    Directory of Open Access Journals (Sweden)

    Lucena, Karina de Castilhos

    2014-01-01

    Full Text Available Este artigo analisa as cartas enviadas pelo escritor uruguaio Juan Carlos Onetti (1909- 1994 ao crítico de arte argentino Julio Payró (1899-1971 entre 1937 e 1955. A análise desses documentos contradiz uma faceta generalizante presente na fortuna crítica do autor, que o descreve como homem solitário e frio. Nos textos aqui estudados, Onetti manifesta seu carinho e admiração por Payró. Da mesma forma, as cartas oferecem dados que contestam a imagem do Onetti descompromissado, já que ele demonstra preocupação com os rumos da política de seu país. A correspondência também revela inseguranças e vaidades que a figura pública fazia questão de manter escondidas. Nesse sentido, este trabalho sugere que investigações a partir de documentos pessoais de escritores podem ampliar fortemente a interpretação de sua obra e às vezes se opor a juízos estabelecidos pelos críticos que não tiveram acesso a esse material.

  9. Modern Monarchs and Democracy: Thailand’s Bhumibol Adulyadej and Juan Carlos of Spain

    Directory of Open Access Journals (Sweden)

    Serhat Ünaldi

    2012-01-01

    Full Text Available The history of democracy is typically a history of struggle against monarchs and other such autocrats. The elevation of one person over others by virtue of blood and birth has come to be seen as anachronistic; yet some monarchies have managed to survive to this day. This paper analyses two examples of the uneasy coalition between popular sovereignty and royal leadership that is constitutional monarchy. Whereas Juan Carlos of Spain has been described as having steered Spain away from dictatorship, Bhumibol of Thailand has come under scrutiny for allegedly lacking a principled approach to democracy. I argue that structural as much as personal factors influenced the ways in which the two monarchies were legitimised – one by positively responding to the modern aspirations of the king’s subjects, giving him a “forward legitimacy,” the other by revitalising the king’s traditional charisma and opting for “backward legitimacy.”

  10. Juan Carlos Rodríguez y la renovación de marxismo althusseriano

    Directory of Open Access Journals (Sweden)

    Malcolm K. Read

    2013-06-01

    Full Text Available In the immediate aftermath of 1968, a number of works on Marxist literary theory appeared that were destined to command the attention not only of writers who were re- cognizably ‘Marxist’ or ‘Marxian’ but of others who boasted little in the way of allegiance to the Marxist tradition, however broadly defined. Two such works were Terry Eagleton’s Criticism and Ideology (1976 and Fredric Jameson’s The Political Unconscious (1981. While deeply and confessedly indebted to Louis Althusser for kick-starting their careers, inspirationally speaking, both Eagleton and Jameson were subsequently to reveal an ambiguous, even troubled relation to the French Marxist: Eagleton, through a series of texts that, their unquestionable distinction notwithstanding, run hot and cold in their commitment to ‘Althusserianism’; Jameson, through a brand of Hegelianizing Marxism that finally proved unable to take on board the full complexity of the Althusserian legacy. Preceding both these scholars chronologically, and bearing comparison with them in terms of intellectual range, ambition, and productivity, was Juan Carlos Rodríguez, whose Teoría e historia de la producción ideológica appeared in 1974. Except that there the similarities end, for whereas Eagleton and Jameson were destined to achieve star status within their profession, a rather different career trajectory awaited Rodríguez.

  11. Cultural Words in Slovenian Translations of the Works of Juan Rulfo and Carlos Fuentes

    Directory of Open Access Journals (Sweden)

    Uršula Kastelic Vukadinović

    2016-12-01

    Full Text Available The paper, based on the author´s thesis entitled Kulturno besedje v slovenskih prevodih del Juana Rulfa in Carlosa Fuentesa, discusses cultural words in the Slovenian translations of the novel Pedro Páramo, some of the stories of The Plain in Flames by Juan Rulfo published in the same volume and the novel The Death of Artemio Cruz by Carlos Fuentes. In the analyzed texts there are a number of terms (also including cultural words which denote animals, plants, dishes, clothes and geographical surroundings of Mexico that may be unknown even to the Spanish speaking readers who are not familiar with the wider Hispanic environment, and Mexican in particular. Cultural words have no exact equivalents in other languages and cultures, therefore, they most commonly indicate that we are reading a translated text. These are also the elements that contribute to the foreignization of the target text and show us the textual world as exotic and unknown. The translator of the studied texts, Alenka Bole Vrabec, tends to choose the transfer of the cultural words in order to retain some local colour, even when she could find equivalents in the Slovenian or, at least, adapt the words to the writing in accordance with the rules of the Slovenian language. These decisions accentuate the foreignizing character of her translations.

    Full Text Available La obra de Juan Carlos Onetti se caracteriza por plantear a partir de un complejo manejo de las voces del narrador ficticio -hablante en primera, tercera persona o un colectivo “nosotros”- la crisis y el desdoblamiento de la identidad del hombre contemporáneo, encarnado en los personajes marginales o marginalizados que pueblan su narrativa. Centrado en sus novelas cortas, este ensayo analiza como Onetti esfumina los límites de la tipología tradicional del narrador y traza nuevas y sinuosas fronterasJuan Carlos Onetti´s work is characterized by setting forth a crisis and an unfolding of the identity of today´s man, from an elaborate use of the fictitious narrator´s voices, in the first person, third person, and a collective first person plural. Today´s man is represented by impoverished and subjected characters that fill up the author´s novel. Mainly focused on the author´s short stories, this essay attempts to analyze how Onetti extends the boundaries of the narrator´s traditional typology, and builds up new sinuous borders

  17. What We Talk about When We Talk about Ideology: a critical approach to Juan Carlos Rodríguez's theory of Ideological Unconscious

    Directory of Open Access Journals (Sweden)

    Chiara Giordano

    2015-11-01

    Full Text Available Scopo del presente articolo è riflettere sul concetto di “inconscio ideologico” come via di analisi del testo letterario e, più in generale, della prassi artistica considerata nel suo inestricabile rapporto con il contesto ideologico. Alla base del pensiero critico di Juan Carlos Rodríguez Gómez – attualmente una delle figure più rilevanti della teoria letteraria marxista in ambito spagnolo –, tale nozione nasce dall’attenta e riconoscente lettura dell’opera di Louis Althusser ed è trasversale a tutte le opere del filologo granadino. Con il proposito di offrire un’approssimazione analitica e una valutazione critica del concetto di “inconscio ideologico”, l’orizzonte teorico di Juan Carlos Rodríguez sarà dunque messo a confronto con una serie di concetti affini (dalla definizione althusseriana di ideologia all’ideologia “immaginaria” di Terry Eagleton e al jamesoniano “inconscio politico” che ci aiuteranno a situarlo all’interno della critica dell’ideologia. Come si cercherà di dimostrare nel corso dell’articolo, Juan Carlos Rodríguez recupera ed approfondisce l’incontro tra marxismo e psicoanalisi inaugurato nel 1964 da Althusser e risponde con originalità alle nuove sfide della critica letteraria marxista.

    Full Text Available Universities should contribute to promoting and increasing values that allow wellbeing, independence and the full development of their students and staff. The Universidad Rey Juan Carlos through the Office for Social Politics, Environmental Quality and Healthy University (Vicerrectorado de Política Social, Calidad Ambiental y Universidad Saludable offers a program for Promotion of Health and Wellbeing (Programa de Promoción de la Salud y Bienestar for the entire university community. The following article describes the initiatives that 181 volunteers participated in, either in individual or group settings for 8 sessions depending on their self-detected individual needs. Results show significant pre-post developments in four of the self-assessed variables: self-efficacy, positive and negative affect, and self-esteem. These developments were maintained throughout follow-up. No differences were found based on gender or group, but differences were found in affect depending on the type of therapy followed (individual vs. group. The practical implications of this initiative are highlighted as a way to promote health and wellbeing in a university context.

  19. Influencia de William Faulkner en Juan Carlos Onetti con referencia a la fe, Dios y la carne. Una perspectiva hermenéutica

    Directory of Open Access Journals (Sweden)

    Alberto F. Roldán

    2016-07-01

    Full Text Available In this article some features of the influence of American writer William Faulkner in the narrative of Juan Carlos Onetti’s is analyzed. This work represents a reading on three topics of systematic theology: faith, God and the flesh; as they appear in both authors’ work. In the first part, the theory developed by the Mexican Carlos Fuentes is taken as a framework of analysis that explores the three reasons why the authors of the Latin American boom adopted Faulkner’s narrative style: the myth of the fictional place, defeat and circular time as a way of eternal return. In the second one, examples of Faulkner’s influence in several authors of the so-called Latin American boom are offered, with a special reference of Juan Carlos Onetti’s. The work focuses on the novels La vida breve and El Astillero of Onetti’s and Absalom, Absalom! Of Faulkner’s. In the conclusions, we reflect on the way the issues of faith, God and the flesh are presented in the narrative of both authors, the kind of theology they reflect - Catholic or Protestant- and their points of convergence and divergence. Anhermeneutical methodology has been chosen.

    2014-01-01

    The Germplasm Bank of Universidad Rey Juan Carlos was created in 2008 and currently holds 235 accessions and 96 species. This bank focuses on the conservation of wild-plant communities and aims to conserve ex situ a representative sample of the plant biodiversity present in a habitat, emphasizing priority ecosystems identified by the Habitats Directive. It is also used to store plant material for research and teaching purposes. The collection consists of three subcollections, two representative of typical habitats in the center of the Iberian Peninsula: high-mountain pastures (psicroxerophylous pastures) and semi-arid habitats (gypsophylic steppes), and a third representative of the genus Lupinus. The high-mountain subcollection currently holds 153 accessions (63 species), the semi-arid subcollection has 76 accessions (29 species,) and the Lupinus subcollection has 6 accessions (4 species). All accessions are stored in a freezer at -18 °C in Kilner jars with silica gel. The Germplasm Bank of Universidad Rey Juan Carlos follows a quality control protocol which describes the workflow performed with seeds from seed collection to storage. All collectors are members of research groups with great experience in species identification. Herbarium specimens associated with seed accessions are preserved and 63% of the records have been georreferenced with GPS and radio points. The dataset provides unique information concerning the location of populations of plant species that form part of the psicroxerophylous pastures and gypsophylic steppes of Central Spain as well as populations of genus Lupinus in the Iberian Peninsula. It also provides relevant information concerning mean seed weight and seed germination values under specific incubation conditions. This dataset has already been used by researchers of the Area of Biodiversity and Conservation of URJC as a source of information for the design and implementation of experimental designs in these plant communities.

    Full Text Available In the actual neo-colonialist configuration, there seems to be an imposed philosophical vision and hermeneutic that is fundamental for the political and socio-economical neo-colonialist structure. The thought-action and hermeneuticpraxis bond is here analyzed from the philosophical stand point of Maurice Blondel and Juan Carlos Scannone in relation to the neo-colonialist sociocultural, political and economical configurations and strategies. The question of “development” and “civilisation” should be rediscussed in relation to financial economy and not anymore with an apparently moral will of changing the real economy of the colonized countries, since these concepts are the actual instruments of the financial economy. According to Scannone, from the exportation of “democracy” to the exploitation of the Other, a moral and historic-philosophical analysis seems to be needed today.

  5. NREL Response to the Report 'Study of the Effects on Employment of Public Aid to Renewable Energy Sources' from King Juan Carlos University (Spain) (White Paper)

    Energy Technology Data Exchange (ETDEWEB)

    Lantz, E.; Tegen, S.

    2009-08-01

    Job generation has been a part of the national dialogue surrounding energy policy and renewable energy (RE) for many years. RE advocates tout the ability of renewable energy to support new job opportunities in rural America and the manufacturing sector. Others argue that spending on renewable energy is an inefficient allocation of resources and can result in job losses in the broader economy. The report, Study of the Effects on Employment of Public Aid to Renewable Energy Sources, from King Juan Carlos University in Spain, is one recent addition to this debate. This report asserts that, on average, every renewable energy job in Spain 'destroyed' 2.2 jobs in the broader Spanish economy. The authors also apply this ratio to the U.S. context to estimate expected job loss from renewable energy development and policy in the United States. This memo discusses fundamental and technical limitations of the analysis by King Juan Carlos University and notes critical assumptions implicit in the ultimate conclusions of their work. The memo also includes a review of traditional employment impact analyses that rely on accepted, peer-reviewed methodologies, and it highlights specific variables that can significantly influence the results of traditional employment impact analysis.

    Full Text Available Desde la teoría de los Usos y Gratificaciones, el objetivo de este trabajo es comparar los hábitos y razones del consumo televisivo juvenil en la pantalla tradicional y en el ordenador. A partir de una encuesta aplicada a una muestra de 213 estudiantes de primero a tercero de titulaciones de grado de ciencias sociales de la Universidad Rey Juan Carlos, se analizarán sus hábitos de consumo en los dos soportes, se examinarán cuáles sus formatos televisivos preferidos así como sus motivos de exposición para conocer cuál es el soporte que les proporciona una mayor gratificación. Entre los principales resultados hallados se destaca que la televisión convencional continúa siendo el medio preferido para una generación que, todavía, no ha culminado la transición hacia el medio digital y que el consumo se realiza de manera individual en los dos tipos de soportes analizados. Son individuos que realizan un consumo televisivo multitarea y en los que el visionado no les resta tiempo a la realización de otro tipo de actividades. Se inclinan hacia la televisión por Internet por sus características más que por su oferta y hacia la televisión convencional porque quieren entretenerse, informarse y aprender.

    Full Text Available Durante la Edad Moderna y Contemporánea numerosos retos se han abordado, de manera ideal o real, desde una perspectiva cosmopolita. El descubrimiento de América, las guerras entre Estados europeos en el siglo XVIII o la Segunda Guerra Mundial, son ejemplos de ello. En la época actual, la humanidad se enfrenta también a una serie de retos globales de gran magnitud: el mantenimiento de la paz, el respeto y garantía de los derechos humanos, el cambio climático, las migraciones internacionales, el aumento de la desigualdad, las pandemias, el terrorismo, los paraísos fiscales o el colapso de los sistemas financieros. La nueva obra de Juan Carlos Velasco busca precisamente abordar con carácter descriptivo, valorativo y normativo uno de esos retos, las migraciones internacionales, y adopta para ello una mirada cosmopolita.

Sparkman Center for International Public Health Education and later the dean of UAB School of Public Health watched him train and shape the next generation of global public health leaders with a kind heart and a firm, but gentle, hand. On this third anniversary of Professor Navia's passing, in response to an invitation from the Journal of Dental Research to write an essay on an educator who influenced the professional trajectories of many people, we have put together an account of some of his contributions and attributes to highlight this remarkable leader's accomplishments in and impact on dental public health and global nutrition.

    Full Text Available Juan Marichal nació en Santa Cruz de Tenerife, en 1922, en el seno de una familia ligada al partido republicano insular. Muy joven, en 1935, se trasladó a Madrid, ciudad en la que vive el estallido de la guerra civil. En 1937, pasa a Valencia y luego a Barcelona; tras su exilio en 1938, prosigue sus estudios secundarios en un liceo de París, concluyéndolos en Casablanca. En 1941 emigra a México, formándose en la UNAM: fue alumno de los exiliados José Gaos y Joaquín Xirau así como del mexicano Edmundo O 'Gorman. Luego, becado en Princeton desde 1946, lo fue de América Castro, donde preparó una tesis sobre Feijoo. Apoyado en las vastas perspectivas de sus maestros, fue orientándose hada nuestra historia intelectual, desde el siglo XV hasta hoy. Su carrera profesional se ha desarrollado en los Estados Unidos (coincidiendo con Amado Alonso y con Ferrater Mora: ha sido profesor de estudios hispánicos en la Universidad de Harvard, desde 1948 hasta 1988, año en que se jubiló voluntariamente como numerario (aunque había permanecido en el Bryn Mawr College, entre 1953 y 1957. A este trabajo se suman, con todo, sus conferencias en América Latina y en España. Ha colaborado en las revistas más importantes, en este campo, de México, Nueva York, Puerto Rico, La Habana, Buenos Aires o París así como de las españolas, desde los sesenta. Juan Marichal -hoy, miembro de la Junta Directiva de los Amigos de la Residencia de Estudiantes, director del Boletín de la Institución Libre de Enseñanza y asociado al Instituto Universitario Ortega y Gasset-, reside en España desde otoño de 1989: se considera a sí mismo «voluntario en Madrid», como había dicho Alfonso Reyes en su estancia madrileña (1914-1924.

    1997-09-01

    Full Text Available Not available.Dos hilos impulsan estas líneas: la reflexión sobre uno de los acontecimientos cruciales de este fin de siglo en Europa, la masacre de Srebrenica, y la necesidad de contribuir a la tarea colectiva de reconstruir una tradición filosófica en lengua castellana más allá de las clásicas distinciones de géneros. Ambos propósitos confluirían, metonímica y metafóricamente, en un nombre, Machado, y una obra, el Juan de Mairena. Los textos del apócrifo del poeta, tan próximo en algunos momentos al pensamiento de Lévinas o Heidegger, pueden contribuir a articular un examen crítico, insertado en una tradición, sobre ese símbolo de nuestra época.

    Full Text Available Since Tormo, Gusi and Lafuente wrote fray Juan Rizi's monograph in 1930, and Ángulo & Pérez Sánchez revised years later this study in their book Pintura madrileña del segundo tercio del siglo XVII, very little has been published about the life and work of the Benedictine painter. Furthermore, the Italian journey of Rizi, that involved the last 20 years of his life, has always been an enigma, resolved only in certain aspects, thanks to few news supplied by his biographers and the manuscripts the monk wrote during his staying in the Montecassino abbey. Our recent discovery of 8 new canvases painted by Rizi to decorate the Saints Cosme and Damian's chapel in the main church of Trevi nel Lazio (Frosinone, Italy, as well as the location of several new drawings in the Montecassino and Vatican libraries, will allow us to study his activity as painter in Italy and also to profile, with more accuracy, the history of the last years of his life.No disponible

  10. La actuación política de don Juan de Borbón ante el fallecimiento de Franco

    Directory of Open Access Journals (Sweden)

    Jaime Cosgaya García

    2005-01-01

    Full Text Available La designación de don Juan Carlos en julio de 1969 como sucesor en la jefatura del Estado, a título de Rey, modificó sustancialmente las relaciones que hasta entonces habían mantenido Franco y don Juan, y colocó en una nueva situación a padre e hijo, situados a partir de ese instante en posiciones políticas diversas y en cierto modo contrarias. Sin embargo, la actuación política que desarrolló don Juan de Borbón desde ese momento hasta el fallecimiento de Franco, fue la de un colaborador discreto y eficaz de su hijo. Esta comunicación estudia dos proyectos que demuestran esta línea de comportamiento del conde de Barcelona. Ambos se originaron ante la proximidad del fallecimiento de Franco y tuvieron como punto en común la participación de Antonio Fontán. El primer encargo fue la redacción de una posible declaración a la muerte del general en julio de 1974, que finalmente no se hizo pública; y el segundo consistió en la mediación de esta personalidad monárquica para manifestar a don Juan Carlos —a los pocos días de ser proclamado Rey— su intención de renunciar a los derechos dinásticos de los que era depositario por el testamento de Alfonso XIII.The appointment of don Juan Carlos in July 1969 as forthcoming Head of State — King of Spain— changed dramatically the relationship between Franco and Don Juan. On the other hand, a new relationship between father and son appeared and, thereinafter, they will hold different —and, to some extent— conflicting political positions. Nevertheless, Don Juan de Borbón from that moment until to Franco’s death played the role of a discreet and effective assistant. This paper studies two facts within this political behaviour of Barcelona’s Count. Both of them stemmed from the possible death of Franco, playing Antonio Fontán a prominent role in both of them. The first task was a possible speech after Franco’s death in July 1974 which was not finally published. The second

Le poids fiscal s’exerce durement sur le village et la crise est générale dans toute la vallée du Chancay au XVIIe. siècle. La christianisation des habitants est définitive au milieu de ce même siècle. C’est vers la fin du XVIIe siècle et durant tout le XVIIIe que se multiplient les conflits entre San Juan et les villages voisins liés aux terrains de pâture et à la possession de l’eau. La deuxième partie du travail concerne les rapports de la communauté de San Juan avec le Pérou contemporain : contrainte fiscale toujours très lourde durant la fin de l’époque coloniale, exactions des militaires juste avant l’indépendance. La période républicaine voit toujours les conflits avec les villages voisins mais aussi la naissance de familles qui cherchent à retirer le maximum de la communauté. Les terres sont divisées et attribuées : la détérioration de l’organisation communale traditionnelle est manifeste. L4es conflits se multiplient entre petits propriétaires, mais aussi avec les haciendas voisines : c’est l’apparition d’une véritable lutte de classes.

    Full Text Available From the analysis of a few comic devices of the absurd in Don Juan Tenorio «El refugiao» —a parodical play by exiled playwright Juan Mateu, first performed in Toulouse in 1958—, this article aims at showing that a tradition is still alive —a tradition that can, non only be traced back to La venganza de don Mendo by Muñoz Seca (who did not, as has been claimed, invent the theatre of the absurd, but which is also part of an old trend stemming from Juan del Encina's famous Disparates, which has been exemplified by the burlesque plays of the seventeenth century, which was obvious in the nineteenth and early twentieth century popular liking for parodical drama, and which is still today one of the sources of what could be called humour the Spanish way.A partir del análisis de algunos mecanismos cómicos del absurdo en Don Juan Tenorio «El refugiao» —obra paródica del dramaturgo exiliado Juan Mateu estrenada en Toulouse en 1958—, el artículo pretende demostrar la persistencia de una tradición que no se remonta sólo a La venganza de don Mendo de Muñoz Seca (el cual no fue ni mucho menos, como demasiadas veces se ha dicho, el inventor del teatro del absurdo, sino que se inscribe en una vieja trayectoria arraigada en los famosos Disparates de Juan del Encina, ilustrada luego por la comedia burlesca del siglo XVII, patente en la afición popular del XIX y principios del XX al teatro paródico y que todavía hoy es una de las fuentes de lo que se podría llamar un humor «a la española».

  7. An Inquiry into Juan Ramon's Interest in Walter Pater

    Directory of Open Access Journals (Sweden)

    John C. Wilcox

    1983-01-01

    Full Text Available The evidence for Juan Ramon's interest in Pater, which began around 1920 and was still active twenty years later, is discussed in this paper. Pater's view of death and dying and his attitude toward the decadent persona are described in so far as they indicate the spiritual affinity that exists between him and Juan Ramón. Pater's aesthetic idealism, and the presence of similar ideals in Juan Ramon's own work are then examined. The second part of the paper concentrates on the great interest Juan Ramón took in Pater's evocation of the Mona Lisa. The potential impact of the aesthetic idealism inherent in this passage, its Platonism in particular, receives special analysis in the light of Espacio , and in consideration of Juan Ramon's 1943 remark: "I am, have been, and always will be a Platonist."

    2015-08-01

    Full Text Available Meteorological factors influence dengue virus ecology by modulating vector mosquito population dynamics, viral replication, and transmission. Dynamic modeling techniques can be used to examine how interactions among meteorological variables, vectors and the dengue virus influence transmission. We developed a dengue fever simulation model by coupling a dynamic simulation model for Aedes aegypti, the primary mosquito vector for dengue, with a basic epidemiological Susceptible-Exposed-Infectious-Recovered (SEIR model. Employing a Monte Carlo approach, we simulated dengue transmission during the period of 2010-2013 in San Juan, PR, where dengue fever is endemic. The results of 9600 simulations using varied model parameters were evaluated by statistical comparison (r2 with surveillance data of dengue cases reported to the Centers for Disease Control and Prevention. To identify the most influential parameters associated with dengue virus transmission for each period the top 1% of best-fit model simulations were retained and compared. Using the top simulations, dengue cases were simulated well for 2010 (r2 = 0.90, p = 0.03, 2011 (r2 = 0.83, p = 0.05, and 2012 (r2 = 0.94, p = 0.01; however, simulations were weaker for 2013 (r2 = 0.25, p = 0.25 and the entire four-year period (r2 = 0.44, p = 0.002. Analysis of parameter values from retained simulations revealed that rain dependent container habitats were more prevalent in best-fitting simulations during the wetter 2010 and 2011 years, while human managed (i.e. manually filled container habitats were more prevalent in best-fitting simulations during the drier 2012 and 2013 years. The simulations further indicate that rainfall strongly modulates the timing of dengue (e.g., epidemics occurred earlier during rainy years while temperature modulates the annual number of dengue fever cases. Our results suggest that meteorological factors have a time-variable influence on dengue transmission relative to other

    2003-10-01

    Hurricane Juan hit the Halifax Regional Municipality on September 28, 2003, creating the largest outage in Nova Scotia Power's history. This detailed report documents the extensive damage that Hurricane Juan caused to the power transmission and distribution system in Nova Scotia. It also reviews the massive power restoration effort, with reference to numerous interviews, computer records and data logs which offer a wide range of observations, statistics and insights into the preparation and performance of Nova Scotia Power Inc. (NSPI) and the efforts of other key organizations following the storm. NSPI organized a recovery effort that matched the intensity of the hurricane. A fire in the Scotia Square Office Tower caused the evacuation of the company's call centre. The Tufts Cove station in Dartmouth, which generates 400 megawatts of power, was forced to shut down. Excess electricity was moved into New Brunswick and other jurisdictions to maintain system stability. The main priority was to restore customers back to service. Within 5 days of the hurricane, 95 per cent of those who lost power had service restored. Hurricane Juan caused the most damage to the transmission and distribution system in NSPI's history. Three out of five high capacity transmission lines were put out of service. Three 120-foot high transmission towers fell, and 17 main transmission lines were damaged and put out of service. Forty-five major substations were affected and 145 distribution feeders were damaged or tripped off, including 106 in the Halifax Regional Municipality. Large portions of 4,500 kilometres of local distribution lines in the Halifax Regional Municipality were damaged, including thousands of kilometers across the Northeast. The power crew, consisting of 2,000 individuals from the region and neighbouring utilities in New Brunswick and Maine, worked for 15 consecutive days to replace 275 transformers, 760 power poles, and 125,000 metres of conductor wire.

    Commercial production from a new formation is rare in a basin as mature as the San Juan. Such a development can be economically attractive because with so many existing wellbores, behind pipe formations can be placed on production quickly and inexpensively. That is happening on the east side of the San Juan, where what appears to be the first significant commercial gas production from Tertiary Ojo Alamo sandstone started last year. The deposit is briefly described.

The study identifies an interpretation of silva as a way of writing different from his predecessor, Pedro Mexía, who first used it to title his work Silva de varia lección twenty years ago. The lack of any intention to arrange its structure gives these silvas the characteristic of a literary draft, a feature derived from one of the meanings of silva inherited from the Classical Age. Moreover, Palmireno’s works reveal an encyclopedic project of which the miscellany (represented by silva forms a part. Furthermore, the silvas of Palmireno act as a transition to the later development of silva as a genre, which finds its educational objective being taken over gradually by the anxiety to provide entertainment.El artículo examina las obras tituladas Silva de Juan Lorenzo Palmireno.

Concluyo señalando que, detrás de dichos temores, es posible leer un anhelo de pertenencia; de aprecio sincero y gratuito, en que no medie el rendimiento académico de la persona; así como un anhelo de seguridad en el entorno cercano.

    Luis Porter Galetar

    2006-05-01

    Full Text Available This article seeks to answer a basic question: Is it possible to include the excluded? We understand the excluded as new social sectors, which are different from those we describe as marginal or exploited.  Rather, these sectors are formed by the large and growing groups of people that contemporary society seems able to ignore. The article starts by analyzing what this new social condition implies to decision makers, and raises new questions.  Do we want to live in a society that excludes 25 or 30% of its more needy population?  Are we capable of learning to live together, as Jacques Delors asks in his UNESCO report?  The ethical dilemma implied by these questions leads to a reflection on the technical-political dimension of inequality in regards to education.  Tedesco and Porter open a dialogue that departs from a macro vision (including the use of new technology and the opening of new fields in educational policies and goes into the micro dimension of specific contexts, from those where people have some educational autonomy and project capacity, to those where people find themselves in situations of anonymity and social dissolution.  Learning to live together implies taking on responsibility for the other, and of knowing the other. In order to break with the social determinism that can lead to fatalist scenarios, it is important to understand that educational success or failure is a systemic phenomenon that depends on a multiple of variables.  Governments have responded to the complexity of the problem with ‘objective’ measures that principally affect the material. In this article we support the idea that an attempt to bring about a greater recognition of the subjective dimension is missing in current educational policy.  To achieve this we identify certain characteristics that various studies have shown as basic requirements to confront the problem: project capacity, narrative capacity and enhanced self-confidence.

Hablo de soledad en el duro campo de la teoría, con independencia de la compañía más o menos numerosa que, con posterioridad, pueda arrastrar un pensamiento distinto como el del maestro. Pero esto ya serían los efectos de ese pensamiento, su continuación o su prolongación en quienes lo leen y no pueden sino quedarse pensativos, no el acto mismo en que el pensamiento es pensado y se arriesga al pensarlo y al escribirlo, y mucho más al publicarlo. Me refiero entonces a ese tipo de soledad advertida por Althusser en el Maquiavelo que teoriza las condiciones políticas de la constitución del Estado nacional, el Maquiavelo que defiende escandalo- samente, contra todas las verdades establecidas en su tiempo, que la lucha de clases es de todo punto indispensable para el reforzamiento y engrandecimiento de ese Estado. Naturalmente, Althusser glosa al Maquiavelo que habla de la soledad del Príncipe: hay que estar solo para fundar un Estado. Esta soledad es aislamiento, pero por ella pasa la libertad: hay que estar solo para ser libre a la hora de cumplir con la tarea histórica de la constitución del Estado. Es decir, y como sigue glosando Althusser (1977: 317, que había que encontrarse, por fortuna y virtud, arrancado radicalmente y sin retorno de las formas políticas de la Italia de entonces, porque todas eran viejas, marcadas por el feudalismo y nada se podía esperar de ellas.

    1973-01-01

    The sequence of mid-Cenozoic volcanic events in the western San Juan Mountains is closely analogous to that elsewhere in the San Juan volcanic field. The Lake Fork, Picayune, and San Juan Formations were erupted from a cluster of central volcanoes from 35 to 30 m.y. ago, when dominant activity shifted to more silicic ash-flow eruptions with accompanying caldera collapses. The Uncompahgre and San Juan calderas, each about 20 km across, formed mainly from eruption of the 28-m.y.-old Sapinero Mesa Tuff. Collapse occurred concurrently with eruption, and intracaldera tuffs accumulated to a thickness of more than 700 m. Both calderas were resurgently domed together; the northeast-trending Eureka graben formed along the distended crest of that dome. The Uncompahgre caldera was then flooded by several 27- to 28-m.y.-old ash-flow sheets from easterly sources, and also by one apparently erupted from the Silverton caldera nested within the older San Juan caldera. The Lake City caldera, located within the older Uncompahgre caldera, formed about 22.5 m.y. ago in response to eruption of the Sunshine Peak Tuff.

    San Juan Coal Company has submitted to the State of New Mexico's Mining and Minerals Division the final phase III bond release application for the approval and release of 241 acres of permitted lands at its San Juan Mine located in San Juan County, New Mexico. The SMCRA (Surface Mining Control and Reclamation Act) and New Mexico Surface Coal Mining Regulations mandate a minimum 10-year liability period following final reclamation, during which no additional treatments other than approved postmining land uses and approved interseedings may be applied to an area for which bond release is sought. Site-specific revegetation success standards must be met for two of the last four years of liability, beginning no sooner than year eight of the bonding period. Successful reclamation of the site was demonstrated by exceeding cover, production, shrub density, and diversity standards while supporting the primary postmining land use of livestock grazing. 11 refs., 1 fig., 8 tabs.

    The MORSE code is a large general-use multigroup Monte Carlo code system. Although no claims can be made regarding its superiority in either theoretical details or Monte Carlo techniques, MORSE has been, since its inception at ORNL in the late 1960s, the most widely used Monte Carlo radiation transport code. The principal reason for this popularity is that MORSE is relatively easy to use, independent of any installation or distribution center, and it can be easily customized to fit almost any specific need. Features of the MORSE code are described.

    Mental health and psychiatric diseases have always attracted people's and health authorities' attention due to its magical approach, the lack of knowledge that surrounds them, and, at the same time, the religious fear they provoke. Both have played an important role in the history of humanity, of public health politics, and of physicians. The places where psychiatric patients were treated are of historical interest, because through the historical knowledge we can identify an approach from the science and the health policies that prevailed in each age. At the beginning of the 20th century, it was developed in México a new model of hospital care attention to psychiatric patients. La Casa de Salud San Juan de Dios para Pacientes Alienados is an example; the concept "alienated patients" suggests a social and cultural perspective. This paper presents a chronological type description of one of the major institutions involved in mental health care in México. Similarly, it shows a review of the events that affected the religious order San Juan de Dios from 1901 to 2012, when the hospitaller order was reinstated in México and established the Casa de Salud San Juan de Dios para Pacientes Alienados in the town of Zapopan, Jalisco, institution that exists up to the present day and keeps participating in the mental health care in the state of Jalisco, with the current name of Servicios de Salud San Juan de Dios.

    Finfish mariculture has existed in the U.S. Pacific Northwest for over thirty years, but for the past 15 years most effort has focused on culture of Atlantic salmon in protected, inshore cage sites. The Strait of Juan de Fuca (the "Strait") is a large area with relatively sparce shoreline development and several apparent advantages for mariculture using offshore technology.

    The concept of Virtual Monte Carlo (VMC) has been developed by the ALICE Software Project to allow different Monte Carlo simulation programs to run without changing the user code, such as the geometry definition, the detector response simulation or input and output formats. Recently, the VMC classes have been integrated into the ROOT framework, and the other relevant packages have been separated from the AliRoot framework and can be used individually by any other HEP project. The general concept of the VMC and its set of base classes provided in ROOT will be presented. Existing implementations for Geant3, Geant4 and FLUKA and simple examples of usage will be described.

    Full Text Available This article is based on an unpublished contract signed in 1539 by Vicente and Juan Macip for an altarpiece for the Valencian Brotherhood of the Blood of Christ. The agreement stipulates that Juan, later known as Juan de Juanes, had to paint the scenes. Thus the document reinforces the hypothesis that Juan Macip was the most important painter in the Macip workshop during the 1530’s. It also fills a documental void in between the completion of the Silversmith’s Guild altarpiece (1534-1539 and the contract for the Fuente la Higuera altarpiece (1548. This study also verifies the popularity of the iconography of the seven sheddings of the Blood of Christ and processions of disciplinants.

En él se especifica que sea pintado por Juan, más conocido con posterioridad como Juan de Juanes. Se refuerza la hipótesis que permite concretar a Juan Macip como el pintor más importante del taller de los Macip durante la década de los 30, al tiempo que se llena un vacío documental entre la entrega del retablo del gremio de plateros (1534-1539 y la contratación del retablo de Fuente la Higuera (1548.

    2000-01-01

    Juan Gabriel's purported effeminacy and sexuality have made him a controversial subject in Mexico, but still loved by fans. Juan Gabriel, by trying to gain acceptance into Mexican society, has become part of a hybrid culture, between the feminine/masculine and homosexual/bisexual/heterosexual groups. This study focuses on interviews with 20 participants who discuss Juan Gabriel's popularity and sexuality. The findings of the study indicate that Juan Gabriel may be considered by his fans to be effeminate, and consequently homosexual. Even though homophobia is widespread in Mexico, Juan Gabriel's fans tend to ignore or exoticize his sexuality, thus affording his success. It is also possible that Juan Gabriel, consciously or not, uses his controversial sexuality as a way to generate popular interest.

    2013-08-01

    In 1554 Juan Valverde de Amusco, a Spanish anatomist, wrote the History of the composition of the human body, a complete anatomical treatise that took as its model the Vesalius school of thought (La fábrica of Vesalius). Considered one of the most complete anatomical treatises of the Renaissance and one of the most widely read books of the sixteenth century, it was translated into four languages in its day. The first chapter, devoted to bones, provides a meticulously detailed analysis of the bones of the facial structures and of the teeth, their supporting structures, vascularisation and innervation. Juan Valverde de Amusco even describes techniques for reducing mandibular luxations. Even with the imprecise observations typical of the time the treatise must be considered an exceptional document.

    Describes the one-man survey system which has been implemented at the San Juan surface mine in northwestern New Mexico. The Geodimeter System 4000, produced by Geotronics of Sweden, consists of a tripod-mounted electronic total station and a range rod-mounted remote positioning unit (RPU). A radio link between the tripod-mounted total station and the RPU enables one person to control the instrument and collect data. At San Juan the system has been used to survey overburden removal and mining. Only in cases where the pits become very long, and control cannot be set in the pit, is a two-person crew used. The system is useful for surveys of compliance projects and lends itself well to regrading work. 3 photos.

    Carlo Caso (1940 - 2007) Our friend and colleague Carlo Caso passed away on July 7th, after several months of courageous fight against cancer. Carlo spent most of his scientific career at CERN, taking an active part in the experimental programme of the laboratory. His long and fruitful involvement in particle physics started in the sixties, in the Genoa group led by G. Tomasini. He then made several experiments using the CERN liquid hydrogen bubble chambers -first the 2000HBC and later BEBC- to study various facets of the production and decay of meson and baryon resonances. He later made his own group and joined the NA27 Collaboration to exploit the EHS Spectrometer with a rapid cycling bubble chamber as vertex detector. Amongst their many achievements, they were the first to measure, with excellent precision, the lifetime of the charmed D mesons. At the start of the LEP era, Carlo and his group moved to the DELPHI experiment, participating in the construction and running of the HPC electromagnetic c...

    Full Text Available Currently, the environmental decision-making related to watershed preservation is oriented under the precepts of an historical environmental assessment. The objective of this research was to conduct a historical ecotoxicological assessment of the San Juan de Santiago de Cuba ecosystem. This was considered a systematic environmental monitoring which ran from 2010 to 2013, made q?uarterly. Physicochemical parameters such as electrical conductivity, total alkalinity, total hardness, pH, total solids, dissolved oxygen, biochemical oxygen demand and chemical oxygen demand were determined. All parameters of environmental risk prediction were performed using the GECOTOX program. The concentrations of Cu, Zn, Pb and Cd on three target organs (brain, gills and liver in the biomonitor adult Gambusia punctata (Poecilidae were analyzed. In this species, the effect of total protein and enzymatic activity of acetylcholinesterase as biomarkers were evaluated. In general, the parameters were outside the values set used by the Cuban quality standards. The GECOTOX program said that the waters of the San Juan ecosystem presented a high rate of risk. The highest concentrations of metals were determined in the gills, liver and brain, respectively. Biomarker values w? ere high, being higher for females. Finally, it was concluded that from one year to another all responses were ascending; thus, the San Juan ecosystem presented ecotoxicological effects in time.

    2015-01-01

    In 2010, in cooperation with the Mining and Minerals Division (MMD) of the State of New Mexico Energy, Minerals and Natural Resources Department, the U.S. Geological Survey (USGS) initiated a 4-year assessment of hydrologic conditions at the San Juan coal mine (SJCM), located about 14 miles west-northwest of the city of Farmington, San Juan County, New Mexico. The mine produces coal for power generation at the adjacent San Juan Generating Station (SJGS) and stores coal-combustion byproducts from the SJGS in mined-out surface-mining pits. The purpose of the hydrologic assessment is to identify groundwater flow paths away from SJCM coal-combustion-byproduct storage sites that might allow metals that may be leached from coal-combustion byproducts to eventually reach wells or streams after regional dewatering ceases and groundwater recovers to predevelopment levels. The hydrologic assessment, undertaken between 2010 and 2013, included compilation of existing data. The purpose of this report is to present data that were acquired and compiled by the USGS for the SJCM hydrologic assessment.

    The Monte Carlo method is widely used to numerically predict systems behaviour. However, its powerful incremental design assumes a strong premise which has severely limited application so far: the estimation process must combine linearly over dimensions. Here we show that this premise can be alleviated by projecting nonlinearities on a polynomial basis and increasing the configuration-space dimension. Considering phytoplankton growth in light-limited environments, radiative transfer in planetary atmospheres, electromagnetic scattering by particles and concentrated-solar-power-plant productions, we prove the real world usability of this advance on four test-cases that were so far regarded as impracticable by Monte Carlo approaches. We also illustrate an outstanding feature of our method when applied to sharp problems with interacting particles: handling rare events is now straightforward. Overall, our extension preserves the features that made the method popular: addressing nonlinearities does not compromise o...

    Charlie Samuya Veric

    2001-12-01

    Full Text Available The importance of Carlos Bulosan in Filipino and Filipino-American radical history and literature is indisputable. His eminence spans the pacific, and he is known, diversely, as a radical poet, fictionist, novelist, and labor organizer. Author of the canonical America Iis the Hearts, Bulosan is celebrated for chronicling the conditions in America in his time, such as racism and unemployment. In the history of criticism on Bulosan's life and work, however, there is an undeclared general consensus that views Bulosan and his work as coherent permanent texts of radicalism and anti-imperialism. Central to the existence of such a tradition of critical reception are the generations of critics who, in more ways than one, control the discourse on and of Carlos Bulosan. This essay inquires into the sphere of the critical reception that orders, for our time and for the time ahead, the reading and interpretation of Bulosan. What eye and seeing, the essay asks, determine the perception of Bulosan as the angel of radicalism? What is obscured in constructing Bulosan as an immutable figure of the political? What light does the reader conceive when the personal is brought into the open and situated against the political? the essay explores the answers to these questions in Bulosan's loving letters to various friends, strangers, and white American women. The presence of these interrogations, the essay believes, will secure ultimately the continuing importance of Carlos Bulosan to radical literature and history.

    2017-06-01

    LMC is a Markov Chain Monte Carlo engine in Python that implements adaptive Metropolis-Hastings and slice sampling, as well as the affine-invariant method of Goodman & Weare, in a flexible framework. It can be used for simple problems, but the main use case is problems where expensive likelihood evaluations are provided by less flexible third-party software, which benefit from parallelization across many nodes at the sampling level. The parallel/adaptive methods use communication through MPI, or alternatively by writing/reading files, and mostly follow the approaches pioneered by CosmoMC (ascl:1106.025).

    2015-12-01

    Full Text Available La obra proyectada y construida por Juan O’Gorman a lo largo de su vida traza un recorrido largo y sincopado entre formas de entender la arquitectura totalmente antagónicas. Su primera etapa de radical racionalismo desarrolla, según procedimientos estrictamente técnicos, un lenguaje revolucionario basado en la austeridad y la precisión. A pesar de ello muchas de sus obras destacan por la plasticidad de sus composiciones volumétricas, la riqueza espacial o, incluso, por la creación de atmósferas oníricas. Los primeros años de frenética actividad dan paso a un periodo de voluntario alejamiento de la práctica profesional de la arquitectura: ni una sola obra, ni un solo proyecto durante cerca de 15 años. Tan solo su actividad docente le mantiene en contacto con el mundo de la arquitectura. Cuando Juan O’Gorman vuelve a ejercer como arquitecto, lo hace construyendo algunos de los iconos del movimiento de integración plástica de México: la biblioteca central de la UNAM y su casa en San Jerónimo. A pesar de las enormes diferencias, o más bien oposiciones, entre unos momentos y otros, puede identificarse una invariante clara como señal de identidad personal: una velada voluntad de no ser arquitecto

    In July 1990 the company Iberduero, now Iberdrola, decided to carry out a development project using the Spanish technology SCAP in the Pasajes de San Juan power plant. This methodology, featured by the utilization of adaptive predictive control methodology, had been successfully applied in order to achieve the optimization of other industrial processes. The ultimate aim of this project was the replacement of the power station conventional control system, with a SCAP control system with a distributed structure able to optimize the electric energy generation process by optimizing power station operation, maximizing efficiency and working life, reducing maintenance costs, and increasing safety and availability. The project was divided into two stages to evaluate the quality of SCAP technology in the control and optimization of a power station. In the present report, the results obtained in the control of the most critical variables during the power station operation are gathered together. Beforehand, and in order to place these results in a suitable context, the project proceedings summarized in the following phases are considered: the SCAP technology; problems in a thermal power plant; and the Pasajes de San Juan power plant and its control system. The results are presented through comparative graphs that show the performance of the SCAP system as compared to the power station conventional control. 17 figs., 4 tabs., 11 refs.

    Full Text Available With over 8,100 traffic fatalities in 1997 and an accident rate per 100 million vehicle kilometres travelled, approximately five times that of United States, Argentinean road authorities are now beginning to focus attention on traffic safety and driver education. One of the main problems in the search of causes for car accidents in Argentina is the lack of a reliable and updated data base. The results and conclusions presented in this paper are based on a thorough analysis of car accidents in the Province of San Juan, Argentina. A seven-year data base of car accidents has been compiled from police reports, including the results of traffic counts at intersections and other collision locations. In addition, topographic and filmed reports of such places and their surroundings bring about parameters such as stop lines, visibility triangles, road size, traffic light performance, etc., which allow to carrying out of a traffic flow analysis for proposing measures aiming to minimize accidents. For San Juan province, in general, the main causes are: high absolute car speeds, speed differences between vehicles, lack of good lighting, poor driving habits, lack of traffic control devices such as signs, signals, and an absence of road markings.

    This study is one of a series of studies appraising the waterbearing properties of the Navajo Sandstone and associated formations in southern Utah.  The study area is about 4,600 square miles, extending from the Utah-Arizona State line northward to the San Juan-Grand County line and westward from the Utah-Colorado State line to the longitude of about 109°50'.Some of the water-yielding formations are grouped into aquifer systems. The C aquifer is comprised of the DeChelly Sandstone Member of the Cutler Formation.  The P aquifer is comprised of the Cedar Mesa Member of the Cutler Formation and the undifferentiated Cutler Formation. The N aquifer is comprised of the sedimentary section that includes the Wingate Sandstone, Kayenta Formation, Navajo Sandstone, Carmel Formation, and Entrada sandstone.  The M aquifer is comprised of the Bluff Sandstone Member and other sandstone units of the Morrison Formation.  The D aquifer is comprised of the Burro Canyon Formation and Dakota Sandstone.  Discharge from the ground-water reservoir to the San Juan River between gaging stations at Four Corners and Mexican Hat is about 66 cubic feet per second.The N aquifer is the main aquifer in the study area. Recharge by infiltration of precipitation is estimated to be 25,000 acre-feet per year.  A major ground-water divide exists under the broad area east of Monticello.  The thickness of the N aquifer, where the sedimentary section is fully preserved and saturated, generally is 750 to 1,250 feet.   Hydraulic conductivity values obtained from aquifer tests range from 0.02 to 0.34 foot per day.  The total volume of water in transient storage is about 11 million acre-feet. Well discharge somewhat exceeded 2,340 acre-feet during 1981.  Discharge to the San Juan River from the N aquifer is estimated to be 6.9 cubic feet per second.

    2014-10-01

    Full Text Available Resumen: Juan de Robles es uno de los más brillantes humanistas de nuestro Siglo de Oro, entre cuyas obras destaca El culto sevillano (1631. En este trabajo se analizan sus ideas educativas, centradas en la relación entre la ortografía y el aprendizaje de la escritura. Entre las ideas pedagógicas de Juan de Robles es muy relevante el rechazo vehemente de la ortografía fonética, entre otros motivos, porque no favorecía el aprendizaje de la lectura y de la escritura; en consecuencia, censura la creación de nuevas letras y de un nuevo orden para el alfabeto español. Los ortógrafos defensores de la ortografía fonética en el siglo XVII argumentaban que la nueva escritura permitiría a los niños aprender a leer y a escribir con más rapidez y facilidad; así como que la creación de nuevas letras y el establecimiento de un nuevo orden del alfabeto facilitarían su enseñanza. Frente a estas pretensiones, Juan de Robles defendió el alfabeto tradicional y la ortografía etimológica de origen latino porque eran los instrumentos adecuados para la alfabetización en nuestra lengua. También critica los colegios jesuitas y la Ratio Studiorum; las principales discrepancias entre la pedagogía de la Compañía de Jesús y las ideas educativas de Juan de Robles podrían concretarse en la primacía del español sobre el latín, y en el uso de cuentos y refranes populares para la educación en El culto sevillano. En conclusión, con la obra de Juan de Robles se incorpora definitivamente el argumento pedagógico que relaciona la ortografía y la gramática españolas con el aprendizaje de la lectura y de la escritura a la polémica sobre la ortografía española del Siglo de Oro, en defensa de la ortografía etimológica frente a las pretensiones de imponer una ortografía fonética en el primer tercio del siglo XVII.

Erected as a housing complex, the place consists of 768 flats distributed in buildings of three and seven floors each. A survey was carried out in 33% of the dwellings, enquiring about the number of Triatoma infestans found indoors, stage of the bug development - nymph or adult - and how these insects had entered their homes. Adult T.infestans were found on all floors; 163 people (64% had found them at least once, and 130 (51% several times. Dispersal flight seems to have been the main mechanism of infestation by adult bugs in this area, and a total of 51% of the surveyed inhabitants reported that the insects had flown into their flats.

  16. Central San Juan caldera cluster: regional volcanic framework

    Lipman, Peter W.

    2000-01-01

    Eruption of at least 8800 km3 of dacitic-rhyolitic magma as 9 major ash-slow sheets (individually 150-5000 km3) was accompanied by recurrent caldera subsidence between 28.3 and about 26.5 Ma in the central San Juan Mountains, Colorado. Voluminous andesitic-decitic lavas and breccias were erupted from central volcanoes prior to the ash-flow eruptions, and similar lava eruptions continued within and adjacent to the calderas during the period of explosive volcanism, making the central San Juan caldera cluster an exceptional site for study of caldera-related volcanic processes. Exposed calderas vary in size from 10 to 75 km in maximum diameter, the largest calderas being associated with the most voluminous eruptions. After collapse of the giant La Garita caldera during eruption if the Fish Canyon Tuff at 17.6 Ma, seven additional explosive eruptions and calderas formed inside the La Garita depression within about 1 m.y. Because of the nested geometry, maximum loci of recurrently overlapping collapse events are inferred to have subsided as much as 10-17 km, far deeper than the roof of the composite subvolcanic batholith defined by gravity data, which represents solidified caldera-related magma bodies. Erosional dissection to depths of as much as 1.5 km, although insufficient to reach the subvolcanic batholith, has exposed diverse features of intracaldera ash-flow tuff and interleaved caldera-collapse landslide deposits that accumulated to multikilometer thickness within concurrently subsiding caldera structures. The calderas display a variety of postcollapse resurgent uplift structures, and caldera-forming events produced complex fault geometries that localized late mineralization, including the epithermal base- and precious-metal veins of the well-known Creede mining district. Most of the central San Juan calderas have been deeply eroded, and their identification is dependent on detailed geologic mapping. In contrast, the primary volcanic morphology of the

    Science.gov (United States)

    Wick, Mark R

    2016-09-01

    Transmission electron microscopy (TEM) was introduced by Ruska and Knoll as a laboratory technique in 1933. Thereafter, several decades passed before the methods required for its optimal implementation were fully developed. Early uses of TEM were in Botany, rather than in Medicine; however, isolated publications did catalog the ultrastructural characteristics of several individual human tumor types. Finally, in 1968, Rosai and Rodriguez authored an important article, introducing the concept that TEM could be used for the differential diagnosis of histologically similar neoplasms. This publication heralded the steadily increasing application of TEM in anatomic pathology over the following decade, including continuing contributions by Dr. Juan Rosai. This brief review summarizes his influence on clinical electron microscopy, and lists some of the lesions for which that procedure is still a useful means of analysis.

The evolution of their inner temperatures and relative humidity with and without auxiliary thermal conditioning is analyzed. Conclusions assess the deficit level of the studied prototypes contrasted to international standards and the global valuation of the impact on the sectorial annual energy consumption caused by them.

    That deglaciation influences mid-ocean ridge volcanism is well established for Iceland, where depressurization associated with melting a ~2 km ice cap led to order of magnitude increases in volcanism during the last deglaciation. The case was also made that the more subtle ~100 m changes in sea level that accompany glacial cycles have identifiable implications for undersea mid-ocean ridge systems using both models and data from the Australian-Antarctic Ridge (Crowley et al., 2015). Sea level rising at ~1 cm/year during deglaciation leads to an expectation of ~10% decreases in melt production at ridges, given mantle upwelling rates of ˜3 cm/yr at intermediate spreading ridges and mantle density being ~3 times that of seawater. The implications of variations in melt production for bathymetry, however, involve numerous considerations, including whether melt signals are cancelled within the melt column, appreciably alter accretionary or fault processes, and have identifiable surface expressions. Further empirical assessment of bathymetry is thus useful for purposes of confirming patterns and constraining processes. Here we report on spectral analyses of bathymetry recently acquired from the Juan de Fuca ridge between 44°30'N and 45°15'N during the SeaVOICE expedition. Multibeam swath sonar data were acquired with an EM122 sonar insonfiying seafloor to crustal ages of ˜2 ma with 35 m spatial resolution. We examine (1.) the statistical significance of concentrations of bathymetric variability at the 100 ky, 41 ky, and 23 ky periods characteristic of late-Pleistocene sea level variability; (2.) whether sea level responses are primarily at 41 ky periods in crust accreted during the early Pleistocene, when global sea level variations were primarily at this period; and (3.) if sea level responses are superimposed on bathymetry variations or, instead, align with fault features. We also note that Juan de Fuca's proximity to the Cordilleran Ice Sheet implies that regional

De ahí que resulte tan relevante su encuentro con la poesía mística española, en la medida en que el místico es un exiliado de Dios (Citas y Comentarios, 1982, y con la poesía sefardí (Dibaxu, 1994, «como si la soledad extrema del exilio me empujara a buscar raíces en la lengua, las más profundas y exiliadas de la lengua».ABSTRACT: In the life of the Argentine poet Juan Gelman (1930, the traumatic experience of exile informs not only an important part of his production, the one that falls between 1975 and 1988, but also, and fundamentaly, it establishes the displacement to areas of significance in which language is also «the rejected», the «empty-passion», «the sign of an absence that does not finish writing itself», in his own words. From this, one discovers the importance of his encounter with Spanish mystical poetry, to the extent that the mystic is estranged from God (Citations and Comentaries, 1982 and with Sephardic poetry (Dibaxu, 1994, «as if the extreme solitude of exile compelled me to search for roots in language, the deepest and most estranged from language».

    Monte Carlo methods form an experimental branch of mathematics that employs simulations driven by random number generators. These methods are often used when others fail, since they are much less sensitive to the "curse of dimensionality", which plagues deterministic methods in problems with a large number of variables. Monte Carlo methods are used in many fields: mathematics, statistics, physics, chemistry, finance, computer science, and biology, for instance. This book is an introduction to Monte Carlo methods for anyone who would like to use these methods to study various kinds of mathemati

    In July 1985, the U.S. Geological Survey initiated a three-year study in San Juan County, New Mexico, to determine the concentrations of chemical constituents in the groundwater in the San Juan and Animas River valleys and to determine the direction and rate of groundwater flow and its relation to river stage. The study was conducted in cooperation with the San Juan County Commission and the New Mexico Oil Conservation Division. The data that was collected during the first 1-1/2 yr of the study is completed. The report includes well records for 51 wells and water levels from 23 wells, hydrographs from four observation wells and one river stage site, and available chemical analyses from 50 wells and 14 surface water sites. Water samples from six wells and one surface-water site were analyzed for purgeable organic chemicals; none were detected. (Lantz-PTT)

L. catesbeianus was first introduced to San Juan Province 11 years ago in Calingasta Department, where the habitat is pre-cordilleran. The new record is for Zonda Department, San Juan Province, in the Monte desert region. Here, L. catesbeianus uses artificial ponds for reproduction and tadpole development. These ponds receive water from an irrigation system that connects the whole agriculture land in the region. The tadpoles use the irrigation canals to move among ponds. We suggest that legislation should be established to prevent future invasions and to achieve sustainable management of the wild American bullfrog populations in San Juan. Prevention of future invasion and management of established populations of this species requires the cooperation of numerous stake holders.Se presenta un nuevo registro de Lithobates catesbeianus (rana toro americana en Argentina.

    Full Text Available Don Juan is a myth about a seducer, a man with many love adventures, a women’s heat conqueror, and many other predicates. Don Juan as a myth is well-known world wide over, appearing in about 50 writings such as novels, plays, operas. But a French writer Eric-Emannuel Schmitt proposes a new figure of Don Juan in his play La Nuit de Valognes (Night in Valognes: the seducer is judged by five victims and convicted to marry one of his victims in order to stop his adventures. Surprisingly, Don Juan accepts this verdict without conditions. This sudden change becomes the theme of the play: the demythification of Don Juan. A flash back scene shows the beginning of this change and the interpretations that might arise from here. One possible interpretation is proposed and discussed in this paper: Don Juan found the way to a purer love, which is the union with God, and decides to begin his journey. This play can thus be categorised as a sufi text.

    2016-08-29

    In this article we consider the approximation of expectations w.r.t. probability distributions associated to the solution of partial differential equations (PDEs); this scenario appears routinely in Bayesian inverse problems. In practice, one often has to solve the associated PDE numerically, using, for instance finite element methods which depend on the step-size level . hL. In addition, the expectation cannot be computed analytically and one often resorts to Monte Carlo methods. In the context of this problem, it is known that the introduction of the multilevel Monte Carlo (MLMC) method can reduce the amount of computational effort to estimate expectations, for a given level of error. This is achieved via a telescoping identity associated to a Monte Carlo approximation of a sequence of probability distributions with discretization levels . ∞>h0>h1⋯>hL. In many practical problems of interest, one cannot achieve an i.i.d. sampling of the associated sequence and a sequential Monte Carlo (SMC) version of the MLMC method is introduced to deal with this problem. It is shown that under appropriate assumptions, the attractive property of a reduction of the amount of computational effort to estimate expectations, for a given level of error, can be maintained within the SMC context. That is, relative to exact sampling and Monte Carlo for the distribution at the finest level . hL. The approach is numerically illustrated on a Bayesian inverse problem. © 2016 Elsevier B.V.

Por otro lado, sus textos, en diferentes niveles enunciativos, son parte de la conceptualización de esta misma experiencia. En este sentido, lo cinemático es un imaginario multiforme de la percepción del movimiento que culmina en el cine de vanguardia de los años veinte; mientras que lo cinematográfico se relaciona con el fenómeno del cine propiamente tal, sus posibilidades tecnológicas y los elementos que lo convierten en espectáculo. Estos polos tensionan la escritura de Emar en el nivel referencial, reflexivo, y estético-formal.

    The SPM is based on photographic plates taken at our observatory at El Leoncito, Argentina and will yield absolute proper motions and positions to magnitude B 19 for approximately 1 million stars south of declination -20 degrees. The SPM is a joint program between the Yale Southern Observatory and the Universidad Nacional de San Juan, Argentina. The SPM Catalog 2.0 provides positions, absolute proper motions, and photographic BV photometry for over 320,000 stars and galaxies. All objects contained in the SPM 1.0 Catalog (the South Galactic Pole region) are also included in this version. Note that SPM 1.0 has been replaced by SPM 1.1 which has slightly different astrometry (mostly proper motions) due to refinement of the magnitude equation correction in the SPM 2.0 Catalog. The Catalog covers an area of 3700 square degrees in an irregularly bounded band between declinations of -43 and -22 degrees, but excluding fields in the plane of the Milky Way. Stars cover the magnitude range 5 astrom/. Our web-site contains several useful plots showing the sky coverage, error distribution, a quick comparison with the Hipparcos proper motions, etc.

Estos personajes plantean fronteras móviles en su actuación pues la muerte les da un carácter ilimitado de acción perdiendo la secuencia histórica del presente-pasado-futuro. Asimismo se plantean algunas relaciones hipotéticas entre el autor y su obra señalando la polisemia resultante del uso de la metáfora. La estructura de la obra y la suspensión de las tramas hacen del lector un co-autor. A través del ensueño Rulfo inventa una manera de leer y escribir la muerte a través de su fantasmagoría.

Advanced Monte Carlo ‘moves’, required to optimize the speed of algorithms for a particular problem at hand, are outside the scope of this brief introduction. One particular modern example is the wavelet-accelerated MC sampling of polymer chains [406].

    Hurricane Juan provides an excellent opportunity to probe into the detailed wave spectral patterns and spectral parameters of a hurricane system, with enough wave spectral observations around Juan’s track in the deep ocean and shallow coastal water. In this study, Hurricane Juan and wave observation stations around Juan’s track are introduced. Variations of wave composition are discussed and analyzed based on time series of one-dimensional frequency spectra, as well as wave steepness around Juan’s track:before, dur-ing, and after Juan’s passing. Wave spectral involvement is studied based on the observed one-dimensional spectra and two-dimensional spectra during the hurricane. The standardization method of the observed wave spectra during Hurricane Juan is discussed, and the standardized spectra show relatively conservative behavior, in spite of the huge variation in wave spectral energy, spectral peak, and peak frequency during this hurricane. Spectral widths’ variation during Hurricane Juan are calculated and analyzed. A two-layer nesting WW3 model simulation is applied to simulate the one-dimensional and two-dimensional wave spectra, in order to examine WW3’s ability in simulating detailed wave structure during Hurricane Juan.

    We further study the validity of the Monte Carlo Hamiltonian method. The advantage of the method,in comparison with the standard Monte Carlo Lagrangian approach, is its capability to study the excited states. Weconsider two quantum mechanical models: a symmetric one V(x) = |x|/2; and an asymmetric one V(x) = ∞, forx < 0 and V(x) = x, for x ≥ 0. The results for the spectrum, wave functions and thermodynamical observables are inagreement with the analytical or Runge-Kutta calculations.

    The Proton Upset Monte Carlo Simulation (PROPSET) program calculates the frequency of on-orbit upsets in computer chips (for given orbits such as Low Earth Orbit, Lunar Orbit, and the like) from proton bombardment based on the results of heavy ion testing alone. The software simulates the bombardment of modern microelectronic components (computer chips) with high-energy (.200 MeV) protons. The nuclear interaction of the proton with the silicon of the chip is modeled and nuclear fragments from this interaction are tracked using Monte Carlo techniques to produce statistically accurate predictions.

    Full Text Available Abstract Background In contrast to DNA-mediated transposable elements (TEs, retrotransposons, particularly non-long terminal repeat retrotransposons (non-LTRs, are generally considered to have a much lower propensity towards horizontal transfer. Detailed studies on site-specific non-LTR families have demonstrated strict vertical transmission. More studies are needed with non-site-specific non-LTR families to determine whether strict vertical transmission is a phenomenon related to site specificity or a more general characteristic of all non-LTRs. Juan is a Jockey clade non-LTR retrotransposon first discovered in mosquitoes that is widely distributed in the mosquito family Culicidae. Being a non-site specific non-LTR, Juan offers an opportunity to further investigate the hypothesis that non-LTRs are genomic elements that are primarily vertically transmitted. Results Systematic analysis of the ~1.3 Gbp Aedes aegypti (Ae. aegypti genome sequence suggests that Juan-A is the only Juan-type non-LTR in Aedes aegypti. Juan-A is highly reiterated and comprises approximately 3% of the genome. Using minimum cutoffs of 90% length and 70% nucleotide (nt identity, 663 copies were found by BLAST using the published Juan-A sequence as the query. All 663 copies are at least 95% identical to Juan-A, while 378 of these copies are 99% identical to Juan-A, indicating that the Juan-A family has been transposing recently in evolutionary history. Using the 0.34 Kb 5' UTR as the query, over 2000 copies were identified that may contain internal promoters, leading to questions on the genomic impact of Juan-A. Juan sequences were obtained by PCR, library screening, and database searches for 18 mosquito species of six genera including Aedes, Ochlerotatus, Psorophora, Culex, Deinocerites, and Wyeomyia. Comparison of host and Juan phylogenies shows overall congruence with few exceptions. Conclusion Juan-A is a major genomic component in Ae. aegypti and it has been

    The Navajo Nation is America's largest native American tribe by population and acreage, and is blessed with large tracks of good coal deposits. BHP Billiton's New Mexico Coal Co. is the largest in the Navajo regeneration area. The holdings comprise the San Juan underground mine, the La Plata surface mine, now in reclamation, and the expanding Navajo surface mine. The article recounts the recent history of the mines. It stresses the emphasis on sensitivity to and helping to sustain tribal culture, and also on safety. San Juan's longwall system is unique to the nation. It started up as an automated system from the outset. Problems caused by hydrogen sulfide are being tackled. San Juan has a bleederless ventilation system to minimise the risk of spontaneous combustion of methane and the atmospheric conditions in the mine are heavily monitored, especially within the gob areas. 3 photos.

Investigó este culto colega en los años ochenta sobre la vida de algunos de nuestros prohombres, como Atanasio Girardot, José Hilario López y José Celestino Mutis, siendo este último libro comentado en mi columna semanal de otrora, la del diario barranquillense El Heraldo. Como todos los que llevan los genes Llinás, sus raíces estaban en Sabanalarga, de donde  era también el ilustre profesor y académico César Augusto Pantoja. Me honró Llinás con su amistad (al igual que su hijo Adolfo, el ortopedista. Edgardo Coronado –escritor e historiador de la segunda ciudad del Atlántico (por tamaño, pero la primera en antigüedad y en abolengos– dijo de él que “su experiencia de 30 años como profesor le dio paciencia, entendimiento y sabiduría, lo que le permitió escribir diez libros sobre temas de historia, ética, medicina y filosofía, que fueron su satisfacción y el camino para encontrarse y encontrar a los demás”. 

    Mi contacto personal con Llinás fue precisamente en la década de los ochenta, cuando en su condición de Coordinador del Programa de Ciencias Básicas de la recién fundada Universidad del Norte, me llamó en varias ocasiones para que dictara mis cursos de fisiología endocrina en este centro académico de excelencia, faro de ciencia y de cultura. Su fuerte eran –por supuesto– las humanidades. De vocablo educado y gentiles maneras, Juan Pablo sabía de medicina, de historia, de filosofía, de artes plásticas y de poesía. En un grupo de amigos de las letras y de las artes en Barranquilla, organizaba reuniones con amigos personales como el poeta Eduardo Carranza, o divagaba sobre el significado imaginario de esculturas enigmáticas del maestro Edgar Negret.

    Objective The metabolic syndrome is associated with a high risk of diabetes and cardiovascular disease, and Hispanics in the United States have higher rates than do other ethnic groups. We assessed the prevalence of the metabolic syndrome and its individual components in Puerto Rican adults. Methods We conducted a cross-sectional study that used a probability cluster design to select a sample of households of the San Juan metropolitan area from 2005 through 2007. A total of 859 persons aged 21–79 years completed a face-to-face interview, blood pressure and waist circumference measurements, and blood sampling. Our primary outcome measure was metabolic syndrome as defined by the updated NCEP-ATP criteria. Results Prevalence of the metabolic syndrome was 43.3%; 45.3% for men and 42.2% for women (P>.05). Prevalence significantly rose with age, from 12.8% among participants aged 21–29 years to 58.2% for participants aged 70–79 years (P<.001). Corresponding increases in the prevalence of the metabolic syndrome in both men and women were also observed; the prevalence peaked in men aged 50–59 years (62.6%) and in women aged 70–79 years (65.2%). Elevated glucose (49.8%) and abdominal obesity (49.0%) were the most common components of the metabolic syndrome, followed by elevated blood pressure (46.1%), reduced high-density lipoprotein cholesterol (46.0%), and elevated triglycerides (31.3%). Substantial variations were found between men and women in the prevalence of individual components. Conclusions Puerto Ricans have a high prevalence of the metabolic syndrome. This health disparity has implications for diabetes and cardiovascular prevention programs. PMID:19157247

  10. El anti-don Juan de María de Zayas

    Directory of Open Access Journals (Sweden)

    Trambaioli, Marcella

    2014-12-01

    Full Text Available All critics agree on considering that María de Zayas writes inspired by the anger that she feels for the women condition. Both in her prose and in the only play we know, La traición en la amistad, Zayas censures with irony and wit the don-Juan type who deceives women leaving them without honour. She does it elaborating an intertextual relationship with El burlador de Sevilla. Specifically, in the play she uses three characters: Liseo, who deceives three women, Fenisa, who is a don-Juan female even more exaggerated than Liseo, and don Juan, the less donjuanesco of all. As a matter of fact, Zayas creates an anti-don Juan similar to the one that Ventura de la Vega will realize in the XIX century with his play El hombre de mundo, a parody of Zorrilla’s Don Juan Tenorio; nevertheless it has a clear ethical purpose: to warn women of his age in order to avoid men’s abuses.Los críticos concuerdan en que María de Zayas escribe inspirada por la cólera que le provoca la condición femenina coetánea. Tanto en sus novelas como en la única comedia conservada, La traición en la amistad, Zayas censura con sutil ironía al tipo donjuanesco que se burla de las mujeres dejándolas sin honor, y lo hace entablando un complejo e ingenioso diálogo intertextual con El burlador de Sevilla. De forma especial, en la pieza lo hace a través de tres figuras: Liseo, que engaña a tres mujeres, Fenisa, un don Juan mujer aún más hiperbólico que Liseo, y don Juan, el menos donjuanesco de todos. En definitiva, crea un anti-don Juan parecido al que Ventura de la Vega realizará en el siglo XIX con El hombre de mundo, parodia del Tenorio de Zorrilla, pero con una clara intencionalidad ética: la de aleccionar a las mujeres de su época para que aprendan a esquivar a los hombres que abusan de ellas.

    The article describes the authors and works which were quoted by the Franciscan Juan Gil de Zamora in his Historia naturalis, a scientific encyclopaedia written between c. 1275 and before 1296, probably in the Franciscan monastery of Zamora (Kingdom of Castille). Juan Gil made wide use of the Avicenna's Canon, Gilbertus de Aquila (Anglicus)'s Compendium medicine, and Salernitan medical literature. His work contributed to the diffusion of these medical authors and works throughout the Christian intellectual milieu of late medieval Castille. This diffusion was not without problems.

    The aim of this article is to present and analyse four dietary prescriptions from the 16th century prepared for Juan Rena, a cleric of Venetian origin, and his servant Juan de Alarcón, which are kept at the Archivo General de Navarra. These documents demonstrate the interest of the patients and physicians in dietetics, understood as a group of health and hygienic measures based on the Galenic res naturales and res non naturales. These four prescriptions are closely related to the ad personam or consilia health regimens, which represent a genre of medical literature whose significance in Renaissance Spain has received little attention. The cases studied reveal the high esteem in which the elites held the possession of therapeutic resources adapted to their individual needs, which were compiled and copied for personal use.

    Blunt, N S; Spencer, J S; Foulkes, W M C

    2013-01-01

    This paper describes a quantum Monte Carlo method capable of sampling the full density matrix of a many-particle system, thus granting access to arbitrary reduced density matrices and allowing expectation values of complicated non-local operators to be evaluated easily. The direct sampling of the density matrix also raises the possibility of calculating previously inaccessible entanglement measures. The algorithm closely resembles the recently introduced full configuration interaction quantum Monte Carlo method, but works all the way from infinite to zero temperature. We explain the theory underlying the method, describe the algorithm, and introduce an importance-sampling procedure to improve the stochastic efficiency. To demonstrate the potential of our approach, the energy and staggered magnetization of the isotropic antiferromagnetic Heisenberg model on small lattices and the concurrence of one-dimensional spin rings are compared to exact or well-established results. Finally, the nature of the sign problem...

    Schulze, Tim P.

    2008-02-01

    This paper concerns kinetic Monte Carlo (KMC) algorithms that have a single-event execution time independent of the system size. Two methods are presented—one that combines the use of inverted-list data structures with rejection Monte Carlo and a second that combines inverted lists with the Marsaglia-Norman-Cannon algorithm. The resulting algorithms apply to models with rates that are determined by the local environment but are otherwise arbitrary, time-dependent and spatially heterogeneous. While especially useful for crystal growth simulation, the algorithms are presented from the point of view that KMC is the numerical task of simulating a single realization of a Markov process, allowing application to a broad range of areas where heterogeneous random walks are the dominate simulation cost.

    This work generalizes a multilevel forward Euler Monte Carlo method introduced in Michael B. Giles. (Michael Giles. Oper. Res. 56(3):607–617, 2008.) for the approximation of expected values depending on the solution to an Itô stochastic differential equation. The work (Michael Giles. Oper. Res. 56(3):607– 617, 2008.) proposed and analyzed a forward Euler multilevelMonte Carlo method based on a hierarchy of uniform time discretizations and control variates to reduce the computational effort required by a standard, single level, Forward Euler Monte Carlo method. This work introduces an adaptive hierarchy of non uniform time discretizations, generated by an adaptive algorithmintroduced in (AnnaDzougoutov et al. Raùl Tempone. Adaptive Monte Carlo algorithms for stopped diffusion. In Multiscale methods in science and engineering, volume 44 of Lect. Notes Comput. Sci. Eng., pages 59–88. Springer, Berlin, 2005; Kyoung-Sook Moon et al. Stoch. Anal. Appl. 23(3):511–558, 2005; Kyoung-Sook Moon et al. An adaptive algorithm for ordinary, stochastic and partial differential equations. In Recent advances in adaptive computation, volume 383 of Contemp. Math., pages 325–343. Amer. Math. Soc., Providence, RI, 2005.). This form of the adaptive algorithm generates stochastic, path dependent, time steps and is based on a posteriori error expansions first developed in (Anders Szepessy et al. Comm. Pure Appl. Math. 54(10):1169– 1214, 2001). Our numerical results for a stopped diffusion problem, exhibit savings in the computational cost to achieve an accuracy of ϑ(TOL),from(TOL−3), from using a single level version of the adaptive algorithm to ϑ(((TOL−1)log(TOL))2).

    Acute toxicity tests were conducted with larval Colorado squawfish (Ptychocheilus lucius) and razorback sucker (Xyrauchen texanus) in a constituted water quality simulating the San Juan River near Shiprock, New Mexico. Tests were conducted with arsenate, copper, selenate, selenite, zinc, and five mixtures of seven to nine inorganics simulating environmental mixtures reported for sites along the San Juan River (Ojo Amarillo Canyon, Gallegos Canyon, Hogback East Drain, Mancos River, and McElmo Creek). Razorback suckers were significantly more sensitive to arsenate, selenate, selenite, Hogback East Drain mixture, and Ojo Amarillo Canyon mixture than were Colorado squawfish. The Gallegos Canyon mixture had greater than additive, i.e., synergistic, toxicity to both species, the Ojo Amarillo Canyon mixture had less than additive, i.e., antagonistic, toxicity to both species, and the Mancos River and McElmo Creek mixtures had additive toxicity to both species. The Hogback East Drain mixture had additive toxicity to Colorado squawfish, but synergistic toxicity to razorback suckers. The major toxic component in the five mixtures was copper. Comparison of 96-hour LC50 values with a limited number of environmental water concentrations from the San Juan River revealed high hazard ratios for copper and all five environmental mixtures. The high hazard ratios suggest inorganic contaminants could adversely affect larval Colorado squawfish and razorback suckers in the San Juan River at sites receiving elevated inorganics.

    Nova Scotia Power Inc. (NSPI) has responded to several recommendations made by an independent consultant regarding its emergency response to Hurricane Juan which hit the Halifax Regional Municipality on September 28, 2003. NSPI is in agreement with most of the recommendations and is enhancing its preparedness for use in disaster scenarios similar to Hurricane Juan. Several recommendations have already been implemented by the power company including, improvements to call centre technology and processes, and better coordination with the electricity market operator and municipal responders. Lessons learned from Hurricane Juan were applied during a snow storm in February 2004, particularly in terms of communications. NSPI strongly disagrees with the consultant's recommendation to bring in hundreds of line crews from outside the region in advance of a major storm. NSPI argues that doing so, would have tripled or quadrupled Hurricane Juan costs to $40 or $50 million with little or no improvement on restoration times. Nova Scotia Power Inc. is a wholly-owned subsidiary of Emera (EMA-TSX). The utility provides more than 97 per cent of electric generation, transmission, and distribution to more than 460,000 customers across Nova Scotia. NSPI is committed to supporting Nova Scotian communities by providing safe, reliable power.

    The behavior of the one-dimensional random-force-driven Burgers equation is investigated in the path integral formalism on a discrete space-time lattice. We show that by means of Monte Carlo methods one may evaluate observables, such as structure functions, as ensemble averages over different field realizations. The regularization of shock solutions to the zero-viscosity limit (Hopf-equation) eventually leads to constraints on lattice parameters required for the stability of the simulations. Insight into the formation of localized structures (shocks) and their dynamics is obtained. (orig.)

    2013-01-01

    Modern cancer treatment relies on Monte Carlo simulations to help radiotherapists and clinical physicists better understand and compute radiation dose from imaging devices as well as exploit four-dimensional imaging data. With Monte Carlo-based treatment planning tools now available from commercial vendors, a complete transition to Monte Carlo-based dose calculation methods in radiotherapy could likely take place in the next decade. Monte Carlo Techniques in Radiation Therapy explores the use of Monte Carlo methods for modeling various features of internal and external radiation sources, including light ion beams. The book-the first of its kind-addresses applications of the Monte Carlo particle transport simulation technique in radiation therapy, mainly focusing on external beam radiotherapy and brachytherapy. It presents the mathematical and technical aspects of the methods in particle transport simulations. The book also discusses the modeling of medical linacs and other irradiation devices; issues specific...

    We present a new hybrid Monte Carlo method for 1-D equilibrium diffusion problems in which the radiation field coexists with matter in local thermodynamic equilibrium. This method, the Equilibrium Discrete Diffusion Monte Carlo (EqDDMC) method, combines Monte Carlo particles with spatially discrete diffusion solutions. We verify the EqDDMC method with computational results from three slab problems. The EqDDMC method represents an incremental step toward applying this hybrid methodology to non-equilibrium diffusion, where it could be simultaneously coupled to Monte Carlo transport.

A fin de aclarar el tema se realizó el relevamiento de un sector del Valle de Iglesia. En este artículo se presentan los resultados de ese estudio, junto con una revisión y discusión de los antecedentes y de algunas ideas vinculadas con el tema. Fundamentalmente, se verifica la presencia del Qhapaq Ñan en la parte baja del sector analizado, se refuta la propuesta de que el trazado longitudinal principal se habría extendido por la parte alta del sector precordillerano y se sostiene que el tramo relevado fue recorrido por Debenedetti a principios del siglo XX, aunque sin advertir que se trataba del camino incaico.   Palabras clave: Inca; Camino del Inca; Dominación incaica; Collasuyo; San Juan   Abstract The Inka road system in the longitudinal valleys of San Juan province, in the southeastern end of Tawantinsuyu, has been subject of several considerations during the last century.

The author outlines how she hurriedly wrote a text about Don Juan which, however, was rejected by the editor. Essential parts of it are presented in German translation. The manuscript is discussed in the context of Klein's published work as well as of the relevant contemporary literature. In Klein's view, Don Juan's genitality is determined by oral impulses and fears. By his manic acting out he attempts to ward off a depressive break-down. The paper ends with some reflections about why Klein--ontrary to her intention--failed to revise her manuscript for later publication.

    Full Text Available In this paper is presented a slate with a Roman inscription found in archaeological survey work conducted in September 2014 in Cortinal de San Juan (Salvatierra de Tormes. This site has been, since its discovery and cataloging, a place of reference for the late Roman and Visigothic settlement Southeast Salamanca. Currently, this archaeological site is partially flooded by the Santa Teresa swamp. The main feature of this Roman inscription is that the slate support isn’t usual in the chronology proposed for such inscription. Despite the fact that other archaeological materials of Cortinal de San Juan are associated with late Roman or Visigothic chronocultural context, the type of capital letter, the large size of the letter, and the parallels established with other finds of similar chronology suggest this inscription could be part of a Roman anthroponym as the most successful interpretive hypothesis.

    Lipman, Peter W.

    2012-01-01

    The San Juan Mountains in southwestern Colorado have long been known as a site of exceptionally voluminous mid-Tertiary volcanism, including at least 22 major ignimbrite sheets (each 150-5,000 km3) and associated caldera structures active at 33-23 Ma. Recent volcanologic and petrologic studies in the San Juan region have focused mainly on several ignimbrite-caldera systems: the southeastern area (Platoro complex), western calderas (Uncompahgre-Silverton-Lake City), and the central cluster (La Garita-Creede calderas). Far less studied has been the northeastern San Juan region, which occupies a transition between earlier volcanism in central Colorado and large-volume younger ignimbrite-caldera foci farther south and west. The present map is based on new field coverage of volcanic rocks in seventeen 7.5' quadrangles in northeastern parts of the volcanic field, high-resolution age determinations for 120 new sites, and petrologic studies involving several hundred new chemical analyses. This mapping and the accompanying lab results (1) document volcanic evolution of the previously unrecognized North Pass caldera and the morphologically beautifully preserved but enigmatic Cochetopa basin, including unique features not previously described from ignimbrite calderas elsewhere; (2) provide evidence for a more rapid recurrence of large ignimbrite eruptions than previously known elsewhere; (3) quantify the regional time-space-volume progression from the earlier Sawatch magmatic trend southward into the San Juan region; and (4) permit more rigorous comparison between the broad mid-Tertiary magmatic belt in the western U.S. Cordillera and the type continental-margin arc volcanism in the central Andes.

  8. The paradigm of paraglacial megafans of the San Juan river basin, Central Andes, Argentina

    Suvires, Graciela M.

    2014-11-01

    The spatial distribution and several morphometric characteristics of the Quaternary alluvial fans of the San Juan River, in the province of San Juan, at the Central and Western part of Argentina, have been studied to classify them as paraglacial megafans, as well to ratify its depositional environmental conditions. The high sedimentary load exported by San Juan river from the Central Andes to the foreland depressions is estimated about 3,682,200 hm3. The large alluvial fans of Ullum-Zonda and Tulum valleys were deposited into deep tectonic depressions, during the Upper Pleistocene deglaciation stages. The outcome of collecting remotely sensed data, map and DEM data, geophysical data and much fieldwork gave access to morphometric, morphographic and morphogenetic data of these alluvial fans. The main drainage network was mapped on processed images using QGis (vers.2.0.1). Several fan morphometric parameters were measured, such as the size, the shape, the thickness, the surface areas and the sedimentary volume of exported load. The analyzed fans were accumulated in deep tectonic depressions, where the alluvium fill reaches 700 to 1200 m thick. Such fans do not reach the large size that other world megafans have, and this is due to tectonic obstacles, although the sedimentary fill average volume surpasses 514,000 hm3. The author proposes to consider Ullum-Zonda and Tulum alluvial fans as paraglacial megafans. According to the stratigraphic relationships of the tropical South American Rivers, the author considers that the San Juan paraglacial megafans would have occurred in the period before 24 ka BP , possibly corresponding to Middle Pleniglacial (ca 65-24ka BP). They record colder and more humid conditions compared with the present arid and dry conditions.

    Fruitland coals are best developed in the north-central part of the San Juan basin. Coal distribution is controlled by shoreline and fluvial depositional settings. Hydraulic gradient, pressure regime, and hydrochemistry reflect regional permeability contrasts. The most productive (>1 MMcf/D) coalbed wells occur along a structural hinge line in association with a regional permeability barrier (no-flow boundary) at the basin center.

  4. Juan de Fuca slab geometry and its relation to Wadati-Benioff zone seismicity

    2012-01-01

    A new model of the subducted Juan de Fuca plate beneath western North America allows first-order correlations between the occurrence of Wadati-Benioff zone earthquakes and slab geometry, temperature, and hydration state. The geo-referenced 3D model, constructed from weighted control points, integrates depth information from earthquake locations and regional seismic velocity studies. We use the model to separate earthquakes that occur in the Cascadia forearc from those that occur within the underlying Juan de Fuca plate and thereby reveal previously obscured details regarding the spatial distribution of earthquakes. Seismicity within the slab is most prevalent where the slab is warped beneath northwestern California and western Washington suggesting that slab flexure, in addition to expected metamorphic dehydration processes, promotes earthquake occurrence within the subducted oceanic plate. Earthquake patterns beneath western Vancouver Island are consistent with slab dehydration processes. Conversely, the lack of slab earthquakes beneath western Oregon is consistent with an anhydrous slab. Double-differenced relocated seismicity resolves a double seismic zone within the slab beneath northwestern California that strongly constrains the location of the plate interface and delineates a cluster of seismicity 10 km above the surface that includes the 1992 M7.1 Mendocino earthquake. We infer that this earthquake ruptured a surface within the Cascadia accretionary margin above the Juan de Fuca plate. We further speculate that this earthquake is associated with a detached fragment of former Farallon plate. Other subsurface tectonic elements within the forearc may have the potential to generate similar damaging earthquakes.

    The San Juan Mountains are the largest erosional remnant of a composite volcanic field that covered much of the southern Rocky Mountains in middle Tertiary time. The San Juan field consists mainly of intermediate-composition lavas and breccias, erupted about 35-30 Ma from scattered central volcanoes (Conejos Formation) and overlain by voluminous ash-flow sheets erupted from caldera sources. In the central San Juan Mountains, eruption of at least 8,800 km3 of dacitic-rhyolitic magma as nine major ash flow sheets (individually 150-5,000 km3) was accompanied by recurrent caldera subsidence between 28.3 Ma and about 26.5 Ma. Voluminous andesitic-dacitic lavas and breccias erupted from central volcanoes prior to the ash-flow eruptions, and similar lava eruptions continued within and adjacent to the calderas during the period of more silicic explosive volcanism. Exposed calderas vary in size from 10 to 75 km in maximum dimension; the largest calderas are associated with the most voluminous eruptions.

    The concentration, potential mobility, cation exchange capacity and toxicity of eight sediment-bound metals in Golfe-Juan Bay, France were examined. Results revealed significant spatial gradient of metal contamination along Golfe-Juan coast. The distribution and concentration of the metals appear to be influenced by the geochemical properties of the sediment, proximity to anthropogenic sources and general water circulation in the bay. The portion of trace metals found in the exchangeable, carbonate, oxidizable and reducible fractions of the sediment constitute 31%-58% of the total sediment-bound trace metal content, suggesting significant potential for remobilization of metals into the water column. Pb and Ni content of the sediment exceed the limits of the French marine sediment quality. Whole sediment extracts showed acute toxicity to marine rotifers. This study concludes that monitoring and management of sediment-bound trace metals in Golfe-Juan Bay are important so as not to underestimate their availability and risk to the marine ecosystems.

    Tectonic plates are underlain by a low-viscosity mantle layer, the asthenosphere. Asthenospheric flow may be induced by the overriding plate or by deeper mantle convection. Shear strain due to this flow can be inferred using the directional dependence of seismic wave speeds--seismic anisotropy. However, isolation of asthenospheric signals is challenging; most seismometers are located on continents, whose complex structure influences the seismic waves en route to the surface. The Cascadia Initiative, an offshore seismometer deployment in the US Pacific Northwest, offers the opportunity to analyse seismic data recorded on simpler oceanic lithosphere. Here we use measurements of seismic anisotropy across the Juan de Fuca and Gorda plates to reconstruct patterns of asthenospheric mantle shear flow from the Juan de Fuca mid-ocean ridge to the Cascadia subduction zone trench. We find that the direction of fastest seismic wave motion rotates with increasing distance from the mid-ocean ridge to become aligned with the direction of motion of the Juan de Fuca Plate, implying that this plate influences mantle flow. In contrast, asthenospheric mantle flow beneath the Gorda Plate does not align with Gorda Plate motion and instead aligns with the neighbouring Pacific Plate motion. These results show that asthenospheric flow beneath the small, slow-moving Gorda Plate is controlled largely by advection due to the much larger, faster-moving Pacific Plate.

    Gries, R.R.

    1985-05-01

    During the Tertiary, the western part of the northern Sange de Cristo Range dropped 16,000 ft (4877 m) to become what is now known as the San Luis basin. The foreland basin formerly adjacent to and west of the range remained intact but was subsequently concealed by 10,000 ft (3048 m) of volcanic deposits. The existence of this concealed basin, a northeastern arm of the San Juan basin, was first suggested by Vincent Kelly who named it the San Juan sag. Oil, which was generated in the underlying Mancos Shale, migrated upward into vesicles and fractures in volcanic rocks. In at least two places, oil is currently seeping onto the volcanic surface or into overlying soil. These oil occurrences encouraged geologic and geophysical exploration and have led to confirmation by drilling that the basin exists. Porous reservoirs in both tertiary sedimentary rocks and volcanic rocks overlie a 2000 ft (610 m) Cretaceous Mancos Shale source rock. Within the Mancos Shale are fractured reservoirs, volcanic sills that have reservoir potential where fractured or porous, and stray sandstones. The Dakota Formation underlies the Mancos Shale and is about 200 ft (61 m) thick in this area. In addition, the Jurassic section has potential for source rocks in the Todilto Formation and reservoir rocks in the Entrada and Junction Creek Sandstones. The San Juan sag, a newly discovered basin of 2600 miS (6734 kmS) is a frontier for Colorado oil and gas exploration.

    These are slides from a presentation for Parallel Summer School at Los Alamos National Laboratory. Solving discretized partial differential equations (PDEs) of interest can require a large number of computations. We can identify concurrency to allow parallel solution of discrete PDEs. Simulated particles histories can be used to solve the Boltzmann transport equation. Particle histories are independent in neutral particle transport, making them amenable to parallel computation. Physical parameters and method type determine the data dependencies of particle histories. Data requirements shape parallel algorithms for Monte Carlo. Then, Parallel Computational Physics and Parallel Monte Carlo are discussed and, finally, the results are given. The mesh passing method greatly simplifies the IMC implementation and allows simple load-balancing. Using MPI windows and passive, one-sided RMA further simplifies the implementation by removing target synchronization. The author is very interested in implementations of PGAS that may allow further optimization for one-sided, read-only memory access (e.g. Open SHMEM). The MPICH_RMA_OVER_DMAPP option and library is required to make one-sided messaging scale on Trinitite - Moonlight scales poorly. Interconnect specific libraries or functions are likely necessary to ensure performance. BRANSON has been used to directly compare the current standard method to a proposed method on idealized problems. The mesh passing algorithm performs well on problems that are designed to show the scalability of the particle passing method. BRANSON can now run load-imbalanced, dynamic problems. Potential avenues of improvement in the mesh passing algorithm will be implemented and explored. A suite of test problems that stress DD methods will elucidate a possible path forward for production codes.

    Full Text Available Carlos Restrepo fue el primer profesor de Patología y un miembro ilustre del grupo de pioneros que fundaron la Facultad de Medicina de la Universidad del Valle. Estos pioneros convergieron en Cali en la década de 1950, en posesión de un espíritu renovador y creativo que emprendió con mucho éxito la labor de cambiar la cultura académica del Valle del Cauca. Ellos encontraron una sociedad apacible, que disfrutaba de la generosidad de su entorno, sin deseos de romper las tradiciones centenarias de estilo de vida sencillo y satisfecho. Cuando los hijos tenían el deseo y la capacidad de seguir estudios universitarios, especialmente en el área de la medicina, la familia los enviaba a climas menos cálidos, que supuestamente favorecían la función cerebral y la acumulación de conocimientos. Los pioneros de la educación médica en el Valle del Cauca, en buena parte reclutados en universidades nacionales y extranjeras, sabían muy bien que el ambiente vallecaucano no impide una formación universitaria de primera clase. Carlos Restrepo era prototipo del espíritu de cambio y formación intelectual de las nuevas generaciones. Lo manifestaba de múltiples maneras, en buena parte con su genio alegre, extrovertido, optimista, de risa fácil y contagiosa. Pero esta fase amable de su personalidad no ocultaba su tarea formativa; exigía de sus discípulos dedicación y trabajo duro, con fidelidad expresados en memorables caricaturas que exageraban su genio ocasionalmente explosivo. El grupo de pioneros se enfocó con un espíritu de total entrega (tiempo completo y dedicación exclusiva y organizó la nueva Facultad en bien definidos y estructurados departamentos: Anatomía, Bioquímica, Fisiología, Farmacología, Patología, Medicina Interna, Cirugía, Obstetricia y Ginecología, Psiquiatría y Medicina Preventiva. Los departamentos integraron sus funciones primordiales en la enseñanza, la investigación y el servicio a la comunidad. El centro

  20. The MC21 Monte Carlo Transport Code

    Sutton TM, Donovan TJ, Trumbull TH, Dobreff PS, Caro E, Griesheimer DP, Tyburski LJ, Carpenter DC, Joo H

    2007-01-09

    MC21 is a new Monte Carlo neutron and photon transport code currently under joint development at the Knolls Atomic Power Laboratory and the Bettis Atomic Power Laboratory. MC21 is the Monte Carlo transport kernel of the broader Common Monte Carlo Design Tool (CMCDT), which is also currently under development. The vision for CMCDT is to provide an automated, computer-aided modeling and post-processing environment integrated with a Monte Carlo solver that is optimized for reactor analysis. CMCDT represents a strategy to push the Monte Carlo method beyond its traditional role as a benchmarking tool or ''tool of last resort'' and into a dominant design role. This paper describes various aspects of the code, including the neutron physics and nuclear data treatments, the geometry representation, and the tally and depletion capabilities.

  1. The Literary Criticism and Memoirs of Juan Ramón Jiménez

    Directory of Open Access Journals (Sweden)

    Allen W. Phillips

    1983-01-01

    Full Text Available Equally as demanding of others as he was of himself, Juan Ramón Jiménez conceived of literary criticism as a serious and exacting task. The critic and the poet, standing side by side, are devoted to complementary activities of mutual enrichment. However fragmentary and partial the critical opinions of Juan Ramón may be (also outspoken and polemical in nature, they are invaluable as a personal historical and aesthetic guide to about fifty or sixty years of Hispanic literary development (1900-1960. Not to take them into account is to fail to recognize a highly important aspect of his total artistic personality. These varied critical texts are a product of a first rate intelligence and the sensibility of a writer of consummate discrimination who was endowed not only with an excellent memory but also a very special talent for appreciating the authentic. Juan Ramón as a critic is quick to praise (San Juan, Bécquer, Dario, Unamuno and Machado and at the same time strong in his censure of certain contemporaries. Several recently collected volumes of miscellaneous critical materials have resolved the bibliographical muddle for the initial study of this fundamental aspect of the poet, but still particularly important are the expressionistic portraits of Españoles de tres mundos , longer tributes to Valle, Ortega and Villaespesa as well as the extensive lectures delivered in his latter years. Examination of these pages gives us an historical and creative overview of the period in which he lived and worked in addition to original considerations about the evolution of Hispanic poetry. Of course, one of the constant focal points of his literary criticism was the modernist epoch of his early days, a movement or attitude which he considered to be a modern twentieth century renaissance. Together with detailed study of these two areas of historical and aesthetic nature, in the ensuing pages some conclusions are pointed out as to the essence of poetry

    Multibeam data collected using a Kongsberg EM122 sonar system on the NOAA ship R/V Marcus G. Langseth led by chief scientist Douglas Toomey (University of Oregon) in 2009 and with a Simrad EM302 sonar system on two NOAA ship Okeanos Explorer cruises led by chief scientists James Gardner (University of New Hampshire) and Catalina Martinez (University of Rhode Island) in 2009 show the morphology of the Juan de Fuca and Gorda Ridges, as well as the Blanco and Mendocino Fracture Zones. These ridges and fracture zones comprise the divergent plate boundary of the eastern edge of the Pacific Plate and the western edges of the Juan de Fuca and Gorda Plates. Both plates are being subducted beneath the western edge of the North American Plate. CARIS HIPS 8.1 software was used to process the multibeam data and create bathymetric images. The ridge axes, located off the coast of Washington and Oregon (USA) adjacent to the Cascadia Basin, indicate obvious signs of spreading, due to the series of faults and rocky ridges aligned parallel to the plate boundaries. Fault and ridge orientations are used to compare the direction of seafloor spreading, and indicate that both the Juan de Fuca Plate and Gorda Plate are spreading in a southeastern direction. Younger ridges from the Gorda Ridge system mapped in the study run parallel to the boundary, however older ridges do not show the same orientation, indicating a change in spreading direction. The presence of hydrothermal vents along the Juan de Fuca Ridge is also evidence of the active boundary, as the vent chimneys are composed of minerals and metals precipitated from the hot water heated by magma from beneath the spreading seafloor. In this study, the data are used to compare and contrast earthquake seismicity and ridge morphologies at a depth range of approximately 762 to 2134 meters. The diverging Pacific, Juan de Fuca, and Gorda Plates along with the San Andreas Fault have potential to increase seismic and volcanic activity around

    1990-01-01

    Significant progress has been made recently in the application of Monte Carlo methods to the study of light nuclei. We review new Green's function Monte Carlo results for the alpha particle, Variational Monte Carlo studies of {sup 16}O, and methods for low-energy scattering and transitions. Through these calculations, a coherent picture of the structure and electromagnetic properties of light nuclei has arisen. In particular, we examine the effect of the three-nucleon interaction and the importance of exchange currents in a variety of experimentally measured properties, including form factors and capture cross sections. 29 refs., 7 figs.

    2012-01-01

    A new Monte Carlo method termed Comb-like frame Monte Carlo is developed to simulate the soot dynamics. Detailed stochastic error analysis is provided. Comb-like frame Monte Carlo is coupled with the gas phase solver Chemkin II to simulate soot formation in a 1-D premixed burner stabilized flame. The simulated soot number density, volume fraction, and particle size distribution all agree well with the measurement available in literature. The origin of the bimodal distribution of particle size distribution is revealed with quantitative proof.

    CERN Document Server

    Wagner, Lucas K

    2010-01-01

    We present an efficient method to find minimum energy structures using energy estimates from accurate quantum Monte Carlo calculations. This method involves a stochastic process formed from the stochastic energy estimates from Monte Carlo that can be averaged to find precise structural minima while using inexpensive calculations with moderate statistical uncertainty. We demonstrate the applicability of the algorithm by minimizing the energy of the H2O-OH- complex and showing that the structural minima from quantum Monte Carlo calculations affect the qualitative behavior of the potential energy surface substantially.

    2013-01-01

    We present a scheme for the parallelization of quantum Monte Carlo on graphical processing units, focusing on bosonic systems and variational Monte Carlo. We use asynchronous execution schemes with shared memory persistence, and obtain an excellent acceleration. Comparing with single core execution, GPU-accelerated code runs over x100 faster. The CUDA code is provided along with the package that is necessary to execute variational Monte Carlo for a system representing liquid helium-4. The program was benchmarked on several models of Nvidia GPU, including Fermi GTX560 and M2090, and the latest Kepler architecture K20 GPU. Kepler-specific optimization is discussed.

    The Tulum Valley aquifer vulnerability and its correlation with the behavior of hydro chemical parameters related to new urban neighborhoods and uncontrolled waste disposal are discussed. A high vulnerability to contamination by substances solved in the recharge water at the San Juan river shore is estimated. A fast transport rate due to the high permeability is foreseen, as well as the existence of contamination sources related to waste disposals and populations without a sewer system. The results show that the mentioned populations and waste disposal sites are located at vulnerable zones of the area. A higher concentration of nitrates and nitrites is observed at the Southeast, due to the short permanency period of the water in the system, and to the reconcentration in zones with less permeable levels.

    Plasma behaviours are very complicated and the analyses are generally difficult. However, when the collisional processes play an important role in the plasma behaviour, the Monte Carlo method is often employed as a useful tool. For examples, in neutral particle injection heating (NBI heating), electron or ion cyclotron heating, and alpha heating, Coulomb collisions slow down high energetic particles and pitch angle scatter them. These processes are often studied by the Monte Carlo technique and good agreements can be obtained with the experimental results. Recently, Monte Carlo Method has been developed to study fast particle transports associated with heating and generating the radial electric field. Further it is applied to investigating the neoclassical transport in the plasma with steep gradients of density and temperatures which is beyong the conventional neoclassical theory. In this report, we briefly summarize the researches done by the present authors utilizing the Monte Carlo method. (author)

  3. Smart detectors for Monte Carlo radiative transfer

    CERN Document Server

    Baes, Maarten

    2008-01-01

    Many optimization techniques have been invented to reduce the noise that is inherent in Monte Carlo radiative transfer simulations. As the typical detectors used in Monte Carlo simulations do not take into account all the information contained in the impacting photon packages, there is still room to optimize this detection process and the corresponding estimate of the surface brightness distributions. We want to investigate how all the information contained in the distribution of impacting photon packages can be optimally used to decrease the noise in the surface brightness distributions and hence to increase the efficiency of Monte Carlo radiative transfer simulations. We demonstrate that the estimate of the surface brightness distribution in a Monte Carlo radiative transfer simulation is similar to the estimate of the density distribution in an SPH simulation. Based on this similarity, a recipe is constructed for smart detectors that take full advantage of the exact location of the impact of the photon pack...

  8. [The examination of men's wits by Juan Huarte de San Juan, and the dawn of the neurobiology of intelligence in the Spanish renaissance].

    Science.gov (United States)

    Martín-Araguz, A; Bustamante-Martínez, C

    The Spanish renaissance doctor Juan Huarte de San Juan (1529-1588) was the author of a unique and immortal work, The Examination of Men's Wits, the edition princeps of which was printed in Baeza in 1575. Since then it has been reprinted at least 80 times and translated into seven languages, which makes it the most influential Spanish contribution to medicine ever published. In this paper we review the unjustly little-known figure of Huarte as the founder of Neuropsychology, and we also analyse his works from a historical and neuroscientific point of view. Huarte's writings deal with the problem of the organic relations between the brain and understanding, and accept the possible influences exerted by temper on the will within the field of the Neurobiology of Intelligence. Thus, over four centuries ago Huarte became the founder of Differential or Physiological Psychology, Neuropsychology, Eugenics and Career Guidance. Huarte's work not only played a fundamental role in the history and development of the body of neuroscientific knowledge, but has also been a clear (although not always cited) influence on scientists, philosophers and men of letters such as Alarcón, Bacon, Cabanis, Cervantes (whose Don Quixote was inspired by him), Charron, Chomsky, Gall, Goethe, Hume, Kant, Kretchmer, Lessing, Lope de Vega, Montaigne, Montesquieu, Nietzsche, Quevedo, Rousseau, Schopenhauer, Thomasius, Tirso de Molina and Ziegler. In the middle of the 16th century, Huarte and his Examination of Men's Wits, together with the works of the naturalist philosophers Gómez Pereira (Antoniana Margarita, 1554) and Miguel Sabuco (New Philosophy, 1587), constituted the prestigious triumvirate of Spanish Renaissance scholars who, for the first time in history, contemplated the workings of the brain from a point of view that had more to do with science than the supernatural.

    MSC Subject Classification: 65C05, 65U05. Monte Carlo methods are a powerful tool in many fields of mathematics, physics and engineering. It is known, that these methods give statistical estimates for the functional of the solution by performing random sampling of a certain chance variable whose mathematical expectation is the desired functional. Monte Carlo methods are methods for solving problems using random variables. In the book [16] edited by Yu. A. Shreider one can find the followin...

    2001-01-01

    Path integral Monte Carlo (PIMC) simulations have become an important tool for the investigation of the statistical mechanics of quantum systems. I discuss some of the history of applying the Monte Carlo method to non-relativistic quantum systems in path-integral representation. The principle feasibility of the method was well established by the early eighties, a number of algorithmic improvements have been introduced in the last two decades.

    The authors present a brief description of a formalism for modeling point defect diffusion in crystalline systems using a Monte Carlo technique. The main approximations required to construct a practical scheme are briefly discussed, with special emphasis on the proper treatment of charged dopants and defects. This is followed by tight binding calculations of the diffusion barrier heights for charged vacancies. Finally, an application of the kinetic lattice Monte Carlo method to vacancy diffusion is presented.

    Full Text Available RESUMEN: A partir de una reflexión inicial sobre el fenómeno de las conmemoraciones, el autor se plantea las causas por las que el tercer centenario de la muerte de Carlos II no dará lugar a ninguna conmemoración. Con independencia de las valoraciones de todo tipo que puedan hacerse de dichas celebraciones, lo cierto es que, en este caso, tal vez hubieran permitido acercar al gran público a uno de los monarcas peor conocidos y menos valorados de la historia de España. Lo más grave, sin embargo, es que la sombra del desconocimiento y el juicio peyorativo se extienden también sobre todo su reinado. Las investigaciones sobre aquel periodo, sin embargo, a pesar de que no abundan, muestran una realidad bastante distinta, en la que la decadencia y la pérdida de la hegemonía internacional convivieron con importantes iniciativas y realizaciones políticas, tanto en el ámbito interno de la Monarquía, como en las relaciones internacionales.ABSTRACT: Parting from an initial reflection about the phenomenon of commemorations, the author ponders the causes for which the third centenary of Charles IFs death will not be the subjet of any celebrations. Besides any evaluations which might be made of these events, the truth is that, perhaps, in this case, a commemoration would have brought the general public closer to one of the least known and worst valued monarchs in the history of Spain. What is more serious, however, is the fact that the shadow of ignorance and pejorative judgement extend also over the entirety of his reign. Though scarce, research about this period shows a very different reality, in wich decadence and the loss of international hegemony cohabitated with important political initiatives and achievements, both in the monarchy's internal domain and in the international arena.

  18. Error in Monte Carlo, quasi-error in Quasi-Monte Carlo

    CERN Document Server

    Kleiss, R H

    2006-01-01

    While the Quasi-Monte Carlo method of numerical integration achieves smaller integration error than standard Monte Carlo, its use in particle physics phenomenology has been hindered by the abscence of a reliable way to estimate that error. The standard Monte Carlo error estimator relies on the assumption that the points are generated independently of each other and, therefore, fails to account for the error improvement advertised by the Quasi-Monte Carlo method. We advocate the construction of an estimator of stochastic nature, based on the ensemble of pointsets with a particular discrepancy value. We investigate the consequences of this choice and give some first empirical results on the suggested estimators.

  19. Dengue Fever Trends and Climate Change in San Juan, Puerto Rico

    Climate change has important implications for public health. We developed and tested the hypothesis that conditions for dengue fever transmission in San Juan (Puerto Rico, USA) are becoming favorable as a result of meteorological drivers being modified with climate change. Sea level pressure, mean sea level (MSL), wind, sea surface temperature (SST), air surface temperature (AST), rainfall, and confirmed dengue cases were variables examined over the past 30 years, or longer for some variables. Statistical tools used included Principal Component Analysis, Pearson correlation coefficient, Mann-Kendall trend tests, and logistic regressions. Results show that dry days are increasing and that wet days are decreasing. MSL is steadily increasing, which increases the risk of dengue cases along the coast, as the perimeter of the San Juan Bay estuary expands and the shoreline moves inland. Warming is evident in both SST and AST. Maximum and minimum air surface temperature extremes have also increased. Incidence of dengue is accelerating along with environmental change. For example, between 2000-2011, dengue transmission increased by a factor of 3.4 (95% CI: 1.9-6.1) for each 1ºC increase in SST. Between 2007 and 2011, this risk factor increased to 5.2 (95% CI: 1.9-13.9) for every 1ºC increase in SST. An important but difficult to examine problem is how social and economic factors affect such dengue fever transmission rates in light of environmental change. A concern is that the patterns observed in San Juan are representative of potential incidence of dengue virus in other parts of the island of Puerto Rico and in other Caribbean nations. These results help understand patterns of disease spreading, and allow public health officials to evaluate scenarios and interventions intended to mitigate the impacts of climate change.

  20. A heat vulnerability index to improve urban public health management in San Juan, Puerto Rico

    Increased frequency and length of high heat episodes are leading to more cardiovascular issues and asthmatic responses among the population of San Juan, the capital of the island of Puerto Rico, USA. An urban heat island effect, which leads to foci of higher temperatures in some urban areas, can raise heat-related mortality. The objective of this research is to map the risk of high temperature in particular locations by creating heat maps of the city of San Juan. The heat vulnerability index (HVI) maps were developed using images collected by satellite-based remote sensing combined with census data. Land surface temperature was assessed using images from the Thermal Infrared Sensor flown on Landsat 8. Social determinants (e.g., age, unemployment, education and social isolation, and health insurance coverage) were analyzed by census tract. The data were examined in the context of land cover maps generated using products from the Puerto Rico Terrestrial Gap Analysis Project (USDA Forest Service). All variables were set in order to transform the indicators expressed in different units into indices between 0 and 1, and the HVI was calculated as sum of score. The tract with highest index was considered to be the most vulnerable and the lowest to be the least vulnerable. Five vulnerability classes were mapped (very high, high, moderate, low, and very low). The hottest and the most vulnerable tracts corresponded to highly built areas, including the Luis Munoz International Airport, seaports, parking lots, and high-density residential areas. Several variables contributed to increased vulnerability, including higher rates of the population living alone, disabilities, advanced age, and lack of health insurance coverage. Coolest areas corresponded to vegetated landscapes and urban water bodies. The urban HVI map will be useful to health officers, emergency preparedness personnel, the National Weather Service, and San Juan residents, as it helps to prepare for and to mitigate

  1. Marine Biodiversity in Juan Fernández and Desventuradas Islands, Chile: Global Endemism Hotspots.

    The Juan Fernández and Desventuradas islands are among the few oceanic islands belonging to Chile. They possess a unique mix of tropical, subtropical, and temperate marine species, and although close to continental South America, elements of the biota have greater affinities with the central and south Pacific owing to the Humboldt Current, which creates a strong biogeographic barrier between these islands and the continent. The Juan Fernández Archipelago has ~700 people, with the major industry being the fishery for the endemic lobster, Jasus frontalis. The Desventuradas Islands are uninhabited except for a small Chilean military garrison on San Félix Island. We compared the marine biodiversity of these islands across multiple taxonomic groups. At San Ambrosio Island (SA), in Desventuradas, the laminarian kelp (Eisenia cokeri), which is limited to Desventuradas in Chile, accounted for >50% of the benthic cover at wave exposed areas, while more sheltered sites were dominated by sea urchin barrens. The benthos at Robinson Crusoe Island (RC), in the Juan Fernández Archipelago, comprised a diverse mix of macroalgae and invertebrates, a number of which are endemic to the region. The biomass of commercially targeted fishes was >2 times higher in remote sites around RC compared to sheltered locations closest to port, and overall biomass was 35% higher around SA compared to RC, likely reflecting fishing effects around RC. The number of endemic fish species was extremely high at both islands, with 87.5% of the species surveyed at RC and 72% at SA consisting of regional endemics. Remarkably, endemics accounted for 99% of the numerical abundance of fishes surveyed at RC and 96% at SA, which is the highest assemblage-level endemism known for any individual marine ecosystem on earth. Our results highlight the uniqueness and global significance of these biodiversity hotspots exposed to very different fishing pressures.

  2. Community-based enterprises and the commons: The case of San Juan Nuevo Parangaricutiro, Mexico

    Full Text Available Commons scholarship has tended to focus on the administration and use of commons by individuals and households and less so on collective enterprises that extract, transform and market what they harvest from the commons. In this paper, we consider Nuevo San Juan, a Mexican case that is well known in the community forestry and commons literature. In San Juan, indigenous community members who hold the rights for the commons are also the members of the enterprise that transforms and markets goods from the commons. We argue that such a strategy is one way to confront internal and external pressures on a commons. We draw upon the transcripts of 40 interviews undertaken during 2006 which are analyzed using a framework developed from the social, community-based and indigenous enterprise literature. Our goal was to utilize this framework to analyze the San Juan Forest Enterprise and understand its emergence and formation as a long-standing community-based enterprise that intersects with a commons, and thereby identify factors that increase chances of success for community enterprises. We found that by starting from the community-based and indigenous enterprise literature and using that literature to engage with thinking on commons, it was possible to consider the enterprise from the perspective of a regulatory framework rather than from the poles of dependency and modernization theories in which much commons work has been based. Enterprise and commons intersect when both are guided by core cultural values and the enterprise can become a new site for the creation of social and cultural cohesion. We also found that there were a number of necessary conditions for commons-based community-enterprises to retain internal and external legitimacy, namely: (1 leadership representative of the broad social mission rooted in the customary institutions, values and norms of the community; (2 accountability of enterprise leaders to the memberships they represent; and (3

    Full Text Available The aim of this paper is to explain the reasons for Juan Rejano to have removed his book Canciones de la paz (Songs for the Peace, 1955 from his first almost complete poems collection, Alas de tierra (Wings of Earth, 1975, and to modify it in his last «collected poems», La mirada del hombre (The Man’s Sight, 1978. In this paper, the circumstances under which the book was written will be analysed, these being linked to the World Movement for Peace and being deeply influenced by the P.C.E. (Spanish Communist Party exhortations. The study of textual variants, deleted poems and new assignments in finished poems reveals that Juan Rejano feels uncomfortable with the combative voice of this part of his work as the instrument to reveal the ugliest side in contemporary life. In addition, this book, intended to be written for children, does not fit in young readers literature.Este artículo trata de dar cuenta de las razones que llevaron a Juan Rejano a eliminar el libro Canciones de la paz (1955 de su primera gran recopilación, Alas de tierra (1975, y a modificarlo sustancialmente en su última suma poética, La mirada del hombre (1978. Con el análisis de las circunstancias en que nació el libro, vinculado al Movimiento Mundial por la Paz e influenciado por las consignas del PCE, y con el estudio de variantes, poemas eliminados y poemas reubicados, podemos aventurar que Rejano no se sentía cómodo con la parte más combativa del libro y con la que presentaba la faceta más sombría de la realidad contemporánea, además de que no cabía el adoctrinamiento en una escritura explícitamente dirigida a los niños.

  6. Regional Studies Program. Biological aspects of surface coal mine reclamation, Black Mesa and San Juan Basin

    Energy Technology Data Exchange (ETDEWEB)

    Green, B.B.

    1977-08-01

    This report discusses case study data on surface mine reclamation accumulated at selected mines in the Southwest, specifically the Black Mesa Mine in Arizona and the Navajo Mine located south of Fruitland, New Mexico, in the San Juan Basin. Experimental results have made it apparent that reclamation of disturbed lands cannot begin and end with planting seed. The report therefore considers hydrologic, edaphic, and biotic factors, as well as land use and management, as important aspects of land reclamation. Recommendations are made to initiate, broaden, and intensify research studies in plant succession, productivity, species selection, and attendant soil characteristics, along with grazing practices and land use potential.

    The authors analyze single-well seismic data from the San Juan basin in Northwest New Mexico. The consistently observable events are tube-waves: direct, reflected and multiple tube-waves can be explained by the formation properties and survey geometry except for an anomalous zone with low velocity, high amplitude and horizontal polarization. To aid the data analysis, forward modeling using a variable-grid finite-difference parallel code is performed. The numerical result confirms the identified events in the field observations.

    Unconsolidated volcaniclastic glass deposits on the flanks of Axial Seamount, a caldera system situated on the Juan de Fuca Ridge in the NE Pacific Ocean, demonstrate the occurrence of explosive events, in addition to effusive activity. The variety of produced glass fragments ranges from various angular forms to thin deep-sea limu o Pele, with dominantly moderately fractionated to occasionally primitive MOR basalt composition. A model involving the collapse of a magmatic foam layer may account for the observed spectrum of glass fragments.

    Images the Juan de Fuca plate in southern Oregon using seismic tomography. P wave travel time residuals from a 366-km-long seismic array operated in southern Oregon in 1982 are inverted. The southeast striking array extended from the Coast ranges to the Modoc Plateau and crossed the High Cascades at Crater Lake, Oregon. Three features under the array were imaged: one high-velocity zone and two low-velocity zones. The high-velocity zone is 3-4% faster than the surrounding upper mantle. It dips steeply at 65?? to the east beneath the Cascade Range and extends down to at least 200 km. It is proposed that this high-velocity feature is subducted Juan de Fuca plate. Two low-velocity zones were also imaged, both of which are 3-4% slower than the surrounding earth structure. The southeastern low-velocity zone may be caused by partially molten crust underlying the Crater Lake volcano region. -from Authors

    Full Text Available In the years 1970-1972, the novelist Juan Goytisolo published several studies and translations on the work of José María Blanco White, which represent a key moment in the recovery of that forgotten writer for the modern Spanish culture. The argument made in this essay is that the consciously identifying strategy applied by Goytisolo on Blanco White, in order to define a Spanish intellectual tradition throughout the centuries, marked by exile and dissent, is in fact a deformation of the figure and thought of the writer from Seville. Blanco White’s reception in Spain, however, has been conditioned by that reading.En torno a los años 1970-1972 el novelista Juan Goytisolo publica varios estudios y traducciones sobre la obra de José María Blanco White, que suponen un momento clave en la recuperación de ese olvidado escritor para la moderna cultura española.

La recepción de Blanco White en España ha quedado, sin embargo, condicionada por esa lectura.

  10. Application of an area of review variance methodology to the San Juan Basin, New Mexico

    Energy Technology Data Exchange (ETDEWEB)

    Dunn-Norman, S.; Warner, D.L.; Koederitz, L.F.; Laudon, R.C.

    1995-12-01

    When the Underground Injection Control (UIC) Regulations were promulgated in 1980, existing Class II Injection wells operating at the time were excluded from Area of Review (AOR) requirements. EPA has expressed its intent to revise the regulations to include the requirement for AOR`s for such wells, but it is expected that oil and gas producing states will be allowed to adopt a variance strategy for these wells. An AOR variance methodology has been developed under sponsorship of the American Petroleum Institute. The general concept of the variance methodology is a systematic evaluation of basic variance criteria that were agreed to by a Federal Advisory Committee. These criteria include absence of USDWs, lack of positive flow potential from the petroleum reservoir into the overlying USDWs, mitigating geological factors, and other evidence. The AOR variance methodology has been applied to oilfields in the San Juan Basin, New Mexico. This paper details results of these analyses, particularly with respect to the opportunity for variance for injection fields in the San Juan Basin.

  11. Geologic controls on open-hole cavity completions in the San Juan basin

    Energy Technology Data Exchange (ETDEWEB)

    Kelso, B.S. (Advanced Resources International, Inc., Lakewood, CO (United States))

    1994-04-01

    The success of open-cavity-completed wells is measured (1) by how well mechanically the cavity is created, which results in a higher degree of completion efficiency; and (2) by production success, whereby production rates are improved relative to other completion techniques. Open-hole cavitation is highly successful in the San Juan basin fairway, but the technique has not been successful in other areas. Outside the fairway, particularly to the south, operators have not achieved mechanical success with cavity completions. To explain the change in permeability across the southern fairway boundary, an hypothesis is proposed that involves the presence of a northwest-trending basement structure, such as a fault or fault zone. Episodic post-Fruitland movement on the northeastern limb of the structure could have enhanced the fracturing of the coal seams, resulting in higher permeabilities and the higher productivity levels of both cavity and fracture-stimulated wells. Based on the San Juan basin data reviewed, it appears that a combination of adequate permeability, overpressuring, and coal rank of high-volatile A bituminous are required for mechanical success of cavity completions. Although the level of permeability is not quantified, it is the author's opinion that at least 5 md is required. High production rates from cavity-completed wells are a function of better completion efficiency, whereby the wellbore is linked to favorable permeability settings. 5 refs., 10 figs.

  12. Sub-Seafloor Carbon Dioxide Storage Potential on the Juan de Fuca Plate, Western North America

    Energy Technology Data Exchange (ETDEWEB)

    Jerry Fairley; Robert Podgorney

    2012-11-01

    The Juan de Fuca plate, off the western coast of North America, has been suggested as a site for geological sequestration of waste carbon dioxide because of its many attractive characteristics (high permeability, large storage capacity, reactive rock types). Here we model CO2 injection into fractured basalts comprising the upper several hundred meters of the sub-seafloor basalt reservoir, overlain with low-permeability sediments and a large saline water column, to examine the feasibility of this reservoir for CO2 storage. Our simulations indicate that the sub-seafloor basalts of the Juan de Fuca plate may be an excellent CO2 storage candidate, as multiple trapping mechanisms (hydrodynamic, density inversions, and mineralization) act to keep the CO2 isolated from terrestrial environments. Questions remain about the lateral extent and connectivity of the high permeability basalts; however, the lack of wells or boreholes and thick sediment cover maximize storage potential while minimizing potential leakage pathways. Although promising, more study is needed to determine the economic viability of this option.

  13. Increasing coal absolute permeability in the San Juan basin Fruitland formation

    Energy Technology Data Exchange (ETDEWEB)

    Mavor, M.J.; Vaughn, J.E. [Society of Petroleum Engineers, Richardson, TX (United States)

    1998-10-01

    Recently measured data show that the absolute permeability of coal natural fracture is increasing significantly with continued gas production in the San Juan basin Fruitland formation. This phenomenon caused gas-production rates to be many times greater than expected from early production history. The phenomenon also caused producing bottomhole pressures to increase when gas rates were constant, opposite from that expected from conventional applications of Darcy`s law. The increase in absolute permeability caused by gas desorption has been measured on cores but, until recently, there was no verification that this phenomenon occurs in situ. Palmer and Mansoori (P & M) presented a new theory and showed how this theory matched gas- and water-production rates and estimated bottomhole-pressure data for a high-deliverability San Juan basin Fruitland formation coal-gas well. However, Palmer and Mansoor had no transient pressure data to support in-situ permeability changes. This paper documents data from drillstem tests and shut-in tests with analyses thereof and additional production-rate and pressure behaviors that support the P & M theory.

  14. CO{sub 2} sequestration in an unmineable coalbed - San Juan Basin, Colorado, USA

    Erickson, D.; Jensen, J.R. [BP Amoco, Sunbury-on-Thames (United Kingdom)

    2001-07-01

    BP Amoco (BPA) is investigating the sequestration of approximately 464 tonnes per day of vented CO{sub 2} from gas processing plant by injecting the CO{sub 2} into a non-mineable natural gas producing coal in the Colorado portion of the San Juan Basin. Removed CO{sub 2} from this production will be re-injected into the coalbed for sequestration. BPA has concentrated efforts on utilizing nitrogen to enhance the recovery of methane from coals and currently operates the largest and most significant project of its kind. On a pilot basis, CO{sub 2} sequestration, as an enhanced recovery process for Fruitland coals, has also been undertaken in the San Juan Basin (SJB). The two gases behave differently in coals. CO{sub 2} is readily adsorbed on the coal and therefore displaces the methane whereas the nitrogen strips the methane from the coals by reducing the partial pressure of the methane. Injection, production and reservoir data will be used to evaluate the success of the CO{sub 2} sequestration. BPA will use its proprietary GCOMP Reservoir Model to investigate the flow and adsorption of CO{sub 2}, simulate the process, compare field results with model predictions, and adjust the model to better match actual field performance. Preliminary simulations indicate that some incremental methane production will be recovered, while sequestering nearly all of the injected CO{sub 2} in the coals seams. 3 figs.

    A common mode of speciation in oceanic islands is by anagenesis, wherein an immigrant arrives and through time transforms by mutation, recombination, and drift into a morphologically and genetically distinct species, with the new species accumulating a high level of genetic diversity. We investigate speciation in Drimys confertifolia, endemic to the two major islands of the Juan Fernández Archipelago, Chile, to determine genetic consequences of anagenesis, to examine relationships among populations of D. confertifolia and the continental species D. winteri and D. andina, and to test probable migration routes between the major islands. Population genetic analyses were conducted using AFLPs and nuclear microsatellites of 421 individuals from 42 populations from the Juan Fernández islands and the continent. Drimys confertifolia shows a wide genetic variation within populations on both islands, and values of genetic diversity within populations are similar to those found within populations of the continental progenitor. The genetic results are compatible with the hypothesis of high levels of genetic variation accumulating within anagenetically derived species in oceanic islands, and with the concept of little or no geographical partitioning of this variation over the landscape. Analysis of the probability of migration within the archipelago confirms colonization from the older island, Robinson Crusoe, to the younger island Alejandro Selkirk.

    Dinosaur footprints were traced at San Juan Raya, an important site in Mexico, a world fossil site. This site is found at South-west of the State of Puebla, within the Biosphere Reserve of Tehuacan-Cuitcatlán, to the southwest of the Tehuacan valley. These footprints were recorded by tracing them on transparent paper at Barranca Agua Nueva, at point 18°18.56´N 97°37´W. Using Jacob´s staff a stratigraphic register was generated from 50 m ascending and descending in stratigraphically direction from the bed where footprints were founded. Bivalbes, nerineas, shell fragments, and trigonias were founded in this sequence as well as cross bedding of clays and fine grain sand, some which display ripples. Fifty two footprints were recorded and five different tracks identified, observing two different sizes. The tracks of dinosaur footprints present the common Teropode ichnites. The succession where dinosaur footprints have been found, are interpreted as a peritidal environment. This investigation contributes to an eco-tourism project of San Juan Raya.

    Full Text Available Juan Gelman is generally considered by critics to be one of the most important poets of modern Argentina. Born in Buenos Aires in 1930 from Russian-Jewish parents, he published his first collection of poems (Violín y otras cuestiones in 1956. He is a member of the generación del 60, made up of intellectuals influenced in their critical realism by the charisma of Raúl González Tuñón, forerunner of Argentina’s social and political poetry. This group was politically very active, as demonstrated by their experimental language and iconoclastic lyricism. Gelman’s later life was marked by his exile in the wake of the 1976 dictatorship, and by the desaparición of his son Marcelo Ariel, his daughter-in-law Claudia and his grand-daughter Andrea (born in prison. Since then, it was impossible for Juan Gelman to separate his personal plight from Argentina’s historical-political situation, and his poetry became more and more intimate and lyrical, marked by human drama. La junta luz, the author’s only theatre play, was written and published in this second phase.

    Petruzielo, F R; Umrigar, C J

    2012-01-01

    A quantum Monte Carlo study of the atomization energies for the G2 set of molecules is presented. Basis size dependence of diffusion Monte Carlo atomization energies is studied with a single determinant Slater-Jastrow trial wavefunction formed from Hartree-Fock orbitals. With the largest basis set, the mean absolute deviation from experimental atomization energies for the G2 set is 3.0 kcal/mol. Optimizing the orbitals within variational Monte Carlo improves the agreement between diffusion Monte Carlo and experiment, reducing the mean absolute deviation to 2.1 kcal/mol. Moving beyond a single determinant Slater-Jastrow trial wavefunction, diffusion Monte Carlo with a small complete active space Slater-Jastrow trial wavefunction results in near chemical accuracy. In this case, the mean absolute deviation from experimental atomization energies is 1.2 kcal/mol. It is shown from calculations on systems containing phosphorus that the accuracy can be further improved by employing a larger active space.

    Arsenic (As) speciation in surface and groundwater from two provinces in Argentina (San Juan and La Pampa) was investigated using solid phase extraction (SPE) cartridge methodology with comparison to total arsenic concentrations. A third province, Río Negro, was used as a control to the study. Strong cation exchange (SCX) and strong anion exchange (SAX) cartridges were utilised in series for the separation and preservation of arsenite (As(III)), arsenate (As(V)), monomethylarsonic acid (MA(V)) and dimethylarsinic acid (DMA(V)). Samples were collected from a range of water outlets (rivers/streams, wells, untreated domestic taps, well water treatment works) to assess the relationship between total arsenic and arsenic species, water type and water parameters (pH, conductivity and total dissolved solids, TDS). Analysis of the waters for arsenic (total and species) was performed by inductively coupled plasma mass spectrometry (ICP-MS) in collision cell mode. Total arsenic concentrations in the surface and groundwater from Encon and the San José de Jáchal region of San Juan (north-west Argentina within the Cuyo region) ranged from 9 to 357 μg l(-1) As. Groundwater from Eduardo Castex (EC) and Ingeniero Luiggi (LU) in La Pampa (central Argentina within the Chaco-Pampean Plain) ranged from 3 to 1326 μg l(-1) As. The pH range for the provinces of San Juan (7.2-9.7) and La Pampa (7.0-9.9) are in agreement with other published literature. The highest total arsenic concentrations were found in La Pampa well waters (both rural farms and pre-treated urban sources), particularly where there was high pH (typically > 8.2), conductivity (>2,600 μS cm(-1)) and TDS (>1,400 mg l(-1)). Reverse osmosis (RO) treatment of well waters in La Pampa for domestic drinking water in EC and LU significantly reduced total arsenic concentrations from a range of 216-224 μg l(-1) As to 0.3-0.8 μg l(-1) As. Arsenic species for both provinces were predominantly As(III) and As(V). As

  1. Random Numbers and Monte Carlo Methods

    Science.gov (United States)

    Scherer, Philipp O. J.

    Many-body problems often involve the calculation of integrals of very high dimension which cannot be treated by standard methods. For the calculation of thermodynamic averages Monte Carlo methods are very useful which sample the integration volume at randomly chosen points. After summarizing some basic statistics, we discuss algorithms for the generation of pseudo-random numbers with given probability distribution which are essential for all Monte Carlo methods. We show how the efficiency of Monte Carlo integration can be improved by sampling preferentially the important configurations. Finally the famous Metropolis algorithm is applied to classical many-particle systems. Computer experiments visualize the central limit theorem and apply the Metropolis method to the traveling salesman problem.

    Full Text Available Sequential Monte Carlo methods are a very general class of Monte Carlo methodsfor sampling from sequences of distributions. Simple examples of these algorithms areused very widely in the tracking and signal processing literature. Recent developmentsillustrate that these techniques have much more general applicability, and can be appliedvery eectively to statistical inference problems. Unfortunately, these methods are oftenperceived as being computationally expensive and dicult to implement. This articleseeks to address both of these problems.A C++ template class library for the ecient and convenient implementation of verygeneral Sequential Monte Carlo algorithms is presented. Two example applications areprovided: a simple particle lter for illustrative purposes and a state-of-the-art algorithmfor rare event estimation.

    Ormand, W.E.

    1995-03-01

    The formalism for the auxiliary-field Monte Carlo approach to the nuclear shell model is presented. The method is based on a linearization of the two-body part of the Hamiltonian in an imaginary-time propagator using the Hubbard-Stratonovich transformation. The foundation of the method, as applied to the nuclear many-body problem, is discussed. Topics presented in detail include: (1) the density-density formulation of the method, (2) computation of the overlaps, (3) the sign of the Monte Carlo weight function, (4) techniques for performing Monte Carlo sampling, and (5) the reconstruction of response functions from an imaginary-time auto-correlation function using MaxEnt techniques. Results obtained using schematic interactions, which have no sign problem, are presented to demonstrate the feasibility of the method, while an extrapolation method for realistic Hamiltonians is presented. In addition, applications at finite temperature are outlined.

    We investigate the inclusion of variable spins in electronic structure quantum Monte Carlo, with a focus on diffusion Monte Carlo with Hamiltonians that include spin-orbit interactions. Following our previous introduction of fixed-phase spin-orbit diffusion Monte Carlo, we thoroughly discuss the details of the method and elaborate upon its technicalities. We present a proof for an upper-bound property for complex nonlocal operators, which allows for the implementation of T-moves to ensure the variational property. We discuss the time step biases associated with our particular choice of spin representation. Applications of the method are also presented for atomic and molecular systems. We calculate the binding energies and geometry of the PbH and Sn2 molecules, as well as the electron affinities of the 6p row elements in close agreement with experiments.

    Simulation affects our life every day through our interactions with the automobile, airline and entertainment industries, just to name a few. The use of simulation in drug development is relatively new, but its use is increasing in relation to the speed at which modern computers run. One well known example of simulation in drug development is molecular modelling. Another use of simulation that is being seen recently in drug development is Monte Carlo simulation of clinical trials. Monte Carlo simulation differs from traditional simulation in that the model parameters are treated as stochastic or random variables, rather than as fixed values. The purpose of this paper is to provide a brief introduction to Monte Carlo simulation methods.

    We present the public release of the Bayesian sampling algorithm for cosmology, CosmoPMC (Cosmology Population Monte Carlo). CosmoPMC explores the parameter space of various cosmological probes, and also provides a robust estimate of the Bayesian evidence. CosmoPMC is based on an adaptive importance sampling method called Population Monte Carlo (PMC). Various cosmology likelihood modules are implemented, and new modules can be added easily. The importance-sampling algorithm is written in C, and fully parallelised using the Message Passing Interface (MPI). Due to very little overhead, the wall-clock time required for sampling scales approximately with the number of CPUs. The CosmoPMC package contains post-processing and plotting programs, and in addition a Monte-Carlo Markov chain (MCMC) algorithm. The sampling engine is implemented in the library pmclib, and can be used independently. The software is available for download at http://www.cosmopmc.info.

  8. Quantum speedup of Monte Carlo methods.

    Montanaro, Ashley

    2015-09-08

    Monte Carlo methods use random sampling to estimate numerical quantities which are hard to compute deterministically. One important example is the use in statistical physics of rapidly mixing Markov chains to approximately compute partition functions. In this work, we describe a quantum algorithm which can accelerate Monte Carlo methods in a very general setting. The algorithm estimates the expected output value of an arbitrary randomized or quantum subroutine with bounded variance, achieving a near-quadratic speedup over the best possible classical algorithm. Combining the algorithm with the use of quantum walks gives a quantum speedup of the fastest known classical algorithms with rigorous performance bounds for computing partition functions, which use multiple-stage Markov chain Monte Carlo techniques. The quantum algorithm can also be used to estimate the total variation distance between probability distributions efficiently.

  9. Adiabatic optimization versus diffusion Monte Carlo methods

    Jarret, Michael; Jordan, Stephen P.; Lackey, Brad

    2016-10-01

    Most experimental and theoretical studies of adiabatic optimization use stoquastic Hamiltonians, whose ground states are expressible using only real nonnegative amplitudes. This raises a question as to whether classical Monte Carlo methods can simulate stoquastic adiabatic algorithms with polynomial overhead. Here we analyze diffusion Monte Carlo algorithms. We argue that, based on differences between L1 and L2 normalized states, these algorithms suffer from certain obstructions preventing them from efficiently simulating stoquastic adiabatic evolution in generality. In practice however, we obtain good performance by introducing a method that we call Substochastic Monte Carlo. In fact, our simulations are good classical optimization algorithms in their own right, competitive with the best previously known heuristic solvers for MAX-k -SAT at k =2 ,3 ,4 .

    2017-01-01

    Monte Carlo simulation is an unbiased numerical tool for studying classical and quantum many-body systems. One of its bottlenecks is the lack of a general and efficient update algorithm for large size systems close to the phase transition, for which local updates perform badly. In this Rapid Communication, we propose a general-purpose Monte Carlo method, dubbed self-learning Monte Carlo (SLMC), in which an efficient update algorithm is first learned from the training data generated in trial simulations and then used to speed up the actual simulation. We demonstrate the efficiency of SLMC in a spin model at the phase transition point, achieving a 10-20 times speedup.

    The San Juan sag, concealed by the vast San Juan volcanic field of south-central Colorado, has only recently benefited from oil and gas wildcat drilling and evaluations. Sound geochemical analyses and maturation modeling are essential elements for successful exploration and development. Oil has been produced in minor quantities from an Oligocene sill in the Mancos Shale within the sag, and major oil and gas production occurs from stratigraphically equivalent rocks in the San Juan basin to the southwest and in the Denver basin to the northeast. The objectives of this study were to identify potential source rocks, assess thermal maturity, and determine hydrocarbon-source bed relationships. Source rocks are present in the San Juan sag in the upper and lower Mancos Shale (including the Niobrara Member), which consists of about 666 m (2184 ft) of marine shale with from 0.5 to 3.1 wt. % organic carbon. Pyrolysis yields (S{sub 1} + S{sub 2} = 2000-6000 ppm) and solvent extraction yields (1000-4000 ppm) indicate that some intervals within the Mancos Shale are good potential source rocks for oil, containing type II organic matter, according to Rock-Eval pyrolysis assay.

  8. Variation in the mitochondrial control region in the Juan Fernández fur seal (Arctocephalus philippii).

    2000-01-01

    The Juan Fernandez fur seal (Arctocephalus philippii was allegedly extremely abundant, numbering as many as 4 million prior to sealing which continued from the late 17th to the late 19th century. By the end of the sealing era the species was thought to be extinct until they were rediscovered at Alejandro Selkirk Island in 1965. Historic records would suggest that the species underwent a substantial population bottleneck as a result of commercial sealing, and from population genetic theory we predicted that the genetic variability in the species would be low. We compared the mtDNA control region sequence from 28 Juan Fernandez fur seals from two islands in the Juan Fernandez Archipelago (Chile). Contrary to expectation, we found that variation in the Juan Fernandez fur seals is not greatly reduced in comparison to other pinniped taxa, especially given the apparent severity of the bottleneck they underwent. We also determined minor, but significantly different haplotype frequencies among the populations on the two islands (Alejandro Selkirk and Robinson Crusoe Islands), but no difference in their levels of variability. Such differences may have arisen stochastically via a recent founder event from Alejandro Selkirk to Robinson Crusoe Island or subsequent genetic drift.

    The objective of the work is to model wind field in the surroundings of the Spanish Antarctic Base (BAE in the following). The need of such a work comes from the necessity of an energy source able to supply the energy demand in the BAE during the Antarctic winter. When the BAE is in operation (in the Antarctic summer) the energy supply comes from a diesel engine. In the Antartic winter the base is closed, but the demand of energy supply is growing up every year because of the increase in the number of technical and scientific machines that remain in the BAE taking different measurements. For this purpose the top of a closed hill called Pico Radio, not perturbed by close obstacles, has been chosen as the better site for the measurements. The measurement station is made up with a sonic an-emometer and a small wind generator to supply the energy needed by the sensors head heating of the anemometer. this way, it will be also used as a proof for the suitability of a wind generator in the new chosen site, under those special climactic conditions.

  14. Parallel Markov chain Monte Carlo simulations.

    Science.gov (United States)

    Ren, Ruichao; Orkoulas, G

    2007-06-07

    With strict detailed balance, parallel Monte Carlo simulation through domain decomposition cannot be validated with conventional Markov chain theory, which describes an intrinsically serial stochastic process. In this work, the parallel version of Markov chain theory and its role in accelerating Monte Carlo simulations via cluster computing is explored. It is shown that sequential updating is the key to improving efficiency in parallel simulations through domain decomposition. A parallel scheme is proposed to reduce interprocessor communication or synchronization, which slows down parallel simulation with increasing number of processors. Parallel simulation results for the two-dimensional lattice gas model show substantial reduction of simulation time for systems of moderate and large size.

    We further study the validity of the Monte Carlo Hamiltonian method .The advantage of the method,in comparison with the standard Monte Carlo Lagrangian approach,is its capability to study the excited states.We consider two quantum mechanical models:a symmetric one V(x)=/x/2;and an asymmetric one V(x)==∞,for x<0 and V(x)=2,for x≥0.The results for the spectrum,wave functions and thermodynamical observables are in agreement with the analytical or Runge-Kutta calculations.

    The precision of Radiosurgery Treatment planning systems is limited by the approximations of their algorithms and by their dosimetrical input data. This fact is especially important in small fields. However, the Monte Carlo methods is an accurate alternative as it considers every aspect of particle transport. In this work an acoustic neurinoma is studied by comparing the dose distribution of both a planning system and Monte Carlo. Relative shifts have been measured and furthermore, Dose-Volume Histograms have been calculated for target and adjacent organs at risk. (orig.)

    2014-01-01

    Monte Carlo simulations are a valuable tool to model the generation, separation, and collection of charges in organic photovoltaics where charges move by hopping in a complex nanostructure and Coulomb interactions between charge carriers are important. We review the Monte Carlo techniques that have been applied to this problem, and describe the results of simulations of the various recombination processes that limit device performance. We show how these processes are influenced by the local physical and energetic structure of the material, providing information that is useful for design of efficient photovoltaic systems.

    1995-12-31

    A library of Monte Carlo subroutines has been developed for the purpose of design of neutron scattering instruments. Using small-angle scattering as an example, the philosophy and structure of the library are described and the programs are used to compare instruments at continuous wave (CW) and long-pulse spallation source (LPSS) neutron facilities. The Monte Carlo results give a count-rate gain of a factor between 2 and 4 using time-of-flight analysis. This is comparable to scaling arguments based on the ratio of wavelength bandwidth to resolution width.

    The past few years have seen considerable progress in algorithmic development for the generation of gauge fields including the effects of dynamical fermions. The Rational Hybrid Monte Carlo (RHMC) algorithm, where Hybrid Monte Carlo is performed using a rational approximation in place the usual inverse quark matrix kernel is one of these developments. This algorithm has been found to be extremely beneficial in many areas of lattice QCD (chiral fermions, finite temperature, Wilson fermions etc.). We review the algorithm and some of these benefits, and we compare against other recent algorithm developements. We conclude with an update of the Berlin wall plot comparing costs of all popular fermion formulations.

    EM算法是近年来常用的求后验众数的估计的一种数据增广算法,但由于求出其E步中积分的显示表达式有时很困难,甚至不可能,限制了其应用的广泛性.而Monte Carlo EM算法很好地解决了这个问题,将EM算法中E步的积分用Monte Carlo模拟来有效实现,使其适用性大大增强.但无论是EM算法,还是Monte Carlo EM算法,其收敛速度都是线性的,被缺损信息的倒数所控制,当缺损数据的比例很高时,收敛速度就非常缓慢.而Newton-Raphson算法在后验众数的附近具有二次收敛速率.本文提出Monte Carlo EM加速算法,将Monte Carlo EM算法与Newton-Raphson算法结合,既使得EM算法中的E步用Monte Carlo模拟得以实现,又证明了该算法在后验众数附近具有二次收敛速度.从而使其保留了Monte Carlo EM算法的优点,并改进了Monte Carlo EM算法的收敛速度.本文通过数值例子,将Monte Carlo EM加速算法的结果与EM算法、Monte Carlo EM算法的结果进行比较,进一步说明了Monte Carlo EM加速算法的优良性.

    The Monte Carlo method has become a fundamental tool for brachytherapy dosimetry mainly because no difficulties associated with experimental dosimetry. In brachytherapy the main handicap of experimental dosimetry is the high dose gradient near the present sources making small uncertainties in the positioning of the detectors lead to large uncertainties in the dose. This presentation will review mainly the procedure for calculating dose distributions around a fountain using the Monte Carlo method showing the difficulties inherent in these calculations. In addition we will briefly review other applications of the method of Monte Carlo in brachytherapy dosimetry, as its use in advanced calculation algorithms, calculating barriers or obtaining dose applicators around.

    KAUST Repository

    2009-03-01

    The stochastic approximation Monte Carlo (SAMC) algorithm has recently been proposed as a dynamic optimization algorithm in the literature. In this paper, we show in theory that the samples generated by SAMC can be used for Monte Carlo integration via a dynamically weighted estimator by calling some results from the literature of nonhomogeneous Markov chains. Our numerical results indicate that SAMC can yield significant savings over conventional Monte Carlo algorithms, such as the Metropolis-Hastings algorithm, for the problems for which the energy landscape is rugged. © 2008 Elsevier B.V.

    The role of remote sensing data as it relates to a three-component land management planning system (geographic information, data base management, and planning model) can be understood only when user requirements are known. Personnel at the San Juan National Forest in southwestern Colorado were interviewed to determine data needs for managing and monitoring timber, rangelands, wildlife, fisheries, soils, water, geology and recreation facilities. While all the information required for land management planning cannot be obtained using remote sensing techniques, valuable information can be provided for the geographic information system. A wide range of sensors such as small and large format cameras, synthetic aperture radar, and LANDSAT data should be utilized. Because of the detail and accuracy required, high altitude color infrared photography should serve as the baseline data base and be supplemented and updated with data from the other sensors.

    RESUMEN

    Se analizó la dinámica del Humedal Juan Amarillo durante el periodo comprendido entre los años 1950-2005. Los resultados muestran que la configuración paisajística del ecosistema ha cambiado notoriamente con una tendencia al incremento en el número, tamaño y tipo de parches. Igualmente se presentan diferencias estructurales importantes entre los diversos periodos de tiempo analizados, ocasionados principalmente por la disminución y desaparición de espejos de agua y el aumento de pasto kikuyo (Pennisetum clandestinum. En cuanto al arreglo espacial de los elementos paisajísticos, no sucedieron cambios importantes en los patrones de distribución espacial de los elementos paisajísticos del humedal. De acuerdo con la dimensión fractal, los elementos del paisaje presentan dos tendencias en cuanto a su complejidad: los elementos introducidos poseen las formas más complejas y los elementos propios del ecosistema tienen formas más regulares. Finalmente, la dinámica del humedal fue modelada con el fin de interpretar cómo las múltiples interacciones entre los elementos paisajísticos han influido en la configuración del humedal a lo largo del tiempo.

    Palabras clave: Humedal Juan Amarillo, estructura, composición, dimensión fractal.


    ABSTRACT

    The dynamics of Juan Amarillos’ wetland were analyzed during 55 year between 1950 and 2005. The results showed that the landscape configuration of the ecosystems has dramatically changed within a trend to increase in number, size, and patch type. Likewise, important structural differences came up between the various periods in question; such differences appear to be related to the reduction and disappearance of the pond and the significant increase of the non native kikuyo grass (Pennisetum clandestinum.

    Hawley, William B.; Allen, Richard M.; Richards, Mark A.

    2016-09-01

    The boundary between Earth’s strong lithospheric plates and the underlying mantle asthenosphere corresponds to an abrupt seismic velocity decrease and electrical conductivity increase with depth, perhaps indicating a thin, weak layer that may strongly influence plate motion dynamics. The behavior of such a layer at subduction zones remains unexplored. We present a tomographic model, derived from on- and offshore seismic experiments, that reveals a strong low-velocity feature beneath the subducting Juan de Fuca slab along the entire Cascadia subduction zone. Through simple geodynamic arguments, we propose that this low-velocity feature is the accumulation of material from a thin, weak, buoyant layer present beneath the entire oceanic lithosphere. The presence of this feature could have major implications for our understanding of the asthenosphere and subduction zone dynamics.

    Potassium-argon dating of five basalts from the three main islands of the Juan Fernandez (or Robinson Crusoe) Islands of Chile in the southeastern Pacific gives ages of 1.01 ± 0.12 and 2.44 ± 0.14 million years for Masafuera 3.79 ± 0.20 and 4.23 ± 0.16 for Masatierra, and 5.8 ± 2.1 for Santa Clara. These ages are much younger than that of the underlying oceanic plate and are consistent with the origin of the island-seamount chain from a mantle hot spot beneath the eastward moving Nazca plate. The young age for the archipelago suggests that speciation within endemic genera has occurred within the past 4 to 5 million years. Endemic genera of apparently more ancient origins, such as Lactoris and Thyrsopteris, have apparently dispersed to the islands and survive refugially.

    Full Text Available In this paper, social protest phenomenon during Juan Manuel Santos’ first term is analyzed using political processes approach to study social movements. During Santos’ administration, free trade agreements and the “mining-energy locomotive” initiatives have spurred protests since they have brought perverse consequences to rural, education, and health sectors. Nonetheless, protests are not explained as a reaction of economic dynamics, but as a complex articulation between a favorable context —produced by the change in style between the previous administration (Uribe 2002-2010 and Santos’ one, hence, creating expectations and opportunities towards protestin —, and the active role of people mobilizing, which is expressed by the shaping of mobilization structures and the creation of novelty frameworks for collective action.

    Recurrent basement faulting is the primary controlling mechanism for aligning and compartmentalizing upper Cretaceous aged tight gas reservoirs of the San Juan and Piceance Basins. Northwest trending structural lineaments that formed in conjunction with the Uncompahgre Highlands have profoundly influenced sedimentation trends and created boundaries for gas migration; sealing and compartmentalizing sedimentary packages in both basins. Fractures which formed over the structural lineaments provide permeability pathways which allowing gas recovery from otherwise tight gas reservoirs. Structural alignments and associated reservoir compartments have been accurately targeted by integrating advanced remote sensing imagery, high resolution aeromagnetics, seismic interpretation, stratigraphic mapping and dynamic structural modelling. This unifying methodology is a powerful tool for exploration geologists and is also a systematic approach to tight gas resource assessment in frontier basins.
