    Millions of custodial suspects waive their Miranda rights each year without the benefit of legal counsel. Miranda understanding, appreciation, and reasoning abilities are essential to courts' acceptance of Miranda waivers (Grisso, 2003; Rogers & Shuman, 2005). The question posed to forensic psychologists and psychiatrists in the disputed Miranda waivers is whether a particular waiver decision was knowing, intelligent, and voluntary. Despite the remarkable development of Miranda research in recent decades, studies have generally focused on understanding and appreciation of Miranda rights, but with comparatively minimal emphasis on Miranda reasoning and attendant waiver decisions. Research on defendants' decisional capacities constitutes a critical step in further developing theoretical and clinical models for Miranda waiver decisions. The current study evaluated Miranda waiver decisions for 80 pretrial defendants from two Oklahoma jails to study systematically how rational decision abilities affect defendants' personal waiver decisions. In stark contrast to what was expected, many defendants were able to identify a rational decisional process in their own legal cases, yet cast such reasoning aside and chose a completely contradictory Miranda waiver decision.

  2. Revenge of tiny Miranda

    1977-01-01

    Reference is made to Dermott and Gold (Nature 267: 590 (1977)) who proposed a resonance model for the rings of Uranus. They assumed that the rings are composed of small particles librating about stable resonances determined by pairs of satellites, either Ariel and Titania or Ariel and Oberon. They dismissed as insignificant resonances involving 'tiny Miranda'. It is reported here that, by a wide margin, the strongest resonances are all associated with Miranda. It is also shown that the hypothesis that the rings are made up of librating particles, whilst original and ingenious, is incorrect. (author)

    This study examined juvenile justice-involved youths' understanding and appreciation of the Miranda warnings' rights to silence and legal counsel using the Miranda Rights Comprehension Instruments (Goldstein, Zelle, & Grisso, 2012). It also examined the relationships between totality of circumstances factors and understanding and appreciation of rights. Data were collected from 183 youths (140 boys) in pre- and postadjudication facilities in 2 states. Overall, youths demonstrated greater difficulty on measures of appreciation than understanding, with particular deficits in their abilities to comprehend the abstract concept of the right to silence. Results varied slightly by instrument, highlighting the importance of a multimodal assessment of these complex abilities. Examination of totality of circumstances factors identified relationships between some factors (e.g., age, verbal IQ, academic achievement) and Miranda comprehension, but revealed that other factors (e.g., gender, number of previous arrests) were not significantly related to Miranda understanding or appreciation. The findings support a nuanced conceptualization of Miranda rights comprehension that acknowledges the complexity of understanding and appreciating the warnings. Empirical analyses also support the continued use of some totality of circumstances factors and abandonment of others. Findings underscore the necessity of multimodal assessment and interpretation when conducting capacity to waive Miranda rights evaluations. (c) 2015 APA, all rights reserved).

    The charmed strange baryon Xi_c^0 was searched for in the decay channel Xi_c^0 -> Xi- pi+, and the beauty strange baryon Xi_b in the inclusive channel Xi_b -> Xi- l- anti-nu X, using the 3.5 million hadronic Z events collected by the DELPHI experiment in the years 1992--1995. The Xi- was reconstructed through the decay Xi- -> Lambda pi-, using a constrained fit method for cascade decays. An iterative discriminant analysis was used for the Xi_c^0 and Xi_b selection. The production rates were measured to be f_{Xi_c^0} x BR(Xi_c^0 -> Xi- pi+)= (4.7 +/- 1.4 (stat.) +/- 1.1 (syst.))10^{-4} per hadronic Z decay, and BR(b -> Xi_b) x BR(Xi_b -> Xi- l- X)= (3.0 +/- 1.0 (stat.) +/- 0.3 (syst.))10^{-4} for each lepton species (electron or muon). The lifetime of the Xi_b baryon was measured to be tau_{Xi_b} = 1.45{^{+0.55}_{-0.43}} (stat.) +/- 0.13 (syst.) ps. A combination with the previous DELPHI lifetime measurement gives tau_{Xi_b} = 1.48{^{+0.40}_{-0.31}} (stat.) +/- 0.12 (syst.) ps.

    XI Hong, a famous acupuncturist in the Southern Song Dynasty, has an important influence and status in history of Chinese acupuncture and moxibustion. After he moved to Linchuan, Jiangxi province, his descendants passed acupuncture from generation to generation. According to records, it was passed to 12 generations. After the tenth generation, it was also passed to apprentices besides descendants, such as accomplished acupuncturists CHEN Hong-gang, LIU Jin and others, forming XI Hong acupuncture school of thought. The poem of acupuncture and moxibustion XI Hong Fu is the representative work about XI Hong academic thought, which was additionally compiled or written by XI Hong's apprentices according to XI Hong academic thought. The poems are of characteristics in acupuncture application and association of acupoints. The academic thought and therapeutic methods of acupuncture in the poems still are widely used in modern clinical acupuncture practice.

  7. Late Holocene vegetation dynamics and lake geochemistry at Laguna Miranda, XI Region, Chile Dinámica vegetaciónal y geoquímica lacustre del Holoceno tardío en Laguna Miranda, XI Región, Chile

    Full Text Available Palynological and geochemical analysis of late Holocene lake sediments and dendrochronological analysis of Pilgerodendron in a volcanically active region of southern Chile reveal the long-term impact of a series of tephra fall events and tectonic activity on lake sedimentation and local vegetation. An upper 0,75 m core overlaps with a 4,35 m long Livingstone piston core to give a 4,60 m long sediment record, extending back to 4800 yr BP. Geochemical data shows the shift from allogenic dominance to authigenic and biogenic dominance as waterlogged soils developed within the catchment. This is presumed to have occurred under the influence of continued addition of nutrients to the catchment from tephra deposition and the associated high sedimentation rates. The palynological record from this site is dominated by Nothofagus dombeyi-type and Filicales. The most prominent changes in the pollen record, however, are the gradual decline in Podocarpus nubigena pollen throughout the last 4800 yr; the appearance and increase of Gramineae pollen during the past 2100 yr; and the rapid increase in the pollen of Pilgerodendron uviferum within the past 300-400 yr. Pilgerodendron tree-ring analysis and the pollen results over the last 400 years show that the most recent expansion of Pilgerodendron at the northern and eastern margins of this site is a response to either, periodic tectonic induced watertable changes, or is part of a long-term trend in gymnosperm growth around a shallowing lake margin. The decline of shade-intolerant trees such as Weinmannia and Podocarpus within a Nothofagus-rich forest community towards an increased presence of Pilgerodendron and Gramineae (likely Chusquea bamboo, that began over 2100 yr BP, may have been due as much to autogenic processes such as a change in the disturbance regime resulting in the development of waterlogged soils, rather than to an episode of climate change. It is important to recognise the potential effects of autogenic processes that may result from disturbance such as volcanic/tectonic activity in reconstructing past vegetation dynamics from pollen recordsAnálisis palinológicos y geoquímicos de sedimentos lacustres del holoceno tardío y análisis dendrocronológicos de Pilgerodendron uviferum en una zona volcánica activa del sur de Chile revelan el impacto a largo plazo de diversas caidas de tefra y actividad tectónica en la sedimentación lacustre y la vegetación de la zona. Una sección sedimentaria superior de 0,75 m traslapa una columna de pistón Livingstone de 4,35 m de largo para dar un registro de sedimentación de 4,60 m de longitud extendiéndose 4800 años AP. Datos geoquímicos muestran el cambio de dominancia alogénica a dominancia autígena y biogénica según se formaban los terrenos anegadizos dentro de la cuenca. Se presume que esto pudo producirse bajo la influencia de la llegada constante de nutrientes a la cuenca del lago procedentes del depósito de materias volcánicas conjuntamente con una alta sedimentación. El registro palinológico de este lugar está dominado por el tipo Nothofagus dombeyi y Filicales. Los cambios más notables que registra el polen son, no obstante, la declinación gradual del polen Podocarpus nubigena durante los últimos 4800 años; la aparición y aumento del polen Geamineae durante los pasados 2100 años; y el rápido aumento del polen Pilgerodendron uviferum en los últimos 300 a 400 años. El análisis de los anillos de leño de Pilgerodendron y los resultados que da el polen en los últimos 400 años muestran que la expansión más reciente de Pilgerodendron en las márgenes norte y este del lugar es una respuesta, bien a cambios periódicos de la capa freática por interacción tectónica, o es parte de un lento proceso de desarrollo de gimnospermas en las márgenes poco profundas del lago. La disminución de Weinmannia y Podocarpus, hace alrededor de 2100 años AP, se podría deber a procesos autogénicos resultando en el desarrollo de terrenos anegadizos, o a cambios en el régimen de perturbación, más bien que a un episodio de enfriamiento climático. En la reconstrucción de la dinámica de vegetaciones pasadas y partiendo de los registros del polen, es importante reconocer los efectos potenciales de los procesos autogénicos que pueden derivarse de perturbaciones tales como actividad volcánico/tectónica

  8. The role of suggestibility in determinations of Miranda abilities: a study of the Gudjonsson Suggestibility Scales.

    Traditionally, high levels of suggestibility have been widely assumed to be linked with diminished Miranda abilities, especially in relationship to the voluntariness of waivers. The current investigation examined suggestibility on the Gudjonsson Suggestibility Scales in a multisite study of pretrial defendants. One important finding was the inapplicability of British norms to American jurisdictions. Moreover, suggestibility appeared unrelated to Miranda comprehension, reasoning, and detainees' perceptions of police coercion. In testing rival hypotheses, defendants with high compliance had significantly lower Miranda comprehension and ability to reason about exercising Miranda rights than their counterparts with low compliance. Implications of these findings to forensic practice are examined.

  9. Fluid volcanism on Miranda and Ariel - Flow morphology and composition

    1991-01-01

    Several types of volcanic units have been recognized on the icy Uranian satellites Miranda and Ariel. On Miranda, ridges characterized by crest grooves are up to 10 km wide and 500 m high. A continuous flat-topped flow band also 10 km wide and 500 m high forms the outer southern margin of Elsinore Corona, which appears to comprise coalesced flow bands and ridges. On Ariel, in addition to at least one ridge unit similar to those on Miranda, flood plains material has covered the floors of deep chasmata (grabens) and an irregular depression. Flows on both satellites are characterized by linear vent geometries and distinct topographic margins, which indicate extrusion of a relatively viscous material. The topography of the flows can be used to estimate flow viscosity or yield strength using a Bingham plastic model. Extrusion viscosity estimates, incorporating plausible volcanologically based emplacement time scales and a rigid crust correction, range from 10 MP to 1 GP (10 TP in the unlikely absence of a chilled crust). Viscosity estimates are dependent on the assumed emplacement time scale, however, and could be as high as 10 PP, if a solid-state-based time scale is assumed.

    We report measurements of Xi and Xi-bar hyperon absolute yields as a function of rapidity in 158 GeV/c Pb+Pb collisions. At midrapidity, dN/dy = 2.29 +/- 0.12 for Xi, and 0.52 +/- 0.05 for Xi-bar, leading to the ratio of Xi-bar/Xi = 0.23 +/- 0.03. Inverse slope parameters fitted to the measured transverse mass spectra are of the order of 300 MeV near mid-rapidity. The estimated total yield of Xi particles in Pb+Pb central interactions amounts to 7.4 +/- 1.0 per collision. Comparison to Xi production in properly scaled p+p reactions at the same energy reveals a dramatic enhancement (about one order of magnitude) of Xi production in Pb+Pb central collisions over elementary hadron interactions.

  14. Miranda: cultura griega, estudios clásicos, relación con Andrés Bello

    2005-12-01

    Full Text Available Francisco de Miranda (1750-1816, precursor, herói e mártir da Independência da América Hispânica, estudou a língua grega e reuniu uma vasta biblioteca, com mais de 170 autores gregos. A idéia de liberdade para a américa espanhola surgiu nele em 1781, ligada a sua profunda admiração pela Grécia, na qual nasceu a liberdade. Aí está porque em sua longa viagem através da Europa, em 1786, apesar das ameaças e dos perigos, ele viajou para a Grécia, que gemia sob a dominação otomana. Ele desejava conhecer os lugares onde haviam nascido as idéias de liberdade e democracia, onde um pequeno povo havia vencido um gigantesco império absolutista. Miranda visitou o Pireu, Atenas, Corinto, Salamina, Maratona e depois Esmirna e Constantinopla. Escreveu um jornal muito interessante de sua viagem à Grécia. Em 1792, Miranda serviu na França, quando a Revolução Francesa ainda não tinha abandonado os ideais libertários. Lá, Miranda defendeu os princípios republicanos e a divisão dos poderes, invocando não Montesquieu, mas o exemplo da Grécia antiga. Pedro Grase iniciou com Miranda seu estudo da tradição humanista na América Latina e prossegue com Andrés Bello (1781-1816, o grande sábio que estudou a língua grega na biblioteca de Miranda, em Londres, e que se tornou latinista e helenista. Bello compartilha de sua convicção de que o estudo do latim e do grego e da cultura clássica está na base de toda a cultura sólida.

From this sample, the lifetime of the Xi0 hyperon was measured to be (3.065 +- 0.012(stat) +- 0.014(syst)) x 10^-10 s. This result is about two standard deviations above the world average and an order of magnitude more precise than the previous best measurement. With the same data sample, we have measured the ratio of anti-Xi0 and Xi0 fluxes in proton collisions at 400 GeV/c on a beryllium target.

    MIRANDA is a data preparation module of the AUS reactor neutronics scheme and is used to prepare multigroup cross-section data which are pertinent to a particular reactor system from a general purpose multigroup library of cross sections. The cross-section library has been prepared from ENDF/B and includes temperature dependent data and resonance cross sections represented by subgroup parameters. The MIRANDA module includes a multiregion resonance calculation in slab, cylinder or cluster geometry, a homogeneous Bsub(L) flux solution, and a group condensation facility. Interaction with other AUS modules, particularly for burnup calculations, is provided. (Author)

    In the year 2005 Laguna Verde power plant reaches 15 years of producing electric power in Mexico arriving to but of 100 million Megawatts-hour from their beginning of commercial activities. The Unit 1 that entered at July 29, 1990 and the Unit 2 at April 10, 1995, obtaining the Disposability Factors from their origin is: 84.63% in Unit 1 and 83.67% in Unit 2. The march of the X XI century gives big challenges of competition to the Laguna Verde Central, with the possible opening of the electric market to private investment, for their Goals and Objectives of a world class company, taking the evaluation system and qualification of the World Association of Nuclear Operators (WANO) that promotes the Excellence in the operation of the nuclear power stations in all their partners. This Association supports the development of programs that allow the monitoring of the behavior in Safety Culture, Human fulfilment, Equipment reliability, Industrial Safety, Planning, Programming and Control, Personalized Systematic Training, and the use of the Operational experience in the daily tasks. The present work tries to explain the system of evaluation/qualification of WANO, the definition of Goals and Objectives to reach the excellence and of the programs, it will present the Program of the Reliability of Equipment with its main actions the productivity.

  18. Dynamics of the Uranian and Saturnian satellite systems - a chaotic route to melting Miranda?

    International Nuclear Information System (INIS)

    Dermott, S.F.; Malhotra, R.B; Murray, C.D.

    1988-01-01

    Miranda's anomalously large inclination, in conjunction with the postaccretional resurfacing of both Miranda and Ariel and anomalously large eccentricities characterizing the inner Uranian satellites, are presently held to suggest the disruption of resonant configurations that once existed in this satellite system. Classical analytical methods for the dynamics of resonance are here used to demonstrate how temporary capture into a second- or higher-order resonance can generate large increases in eccentricity and inclination on comparatively short time-scales. Such capture into resonance may result in chaotic motion. 66 references

    In this report we present a music data harvesting system based on a plug-in for a popular music player. When a user is playing a song using the plug-in, information about the song is anonymously submitted to a server. The data gathered using MIRANDA is intended to be released to the MIR community....... We argue that even though content-based data is of interest to the community, also meta data and usage data can be important for research in music similarity....

  20. Examining the role of interrogative suggestibility in Miranda rights comprehension in adolescents.

    This study aimed to further clarify the association between interrogative suggestibility and Miranda rights comprehension in adolescents; in particular, we examined whether intellectual ability (IQ) serves as a mediator of this relationship. Participants completed Grisso's Miranda Instruments, the Wechsler Abbreviated Scale of Intelligence, and the Gudjonsson Suggestibility Scale. Many youth demonstrated poor comprehension of their rights, particularly younger and less intellectually capable adolescents. Both yield and shift components of interrogative suggestibility were inversely related to rights comprehension; however, IQ fully mediated these relationships. Neither demographic variables (gender, ethnicity, socio-economic status after controlling for IQ, and English as a second language (ESL) status) nor previous police experience were significantly associated with rights comprehension in the present sample. The implications of these findings are discussed.

    Full Text Available The water from the rivers Pigüeña and Somiedo is collected and conducted to the Salto de Miranda hydroelectric power station. The civil engineers Constructora Hidrocivil, S. A., carried out the project for the owners of this power station. Hidroeléctrica Cantábrica, S. A. The project is situated in the mountains, where a small dam collects the water. This is then led through a long conduit to the entry of the pressure pipes leading to the turbines. The water later flows back to the original river course. The total pressure head is 410 ms, and the mean volume of water which is exploited is 15 m3/sec. As the author is planning to publish additional articles describing specific aspects of the problem, no attempt is made here to emphasize the importance of many significant features of this project. In carrying out this project, the contractors devoted great care to the planning of the various constructional steps, in order that no delay in one particular operation should hold up the progress in the rest of the work.La entidad propietaria del Salto de Miranda es Hidroeléctrica del Cantábrico, S. A.; e Hidrocivil, S. A., participó muy activamente en la ejecución de los trabajos de obra e ingeniería civil. Fue una labor tan recia y tenaz de todos los que participaron en esta gran tarea, y tan elogioso su trabajo, su constante espíritu y voluntad de superación, que a ellos, obreros y técnicos, me debo sin reservas y con sinceridad. El éxito es suyo. Éxito basado en labor de equipo, perfecta compenetración de los binomios «hombre-hombres» «máquina-hombres». Quiero agradecer a la Compañía de Construcciones Hidráulicas y Civiles la oportunidad que me brindó de dirigir estos trabajos, que forjaron en mí una experiencia técnica y la satisfacción de una rendida colaboración. En otros números de esta revista espero poder extenderme, con mayor detalle, en otros aspectos específicos de esta importante obra.

  4. Start-up and operation of Laguna Verde-2

    Torres Ramirez, J.F.

    1996-01-01

    The 665 MWe Laguna Verde-2 nuclear generating unit was accepted into commercial operation on April 10, 1995. The boiling water reactor plant by General Electric (GE) was first synchronized with the grid on November 11, 1994. Laguna Verde-2 is identical with Laguna Verde-1 on the same site. That unit had gone critical for the first time in November 1988 and had first been synchronized with the power grid on April 13, 1989. Commercial operation of Laguna Verde-1 had been started on July 29, 1990. Mexico's only nuclear power plant had been built 70 km north of Veracruz on the east coast and had been scheduled to start operation in 1976. As the Mexican nuclear power program was reduced, the scheduled commissioning dates suffered more and more delays. In the full of 1987, the investigation by the Operational Safety Review Team (Osart) of the International Atomic Energy Agency (IAEA) had indicated that the safety requirements of installations and equpiment were met, and that the whole plant was well prepared for fueling. In mid-1988, the Mexican Government had issued the permit to fuel the Laguna Verde-1 reactor. The contract to build the two units had been awarded in 1972/73. No other nuclear power plants are currently under construction or in the planning phase in Mexico. (orig.) [de

    From samples of $pp$ collision data collected by the LHCb experiment at $\\sqrt{s}=7$, $8$ and $13$ TeV corresponding to integrated luminosities of 1.0, 2.0 and 1.5 fb$^{-1}$, respectively, a peak in both the $\\Lambda_b^0K^-$ and $\\Xi_b^0\\pi^-$ invariant mass spectra is observed. In the quark model, radially and orbitally excited $\\Xi_b^-$ resonances with quark content $bds$ are expected. Referring to this peak as $\\Xi_b(6227)^-$, the mass and natural width are measured to be $m_{\\Xi_{b}(6227)^-}=6226.9\\pm2.0\\pm0.3\\pm0.2$ MeV/$c^2$ and $\\Gamma_{\\Xi_b(6227)^-}=18.1\\pm5.4\\pm1.8$ MeV/$c^2$, where the first uncertainty is statistical, the second is systematic, and the third, on $m_{\\Xi_b(6227)^-}$, is due to the knowledge of the $\\Lambda_b^0$ baryon mass. Relative production rates of the ${\\Xi_b(6227)^-\\to\\Lambda_b^0K^-}$ and ${\\Xi_b(6227)^-\\to\\Xi_b^0\\pi^-}$ decays are also reported.

    Full Text Available Two aspects of Miranda Fricker’s book are criticised: the implicit assumption that ethical theory can solve fundamental problems in epistemology, and the excessive reliance on testimony as a fundamental source of knowledge. Against the former, it is argued that ethical theories are based on cultural prejudices to a higher extent than epistemological theories. Against the latter, argumentation is proposed as a more important epistemic practice than testimony.

    The decay asymmetries of the weak radiative Hyperon decays $\\Xi^{0}\\to \\Lambda \\gamma$ and $\\Xi^{0} \\to \\Sigma^{0}\\gamma$ have been measured with high precision using data of the NA48/1 experiment at CERN. From about 52000 $\\Xi^{0}\\to \\Lambda \\gamma$ and 15000 $\\Xi^{0} \\to \\Sigma^{0}\\gamma$ decays, we obtain for the decay asymmetries $\\alpha_{\\Xi^{0}\\to \\Lambda\\gamma}$ = -0.704 +- 0.019$_{stat}$ +- 0.064$_{syst}$ and $\\alpha_{\\Xi^{0}\\to \\Sigma^{0}\\gamma}$ = -0.729 +- 0.030$_{stat}$ +- 0.076$_{syst}$, respectively. These results are in good agreement with previous experiments, but more precise.

  9. Future perspectives in neutrino physics: The Laguna-LBNO case

    LAGUNA-LBNO is a Design Study funded by the European Commission to develop the de- sign of a deep underground neutrino observatory; its physics program involves the study of neutrino oscillations at long baselines, the investigation of the Grand Unication of elemen- tary forces and the detection of neutrinos from known and unknown astrophysical sources. Building on the successful format and on the ndings of the previous LAGUNA Design Study, LAGUNA-LBNO is more focused and is specically considering Long Baseline Neutrino Oscil- lations (LBNO) with neutrino beams from CERN. Two sites, Frejus (in France at 130 km) and Pyhasalmi (in Finland at 2300 km), are being considered. Three dierent detector technolo- gies are being studied: Water Cherenkov, Liquid Scintillator and Liquid Argon. Recently the LAGUNA-LBNO consortium has submitted an Expression of Interest for a very long baseline neutrino experiment, selecting as a rst priority the option of a Liquid Argon detector at Pyhasalmi.

    Full Text Available Este trabalho tem por objetivo apresentar a educação hebraica segundo o pensamento de Theobaldo Miranda Santos (1904-1971. Para tanto, investigaremos o capítulo do manual didático “Noções de História da Educação” que tratou exclusivamente desse tema. Buscamos problematizar o tratamento oferecido pelo intelectual ao tema da educação hebraica. Considerando que Theobaldo publicou seu manual didático pela primeira vez em 1945, no período de hegemonia de ideologias como o fascismo e o nazismo, procuramos compreender as nuances da educação hebraica de acordo com seu pensamento. Essas ideologias demonstravam grande preocupação com a chamada “questão judaica”, que já havia sido apontada por Karl Marx (1818-1883 ainda durante o século XIX, na Alemanha. O surgimento do antissemitismo no plano político foi uma característica desse período histórico. O tratamento oferecido por Theobaldo Miranda Santos ao tema da educação hebraica consiste no objeto dessa investigação.

    The “Miranda procedure” proposed for analyzing Dalitz plots for CP asymmetries in charged B and D decays in a model-independent manner is extended and refined in this paper. The complexity of Cabibbo-Kobayashi-Maskawa CP phenomenology through order λ6 is needed in searches for new dynamics (ND). Detailed analyses of three-body final states offer great advantages: (i) They give us more powerful tools for deciding whether an observed CP asymmetry represents the manifestation of ND and its features. (ii) Many advantages can already be obtained by the Miranda procedure without construction of a detailed Dalitz plot description. (iii) One studies CP asymmetries independent of production asymmetries. We illustrate the power of a second generation Miranda procedure with examples with time integrated rates for Bd/B¯d decays to final states KSπ+π- as trial runs, with comments on B±→K±π+π-/K±K+K-.

    Full Text Available Francisco de Miranda, en sus viajes por Europa, permanció casi tres meses en el Imperio Otomano (en Esmirna y Estambul. En sus escritos, el político venezolano se refirió especialmente a la vida social y cultural, a la economía y al ejército y a la defensa de Turquía. Por ello, el conocimiento de primera mano de estos aspectos parece la motivación fundamental de su estancia, sin que sea posible señalar ninguna gestión en busca de apoyo a la causa de la independencia americana.Francisco de Miranda, in his travels across Europe, visited for almost three months the Ottoman Empire (Izmir and Istambul. In his writings, the Venezuelan politician dealt especially with social and cultural life, the economy and the army and defence of the country. This is why the first-hand knowledge of these aspects seems to be the main reason of his stay; instead, it is not possible to find any step in the search of support for the American independence.

    Full Text Available Este no es un libro de historia del arte. Es un libro sobre como el arte se contextualiza en procesos históricos y los puede explicar, interpretar y dar sentido. Angélica Velázquez explora varias de las pinturas del artista mexicano decimonónico Primitivo Miranda para indagar por la visión que tenía aquel sobre el liberalismo. Miranda nació en Tula, hoy Estado de Hidalgo, en 1822. Desde temprano, dio muestras de algún talento artístico que comenzó a perfeccionar en Ciudad de México en la Academia de San Carlos. En 1841, y con el apoyo tanto de la Academia como de varios mecenas, viajo a Roma para continuar sus estudios, beneficio que recibieron en esos años varios de sus compañeros de la Academia. En la Ciudad Eterna estuvo bajo el tutelaje de los artistas Giovanni Silvagni y Francesco Coghetti. Por diversos motivos, Miranda no completo los seis años de estudios en Roma y regreso en 1848 a México.

    Full Text Available La Laguna Hule, localizada en la Vertiente Caribe, Costa Rica a 750m sobre el nivel del mar, forma parte del complejo de lagunas volcánicas llamado “Bosque Alegre”. El área de la laguna es de 60.3 ha y su profundidad máxima de 22.5m. La investigación se realizó de abril a setiembre de 1989 determinándose, en cada muestreo la temperatura, el óxido disuelto, el ácido sulfhídrico (H2S, el pH, la alcalinidad y la concentración de iones calcio, magnesio, hierro y manganeso. La laguna presenta un perfil clinógrado de oxígeno; el 60% del volumen total es anóxico con presencia de H2S a partir de los 8m de profundidad. Los valores de pH y alcalinidad indican que las aguas son bicarbonatadas, caracterizándose por un alto contenido de hierro. La curva de temperatura señala una diferencia de hasta 4.3 °C entre la superifcie y el fondo, permitiendo a la laguna permanecer estratificada (hay un epilimnion y un hipolimnion bien definido.

    Two structures are observed close to the kinematic threshold in the $\\Xi_b^0\\pi^-$ mass spectrum in a sample of proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb$^{-1}$ recorded by the LHCb experiment. In the quark model, two baryonic resonances with quark content $bds$ are expected in this mass region: the spin-parity $J^P = \\frac{1}{2}^+$ and $J^P=\\frac{3}{2}^+$ states, denoted $\\Xi_b^{\\prime -}$ and $\\Xi_b^{*-}$. Interpreting the structures as these resonances, we measure the mass differences and the width of the heavier state to be \\begin{eqnarray*} m(\\Xi_b^{\\prime -}) - m(\\Xi_b^0) - m(\\pi^{-}) &=& 3.653 \\pm 0.018 \\pm 0.006~{\\rm MeV}/c^2, \\\\ m(\\Xi_b^{*-}) - m(\\Xi_b^0) - m(\\pi^{-}) &=& 23.96 \\pm 0.12\\pm 0.06~{\\rm MeV}/c^2, \\\\ \\Gamma(\\Xi_b^{*-}) &=& 1.65 \\pm 0.31 \\pm 0.10~{\\rm MeV}, \\end{eqnarray*} where the first and second uncertainties are statistical and systematic, respectively. The width of the lighter state is consistent with zero, and we place ...

    Som præsident Xi Jinping har understreget – tydeligst i sin rapport til den 19. partikongres i oktober 2017 – er Kina trådt ind i en „ny æra”, hvor det er slut med den traditionelle „hold lav profil”-linje i kinesisk udenrigs- og sikkerhedspolitik. Kina vil nu tage stormagtsansvar og spille en...... „Den Nye Silkevej”, som initiativet er blevet døbt i danske medier, er uden tvivl det mest ambitiøse. Her er tale om præsident Xi Jinpings højest prioriterede strategiske satsning. Ikke kun i USA, men også i vesteuropæiske politiske cirkler er der en voksende skepsis at spore. „Den Nye Silkevej” anses...... grund: Hvis det lykkes for præsident Xi Jinping at anvende „Den Nye Silkevej” til at levere i forhold til de indenrigspolitiske behov og mål, så er det Kina, USA kommer til at stå over for, en anderledes og større udfordring....

    From samples of $pp$ collision data collected by the LHCb experiment at $\\sqrt{s}=7$, $8$ and $13$ TeV corresponding to integrated luminosities of 1.0, 2.0 and 1.5 fb$^{-1}$, respectively, a peak in both the $\\Lambda_b^0K^-$ and $\\Xi_b^0\\pi^-$ invariant mass spectra is observed. In the quark model, radially and orbitally excited $\\Xi_b^-$ resonances with quark content $bds$ are expected. Referring to this peak as $\\Xi_b(6227)^-$, the mass and natural width are measured to be $m_{\\Xi_{b}(6227)^-}=6226.9\\pm2.0\\pm0.3\\pm0.2$ MeV/$c^2$ and $\\Gamma_{\\Xi_b(6227)^-}=18.1\\pm5.4\\pm1.8$ MeV/$c^2$, where the first uncertainty is statistical, the second is systematic, and the third, on $m_{\\Xi_b(6227)^-}$, is due to the knowledge of the $\\Lambda_b^0$ baryon mass. Relative production rates of the ${\\Xi_b(6227)^-\\to\\Lambda_b^0K^-}$ and ${\\Xi_b(6227)^-\\to\\Xi_b^0\\pi^-}$ decays are also reported.

  18. Similar rates of protein adaptation in Drosophila miranda and D. melanogaster, two species with different current effective population sizes

    Full Text Available Abstract Background Adaptive protein evolution is common in several Drosophila species investigated. Some studies point to very weak selection operating on amino-acid mutations, with average selection intensities on the order of Nes ~ 5 in D. melanogaster and D. simulans. Species with lower effective population sizes should undergo less adaptation since they generate fewer mutations and selection is ineffective on a greater proportion of beneficial mutations. Results Here I study patterns of polymorphism and divergence at 91 X-linked loci in D. miranda, a species with a roughly 5-fold smaller effective population size than D. melanogaster. Surprisingly, I find a similar fraction of amino-acid mutations being driven to fixation by positive selection in D. miranda and D. melanogaster. Genes with higher rates of amino-acid evolution show lower levels of neutral diversity, a pattern predicted by recurrent adaptive protein evolution. I fit a hitchhiking model to patterns of polymorphism in D. miranda and D. melanogaster and estimate an order of magnitude higher selection coefficients for beneficial mutations in D. miranda. Conclusion This analysis suggests that effective population size may not be a major determinant in rates of protein adaptation. Instead, adaptation may not be mutation-limited, or the distribution of fitness effects for beneficial mutations might differ vastly between different species or populations. Alternative explanation such as biases in estimating the fraction of beneficial mutations or slightly deleterious mutation models are also discussed.

    2018-01-01

    The $\\Xi$ particles are baryons contains 2 constituent charm quarks in their structure which are expected to decay to high multi-body final states. The LHCb detector is ideally designed for studies of them due to its excellent particle identification and vertex reconstruction. Its capabilities in this area of physics was firmly demonstrated when LHCb announced the discovery of the first ever doubly charmed baryon, $\\Xi^{++}_{cc}$, in decays of $\\Xi^{++}_{cc} \\to \\Lambda^+K^-\\pi^+\\pi^+$ in 2017. This doubly charmed baryon was observed as a highly significant structure in the $\\Lambda^+_c K^-\\pi^+\\pi^+$ mass spectrum from proton-proton collision data recorded by the LHCb detector in Run2. A yield of 313 $\\pm$ 33 $\\Xi^{++}_{cc}$ candidates is measured and the local significances is in excess of 12 $\\sigma$ in the 13 TeV data. The properties of the peak suggest it is inconsistent with being a strongly decaying state. From the 13 TeV data, the mass is measured to be $3621.40\\pm 0.72(stat.) \\pm 0.27(syst....

    We perform a search for near-threshold $\\Xi_b^0$ resonances decaying to $\\Xi_b^- \\pi^+$ in a sample of proton-proton collision data corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by the LHCb experiment. We observe one resonant state, with the following properties: \\begin{eqnarray*} m(\\Xi_b^{*0}) - m(\\Xi_b^-) - m(\\pi^+) &=& 15.727 \\pm 0.068 \\, (\\mathrm{stat}) \\pm 0.023 \\, (\\mathrm{syst}) \\, \\mathrm{MeV}/c^2, \\\\ \\Gamma(\\Xi_b^{*0}) &=& 0.90 \\pm 0.16 \\, (\\mathrm{stat}) \\pm 0.08 \\, (\\mathrm{syst}) \\, \\mathrm{MeV} . \\end{eqnarray*} This confirms the previous observation by the CMS collaboration. The state is consistent with the $J^P=3/2^+$ $\\Xi_b^{*0}$ resonance expected in the quark model. This is the most precise determination of the mass and the first measurement of the natural width of this state. We have also measured the ratio \\begin{align*} \\frac{\\sigma(pp \\to \\Xi_b^{*0} X){\\cal{B}}( \\Xi_b^{*0} \\to \\Xi_b^- \\pi^+)}{\\sigma(pp \\to \\Xi_b^- X)} = 0.28 \\pm 0.03 \\, (\\mathrm{stat}...

    We present the first measurement of the atomic mass dependence of central $\\Xi^-$ and $\\overline{\\Xi}^+$ production. It is measured using a sample of 22,459 $\\Xi^-$'s and $\\overline{\\Xi}^+$'s produced in collisions between a 250 GeV/c $\\pi^-$ beam and targets of beryllium, aluminum, copper, and tungsten. The relative cross sections are fit to the two parameter function $\\sigma_0 A^{\\alpha}$, where A is the atomic mass. We measure $\\alpha$ = 0:924 $\\pm$ 0:020 $\\pm$ 0:025, for Feynman-x in the range $\\pm$ 0:09 < $x_F$ < 0:15.

    A report containing the activities carried out during the first reload of nuclear fuel and major maintenance in the Laguna Verde nuclear reactor is presented. The previous and the specific activities are included. These last are related without including the technical considerations, data or the operation details, because these data were documented inside the registrations of the CFE, the ININ and in personal way.

    We have searched in the decays of the GAMMA(1S), GAMMA(2S) and B mesons for the narrow state, xi, seen by the Mark III group in radiative psi decay. We find the product branching fractions B[GAMMA(1S) -> γxi] x B[xi -> K + K - ], B[GAMMA(2S) -> γxi] x B [xi -> K + K - ] and B[B -> xiX] x B[xi -> K + K - ] to be less than 2 x 10 -4 , 9 x 10 -5 and 3 x 10 -3 , respectively at 90% confidence level. These limits constrain theoretical models if the xi is interpreted as a Higgs boson. (orig.)

  11. Analysis of the socio political and environmental conflict about the use of La laguna park public spaces in Nueva Casarapa housing development; Miranda, Venezuela

    International Nuclear Information System (INIS)

    Zerpa, Mildred de

    2013-01-01

    Nueva Casarapa is an integral urban complex conceived under the concept of city. This complex has open spaces, shopping malls, green and public spaces, that are under the care of the owners, and a central natural park known as La Laguna. In 2009, starts a controversy that could become in a political environmental conflict with implications on the Municipio Plaza's government, because of the resolution of using the green areas of the park for a low price grocery market. This resolution was taken unilaterally by the Mayors' Office, not consulting the actors living in the complex. Besides the conflict for the use of this public space located inside of a private urban complex, there are discussions about which should be the institution to manage the resources obtained for the rent of the meeting spaces and who should be responsible of the maintenance staff. In function of this, it is possible to observe the rising of some conflicts between the different organizations and the users of the park that could lead to its damage.

  12. Estudo da Polarizacao dos Hiperons $\\Xi^-$ E $\\Omega^-$

    1995-01-01

    ln this thesis the polarization of the $\\Xi^-$ hyperon and the $\\Xi^+$ antihyperon produced in the Fermilab Experiment E791 was determined by the analysis of the weak decay $\\Xi^- \\to \\Lambda^0 + \\pi^-$. For $\\Xi^-$ produced in the interaction between a 500 GeV/c $\\pi^-$ beam and a unpolarized carbon (platinum) target in the region $p_t$ > 0.8 GeV/c and $X_F$ > 0, -10.9% ± 1.5% (-14.7% ± 3.1%) polarization was obtained perpendicular to the production plane and -5.92% ± 1.69% (-2.41%±3.53% $\\approx O$) polarization was measured for $\\Xi^+$. Evidence was also found for a polarized $\\Omega^-$ hyperon produced in the same experiment in the region $X_F$ >0, after analysis of the weak decay $\\Omega^- \\to \\Lambda^0 + K^-$.

    A search for baryon-number-violating $\\Xi_b^0$ oscillations is performed with a sample of $pp$ collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3 fb$^{-1}$. The baryon number at the moment of production is identified by requiring that the $\\Xi_b^0$ come from the decay of a resonance $\\Xi_b^{*-} \\to \\Xi_b^0 \\pi^-$ or $\\Xi_b^{\\prime-} \\to \\Xi_b^0 \\pi^-$, and the baryon number at the moment of decay is identified from the final state using the decays $\\Xi_b^0 \\to \\Xi_c^+ \\pi^-, ~ \\Xi_c^+ \\to p K^- \\pi^+$. No evidence of baryon number violation is found, and an upper limit is set on the oscillation rate of $\\omega < 0.08$ ps$^{-1}$, where $\\omega$ is the associated angular frequency.

    Highlights: • Neutronic/thermal hydraulic event in Laguna Verde is modeled. • A good agreement is obtained between SIMULATE-3K results and data plant for frequency and DR. • Other noise analysis techniques are used for the same purpose with good agreement. • Validation of SIMULATE-3K for stability analysis of Laguna Verde is confirmed - Abstract: Boiling Water Reactors are two phase flow systems which are susceptible to different types of flow instabilities. Among these are the coupled neutronic/thermal-hydraulic instabilities, these may compromise established fuel safety limits. These instabilities are characterized by periodic core-power and hydraulic oscillations. SIMULATE-3K code has been tested for stability analysis for several benchmarks, however to qualify the SIMULATE-3K code for a particular power plant a specific reactor plant analysis must be done. In this paper, the plant model of Laguna Verde Nuclear Power Plant is built and SIMULATE-3K is tested against the 1995 coupled neutronic/thermal-hydraulic instability event of Laguna Verde. Results obtained show the adequacy of this code to specific Laguna Verde power plant stability analysis.

    Full Text Available Se analiza la significación histórica de los diarios de viaje de Francisco de Miranda en los que se consigna su paso por el Sacro Imperio Romano Germánico. Tras posicionar brevemente a Miranda en la historiografía, se describe su ruta alemana del liberalismo temprano, que cobra relevancia para los estudios actuales de historia cultural y social. Se presta así atención a las experiencias de vida diaria, los procesos de transculturación y la transferencia de conocimientos entre múltiples centros/periferias. Estos viajes nutrieron decisivamente el concepto mirandino de “Colombeia” al servicio de la emancipación de la América española. Este enfoque de análisis es novedoso, ya que previamente Miranda solo ha sido tratado en la literatura, a lo sumo, bajo el sello de la biografía y el testimonio.

    Full Text Available Resumo. Este trabalho teve como objetivo analisar a influência da densidade arbórea e da borda sobre a quantidade e o volume nidal dos ninhos arborícolas de Nasutitermes sp., bem como, verificar a dependência do tamanho desses ninhos e a sua região de fixação em relação à arquitetura arbórea. A coleta de dados foi realizada em outubro de 2005, em um trecho da mata ribeirinha do rio Miranda no Pantanal Miranda-Abobral, sendo feita amostragem da quantidade e volume nidal dos ninhos arborícolas de Nasutitermes sp. e verificado a densidade de árvores de dossel através do método de amostragem por parcelas ao longo de um gradiente de profundidade na mata. Outros valores de arquitetura arbórea em que o ninho servia de abrigo também foram analisados, utilizando-se o coeficiente de correlação de Spearman, o teste de Kruskal-Wallis e o Qui-Quadrado. Dentre os resultados analisados, conclui-se que os ninhos arborícolas de Nasutitermes sp. não estão distribuídos ao acaso na mata. Mas sim, pode-se inferir que a quantidade e volume nidal, os locais de fixação, construção e desenvolvimento desses ninhos arborícolas na mata ribeirinha do rio Miranda sofrem interferência da estrutura arbórea da mata estudada.

    The Large Apparatus studying Grand Unification and Neutrino Astrophysics (LAGUNA) study [1] investigated seven pre-selected underground sites in Europe (Finland, France, Italy, Poland, Romania, Spain and UK), capable of housing large volume detectors for terrestrial, accelerator generated and astrophysical neutrino research. The study was focused on geo-technical assessment of the sites, concluding that no show-stoppers exist for the construction of the required large underground caverns in the chosen sites. The LAGUNA-LBNO FP7/EC-funded design study extends the LAGUNA study in two key aspects: the detailed engineering of detector construction and operation, and the study of a long-baseline neutrino beam from CERN, and possibly other accelerator centres in Europe. Based on the findings of the LAGUNA study, the Pyh¨asalmi mine in Finland is chosen as prime site for the far detector location. The mine offers the deepest underground location in Europe (-1400 m) and a baseline of 2’300 km from CERN (Fig. 1). ...

Measurement of the decay asymmetries of the radiative hyperon decays {xi}{sup 0}{yields}{lambda}{gamma} and {xi}{sup 0}{yields}{sigma}{sup 0}{gamma} with the NA48/1 experiment; Messung der Zerfallsasymmetrien der radiativen Hyperonzerfaelle {xi}{sup 0}{yields}{lambda}{gamma} und {xi}{sup 0}{yields}{sigma}{sup 0}{gamma} mit dem NA48/1-Experiment

    The radiative decay of a hyperon into a light hyperon and a photon allows to study the structure of the electroweak interaction of hadrons. For this purpose, the decay asymmetry is an appropriate observable. It describes the distribution of the daughter hyperon with respect to the polarization (vector)P of the mother hyperon by (dN)/(d cos({theta})){proportional_to}1+{alpha}vertical stroke (vector)P vertical stroke cos({theta}), where {theta} is the angle between (vector)P and the momentum of the daughter hyperon. The radiative decay {xi}{sup 0}{yields}{lambda}{sub {gamma}} is of particular interest since all calculations at quark level predict a positive decay asymmetry whereas two existing measurements result in a negative value of {alpha}{sub {xi}{sup 0}{yields}{lambda}{sub {gamma}}}=-0.73{+-}0.17. The goal of the analysis presented here was to verify these results and to improve the accuracy of the decay asymmetry measurement. In addition, the decay asymmetry of the similar decay {xi}{sup 0}{yields}{sigma}{sup 0}{sub {gamma}} was measured, and the well-known decay {xi}{sup 0}{yields}{lambda}{pi}{sup 0} was used to test the analysis strategy. During the data taking period in 2002, the NA48/1 experiment at CERN was searching for rare K{sub S} and hyperon decays. The collected data represents the world's largest sample of {xi}{sup 0} decays. From this sample, about 52,000 {xi}{sup 0}{yields}{lambda}{sub {gamma}} decays, 15,000 {xi}{sup 0}{yields}{sigma}{sup 0}{sub {gamma}} decays and 4 mill. {xi}{sup 0}{yields}{lambda}{pi}{sup 0} decays with small background were extracted as well as the corresponding anti {xi} decays. The available anti {xi} samples amount about one tenth of the {xi}{sup 0} samples. The measurement of the decay asymmetries was based on the comparison between data and a detailed Monte Carlo simulation, giving the following results: {alpha}{sub {xi}{sup 0}{yields}{lambda}{sub {gamma}}}=-0.701 {+-} 0.019{sub stat}{+-} 0.064{sub sys}, {alpha

  4. Laguna Verde: the nuclear debate in Mexico

    Weinberg, Bill.

    1987-01-01

    Mexico in planning to start up its first nuclear power station at Laguna Verde in the state of Veracruz (1988). The history of the plant is traced; it should have been finished by 1974. Both the fuel and the technology have been imported from the United States for Laguna Verde. The design, a Mark II Boiling Water Reactor, is controversial and there are doubts as to its safety. Opposition to the plant on safety and environmental grounds has grown. In April 1987 a 'Chernobyl anniversary' demonstration had 10,000 protesters and opponents of the plant are becoming more militant. The main opposition is from environmental and 'Green' groups but also includes intellectuals. However, politically, Mexico would find it embarrassing to cancel the plant and also it wants to be seen as a 'First World' rather than a 'Third World' country. (U.K.)

    A search for the doubly charmed baryon $\\Xi_{cc}^{+}$ in the decay mode $\\Xi_{cc}^{+} \\to \\Lambda_c^+ K^- \\pi^+$ is performed with a data sample, corresponding to an integrated luminosity of 0.65 fb$^{-1}$, of $pp$ collisions recorded at a centre-of-mass energy of 7 TeV. No significant signal is found in the mass range 3300--3800 MeV$/c^2$. Upper limits at the 95\\% confidence level on the ratio of the $\\Xi_{cc}^{+}$ production cross-section times branching fraction to that of the $\\Lambda_c^+$, $R$, are given as a function of the $\\Xi_{cc}^{+}$ mass and lifetime. The largest upper limits range from $R<1.5 \\times 10^{-2}$ for a lifetime of 100 fs to $R<3.9 \\times 10^{-4}$ for a lifetime of 400 fs.

    Using a proton-proton collision data sample corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 $\\Xi_b^0\\to\\Xi_c^+\\pi^-$, $\\Xi_c^+\\to pK^-\\pi^+$ signal decays are reconstructed. From this sample, the first measurement of the $\\Xi_b^0$ baryon lifetime is made, relative to that of the $\\Lambda_b^0$ baryon. The mass differences $M(\\Xi_b^0)-M(\\Lambda_b^0)$ and $M(\\Xi_c^+)-M(\\Lambda_c^+)$ are also measured with precision more than four times better than the current world averages. The resulting values are $\\frac{\\tau_{\\Xi_b^0}}{\\tau_{\\Lambda_b^0}} = 1.006\\pm0.018\\pm0.010$, $M(\\Xi_b^0) - M(\\Lambda_b^0) = 172.44\\pm0.39\\pm0.17 MeV/c^2$, $M(\\Xi_c^+) - M(\\Lambda_c^+) = 181.51\\pm0.14\\pm0.10 MeV/c^2$, where the first uncertainty is statistical and the second is systematic. The relative rate of $\\Xi_b^0$ to $\\Lambda_b^0$ baryon production is measured to be $\\frac{f_{\\Xi_b^0}}{f_{\\Lambda_b^0}}\\frac{{\\cal{B}}(\\Xi_b^0\\to\\Xi_c^+\\pi^-)}{{\\cal{B}}(\\Lam...

    The production of strange pentaquark states (e.g., Theta baryons and Xi /sup --/states) in hadronic interactions within a Gribov-Regge approach is explored. In this approach the Theta /sup +/(1540) and the Xi are produced by disintegration of remnants formed by the exchange of pomerons between the two protons. We predict the rapidity and transverse momentum distributions as well as the 4 pi multiplicity of the Theta /sup +/, Xi /sup --/ , Xi /sup -/, Xi /sup 0/ and Xi /sup +/ for square root s=17 GeV (SPS) and 200 GeV (RHIC). For both energies more than 10/sup -3/ Theta /sup +/ and more than 10 /sup -5/ Xi per pp event should be observed by the present experiments.

    2016-01-01

    In the present paper we obtain a necessary and sufficient condition to prove the Riemann hypothesis in terms of certain properties of local extrema of the function $\\Xi(t)=\\xi(\\tfrac{1}{2}+it)$. First, we prove that positivity of all local maxima and negativity of all local minima of $\\Xi(t)$ form a necessary condition for the Riemann hypothesis to be true. After showing that any extremum point of $\\Xi(t)$ is a saddle point of the function $\\Re\\{\\xi(s)\\}$, we prove that the above properties o...

    We report on measurements of the mass and lifetime of the $\\Xi_b^-$ baryon using about 1800 $\\Xi_b^-$ decays reconstructed in a proton-proton collision data set corresponding to an integrated luminosity of 3.0 fb$^{-1}$ collected by the LHCb experiment. The decays are reconstructed in the $\\Xi_b^-\\to\\Xi_c^0\\pi^-$, $\\Xi_c^0\\to pK^-K^-\\pi^+$ channel and the mass and lifetime are measured using the $\\Lambda_b^0\\to\\Lambda_c^+\\pi^-$ mode as a reference. We measure \\begin{equation} \\ M(\\Xi_b^-)-M(\\Lambda_b^0)=178.36\\pm0.46\\pm0.16~MeV/c^2, \\end{equation} \\begin{equation} \\frac{^\\tau\\Xi_b^-} {^\\tau\\Lambda_b^0}=1.089\\pm0.026\\pm0.011, \\end{equation} where the uncertainties are statistical and systematic, respectively. These results lead to a factor of two better precision on the $\\Xi_b^-$ mass and lifetime compared to previous best measurements, and are consistent with theoretical expectations.

    Full Text Available Neste artigo, analiso como brasileiras de classes média e média alta em Los Angeles lidam com o fenômeno da exotização das suas imagens. Observo que, embora originalmente articuladas a partir de Hollywood (Carmen Miranda nos limites da hierarquia entre as nações e do colonialismo, essas imagens são hoje alimentadas e recriadas também pelos próprios brasileiros. Uma das idéias centrais que defendo aqui é que embora tais imagens inicialmente restrinjam a ação das brasileiras, uma vez que sempre impõem o diálogo com os seus conteúdos, elas não o fazem permanentemente, ou seja, no processo de integração há espaço para a negociação de outras imagens e conteúdos e isto depende de fatores que vão além da exotização em si.This article discusses how middle and upper-middle class Brazilian women deal with their exoticized images in Los Angeles. It points out that although originally articulated from Hollywood (Carmen Miranda, within the limits of the hierarchy of nations and colonialism, today these images are also fed and recreated by Brazilians. One of the central ideas presented is that, despite constraining the movements and actions of the women, imposing on them the need to dialogue with their content, these exotic images do not do it permanently. In other words, in the process of integration, there is always room for negotiation of other images and contents that depend on factor other than exoticization itself.

    A sensitive search for the lepton-number-violating decay Xi(-)-->pmu(-)mu(-) has been performed using a sample of approximately 10(9) Xi(-) hyperons produced in 800 GeV/c p-Cu collisions. We obtain B(Xi(-)-->pmu(-)mu(-))<4.0x10(-8) at 90% confidence, improving on the best previous limit by 4 orders of magnitude.

    Full Text Available Estudiamos la abundancia y distribución estacional de las aves acuáticas en la laguna de Acuitlapilco, Tlaxcala, México. De febrero de 2011 a enero de 2012, realizamos censos en puntos de conteo para el registro de las especies. Registramos un total de 36 especies de aves acuáticas con una abundancia total acumulada de 48,794 individuos. Doce de las especies registradas fueron residentes, 10 migratorias y 14 fueron especies transitorias o de registro accidental. Observamos que la mayor riqueza de especies y abundancia de aves fueron en invierno, cuando la mayoría de las especies migratorias llegaron a la laguna. Nuestros resultados muestran que esta área es importante para especies de aves acuáticas tanto residentes como migratorias, y refleja la necesidad de un mayor número de estudios sobre el papel de las lagunas continentales como reservorios de biodiversidad.

    Laguna Verde is a BWR 5 containment Mark II. Designed by GE, two external re-circulation loops, each of them having two speed re-circulation pump and a flow control valve to define the drive flow and consequently the total core flow an power control by total core flow. Laguna Verde Design and operational experience has shown some insights to be considering in design for advanced BRW reactors in order to improve the potential of nuclear power plants. NSSS and Balance of plant design, codes used to perform nuclear core design, margins derived from engineering judgment, at the time Laguna Verde designed and constructed had conducted to have a plant with an operational license, generating with a very good performance and availability. Nevertheless, some design characteristics and operational experience have shown that potential improvements or areas of opportunity shall be focused in the advanced BWR design. Computer codes used to design the nuclear core have been evolved relatively fast. The computers are faster and powerful than those used during the design process, also instrumentation and control are becoming part of this amazing technical evolution in the industry. The Laguna Verde experience is the subject to share in this paper. (author)

    1981-05-01

    A block representative of a nuclear component has been welded containing intentional defects. Acoustic emission data taken during the welding correlate well with ultrasonic data. Repetitive ultrasonic examinations have been performed by skilled operators using a procedure based on that desribed in ASME Section XI. These examinations were performed by different examination teams using different ultrasonic equipment in such a manner that the effects on the repeatability of the ultrasonic test method caused by the operator and by the use of different equipment could be estimated. It was tentatively concluded that when considering a large number of inspections: (1) there is no significant difference in indication sizing between operators, and (2) there is a significant difference in amplitude and defect sizing when instruments having different, Code acceptable operating characteristics are used. It was determined that the Section XI sizing parameters follow a bivariate normal distribution. Data derived from ultrasonically and physically sizing indications in nuclear components during farication show that the Section XI technique tends to overestimate the size of the reflectors

    Four Zeeman spectrograms from Lick Observatory of xi Boo A and two of iota Peg at 2 A mm -1 have been measured to determine if a weak magnetic field is present in xi Boo A. The results indicate that the field is too weak to be measured by this technique on these spectrograms, although remeasurements of spectrograms from Mauna Kea at 3.4 A mm -1 still give a positive field of 170 gauss.

    Full Text Available ABSTRAK  Kehadiran sisa hutan bakau di laguna Bogowonto, pantai selatan Yogyakarta menunjukkan bahwa pada masa lalu laguna tersebut didominasi oleh hutan bakau, sehingga penelitian ini bertujuan mempelajari kehadiran vegetasi bakau di laguna-laguna dan muara sungai di pantai selatan tersebut. Ada empat laguna di pantai Selatan Yogyakarta, laguna Bogowonto, Serang, Progo, Opak, dan satu muara sungai, Kali Baron. Laguna tersebut merupakan laguna internitten, artinya pada musim kemarau, mulut sungainya tertutup gumuk pasir dan laguna didominasi oleh perairan tawar dan merupakan ekosistem tergenang. Sebaliknya di musim hujan mulut sungai terbuka, laguna bersifat sebagai ekosistem pasang surut. Data vegetasi dicuplik dengan menggunakan kuadrat plot berukuran 10m x 20m dengan ulangan dua kali. Kuadrat plot ditempatkan pada pusat distribusi mangrovenya, yang dipilih mulai dari rawa burit ke arah muara sungai. Tekstur tanah, hara tanah, salinitas air dan hara air juga dikaji. Kehadiran hutan bakau di laguna dibatasi oleh tekstur tanah. Tekstur pasir, 60-99 %, mendominasi laguna Serang, Progo, Opak dan muara kali Baron. Komunitas bakau hanya ditemukan di laguna Bogowonto, yang tersusun atas 5 jenis bakau, Sonneratia alba, Nypa fruticans, Acanthus ilicifolius, Acrosticum sp., dan Derris heterophylla, dan dua jenis spesies peralihan, Pandanus sp. dan Cynodon dactylon. Pola distribusi komunitasnya mengelompok (clump, mempunyai tipe riverine mangrove,dan tidak membentuk zonasi. Sonneratia hadir mulai dari muara sungai sampai di rawa burit. Ketika air surut salinitas berkisar antara 0-6,5 %. Nypa hanya ditemukan satu kelompok di kaki gumuk. Distribusi Sonneratia tidak ditentukan oleh tinggi genangan, akan tetapi tinggi pneumatophor mengikuti pola tinggi genangan air. Di laguna Bogowonto, spesies bakau tidak mempunyai zonasi dan beradaptasi pada sistem ekologinya.   ABSTRACT  The presence of mangrove remnant at the lagoon of Bogowonto River in the southern

    A search for narrow baryonic resonances decaying into Xi- pi- or Xi- pi+ and their antiparticles is carried out with the H1 detector using deep inelastic scattering events at HERA in the range of negative photon four-momentum transfer squared 2 < Q^2 < 100 GeV^2. No signal is observed for a new baryonic state in the mass range 1600 - 2300 MeV in either the doubly charged or the neutral decay channels. The known baryon Xi0 is observed through its decay mode into Xi- pi+. Upper limits are given on the ratio of the production rates of new baryonic states, such as the hypothetical pentaquark states Xi^{--}_{5q} or Xi^{0}_{5q}, relative to the Xi0 baryon state.

    Full Text Available O rio Miranda é um importante afluente do rio Paraguai e tem grande parte de seu curso na planície do Pantanal. O rio tem sinuosidade média a alta, sendo do tipo meandrante na maior parte do seu percurso em domínio aluvial. Com base nos padrões do canal e da planície, três segmentos fluviais com diferentes estilos foram caracterizados e descritos. Ainda nos domínios do planalto, o rio forma um cinturão de meandros numa planície agradacional, que está confinada em vale no embasamento cristalino. O rio deixa de correr num cinturão de meandros ao adentrar no Pantanal, para formar um cordão composto por canal e diques marginais que se destaca pela elevação mais alta em relação à planície agradacional, que se torna mais larga ao deixar o vale confinado. Paleocinturões de meandros e grandes meandros abandonados com dimensões superiores às dos canais atuais, existentes nas planícies agradacionais, permitem interpretar importantes mudanças ambientais e paleohidrológicas ocorridas a partir do Pleistoceno tardio. No seu baixo curso o rio volta a correr num cinturão de meandros, porem inciso em depósitos aluviais mais antigos, o que denuncia a natureza degradacional da planície distal do rio. Esta planície é palco da ação erosiva de fluxos de águas em lençol durante as inundações e de incisão por rede de pequenos canais tributários que drenam a planície depois das cheias. A avulsão ocorrida na altura do Morro do Azeite desempenhou importante papel na configuração do traçado do canal atual do rio Miranda, deslocando em 20 km para norte sua foz no rio Paraguai.  Palavras Chave – Rio Miranda, Pantanal, rio meandrante

    Full Text Available Dr. António Cupertino de Miranda Foundation is the owner of a toy automobile, trains and boats collection, mainly constituted of zinc alloy (zamac.The characteristics of the displayed materials used in the exhibition, essentially wood composites and carpeting, reads to foreseeing a certain vulnerability and consequent future alteration and decay of the existing collection. This work aimed to identify some of the pollutant materials and to characterize their emissions, to develop low cost monitoring methods easily performed by the museum staff members and to propose new solutions in order to delay a possible degradation of the collection, keeping the current exhibition conditions. Among the solutions proposed are the replacement of the existing MDF with MDF free from moisture or flame resistant treatments and the introduction of RB4 activated charcoal.

  15. Evolutionary traces decode molecular mechanism behind fast pace of myosin XI

    Full Text Available Abstract Background Cytoplasmic class XI myosins are the fastest processive motors known. This class functions in high-velocity cytoplasmic streaming in various plant cells from algae to angiosperms. The velocities at which they process are ten times faster than its closest class V homologues. Results To provide sequence determinants and structural rationale for the molecular mechanism of this fast pace myosin, we have compared the sequences from myosin class V and XI through Evolutionary Trace (ET analysis. The current study identifies class-specific residues of myosin XI spread over the actin binding site, ATP binding site and light chain binding neck region. Sequences for ET analysis were accumulated from six plant genomes, using literature based text search and sequence searches, followed by triple validation viz. CDD search, string-based searches and phylogenetic clustering. We have identified nine myosin XI genes in sorghum and seven in grape by sequence searches. Both the plants possess one gene product each belonging to myosin type VIII as well. During this process, we have re-defined the gene boundaries for three sorghum myosin XI genes using fgenesh program. Conclusion Molecular modelling and subsequent analysis of putative interactions involving these class-specific residues suggest a structural basis for the molecular mechanism behind high velocity of plant myosin XI. We propose a model of a more flexible switch I region that contributes to faster ADP release leading to high velocity movement of the algal myosin XI.

  16. Messung der Lebensdauer des $\\Xi^{0}$ -Hyperons mit dem NA48-Detektor

    One of the main characteristics of particles is the lifetime. The mean lifetime of the Xi0 hyperon, which can be determined theoretically from the Xi- lifetime by using the Delta I=1/2 rule, has been measured a couple of times. The most recent measurement from 1977 has a relative uncertainty of 5%, which could be improved by usind data from new experiments like NA48/1. The Xi0 lifetime is an important input parameter in the determination of the matrix element Vus of the Cabibbo-Kobayashi-Maskawa matrix in semileptonic Xi0 decays. In 2002 a high intensity data acquisition was performed by the NA48/1 collaboration, in which about 10^9 Xi0 decay candidates were recorded. From this sample 192000 events of the decay "Xi0 to Lambda pi0" were reconstructed and a subsample of 107000 could be used to determine the lifetime. The lifetime was determined by comparison of measured and simulated data in ten energy bins to avoid systematic effects. The result has a higher precision than older measurements. It differs from t...

  17. The Da Vinci Xi and robotic radical prostatectomy-an evolution in learning and technique.

    The da Vinci Xi robot has been introduced as the successor to the Si platform. The promise of the Xi is to open the door to new surgical procedures. For robotic-assisted radical prostatectomy (RARP)/pelvic surgery, the potential is better vision and longer instruments. How has the Xi impacted on operative and pathological parameters as indicators of surgical performance? This is a comparison of an initial series of 42 RARPs with the Xi system in 2015 with a series using the Si system immediately before Xi uptake in the same calendar year, and an Si series by the same surgeon synchronously as the Xi series using operative time, blood loss, and positive margins as surrogates of surgical performance. Subjectively and objectively, there is a learning curve to Xi uptake in longer operative times but no impact on T2 positive margins which are the most reflective single measure of RARP outcomes. Subjectively, the vision of the Xi is inferior to the Si system, and the integrated diathermy system and automated setup are quirky. All require experience to overcome. There is a learning curve to progress from the Si to Xi da Vinci surgical platforms, but this does not negatively impact the outcome.

    This article shows a non-lineal mathematical model for the condensate, and feed water systems and for feed water heater drains at the Laguna Verde Nuclear Power Station for its simulation in real time. The model allows the calculation of flows and pressures in all the piping system and equipment that integrate the systems. It was obtained by using the force unbalance in the fluid concept and is capable of reproducing its dynamic behavior through variations induced by the different operation modes and more common failures. The final model objective is to form part of the Laguna Verde simulator that will be used for operator training of this Nuclear Power Plant. [Espanol] En este articulo se muestra un modelo matematico no lineal de los sistemas de condensado, agua de alimentacion y drenes de calentadores de la central nuclear de Laguna Verde para su simulacion en tiempo real. El modelo permite calcular los flujos y las presiones en toda la red de tuberias y equipos que integran los sistemas. Se obtuvo utilizando el concepto de desbalance de fuerzas en el fluido, y es capaz de reproducir su comportamiento dinamico ante variaciones inducidas por los diversos modos de operacion y fallas mas comunes. El objetivo final del modelo es formar parte del simulador de Laguna Verde que se empleara para el adiestramiento de los operadores de dicha central nuclear.

    Using a $pp$ collision data sample corresponding to an integrated luminosity of 3.0~fb$^{-1}$, collected by the LHCb detector, we present the first search for the strangeness-changing weak decay $\\Xi_b^-\\to\\Lambda_b^0\\pi^-$. No $b$ hadron decay of this type has been seen before. A signal for this decay, corresponding to a significance of 3.2 standard deviations, is reported. The relative rate is measured to be ${{f_{\\Xi_b^-}}\\over{f_{\\Lambda_b^0}}}{\\cal{B}}(\\Xi_b^-\\to\\Lambda_b^0\\pi^-) = (5.7\\pm1.8^{+0.8}_{-0.9})\\times10^{-4}$, where $f_{\\Xi_b^-}$ and $f_{\\Lambda_b^0}$ are the $b\\to\\Xi_b^-$ and $b\\to\\Lambda_b^0$ fragmentation fractions, and ${\\cal{B}}(\\Xi_b^-\\to\\Lambda_b^0\\pi^-)$ is the branching fraction. Assuming $f_{\\Xi_b^-}/f_{\\Lambda_b^0}$ is bounded between 0.1 and 0.3, the branching fraction ${\\cal{B}}(\\Xi_b^-\\to\\Lambda_b^0\\pi^-)$ would lie in the range from $(0.57\\pm0.21)\\%$ to $(0.19\\pm0.07)\\%$.

    This study aims (1) to investigate the feasibility of robot-assisted penetrating keratoplasty (PK) using the new Da Vinci Xi Surgical System and (2) to report what we believe to be the first use of this system in experimental eye surgery. Robot-assisted PK procedures were performed on human corneal transplants using the Da Vinci Xi Surgical System. After an 8-mm corneal trephination, four interrupted sutures and one 10.0 monofilament running suture were made. For each procedure, duration and successful completion of the surgery as well as any unexpected events were assessed. The depth of the corneal sutures was checked postoperatively using spectral-domain optical coherence tomography (SD-OCT). Robot-assisted PK was successfully performed on 12 corneas. The Da Vinci Xi Surgical System provided the necessary dexterity to perform the different steps of surgery. The mean duration of the procedures was 43.4 ± 8.9 minutes (range: 28.5-61.1 minutes). There were no unexpected intraoperative events. SD-OCT confirmed that the sutures were placed at the appropriate depth. We confirm the feasibility of robot-assisted PK with the new Da Vinci Surgical System and report the first use of the Xi model in experimental eye surgery. Operative time of robot-assisted PK surgery is now close to that of conventional manual surgery due to both improvement of the optical system and the presence of microsurgical instruments. Experimentations will allow the advantages of robot-assisted microsurgery to be identified while underlining the improvements and innovations necessary for clinical use.

    The Level 1 results of Laguna Verde Nuclear Power Plant PRA are presented in the I nternal Event Analysis of Laguna Verde Unit 1 Nuclear Power Plant , CNSNS-TR-004, in five volumes. The reports are organized as follows: CNSNS-TR-004 Volume 1: Introduction and Methodology. CNSNS-TR-004 Volume 2: Initiating Event and Accident Sequences. CNSNS-TR-004 Volume 3: System Analysis. CNSNS-TR-004 Volume 4: Accident Sequence Quantification and Results. CNSNS-TR-004 Volume 5: Appendices A, B and C. This volume presents the results of the system analysis for the Laguna Verde Unit 1 Nuclear Power Plant. The system analysis involved the development of logical models for all the systems included in the accident sequence event tree headings, and for all the support systems required to operate the front line systems. For the Internal Event analysis for Laguna Verde, 16 front line systems and 5 support systems were included. Detailed fault trees were developed for most of the important systems. Simplified fault trees focusing on major faults were constructed for those systems that can be adequately represent,ed using this kind of modeling. For those systems where fault tree models were not constructed, actual data were used to represent the dominant failures of the systems. The main failures included in the fault trees are hardware failures, test and maintenance unavailabilities, common cause failures, and human errors. The SETS and TEMAC codes were used to perform the qualitative and quantitative fault tree analyses. (Author)

    In 2010 the nuclear power plant of Laguna Verde will implement the extended power upbeat in both units of the plant. Agree with methodology of NEDC-33004P-A, (constant pressure power up rate), and the source term of core, for accidents evaluations, were increased in proportion to the ratio of power level. This means that for the case of a design basis accident of loss of coolant an increase of power of 15% originated an increase of 15% in dose to main control room. Using the method of NEDC-33004P-A to extended power upbeat conditions was determined that the dose value to main control room is very near to regulatory limit established by SRP 6.4. By the above and in order to recover the margin, the nuclear power plant of Laguna Verde will calculate an alternative source term following the criteria established in RG 1.183 (alternative radiological source term for evaluating DBA at nuclear power reactor). This approach also have a more realistic dose value using the criterion of 10-CFR-50.67, in addition is predicted to get the benefit of additional operational flexibilities. This paper present the proposal of implementing the alternative source term in Laguna Verde. (Author)

    In 2002 a high intensity data acquisition for K_S mesons and neutral hyperons was performed by the NA48/1 experiment, in which about 10^9 Xi^0 decay candidates were recorded. Within this work 6657 Xi^0 -> Sigma^+ e^- anti-nu and 581 anti-Xi^0 -> anti-Sigma^+ e^+ nu events were selected from that data sample and the branching ratios BR1(Gamma(Xi^0 -> Sigma^+ e^- anti-nu)/Gamma(Xi^0 total))=( 2.533 +-0.032(stat) -0.076+0.089(syst) )10^-4 and BR2(Gamma(anti-Xi^0 -> anti-Sigma^+ e^+ nu)/Gamma(Anti-Xi^0 total))= ( 2.57 +-0.12(stat) -0.09+0.10(syst) )10^-4 were determined. The result for BR1 is 3.5 times more precise than the previously published measurement. The analysis of anti-Xi^0-beta decays is the first measurement of BR2. Both results agree with the theoretical prediction of 2.6*10^-4. From BR1, the CKM matrix element |Vus| = 0.209 +- 0.004(exp) +- 0.026(syst) was determined by using the experimental value for the form factor ratio g1/f1. The dominant uncertainty is given by the error on g1/f1. Besides, 99 X...

    One of the biggest difficulties in obtaining an analytical expression for the J({xi}, {beta}) function is its explicit dependence on the Doppler broadening function {psi}(x,{xi}). The objective of this paper is to present a method for the fast and accurate calculation for the J({xi}, {beta}) function based on the recent advances in the calculation of the Doppler broadening function and on a systematic analysis of its integrand. The methodology proposed uses an analytical formulation for the calculation of {psi}(x, {xi}) and a representation in series for error functions with complex argument. The results were satisfactory from the accuracy and processing time standpoint and are an option to other calculation methods found in the literature.

    Since the Tokai criticality accident in 1999, there has been no specialized manufacturer conducting uranium re-conversion in Japan. For this reason, Nuclear Fuel Industries, Ltd. (NFI) imports from overseas almost all the uranium oxide powder used for manufacturing pellets for nuclear fuel assemblies. To date, an NT-IX package has been used for transporting the uranium oxide powder. However, due to the adoption of IAEA TS-R-1 into Japanese domestic regulations, we have begun to use a new TNF-XI powder package because the NT-IX package can suffer major deformation under the drop test III condition. The TNF-XI package was jointly developed by COGEMA LOGISTICS of France and NFI from 2000, and started to be used for actual transportation in 2003. This package has improved transport efficiency, handling operability and safety performance in comparison to its predecessor. This paper describes the characteristics of the new TNF-XI package and its actual transportation records and performance

    We have studied the turnover and accumulation of rabbit factor XI (F.XI) in atherosclerotic lesion in Watanabe-hereditable hyperlipidemic rabbit (WHHL rabbit) to reveal the participation of blood coagulation in atherosclerotic lesion. Rabbit F.XI was iodinated and administered intravenously to WHHL rabbits and Japanese white rabbits. The turnover of 125 I-rabbit F.XI was significantly faster in WHHL rabbits (T1/2 = 2.84 +/- 0.44 days) than in normal rabbits (T1/2 = 4.44 +/- 0.42 days). The thoracic aorta of WHHL rabbit was strongly labelled with 125 I-rabbit F.XI, in sections obtained after 5 days by en-face autoradiography, whereas no radioactivity was detected in normal aorta. By an immunohistochemical study of WHHL rabbit aorta, we confirmed that many F.XI- and fibrin-related compounds existed in the atheroma, whereas albumin did not in these area. These results suggest that the activation of F.XI proceeds on the atherosclerotic lesions of WHHL rabbits

  19. Section XI -- 25 years of development

    International Nuclear Information System (INIS)

    Hedden, O.F.

    1996-01-01

    The original concept of nuclear power plant designers was that the higher standards of design and fabrication would make inservice inspections unnecessary, and little attention was given to provisions for access. By 1966 the Atomic Energy Commission recognized that a planned program of periodic inservice inspections would be needed. They began development of criteria, and encouraged industry code-writing organizations to do likewise. These groups joined forces in 1968, and their product was published by ASME in 1970 as part of the Boiler and Pressure Code, Section XI, Rules for Inservice Inspection of Nuclear Reactor Coolant Systems. Section XI, 24 pages in 1970, is now 723 pages. While it originally covered only light water reactor Class 1 components and piping, it now includes Class 2, 3, and containment, and liquid metal cooled reactor plants. Along the way, rules have been developed for gas-cooled and low pressure heavy water reactor plants. The growth in size of Section XI from its modest beginning has been largely because of recognition that the rules governing plant inspection/operation need to be considerably different from the rules provided for the component designer/manufacturer. Rules have been developed in the areas of repair/replacement technology, NDE methodology, NDE acceptance standards, and analytical evaluation methods in the absence of appropriate rules in Section III

    2010-01-01

    Within the LAGUNA design study, seven candidate sites are being assessed for their feasibility to host a next-generation, very large neutrino observatory. Such a detector will be expected to feature within a future European accelerator neutrino programme (Superbeam or Beta Beam), and hence the distance from CERN is of critical importance. In this article, the focus is a $^{18}$Ne and $^{6}$He Beta Beam sourced at CERN and directed towards a 50 kton Liquid Argon detector located at the LAGUNA sites: Slanic (L=1570 km) and Pyh\\"{a}salmi (L=2300 km). To improve sensitivity to the neutrino mass ordering, these baselines are then combined with a concurrent run with the same flux directed towards a large Water \\v{C}erenkov detector located at Canfranc (L=650 km). This degeneracy breaking combination is shown to provide comparable physics reach to the conservative Magic Baseline Beta Beam proposals. For $^{18}$Ne ions boosted to $\\gamma=570$ and $^{6}$He ions boosted to $\\gamma=350$, the correct mass ordering can be...

    By means of the use of the performance evaluation of power system efficiencies (PEPSE) code was modeled the vapor cycle of the nuclear power station of Laguna Verde to reproduce the nuclear plant behavior to conditions of thermal power, licensed at present (2027 MWt); with the purpose of having a base line before the implementation of the project of extended power increase. The model of the gauged vapor cycle to reproduce the nuclear plant conditions makes use of the PEPSE model, design case of the vapor cycle of nuclear power station of Laguna Verde, which has as main components of the model the great equipment of the vapor cycle of Laguna Verde. The design case model makes use of information about the design requirements of each equipment for theoretically calculating the electric power of exit, besides thermodynamic conditions of the vapor cycle in different points. Starting from the design model and making use of data of the vapor cycle measured in the nuclear plant; the adjustment factors were calculated for the different equipment s of the vapor cycle, to reproduce with the PEPSE model the real vapor cycle of Laguna Verde. Once characterized the model of the vapor cycle of Laguna Verde, we can realize different sensibility studies to determine the effects macros to the vapor cycle by the variation of certain key parameters.

    Laguna Salada in northern Baja California, Mexico, is an active half-graben product of the trans-tensional tectonics of the Gulf of California. It is sensitive to changes in sediment supply from the Colorado River basin. We present a time series analysis of the upper 980 m of a gamma-ray log from a borehole drilled near the Laguna Salada fault. The power spectrum of the gammaray log resembles the spectrum of {delta}{sup 1}8{omicron} Pleistocene isotopic variations from ice cores and from the deep ocean, known to be strongly controlled by Milankovitch cycles. We correlate {delta}{sup 1}8{omicron} stages with silty and sandy intervals in the log. Downcore ages for the last 780 ky are constrained within {approx}10 kyr. We derive a simple time vs. depth calibration relation for the basin over this time interval. Estimated sedimentation rates at the drill site appear to be constant with a value of {approx}1.6 mm/yr. We propose that this subsidence rate is produced by the Laguna Salada fault. [Spanish] La cuenca de Laguna Salada en el norte de Baja California, Mexico, es un semigraben activo producto de la tectonica ranstensional del Golfo de California. Esta cuenca endorreica es sensible a cambios en sedimentacion por variaciones en el aporte e sedimentos de fuentes cercanas y distales transportados por arroyos de las sierras adyacentes y por el Rio Colorado. Esta cuenca es un sitio excepcional para explorar el uso de cambios climaticos ciclicos como herramienta de datacion y estimar tasas de sedimentacion y subsidencia en el area. Para demostrar esto se presenta un analisis de series de tiempo de un registro de rayos de gama de un pozo geotermico exploratorio perforado adyacente a la falla de Laguna Salada, la cual limita el margen oriental de la cuenca. Los resultados del analisis indican que el espectro de los primeros 980 m del registro de rayos gama tiene una alta coherencia con el espectro de registros isotopicos paleoclimaticos de {delta}{sup 1}8{omicron} del

    Safety is one of the main factors in the construction and operation of a modern nuclear power plant. There are many barriers between the fission products produced in the fuel elements of the core, and the environment: the cladding of the fuel pins which are enclosed in the reactor core, the pressure vessel containing the core and which in turn is enclosed in the reactor containment, all this being located in a low-pressure secondary containment or reactor building. Despite these precautions, nuclear safety is still a widely-discussed issue. The important fact remains, however, that there has not been a single radiation-induced fatality or serious injury at any civilian nuclear power plant during 20 years of nuclear power generation. This includes the accident that occurred in March 1979 at the Three Mile Island nuclear plant in the USA. A substantial component contributing to safety in a nuclear power plant is the containment. The following photos of Laguna Verde, Mexico's first nuclear power station being constructed at Alta Lucero in Vera Cruz, give an impression of how strong this concrete and steel containment actually is. Laguna Verde consists of two 600 MWe units and the plant is scheduled for commercial operation in 1982. Construction began in 1974. Both units are boiling-water reactors. The photos show, in general, the construction of the primary containment for the reactors (the dry wells). The dry well contains the reactor itself and has two layers: the leak-tight steel liner and the heavy concrete building. The purpose of the primary containment is to retain steam and gases that might escape in an emergency and to direct these through relief tubes to a water pond for cooling. Surrounding this primary containment will be a reactor building which serves as a secondary low-pressure containment, able to operate at pressures up to 0.2 atmospheres.

    Full Text Available Laguna de Cuyutlán, in the state of Colima, Mexico, is the only large coastal wetland in a span of roughly 1150 km. Despite this, the study of its birds has been largely neglected. Between 2003 and 2006 we assessed the waterbirds nesting in the middle portion of Laguna Cuyutlán, a large tropical coastal lagoon, through field visits. We documented the nesting of 15 species of non-Laridae waterbirds: Neotropic Cormorant (Phalacrocorax brasilianus, Tricolored Egret (Egretta tricolor, Snowy Egret (Egretta thula, Little Blue Heron (Egretta caerulea, Great Egret (Ardea alba, Cattle Egret (Bubulcus ibis, Black-crowned Nightheron (Nycticorax nycticorax, Yellow-crowned Night-heron (Nyctanassa violacea, Green Heron (Butorides virescens, Roseate Spoonbill (Platalea ajaja, White Ibis (Eudocimus albus, Black-bellied Whistling-duck (Dendrocygna autumnalis, Clapper Rail (Rallus longirostris, Snowy Plover (Charadrius alexandrinus, and Black-necked Stilt (Himantopus mexicanus. These add to six species of Laridae known to nest in that area: Laughing Gulls (Larus atricilla, Royal Terns (Thalasseus maximus, Gull-billed Terns (Gelochelidon nilotica, Forster’s Terns (S. forsteri, Least Terns (Sternula antillarum, and Black Skimmer (Rynchops niger, and to at least 57 species using it during the non-breeding season. With such bird assemblages, Laguna Cuyutlán is an important site for waterbirds, which should be given conservation status. Rev. Biol. Trop. 56 (1: 391-397.

    To increase the spent fuel storage capacity at the Laguna Verde Station in a safe and economical manner and assure a continuous operation of the first Mexican Nuclear Plant, Comision Federal de Electricidad (CFE), the Nation's Utility, seeked alternatives considering the overall world situation, the safety and licensing aspects, as well as the economics and the extent of the nuclear program of Mexico. This paper describes the alternatives considered, their evaluation and how the decision taken by CFE in this field, provides the Laguna Verde Station with a maximum of 37 years storage capacity plus full core reserve

  9. Accelerated pseudogenization on the neo-X chromosome in Drosophila miranda

    Y chromosomes often degenerate via the accumulation of pseudogenes and transposable elements. By contrast, little is known about X-chromosome degeneration. Here we compare the pseudogenization process between genes on the neo-sex chromosomes in Drosophila miranda and their autosomal orthologues in closely related species. The pseudogenization rate on the neo-X is much lower than the rate on the neo-Y, but appears to be higher than the rate on the orthologous autosome in D. pseudoobscura. Genes under less functional constraint and/or genes with male-biased expression tend to become pseudogenes on the neo-X, indicating the accumulation of slightly deleterious mutations and the feminization of the neo-X. We also find a weak trend that the genes with female-benefit/male-detriment effects identified in D. melanogaster are pseudogenized on the neo-X, implying the masculinization of the neo-X. These observations suggest that both X and Y chromosomes can degenerate due to a complex suite of evolutionary forces.

    Laguna Potrok Aike, a maar lake in southern-most Patagonia, is located at about 110 m a.s.l. in the Pliocene to late Quaternary Pali Aike Volcanic Field (Santa Cruz, southern Patagonia, Argentina) at about 52°S and 70°W, some 20 km north of the Strait of Magellan and approximately 90 km west of the city of Rio Gallegos. The lake is almost circular and bowl-shaped with a 100 m deep, flat plain in its central part and an approximate diameter of 3.5 km. Steep slopes separate the central plain from the lake shoulder at about 35 m water depth. At present, strong winds permanently mix the entire water column. The closed lake basin contains a sub saline water body and has only episodic inflows with the most important episodic tributary situated on the western shore. Discharge is restricted to major snowmelt events. Laguna Potrok Aike is presently located at the boundary between the Southern Hemispheric Westerlies and the Antarctic Polar Front. The sedimentary regime is thus influenced by climatic and hydrologic conditions related to the Antarctic Circumpolar Current, the Southern Hemispheric Westerlies and sporadic outbreaks of Antarctic polar air masses. Previous studies demonstrated that closed lakes in southern South America are sensitive to variations in the evaporation/precipitation ratio and have experienced drastic lake level changes in the past causing for example the desiccation of the 75 m deep Lago Cardiel during the Late Glacial. Multiproxy environmental reconstruction of the last 16 ka documents that Laguna Potrok Aike is highly sensitive to climate change. Based on an Ar/Ar age determination, the phreatomagmatic tephra that is assumed to relate to the Potrok Aike maar eruption was formed around 770 ka. Thus Laguna Potrok Aike sediments contain almost 0.8 million years of climate history spanning several past glacial-interglacial cycles making it a unique archive for non-tropical and non-polar regions of the Southern Hemisphere. In particular, variations of

  12. Ultrabass Sounds of the Giant Star xi Hya

    2002-05-01

    First Observations of Solar-type Oscillations in a Star Very Different from the Sun Summary About 30 years ago, astronomers realised that the Sun resonates like a giant musical instrument with well-defined periods (frequencies). It forms a sort of large, spherical organ pipe. The energy that excites these sound waves comes from the turbulent region just below the Sun's visible surface. Observations of the solar sound waves (known as " helioseismology ") have resulted in enormous progress in the exploration of the interior of the Sun, otherwise hidden from view. As is the case on Earth, seismic techniques can be applied and the detailed interpretation of the observed oscillation periods has provided quite accurate information about the structure and motions inside the Sun, our central star. It has now also become possible to apply this technique to some solar-type stars. The first observations concerned the northern star eta Bootis (cf. ESO PR 16/94 ). Last year, extensive and much more accurate observations with the 1.2-m Swiss telescope at the ESO La Silla Observatory proved that Alpha Centauri , a solar "twin", behaves very much like the Sun (cf. ESO PR 15/01 ), and that some of the periods are quite similar to those in the Sun. These new observational data were of a superb quality, and that study marked a true break-through in the new research field of " asteroseismology " (seismology of the stars) for solar-type stars. But what about other types of stars, for instance those that are much larger than the Sun? Based on an extremely intensive observing project with the same telescope, an international group of astronomers [1] has found that the giant star xi Hya ("xi" is the small greek letter [2]; "Hya" is an abbreviation of "Hydrae") behaves like a giant sub-ultra-bass instrument . This star is located in the constellation Hydra (the Water-Monster) at a distance of 130 light-years, it has a radius about 10 times that of the Sun and its luminosity is about 60

    Full Text Available Las lagunas de Pom y Atasta forman parte del área natural protegida de flora y fauna laguna de Términos en la región de Campeche, México. Esta es una  importante área ecológica ya que es el habitad de muchas especies nativas y migratorias. Estas lagunas han sido afectadas por actividades industriales y por descargas de aguas residuales. Monitoreo de nitrógeno, fósforo y coliformes fecales en agua superficial fueron realizados a lo largo de ambas lagunas durante las temporadas de seca, lluvia y nortes durante un año. Las altas temperaturas en verano (31 ºC y mínimas en nortes (25ºC fueron asociadas con valores de oxigeno disuelto (5.1 y 6.3 mg l-1, respectivamente indicando también una probable relación con la actividad fitoplanctonica. El pH (8.0-8.2 y la salinidad (0.32 - 3.48 UPS no mostraron variación significativa entre las tres temporadas climáticas. El nivel de amonio no fue mayor a los valores sugeridos para el control de eutroficación (0.1 mg l-1, mientras que los niveles de fósforo fueron de mayor concentración (2.0-3.5 mg l-1 que aquellos considerados seguros (0.01-0.125 mg l-1 para el medio ambiente. Las más altas concentraciones de N y P cerca de las áreas habitadas sugiere un importante contribución de nutrientes provenientes de aguas de desecho, asociado con la descomposición de material orgánico. La concentración de coliformes fecales durante la temporada de lluvias y nortes (8.0-26.0 MPN 100 ml-1 fue mayor que durante la temporada de seca (1.3-3.5 MPN 100 ml-1 sugiriendo un importante acceso por escurrimiento pluvial y aguas residuales no tratadas proveniente de las áreas cercanas al lago habitadas. La deforestación de manglares y la descontrolada actividad de agricultura afectaran la calidad del agua en ambos lagos en el futuro.

    A study of inclusive Xi /sup -/ production from a high statistics K /sup -/p experiment at 4.2 GeV/c has been made. The total Xi /sup -/ production cross section is 157+or-8 mu b. Approximately 15% of the Xi /sup -/ arise from decay of the Xi */sup Q/(1530) resonance. The polarization of Xi /sup -/ is found to be negative and is nearly equal in value to that of the Lambda /sup 0/ from the inclusive reaction K /sup -/+p to Lambda /sup 0/+anything. An analysis of the inclusive production of Xi /sup -/ has been made in the framework of the triple- Regge formalism. (15 refs).

    2005-01-01

    Since 1996 Section XI of the ASME Boiler and Pressure Vessel Code has actively incorporated risk-informed concepts. The risk-informed process provides a framework for allocating inspection resources in a cost-effective manner and helps focus inspections where most critical for plant safety. Based on the success of the risk-informed ISI piping applications at US and non-US plants, Section XI has refined existing Code Cases and expanded the use of the risk-informed process to a variety of high-risk components and systems. The risk informed approach started in the area of inspection and is now being expanded to other plant maintenance activities. This article summarizes the Section XI actions and the continued development of the risk-informed process to improve nuclear plant maintenance. (author)

  18. Implementacion de modulos constructivistas que atiendan "misconceptions" y lagunas conceptuales en temas de la fisica en estudiantes universitarios

    Santacruz Sarmiento, Neida M.

    Este estudio se enfoco en los "misconception" y lagunas conceptuales en temas fundamentales de Fisica como son Equilibrio Termodinamico y Estatica de fluidos. En primer lugar se trabajo con la identificacion de "misconceptions" y lagunas conceptuales y se analizo en detalle la forma en que los estudiantes construyen sus propias teorias de fenomenos relacionados con los temas. Debido a la complejidad en la que los estudiantes asimilan los conceptos fisicos, se utilizo el metodo de investigacion mixto de tipo secuencial explicativo en dos etapas, una cuantitativa y otra cualitativa. La primera etapa comprendio cuatro fases: (1) Aplicacion de una prueba diagnostica para identificar el conocimiento previo y lagunas conceptuales. (2) Identificacion de "misconceptions" y lagunas del concepto a partir del conocimiento previo. (3) Implementacion de la intervencion por medio de modulos en el topico de Equilibrio Termodinamico y Estatica de Fluidos. (4) Y la realizacion de la pos prueba para analizar el impacto y la efectividad de la intervencion constructivista. En la segunda etapa se utilizo el metodo de investigacion cualitativo, por medio de una entrevista semiestructurada que partio de la elaboracion de un mapa conceptual y se finalizo con un analisis de datos conjuntamente. El desarrollo de este estudio permitio encontrar "misconceptions" y lagunas conceptuales a partir del conocimiento previo de los estudiantes participantes en los temas trabajados, que fueron atendidos en el desarrollo de las distintas actividades inquisitivas que se presentaron en el modulo constructivista. Se encontro marcadas diferencias entre la pre y pos prueba en los temas, esto se debio al requerimiento de habilidades abstractas para el tema de Estatica de Fluidos y al desarrollo intuitivo para el tema de Equilibrio Termodinamico, teniendo mejores respuestas en el segundo. Los participantes demostraron una marcada evolucion y/o cambio en sus estructuras de pensamiento, las pruebas estadisticas

    Full Text Available Se evaluó la eficiencia de dos lagunas tapadas, diseñadas para tratar los residuales de las granjas porcinas P-3 y T-2.1 _pertenecientes a la Asociación de Porcicultores de Yucatán, México_, con el objetivo de verificar la factibilidad de implementar en Cuba esta tecnología. Los indicadores físico-químicos y microbiológicos de los efluentes fueron determinados en el momento de su entrada y su salida de los digestores, y a su salida del lago de estabilización. El digestor de la granja P-3 logró remover más del 90 % de la demanda química de oxígeno (DQO y hasta el 71 % de los sólidos suspendidos totales (SST presentes; mientras que el digestor de la granja T-2.1 alcanzó una remoción del 78 % en la DQO y el 62 % de los SST. Los análisis sanitarios indicaron que las bacterias coliformes totales presentaron una disminución importante, de 2,4 x 108 a 1,7 x 103 en la granja P-3 y de 4,2 x 107 a 2,7 x 103 en la granja T-2.1. En ambas lagunas, los huevos de helmintos mostraron una reducción del 100 %. Se concluye que las lagunas tapadas tuvieron un adecuado desempeño en el tratamiento de los residuales porcinos, y que esta tecnología es factible de ser empleada en Cuba.

    Full Text Available En la laguna de Chingaza (3265 m alt. Cordillera Oriental Colombiana, se realizaron muestreos de fitoplancton, mediciones de temperatura, oxígeno y parámetros físicos y químicos. La comunidad de fitoplancton comprende principalmente Desmidiaceae, Bacillariophyceae, y Cyanophyceae: La Desmidiacea Closterium sp. es la dominante durante la mayor parte del muestreo, pero en octubre (1989 la Cianofícea Oscillatoria sp. es la más significativa. En esta misma época la laguna presenta estratificación térmica y deficiencia de nitrógeno en sus aguas. Debido a los bajos valores en la relación nitrógeno/fósforo, conductividad, sólidos disueltos, acidez y ciertos organismos indicadores la laguna de chingaza es oligotrófica. At the Chingaza pond (3.265 m alt., located on the eastern Colombian cordillera, samples and measurements of temperature, oxygen, and physical-chemical parameters were taken. Phytoplankton community mainly consisted of Desmidiaceae, Bacillariophyceae, and Cyanophceae. Desmidiaceae species dominated in most samples, but in october (1989 Oscillatoria sp. (Cyanophyceae was the most abundant species. During the latter period the laguna exhibited strong thermal stratification and its inorganic nitrogen content was extremely low. It is believed that this is a good example of an oligotrophic pond given the presence of certain bioindicators, the low nitrogen/phosphorus ratio, conductivity, and quantity of suspended solids.

    2015-01-01

    During the accident occurred in Fukushima Daiichi Nuclear Power Station in Japan, the onsite and offsite electrical systems were affected and lost for a long time with irreversible consequences, therefore, the Mexican Regulatory Body known as the National Commission for Nuclear Safety and Safeguards (CNSNS: for its acronym in Spanish) has taken several actions to review the current capacity of the electrical systems installed at Laguna Verde NPP to cope with an event beyond of the design basis. The first action was to require to Laguna Verde NPP the compliance with Information Notice 2011-05 'Tohoku-Taiheiyou-Oki earthquake effects on Japanese Nuclear Power Plants' and with 10 CFR 50.54 'Conditions of licenses' section 'hh', both documents were issued by the United States Nuclear Regulatory Commission (USNRC). Additionally, CNSNS has taken into account the response actions emitted by other countries after the Fukushima accident. This involved the review of documents generated by Germany, Canada, United Arab Emirates, Finland, France, the United Kingdom and the Western European Nuclear Regulator's Association (WENRA). CNSNS made special inspections to verify the current capacity of the electrical systems of AC and DC. As a result of these inspections, CNSNS issued requirements that must be addressed by Laguna Verde NPP to demonstrate that it has the capacity to cope with events beyond the design basis. Parallel to the above, Mexico has participated in the Ibero-american Forum to address matters related to the 'Resistance Tests', the evaluations of the Forum have reached similar conclusions to those required by European Nuclear Safety Regulators Group (ENSREG), under the format proposed by WENRA. The actions carried out here are closely linked to the requirements established by the USNRC. It is also important to mention that: 1) the Extended Power Up-rate project was implemented in both Units of the Laguna Verde NPP before

    2018-03-01

    The newly introduced da Vinci Xi Surgical System hopes to address the shortcomings of its predecessor, specifically robotic arm restrictions and difficulty working in multiple quadrants. We compare the two robot platforms in multiquadrant surgery at a major colorectal referral center. Forty-four patients in the da Vinci Si group and 26 patients in the Xi group underwent sigmoidectomy or low anterior resection between 2014 and 2016. Patient demographics, operative variables, and postoperative outcomes were compared using descriptive statistics. Both groups were similar in age, sex, BMI, pelvic surgeries, and ASA class. Splenic flexure was mobilized in more (p = 0.045) da Vinci Xi cases compared to da Vinci Si both for sigmoidectomy (50 vs 15.4%) and low anterior resection (60 vs 29%). There was no significant difference in operative time (219.9 vs 224.7 min; p = 0.640), blood loss (170.0 vs 188.1 mL; p = 0.289), length of stay (5.7 vs 6 days; p = 0.851), or overall complications (26.9 vs 22.7%; p = 0.692) between the da Vinci Xi and Si groups, respectively. Single-dock multiquadrant robotic surgery, measured by splenic flexure mobilization with concomitant pelvic dissection, was more frequently performed using the da Vinci Xi platform with no increase in operative time, bleeding, or postoperative complications. The new platform provides surgeons an easier alternative to the da Vinci Si dual docking or combined robotic/laparoscopic multiquadrant surgery.

    Full Text Available Neste artigo pretende-se abordar especificamente a relação que se pode estabelecer entre o museu e a comunidade através da valorização, tratamento, divulgação, registo e proteção do património cultural imaterial (PCI. Para tal, apresenta-se como estudo de caso duas exposições realizadas pelo Museu da Terra de Miranda (Miranda do Douro através das quais se pretende destacar conhecimentos e saberes-fazeres subjacentes aos objetos e às coleções, situando simultaneamente os mesmos no seu contexto funcional. Neste âmbito, pretende-se estabelecer uma relação mais estreita entre os aspetos material e imaterial dentro do contexto museológico, evidenciando a importância da presença do campo imaterial na interpretação e compreensão das coleções. Procurar-se-á, através dos exemplos abordados, criar um espaço de reflexão sobre a importância de uma prática museológica de cariz participativo, encabeçado por uma mudança de paradigma, preconizada pela UNESCO através da Convenção da salvaguarda do Património Cultural Imaterial e que se expressa na participação dos atores sociais/protagonistas no tratamento do PCI.

    Full Text Available Francisco de Miranda es una de las grandes figuras emblemticas de la Historia de Venezuela. En nuestro medio le consideramos el adalid de la libertad continental en contra de la Monarquía hispnica. Hace doscientos años que intentó invadir a Venezuela y fracasó (1806; aunque contribuyó a crear las condiciones para la transición de colonia a republica. Aquí llevamos a cabo un acercamiento a su vida como conspirador bajo la dicotomía y paradoja de servir tanto a los intereses geopolíticos ingleses como a la causa de la libertad republicana.

  18. Factor XI and XII as antithrombotic targets.

    Arterial and venous thrombosis are major causes of morbidity and mortality, and the incidence of thromboembolic diseases increases as a population ages. Thrombi are formed by activated platelets and fibrin. The latter is a product of the plasma coagulation system. Currently available anticoagulants such as heparins, vitamin K antagonists and inhibitors of thrombin or factor Xa target enzymes of the coagulation cascade that are critical for fibrin formation. However, fibrin is also necessary for terminating blood loss at sites of vascular injury. As a result, anticoagulants currently in clinical use increase the risk of bleeding, partially offsetting the benefits of reduced thrombosis. This review focuses on new targets for anticoagulation that are associated with minimal or no therapy-associated increased bleeding. Data from experimental models using mice and clinical studies of patients with hereditary deficiencies of coagulation factors XI or XII have shown that both of these clotting factors are important for thrombosis, while having minor or no apparent roles in processes that terminate blood loss (hemostasis). Hereditary deficiency of factor XII (Hageman factor) or factor XI, plasma proteases that initiate the intrinsic pathway of coagulation, impairs thrombus formation and provides protection from vascular occlusive events, while having a minimal impact on hemostasis. As the factor XII-factor XI pathway contributes to thrombus formation to a greater extent than to normal hemostasis, pharmacological inhibition of these coagulation factors may offer the exciting possibility of anticoagulation therapies with minimal or no bleeding risk.

  19. ASME section XI: rules for inservice inspection of nuclear power plants -an introspection

    Section XI of the ASME BPV code is addressed to the examination, test and inspection requirements of the components of nuclear power plants (NPPs). Since its inception in 1970, this code section has undergone vast changes -probably the most among other ASME BPV code sections. Section XI is full fledged and lays down requirements with regard to all preservice inspections, inservice inspection, repair and replacement of components, tests of system etc. Tarapur Atomic Power Station (TAPS) has the distinction of being one of the earliest BWR type NPPs in the world that has an inservice inspection programme organised in line with the ASME section XI requirements. This paper summarises the experiences gained from time to time using this code section and a few suggestions to prospective users. An effort is also made to explain the philosophy of inservice inspection from ASME section XI point of view. 3 refs.

    Full Text Available Au Portugal la « littérature de colportage » est appelée « literatura de cordel », « folhas volantes » ou « folhetos ». Dans la région Terra de Miranda, à l'extrême nord-est du Portugal, ces livres populaires ont circulé jusqu'à la moitié du XX siècle mais, malheureusement, ils ont presque totalement disparu. Dans cet article, guidés par la mémoire et le savoir d'une conteuse, on essaiera de retrouver quelques traces de ces « folhetos » : leurs caractéristiques techniques et poétiques, les sujets les plus importants et la langue (étant donné que dans cette région on parle aussi le mirandais.

    By means of the use of the performance evaluation of power system efficiencies (PEPSE) code was modeled the vapor cycle of the nuclear power station of Laguna Verde to reproduce the nuclear plant behavior to conditions of thermal power, licensed at present (2027 MWt); with the purpose of having a base line before the implementation of the project of extended power increase. The model of the gauged vapor cycle to reproduce the nuclear plant conditions makes use of the PEPSE model, design case of the vapor cycle of nuclear power station of Laguna Verde, which has as main components of the model the great equipment of the vapor cycle of Laguna Verde. The design case model makes use of information about the design requirements of each equipment for theoretically calculating the electric power of exit, besides thermodynamic conditions of the vapor cycle in different points. Starting from the design model and making use of data of the vapor cycle measured in the nuclear plant; the adjustment factors were calculated for the different equipment s of the vapor cycle, to reproduce with the PEPSE model the real vapor cycle of Laguna Verde. Once characterized the model of the vapor cycle of Laguna Verde, we can realize different sensibility studies to determine the effects macros to the vapor cycle by the variation of certain key parameters.

  6. The Obama - Xi Accord: A Need for Further Action

    Science.gov (United States)

    Tribett, W. R.; Hope, A. P.; Canty, T. P.; Salawitch, R. J.

    2015-12-01

    Presidents Barrack Obama of the United States and Jinping Xi of China recently announced a bilateral framework to reduce the total carbon emissions of their respective countries. The U.S. agreed to reduce annual carbon emissions such that by 2025, emissions would be 27% below 2005 levels. China agreed to achieve peak carbon emissions around 2030 coupled with a best effort to peak early. Here we analyze the implications of the Obama-Xi accord for total global carbon emissions (GCE) out to year 2060, using projections of population, economic growth, and carbon intensity for the rest of the world as well as various assumptions regarding how emissions from the U.S. and China will evolve after the timeframe of the Obama-Xi accord. Our GCE projections will be compared to those of the four Representative Concentration Pathway (RCP) emission scenarios used in the IPCC Fifth Assessment Report (AR5). The Obama-Xi accord is shown to be a meaningful first step: if followed, the actual GCE will likely fall below RCP 8.5 between now and 2060. The U.S., China, and rest of the world presently emit 4.5, 2.0, and 1.1 tonne of carbon per person per year (tpy), respectively. We show that if the world's nations adopt a strategy of "Contraction and Convergence", such that per capita emission for each country reaches 1.0 tpy by 2060, actual GCE will approach that of RCP 4.5 by year 2060. Such action may be needed to reduce the risk of the most dire global warming forecasts within IPCC AR5.

    The logic of the xi-scaling analysis of inclusive lepton-hadron scattering is reviewed with the emphasis on clarifying what is assumed and what is predicted. The physics content of several recent papers, which purport to criticize this analysis, in fact confirm its validity and utility. For clarity, concentration is placed on the orthodox operator product analysis of electroproduction, local duality and precocious scaling. Other physics discussed includes the successes of QCD in the rate of charm production in muon inelastic scattering and in the energy--momentum sum rule. Gluons

  9. Ceratopetalum (Cunoniaceae) fruits of Australasian affinity from the early Eocene Laguna del Hunco flora, Patagonia, Argentina.

    2017-03-01

    Radially symmetrical, five-winged fossil fruits from the highly diverse early Eocene Laguna del Hunco flora of Chubut Province, Patagonia, Argentina, are named, described and illustrated. The main goals are to assess the affinities of the fossils and to place them in an evolutionary, palaeoecological and biogeographic context. Specimens of fossil fruits were collected from the Tufolitas Laguna del Hunco. They were prepared, photographed and compared with similar extant and fossil fruits using published literature. Their structure was also evaluated by comparing them with that of modern Ceratopetalum (Cunoniaceae) fruits through examination of herbarium specimens. The Laguna del Hunco fossil fruits share the diagnostic features that characterize modern and fossil Ceratopetalum (symmetry, number of fruit wings, presence of a conspicuous floral nectary and overall venation pattern). The pattern of the minor wing (sepal) veins observed in the Patagonian fossil fruits is different from that of modern and previously described fossil Ceratopetalum fruits; therefore, a new fossil species is recognized. An apomorphy (absence of petals) suggests that the fossils belong within crown-group Ceratopetalum . The Patagonian fossil fruits are the oldest known record for Ceratopetalum . Because the affinities, provenance and age of the fossils are so well established, this new Ceratopetalum fossil species is an excellent candidate for use as a calibration point in divergence dating studies of the family Cunoniaceae. It represents the only record of Ceratopetalum outside Australasia, and further corroborates the biogeographic connection between the Laguna del Hunco flora and ancient and modern floras of the Australasian region. © The Author 2017.

    In 2010 the nuclear power plant of Laguna Verde will implement the extended power upbeat in both units of the plant. Agree with methodology of NEDC-33004P-A, (constant pressure power up rate), and the source term of core, for accidents evaluations, were increased in proportion to the ratio of power level. This means that for the case of a design basis accident of loss of coolant an increase of power of 15% originated an increase of 15% in dose to main control room. Using the method of NEDC-33004P-A to extended power upbeat conditions was determined that the dose value to main control room is very near to regulatory limit established by SRP 6.4. By the above and in order to recover the margin, the nuclear power plant of Laguna Verde will calculate an alternative source term following the criteria established in RG 1.183 (alternative radiological source term for evaluating DBA at nuclear power reactor). This approach also have a more realistic dose value using the criterion of 10-CFR-50.67, in addition is predicted to get the benefit of additional operational flexibilities. This paper present the proposal of implementing the alternative source term in Laguna Verde. (Author)

    The nuclear power plant of Laguna Verde located in the Gulf of Mexico, completes in this 2009, nineteen years to produce by nuclear means 4.78% of the electric power that Mexico requires daily. During this time, the Unit 1 has generated more of 88.85 million mega watt-hour and the Unit 2 more of 69.48 million mega watt-hour with an availability average of 83.55%. Derived of their operation cycles, the nuclear power plant has generated (as any other installation of its type) radioactive wastes of low activity that at the moment are temporarily stored in the site. Due to the life cycle of the nuclear power plant, actually has become necessary to begin a project series focused to continue guaranteeing the storage of these wastes, guarantee that is a license requirement for the operation of this nuclear installation before the National Commission of Nuclear Security and Safeguards. The Federal Commission of Electricity beginning a project that allows continue guaranteeing space of sufficient storage for the wastes that the nuclear power plant of Laguna Verde could generate for the rest of its useful life, this project consisted on a process of physical volume reduction of dry solid radioactive wastes denominated super compacting, it has made possible to reduce the volume that these wastes occupy in the temporary storage noted Dry Solid Radioactive Wastes Deposit located inside the site that occupies the nuclear power plant of Laguna Verde. This work presents the super compacting results, as well as a description of the realization of this task until concluding with the super compacting of 5,854 drums with dry solid radioactive waste of low activity. We will enunciate which were the radiological controls that the Department of Radiological Protection of the nuclear power plant of Laguna Verde applied to this work that was realized for first time in Mexico and the nuclear power plant.

    The aims of this study were to compare the perioperative outcomes of da Vinci Xi to Si during robotic-assisted partial nephrectomy (RAPN) and to discuss the feasibility of our novel port placement scheme for the da Vinci Xi platform, to overcome the existing kinetic and technical difficulties we faced with the linear port placement in patients with a small body habitus. A retrospective data analysis of patients who underwent RPN using da Vinci Xi (n = 18) was carried out. The outcomes of the Xi group were compared with the Si group (n = 18) selected using a case-matched methodology. For da Vinci Xi, we applied the universal linear port placement in 12 patients and our modified port placement in the remaining 6 patients. The Xi group had a shorter mean docking time of 17.8 ± 2.6 min compared to the Si group of 20.5 ± 2.1 min (p = 0.002); otherwise, no significant difference was present with regard to the remaining perioperative variables (p > 0.05). The modified Xi port placement had a shorter mean console time of 70.8 ± 9.7 min compared to the universal linear port placement of 89.3 ± 17.2 min (p = 0.03). Moreover, it provided a broader field of vision with excellent robotic arms movement, minimizing collisions and allowing an easier and comfortable surgical assist. Da Vinci Xi appears to be feasible and safe during RPN with similar outcomes to Si. The novel Xi port placement makes surgery easier in patients with low BMI.

This system is made up of 5 subsystems operating individually and are also related 1) human performance; 2) referential comparison or benchmarking; 3) self-assessment; 4) corrective action and 5) external operating experience. Five subsystems that plan, generate, capture, manage, communicate and protect the knowledge generated during the processes execution of nuclear power plant of Laguna Verde, as well as from external sources. The target set in 2007 was to increase the intellectual capital to always give response to meeting the security requirements, but creating a higher value to quality, customer, environment protection and society. In brief each of them, highlighting the objective, expectations management, implementation and some benefits. At the end they will describe two study cases selected to illustrate these cases as the organization learns by their continuous improvement system. (Author)

  6. Waterbirds and human-related threats to their conservation in Laguna Cuyutlán, Colima, México

    2009-06-01

    Full Text Available Laguna Cuyutlán, the only large wetland in a span of 1 150 km along the Pacific coast of México, has been neglected as to its importance for waterbird conservation. At least 25 waterbird species nest there, with some of their colonies being very relevant, and at least 61 waterbird species use the lagoon during their nonbreeding season. This lagoon has been subject to several structural modifications, including levees and artificial channels which connect it to the sea, while water supply from continental sources has diminished, although its role has not been assessed yet. Salt extraction and artisanal fishery, the main economic activities, do not seem to pose a threat to waterbirds. Among potential threats to this acquatic ecosystem, are the raw sewage discharges that exist near urban areas, and pesticides from the surrounding agricultural lands might reach the lagoon. Seemingly, the most serious threat comes from waterway development in connection with a re-gasification plant to be built, and planned future port expansion, which could potentially increase water levels and alter important habitats for nesting and foraging. We recommend that: the area be declared an Important Bird Area; the development of the re-gasification plant and future port includes a levee to prevent alterations in water level in the remaining sections of the lagoon; supply of exogenous chemicals and waste products be prevented and monitored; alleged benefits from water interchange between the lagoon and the sea through artificial channels should be re-evaluated; and the role of fresh water supplies to the lagoon should be paid attention to.

    Full Text Available White goby (Glossogobius giuris Hamilton 1822 is an omnivorous, native fish species which can be found in Laguna de Bay and its tributaries, and in other bodies of water in the Philippines. Deteriorating water quality, unsustainable fishing practices, aquaculture and predation by introduced invasive species are threatening the population of white goby and other native fish species in Laguna de Bay. This study was conducted to correlate select physico-chemical parameters of lake water and zooplankton abundance, and to assess white goby population based on fishers’ perception. Water samples were collected in three sites in June, September and December 2014. Twenty one zooplankton species belonging to 12 families were identified. The most abundant and frequently encountered zooplankton species is Eurytemora affinis Poppe 1880. Zooplanktons were most abundant in June and lowest in September. Key informant interviews with local fishers revealed that white goby population was abundant in April to August while catch report showed that fish catch is abundant in June and least during December. The fish abundance in April to June could be attributed to high productivity especially in summer season. The fishers perceived that the population of white goby was declining mainly due to water pollution, aquaculture, and predation by invasive alien species. A multi-stakeholder sustainable watershed management should be adapted to improve the water quality and extinction of native fish species in Laguna de Bay.

  8. Determination of heavy metals and other elements by Neutron Activation Analysis in sediment cores of laguna Mar Chiquita (Cordoba, Argentina)

    Larizzatti, Flavio Eduardo

    2001-01-01

    Laguna Mar Chiquita is one of the largest water bodies of South America. It is a big lake of saline waters, and its geographic localization is SOMS' S, 62 deg 30' W, about 150 km Northwest of Cordoba, Argentina. Due to its large variability of hydrological budget, surface and water levels produced periods of low stands (LLP) and high stands (HLP). This fluctuation of water level also produces substantial changes in the water salinity. The principal tributary of the Laguna Mar Chiquita is Dulce River and also receives water from two other rivers: Suquia and Xanaes. The Suquia River drains in a small satellite lake, the Laguna del Plata. The purpose of the present work was to investigate the sediment composition of the Laguna Mar Chiquita (2 sediment cores) and del Plata (one sediment core) by using Neutron Activation Analysis (NAA) technique. The three 60 cm long sediment cores, sliced each 2 cm, were analyzed and 26 elements were determined (As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, La, Lu, Na, Nd, Rb, Sb, Sc, Se, Sm, Ta, Tb, Th, U, Yb, Zn e Zr). Other complementary techniques were utilized: macro elements (Al, Ca, Fe, K, Mg, Mn, Na, P, Si, Ti) were determined by X-ray fluorescence, and the mineralogical composition of the sediments was determined by X-ray diffraction. The results obtained did not show any indication of anthropic contribution in the sediment composition, and concentration of the majority of the elements analyzed is uniform along the entire profile of the analyzed core. Statistical analysis of elemental concentrations (Cluster Analysis) reflects that in Laguna del Plata the fine fractions of the sediments is dominated by detrital minerals, while in the Laguna Mar Chiquita, the neo formed minerals are the principal components. In both lakes, it was possible to identify compositional variations in the sediment segments, which may correspond to temporal fluctuations in the sedimentation conditions. The statistical analysis associated to sedimentation

    2007-01-01

    The radiative decay of a hyperon into a light hyperon and a photon allows to study the structure of the electroweak interaction of hadrons. For this purpose, the decay asymmetry is an appropriate observable. It describes the distribution of the daughter hyperon with respect to the polarization $vec{P}$ of the mother hyperon by $dN / d cos(Theta) propto 1 + alpha |vec{P}| cos(Theta)$, where $Theta$ is the angle between $vec{P}$ and the momentum of the daughter hyperon. The radiative decay $Xi^0 to Lambda gamma$ is of particular interest since all calculations at quark level predict a positive decay asymmetry whereas two existing measurements result in a negative value of $alpha_{Lambda gamma} = -0.73 pm 0.17$. The goal of the analysis presented here was to verify these results and to improve the accuracy of the decay asymmetry measurement. In addition, the decay asymmetry of the similar decay $Xi^0 to Sigma^0 gamma$ was measured, and the well-known decay $Xi^0 to Lambda pi^0$ was used to test the analysis str...

  14. History and current safety measures at Laguna Palcacocha, Huaraz, Peru

    Laguna Palcacocha is a large glacier lake in the Cordillera Blanca, Peru, located in the Quillcay catchment, above the city of Huaraz, the local capital. On 13 December 1941, the moraine dam lake collapsed, probably after having been impacted by a large ice avalanche, and triggered a major outburst flood. This GLOF destroyed about a third of the city of Huaraz, causing about 2,000 casualties and is therefore one of the deadliest glacier lake outbursts known in history. In 1974, the Glaciology Unit of Peru, responsible for the studying, monitoring and mitigation works related to glacier hazards installed a reinforcement of the natural moraine dam of the newly filled Laguna Palcacocha, with an artificial drainage channel at 7 m below the crest of the reinforced dam. At that time, the lake had an area of 66,800 m2 and a volume of 0.5 x 106 m3. During the past decades, in the course of continued glacier retreat, Laguna Palcacocha has undergone an extreme growth. In February 2016, the lake had an area of 514,000 m2 (7.7 times the area of 1974) and a volume of more than 17 x 106 m3 (more than 34 times the volume of 1974). At the same time, the city of Huaraz, located 20 km downstream of the lake, grew significantly after its almost complete destruction by the 1970 earthquake. Today, about 120,000 people are living in the city. Due to the persisting possibility for large ice avalanches directly above the Palcacocha lake, this constitutes a high-risk situation, requiring new hazard and risk mitigation measures. As an immediate temporal measure, in order to bridge the time until the realization of a more permanent measure, a syphoning system has been installed in 2011, using about ten 700-m pipes with a 10-inch (25.4 cm) diameter. The aim of this syphoning attempt is to lower the lake level by about 7 m, and therefore reduce the lake volume on the one hand, and also reach a higher dam freeboard. However, the system is less effective than assumed, currently the lake level

    The polarization of the muon in the decay K 0 /sub L/ → π - μ + ν/sub μ/ was measured as a function of q 2 , the four-momentum transferred to the lepton pair. The kinematic information was used to compute the polarization expected on the basis of various assumed values of the form factor xi(q 2 ). By comparing the interpolated curve of the polarization as a function of xi(q 2 ) to the experimentally measured polarization, one has determined xi(q 2 ) as a function of q 2 . If one parameterizes the q 2 dependence of xi by xi(q 2 ) = xi(0) + Λ q 2 /m 2 /sub π/, then xi(0) = 0.178 +- 0.105 - 3.80 Λ

    The weak radiative decay $Xi^0 -> \\Lambda e^+ e^- $ has been detected for the first time. We find 412 candidates in the signal region, with an estimated background of $15pm 5$ events. We determine the branching fraction ${cal{B}}(\\Xi^0 -> \\Lambda e^+ e^- ) = [7.6pm 0.4({m stat})pm 0.4({m syst})pm 0.2({m norm})] imes 10^{-6}$, consistent with an internal bremsstrahlung process, and the decay asymmetry parameter $\\alpha_{\\Xi \\Lambda ee} = -0.8pm 0.2$, consistent with that of $\\Xi^0 -> \\Lambda \\gamma$. The charge conjugate reaction $\\overline{\\Xi^{0}} -> \\overline{\\Lambda} e^+ e^- $ has also been observed.

    Full text: An archaeological site with several funerary houses built in the cliffs of the Laguna de los Condores by the Chachapoya people was discovered in 1997 in the cloud forest at a sea level of 2500 m in the Amazonas/San Martin area in Peru. The Chachapoya people and their culture is not fully understood until now and some myths entwine around the origin of that South American ancient civilisation. The Chachapoya are described as people of warriors, which were finally subdued by the Incas. A typical characteristic of their culture is the special burial of their dead in funeral bundles containing the remains of the bodies. At the Laguna de los Condores more that 200 mummies have been found and transferred to Leymebamba. During the rescue work of the mummies, which were in danger to be destroyed by looters, it turned out that two different burial patterns could be detected. It is assumed, that after conquering of the Chachapoyas, the Inca people took over also the burial cliff houses and used it for their own burials. The Incas themselves were subdued by the Spanish Conquistadors in 1532 AD. In order to shed light on the transition from the Chachapoya to the Inka dominance, which is connected with the history of the Laguna de los Condores funeral site, a multidisciplinary project between archaeologists, anthropologists and physicists has been started. VERA contributes to this project with several radiocarbon dates of archaeological objects and of the mummies from this Chachapoya/Inca site. (author)

  5. A statistical study of high coronal densities from X-ray line-ratios of Mg XI

    1991-01-01

    An X-ray line-ratio density diagnostic was applied to 50 Mg XI spectra of flaring active regions on the sun recorded by the Flat Crystal Spectrometer on the SMM. The plasma density is derived from R, the flux ratio of the forbidden to intercombination lines of the He-like ion, Mg XI. The R ratio for Mg XI is only density sensitive when the electron density exceeds a critical value (about 10 to the 12th/cu cm), the low-density limit (LDL). This theoretical value of the low-density limit is uncertain as it depends on complex atomic theory. Reported coronal densities above 10 to the 12th/cu cm are uncommon. In this study, the distribution of R ratio values about the LDL is estimated and the empirical values are derived for the 1st and 2nd moments of this distribution from 50 Mg XI spectra. From these derived parameters, the percentage of observations is derived which indicated densities above this limit.

    This work presents the results of the seismic qualification tests applied to the fans that will be installed in the control panels of the three divisions of the diesel generators of the nuclear power plant (NPP) of Laguna Verde, Unit-1 and Unit-2. This seismic qualification process of the fans was carried out using two specimens that were tested in the seismic table (vibrating) of the Engineering Institute of Universidad Nacional Autonoma de Mexico (UNAM), in accordance with the requirements of the standard IEEE 344-1975, to satisfy the established requirements of seismic qualification in the technical specifications and normative documents required by the nuclear standards, in order to demonstrate its application in the diesel generators Divisions I, II and III of the NPP. The seismic qualification tests were developed on specimens that were retired of the NPP of Laguna Verde recently with a service life of 7.75 years. (Author)

  7. Summertime ozone formation in Xi'an and surrounding areas, China

    Full Text Available In this study, the ozone (O3 formation in China's northwest city of Xi'an and surrounding areas is investigated using the Weather Research and Forecasting atmospheric chemistry (WRF-Chem model during the period from 22 to 24 August 2013, corresponding to a heavy air pollution episode with high concentrations of O3 and PM2.5. The model generally performs well compared to measurements in simulating the surface temperature, relative humidity, and wind speed and direction, near-surface O3 and PM2.5 mass concentrations, and aerosol constituents. High aerosol concentrations in Xi'an and surrounding areas significantly decrease the photolysis frequencies and can reduce O3 concentrations by more than 50 µg m−3 (around 25 ppb on average. Sensitivity studies show that the O3 production regime in Xi'an and surrounding areas is complicated, varying from NOx to VOC (volatile organic compound-sensitive chemistry. The industrial emissions contribute the most to the O3 concentrations compared to biogenic and other anthropogenic sources, but neither individual anthropogenic emission nor biogenic emission plays a dominant role in the O3 formation. Under high O3 and PM2.5 concentrations, a 50 % reduction in all the anthropogenic emissions only decreases near-surface O3 concentrations by about 14 % during daytime. The complicated O3 production regime and high aerosol levels pose a challenge for O3 control strategies in Xi'an and surrounding areas. Further investigation regarding O3 control strategies will need to be performed, taking into consideration the rapid changes in anthropogenic emissions that are not reflected in the current emission inventories and the uncertainties in the meteorological field simulations.

    75 photoelectric UBV-observations of xi Boo AB were obtained during 45 nights in 1980. Real light variations of several thousandths of magnitude are revealed. Moreover, the variations observed in two nights were resembling flares. Both recent and published data on HD 1835 together with Wilson's observations of H and K Ca II lines in the spectra of xi Boo A, xi Boo B and HD 1835 are used for the search of periodicities. The periodicities are present in variations of light and Ca II -emission. Periodicities are more prominent in light variations (periods are 10 days for xi Boo AB and 7.66 days for HD 1835). In H and K Ca II lines the duration of cycles is different but the basic period is the same as in light variations. Therefore, the basic period (interpreted as the period of star roration) can be revealed only from a very long run of H and K Ca II observations (approximately 150). Light variations of xi Boo AB are probably due to the A-component since the basic period of Ca II-variations in xi Boo A is approximately the same (10 days). The basic period of Ca II-variations in xi Boo B is considerably larger.

    A new digital Cerenkov viewing device (DCVD) with high ultraviolet light sensitivity has been developed. Field measurements on BWR spent fuel at Laguna Verde Nuclear Power Plant Unit 2 resulted in new Cerenkov information on GE9 and GE12 spent fuel assemblies. Off-alignment measurements show: quantitative differences in the degree of light collimation from between the fuel rods; lack of light collimation from water rods; and decreased light collimation from partial length rod positions. Hidden rods could also be detected in off-angle views. The results indicate that it may be possible to detect missing partial-length fuel rods in GE12 fuel assemblies. The new DCVD was able to verify low burnup, long-cooled, natural uranium GE6 fuel assemblies

    1985-12-01

    Plasma samples of 125 patients from 80 kindreds with hereditary plasma thromboplastin antecedent (PTA, factor XI) deficiency were tested by factor XI radioimmunoassay (RIA) and electroimmunoassay (EIA) in an attempt to detect variant molecules. Ninety-six patients (70 kindreds) were Jewish, and 29 (10 kindreds) were of other ethnic backgrounds, namely, Japanese, black American, Korean, Arab, Indian, and English. Seventy-eight patients were homozygotes, and 47 were heterozygotes. Both non-Jewish homozygotes and heterozygotes had lower factor XI activity than respective Jewish subjects. Twenty-eight homozygotes whose factor XI clotting activities (XI:C) were 1.5% to 13% had factor XI-related antigen (XI:RAG) levels less than 10% by EIA. In 72 homozygotes, including 22 patients who were also tested with EIA, XI:C was 2.9% +/- 3.0% (mean +/- SD) and XI:RAG tested by RIA, 2.9% +/- 3.0%. In 47 heterozygotes, XI:C and XI:RAG tested by RIA were 51.9% +/- 16.6% and 51.0% +/- 16.2%, respectively. Similar results were obtained when only unrelated patients (62 homozygotes and 27 heterozygotes) were analyzed. There was a highly significant correlation between XI:C and XI:RAG (RIA) in 38 homozygotes and 47 heterozygotes (r = 0.94, n = 85, P less than 0.001). Thus, we failed to identify functionally abnormal factor XI molecules (CRM+ variant) in these patients with hereditary factor XI deficiency.

    The da Vinci Xi Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA) has been released in 2014 to facilitate minimally invasive surgery. Novel features are targeted towards facilitating complex multi-quadrant procedures, but data is scarce so far. Perioperative data of patients who underwent robotic general surgery with the da Vinci Xi system within the first 6 month after installation were collected and analyzed. The gastric bypass procedures performed with the da Vinci Xi Surgical System were compared to an equal amount of the last procedures with the da Vinci Si Surgical System. Thirty-one foregut (28 Roux-en-Y gastric bypasses), 6 colorectal procedures and 1 revisional biliary procedure were performed. The mean operating room (OR) time was 221.8 (±69.0) minutes for gastric bypasses and 306.5 (±48.8) for colorectal procedures with mean docking time of 9.4 (±3.8) minutes. The gastric bypass procedure was transitioned from a hybrid to a fully robotic approach. In comparison to the last 28 gastric bypass procedures performed with the da Vinci Si Surgical System, the OR time was comparable (226.9 versus 230.6 min, p = 0.8094), but the docking time significantly longer with the da Vinci Xi Surgical System (8.5 versus 6.1 min, p = 0.0415). All colorectal procedures were performed with a single robotic docking. No intraoperative and two postoperative complications occurred. The da Vinci Xi might facilitate single-setups of totally robotic gastric bypass and colorectal surgeries. However, further comparable research is needed to clearly determine the significance of this latest version of the da Vinci Surgical System.

    Some aspects of thyroid function in rats whose blood lithium levels were maintained are investigated. At therapeutic levels during 1,5 to 2 months. Adult young male rats (isogenic Dutch-Miranda) of the same litter were randomly distributed into paired experimental and control groups of 3 animals. The animals were fed comercial chow and received tap water or LiCl 12,5 mM in distiled water to drink, ad-libitum. At the end of experimental period each animal received an intraperitoneal tracer dosis of I-131 (5-6 uCi), 72 h later their thyroids were removed, weighed and counted to determine the I-131 uptake. The pooled thyroids of each group were homogeneized and supernadant and particulate fractions were separed by centrifugation. TPO activity was determined in the pseudosolubilized particulate feaction. (Author) [pt

Este sistema ha presentado deficiencias en su operación, reflejadas en problemas organolépticos, hidráulicos y metabólicos. El sistema de lagunas del municipio de La Ceja está conformado por dos lagunas anaerobias y una laguna facultativa, que reciben las aguas residuales domésticas provenientes de un alcantarillado combinado. En los años 2003 y 2004, se realizaron mediciones de variables físicas, químicas y biológicas, incluyendo tres muestreos generales. El sistema funcionó deficientemente debido a problemas hidráulicos. La deficiencia del sistema estuvo acompañada de una baja remoción de nutrientes disueltos en la laguna facultativa asociada a un pobre desarrollo de la comunidad de microorganismos. El sistema presentó una remoción de carga orgánica del 75 %, relacionada principalmente con la sedimentación en las lagunas anaerobias.

    Nipple-sparing mastectomy (NSM) is increasingly popular for the treatment of selected breast cancers and prophylactic mastectomy. Surgical scarring and esthetic outcomes are important patient-related cosmetic considerations. Today, the concept of minimally invasive surgery has become popular, especially using robotic surgery. The authors report the first case of NSM using the latest version of the da Vinci Xi surgical system (Xi). The final incision used to remove the entire mammary gland was located behind the axillary line. In this position, hidden by the arm of the patient, the incision was not visible and was compatible with immediate breast reconstruction. © 2017 Wiley Periodicals, Inc.

    Building on the results achieved in the Pioneer shot series, the Los Alamos Trailmaster project is embarking on the Laguna foil implosion experiments. In this series a Mark-IX helical generator will be coupled to an explosively formed fuse opening switch, a surface-tracking closing switch, and a vacuum power flow and load chamber. In this paper the system design will be discussed and results from zero-, one-, and two-dimensional MHD simulations will be presented. It is anticipated that the generator will provide more than 10 MA of which ∼5.5 MA will be switched to the 5-cm-radius, 2-cm-high, 250-nm-thick aluminum foil load. This should give rise to a 1 μs implosion with more than 100 kJ of kinetic energy

    To study the status and source of aluminum (Al) contamination, a total of 21 sampling sites along six rivers near Xi'an City (Shaanxi province, China) were investigated during 2008-2010. The results indicated that the average concentration of total Al (Al(t)) in the six rivers increased by 1.6 times from 2008 to 2010. The spatial distribution of Al(t) concentrations in the rivers near Xi'an City was significantly different, ranged from 367 μg/L (Bahe River) to 1,978 μg/L (Taiping River). The Al(t) concentration was highest near an industrial area for pulp and paper-making (2,773 μg/L), where the Al level greatly exceeded the water quality criteria of both the USA (Criterion Continuous Concentration, 87 μg/L) and Canada (100 μg/L). The average concentration of inorganic monometric aluminum (Al(im)) was 72 μg/L which would pose threats to fishes and other aquatic lives in the rivers. The concentrations of exchangeable Al (Al(ex)) in the sediment of the Taiping River sampled were relatively high, making it to be an alternative explanation of increasing Al concentrations in the rivers near Xi'an City. Furthermore, an increasing Al level has been detected in the upstream watershed near Xi'an City in recent years, which might indicate another notable pollution source of Al.

  2. Ikaite precipitation in a lacustrine environment - implications for palaeoclimatic studies using carbonates from Laguna Potrok Aike (Patagonia, Argentina)

    The monoclinic mineral ikaite (CaCO3 · 6H2O) and its pseudomorphs are potentially important archives for palaeoenvironmental reconstructions. Natural ikaite occurs in a small temperature range near freezing point and is reported mainly from marine and only rarely from continental aquatic environments. Ikaite transforms to more stable anhydrous forms of CaCO3 after an increase in temperature or when exposed to atmospheric conditions. The knowledge about conditions for natural ikaite formation, its stable isotope fractionation factors and isotopic changes during transformation to calcite is very restricted. Here, for the first time, primary precipitation of idiomorphic ikaite and its calcite pseudomorphs are reported from a subsaline lake, Laguna Potrok Aike, in southern Argentina. The calculated stable oxygen isotope fractionation factor between lake water and ikaite-derived calcite (αPAI = 1.0324 at a temperature of 4.1 °C) is close to but differs from that of primarily inorganically precipitated calcite. Pseudomorphs after ikaite rapidly disintegrate into calcite powder that is indistinguishable from μm-sized calcite crystals in the sediment record of Laguna Potrok Aike suggesting an ikaite origin of sedimentary calcites. Therefore, the Holocene carbonates of Laguna Potrok Aike have the potential to serve as a recorder of past hydrological variation.

    Large samples of $\\Lambda$, $\\Sigma(1385)$ and $\\Xi(1321)$ hyperons produced in deep-inelastic muon scattering off a $^6$LiD target were collected with the COMPASS experimental setup at CERN. The relative yields of $\\Sigma(1385)^+$, $\\Sigma(1385)^-$, $\\bar{\\Sigma}(1385)^-$, $\\bar{\\Sigma}(1385)^+$, $\\Xi(1321)^-$, and $\\bar{\\Xi}(1321)^+$ hyperons decaying into $\\Lambda(\\bar{\\Lambda})\\pi$ were measured. The heavy hyperon to $\\Lambda$ and heavy antihyperon to $\\bar{\\Lambda}$ yield ratios were found to be in the range 3.8% to 5.6% with a relative uncertainty of about 10%. They were used to tune the parameters relevant for strange particle production of the LEPTO Monte Carlo generator.

    The project of extended increase of power responds to a necessity of electrical energy in the country, increasing the thermal exit of the reactors of the nuclear power plant of Laguna Verde of 2027 MWt to 2317 MWt. In order to support this transition, changes will make in the configuration of the reactor core and in the operation strategies of the cycle, also they will take initiatives to optimize the economy in fuel cycle. At present in both reactors of the nuclear plant of Laguna Verde fuel GE12 is used. The fuel GE14 presents displays with respect to the GE12, some improvements in the mechanical design and consequently in its performance generally. Between these improvements we can mention: 1. Spacers of high performance. 2. Shielding with barrier. 3. Filter for sweepings {sup d}ebris{sup a}nd 4. Fuel rods of minor partial length. The management of nuclear power plants has decided to introduce the use of fuel GE14 in Laguna Verde in the reload 14 for Unit 1 and of the reload 10 for Unit 2. The process of new introduction fuel GE14 consists of two stages, first consists on subjecting the one new design of fuel to the regulator organism in the USA: Nuclear Regulatory Commission, in Mexico the design must be analyzed and authorized by the National Commission of Nuclear Safety and Safeguards, for its approval of generic form, by means of the demonstration of the fulfillment with the amendment 22 of GESTAR II, the second stage includes the specific analyses of plant to justify the use of the new fuel design in a reload core. The nuclear plant of Laguna Verde would use some of the results of the security analyses that have been realized for the project of extended increase of power with fuel GE14, to document the specific analyses of plant with the new fuel design. The result of the analyses indicates that the reload lots are increased of 116-120 assemblies in present conditions (2027 MWt) to 140-148 assemblies in conditions of extended increase of power (2317 MWt

    In this work the main results of the simulation of overpressure events are presented using a model of the nuclear power plant of Laguna Verde developed for the RELAP/SCDAPSIM code. As starting point we have the conformation of a Laguna Verde model that represents a stationary state to similar conditions to the operation of the power station with Extended Power Up rate (EPU). The transitory of simulated pressure are compared with those documented in the Final Safety Analysis Report of Laguna Verde (FSAR). The results of the turbine shot transitory with and without by-pass of the main turbine are showed, and the event of closes of all the valves of main vapor isolation. A preliminary simulation was made and with base in the results some adjustments were made for the operation with EPU, taking into account the Operation Technical Specifications of the power station. The results of the final simulations were compared and analyzed with the content in the FSAR. The response of the power station to the transitory, reflected in the model for RELAP, was satisfactory. Finally, comments about the improvement of the model are included, for example, the response time of the protection and mitigation systems of the power station. (Author)

    Physical characterization and chemical analysis of settled dusts collected in Xi'an from November 2007 to December 2008 show that (1) dust deposition rates ranged from 14.6 to 350.4 g m -2 yr -1 . The average deposition rate (76.7 g m -2 yr -1 ) ranks the 11th out of 56 dust deposition rates observed throughout the world. The coal-burning power was the major particle source; (2) on average (except site 4), ∼10% of the settled dusts having size 70% having size <30 μm; (3) the concentrations for 20 out of 27 elements analyzed were upto 18 times higher than their soil background values in China. With such high deposition rates of dusts that contain elevated levels of toxic elements, actions should be taken to reduce emission and studies are needed to assess the potential impacts of settled particles on surface ecosystem, water resource, and human health in the area. - Research highlights: → High atmospheric dust deposition rate in Xi'an, Shaanxi, China. → Coal-burning power plan being a major source of particulate matter in Xi'an area. → High levels of toxic elements in the settled dusts. → Enrichment of heavy metals (e.g., Pb, Ni, Cu) in fine particles. - Atmospheric dust deposition rate is high and the levels of toxic elements associated with the settled dusts are elevated in Xi'an, Shaanxi, China.

    Robotic-assisted laparoscopic nephroureterectomy (RALNU) has been previously utilized for management of upper tract urothelial carcinoma. The da Vinci Xi surgical system was released in April of 2014. We describe our operative technique and early experience for RALNU using the da Vinci Xi system highlighting unique features of this surgical platform. A total of 10 patients with a diagnosis of upper tract urothelial carcinoma underwent RALNU using the da Vinci Xi system between April and November of 2014. A novel, oblique "in line" robotic trocar configuration was utilized to access the upper abdomen (nephrectomy portion) and pelvis (bladder cuff excision) without undocking. The port hopping feature of da Vinci Xi was utilized to facilitate optimal, multi-quadrant visualization during RALNU. Robotic-assisted laparoscopic nephroureterectomy was successfully completed without open conversion in all 10 patients. Mean operative time was 184 min (range 140-300 min), mean estimated blood loss was 121 cc (range 60-300 cc), and mean hospital stay was 2.4 days. Final pathology demonstrated high grade urothelial carcinoma in all patients. Surgical margins were negative in all patients. No intra-operative complications were encountered. One patient developed a pulmonary embolus after being discharged. No patients required a blood transfusion. Mean patient follow-up was 130 days (range 15-210 days). The use of da Vinci Xi with a novel, oblique "in line" port configuration and camera port hopping technique allows for an efficient and reproducible method for RALNU without the need for repositioning the patient or the robot during surgery.

    To predict the effects of the neutrons radiation and the thermal environment about the mechanical properties of the reactor vessel materials of the nuclear power plant of Laguna Verde, a surveillance program is implemented according to the outlines settled by Astm E185-02 -Standard practice for design of surveillance programs for light-water moderated nuclear power reactor vessels-. This program includes the installation of three irradiation capsules of similar materials to those of the reactor vessels, these samples are test tubes for mechanical practices of impact and tension. In the National Institute of Nuclear Research and due to the infrastructure as well as of the actual human resources of the Pilot Plant of Nuclear Fuel Assembles Production it was possible to realize the materials rebuilding extracted in 2005 of Unit 2 of nuclear power plant of Laguna Verde as well as the production, assemble and reassignment of the irradiation capsule made in 2006. At the present time the surveillance materials extracted in 2008 of Unit 1 of the nuclear power plant of Laguna Verde are reconstituting and the components are manufactured for the assembles of the irradiation capsule that will be reinstalled in the reactor vessel in 2010. The purpose of the present work is to describe the necessary components as well as its disposition during the assembles of the irradiation capsule for the surveillance program of the reactors vessel of the nuclear power plant of Laguna Verde.

    Large samples of {Lambda}, {Sigma}(1385) and {Xi}(1321) hyperons produced in the deep-inelastic muon scattering off a {sup 6}LiD target were collected with the COMPASS experimental setup at CERN. The relative yields of {Sigma}(1385){sup +}, {Sigma}(1385){sup -}, anti {Sigma}(1385){sup -}, anti {Sigma}(1385){sup +}, {Xi}(1321){sup -}, and anti {Xi}(1321){sup +} hyperons decaying into {Lambda}(anti {Lambda}){pi} were measured. The ratios of heavy-hyperon to {Lambda} and heavy-antihyperon to anti {Lambda} were found to be in the range 3.8 % to 5.6 % with a relative uncertainty of about 10 %. They were used to tune the parameters relevant for strange particle production of the LEPTO Monte Carlo generator. (orig.)

    Considering the emerging advantages related to da Vinci Xi robotic platform, the aim of this study is to compare for the first time the operative outcomes of this tool to the previous da Vinci Si during transoral robotic surgery (TORS), both performed for squamous cell carcinomas (SCC) of the base of tongue (BOT). Intra- and peri-operative outcomes of eight patients with early stage (T1-T2) of the BOT carcinoma and undergoing TORS by means of the da Vinci Xi robotic platform (Xi-TORS) are compared with the da Vinci Si group ones (Si-TORS). With respect to Si-TORS group, Xi-TORS group demonstrated a significantly shorter overall operative time, console time, and intraoperative blood loss, as well as peri-operative pain intensity and length of mean hospital stays and nasogastric tube positioning. Considering recent advantages offered by surgical robotic techniques, the da Vinci Xi Surgical System preliminary outcomes could suggest its possible future routine implementation in BOT squamous cell carcinoma procedures.

    We report preliminary results obtained from a multi-proxy analysis including paleomagnetic and rock-magnetic studies of two sediment cores of Laguna Carmen (53°40'60" S 68°19'0" W, ~83m asl) in the semiarid steppe in northern Tierra del Fuego island, Southernmost Patagonia, Argentina. Two short cores (115 cm) were sampled using a Livingstone piston corer during the 2011 southern fall. Sediments are massive green clays (115 to 70 cm depth) with irregularly spaced thin sandy strata and lens. Massive yellow clay with thin sandy strata continues up to 30 cm depth; from here up to 10 cm yellow massive clays domain. The topmost 10 cm are mixed yellow and green clays with fine sand. Measurements of intensity and directions of Natural Remanent Magnetization (NRM), magnetic susceptibility, isothermal remanent magnetization, saturation isothermal remanent magnetization (SIRM), back field and anhysteretic remanent magnetization at 100 mT (ARM100mT) were performed and several associated parameters calculated (ARM100mT/k and SIRM/ ARM100mT). Also, as a first estimate of relative magnetic grain-size variations, the median destructive field of the NRM (MDFNRM), was determined. Additionally, we present results of magnetic parameters measured with vibrating sample magnetometer (VSM). The stability of the NRM was analyzed by alternating field demagnetization. The magnetic properties have shown variable values, showing changes in both grain size and concentration of magnetic minerals. It was found that the main carrier of remanence is magnetite with the presence of hematite in very low percentages. This is the first paleomagnetic study performed in lakes located in the northern, semiarid fuegian steppe, where humid-dry cycles have been interpreted all along the Holocene from an aeolian paleosoil sequence (Orgeira et el, 2012). Comparison between paleomagnetic records of Laguna Carmen and results obtained in earlier studies carried out at Laguna Potrok Aike (Gogorza et al., 2012

    The planning of performances in radiological emergencies, with the object of reducing the consequences as much as possible on the population to accidental liberations of radioactive material coming from Nuclear power plant, it has been of main interest in the nuclear community in the world. In Mexico it has not been the exception, since with the setting in march of the Laguna Verde nuclear power plant exists an executive program of planning for emergencies that it outlines the activities to follow trending to mitigate the consequences that are derived of this emergency. As integral part of this program this the External Plan of Radiological Emergency (PERE) that covers the emergencies that could leave the frontiers of the Laguna Verde power plant. In the PERE it settles down the planning, address and control of the preparation activities, response and recovery in emergencies, as well as the organization and coordination of the institutions that participate. The National Institute of Nuclear Research (ININ), like integral part of these institutions in the PERE, has an infrastructure that it allows to participate in the plan in a direct way in the activities of 'Control of the radiological exhibition the response personnel and control of water and foods' and of support way and consultant ship in the activities of 'Monitoring, Classification and decontamination of having evaluated' and 'Specialized medical radiological attention'. At the moment the ININ has a radiological mobile unit and this conditioning a second mobile unit to carry out part of the activities before mentioned; also accounts with 48 properly qualified people that directly intervene in the plan. In order to guarantee an adequate response in the PERE an organization it has been structured like that of the annex as for the personnel, transport, team, procedures and communication system, with the objective always of guaranteeing the security and the population's health in emergency situations in the

  6. Geological setting and paleomagnetism of the Eocene red beds of Laguna Brava Formation (Quebrada Santo Domingo, northwestern Argentina)

    The red bed succession cropping out in the Quebrada Santo Domingo in northwestern Argentina had been for long considered as Upper Triassic-Lower Jurassic in age based on weak radiometric and paleontological evidence. Preliminary paleomagnetic data confirmed the age and opened questions about the nature of fossil footprints with avian features discovered in the section. Recently the stratigraphic scheme was reviewed with the identification of previously unrecognized discontinuities, and a radiometric dating obtained in a tuff, indicated an Eocene age for the Laguna Brava Formation and the fossil bird footprints, much younger than the previously assigned. We present a detailed paleomagnetic study interpreted within a regional tectonic and stratigraphic framework, looking for an explanation for the misinterpretation of the preliminary paleomagnetic data. The characteristic remanent magnetizations pass a tilt test and a reversal test. The main magnetic carrier is interpreted to be low Ti titanomagnetites and to a lesser extent hematite. The characteristic remanent magnetization would be essentially detrital. The obtained paleomagnetic pole (PP) for the Laguna Brava Formation has the following geographic coordinates and statistical parameters: N = 29, Lon. = 184.5° E, Lat. = 75.0° S, A95 = 5.6° and K = 23.7. When this PP is compared with another one with similar age obtained in an undeformed area, a declination anomaly is recognized. This anomaly can be interpreted as Laguna Brava Formation belonging to a structural block that rotated about 16° clockwise along a vertical axis after about 34 Ma. This block rotation is consistent with the regional tectonic framework, and would have caused the fortuitous coincidence of the PP with Early Jurassic poles. According to the interpreted magnetostratigraphic correlation, the Laguna Brava Formation would have been deposited during the Late Eocene with a mean sedimentation rate of about 1.4 cm per thousand years, probably in

    To describe our robot-assisted nephroureterectomy (RNU) technique for benign indications and RNU with en bloc excision of bladder cuff (BCE) and lymphadenectomy (LND) for malignant indications using the da Vinci Si and da Vinci Xi robotic platform, with its pros and cons. The port placement described for Si can be used for standard and S robotic systems. This is the first report in the literature on the use of the da Vinci Xi robotic platform for RNU. After a substantial experience of RNU using different da Vinci robots from the standard to the Si platform in a single-docking fashion for benign and malignant conditions, we started using the newly released da Vinci Xi robot since 2014. The most important differences are in port placement and effective use of the features of da Vinci Xi robot while performing simultaneous upper and lower tract surgery. Patient positioning, port placement, step-by-step technique of single docking RNU-LND-BCE using the da Vinci Si and da Vinci Xi robot are shown in an accompanying video with the goal that centres using either robotic system benefit from the hints and tips. The first segment of video describes RNU-LND-BCE using the da Vinci Si followed by the da Vinci Xi to highlight differences. There was no need for patient repositioning or robot re-docking with the new da Vinci Xi robotic platform. We have experience of using different robotic systems for single docking RNU in 70 cases for benign (15) and malignant (55) conditions. The da Vinci Xi robotic platform helps operating room personnel in its easy movement, allows easier patient side-docking with the help of its boom feature, in addition to easy and swift movements of the robotic arms. The patient clearance feature can be used to avoid collision with the robotic arms or the patient's body. In patients with challenging body habitus and in situations where bladder cuff management is difficult, modifications can be made through reassigning the camera to a different port with

    Microbialites provide some of the oldest direct evidence of life on Earth. They reached their peak during the Proterozoic and declined afterward. Their decline has been attributed to grazing and/or burrowing by metazoans, to changes in ocean chemistry, or to competition with other calcifying organisms. The freshwater microbialites at Laguna Bacalar (Mexico) provide an opportunity to better understand microbialite growth in terms of interaction between grazing organisms versus calcium carb...

  13. Traces of warping subsided tectonic blocks on Miranda, Enceladus, Titan

    sharp difference between uplifted and subsided blocks presents Miranda having very sharp relief range. Subsided areas (coronas) are strongly folded, uplifted areas strongly degassed what was witnessed by numerous craters of various sizes (not all craters are of impact origin!). Coronas on Miranda present subsided segment and sectors. Typical is a very sharp boundary between risen (+) and fallen (-) blocks. On Enceladus the subsided (squeezed) southern pole area is characterized by "tiger stripes" - traces of contraction, young ice deposits and famous ejections of water vapor and ice. The squeezed area expels 'molten" material from interior - compare with periodically active Hawaiian volcano expelling basalts from constantly under contraction Pacific basin interior. As to the subsided Pacific basin, it is antepodean to uplifted deeply cracked and degassing Africa. On Enceladus to contracted south is opposed expanded north where past degassing is witnessed by numerous craters (not all of them are impacts!). Contraction traces are very impressive on subsided Titan's surfaces - methane filled thinly folded huge areas mainly in near equatorial regions (some scientists think that these folds are eolian dunes but they are parallel, not perpendicular to presumed winds and, besides, winds below ˜60 km in Titan's atmosphere are not detected by "Huygens") [1, 2]. This methane rich area of intensive folding is antepodean to the uplifted and mainly composed of water ice region Xanadu cut by numerous tectonically controlled dry "valleys". So, in spite of many varieties of surface features on icy satellites of the outer Solar system a common main tectonic tendency exists: opposition of subsided contracted and uplifted expanded blocks.

  14. Factor XI Deficiency Alters the Cytokine Response and Activation of Contact Proteases during Polymicrobial Sepsis in Mice.

    Directory of Open Access Journals (Sweden)

    Charles E Bane

    Full Text Available Sepsis, a systemic inflammatory response to infection, is often accompanied by abnormalities of blood coagulation. Prior work with a mouse model of sepsis induced by cecal ligation and puncture (CLP suggested that the protease factor XIa contributed to disseminated intravascular coagulation (DIC and to the cytokine response during sepsis. We investigated the importance of factor XI to cytokine and coagulation responses during the first 24 hours after CLP. Compared to wild type littermates, factor XI-deficient (FXI-/- mice had a survival advantage after CLP, with smaller increases in plasma levels of TNF-α and IL-10 and delayed IL-1β and IL-6 responses. Plasma levels of serum amyloid P, an acute phase protein, were increased in wild type mice 24 hours post-CLP, but not in FXI-/- mice, supporting the impression of a reduced inflammatory response in the absence of factor XI. Surprisingly, there was little evidence of DIC in mice of either genotype. Plasma levels of the contact factors factor XII and prekallikrein were reduced in WT mice after CLP, consistent with induction of contact activation. However, factor XII and PK levels were not reduced in FXI-/- animals, indicating factor XI deficiency blunted contact activation. Intravenous infusion of polyphosphate into WT mice also induced changes in factor XII, but had much less effect in FXI deficient mice. In vitro analysis revealed that factor XIa activates factor XII, and that this reaction is enhanced by polyanions such polyphosphate and nucleic acids. These data suggest that factor XI deficiency confers a survival advantage in the CLP sepsis model by altering the cytokine response to infection and blunting activation of the contact (kallikrein-kinin system. The findings support the hypothesis that factor XI functions as a bidirectional interface between contact activation and thrombin generation, allowing the two processes to influence each other.

    Minimal invasive surgery has proven its advantages over open surgeries in the perioperative period. Food and Drug Administration approved da Vinci robot in 2000. The latest version, da Vinci Xi system has a mobile tower-based robot with several modifications to improve the functionality, versatility, and operative ease. None of the centers have reported exclusively on hepatobiliary oncology using the da Vinci Xi system. We report our initial experience. To study the feasibility, advantages, and discuss the operative technique of da Vinci Xi system in hepatobiliary oncology. Data were analyzed retrospectively from a prospectively maintained database from June 2015 to October 2016. Twenty-five patients with suspected or proven hepatobiliary malignancies were operated. Total robotic technique using da Vinci Xi system was used. Demographic details and perioperative outcomes were noted. Of the 25 surgeries, 14 patients had a suspected gallbladder malignancy, 11 patients had primary or metastatic liver tumor. Median age was 53 years. The average duration of surgery was 225 min with a median blood loss 150 ml. The median postoperative stay was 4 days. The median nodal yield for radical cholecystectomy was seven. Five patients required conversion. Two of these developed postoperative morbidity. Robotic surgery for hepatobiliary oncology is feasible and can be performed safely in experienced hands. Increasing experience in this field may equal or even prove advantageous over conventional or laparoscopic approach in future. A cautious approach with judicious patient selection is the key to establishing robotic surgery as a standard surgical approach.

    Physical characterization and chemical analysis of settled dusts collected in Xi'an from November 2007 to December 2008 show that (1) dust deposition rates ranged from 14.6 to 350.4 g m{sup -2} yr{sup -1}. The average deposition rate (76.7 g m{sup -2} yr{sup -1}) ranks the 11th out of 56 dust deposition rates observed throughout the world. The coal-burning power was the major particle source; (2) on average (except site 4), {approx}10% of the settled dusts having size <2.6, {approx}30% having size <10.5, and >70% having size <30 {mu}m; (3) the concentrations for 20 out of 27 elements analyzed were upto 18 times higher than their soil background values in China. With such high deposition rates of dusts that contain elevated levels of toxic elements, actions should be taken to reduce emission and studies are needed to assess the potential impacts of settled particles on surface ecosystem, water resource, and human health in the area. - Research highlights: High atmospheric dust deposition rate in Xi'an, Shaanxi, China. Coal-burning power plan being a major source of particulate matter in Xi'an area. High levels of toxic elements in the settled dusts. Enrichment of heavy metals (e.g., Pb, Ni, Cu) in fine particles. - Atmospheric dust deposition rate is high and the levels of toxic elements associated with the settled dusts are elevated in Xi'an, Shaanxi, China.

    In this work the main results of the simulation of overpressure events are presented using a model of the nuclear power plant of Laguna Verde developed for the RELAP/SCDAPSIM code. As starting point we have the conformation of a Laguna Verde model that represents a stationary state to similar conditions to the operation of the power station with Extended Power Up rate (EPU). The transitory of simulated pressure are compared with those documented in the Final Safety Analysis Report of Laguna Verde (FSAR). The results of the turbine shot transitory with and without by-pass of the main turbine are showed, and the event of closes of all the valves of main vapor isolation. A preliminary simulation was made and with base in the results some adjustments were made for the operation with EPU, taking into account the Operation Technical Specifications of the power station. The results of the final simulations were compared and analyzed with the content in the FSAR. The response of the power station to the transitory, reflected in the model for RELAP, was satisfactory. Finally, comments about the improvement of the model are included, for example, the response time of the protection and mitigation systems of the power station. (Author)

    The present work is a continuation of the task: Modeling of the vapor cycle of Laguna Verde with the PEPSE code to conditions of thermal power licensed at present (2027 MWt) in which the modeling of the vapor cycle of the nuclear power plant of Laguna Verde was realized with PEPSE code (Performance Evaluation of Power System Efficiencies). Once reached the conditions of nominal operation of extended power increase, operating both units to 2371 MWt; after the tests phase of starting-up and operation is necessary to carry out a verification of the proposed design of the vapor cycle for the new operation conditions. All this, having in consideration that the vapor cycle designer only knows the detail of the prospective performance of the main turbine, for all the other components (for example pumps, heat inter changers, valves, reactor, humidity separators and re-heaters, condensers, etc.) makes generic suppositions based on engineering judgment. This way carries out the calculations of thermal balance to determine the guaranteed gross power. The purpose of the present work is to comment the detail of the validation carried out of the specific thermal balance (thermal kit) of the nuclear power plant, making use of the design characteristics of the different components that conform the vapor cycle.

    Full Text Available The places by the sea, as spaces of tourism and second homes, suffer the impacts from the activity. The local population attitude, seeing these places as bonuses or otherwise, as a burden, contributes to the viability of tourism in the locality. This article aims to present a research, methodologically related to attitude construct of social psychology, conducted in Laguna, Santa Catarina, Brazil to evaluate the relationship between the community and the different impacts caused by tourism,. Data collection, using an instrument originally proposed and validated by Molero and Cuadrado (2006, allowed the analysis to forward the position of residents on the effects of tourism in the place, evaluating eight impacts factors: environmental; delinquency; everyday life; perceived importance of tourism; public services and infrastructure; intercultural; employment; and values. The results indicate that most impacts are positive on younger residents, and in the environmental, crime and social values the impact is indifferent.

    The aim of this study was to compare the short-term outcomes of robotic rectal resection with total mesorectal excision (TME) for rectal cancer, with the use of the new da Vinci Xi® (Xi-RobTME group) and the da Vinci Si® (Si-RobTME group). Ten patients with histologically confirmed rectal cancer underwent robot-assisted TME with the use of the new da Vinci Xi. The outcomes of Xi-RobTME group were compared with a Si-RobTME group selected using a case-matched methodology. Overall operative times and mean hospital stays were shorter in the Xi-RobTME group. Surgeries were fully robotic with a complete take-down of the splenic flexure in all Xi-RobTME cases, while only four cases of the Si-RobTME group were fully robotic, with two cases of complete take-down of the splenic flexure. The new da Vinci Xi could offer some advantages with respect to the da Vinci Si in rectal resection for cancer. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    The reason is to give to know to the nuclear community in Mexico the good results that it located in the 2006 to the Laguna Verde Nucleo electric Central in the classification of the World Association of Nuclear Operators (WANO) like one of the best in the worldwide scale, and their Strategic Plan 2007-2011 like an opportunity to continue improving the Quality, the Competitiveness and the Excellency in their Generating Units. It stands out that the fuel reloads are carried out in systemic form in less than 30 days, and also other achievements like it is the certificate granted by PROFEPA of Clean Industry, the renovation of the Certifications of the ISO-9001 and the ISO-14001, as well as the accredit of the Laboratories, and they will give data of the project of the increment of power that their power rose in 15%. For those results in the Strategic Planning 2007-2011 are pointed out that the Laguna Verde Central is a highly viable option in Mexico, when continuing with reloads that will allow a capacity factor up of 90%, and the other concepts that will give the obtaining of the qualification level 1 of WANO in this strategic period. Finally I will conclude with the good news for the Nuclear Industry in Mexico that published the Reforma newspaper at November 01, 2006: 'To the president of Mexico, Felipe Calderon, interests him to impel during his command the alternating energy sources to the hydrocarbons, known it is that the hydrocarbons (petroleum, coal or natural gas) they are finite, while the appetite of the world for the energy is infinite. As you they know, Mexico possesses a nuclear plant that generates energy starting from enriched uranium: the famous Laguna Verde Thermonuclear Central. He declared that Mexico can and it should advance for the one on the way to the energy generation for the nuclear road.' (Author)0.

    Full Text Available Hay un escaso conocimiento de las aves playeras en los humedales costeros de Jalisco, y en particular en la laguna Barra de Navidad. El presente trabajo contribuye al conocimiento de este grupo de aves y describe su distribución temporal y espacial en la laguna Barra de Navidad durante tres temporadas no reproductivas (1999-2000, 2006-2007 y 2008-2009. Se realizaron censos mensuales de noviembre-abril en las tres temporadas con el fin de registrar todas las especies de aves playeras. Se identificaron 19 especies (tres residentes y 16 visitantes de invierno, de las cuales Charadrius wilsonia, Limosa fedoa y Tringa semipalmata presentaron la mayor abundancia. Doce especies son consideradas como prioritarias en la “Estrategia para la Conservación y Manejo de las Aves Playeras y su Hábitat en México”. El mayor número de especies fue registrado en noviembre, diciembre y marzo en la primera y tercera temporada. El mayor número de individuos fue registrado alimentándose en marea baja, principalmente en diciembre, enero y febrero de la primera y tercera temporada. En marea baja hubo un mayor número de especies e individuos alimentándose en la zona C. Esta zona se caracterizó por tener sustratos lodosos expuestos durante marea baja y que fueron aprovechados por las aves para alimentarse. La laguna Barra de Navidad proporcionó hábitats de alimentación y descanso para las aves residentes y migratorias. Sin embargo, estos hábitats se ven amenazados por las actividades humanas realizadas dentro de la laguna, que sin duda tendrán consecuencias negativas para la distribución y abundancia de las aves playeras.

    High-altitude mountain lakes remain understudied, mostly because of their relative inaccessibility. Laguna de Guatavita, a small, equatorial, high-altitude crater lake in the Eastern Range of the Colombian Andes, was once of high cultural importance to pre-Columban inhabitants, the original location of the legendary El Dorado. We investigated the factors regulating the primary production in Laguna de Guatavita (4degrees58'50" N - 73degrees46'43" W, alt. 2 935m.a.s.l., area: 0.11km2, maximum depth: 30m), during a series of three intensive field campaigns, which were conducted over a year-long period in 2003-2004. In each, standard profiles of temperature, oxygen concentration and light intensity were determined on each of 16-18 consecutive days. Samples were collected and analysed for chlorophyll and for biologically-significant solutes in GF/F-filtered water (NH4+, NO3(-), NO2(-); soluble reactive phosphorus). Primary production was also determined, by oxygen generation, on each day of the campaign. Our results showed that the productive potential of the lake was typically modest (campaign averages of 45-90mg C/m2.h) but that many of the regulating factors were not those anticipated intuitively. The lake is demonstrably meromictic, reminiscent ofkarstic dolines in higher latitudes, its stratification being maintained by solute- concentration gradients. Light penetration is poor, attributable to the turbidity owing to fine calcite and other particulates in suspension. Net primary production in the mixolimnion of Laguna de Guavita is sensitive to day-to-day variations in solar irradiance at the surface. However, deficiencies in nutrient availability, especially nitrogen, also constrain the capacity of the lake to support a phytoplankton. We deduced that Laguna de Guatavita is something of a limnological enigma, atypical of the common anticipation of a "mountain lake". While doubtlessly not unique, comparable descriptions of similar sites elsewhere are sufficiently

    Tilapia, Oreochromis niloticus, one of the most important fish species in Philippine aquaculture, is grown abundantly in Laguna de Bay. A preliminary study was conducted to determine the levels of accumulated mercury (Hg), cadmium (Cd) and lead (Pb) in the muscle tissue of this fresh water fish collected from February (wet season) to March (dry season) 2008 in the southern part of Laguna de Bay. Heavy metal analyses using atomic absorption spectrophotometer (AAS) showed a higher concentration of Hg and Cd during the wet season than in the dry season. However, analysis of variance revealed significant seasonal variation on only in Cd (P=0.0253). Lead, on the other hand, was not detected in the fish samples. The mean concentration set by FAO but the mean level of Cd (0.161 ppm) was almost equal to the limit given for fish. This could represent a significant health risk to the consuming public. (author)

    Cartilage extracellular matrix (ECM) has been used for promoting tissue engineering. However, the exact effects of ECM on chondrogenesis and the acting mechanisms are not well understood. In this study, we investigated the chondrogenic effects of cartilage ECM on human mesenchymal stem cells (MSCs) and identified the contributing molecular components. To this end, a preparation of articular cartilage ECM was supplemented to pellets of chondrogenically differentiating MSCs, pellets of human chondrocytes, and bovine articular cartilage explants to evaluate the effects on cell proliferation and the production of cartilaginous matrix. Selective enzymatic digestion and screening of ECM components were conducted to identify matrix molecules with chondrogenic properties. Cartilage ECM promoted MSC proliferation, production of cartilaginous matrix, and maturity of chondrogenic differentiation, and inhibited the hypertrophic differentiation of MSC-derived chondrocytes. Selective digestion of ECM components revealed a contributory role of collagens in promoting chondrogenesis. The screening of various collagen subtypes revealed strong chondrogenic effect of collagen type XI. Finally, collagen XI was found to promote production and inhibit degradation of cartilage matrix in human articular chondrocyte pellets and bovine articular cartilage explants. Our results indicate that cartilage ECM promotes chondrogenesis and inhibits hypertrophic differentiation in MSCs. Collagen type XI is the ECM component that has the strongest effects on enhancing the production and inhibiting the degradation of cartilage matrix. Copyright © 2018 Elsevier Ltd.

    This paper describes lake sediment spheroidal carbonaceous particle (SCP) profiles from Laguna Chica San Pedro, located in the Biobio Region, Chile (36 o 51' S, 73 o 05' W). The earliest presence of SCPs was found at 16 cm depth, corresponding to the 1915-1937 period, at the very onset of industrial activities in the study area. No SCPs were found at lower depths. SCP concentrations in Laguna Chica San Pedro lake sediments were directly related to local industrial activities. Moreover, no SCPs were found in Galletue lake (38 o 41' S, 71 o 17.5' W), a pristine high mountain water body used here as a reference site, suggesting that contribution from long distance atmospheric transport could be neglected, unlike published data from remote Northern Hemisphere lakes. These results are the first SCP sediment profiles from Chile, showing a direct relationship with fossil fuel consumption in the region. Cores were dated using the 21 Pb technique. - The lake sediment record of SCPs shows the record of fossil-fuel derived pollution in Central Chile

    Reactivity initiated accidents (RIA) and design basis transients are one of the most important aspects related to nuclear power reactor safety. These events are re-evaluated whenever core alterations (modifications) are made as part of the nuclear safety analysis performed to a new design. These modifications usually include, but are not limited to, power upgrades, longer cycles, new fuel assembly and control rod designs, etc. The results obtained are compared with pre-established bounding analysis values to see if the new core design fulfills the requirements of safety constraints imposed on the design. The control rod drop accident (CRDA) is the design basis transient for the reactivity events of BWR technology. The CRDA is a very localized event depending on the control rod insertion position and the fuel assemblies surrounding the control rod falling from the core. A numerical benchmark was developed based on the CRDA RIA design basis accident to further asses the performance of coupled 3D neutron kinetics/thermal-hydraulics codes. The CRDA in a BWR is a mostly neutronic driven event. This benchmark is based on a real operating nuclear power plant - unit 1 of the Laguna Verde (LV1) nuclear power plant (NPP). The definition of the benchmark is presented briefly together with the benchmark specifications. Some of the cross-sections were modified in order to make the maximum control rod worth greater than one dollar. The transient is initiated at steady-state by dropping the control rod with maximum worth at full speed. The 'Laguna Verde' (LV1) BWR CRDA transient benchmark is calculated using two coupled codes: TRAC-BF1/NEM and TRAC-BF1/ENTREE. Neutron kinetics and thermal hydraulics models were developed for both codes. Comparison of the obtained results is presented along with some discussion of the sensitivity of results to some modeling assumptions

    A model for the Radiation Monitoring System of the Laguna Verde Boiling Water Reactor training simulator is presented. This model comprises enough definitions to assure interactions with the processes related, directly or indirectly, with the transport of radioisotopes. It is capable of following a dynamic behavior of the plant so an operator could be trained to become aware of nuclear radiation hazards. The model is composed of three parts: the electronics for the Process and Area Radiation Monitoring System; a lumped parameter transport model for the most representative radioisotopes; and the interactions with the modeled processes as well as with process not being simulated. The first part represents the radiation monitor controls in the vertical board panels of the nuclear station. The second part allows the carrying of nuclear isotopes between processes. The third part defines the way that the process interacts with the electronics at the point of release to environment or the point of detection. Each part of the model has been tested individually, and the transport model has been incorporated as a part of each process required to simulate nuclear radiation. The model parameters has been calculated using typical BWR nuclear radiation data, and Laguna Verde heat balance data at 100% design power. However, tunning will be necessary once the Simulator is integrated and tested. The tunning allows each detecting channel to behave as expected

  17. Coronal Diagnostics of Intermediate Activity Star XI Boo A

    2005-01-01

    The analysis of Xi Boo A proved difficult to adapt to our line-by-line approach because of the strong wings of the RGS instrumental profile, as has been detailed in earlier reports. While progress was also delayed because of problems in using SAS v4, we succeeded in the past year or so to bring the analysis to conclusion. Abundances have been derived using both EPIC and RGS data, confirming earlier EUVE findings of a mild solar-like FIP effect, though with some evidence of a turn-up in abundances of elements with higher FIP. Plasma densities appear normal for a moderately active stellar corona. Xi Boo A nicely bridges the gap between the very active stars and stars like the Sun, and it indeed does appear that these are the stars in which the solar-like FIP effects begins to change to the "inverse FIP" type of effect seen in the very active stars. Probing this divide was the main goal of the proposal. These results are in the process of being prepared for publication, though we have not decided the target journal as yet.

    Long-term exposure to high levels of fine particulate matter (PM2.5) is found to be associated with adverse effects on human health, ecological environment and climate change. Identification the major source regions of fine particulate matter are essential to proposing proper joint prevention and control strategies for heavy haze mitigation. In this work, the Comprehensive Air Quality Model with extensions (CAMx) together with the Particulate Source Apportionment Technology (PSAT) and the Weather Research and Forecast Model (WRF), have been applied to analyze the major source regions of PM2.5 in Xi'an during the heavy haze episodes in winter (29, December, 2016 - 5 January 2017), and the framework of the model system is shown in Fig. 1. Firstly, according to the model evaluation of the daily PM2.5 concentrations for the two months, the model has well performance, and the fraction of predictions within a factor of 2 of the observations (FAC2) is 84%, while the correlation coefficient (R) is 0.80 in Xi'an. By using the PSAT in CAMx model, a detailed source region contribution matrix is derived for all points within the Xi'an region and its six surrounding areas, and long-range regional transport. The results show that the local emission in Xi'an is the mainly sources at downtown area, which contributing 72.9% as shown in Fig.2, and the contribution rate of transportations between adjacent areas depends on wind direction. Meanwhile, three different suburban areas selected for detailed analysis in fine particles sources. Comparing to downtown area, the sources of suburban areas are more multiply, and the transportations make the contribution 40%-82%. In the suburban areas, regional inflows play an important role in the fine particles concentrations, indicating a strong need for regional joint emission control efforts. The results enhance the quantitative understanding of the PM2.5 source regions and provide a basis for policymaking to advance the control of pollution

    Since the Spanish Period (1600s), natural hot spring waters have been harnessed for balneological purposes in the municipalities of Calamba and Los Banos, Laguna, south of Metro Manila. There are at more than a hundred hot spring resorts in Brgy. Pansol, Calamba and Tadlac, Los Banos. These two areas are found at the northern flanks of Mt. Makiling facing Laguna de Bay. This study aims to provide some insights on the physical and chemical characteristics of hot spring resorts and the possible impact on the lake water quality resulting from the disposal of used water. Initial ocular survey of the resorts showed that temperature of the pool water ranges from ambient (>300C) to as high as 500C with an average pool size of 80m3. Water samples were collected from a natural hot spring and pumped well in Los Banos and another pumped well in Pansol to determine the chemistry. The field pH ranges from 6.65 to 6.87 (Pansol springs). Cation analysis revealed that the thermal waters belonged to the Na-K-Cl-HCO3 type with some trace amount of heavy metals. Methods for waste water disposal are either by direct discharge down the drain of the pool or by discharge in the public road canal. Both methods will dump the waste water directly into Laguna de Bay. Taking in consideration the large volume of waste water used especially during the peak season, the effect on the lake water quality would be significant. It is therefore imperative for the environmental authorities in Laguna to regulate and monitor the chemistry of discharges from the pool to protect both the lake water as well as groundwater quality.

    In a partnership with GSE Systems, TECNATOM is developing a full scope training simulator for Laguna Verde Unit 2 (LV2). The simulator design is based upon the current 'state-of-the art technology' regarding the simulation platform, instructor station, visualization tools, advanced thermalhydraulics and neutronics models, I/O systems and automated model building technology. When completed, LV2 simulator will achieve a remarkable level of modeling fidelity by using TECNATOM's TRAC-RT advanced thermalhydraulic code for the reactor coolant and main steam systems, and NEMO neutronic model for the reactor core calculations. These models have been utilized up to date for the development or upgrading of nine NPP simulators in Spain and abroad, with more than 8000 hours of training sessions, and have developed an excellent reputation for its robustness and high fidelity.

    Robotic rectal resection with da Vinci Si has some technical limitations, which could be overcome by the new da Vinci Xi. We compare short-term surgical and functional outcomes following robotic rectal resection with total mesorectal excision for cancer, with the da Vinci Xi (Xi-RobTME group) and the da Vinci Si (Si-RobTME group). The first consecutive 30 Xi-RobTME were compared with a Si-RobTME control group of 30 patients, selected using a one-to-one case-matched methodology from our prospectively collected Institutional database, comprising all cases performed between April 2010 and September 2016 by a single surgeon. Perioperative outcomes were compared. The impact of minimally invasive TME on autonomic function and quality of life was analyzed with specific questionnaires. The docking and overall operative time were shorter in the Xi-RobTME group (p  25 kg/m 2 was necessary in ten patients (45 vs. 0%, p da Vinci Xi seem to be mainly associated with a shorter docking and operative time and with superior ability to perform a fully-robotic approach. Clinical and functional outcomes seem not to be improved, with the introduction of the new Xi platform.

    The adoption of robot-assisted laparoscopic colorectal surgery has been hampered by issues with docking, operative duration, technical difficulties in multi-quadrant access, and cost. The da Vinci® Xi has been designed to overcome some of these limitations. We describe our experience with the system and offer technical insights to its application in left-sided colorectal procedures. Our initial series of left-sided robotic colorectal procedures was evaluated. Patient demographics and operative outcomes were recorded prospectively using a predefined database. Between March 2015 and April 2016, 54 cases of robot-assisted laparoscopic left-sided colorectal procedures were successfully completed with no cases of conversion. The majority were low anterior resections for colorectal malignancies. Using the da Vinci® Xi Surgical System, multi-quadrant surgery involving dissection from the splenic flexure to the pelvis was possible without redocking. The da Vinci® Xi simplifies the docking procedure and makes single-docking feasible for multi-quadrant left-sided colorectal procedures. Copyright © 2016 John Wiley & Sons, Ltd.

    A critical technical element of nuclear power plant license renewal in the United States is the demonstration that the effects of aging do not compromise the intended safety function(s) of a system, structure, or component during the extended term of operation. The demonstration may take either of two forms. First, it can be shown that the design basis for the system, structure, or component is sufficiently robust that the aging effects have been insignificant through the current license term, and will continue to be insignificant through the extended term. Alternatively, it can be shown that, while the aging effects may be potentially significant, those effects can be managed and functionality maintained by defined programmatic activities during the extended term of operation. The first of the two approaches is generally provided by the construction basis, such as construction in accordance with the ASME Code Section III and other consensus codes and standards. The second of the two approaches is often provided by periodic inservice inspection and testing, in accordance with the ASME Code Section XI. The purpose of the ASME Section XI inspections and tests is to assure that systems, components, and structures are fit for continued service until the next scheduled inspection or test. The purpose of this paper is to document the effectiveness of the current ASME Code Section XI visual examination procedures in detecting the effects of aging for systems, structures, and components that are tolerant of mature cracks.

    Palinological analysis of 16 samples from the well ELS-1 in Laguna Salada, allows recognition of environmental changes in the drilled section. No age assignments are made because of the low diversity of the palinological assemblages recovered. These assemblages include species with ages from Campanian to Pleistocene. The cretaceous forms indicate reworking from a cretaceous unit within the Colorado river drainage basin. Integration of the palinological, lithological and well log data permit the recognition of three main cycles. The lower one is regressive and contains mostly fluvial to deltaic shallow marine sediments. The intermediate cycle is transgressive-regressive, contains the maximum flooding surface of the section studied and represents an interval of strong tectonic movements with well developed marine transgressions. The upper cycle is also transgressive-regressive, with lagoon and distal alluvial fan deposits. [Spanish] El analisis palinologico de 16 muestras del pozo: ELS-1 del proyecto geotermico de Laguna Salada permite reconocer cambios ambientales en la seccion perforada. La baja diversidad de los conjuntos palinologicos recuperados impide determinar edades. Se observan especies indicadoras de edades desde Campaniese hasta Pleistoceno. Las formas cretacicas indican retrabajo de alguna unidad cretacica dentro de la cuenca del rio Colorado. La integracion de datos palinologicos, litologicos y de registros geofisicos, permite reconocer tres ciclos principales. El ciclo inferior es regresivo y contiene principalmente sedimentos fluviales a deltaicos de niveles bajos del mar. El ciclo intermedio, es transgresivo-regresivo, contiene la superficie de inundacion maxima de toda la seccion estudiada y representa una etapa de movimientos tectonicos fuertes con transgresiones marinas bien desarrolladas. El ciclo superior tambien es transgresivo-regresivo, con depositos lagunares y de abanicos aluviales distales.

    Transoral thyroid surgery allows the surgeon to conceal incisions within the oral cavity without significantly increasing the amount of required dissection. TORT provides an ideal scarless, midline access to the thyroid gland and bilateral central neck compartments. This approach, however, presents multiple technical challenges. Herein, we present our experience using the latest generation robotic surgical system to accomplish transoral robotic thyroidectomy (TORT). In two human cadavers, the da Vinci Xi surgical system (Intuitive Surgical, Sunnyvale, CA, USA) was used to complete TORT. Total thyroidectomy and bilateral central neck dissection was successfully completed in both cadavers. The da Vinci Xi platform offered several technologic advantages over previous robotic generations including overhead docking, narrower arms, and improved range of motion allowing for improved execution of previously described TORT techniques.

    The project of extended increase of power responds to a necessity of electrical energy in the country, increasing the thermal exit of the reactors of the nuclear power plant of Laguna Verde of 2027 MWt to 2317 MWt. In order to support this transition, changes will make in the configuration of the reactor core and in the operation strategies of the cycle, also they will take initiatives to optimize the economy in fuel cycle. At present in both reactors of the nuclear plant of Laguna Verde fuel GE12 is used. The fuel GE14 presents displays with respect to the GE12, some improvements in the mechanical design and consequently in its performance generally. Between these improvements we can mention: 1. Spacers of high performance. 2. Shielding with barrier. 3. Filter for sweepings d ebris a nd 4. Fuel rods of minor partial length. The management of nuclear power plants has decided to introduce the use of fuel GE14 in Laguna Verde in the reload 14 for Unit 1 and of the reload 10 for Unit 2. The process of new introduction fuel GE14 consists of two stages, first consists on subjecting the one new design of fuel to the regulator organism in the USA: Nuclear Regulatory Commission, in Mexico the design must be analyzed and authorized by the National Commission of Nuclear Safety and Safeguards, for its approval of generic form, by means of the demonstration of the fulfillment with the amendment 22 of GESTAR II, the second stage includes the specific analyses of plant to justify the use of the new fuel design in a reload core. The nuclear plant of Laguna Verde would use some of the results of the security analyses that have been realized for the project of extended increase of power with fuel GE14, to document the specific analyses of plant with the new fuel design. The result of the analyses indicates that the reload lots are increased of 116-120 assemblies in present conditions (2027 MWt) to 140-148 assemblies in conditions of extended increase of power (2317 MWt).

    Since the revelation of the narrow resonance at 2220 MeV in the K anti K final states of the radiative decay J/Psi-deltaX at SLAC, much theoretical and experimental effort has been devoted to the understanding of this unusual object. Theoretical explanations range from the conventional to the exotic. The experimental evidence, however, rests solely on one experiment and is not of sufficient quality to distinguish among the intriguing possibilities. We describe an experiment which would be ideal to measure precisely the properties of the xi, including its mass, width, and angular momentum

  15. Field reconnaissance of the effects of the earthquake of April 13, 1973, near Laguna de Arenal, Costa Rica

    Plafker, George

    1973-01-01

    At about 3:34 a.m. on April 13, 1973, a moderate-sized, but widely-felt, earthquake caused extensive damage with loss of 23 lives in a rural area of about 150 km2 centered just south of Laguna de Arenal in northwestern Costa Rica (fig. 1). This report summarizes the results of the writer's reconnaissance investigation of the area that was affected by the earthquake of April 13, 1973. A 4-day field study of the meizoseismal area was carried out during the period from April 28 through May 1 under the auspices of the U.S. Geological Survey. The primary objective of this study was to evaluate geologic factors that contributed to the damage and loss of life. The earthquake was also of special interest because of the possibility that it was accompanied by surface faulting comparable to that which occurred at Managua, Nicaragua, during the disastrous earthquake of December 23, 1972 (Brown, Ward, and Plafker, 1973). Such earthquake-related surface faulting can provide scientifically valuable information on active tectonic processes at shallow depths within the Middle America arc. Also, identification of active faults in this area is of considerable practical importance because of the planned construction of a major hydroelectrical facility within the meizoseismal area by the Instituto Costarricense de Electricidad (I.C.E.). The project would involve creation of a storage reservoir within the Laguna de Arenal basin and part of the Río Arenal valley with a 75 m-high earthfill dam across Río Arenal at a point about 10 km east of the outlet of Laguna de Arenal.

  16. Carbonate Formation And Diagenesis In Pastos Grandes Laguna (Bolivia): Modern Analog For The South Atlantic Cretaceous Presalt Travertinoid Deposits

    The Cretaceous Presalt travertinoid deposits of the South Atlantic are usually considered as "strange deposits" having poor equivalents in modern environments. Pastos Grandes Laguna, which is located in a 2.9 Ma caldera on the andean-bolivian Altiplano (at 4450 m), is intersected by active faults with hydrothermal fluids and presents a spherulitic plateform with similar sedimentological facies to the Presalt: halite and bedded evaporites, shrub-shaped calcites, ooids, pisolites and various stromatolites. Pastos Grandes Laguna is certainly one of the best modern analog of the Presalt for investigating the on going processes of carbonate deposition and diagenesis and the influence of biology. During two expeditions, we recovered samples of gas, water and microbial mats from the hydrothermal sources to the evaporating zones on the spherulitic plateform. These samples are being analyzed to determine 1) the influence of the gases emitted at the hydrothermal sources (chemical and isotopic composition) on the chemistry of the Laguna and the mineralogy of its sediments and 2) the role of ecosystems that develop in this environment on carbonate formation. Preliminary results on gas composition, corrected for the atmospheric contribution, indicates a magmatic source of CO2 partly mantellic associated with a small crustal contribution. Other initial results have so far indicated that CO2 gas emissions, evaporation, as well as photosynthesis and respiration play a role on water chemistry and carbonate precipitation. This study will contribute to the overall understanding of the role of organisms in sedimentation and the predictive diagenetic evolution of hydrothermal and lacustrine deposits.

    Eggs from four aquatic bird species nesting in the Lower Laguna Madre, Texas, were collected to determine differences and similarities in the accumulation of congener-specific polychlorinated biphenyls (PCBs) and to evaluate PCB impacts on reproduction. Because of the different toxicities of PCB congeners, it is important to know which congeners contribute most to total PCBs. The predominant PCB congeners were 153, 138, 180, 110, 118, 187, and 92. Collectively, congeners 153, 138, and 180 accounted for 26 to 42% of total PCBs. Congener 153 was the most abundant in Caspian terns (Sterna caspia) and great blue herons (Ardea herodias) and congener 138 was the most abundant in snowy egrets (Egretta thula) and tricolored herons (Egretta tricolor). Principal component analysis indicated a predominance of higher chlorinated biphenyls in Caspian terns and great blue herons and lower chlorinated biphenyls in tricolored herons. Snowy egrets had a predominance of pentachlorobiphenyls. These results suggest that there are differences in PCB congener patterns in closely related species and that these differences are more likely associated with the species' diet rather than metabolism. Total PCBs were significantly greater (p birds from the Lower Laguna Madre were below concentrations known to affect bird reproduction.

    The present work is a continuation of the task: Modeling of the vapor cycle of Laguna Verde with the PEPSE code to conditions of thermal power licensed at present (2027 MWt) in which the modeling of the vapor cycle of the nuclear power plant of Laguna Verde was realized with PEPSE code (Performance Evaluation of Power System Efficiencies). Once reached the conditions of nominal operation of extended power increase, operating both units to 2371 MWt; after the tests phase of starting-up and operation is necessary to carry out a verification of the proposed design of the vapor cycle for the new operation conditions. All this, having in consideration that the vapor cycle designer only knows the detail of the prospective performance of the main turbine, for all the other components (for example pumps, heat inter changers, valves, reactor, humidity separators and re-heaters, condensers, etc.) makes generic suppositions based on engineering judgment. This way carries out the calculations of thermal balance to determine the guaranteed gross power. The purpose of the present work is to comment the detail of the validation carried out of the specific thermal balance (thermal kit) of the nuclear power plant, making use of the design characteristics of the different components that conform the vapor cycle.

    The reason is to give to know to the nuclear community in Mexico the good results that it located in the 2006 to the Laguna Verde Nucleo electric Central in the classification of the World Association of Nuclear Operators (WANO) like one of the best in the worldwide scale, and their Strategic Plan 2007-2011 like an opportunity to continue improving the Quality, the Competitiveness and the Excellency in their Generating Units. It stands out that the fuel reloads are carried out in systemic form in less than 30 days, and also other achievements like it is the certificate granted by PROFEPA of Clean Industry, the renovation of the Certifications of the ISO-9001 and the ISO-14001, as well as the accredit of the Laboratories, and they will give data of the project of the increment of power that their power rose in 15%. For those results in the Strategic Planning 2007-2011 are pointed out that the Laguna Verde Central is a highly viable option in Mexico, when continuing with reloads that will allow a capacity factor up of 90%, and the other concepts that will give the obtaining of the qualification level 1 of WANO in this strategic period. Finally I will conclude with the good news for the Nuclear Industry in Mexico that published the Reforma newspaper at November 01, 2006: 'To the president of Mexico, Felipe Calderon, interests him to impel during his command the alternating energy sources to the hydrocarbons, known it is that the hydrocarbons (petroleum, coal or natural gas) they are finite, while the appetite of the world for the energy is infinite. As you they know, Mexico possesses a nuclear plant that generates energy starting from enriched uranium: the famous Laguna Verde Thermonuclear Central. He declared that Mexico can and it should advance for the one on the way to the energy generation for the nuclear road.' (Author)

    The planning of performances in radiological emergencies, with the object of reducing the consequences as much as possible on the population to accidental liberations of radioactive material coming from Nuclear power plant, it has been of main interest in the nuclear community in the world. In Mexico it has not been the exception, since with the setting in march of the Laguna Verde nuclear power plant exists an executive program of planning for emergencies that it outlines the activities to follow trending to mitigate the consequences that are derived of this emergency. As integral part of this program this the External Plan of Radiological Emergency (PERE) that covers the emergencies that could leave the frontiers of the Laguna Verde power plant. In the PERE it settles down the planning, address and control of the preparation activities, response and recovery in emergencies, as well as the organization and coordination of the institutions that participate. The National Institute of Nuclear Research (ININ), like integral part of these institutions in the PERE, has an infrastructure that it allows to participate in the plan in a direct way in the activities of 'Control of the radiological exhibition the response personnel and control of water and foods' and of support way and consultant ship in the activities of 'Monitoring, Classification and decontamination of having evaluated' and 'Specialized medical radiological attention'. At the moment the ININ has a radiological mobile unit and this conditioning a second mobile unit to carry out part of the activities before mentioned; also accounts with 48 properly qualified people that directly intervene in the plan. In order to guarantee an adequate response in the PERE an organization it has been structured like that of the annex as for the personnel, transport, team, procedures and communication system, with the objective always of guaranteeing the security and the population's health in emergency situations in the

    The high field fluxgate magnetometer experiment flown aboard the Pioneer XI spacecraft is described. This extremely simple instrument was used to extend the spacecraft's upper-limit measurement capability by approximately an order of magnitude (from 0.14 mT to 1.00 mT) with minimum power and volume requirements. This magnetometer was designed to complement the low-field measurements provided by a helium vector magnetometer and utilizes magnetic ring core sensors with biaxial orthogonal sense coils. The instrument is a single-range, triaxial-fluxgate magnetometer capable of measuring fields of up to 1 mT along each orthogonal axis, with a maximum resolution of 1 microT.

  12. Design, development and production of the TNF-XI new powder package

    International Nuclear Information System (INIS)

    Naigeon, P.; Brut, S.; Fujiwara, T.; Cohen, M.E.

    2004-01-01

    The TNF-XI was jointly developed by COGEMA LOGISTICS of France and Nuclear Fuel Industries, Ltd. (NFI) of Japan. The design and development of this package were started in 2000 and it was first used in 2003. The package design was based on the COGEMA LOGISTICS TN trademark UO2 package, which is cylindrical. To optimize the use of space and to facilitate operations, the TNF-XI incorporates four cavities. Each cavity is similar to one TN trademark U02. The overall shape of the package is approximately a one-meter cube, which allows it to be easily arranged and stacked in a transport container. It has a total weight of nearly 1 metric ton when loaded with 300 kg of uraniferous oxide material. The powder (or pellets) is placed inside NFI pails, and three pails are placed inside each cavity. The test results and analyses were documented in the French, Japanese, and United States 'Safety Analysis Reports' in order to get approvals in these countries. Additionally, the French license was validated in other countries. The 'Safety Analysis Reports' were prepared by COGEMA LOGISTICS in France, NFI in Japan and PACKAGING TECHNOLOGY, Inc. in the USA. In order to transform the TNF-XI design into a fleet of 800 packagings, a successful mass production process had to be developed and put into place by COGEMA LOGISTICS and the fabricator MECAGEST. Adopting mass production methods was challenging - not only because of the large quantity of packages, but also because of the rate of production (50 units per month minimum), quality requirements and the need to keep low packaging costs. This resulted in a significant challenge for mass producing the packaging: what was needed was a robust, efficient, and well-organized process. During the development of the manufacturing process, we also worked on shortening the learning curve

    In this work we studied elemental distributions of trace elements, dissolved oxygen and microbiological allotment (total plate count, Coliform, and E. coli) in sediment and surface water from 3 sites in Laguna de Bay. The measured parameters were associated with the quality of the water and to anthropogenic and geogenic processes taking place in the lake. In all cases sediment samples were collected and analyzed for elemental composition using an X-ray fluorescence technique. Water samples were collected and analyzed for nitrate, chloride, and sulfate ions using selective electrodes. Bicarbonate ions in the lake water were determined by titration. The microbial load (total plate count, total coliform and E,. Coli) were determined using Simplate. Field parameters such as pH and conductivity were likewise measured. Preliminary assumptions suggest that proximity to anthropogenic sources has substantially contributed to the combined loads of major ions pollution in the lake. Laguna de Bay is classified as Class C (DENR Administrative Order No. 34). For all the sites, the conductivity of the water were considerably elevated, which ranged from 929 to 933 uS/cm; Site 1 water exceeded the permissible range for pH for Class C water which is 6.5 to 8.5 for the support and rearing of fish. None of the lake waters exceeded the limits for the ions, chloride (set at 350 mg/L) and nitrate (set at 10 mg/L), for Class C water criteria. All the sites meet the dissolved oxygen, DO, criterion for Class C waters which is set at 5 mg/L. In terms of microbiological load, Site 1 had the least most probable number per ml of water, MPN/ml: total plate count (6720), Coliform (less that detection limit) and E. coli (less than LLD); Site 3 was the most contaminated: total plate count (greater than 70,000), Coliform(48768) and E. Coli (23808). X-ray fluorescence analyses of sediments allowed the determination of elements Na, Mg, Al, P, Si, Cl, K. Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Br, Rb

    Full Text Available El objetivo de este trabajo es caracterizar la gastronomía lacustre en el Alto Lerma, prevaleciente antes y después de la desecación de la Laguna de Lerma, específicamente la de San Pedro Tultepec de Quiroga municipio de Lerma, en el Estado de México. Mediante la aplicación de la técnica etnográfica en la realización de la investigación de campo, se identificaron y localizaron a 30 personas adultas que aún entran a la laguna de Chimaliapan o Lerma, o que tienen conocimiento sobre los ingredientes lacustres y las preparaciones culinarias elaboradas con ellos. Además se realizaron visitas a los mercados locales e incursiones en la laguna y áreas aledañas con la guía de lugareños conocedores del entorno, con el fin de obtener información sobre estos productos. Se encontró que todavía se recolectan especies vegetales como nopales, hongos, papas de agua o apacloles y quelites, entre ellos berros o tiernitos y quintoniles. Asimismo, se aprovechan especies animales como patos, carpas, atepocates, ranas, acociles y ajolotes. Menos del 1% de la población estudiada aún elabora platillos basados en ingredientes extraídos de la laguna. Se preparan tamales de pescado, rana o carpa, acociles, hueva de carpa, carpas y patos de diversas maneras, chile relleno de támbulas y atepocates, y ranas empanizadas o fritas. Con base en lo anterior, se concluye, que a pesar de estar contaminada, todavía se extrae de la laguna de Chimaliapan una gran variedad de flora y fauna que se emplea para la alimentación, lo cual indica que estos recursos bióticos son una importante fuente para muchas familias, y que tienen un "buen potencial" de aprovechamiento.

    The Sigma /sup -/ p and Xi /sup -/d total cross sections have been measured to a statistical accuracy of +or-1% and +or-0.5%, respectively, at five momenta from 7.45 to 136.9 GeV/c, using the hyperon beam at the CERN SPS. The Xi /sup -/p and Xi /sup -/d total cross sections have also been measured to the same statistical accuracy at 101.5 and 133.8 GeV/c. The systematic uncertainty at each momentum is estimated to be of the order of +or-0.5%. The hyperon- nucleon cross sections are shown to be rising with energy, and the data are compared with various phenomenological models. (18 refs).

    This study deals with Late Quaternary palaeoenvironmental variability in Iberia reconstructed from terrestrial archives. In southern Iberia, endorheic basins of the Betic Cordilleras are relatively common and contain salt or fresh-water lakes due to subsurface dissolution of Triassic evaporites. Such precipitation or ground-water fed lakes (called Lagunas in Spanish) are vulnerable to changes in hydrology, climate or anthropogenic modifications. The largest Spanish salt lake, Laguna de Fuente de Piedra (Antequera region, S-Spain), has been investigated and serves as a palaeoenvironmental archive for the Late Pleistocene to Holocene time interval. Several sediment cores taken during drilling campaigns in 2012 and 2013 have revealed sedimentary sequences (up to 14 m length) along the shoreline. A multi-proxy study, including sedimentology, geochemistry and physical properties (magnetic susceptibility) has been performed on the cores. The sedimentary history is highly variable: several decimetre thick silty variegated clay deposits, laminated evaporites, and even few-centimetre thick massive gypsum crystals (i.e., selenites). XRF analysis was focussed on valuable palaeoclimatic proxies (e.g., S, Zr, Ti, and element ratios) to identify the composition and provenance of the sediments and to delineate palaeoenvironmental conditions. First age control has been realized by AMS-radiocarbon dating. The records start with approximately 2-3 m Holocene deposits and reach back to the middle of MIS 3 (GS-3). The sequences contain changes in sedimentation rates as well as colour changes, which can be summarized as brownish-beige deposits at the top and more greenish-grey deposits below as well as highly variegated lamination and selenites below ca. 6 m depth. The Younger Dryas, Bølling/Allerød, and the so-called Mystery Interval/Last Glacial Maximum have presumably been identified in the sediment cores and aligned to other climate records. In general, the cores of the Laguna de

    The ability of mathematical communication is one of the goals of learning mathematics expected to be mastered by students. However, reality in the field found that the ability of mathematical communication the students of grade XI IPA SMA Negeri 14 Padang have not developed optimally. This is evident from the low test results of communication skills mathematically done. One of the factors that causes this happens is learning that has not been fully able to facilitate students to develop mathematical communication skills well. By therefore, to improve students' mathematical communication skills required a model in the learning activities. One of the models learning that can be used is Problem Based learning model Learning (PBL). The purpose of this study is to see whether the ability the students' mathematical communication using the PBL model better than the students' mathematical communication skills of the learning using conventional learning in Class XI IPA SMAN 14 Padang. This research type is quasi experiment with design Randomized Group Only Design. Population in this research that is student of class XI IPA SMAN 14 Padang with sample class XI IPA 3 and class XI IPA 4. Data retrieval is done by using communication skill test mathematically shaped essay. To test the hypothesis used U-Mann test Whitney. Based on the results of data analysis, it can be concluded that the ability mathematical communication of students whose learning apply more PBL model better than the students' mathematical communication skills of their learning apply conventional learning in class XI IPA SMA 14 Padang at α = 0.05. This indicates that the PBL learning model effect on students' mathematical communication ability.

    Seismic reflection and refraction data provide insights into the sedimentary infill and the underlying volcanic structure of Laguna Potrok Aike, a maar lake situated in the Pali Aike Volcanic Field, Southern Patagonia. The lake has a diameter of ~3.5 km, a maximum water depth of ~100 m and a presumed age of ~770 ka. Its sedimentary regime is influenced by climatic and hydrologic conditions related to the Antarctic Circumpolar Current, the Southern Hemispheric Westerlies and sporadic outbreaks of Antarctic polar air masses. Multiproxy environmental reconstructions of the last 16 ka document that this terminal lake is highly sensitive to climate change. Laguna Potrok Aike has recently become a major focus of the International Continental Scientific Drilling Program and was drilled down to 100 m below lake floor in late 2008 within the PASADO project. The sediments are likely to contain a continental record spanning the last ca. 80 kyrs unique in the South American realm. Seismic reflection data show relatively undisturbed, stratified lacustrine sediments at least in the upper ~100 m of the sedimentary infill but are obscured possibly by gas and/or coarser material in larger areas. A model calculated from seismic refraction data reveals a funnel-shaped structure embedded in the sandstone rocks of the surrounding Santa Cruz Formation. This funnel structure is filled by lacustrine sediments of up to 370 m in thickness. These can be separated into two distinct subunits with low acoustic velocities of 1500-1800 m s-1 in the upper subunit pointing at unconsolidated lacustrine muds, and enhanced velocities of 2000-2350 m s-1 in the lower subunit. Below these lacustrine sediments, a unit of probably volcanoclastic origin is observed (>2400 m s-1). This sedimentary succession is well comparable to other well-studied sequences (e.g. Messel and Baruth maars, Germany), confirming phreatomagmatic maar explosions as the origin of Laguna Potrok Aike.

  7. Groundwater flow in a closed basin with a saline shallow lake in a volcanic area: Laguna Tuyajto, northern Chilean Altiplano of the Andes.

    Laguna Tuyajto is a small, shallow saline water lake in the Andean Altiplano of northern Chile. In the eastern side it is fed by springs that discharge groundwater of the nearby volcanic aquifers. The area is arid: rainfall does not exceed 200mm/year in the rainiest parts. The stable isotopic content of spring water shows that the recharge is originated mainly from winter rain, snow melt, and to a lesser extent from some short and intense sporadic rainfall events. Most of the spring water outflowing in the northern side of Laguna Tuyajto is recharged in the Tuyajto volcano. Most of the spring water in the eastern side and groundwater are recharged at higher elevations, in the rims of the nearby endorheic basins of Pampa Colorada and Pampa Las Tecas to the East. The presence of tritium in some deep wells in Pampa Colorada and Pampa Las Tecas indicates recent recharge. Gas emission in recent volcanoes increase the sulfate content of atmospheric deposition and this is reflected in local groundwater. The chemical composition and concentration of spring waters are the result of meteoric water evapo-concentration, water-rock interaction, and mainly the dissolution of old and buried evaporitic deposits. Groundwater flow is mostly shallow due to a low permeability ignimbrite layer of regional extent, which also hinders brine spreading below and around the lake. High deep temperatures near the recent Tuyajto volcano explain the high dissolved silica contents and the δ(18)O shift to heavier values found in some of the spring waters. Laguna Tuyajto is a terminal lake where salts cumulate, mostly halite, but some brine transfer to the Salar de Aguas Calientes-3 cannot be excluded. The hydrogeological behavior of Laguna Tuyajto constitutes a model to understand the functioning of many other similar basins in other areas in the Andean Altiplano. Copyright © 2015 Elsevier B.V.

    Lopez, C.; Al-Qudah, O. M.

    2017-12-01

    Laguna Madre is an important lagoon in the coast of Texas. It is one of the seven hypersaline lagoons in the world. Due to inflow of water with extreme amounts of phosphorus and nitrates and the low inflow of freshwater, the lagoon has high amount of phosphorus and nitrates which can be harmful for fish and plants situated in the lagoon. The goal is to be able to perform a filtration method with citrus peels biochar, and then to evaluate and compare the produced biochar, zeolite, and activated carbon as an infiltration filter by assessing reductions of nitrogen and phosphorus compounds, as well as sum selected trace elements. Furthermore, the current research will investigate how long the cleaning capacity of biochar lasts and how the performance of the filter changes under an increased load of contaminants. The performance of biochar from different parent materials and recycling options for the used filter materials are also included in this research.

    Laguna Grande is a 50-hectare lagoon in the municipio of Fajardo, located in the northeasternmost part of Puerto Rico. Hydrologic, water-quality, and biological data were collected in the lagoon between March 2007 and February 2009 to establish baseline conditions and determine the health of Laguna Grande on the basis of preestablished standards. In addition, a core of bottom material was obtained at one site within the lagoon to establish sediment depositional rates. Water-quality properties measured onsite (temperature, pH, dissolved oxygen, specific conductance, and water transparency) varied temporally rather than areally. All physical properties were in compliance with current regulatory standards established for Puerto Rico. Nutrient concentrations were very low and in compliance with current regulatory standards (less than 5.0 and 1.0 milligrams per liter for total nitrogen and total phosphorus, respectively). The average total nitrogen concentration was 0.28 milligram per liter, and the average total phosphorus concentration was 0.02 milligram per liter. Chlorophyll a was the predominant form of photosynthetic pigment in the water. The average chlorophyll-a concentration was 6.2 micrograms per liter. Bottom sediment accumulation rates were determined in sediment cores by modeling the downcore activities of lead-210 and cesium-137. Results indicated a sediment depositional rate of about 0.44 centimeter per year. At this rate of sediment accretion, the lagoon may become a marshland in about 700 to 900 years. About 86 percent of the community primary productivity in Laguna Grande was generated by periphyton, primarily algal mats and seagrasses, and the remaining 14 percent was generated by phytoplankton in the water column. Based on the diel studies the total average net community productivity equaled 5.7 grams of oxygen per cubic meter per day (2.1 grams of carbon per cubic meter per day). Most of this productivity was ascribed to periphyton and macrophytes

    Robotic rectal surgery is becoming increasingly more popular among colorectal surgeons. However, time spent on robotic platform docking, arm clashing and undocking of the platform during the procedure are factors that surgeons often find cumbersome and time consuming. The newest surgical platform, the da Vinci Xi, coupled with integrated table motion can help to overcome these problems. This technical note aims to describe a standardised operative technique of single docking robotic rectal surgery using the da Vinci Xi system and integrated table motion. A stepwise approach of the da Vinci docking process and surgical technique is described accompanied by an intra-operative video that demonstrates this technique. We also present data collected from a prospectively maintained database. 33 consecutive rectal cancer patients (24 male, 9 female) received robotic rectal surgery with the da Vinci Xi during the preparation of this technical note. 29 (88%) patients had anterior resections, and four (12%) had abdominoperineal excisions. There were no conversions, no anastomotic leaks and no mortality. Median operation time was 331 (249-372) min, blood loss 20 (20-45) mls and length of stay 6.5 (4-8) days. 30-day readmission rate and re-operation rates were 3% (n = 1). This standardised technique of single docking robotic rectal surgery with the da Vinci Xi is safe, feasible and reproducible. The technological advances of the new robotic system facilitate the totally robotic single docking approach.

    Full Text Available xiǎojiě ( 小姐, miss is a popular form of address in contemporary Chinese; generally speaking, it is defined as a title for “unmarried girl”. This form has multiple connotations,. Given recent changes in society, some think that, xiǎojiě (小姐 will become a widely-used form of address, while others think that young females will come to consider the title repulsive. None can have the final say, this is because the synchronic language differences are not only the result of the synchronic change but also possibly its sign. Since synchronic differences could not only be a result of diachronic change but also could herald further change, it is not clear what direction xiǎojiě ( 小姐 will take. In the language conflicts, When two language varieties conflict, the more common variety usually influences the less common. A field investigation in large cities throughout China thus allows us not only to draw A Distributional Map of Pragmatic Features of the Title xiǎojiě (小姐, but also enables us to see its diachronic possibilities.

    The main purpose of this work is to obtain the fluence of fast neutrons recorded within four specimens of carbon steel, similar to the material having the vessels of the BWR reactors of the nuclear power plant of Laguna Verde when subjected to neutron flux in a experimental facility of the TRIGA Mark III reactor, calculating an irradiation time to age the material so accelerated. For the calculation of the neutron flux in the specimens was used the Monte Carlo code MCNP5. In an initial stage, three sheets of natural molybdenum and molybdenum trioxide (MoO{sub 3}) were incorporated into a model developed of the TRIGA reactor operating at 1 M Wth, to calculate the resulting activity by setting a certain time of irradiation. The results obtained were compared with experimentally measured activities in these same materials to validate the calculated neutron flux in the model used. Subsequently, the fast neutron flux received by the steel specimens to incorporate them in the experimental facility E-16 of the reactor core model operating at nominal maximum power in steady-state was calculated, already from these calculations the irradiation time required was obtained for values of the neutron flux in the range of 10{sup 18} n/cm{sup 2}, which is estimated for the case of Laguna Verde after 32 years of effective operation at maximum power.

    Laguna Bacalar is a sulfate-rich freshwater lake on the Yucatan Peninsula that hosts large microbialites. High sulfate concentrations distinguish Laguna Bacalar from other freshwater microbialite sites such as Pavilion Lake and Alchichica, Mexico, as well as from other aqueous features on the Yucatan Peninsula. While cyanobacterial populations have been described here previously, this study offers a more complete characterization of the microbial populations and corresponding biogeochemical cycling using a three-pronged geobiological approach of microscopy, high-throughput DNA sequencing, and lipid biomarker analyses. We identify and compare diverse microbial communities of Alphaproteobacteria, Deltaproteobacteria, and Gammaproteobacteria that vary with location along a bank-to-bank transect across the lake, within microbialites, and within a neighboring mangrove root agglomeration. In particular, sulfate-reducing bacteria are extremely common and diverse, constituting 7%-19% of phylogenetic diversity within the microbialites, and are hypothesized to significantly influence carbonate precipitation. In contrast, Cyanobacteria account for less than 1% of phylogenetic diversity. The distribution of lipid biomarkers reflects these changes in microbial ecology, providing meaningful biosignatures for the microbes in this system. Polysaturated short-chain fatty acids characteristic of cyanobacteria account for Bacalar microbialites. By contrast, even short-chain and monounsaturated short-chain fatty acids attributable to both Cyanobacteria and many other organisms including types of Alphaproteobacteria and Gammaproteobacteria constitute 43%-69% and 17%-25%, respectively, of total abundance in microbialites. While cyanobacteria are the largest and most visible microbes within these microbialites and dominate the mangrove root agglomeration, it is clear that their smaller, metabolically diverse associates are responsible for significant biogeochemical cycling in this

    Full Text Available The «Laguna Grande de Quero», is a saline pond located on the aluvial system from the Cigüela and Riansares rivers. The pond's underground impermeable materials are claystone with gypsum from the Triassic ages. On the next reliefs appears gypsiferous-detrital and calcareous materials from the Tertiary ages. A model have been created for the evaporative process, correcting the saline effect bearing in mind the climatic parameters; the conclusions obtained are coherents with the experimental data, which have been obtained in two experimental pools placed for the evaporative- concentration processes chasing. The experimental precipitation sequence obtained was: calcite + gypsum → bloedite + thenardite → bloedite → epsomite + halite. This sequence has been studied about saits generated on the air-brine interface. Moreover coincide with the foreseeable theoric sequence, according to Valyashko diagrams. In the natural environment appears facies and paragenesis associations coherents with the experimental data. During the evaporative process to specific gravity and concentration evolution graphics show a stagnancy period, «plateau effect», that it seams to coincide with a differential heating from the depth waters. The explanation of this effect can be related with the salts dissolution previously formed.La Laguna Grande de Quero, se ubica en el sistema aluvial de los ríos Cigüela-Riansares.

    Full Text Available The aim of this paper is to present the history of the Dōnghú, Wūhuán and Xiānbēi Proto-Mongolian tribes in the period from the 4th century B.C. to the end of the 3rd century A.D. The history of the ancient nomadic peoples who lived north of China is written in Chinese dynasty chronicles. Proto-Mongolian tribes from the 1st century B.C. are called Dōnghú in Chinese sources. The earliest news on them originates from the Warring States Period (4th – 3rd century B.C., and tells of a conflict with the northern Chinese states. Other types of sources on the history of the Proto-Mongolian tribes are archaeological findings, which associate Mongolian ethnogenesis with slab grave cultures and the Lower Xiàjiādiàn. Linguists find the materials for the research on Mongolian ethnogenesis in the Altaic linguistic family, which the Mongolian language belongs to as well. Based on the mentioned sources, the change in the political situation in the steppes at the end of the 3rd century B.C., when the people of Xiōngnú created a powerful state and conquered the Dōnghúes, is described in the paper. The remains of the shattered Dōnghúes, who had mostly migrated to the north, have been recorded in Chinese chronicles under new topoethnonyms: Xiānbēi and Wūhuán. The weakening and fall of the Xiōngnúes’ state enabled the Proto-Mongolian tribes to re-enter the historical scene. At the end of the 1st century B.C. the Chinese Hàn Empire firstly established relations with the Wūhuán tribes and in the middle of the 1st century A.D. with the Xiānbēi tribes, too. In the beginning both tribal alliances acknowledged the supreme authority of China and carried out frontier service. Under the guidance of tribal chiefs the tribes started to run an independent policy and attack China’s border areas during the 2nd century A.D. In the conclusion, the author describes the period when the Wūhuán and Xiānbēi tribes were at the peak of their power

    Although one double hypernuclei was discovered in KEK-E176 experiment, its species was not fixed and there are two interpretations for it. One is {sub {Lambda}{Lambda}}{sup 10}Be(a) and the other is {sub {Lambda}{Lambda}}{sup 13}B(b). The property of {Lambda}-{Lambda} interaction is repulsive if we adopt interpretation (a) and it is attractive if we adopt interpretation (b). In this study we analyze the formation of double, single and twin hypernuclei form stopped {Xi}{sup -} at rest on {sup 12}C with microscopic transport model and clarify the dependence of the formation probability on the property of {Lambda}-{Lambda} interaction.

    The production of the strange and double-strange baryon resonances ($\\Sigma(1385)^{\\pm}$, $\\Xi(1530)^{0}$) has been measured at mid-rapidity ($\\left | y \\right |<0.5$) in proton-proton collisions at $\\sqrt{s}$ = 7 TeV with the ALICE detector at the LHC. Transverse momentum spectra for inelastic collisions are compared to QCD-inspired models, which in general underpredict the data. A search for the $\\phi(1860)$ pentaquark, decaying in the $\\Xi\\pi$ channel, has been carried out but no evidence is seen.

    Full Text Available Cada vez entendemos mejor que ni siquiera una TOE podría ofrecer una explicación completa de la realidad. A decir verdad, en principio, no existen «agujeros» para la ciencia que pudieran ser llenados por la teología. Si los teólogos desean evitar todo dios-tapa-agujeros deben asegurarse de que no piensan a Dios actuando en el nivel de la causalidad eficiente. No obstante, incluso a nivel cognitivo, sigue abierta una laguna fundamental entre la descripción científica del mundo y una visión global de la realidad tal como se experiencia en «el más amplio y rico marco de la vida personal», usando una formulación de Polkinghorne (1996, xi. Esta laguna no tiene nada que ver con cualquier clase de agujero relacionado con el dios-tapa-agujeros. Para una explicación suficiente de este más amplio contexto vital, sin embargo, debe tenderse un puente entre la ciencia y el resto de la vida. La necesidad de cruzar esta laguna se muestra en el hecho de que los científicos alcanzan cuestiones límite que la ciencia por sí misma no puede responder.

    This volume presents the results of the starter event analysis and the event tree analysis for the Unit 1 of the Laguna Verde nuclear power station. The starter event analysis includes the identification of all those internal events which cause a disturbance to the normal operation of the power station and require mitigation. Those called external events stay beyond the reach of this study. For the analysis of the Laguna Verde power station eight transient categories were identified, three categories of loss of coolant accidents (LOCA) inside the container, a LOCA out of the primary container, as well as the vessel break. The event trees analysis involves the development of the possible accident sequences for each category of starter events. Events trees by systems for the different types of LOCA and for all the transients were constructed. It was constructed the event tree for the total loss of alternating current, which represents an extension of the event tree for the loss of external power transient. Also the event tree by systems for the anticipated transients without scram was developed (ATWS). The events trees for the accident sequences includes the sequences evaluation with vulnerable nucleus, that is to say those sequences in which it is had an adequate cooling of nucleus but the remoting systems of residual heat had failed. In order to model adequately the previous, headings were added to the event tree for developing the sequences until the point where be solved the nucleus state. This process includes: the determination of the failure pressure of the primary container, the evaluation of the environment generated in the reactor building as result of the container failure or cracked of itself, the determination of the localization of the components in the reactor building and the construction of boolean expressions to estimate the failure of the subordinated components to an severe environment.

    Intraoperative monitoring of the cranial nerve XI (CN XI) may decrease shoulder disability following modified radical neck dissection. Prospective study was designed comparing results of Constant Shoulder Score (CSS), Shoulder Pain and Disability Index (SPADI) and EMG score of the trapezius muscle (mT) before and after surgery. One side of the neck was monitored during surgery with intraoperative nerve monitor. EMG scores of the mT 6 months postoperatively were statistically better on monitored as compared to the non-monitored side of the neck (p = 0.041), while the differences of the CSS and SPADI were not statistically significant. Patients with better EMG scores of the mT at 6 weeks recuperated better and with smaller decrease of the CSS. Intraoperative monitoring is beneficial at the beginning of the surgeon's learning curve and in the process of familiarizing with anatomical variation of the CN XI.

    We aimed to compare perioperative outcomes for procedures using the latest generation of da Vinci robot versus its previous version in rectal cancer surgery. Fifty-three patients undergoing robotic rectal cancer surgery between January 2010 and March 2015 were included. Patients were classified into 2 groups (Xi, n=28 vs. Si, n=25) and perioperative outcomes were analyzed. The groups had significant differences including operative procedure, hybrid technique and redocking (P>0.05). In univariate analysis, the Xi group had shorter console times (265.7 vs. 317.1 min, P=0.006) and total operative times (321.6 vs. 360.4 min, P=0.04) and higher number of lymph nodes harvested (27.5 vs. 17.0, P=0.008). In multivariate analysis, Xi robot was associated with a shorter console time (odds ratio: 0.09, P=0.004) with no significant differences regarding other outcomes. Both generations of da Vinci robot led to similar short-term outcomes in rectal cancer surgery, but the Xi robot allowed shorter console times.

    Quality Assurance (QA) in Mexico started with the construction of the Laguna Verde Nuclear Power Plant. The Nuclear Regulatory Body, based in the adopted regulation, required the use of Quality Assurance in the design, construction and operation of the Plant. This paper describes the evolution of QA from its beginnings, through its developing phase up to this time, and shows the role of the Regulatory Body, which has participated actively in the implantation of QA in a properly manner, enforcing the utility in avoiding deviations and non-compliancies with the established regulation.

    The Sigma /sup -/ p and Xi /sup -/d total cross sections have been measured to a statistical accuracy of +or-1% and +or-0.5%, respectively, at five momenta from 7.45 to 136.9 GeV/c, using the hyperon beam at the CERN SPS. The Xi /sup -/p and Xi /sup -/d total cross sections have also been measured to the same statistical accuracy at 101.5 and 133.8 GeV/c. The systematic uncertainty at each momentum is estimated to be of the order of +or-0.5%. The hyperon- nucleon cross sections are shown to be rising with energy, and the data are compared with various phenomenological models. (18 refs).

    This study aims to characterize the reproductive patterns in Asinina de Miranda jennies during the non-breeding season. Reproductive activity was surveyed in 12 females, aged between 3 and 18 years old, using ultrasound and teasing with a jack. The animals were monitored from September to April, six in each consecutive year. Of these 12 females, nine showed disruption to the normal pattern of ovarian activity during the non-breeding season. Loss of normal cyclicity included anoestrus (41.7%), silent ovulatory oestrus (25%), and persistence of corpus luteum (8.3%). Only three females maintained a regular cyclic pattern with oestrous behaviour during the non-breeding season. Anoestrus began in early November and lasted for an average of 147 ± 28 days (113-191 days), ending near to the spring equinox. Onset of silent oestrous cycles began more erratically, between October and February. In both groups the first behavioural ovulation of the year occurred around the time of the spring equinox. Disrupted reproductive activity was preceded by a shorter oestrous cycle only in females entering anoestrus. The mean follicle size in the first ovulation of the year was larger than in the reproductive season (44.7 ± 2.45 mm vs 39.2 ± 3.60 mm) in anoestrous jennies with protracted oestrus. Though age and body condition score (BCS) were associated, changes in BCS below a threshold of four points (for anoestrus) and five points (for silent oestrus) contributed greatly to disruption of reproductive cycles. BCS in females with regular oestrous cycles during the winter season remained unchanged or exceeded five points prior to the winter solstice. © 2015 Blackwell Verlag GmbH.

    Laguna Tuyajto is a small, shallow saline water lake in the Andean Altiplano of northern Chile.

    1982-01-01

    The Owner of a nuclear power plant has the regulatory commitment to perform Section XI in-service inspection throughout the service life of a plant. In anticipation of what will be needed to perform adequately the required examinations and tests, sub-article IWA-1500 of Section XI not only requires that sufficient access be provided to accommodate equipment and inspection personnel but also requires that other provisions be considered such as: component surface preparations, material selections, shielding, removal and storage of hardware, handling equipment, and provisions for repairs and replacements. It is, therefore, the owner's and the architect engineer's responsibility to ensure that proper design and access provisions are incorporated to enable the owner to meet his commitments. Since the architect engineer usually has the prime responsibility for the implementation of design criteria, the owner must ensure that these provisions be considered in each phase of design and construction. The benefits of this can result in shorter outages, more meaningful examinations and tests and less radiation exposure of inspection personnel. This paper will address in detail those topics that affect design and access provisions which need to be considered during the design and construction of a nuclear power plant. (author)

    With the urban eco-environment increasingly deteriorating, the ecosystem services provided by modern urban agriculture are exceedingly significant to maintain and build more suitable environment in a city. Taking Xi' an metropolitan as the study area, based on remote sensing data, DEM data and the economic and social statistics data, the water and soil conservation service of the agricultural ecosystems was valued employing the remote sensing and geographic information system method, covering the reduction values on land waste, soil fertility loss and sediment loss from 2000 to 2011, and analyzed its changes in time and space. The results showed that during the study period, the total value of water and soil conservation service provided by agricultural systems in Xi' an metropolitan was increased by 46,086 and 33.008 billion yuan respectively from period of 2000 to 2005 and from 2005 to 2011. The cultivated land (including grains, vegetables and other farming land), forest (including orchard) and grassland provided higher value on the water and soil conservation service than waters and other land use. Ecosystem service value of water and soil conserva- tion provided by agriculture was gradually decreasing from the southern to the northern in Xi' an metropolitan. There were significantly positive relationship between the ecosystem service value and the vegetation coverage. Forest, orchard and grassland distributed intensively in the southern which had higher vegetation coverage than in northern where covered by more cultivated land, sparse forest and scattered orchard. There were significantly negative correlation between the urbanization level and the value of water and soil conservation. The higher level of urbanization, the lower value there was from built-up area to suburban and to countryside within Xi' an metropolitan.

    Full Text Available The KIDS model (Kielstau Discharge Simulation model is a simple rainfall-runoff model developed originally for the Kielstau catchment. To extend its range of application we applied it to a completely different catchment, the XitaoXi catchment in China. Kielstau is a small (51 km2 lowland basin in Northern Germany, with large proportion of wetland area. And XitaoXi is a mesoscale (2271 km2 mountainous basin in the south of China. Both catchments differ greatly in size, topography, landuse, soil properties, and weather conditions. We compared two catchments in these features and stress on the analysis how the specific catchment characteristics could guide the adaptation of KIDS model and the parameter estimation for streamflow simulation. The Nash and Sutcliffe coefficient was 0.73 for Kielstau and 0.65 for XitaoXi. The results suggest that the application of KIDS model may require adjustments according to the specific physical background of the study basin.

    The recent data taken by the CLAS Collaboration at the Thomas Jefferson National Accelerator Facility for the reaction of $\\gamma p \\to K^+ K^+ \\Xi^-$ are reanalyzed within a relativistic meson-exchange model of hadronic interactions. The present model is an extension of the one developed in an earlier work by Nakayama, Oh, and Haberzettl [Phys. Rev. C 74, 035205 (2006)]. In particular, the role of the spin-5/2 and -7/2 hyperon resonances, which were not included in the previous model, is investigated in the present study. It is shown that the contribution of the $\\Sigma(2030)$ hyperon having spin-7/2 and positive parity has a key role to bring the model predictions into a fair agreement with the measured data for the $K^+\\Xi^-$ invariant mass distribution.

    The new fuel designs for operation cycles more long have regions of uncertainty bigger that those of the old fuels, and therefore, they can have oscillations of power when an event is presented that causes that the reactor operates to high power and low flow of coolant. During the start up of the reactor there are continued procedures that avoid that oscillations are presented with that which makes sure the stable behavior of the reactor. However, when the reactor is operating to nominal conditions and they are shot or they are transferred to low speed the recirculation pumps, it cannot make sure that the reactor doesn't present oscillations of power when entering to the restricted operation regions. The methods of stability analysis commonly use signs of neutronic noise that require to be stationary, but after a transitory one where they commonly get lost the recirculation pumps the signs they don't have the required characteristics, for what they are used with certain level of uncertainty by the limited validity of the models. In this work the Prony method is used to determine the reactor stability, starting from signs of transitory and it is compared with autoregressive models. Four events are analyzed happened in the Laguna Verde power plant where the reactor was in the area of high power and low flow of coolant, giving satisfactory results. (Author)

    Full Text Available Charophytes are submerged macrophyte algae often found in diverse aquatic habitats. Chara-dominated lakes are typically hard water, calcium-rich and low in phosphate. La Colgada is a 18 m deep, 103 ha small lake located in a tourist area, which has partly resulted in nutrient increases in recent years. Chara hispida var. major (Hartm. R.D. Wood and Chara hispida f. polyacantha (A. Braun R.D. Wood meadows are extensive in this ecosystem, but their distribution are influenced by human activities. Negligible densities of C. hispida, always covered by epiphytes, were recorded in the shores adjacent to tourist areas. Horizontal cover and biomass distributions were heterogeneous throughout the lake (0,95 ± 0,55 kg DW•m-2, with minimum values nearby the tourist area (0,68 ± 0,32 kg DW•m-2. Charophyte biomass was inversely related to depth in areas not influenced by anthropogenic impacts. However, that relationship did not occur in anthropized areas. The biomass range of Charophytes in La Colgada lake, 0,22-2,27 kg DW•m-2, was much higher than that recorded in other world lakes and wetlands.Los carófitos son algas macrófitas que viven sumergidas en aguas con características físico-químicas muy diferentes.

    Global climate and environmental changes are endangering global water resources; and several approaches have been tested to manage and reduce the pressure on these decreasing resources. This study uses the case study of Xi'an City in China to test reasonable and effective methods to address water resource shortages. The study generated a framework combining ecosystem services and water resource management. Seven ecosystem indicators were classified as supply services, regulating services, or cultural services. Index values for each indicator were calculated, and based on questionnaire results, each index's weight was calculated. Using the Likert method, we calculated ecosystem service supplies in every region of the city. We found that the ecosystem's service capability is closely related to water resources, providing a method for managing water resources. Using Xi'an City as an example, we apply the ecosystem services concept to water resources management, providing a method for decision makers.

    The National Commission of Nuclear Safety and Safeguards (CNSNS) requires to have calculation tools which allows it to make analysis independent of the behavior of the reactor core of Laguna Verde nuclear power plant (CNLV) with the purpose to support the evaluation and discharge activities of the fuel recharges licensing. The software package Fms (Fuel Management System) allows to carry out an analysis of the core of the BWR type reactors along the operation cycle to detect possible anomalies and/or helping in the fuel management. In this work it is reproduced the flow-power for the CNLV using the Presto code of the Fms software package. The comparison of results with the map used by the operators of CNLV shows good agreement between them. Another exercise carried out was the changes study that the axial and radial power outlines undergo as well as the thermohydraulic parameters (LHGR, APLHGR, CPR) when moving a control rod. The obtained results show that is had the experience to effect analysis of the reactor behavior using the Presto-Fms code therefore the study of the rest of the software package for the obtention of nuclear parameters used in this code is recommended.

    Widespread demographic shifts in the southern Maya lowlands at the end of the Classic period have been attributed to environmental change caused by human activity and/or climate variability. Fire was essential to landscape modification and was a primary agent of environmental change associated with prehispanic land use. While several studies have provided insight into the dynamic relationship between natural and anthropogenic drivers of change, defining the specific interplay between natural environmental change, human modification of the environment, and cultural response to changes remains a persistent challenge. Here we present the results of a multi-proxy study that reconstructs fire history, agricultural land use, and environmental change during and after Pre-Columbian Maya settlement. Results are interpreted in the context of settlement history as inferred from archaeological mapping around the study site. Our findings suggest landscape disturbance, as indicated by erosion, local burning, and nearby maize agriculture, was at its peak during the Early Classic period. This disturbance was likely due to large-scale settlement at the nearby site of Witzna'. All proxies indicate a slow decline in disturbance into the Late Classic period, beginning around 1300 cal yr BP. Cival and Chanchich, two proximal site centers to the south of Laguna Ek'Naab, supported their largest populations during the Late Preclassic and Late Classic, with little or no settlement during the Early Classic. The data from Laguna Ek'Naab suggests that Witzna' may have been an important center during the Early Classic. Whether the decreasing environmental degradation after 1240 cal yr BP is do to a decline in local population or changing land use strategies is not discernable based on the data thus far. However, the near complete absence of burning and continued decrease in erosion from 1240-1090 cal yr BP suggests little anthropogenic activity in the area. Burning resumes in the watershed

    On 2008 May 2, Chandra observed the X-ray spectrum of xi Boo (G8 V+K4 V), resolving the binary for the first time in X-rays and allowing the coronae of the two stars to be studied separately. With the contributions of ξ Boo A and B to the system's total X-ray emission now observationally established (88.5% and 11.5% respectively), consideration of mass loss measurements for GK dwarfs of various activity levels (including one for xi Boo) leads to the surprising conclusion that xi Boo B may dominate the wind from the binary, with xi Boo A's wind being very weak despite its active corona. Emission measure (EM) distributions and coronal abundances are computed for both stars and compared with Chandra measurements of other moderately active stars with G8-K5 spectral types, all of which exhibit a narrow peak in EM near log T = 6.6, indicating that the coronal heating process in these stars has a strong preference for this temperature. As is the case for the Sun and many other stars, our sample of stars shows coronal abundance anomalies dependent on the first ionization potential (FIP) of the element. We see no dependence of the degree of FIP effect on activity, but there is a dependence on spectral type, a correlation that becomes more convincing when moderately active main-sequence stars with a broader range of spectral types are considered. This clear dependence of coronal abundances on spectral type weakens if the stellar sample is allowed to be contaminated by evolved stars, interacting binaries or extremely active stars with logLX 29, explaining why this correlation has not been recognized in the past.

    This work presents the improvements to the integral model of the nuclear power plant of Laguna Verde for the RELAP/SCDAPSIM code, for the simulation of transients and severe accidents. The model includes a new detailed geometry of the steam lines, as well as improvements in the performance of the emergency systems. A primary containment model has also been created, which will be used to analyze the effect of safety valve and relief valve discharges to the wet well suppression pool and the effect of the rupture of a recirculation loop on the dry well. The simulations performed with the new model show that the changes made improve the prediction of the phenomenology involved during transients and accidents. (Author)

    Detailed physical and chemical characteristic analysis was performed on the spent cation and anion resins in the mixed bed from Xi'an Pulse Reactor water purifying system.The exchange performance variations of used resins and the contributions from different factors to the variation were discussed.Based on the obtained information of the impurities in the used resin, the contamination state of the water in the Xi'an Pulse Reactor water pool, the corrosion state of the structural material in the reactor was presented. The spent anion resin almost completely losses its exchange performance,while the remaining exchange capacity in the spent cation resin is still high.The radiation field from the reactor operation contributes little to the degradation of the performance of the resins. The exchange capacity loss of the spent anion resin is due to the exchange of its active groups into abundant carbonate and a certain amount of organics. The impurity amount in the anion and cation exchange resins is low,which suggests(that) the water in the Xi'an Pulse Reactor water pool is little contaminated. A certain extent of corrosion is occurred on the structural material in the swimming pool of the reactor. The results provide important referential data for the operational safety of the water purifying system of similar research reactor. (authors)

  12. Stress corrosion evaluation on stainless steel 304 pipes in Laguna Verde Nuclear Power Plant

    Inside the frame of the project IAEA/MEX-41044 'Stress corrosion as a starting event of accidents in nuclear plants', and of the institutional project IA-252 under the same name, it was required from the Laguna Verde Nuclear Plant, material equivalent to the one employed in the piping of the primary recycling system. Laguna Verde Nuclear Plant granted two tracks of tubes, that could be used to substitute the ones that are in operation, as is the tube SA-358TP304 CL-QC with transversal welding, designated as ER-316-LQA. According to the report entitles 'Revision of the operational experience related to corrosion in the nuclear plants' it was found that the stress corrosion is the principal mechanism of corrosion present in the nuclear plants. Previous records indicate that sensitized stainless steels are resistant to stress corrosion in testings of constant loading in sea water (3.5% of chlorides approximately) to 80 Centigrade and to 80% of the limit of conveyance and that a solution of 22% of NaCl to 90 Centigrade, produces cracking due to stress corrosion in highly sensitized steels, in tests of speed of slow extension (SSRT), to a speed of 1x10 -6 s -1 . Daniels reports that there is a direct relation between the speed limit of detection of the SSRT test and the concentration of chlorides, for stainless steels tested to 100 Centigrade. The minimum detection speed of susceptibility to stress corrosion for solution to 20% of NaCl, is of 1x10 -7 s -1 . Taking into account these considerations, the employment of a solution with 22% of NaCl to 90 Centigrade to a speed of 1x10 -6 s -1 seems a good choice for the evaluation of stainless steel.

    Full Text Available A utilização da madeira em estruturas está vinculada a condições que permitam sua utilização por muitos anos sem a perda de suas propriedades de resistência e de rigidez. Entretanto, por se tratar de material natural, as estruturas em madeira projetadas podem estar sujeitas ao ataque de agentes biológicos, ação de intempéries, entre outros fatores, requerendo soluções na forma de reparo ou reforço. O presente trabalho objetivou investigar a influência do uso de resina epóxi como agente reparador em vigas danificadas de madeira de Pinus elliottii no cálculo do produto de rigidez à flexão. Para tanto, foi realizado um planejamento experimental completo, tendo a posição dos defeitos provocados (central ou laterais, o uso ou não da resina nos defeitos, e a posição desses defeitos (superior - compressão ou Inferior - tração como fatores. Os resultados da análise estatística revelaram que o uso da resina epóxi nas regiões danificadas das vigas apresentaram valores do produto de rigidez na flexão significativamente superiores quando comparados com as vigas da condição com defeito e sem a resina epóxi. Mesmo sendo significativo o uso da resina nas regiões danificadas, o produto de rigidez à flexão das vigas reparadas foi inferior ao produto de rigidez à flexão das vigas sem defeito (referência, evidenciando a necessidade de outros estudos com outras resinas e outros materiais visando à recuperação total da rigidez da peça de madeira danificada.
