig cohort. From the application of Receiver Operating Characteristic curve to both risk stratification scales, the results of the calculated areas were 58,8% to our Hema-Obs risk stratification scale and 38,7% to Galit Sarig risk stratification scale, with a Delong test significancie of p = 0.0006. We concluded that Hema-Obs risk stratification scale is an effective support for clinical monitoring of therapeutic strategies.

Full Text Available A cidade de Cachoeira, localizada no Recôncavo Baiano, exerceu grande influência na história do Brasil, não só em questões políticas e econômicas, mas também com relação a cultura. Tanto que foi tombada pelo Instituto do Patrimônio Histórico e Artístico Nacional - IPHAN pelo seu conjunto arquitetônico e paisagístico, sendo considerada Monumento Nacional. Dentre as diversas manifestações e eventos culturais da cidade, destaca-se a Festa de São João da Feira do Porto de Cachoeira, o primeiro São João planejado da Bahia. O marco dessa festa foi o investimento e o apoio da Empresa de Turismo da Bahia - Bahiatursa (empresa governamental de promoção do turismo, em 1972. Após a saída da Bahiatursa da organização do evento e da entrada do poder municipal no final da década de 1980, a festa sofreu mudanças na sua essência, apresentando nos últimos anos sinais de perda da autenticidade. Por isso, o presente artigo traz reflexões acerca da percepção dos moradores locais diante das transformações ocorridas na festa e em sua expressividade cultural. Para a consignação de tais objetivos utilizou-se o estudo de caso e diferentes técnicas de pesquisas, tendo a análise espacial por meio da geotecnologia como principal vetor de investigação. Os resultados indicaram a necessidade de revisão das diretrizes do município, em especial do projeto de organização do São João, desde sua programação até os produtos vendidos, para continuar representante da cultura de raiz do Recôncavo. Desta forma, este artigo contribui para avançar nos estudos ligados a tradição e cultura da Bahia, buscando entender e melhorar as suas contribuições para o desenvolvimento de todos envolvidos no processo.

The so-called jellyfish galaxies are objects exhibiting disturbed morphology, mostly in the form of tails of gas stripped from the main body of the galaxy. Several works have strongly suggested ram pressure stripping to be the mechanism driving this phenomenon. Here, we focus on one of these objects, drawn from a sample of optically selected jellyfish galaxies, and use it to validate sinopsis, the spectral fitting code that will be used for the analysis of the GASP (GAs Stripping Phenomena in galaxies with MUSE) survey, and study the spatial distribution and physical properties of the gas and stellar populations in this galaxy. We compare the model spectra to those obtained with gandalf, a code with similar features widely used to interpret the kinematics of stars and gas in galaxies from IFU data. We find that sinopsis can reproduce the pixel-by-pixel spectra of this galaxy at least as well as gandalf does, providing reliable estimates of the underlying stellar absorption to properly correct the nebular gas emission. Using these results, we find strong evidences of a double effect of ram pressure exerted by the intracluster medium onto the gas of the galaxy. A moderate burst of star formation, dating between 20 and 500 Myr ago and involving the outer parts of the galaxy more strongly than the inner regions, was likely induced by a first interaction of the galaxy with the intracluster medium. Stripping by ram pressure, plus probable gas depletion due to star formation, contributed to create a truncated ionized gas disk. The presence of an extended stellar tail on only one side of the disk points instead to another kind of process, likely gravitational interaction by a fly-by or a close encounter with another galaxy in the cluster.

Dois autores da Bahia foram significativos das primeiras visões de Natureza e da sociedade das Minas do ouro: André João Antonil e Sebastião da Rocha Pita. Ambos produziram obras sobre a gênese do espaço minerador, buscando, de algum modo, integrá-lo a uma história providencial da colonização portuguesa. Para isso, investiram em temas e imagens que, além de condicionados por evidentes interesses políticos e econômicos dos plantadores do litoral, refletem os vínculos discursivos dos coloniais eruditos.This work deals with the cosmological sense of the Nature, which has been intensively studied at the time of baroc representations (17th and 18th centuries, applied to the Portuguese America new context of gold mines discoveries. Two authors from Bahia were very important to the early views on the Nature and on the society in gold mines: André João Antonil and Sebastião da Rocha Pita. Both have made studies about the genesis of the mining space in such a way to integrate it in an opportune history of the Portuguese colonization. To do this, they dealed mainly with subjects and images which reveal discourse links of colonial wise persons, and also which were influenced by political and economical interests of the coastal farmers.

Full Text Available This text analyses João Mário Grilo’s film: O Processo do Rei (The King’s Trial (1989. Based on the trial of Afonso VI, the director was able to remain faithful to the seventeenth century historical setting, but at the same time give it a contemporary feel, while exploring eternal and recurrent aspects of the story itself. Cinema, in this film, works as a stage where the story reveals the scenography that history books habitually conceal. In order to thoroughly examine the issues raised by this text, the article discusses the relationship between cinema and theatre starting with the concept of mise en scéne. What joins and separates these two artistic forms? How has cinema built its own mise en scéne throughout its history while resorting mostly to editing?En este texto analizaré la película O Processo do Rei (1989, de João Mário Grilo.

We report Goldstone delay-Doppler radar imaging of four NEAs obtained during February-June 2017. The signal-to-noise ratios were very strong for each object and we obtained detailed images with range resolutions as fine as 3.75 m/pixel. Delay-Doppler imaging revealed that 2017 BQ6 is a strikingly angular object roughly ~200 m in diameter with a rotation period of ~3 h. The multi-faceted shape is puzzling assuming a rubble-pile structure of this asteroid. 2017 CS was discovered by Pan-STARRS 1 on February 2 and approached within 8 lunar distances on May 29. 2017 CS appears rounded on large scales but has considerable fine-scale topography evident along its leading edges. The images suggest a diameter of ~1 km and rotation visible in the images is consistent with the 40 h rotation period obtained independently by from photometry by P. Pravec (pers. comm.). The highest resolution images show evidence for meter-size boulders, ridges, and broad concavities. 2007 WV4 was imaged in late May and early June. 2007 WV4 appears distinctly angular, with a diameter in the realm of 900 meters, and with at least three large facets more than 100 m in extent. Tracking of features in the images gives a rotation period of about 12 hours. The echoes show a persistent, small topographic feature that extends out from the surface. The nature of this feature is unknown, but it may be a large boulder similar to Yoshinodai seen on 25143 Itokawa. 2014 JO25 approached within 4.6 lunar distances on April 19. This was the closest encounter by an asteroid with an absolute magnitude brighter than 18 known in advance until 2027, when 1999 AN10 will approach within one lunar distance. Radar imaging shows that 2014 JO25 is an irregular object, which consists of two components connected by a narrow neck. The asteroid has a long axis of about 1 km and a short axis of roughly 600 m. The 3.75 m range resolution imaging placed thousands of pixels on the object and reveals ridges, hills, concavities, flat

Sending carmelites to Portuguese America in 1580: the letter from Friar João Cayado as a guideline for action

2014-01-01

Full Text Available Starting with the narrative of the expeditions to conquer Paraíba River, this article attempts to understand the role assigned to the four carmelite friars who boarded in the fleet of Frutuoso Barbosa in 1580. These religious men carried a letter written by Friar João Cayado, the superior of the Portuguese Carmelite Province, which established the first operational guidelines for the Calced Carmelite missionaries travelling to Portuguese territories, besides delegating the necessary powers to the friars for the consolidation of the Order of Our Lady of Mount Carmel in America. Based on these indications, the friars metamorphosed the way they worked, adapting to the local demands by taking the opportunities that arose. Despite the adjustments, the main goal of the work of these religious men in Brazil, which was to meet the spiritual demands of natives and the ordinary population, did not change. The same guideline that directed the carmelites to America was also responsible for the decay of the Order and its near extinction in Brazil in the 19th century.

Os recursos hídricos superficiais produzidos nessa bacia são essenciais ao desenvolvimento do eixo Goiânia-Anápolis-Brasília e, recentemente, com o aumento da demanda hídrica, tem sido relatados conflitos pelo uso da água. Dessa maneira, tem-se que o desenvolvimento de estudos hidrológicos visando ao melhor entendimento e aproveitamento dos recursos hídricos é estratégico para o desenvolvimento da região. Nesse sentido, objetivou-se com este estudo mapear a precipitação média mensal e anual na bacia hidrográfica do Ribeirão João Leite, com o auxílio de técnicas geoestatísticas. Foram avaliados os modelos de semivariograma esférico, exponencial e gaussiano, ajustados pelo método dos mínimos quadrados ponderados, sendo que o modelo utilizado no mapeamento por krigagem foi o que apresentou o menor erro médio indicado pela validação cruzada. Foi constatado bom desempenho das técnicas geoestatísticas no mapeamento da precipitação média mensal e anual, indicado pelos pequenos erros encontrados, podendo-se destacar o modelo de semivariograma exponencial, que se sobressaiu na maioria dos eventos estudados.The pluvial precipitation is the main hydrology variable input in the hydrological cycle and the knowledge of their spatial and temporal behavior is basic material for hydrological studies, watershed and water resource management, among others.

Through an ongoing MUSE program dedicated to study gas removal processes in galaxies (GAs Stripping Phenomena in galaxies with MUSE, GASP), we have obtained deep and wide integral field spectroscopy of the galaxy JO171. This galaxy resembles the Hoag's galaxy, one of the most spectacular examples of ring galaxies, characterized by a completely detached ring of young stars surrounding a central old spheroid. At odds with the isolated Hoag's galaxy, JO171 is part of a dense environment, the cluster Abell 3667, which is causing gas stripping along tentacles. Moreover, its ring counter-rotates with respect to the central spheroid. The joint analysis of the stellar populations and the gas/stellar kinematics shows that the origin of the ring was not due to an internal mechanism, but was related to a gas accretion event that happened in the distant past, prior to accretion on to Abell 3667, most probably within a filament. More recently, since infall in the cluster, the gas in the ring has been stripped by ram pressure, causing the quenching of star formation in the stripped half of the ring. This is the first observed case of ram-pressure stripping in action in a ring galaxy, and MUSE observations are able to reveal both of the events (accretion and stripping) that caused dramatic transformations in this galaxy.

Full Text Available The limnological characteristics and the phytoplankton community of the pelagic region of the São João River, tributary of the Iguaçu River, Iguaçu National Park were analyzed from August 2008 to July 2009. 221 taxa were identified and the Bacillariophyceae class was the most representative. Bacillariophyceae and Chrysophyceae were the dominant classes in density and Bacillariophyceae in biovolume. According to the DCA carried out for phytoplankton density and biovolume, significant differences were identified between the periods, and between the sites and study periods, respectively. The highest richness of species reached 40 taxa in September 2008 at station 1. The Shannon-Wiener diversity indexes and evenness, calculated from the density of phytoplankton, were temporally heterogeneous and spatially similar. In general, the significant temporal variations in the composition of the phytoplankton community were due to variations in limnological conditions, mainly temperature, transparency and nutrients. Spatially the structure was more similar due to the proximity among the stations. Moreover, the similarity of the distribution of communities in lotic environments were due to the unidirectional flow.As características limnológicas e a comunidade fitoplanctônica na região pelágica do Rio São João, tributário do Rio Iguaçu, Parque Nacional do Iguaçu, foram analisadas de agosto de 2008 a julho de 2009.

Um dos seus eixos acompanha a Luta pelo Trabalho protagonizada pelo Movimento dos Trabalhadores Desempregados (MTD, em João Pessoa. Vivencia-se a contradição imposta na relação "qualificação profissional x mercado de trabalho" – que se organiza como uma das dimensões da divisão social do trabalho própria à contradição capital-trabalho. Dentre as atividades do Núcleo, analisa-se um programa de qualificação para combate ao desemprego criado pela Prefeitura Municipal de João Pessoa no fim de 2010, conquistado pelo MTD e executado pela Secretaria de Desenvolvimento Social: QualificaJP. Com o aporte teórico em referenciais marxistas, que versam sobre formação educacional e desenvolvimento social/econômico, analisa-se a contradição condicionada pela estrutura de mercado, que implicou na aceitação emergencial de uma política perpetuadora da dominação dos trabalhadores por aquela. Por isso, desenvolveu-se, sob a perspectiva extensionista, a crítica à manipulação dos trabalhadores pelas políticas de reserva de mercado e de competitividade através das qualificações, como também, o horizonte de que a tomada de consciência através da luta dos trabalhadores desempregados, envolvidos no caso, seria possibilitada pelo aprofundamento da contradição vivenciada - a força de trabalho e sua qualificação genérica não implicam na absorção pelo mercado de trabalho. Entrar em contato com a demanda dos desempregados a partir da extensão significa transformar o Direito em instrumento a favor da sociedade. Os grupos sociais são atores diretos desse desenvolvimento, mas têm suas práticas condicionadas pelo momento histórico em que vivem. Dessa forma, sem o movimento e atuação deles não há transformações na vida cotidiana, cabendo

In the past few years several gene mutations have been identified as causative of the most frequent neurodegenerative dementias (Alzheimer disease and frontotemporal dementia). These advances, along with the complex phenotype-genotype relationships and the costs associated with genetic testing, have often made it difficult for clinicians to decide with regard to a rational plan for the investigation of the genetic etiology of the degenerative dementias. The Centro Hospitalar São João Neurogenetics Group, a multidisciplinary team of Neurologists and Geneticists with special interest in neurogenetic disorders, devised consensus recommendations for the investigation of the genetic etiology of Alzheimer disease and frontotemporal dementia in clinical practice, based on international consensus documents (currently containing partly outdated information) and published scientific evidence on this topic. Alzheimer disease may be caused by mutations in PSEN1, PSEN2 and APP. APOE genotyping is not recommended for the diagnostic or genetic counseling purposes in Alzheimer disease. Frontotemporal dementia may be caused by mutations in several genes such as c9orf72, PGRN, MAPT, TBK1, VCP, SQSTM1, and UBQLN2. This paper pragmatically approaches the process of genetic diagnosis in Alzheimer disease and frontotemporal dementia, with specific recommendations for both disorders.

Full Text Available Este artigo apresenta o conto “Conversa de Bois” de João Guimaraes Rosa em uma perspectiva fabular. O conceito de fábula abarca um grande espectro de significações, que vai desde: resumo, intriga, conjunto, construção, até o conceito mais formalista, que lhe dá um sentido mais material.  No entanto, imprimiu-se no gênero como característica principal, o cumprimento de uma ação e o uso do antropomorfismo (quando animais assumem características humanas. Na verdade, essa característica é que define o gênero fábula, pois as personagens principais são animais.  O termo fábula vem do latim, fari, que significa falar ou do grego, phao,significando contar algo.  A narrativa tem uma natureza simbólica e/ou alegórica, retratando uma situação vivida por animais, remetendo-se à situação humana, com o objetivo de transmitir certa moralidade.  Lembrando a estrutura proppiana entende-se que ao explorar a fábula, o autor mineiro recusa o estado efêmero do fazer literário, entendendo-o como constante e cíclico, um eterno exercício de reconhecimento. Não há como encerrar algo essencialmente inclinado a se perpetuar.  A obra literária se emancipa de seu tempo, contexto e espaço, seguindo como expressão autônoma que é. A conversa é de bois e os ouvintes são os humanos.  A literatura e o sertão são do mundo.

Objectives Previous work in humans and in animal models supports a key role for histidyl-tRNA synthetase (HRS=Jo-1) in the pathogenesis of idiopathic inflammatory myopathy. While most investigations have focused on the ability of HRS to trigger adaptive immune responses, in vitro studies clearly indicate that HRS possesses intrinsic chemokine-like properties capable of activating the innate immune system. The purpose of this study was therefore to examine the ability of HRS to direct innate immune responses in a murine model of myositis. Methods Following intramuscular immunization with soluble HRS in the absence of exogenous adjuvant, selected strains of mice were evaluated at different time points for histopathologic evidence of myositis. ELISA-based assessment of autoantibody formation and CFSE proliferation studies provided complementary measures of B and T cell responses triggered by HRS immunization. Results Compared to appropriate control proteins, a murine HRS fusion protein induced robust, statistically significant muscle inflammation in multiple congenic strains of C57BL/6 and NOD mice. Time course experiments revealed that this inflammatory response occurred as early as 7 days post immunization and persisted for up to 7 weeks. Parallel immunization strategies in DO11.10/Rag2−/− and C3H/HeJ (TLR4−/−) mice indicated that the ability of murine HRS to drive muscle inflammation was not dependent on B cell receptor or T cell receptor recognition and did not require TLR4 signaling. Conclusion Collectively, these experiments support a model in which HRS can trigger both innate and adaptive immune responses which culminate in severe muscle inflammation that is the hallmark of idiopathic inflammatory myopathy.

Full Text Available The Management Accounting has several tools that can provide administrative support to the entities in the decision-making process. Therefore, this study aimed to make a survey on the use of these tools by the companies providing accounting services responsible for accounting of Small and Medium Enterprises located in the metropolitan area of João Pessoa. The method used was the bibliographical and descriptive. In order to obtain the information needed to perform the study, semi-structured questionnaire was used, with closed and open questions, applied to the leaders of 31 accounting companies from an universe of 135 registered and active in Paraíba Accounting Regional Council in 2013. The knowledge and application of the management tools by the office was verified - the results indicate that accountants know most of the tools, but they do not apply these tools in their clients in the same proportion. This scenario was partially justified when they answered during the survey that the Implantation Phase is considered the most difficult to apply the tools in their clients. Among the management tools, Cash Flow and the Strategic Planning were the most cited about knowledge and applicability, on the other hand, the PROCEM certificate and Downsizing were the least mentioned.

Full Text Available A cidade de João Pessoa, na Paraíba, vem sendo submetida, nos últimos anos, a um forte crescimento urbano. Nesse contexto, este trabalho verificou entre as décadas de 1980 e 2000 variações climáticas significativas que possam ser correlacionadas com o crescimento urbano. Para tanto, utilizaram-se imagens de satélite nos anos de 1977 e 2009 para o cálculo da área edificada, bem como foram utilizadas séries de dados das variáveis climáticas: precipitação pluviométrica e temperatura do ar, colhidas em duas estações instaladas na malha urbana, e uma terceira, tomada como estação de referência, fora da malha urbana. Para a caracterização do crescimento da cidade, utilizaram-se dados quantitativos da população residente constantes dos censos demográficos de 1872 a 2009. Para a verificação do ritmo do comportamento da série temporal de temperatura e precipitação foram gerados gráficos da temperatura média e do acumulado mensal dos meses correspondentes aos trimestres mais quentes e menos quentes do período de 1984 a 2008. Dos resultados obtidos do tratamento e análise dos dados pode-se verificar que a temperatura do ar da cidade aumentou nos últimos 26 anos, havendo-se detectado que as temperaturas do ar sofreram elevações mais expressivas nos meses do trimestre mais quente, fato que pode ser correlacionado com a expansão da malha urbana.

Perbedaan tersebut juga ditemukan dalam transformasi naskah Macbeth karya William Shakespeare ke film Throne of Blood atau Kumonosu-Jo karya Akira Kurosawa yang menjadi objek material penelitian ini. Kreativitas film terhadap karya sastra aslinya disebabkan adanya perbedaan yang mendasar antara karya sastra dan film, yakni medium. Karya sastra dalam hal ini menggunakan medium bahasa, sedangkan film menggunakan medium gambar dan suara. Terdapat suatu peristiwa tertentu yang dapat dimunculkan dengan baik pada karya sastra, tetapi tidak dapat dimunculkan dalam film, atau sebaliknya.

In recent decades, a long and increasing list of monogenic neurodegenerative ataxias has been identified, allowing for better characterization of the pathophysiology, phenotype and prognosis of this heterogeneous group of disorders, while also revealing potential new therapeutic targets. However, the heterogeneity and complexity of the genotype-phenotype relationships and the high costs of molecular genetics often make it difficult for clinicians to decide on a molecular investigation based on an unbiased rational plan. Clinical history is essential to guide the diagnostic workup, but often the phenotype does not hold enough specificity to allow for predicting the genotype. The Group of Neurogenetics of the Centro Hospitalar São João, a multidisciplinary team of neurologists and geneticists with special interest in neurogenetic disorders, devised consensus recommendations for the investigation of the genetic aetiology of neurodegenerative ataxias in clinical practice, based on international consensus documents (currently containing potentially outdated information) and published scientific evidence on this topic. At the time these recommendations were written, there were around 10 well described autosomal recessive loci and more than 27 autosomal dominant loci for neurodegenerative ataxias. This document covers, in a pragmatic way, the rational process used for the genetic diagnosis of neurodegenerative ataxias, with specific recommendations for the various groups of these heterogeneous diseases, per the Portuguese reality.

1993-09-01

The present studies evaluated the ability of jojoba meal (JO) to inhibit feed intake of broiler breeder pullets to limit body weight gain as recommended by the breeder company. A first experiment, using graded levels of JO supplementation (0 to 12%), was conducted to establish appropriate JO supplementation. Adequate reduction of growth rate was obtained with 4% JO supplementation. However, notwithstanding their similar growth rate, 4% JO chickens consumed considerably more feed compared with feed-restricted chickens. The dose-dependent impairment of feed intake with increasing levels of JO supplementation was also associated with increased plasma growth hormone and thyroxine and with decreased plasma insulin-like growth factor-I and triiodothyronine concentrations compared with 0% JO chickens. A second experiment included a pair-fed group. Notwithstanding their similar feed intake, 4% JO chickens gained significantly less body weight compared with their pair-fed counterparts. The 4% JO chickens also had a longer feed transit time per kilogram body weight. Again, circulating levels of the somatotrophic and thyrotrophic hormones were altered according to the dietary treatment. From all these observations, it was concluded that the growth retardation caused by JO supplementation was provoked by an inhibition of appetite linked with the simmondsin content of JO as well as by other antinutritional compounds affecting digestibility.

Full Text Available The main altar of the church of Pavia (Mora, South of Portugal shows a 16th century panel painting depicting The Conversion of Saint Paul attributed to Francisco João, a local painter, born in Évora, active in that region between 1563 and 1595. With the aim of identifying the materials responsible for the colours exhibited by the painting and characterizing its technique, the panel was examined in situ with the naked eye and with the help of a magnifying lens. Nine paint samples were collected for analysis by optical microscopy, scanning electron microscopy - energy dispersive X-ray spectrometry (SEM-EDX, Fourier transformed infrared spectroscopy (FTIR and high-performance thin layer chromatography (HPTLC. On top of a ground layer made of gypsum and animal glue, the painting was done with lead white, lead-tin yellow, ochre, minium, red ochre, vermillion, azurite, verdigris or copper resinate, carbon black and a non identified red lake. In most cases, the samples show a succession of two or three layers of paint over the ground. Generally, this structure results from the modelling work of the painter and not from overlapping motives. In each layer, the colours were usually created by mixtures of a coloured pigment with white. In two cases, the pigments were used pure. Only the red areas show mixtures of a larger number of materials.

A comparative study of gas-gas miscibility processes in underground gas storage reservoirs

Energy Technology Data Exchange (ETDEWEB)

Rafiee, M.M.; Schmitz, S. [DBI - Gastechnologisches Institut gGmbH, Freiberg (Germany)

2013-08-01

Intermixture of gases in underground gas reservoirs have had great weight for natural gas storage in UGS projects with substitution of cushion gas by inert gases or changing the stored gas quality or origin, as for the replacement of town gas by natural gas. It was also investigated during the last years for Enhanced Gas Recovery (EGR) and Carbon Capture and Storage (CCS) projects. The actual importance of its mechanisms is discussed for the H{sub 2} storage in Power to Gas to Power projects (PGP). In these approaches miscibility of the injected gas with the gas in place in the reservoir plays an important role in the displacement process. The conditions and parameters for the gas-gas displacement and mixing have been investigated in previous projects, as e.g. the miscibility of CO{sub 2} with natural gas (CLEAN). Furthermore the miscibility process of town gas with natural gas and sauer gas with sweet gas were also previously measured and compared in laboratory. The objective of this work is to investigate the miscibility of H{sub 2} injection into natural gas reservoirs using a compositional and a black oil reservoir simulator. Three processes of convection, dispersion and diffusion are considered precisely. The effect of gas miscibility is studied for both simulators and the results are compared to find optimum miscibility parameters. The findings of this work could be helpful for further pilot and field case studies to predict and monitor the changes in gas composition and quality. In future this monitoring might become more important when PGP together with H{sub 2}-UGS, as storage technology, will help to successfully implement the change to an energy supply from more renewable sources. Similarly the method confirms the use of the black oil simulator as an alternative for gas-gas displacement and sequestration reservoir simulation in comparison to the compositional simulator.

This paper reports on developing a global gas business, a British Gas plc's strategy for evolving a state owned U.K. gas company to a privatized worldwide oil and gas giant. By 2000, BG's global gas business is expected to provide 20% of its revenues, compared with 40% each from its exploration and production operations and its U.K. gas business. The global gas unit (GGU) plans to meet its targets mainly through acquiring holdings in gas transmission and distribution companies around the world. In the 12 months since GGU was established, it has made two such major acquisitions in this area. BG acquired Consumers Gas Co., Ltd., Ontario, Canada's biggest natural gas distribution company, for $943.5 million. It also took a 10% stake in Catalana de Gas SA, Barcelona, the largest privately owned gas utility in Spain and in terms of number of customers, the fourth largest in western Europe. BG also is targeting additional revenues from developing gas fired cogeneration systems in developing countries with gas reserves but no established transmission and distribution systems

In chemical materials there exist hazardous materials causing health damages, environmental pollution, fires and explosions. The hazard analysis has been noted as a means for preventing accidents due to chemical materials. This means leads to an effective method of recognizing hazard, evaluating the risk, and lowering the degree of hazard to an allowable level. This paper describes a hazard analysis of autoreactive materials, out of chemical materials causing fires and explosions, which may react by theirselves and cause accidents. In particular, an example is introduced in which this hazard analysis method is adapted to an experimental production of the next generation gas generating agent for automobile collision safety air-bags. In this manufacturing process, in kneading and granulating processes where lots of materials are handled, materials are used in a moistened state, thus countermeasures for preventing occurrence of combustion and explosion being taken. 5 refs., 2 figs., 4 tabs.

The technologies and practices that have enabled the recent boom in shale gas production have also brought attention to the environmental impacts of its use. It has been debated whether the fugitive methane emissions during natural gas production and transmission outweigh the lower carbon dioxide emissions during combustion when compared to coal and petroleum. Using the current state of knowledge of methane emissions from shale gas, conventional natural gas, coal, and petroleum, we estimated up-to-date life-cycle greenhouse gas emissions. In addition, we developed distribution functions for key parameters in each pathway to examine uncertainty and identify data gaps such as methane emissions from shale gas well completions and conventional natural gas liquid unloadings that need to be further addressed. Our base case results show that shale gas life-cycle emissions are 6% lower than conventional natural gas, 23% lower than gasoline, and 33% lower than coal. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty whether shale gas emissions are indeed lower than conventional gas. Moreover, this life-cycle analysis, among other work in this area, provides insight on critical stages that the natural gas industry and government agencies can work together on to reduce the greenhouse gas footprint of natural gas.

Origin of natural gas; Tennen gas no kigen

Natural gas, which is a general term of flammable hydrocarbon gases such as methane, is classified by origin into the following categories : (1) oil field gas (oil gas), (2) aquifers (bacteria-fermented methane), (3) coal gas (coal field gas), and (4) abiogenetic gas. The natural gas which has (1-4) origins and is now used as resource in a large quantity is (1) oil field gas. This gas is a hydrocarbon gas recovered in the production process of petroleum and contains components such as ethane, propane and butane. To the contrary, (2) aquifers and (3) coal gas have methane as main component. As (4) abiogenetic methane, there are gas formed in inorganic reaction in activities of submarine volcanos and deep gas (earth origin gas). Oil field gas has kerogen origin. Aquifers were formed by fermentation of organic matters. Coal gas was formed by coalification of vitrinite. As abiogenetic methane, there are inorganic reaction formation gas and deep gas, the latter of which exists little as resource. 7 refs., 11 figs., 1 tab.

The influence of jojoba oil (JO) incorporation in the diet on stomach emptying and intestinal transit time, and the digestion and absorption of JO were investigated in short-term feeding studies in rats. The animals were fed purified diets containing 18% (w/w) fat, of which half consisted of a mixture of lard and sunflower seed oil (SF) supplemented with an equivalent amount of JO. The control animals were fed a mixture of lard and SF (18%). No treatment-related differences were observed in the rate of stomach emptying or the intestinal transit time. Comparative lipid analysis of lymph, intestinal content, intestinal mucosa and faeces indicated that most of the ingested JO was degraded and absorbed. Part of the JO was present as wax ester in the lymph. Hydrolysis of JO was much slower than that of triacylglycerols and continued in the alimentary tract beyond the small intestine due to bacterial processes. JO did not influence the absorption of the conventional fat.

Full Text Available The use of fragrances to attract males of Euglossinae bees has been an important tool to increase the knowledge of the group. In the Northeastern of Brazil, studies on euglossine bees are still uncommon, mainly in urban areas. The goals of this study are to identify the Euglossinae species composition, to know the diversity and the community structure of Euglossinae species, verify their preferences for different fragrances and evaluate the phenology of these species, in two Atlantic Forest fragments of the city of João Pessoa, Paraíba state, Brazil. Bees were sampled at 15 days intervals, over the course of one year, from 8:00 to 17:00 hours, through the use of traps baited with seven types of fragrances. In both areas, 1082 individuals belonging to nine species were sampled. None significant difference of diversity and relative abundance of bees between fragments were observed. Eucalyptol was the most attractive fragrance. Bees were more abundant between 8:00 and 9:00 AM. Visits to the fragrances were more frequent from the middle of dry season to the beginning of the rainy season and positively correlated with the monthly mean temperature. Most species of bees visited all the baits over the year, but the number of attracted males was highest in April.

Gas-on-gas competition in Shanghai

Manuhutu, Chassty; Owen, Anthony D.

2010-01-01

In common with other major economic centres in China, Shanghai's energy consumption has been increasing rapidly to support the high growth rate of its economy. To achieve rational, efficient and clean use of energy, together with improved environmental quality within the city, the Shanghai municipal government has decided to expand the supply and utilization of natural gas. Shanghai plans to increase the share of natural gas in its primary energy mix to 7 per cent by 2010, up from 3 per cent in 2005. This increase in natural gas demand has to be matched with a corresponding increase in supply. To date, the Shanghai region has relied on offshore extracted natural gas but this supply is limited due to the size of the reserves. Since 2005, the West-East pipeline has provided an alternative for Shanghai but demands from other regions could reduce the potential for expanding supplies from that source. Since domestic production will not be sufficient to meet demand in the near future, Shanghai is building a liquefied natural gas (LNG) regasification terminal at the Yangshan deep-water port that would allow an additional supply of more than 3 billion cubic meters per year of natural gas. Malaysia has already committed to supply LNG to the Shanghai terminal at a price that is significantly higher than the wholesale 'city-gate' price for natural gas transported via pipeline, but still lower than the gas price to end-use consumers. The presence of both an LNG terminal and a transmission pipeline that connects Shanghai to domestic gas-producing regions will create gas-on-gas competition. This study assesses the benefits of introducing such competition to one of China's most advanced cities under various scenarios for demand growth. In this paper, the impact of imported LNG on market concentration in Shanghai's gas market will be analysed using the Herfindahl-Hirschmann index (HHI) and the residual supply index (RSI). Our results show that Shanghai remains a supply

Reducing the greenhouse gas footprint of shale gas

International Nuclear Information System (INIS)

Wang Jinsheng; Ryan, David; Anthony, Edward J.

2011-01-01

Shale gas is viewed by many as a global energy game-changer. However, serious concerns exist that shale gas generates more greenhouse gas emissions than does coal. In this work the related published data are reviewed and a reassessment is made. It is shown that the greenhouse gas effect of shale gas is less than that of coal over long term if the higher power generation efficiency of shale gas is taken into account. In short term, the greenhouse gas effect of shale gas can be lowered to the level of that of coal if methane emissions are kept low using existing technologies. Further reducing the greenhouse gas effect of shale gas by storing CO 2 in depleted shale gas reservoirs is also discussed, with the conclusion that more CO 2 than the equivalent CO 2 emitted by the extracted shale gas could be stored in the reservoirs at significantly reduced cost. - Highlights: ► The long-term greenhouse gas footprint of shale gas is smaller than that of coal. ► Carbon capture and storage should be considered for fossil fuels including shale gas. ► Depleted shale gas fields could store more CO 2 than the equivalent emissions. ► Linking shale gas development with CO 2 storage could largely reduce the total cost.

Union Gas and Ontario gas production

Cameron, C.

2001-01-01

A step-by-step review of the tie-in process of new production wells into the Union Gas System is described. Requirements of the producer and those of Union Gas are explained. Also described are the choices available to the producer to sell his gas. He can sell either to Union Gas directly at an agreed upon price, or the producer has the option to have what is called an M13 contract which allows him to sell his gas at Dawn, where it can be stored within parameters of the contract, and sold to any buyer at Dawn at a negotiated rate. This arrangement, while entailing a much greater administrative load than direct sale to Union Gas, nevertheless, allows the producer to take advantage of market fluctuations. A third option provided by Union Gas is to make available to the producer storage space greater than the provisions of the M13 contract at current market rate, thereby opening up the opportunity to the producer to capture additional value in later winter months (when gas is in greater demand)

MÉTODOS: Estudo transversal de 458 famílias, com 558 menores de 5 anos, realizado no município de São João do Tigre. A avaliação da (insegurança alimentar foi realizada mediante aplicação da Escala Brasileira de Insegurança Alimentar (EBIA. A categorização do estado nutricional foi feita a partir dos indicadores estatura/idade, peso/idade e índice de massa corporal (IMC, utilizando-se as curvas da Organização Mundial da Saúde. Também foram analisadas as associações com os indicadores socioeconômicos e biológicos da criança sobre o índice estatura/idade. RESULTADOS: A segurança alimentar foi caracterizada em torno de 13% das famílias, prevalecendo nas demais a condição de insegurança alimentar, sendo a forma moderada a predominante (40,2%. Encontrou-se uma frequência mais baixa do que o normalmente esperado de desnutrição pelo IMC (1,2% e 1,3%, respectivamente, para as áreas rural e urbana, com resultados bem mais elevados ao se considerar o índice estatura/idade (16,8% e 12,9%. A análise de regressão linear multivariada revelou que apenas duas variáveis (renda familiar per capita e escolaridade materna influenciaram significativamente o índice estatura/idade. CONCLUSÃO: Em população de elevado grau de pobreza, baixo Índice de Desenvolvimento Humano e prevalência quase generalizada de insegurança alimentar, o uso exclusivo de indicadores antropométricos pode revelar uma situação aparentemente bem mais favorável. Portanto, os resultados não podem ser interpretados apenas no campo da validade interna, mas no interior de um processo de rápidas mudanças que caracterizam a transição nutricional em curso, atingindo inclusive as populações de condições de vida excepcionalmente desfavoráveis.OBJECTIVE: To analyze the nutritional status of children under five years of age

Gas-ion laser with gas pressure maintenance means

International Nuclear Information System (INIS)

Thatcher, J.B.

1975-01-01

A gas-ion laser is described including means to maintain the ionizable gas in the laser cavity at a rather constant pressure over an extended period of time to significantly increase the useful life of the gas-ion laser. The gas laser includes a gas makeup system having a high pressure source or storage container and a regulating valve. The valve has a permeable solid state orifice member through which the gas flows from the high pressure source to the laser cavity to replenish the gas in the laser cavity and maintain the gas pressure in the cavity rather constant. The permeable orifice member is selected from a solid state material having a permeability that is variable in relation to the magnitude of the energy applied to the orifice member. The gas-ion laser has a valve operating means such as a heater for varying the applied energy such as thermal energy to the member to regulate the gas flow. Additionally, the gas-ion laser has a valve control means that is responsive to the gas pressure in the laser cavity for controlling the valve control means to maintain the pressure at a desired level.

In addition, we have developed distribution functions for key parameters in each pathway to examine uncertainty and identify data gaps - such as methane emissions from shale gas well completions and conventional natural gas liquid unloadings - that need to be addressed further. Our base case results show that shale gas life-cycle emissions are 6% lower than those of conventional natural gas. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty regarding whether shale gas emissions are indeed lower than conventional gas emissions. This life-cycle analysis provides insight into the critical stages in the natural gas industry where emissions occur and where opportunities exist to reduce the greenhouse gas footprint of natural gas.

Natural gas is more than gas power plants

International Nuclear Information System (INIS)

Lind, Oddvar

2000-01-01

Through the Statpipe gas line at Karmoey, Norway supplies 20% of the natural gas on the European market. The pipeline is 'leaking' a little bit of gas to the local communities at Karmoey and Haugesund. These communities have replaced 65% of their oil consumption with natural gas, which is a fine contribution to a better environment. The supplier of the natural gas, Gasnor ASA in this case, claims an energy efficiency of 90% at the end user because the gas burns directly and the loss in the pipeline is minimal. The efficiency of natural gas utilisation is twice that of the planned gas power stations in West-Norway, subtracting the losses in the electrical network. Gasnor ASA competes with oil suppliers and, if necessary, with electric utilities. The county hospital at Haugesund is quoted as an example. The hospital has two large boilers with dual fuel burners. They have been using natural gas since 1998 because it was worth while both economically and environmentally. The use of natural gas in the transport sector would be very important, but the necessary infrastructure is very little developed. For instance, five diesel-powered ferries on the Boknafjord emit as much NOx as the planned gas power plant at Kaarstoe

The aim of this study is to map the technical, economic and organizational options and limitations of feeding biogas back into the natural gas grid by means of regional co-digestion. Emphasis is put on feeding back into the natural gas grid, analogous to a comparable situation in a number of landfill gas projects. This report first provides insight into the energetic potential of co-digestion. Next several landfill gas projects are examined that feed back into the natural gas grid. After that the political and policy-related issues and preconditions for feeding back biogas from co-digestion are discussed, including the technical and economic aspects. Finally, a picture is painted of the future potential of green gas. [mk] [nl

Role of stranded gas in increasing global gas supplies

Attanasi, E.D.; Freeman, P.A.

2013-01-01

This report synthesizes the findings of three regional studies in order to evaluate, at the global scale, the contribution that stranded gas resources can make to global natural gas supplies. Stranded gas, as defined for this study, is natural gas in discovered conventional gas and oil fields that is currently not commercially producible for either physical or economic reasons. The regional studies evaluated the cost of bringing the large volumes of undeveloped gas in stranded gas fields to selected markets. In particular, stranded gas fields of selected Atlantic Basin countries, north Africa, Russia, and central Asia are screened to determine whether the volumes are sufficient to meet Europe’s increasing demand for gas imports. Stranded gas fields in Russia, central Asia, Southeast Asia, and Australia are also screened to estimate development, production, and transport costs and corresponding gas volumes that could be supplied to Asian markets in China, India, Japan, and South Korea. The data and cost analysis presented here suggest that for the European market and the markets examined in Asia, the development of stranded gas provides a way to meet projected gas import demands for the 2020-to-2040 period. Although this is a reconnaissance-type appraisal, it is based on volumes of gas that are associated with individual identified fields. Individual field data were carefully examined. Some fields were not evaluated because current technology was insufficient or it appeared the gas was likely to be held off the export market. Most of the evaluated stranded gas can be produced and delivered to markets at costs comparable to historical prices. Moreover, the associated volumes of gas are sufficient to provide an interim supply while additional technologies are developed to unlock gas diffused in shale and hydrates or while countries transition to making a greater use of renewable energy sources.

The study, 'Assesment of greenhouse gas emission from natural gas' by independent consultants Energetics Pty Ltd, shows that natural gas has significantly fewer greenhouses gas emissions than either black or brown cola for the defined life cycle stages. The life cycle emissions from natural gas use by an Australian Major User are approximately 50% less than the emissions from Victorian brown coal and approximately 38% less than the emissions from Australian average black coal. Australian Best Practice gas fired electricity generation is estimated to emit between 514 and 658 kg CO 2 e/MWh. By comparison, Australian Best Practice coal-fired electricity generation is estimated to emit between 907 and 1,246 kg CO 2 e/MWh for black and brown coal respectively. Greenhouse gas emissions from Australian Best Practice gas-fired electricity generation using combined cycle gas turbines (including full fuel cycle emissions) vary from 41% to 46% of the emissions from brown coal-fired electricity generation and 57% to 64% of emissions from black coal-fired electricity generation. Greenhouse gas emissions from direct gas supply water heating range from 1,470 to 2,042 kilograms per annum. This compares with emissions of 1,922 to 2,499 kg for electric heating from gas-fired electricity generation and 3,975 to 5,393 kg for coal-fired electricity generation. The implications for greenhouse policy nationally are also discussed, emphasising the need to review national energy policy, currently tied to 'fuel neutrality' doctrine

Ethylene gas is a naturally occurring gas that has an influence on the shelf life of fruit during their transportation in cargo ships. An unintentional exposure of ethylene gas during transportation results in a loss of fruit. A gas chromatographic system is presented here for the detection of ethylene gas. The gas chromatographic system was assembled using a preconcentrator, a printed 3D printed gas chromatographic column, a humidity sensor, solenoid valves, and an electrochemical ethylene gas sensor. Ambient air was used as a carrier gas in the gas chromatographic system. The flow rate was fixed to 10 sccm. It was generated through a mini-pump connected in series with a mass flow controller. The metal oxide gas sensor is discussed with its limitation in ambient air. The results show the chromatogram obtained from metal oxide gas sensor has low stability, drifts, and has uncertain peaks, while the chromatogram from the electrochemical sensor is stable and precise. Furthermore, ethylene gas measurements at higher ppb concentration and at lower ppb concentration were demonstrated with the electrochemical ethylene gas sensor. The system separates ethylene gas and humidity. The chromatograms obtained from the system are stable, and the results are 1.2% repeatable in five similar measurements. The statistical calculation of the gas chromatographic system shows that a concentration of 2.3 ppb of ethylene gas can be detected through this system.

The technologies are developed for efficiently, economically improving quality of automobile fuels by, e.g., abatement of environmental pollutants present in the oil products. For improvement of hydrodesulfurization rate of gas oil deep hydrodesulfurization process, the catalyst components high in isomerization ability of the hard-to-desulfurize compounds are investigated, and effectiveness of zeolite is confirmed. For production of low-sulfur gas oil by hydrodesulfurization and hydrocracking of heavy oil, the catalyst with small pores is preferable for desulfurization of gas oil as the co-product of the treatment of heavy oil in the presence of catalyst for heavy oil desulfurization. For hydrocracking, the catalysts are prepared, on a trial basis, for achieving the target gas oil sulfur content of 10ppm or less by optimizing the zeolite and matrix properties. For suitability of gas oil qualities, it is found that the hydrogenation step is the rate-determining step among the reaction routes involved in the hydrogenation of difficult-to-desulfurize compounds. The data of low-sulfur gas oil qualities in Europe are collected. (NEDO)

This presentation deals with some of the challenges and possibilities connected with ''stranded'' gas. These are offshore gas reserves, especially associated gas, that is not connected with the market and that cannot be piped onshore, and where reinjection is not profitable, and where flaring off is not an option. There is increasing interest all over the world to find economical and environmentally friendly solutions to this problem. A good solution will render such fields economically developable and will to a high degree increase the total volume of the world's exploitable gas reserves. Since synthesis gas is a dominating cost element in most chemical conversion processes for gas, the synthesis gases are discussed in some detail. There is also a discussion of the conversion of the gas to Methanol, Synthetic oil (Syncrude and Synfuels) and to DME (Di-methyl-ether). Two methods for gas transport from the field are discussed; LNG on floating production storage and off loading (FPSO), and Gas hydrates. Principles, limitations and conditions for placing those processes on a FPSO. Finally, the presentation discusses the most important economic factors related to the exploitation of offshore gas, and suggests some possibilities for future development.11 figs.

Feasibility of flare gas reformation to practical energy in Farashband gas refinery: no gas flaring.

Science.gov (United States)

Rahimpour, Mohammad Reaza; Jokar, Seyyed Mohammad

2012-03-30

A suggested method for controlling the level of hazardous materials in the atmosphere is prevention of combustion in flare. In this work, three methods are proposed to recover flare gas instead of conventional gas-burning in flare at the Farashband gas refinery. These methods aim to minimize environmental and economical disadvantages of burning flare gas. The proposed methods are: (1) gas to liquid (GTL) production, (2) electricity generation with a gas turbine and, (3) compression and injection into the refinery pipelines. To find the most suitable method, the refinery units that send gas to the flare as well as the required equipment for the three aforementioned methods are simulated. These simulations determine the amount of flare gas, the number of GTL barrels, the power generated by the gas turbine and the required compression horsepower. The results of simulation show that 563 barrels/day of valuable GTL products is produced by the first method. The second method provides 25 MW electricity and the third method provides a compressed natural gas with 129 bar pressure for injection to the refinery pipelines. In addition, the economics of flare gas recovery methods are studied and compared. The results show that for the 4.176MMSCFD of gas flared from the Farashband gas refinery, the electricity production gives the highest rate of return (ROR), the lowest payback period, the highest annual profit and mild capital investment. Therefore, the electricity production is the superior method economically. Copyright © 2012 Elsevier B.V. All rights reserved.

Full Text Available The growth of Vibrio parahaemolyticus (V. parahaemolyticus in oysters during postharvest storage increases the possibility of its infection in humans. In this work, to investigate the growth or survival profiles in different media, pathogenic V. parahaemolyticus in APW, Jinjiang oyster (JO, Crassostrea rivularis slurry, and live JO were studied under different temperatures. All the strain populations were counted through our double-layer agar plate (DLAP method. In APW, the pathogenic V. parahaemolyticus showed continuous growth under 15, 25, and 35°C, while a decline in behavior was displayed under 5°C. The similar survival trend of pathogenic V. parahaemolyticus in JO slurry and live JO was observed under 5, 25, and 35°C, except the delayed growth or decline profile compared to APW. Under 15°C, they displayed decline and growth profile in JO slurry and live JO, respectively. These results indicate the different sensitivity of pathogenic V. parahaemolyticus in these matrices to temperature variation. Furthermore, nonpathogenic V. parahaemolyticus displayed little difference in survival profiles when inoculated in live JO under corresponding temperatures. The results indicate that inhibition or promotion effect could be regulated under different storage temperature for both pathogenic and nonpathogenic strains. Besides, the DLAP method showed the obvious quickness and efficiency during the bacteria count.

In 2004 a study was published on green gas. Green gas is defined as a gaseous energy carrier from renewable biomass with a similar quality as natural gas. As a result of new developments in the field of co-digestion/fermentation the Dutch Ministry of Economic Affairs asked it's agency SenterNovem to update the 2004 study. The aim of the update is (1) to gain insight into operational aspects of green gas projects, e.g. reliability, efficiency and maintenance aspects; (2) stimulate the production of green gas, taking into account the economics of green gas projects, calculation of the financial gap of green gas production, efficient use of biogas (conversion to electricity or directly input into the natural gas distribution systems, and aspects with regard to commercialization and the market; and (3) the potential of green gas. [Dutch] De laatste jaren wordt er gewerkt aan initiatieven om groen gas te produceren. Een recent initiatief is het opwaarderen van biogas tot aardgaskwaliteit door Biogast, wat er toe zal leiden dat al deze zomer Eneco op kleinschalig niveau duurzaam gas levert aan eindverbruikers. Het potentieel aan groen gas dat mogelijk gemaakt zou kunnen worden, is de laatste jaren ook veranderd.

Full Text Available João Ferreyra da Rosa’s “Treatise on Pestilence in Pernambuco”, published in 1694 was the first document on yellow fever, its symptoms and treatment, and it described the phytomedicines used at the time. Rosa described a hundred medicinal plants used to treat the epidemic; most of them came already prepared from Europe, since the majority of Portuguese physicians rejected the indigenous therapeutic knowledge. However, later, due to the lenght and adverse conditions of maritime trevel, leading to losses in the effectiveness of the active ingredients of such phytotherapeutic products, doctors were obliged to employ native medicinal plants in their treatments. The Brazilian medicinal plants used in the treatment of the first epidemic of yellow fever in Brazil (17th century had been brought up to date from the taxonomic point of view, and were comparable with those used in popular medicine today. As part of the phytotherapeutic treatment of yellow fever at the end of the 17th century, Rose made use of the following medicinal plants: copaíba, macela, maracujá-mirim, red aroeira, angélico and almécega.

Fas stimulation recruits neutrophils and activates macrophages that secrete tumor necrosis factor-α (TNF-α), which aggravates Fas-mediated liver injury. To determine whether nonsteroidal anti-inflammatory drugs modify these processes, we challenged 24-hour-fasted mice with the agonistic Jo2 anti-Fas antibody (4 μg/mouse), and treated the animals 1 h later with saline or ibuprofen (250 mg/kg), a dual cyclooxygenase (COX)-1 and COX-2 inhibitor. Ibuprofen attenuated the Jo2-mediated recruitment/activation of myeloperoxidase-secreting neutrophils/macrophages in the liver, and attenuated the surge in serum TNF-α. Ibuprofen also minimized hepatic glutathione depletion, Bid truncation, caspase activation, outer mitochondrial membrane rupture, hepatocyte apoptosis and the increase in serum alanine aminotransferase (ALT) activity 5 h after Jo2 administration, to finally decrease mouse mortality at later times. The concomitant administration of pentoxifylline (decreasing TNF-α secretion) and infliximab (trapping TNF-α) likewise attenuated the Jo2-mediated increase in TNF-α, the decrease in hepatic glutathione, and the increase in serum ALT activity 5 h after Jo2 administration. The concomitant administration of the COX-1 inhibitor, SC-560 (10 mg/kg) and the COX-2 inhibitor, celecoxib (40 mg/kg) 1 h after Jo2 administration, also decreased liver injury 5 h after Jo2 administration. In contrast, SC-560 (10 mg/kg) or celecoxib (40 or 160 mg/kg) given alone had no significant protective effects. In conclusion, secondary TNF-α secretion plays an important role in Jo2-mediated glutathione depletion and liver injury. The combined inhibition of COX-1 and COX-2 by ibuprofen attenuates TNF-α secretion, glutathione depletion, mitochondrial alterations, hepatic apoptosis and mortality in Jo2-treated fasted mice

Improved gas mixtures for gas-filled particle detectors

Science.gov (United States)

Christophorou, L.G.; McCorkle, D.L.; Maxey, D.V.; Carter, J.G.

Improved binary and tertiary gas mixture for gas-filled particle detectors are provided. The components are chosen on the basis of the principle that the first component is one gas or mixture of two gases having a large electron scattering cross section at energies of about 0.5 eV and higher, and the second component is a gas (Ar) having a very small cross section at and below about 0.5 eV; whereby fast electrons in the gaseous mixture are slowed into the energy range of about 0.5 eV where the cross section for the mixture is small and hence the electron mean free path is large. The reduction in both the cross section and the electron energy results in an increase in the drift velocity of the electrons in the gas mixtures over that for the separate components for a range of E/P (pressure-reduced electron field) values. Several gas mixtures are provided that provide faster response in gas-filled detectors for convenient E/P ranges as compared with conventional gas mixtures.

Rio Vista gas leak study: Belleaire Gas Field, California

International Nuclear Information System (INIS)

Wilkey, P.L.

1992-08-01

The Rio Vista gas leak study evaluated methods for remotely sensing gas leaks from buried pipelines and developed methods to elucidate methane transport and microbial oxidation in soils. Remote-sensing methods were evaluated by singing gas leaks along an abandoned Pacific Gas and Electric (PG ampersand E) gas field collection line in northern California and applying surface-based and airborne remote-sensing techniques in the field, including thermal imaging, laser imaging, and multispectral imagery. The remote-sensing techniques exhibited limitations in range and in their ability to correlate with ground truth data. To elucidate methane transport and microbial oxidation in soils, a study of a controlled leak permitted field testing of methods so that such processes could be monitored and evaluated. Monitoring and evaluation techniques included (1) field measurement of soil-gas concentrations, temperatures, and pressures; (2) laboratory measurement of soil physical/chemical properties and activity of methane-oxidizing microorganisms by means of field samples; and (3) development of a preliminary numerical analysis technique for combined soil-gas transport/methane oxidation. Soil-gas concentrations at various depths responded rapidly to the high rate of gas leakage. The number of methane-oxidizing microorganisms in site soils rapidly increased when the gas leak was initiated and decreased after the leak was terminated. The preliminary field, laboratory, and numerical analysis techniques tested for this study of a controlled gas leak could be successfully applied to future studies of gas leaks. Because soil-gas movement is rapid and temporally variable, the use of several complementary techniques that permit generalization of site-specific results is favored

Environmental and economic benefits could accrue from a safe, above-ground, natural-gas storage process allowing electric power plants to utilize natural gas for peak load demands; numerous other applications of a gas storage process exist. A laboratory study conducted in 1999 to determine the feasibility of a gas-hydrates storage process looked promising. The subsequent scale-up of the process was designed to preserve important features of the laboratory apparatus: (1) symmetry of hydrate accumulation, (2) favorable surface area to volume ratio, (3) heat exchanger surfaces serving as hydrate adsorption surfaces, (4) refrigeration system to remove heat liberated from bulk hydrate formation, (5) rapid hydrate formation in a non-stirred system, (6) hydrate self-packing, and (7) heat-exchanger/adsorption plates serving dual purposes to add or extract energy for hydrate formation or decomposition. The hydrate formation/storage/decomposition Proof-of-Concept (POC) pressure vessel and supporting equipment were designed, constructed, and tested. This final report details the design of the scaled POC gas-hydrate storage process, some comments on its fabrication and installation, checkout of the equipment, procedures for conducting the experimental tests, and the test results. The design, construction, and installation of the equipment were on budget target, as was the tests that were subsequently conducted. The budget proposed was met. The primary goal of storing 5000-scf of natural gas in the gas hydrates was exceeded in the final test, as 5289-scf of gas storage was achieved in 54.33 hours. After this 54.33-hour period, as pressure in the formation vessel declined, additional gas went into the hydrates until equilibrium pressure/temperature was reached, so that ultimately more than the 5289-scf storage was achieved. The time required to store the 5000-scf (48.1 hours of operating time) was longer than designed. The lower gas hydrate formation rate is attributed to a

A method of natural gas liquefaction may include cooling a gaseous NG process stream to form a liquid NG process stream. The method may further include directing the first tail gas stream out of a plant at a first pressure and directing a second tail gas stream out of the plant at a second pressure. An additional method of natural gas liquefaction may include separating CO.sub.2 from a liquid NG process stream and processing the CO.sub.2 to provide a CO.sub.2 product stream. Another method of natural gas liquefaction may include combining a marginal gaseous NG process stream with a secondary substantially pure NG stream to provide an improved gaseous NG process stream. Additionally, a NG liquefaction plant may include a first tail gas outlet, and at least a second tail gas outlet, the at least a second tail gas outlet separate from the first tail gas outlet.

The migration of gas from oil and gas formations to the surface is a problem that greatly affects those surface areas where human activity exists. Underground gas storage facilities and oil fields have demonstrated a long history of gas migration problems. Experience has shown that the migration of gas to the surface creates a serious potential risk of explosion, fires, noxious odors and potential emissions of carcinogenic chemicals. These risks must be seriously examined for all oil and gas operations located in urban areas. This paper presents the mechanics of gas migration, paths of migration and a review of a few of the risks that should be considered when operating a gas facility in an urban area. The gas can migrate in a continuous or discontinuous stream through porous, water-filled media to the surface. The primary force in this migration of gas is the difference between specific weights of gas and water

Hot fuel gas dedusting after sorbent-based gas cleaning

Energy Technology Data Exchange (ETDEWEB)

NONE

1999-07-01

Advanced power generation technologies, such as Air Blown Gasification Cycle (ABGC), require gas cleaning at high temperatures in order to meet environmental standards and to achieve high thermal efficiencies. The primary hot gas filtration process, which removes particulates from the cooled raw fuel gas at up to 600{degree}C is the first stage of gas cleaning prior to desulphurization and ammonia removal processes. The dust concentration in the fuel gas downstream of the sorbent processes would be much lower than for the hot gas filtration stage and would have a lower sulphur content and possibly reduced chlorine concentration. The main aim of this project is to define the requirements for a hot gas filter for dedusting fuel gas under these conditions, and to identify a substantially simpler and more cost effective solution using ceramic or metal barrier filters.

Solid gas reaction phase diagram under high gas pressure

Ishizaki, K.

1992-01-01

This paper reports that to evaluate which are the stable phases under high gas pressure conditions, a solid-gas reaction phase diagram under high gas pressure (HIP phase diagram) has been proposed by the author. The variables of the diagram are temperature, reactant gas partial pressure and total gas pressure. Up to the present time the diagrams have been constructed using isobaric conditions. In this work, the stable phases for a real HIP process were evaluated assuming an isochoric condition. To understand the effect of the total gas pressure on stability is of primary importance. Two possibilities were considered and evaluated, those are: the total gas pressure acts as an independent variable, or it only affects the fugacity values. The results of this work indicate that the total gas pressure acts as an independent variable, and in turn also affects the fugacity values

Surface oxygen vacancy and oxygen permeation flux limits of perovskite ion transport membranes

KAUST Repository

Hunt, Anton

2015-09-01

© 2015 Elsevier B.V. The mechanisms and quantitative models for how oxygen is separated from air using ion transport membranes (ITMs) are not well understood, largely due to the experimental complexity for determining surface exchange reactions at extreme temperatures (>800°C). This is especially true when fuels are present at the permeate surface. For both inert and reactive (fuels) operations, solid-state oxygen surface vacancies (δ) are ultimately responsible for driving the oxygen flux, JO2. In the inert case, the value of δ at either surface is a function of the local PO2 and temperature, whilst the magnitude of δ dictates both the JO2 and the inherent stability of the material. In this study values of δ are presented based on experimental measurements under inert (CO2) sweep: using a permeation flux model and local PO2 measurements, collected by means of a local gas-sampling probe in our large-scale reactor, we can determine δ directly. The ITM assessed was La0.9Ca0.1FeO3-δ (LCF); the relative resistances to JO2 were quantified using the pre-defined permeation flux model and local PO2 values. Across a temperature range from 825°C to 1056°C, δ was found to vary from 0.007 to 0.029 (<1%), safely within material stability limits, whilst the permeate surface exchange resistance dominates. An inert JO2 limit was identified owing to a maximum sweep surface δ, δmaxinert. The physical presence of δmaxinert is attributed to a rate limiting step shift from desorption to associative electron transfer steps on the sweep surface as PO2 is reduced. Permeate surface exchange limitations under non-reactive conditions suggest that reactive (fuel) operation is necessary to accelerate surface chemistry for future work, to reduce flux resistance and push δpast δmaxinert in a stable manner.

The share of natural gas in Northeast Asia's energy mix is quite low despite that the region currently dominates the world LNG trade. In the long term, the region's rapid expansion of gas demand in the coming decades looks very likely, but the LNG dominance in the region's gas market will collapse in parallel with the introduction of a long distance pipeline gas. The most likely timing of pipeline gas introduction in Northeast Asian gas market seems to be during the second half of the next decade. (Author)

The objectives of the present study were to compare the survival function of antisynthetase syndrome (ASS) Jo1-positive patients with ASS non-Jo1 patients, all with interstitial lung disease (ILD), and to evaluate other factors such as the extension of pulmonary disease and the time between the onset of symptoms and diagnosis and its association to survival in a cohort of ASS patients. Patients with ASS, all with ILD, were included. At the baseline, pulmonary function tests were realized and a high-resolution chest tomography was obtained; lung inflammation and fibrosis were measured with the Goh score and the Kazerooni index. The following autoantibodies were measured: Jo1, Ej, Oj, PL7, and PL12. Patients had to be positive for one of them in order to be included in the study. The survival function was estimated and compared with the log rank test, and the hazard ratio (HR) was estimated using Cox regression procedure. Forty-three patients were included, of which six patients died (14 %). Patients who died were different in comparison with survivors as regards the frequency of anti-Jo1 positivity: Survivors had anti-Jo1 autoantibodies more frequently (86 %) than patients who died (50 %). The univariate Cox regression analysis identified four variables associated with survival: Jo1 status, arthritis, extent of ground glass, and consolidation (inflammation) in high-resolution computed tomography (HRCT) and baseline forced vital capacity. The serological status of patients (Jo1-positive vs non-Jo1), the extent of lung inflammation in the HRCT scan, a low forced vital capacity, and arthritis are associated with survival in ASS patients.

Full Text Available In this region, especially in Serbia, common belief is that local distributors of gas used by households don’t charge for gas properly. It is suspected that there are two sources for improper ways of gas charging. Local distributors charge for delivered gas only, according to flow rat but not according to gas quality. It is usual that local distributors deliver gas of different quality than one signed in contract. In this work will be considered only one of aspects inefficient charging for delivered gas by local gas distributors, which is connected to variable atmospheric pressure. There is doubt, that local distributors make mistakes during accounting for delivered gas to costumers in regard atmospheric pressure. At the beginning of every investigation, problem has to be located and recognized. Authors are going to collect as much as possible available data, to elaborate and analyze data by scientific methods and to represent conclusions. So, the aim of this work is to diagnose current state and to approve or disapprove above mentioned suspicions. In our region this theme is very interesting, both because of energy efficiency and air pollution control. In this way both consumer and distributor will know, how mush energy they have really spent.

To lower stability requirement of gas production in UCG (underground coal gasification), create better space and opportunities of development for UCG, an emerging sunrise industry, in its initial stage, and reduce the emission of blast furnace gas, converter gas, and coke oven gas, this paper, for the first time, puts forward a new mode of utilization of multiple gas sources mainly including ground gasifier gas, UCG gas, blast furnace gas, converter gas, and coke oven gas and the new mode was demonstrated by field tests. According to the field tests, the existing power generation technology can fully adapt to situation of high hydrogen, low calorific value, and gas output fluctuation in the gas production in UCG in multiple-gas-sources power generation; there are large fluctuations and air can serve as a gasifying agent; the gas production of UCG in the mode of both power and methanol based on multiple gas sources has a strict requirement for stability. It was demonstrated by the field tests that the fluctuations in gas production in UCG can be well monitored through a quality control chart method.

The Gas Research Institute (GRI) is currently involved in the development of concepts aimed at an enhancement of natural gas service to the consumer. In order to maintain the attractiveness of the gas options to industrial consumers and to reinforce the ''value-in-use'' of natural gas to residential as well as commercial customers, it is essential to develop efficient, economical, and safe means of reducing the ''cost-of-service'', including that of natural gas storage in underground formations. Specifically, research and development (R and D) is needed to explore ways to better utilize existing storage fields and also to develop new storage facilities at minimum cost. GRI is currently sponsoring research projects aimed at controlling gas migration in underground gas storage reservoirs, reducing base (or cushion) gas requirements, understanding the gas-gas phase mixing behaviour via laboratory experiments and reservoir models, developing cost-effective gas separation processes using membranes, and optimizing the operation and maintenance (O and M) costs of underground gas storage operations. This paper provides an overview of the GRI's Gas Storage R and D Programme and highlights key results achieved to date for selected research projects. (author). 16 refs, 6 figs, 3 tabs

Centrifugal gas separator

Sakurai, M

1970-03-27

A centrifugal gas separator of a highly endurable construction and with improved gas sealing qualities utilizes a cylincrical elastic bellows or similar system in cooperation with a system of dynamic pressure operable gas seals as means for removing separated gases from the interior of the rotor drum, collecting the separated gases in their respective separated gas chambers defined by the corresponding bellows and their supporting stationary wall members, gas seals and rotor end caps, and means for discharging to the exterior of the surrounding cylindrical wall member the gaseous components from their respective separated gas chambers. In the vicinity of the rotary drum motor is a mixed gas chamber and means for providing the gas mixture along a co-axial passage into the rotary drum chamber. Orifices are bored into the end caps of the rotary drum to direct the separated gases into the aforementioned separated gas chambers which, through the action of the gas seals, freely slide upon the rotating drum to collect and thereafter discharge the thus separated gases. Therefore, according to the present invention, helium gas used to prevent separated gas remixture is unnecessary and, furthermore, the gas seals and elastic bellows means provide an air-tight seal superior to that of the contact sealing system of the former art.

Full text: New improvised hot gas based Auto TLD badge reader has several advantages over the earlier contact heating based manual badge reader. It requires constant supply of N 2 gas for its operation; The gas supplied using replaceable individual gas cylinders may have some safety hazards in their handling. It was therefore considered worthwhile to setup a N 2 gas assembly/ station outside the lab area and to bring regulated gas supply through network of tubes with proper regulation to the individual readers. The paper presents detailed description of the gas station and distribution system. The system is quite useful and offers several practical advantages for readout of TLD badges on the semiautomatic badge readers based on gas heating. Important advantage from dosimetric point of view is avoidance of gas flow rate fluctuations and corresponding variations in TL readouts

Life cycle water consumption for shale gas and conventional natural gas.

Science.gov (United States)

Clark, Corrie E; Horner, Robert M; Harto, Christopher B

2013-10-15

Shale gas production represents a large potential source of natural gas for the nation. The scale and rapid growth in shale gas development underscore the need to better understand its environmental implications, including water consumption. This study estimates the water consumed over the life cycle of conventional and shale gas production, accounting for the different stages of production and for flowback water reuse (in the case of shale gas). This study finds that shale gas consumes more water over its life cycle (13-37 L/GJ) than conventional natural gas consumes (9.3-9.6 L/GJ). However, when used as a transportation fuel, shale gas consumes significantly less water than other transportation fuels. When used for electricity generation, the combustion of shale gas adds incrementally to the overall water consumption compared to conventional natural gas. The impact of fuel production, however, is small relative to that of power plant operations. The type of power plant where the natural gas is utilized is far more important than the source of the natural gas.

Norwegian Natural Gas. Liberalization of the European Gas Market

International Nuclear Information System (INIS)

Austvik, Ole Gunnar

2003-01-01

Leading abstract. This book focuses on issues that are important for Norway as a major gas exporter and to the development of a liberalized European market. Chapter 2 explains main features of the European gas market. Natural gas is sold in regional markets with independent pricing structure and particularities. In Europe, this has led to large investments for the producers and long-term contracts. The strong market growth and EU's actions to liberalize the market may change this. The organization of the Norwegian gas production and sale is discussed, as well as the reorganization taking place in 2001. Pricing mechanisms are discussed in Chapter 3, both in the ''old'' / existing structure and how a liberalization of the market may change price formation. The increased importance of energy taxation in EU countries is covered in Chapter 4. Even though natural gas is the most environmentally friendly of the fossil fuels, the use of natural gas may be taxed far harder in the future. The report discusses price effects of such a development. Chapter 5 discusses whether or not a gas producer, like Norway, necessarily must earn a resource rent. With the use of economic theory for exhaustible resources it is shown how prices to consumers may increase at the same time as prices to producers drop, where the difference is made up by higher gas taxes to the consuming countries. Transportation of natural gas involves considerable scale advantages and there are often scope advantages from production, storage and sale, as well. Chapter 6 discusses how competition and regulation may influence the functioning and social efficiency of the market, and the concentration of market power. When companies become large, they may exploit market power, supported by the authorities of their respective countries. Chapter 7 focuses on regulatory challenges for the EU, and how the transporters may change between conflicting and cooperation with the EU. Chapter 8 focuses on schedules for

This study endeavours to determine whether farmers adjust their consumption of natural gas and liquefied petroleum gas in response to changes in the unit price of energy. A demand model is specified and estimated. The conclusions suggest that the unit price of natural gas (liquefied petroleum gas) is a factor impacting the quantity of natural gas (liquefied petroleum gas) demanded by farmers, but there is no indication that other types of energy are substitutes for natural gas or liquefied petroleum gas. Additionally, the number of acres irrigated is an important factor driving the demand for natural gas and liquefied petroleum gas. Finally, the estimated models of natural gas and liquefied petroleum gas demand were structurally stable over the period 1971-1989. (author)

Full Text Available To lower stability requirement of gas production in UCG (underground coal gasification, create better space and opportunities of development for UCG, an emerging sunrise industry, in its initial stage, and reduce the emission of blast furnace gas, converter gas, and coke oven gas, this paper, for the first time, puts forward a new mode of utilization of multiple gas sources mainly including ground gasifier gas, UCG gas, blast furnace gas, converter gas, and coke oven gas and the new mode was demonstrated by field tests. According to the field tests, the existing power generation technology can fully adapt to situation of high hydrogen, low calorific value, and gas output fluctuation in the gas production in UCG in multiple-gas-sources power generation; there are large fluctuations and air can serve as a gasifying agent; the gas production of UCG in the mode of both power and methanol based on multiple gas sources has a strict requirement for stability. It was demonstrated by the field tests that the fluctuations in gas production in UCG can be well monitored through a quality control chart method.

Future of gas

Two articles and two columns in this section on the future of natural gas. In the first article attention is paid to the possibility that large natural gas producers are setting up a cartel a la OPEC. Most experts argue that the structure of gas markets makes the gas business much less amenable to cartelisation than the oil business. If that is true, why are so many people in the gas industry afraid of a gas cartel? The second article focuses on the future role of North Africa in the supply of natural gas

Centrifugal gas separator

A centrifugal gas separator of a highly endurable construction and with improved gas sealing qualities utilizes a cylincrical elastic bellows or similar system in cooperation with a system of dynamic pressure operable gas seals as means for removing separated gases from the interior of the rotor drum, collecting the separated gases in their respective separated gas chambers defined by the corresponding bellows and their supporting stationary wall members, gas seals and rotor end caps, and means for discharging to the exterior of the surrounding cylindrical wall member the gaseous components from their respective separated gas chambers. In the vicinity of the rotary drum motor is a mixed gas chamber and means for providing the gas mixture along a co-axial passage into the rotary drum chamber. Orifices are bored into the end caps of the rotary drum to direct the separated gases into the aforementioned separated gas chambers which, through the action of the gas seals, freely slide upon the rotating drum to collect and thereafter discharge the thus separated gases. Therefore, according to the present invention, helium gas used to prevent separated gas remixture is unnecessary and, furthermore, the gas seals and elastic bellows means provide an air-tight seal superior to that of the contact sealing system of the former art.

2018-05-01

The study of gas-water mass transfer in porous media is important in many applications, including unconventional resource extraction, carbon storage, deep geological waste storage, and remediation of contaminated groundwater, all of which rely on an understanding of the fate and transport of free and dissolved gas. The novel visual technique developed in this study provided both quantitative and qualitative observations of gas-water mass transfer. Findings included interaction between free gas architecture and dissolved plume migration, plume geometry and longevity. The technique was applied to the injection of CO2 in source patterns expected for stray gas originating from oil and gas operations to measure dissolved phase concentrations of CO2 at high spatial and temporal resolutions. The data set is the first of its kind to provide high resolution quantification of gas-water dissolution, and will facilitate an improved understanding of the fundamental processes of gas movement and fate in these complex systems.

Flue gas emissions from gas-fired cogeneration units <25 MWe

A total of 900 MW e gas driven combined heat and power (CHP) has now been established in Denmark based on gas engines and gas turbine units less than 25 MW e each. Of the 900 MW e approx. 750 MW e are based on gas engines. Biogas is used as fuel for some 32 MW e of these. Emission limits for NO x and CO are 650 mg/nm 3 (ref. 5% O 2 and electrical efficiency 30% LCV). There is at present no limit for unburned hydrocarbons (UHC) for gas engines or gas turbines. The average emission of unburned hydrocarbons for the Danish gas engine driven CHP units is equal to approx. 3,5% of the fuel used. It is the target of this report to provide the basis for evaluating the planned UHC limit and possible adjustments of the present limit for NO x emission. The average NO x emission from gas turbines slightly exceeds the NO x emission from gas engines. This is due to a number of older gas turbines. Modern gas turbines can achieve significantly lower NO x emission compared to engines. The NO x emission from biogas driven engines is significantly higher than that of natural gas driven units. This is mainly due to NO x -unfavourable engine settings and the use of older units, as there are no legislation concerning NO x emission for the majority of these biogas driven units. The emission of CO and UHC is lower from gas turbines than from gas engines. The NO x emission can be reduced by SCR Catalyst systems. In Denmark 3 gas engine installations use this commercially available technology. Oxidation catalyst for UHC reduction at modern gas engine installations has proven relatively unsuccesful in Denmark until now. Only limited reductions are achieved and many catalysts are toxificated in less than 100 hours of operation. However, long-term field testing of promising UHC reducing catalysts is now being made. UHC reduction by incineration is at the prototype stage. No such plant has yet been set up in Denmark. (Abstract Truncated)

The National Gas Hydrate Program Expedition 01 (NGHP-01) targeted gas hydrate accumulations offshore of the Indian Peninsula and along the Andaman convergent margin. The primary objectives of coring were to understand the geologic and geochemical controls on the accumulation of methane hydrate and their linkages to underlying petroleum systems. Four areas were investigated: 1) the Kerala-Konkan Basin in the eastern Arabian Sea, 2) the Mahanadi and 3) Krishna-Godavari Basins in the western Bay of Bengal, and 4) the Andaman forearc Basin in the Andaman Sea.Upward flux of methane at three of the four of the sites cored during NGHP-01 is apparent from the presence of seafloor mounds, seismic evidence for upward gas migration, shallow sub-seafloor geochemical evidence of methane oxidation, and near-seafloor gas composition that resembles gas from depth.The Kerala-Konkan Basin well contained only CO2 with no detectable hydrocarbons suggesting there is no gas hydrate system here. Gas and gas hydrate from the Krishna-Godavari Basin is mainly microbial methane with δ13C values ranging from −58.9 to −78.9‰, with small contributions from microbial ethane (−52.1‰) and CO2. Gas from the Mahanadi Basin was mainly methane with lower concentrations of C2-C5 hydrocarbons (C1/C2 ratios typically >1000) and CO2. Carbon isotopic compositions that ranged from −70.7 to −86.6‰ for methane and −62.9 to −63.7‰ for ethane are consistent with a microbial gas source; however deeper cores contained higher molecular weight hydrocarbon gases suggesting a small contribution from a thermogenic gas source. Gas composition in the Andaman Basin was mainly methane with lower concentrations of ethane to isopentane and CO2, C1/C2 ratios were mainly >1000 although deeper samples were compositions range from −65.2 to −80.7‰ for methane, −53.1 to −55.2‰ for ethane is consistent with mainly microbial gas sources, although one value recorded of −35.4‰ for propane

Asian gas

This paper reports on natural gas which now appears ready to take a leading role on the world energy stage. Demand for natural gas, and specifically LNG, will be strong throughout the world, particularly in Asia. Indonesia and Malaysia will become much more dependent on natural gas in the Asian market. In Thailand, where remarkable economic growth has been fueled by imported oil and domestically produced natural gas, LNG may soon have to be imported from neighboring countries. The author sees Thailand's imports of natural gas increasing from 1.5 to 4.5 million tons annually. Similarly, Korea's imports of LNG will rise from 2 to 8 million tons between 1987 and 2000. In Japan, energy demand is expected to increase at an even faster rate in the 1990s. Given the opposition to nuclear power generation and growing concern about the greenhouse effect, it is likely that LNG will satisfy a major portion of Japan's increasing demand for energy. Japanese gas companies are studying the possibility of establishing a national pipeline network to move gas beyond metropolitan areas

The construction of large water resources infrastructure project often involved a joint-operation (JO) project between two or more construction companies. The form of JO can be grouped into two categories - an integrated type and a non-integrated type. This paper investigates the reason of forming a JO project made by companies. The specific advantages and problems of JO project is also analysed in this paper. In order to achieve the objectives, three water resources infrastructure projects were selected as case studies. Data was gathered by conducting 11 semi-structured interviews to project owners, contractor managers, and project staffs. Data was analysed by means of content analysis. It was found that the most fundamental factor to form a JO is to win a competition or tender. An integrated model is in favour because it can reduce overhead costs and has a simple management system, while a non-integrated model is selected because it can avoid a sleeping partner and make contractor more responsible for their own job.

Alternative ways to transport natural gas; Transporte alternativo de gas natural

The Brazilian energy matrix has been showing a huge increase in the demand of natural gas due mainly to industries and power plants. Today the Brazilian gas market is supplied with gas produced by PETROBRAS and imported from Bolivia. To increase the Brazilian gas supply, on the short and middle term, PETROBRAS will import LNG (liquefied natural gas) and exploit the new offshore fields discovered on the pre-salt area. The only proven technology available today to bring this offshore gas to the market is the pipeline, but its costs for the pre-salt area are high enough to keep the solution economically attractive. So, PETROBRAS are evaluating and developing alternative ways to transport offshore gas, such as LNG, CNG (Compressed Natural Gas), GTS (Gas-to-Solids or Natural Gas Hydrates) and ANG (Adsorbed Natural Gas). Using information available in the literature, this paper analyses the main concepts of CNG and LNG floating unities. This paper also presents the PETROBRAS R and D results on ANG and GTS aiming at offshore application. (author)

This article focuses on the aim of the American Gas Association to increase natural gas demand in the key areas of gas electric generation, natural gas vehicles, gas cooling, and conversion of oil burning facilities, electric water heaters and household appliances such as space heating, stoves, washers and lighting. The need to improve the reliability of natural gas supplies is discussed. It is anticipated that natural gas will not replace coal as the main energy source for power generation, but that it will help utilities to meet environmental regulations. (UK)

BC gas takes new approach to gas supply optimization

Cawdery, J.; Swoveland, C.

1992-01-01

Wide-ranging changes have taken place in the US and Canada since the mid-1980s in the way that local gas distribution utilities and large industrial customers contract for their gas supplies. This paper reports that these changes have been brought about by open-access policies, the intent of which was to allow customers more latitude to make their gas purchase and transportation arrangements and to improve the access of shippers to available gas transmission capacity. The effects of the new open-access regime have been profound on both sides of the border. More than 70% of North American gas supplies are now sold under unbundled arrangements in which gas supply is contracted under separate commodity and transportation agreements. For local distribution utilities, the numbers of potential supply options have become extremely large. Analysis of these options has become increasingly complex with the need to take account of complicated contract provisions, a wider range of storage options and swap arrangements with other utilities, opportunities for some customers to purchase gas directly and uncertainty about future demand, prices and supplier reliability

Recent projection of the market in global scale shows a tendency in natural gas using replacing mostly the fuel oil. Its market share well increase from 21.1% in 1994 to 24.0% in 2010. The annual energetic use will reach 29.23 x 10{sup 9} Gcal in 2010 (8990 million Nm{sup 3} natural gas/day) versus 18.90 x 10{sup 9} Gcal in 1994 (5810 million Nm{sup 3} natural gas/day). For Brazil, its consumption will increase from 8.7 million Nm{sup 3} natural gas/day in 1994 to 35.9 million Nm{sup 3} natural gas/day in 2010. Projects like Brazil-Bolivia natural gas pipeline, will supply 18 million Nm{sup 3} natural gas/day, which expected to start-up before the year 2000. This projects will supply the Brazilian southern regions, that do not consume natural gas at the current moment. Although there are many different kind of natural gas consumption in the industry this paper presents the technical and economical estimate of the injection in the blast furnace operating with coke or charcoal. The process simulation is done assisted by math modeling developed by White Martins/Praxair Inc. (author)

The impact of northern gas on North American gas infrastructure

2004-01-01

The three business units that Enbridge operates are crude oil pipelines; natural gas liquids (NGL) transportation; and gas transmission and distribution. The need for more infrastructure will increase as the demand for natural gas increases. This presentation outlined the issues that surround and sometimes impede infrastructure development. It also emphasized the need for northern gas supply at a time when conventional natural gas supplies are decreasing and demand is growing. Additional LNG supply is required along with new supply from Alaska, Mackenzie Delta and the east coast. The issue of a secure source of supply was discussed along with northern gas expectations. It is expected that Mackenzie Delta gas (1.2 bcf/day) will be available by 2008 to 2010 and Alaska North Slope gas (4 bcf/day) will be available from 2012 to 2014. Gas demand by industrial, residential, commercial and power generation sectors across North America was illustrated. The challenge lies in creating infrastructure to move the supply to where it is most in demand. General infrastructure issues were reviewed, such as prices, regulatory streamlining, lead times, stakeholder issues and supporting infrastructure. 19 figs

Processing of coke oven gas. Primary gas cooling

The primary cooler is an indispensable part of all byproduct processing plants. Its purpose is to cool the raw gas from the coke oven battery and to remove the accompanying water vapor. The greater part of the cooling capacity is utilized for the condensation of water vapor and only a small capacity is needed for the gas cooling. Impurities in the gas, like naphthalene, tar and solid particles, necessitate a special design in view of the inclination to dirt accumulation. Standard types of direct and indirect primary gas coolers are described, with a discussion of their advantages and disadvantages.

2018-07-01

Judgements of learning (JoL) are often used in memory research as a means for assessing an individual's metacognitive beliefs about their learning. JoL have been shown to reliably predict performance as well as learning behaviours and decisions . Participants may, however, modify their behaviour in response to performing JoL. There has, however, been little consensus as to the reliability and direction of the effect. We report on a meta-analyses that assesses the evidence that memory performance is reactive to JoL. The results indicate that overall providing JoL does not have a significant effect on memory performance (g = 0.054, 95% CI -0.027 to 0.135). However, sub-groups analysis showed that this effect depends on the nature of the stimuli to be recalled, with moderate positive reactivity observed for related word pairs (g = 0.323, 95% CI 0.083 to 0.563) and word lists (g = 0.384, 95% CI 0.146 to 0.622) but no reactivity when pairs were unrelated or a mixture of related and unrelated pairs. These results indicate that researchers should be aware that eliciting JoL may well influence participants' underlying encoding processes, especially when using related word pairs or word lists.

2006-07-01

Natural gas is essential to the world economy. Gas now accounts for almost a quarter of OECD primary energy requirements and is expected to become the second most important fuel in the world in the next decade. Industrial and residential consumers increasingly rely on natural gas to keep their houses warm, their lights on and their factories running. Meanwhile the gas industry itself has entered a new phase. Where gas used to be restricted to regional markets, it is now increasingly traded on a global scale. While gas production and transport requires long-term investment, now it is optimised on a short-term basis. Demand continues to grow, but local gas production has become much more expensive. How should we react? How will demand be satisfied? What changes are required to promote flexibility and trade? What are the implications for gas security, investment and interdependence? At stake is an opportunity to diversify supply and demand - but this goal is threatened by barriers to competition and investment. This book is the first of a new IEA publication series. It takes an unprecedented look at developments in natural gas to 2010, analysing not only the three IEA regions (Asia Pacific, North America and Europe) but also broader global trends, such as the interaction of pipeline gas with LNG which binds the regions together. The Review provides invaluable insights for understanding this dynamic market.

Measurement of a precessional rate of a gas, such as an alkali gas, in a magnetic field is made by promoting a non-uniform precession of the gas in which substantially no net magnetic field affects the gas during a majority of the precession cycle. This allows sensitive gases that would be subject to spin-exchange collision de-phasing to be effectively used for extremely sensitive measurements in the presence of an environmental magnetic field such as the Earth's magnetic field.

An overview is presented of the Venezuelan natural gas industry. The structure of PDVSA, the Petroleos de Venezuela Organization, its foreign and domestic affiliates, and its subsidiaries are discussed. Natural gas resources in Venezuela total 290 trillion cubic feet, and Venezuela's share of world, OPEC and latin American production and reserves are 1%, 11% and 26%, respectively for production and 3%, 6% and 49% for reserves. Venezuela's gas pipeline network, plants, production, and marketing are described. Natural gas production and demand forecasts to 2002 are presented. Gas resources are largely located in eastern Venezuela, and large volumes of natural gas non-associated with crude oil will start to become important in the Venezuelan natural gas industry. 19 figs

Reduction of gas flow nonuniformity in gas turbine engines by means of gas-dynamic methods

Matveev, V.; Baturin, O.; Kolmakova, D.; Popov, G.

Gas flow nonuniformity is one of the main sources of rotor blade vibrations in the gas turbine engines. Usually, the flow circumferential nonuniformity occurs near the annular frames, located in the flow channel of the engine. This leads to the increased dynamic stresses in blades and as a consequence to the blade damage. The goal of the research was to find an acceptable method of reducing the level of gas flow nonuniformity as the source of dynamic stresses in the rotor blades. Two different methods were investigated during this research. Thus, this study gives the ideas about methods of improving the flow structure in gas turbine engine. On the basis of existing conditions (under development or existing engine) it allows the selection of the most suitable method for reducing gas flow nonuniformity.

In recent years, natural gas has gained new momentum because of changes in marketing and regulations. The gas industry has always received an inordinate amount of regulatory control starting at the well head where the gas is produced to the consuming burner tip. Regulations have drastically impacted the availability of gas. Changes in the marketing and regulations have made the natural gas market sensitive at the point of production, the well head. Now, with plentiful supply and ease of transportation to bring the gas from the producing fields to the consumer, natural gas markets are taking advantage of the changed conditions. At the same time, new markets are developing to take advantage of the changes. This section shows consumers, especially the energy planners for large buyers of fuel, the advantages, sources and new methods of securing natural gas supplies. Background on how natural gas is produced and marketed are given. This section lists marketing sources, regulatory agencies and information groups available to help buyers and consumers of this important fuel for US industries and residences. 7 figs., 8 tabs

2012-01-01

Estimates of greenhouse gas (GHG) emissions from shale gas production and use are controversial. Here we assess the level of GHG emissions from shale gas well hydraulic fracturing operations in the United States during 2010. Data from each of the approximately 4000 horizontal shale gas wells brought online that year are used to show that about 900 Gg CH[subscript 4] of potential fugitive emissions were generated by these operations, or 228 Mg CH[subscript 4] per well—a figure inappropriately ...

Russian natural gas policy and its possible effects on European gas markets

International Nuclear Information System (INIS)

Quast, O.; Locatelli, C.

1997-01-01

There is a growing perception among Western European gas experts that Russia has developed a considerable gas surplus - the Russian gas bubble. Thus, the question clearly arises how much gas is available for export and how much gas, over the next 15 to 20 years, can the Russian quasi-monopolist Gazprom market in Western Europe. We consider that Gazprom's export strategy mirrors the approach of Russia's natural gas policy towards the Western European market. In this paper, we will focus on the characteristics of Gazprom's export strategy, its underlying logic, and its impact on Western European gas markets. As a consequence of Gazprom's export strategy, the Russian gas company faces today a price quantity dilemma. Gazprom's problem is to place as much gas as possible in the growing Western European gas market, without destroying downstream gas prices. We argue that Gazprom has adopted a market share expansion and downstream vertical integration strategy, aimed at capturing a part of the downstream gas rent. Although this strategy appears to have initiated a form of gas to gas competition in a number of European consumer markets, this strategy is not based on an aggressive price policy. However, in order to live up to its ambitions, there is a chance that Gazprom will have to somewhat relax traditional contract clauses, such as contract length, indexation terms and take or pay conditions.

Modern gas centrifuge and rarefied-gas dynamics

Lowry, R.A.; Halle, E.V.; Wood, H.G. III.

Today, the modern gas centrifuge appears to be the preferred method for the enrichment of the isotopes of uranium on a commercial scale. That this is the case is the result of diligent development programs pursued in this country as well as in the UK, Germany, and the Netherlands over the several decades since the end of WW II. The theoretical modelling of gas centrifuge performance has made notable advances. However, the theoretical work has been based primarily on continuum fluid dynamics considerations. Centrifuge problems involving rarefied gas dynamics considerations are discussed in this paper

Greenhouse gas emissions from high demand, natural gas-intensive energy scenarios

International Nuclear Information System (INIS)

Victor, D.G.

1990-01-01

Since coal and oil emit 70% and 30% more CO 2 per unit of energy than natural gas (methane), fuel switching to natural gas is an obvious pathway to lower CO 2 emissions and reduced theorized greenhouse warming. However, methane is, itself, a strong greenhouse gas so the CO 2 advantages of natural gas may be offset by leaks in the natural gas recovery and supply system. Simple models of atmospheric CO 2 and methane are used to test this hypothesis for several natural gas-intensive energy scenarios, including the work of Ausubel et al (1988). It is found that the methane leaks are significant and may increase the total 'greenhouse effect' from natural gas-intensive energy scenarios by 10%. Furthermore, because methane is short-lived in the atmosphere, leaking methane from natural gas-intensive, high energy growth scenarios effectively recharges the concentration of atmospheric methane continuously. For such scenarios, the problem of methane leaks is even more serious. A second objective is to explore some high demand scenarios that describe the role of methane leaks in the greenhouse tradeoff between gas and coal as energy sources. It is found that the uncertainty in the methane leaks from the natural gas system are large enough to consume the CO 2 advantages from using natural gas instead of coal for 20% of the market share.

We argue on the basis of the results of 2D analysis of the gas flow in gas centrifuges that a reliable calculation of the circulation of the gas and gas content in the gas centrifuge is possible only in frameworks of 3D numerical simulation of gas dynamics in the gas centrifuge (hereafter GC). The group from National research nuclear university, MEPhI, has created a computer code for 3D simulation of the gas flow in GC. The results of the computer simulations of the gas flows in GC are presented. A model Iguassu centrifuge is explored for the simulations. A nonaxisymmetric gas flow is produced due to interaction of the hypersonic rotating flow with the scoops for extraction of the product and waste flows from the GC. The scoops produce shock waves penetrating into a working camera of the GC and form spiral waves there.

This paper introduces the summary of the partial amendment in the gas business law (which was enforced in March 1995 upon propositions from the General Energy Investigation Council). The amendment consists mainly of deregulation on business rules for gas supply to large users. The amendment may be summarized as follows: the present billing regulations are deregulated for cases that gas purchasers are large users, permitting in principle the pricing to be agreed upon negotiations between the concerned parties; general gas business operators are allowed to supply gas under certain conditions even outside their supply areas, provided the supply is limited to large users; even any other persons than the general gas business operators can supply gas under certain conditions; persons to start newly a large -scale gas supply business shall be applied with the mandatory portions of the safety regulations that have already been imposed on the general gas business operators; clerical works for the national examination on chief gas engineers will be commissioned to civil organizations; and duplicated application of regulations in the gas utility industry law is eliminated for those operators who are subjected to regulations in the electric utility industry law. 1 fig.

Full Text Available A educação é considerada uma importante fonte de transformação do ser social. Provocações e novos desafios surgem a cada dia em busca de analisarmos se estamos atuando ou não de forma moral e ética. A sustentabilidade e o consumismo são características bem opostas, de um lado empresas que primam pelo progresso, oferecem vagas de empregos e beneficiam seres humanos com suas atividades, do outro, uma nova educação, dotada de preocupações com a preservação ambiental. Considerado um dos assuntos mais comentados na atualidade, a educação para sustentabilidade está intrinsecamente ligada à solidariedade, respeito e afetividade e precisa estar conectada a três pilares: prosperidade econômica, respeito ao meio ambiente e proteção social. Para isto, é necessário que as pessoas substituam o pensamento capitalista consumista, mantendo a sustentabilidade. Esta pesquisa teve o objetivo de identificar acontecimentos atuais provocados por uma mineradora no município de São João da Boa Vista e o quanto a conscientização pela Educação para a Sustentabilidade pode proporcionar para a localidade e humanidade. Investigouse a Lei Orgânica e Legislação Municipal a fim de evitarem a ação da mineradora e manter, sem maiores danos, o turismo local e regional.   Education is considered an important source of transformation of social being.

2013-01-01

The objective of this Ph.D. thesis is the development and validation of a VTOL-based (Vertical Take Off and Landing) micro-drone for the measurement of gas concentrations, to locate gas emission sources, and to build gas distribution maps. Gas distribution mapping and localization of a static gas source are complex tasks due to the turbulent nature of gas transport under natural conditions and becomes even more challenging when airborne. This is especially so, when using a VTOL-based micro-drone that induces disturbances through its rotors, which heavily affects gas distribution. Besides the adaptation of a micro-drone for gas concentration measurements, a novel method for the determination of the wind vector in real-time is presented. The on-board sensors for the flight control of the micro-drone provide a basis for the wind vector calculation. Furthermore, robot operating software for controlling the micro-drone autonomously is developed and used to validate the algorithms developed within this Ph.D. thesis in simulations and real-world experiments. Three biologically inspired algorithms for locating gas sources are adapted and developed for use with the micro-drone: the surge-cast algorithm (a variant of the silkworm moth algorithm), the zigzag / dung beetle algorithm, and a newly developed algorithm called ''pseudo gradient algorithm''. The latter extracts from two spatially separated measuring positions the information necessary (concentration gradient and mean wind direction) to follow a gas plume to its emission source. The performance of the algorithms is evaluated in simulations and real-world experiments. The distance overhead and the gas source localization success rate are used as main performance criteria for comparing the algorithms. Next, a new method for gas source localization (GSL) based on a particle filter (PF) is presented. Each particle represents a weighted hypothesis of the gas source position. As a first step, the PF-based GSL algorithm

When stopping the operation of a fuel cell, the gas in the reaction gas system is purged using such an inert gas as nitrogen for inactivation. A gas source such as inert gas bomb must be prepared beforehand for the purpose. This invention relates to a method of production of inert gas from the air collected from atmosphere to use it as the purge gas. The air collected from the atmosphere is passed through an oxygen remover filled with oxidation catalyst to remove oxygen, and dehumidified by a dehumidifier filled with drying agent, the obtained inert drying gas with nitrogen as the main constituent being used as the purge gas. Copper system catalyst supported by silica is used as the oxidation catalyst, and silica gel as the drying agent. After the operation of the fuel cell is re-started, a part of the high temperature fuel gas extracted from the reaction gas system is introduced to the oxygen remover for the reduction of oxidation catalyst and for heat regeneration of dehumidifying agent by the contained hydrogen. 1 fig.

The overall aim of the project was to gain more knowledge about the kinetics of gas hydrate formation especially the early growth phase. Knowledge of kinetics of gas hydrate formation is important and measurements of gas hydrate particle size and concentration can contribute to improve this knowledge. An experimental setup for carrying out experimental studies of the nucleation and growth of gas hydrates has been constructed and tested. Multi wavelength extinction (MWE) was the experimental technique selected for obtaining particle diameter and concentration. The principle behind MWE is described as well as turbidity spectrum analysis that in an initial stage of the project was considered as an alternative experimental technique. Details of the experimental setup and its operation are outlined. The measuring cell consists of a 1 litre horizontal tube sustaining pressures up to 200 bar. Laser light for particle size determination can be applied through sapphire windows. A description of the various auxiliary equipment and of another gas hydrate cell used in the study are given. A computer program for simulation and analysis of gas hydrate experiments is based on the gas hydrate kinetics model proposed by Skovborg and Rasmussen (1993). Initial measurements showed that knowledge of the refractive index of gas hydrates was important in order to use MWE. An experimental determination of the refractive index of methane and natural gas hydrate is described. The test experiments performed with MWE on collectives of gas hydrate particles and experiments with ethane, methane and natural gas hydrate are discussed. Gas hydrate particles initially seem to grow mainly in size and at latter stages in number. (EG) EFP-94; 41 refs.

The paper studied the solar energy use methanol synthesis using CO2 as raw material in the natural gas field with which a large quantity of CO2 is associated. This is a report on the FY 1999 survey. It was found that comparatively many natural gas fields containing CO2 exist also in Asia/Oceania regions. It was also found that when considering the climate and the transportation to Japan, Australia has more advantages in terms of the effective desert area, etc. and is the best site for solar system construction. Various solar concentrating/collecting methods now under development are roughly viewed to extract characteristics and developmental conditions. As to the reforming reaction furnace, it is necessary not only to absorb the world technology, but to develop Japan's original one. The conceptual design and assessment of the system were conducted. About the associated CO2, a limit of the concentration for use was estimated at 25%. In the study of elements of system structure, examined was the thermally combined simulation of heat flow and chemical reaction in the solar heat reaction furnace, and simple models were calculated and subjects were extracted. In a comparison with the conventional methanol synthesis method, this system was found to be excellent in conservation of fossil fuel resources and reduction in CO2 emissions. (NEDO)

Analysis of a multicomponent gas absorption system with carrier gas coabsorption

International Nuclear Information System (INIS)

Merriman, J.R.

1975-03-01

Conventional integrated versions of the packed gas absorber design equations do not account for significant coabsorption of the carrier gas along with the dilute transferring species. These equations, as a result, also neglect the relationship between dilute component transfer and carrier gas coabsorption. In the absorption of Kr and Xe from various carrier gases, using CCl 2 F 2 as the process solvent, carrier coabsorption is substantial. Consequently, a design package was developed to deal with multicomponent gas absorption in systems characterized by carrier gas coabsorption. Developed within the general film theory framework, the basic feature of this design approach is a view of dilute component mass-transfer as a conventional diffusive transfer superimposed on a net flux caused by carrier absorption. Other supporting elements of the design package include predictive techniques for various fluid properties, estimating procedures for carrier gas equilibrium constants, and correlations for carrier gas and dilute gas mass-transfer coefficients. When applied to systems using CCl 2 F 2 as the solvent; He, N 2 , air, or Ar as the carrier gas; and Kr or Xe as the dilute gas; the design approach gave good results, even when extended to conditions well beyond those of its development.

Survey of stranded gas and delivered costs to Europe of selected gas resources

Science.gov (United States)

Attanasi, E.D.; Freeman, P.A.

2011-01-01

Two important trends affecting the expected growth of global gas markets are (1) the shift by many industrialized countries from coal-fired electricity generation to the use of natural gas to generate electricity and (2) the industrialization of the heavily populated Asian countries of India and China. This paper surveys discovered gas in stranded conventional gas accumulations and presents estimates of the cost of developing and producing stranded gas in selected countries. Stranded gas is natural gas in discovered or identified fields that is not currently commercially producible for either physical or economic reasons. Published reserves of gas at the global level do not distinguish between volumes of gas in producing fields and volumes in nonproducing fields. Data on stranded gas reported here-that is the volumes, geographical distribution, and size distributions of stranded gas fields at the country and regional level-are based on the examination of individual-field data and represent a significant improvement in information available to industry and government decision makers. Globally, stranded gas is pervasive, but large volumes in large accumulations are concentrated in only a few areas. The cost component of the paper focuses on stranded conventional gas accumulations in Africa and South America that have the potential to augment supplies to Europe. The methods described for the computation of extraction and transport costs are innovative in that they use information on the sizes and geographical distribution of the identified stranded gas fields. The costs are based on industry data specific to the country and geologic basin where the stranded gas is located. Gas supplies to Europe can be increased significantly at competitive costs by the development of stranded gas. Net extraction costs of producing the identified gas depend critically on the natural-gas-liquids (NGLs) content, the prevailing prices of liquids, the size of the gas accumulation, and the

George, C.M.

1957-12-31

A liquid piston gas pump is described, capable of pumping minute amounts of gas in accurately measurable quantities. The pump consists of a flanged cylindrical regulating chamber and a mercury filled bellows. Sealed to the ABSTRACTS regulating chamber is a value and having a gas inlet and outlet, the inlet being connected by a helical channel to the bellows. A gravity check valve is in the gas outlet, so the gas passes through the inlet and the helical channel to the bellows where the pumping action as well as the metering is accomplished by the actuation of the mercury filled bellows. The gas then flows through the check valve and outlet to any associated apparatus.

Hartnell, Gaynor

2000-01-01

Following the UK Government's initiative for stimulating renewable energy through the Non-Fossil Fuel Obligation (NFFO), the UK landfill gas industry has more than trebled in size in just 4 years. As a result, UK companies are now in a strong position to offer their skills and services overseas. Ireland, Greece and Spain also resort heavily to disposal to landfill. Particularly rapid growth of the landfill gas market is expected in the OECD-Pacific and NAFTA areas. The article explains that landfill gas is a methane-rich mixture produced by anaerobic decomposition of organic wastes in landfills: under optimum conditions, up to 500 cubic meters of gas can be obtained from 1 tonne of biodegradable waste. Data on the number and capacity of sites in the UK are given. The Landfill Gas Association runs courses to counteract the skills shortage in the UK, and tailored courses for overseas visitors are planned

Radon gas in oil and natural gas production facilities

International Nuclear Information System (INIS)

Chandler, W.P.

1994-01-01

Radon gas is a naturally occurring radionuclide that can be found in some oil and natural gas production facilities, either as a contaminant in a natural gas stream or derived from Radium dissolved in formation waters. The gas itself is not normally a health hazard, but it's decay products, which can be concentrated by plate-out or deposition as a scale in process equipment, can be a health hazard for maintenance personnel. To evaluate possible health hazards, it is necessary to monitor for naturally occurring radioactive materials (NORM) in the gas stream and in the formation water. If Radon and/or Radium is found, a monitoring programme should be initiated to comply with National or State requirements. In some instances, it has been found necessary to dispose of silt and scale materials as low level radioactive waste. 8 refs

Vibration-processing interneurons in the honeybee brain

Directory of Open Access Journals (Sweden)

2010-01-01

Full Text Available The afferents of the Johnston’s organ (JO in the honeybee brain send their axons to three distinct areas, the dorsal lobe, the dorsal subesophageal ganglion (DL-dSEG, and the posterior protocerebral lobe (PPL, suggesting that vibratory signals detected by the JO are processed differentially in these primary sensory centers. The morphological and physiological characteristics of interneurons arborizing in these areas were studied by intracellular recording and staining. DL-Int-1 and DL-Int-2 have dense arborizations in the DL-dSEG and respond to vibratory stimulation applied to the JO in either tonic excitatory, on-off-phasic excitatory, or tonic inhibitory patterns. PPL-D-1 has dense arborizations in the PPL, sends axons into the ventral nerve cord (VNC, and responds to vibratory stimulation and olfactory stimulation simultaneously applied to the antennae in long-lasting excitatory pattern. These results show that there are at least two parallel pathways for vibration processing through the DL-dSEG and the PPL. In this study, Honeybee Standard Brain was used as the common reference, and the morphology of two types of interneurons (DL-Int-1 and DL-Int-2 and JO afferents was merged into the standard brain based on the boundary of several neuropiles, greatly supporting the understanding of the spatial relationship between these identified neurons and JO afferents. The visualization of the region where the JO afferents are closely appositioned to these DL interneurons demonstrated the difference in putative synaptic regions between the JO afferents and these DL interneurons (DL-Int-1 and DL-Int-2 in the DL. The neural circuits related to the vibration-processing interneurons are discussed.

Due to the growing number of green gas facilities in the Netherlands more practical knowledge is collected about the production and injection of green gas. Also there was the need to gather data about more practical experiences and knowledge about the gas quality, the performance of gas cleaning and gas treatment systems, as well the integration of green gas in the gas infrastructure. In addition to this, there is a need to get insight in the safety aspects of green gas injection. In order to comply this demand, DNV KEMA en Kiwa Technology measured the quality parameters continuously between June 2012 en January 2013 (three weeks) and discontinuously (gas samples) of green gas at eight production facilities. The measurements have been performed at designated places and are independent from the measurements of the biomethane producer. In order to be sure that the results of DNV KEMA and Kiwa are comparable, a combined measurement program was executed. It results in uniformity for all the measured values: the differences are within the uncertainty level for each component. During the measurement period of three weeks, the gas quality parameters were compared to specifications, written down in the national regulations for the transport and the distribution grid respectively [Dutch] Door het groeiend aantal groengasinvoedingen in Nederland wordt steeds meer praktijkkennis verzameld.

A Tissue-Equivalent Proportional Counter (TEPC), based on a single GEM foil of standard geometry, has been tested with pure propane gas at low pressure, in order to simulate a tissue site of about 1 µm equivalent size. In this work, the performance of GEM with propane gas at a pressure of 21 and 28 kPa will be presented. The effective gas gain was measured in various conditions using a {sup 244}Cm alpha source. The dependence of effective gain on the electric field strength along the GEM channel and in the drift and induction region was investigated. A maximum effective gain of about 5×10{sup 3} has been reached. Results obtained in pure propane gas are compared with gas gain measurements in gas mixtures commonly employed in microdosimetry, that is propane and methane based Tissue-Equivalent gas mixtures.

Laser Gas-Analyser for Monitoring a Source of Gas Pollution

2015-01-01

Full Text Available Currently, the problem of growing air pollution of the Earth is of relevance. Many countries have taken measures to protect the environment in order to limit the negative anthropogenic impacts.In such a situation an objective information on the actual content of pollutants in the atmosphere is of importance. For operational inspection of the pollutant concentrations and for monitoring pollution sources, it is necessary to create high-speed high-sensitivity gas analysers.Laser meters are the most effective to provide operational remote and local inspection of gas pollution of the Earth atmosphere.Laser meter for routine gas analysis should conduct operational analysis of the gas mixture (air. For this a development of appropriate information support is required.Such information support should include a database with absorption coefficients of pollutants (specific to potential sources of pollution at possible measuring wavelengths (holding data for a particular emitter of the laser meter and an efficient algorithms to search the measuring wavelengths and conduct a quantitative analysis of gas mixtures.Currently, the issues, important for practice and related to the development of information support for the laser gas analyzer to conduct important for practice routine measurements remain unclear.In this paper we develop an algorithm to provide an operational search of the measuring wavelengths of laser gas analyser and an algorithm to recover quantitively the gaseous component concentrations of controlled gas mixture from the laser multi-spectral measurements that take into account a priori information about the source-controlled gas pollution and do not require a large amount of computation. The method of mathematical simulation shows the effectiveness of the algorithms described both for seach of measuring wavelengths and for quantitative analysis of gas releases.

Gas composition and isotopic geochemistry of cuttings, core, and gas hydrate from the JAPEX/JNOC/GSC Mallik 2L-38 gas hydrate research well

Science.gov (United States)

Lorenson, T.D.

1999-01-01

Molecular and isotopic composition of gases from the JAPEX/JNOC/GSC Mallik 2L-38 gas hydrate research well demonstrate that the in situ gases can be divided into three zones composed of mixtures of microbial and thermogenic gases. Sediments penetrated by the well are thermally immature; thus the sediments are probably not a source of thermogenic gas. Thermogenic gas likely migrated from depths below 5000 m. Higher concentrations of gas within and beneath the gas hydrate zone suggest that gas hydrate is a partial barrier to gas migration. Gas hydrate accumulations occur wholly within zone 3, below the base of permafrost. The gas in gas hydrate resembles, in part, the thermogenic gas in surrounding sediments and gas desorbed from lignite. Gas hydrate composition implies that the primary gas hydrate form is Structure I. However, Structure II stabilizing gases are more concentrated and isotopically partitioned in gas hydrate relative to the sediment hosting the gas hydrate, implying that Structure II gas hydrate may be present in small quantities.

Supercompressibility factor program. A new calculation method for real gas factors developed by the American Gas Association/Gas Research Institute

Energy Technology Data Exchange (ETDEWEB)

Luebbe, D.

1987-07-01

The innovative US calculation method for natural gas real gas factors is applicable to great pressure and temperature ranges and does not involve any restrictions as to the quality of natural gas. The results obtained for natural gas coming from Northern Germany or for imported natural gas are well consistent with actual measuring results. The model can therefore be applied as a rule for computing in a new technical recommendation and determine real gas factors whenever they are relevant to trading. The respective calculations must be preceded by a complete analysis characterizing the quality of gases. However, the new method allows for the alternative calculation of real gas factors on the basis of a small number of easily measurable factors (for example H/sub 0/, d, CO/sub 2/). This quality seams to be all the more attractive as it allows for an automatic translation of parametric sets at changing gas qualities which for the first time can manage without an expensive online gas chromatography or density translators, respectively.

Chronic lower respiratory disease is highly prevalent in the United States, and there remains a need for alternatives to lung transplant for patients who progress to end-stage lung disease. Portable or implantable gas oxygenators based on microfluidic technologies can address this need, provided they operate both efficiently and biocompatibly. Incorporating biomimetic materials into such devices can help replicate native gas exchange function and additionally support cellular components. In this work, we have developed microfluidic devices that enable blood gas exchange across ultra-thin collagen membranes (as thin as 2 μm). Endothelial, stromal, and parenchymal cells readily adhere to these membranes, and long-term culture with cellular components results in remodeling, reflected by reduced membrane thickness. Functionally, acellular collagen-membrane lung devices can mediate effective gas exchange up to ∼288 mL/min/m(2) of oxygen and ∼685 mL/min/m(2) of carbon dioxide, approaching the gas exchange efficiency noted in the native lung. Testing several configurations of lung devices to explore various physical parameters of the device design, we concluded that thinner membranes and longer gas exchange distances result in improved hemoglobin saturation and increases in pO2. However, in the design space tested, these effects are relatively small compared to the improvement in overall oxygen and carbon dioxide transfer by increasing the blood flow rate. Finally, devices cultured with endothelial and parenchymal cells achieved similar gas exchange rates compared with acellular devices. Biomimetic blood oxygenator design opens the possibility of creating portable or implantable microfluidic devices that achieve efficient gas transfer while also maintaining physiologic conditions.

Given appropriate pressure and temperature conditions the storage of natural gas in salt caverns can lead to the formation of gas hydrates in the producing well or aboveground operating facilities. This is attributable to the stored gas becoming more or less saturated with water vapour. The present contribution describes the humidity, pressure, and temperature conditions conducive to gas hydrate formation. It also deals with the reduction of the gas removal capacity resulting from gas hydrate formation, and possible measures for preventing hydrate formation such as injection of glycol, the reduction of water vapour absorption from the cavern sump, and dewatering of the cavern sump. (MSK) [Deutsch] Bei der Speicherung von Erdgas in Salzkavernen kann es unter entsprechenden Druck- und Temperaturverhaeltnissen zur Gashydratbildung in den Foerdersonden oder obertaegigen Betriebseinrichtungen kommen, weil sich das eingelagerte Gas mehr oder weniger mit Wasserdampf aufsaettigt.

Asia Gas Study

International Nuclear Information System (INIS)

1996-01-01

The Asia region has experienced a period of dynamic growth, both of economies and energy demand. The next fifteen years are likely to see further rapid economic growth in Asia. To fuel this growth energy consumption will also increase rapidly. Of all forms of energy, natural gas demand is likely to grow the fastest. The gas sector will face rapid and dramatic change, creating challenges for the governments of the region. Infrastructure, both for export and domestic consumption of gas, will need to expand significantly. Regional trade in natural gas could triple by 2010. Trade will continue to be dominated by liquefied natural gas (LNG) but pipeline exports will also grow rapidly. Investment needs will be large, putting pressure on governments to look for alternative funding mechanisms. As Asian gas transmission and distribution networks expand and become more interconnected, consumer choice becomes possible. How to encourage and regulate competition will become a vital policy question. As gas consumption increases both in absolute terms, and in terms of its share of energy consumption within particular sectors of the economy (for example, as a fuel for power generation), governments will need to give higher priority to policies dealing with gas security. This study examines the current and possible future role of natural gas in Asia. In particular, it examines in detail the relevant energy policies of six of the key gas producing and consuming economies in the region: Brunei-Darussalam, Chinese Taipei, Indonesia, the Republic of Korea, Malaysia and Thailand.

Ruppel, Carolyn D.

2018-01-17

Gas hydrate is a naturally occurring, ice-like substance that forms when water and gas combine under high pressure and at moderate temperatures. Methane is the most common gas present in gas hydrate, although other gases may also be included in hydrate structures, particularly in areas close to conventional oil and gas reservoirs. Gas hydrate is widespread in ocean-bottom sediments at water depths greater than 300–500 meters (m; 984–1,640 feet [ft]) and is also present in areas with permanently frozen ground (permafrost). Several countries are evaluating gas hydrate as a possible energy resource in deepwater or permafrost settings. Gas hydrate is also under investigation to determine how environmental change may affect these deposits.

1995-01-01

Under the A greement on Natural Gas Markets and Prices of October 1985, the Canadian federal government agreed to deregulate the price of natural gas and to allow a competitive gas market to develop. Several beneficial changes that have occurred as a result of the deregulation were described, including the Industrial Gas Users Association's (IGUA) view on the marketing and sale of natural gas by local gas distributor's (LDC) and the sale within the LDC franchise. IGUA's support for the separation between LDC distribution and LDC sales and marketing activities as the last step in deregulation process, was explained. Several arguments for the opposing view were also discussed. Recommendations were made for effective separation of LDC distribution and LDC sales/marketing activities

Geochemical evidence of water-soluble gas accumulation in the Weiyuan gas field, Sichuan Basin

Directory of Open Access Journals (Sweden)

Shengfei Qin

2016-01-01

Full Text Available At present, there are several different opinions on the formation process of the Weiyuan gas field in the Sichuan Basin and the source of its natural gas. In view of the fact that the methane carbon isotope of the natural gas in the Weiyuan gas field is abnormally heavy, the geologic characteristics of gas reservoirs and the geochemical characteristics of natural gas were first analyzed. In the Weiyuan gas field, the principal gas reservoirs belong to Sinian Dengying Fm. The natural gas is mainly composed of methane, with slight ethane and trace propane. The gas reservoirs are higher in water saturation, with well preserved primary water. Then, it was discriminated from the relationship of H2S content vs. methane carbon isotope that the heavier methane carbon isotope of natural gas in this area is not caused by thermochemical sulfate reduction (TSR. Based on the comparison of methane carbon isotope in this area with that in adjacent areas, and combined with the tectonic evolution background, it is regarded that the natural gas in the Weiyuan gas field is mainly derived from water-soluble gas rather than be migrated laterally from adjacent areas. Some conclusions are made. First, since methane released from water is carbon isotopically heavier, the water-soluble gas accumulation after degasification results in the heavy methane carbon isotope of the gas produced from Weiyuan gas field. Second, along with Himalayan movement, great uplift occurred in the Weiyuan area and structural traps were formed. Under high temperature and high pressure, the gas dissolved in water experienced decompression precipitation, and the released natural gas accumulated in traps, consequently leading to the formation of Weiyuan gas field. Third, based on calculation, the amount of natural gas released from water which is entrapped in the Weiyuan gas field after the tectonic uplift is basically equal to the proved reserves of this field, confirming the opinion of water

Catalytic hot gas cleaning of gasification gas

Energy Technology Data Exchange (ETDEWEB)

Simell, P. [VTT Energy, Espoo (Finland). Energy Production Technologies

1997-12-31

The aim of this work was to study the catalytic cleaning of gasification gas from tars and ammonia. In addition, factors influencing catalytic activity in industrial applications were studied, as well as the effects of different operation conditions and limits. Also the catalytic reactions of tar and ammonia with gasification gas components were studied. The activities of different catalyst materials were measured with laboratory-scale reactors fed by slip streams taken from updraft and fluid bed gasifiers. Carbonate rocks and nickel catalysts proved to be active tar decomposing catalysts. Ammonia decomposition was in turn facilitated by nickel catalysts and iron materials like iron sinter and iron dolomite. Temperatures over 850 deg C were required at 2000{sup -1} space velocity at ambient pressure to achieve almost complete conversions. During catalytic reactions H{sub 2} and CO were formed and H{sub 2}O was consumed in addition to decomposing hydrocarbons and ammonia. Equilibrium gas composition was almost achieved with nickel catalysts at 900 deg C. No deactivation by H{sub 2}S or carbon took place in these conditions. Catalyst blocking by particulates was avoided by using a monolith type of catalyst. The apparent first order kinetic parameters were determined for the most active materials. The activities of dolomite, nickel catalyst and reference materials were measured in different gas atmospheres using laboratory apparatus. This consisted of nitrogen carrier, toluene as tar model compound, ammonia and one of the components H{sub 2}, H{sub 2}O, CO, CO{sub 2}, CO{sub 2}+H{sub 2}O or CO+CO{sub 2}. Also synthetic gasification gas was used. With the dolomite and nickel catalyst the highest toluene decomposition rates were measured with CO{sub 2} and H{sub 2}O. In gasification gas, however, the rate was retarded due to inhibition by reaction products (CO, H{sub 2}, CO{sub 2}). Tar decomposition over dolomite was modelled by benzene reactions with CO{sub 2}, H

Advanced coal and/or biomass based power generation systems offer the potential for high efficiency electricity generation with minimum environmental impact. An important component for many of these advanced power generation cycles is the gas turbine, for which development of a combustion system to burn low calorific value coal derived fuel gas, at turbine inlet temperatures of typically 1 100 - 1 260 deg C and with minimum pollutant emissions, is a key issue. A phased combustor development programme is under-way burning low calorific value fuel gas (3.6 - 4.1 MJ/m{sup 3}) with low emissions, particularly NO{sub x} derived from fuel-bound nitrogen. The first and second phases of the combustor development programme have been completed. The first phase used a generic tubo-annular, prototype combustor based on conventional design principles. Combustor performance for this first prototype combustor was encouraging. The second phase assessed five design variants of the prototype combustor, each variant achieving a progressive improvement in combustor performance. The operating conditions for this assessment were selected to represent a particular medium sized industrial gas turbine operating as part of an Air Blown Gasification Cycle (ABGC). The test conditions assessed therefore included the capability to operate the combustor using natural gas as a supplementary fuel, to suit one possible start-up procedure for the cycle. The paper presents a brief overview of the ABGC development initiative and discusses the general requirements for a gas turbine operating within such a cycle. In addition, it presents full combustor performance results for the second phase of turbine combustor development and discusses the rationale for the progressive design modifications made within that programme. The strategy for the further development of the combustor to burn low calorific value fuel gas with very low conversion of fuel-bound nitrogen to NO{sub x} is presented. (orig.) 6 refs.

Natural Gas Liberalisation and Deregulation - The German Gas Industry's View

International Nuclear Information System (INIS)

Czernie, W.

2001-01-01

In Europe, the process of creating a single energy market is under way. The 1998 Gas Directive established an important date for the European gas industry. On 10 August 1998, ''Directive 98/30/EC of the European Parliament and of the Council of 22 June 1998 concerning common rules for the internal market in natural gas'' came into force. It had to be transposed into national law by the EU member states within two years, i.e. by 10 August 2000. The Directive is a cornerstone in establishing a competitive gas market in the European Union. It is the outcome of several years of negotiations and can be regarded as a compromise between the various interests. On the whole, it leaves EU member states with sufficient scope for adequately taking account of national characteristics in keeping with the principle of subsidiarity. The process of transposing the Gas Directive into the national law of individual EU member states is being closely followed by the European Commission. While acknowledging all the progress made in the single market process, the Commission still detects shortcomings in the implementation of the Gas Directive on the road to an actual single market. This is seen as a justification for new initiatives and intervention, even though the new political framework for the gas industry has not yet been tested in practice and been able to prove itself on a broad scale for any length of time. In the debate on liberalisation, tried-and-tested instruments of secure and market-oriented gas supply on the European continent long-term supply contracts with take-or-pay clauses and competitive oil-indexed gas prices have also come under scrutiny. However, even under the conditions of liberalisation, security of supply has to be achieved mainly by a balanced mix of supply sources and by long-term supply contracts, including competitive pricing as ensured by so-called oil indexing. In the further liberalisation of west European gas industries, it will be essential to ensure

A new method for calculating gas saturation of low-resistivity shale gas reservoirs

Full Text Available The Jiaoshiba shale gas field is located in the Fuling area of the Sichuan Basin, with the Upper Ordovician Wufeng–Lower Silurian Longmaxi Fm as the pay zone. At the bottom of the pay zone, a high-quality shale gas reservoir about 20 m thick is generally developed with high organic contents and gas abundance, but its resistivity is relatively low. Accordingly, the gas saturation calculated by formulas (e.g. Archie using electric logging data is often much lower than the experiment-derived value. In this paper, a new method was presented for calculating gas saturation more accurately based on non-electric logging data. Firstly, the causes for the low resistivity of shale gas reservoirs in this area were analyzed. Then, the limitation of traditional methods for calculating gas saturation based on electric logging data was diagnosed, and the feasibility of the neutron–density porosity overlay method was illustrated. According to the response characteristics of neutron, density and other porosity logging in shale gas reservoirs, a model for calculating gas saturation of shale gas was established by core experimental calibration based on the density logging value, the density porosity and the difference between density porosity and neutron porosity, by means of multiple methods (e.g. the dual-porosity overlay method by optimizing the best overlay coefficient. This new method avoids the effect of low resistivity, and thus can provide normal calculated gas saturation of high-quality shale gas reservoirs. It works well in practical application. This new method provides a technical support for the calculation of shale gas reserves in this area.

Experimental Study of Gas Explosions in Hydrogen Sulfide-Natural Gas-Air Mixtures

2014-01-01

Full Text Available An experimental study of turbulent combustion of hydrogen sulfide (H2S and natural gas was performed to provide reference data for verification of CFD codes and direct comparison. Hydrogen sulfide is present in most crude oil sources, and the explosion behaviour of pure H2S and mixtures with natural gas is important to address. The explosion behaviour was studied in a four-meter-long square pipe. The first two meters of the pipe had obstacles while the rest was smooth. Pressure transducers were used to measure the combustion in the pipe. The pure H2S gave slightly lower explosion pressure than pure natural gas for lean-to-stoichiometric mixtures. The rich H2S gave higher pressure than natural gas. Mixtures of H2S and natural gas were also studied and pressure spikes were observed when 5% and 10% H2S were added to natural gas and also when 5% and 10% natural gas were added to H2S. The addition of 5% H2S to natural gas resulted in higher pressure than pure H2S and pure natural gas. The 5% mixture gave much faster combustion than pure natural gas under fuel rich conditions.

De-linking oil and gas; The cost of Gulf gas; Middle East gas must look to Europe

Aissaoui, Ali; Jensen, Jim; Stern, Jonathan

1994-01-01

This item consists of letters in response to an article by Robert Mabro on the prospects for gas in North Africa and the Middle East. The first letter is concerned with the issue of de-linking oil and gas. It is argued that the introduction of an ecotax, far from its creators' intentions, may deter investment in the natural gas industry to the benefit of coal and oil producers, rather than promoting gas as the fuel which best protects the environment. The second writer points out the Middle East's geographical disadvantage in aiming to supply natural gas to Europe. While reserves are ample, they are also readily available closer to European consumers, and without extra transportation costs. Markets nearby are either already functioning or, in areas such as India or Pakistan, prohibitively expensive in terms of pipeline construction or other technology. The last author also argues for investment in large-scale pipeline projects in order to use the Middle Eastern gas reserves, but stresses the need for political and security problems to be addressed at the same time.

Gas utilization technologies

One of the constant challenges facing the research community is the identification of technology needs 5 to 15 years from now. A look back into history indicates that the forces driving natural gas research have changed from decade to decade. In the 1970s research was driven by concerns for adequate supply; in the 1980s research was aimed at creating new markets for natural gas. What then are the driving forces for the 1990s? Recent reports from the natural gas industry have helped define a new direction driven primarily by market demand for natural gas. A study prepared by the Interstate Natural Gas Association of America Foundation entitled ''Survey of Natural Research, Development, and Demonstration RD ampersand D Priorities'' indicated that in the 1990s the highest research priority should be for natural gas utilization and that technology development efforts should not only address efficiency and cost, but environmental and regulatory issues as well. This study and others, such as the report by the American Gas Association (A.G.A.) entitled ''Strategic Vision for Natural Gas Through the Year 2000,'' clearly identify the market sectors driving today's technology development needs. The biggest driver is the power generation market followed by the industrial, transportation, appliance, and gas cooling markets. This is best illustrated by the GRI 1994 Baseline Projection on market growth in various sectors between the year 1992 and 2010. This paper highlights some of the recent technology developments in each one of these sectors

Natural gas from the Shatlyk gas field in the Kara Kum Desert, Turkmenia, U.S.S.R., will soon be available to the European section of the U.S.S.R. with the recent completion of the 291-mi Shatlyk-Khiva gas pipeline and the completion of all associated production units by the end of the year. The gas field, with explored reserves of (1.5 trillion m/sup 3/), is expected to be producing (100 million m/sup 3//day) at the end of 1975. Diagonal profiling was used in the exploration stage to reduce the number of boreholes required from 16 to 11, saving about $6.7 million (5 million rubles) and cutting the exploration time by almost 2 y. Most of the boreholes, drilled within the contour of the gas-bearing structure, can be used for gas production. The gas, produced at 2352 psi and 205/sup 0/F, is cooled to 113/sup 0/F, stripped of condensate and moisture, metered, and treated before transmission.

Purpose: When injecting gas during plasma discharge, to prevent erronous operation of the piezoelectric valves due to vibrations and to inject gas into the vacuum vessel by accurately controlling gas flow. Constitution: The piezoelectric valve designed to control the flow of gas when charging vacuum vessels is installed between the vacuum vessel and the gas cylinder and a pulse voltage generator to control the valve (open/close) and the reverse voltage generator to apply a reverse current to the valve element are also provided. When a voltage is applied to the piezoelectric element, the piezoelectric element bends. However, when the polarity is changed, the direction of the bend is also reversed. The seat portion is pressed in proportion to the degree of bending. When gas is injected while plasma is being discharged, the gap created, due to vibrations, between the piezoelectric element and the sealing material is prevented by the application of a reverse current. This allows precise control of the gas injection volume as well as the injection interval. This assures maintenance of precise test conditions when testing thermonuclear devices. (Horiuchi, T.)

The EIA annual reserves report series is the only source of comprehensive domestic proved reserves estimates. This publication is used by the Congress, Federal and State agencies, industry, and other interested parties to obtain accurate estimates of the Nation`s proved reserves of crude oil, natural gas, and natural gas liquids. These data are essential to the development, implementation, and evaluation of energy policy and legislation. This report presents estimates of proved reserves of crude oil, natural gas, and natural gas liquids as of December 31, 1995, as well as production volumes for the US and selected States and State subdivisions for the year 1995. Estimates are presented for the following four categories of natural gas: total gas (wet after lease separation), nonassociated gas and associated-dissolved gas (which are the two major types of wet natural gas), and total dry gas (wet gas adjusted for the removal of liquids at natural gas processing plants). In addition, reserve estimates for two types of natural gas liquids, lease condensate and natural gas plant liquids, are presented. Also included is information on indicated additional crude oil reserves and crude oil, natural gas, and lease condensate reserves in nonproducing reservoirs. A discussion of notable oil and gas exploration and development activities during 1995 is provided. 21 figs., 16 tabs.

Natural gas pricing

Natural gas pricing is the heart and soul of the gas business. Price specifically affects every phase of the industry. Too low a price will result in short supplies as seen in the mid-1970s when natural gas was scarce and in tight supply. To fully understand the pricing of this energy commodity, it is important to understand the total energy picture. In addition, the effect and impact of world and US economies, and economics in general are crucial to understanding natural gas pricing. The purpose of this presentation will be to show the parameters going into US natural gas pricing including the influence of the many outside industry factors like crude oil and coal pricing, market drivers pushing the gas industry, supply/demand parameters, risk management for buyers and sellers, and other elements involved in pricing analysis

This paper is the press release of the talk given at the `Gaz de France scientific meeting with the press` by P. Gadonneix, chairman of Gaz de France company, on October 7, 1998. The aim of this talk concerns the new French and European supply link for bringing natural gas from the Norwegian North Sea fields. This new supply link is the first direct link between Norway and France and the NorFra gas pipeline which brings natural gas from the North Sea to France is the longest offshore pipeline in the world. The `Artere des Hauts de France` pipeline (the largest diameter gas pipeline ever laid in France) is devoted to the transfer of natural gas from Dunkerque to the Gournay-sur-Aronde underground storage site. This paper describes successively: the French European gas supply hub, the NorFra project, the Artere des Hauts de France pipeline, the network performance research, the safety and quality guaranties, the reduction of overland natural gas transmission costs (improvement of pipe-laying techniques and optimization of line route and welding operations), the specific techniques used for road and river crossing (micro-tunnel digging, river-crossing ditches) and for anchoring (buoyancy compensation). Finally, the environmental impact of the laying operations is briefly described. (J.S.)

Despite completing 8,900 gas wells in year 2000, the deliverability of natural gas out of the Western Canadian Sedimentary Basin (WCSB) was stagnant which has left many analysts wondering whether the basin has reached its limit. It also leaves many wondering if gas producers will be able to meet the strong demand for natural gas in the future. Nearly all new electrical generation being built in the U.S. is gas-based due to strict new environmental standards limiting the growth in hydro and coal-powered generation. Any future coal plants will use gasification technology and combined cycle turbines. Combined cycle turbines developed by Boeing and Lockheed are more efficient than combustion turbines, making gas more competitive with fuel alternatives. The lack of growth in natural gas supply has left storage levels near record lows. Demand is expected to increase in 2001 by 3.2 per cent to 23 trillion cubic feet in the U.S. Longer term, major new reserves must be brought on stream to meet this demand. It was noted that the easy discoveries within the WCSB have been made. The new plays are smaller, more technically complex and expensive which suggests that more investment is needed in training geologists, geophysicists and petroleum engineers to find new reserves. The Canadian Energy Research Institute agrees that there is enough gas in Alberta and British Columbia to meet current demands but efforts must shift towards drilling in the foothills front and northwest regions of Alberta to increase deliverability. Brief notes on several gas finds by various oil and gas companies in the area were presented. The article also discussed the huge untapped potential of northern reserves. Analysts have noted 44 Tcf of proven reserve, with a potential of 165 Tcf. In addition, new pipelines from the Alaskan North Slope and the Mackenzie Delta could transport nearly 2 Tcf annually to market. Wells drilled by Chevron and Paramount at Fort Liard in 1999 initially flowed at rates up to

Consumersfirst Ltd. is reacting to deregulation with a massive advertising campaign. The gas utility is owned by Consumers Gas Energy Inc., and is struggling to hold onto its 35 per cent share of Ontario`s two million residential natural gas buyers. An industry analyst pointed out that deregulation could mean that Consumers` Gas has much to lose: customers, market share, control of the assets and control of the process. The Ontario Energy Board (OEB) however, had specified that Consumersfirst is not to proceed with paperwork to sign up new customers until the OEB issues a draft code-of-conduct that would prevent cross-subsidizing between regulated franchise holders. This has now been done, and several heavyweights such as Calgary-based Suncor Energy Inc., Union Gas of Chatham, Ontario, and the US-based Enron Corp. of Houston, have started campaigns to sign up potential consumers. It is predicted that brand loyalty will be a factor, but in the end, like long distance telephone rates, it will all come down to pricing, and a winning formula is not easy to find.

In 1992, over 86% of Canadian propane and 70% of Canadian butane production originated in gas plants. Propane and butane production not recovered at gas plants is recovered in other processing facilities, primarily refineries and heavy oil upgraders. As a result, supplies of both products are largely tied to natural gas production, and the outlook for natural gas therefore provides the basis for any discussion on the outlook for gas processing and NGL industry infrastructure. The paper discusses gas processing, economies of scale, NGL supply, expected declines, industry structure and infrastructure, the two major centers of the Canadian NGL industry, new shippers, and required pipeline expansion

The origin of gas in the Changxing–Feixianguan gas pools in the Longgang gas field in the Sichuan Basin, China

Directory of Open Access Journals (Sweden)

Shengfei Qin

2016-10-01

Full Text Available In this paper, the origin of natural gas in the formations of the Changxing–Feixianguan within the Longgang gas field was studied in detail using geochemical methods. The gas discovered has a very high dryness coefficient, yet low ethane and other less heavy hydrocarbons content. Apart from a small amount of N2 and CO2 gasses it generally contains H2S. In the field location, the Changxing–Feixianguan formations itself does not have a hydrocarbon generation potential. Nearing the edge of the Kaijiang-Liangping Trough, there developed the Dalong Formation. However, it also has a very low TOC content in the area of the Longgang gas field, and it cannot act as an effective source rock. The geochemistry of natural gas is much different from the gasses generated by the Silurian and Cambrian source rocks. Therefore, it is impossible that the gas in the Longgang gas field is from the Silurian and Cambrian source rocks. Gas reservoirs generally contain bitumen which is considered a product of crude oil cracking. The carbon isotope fractionation between the bitumen and methane is not distinct, and it indicates that the gas is not directly from oil cracking. The carbon of methane and ethane has isotopically less negative value, which is considered to be in a high-overmature coal-formed gas, mainly from the Longtan Formation coal measures. In comparison to the gas from high overmature stage obtained from the Xujiahe coal measure source rock in the Western Sichuan Depression. The methane in the Longgang gas field has abnormal less negative carbon isotopic value. It is due to the superposition of these two factors together: higher evolution of source rocks and mixing of gas degassing from the water. It is not caused by TSR that most researchers believed at present because the methane carbon isotopic values have no relationship with H2S content.

Response characteristics of vibration-sensitive interneurons related to Johnston's organ in the honeybee, Apis mellifera.

Honeybees detect airborne vibration by means of Johnston's organ (JO), located in the pedicel of each antenna. In this study we identified two types of vibration-sensitive interneurons with arborizations in the primary sensory area of the JO, namely, the dorsal lobe-interneuron 1 (DL-Int-1) and dorsal lobe-interneuron 2 (DL-Int-2) using intracellular recordings combined with intracellular staining. For visualizing overlapping areas between the JO sensory terminals and the branches of these identified interneurons, the three-dimensional images of the individual neurons were registered into the standard atlas of the honeybee brain (Brandt et al. [2005] J Comp Neurol 492:1-19). Both DL-Int-1 and DL-Int-2 overlapped with the central terminal area of receptor neurons of the JO in the DL. For DL-Int-1 an on-off phasic excitation was elicited by vibrational stimuli applied to the JO when the spontaneous spike frequency was low, whereas tonic inhibition was induced when it was high. Moreover, current injection into a DL-Int-1 led to changes of the response pattern from on-off phasic excitation to tonic inhibition, in response to the vibratory stimulation. Although the vibration usually induced on-off phasic excitation in DL-Int-1, vibration applied immediately after odor stimulation induced tonic inhibition in it. DL-Int-2 responded to vibration stimuli applied to the JO by a tonic burst and were most sensitive to 265 Hz vibration, which is coincident with the strongest frequency of airborne vibrations arising during the waggle dance. These results suggest that DL-Int-1 and DL-Int-2 are related to coding of the duration of the vibration as sensed by the JO. Copyright 2009 Wiley-Liss, Inc.

Economic studies on simulated gas hydrate reservoirs have been compiled to estimate the price of natural gas that may lead to economically viable production from the most promising gas hydrate accumulations. As a first estimate, $CDN2005 12/Mscf is the lowest gas price that would allow economically viable production from gas hydrates in the absence of associated free gas, while an underlying gas deposit will reduce the viability price estimate to $CDN2005 7.50/Mscf. Results from a recent analysis of the simulated production of natural gas from marine hydrate deposits are also considered in this report; on an IROR basis, it is $US2008 3.50-4.00/Mscf more expensive to produce marine hydrates than conventional marine gas assuming the existence of sufficiently large marine hydrate accumulations. While these prices represent the best available estimates, the economic evaluation of a specific project is highly dependent on the producibility of the target zone, the amount of gas in place, the associated geologic and depositional environment, existing pipeline infrastructure, and local tariffs and taxes. ?? 2009 Elsevier B.V.

PURPOSE: To compare gas-foveal contact in face-down positioning (FDP) and nonsupine positioning (NSP), to analyze causes of gas-foveal separation and to determine how gas-foveal contact affects clinical outcome after idiopathic macular hole repair. METHODS: Single center, randomized controlled...... study. Participants with an idiopathic macular hole were allocated to either FDP or NSP. Primary outcome was gas-foveal contact, calculated by analyzing positioning in relation to intraocular gas fill. Positioning was measured with an electronic device recording positioning for 72 hours postoperatively....... RESULTS: Positioning data were available for 33/35 in the FDP group and 35/37 in the NSP group, thus results are based on 68 analyzed participants. Median gas-foveal contact was 99.82% (range 73.6-100.0) in the FDP group and 99.57% (range 85.3-100.0) in the NSP group (P = 0.22). In a statistical model...

U.S. gas

Parent, L.

1991-01-01

This paper reports that U.S. gas producers won't see much price relief in 1991, barring a Persian Gulf war that interrupts crude supply which might be replaced by gas on short notice. Besides the current supply surplus, natural gas futures have added yet another dimension to the process of setting gas prices. Spectators (read speculators) having no intention of ever buying one cu ft of gas now have a hand in setting the forward price of gas. That doesn't necessarily mean something bad; it simply means that there is a new game with new rules and new players. All things considered, look for an average spot price of $1.70 this year. Exploration should pick up modestly, but production from conventional sources is expected to decline slightly in the '90s. Technological developments that enhance deliverability and reduce finding costs will moderate the decline, but not halt it

Natural gas outlook

An overview of natural gas markets in Canada and in the United States was provided. The major factors that determine the direction of natural gas prices were depicted graphically. Price volatility has decreased in recent months. As expected, April through November total energy consumption reached historically high levels. Demand for natural gas during the summer of 1997 was not as strong as anticipated. Nuclear energy appears to be on the slippery slope, with natural gas-driven electricity projects to fill the void. Hydroelectricity had a strong showing in 1997. Prospects are less bright for 1998 due to above average temperatures. Canadian natural gas export capacity has increased 5.5 times between 1986 and estimated 1999 levels. Despite this, in 1997, deliveries to the United States were marginally behind expectations. Natural gas consumption, comparative fuel prices, natural gas drilling activity, natural gas storage capacity, actual storage by region, and average weekly spot natural gas prices, for both the U. S. and Canada, were also provided. With regard to Canada, it was suggested that Canadian producers are well positioned for a significant increase in their price realization mostly because of the increase in Canada's export capacity in 1997 (+175 Mmcf/d), 1998 (1,060 Mmcf/d) and potentially in 1999 or 2000, via the Alliance Pipeline project. Nevertheless, with current production projections it appears next to impossible to fill the 10.9 Bcf/d of export capacity that will be potentially in place by the end of 1999. tabs., figs

Wet gas sampling

Energy Technology Data Exchange (ETDEWEB)

Welker, T.F.

1997-07-01

The quality of gas has changed drastically in the past few years. Most gas is wet with hydrocarbons, water, and heavier contaminants that tend to condense if not handled properly. If a gas stream is contaminated with condensables, the sampling of that stream must be done in a manner that will ensure all of the components in the stream are introduced into the sample container as the composite. The sampling and handling of wet gas is extremely difficult under ideal conditions. There are no ideal conditions in the real world. The problems related to offshore operations and other wet gas systems, as well as the transportation of the sample, are additional problems that must be overcome if the analysis is to mean anything to the producer and gatherer. The sampling of wet gas systems is decidedly more difficult than sampling conventional dry gas systems. Wet gas systems were generally going to result in the measurement of one heating value at the inlet of the pipe and a drastic reduction in the heating value of the gas at the outlet end of the system. This is caused by the fallout or accumulation of the heavier products that, at the inlet, may be in the vapor state in the pipeline; hence, the high gravity and high BTU. But, in fact, because of pressure and temperature variances, these liquids condense and form a liquid that is actually running down the pipe as a stream or is accumulated in drips to be blown from the system.

Minas Gerais is a State where there is no production of natural gas. Aiming to increase the consumption of natural gas in Minas Gerais, PETROBRAS increase the network of gas natural distribution in the State of Minas Gerais and the State concessionaire (GASMIG) installed the Project of Natural Gas Valley. The case study is associated to an enterprise that firmed contract for supplying of natural gas. The fuel to be substituted is the Liquefied Petroleum Gas and the results of the substitution were shown. The advantages of the substitution were related to costs, and environmental aspects with the reduction of CO{sub 2} production. The natural gas contains a lower content of impurities and is operated with higher safety than the petroleum liquefied gas. (author)

Natural gas supply in Denmark - A model of natural gas transmission and the liberalized gas market

International Nuclear Information System (INIS)

Bregnbaek, L.

2005-01-01

In the wake of the liberalization of European energy markets a large area of research has spawned. This area includes the development of mathematical models to analyze the impact of liberalization with respect to efficiency, supply security and environment, to name but a few subjects. This project describes the development of such a model. In Denmark the parallel liberalization of the markets of natural gas and electricity and the existence of an abundance of de-centralized combined heat and power generators of which most are natural gas fired, leads to the natural assumption that the future holds a greater deal of interdependency for these markets. A model is developed describing network flows in the natural gas transmission system, the main arteries of natural gas supply, from a technical viewpoint. This yields a technical bounding on the supply available in different parts of the country. Additionally the economic structure of the Danish natural gas market is formulated mathematically giving a description of the transmission, distribution and storage options available to the market. The supply and demand of natural gas is put into a partial equilibrium context by integrating the developed model with the Balmorel model, which describes the markets for electricity and district heat. Specifically on the demand side the consumption of natural gas for heat and power generation is emphasized. General results and three demonstration cases are presented to illustrate how the developed model can be used to analyze various energy policy issues, and to disclose the strengths and weaknesses in the formulation.

Today's gas glut and yesterday's contracts: the British Gas predicament

International Nuclear Information System (INIS)

Stoppard, M.

1996-10-01

Deregulation of the gas and electricity industries has led to a state of pronounced oversupply in the UK gas market. The effects of this oversupply became apparent during the course of 1995 and took two forms. Firstly, there was the emergence of a market for the short-term trading of gas. The price levels in this market collapsed in the first half of 1995 opening up a price gap between ''spot'' and contract gas. Secondly, some contract gas was paid for but was not produced, so that delivery to market was indefinitely postponed: there was a run-up in inventory - or ''take-or-pay'' - gas levels, as a form of keeping supply off the market. Oversupply has exerted great pressure on a number of market participants throughout the gas chain who remain locked into purchase agreements for volumes which have no market outlet, and at prices above market levels. The rally in spot price levels experienced since the second quarter of 1996 has eased pressure within the market but has not removed the fundamental strains. The market is expected to remain in oversupply at least up to the end of 1998. Keen price competition may not clear the market even at discount prices, so that shut-in of production capacity is likely. The consequent build-up in take-or-pay levels will continue through the period, although at steadily declining rates, and there is little scope prior to 1999 for the industry as a whole to offload this inventory gas on the market.

Gas-partitioning tracer test to qualify trapped gas during recharge

Science.gov (United States)

Heilweil, Victor M.; Kip, Solomon D.; Perkins, Kim S.; Ellett, Kevin M.

2004-01-01

Dissolved helium and bromide tracers were used to evaluate trapped gas during an infiltration pond experiment. Dissolved helium preferentially partitioned into trapped gas bubbles, or other pore air, because of its low solubility in water. This produced observed helium retardation factors of as much as 12 relative to bromide. Numerical simulations of helium breakthrough with both equilibrium and kinetically limited advection/dispersion/retardation did not match observed helium concentrations. However, better fits were obtained by including a decay term representing the diffusive loss of helium through interconnected, gas-filled pores. Calculations indicate that 7% to more than 26% of the porosity beneath the pond was filled with gas. Measurements of laboratory hydraulic properties indicate that a 10% decrease in saturation would reduce the hydraulic conductivity by at least one order of magnitude in the well-sorted sandstone, but less in the overlying soils. This is consistent with in situ measurements during the experiment, which show steeper hydraulic gradients in sandstone than in soil. Intrinsic permeability of the soil doubled during the first six months of the experiment, likely caused by a combination of dissolution and thermal contraction of trapped gas. Managers of artificial recharge basins may consider minimizing the amount of trapped gas by using wet, rather than dry, tilling to optimize infiltration rates, particularly in well-sorted porous media in which reintroduced trapped gas may cause substantial reductions in permeability. Trapped gas may also inhibit the amount of focused infiltration that occurs naturally during ephemeral flood events along washes and playas.

A series of overhead viewgraphs accompanied this presentation which focused on various aspects of the natural gas industry in Mexico. Some of the viewgraphs depicted statistics from 1998 regarding natural gas throughput from various companies in North America, natural gas reserves around the world, and natural gas reserves in Mexico. Other viewgraphs depicted associated and non-associated natural gas production from 1988 to 1998 in million cubic feet per day. The Burgos Basin and the Cantarell Basin gas production from 1997 to 2004 was also depicted. Other viewgraphs were entitled: (1) gas processing infrastructure for 1999, (2) cryogenic plant at Cd. PEMEX, (3) average annual growth of dry natural gas production for 1997-2004 is estimated at 5.2 per cent, (4) gas flows for December 1998, (5) PGPB- interconnect points, (6) U.S. Mexico gas trade for 1994-1998, (7) PGPB's interconnect projects with U.S., and (8) natural gas storage areas. Technological innovations in the industry include more efficient gas turbines which allow for cogeneration, heat recovery steam generators which reduce pollutant emissions by 21 per cent, cold boxes which increase heat transfer efficiency, and lateral reboilers which reduce energy consumption and total costs. A pie chart depicting natural gas demand by sector shows that natural gas for power generation will increase from 16 per cent in 1997 to 31 per cent in 2004. The opportunities for cogeneration projects were also reviewed. The Comision Federal de Electricidad and independent power producers represent the largest opportunity. The 1997-2001 investment program proposes an 85 per cent sulphur dioxide emission reduction compared to 1997 levels. This presentation also noted that during the 1998-2001 period, total ethane production will grow by 58 tbd. 31 figs

The Russian gas industry

1997-01-01

The Russian Federation holds the world's largest proven natural gas reserves, and produces more natural gas than any other nation. Russian exports of gas to Europe and the other nations of the Commonwealth of Independent States (CIS) have a significant impact on natural gas markets throughout Europe and Asia. The aim of this three part study is to inform the international energy and investment community about the current status of the Russian gas industry and the prospects for its future development through 2010. It is also intended to provide an opportunity for the appropriate authorities in the Russian Federation to assess the needs of the industry and to consider areas for possible collaboration with the international investment community and international organizations in a rapidly changing economic and business environment. The study was prepared by the Energy Branch of the United Nations Department for Development Support and Management Services (UN/DDSMS). It was financed by the United Nations Development Programme (UNDP). Part I describes Russian gas reserves and potential resources, and overviews the country's gas producing, pipeline and distribution industries. Additionally, it summarizes the markets for Russian natural gas including domestic and external markets. It discusses the primary economics and potential factors that currently impact the Russian gas industry during the Federation's transition toward a market economy. Part II highlights possible directions for the development of the Russian gas resource base, including upstream gas production and downstream marketing in five-, ten- and fifteen-year time frames. It projects export opportunities for Russian Federation gas and evaluates the options for shaping regional and international markets. Part III addresses the legal and regulatory framework and fiscal regime of the Russian gas industry. It also reviews the major investment requirements and the equipment and training needs of the Russian gas

The second Federal German experts' meeting on Gas Consulting from 2nd to 5th June 1981 in Saarbruecken documents the importance attached by the gas industry to a qualified energy consulting. The consumers are informed of natural gas by country-wide and regional PR- and marketing activities. This information is the basis for sales promotion measures in the regional and local sphere. All communicative measures end with the consulting. It is the most important sales-political instrument which helps the supply companies to win interested and informed customers. The action gas consulting shows possibilities of how to effect an advisory service in cooperation between Information on Natural Gas and local suppliers.

Demand for natural gas in Thailand is increasing significantly as the Electricity Generating Authority of Thailand and the independent private power producers (IPPs) switch from oil to gas to fire their power stations in line with Government policy to reduce oil imports and use more gas from the Gulf of Thailand. The Petroleum Authority of Thailand (PTT) has the sole right to buy and sell natural gas and other petroleum products in Thailand. According to PTT, the surge in demand for natural gas in the first half of 2001 was matched by a fall in demand for refined oil products. The PTT has received Government approval to convert to a limited company ready for listing on the Thai Stock Exchange. This is expected to further increase gas consumption. Details of gas sales to power generation and other industrial sectors by PTT and Unocal, Thailand's largest producer, are given. PTT operations include work to extend its gas pipeline transmission system. A number of new pipeline schemes are planned, including one across southern Thailand to transfer offshore gas from the Joint Development Area gas field owned by Thailand and Malaysia. This has encountered protests over the proposed plant and pipeline route

A gas sensor includes an in-fiber resonant wavelength device provided in a fiber core at a first location. The fiber propagates a sensing light and a power light. A layer of a material is attached to the fiber at the first location. The material is able to absorb the gas at a temperature dependent gas absorption rate. The power light is used to heat the material and increases the gas absorption rate, thereby increasing sensor performance, especially at low temperatures. Further, a method is described of flash heating the gas sensor to absorb more of the gas, allowing the sensor to cool, thereby locking in the gas content of the sensor material, and taking the difference between the starting and ending resonant wavelengths as an indication of the concentration of the gas in the ambient atmosphere.

Preliminary report on the economics of gas production from natural gas hydrates

International Nuclear Information System (INIS)

Walsh, M.; Wilson, S.; Patil, S.; Moridis, G.; Boswell, R.; Koh, C.; Sloan, D.

2008-01-01

Gas hydrates are solid crystalline compounds in which gas molecules reside inside cages that are formed by hydrogen-bonded water molecules in a crystal lattice. At particularly low temperatures and high pressures, a guest molecule will combine with water to form gas hydrates. Gas hydrates are found in two different settings in which the temperature and pressure conditions are suitable for their existence, notably in Arctic permafrost regions and below the seafloor. Because of the size of this possible future resource, if any of the gas in hydrates can be proven to be economically recoverable, then production from gas hydrates could become an important portion of the world's energy portfolio as demand for natural gas increases along with the technology to compress and distribute natural gas to distant markets. This paper presented a compilation of economic research that was conducted on the resource potential of gas hydrates. The paper reported a preliminary estimate of the price of natural gas that may lead to economically-viable production from North American Arctic region hydrates. The paper also discussed the implications of a recent study on the production of class 3 marine hydrate deposits from the Gulf of Mexico. The state of the art technologies and methods in hydrate reservoir modeling and hydrate reservoir production and petrophysical testing were also discussed. It was concluded that the somewhat optimistic results presented in this report should be interpreted with caution, however, the economically-viable gas production from hydrates was not an unreasonable scenario. 23 refs., 2 tabs., 10 figs

Selling gas, selling services

Traditionally, the commercial activities of gas companies have been limited almost exclusively to the sale of gas. However, several socioeconomic factors specific to the gas industry, such as increasing customer expectations, competition between gas operators, a growing emphasis on services in many companies and the opening of public monopolies to competition, will bring inevitable change. Moreover, these developments coincide with imminent gas market opening. In response to the changing situation, the gas industry will seek to develop a range of multi-service offers, probably through external partnerships. (authors)

Gage for gas flow measurement especially in gas-suction pipes

The gage utilizes the differential pressure given by a differential pressure producer to generate, in a bypass, a partial gas flow measured by means of a direct-reading anemometer of windmill type. The partial gas flow is generated between pressure pick-up openings in the gas-suction pipe in front of a venturi insert and pressure pick-up openings at the bottleneck of the venturi insert. The reading of the anemometer is proportional to the main gas flow and independent of the variables of state and the properties of the gases to be measured. (RW) [de

The halogens of chlorine and fluorine greatly influence the corrosion speed of metal materials. If small quantities of chlorinated and/or fluorinated hydrocarbons are present in fuel gas like in landfill gas, they must not result in enhanced corrosion of gas appliances. Data from literature and the initial results of tests run by the author indicate that quantities at about 10 mg/cbm (in terms of chlorine) can be assumed not to cause any noticeable acceleration of corrosion speed.

Gas to Power in China. Gas-fired Power in China. Clearing the policy bottleneck

International Nuclear Information System (INIS)

Chen, Xavier

2005-12-01

Policy for gas-fired power is the single most serious and common issue that needs urgent resolution for all China's current and future gas projects, including LNG projects. This was the main conclusion of a national seminar on gas industry development policy that was held in July 2004. At the time of writing this paper, such a policy is still missing. In order to reduce pollution, improve energy security and meet the needs of the ever-growing economy for high-quality energies, the Chinese government has declared its firm intention to develop a natural gas market. The official target is to develop a gas market of 200 bcm/a by 2020, five times of the current size of around 40 bcm/a. Domestic supply is expected to provide 120 bcm/a, with the rest (80 bcm/a) by gas imports either in the form of piped gas or LNG. Gas-fired power generation plays a critical role in developing a sizeable gas market, especially for large-scale pipeline and LNG projects. Similar to the Guangdong and Fujian LNG projects where gas-fired power accounts for approximately 60% and 70% respectively of the first phase gas volume, each of the proposed LNG projects has allocated a large portion of the gas off-take volume to the power sector. In addition to the first two commercial CCGT plants that were commissioned in 2005, there are over 20 projects totalling 18 GW of capacity under construction. By 2020, China's planners foresee a total gas-fired power capacity of 60 GW, accounting for around 6% of the total installed capacity in the country. Despite these impressive projections, gas-fired power faces significant uncertainties in China: (1) there is an ongoing debate on whether China should develop gas-fired power, given the relative scarcity and higher cost of gas; (2) high gas prices and imported equipment limit the competitiveness of gas-fired power relative to a coal-fired one; (3) it lacks policy support. For the moment, gas-fired power plants are required to participate in a yet

Northern Ireland gas industry

Throughout Northern Ireland the production of town gas is derived from hydrocarbon feedstocks. In the larger undertakings in Northern Ireland the feedstock is light distillate; a light petroleum feedstock which is a crude gasoline comprised mainly of pentanes, reformed in catalytic plants. The remaining gas undertakings produce a liquefied petroleum gas (LPG)/air mixture using a mixture of either butane or propane and air. The individual gas units and the type of reforming feedstock are shown. A review of the oil-dependence of town gas and electricity production in Northern Ireland has been considered and is mainly responsible for the high fuel prices experienced in the community. A detailed description of the reforming process has been described, and considerable efforts have been made to optimize the process. In spite of substantial economic savings being made on the processing unit, the gas industry is very susceptible to the changes in oil prices which have escalated rapidly in recent years. The difference in gas prices between the United Kingdom and Northern Ireland indicates that North Sea gas would offer major economic benefits to the gas industry in Northern Ireland, which is operating at a substantial loss at the moment. The industrial concerns, which are dependent on gas and therefore paying high fuel costs, suffer in competition with outside companies. The injection of a moderately cheap natural gas supply to the community may encourage industrial expansion and provide work in a high unemployment area. Although substantial costs must be incurred in distribution pipelines and burner conversions if Northern Ireland changes to natural gas, there appears to be a strong case to introduce North Sea gas in the near future.

The purpose of this paper is to present gas allocation plans developed for PETROBRAS Gas and Power Sector, considering failure to supply scenarios that could occur along gas supply network. Those scenarios, as well as the associated contingency plans, were identified and validated by an experienced team, composed by engineers and operators from different PETROBRAS sectors. The key issue of concern was the anticipation of possible undesired scenarios that could imply on contract shortfalls, the evaluation of possible maneuvers, taking into account best gas delivery allocation. Different software were used for the simulation of best gas supply allocation and for the verification of delivery pressure and conditions for final consumers. The ability of being capable of dealing with undesired or crisis scenarios, based on suitable anticipation levels, is, nowadays, a highly valuable attribute to be presented by competitive corporations, for best crisis management and prompt recovery response. Those plans are being used by Gas and Power Gas Operation Control Centre and as an input for reliability modeling of gas supply chain. (author)

Endogenous gas formation--an in vitro study with relevance to gas microemboli during cardiopulmonary bypass.

Lindholm, Lena; Engström, Karl Gunnar

2012-09-01

Gas embolism is an identified problem during cardiopulmonary bypass (CPB). Our aim was to analyze the potential influence from gas solubility based on simple physical laws, here called endogenous gas embolism. Gas solubility decreases at higher temperature and gas bubbles are presumably formed at CPB warming. An experimental model to measure gas release was designed. Medium (water or blood retrieved from mediastinal drains, 14.6 mL) was incubated and equilibrated with gas (air, 100% oxygen, or 5% carbon dioxide in air) at low temperature (10 degrees C or 23 degrees C). At warming to 37 degrees C, gas release was digitally measured. Also, the effect of fluid motion was evaluated. At warming, the medium became oversaturated with dissolved gas. When fluid motion was applied, gas was released to form bubbles. This was exemplified by a gas release of .45% (.31/.54, medians and quartile range, volume percent, p = .007) and 1.26% (1.14/ 1.33, p = .003) when blood was warmed from 23 degrees C or 10 degrees C to 37 degrees C, respectively (carbon dioxide 5% in air). Consistent findings were seen for water and with the other types of gas exposure. The theory of endogenous gas embolization was confirmed with gas being released at warming. The endogenous gas formation demonstrated a dynamic pattern with oversaturation and with rapid gas released at fluid motion. The gas release at warming was substantial, in particular when the results were extrapolated to full-scale CPB conditions. The interference from endogenous gas formation should be considered in parallel to external sources of gas microemboli. cardiopulmonary bypass, gas embolization, microemboli, gas solubility, temperature.

The Chinese Government intends to totally prohibit the combustion of coal as is in 2000 onward to deal with environmental problems. To attain the coal, however, it will have to develop technologies for high-efficiency coal utilization, coal pulverization for power generation, and power generation not dependent on coal. Qatar and India signed a letter confirming their intention to enhance cooperation in the oil and gas sectors. It is predicted that natural gas consumption in the United States will renew its maximum record in 1998. In the last half of this year, Venezuela will open its natural gas distribution and transportation sectors to foreign investors. Itohchu Oil Exploration Co., Ltd., operated by Itohchu Corporation for natural resources exploration, won the first success in a foreign capital-led trial drilling in the Caspian Sea off Azerbaijan. Six U.S. corporations plan to participitate in a project of constructing an LNG receiving base and distribution network in Lebanon. Norway is making efforts to increase its sale of gas to the British market despite there are great quantities of inexpensive gas in Britain. Britain will put off the complete liberalization of electric retailing scheduled to be effectuated in April this year until September. The investment in the oil and gas upstream sectors across the world in 1997 is found to be two times larger than that of 1990

A gas-path leakage seal is described for generally sealing a gas-path leakage-gap between spaced-apart first and second members of a gas turbine (such as combustor casing segments). The seal includes a generally imperforate foil-layer assemblage which is generally impervious to gas and is located in the leakage-gap. The seal also includes a cloth-layer assemblage generally enclosingly contacting the foil-layer assemblage. In one seal, the first edge of the foil-layer assemblage is left exposed, and the foil-layer assemblage resiliently contacts the first member near the first edge to reduce leakage in the ``plane`` of the cloth-layer assemblage under conditions which include differential thermal growth of the two members. In another seal, such leakage is reduced by having a first weld-bead which permeates the cloth-layer assemblage, is attached to the metal-foil-layer assemblage near the first edge, and unattachedly contacts the first member. 4 figs.

The condensing gas boiler is now state of the art and there is no more room for improvement in performance, technically speaking. The next logical step to improve the overall efficiency is to exploit ambient heat in combination with the primary source of energy, natural gas. That means using natural-gas driven heat pumps and gas-fired heat pumps. Based on this, the Swiss Gas Industry decided to set up a practical test programme enjoying a high priority. The aim of the project 'Gas-fired heat pump practical test' is to assess by field tests the characteristics and performance of the foreign serial heat pumps currently on the market and to prepare and promote the introduction on the market place of this sustainable natural-gas technology.

The natural gas industry and market prospects in Canada are reviewed from a producer's point of view. In the first eight months of 1993, $2.3 billion in new equity was raised for natural gas exploration and production, compared to $900 million in 1991 and $1.2 billion in 1992. The number of wells drilled in the western Canada basin is expected to reach 8,000-9,000 in 1993, up from 5,600 in 1992, and Canadian producers' share of the North American natural gas market will probably reach 20% in 1993, up from 13% in 1986. Potential and proved gas supply in North America is ca 750 trillion ft 3 , of which ca 30% is in Canada. Factors affecting gas producers in Canada are the deregulated nature of the market, low costs for finding gas (finding costs in the western Canada basin are the lowest of any basin in North America), and the coming into balance of gas supply and demand. The former gas surplus has been reduced by expanding markets and by low prices which reduced the incentive to find new reserves. This surplus is largely gone, and prices have started rising although they are still lower than the pre-deregulation prices. Progress is continuing toward an integrated North American gas market in which a number of market hubs allow easy gas trading between producers and consumers. Commodity exchanges for hedging gas prices are beginning operation and electronic trading of gas contracts and pipeline capacity will also become a reality. 4 figs

Gas development plan - Lithuania

1993-10-01

A detailed description of the plan for the development of gas utilization in Lithuania is presented. The plan is subdivided under the headings of gas supply, gas demand, gas transmission and distribution, economy and the organization of the gas sector in the country. The first phase of the project has been undertaken by a Danish firm in cooperation with the Lithuanian firm Lietuvos Dujos. The first aim was to clarify the problems that will arise in connection with this joint venture on developing the use of gas in Lithuania, focusing on existing gas supply and market conditions, the current flow control and metering and economic constraints. The organization of the gas sector in the country as it stands today is described and possible models for its future organization are discussed in addition to a strategy of implementation. Possible development trends are outlined and maximum/minimum demand scenarios are suggested. Subjects and areas related to the gas sector in Lithuania are identified for further investigation in the next phase. It is stated that Lithuania is at present undergoing a fast transformation towards a market economy and that the transfer of foreign currency has been liberalized. Only the pipeline from Minsk to Vilnius is open at present and provides the total supply of natural gas to Lithuania and Kalingrad, controlled by the Russian gas company, Lentransgas, on the basis of a gas purchase agreement regulated on a yearly basis. Other possible supply sources are the Danish part of the North Sea and the Norwegian offshore fields. (AB)

TTA8 - Gas technologies points out the various routes Norway can follow to capitalise on the vast resources of natural gas that will be produced in the years to come by developing a strong technology and competence platform. A broad view is taken for the value creation having as basis the continued gas export from NCS to Europe, but also a strong focus on development of gas resources in other parts of the world. The latter can also be seen as part of international positioning for upstream resources and does also include involvements in projects, and export of technology and products. The TTA has structured the analysis into 3 main areas: Gas transport and processing (pipeline, LNG, other); Gas conversion to fuels, chemicals and materials; CO{sub 2} management. In this report, for each of these areas, scenarios based on a gap analysis are presented. One of the key goals has been to identify pacing and emerging technologies for the next 20 years. Based on this, technologies have been mapped according to importance for future competitiveness and technology ambitions. This also includes primary funding responsibilities (public and/or industry). The road map below reflects the key issues in the proposed strategy. The base level of the figure explains areas that will have to be pursued to maintain Norway's role as a key gas and gas technology provider. The second layer represents near term options and possibilities with a reasonable risk profile that could further enhance the Norwegian position given the resources and drive to further develop this industry. As the top layer we have selected some of our 'dreams', what we may achieve if a progressive approach is followed with a strongly innovation based policy. It is acknowledged by the TTA that Norway cannot be a leading technology player in all aspects of the gas value chain. For some technologies we should be an active player and developer, whilst for other technologies we should become a competent buyer and user. This

A first article illustrates the strong presence of French companies in the shale gas sector, from the exploitation to gas liquefaction. Some examples are evoked: Total (gas fields and petrochemical), CGG (seismic exploration), Vallourec (tube manufacturer), Nexans (cable manufacturer), Imery and Saint-Gobain (ceramic balls used to maintain cracks opened), Saltel (fracturing), SNF Floerger (extraction), GDF Suez (shale gas export). The interest of some foreign actors in the French shale gas is also evoked. A second article reports the activity of Total in Port Arthur, Texas, where it adapted a huge steam cracker to shale gas. This illustrates the renewal of the American petrochemical industry

The GTL - gas to liquids technology was born in Germany, after the 20's with the goal to product liquid fuel from coal to supply the bellicose and domestic demand. The grow of the petroleum industry lead the world to the forgiveness of the GTL technology, except in South Africa. In the last two decades the number of news natural gas reserves and the perspectives of the increase demand from natural gas for the next 20 years change this scenario. Nearly 60% of this reserves are calling stranded or remote, meaning reserves which can't produce with conventional technologies (logistics and economics barriers). So, the oil and gas industry restart to analyze the economics and applicability of the GTL technology. The competitively and applicability of this technology were evaluated and compared to the traditional way of natural gas transport, as well as the solidification of the new environmental rules and the creation of niche to this kind of fuel - the cleans ones - seams the cause of this changes in the oil and gas industries. Which began to adjust to all this news rules and conditions, as show in the sum of investments in R and D area. So, is in this new scenario that the reappear of GTL technology is consider has a technological innovation. (author)

Large scale gas injection test (Lasgit): Results from two gas injection tests

This paper describes the initial results from a large scale gas injection test (Lasgit) performed at the Aespoe Hard Rock Laboratory (Sweden)). Lasgit is a full-scale field-scale experiment based on the Swedish KBS-3V repository concept, examining the processes controlling gas and water flow in compact buffer bentonite. The first 2 years of the test focused on the artificial hydration of the bentonite buffer. This was followed by a programme of hydraulic and gas injection tests which ran from day 843 to 1110. A further period of artificial hydration occurred from day 1110 to 1385, followed by a more complex programme of gas injection testing which remains on going (day 1385+). After 2 years of hydration, hydraulic conductivity and specific storage values in the lower filter array were found to range from 9 x 10 -14 to 1.6 x 10 -13 m/s and 5.5 x 10 -5 to 4.4 x 10 -4 m -1 respectively, with the injection filter FL903 yielding values of 7.5 x 10 -14 m/s and 2.5 x 10 -5 m -1 . A second set of hydraulic measurements were performed over 1 year and a half later yielding similar values, in the range 7.8 x 10 -14 m/s and 1.3 x 10 -13 m/s. The hydraulic conductivity of FL903 had reduced slightly to 5.3 x 10 -14 m/s while specific storage had increased to 4.0 x 10 -5 m -1 . Both datasets agree with laboratory values performed on small-scale saturated samples. Two sets of gas injection tests were performed over a 3 year period. During the course of testing, gas entry pressure was found to increase from around 650 kPa to approximately 1.3 MPa, indicative of the maturation of the clay. The sequential reduction in volumetric flow rate and lack of correlation between the rate of gas inflow and the gas pressure gradient observed during constant pressure steps prior to major gas entry, is suggestive of a reduction in gas permeability of the buffer and indicates only limited quantities of gas can be injected into the clay without interacting with the continuum stress field.

Natural gas is an important component in many of the technologies aimed at reducing greenhouse gas emissions. In order to understand the role that natural gas can play, it is important to know how much may be present, where it is, when can it be accessed and at what cost. The Canadian Gas Potential Committee has completed its second report 'Natural Gas Potential in Canada - 2001' (CGPC, 2001). This comprehensive study of exploration plays in Canada addresses the two issues of 'how much may be present' and 'where is it'. The Report deals with both conventional gas and non-conventional gas. One hundred and seven Established Conventional Exploration Plays, where discoveries of gas exist, have been assessed in all of the sedimentary basins in Canada. In addition, where sufficient information was available, twelve Conceptual Exploration Plays, where no discoveries have been made, were assessed. Sixty-five other Conceptual Plays were described and qualitatively ranked. An experienced volunteer team of exploration professionals conducted assessments of undiscovered gas potential over a four-year period. The team used technical judgment, statistical techniques and a unique peer review process to make a comprehensive assessment of undiscovered gas potential and estimates of the size of individual undiscovered gas accumulations. The Committee assessed all gas in place in individual exploration plays. For Established Plays, estimates of Undiscovered Nominal Marketable Gas are based on the percentage of the gas in place that is marketable gas in the discovered pools in a play. Not all of the Nominal Marketable Gas will be available. Some underlies areas where exploration is not possible, such as parks, cities and other closed areas. Some will be held in gas pools that are too small to be economic and some of the pools will never be found. In some areas no production infrastructure will be available. Detailed studies of individual exploration plays and basins will be required
