  1. Ricardo Dyrgalla (1910-1970), pioneer of rocket development in Argentina

    de León, Pablo

    2009-12-01

    One of the most important developers of liquid propellant rocket engines in Argentina was Polish-born Ricardo Dyrgalla. Dyrgalla immigrated to Argentina from the United Kingdom in 1946, where he had been studying German weapons development at the end of the Second World War. A trained pilot and aeronautical engineer, he understood the intricacies of rocket propulsion and was eager to find practical applications to his recently gained knowledge. Dyrgalla arrived in Argentina during Juan Perón's first presidency, a time when technicians from all over Europe were being recruited to work in various projects for the recently created Argentine Air Force. Shortly after immigrating, Dyrgalla proposed to develop an advanced air-launched weapon, the Tábano, based on a rocket engine of his design, the AN-1. After a successful development program, the Tábano was tested between 1949 and 1951; however, the project was canceled by the government shortly after. Today, the AN-1 rocket engine is recognized as the first liquid propellant rocket to be developed in South America. Besides the AN-1, Dyrgalla also developed several other rockets systems in Argentina, including the PROSON, a solid-propellant rocket launcher developed by the Argentine Institute of Science and Technology for the Armed Forces (CITEFA). In the late 1960s, Dyrgalla and his family relocated to Brazil due mostly to the lack of continuation of rocket development in Argentina. There, he worked for the Institute of Aerospace Technology (ITA) until his untimely death in 1970. Ricardo Dyrgalla deserves to be recognized among the world's rocket pioneers and his contribution to the science and engineering of rocketry deserves a special place in the history of South America's rocketry and space flight advocacy programs.

  3. Ricardo, o tempo e o valor

    Rogério Arthmar

    2014-03-01

    Full Text Available O artigo revisa a evolução da teoria ricardiana do valor em sua conexão com o elemento tempo. Inicialmente, procede-se breve inspeção da primeira proposta de Ricardo para a lei geral das trocas. Contempla-se, a seguir, uma ilustração numérica da fórmula original dos preços competitivos, esclarecendo-se como o fator tempo surgiu nas discussões sobre a teoria desenvolvida nos Principles. Examina-se ainda a versão simplificada da regra do valor introduzida na terceira edição do livro, assim como a proposição ricardiana fundamental de que as variações nos lucros teriam impacto mínimo nos preços. Mostra-se, na última seção, que a generalização do exemplo concebido por Ricardo, incluindo processos produtivos com múltiplos períodos, não sustenta tal asserção.

    Full Text Available In this article the writer and Argentine Ricardo Piglia profesor stands at the center of the academic debate on literary education based on the idea that his poetic reading hypothesis provides a framework capable to build viable research on the formation of the reading and literary competence. His ideas about circuits of knowledge production about reading, types of readers, the debate on the canon narrative and intertextuality, are considered fundamental to the discussion and to contribute to the discussion on how we should teach literature in a context governed by new technologies and the new reading.

  6. Hydrotherapy and medical entrepreneurship: the "water spell" of Ricardo Jorge.

    Pinto Costa, Rui Manuel

    Between 1886 and 1893, the doctor and hygienist Ricardo Jorge was linked to a commercial and medical project on the waters of Gerês. Known for many centuries and used for therapeutic purposes, they were administered on an empirical basis. When new chemical analyses were first published, the empirical properties of these waters took on a new role in hydrotherapy based on their now proven mineral and medicinal qualities. The article discusses in detail Ricardo Jorge's business venture, framing it in the context of the economic collection and treatment potential of mineral waters and the revival of the phenomenon of hydrotherapy, legitimized by new developments in the chemical analysis of waters. The commercial failure to exploit the water resources highlights the difficulties of this project and the complexity of the professional practice of hydrological medicine, although it resulted in a strengthening of Ricardo's authority and prestige in the field of hydrotherapy.

  7. Experimental farming and Ricardo's political arithmetic of distribution

    Mary S. Morgan

    2005-01-01

    The development of David Ricardo’s economic theory of distribution - the laws that determine the share of output between the economic classes - depended on specific connections at several levels between two practical sciences of the early 19th century, namely experimental agriculture and political economy. This paper shows how Ricardo, one of the foremost British economists of his day, combined his empirical knowledge of farming and agricultural experiments to develop both the content and met...

  9. Straight talk with... Ricardo Dolmetsch. Interview by Elie Dolgin.

    Dolmetsch, Ricardo

    2013-11-01

    Neuroscience, in recent years, has started to look like a graveyard for drug development, with many large pharmaceutical companies either eliminating their brain disorder programs or cutting back heavily on such research. Novartis seemed to have made exactly this kind of drastic change two years ago when the company announced plans to shutter its neuroscience operations at its global headquarters in Basel, Switzerland. But the company made it known then that its intention was to ultimately set up a new neuroscience division at the company's US base in Cambridge, Massachusetts. The US site was initially picked to take advantage of the local academic strength in the field of psychiatric genetics. Now, it seems that Novartis is also looking to add stem cell technologies to the mix with the appointment in August of Ricardo Dolmetsch as the company's global head of neurosciences-the first new hire for the company's reincarnated division. As a professor at California's Stanford University School of Medicine for the past ten years, Dolmetsch made his name using induced pluripotent stem (iPS) cells to study a rare form of autism known as Timothy syndrome. Elie Dolgin met with Dolmetsch at the Novartis Institutes for BioMedical Research in the Technology Square area of Cambridge to discuss how he plans to succeed where so many others have failed.

    2012-01-01

    This paper studies an equilibrium model of social and cognitive skills interactions in school, work and marriage. The model uses a common team production function in each sector which integrates the complementarity concerns of Becker with the task assigment and comparative advantage concerns of Ricardo. The theory delivers full task specialization in the labor and education markets, incomplete task specialization in marriage. It rationalizes many to one matching, a common feature in labor mar...

  12. Theory of Money of David Ricardo: Quantity Theory and Theory of Value

    Susumu Takenaga

    2003-01-01

    Full Text Available En lo que es necesario enfatizar, al caracterizar la teoría cuantitativa de David Ricardo, es en que ésta es una teoría de determinación del valor del dinero en una situación particular en la cual se impide que el dinero, sin importar cual sea su forma, entre y salga libremente de la circulación. Para Ricardo, la regulación del valor del dinero por su cantidad es un caso particular en el cual el ajuste del precio de mercado al precio natural requiere un largo periodo de tiempo. La determinación cuantitativa es completamente inadmisible, pero solo cuando el período de observación es más corto que el de ajuste. En todo caso, la determinación del valor del dinero rara vez es vinculada a su teoría del valor de las mercancías. Contrario a la interpretación aceptada comúnmente, Ricardo no aplicó a la determinación del valor del dinero una teoría del valor distinta de aquélla aplicada a las mercancías en general.

  13. EN LA TEORÍA ECONÓMICA DE DAVID RICARDO

    FRANCISCO CORREA RESTREPO

    2015-01-01

    Full Text Available Este artículo tiene como objetivo central analizar el papel del recurso tierra en la teoría económica de David Ricardo como primer acercamiento al análisis económico de los recursos naturales. Esto se realiza mediante una revisión bibliográfica analítica de la obra de Ricardo y de otros autores en torno a la misma. En este sentido, se examina el concepto de renta de la tierra, así como los planteamientos en torno a la llamada ley de los rendimientos decrecientes. Asimismo, se establecen algunas reflexiones críticas con relación al enfoque de la renta de la tierra. Un resultado importante del trabajo es que en el análisis de la renta de Ricardo está ausente el concepto de costo de oportunidad, lo cual implica una reconsideración del concepto de renta para abordar el análisis económico de recursos naturales.

  15. La discretio en Beniamin minor de Ricardo de San Víctor

    Carlos Hallet

    2006-01-01

    Full Text Available La estructura del alma y la antropología han sido temas abundantemente desarrollados por los autores cristianos medievales a partir de la expresión bíblica "imagen y semejanza". En ese contexto conceptual, el Beniamin minor de Ricardo de San Víctor muestra cómo ratio y affectio necesitan la discretio para equilibrar todas las virtudes y poder acceder a la contemplación. Ricardo, que ve en cada hijo de Jacob, un símbolo de las virtudes, atribuye la discretio a José, hijo de Raquel, quien a su vez representa la razón. El artículo recuerda cómo, ya a partir del final del siglo XII, la discretio quedará absorta en la noción de prudencia. Ricardo siendo su último e importante exponenteThe soul structure and the anthropology are topics that the christian authors of the Middle Age abundantly explained starting from the biblical expression imago et similitudo. In that conceptual context, Beniamin minor of Richard of Saint Victor demonstrates that ratio and affectio need discretio in order to equilibrate all the virtues and to be able to accede to the contemplation. Richard, who sees in every son of Jacob a symbol of the virtues, attributes discretio to Joseph, which is the son of Rachel, the symbol of reason. The article shows that, from the end of the XIIth century, discretio will be absorbed in the virtue of prudentia. Richard is his last and more important exponent

    2011-04-01

    Full Text Available La Nena” is one of the short-stories generated by the narrative machine of Ricardo Piglia’s novel La ciudad ausente (1992, and it proves to be the key for understanding the capacity of the storytelling process to function  as a tool for  the reconstruction of the narrating subject and its  experiences. Besides that, it hides the story of Laura, “la nena” that is mentioned in the title, a story that parallels  the story of the machine that created it, allowing, in part, to understand its  points of origin and its programming. “La nena” is also a tale generated according to the central theme of loss which sustains not only n the story history of the machine’s origin, but also that of the novel and of other short-stories within.

    Full Text Available Analisa-se, no artigo, as diferentes formas com que a ironia se efetiva em um texto literário. Parte-se do pressuposto de que a ironia configura, ao mesmo tempo, uma figura de linguagem, como uma sentença que anula a si mesma na medida em que orienta o leitor a rejeitar seu significado literal; e uma visão de mundo, na medida em que implica uma postura de negação de uma realidade. À luz dos preceitos de D.C. Muecke e Søren Kierkegaard, busca-se identificar as dimensões irônicas da peça Ricardo III, de William Shakespeare, e refletir acerca delas.

    Carlos Hernán Sosa

    2010-11-01

    Full Text Available This work intends to analyze the novel Lata peinada [2008] by Ricardo Zelarayán, which shows a recovery of the uses of narrative experimentation in the tradition of Macedonio Fernández' antinovel and of the writing mode with variations as practiced by Leónidas Lamborghini. These filiations, eminently rooted in the literary history of the Río de la Plata, are articulated with linguistic uses that try to subtly imitate oral forms typical of Northwest Argentina, where the stories narrated take place. In this sense, Zelarayán's writing allows us to analyze the curious choice of an author who struggled for many years to place himself in the literary field of the city of Buenos Aires and who put forward a style interweaving strong metropolitan traditions [Macedonio, Cortázar, Lamborghini] with outstanding -though less renowned- authorial figures from the provinces [Manuel J.

Como suporte teóricometodológico, utilizamos as ideias sobre o absurdo de Camus. Durante a análise, percebemos que o espaço em que se desenvolvem as ações narradas em Caieira representa uma relação de dominação, em que os personagens são reduzidas a fantasmas ou objetos, presas num mundo de cal, árido de humanidade. Mesmo quando o personagem principal tenta reverter o quadro, acaba se transformando num reverso da mesma moeda, repetindo o modelo de dominação contra o qual se insurge, reeditando um ciclo de poder e dominação. Palavras-chave: Literatura brasileira; análise literária; absurdo; espaço.Abstract: Our aim in this paper is to analyze the space of the absurd at the novel Caieira, by Ricardo Guilherme Dicke, writer from Mato Grosso. As a theoretical-methodological support, we use the ideas of on the absurd presented by Camus. During the analysis, we find that the space in which the actions narrated in Caieira develop represents a relationship of domination, in which the characters are reduced to objects or ghosts, trapped in a world of lime, arid of humanity. Even when the main character tries to reverse the situation, eventually becoming a reverse of the same coin, repeating the pattern of domination against which it protests, reissuing a cycle of power and domination.

  8. Ensino da Bioética Convergente de ricardo maliandi nos Cursos de medicina

    Nalita Maria Hall Brum de Barros Mugayar

    Full Text Available RESUMO Este artigo sublinha a patente deficiência dos currículos de Medicina em relação às Ciências Humanas e defende que o estudo da Bioética — disciplina que procura integrar as Ciências Humanas às Ciências Biológicas — poderá ajudar a preencher essa nociva lacuna. Apresentamos a Bioética Convergente de Ricardo Maliandi e Oscar Thüer como um valioso arcabouço teórico capaz de auxiliar o médico a protagonizar a resolução dos conflitos éticos inerentes à sua prática profissional, sem incorrer em unilateralidade. Comparamos sua fundamentação teórica com a conhecida proposta, também principialista, de Beauchamp e Childress, apontando as vantagens daquela em relação a esta. Exemplificamos sua aplicabilidade com a análise de potenciais conflitos éticos inferidos de informações obtidas em prontuário de uma paciente internada no Centro de Terapia Intensiva do Hospital Universitário Antônio Pedro. Para a realização dessa análise, buscamos, na literatura médica, dados probabilísticos em relação ã doença em questão (neoplasia de esôfago com fístula traqueoesofageana complicada por choque séptico pulmonar, ressaltando que esses dados podem ajudar na melhor compreensão do prognóstico, sem que por isso possam ser utilizados como respaldo da equipe médica para decisões unilaterais de limitação terapêutica. A literatura médica também nos brindou com propostas de condução de casos difíceis do ponto de vista ético, como o da paciente em tela. Escolhemos uma delas (Azoulayet al.12, reconhecendo e demonstrando sua compatibilidade com a Bioética Convergente de Maliandi e Thüer. Trata-se de um ensaio teórico sobre limitação terapêutica, no qual procuramos unir a fundamentação da literatura à aplicabilidade em um caso real de paciente crítica. Acreditamos que este artigo poderá ser um ponto de partida para a difusão da Ética Convergente — trabalho de toda a vida do filósofo Ricardo

    Exclusive writings on the contribution of Ibn Khaldun to economics in the English language have not been many, the references to his work also remain scanty and far between.

    Full Text Available Este artículo analiza la magnitud del crecimiento en el sector agrícola antes de la industrialización en Korea. Presenta un análisis que es contrario del punto de vista general sobre la naturaleza del crecimiento económico en Korea, cual es el de que éste fue muy poco en el sector agrícola antes del despegue industrial. Los datos sugieren más bien, que se realizaron grandes inversiones durante la colonización japonesa. Estas inversiones tuvieron altos rendimientos no sólo en términos de producción de arroz sino también en términos de construcción de capacidad institucional y creación de infraestructura. El caso koreano no es una anomalía sino un ejemplo algo singular e interesante de desarrollo agrícola que antecede a una rápida expansión industrial.

  11. De lo inmaterial literario al monumento arquitectónico: la casa museo de Ricardo Rojas / From the literary immateriality to the architectural monument: the House Museum of Ricardo Rojas

    Amanda Salvioni

    2015-02-01

    The House Museum of Ricardo Rojas, built in 1927 by the architect Angel Guido in Buenos Aires, is an ideal starting point for a reflection on the social uses of cultural heritage in Twentieth Century Argentina. The House reflects an aesthetic program that intended to reinvent the national tradition as a fusion between indigenous and Hispanic elements. Nonetheless, the national tradition codified by Rojas and Guido was the result of an arbitrary selection of heterogeneous elements that excluded immigrants and did not guarantee access to cultural heritage of all sectors of society. The project of the House was directly related to the emergence of cultural and politic nationalism that took place in Argentina from the Centenary of Independence in 1910 to the beginning of Second World War. This essay focuses on the contradictions of monumentalization of intangible cultural heritage in a multicultural society.

    Joaquim Miguel Couto

    2011-08-01

    Full Text Available A questão do desemprego tecnológico preocupou a mente de dois dos maiores pensadores da ciência econômica: David Ricardo e Karl Marx. Ambos acreditaram que a introdução de novas máquinas poderia causar uma situação de desemprego crônico durante certo período de tempo. No entanto, esta era apenas uma possibilidade, que já havia ocorrido no capitalismo industrial inglês, mas que poderia ser evitada caso novos investimentos absorvessem a mão de obra dispensada pela introdução de nova maquinaria. O Brasil, por sua vez, passou, ao longo da década de 1990, por um período de reestruturação de seu parque industrial que, mediante a metodologia utilizada em nosso estudo, resultou na conclusão da existência do fenômeno do desemprego tecnológico durante boa parte da referida década.The issue of technological unemployment was a cause for concern for two of the greatest thinkers in the field of economic science: David Ricardo and Karl Marx. Both believed that the introduction of new machines could bring about chronic unemployment for a certain period of time. However, this was only a possibility that had already taken place within English industrial capitalism, but that could be avoid if new investments absorbed the workforce laid off by the introduction of new machinery. In the case of Brazil, the country underwent a restructuring period of its industrial base during the 1990s, which according to the methodology employed in our study, verified the existence of the technological unemployment phenomenon during much of the aforementioned decade.

    Full Text Available Este estudio propone una lectura de Respiración artificial (1980, de Ricardo Piglia, desde la perspectiva del subgénero de la novela de artista, de acuerdo con la definición de Herbert Marcuse, que ha sido validada para las novelas de artista hispanoamericanas de finales del siglo XIX, en las que se centran la mayoría de los estudios críticos. La representación del escritor en Respiración artificial se compara con su representación en la narrativa de fin de siglo con un doble objetivo: poner de manifiesto el hecho de que Respiración artificial es una novela de artista propiamente dicha y asimismo mostrar la reformulación del subgénero llevada a cabo por Piglia a través de su amalgama con el policial. Palabras clave: novela hispanoamericana, novela de artista, policial latinoamericano, Ricardo Piglia, Respiración artificial.   This paper proposes a reading of Artificial respiration (1980 by Ricardo Piglia as an artist novel, according to Herbert Marcuse’s definition, validated for Latin American artist novels written at the end of the nineteenth century. The most influential critical studies have focused on that period. In this paper, the representation of the writer in Artificial respiration is compared with its corresponding representation at the end of the nineteenth century. This comparison allows us to highlight, on the one hand, the survival of the artist’s novel as an answer to the purpose of the literature after the end of the utopias. And on the other hand, the literary change carried out by Piglia: his reformulation of the character of the writer and also of the artist novel by employing narrative methods coming from the detective subgenre. Keywords: Latin American novel, artist’s novel, Latin American detective fiction, Ricardo Piglia, Artificial respiration.

    Full Text Available El presente artículo aborda el trabajo profesional del bibliotecario Ricardo Gietz, entre los años del Estado Benefactor desarrollado por el peronismo hasta el desmantelamiento del mismo por el neoliberalismo en la década de 1990. El interés en la figura de Gietz, se debe a que fue el único latinoamericano que tuvo a su cargo la presidencia de la FID, fue director del CAICYT y del Servicio Iberoamericano de Información sobre la Traducción de la UNESCO en la Argentina, entre otros cargos que ocupó en organismos nacionales e internacionales. Ha sido uno de los documentalistas más importantes que tuvo el país, no obstante, es desconocido para las nuevas generaciones de trabajadores de la información. Junto a su padre, que también había sido bibliotecario, tuvieron un papel clave en la implementación de políticas documentales y bibliotecológicas que, en algunos casos, siguen dando frutos dentro y fuera del CONICET = This article deals with the professional work of the librarian Richard Gietz, between the Welfare State developed by Peronism to the dismantling of the same by neoliberalism in the 1990s. The interest in the figure of Gietz is in that he was the only Latin American who was in charge of the presidency of FID, was the director of CAICYT, and of Latin American Service on Translation Information of UNESCO in Argentina, among other charges in national and international organizations. He was one of the most important documentalists in the country, however, he is unknown to the new generations of information workers.

  18. Ricardo Piglia lector de Walter Benjamin: compromiso político y vanguardia artística en los 70 argentinos.

    Luis Ignacio García García

    2014-03-01

    This paper analyzes the reception of Walter Benjamin by the young Ricardo Piglia. Walter Benjamin, together with Bertolt Brecht, was very important for Piglia’s self-comprehension in the context of the agitated aesthetical-political debates of the ’60s and ’70s. Piglia makes use of the Brechtian Benjamin to articulate aesthetics and politics in a way that singles out his critical work in those years. He builds, from the parameters of a production aesthetic, a position that goes beyond not only the idealistic aesthetics but also the principles of the socialist realism, putting aside the opposition between aesthetic experimentation and politicization of art.

    The scope of this paper is to analyze the provision of biomedical care in Angola during the activities of the Companhia de Diamantes de Angola. A comparative analysis of public health policies and practices of various colonial actors, such as the health services of the Company, its state counterpart and other colonial companies, will reveal differences in investment in health, namely in health facilities, personnel and treatment. This survey as well as the living conditions highlight the idiosyncratic and central nature of the health services of the Company in terms of morbidity and mortality in Angola, and the importance of these representations for a caregiving empire.

    Full Text Available This article critically resumes Ricardo's principle of comparative advantages pointing out internal coherence problems that have been neglected by the specialized literature. First, long-lasting disequilibria observed in the balance of trade seem incompatible with the idea that these disequilibria are caused by technical advances that change relative prices. Second, comparative advantages do not seem to work in an economy with a universally accepted commodity-money. Finally, the contradiction between the gold standard mechanisms, ruled by Smith's "Law of Reflux", and the quantitative theory of money, which is a necessary condition for the "second way" of the theory of comparative advantages.

    Anonadados por lo impetuoso de su separa-ción definitivanos reunimos aquí hoy bajo el cielo invernal de una Bogotá doliente para despedir los restos mortales de un paradigma de académicos, de señores y amigos como fue Ricardo Rueda González. Quizás así lo hubiera querido él, epítome de la elegancia y el ingenio bogotanos, para irse de esta tierra ajustando su corbata Tremlet, su chaqueta de Tweed y su bufanda de Cachemira como para salir airoso de este club del mundo moderno, que lo tenía ya aburrido por lo abigarrado, por lo vulgar y por lo anónimo; y llegar a donde el Padre Eterno sin presumir, confrmando que “la elegancia es el arte de pasar desapercibido”, como lo hubiera dicho Oscar Wilde, uno de sus autores preferidos.

    Porque tal es, señores académicos, queridos familiares y amigos, la imagen superficial que nos deja Ricardo. Digo superfical, porque en el fondo se agitaba el más profundo de los humanistas y el más compasivo y atento de los médicos, preocupado a toda hora por ayudar a sus abnegadas pacientes a concebir y a dar a luz lo mejor de sus entrañas, así como él mismo se preocupaba siempre por dar a luz lo mejor y más vivaz de su gracia y de su intelecto.

    Full Text Available [es] Durante gran parte de su itinerario plástico, el artista rosarino Ricardo Warecki elaboró imágenes gráficas inspiradas en los repertorios iconográficos y en las convenciones estéticas de los movimientos modernos. Las nuevas formas de figuración, el expresionismo y el surrealismo fueron reinterpretados en una clave peculiar a partir de ilustraciones y grabados. En ellos prevalece desde una mirada sobre el sentimiento melancólico hasta paisajes oníricos, donde aparecen el erotismo y la violencia de los márgenes urbanos o la aspereza de la propia naturaleza. Estas imágenes, publicadas en periódicos y revistas culturales de Rosario desde finales de los años treinta hasta los primeros cuarenta, eran acompañadas por relatos literarios con un estilo narrativo cercano a lo fantástico. Si bien dicho vínculo operó como refuerzo de sentidos, Warecki se permitió ciertas licencias que le dejaron explorar significados diversos, excediendo las propias narraciones literarias. En un continuo devenir entre la representación de atmósferas de sosiego y escenarios caóticos, sus ilustraciones exhibieron una mirada cargada de emociones contrapuestas. Una ambigüedad que constituiría un rasgo distintivo tanto de su obra gráfica como de su personalidad. [en] During a large part of their itinerary plastic, the artist of Rosario, Ricardo Warecki, produced graphic images inspired by the iconographic repertoire and the aesthetic forms of the modern movements.

    孙尚诚

    2012-01-01

    Both David Ricardo and Bernard Mandeville made great contribution to the development of modern economic thought. The former is a representative of utilitarianism, and the latter is a representative of egotism. Although they all emphasized the role of personal interests acting on social interests, there are fundamental differences between them. When the principle of general happiness, which was put forward by the David Ricardo, is regarded as an example, compared with " private vices, public benefits" which was put forward by Bernard Mandeville, we can find the fundamental differences between the two schools obviously. And the most important difference is that egoism has deliberately despised the social morality, but utilitarianism has never given up the pursuit of justice.%大卫·李嘉图和伯纳德·曼德维尔都对经济思想的形成和发展作出了很大贡献。前者代表的是功利主义,后者代表的则是利己主义。尽管他们都强调个人利益对社会利益的作用,但二者之间又有根本的分歧。以李嘉图的一般幸福原则为例,并与伯纳德·曼德维尔的“私恶即公利”进行对比。就可以明显看出两个学派的根本歧异。其中最重要的歧异就在于,利己主义显然有意地藐视了社会的道德,而功利主义却从来没有放弃过对于公正的追求。

    Pinto, H. S.; Assad, E. D.; Pavao, E.; Luna, R.

    2012-12-01

    According to the Brazilian Government (CONAB, July 2012) the actual area of grain production in the country is close to 50.8 million ha and the perspective of production is 162.6 million of tons. Maize and Soybean are responsible for more than 83% of the total harvest. The area available for agriculture in Brazil is 282.2 million ha or close to 33% of the total land of the country. From 1991 until 2010 the agricultural technology was responsible for an increase of production close to 154% while the planted area raised only 25%. Considering this rate of production in the last 20 years the Ministry of Agriculture made an extrapolation for 2020, when the country can produce close to 176 million of grains being 65 million tons of maize, 86 million tons of soybean and 70 million bags of coffee. In this case, it was not considered any variation in the climate conditions. In 2002, in partnership with the British Embassy in Brazil, Unicamp and Embrapa published the study "Global Warming and the New Geography of Agricultural Production in Brazil" (Pinto and Assad, 2002) based on a Regional Climate Model PRECIS from Hadley Centre, where the grain production was estimated to decrease due to temperature rise. Without considering any mitigation or adaptation action, in the worst scenario (A2-IPCC) the principal crops to be affected will be coffee with 6.7% estimated production decrease until 2020, soybean 22% and corn 12%. On the other hand, sugar cane, as a C4 plant, will have an increase of production in the order of 170%. As suggested by the Word Bank, a new project was developed for a more detailed analysis of the influence of the global warming in the Brazilian agriculture, affecting temperature and water deficit in the years 2020 and 2030. It was considered initially 23 Global Climatic Models (GCM) defined by IPCC, that were separated in blocks of similar comportment using cluster multivariate analysis. Other 3 Regional Climatic Models (RCM) were also used to give more detailed information of the future scenarios: PRECIS, BRAMS and ETA. The 4 GCMs that showed more similarity among themselves and the 3 RCM were used as simulation models with similar behavior for establishing the new scenarios for 2020 and 2030. The better and the worst forecast of the curves were used as simulation points for the future agriculture scenarios. In Brazil, most part of the agricultural plantation as well as the insurance are financed by the Ministry of Agriculture that has a basic directive of following the Public Policy Program of Climatic Risk Zoning for authorizing what, when and where to plant according to climate predominance. Based in this program and in the new climatic scenarios provided by the 7 models, a new geography for Brazilian agriculture was suggested for the years 2020 and for 2030 showing the same pessimistic tendency of decrease in production close to 24% for soybean and 19% for maize summer season as compared to 2012. The results obtained with this study were used as input for the economics complimentary analysis of Brazilian possible modification of the agribusiness until the years 2020 and 2030.

  6. 150th anniversary of veterinary education and the veterinary profession in North America: part 2, 1940-1970.

    Smith, Donald F

    2011-01-01

    This article is the second in a series of four to be published in the Journal of Veterinary Medical Education (JVME). These articles are abridged versions of six lectures that make up an elective course on the history of the veterinary profession in North America offered at Cornell University's College of Veterinary Medicine to students in all four years of the program. The course is built in part on a series of biographies and interviews captured in a collection at http://www.vet.cornell.edu/legacy, and complemented by a growing collection of historical and public policy blogs at http://www.veterinarylegacy.blogsite.com. This article describes the development of the veterinary profession from 1940 to 1970, with particular emphasis on World War II, the Land Grant colleges established in the mid- and late 1940s, women in veterinary medicine (1910-1970), and African-Americans (ca. 1890-1945). Though the article is somewhat Cornell-centric because the lectures were presented to Cornell students at their home institution, many events are representative of the broader American experience.

    This paper was presented at the Seminars of the Department of Foundations of Economic Analysis I, University of the Basque Country in September 2004. This paper has two parts. In the first I critically analyze Smith’s refutation of the labor theory of value in book I, chapter 6 of his “Wealth of Nations”. My thesis is that Smith’s refutation is unsound and that Ricardo and Marx rightly saw why. In the second part I discuss Blaug’s critique of the Ricardo-Marx refutation of Smith. According...

    2003-01-01

    This paper examines the long-run determinants of immigration to Germany using a modified version of the Ricardo model. After a brief overview of labour flows to Germany and the related empirical literature, a Ricardian model of migration is estimated using static panel data methods. The results show that variables representing factor abundance appear to have no effect whatsoever on labour flows to Germany in a period of rising unemployment (1974–1999), while variables representing income or p...

  15. THE EVALUATION OF THE CHARACTER RICCARDO FONTANA IN THE MOVIE AMEN. IN TERMS OF KOHLBERG’S MORAL DEVELOPMENT STAGES

    Fatma Sariaslan

    2016-10-01

    Full Text Available This study aims to analyze Riccardo Fontana, one of the main characters of the movie “Amen.” directed by Constantin Costa-Gavras in 2002, in terms of Kohlberg’s moral development stages. At the center of the movie lies the efforts of the SS officer Kurt Gerstein, posted in the army, and Ricardo Fontana, in the service of the church, to announce the holocaust policy of Hitler to the world. The movie gives a conspicuous voice to how the two main characters inexhaustibly struggled to resist the holocaust policy and what they did to announce this fact to the world and also how they strove to prioritize their faith of ethics over the drive to self protection. An SS officer, Kurt Gerstein constantly condemns the crimes, warns the allies, the Pope and the church of Germany but at the same time provides the Zyklon B gas used in camps. Ricardo Fontana, a Jesuit in the service of the church, is a reverend who aims to break the silence in the Vatican, which has kept its silence against the entire holocaust. And here in this article will the reader find an evaluation of the character named Ricardo Fontana in terms of Kohlberg’s moral development stages.

  16. METHODS TO MEASURE, PREDICT AND RELATE FRICTION, WEAR AND FUEL ECONOMY

    High-fidelity measurements of the coefficient of friction and the parasitic friction power of the power cylinder components have been made for the Isuzu 5.2L 4H on-highway engine. In particular, measurements of the asperity friction coefficient were made with test coupons using Argonne National Lab’s (ANL) reciprocating test rig for the ring-on-liner and skirt-on-liner component pairs. These measurements correlated well with independent measurements made by Electro-Mechanical Associates (EMA). In addition, surface roughness measurements of the Isuzu components were made using white light interferometer (WLI). The asperity friction and surface characterization are key inputs to advanced CAE simulation tools such as RINGPAK and PISDYN which are used to predict the friction power and wear rates of power cylinder components. Finally, motored friction tests were successfully performed to quantify the friction mean effective pressure (FMEP) of the power cylinder components for various oils (High viscosity 15W40, low viscosity 5W20 with friction modifier (FM) and specially blended oil containing consisting of PAO/ZDDP/MoDTC) at 25, 50, and 110 °C. Ricardo's objective is to use this data along with advanced CAE methods to develop empirical characterizations of friction and wear mechanisms in internal combustion engines such that the impact of such mechanisms of engine fuel consumption and/or vehicle fuel economy can be estimated. The value of such predictive schemes is that if one knows how a particular friction reduction technology changes oil viscosity and/or the friction coefficient then the fuel consumption or fuel economy impacts can be estimated without the excessive cost of motored or fired engine tests by utilizing cost effective lab scale tests and in combination with advanced analytical methods. One accomplishment made during this work was the development and validation of a novel technique for quantifying wear using data from WLI through the use of

    2014-01-01

    The terminology employed by Smith to refer to value and measure of value is used in his time with imprecision, which has led to different interpretations about his position on these issues. It is no coincidence that Smith is considered the father of the labour theory of value developed by David Ricardo and Karl Marx and simultaneously of the cost-of-production theory of value developed by John Stuart Mill and Alfred Marshall. This paper reviews the concepts developed by Smith to formulate his...

  3. El trabajo en Smith: valor o medida del valor?

    Adolfo Rodríguez Herrera

    2016-12-01

    Este artículo revisa los conceptos desarrollados por Smith para formular su teoría del valor (valor, precio real y valor de  cambio. Nuestra interpretación de sus textos sobre el valor no coincide con la que tradicionalmente se ha hecho. De acuerdo con nuestra interpretación, no sería correcta la crítica de Ricardo y Marx a la posición de Smith sobre el papel del trabajo como medida de valor. Para estos autores, Smith no es consistente al proponer que el valor de una mercancía es definido o medido como la cantidad de trabajo necesaria para producirla y simultáneamente como la cantidad de trabajo que puede ser comprada por esta mercancía. Tratamos de demostrar que para Smith el trabajo tiene un doble papel –como fuente y como medida del valor–, y que a ello se debe la confusión generada por su uso de algunos términos: Smith propone el trabajo como una medida de valor porque lo concibe como una fuente de valor. Con esta interpretación queda claro, paradójicamente, que la teoría del valor trabajo de Smith corresponde sustancialmente con la que más tarde desarrollarán Ricardo y Marx.

  5. Interplay simulation/testing in the optimisation of gearshift quality for manual transmissions; Zusammenspiel Simulation/Erprobung bezueglich optimierte Schaltqualitaet von Handschaltgetriebe

    Leist, S.; Donin, R. [Ricardo Deutschland GmbH, Schwaebisch Gmuend (Germany); Kelly, D. [Ricardo DTS, Leamington Spa (United Kingdom)

    2005-07-01

    Passenger comfort is an aspect of the development of modern passenger cars that cannot be overlooked. Achieving a high degree of shift comfort, i.e. a combination of shift feeling and low shift forces, is a great challenge, since the mechanical processes taking place are highly non-linear and arbitrary. A purely test-based programme of shift quality development is cost- and time-intensive. Such a programme runs the risk of not delivering the necessary results on time. Therefore it is necessary to develop a methodology that facilitates a complementary interplay between simulation and testing, and in which the vehicle is considered as a complete system. Sub-systems such as shift lever, inner and outer shift mechanism, transmission, clutch and engine must be considered very carefully with regard to the system requirements, which are often conflicting. Over the last 15 years, Ricardo has developed a tool with which shift quality can be objectively assessed-''GSQA - Gear Shift Quality Assessment''. Today, with the help of its detailed dynamic simulation models, Ricardo is in a position to solve complex shift quality problems in the concept phase as well as in series production. (orig.)

Just to have an idea of the dimension achieved, data obtained from http://www.a9.com (an Amazon.com site or with the traditional search engine Google, prove that the first reply when you request information about long QT Syndrome is the access site of the Symposium. We believe that the response to this question may be summarized in one word: REALIZATION. The best definition for success is realization. The huge motivation in each one of us made the difference. We worked with a cohesive group, like a team, aware of the unparalleled and great opportunity Prof. Arthur Moss had initially assigned to Sergio Dubner and Edgardo Schapachnik, an invitation that the latter extended to Andrés Ricardo Pérez Riera.

    Full Text Available First approach to the identification of mitigation/intensification markers in translating journalistic articles from bilingual publication in English and its translation into Spanish. There are three articles from Newsweek Magazine, a useful tool to use with translation students. The objective is the Annotated Translation of finished articles and book chapters that, after a pre-screening analysis, foster the translation of the Spanish version from written English texts. The first journalistic article with a historical theme is: The Return of Ruthless Richard – El Regreso del despiadado Ricardo (Ricardo III, used to detect the mitigation/intensification markers in both versions. Steps: 1. Sentence by sentence analysis in English, to find mitigation characteristics. 2. Review selected sentences in English with the Spanish counterpart. 3. Comparison and contrast of both versions. 4. Discuss similarities/differences to notice if the transfer of markers signals mitigation/intensification in both versions. 5. Discuss findings and write comments of translation aspects whose changes are discussed: annotated translation. Although most mitigation studies are based on oral discourse (not excluding the written text, this research considers written texts as a means and an end, in the observation and description, since original versions are unchangeable; this opens the option to edit and modify, which is promoted, before the final version elaborated between students and researchers is reached. Some comments are included as the result of what is described above.

  10. Ideology and population theory.

    Harvey, D

    1974-01-01

    The ideological and ethical foundations of population theory are examined in the light of the supposed eithical neutrality of scientific enquiry. The works of Malthus, Ricardo, and Marx are contrasted and it is shown that their theories of population resulted in each case from the adoption of a particular kind of method--empiricism in Malthus, normative analytic "model building" in Ricardo, and dialectical materialism in Marx. It is shown that a Malthusian or neo-Malthusian view of the population problem is inevitable if enquiry is founded in empiricism or in normative analytics. The well-known disagreement between Malthusian and Marxian viewpoints therefore has its foundation in method. Most modern enquiry into the population-resources problem is dominated by empirical and analytic (including systems theory) approaches and consequently arrives at neo-Malthusian conclusions. The final section analyses the consequences of adopting a neo-Malthusian view, and it is shown that in a world dominated by an elite, this can frequently bring about the political, social, and economic repression of a non-elite. It is concluded that the choice of scientific method does not produce unbiased results and that the dominance of a certain conception of scientific method leads to the scientific support of a viewpoint used to justify repression of the underprivileged in society.

  11. Experimental cross-correlation nitrogen Q-branch CARS thermometry in a spark ignition engine

    Lockett, R. D.; Ball, D.; Robertson, G. N.

    2013-07-01

    A purely experimental technique was employed to derive temperatures from nitrogen Q-branch Coherent Anti-Stokes Raman Scattering (CARS) spectra, obtained in a high pressure, high temperature environment (spark ignition Otto engine). This was in order to obviate any errors arising from deficiencies in the spectral scaling laws which are commonly used to represent nitrogen Q-branch CARS spectra at high pressure. The spectra obtained in the engine were compared with spectra obtained in a calibrated high pressure, high temperature cell, using direct cross-correlation in place of the minimisation of sums of squares of residuals. The technique is demonstrated through the measurement of air temperature as a function of crankshaft angle inside the cylinder of a motored single-cylinder Ricardo E6 research engine, followed by the measurement of fuel-air mixture temperatures obtained during the compression stroke in a knocking Ricardo E6 engine. A standard CARS programme (SANDIA's CARSFIT) was employed to calibrate the altered non-resonant background contribution to the CARS spectra that was caused by the alteration to the mole fraction of nitrogen in the unburned fuel-air mixture. The compression temperature profiles were extrapolated in order to predict the auto-ignition temperatures.

    El Río de la Plata (RdlP) presenta significativas variaciones naturales (hidrodinámicas y oceanográficas) asociadas a diferentes condiciones climáticas. El propósito de este trabajo es inferir los cambios de aportes continentales de sedimentos y su relación con las variaciones hidrológicas del Río de la Plata, a través del análisis de proxies sedimentológicos y geoquímicos en testigos de sedimentos de la plataforma interna uruguaya que registran los últimos 100 años, aproximadamente. A partir de la datación por 210Pb de dos testigos de sedimentos (GeoB 13813-4 y BAR1) se reconstruyó la geocronología del ambiente, y se relacionó con datos de las forzantes climáticas Pacific Decadal Oscillation, El Niño/La Niña Southern Oscillation, Atlantic Multidecadal Oscillation, y las anomalías hidrológicas de los ríos Paraná y Uruguay. Los valores más positivos y estables del Southern Oscillation Index, los cuales corresponden a fases La Niña, se observan en el periodo correspondiente entre 1910-1970, respecto al resto de la serie, donde se aprecia una mayor variabilidad y una tendencia hacia valores más negativos (eventos El Niño). Se hicieron dendrogramas (clustering) jerárquicos para ambos testigos. Para el testigo GeoB 13813-4, se utilizó la relación Ca/Ti y la granulometría, mientras que para BAR1 se recurrió a variables granulométricas y la tasa de sedimentación. El mayor aporte continental hacia la región de la plataforma adyacente al Río de la Plata registrado a partir del año 1970, podría ser el factor principal de los agrupamientos observados en los clusters para ambos testigos. Las agrupaciones mostraron una diferenciación en la década de 1970, lo que estaría asociado al aumento de los caudales de los ríos Paraná y Uruguay, durante las últimas tres décadas del siglo XX. Por otra parte se observa que la granulometría del testigo BAR1 presentó un mayor tamaño de grano y más variabilidad que en el caso del testigo Geo

    2007-06-01

    Full Text Available This study analyzes the labour productivity for the Italian regions estimating the Sylos Labini's function. In this function, in dynamic term, the labour productivity depends positively on market (Smith effect, on unit labour cost (organization's effect, on difference between wages and prices of machine (Ricardo effect and past investments, while it depends negatively on current investments (disturbance effect. According to the estimates, for the Italian regions, these three effects are significant; moreover the dimension of these effects are conditioned by sector and territorial peculiarities. In particular, the Smith effect could be determined by the phenomenon of labour hoarding for which during recession entrepreneur prefers to reduce utilization of workers that fire them. Finally, the significance of investments could be caused by an important multicollinearity between present and past investments.

These are hydrodynamic models for mono-component droplet heating and evaporation, taking into account the effects of the moving boundary due to evaporation, hydrodynamic models of multi-component droplet heating and evaporation, taking and not taking into account the effects of the moving boundary, new kinetic models of mono-component droplet heating and evaporation, and a model for mono-component droplet evaporation, based on molecular dynamics simulation. The results, predicted by the new models are compared with experimental data and the prehctions of the previously developed models where possible. © 2013 Asian Network for Scientific Information.

  3. A prediction study of a spark ignition supercharged hydrogen engine

    Al-Baghdadi, Maher A.R. Sadiq.; Al-Janabi, Haroun A.K. Shahad

    2003-01-01

    Hydrogen is found to be a suitable alternative fuel for spark ignition engines with certain drawbacks, such as high NO x emission and small power output. However, supercharging may solve such problems. In this study, the effects of equivalence ratio, compression ratio and inlet pressure on the performance and NO x emission of a four stroke supercharged hydrogen engine have been analyzed using a specially developed computer program. The results are verified and compared with experimental data obtained from tests on a Ricardo E6/US engine. A chart specifying the safe operation zone of the hydrogen engine has been produced. The safe operation zone means no pre-ignition, acceptable NO x emission, high engine efficiency and lower specific fuel consumption in comparison with the gasoline engine. The study also shows that supercharging is a more effective method to increase the output of a hydrogen engine rather than increasing the compression ratio of the engine at the knock limited equivalence ratio

    2012-08-01

    Full Text Available From Ricardo and Smith the deficits were seen as the one of „the most terrible scourges which was ever invented to afflict a nation” as a system which tends to make us less thrifty, to blind us to our real situation. In the twentieth century allowing deficits regardless of their destination opened the wrong door to excessive debt and vulnerable states to the credit markets. This paper aims at showing that currently many European Member States faced not only with high deficits and high stocks of public debt, which under normal conditions could be easier managed, but with the rejection and the lower confidence of investors and financial institution, with higher burden of interests and significant loss of growth perspective.

    Full Text Available This paper presented an analysis of the gear shifting performances of a multipurpose vehicle transmission in driving condition by Ricardo's Gear Shift Quality Assessment (GSQA system. The performances of the transmission included the travel and effort of the gear shift lever and synchronizing time. The mathematic models of the transmission including the gear shift mechanism and synchronizer were developed in MATLAB. The model of the gear shift mechanism was developed to analyze the travel map of the gear shift lever and the model of the synchronizer was developed to obtain the force-time curve of the synchronizer during the slipping time. The model of the synchronizer was used to investigate the relationship between the performances of the transmission and the variation of parameters during gear shifting. The mathematic models of the gear shift mechanism and the synchronizer provided a rapid design and verification method for the transmission with ring spring.

    2000-04-01

    It is well known that the operation of dual fuel engines at lower loads suffers from lower thermal efficiency and higher unburned percentages of fuel. To rectify this problem, tests have been conducted on a special single cylinder compression ignition research engine (Ricardo E6) to investigate the effect of pilot fuel quantity on the performance of an indirect injection diesel engine fuelled with gaseous fuel. Diesel fuel was used as the pilot fuel and methane or propane was used as the main fuel which was inducted into the intake manifold to mix with the intake air. Through experimental investigations, it is shown that, the low efficiency and excess emissions at light loads can be improved significantly by increasing the amount of pilot fuel, while increasing the amount of pilot fuel at high loads led to early knocking.

  12. Reducing the viscosity of Jojoba Methyl Ester diesel fuel and effects on diesel engine performance and roughness

    Selim, Mohamed Y.E.

    2009-01-01

    An experimental investigation has been carried out to test two approaches to reduce the viscosity of the Jojoba Methyl Ester (JME) diesel fuel. The first approach is the heating of the fuel to two temperatures of 50 and 70 deg. C as compared to the base ambient temperature and to diesel fuel too. The second approach is adding one chemical which is considered by its own as alternative and renewable fuel which is Diethyl Ether (DEE). The viscosity has been reduced by both methods to close to diesel values. The performance of a diesel engine using those fuels has been tested in a variable compression research engine Ricardo E6 with the engine speed constant at 1200 rpm. The measured parameters included the exhaust gas temperature, the ignition delay period, the maximum pressure rise rate, maximum pressure, and indicated mean effective pressure and maximum heat release rate. The engine performance is presented and the effects of both approaches are scrutinized.

    INSTEAD: a randomised switch trial of indacaterol versus salmeterol/fluticasone in moderate COPD Authors: Rossi A, van der Molen T, Ricardo del Olmo, et al. Eur Respir J 2014; 44: 6, 1548-1556 SUMMARY: Inhaled corticosteroids (ICS) remain a highly controversial treatment for stable chronic obstructive pulmonary disease (COPD). Data linking high-dose ICS with complications, such as pneumonia and fractures, has necessitated a re-evaluation of their role in COPD management. Guidelines currently suggest ICS for patients with a forced expiratory volume in 1 s (FEV1) <50% predicted (or <60% in some regions) and a history of exacerbations. Nevertheless, it is well known that ICS and combination ICS/long-acting β-agonist (LABA) treatments are commonly used outside these groups. In view of the increasingly recognised dangers of ICS treatment, data demonstrating the safety of discontinuing ICS treatment is welcome.

This mark of respect is made by analyzing the film La cuna vacía (The Empty Cradle, which homage him during 1949. Exceeding the nationalist and social context of its premiere, this simple and slightly sweetened version of Gutiérrez’s fragment of life may be now rescued, in critical axiological moments in our country, because of its didactic and motivational nature and especially because of its build-up-values stimulation during health sciences undergraduate and graduate education.

  19. THE EFFECTS OF INCREASE THE COMPRESSION RATIO ON PERFORMANCE OF A DIESEL ENGINE

    Adnan PARLAK

    2003-02-01

    Full Text Available An optimisation of the Diesel cycle has been performed for power output and thermal efficiency with respect to compression ratio for various extreme temperature ratio. The relation between compression ratio and extreme temperature ratio, which gives optimum performance is derived. As the compression ratio of the diesel engine is increased in comparison to the optimum value of the engine, it is shown that the performance of the engine is decreased. The experimental study agrees with these results. In this study, compression ratio of a single cylinder pre-combustion chamber variable compression ratio Ricardo E6 type engine with the optimum compression ratio of 18.20 was increased to 19.60. As a results of this increase, specific fuel consumption was increased about 8 % and brake thermal efficiency was decreased about 7.5 %.

  20. Efficiency of a new internal combustion engine concept with variable piston motion

    Dorić Jovan Ž.

    2014-01-01

    Full Text Available This paper presents simulation of working process in a new IC engine concept. The main feature of this new IC engine concept is the realization of variable movement of the piston. With this unconventional piston movement it is easy to provide variable compression ratio, variable displacement and combustion during constant volume. These advantages over standard piston mechanism are achieved through synthesis of the two pairs of non-circular gears. Presented mechanism is designed to obtain a specific motion law which provides better fuel consumption of IC engines. For this paper Ricardo/WAVE software was used, which provides a fully integrated treatment of time-dependent fluid dynamics and thermodynamics by means of onedimensional formulation. The results obtained herein include the efficiency characteristic of this new heat engine concept. The results show that combustion during constant volume, variable compression ratio and variable displacement have significant impact on improvement of fuel consumption.

    2016-01-01

    Full Text Available For over a century the people of Bahia Blanca, Argentinian port city located at the south west of the province of Buenos Aires, they have imagined it and defined it not only as part of the Patagonian territories but also as their legitimate political, economic and cultural center. The aim of historicizing and questioning this idea, trying to account for the interests that were mobilized, the ideological postures that hinted, and the impact it had on the effective regional layout, is what motivates our research. To that end, this article does focus on economic and infrastructural dimension that some debates of mid-twentieth century used simultaneously as evidence and as ultimate goal of this alleged hegemony. For this purpose, we will analyze the writings of Domingo Pronsato and Ricardo M. Ortiz whom, from different geopolitical perspectives, devised specific roles for the city that suited their plans for the regional development of Patagonia.

  9. Representations of desires in some recent gay Asian-American writings.

    Murray, Stephen O

    2003-01-01

    This article explores conceptions of same-sex sexual behavior and desires by American gay males who grew up in Pacific Island or Asian societies. In the absence of systematic survey data, representations, which are not assumed to be autobiographical, by two South Asian émigrés to Canada (Badruddin Khan and Shyam Selvadurai), two second generation Filipino-Americans (Joël Tan and Ricardo Ramos), a second generation Chinese-Hawaiian (Norman Wong) and three men of Chinese descent born and raised in Southeast Asia (Lawrence Chua, Justin Chin, and T. C. Huo) are examined. The unsatisfying script of sexual submission of Asians to whites is particularly central, except for the South Asians. These books provide recurrent evidence of role distance, of switching roles (often without rewriting a dominance-submission conception of insertion-reception) and of some degree of reconceiving the (sexual) self.

    2009-07-01

    This book sets the last few years dramatic oil news into a context which until now has been missing in the Norwegian debate. The starting point is an analysis of what the classical economists - from Smith and Ricardo to Marx and George - would have called the oil companies special political economy. The book shows that which is good for the new Statoil, nearly never will be good for Norway and the rest of the world. It shows how a small elite has secured a good grip on straws into the great oil wealth, how the foundation, in international context presented as a successful Norwegian oil policy, is about to break down and how the great internationalization project which lay behind, will change Norway's relationship to the world - forever.

Pío participation was enthusiastic although brief, while his brother Ricardo was better recognized for his work as stage designer. Rivas Cherif participated in numerous performances and his coherence with the new theatre model that he defended was unanimously praised. Eusebio de Gorbea was considered the best actor among the playwrights, although his more appreciated characteristics like tone, gesture and roughness approached him to naturalism. The interpretative work of these authors as components of a group, whose nucleus remained amongst successive renovation attempts, is also recognized by its discipline, renounce to individual success and subordination to scenic treatment.En los ensayos de renovación teatral de los años veinte, varios dramaturgos intervinieron como actores.

Las numerosas actuaciones de Rivas Cherif fueron unánimemente valoradas por su coherencia con los presupuestos del nuevo teatro que tanto defendió. Eusebio de Gorbea fue el dramaturgo más reconocido en su labor de actor, si bien sus rasgos más destacados, tono, ademán, rudeza le sitúan cercano al naturalismo. La labor interpretativa de estos autores como componentes de un grupo, cuyo núcleo se mantiene en los sucesivos intentos renovadores, es también alabada por su disciplina, renuncia al lucimiento y supeditación al tratamiento escénico.

  16. Effects of diluent admissions and intake air temperature in exhaust gas recirculation on the emissions of an indirect injection dual fuel engine

    The operation of Diesel engines on gaseous fuels, commonly known as dual fuel engines, uses Diesel fuel as the pilot fuel and gaseous fuel (methane and sometimes propane in the present work) as the main fuel. The gaseous fuel was inducted in the intake manifold to mix with the intake air. The investigation was conducted on a high speed indirect injection (Ricardo-E6) dual fuel engine and was concerned with the effects of exhaust gas recirculation (EGR) on the dual fuel engine combustion and emissions, in particular, the effects of intake air temperature and diluent admissions (N{sub 2} and CO{sub 2}) on combustion and emissions. The use of diluents to displace oxygen (O{sub 2}) in the intake air resulted in a reduction in the O{sub 2} supplied to the engine, increased the inlet charge thermal capacity (thermal effect) and, potentially, CO{sub 2} and N{sub 2} participated in the combustion process (chemical effect). In a separate series of tests, the temperature of the engine inlet charge was raised gradually in order to simulate the effect of mixing hot EGR with the engine inlet gaseous fuel air mixture. It was found that the admission of diluents resulted in reductions in the exhaust oxides of nitrogen (NO{sub x}). Higher inlet charge temperature increases the exhaust NO{sub x} but reduces the unburned hydrocarbon emissions. Finally, when carbon dioxide was added to the inlet gaseous fuel air charge, large reductions in NO{sub x} were observed. (author)

  17. An economic assessment of low carbon vehicles

    Summerton, P. [Cambridge Econometrics CE, Cambridge (United Kingdom); Harrison, P. [European Climate Foundation ECF, Brussels (Belgium)] (eds.)

    2013-03-15

    The study aimed to analyse the economic impacts of decarbonizing light duty vehicles. As part of the study, the impacts of the European Commissions proposed 2020 CO2 regulation for cars and vans have been assessed. The analysis showed that a shift to low-carbon vehicles would increase spending on vehicle technology, therefore generating positive direct employment impacts, but potentially adding 1,000-1,100 euro to the capital cost of the average new car in 2020. However, these additional technology costs would be offset by fuel savings of around 400 euro per year, indicating an effective break-even point for drivers of approximately three years. At the EU level, the cost of running and maintaining the European car fleet would become 33-35 billion euro lower each year than in a 'do nothing scenario' by 2030, leading to positive economic impacts including indirect employment gains. Data on the cost of low carbon vehicle technologies has largely been sourced from the auto industry itself, with the study supported by a core working group including Nissan, GE, the European Association of Automotive Suppliers (CLEPA), and the European Storage Battery Manufacturers Association (Eurobat). Fuel price projections for the study were based on the IEA's World Energy Outlook, while technical modelling was carried out using the transport policy scoping tool SULTAN (developed by Ricardo-AEA for the European Commission) and the Road Vehicle Cost and Efficiency Calculation Framework, also developed by Ricardo-AEA. Macro-economic modelling was done using the E3ME model, which has previously been used for several European Commission and EU government impact assessments. This report focuses on efficient use of fossil fuels in internal combustion- and hybrid electric vehicles. It will be followed by a second report, which will focus on further reducing the use of fossil fuels by also substituting them with domestically produced energy carriers, such as electricity and

    Full Text Available As revisões sobre os estudos clássicos de família no Brasil convergem na crítica ao patriarcalismo como modelo genérico e fixo de descrição dessa instituição, propondo que a família brasileira era uma pluralidade dispersa de experiências. Sugerimos que já nas narrativas ensaísticas sobre a identidade nacional existem modelos plurais de família brasileira, diversificados em termos da compreensão dos arranjos locais de relações familiares. Com esse objetivo, relemos, sob o eixo família-nação-região, dois conjuntos de ensaístas significativos para a construção de identidades regionais particulares (primeiro, Alfredo Ellis Jr. e Cassiano Ricardo; segundo, Alceu Amoroso Lima e Sylvio de Vasconcellos, pensadores/produtores de visões de São Paulo e de Minas Gerais, respectivamente, enquanto culturas e sociedades em grande parte caracterizadas por suas experiências de organização familiar própria.Revisions of classical studies of the family in Brazil agree in criticizing patriarchalism as a general and fixed model describing this institution, arguing that the Brazilian family was a plurality of dispersed experiences. We suggest that in the essay narratives of national identity there are already plural models of the Brazilian family, which are diversified according to local arrangements of family relations. Considering the themes family-nation-region, we review the work of two groups of important essayists on the construction of particular regional identities: Alfredo Ellis Jr. e Cassiano Ricardo; Alceu Amoroso Lima e Sylvio de Vasconcellos. We argue that these essayists articulated visions of São Paulo and Minas Gerais as cultures and societies characterized in a significant way by experiences of a proper family organization.

  1. Accumulation and foreign trade from a center-periphery perspective Acumulación y comercio exterior desde una perspectiva centro-periferia

    García José Guillermo

    1998-06-01

    Full Text Available The theories which have attempted to explain the insertion of the countries of the periphery in the international division of labor haven't been able to explain in a satisfactory way the economic foundations and mechanisms of foreign trade in that contexto To understand the logic of the mechanism of peripheral insertion, the function served by foreign
    trade in the capital accumulation process must be analyzed. By going back to this problem in the classical analysis, some pieces of a new puzzle can be found. Smith's theory of the extension of the market, the structural heterogeneity of capitalism expressed in the differentiation of national price systems and profit rates according to Ricardo, and the foundations of the forms of mercantile and industrial accumulation in Marx are the new elements. The profit rate improves the conditions of accumulation when it exploits the differences in the national price systems. In the process of accumulation, the mechanisms of industrial accumulation operate in the interior, and they are strengthened by the
    mechanisms of mercantile accumulation which operate in external trade. As a consequence, the extension of the market outward to the periphery is only viable to the extent that this zone offers compensations which improve the condi tions determining the rates of profi t and accumulation

There are only a few viable options of psychosocial interventions that deal with this specific topic; one of them is psychoeducation, a model that, although it has been used by practitioners for some time, only recently have studies shown its efficacy in clinical practice.Aim: To assess if patients undergoing psychosocial intervention in addition to a pharmacological treatment have better regulation of their biological rhythm than those only using medication.Method: This study is a randomized clinical trial that compares a standard medication intervention to an intervention combined with drugs and psychoeducation. The evaluation of the biological rhythm was made using the Biological Rhythm Interview of Assessment in Neuropsychiatry, an 18-item scale divided in four areas (sleep, activity, social rhythm, and eating pattern. The combined intervention consisted of medication and a short-term psychoeducation model summarized in a protocol of six individual sessions of 1 hour each.Results: The sample consisted of 61 patients with bipolar II disorder, but during the study, there were 14 losses to follow-up. Therefore, the final sample consisted of 45 individuals (26 for standard intervention and 19 for combined.

  6. A hydrodynamic model for cooperating solidary countries

    De Luca, Roberto; Di Mauro, Marco; Falzarano, Angelo; Naddeo, Adele

    2017-07-01

    The goal of international trade theories is to explain the exchange of goods and services between different countries, aiming to benefit from it. Albeit the idea is very simple and known since ancient history, smart policy and business strategies need to be implemented by each subject, resulting in a complex as well as not obvious interplay. In order to understand such a complexity, different theories have been developed since the sixteenth century and today new ideas still continue to enter the game. Among them, the so called classical theories are country-based and range from Absolute and Comparative Advantage theories by A. Smith and D. Ricardo to Factor Proportions theory by E. Heckscher and B. Ohlin. In this work we build a simple hydrodynamic model, able to reproduce the main conclusions of Comparative Advantage theory in its simplest setup, i.e. a two-country world with country A and country B exchanging two goods within a genuine exchange-based economy and a trade flow ruled only by market forces. The model is further generalized by introducing money in order to discuss its role in shaping trade patterns. Advantages and drawbacks of the model are also discussed together with perspectives for its improvement.

    Full Text Available Ricardo A Tan1, Jonathan Corren21California Allergy and Asthma Medical Group, Los Angeles, CA; 2Allergy Research Foundation, Los Angeles, CA, USAAbstract: Inhaled corticosteroids (ICS have proven to be the most effective and essential therapy for the treatment of bronchial asthma. The 2007 National Asthma Education and Prevention Program guidelines recommend ICS as preferred therapy for patients with mild to severe persistent asthma. Mometasone furoate (MF is a relatively new ICS agent with high affinity for the glucocorticoid receptor. It is approved in the US for maintenance treatment of asthma for patients 4 years of age and older. It has been shown to be well tolerated with no significant adverse side effects observed in clinical trials and post-marketing surveillance. The efficacy of mometasone furoate has been established in large, well-designed studies. In patients with persistent asthma previously treated either with short-acting beta-agonists alone or twice-daily maintenance therapy with ICS, once-daily MF has been shown to be superior to placebo in improving lung function, symptom control, and quality of life; and has shown comparable efficacy compared with budesonide, beclomethasone, and fluticasone. Twice-daily dosing with MF has been demonstrated to successfully allow for reduction or elimination of oral corticosteroids in severe asthmatics.Keywords: inhaled steroids, mometasone furoate, once-daily dosing, asthma, stepwise approach

  10. [Diagnosis of congenital endocrinological disease in newborns with prolonged jaundice and hypoglycaemia].

    Braslavsky, D; Keselman, A; Chiesa, A; Bergadá, I

    2012-03-01

    The association of prolonged neonatal jaundice and hypoglycaemia may be secondary to an endocrinological disease. Pituitary insufficiency and primary adrenal insufficiency are the most likely endocrine diseases that need to be ruled out. We retrospectively analysed the clinical and laboratory characteristics of thirteen patients referred to the Hospital de Niños Ricardo Gutiérrez between years 2003 and 2008 due to prolonged neonatal jaundice and hypoglycaemia secondary to pituitary insufficiency in twelve patients, and in one secondary to primary adrenal insufficiency. All patients had a history of neonatal hypoglycaemia. Ten patients had conjugated hyperbilirubinaemia and six also had elevated transaminases. Combined pituitary hormone deficiency was observed in the twelve hypopituitarism patients. Hormonal replacement normalised liver function and resolved the prolonged jaundice in all the patients. None of them underwent liver biopsy. Hypoglycaemia also remitted after hormonal therapy. Prolonged or cholestatic jaundice associated with neonatal hypoglycaemia is highly likely to be due to pituitary hormone deficiency or primary adrenal insufficiency. Early diagnosis and treatment of these children reverts the prolonged jaundice and prevents morbidity and mortality due to recurrent hypoglycaemia and hormone deficiencies.

    After more than 40 years of democracy and 30 years of European integration, Portugal has bridged the research gap it had previously. However, when compared to global and European research policies, Portugal still has a long way go regarding investment in research and development. Health Research in Portugal has been managed by the Fundação para a Ciência e Tecnologia and the National Health Institute Doctor Ricardo Jorge, and it has not been a political priority, emphasized by the absence of a national scientific research plan for health, resulting in a weak coordination of actors in the field. The strategic guidelines of the 2004 - 2010 National Health Plan are what comes closest to a health research policy, but these were not implemented by the institutions responsible for scientific research for the health sector. Trusting that adopting a strategy of incentives to stimulate health research is an added-value for the Portuguese health system, the authors present five strategic proposals for research in health in Portugal.

    The Passagem granite includes stocks, plugs and dikes located in the Ricardo Franco hill - Vila Bela da Santissima Trindade region - state of Mato Grosso, central Brazil. The Passagem Granite is included in the Paragua terrane - SW Amazonian Craton. It consists of isotropic monzogranite, sienogranite and more rarely granodiorites with leucocratic dark gray to white color. These rocks range from hypidomorphic inequigranular to xenomorphic texture, fine to medium grained. Biotite is the only primary mafic present as essential phase and characterize an expanded slightly acid sequence formed by a sub-alkaline magmatism of high-potassium calc-alkaline, slightly peraluminous composition from arc magmatic tectonic environment during a post-collisional period. Mechanism of fractional crystallization of plagioclase, biotite, titanite, apatite and zircon associated with simultaneous crustal assimilation are suggested for the evolution of these rocks. The results support the hypothesis of a post-collisional magmatism in the Paragua terrane at 1284 +- 20 Ma corresponding to the crystallization age of the Passagem granite. This paper propose that Passagem Granite represents as an extension in Brazilian terrane of the Pensamiento Granitoid Complex. (author)

    Full Text Available Eli Heckscher was not only author of extensive investigations into economic history. He was also skillful in depicting phenomena in small format in encyclopædias, journals and newspapers. This article presents Heckscher as portrait maker of economic scholars. In these portraits—what he emphasized, what he praised, what he criticized—one can discern the stance of the portrait maker himself. Overall, his portraits are permeated by admiration of sharp theoretical analyses and massive economic historical investigations. He admires the founding fathers of political economy, Adam Smith and David Ricardo, stresses continuity in the development of economic thought, praises humble innovators like David Davidson, Knut Wicksell and Alfred Marshall and denounces (what he perceives as pretentious innovators like Gustav Cassel and John Maynard Keynes. He is critical towards economists who attempt to break out of the classical and neoclassical tradition, especially representatives of the German historical school, and what he judges to be a new type of mercantilism, represented by Bertil Ohlin and Keynes. At the same time he appreciates voluminous and solid investigations into economic history, even if performed without theoretical beacons, by scholars like William Cunningham, William Ashley, John Clapham, Marc Bloch, Richard Ehrenberg and Werner Sombart.

    Maqueda, Ricardo; Levinton, Fred M.

    2011-01-01

    Nova Photonics, Inc. has a collaborative effort at the National Spherical Torus Experiment (NSTX). This collaboration, based on fast imaging of visible phenomena, has provided key insights on edge turbulence, intermittency, and edge phenomena such as edge localized modes (ELMs) and multi-faceted axisymmetric radiation from the edge (MARFE). Studies have been performed in all these areas. The edge turbulence/intermittency studies make use of the Gas Puff Imaging diagnostic developed by the Principal Investigator (Ricardo Maqueda) together with colleagues from PPPL. This effort is part of the International Tokamak Physics Activity (ITPA) edge, scrape-off layer and divertor group joint activity (DSOL-15: Inter-machine comparison of blob characteristics). The edge turbulence/blob study has been extended from the current location near the midplane of the device to the lower divertor region of NSTX. The goal of this effort was to study turbulence born blobs in the vicinity of the X-point region and their circuit closure on divertor sheaths or high density regions in the divertor. In the area of ELMs and MARFEs we have studied and characterized the mode structure and evolution of the ELM types observed in NSTX, as well as the study of the observed interaction between MARFEs and ELMs. This interaction could have substantial implications for future devices where radiative divertor regions are required to maintain detachment from the divertor plasma facing components.

    Hydrogen is found to be a suitable alternative fuel for spark ignition engines with certain drawbacks, such as high NO{sub x} emission and small power output. However, supercharging may solve such problems. In this study, the effects of equivalence ratio, compression ratio and inlet pressure on the performance and NO{sub x} emission of a four stroke supercharged hydrogen engine have been analyzed using a specially developed computer program. The results are verified and compared with experimental data obtained from tests on a Ricardo E6/US engine. A chart specifying the safe operation zone of the hydrogen engine has been produced. The safe operation zone means no pre-ignition, acceptable NO{sub x} emission, high engine efficiency and lower specific fuel consumption in comparison with the gasoline engine. The study also shows that supercharging is a more effective method to increase the output of a hydrogen engine rather than increasing the compression ratio of the engine at the knock limited equivalence ratio.

    In 1989 it was found that in each unit of the MAPS Candu nuclear power station in India the centre portion of the heavy water inlet manifold opposite the 300 mm inlet pipe had torn away. Equipment for remote inspection, repair and removal of debris in an area with constricted and difficult access and radiation fields of about 10 4 Gy/h was developed by Ricardo Hitec of the United Kingdom. This consists of a work performing manipulator, TV viewing systems and a posting tube manipulator for insertion of tools and debris containers into the calandria. A variety of special end effector and tools were also developed jointly with AEA Technology. A first repair campaign was carried out on Unit 1 in 1991. Following a detailed TV survey of the damage a reappraisal of the situation was undertaken and a programme of equipment enhancement carried out. In July 1992 a second repair campaign took place on Unit 2. The difficulties encountered and the degree of success achieved are described. Work proceeded at an intensive level for 14 days when the campaign was ended in view of the exhaustion both of personnel and the equipment. Although more work could have been done a major improvement had been achieved. (UK)

    2013-05-01

    Full Text Available Hector Miranda-Grajales, Joy Hao, Ricardo A CrucianiDepartment of Pain Medicine and Palliative Care, Beth Israel Medical Center, New York, NY, USAAbstract: It has been proposed that some deaths attributed to methadone are related to prolongation of the QTc interval; however, there are no clear recommendations on electrocardiogram (ECG monitoring in patients undergoing intravenous methadone infusion. This is a report on a patient receiving methadone intravenous patient-controlled analgesia titration for the treatment of chronic pain. Initially, her daily ECGs showed QTc intervals within normal limits; however, she experienced a rapid increase in QTc interval from 317 ms to 784 ms within a 24-hour period after methadone had been discontinued for excessive sedation. QTc interval greater than 500 ms is considered to be high risk for the fatal arrhythmia Torsades de Pointes. Daily ECGs did not detect a gradual increase in the QTc interval that would have alerted the medical staff of the need to decrease or stop the methadone before reaching a prolonged QTc interval associated with cardiotoxicity. In selected cases where aggressive methadone titration is required, more intensive monitoring, such as telemetry or ECG determinations every 12 hours, might help detect changes in QTc interval duration that might otherwise be missed by daily ECG determinations.Keywords: methadone, QTc prolongation, opioids, opioid side effects, IVPCA methadone

    2009-01-01

    The Argon inert gas is used to dilute the intake air of a spark ignition engine to decrease nitrogen oxides and improve the performance of the engine. A research engine Ricardo E6 with variable compression was used in the present work. A special test rig has been designed and built to admit the gas to the intake air of the engine for up to 15% of the intake air. The system could admit the inert gas, oxygen and nitrogen gases at preset amounts. The variables studied included the engine speed, Argon to inlet air ratio, and air to fuel ratio. The results presented here included the combustion pressure, temperature, burned mass fraction, heat release rate, brake power, thermal efficiency, volumetric efficiency, exhaust temperature, brake specific fuel consumption and emissions of CO, CO 2 , NO and O 2 . It was found that the addition of Argon gas to the intake air of the gasoline engine causes the nitrogen oxide to reduce effectively and also it caused the brake power and thermal efficiency of the engine to increase. Mathematical program has been used to obtain the mixture properties and the heat release when the Argon gas is used.

    At last year's THE Port hackathon, the Better Body Bags team emerged with a new approach to body-bag technology that catered to the needs of humanitarian organisations. What started as a weekend hack has developed into a full-scale R& D project, as the team joins forces with the International Committee of the Red Cross (ICRC) to put their body bags into production.   Ricardo Páramo Peláez, the team's product designer, presented the first prototype at THE Port Hackathon 2014. The "body" is his fellow team mate, João Cordovil Bárcia. A typical body bag is essentially a long plastic bag with handles: it breaks, leaks, smells and isn't cheap. “Little thought had gone into using new technology to improve the bags,” says Tim Head, an LHCb physicist who is leading the Better Body Bags team. “Simple improvements can keep bodies in better condition, thus improving the identification ...

    Global demands on fuel economy and lower emissions from automotive vehicles have had a large impact on the development of engine management systems (EMS) in recent years. However, despite the advances in system hardware, the software programmed into these systems has yet to utilise the full potential of modern control methodologies. Model based control and diagnostics is the next step forward in the development of EMS software with the potential of providing improvements in cost, efficiency, emissions and comfort. However, the full utilisation of such techniques requires very close monitoring of engine conditions. This is made possible with the advent of new inexpensive sensor technology that can withstand the harsh environment of the combustion chamber. To exploit the above advances, the AENEAS collaborative project is being carried out by Ricardo, DaimlerChrysler and Kistler, with financial support from the European Commission and Swiss government, and has the objective of realising the benefits of cylinder pressure based engine management system (CPEMS) technology. This paper describes the application of CPEMS technology to a spark ignition (SI) engine. It describes how the combination of model based algorithms, incorporating physical principles, and cylinder pressure sensing can provide an effective means of engine control and diagnostics. (orig.)

    In order to fulfill future emissions and OBD regulations, whilst meeting increasing demands for driveability and refinement, new technologies for SI engines have to be found in terms of sensors and algorithms for engine control units. One promising way, explored in the AENEAS collaborative project between DaimlerChrysler, Kistler, Ricardo and the European Commission, is to optimize the behavior of the system by using in-cylinder measurements and analysing them with modern control algorithms. In this paper a new engine management system based on combustion pressure sensing is presented. The pressure sensor is designed to give a reliable and accurate signal of the full pressure trace during a working cycle. With the application of new technologies low cost manufacturing appears to be achievable, so that an application in mass production can be considered. Furthermore, model-based algorithms were developed to allow optimal control of the engine based on the in-cylinder measurements. The algorithms incorporate physical principles to improve efficiency, emissions and to reduce the parameterisation effort. In the paper, applications of the combustion pressure signal for air mass estimation, knock detection, ignition control cam phase detection and diagnosis are discussed. (author)

    Selim, Mohamed Y.E. [United Arab Emirates Univ., Dept. of Mechanical Engineering, Al-Ain (United Arab Emirates)

    2003-03-01

    Combustion pressure rise rate and thermal efficiency data are measured and presented for a dual fuel engine running on a dual fuel of Diesel and compressed natural gas and utilizing exhaust gas recirculation (EGR). The maximum pressure rise rate during combustion is presented as a measure of combustion noise. The experimental investigation on the dual fuel engine revealed the noise generated from combustion and the thermal efficiency at different EGR ratios. A Ricardo E6 Diesel version engine is converted to run on a dual fuel of Diesel and compressed natural gas and having an exhaust gas recycling system is used throughout the work. The engine is fully computerized, and the cylinder pressure data and crank angle data are stored in a PC for offline analysis. The effects of EGR ratio, engine speeds, loads, temperature of recycled exhaust gases, intake charge pressure and engine compression ratio on combustion noise and thermal efficiency are examined for the dual fuel engine. The combustion noise and thermal efficiency of the dual fuel engine are found to be affected when EGR is used in the dual fuel engine. (Author)

    2000-01-01

    Diesel engines operating on gaseous fuels are commonly known as dual-fuel engines. In the present work, a single-cylinder, compression ignition, indirect injection research (Ricardo E6) engine has been installed at United Arab Emirates University for investigation of the exhaust emissions when the engine is operating as a dual-fuel engine. The influence of changes in major operating and design parameters, such as the concentration of gaseous fuel in the cylinder charge, pilot fuel quantity, injection timing and intake temperature, on the production of exhaust emissions was investigated. Diesel fuel was used as the pilot fuel, while methane or propane was used as the main fuel which was inducted in the intake manifold and mixed with the intake air. The experimental investigations showed that the poor emissions at light loads can be improved significantly by increasing the concentration of gaseous fuel (total equivalence ratio), employing a large pilot fuel quantity, advancing the injection timing of the pilot fuel and increasing the intake temperature. It is demonstrated that, in general, any measure that tends to increase the size of the combustion regions within the overly lean cylinder charge will reduce markedly the concentrations of unburned hydrocarbons and carbon monoxide in the exhaust gases.

  17. Sensitivity of dual fuel engine combustion and knocking limits to gaseous fuel composition

    Selim, M.Y.E. [United Arab Emirates University, Al-Ain (United Arab Emirates). Dept. of Mechanical Engineering

    2004-02-01

    Combustion noise, knock and ignition limits data are measured and presented for a dual fuel engine running on dual fuels of Diesel and three gaseous fuels separately. The gaseous fuels used are liquefied petroleum gas, pure methane and compressed natural gas mixture. The maximum pressure rise rate during combustion is presented as a measure of combustion noise, and the knocking and ignition limits are presented as torque output at the onset of knocking and ignition failure. Experimental investigation on the dual fuel engine revealed the noise generated from combustion, knocking and ignition limits for all gases at different design and operating conditions. A Ricardo E6 Diesel version engine is converted to run on dual fuel of Diesel and the tested gaseous fuel and is used throughout the work. The engine is fully computerized, and the cylinder pressure data, crank angle data and engine operating variables are stored in a PC for off line analysis. The effects of engine speeds, loads, pilot injection angle, pilot fuel quantity and compression ratio on combustion noise, knocking torque, thermal efficiency and maximum pressure are examined for the dual engine running on the three gaseous fuels separately. The combustion noise, knocking and ignition limits are found to relate to the type of gaseous fuels and to the engine design and operating parameters. (author)

    2005-05-01

    This paper presents an analysis of the cycle-to-cycle combustion variation as reflected in the combustion pressure data of a single cylinder, naturally aspirated, four stroke, Ricardo E6 engine converted to run as dual fuel engine on diesel and gaseous fuel of LPG or methane. A measuring set-up consisting of a piezo-electric pressure transducer with charge amplifier and fast data acquisition card installed on an IBM microcomputer was used to gather the data of up to 1200 consecutive combustion cycles of the cylinder under various combination of engine operating and design parameters. These parameters included type of gaseous fuel, engine load, compression ratio, pilot fuel injection timing, pilot fuel mass, and engine speed. The data for each operating conditions were analyzed for the maximum pressure, the maximum rate of pressure rise representing the combustion noise, and indicated mean effective pressure. The cycle-to-cycle variation is expressed as the mean value, standard deviation, and coefficient of variation of these three parameters. It was found that the type of gaseous fuel and engine operating and design parameters affected the combustion noise and its cyclic variation and these effects have been presented. 21 refs., 6 figs., 1 tab.

    Combustion pressure data are measured and presented for a dual fuel engine running on dual fuel of diesel and compressed natural gas, and compared to the diesel engine case. The maximum pressure rise rate during combustion is presented as a measure of combustion noise. Experimental investigation on diesel and dual fuel engines revealed the noise generated from combustion in both cases. A Ricardo E6 diesel version engine is converted to run on dual fuel of diesel and compressed natural gas and is used throughout the work. The engine is fully computerized and the cylinder pressure data, crank angle data are stored in a PC for off-line analysis. The effect of engine speeds, loads, pilot injection angle, and pilot fuel quantity on combustion noise is examined for both diesel and dual engine. Maximum pressure rise rate and some samples of ensemble averaged pressure-crank angle data are presented in the present work. The combustion noise, generally, is found to increase for the dual fuel engine case as compared to the diesel engine case. (Author)

  20. Analysis of the Scavenging Process of a Two-Stroke Free-Piston Engine Based on the Selection of Scavenging Ports or Valves

    2018-02-01

    Full Text Available The free-piston engine generator (FPEG is a linear energy conversion device with the objective of utilisation within a hybrid-electric automotive vehicle power system. In this research, the piston dynamic characteristics of an FPEG is compared with that of a conventional engine (CE of the same size, and the difference in the valve timing is compared for both port scavenging type and valve scavenging type, with the exhaust valve closing timing is selected as the parameter. A zero-dimensional simulation model is developed in Ricardo WAVE software (2016.1, with the piston dynamics obtained from the simulation model in Matlab/SIMULINK (R2017a. For the CE and FEPG using scavenging ports, in order to improve its power output to the same level as that of a CE, the inlet gas pressure is suggested to be improved to above 1.2 bar, approximately 0.2 bar higher than that used for a CE. If a CE cylinder with exhaust valves is adopted or referred to during the development of an FPEG prototype, the exhaust valve is suggested to be closed earlier to improve its power output, and a higher intake pressure is also suggested if its output power is expected to be the same or higher than that of a CE.

    The use of jojoba methyl ester as a pilot fuel was investigated for almost the first time as a way to improve the performance of dual fuel engine running on natural gas or liquefied petroleum gas (LPG) at part load. The dual fuel engine used was Ricardo E6 variable compression diesel engine and it used either compressed natural gas (CNG) or LPG as the main fuel and jojoba methyl ester as a pilot fuel. Diesel fuel was used as a reference fuel for the dual fuel engine results. During the experimental tests, the following have been measured: engine efficiency in terms of specific fuel consumption, brake power output, combustion noise in terms of maximum pressure rise rate and maximum pressure, exhaust emissions in terms of carbon monoxide and hydrocarbons, knocking limits in terms of maximum torque at onset of knocking, and cyclic variability data of 100 engine cycles in terms of maximum pressure and its pressure rise rate average and standard deviation. The tests examined the following engine parameters: gaseous fuel type, engine speed and load, pilot fuel injection timing, pilot fuel mass and compression ratio. Results showed that using the jojoba fuel with its improved properties has improved the dual fuel engine performance, reduced the combustion noise, extended knocking limits and reduced the cyclic variability of the combustion.

    2006-01-01

    An extended experimental study is conducted to evaluate and compare the use of various Diesel fuel supplements at blend ratios of 10/90 and 20/80, in a standard, fully instrumented, four stroke, direct injection (DI), Ricardo/Cussons 'Hydra' Diesel engine located at the authors' laboratory. More specifically, a high variety of vegetable oils or bio-diesels of various origins are tested as supplements, i.e. cottonseed oil, soybean oil, sunflower oil and their corresponding methyl esters, as well as rapeseed oil methyl ester, palm oil methyl ester, corn oil and olive kernel oil. The series of tests are conducted using each of the above fuel blends, with the engine working at a speed of 2000 rpm and at a medium and high load. In each test, volumetric fuel consumption, exhaust smokiness and exhaust regulated gas emissions such as nitrogen oxides (NO x ), carbon monoxide (CO) and total unburned hydrocarbons (HC) are measured. From the first measurement, specific fuel consumption and brake thermal efficiency are computed. The differences in the measured performance and exhaust emission parameters from the baseline operation of the engine, i.e. when working with neat Diesel fuel, are determined and compared. This comparison is extended between the use of the vegetable oil blends and the bio-diesel blends. Theoretical aspects of Diesel engine combustion, combined with the widely differing physical and chemical properties of these Diesel fuel supplements against the normal Diesel fuel, are used to aid the correct interpretation of the observed engine behavior

  5. Organic Rankine cycle - review and research directions in engine applications

    Panesar, Angad

    2017-11-01

    Waste heat to power conversion using Organic Rankine Cycles (ORC) is expected to play an important role in CO2 reductions from diesel engines. Firstly, a review of automotive ORCs is presented focusing on the pure working fluids, thermal architectures and expanders. The discussion includes, but is not limited to: R245fa, ethanol and water as fluids; series, parallel and cascade as architectures; dry saturated, superheated and supercritical as expansion conditions; and scroll, radial turbine and piston as expansion machines. Secondly, research direction in versatile expander and holistic architecture (NOx + CO2) are proposed. Benefits of using the proposed unconventional approaches are quantified using Ricardo Wave and Aspen HYSYS for diesel engine and ORC modelling. Results indicate that, the implementation of versatile piston expander tolerant to two-phase and using cyclopentane can potentially increase the highway drive cycle power by 8%. Furthermore, holistic architecture offering complete utilisation of charge air and exhaust recirculation heat increased the performance noticeably to 5% of engine power at the design point condition.

La presencia de la sangre ha comprometido estrategias metafóricas, como figuras de semejanza con las escenas de la violencia. Y también ha comprometido a la sangre misma como flujo abyecto, implicando estrategias metonímicas que generan poéticas secrecionales.

  11. Comparison of Engine Simulation Software for Development of Control System

    KinYip Chan

    2013-01-01

    Full Text Available Most commonly used commercial engine simulation packages generate detailed estimation of the combustion and gas flow parameters. These parameters are required for advanced research on fluid flow and heat transfer and development of geometries of engine components. However, engine control involves different operating parameters. Various sensors are installed into the engine, the combustion performance is recorded, and data is sent to engine control unit (ECU. ECU computes the new set of parameters to make fine adjustments to actuators providing better engine performance. Such techniques include variable valve timing, variable ignition timing, variable air to fuel ratio, and variable compression ratio. In the present study, two of the commercial packages, Ricardo Wave and Lotus Engine Simulation, have been tested on the capabilities for engine control purposes. These packages are compared with an in-house developed package and with reference results available from the literature. Different numerical experiments have been carried out from which it can be concluded that all packages predict similar profiles of pressure and temperature in the engine cylinder. Moreover, those are in reasonable agreement with the reference results while in-house developed package is possible to run simulations with changing speed for engine control purpose.

    Seven barley lines or varieties, each with a different gene at the Ml-a locus for resistance to Erysiphe graminis were intercrossed. Progeny testing of the F2s using two different fungal isolates per cross provided evidence that there are two or more loci in the Ml-a region. Apparent recombinants...... were also screened for recombination between the Hor1 and Hor2 loci which are situated either side of the Ml-a locus. The cross between Ricardo and Iso42R (Rupee) yielded one possible recombinant, with Ml-a3 and Ml-a(Rul) in the coupling phase; other recombinants had wild-type genes in the coupling...... phase. Iso20R, derived from Hordeum spontaneum 'H204', carrying Ml-a6, had an additional gene, in close coupling with Ml-a6, tentatively named Ml-aSp2 or Reglv, causing an intermediate infection type with isolate EmA30. It is suggested that Ml-a(Ar) in Emir and Ml-a(Rul), shown to differ from other Ml...

    2017-12-01

    Full Text Available In-cylinder air flow structures are known to strongly impact on the performance and combustion of internal combustion engines (ICE. Therefore the aim of this paper is to experimentally study an IC engine in-cylinder flow under steady-state conditions. Different methods can be used to characterize the in-cylinder flow which are optical engines and laser diagnostics, computational fluid dynamic and steady-state flow bench. Here we are concentrating on two different types of flow benches. The first (Ricardo uses the impulse torque meter method while the other (FEV uses the paddle wheel technique. The experiments were carried out on the same cylinder head and the same pressure difference across the inlet valves of 600 mmH2O in order to compare the results. The experimental results are presented in terms of the measured air flow rate, flow coefficient, discharge coefficient and non-dimensional rig tumble. Moreover, number of modifications were conducted on the FEV flow bench in order to apply particle image velocimetry measurements on the vertical tumble plane, which passing through the middle of the cylinder at different valve lifts. The results show that a reasonably good level of agreement can be achieved between both methods, providing the methods of calculations of the various parameters are consistent. Keywords: In-cylinder flow, Flow bench, Tumble motion, Flow coefficient, Particle image velocimetry

    Full Text Available The biocultural conservation and research initiative of Omora Ethnobotanical Park and the UNESCO Cape Horn Biosphere Reserve was born in a remote part of South America and has rapidly expanded to attain regional, national, and international relevance. The park and the biosphere reserve, led by Ricardo Rozzi and his team, have made significant progress in demonstrating the way academic research supports local cultures, social processes, decision making, and conservation. It is a dynamic hive of investigators, artists, writers, students, volunteers, and friends, all exploring ways to better integrate academia and society. The initiative involves an informal consortium of institutions and organizations; in Chile, these include the University of Magallanes, the Omora Foundation, and the Institute of Ecology and Biodiversity, and in the United States, the University of North Texas, the Omora Sub-Antarctic Research Alliance, and the Center for Environmental Philosophy at the University of North Texas. The consortium intends to function as a hub through which other institutions and organizations can be involved in research, education, and biocultural conservation. The park constitutes one of three long-term socio-ecological research sites in Chile of the Institute of Ecology and Biodiversity.

  18. Air pollution, land price development and assessment of immission control needs in urban development plans. The impact of immission pollution by sulphur dioxide and dust precipitation on property prices in residential areas of Dortmund and Duisburg

    Air pollution, land price development and assessment of immission control needs in urban development plans. The impact of immission pollution by sulphur dioxide and dust precipitation on property prices in residential areas of Dortmund and Duisburg. The focus of this thesis is on studying the links between property prices and air pollution. The ground rent theory which goes back to the 16th century provides the theoretical basis for this work. RICARDO put forward the theory, that air may, under certain circumstances, - as for instance different local air pollution levels or sensitivity of locals to air quality -, which did not apply 200 years ago actually produce rent. These circumstances do indeed apply widely today - different air pollution levels in urban areas are just a case in point. Various empiricial studies in the U.S. proved that air pollution with different substances does actually influence the value of property. The ground rent influenced by air pollution is called ''air rent''. This study contains empirical studies on the influence of air pollution by sulphur dioxide SO 2 and dust precipitation on general property prices in residential areas of Dortmund between 1979 and 1989 and Duisburg between 1981 and 1989.

  19. Free time minimizers for the three-body problem

    Moeckel, Richard; Montgomery, Richard; Sánchez Morgado, Héctor

    2018-03-01

    Free time minimizers of the action (called "semi-static" solutions by Mañe in International congress on dynamical systems in Montevideo (a tribute to Ricardo Mañé), vol 362, pp 120-131, 1996) play a central role in the theory of weak KAM solutions to the Hamilton-Jacobi equation (Fathi in Weak KAM Theorem in Lagrangian Dynamics Preliminary Version Number 10, 2017). We prove that any solution to Newton's three-body problem which is asymptotic to Lagrange's parabolic homothetic solution is eventually a free time minimizer. Conversely, we prove that every free time minimizer tends to Lagrange's solution, provided the mass ratios lie in a certain large open set of mass ratios. We were inspired by the work of Da Luz and Maderna (Math Proc Camb Philos Soc 156:209-227, 1980) which showed that every free time minimizer for the N-body problem is parabolic and therefore must be asymptotic to the set of central configurations. We exclude being asymptotic to Euler's central configurations by a second variation argument. Central configurations correspond to rest points for the McGehee blown-up dynamics. The large open set of mass ratios are those for which the linearized dynamics at each Euler rest point has a complex eigenvalue.

    1989-09-01

    Reviews historical concept of ground rents with reference to works of Adam Smith and David Ricardo and to 19th century capitalism and Marxism-Leninism. Asks whether mine rents can exist under a socialist system and examines theoretical basis for mine rents, which includes socio-economic aspects, geological conditions, proximity to markets and environmental considerations. Compares mine rents with agricultural land rents and analyzes value of end product (coal) and effect of pricing method on it. Explains pricing system in Czechoslovakia, which involves 3 groupings: coking coal, coke and energy coal (including briquets), the price of each of which is set according to average costs and geological conditions. Surplus revenue (or positive mine rent) only arises therefore at mines where the production costs are lower than fixed trade prices. Discusses in general terms application of new economic system (perestroika) to concept of mine rent and assessment of mine profitability and concludes that method of pricing solid fuels will play a decisive role. 4 refs.

  1. Farinelli o sobre las derivaciones vocales de esa vieja costumbre de castrar

    Óscar BOTTASSO

    2016-11-01

    Full Text Available La película representa algunos pasajes de la vida de Carlo Broschi, el célebre Farinelli, un castrato que hizo las delicias de tantísimos amantes de la ópera settecentista. De un reto callejero entre el joven cantante y un trompetista del cual Farinelli emerge triunfante gracias a su voz excepcional, George F. Haendel por ese entonces músico oficial de la corte inglesa y casi como de paso por el lugar le propone viajar a Londres. La oferta es desechada por Farinelli lo cual da lugar a una tirantez en la relación entre ambos, impregnada por antipatías pero al mismo tiempo un dejo de reconocimiento mutuo. En contraposición al escasamente abordado confinamiento de Farinelli en la corte española, en pleno apogeo de su carrera, el film abunda en mostrarnos las variadas visitas de los hermanos Broschi a distintos escenarios europeos, matizado por episodios donde lo seductor de su talante servía de disparador de numerables escenas amorosas finalmente efectivizadas por su hermano Ricardo, anatómicamente intacto. Un hecho que en función de la fisiopatología de un castrado prepuberal parece más sobrerepresentado que veraz.

  2. Concepts and Bounded Rationality: An Application of Niestegge's Approach to Conditional Quantum Probabilities

    Blutner, Reinhard

    2009-03-01

    Recently, Gerd Niestegge developed a new approach to quantum mechanics via conditional probabilities developing the well-known proposal to consider the Lüders-von Neumann measurement as a non-classical extension of probability conditionalization. I will apply his powerful and rigorous approach to the treatment of concepts using a geometrical model of meaning. In this model, instances are treated as vectors of a Hilbert space H. In the present approach there are at least two possibilities to form categories. The first possibility sees categories as a mixture of its instances (described by a density matrix). In the simplest case we get the classical probability theory including the Bayesian formula. The second possibility sees categories formed by a distinctive prototype which is the superposition of the (weighted) instances. The construction of prototypes can be seen as transferring a mixed quantum state into a pure quantum state freezing the probabilistic characteristics of the superposed instances into the structure of the formed prototype. Closely related to the idea of forming concepts by prototypes is the existence of interference effects. Such inference effects are typically found in macroscopic quantum systems and I will discuss them in connection with several puzzles of bounded rationality. The present approach nicely generalizes earlier proposals made by authors such as Diederik Aerts, Andrei Khrennikov, Ricardo Franco, and Jerome Busemeyer. Concluding, I will suggest that an active dialogue between cognitive approaches to logic and semantics and the modern approach of quantum information science is mandatory.

  4. Renda da Terra, Expansão da Fronteira Imobiliária, Gentrificação e Exclusão no Brasil (2009-2015

    Fabian Scholze Domingues

    2016-01-01

    Full Text Available This article uses the differential rent theory of David Ricardo to offer an economic explanation for the recent rise in property prices and rents seen in Brazil between 2009 and 2015. Unlike the advocates of the existence of a speculative bubble in the housing market, it is proposed that increase price in rents and properties come from the expansion of the urban frontier, largely caused by the public policies of housing geared to low-income classes. As in the Ricardian model, the analysis is done by dividing the society into three social classes: workers, capitalists and rentiers. It is argued that nominal prices will not decrease, as would be expected if the origin of the phenomenon had been located in the credit market. Thus, the main beneficiaries of this policy is the class of rentiers, not the worker class, neither the capitalist class. The differential rent theory also allows explain movements of gentrification and exclusion, ie revaluation central areas with good urban infrastructure, but degraded, resulting in the exclusion of large population, removed to areas far from the center of metropolitan areas. As a result, to solve the long term problem of housing shortage and ensure the right to housing, the government should create a coordinated set of regulatory measures for the housing policy. These policies should aimed not only housing construction, as well as control of the rent prices, to reduce the excessive burden on housing, and create of a social tax on vacant dwellings, to curb property speculation.

  5. Apertura comercial y desarrollo económico mundial en la globalización

    Carlos Encinas Ferrer

    2012-01-01

    Full Text Available La política económica neoliberal ha promovido a escala global la apertura comercial bajo la hipótesis de que la liberalización del comercio da lugar automáticamente a un quiebre positivo en la tendencia de crecimiento económico. Esta acción de política económica está sustentada fundamentalmente en la teoría de la ventaja comparativa desarrollada por David Ricardo en la segunda década del Siglo XIX. Sin embargo, la ausencia de un incremento generalizado del PIB que acompañe la apertura comercial implementada a partir de la década de los ochenta en una gran cantidad de países nos muestra señales de que algo ha sucedido en el modelo exportador adoptado contrario a las expectativas favorables prometidas. México y muchos otros países se encuentran en un callejón sin salida, con problemas que se han profundizado con la reciente crisis económica que hasta ahora, especialmente en EE.UU. y Europa, no muestra señales de una recuperación global.

    Full Text Available This study aims to examine the treatment of linguistic variation in Brazilian Portuguese textbooks for High School and prompts a debate about concepts like right and wrong, language variation, language change and language prejudice. In this sense, it considers whether the textbook discusses the linguistic variation, understanding it as a result of a variety of sociocultural factors of a linguistic community. Our corpus consists of a collection of Portuguese Language for High School, prepared by Carlos Alberto Faraco, approved by the National Textbook Program (PNLD 2015. The research is part of the dialogue between Sociolinguistics and mother tongue teaching, more specifically, in theoretical and methodological studies of Bortoni-Ricardo (2004, Faraco (2004, Alkmim (2005, Labov (2008, among others, in addition to the National Curriculum Parameters of High School Portuguese Language – PCN (BRASIL, 2000. The methodology is based on descriptive, bibliographical and documentary research and a qualitative approach. The results show, that the current development, in that collection highlights a concern to incorporate linguistic studies in the heterogeneity and linguistic diversity from sociolinguistic perspective.

  7. Sensitivity of dual fuel engine combustion and knocking limits to gaseous fuel composition

    Selim, Mohamed Y.E.

    2004-01-01

    Combustion noise, knock and ignition limits data are measured and presented for a dual fuel engine running on dual fuels of Diesel and three gaseous fuels separately. The gaseous fuels used are liquefied petroleum gas, pure methane and compressed natural gas mixture. The maximum pressure rise rate during combustion is presented as a measure of combustion noise, and the knocking and ignition limits are presented as torque output at the onset of knocking and ignition failure. Experimental investigation on the dual fuel engine revealed the noise generated from combustion, knocking and ignition limits for all gases at different design and operating conditions. A Ricardo E6 Diesel version engine is converted to run on dual fuel of Diesel and the tested gaseous fuel and is used throughout the work. The engine is fully computerized, and the cylinder pressure data, crank angle data and engine operating variables are stored in a PC for off line analysis. The effects of engine speeds, loads, pilot injection angle, pilot fuel quantity and compression ratio on combustion noise, knocking torque, thermal efficiency and maximum pressure are examined for the dual engine running on the three gaseous fuels separately. The combustion noise, knocking and ignition limits are found to relate to the type of gaseous fuels and to the engine design and operating parameters

  8. The central bank issuing policy and Fisher´s equation of exchange

    Richard Pospíšil

    2013-05-01

    Full Text Available The issue of money and establishing interest rates are the main activities of central banks. Through this, the banks immediately influence the behaviour of households, companies, financial markets and the state with the impact on real outcome, employment and prices. When monitoring the issue of money, it is necessary to focus not only on its volume, but also on the attributes and functions carried by money. Among the first economists who considered the quality monetary aspect were J. Locke, D. Hume, D. Ricardo and others. The founders of modern monetarism of the 20th century were I. Fisher and M. Friedman. Fisher was the first to define the equation of monetary equilibrium in the present-day form. The objective of the paper is to point out different approaches to the equation and its modifications and different meanings of its variables. As regards the monetary aggregate M – Money – the paper also deals with the denomination of the aggregate to its various elements, which is significant for fulfilling monetary policy targets. This approach is very important especially at present in the time of crisis when central banks are performing their policy considering contradictory targets of price stability and economic growth.

  10. Chagas. From Exotic Tropical Disease to Pathology Globalized

    Beatriz BASSO

    2016-09-01

    Full Text Available Chagas disease, whose aetiological agent is Trypanosoma cruzi, is one of the main endemic diseases in Latin America, ranking fourth regarding the number of lost life years due to death or disability in the area; nevertheless, it is among the so-called “neglected diseases”. Despite its rural origin, where it is transmitted through vector insects belonging to the Reduviidae family, it has nowadays also become a problem in urbanized areas and is becoming globalized through inter-human transmission, above all congenital, but also through transfusions and transplants. Chagas, a Hidden Affliction (Chagas, Un mal escondido, a documentary by Ricardo Preve, focuses on both aspects of the disease: the rural and the global one, including interviews with North American doctors and European researchers. A significant part of the film takes place in the USA, showing the worst consequence of the evolution of the disease, which is death by chagasic cardiopathy which, being a reality that takes place during filming, increases the sense of drama. In this paper we approach specific topics related to Chagas disease from a biomedical point of view, including comments related to the highlights of the film that are connected with such aspects. Towards the end, there is mention of the film Houses of Fire (Casas de fuego and of certain illustrative aspects concerning the life of Dr Salvador Mazza and the Argentine Mission of Regional Pathology Studies (MEPRA, topics that have already been dealt with in this.

    In summer, temperatures in cities may rise, thereby inducing the so-called 'urban heat island' and tremendous consequences on outdoor comfort, health risks, pollutant emission and energy consumption. Replacing vegetation and moist surfaces by concrete or asphalt may enhance these problems. Therefore, the aim of this thesis is to quantify the impact of vegetation and water on urban micro-climate and comfort through numerical modelling; In the first part, a scientific literature review considers various topics applied to our problem such as urban micro-climate, simulations, urbanism, urban forestry and outdoor thermal comfort. This information is relevant to define and interpret further numerical modelling. Numerical simulations based on the coupling of the SOLENE. thermal program and the N3S CFD code are proposed to model wind flow, air and surface temperatures. The theoretical principles, hypothesis and coupling methodology are presented here. This set of numerical tools is combined in order to help urban or landscape planners, architects and engineers, to analyse the impacts of different projects on micro-climate and on outdoor thermal comfort, under hot summer conditions. To illustrate this approach, an open space in Montpellier (southern France) called the 'Place du Millenaire' and designed by Ricardo Bofill is studied, considering various cases (no vegetation, actual vegetation and vegetation in 30 years). The comparative results demonstrate improvements of urban form, micro-climate and outdoor thermal comfort. (author)

    The Passagem granite includes stocks, plugs and dikes located in the Ricardo Franco hill - Vila Bela da Santissima Trindade region - state of Mato Grosso, central Brazil. The Passagem Granite is included in the Paragua terrane - SW Amazonian Craton. It consists of isotropic monzogranite, sienogranite and more rarely granodiorites with leucocratic dark gray to white color. These rocks range from hypidomorphic inequigranular to xenomorphic texture, fine to medium grained. Biotite is the only primary mafic present as essential phase and characterize an expanded slightly acid sequence formed by a sub-alkaline magmatism of high-potassium calc-alkaline, slightly peraluminous composition from arc magmatic tectonic environment during a post-collisional period. Mechanism of fractional crystallization of plagioclase, biotite, titanite, apatite and zircon associated with simultaneous crustal assimilation are suggested for the evolution of these rocks. The results support the hypothesis of a post-collisional magmatism in the Paragua terrane at 1284 +- 20 Ma corresponding to the crystallization age of the Passagem granite. This paper propose that Passagem Granite represents as an extension in Brazilian terrane of the Pensamiento Granitoid Complex. (author)

    2010-01-01

    An experimental investigation is conducted to evaluate the effects of using blends of n-butanol (normal butanol) with conventional diesel fuel, with 8%, 16% and 24% (by volume) n-butanol, on the performance and exhaust emissions of a standard, fully instrumented, four-stroke, high-speed, direct injection (DI), Ricardo/Cussons 'Hydra' diesel engine located at the authors' laboratory. The tests are conducted using each of the above fuel blends or neat diesel fuel, with the engine working at a speed of 2000 rpm and at three different loads. In each test, fuel consumption, exhaust smokiness and exhaust regulated gas emissions such as nitrogen oxides, carbon monoxide and total unburned hydrocarbons are measured. The differences in the measured performance and exhaust emission parameters of the three butanol-diesel fuel blends from the baseline operation of the diesel engine, i.e., when working with neat diesel fuel, are determined and compared. It is revealed that this fuel, which can be produced from biomass (bio-butanol), forms a challenging and promising bio-fuel for diesel engines. The differing physical and chemical properties of butanol against those for the diesel fuel are used to aid the correct interpretation of the observed engine behavior.

    Full Text Available Este artículo explora las relaciones entre paisaje, identidad y cultura popular en algunas obras de Ricardo Rojas, Bernardo Canal Feijóo y Orestes Di Lullo sobre Santiago del Estero. Consideramos que Canal Feijóo y Di Lullo regresaron en sus trabajos de las décadas de 1930 y 1940 a tres cuestiones tratadas por Rojas en El país de la selva (1907, aunque en un contexto ya irremediablemente cambiado de destrucción del bosque chaqueño. La primera de ellas consiste en la búsqueda de los orígenes de la cultura folclórica santiagueña en el período colonial. En ausencia de flujos consistentes de inmigración europea, los autores se remitieron a la conquista y a los mestizajes biológicos y culturales posteriores como punto de partida para la formación de una cultura local que ambos estimaban aún vigorosa y original. La segunda es la identidad entre paisaje y cultura folclórica. Di Lullo y Canal compartían con Rojas la idea de que la imaginación popular nacía de la naturaleza o, mejor dicho, de la sensibilidad de sujetos íntimamente consustanciados con ella. En consecuencia, la destrucción del paisaje sólo podía conducir a la del folclore, al que encontraban ya irremediablemente degradado. En tercer lugar, se hallaba la elevación del folclore santiagueño a marca de origen, a sello identitario. El componente indígena, hispano o mestizo se encontraba presente, en diferentes medidas, en aquel patrimonio ancestral que, como Rojas lo había hecho antes, Canal y Di Lullo describieron e interpretaron a la luz de sus personales lecturas de la historia santiagueña.This article explores the relationship between landscape, identity and popular culture of Santiago del Estero in the works of Ricardo Rojas, Bernardo Canal Feijóo and Orestes Di Lullo.

Este estudo teve por objetivo conhecer as atitudes preventivas e curativas do cuidado proporcionado pelos monitores educacionais dos Centros Municipais Educacionais Infantis da Cidade de Cascavel - PR diante das IRA. Para tanto, realizamos entre novembro a dezembro de 2008, uma pesquisa qualitativa com 12 monitores educacionais, por meio da entrevista semi-estruturada gravada. Os aspectos emergentes das entrevistas foram pontuados e orientado na ótica do cuidado integral de José Ricardo de Carvalho Mesquita Ayres. As ações das monitoras educacionais em relação as IRA têm caráter curativo, sendo fundamentadas no cuidado técnico e entendimentos causais. Nessas ações faltam elementos que compõem o cuidado integral como o movimento, a interação, a reconstrução de identidades e alteridades, a não-causalidade, a plasticidade, a temporalidade e a responsabilidade. Diante disso, enfatiza-se a necessidade de preparar os monitores e as instituições para o cuidado integral. E, sobretudo, a articulação dos centros educacionais aos setores de saúde promovendo a aplicação de estratégias para o controle, prevenção e promoção da saúde das crianças.Acute respiratory infections are the causes of morbidity and mortality during infancy and childhood.

    Full Text Available The air hybrid engine absorbs the vehicle kinetic energy during braking, stores it in an air tank in the form of compressed air, and reuses it to propel a vehicle during cruising and acceleration. Capturing, storing and reusing this braking energy to give additional power can therefore improve fuel economy, particularly in cities and urban areas where the traffic conditions involve many stops and starts. In order to reuse the residual kinetic energy, the vehicle operation consists of 3 basic modes, i.e. Compression Mode (CM, Expander Mode (EM and normal firing mode. Unlike previous works, a low cost air hybrid engine has been proposed and studied. The hybrid engine operation can be realized by means of production technologies, such as VVT and valve deactivation. In this work, systematic investigation has been carried out on the performance of the hybrid engine concept through detailed gas dynamic modelling using Ricardo WAVE software. Valve timing optimization has been done for the more efficient operation of air hybrid operation and obtaining higher braking and motoring mean effective pressure for CM and EM respectively. Le moteur hybride à air absorbe l’énergie cinétique du véhicule en cas de freinage, la stocke sous forme d’air comprimé, puis la réutilise pour faire avancer le véhicule en circulation ou en accélération. Capter, stocker et réutiliser cette énergie et créer ainsi une puissance plus importante peut donc permettre de plus grandes économies de carburant, surtout en ville et zone urbaine, lorsque les conditions de circulation imposent de nombreux arrêts et démarrages. Pour pouvoir réutiliser l’énergie cinétique, on distingue trois modes de base d’utilisation du véhicule : les modes compression (MC, expansion (ME et standard. Un moteur hybride à air et à bas prix a été proposé et étudié. Un tel moteur peut être opéré par le biais de technologies de production, comme le VVT et la d

His ability to prepare students for participation in a form of media communication led to the fusion of educational, cultural and social elements that facilitated a dialog between the students and the world. The purpose was not to prepare a student publication for the educational center, but rather to publish in the daily newspaper. The children expressed themselves freely on diverse topics and themes at a time in which the Franco dictatorship represented definite censorship. Initially the work came out of the professional work of the aforementioned teacher, in a school in the town of La Zarza, in the municipality of Arico (south of the island of Tenerife, that discovered the ability to narrate, describe, interpret and retell the activities of his students that he felt worthy of notice.

    2016-01-01

    The International Workshop on Nonlinear Maps and their Applications (NOMA) is a series of international conferences. NOMA editions were held in Toulouse (Noma’07), Urbino (Noma’09), Évora (Noma’ 11) and Zaragoza (Noma’13). The fifth edition of NOMA was organised and hosted by the School of Electrical and Electronic Engineering of University College Dublin. This workshop brings together researchers from theoretical and application areas (mathematics, physics, engineering and economics) who study nonlinear discrete systems. Nonlinear iterative processes play an important role in physical, biological and social phenomena. Nonlinear mappings can directly model various systems or can be obtained using numerical methods permitting the solution of differential nonlinear equations. In both cases, the understanding of specific behaviours and bifurcations of these type of systems is of the greatest interest. This workshop is open to theoretical studies as well as applicative ones in the fields of physics, electronics, biology, computational methods, engineering, telecommunications and others. The scientific programme of NOMA’ 15 included 28 invited and regular lectures with 12 selected talks published in this special issue. Prof Vassili Gelfreich (the University of Warwick), Prof Daniele Fournier-Prunaret (INSA Toulouse), Prof Ricardo Lopez-Ruiz (the University of Zaragoza), Prof Sergio Callegari (the University of Bologna), Prof Yoshifumi Nishio (Tokushima University) and Dr Elena Blokhina (University College Dublin) have served as the editors of NOMA’2015 and selected the papers.

  10. Summary of the analyses for recovery factors

    Verma, Mahendra K.

    2017-07-17

    IntroductionIn order to determine the hydrocarbon potential of oil reservoirs within the U.S. sedimentary basins for which the carbon dioxide enhanced oil recovery (CO2-EOR) process has been considered suitable, the CO2 Prophet model was chosen by the U.S. Geological Survey (USGS) to be the primary source for estimating recovery-factor values for individual reservoirs. The choice was made because of the model’s reliability and the ease with which it can be used to assess a large number of reservoirs. The other two approaches—the empirical decline curve analysis (DCA) method and a review of published literature on CO2-EOR projects—were deployed to verify the results of the CO2 Prophet model. This chapter discusses the results from CO2 Prophet (chapter B, by Emil D. Attanasi, this report) and compares them with results from decline curve analysis (chapter C, by Hossein Jahediesfanjani) and those reported in the literature for selected reservoirs with adequate data for analyses (chapter D, by Ricardo A. Olea).To estimate the technically recoverable hydrocarbon potential for oil reservoirs where CO2-EOR has been applied, two of the three approaches—CO2 Prophet modeling and DCA—do not include analysis of economic factors, while the third approach—review of published literature—implicitly includes economics. For selected reservoirs, DCA has provided estimates of the technically recoverable hydrocarbon volumes, which, in combination with calculated amounts of original oil in place (OOIP), helped establish incremental CO2-EOR recovery factors for individual reservoirs.The review of published technical papers and reports has provided substantial information on recovery factors for 70 CO2-EOR projects that are either commercially profitable or classified as pilot tests. When comparing the results, it is important to bear in mind the differences and limitations of these three approaches.

  12. Biological trade and markets.

    Hammerstein, Peter; Noë, Ronald

    2016-02-05

    Cooperation between organisms can often be understood, like trade between merchants, as a mutually beneficial exchange of services, resources or other 'commodities'. Mutual benefits alone, however, are not sufficient to explain the evolution of trade-based cooperation. First, organisms may reject a particular trade if another partner offers a better deal. Second, while human trade often entails binding contracts, non-human trade requires unwritten 'terms of contract' that 'self-stabilize' trade and prevent cheating even if all traders strive to maximize fitness. Whenever trading partners can be chosen, market-like situations arise in nature that biologists studying cooperation need to account for. The mere possibility of exerting partner choice stabilizes many forms of otherwise cheatable trade, induces competition, facilitates the evolution of specialization and often leads to intricate forms of cooperation. We discuss selected examples to illustrate these general points and review basic conceptual approaches that are important in the theory of biological trade and markets. Comparing these approaches with theory in economics, it turns out that conventional models-often called 'Walrasian' markets-are of limited relevance to biology. In contrast, early approaches to trade and markets, as found in the works of Ricardo and Cournot, contain elements of thought that have inspired useful models in biology. For example, the concept of comparative advantage has biological applications in trade, signalling and ecological competition. We also see convergence between post-Walrasian economics and biological markets. For example, both economists and biologists are studying 'principal-agent' problems with principals offering jobs to agents without being sure that the agents will do a proper job. Finally, we show that mating markets have many peculiarities not shared with conventional economic markets. Ideas from economics are useful for biologists studying cooperation but need

    Highlights: • Waste heat recovery on internal combustion engines is studied. • The backpressure effect of the Organic Rankine Cycle boiler has been evaluated. • Three different state-of-the art turbocharging technologies have been assessed. • Six different fluids for medium-high temperature recovery have been considered. • A reduction up to 10% in fuel consumption can be achieved. - Abstract: In marine and power generation sectors, waste heat recovery technologies are attracting growing attention in order to increase heavy duty diesel engines efficiency and decrease fuel consumption, with the purpose of respecting stringent emissions legislations. In this work, the backpressure effect of an Organic Rankine Cycle (ORC) evaporator on the exhaust line of a turbocharged, V12 heavy duty diesel engine, for typical marine and power generation applications has been investigated using the commercial software Ricardo WAVE. Three different state-of-the art turbocharging strategies are assessed in order to counterbalance the increased pumping losses of the engine due to the boiler installation: fixed turbine, Waste-Gate (WG) and Variable Geometry Turbine (VGT). At the same time, the steady-state thermodynamic performance of two different ORC configurations, simple tail-pipe evaporator and recuperated simple tail-pipe evaporator layouts, are assessed, with the scope of further increasing the engine power output, recovering unutilized exhaust gas heat. Several different working fluids, suitable for medium-high temperature waste heat recovery, are evaluated and screened, considering, as well, health and safety issues. Thermodynamic cycle parameters such as, for example, evaporation and condensing pressures, working fluid mass flow and cycle temperatures, are optimized in order to obtain the maximum improvement in Brake Specific Fuel Consumption (bsfc). From the engine side point of view, a VGT turbocharger is the most favorable solution to withstand increased

  14. The somatic marker theory in the context of addiction: contributions to understanding development and maintenance

    Full Text Available Vegard V Olsen,1 Ricardo G Lugo,1 Stefan Sütterlin1,2 1Section of Psychology, Lillehammer University College, Lillehammer, 2Department of Psychosomatic Medicine, Division of Surgery and Clinical Neuroscience, Oslo University Hospital – Rikshospitalet, Oslo, Norway Abstract: Recent theoretical accounts of addiction have acknowledged that addiction to substances and behaviors share inherent similarities (eg, insensitivity to future consequences and self-regulatory deficits. This recognition is corroborated by inquiries into the neurobiological correlates of addiction, which has indicated that different manifestations of addictive pathology share common neural mechanisms. This review of the literature will explore the feasibility of the somatic marker hypothesis as a unifying explanatory framework of the decision-making deficits that are believed to be involved in addiction development and maintenance. The somatic marker hypothesis provides a neuroanatomical and cognitive framework of decision making, which posits that decisional processes are biased toward long-term prospects by emotional marker signals engendered by a neuronal architecture comprising both cortical and subcortical circuits. Addicts display markedly impulsive and compulsive behavioral patterns that might be understood as manifestations of decision-making processes that fail to take into account the long-term consequences of actions. Evidence demonstrates that substance dependence, pathological gambling, and Internet addiction are characterized by structural and functional abnormalities in neural regions, as outlined by the somatic marker hypothesis. Furthermore, both substance dependents and behavioral addicts show similar impairments on a measure of decision making that is sensitive to somatic marker functioning. The decision-making deficits that characterize addiction might exist a priori to addiction development; however, they may be worsened by ingestion of substances with

Estrogen preparations provide the most effective treatment; local application is preferred to systemic drugs when treating only vaginal symptoms.

    To describe the clinical and endoscopic caracteristics of a population that has only serrated polyps of colon (mainly sessile serrated adenomas) in a private clinic in Lima, Perú, from 2009-2011. Retrospective study conducted at the endoscopy center of Clinic Ricardo Palma, Lima, Peru. Olympus colonoscope was used with high definition, including NBI (narrow band imaging) and electronic magnification. Patients had pathologic diagnosis of “polyps and / or colorectal serrated adenomas” and excluded those with synchronous tubular or villous adenomas. Images were evaluated by two endoscopists and then by a third gastroenterologist. We found 201 serrated polyps in 108 patients. Women were 60.2% and overweight predominated. Eighty (74.1%) had only one serrated adenoma and 23 (21.3%) with at least one synchronous hyperplastic polyp. The average size of sessile serrated adenomas was 5.12 mm (± 3.87 DS) and the flat type was 91 (58.7%). There were significant differences in the diameter of sessile serrated adenomas between the distal and proximal colon (4.47 mm ± 2.23 vs. 6.90 mm ± 6.25; p<0.000). The common features of sessile serrated adenomas were: White (31/36, 86.1%), smooth (28/36, 77.8%) and regular margins (26/36, 72.2%). There was a relationship between vascular pattern according NBI and serrated polyp histology (p=0.024). The endoscopic features of sessile serrated adenomas can evade detection to white light. NBI is a useful tool to define some features of these lesions.

    2009-07-01

    Flywheel based mechanical hybrid technology is being developed for both motorsport and mainstream automotive applications. One particular road car application project, part funded by the UK Government Technology Strategy Board, is being led by Jaguar Land Rover, managed by Prodrive and using advanced technology from Flybrid Systems, Ford, Ricardo. Torotrak and Xtrac. During the two year programme, the group will develop the new technology and build a demonstrator vehicle equipped with the system. The mechanical system recovers kinetic energy from the vehicle during braking to a high speed rotating flywheel via a variable drive system. When compared to an electric motor / battery arrangement, the mechanical hybrid system offers benefits in cost, weight, package, efficiency and ultimately vehicle fuel consumption. As part of the development and optimisation process in order to specify the road car system, all aspects of the mechanical hybrid system are under investigation by the group. Alongside the required quantity of energy storage and the rates of energy recovery and reapplication, a number of different physical architectures for the system are being analysed. The Torotrak full-toroidal traction drive has been assigned as the variable drive element of the mechanical hybrid system. Multiple configuration options are available including direct drive, epicyclic shunted, range extended CVT and epicyclic shunted IVT arrangements. In addition, the flywheel and variable drive system can be connected to the powertrain in a variety of different locations, from the engine through the powertrain to the wheels. This paper describes the simulation of the mechanical hybrid system with particular focus on the impact on the fuel consumption benefit, over multiple drive cycles, of the variable drive configuration, the location of the variable drive and flywheel system and the control strategy options.

    Highlights: • The effect of using variable LPG is studied. • Five fuels with propane to butane % volume ratio are: 100-70-55-25-0. • 100% Propane composition shows the highest noise levels with similar performance. • At 45° BTDC injection timing 55% Propane LPG the only fuel experience knocking. • LPG fuels gave similar engine performance, with differences in levels of noise. - Abstract: The present work investigates experimentally the effect of LPG fuel with different composition and engine parameters on the performance of a dual compression engine. Five different blends of LPG fuels are used with Propane to Butane volume ratio of 100:0, 70:30, 55:45, 25:75, and 0:100. A single cylinder, naturally aspirated, four strokes, indirectly injected, water cooled modified Ricardo E6 engine, is used in this study. The study is carried out by measuring the cylinder pressure, engine load, engine speed, crank angle, and the fuel’s flow rate. The engine performance under variable LPG fuel composition, engine load, pilot fuel injection timing, compression ratio, pilot fuel mass and engine speed, are estimated by comparing the following engine parameters: the cylinder maximum pressure, the indicated mean effective pressure, the maximum rate of pressure rise, and the thermal efficiency. The experimental data indicates that the engine parameters are playing a major role on the engine’s performance. Different LPG fuel composition did not show a major effect on the engine efficiency but directly impacted the levels of generated combustion noise

Mayaro virus (MAYV is classified in the Semliki Forest virus antigenic complex and shares similarities with the alphavirus Chikungunya virus and the flavivirus Dengue virus. MAYV is an arbovirus transmitted by Haemagogus janthinomys, with competence also demonstrated in Aedes aegypti, Aedes scapularis, and Anopheles quadrimaculatus. Outbreaks and small epidemics of Mayaro fever have occurred in several countries in northern South America and the Caribbean. In addition, travel-associated cases have been reported in European nationals returning from endemic areas. Clinical features of Mayaro fever include fever, chills, persistent arthralgia, retro-orbital pain, maculopapular rash, itching, dizziness, and, rarely, lymphadenopathy. Methods of control for MAYV are similar to those used for other sylvatic arboviruses. Although MAYV was discovered as long ago as the 1950s and continues to be prevalent in the tropical areas of the Americas, it remains neglected and under-studied. This paper provides a thorough and current review of the published MAYV literature ranging from its original description to modern outbreaks, and from the basic virus characteristics to the clinical and epidemiological aspects of this disease. Keywords: Mayaro virus, emerging arbovirus, dengue-like virus, arthrogenic virus

    Full Text Available El presente estudio escoje un período de gran envergadura teológica y excepcionalmente sensible al problema razón y amor. En el siglo XII se va gestando la subjetividad moderna, de tanta relevancia para la Teología, pero, sobre todo, se produce aquella confluencia de fuentes latinas y griegas, que como problema requiere máxima atención, ya que su recepción patrística medieval es vital para la búsqueda de la verdad a través de la ciencia. Se estudian siete autores que remontan al siglo XII: -Hildegard von Bingen, Guillermo de St. Thierry, Ricardo de San Víctor-, pero tres le preceden: -Gregorio Magno, Juan Escoto Eriúgena, Anselmo de Canterbury- y uno los complementa: Buenaventura. La elección de estos autores ha permitido seguir de cerca la articulación del problema, su contextualización y las soluciones novedosas, de gran riqueza antropológica teológicaThis study selects a period of great theological depth and particularty sensitive to the issue of reason and love. The modern subjectivity, which has had enormous relevance for Theology, started to germinate during the XII century; the times of the convergence of the Latin and Greek sources. This required much attention, as their reception by the medieval patristic is essential for a proper search of the truth through the science. The article focuses on seven authors who date from the XII century. Hildegard von Binger, Willian of St. Thierry, Richard of Saint Victor, who are preceded by Gregory the Greta, John Scotus Eriungena, Anselm of Canterbury and Bonaventure. The selecction of these authors allows a close articulation of the problem, its contextualisation and novel solutions of great theological and anthropological richness

We verified the preventive effects of Ex on lung oxidative markers induced by smoking. In this study, 36 mice (C57BL-6, 30–35 g were split into four groups: control, CS, Ex, and CS plus Ex. Ex groups were given prior physical training in water (2×30 min/d, 5 days/wk, 8 weeks. After training, the CS groups were subjected to passive exposure to four cigarettes, 3 × per day, for 60 consecutive days. After 24 hours from the last exposure, CS animals were sacrificed, and lung samples were collected for further analysis. Left lung sample was prepared for histological analysis, and right lung was used for biochemical analysis (superoxide, hydroxyproline, lipid peroxidation [thiobarbituric acid reactive species], protein carbonylation [carbonyl groups formation], superoxide dismutase [SOD], catalase [CAT], and glutathione peroxidase [GPx] activities. Group comparisons were evaluated by analysis of variance (ANOVA. Results were expressed as mean ± standard deviation, with P<0.05 considered significantly different. Preventive Ex impeded histological changes and increased the enzymatic defense system (SOD and GPx by reducing oxidative damage in lipids and proteins. This preventive effect of prior physical Ex alleviates damage caused by CS exposure.Keywords: exercise

  4. Empujados hacia la muerte. Guiones trágicos para los hombres que aman a otros hombres.

    2011-07-01

    Full Text Available Pensadores como Michel Foucault,  Judith Butler o Ricardo Llamas, han llamado la atención acerca de la estrecha relación que se establece en la cultura occidental entre la homosexualidad y la muerte, lo cual se manifiesta en sus creaciones culturales. Otro rasgo que caracteriza la politica sexual predominante es la desvirtuación de la bisexualidad originaria del ser humano, a través del establecimiento de dos categorías excluyentes: homosexual y heterosexual. Con objeto de verificar cómo todo ello se refleja en nuestros discursos cinematográficos se ha escogido un corpus amplio de películas  europeas y norteamericanas, de todas las épocas, que incluyen en su relato un evento específico: el de la muerte de uno o varios personajes que mantienen relaciones sexuales con personas de su mismo sexo. Se han detectado varias líneas narrativas que se repiten, de las cuales se han incluido aquí ejemplos de las siguientes: la perplejidad el hombre ante su propia ambivalencia sexual y su trágico destino cuando infringe la norma heterosexista; la muerte social, el suicidio y las conductas autodestructivas; la ejecución del sodomita; el asesinato del homosexual como resultado del clima de homofobia, la muerte del homosexual malvado; la eliminación del intruso en la relación heterosexual. Se concluye que, efectivamente, el cine es un agente activo en la difusión de narrativas que asocian estrechamente la homosexualidad con la muerte.

This study aims to investigate the impact of limbic system morphology on FER scores in BD subjects and healthy controls.Material and methods: Thirty-nine euthymic BD I (type I subjects and 40 healthy controls were subjected to a battery of FER tests and examined with 3D structural imaging of the amygdala and hippocampus.Results: The volume of these structures demonstrated a differential pattern of influence on FER scores in BD subjects and controls. In our control sample, larger left and right amygdala demonstrated to be associated to less recognition of sadness faces. In BD group, there was no impact of amygdala volume on FER but we observed a negative impact of the left hippocampus volume in the recognition of happiness while the right hippocampus volume positively impacted on the scores of happiness.Conclusion: Our results indicate that amygdala and hippocampus volumes have distinct effects on FER in BD subjects compared to controls. Knowledge of the neurobiological basis of the illness may help to provide further insights on the role of treatments and psychosocial interventions for BD. Further studies should explore how these effects of amygdala and hippocampus volumes on FER are associated with social networks and social network functioning.Keywords: bipolar disorder, social cognition, facial emotion recognition

  6. Effects of piston surface treatments on performance and emissions of a methanol-fueled, direct injection, stratified charge engine

    West, B.; Green, J.B. [Oak Ridge National Lab., TN (United States)

    1994-07-01

    The purpose of this study was to investigate the effects of thermal barrier coatings and/or surface treatments on the performance and emissions of a methanol-fueled, direct-injection, stratified-charge (DISC) engine. A Ricardo Hydra Mark III engine was used for this work and in previous experiments at Oak Ridge National Laboratory (ORNL). The primary focus of the study was to examine the effects of various piston insert surface treatments on hydrocarbon (HC) and oxides of nitrogen (NO{sub x}) emissions. Previous studies have shown that engines of this class have a tendency to perform poorly at low loads and have high unburned fuel emissions. A blank aluminum piston was modified to employ removable piston bowl inserts. Four different inserts were tested in the experiment: aluminum, stainless steel with a 1.27-mm (0.050-in.) air gap (to act as a thermal barrier), and two stainless steel/air-gap inserts with coatings. Two stainless steel inserts were dimensionally modified to account for the coating thickness (1.27-mm) and coated identically with partially stabilized zirconia (PSZ). One of the coated inserts then had an additional seal-coat applied. The coated inserts were otherwise identical to the stainless steel/air-gap insert (i.e., they employed the same 1.27-mm air gap). Thermal barrier coatings were employed in an attempt to increase combustion chamber surface temperatures, thereby reducing wall quenching and promoting more complete combustion of the fuel in the quench zone. The seal-coat was applied to the zirconia to reduce the surface porosity; previous research suggested that despite the possibly higher surface temperatures obtainable with a ceramic coating, the high surface area of a plasma-sprayed coating may actually allow fuel to adhere to the surface and increase the unburned fuel emissions and fuel consumption.

Methods: Thirty-three participants from the Argentina-Alzheimer’s Disease Neuroimaging Initiative database completed a cognitive battery, the Cognitive Reserve Questionnaire (CRQ, and an Argentinian accentuation reading test (TAP-BA as a measure of premorbid intelligence, and underwent lumbar puncture for CSF biomarker quantification. Results: The CRQ significantly correlated with TAP-BA, education, and Aβ1-42. When considering Aβ1-42 levels, significant differences were found in CRQ scores; higher levels of CSF Aβ1-42 were associated with higher CRQ scores. Conclusion: Reduced Aβ1-42 in CSF is considered as evidence of amyloid deposition in the brain. Previous results suggest that individuals with higher education, higher occupational attainment, and participation in leisure activities (cognitive reserve have a reduced risk of developing Alzheimer’s disease. Our results support the notion that enhanced neural activity has a protective role in mild cognitive impairment, as evidenced by higher CSF Aβ1-42 levels in individuals with more cognitive reserve.

  9. [History from neuropsychology to cognitive neurosciences in Argentina].

    Allegri, Ricardo F; Bagnatti, Pablo

    2017-11-01

    The first step from the neuropsychology in Argentina was in 1883 with the thesis of Antonio Piñeiro about the brain localization of the language and vision disorders, only few years after Broca. The aim of this work has been to describe the development of the neuropsychology in Argentina and its relation with the psychology, neurology and psychiatry. The first period was into the neurology with its French school in?uence. In 1907, Jose Ingeniero published in French his book about "amusia", Cristofredo Jakob the "folia neurobiologica" where he described the organization of the human brain, Vicente Dimitri in 1933 his book "aphasia" and Bernardo de Quiros in 1959 his works about dyslexia. The psychiatry at the hospices with the German influence from Jakob developed to the modern neuropsychiatry with Juan Carlos Goldar. The argentine school of psychology by the holism and the psychoanalysis influence do not accept the neuropsychology until 1960 where was included at the school of psychology from the university of Buenos Aires (UBA) with the first linguistics works of Juan Azcoaga. At the 80, began the North American influence of the neurology with authors like Carlos Mangone (dementia), Ramon Leiguarda (apraxia), Sergio Starkstein (depression and apathy) and Ricardo Allegri (memory and Alzheimer). In 1982 the Argentine Neuropsychological Society was founded and in 1987 was the working group of dementia from the Argentine Neurological Society. At this moment, Aldo Ferreres organized the chair of neuropsychology at the school of psychology (UBA). Nowadays, the growing as discipline is in context of the psychology, neurology and psychiatry in the way of the recent cognitive neurosciences.

We assessed the patients' quality of life through the Brazilian 25-question version of the National Eye Institute Visual Functioning Questionnaire, comprising 12 subscales (general health, general vision, ocular pain, near vision, distance vision, social function, mental health, role limitations, dependency, driving, color vision, and peripheral vision and a total composite score. Clinical features, including current medical treatment, were obtained from each patient's medical record. Three groups of patients were identified according to the prostaglandin in use: bimatoprost, latanoprost, or travoprost. The main outcome measures were: mean score in each subscale and mean total composite score.Results: The mean total composite score for the whole group was 70.60. The bimatoprost, latanoprost, and travoprost groups had the following mean composite scores, respectively: 56.56, 77.36, and 71.08 (P = 0.001, analysis of variance [ANOVA]. Latanoprost and travoprost results were similar, and both were superior to bimatoprost. Most subscales had similar results. The subscale with the lowest score for all groups was general health. Groups were homogenous and comparable.Conclusion: There is a difference in the quality of life between glaucoma patients using prostaglandin analogs. It seems that bimatoprost users have lower QoL when compared to latanoprost and travoprost users.Keywords: glaucoma, medical treatment, prostaglandin analogs

  11. From Ecology to Finance (and Back?): A Review on Entropy-Based Null Models for the Analysis of Bipartite Networks

    Straka, Mika J.; Caldarelli, Guido; Squartini, Tiziano; Saracco, Fabio

    2018-04-01

    Bipartite networks provide an insightful representation of many systems, ranging from mutualistic networks of species interactions to investment networks in finance. The analyses of their topological structures have revealed the ubiquitous presence of properties which seem to characterize many—apparently different—systems. Nestedness, for example, has been observed in biological plant-pollinator as well as in country-product exportation networks. Due to the interdisciplinary character of complex networks, tools developed in one field, for example ecology, can greatly enrich other areas of research, such as economy and finance, and vice versa. With this in mind, we briefly review several entropy-based bipartite null models that have been recently proposed and discuss their application to real-world systems. The focus on these models is motivated by the fact that they show three very desirable features: analytical character, general applicability, and versatility. In this respect, entropy-based methods have been proven to perform satisfactorily both in providing benchmarks for testing evidence-based null hypotheses and in reconstructing unknown network configurations from partial information. Furthermore, entropy-based models have been successfully employed to analyze ecological as well as economic systems. As an example, the application of entropy-based null models has detected early-warning signals, both in economic and financial systems, of the 2007-2008 world crisis. Moreover, they have revealed a statistically-significant export specialization phenomenon of country export baskets in international trade, a result that seems to reconcile Ricardo's hypothesis in classical economics with recent findings on the (empirical) diversification industrial production at the national level. Finally, these null models have shown that the information contained in the nestedness is already accounted for by the degree sequence of the corresponding graphs.

Lipid nanoparticles, specifically nanostructured lipid carriers (NLC, were synthetized by the high-shear homogenization and ultrasonication techniques. These nanoparticles were designed to exhibit both passive and active targeting strategies to be efficiently internalized by the alveolar macrophages, traffic to the acidified phagosomes and phagolysosomes, and release bactericidal concentrations of the antituberculosis drug intracellularly. NLC that could entrap RFB were prepared, characterized, and further functionalized with mannose. Particles’ diameter, zeta potential, morphology, drug% entrapping efficiency, and drug release kinetics were evaluated. The mannose coating process was confirmed by Fourier transform infrared. Further, the cytotoxicity of the formulations was evaluated by 3-(4,5-dimethylthiazol-2-yl-2,5 diphenyltetrazolium bromide (MTT assay in A549, Calu-3, and Raw 264.7 cells. The diameter of NLC formulations was found to be in the range of 175–213 nm, and drug entrapping efficiency was found to be above 80%. In addition, high storage stability for the formulations was expected since they maintained the initial characteristics for 6 months. Moreover, the drug release was pH-sensitive, with a faster drug release at acidic pH than at neutral pH. These results pose a strong argument that the developed nanocarrier can be explored as a promising carrier for safer and more efficient management of tuberculosis by exploiting the pulmonary route of

  14. How we went digital without a strategy.

    Semler, R

    2000-01-01

    Once you say what business you're in, you put your employees into a mental straitjacket and hand them a ready-made excuse for ignoring new opportunities. So rather than dictate his company's identity, Ricardo Semler--the majority owner of Semco in São Paulo, Brazil--lets his employees shape it through their individual efforts and interests. "I don't know what Semco is," he writes in this first-person account of his company's expansion from manufacturing to Internet services. "Nor do I want to know." Ten years ago, Semco employees who were selling cooling towers to owners of large commercial buildings heard customers complain about the high cost of maintaining the towers. The salespeople proposed a new business in cooling-tower maintenance, and the venture is now a $30 million property-management business. That initiative led to the creation, with Semco's support, of an on-line exchange to facilitate the management of commercial construction projects. The exchange is revolutionizing the construction process in Brazil and has become a springboard for further Web initiatives such as virtual trade shows. The author shares some of the lessons he has learned along the way: Forget about the top line. Never stop being a start-up. Don't be a nanny (treat your employees like adults). Let talent find its place. Make decisions quickly and openly when it comes to reviewing proposals for new businesses. And partner promiscuously: "Our partners," Semler says, "are as much a part of our company as our employees."

This case report describes the evolution of an infectious crystalline keratopathy caused by Cladosporium sp., which developed after tectonic keratoplasty in a patient with a history of ocular trauma.Case presentation: A 40-year-old Brazilian male was the victim of firework-induced trauma to the left eye, which resulted in a corneal laceration that could not be sutured as well as a severe traumatic cataract. The patient underwent penetrating keratoplasty and phacoemulsification. During postoperative follow-up, another therapeutic keratoplasty was required because unresponsive infectious keratitis was observed. The infiltrate’s characteristics were suggestive of infectious crystalline keratopathy; in particular, the infiltrate was insidious and progressive, and grayish-white branches appeared in the anterior corneal stroma. As different therapies were administered, inflammatory reactions ranging from mild to severe were observed. The infection was unresponsive to typical antifungal drugs. This lack of response most likely occurred due to steroid treatment and the diffuse corneal spread of an atypical microorganism, which was subsequently identified in culture as Cladosporium sp. After the second therapeutic keratoplasty, the patient’s eye integrity was successfully reestablished.Conclusion: This study likely provides the first report describing a case of infectious crystalline keratopathy caused by Cladosporium sp. This case

    2017-03-01

    Full Text Available The main factors of economic growth in the mainstream of the economic theory are capital and labor, and the rates of growth are determined by the rate of savings. Alternative tradition of the economic analyses does accent on the structural changes that are taking place in the economic system. This restructuring is the main factor of development. This paper is a brief outline of the formation and evolution of the structuralist theory of economic growth. Elements of structuralism are standing yet in the concept of expanded reproduction of Marx, theory of comparative costs Ricardo, the model Solow. The characteristic of the concept of unequal exchange in international trade associated with the hypothesis Prebisch – Singer, describes the formation of a global system of «center – periphery». We introduce a distinction between the structuralist and neo-classical theories of economic growth associated with the discussions in the Soviet Union on the role of «extensive» and «intensive» growth factors. Considered in detail the model of «multi-level economy» Yuri Yaremenko as compared to the «economy of shortage» J. Kornai. The heterogeneity of the technological structure is present both in Soviet economy, as in the market, capitalist economy. The last situation was demonstrated by the concept of «technological stalemate» G. Mensch. As the impact of international economic relations on the economic development of the role of structural analysis will increase. The need for industries with increasing and diminishing returns, as well as the establishment of appropriate structural policies in their work justifies E. Reinert. His concept complements views Y. Yaremenko and G. Mensch on economic development.

  2. Reduced Order Modeling in General Relativity

    Tiglio, Manuel

    2014-03-01

    Reduced Order Modeling is an emerging yet fast developing filed in gravitational wave physics. The main goals are to enable fast modeling and parameter estimation of any detected signal, along with rapid matched filtering detecting. I will focus on the first two. Some accomplishments include being able to replace, with essentially no lost of physical accuracy, the original models with surrogate ones (which are not effective ones, that is, they do not simplify the physics but go on a very different track, exploiting the particulars of the waveform family under consideration and state of the art dimensional reduction techniques) which are very fast to evaluate. For example, for EOB models they are at least around 3 orders of magnitude faster than solving the original equations, with physically equivalent results. For numerical simulations the speedup is at least 11 orders of magnitude. For parameter estimation our current numbers are about bringing ~100 days for a single SPA inspiral binary neutron star Bayesian parameter estimation analysis to under a day. More recently, it has been shown that the full precessing problem for, say, 200 cycles, can be represented, through some new ideas, by a remarkably compact set of carefully chosen reduced basis waveforms (~10-100, depending on the accuracy requirements). I will highlight what I personally believe are the challenges to face next in this subarea of GW physics and where efforts should be directed. This talk will summarize work in collaboration with: Harbir Antil (GMU), Jonathan Blackman (Caltech), Priscila Canizares (IoA, Cambridge, UK), Sarah Caudill (UWM), Jonathan Gair (IoA. Cambridge.

    2014-09-01

    Full Text Available Ricardo Antonio Tan,1 Jonathan Corren2 1California Allergy and Asthma Medical Group, 2David Geffen School of Medicine at UCLA, Los Angeles, CA, USAAbstract: Pharmacologic treatment of asthma should be done with a stepwise approach recommended in treatment guidelines. If inhaled corticosteroids (ICSs alone are not adequate, ICSs in combination with long-acting β-agonists (LABAs are now established and widely used as the next step in effective controller therapy. Fixed-dose ICS/LABA combinations in a single device are the preferred form of delivery and improve compliance by enabling patients to get symptom relief from the LABA while receiving the anti-inflammatory benefits of ICSs. Fluticasone propionate/formoterol fumarate is one of the newest fixed-dose combinations. It has been in use in Europe in 2012, but is still under regulatory review in the US. Fluticasone is a synthetic ICS with potent anti-inflammatory effects, while formoterol is a selective β2-adrenergic receptor agonist with a rapid onset of bronchodilation within 5–10 minutes and a 12-hour duration of action. Fluticasone/formoterol has shown superior efficacy when compared to fluticasone or formoterol alone in multiple well-designed studies. The combination has shown comparable or “noninferior” benefits in lung function, clinical symptoms, and asthma control when compared with fluticasone and formoterol administered concurrently in separate inhalers. Fluticasone/formoterol provides similar efficacy with fluticasone/salmeterol, but with more rapid symptom relief. It has been compared directly with budesonide/formoterol with comparable results. Fluticasone/formoterol is well tolerated, with no unusual or increased safety concerns versus each individual component or other available ICS/LABA combinations. Fluticasone/formoterol is the latest entry into a relatively crowded market of branded fixed-dose preparations. Upcoming generic fixed-dose combinations and once-daily agents

    Since the 1970's, quadrupole mass spectrometer (QMS) systems have served as low-risk, cost-efficient means to explore the inner and outer reaches of the solar system. These legacy instruments have interrogated the compositions of the lunar exosphere (LADEE), surface materials on Mars (MSL), and the atmospheres of Venus (Pioneer Venus), Mars (MAVEN) and outer planets (Galileo and Cassini-Huygens). However, the in situ detection of organic compounds on Mars and Titan, coupled with ground-based measurements of amino acids in meteorites and a variety of organics in comets, has underlined the importance of molecular disambiguation in the characterization of high-priority planetary environments. The Mars Organic Molecule Analyzer (MOMA) flight instrument, centered on a linear ion trap, enables the in situ detection of volatile and non-volatile organics, but also the characterization of molecular structures through SWIFT ion isolation/excitation and tandem mass spectrometry (MSn). Like the SAM instrument on MSL, the MOMA investigation also includes a gas chromatograph (GC), thereby enabling the chemical separation of potential isobaric interferences based on retention times. The Linear Ion Trap Mass Spectrometer (LITMS; PI: William Brinckerhoff), developed to TRL 6 via the ROSES MatISSE Program, augments the core MOMA design and adds: expanded mass range (from 20 - 2000 Da); high-temperature evolved gas analysis (up to 1300°C); and, dual polarity detector assemblies (supporting the measurement of negative ions). The LITMS instrument will be tested in the field in 2017 through the Atacama Rover Astrobiology Drilling Studies (ARADS; PI: Brian Glass) ROSES PSTAR award. Following on these advancements, the Advanced Resolution Organic Molecule Analyzer (AROMA; PI: Ricardo Arevalo Jr.), supported through the ROSES PICASSO Program, combines a highly capable MOMA/LITMS-like linear ion trap and the ultrahigh resolution CosmOrbitrap mass analyzer developed by a consortium of five

    El 24 de enero de 1965 moría Sir Winston Churchill, unos dos meses después de haber cumplido su nonagésimo aniversario y a los 9 días de haber entrado en coma por un tercer y último accidente cerebro vascular.

    Fue un hombre extraordinario, el mejor estadista que ha tenido Inglaterra y uno de los personajes
    más importantes del siglo XX.

    Fue longevo a pesar de su agitada existencia y de la presencia de muchas dolencias que le aquejaron, confirmando aquel dicho de que los más enfermos son los que más viven. Recordando el libro de Accoce “Los enfermos que nos gobiernan”, y habiendo visitado la casa de Chartwell en unas vacaciones en el Reino Unido, el académico Ricardo Rueda González se dedicó a investigar y a conseguir datos sobre la historia médica de Winston Spencer Churchill, logrando en medio de apuntes de aquí y de allá, y con la ayuda de personal de nuestra corporación, la elaboración de un estupendo libro con ese título, en buena hora publicado por la Universidad Javeriana.

    Sobra decir que esta muy bien escrita obra se la lee uno de un tirón, dado el estilo fácil del autor, lo bien documentada que está y el interesante anecdotario, pues la vida de este gigante de la raza humana fue una permanente anécdota.

    2015-12-01

    The parabolic trough is the most established CSP technology and carries a long history of design experimentation dating back to the 1970’s. This has led to relatively standardized collector architectures, a maturing global supply chain, and a fairly uniform cost reduction strategy. Abengoa has deployed more than 1,500MWe of CSP troughs across several countries and has built and tested full-scale prototypes of many R&D concepts. The latest trough R&D efforts involved efforts to internalize non-CSP industry experience including a preliminary DFMA principles review done with Boothroyd Dewhurst, a construction literature review by the Arizona State University School of Construction Management, and two more focused manufacturing engineering subcontracts done by Ricardo Inc. and the nonprofit Edison Welding Institute. The first two studies highlighted strong opportunities in lowering part count, standardizing components and fasteners, developing modular designs to support prefabrication and automation, and devising simple, error-proof manual assembly methods. These principles have delivered major new cost savings in otherwise “mature” products in analogous industries like automotive, truck trailer manufacture, metal building fabrication, and shipbuilding. For this reason, they were core in the design development of the SpaceTube® collector, and arguably key to its early successes. The latter two studies were applied specifically to the first-generation SpaceTube® design and were important in setting the direction of the present SolarMat project. These studies developed a methodology to analyze the costs of manufacture and assembly, and identify new tooling concepts for more efficient manufacture. Among the main opportunities identified in these studies were the automated mirror arm manufacturing concept and the need for a less infrastructure-intensive assembly line, both of which now form central pillars of the SolarMat project strategy. These new designs will be

Scanning electron microscopy demonstrated that these microparticles were almost spherical, with development of surface wrinkling as the methylprednisolone load in the formulation was increased. The methylprednisolone load also had a direct influence on the mean diameter and zeta potential of the microparticles. Interactions between formulation excipients and the active drug were evaluated by x-ray diffraction, differential scanning calorimetry, and thermal gravimetric analysis, showing limited amounts of methylprednisolone in a crystalline state in the loaded microparticles. The encapsulation efficiency of methylprednisolone was approximately 89% in all formulations. The rate of methylprednisolone release from the microparticles depended on the initial drug load in the formulation. In vitro cytotoxic evaluation using THP-1 cells showed that none of the formulations prepared triggered an inflammatory response on release of interleukin-1ß, nor did they affect cellular viability, except for the 9.1% methylprednisolone formulation, which was the maximum test concentration used. The microparticles developed in this study have characteristics amenable to a therapeutic role in

  14. Status rent in new developing economy

    Full Text Available The status rent and conditions of its appearance are characterized in new developing economy by the position of new political economy. The bases of the general theory of rent were laid by classicists of political economy (F. Cene, A. Smith, J. Anderson, J. Mill, T. Maltus, D. Ricardo, K. Marx. They differentiated the rare rent (natural, absolute rent and differential land rent. Neoclassicists widened the definition of rent understanding it as income from any productive factor not only from land. Mostly, investigators of rent keep to two main postulates. Firstly, it is over profit, the income of special kind connected with using of exclusive, limited or rare goods for some time. Secondly, the rent is owned by the owners of these goods. These statements belonging to the natural rent can be used for the analysis of others, unnatural kinds of rent. The status rent belongs here. Let us analyze the status rent from the position of new political economy. As old political economy the new one also has its object - economic relations in the society and it call for the opening of deep, important processes of economic life. But by contrast with old political economy the new one, firstly, is based on other methodology (institutional economy, the theory of social choice, system approach; secondly, it studies economic relations not as static (the position of different classes, but as dynamic in economic behavior; thirdly, it is not confrontational: economic relations are understood not as antagonistic with non-avoidance of social cataclysm but as conflict-compromising; fourthly, it operates not only with social aggregates (class, country, social group, but it is also directed to a person, his/her freedom of choice in economic behavior; and, finally, fifthly, it overcomes the past careful marking out of other sciences, and, on the contrary, strives for an interdisciplinary approach in the stream of modern institutionalism including the problems of sociology

Functionality consists of the activities that an individual can perform, as well as their social participation, which is an important factor in analyzing the carrier living conditions of subjects with psychiatric suffering. Several studies have evaluated functionality in bipolar disorder; however, no studies have evaluated the functionality in other mental disorders. There are also few studies investigating the association between functionality and the biological bases of mental disorders. This study aimed to evaluate the serum NGF levels in psychiatric patients and to verify a possible association between the serum neurotrophic levels and functionality. This was a cross-sectional study with a convenient sample obtained from the Public Mental Health Service from the south of Brazil. The final sample was composed of 286 patients enrolled from July 2013 to October 2014. Data was collected using a sociodemographic questionnaire, and the diagnosis was confirmed using the Mini International Neuropsychiatric Interview (M.I.N.I and a Functioning Assessment Short Test. The serum NGF levels were determined using the enzyme-linked immunosorbent assay method. Statistical analyses were performed using IBM SPSS Statistic

However, only one randomized, controlled trial of pharmacotherapy (valproate in this patient population was published as of 2006. Therefore, we reviewed clinical trials in this indication of the last four years (using mood stabilizers, atypical antipsychotics, and other drugs. Priority was given to randomized trials, comparing drugs with placebo or active comparator. Published studies were found through systematic database search (PubMed, Scirus, EMBASE, Cochrane Library, Science Direct. In these last four years, the only randomized, clinically relevant study in bipolar patients with comorbid alcoholism is that of Brown and colleagues (2008 showing that quetiapine therapy decreased depressive symptoms in the early weeks of use, without modifying alcohol use. Several other open-label trials have been generally positive and support the efficacy and tolerability of agents from different classes in this patient population. Valproate efficacy to reduce excessive alcohol consumption in bipolar patients was confirmed and new controlled studies revealed its therapeutic benefit to prevent relapse in newly abstinent alcoholics and to improve alcohol hallucinosis.

Hence, it is pivotal to understand their behavior in terms of intracellular transport and toxicological effects. In this study, we focused on 3-mercaptopropionic acid-coated CdSe-CdS/ZnS core-multishell quantum dots (3MPA-QDs converted from the as-grown octadecylamine-coated quantum dots (ODA-QDs and their direct and dynamic interactions with human umbilical vein endothelial cells (HUVECs. Live cell imaging using confocal fluorescence microscopy showed that 3MPA-QDs first attached to and subsequently aggregated on HUVEC plasma membrane ~25 min after QD deposition. The aggregated QDs started being internalized at ~2 h and reached their highest internalization degree at ~24 h. They were released from HUVECs after ~48 h. During the 48 h period, the HUVECs responded normally to external stimulations, grew, proliferated and wound healed without any perceptible apoptosis. Furthermore, 1 3MPA-QDs were internalized in newly formed LysoTracker-stained early endosomes; 2 adenosine 5'-triphosphate-induced [Ca2+]i modulation caused a transient decrease in the fluorescence of 3MPA-QDs that were attached to the plasma membrane but a transient increase in the internalized 3MPA-QDs; and 3 fluorescence signal modulations of co-stained LysoTracker and QDs induced by the lysosomotropic agent Gly-Phe-β-naphthylamide were spatially co-localized and temporally synchronized. Our findings suggest that 3MPA

Chalcones were recently found to be potent and specific inhibitors, but unfortunately display a significant cytotoxicity. A cellular screening against ABCG2-mediated mitoxantrone efflux was performed here by flow cytometry on 54 chalcone derivatives from three different series with a wide panel of substituents. The identified leads, with submicromolar IC50 (half maximal inhibitory concentration values, showed that the previously identified 2'-OH-4',6'-dimethoxyphenyl, as A-ring, could be efficiently replaced by a 2'-naphthyl group, or a 3',4'-methylenedioxyphenyl with lower affinity. Such a structural variability indicates polyspecificity of the multidrug transporter for inhibitors. At least two methoxyl groups were necessary on B-ring for optimal inhibition, but substitution at positions 3, 4, and 5 induced cytotoxicity

  4. CONCEPTS AND METODOLOGIES REGARDING THE IMPROVEMENT OF ROMANIAN FOREIGN TRADE (I

    Full Text Available The purpose of the current paper is to highlight possible engines that can boost Romanian foreign trade from a chronic deficit to a more balanced one. In the beginning, the main theories and models that tackle this subject will be presented. In this respect, the paper starts with Smith, Ricardo, Manoilescu and Heckscher-Ohlin, in order to see the historic thought of trade model development. Following these models, a more mathematical approach will be made, using a thorough analysis at the product level. All the computations will be based on the combined nomenclature with its XXII classes, being the most exact determinant of traded goods. This paper uses the statistical indicators of Michaely and Lafay, in order to determine the specialization effect of the Romanian classes for a period of twenty one years, starting with 1991 and ending in 2012. This is the point where former, current and future specialized engines of potential trade growth can be established. It is crucial for a country to determine its potential in an open international arena, in order to take the necessary steps to encourage or discourage productive or non-productive areas of certain industry branches. Based on the results and on the previous methodology, a mix of theory with solid mathematical analysis, will gives the opportunity to draw up different sets of sustainable development formulas in order to obtain a higher concentration ratio regarding several classes from the combined nomenclature. For Romania to obtain higher gains from international trade, a more sustainable integration in the European Union, it has to stop its chronic balance of trade deficit. Looking at and analysing the potential development of a combined nomenclature class or classes, will help improving Romania’s chronic deficit, offering a long term prospective of sustainable development, reducing its foreign debt, improving its balance of trade accounts, and transforming its import driven economy to a

    During the last years an intensive national program was developed to determine the environmental radioactivity levels in Venezuela. Gamma dose and the radon concentrations indoors, in drinking water, in caves and in artificial cavities including the effect of radon transported to the surface with the earth gas have been studied. To continue this project the oil and other natural energy resource should be considered. It is expected that the environmental radiation level is modified in regions where the oil industrial activity is more aggressive such as in the Zulia State and the Faja Petrolifera del Orinoco, (Central Region). In these regions Venezuela is producing 1.750 thousand barrels of oil from the near-to-the- surface or deep oil drilling. Petroleum constitutes an important source of energy and as the majority of natural source contains radionuclides and their disintegration products, being U, Ra, Pb, Bi, Po and K the most often encountered. The combustion of petroleum concentrate in the ashes those radioelements, and later enter the environment by different ways producing adverse effects on the quality of man life. The concentration of radioelements varies greatly between oil fields, then we still requiring local survey studies in this area. Moreover due to the recent national interest in recycling processes, it becomes important to take precaution in the selection of materials that may contain by-products of industrial origin, including oil. In fact the oil ashes, oil slurry and other mining by-products are thought to be employable in the building industry. The concentration of radioactivity in the ash from thermoelectric power plants that use petroleum as a primary energy source was determined. The analysis include the two major thermoelectric power plants in Venezuela, Ricardo Zuluaga on the northern sea side of Caracas and Planta Centro on the littoral of Carabobo State. The study cover different samples: fuel oil No 6, ashes, heavy and medium petroleum

Thrombosed arteriovenous (AV fistulas with large venous aneurysms have poor treatment results, with both endovascular and surgical techniques, leading to a high rate of definitive AV access loss. The purpose of this study was to review the feasibility and initial results of this novel endovascular treatment of thrombosed AV fistulas with large venous aneurysms.Materials and methods: A novel endovascular treatment technique of inserting nitinol auto-expandable uncovered stents stretching through the whole puncture site area, thus creating a tunnel inside the thrombus, was retrospectively analyzed and described.Results: A total of 17 stents were placed in 10 hemodialysis fistulas, with a mean venous coverage length of 17.8 cm. In all the cases, 100% technical success was achieved, with complete restoration of blood flow in all patients. There were no procedure-related complications. The mean follow-up was 167 days (range 60–420 days, with a primary and assisted patency of 80% and 100%, respectively. No multiple trans-stent struts-related complications were observed. Three stent fractures were diagnosed with plain films at the site of puncture without consequence in the venous access permeability.Conclusion: The “stent tunnel technique” is a feasible, safe and effective alternative to salvage native hemodialysis access, thus extending the function of the venous access with

    The University of Minnesota collaborated with the Paul Scherrer Institute, the University of Wisconsin (UWI) and Ricardo, Inc to physically and chemically characterize the exhaust plume from recruited gasoline spark ignition (SI) vehicles. The project objectives were: (1) Measure representative particle size distributions from a set of on-road SI vehicles and compare these data to similar data collected on a small subset of light-duty gasoline vehicles tested on a chassis dynamometer with a dilution tunnel using the Unified Drive Cycle, at both room temperature (cold start) and 0 C (cold-cold start). (2) Compare data collected from SI vehicles to similar data collected from Diesel engines during the Coordinating Research Council E-43 project. (3) Characterize on-road aerosol during mixed midweek traffic and Sunday midday periods and determine fleet-specific emission rates. (4) Characterize bulk- and size-segregated chemical composition of the particulate matter (PM) emitted in the exhaust from the gasoline vehicles. Particle number concentrations and size distributions are strongly influenced by dilution and sampling conditions. Laboratory methods were evaluated to dilute SI exhaust in a way that would produce size distributions that were similar to those measured during laboratory experiments. Size fractionated samples were collected for chemical analysis using a nano-microorifice uniform deposit impactor (nano-MOUDI). In addition, bulk samples were collected and analyzed. A mixture of low, mid and high mileage vehicles were recruited for testing during the study. Under steady highway cruise conditions a significant particle signature above background was not measured, but during hard accelerations number size distributions for the test fleet were similar to modern heavy-duty Diesel vehicles. Number emissions were much higher at high speed and during cold-cold starts. Fuel specific number emissions range from 1012 to 3 x 1016 particles/kg fuel. A simple

Notwithstanding, no studies have as yet investigated the effects of resistance training on metabolic syndrome in postmenopausal women. Thus, the purpose of this study was to verify whether resistance training could reduce the risk of metabolic syndrome in postmenopausal women. Methods: Twenty postmenopausal women were randomly assigned to a resistance training protocol (n = 10, 53.40 ± 3.95 years, 64.58 ± 9.22 kg or a control group (n = 10, 53.0 ± 5.7 years, 64.03 ± 5.03 kg. In the resistance training protocol, ten exercises were performed, with 3 × 8–10 maximal repetitions three times per week, and the load was increased every week. Two-way analysis of variance was used to evaluate specific metabolic syndrome Z-score, high density lipoprotein cholesterol, fasting blood glucose, triglycerides, waist circumference, blood pressure, strength, and body composition. The level of statistical significance was set at P < 0.05. Results: The main results demonstrated a significant decrease of metabolic syndrome Z-score when the postmenopausal women performed resistance training (P = 0.0162. Moreover, we observed decreases in fasting blood glucose for the resistance training group (P = 0.001, and also significant improvements in lean body mass (P = 0.042, 2.46%, reduction of body fat percentage (P = 0.001, −6.75% and noticeable increases in

    Full Text Available O presente artigo apresenta os resultados de uma dissertação de mestrado em educação, realizada entre janeiro de 2004 a dezembro de 2006, sobre o processo de organização político-sindical dos profissionais da educação em Santa Catarina, mais particularmente no Oeste de Santa Catarina. O propósito fundamental desta pesquisa foi descrever a trajetória das lutas empreendidas pela categoria no período entre 1988 e 2006. Tomando como referência os mais importantes trabalhos sobre organização sindical no Brasil, desenvolvidos por Ricardo Antunes, Armando Boito, Leôncio Martins Rodrigues e outros, este trabalho descreve os processos de organização político-sindical dos docentes no Oeste de Santa Catarina. Por meio da pesquisa documental e das técnicas de memória oral, procurou-se conhecer as experiências vivenciadas pelos dirigentes sindicais envolvidos nesse processo. A investigação demonstrou que a organização política dos professores em Santa Catarina chegou ao seu ápice com a criação do Sindicato dos Trabalhadores em Educação (Sinte, em 1998, finalizando a forte tradição assistencialista alimentada pela Associação Catarinense dos Professores (ACP e a Associação dos Licenciados de Santa Catarina (Alisc, fundadas, respectivamente, em 1952 e 1966. O Sinte fortaleceu politicamente a categoria e foi decisivo para a conquista de inúmeros direitos trabalhistas para a categoria docente em Santa Catarina. A pesquisa mostra, também, que a partir da segunda metade dos anos 90 o movimento político-sindical dos professores começa a enfrentar dificuldades de mobilização e inicia um processo gradativo de enfraquecimento e deslegitimação, inclusive entre os professores e a comunidade escolar. O sindicalismo de luta foi substituído pelo de negociação.

However, several reports of their antiallodynic properties have been published in recent years. Although this effect has been considered mostly due to a GLT1 overexpression, these molecules have also been proven to induce direct immunomodulation. In this work, we determine the acute analgesic effect of CFX and CA in an inflammatory pain model and assess if their administration may induce anti-inflammatory effects. Methods: The carrageenan (Carr test was used as an inflammatory pain model. Both mechanical and thermal responses were analyzed after CFX and CA administration at different times. A plethysmometer was used to determine inflammation. Also, TNF-α and IL-10 serum concentrations were determined by enzyme-linked immunosorbent assay. Results: Both CFX and CA induced a significant thermal antiallodynic effect 3 and 24 h after administration. Furthermore, CA induced a mechanical antiallodynic effect 30, 60, and 90 min after administration. Moreover, a significant anti-inflammatory effect was found for both molecules 24 h after Carr injection. Also, both CA and CFX modulated TNF-α and IL-10 serum concentrations at different times. Conclusion: Our results provide evidence that both CFX and CA cause an analgesic effect on a Carr

    Full Text Available La historia de la traducción literaria en Costa Rica ya tiene buena documentación académica que corrobora su desarrollo y su persistencia. Desde los años tempranos del siglo xx, no pocos escritores dedicaron su pluma, a modo de oficio paralelo, tanto a su creación literaria como a la traducción. Sin duda alguna, porque las obras que tradujeron significaban, en buena medida, sus verdaderos modelos de escritura, pero también porque como traductores, entendieron desde temprano que misión suya era también verter al español, y para Costa Rica, obras que de otro modo difícilmente se conocerían con prontitud en el medio. Un insigne escritor costarricense de aquella etapa inicial de las letras nacionales fue Alejandro Alvarado Quirós (1876-1945, autor de crónicas, crítica literaria y ensayos de singular interés. Como escritor asociado al modernismo costarricense, fue asiduo lector de las letras francesas de la segunda mitad del siglo xix, y varios de los grandes narradores del realismo y el simbolismo francés fueron sus preferidos. En 1912 reunió en el pequeño tomo titulado Lilas y resedas (Imprenta Alcina, San José varios cuentos franceses, especialmente del ilustre cuentista Guy de Maupassant. De esa colección se han extraído dos, para esta sección de Letras: «Nuestras cartas» y «Adiós», que pulcramente Alvarado Quirós vertió al español; desde luego, un español culto, al modo del discurso modernista, como conscientemente el traductor ejecutó su labor. Como Alvarado Quirós, no pocos modernistas se vieron seducidos por el oficio de traducir: Roberto Brenes Mesén, Ricardo Fernández Guardia, Fabio Baudrit, José Fabio Garnier. Fue una empresa que se fue convirtiendo en tarea obligada y, con el tiempo, en una especie de tradición solapada, que hasta nuestros días se extiende.

    Full Text Available Ana LLinares, Francisco Javier Badesa, Ricardo Morales, Nicolas Garcia-Aracil, JM Sabater, Eduardo Fernandez Biomedical Neuroengineering, Universidad Miguel Hernández de Elche, Elche, Spain Purpose: This paper examines the influence of age on several attributes of sensorimotor performance while performing a reaching task. Our hypothesis, based on previous studies, is that aged persons will show differences in one or more of the attributes of sensorimotor performance. Patients and methods: Fifty-one subjects (aged 20–80 years with no known neuromotor disorders of the upper limbs participated in the study. Subjects were asked to grasp the end-effector of a pneumatic robotic device with two degrees of freedom in order to reach peripheral targets (1.0 cm radius, "quickly and accurately", from a centrally located target (1.0 cm radius. Subjects began each trial by holding the hand within the central target for 2000 milliseconds. Afterwards, a peripheral target was illuminated. Then participants were given 3000 milliseconds to complete the movement. When a target was reached, the participant had to return to the central target in order to start a new trial. A total of 64 trials were completed and each peripheral target was illuminated in a random block design. Results: Subjects were divided into three groups according to age: group 1 (age 20–40 years, group 2 (age 41–60 years, and group 3 (age 61–80 years. The Kruskal–Wallis test showed significant differences (P < 0.05 between groups, except for the variables postural speed in the dominant arm, and postural speed and initial deviation in the non-dominant arm (P > 0.05. These results suggest that age introduces significant differences in upper-limb motor function. Conclusion: Our findings show that there are objective differences in sensorimotor function due to age, and that these differences are greater for the dominant arm. Therefore for the assessment of upper-limb function, we should

    孙尚诚

    2012-01-01

    David Ricardo opened the new era of modern free trade. However, there are little thought, or misreading about Ricardo's economic ethics. Ricardo's economic ethics mainly expressed utilitarianism, the principle of "the greatest happiness of the greatest number" is most clearly reflected by his theory of comparative advantage. The theory still has general signifi- cance towards many fields until today. But there are also some scholars hold a kind of careful or even critical attitude to- wards it, and misread Ricardo's economic ethics via "Comparative Advantage Trap". The misreading, from the apparently sense, makes the theory of comparative advantage be wrong questioned, and from a more profound point of view, probably makes utilitarianism be blamed beyond necessity.%大卫·李嘉图开启了近现代自由贸易的全新时代,但对于李嘉图的经济伦理思想却鲜有梳理或是有所误读。李嘉图的经济伦理思想主要是功利主义的,其比较优势理论最为集中地体现了“最大多数人的最大幸福”原则,直到今天仍对诸多领域有一般性指导意义。然而,也有一些学者对其持审慎甚至批评的态度,并以“比较优势陷阱”误读李嘉图的经济伦理思想。这种误读从表层来说是使比较优势学说遭到了错误的质疑,从更深层来说则很有可能使得功利主义受到的诘难超越了其应该遭遇的尺度。

Methods: Sixty-nine biopsies were collected for immunohistochemical analysis for the presence of IL-6, IL-8, TNF-α, IFN-γ, TGF-β, and IL-10, in 16 fragments from atheromatous plaques, 32 aorta fragments, and 21 valve fragments, using a tissue microarray technique for paraffin embedded tissues. Results: Most patients undergoing revascularization surgery were men >50 years, while those undergoing valve replacement were mostly women <50 years. TNF-α was the most prevalent marker, detected in 91.7% (55/60 of the samples. The mean percent area stained was greater in patients infected with C. pneumoniae (3.81% vs 1.92%; p=0.0115 and specifically in the aorta (4.83% vs 2.25%; p=0.0025; C. trachomatis infection was higher in valves, and C. pneumoniae in plaques, both without statistical significance. There was no significant difference in the cytokine staining profile between patients previously infected with both species and uninfected patients.

  20. Thermal barrier coatings application in diesel engines

    Fairbanks, J. W.

    1995-01-01

    Commercial use of thermal barrier coatings in diesel engines began in the mid 70's by Dr. Ingard Kvernes at the Central Institute for Industrial Research in Oslo, Norway. Dr. Kvernes attributed attack on diesel engine valves and piston crowns encountered in marine diesel engines in Norwegian ships as hot-corrosion attributed to a reduced quality of residual fuel. His solution was to coat these components to reduce metal temperature below the threshold of aggressive hot-corrosion and also provide protection. Roy Kamo introduced thermal barrier coatings in his 'Adiabatic Diesel Engine' in the late 70's. Kamo's concept was to eliminate the engine block water cooling system and reduce heat losses. Roy reported significant performance improvements in his thermally insulated engine at the SAE Congress in 1982. Kamo's work stimulates major programs with insulated engines, particularly in Europe. Most of the major diesel engine manufacturers conducted some level of test with insulated combustion chamber components. They initially ran into increased fuel consumption. The German engine consortium had Prof. Woschni of the Technical Institute in Munich. Woschni conducted testing with pistons with air gaps to provide the insulation effects. Woschni indicated the hot walls of the insulated engine created a major increase in heat transfer he refers to as 'convection vive.' Woschni's work was a major factor in the abrupt curtailment of insulated diesel engine work in continental Europe. Ricardo in the UK suggested that combustion should be reoptimized for the hot-wall effects of the insulated combustion chamber and showed under a narrow range of conditions fuel economy could be improved. The Department of Energy has supported thermal barrier coating development for diesel engine applications. In the Clean Diesel - 50 Percent Efficient (CD-50) engine for the year 2000, thermal barrier coatings will be used on piston crowns and possibly other components. The primary purpose of the

  2. O retrato literário em duas Novelas Ejemplares de Cervantes: El amante liberal e La española inglesa

    Alberto Rodríguez

    2013-12-01

    Full Text Available Las novelas ejemplares “El amante liberal” y “La española inglesa” presentan la peculiar visión que Cervantes tenía del retrato literario. En ambas novelas, la imagen es cambiante. No hay nada estático porque todo participa del flujo constante de la vida. En “El amante liberal”, el retrato de Leonisa va ganando en profundidad, aunque su indumentaria se mantiene inalterable durante la novela. Con cada nueva aparición de la joven, los adornos que lleva en su persona pierden importancia. Dejamos lo cosmético y superficial a un lado para descubrir planos internos que antes no vislumbrábamos. En otras palabras, la imagen evoluciona, y se reconstituye a lo largo de la trama. Lo mismo ocurre con Ricardo, pues sufre transformaciones que lo convierten en una persona muy distinta al final. En “La española inglesa”, la reconstitución se puede palpar en el cambio físico de Isabela, que comienza con su bella apariencia, pasa a una horrenda fealdad, y termina recuperando su belleza primera. Después de la ambigüedad inicial de su figura, Ricaredo inicia una lenta evolución hasta alcanzar una forma definida y clara hacia el final. Su imagen ambigua se reconstituye en una imagen cuajada y bien definida. El narrador retratista inicia sus retratos con sobriedad y concisión, con un claro impulso mimético. No obstante, su presencia cambia con los desafueros imaginativos de sus retratos. Al final, se reconstituye su imagen porque regresa a su estilo mimético del principio.  En fin, el retrato literario cervantino muestra el devenir incansable de la vida y las mutaciones inevitables del tiempo; pero el proceso de reconstitución muestra la esencia de la persona en medio de las vicisitudes, los cambios y las peripecias de la existencia.

However, a systematic comparison of their activity in the relief of inflammation and pain models is still lacking.Materials and methods: The effects of Rvs E1 and D1 and protectin DX (PDX were assessed in rat paws inflamed by the standard proinflammatory stimulus carrageenan or by histamine, 5-hydroxytryptamine, substance P or prostaglandin E2. The experimental outcomes were the mechanical nociceptive threshold and increase in paw volume as a measure of pain and edema formation, respectively. The analgesic and anti-inflammatory activities of the indicated SPMs were also compared with nonsteroidal (indomethacin and celecoxib and steroidal (dexamethasone anti-inflammatory drugs.Results: Only RvE1 and RvD1 presented analgesic and anti-inflammatory activities in the carrageenan model, and RvE1 was twice as potent as RvD1. Both substances tended to be better analgesics than anti-inflammatory agents, with a modeling profile similar to steroidal anti-inflammatory drugs. However, proinflammatory effects (edema formation were also detected when the mediators histamine, 5-hydroxytryptamine or substance P replaced carrageenan as the proinflammatory stimuli. The analgesic and anti-inflammatory effects of resolvins were specifically prevented by an antagonist of the leukotriene B4 receptor 1 (BLT1.Conclusion: Rvs, as analgesic agents, may be better therapeutic agents than nonsteroidal anti-inflammatory drugs, the

  7. An experimental investigation into combustion and performance characteristics of an HCCI gasoline engine fueled with n-heptane, isopropanol and n-butanol fuel blends at different inlet air temperatures

    Uyumaz, Ahmet

    2015-01-01

    Highlights: • Combustion was retarded with the increase of the amount of isopropanol and n-butanol in the test fuels. • Combustion was advanced with the increase of air inlet temperature on HCCI combustion. • Isopropanol seems more suitable fuel due to controlling the HCCI combustion and preventing knocking. • Almost zero NO emissions were measured when alcohol used except for n-heptane and B20 test fuels. - Abstract: An experimental study was conducted in a single cylinder, four stroke port injection Ricardo Hydra test engine in order to determine the effects of pure n-heptane, the blends of n-heptane and n-butanol fuels B20, B30, B40 (including 20%, 30%, 40% n-butanol and 80%, 70%, 60% n-heptane by vol. respectively) and the blends of n-heptane and isopropanol fuels P20, P30, P40 (including 20%, 30%, 40% isopropanol and 80%, 70%, 60% n-heptane by vol. respectively) on HCCI combustion. Combustion and performance characteristics of n-heptane, n-butanol and isopropanol were investigated at constant engine speed of 1500 rpm and λ = 2 in a HCCI engine. The effects of inlet air temperature were also examined on HCCI combustion. The test results showed that the start of combustion was advanced with the increasing of inlet air temperature for all test fuels. Start of combustion delayed with increasing percentage of n-butanol and isopropanol in the test fuels. Knocking combustion was seen with B20 and n-heptane test fuels. Minimum combustion duration was observed in case of using B40. Almost zero NO emissions were measured with test fuels apart from n-heptane and B20. The test results also showed that CO and HC emissions decreased with the increase of inlet air temperature for all test fuels. Isopropanol showed stronger resistance for knocking compared to n-butanol in HCCI combustion due to its higher octane number. It was determined that n-butanol was more advantageous according to isopropanol as thermal efficiency. As a result it was found that the HCCI

As an original idea of Professor Ricardo Magnus Osorio Galvão, Director of Centro Brasileiro de Pesquisas Físicas, we saluted the creation of The Vladimir Tsypin Award to the best Poster in the meeting. This prize was presented by Professor Galvão in memoriam of Vladimir Semenovich Tsypin. It was suggested that the granting of this award be made in every meeting from now on. We think that it is very important to emphasise the mini-courses due to the necessity of increasing in the near future a better formation for our young scientists. The contributions of all the lecturers are greatly appreciated. We had the typical fields in plasma physics as in past meetings. We also appreciated very much the lectures of Professor Malcolm Haines, Professor Sergey Popel, Professor Claude Deutsch, and Professor Antony Peratt for their very interesting talks on the Z-Pinch recorded to prehistory. Special thanks again to these lecturers since they have joined and honoured our meetings in the past as well. As in the VII LAWPP, all the sessions of the workshop were held at the Universidad Simon Bolivar campus, located in the nice green Valley of Sartenejas near Caracas. We also appreciate the stimulus and the financial support that we have always had for the preparation of these workshops from our institution by means of its authorities: Professor Benjamin Sharifker (Rector), Professor Aura Lopez (Dean of Academic Activities), (Professor Jose Luis Paz (Dean of Research and Development), Professor Pedro Berrisbeitia (Dean of Postgraduate Studies) and Professor William Colmenares (Dean of Extended Activities). We must also mention and appreciate the collaboration of architect Alejandro Chataing Roncajolo as Secretary and Coordinator of the Congress, as well as the daily important collaborations of our students Anais M

  10. Notas sobre los avatares históricos de la revista "ARQUITECTURA" como medio de difusión de la innovación arquitectónica

    Full Text Available From 1918 to 1930, the journal published texts primarily dealing with history. Despite this historicism, news on the modernist revolution slipped into its pages.Beginning in or around 1930 it focused more on new architecture. Nonetheless, it maintained an eclectic policy and published many articles on non-modern subjects. After the Civil War, the government took it over in an attempt to promote neo-historicist architecture. From 1948 to 1972 its editor-in-chief was Carlos de Miguel. In 1956 it was returned to the Chartered Institution of Architects. This period was characterized by a professional bias, with a focus on chronicling Madrilenian and Spanish architecture. It was followed by short, erratic stages until 1976 under the leadership of Junquera and Pérez-Pita. After 1981, this same line was continued by Javier Frechilla, Gabriel Ruiz Cabrero and the author of this article, with a more learned and academic accent, but without losing sight of the professional chronicling and eclecticism that had guided previous stages. After 1987 the editors-in-chief were de la Mata, Nieto and Sobejano. Theirs was an interesting journal, but with a lower profi le. They were succeeded by Soriano and Porras, who gave the journal an avant-garde slant. Baldellou was editor-in-chief from 1993 to 2000, a period that merits rather harsh commentary. In 2000 José Ballesteros, Juan García Millán and Ricardo Sánchez-Lampreave took over; and later Antón Capitel and García Millán retrieved the journal’s values as a vehicle for architectural innovation and culture and for chronicling local, national and international events.La revista, de 1918 a 1930, era una publicación dedicada sobre todo a textos, generalmente de historia.

The complexity and diversity of the forms of socio-ecological and ecological-economic issues at different levels of the economic system leads to the development of many directions and views on the expansion of the management process of these levels (global, national, regional, local and techniques from rigid-deklorative state before combination with the market. In this respect, the neoclassical economic theory actively generated new analytical ideas and concept that enables to respond adequately to emerging economic realities. So we can distinguish the following approaches to regulate environmental management activities: T. Malthus and D. Ricardo, revealing issues of social, ecological and economic implications of limited natural resources in the context of the law of diminishing effectiveness and the need to regulate environmental management activities. John. St. Mill and George proved to be ineffective in addressing environmental problems in the industrial economy of the type of the imperfection of the institutions of society, justifying the occurrence of crises protohistoric speculation nature's benefits. A.

    INTRODUCCIÓN

    En la Nueva Granada de principios del siglo XIX solo existía una facultad o escuela de medicina, la del Colegio Mayor de Nuestra Señora del Rosario, en Bogotá. A partir de 1828 ya existían, en lo que hoy es Colombia, la Escuela de Medicina de la Universidad Central, la escuela de Medicina del Magdalena y el Istmo asentada en Cartagena, y sobrevivían las cátedras de medicina del Rosario y San Bartolomé, con sede en Bogotá; en 1864 se abrió en Bogotá la primera Escuela de Medicina, privada; en esa década de los sesenta del siglo XIX el Estado Soberano del Cauca reanudó y cerró los estudios de medicina en el Colegio del Estado, el Estado Soberano de Boyacá activó en 1869 en el Colegio de Boyacá la cátedra de medicina, de vida breve. A finales del siglo XIX solo existían las facultades de medicina de las universidades Nacional, de Antioquia y de Cartagena, y en 1920 el país seguía teniendo esas tres facultades de medicina en funcionamiento.

    Aunque se logró tener conocimiento de catorce libros, solo se exhiben 10 (uno por autor, a excepción de Nicolás Osorio y Ricaurte con dos, ambos exhibidos, y Luis Cuervo Márquez con dos, solo uno exhibido, con la ausencia de las obras de los autores Ricardo de La Parra, Juan de Dios Tavera Barriga y Gabriel D.

  14. El pintor de un ocaso. Enrique Loncán entre brindis y charlas de amigo

    Adriana Rodríguez Pérsico

    2012-10-01

    Full Text Available Durante las décadas de 1920 y 1930, una serie de escritores y periodistas cultivan la crítica política en textos que fusionan costumbrismo y humor. Con algunas excepciones, prefieren las formas breves, ya sea el cuento, el aguafuerte o la causerie. Arturo Cancela, Enrique Loncán, Enrique Méndez Calzada llegan con sus escritos a un público amplio porque colaboran en periódicos y revistas de gran tirada como La Nación, El Hogar, Caras y Caretas. Profundamente escépticos, son antiyrigoyenistas y a fuerza de tanto negativismo, antidemocráticos. El blanco de sus risas es el gobierno nacional y popular. Muestran una Argentina que, entre la ruina de las instituciones, se vislumbra como una sociedad en pedazos. Pero no sólo atentan contra los tiempos presentes. Los textos ponen en marcha una operación de desmitificación extendida de los grandes relatos nacionales. La risa y el estereotipo corroen los mitos creados por los escritores del Centenario como Leopoldo Lugones, Manuel Gálvez, Ricardo Rojas -para nombrar a los más representativos- que imaginan en sus ensayos identidades colectivas para la nación desplegando linajes reales o inventados. Los escritores nacionalistas se dan la tarea de crear un pasado para alimentar con memorias lo que veían como un desierto cultural e histórico. Los textos, que en su mayor parte adoptan la forma del ensayo monumental y totalizador, apuestan a consolidar la grandeza de la nación. Al construir la memoria colectiva, los relatos nacionales funcionan como archivos que guardan las tradiciones y establecen genealogías dando testimonio de un pasado primigenio. Enrique Loncán publica entre 1923 y 1936 cuatro volúmenes de causeries de título muy porteño, Las charlas de mi amigo en las que actualiza el género imprimiéndole la huella política. Elige las formas y los tonos de la causerie decimonónica para dotarlos de contenidos políticos. La jocosidad y la burla se unen para producir un tipo de

    youngest and oldest age groups in 7 countries). The incidence of ILI in Influenzanet was found to be closely correlated although quantitatively higher than that obtained by the sentinel medical practice networks. Various risk factors for acquiring an ILI infection were identified. The VE studies performed with Influenzanet data suggest that this surveillance system could develop into a complementary tool to measure the effectiveness of the influenza vaccine, eventually in real time. Results from these analyses illustrate that Influenzanet has developed into a fast and flexible monitoring system that can complement the traditional influenza surveillance performed by sentinel medical practices. The uniformity of Influenzanet allows for direct comparison of ILI rates between countries. It also has the important advantage of yielding individual data, which can be used to identify risk factors. The way in which the Influenzanet system is constructed allows the collection of data that could be extended beyond those of ILI cases to monitor pandemic influenza and other common or emerging diseases. ©Carl E Koppeschaar, Vittoria Colizza, Caroline Guerrisi, Clément Turbelin, Jim Duggan, W John Edmunds, Charlotte Kjelsø, Ricardo Mexia, Yamir Moreno, Sandro Meloni, Daniela Paolotti, Daniela Perrotta, Edward van Straten, Ana O Franco.

Presentamos hoy las intuiciones del teólogo católico australiano Denis Edwards, publicadas definitivamente en su libro de 2004. Profundo conocedor de la teología de Karl Rahner, parte de la intuición de la «autotrascendencia activa», pero la enriquece sustancialmente desde su opción filosófica por una «ontología relacional» y su profundo conocimiento de la tradición trinitaria y pneumatológica. Llega así a su intuición central que ve esa acción divina que posibilita la emergencia evolutiva a través de la autotrascendencia de las creaturas como función «propia» del Espíritu Santo, extático y dador-de-vida. Por otra parte, en su modernización de la «relación creadora» de Santo Tomás, intuye también esa relación como función «propia» del Espíritu Santo, extático y portador-de-koinonía. Como intuición previa, ve el interés de destacar estas funciones o papeles «propios de» (y no sólo «apropiados a» las personas divinas, dentro de la acción indivisa de la Trinidad sobre la creación. La primera parte del presente artículo presenta esas tres intuiciones en forma de tesis (§ 1.3.

User engagement was variable, with no clear patterns emerging in timing, topic, or type of post. Most participants were highly educated, urban dwelling, and female, limiting diversity and representativeness. The source of referral for most survey respondents was through Facebook or a friend, suggesting the importance of personal connections in the dissemination and uptake of information. User engagement with the Facebook-based discussion threads was inconsistent and difficult to initiate. Although there is substantial interest in the use of social media as a component of an effective patient engagement strategy, challenges regarding participant engagement, representativeness, obtaining buy-in, and resources required must be carefully considered. ©Michele P Dyson, Kassi Shave, Ricardo M Fernandes, Shannon D Scott, Lisa Hartling.

    Full Text Available El presente trabajo realiza un análisis de La tierra en armas, Los gauchos y “Gauchos y collas” en los que algunos personajes se presentan elaborados desde el paradigma del mestizaje. Los textos no constituyen descripciones del mestizo, del mestizaje o del proceso de su constitución (aunque los ensayos hacen pequeños aportes en este sentido como las realizadas por Uslar Pietri o por Fernando Ortiz. Se trata (y ésta es nuestra hipótesis de textos donde se construyen mestizos ideales para proponerlos como figuras de identificación en el marco de una doctrina política: el nacionalismo. El análisis se hizo siguiendo el modelo teórico-metodológico que Cornejo Polar utiliza para “desenmascarar” el hispanismo de la tesis de Riva Agüero sobre el Inca Garcilaso. A partir de comparaciones con las figuras mestizas construidas en otros textos, se encontraron similitudes con las de Riva Agüero con lo que se pensó en una posible raíz andina de los textos davalianos; pero se llegó a la conclusión de que éstos: 1.- están informados por un nacionalismo fuertemente hispanista a la manera de Manuel Gálvez y no al modo helenizante de Lugones 2.- están atravesados por un tenaz antiindigenismo, en las antípodas de una posición como la de Ricardo Rojas que daba importancia también a la vertiente indígena del mestizaje. Finalmente y a manera de conclusión se discute si, a comienzos del siglo XXI, tiene sentido “denunciar” hispanismo. O si, realizada en tantos ensayos la ponderación del mestizaje como característica de Hispanoamérica (aún cuando se haga sobresalir la vertiente hispana del mismo no sería preferible: 1.- ubicar los textos en sus condiciones productivas; 2.- preguntar por el lugar enunciativo desde dónde se “desenmascara” el hispanismo; 3.- ver si en los enunciados no se está estigmatizando todavía a España que —a diferencia de otras potencias imperiales— hizo posible la mezcla, y finalmente 4.- observar si, al

Methods: Ten older hypertensive women (age =71.1±5.5 years; body mass index =24.2±3.9; mean BP [MBP] =85.4±3.5 underwent a protocol consisting of BP and heart rate variability (HRV output assessments at baseline and during MS, and these measurements were taken before and 60 minutes after two bouts of RE (traditional and circuit. MS was induced through a computerized 3-minute Stroop color–word test before and 1 hour after each exercise session; BP was measured every minute during MS, and HRV was monitored as a measure of cardiac autonomic control. Results: A significant effect of time on systolic BP (∆pre =17.4±12.8 versus ∆post =12.5±9.6; P=0.01, diastolic BP (∆pre =13.7±7.1 versus ∆post =8.8±4.5; P=0.01, and MBP (∆pre =14.0±7.7 versus ∆post =9.3±5.4; P<0.01 after RE was observed, with no differences between the two sessions. In addition, a significant effect of time on log-normalized low-frequency component of HRV (ms2; 5.3±0.8 pre-exercise MS versus 4.8±1.0 baseline value; P=0.023 was also observed, showing a significant change from baseline to MS before RE, but not after RE sessions. These results may be related to a lessened RE-mediated cardiac sympathetic activity during MS. Conclusion: RE is an effective tool to reduce BP reactivity to MS, which could therefore be associated with an acute reduction in cardiovascular risk. This

In this study, the educational chain begins with the influence that CME can have on the quality of health care, with subsequent influence on patient knowledge, disease self-management, and disease biomarkers. Methods: A total of 422 patients with at least one noncommunicable disease (NCD treated in eight different Mexican public health clinics were followed over 3 years. All clinics were participants in the CASALUD Model, an NCD care model for primary care, where all clinic staff were offered CME. Data were collected through a questionnaire on health care, patient disease knowledge, and self-management behaviors; blood samples and anthropometric measurements were collected to measure patient disease biomarkers. Results: Between 2013 and 2015, the indexes measuring quality of health care, patient health knowledge, and diabetes self-management activities rose moderately but significantly (from 0.54 to 0.64, 0.80 to 0.84, and 0.62 to 0.67, respectively. Performing self-care activities – including owning and using a glucometer and belonging to a disease support group – saw the highest increase (from 0.65 to 0.75.

    The objective of the proposed project was to confirm the feasibility of using blends of hydrogen and natural gas to improve the performance, efficiency, controllability and emissions of a homogeneous charge compression ignition (HCCI) engine. The project team utilized both engine simulation and laboratory testing to evaluate and optimize how blends of hydrogen and natural gas fuel might improve control of HCCI combustion. GTI utilized a state-of-the art single-cylinder engine test platform for the experimental work in the project. The testing was designed to evaluate the feasibility of extending the limits of HCCI engine performance (i.e., stable combustion, high efficiency and low emissions) on natural gas by using blends of natural gas and hydrogen. Early in the project Ricardo provided technical support to GTI as we applied their engine performance simulation program, WAVE, to our HCCI research engine. Modeling support was later provided by Digital Engines, LLC to use their proprietary model to predict peak pressures and temperatures for varying operating parameters included in the Design of Experiments test plan. Digital Engines also provided testing support for the hydrogen and natural gas blends. Prof. David Foster of University of Wisconsin-Madison participated early in the project by providing technical guidance on HCCI engine test plans and modeling requirements. The main purpose of the testing was to quantify the effects of hydrogen addition to natural gas HCCI. Directly comparing straight natural gas with the hydrogen enhanced test points is difficult due to the complexity of HCCI combustion. With the same air flow rate and lambda, the hydrogen enriched fuel mass flow rate is lower than the straight natural gas mass flow rate. However, the energy flow rate is higher for the hydrogen enriched fuel due to hydrogen’s significantly greater lower heating value, 120 mJ/kg for hydrogen compared to 45 mJ/kg for natural gas.

A possible underlying hypothesis, limitation, and unmet need may be the inability of therapeutics to penetrate into dense bone mineral, which can lead to poor efficacy and high toxicity, due to drug uptake in healthy organs. The development of nanostructured formulations with high affinity for bone could be an interesting approach to overcome these challenges.Purpose: To develop a liposomal formulation with high affinity for hydroxyapatite and the ability to release doxorubicin (DOX in an acidic environment for future application as a tool for treatment of bone metastases.Materials and methods: Liposomes were prepared by thin-film lipid hydration, followed by extrusion and the sulfate gradient-encapsulation method. Liposomes were characterized by average diameter, ζ-potential, encapsulation percentage, X-ray diffraction, and differential scanning calorimetry. Release studies in buffer (pH 7.4 or 5, plasma, and serum, as well as hydroxyapatite-affinity in vitro analysis were performed. Cytotoxicity was evaluated by MTT assay against the MDA-MB-231 cell line, and biodistribution was

  12. From somatic pain to psychic pain: The body in the psychoanalytic field.

    Hartung, Thomas; Steinbrecher, Michael

    2017-03-24

    The integration of psyche and soma begins with a baby's earliest contact with his or her parents. With the help of maternal empathy and reverie, β-elements are transformed into α-elements. While we understand this to be the case, we would like to enquire what actually happens to those parts of the affect which have not been transformed? For the most part they may be dealt with by evacuation, but they can also remain within the body, subsequently contributing to psychosomatic symptoms. This paper describes how the body serves as an intermediate store between the psychic (inner) and outer reality. The authors focuses on the unconscious communicative process between the analyst and the analysand, and in particular on how psychosomatic symptoms can spread to the analyst's body. The latter may become sensitive to the analysand's psychosomatic symptoms in order to better understand the psychoanalytical process. Sensory processes (visual and auditory) and psychic mechanisms such as projective identification can serve as a means for this communication. One of the first analysts to deal with this topic was Wilhelm Reich. He described one kind of psychosomatic defence like a shell, the character armour, comparing the armour formed by muscle tension with another, more psychical type of armour. This concept can be linked to Winnicott's contribution of the false self and later on to Feldman's concept of compliance as a defence. The authors links further details of the clinical material with theoretical concepts from Joyce McDougall, Piera Aulagnier, and Ricardo Rodulfo and Marilia Aisenstein. With the aid of the complex concept of projective identification, as described by Heinz Weiss, the authors discusses the important question of how the analyst gets in touch with the patient's current psychosomatic state, and describes a specific communication between the body of the psychoanalyst and the body of the patient. A vignette illustrates in greater detail the relationship

The as-developed nanosized material device, consisting of surface decorated maghemite nanoparticles suspended as a biocompatible magnetic fluid (MF sample, labeled MF-anti-CEA, was characterized and tested against two cell lines: a high-CEA expressing cell line (LS174T and a low-CEA expressing cell line (HCT116. Whereas X-ray diffraction was used to assess the average core size of the as-synthesized maghemite particles (average 8.3 nm in diameter, dynamic light scattering and electrophoretic mobility measurements were used to obtain the average hydrodynamic diameter (550 nm and the zeta-potential (−38 mV of the as-prepared and maghemite-based nanosized device, respectively. Additionally, surface-enhanced Raman spectroscopy (SERS was used to track the surface decoration of the nanosized maghemite particles from the very first precoating up to the attachment of the anti-CEA moiety. The Raman peak at 1655 cm−1, absent in the free anti-CEA spectrum, is the signature of the anti-CEA binding onto the precoated magnetic nanoparticles. Whereas MTT assay was used to confirm the low cell toxicity of the MF-anti-CEA device, ELISA and Prussian blue iron staining tests performed with both cell lines (LS174T and HCT116 confirm that the as-prepared MF

    : provocations on university teaching  ABSTRACT This work shows the results of a conducted research which aimed to understand how the professional knowledge related to teaching by professors who teach in engineering courses at a public university in Bahia. Since the stricto sensu graduate programs are predominantly directed to the researcher’s formation, the investigation process revolved around the following guiding question: where and by which processes did teachers of engineering courses of a public university in Bahia built their professional knowledge related to teaching? This qualitative study is grounded in discussions made by authors who discuss University Pedagogy: Masetto (2012, Pimenta (2009, D'Ávila (2013, Soares (2009 and teacher training: Pimenta (2014; Marcelo Garcia (2012; Mizukami et. al. (2010 and Nono (2005. The collection of data was carried out by a socio-professional questionnaire, as well as the application of the teaching case entitled "Ricardo's Dilemma". The analysis of the data was based on the assumptions of the content analysis technique (BARDIN, 1977. The performed analysis allows us to assert that: a the teaching practice of university professors is based on model teachers that they had during their schooling process in basic and higher education. b The teaching profession, in higher education, is built daily, based on experience exchange with peers. c the teaching practice during the master's degree and the participation in training courses have been considered as driving elements in the learning processes of teaching and professional development of the subjects participating in our study.

    ísicas, dado ver nelas a ocorrência do retraimento da libido ao eu e o consequente abandono do mundo exterior. Ao contrário de Freud que tinha grande experiência para com o tratamento das neuroses, tanto Jung como Sandor Ferenczi tinham uma clínica com pacientes afetados por esquizofrenia e por paranoia e realizavam uma discussão constante desses caso com Freud, pelos quais mostrava um grande interesse. Freud, por sua vez, ao escrever o caso Schreber, baseado na biografia do mesmo, avança no entendimento da paranoia, a partir de meticulosa análise do desencadeamento e organização do delírio de Schreber, chegando a traçar sua gramática. Contribuição até hoje considerada fundamental para a clínica para com a psicose paranoica. Fruto de sua pesquisa de mestrado em psicologia na UFC, sob a orientação do Professor Ricardo Barrocas, esse livro testemunha o empenho em realizar uma análise com fundamentos epistemológicos e dados de relevância clínica acerca das contribuições recíprocas desses dois pensadores, situando-as tanto no contexto da história do pensamento psicopatológico, quanto no que diz respeito ao desenvolvimento de dois sistemas de pensamento, pensando-os em relação ao desenvolvimento de um mesmo conceito. Disso resulta uma análise cuja marca é o senso ético e o respeito que o autor dedica em seu trabalho de investigação aos dois pensadores, o que não costuma ser comum, uma vez que essa discussão é, amiúde, marcada por uma supervalorização da posição de um dos lados sobre o outro. E tal não ocorre, no contexto desse trabalho, uma vez que ele se fundamenta por sobre dados analíticos cuidadosamente tratados e que nos fazem avançar em relação a um entendimento mais efetivo e sistemático dos principais eixos conceituais e metodológicos que geraram a ruptura entre os dois colaboradores, mas também do que desses eixos cada um deles anexou do outro ao seu sistema de pensamento. O que justifica, inclusive, o fato de ambos, mesmo

    indexación de LATINDEX.             Cabe señalar que los artículos publicados abarcan una variedad de temas relacionados con la problemática teórica y con diversos recortes y tematizaciones provenientes del campo fenoménico de la enseñanza. Los abordajes que se efectúan se asientan en diversos marcos disciplinarios y enfoque teóricos que permiten interrogar y poner en “suspenso” la centralidad de lo fáctico o los marcos prescriptivos que han hegemonizado los discursos sobre la enseñanza al tiempo que amplían los marcos comprensivos del acontecimiento didáctico.             Particularmente en este número se ofrecen cinco artículos y tres notas de investigación junto a una reseña. El texto de Ricardo Crisorio, “Sujeto y cuerpo en educación”, analiza las distintas nociones de sujeto y la especificidad del sujeto en la educación así como las nociones de cuerpo. A partir de este rastreo y sus interrelaciones aborda el análisis de las prácticas de enseñanza en educación corporal. El trabajo de Marcelo Novas, “Schreber y su enseñanza”, recorre las propuestas de Freud y Lacan sobre el proceso identificatorio. A partir de estas conceptualizaciones explora las interrelaciones con la enseñanza.  En una línea similar, el texto de Adrián Villalba, “Cuando la enseñanza hace sujeto, el concepto de identidad cuestionado”, retoma los aportes conceptuales sobre la identificación, efectuados por Freud y Lacan, para interrogarse sobre el pretendido sujeto pasible de enseñanza. Por su parte, el artículo de Norma Rodríguez y Alexandre Fernandez Vaz, “Contenidos de la enseñanza: conceptualizaciones, crítica epistemológica, propuestas de intervención”, se articula en torno al desarrollo de la hipótesis que señala que la transición de una Educación Física centrada en una propuesta de objetivos tiene su correlato en el discurso de la ciencia moderna y que, una propuesta de una pedagogía por contenidos tiene su

    Full Text Available St. Simeon – the eternal ruler of the Serbs The article discusses the development of the cult of St. Simeon (Stefan Nemanja, ca. 1113–1199 in the thirteenth century as a core of the ruler’s ideology and a mirror of the political changes in Serbia. The main task is to discover when, how and why the founder of the Nemanidi dynasty became the first and eternal ruler of the Serbs, analyzing the choice of the biblical motifs and quotations in the introductions and in a number of other selected places in the main ideological texts of the period: two Hilandar Monastery charters, one written from the Grand Zhupan Stefan Nemanja himself in 1198, the other – written in 1207/8 by his son, Stefan the First-Crowned as well as three Vitae of St. Simeon, written by his sons St. Sava and St. Stefan and by the Hilandar’s hegumenos Domentian. The study applies the approach of biblical thematic clues, proposed by Ricardo Picchio, hitherto unused for these sources, and takes into consideration also some results obtained through the investigation of early Slavic Orthodox texts from the point of view of the same concept. One conclusion which was arrived at is that the same tradition of biblical exegesis con­cerning the concepts of the Unfailing Mercy and Continuity of the Apostleship and the motifs of Conversion/New Nations and the Blessed Generation of the Upright, is consistently used in Serbian text for the same purpose – the affirmation of one’s own saints and, through their cults, confirmation of own “institutions of salvation” (ruling dynasty, church organization, liturgical language as proceeding directly from God. In the three Vitae of St. Simeon different inherited models and patterns are adopted, corresponding to different versions of Ideal Ruler and of legitimization in changing political circumstances in Serbia and in European South-East in the thirteenth century. The last version, long lasting in Serbian political ideology, can be

    relativa, destacando-se no Capítulo XIV a determinação do trabalho produtivo como essencialmente produtor de mais-valia (MARX, 1988, p. 101. Em texto anterior, Tumolo (1996 havia enfrentado a temática do trabalho como princípio educativo, contrapondo autores que abordaram a questão da centralidade do trabalho como categoria analítica.  A hipótese do autor é a de que no enfrentamento dos detratores da centralidade do trabalho, autores como Ricardo Antunes padeceriam da “falta de radicalidade”, devido ao fato de não incluírem a categoria de trabalho produtivo em suas análises, limitando-se às categorias trabalho concreto e trabalho abstrato (idem, p. 54. Porém, se no primeiro texto o autor se limitou ao desenvolvimento da categoria de trabalho produtivo para a sustentação da inviabilidade da tese do trabalho como principio educativo, no texto apresentado na 24º Encontro da Anped, Tumolo é um pouco mais ousado em sua crítica, questionando se devido à impossibilidade do trabalho ser um principio educativo, seja na sociedade capitalista, seja na sociedade comunista, não seria o “prazer de viver” o principio educativo, já que tendencialmente a necessidade do trabalho seria minimizada (TUMOLO, 2001, p. 256. Saviani se apoia no Capítulo VI inédito de O Capital para afirmar o trabalho educativo constitui-se em uma modalidade de trabalho não material cujo produto não se separa da produção (MARX, s/d, p. 119.

    of biopolitics, calling the attention to distinctions and identities between historically different mechanisms of power. The author tries to call the attention to the polissemic character of the notion of biopolitics. In the fourth article, Cláudia Hausman Silveira, doctoral student at the Interdisciplinary Program of Post-Graduation in Human sciences (DICH at the Federal University of Santa Catarina (UFSC, presents the issue of the family health, comparing the models that have inspired the construction of the Program of Family Health in Brazil, observing their differences and similarities. Moreover, she makes a comparative analysis among the Cuban, English, Canadian and Brazilian models, concluding that the Program multiprofessional proposal of work in interdisciplinary teams, in accordance with the Only System of Health (SUS, can assist in the fulfillment of the health law in the country. In the fifth article, the environmental issue is treated under the pedagogical point of view. Clayton Ângelo Silva Costa, Master in Environmental Sciences (UEMG presents results of a research carried through with private school teachers in the city of Contagem, Minas Gerais, showing the obstacles involving the application of the environmental education interdisciplinary project, focusing aspects of the atmospheric pollution. The last article approaches aspects of the Humanitarian International law. Geovane Machado Alves, Master’s Degree student in Public Law from the University of the Vale do Rio dos Sinos (UNISINOS, starts from the concept of solidarity and humanitarian intervention, and questions the Brazilian performance in Haiti as well as the legal paradigm of the international solidarism and its repercussions. Closing this issue, the theme is the public university itself and its current impasses and challenges.

    Con estas palabras quiero destacar la vida del Dr. Rafael Villota Villota, el amigo de siempre, el compañero de nuestras faenas médicas en el Hospital San Pedro, en la Clínica Maridiaz del antiguo Seguro Social y en el Capítulo de la Academia, durante muchos años.

    Lo suyo viene a ser una pérdida irreparable, lo es para su esposa Isabel, para sus hijos, nietos y familiares cercanos, para sus conciudadanos, para la Academia Nacional de Medicina, Capítulo de Nariño, a la cual sirvió de manera ejemplar.

    Fue un ser humano excepcional, una verdadera gloria de la medicina nariñense. El honró a la Academia con la dignidad de su conducta ejemplar. Su vida estuvo plena de virtudes. Tan agradable era su compañía que en Navidad prendía corazones sin necesidad de mecha. Consentido y cariñoso, su estirpe y su nobleza en llave con Isabelita, siempre los hizo ver como un matrimonio feliz. Alguna vez, en una noche incierta, en su casa, cuando el electrocardiograma no daba señales, contribuí a su alegría con la atropina, cuando Isabelita no estaba dispuesta a dejarlo solo. Él fue uno de los más puros y radiantes valores, con unas convicciones éticas firmes en su paso por la vida. Ahora, está en el seno del Señor junto con Eduardo Trujillo, Ricardo Zarama, Wladimiro Álvarez, Néstor Moncayo, Alfonso Rebolledo, Luis Eduardo Martínez, Luis Carlos Moncayo Navarrete, fundadores del Capítulo de Nariño de la Academia Nacional de Medicina en 1996. Con ellos, la confianza fue total, llena de naturalidad y afecto, dispuestos a encontrar nuevos horizontes para la Institución. Fueron en verdad, seres paradigmáticos, incomparables.

    Su muerte, ocurrida ya hace más de dos meses, afecta en grado mayor a quienes tuvimos el privilegio de su amistad, empeñados en mejorar los servicios hospitalarios, tal como ocurrió en el Hospital San Pedro y en la Clínica del Seguro Social. Bajo la Dirección del Dr. Luis Díaz del Castillo

    Pasto, mi ciudad, tiene su encanto propio. Es diferente a las demás ciudades; por la idiosincrasia de su gente y su forma de hablar y de pensar y por esa demarcación geográfica que nos aísla irremediablemente como un veredicto bíblico; hacia el norte por los eriales inconmensurables que llegan hasta Rosas y por el sur por los propios linderos patrios.

    La ciudad también tiene una historia de hospitales, de clínicas, de farmacias, de enfermeras y de galenos ilustres que ocupan un sitial grande en el escenario del esplendor. Por eso el acopio de datos, en libros y recuentos, siempre son bien recibidos porque ellos evitan que las anécdotas no vayan al baúl ominoso del olvido “El libro” Historia de la medicina en Nariño, siglo XX”de los doctores Leonardo Matta y Ricardo Zarama Burbano dice que el primer hospital que existió en la ciudad estaba localizado en lo que es hoy, la carrera 25 con calle 16 y que se llamaba centro de atención de pacientes La Madre de Dios, cuyo director era el doctor Pedro de Ahumada (Hermano de Santa Teresa de Jesús.

El autor concluye que el grupo de 15 a 34 años es el más afectado por las muertes violentas y que las zonas fronterizas y costeras son las que presentan mayor riesgo.Nuestra sección de documentos históricos reproduce un trabajo elaborado hace más de 25 años por Víctor Gómez, catedrático pensionado de la Universidad de Costa Rica.

  18. A Laser Spark Plug Ignition System for a Stationary Lean-Burn Natural Gas Reciprocating Engine

    McIntyre, D. L. [West Virginia Univ., Morgantown, WV (United States)

    2007-05-01

    To meet the ignition system needs of large bore, high pressure, lean burn, natural gas engines a side pumped, passively Q-switched, Nd:YAG laser was developed and tested. The laser was designed to produce the optical intensities needed to initiate ignition in a lean burn, high compression engine. The laser and associated optics were designed with a passive Q-switch to eliminate the need for high voltage signaling and associated equipment. The laser was diode pumped to eliminate the need for high voltage flash lamps which have poor pumping efficiency. The independent and dependent parameters of the laser were identified and explored in specific combinations that produced consistent robust sparks in laboratory air. Prior research has shown that increasing gas pressure lowers the breakdown threshold for laser initiated ignition. The laser has an overall geometry of 57x57x152 mm with an output beam diameter of approximately 3 mm. The experimentation used a wide range of optical and electrical input parameters that when combined produced ignition in laboratory air. The results show a strong dependence of the output parameters on the output coupler reflectivity, Q-switch initial transmission, and gain media dopant concentration. As these three parameters were lowered the output performance of the laser increased leading to larger more brilliant sparks. The results show peak power levels of up to 3MW and peak focal intensities of up to 560 GW/cm2. Engine testing was performed on a Ricardo Proteus single cylinder research engine. The goal of the engine testing was to show that the test laser performs identically to the commercially available flashlamp pumped actively Q-switched laser used in previous laser ignition testing. The engine testing consisted of a comparison of the in-cylinder, and emissions behavior of the engine using each of the lasers as an ignition system. All engine parameters were kept as constant as possilbe while the equivalence ratio (fueling

    Full Text Available Este ensayo del sabio conservacionista Henri Pittier (1857-1950 que data de 1904 es posiblemente el primer testimonio sobre la excepcional longevidad de los habitantes de la Península de Nicoya, Costa Rica. Fue el estadístico costarricense Carlos Raabe quien llamó mi atención sobre este ensayo cuando en 2007 diversos medios de comunicación del mundo dan a conocer a la, así llamada, “Blue Zone” de Nicoya. La organización National Geographic había acuñado tres años antes en un artículo de su conocida revista el término Blue Zone para designar tres bolsones de súper longevidad en el mundo: Okinawa en Japón, Cerdeña en Italia y Loma Linda en California, EEUU. Más tarde, y a raíz de una ponencia sobre la excepcionalmente baja mortalidad de los nonagenarios costarricenses que presenté en la XXV Conferencia Mundial de la Unión Internacional para el Estudio Científico de la Población (IUSSP en Tours, Francia y tras cuidadoso examen de la evidencia científica, National Geographic incluye a la península de Nicoya como la cuarta Blue Zone del mundo. Henri Pittier se anticipa, entonces, cien años en descubrir la Blue Zone de Nicoya.¿Quién es Henri Pittier?Una rápida búsqueda en Google da cuenta de que el más antiguo y más famoso parque nacional de Venezuela, establecido en 1938, se denomina Henri Pittier en reconocimiento al botánico y geógrafo suizo de ese nombre que se estableció en ese país en 1917 y que publicó en 1926 el “Manual de las Plantas Usuales de Venezuela” una obra clásica reeditada varias veces y utilizada hasta nuestros días. Pittier publicó cerca de 300 obras, entre los que se cuenta otra obra clásica: “Primitia Flora Costaricensis” (1907. Henri Pittier es de la estirpe de los sabios naturalistas del Siglo XIX como Humboldt o Darwin.

    escritos de Carrasquilla refutando las espeluznantes descripciones de la enfermedad que hacían Emilia Pardo Bazan en Europa y el doctor Ricardo de la Parra entre nosotros. Sus artículos sobre las manifestaciones clínicas de la lepra, publicados en 1905 en los Anales de la Academia de Medellín, son “clásicos por la excelencia de su estilo y la sobriedad y precisión de los conceptos expresados en ellos”, escribe De Francisco.

    La vida de Carrasquilla estuvo marcada por triunfos, pero también sinsabores. El gobierno del Presidente Caro creó en 1895 el Instituto Carrasquilla para el estudio y el tratamiento de la enfermedad bajo la dirección de Juan de Dios Carrasquilla. Allí se desarrolló una importante labor científica no sólo en lepra sino en otros campos. Pero a finales de 1897, cuando Carrasquilla presentaba sus estudios en la Conferencia Internacional de Berlín, el gobierno de Caro clausuró el Instituto.

    El doctor Juan de Dios Carrasquilla falleció a los 75 años de edad, el 14 de julio de 1908. En medio de la consternación de la ciudadanía, sus exequias se realizaron el día siguiente. El doctor Luis Zea Uribe pronunció la oración fúnebre. Adolfo De Francisco Zea reproduce las palabras de Zea Uribe que “retratan de manera admirable la noble figura del sabio”. También transcribe De Francisco la conferencia pronunciada en 1923 en el Teatro Colón de Bogotá, por el doctor Luis Zea Uribe en favor de los leprosos de Agua de Dios: “Juan de Dios Carrasquilla es una de las más limpias glorias de la patria… La patria colombiana teje la más pura corona de su gratitud y de su admiración sobre las sienes del modesto sabio, que fue un gran patriota y un corazón excelente”...

    Grata es la presencia de vosotros, socios, colegas y amigos, que habéis tenido la gentileza de acompañarnos en este día para nosotros tan lleno de satisfacciones y hondos recuerdos.

    Con orgullo patriótico, celebramos hoy 90 años de la fundación de nuestra institución y ello por sí sólo es motivo suficiente para rendir justo tributo de admiración y cariño a nuestros mayores, quienes en desigual y desinteresada lucha, inspirados eso sí en nobles ideales, acometieron con arrojo esta empresa de dotar a la ciudad y al país de un centro hospitalario que hoy alcanza, después de tan largos años de arduo trabajo, proporciones de innegable valor y sitio prominente en la trayectoria de las realizaciones.

    Ha sido nuestra contribución, franca, leal y sincera en la lucha contra la enfermedad, el dolor y el desconsuelo.

    A comienzos del siglo XX, Chapinero era un barrio campestre de la capital, en su extremo norte, constituido por grandes casaquintas destinadas especialmente para el descanso familiar.

    Una de las más bellas, la había construido el francés Arturo A. de Cambill, luego de comprarle la quinta La Rosita a don Ricardo Gaviria en 1891. Cambill levantó una amplia y hermosa casa y embelleció el lugar con jardín, huertos y otros atractivos de tipo europeo.

    En recuerdo del sitio veraniego de Luis XIV, la llamó Marly. Cambill, le vendió su casa a John M. Vaughan en 1896 quien a su vez, e131 de mayo de 1901, vendió al odontólogo Guillermo Esguerra dicha propiedad. Guillermo Esguerra graduado en los Estados Unidos y hombre emprendedor, amplió las edificaciones y embelleció la casa y se radicó allí con su familia.

    Por ese entonces, regresó de Europa su hermano mayor, el médico Carlos Esguerra. El nombre del doctor Carlos E82,”‘lerraGaitán, cuya fecha de nacimiento se anota el 14 de diciembre de 1863, llena por sí sólo una interesantísima página de la historia médica nacional

Nor was her formal education in astronomy quite complete, for during that difficult period she completed writing her dissertation and earned a PhD in astronomy from Ege University in 1982. AAVSO's headquarters on Concord Avenue was increasingly crowded and also insecure, as the historical data were stored in a building that was vulnerable to fire. In August 1985 long-term AAVSO secretary and benefactor Clinton Banker Ford (BAAS, 1994:1602) solved these problems by donating a new headquarters building at 25 Birch Street in Cambridge. Janet managed the move into the AAVSO's present facilities masterfully, and then led planning for a dedication of the building combined with a celebration of the AAVSO's seventy-fifth anniversary. It is a measure of Janet's growth in stature in the professional community that Ricardo Giacconi, then director of the Space Telescope Science Institute, was the keynote speaker for the celebration and it was attended by the leaders of variable star organizations from a number of countries. The meeting marked a major turning point in the affairs of AAVSO as well as in Janet's own outlook. Substantially more confident in her abilities as a manager and leader of the organization, Janet never looked back. Janet's international contacts, through her active participation in the International Astronomical Union (IAU), led her to participate in 1987 as one of the organizers of an IAU colloquium in Paris on the contribution of amateurs to astronomy, the first of her many later involvements in the field of professional-amateur (Pro-Am) cooperation. During that meeting, the Sociétié Astronomique de France (SAF) honored Janet with their Centennial Award for her leadership in variable star astronomy and within the AAVSO. She received an invitation from the Vereniging voor Sterrenkunde, the variable star observers

The second part proceeds with the reconstruction of literary historiography as a discipline, using a large series of paradigms, which are either fundamental to the great fields inherited or characterize the extremes and singularities. It begins with "La evolución de la historiografía literaria clásica" by José Joaquín Caerols; "Una síntesis de la historiografía patrística" by Fernando Rivas; "Historiografía de la traducción", a chapter shared by Francisco Lafarga and Luis Pegenaute; "La historiografía estética: pasado y presente", completely realised for the first time by Vicente Carreres; " Introducción a la ‘Historia de la Ciencia’ como género " by Javier Hernandez Ariza; "Musicología histórica e historiografía" by Teresa Cascudo; "La historiografía artística: las artes plásticas" by Javier Portús; and "Historiografía y cine" by José Carlos Rueda.        The third part addresses the opening up to the Middle East, Asia, Africa and America, trying to interpretively characterize and to reconstruct, selectively, the horizon of literary historiographies as large fields, without losing sight of the comparative sense, intended to set up a sense of universality as a way of overcoming the national divisions and restrictions. All this is addresssed in chapters by Ana Agud, "Una historiografía difícil: India"; "El estudio comparatista de la historia literaria de Asia del Este según Cho Dong-Il", prepared by Lee Hye-Kyung; by Alfonso Falero, "Hacia una historiografía literaria en Japón"; by Isaac Donoso, "Historiografía de las letras filipinas".

    renewal, the haggling around the competition for the House of Representatives or the rivalry and troubles around the The Hague City Hall? The Eurojust (The European Union’s Judicial Cooperation Unit? The International Criminal Court? Such stormy conflicts arise and no sooner ebb away again, often into silent oblivion. And still, in most cases, the construction of the urban image is executed as planned, though often partially. Even more, the conflicts are of importance because they reveal how people experience the city and want to see it. Cracks in society are bluntly exposed this way. For example, the most monumental gateway in The Hague is that of the The Hague Police Precinct built in the 1950’s, which faces the rear side of The Hague’s progressive party’s flagship (1986-1989, the residential complex designed by Ricardo Bofill with parking access, garbage containers, and other utilities. A good observer can see the many contradictions of society mirrored in this situation in the city. The object of this study is to examine the image of the city and the conflicts pertaining to it. The image of the city, also referred to here as the city image, has become particularly popular in recent years. This is due in part to the new position of cities in the global urbanization process, whereby cities have become competitors and moreover, new opportunities for cities to present themselves worldwide result from the revolution in communication technology and digitization. The research shows that the city image, despite its elusiveness and fluidity, played an imperative role in the genesis of the city far earlier. Churchill’s statement ‘we formed our cities and the cities formed us’ could be broadened to: ‘we imagined our cities and that image formed us.’ Nancy Stieber (2006 gave in the book de STAD (2006 an insightful analysis on the relationship between images and the city. The city is conceptualized as a metaphor. According to her, that is one of the

Reviewed by Ricardo Romo TORRES Manuel Moreno Castaneda Maria del Sol Orozco Aguirre Universidad de Guadalajara Virtual MEXICO http://www.udgvirtual.udg.mx "On-line Education " is a book that meets the challenge to present itself as an unfinished text. In addition to demanding an active participation of the reader, it requires a predisposition to complete it through an also inconclusive dialogue. Among its goals we can find the search for education networks that remain under constant reconstruction, maintaining the emancipative vision as an imperative for the reconfiguration, as a constituted tissue for the scaffolding of subjects who impress,imagine, think and have a will. The unfinished part is presented in the following paragraph: "Similar to Babel according to Borges, knowledge is the product of a hazard in which fiction is the universe and where, out of fear of its multiple combinations, individual texts constitute an unfinished tale. In this labyrinth-shaped universe, the mirror and the recurrence do not allow finding the way out" page 134. The sense of being of man within a planetary community is framed by the ontological condition of conclusiveness; the requirement of being more, however, as well. This more is guided by the need for dialogue with others in terms of the opening and maintaining an unconcluded dialogue. The idea of a web or network leads to an articulating demand within the context of the category of wholeness. Based on this category, we will be able to present a reticulum of concepts where we can find included the web, subjectivity, identity, experience, mediation and, of course, digital literacy. This reticulum results in a concept of identified education with a condensed arrival point to something that the author defines as 'the pedagogy of virtuality'. The author is

    autores recorrem a uma documentação variada e oferecem informações detalhadas de uma diversidade de aspectos dessa modalidade educativa: materialidade, currículos, metodologias de ensino, população estudantil.Bruno Bontempi Jr, na sequencia, volta-se à Escola Politécnica de São Paulo e aos engenheiros paulistas formados pela instituição. Memórias, identidades e representações sociais entorno à profissão e à instituição são examinadas a partir da análise dos discursos de engenheiros e formandos, proferidos em sessões solenes da instituição entre 1899 e 1910. O autor afirma que essas instituições de ensino superior constituíram espaços de formação e sociabilidades e, de certa forma, as cerimônias de colação de grau são emblemáticas a esse respeito, não apenas pela ritualística altamente simbólica, mas também como momentos de visibilidade e proliferação discursiva das identidades e representações sociais internamente cultivadas e que se almejava legitimar socialmente.Para fechar este número, História da Educação oferece a seus leitores um documento precioso e uma resenha de obra fundamental. O documento é generosamente partilhado por Eduardo Arriada, Elomar Antonio Callegaro Tambara e Sheila Duarte e intitula-se A sciencia do bom homem Ricardo, titulo que os pesquisadores acrescem o oportuno complemento: um texto de leitura escolar no Brasil Imperial. Recorrentemente, nos eventos e nos balanços da produção em História da educação, vimos nos ressentindo do número de estudos e documentação lacunar acerca do período imperial.Eis um contributo que se soma aos demais já publicados pela revista para conhecimento dos pesquisadores da área.
