    Papanikolau, N.

    Welcome by the Mayor of Valtetsi Mr. Chairman Ladies and Gentlemen The municipality of Valtetsi welcomes you and wishes success in your work. Arcadia is both a historical and modern region. Moreover, as a name it remained in the western culture recalling a harmonious and peaceful dream, a lost and desirable situation where the human being lived in balance with nature, a region where the person did not feel yet uprooted. For thousands of years the poetic voices retained vivid this eternal bucolic call of simplicity and accessible happiness. Gazing the starlit sky we will always see Kallisto, the daughter of Lykaona, king of Arcadia and her son Arcadian as they were both transformed in to the constellations Major and Minor Ursus because of the erotic libido of Jupiter and the jealousy of Hera. And we will always remember Centaurus Cheirona, the great schoolteacher of ancient heroes, who was the first to name the constellations according to mythology. Finally we would like to thank the patriot Mr. T. Tzioumi who returns to his beautiful village in Arcadia just like Antaios did. In the geographic place that inspired the arcadian ideal, such activities recall in the limelight Arcadia as was dreamed by Europe. Mr. Chairman, ladies and gentlemen, success in your scientific work. The Municipality of Valtetsi and I myself will be always next to you so that your stay at Arcadia will always remain vivid in your memory. Thank you. Nikos Papanikolaou Mayor of Valtetsi

    Peake, H. J.

    1978-01-01

    Conversations were held with the mayors of six Maryland towns to discuss possible models and needs for technology transfer. An unexpected outcome of the discussions was a considerable insight into local problems as perceived by the mayors. Problems, whether administrative, socio-economic, or technological, are different, from town to town, in degree, not in kind. Recognition of this feature of local priorities is vital to any considerations of external assistance.

    2003-08-01

    O detector de ondas gravitacionais Mario Schenberg será sensível a sinais que cheguem à Terra com amplitude h~10-21 e dentro da faixa em frequências que varia de 3,0 a 3,4 kHz. As principais fontes astrofísicas em condições de gerar um sinal detectável pela antena Schenberg são: colapsos estelares que produzam eventos do tipo supernova; instabilidades hidrodinâmicas em estrelas de nêutrons; excitação dos modos fluído (modos f) de estrelas de nêutrons; excitação dos primeiros modos quadrupolares de buracos negros com massa ~ 3,8 M¤; coalescências de estrelas de nêutrons e buracos negros em sistemas binários e, ainda, espiralações de mini-buracos negros. Neste trabalho nós determinamos as taxas de eventos para o Schenberg associadas a dois tipos de fontes: através da de-excitação dos modos f de estrelas de nêutrons e através da coalescência de mini-buracos negros de 0,5 M¤ (que atualmente têm sido colocados como possíveis candidatos a objetos massivos do halo Galáctico). Nós mostramos que esses tipos de fontes poderão produzir sinais em ondas gravitacionais com uma taxa em torno de um evento por ano dentro da banda do Schenberg.

  5. Evolution of a Quaternary peralkaline volcano: Mayor Island, New Zealand

    USGS Publications Warehouse

    Houghton, B.F.; Weaver, S.D.; Wilson, C.J.N.; Lanphere, M.A.

    1992-01-01

    Mayor Island is a Holocene pantelleritic volcano showing a wide range of dispersive power and eruptive intensity despite a very limited range in magma composition of only 2% SiO2. The primary controls on this range appear to have been the magmatic gas content on eruption and a varying involvement of basaltic magma, rather than major-element chemistry of the rhyolites. The ca. 130 ka subaerial history of the volcano contains portions of three geochemical cycles with abrupt changes in trace-element chemistry following episodes of caldera collapse. The uniform major-element chemistry of the magma may relate to a fine balance between rates of eruption and supply and the higher density of the more evolved (Ferich) magmas which could be tapped only after caldera-forming events had removed significant volumes of less evolved but lighter magma. ?? 1992.

  6. Eventos de Desconexao na Cauda de Plasma do Cometa P/Halley

    Voelzke, M. R.; Fahr, H. J.

    2001-08-01

    Observacoes cometárias e de vento solar sao comparadas com o propósito de determinar-se as condicoes do vento solar associadas aos eventos de desconexao (DEs) observados em caudas de plasma cometárias. Os dados cometários sao provenientes do The International Halley Watch Atlas of Large-Scale Phenomena. A análise visual sistemática das imagens do atlas revelou, entre outras estruturas morfológicas, 47 DEs ao longo da cauda de plasma do P/Halley. Estes 47 DEs registrados em 47 imagens distintas permitiram a descoberta de 19 origens de DEs, ou seja, o tempo em que as desconexoes iniciaram foi calculado. Os dados do vento solar sao provenientes de medidas feitas in situ pela sonda espacial IMP-8, as quais foram usadas para elaborar a variacao da velocidade do vento solar, densidade e pressao dinâmica durante o intervalo analisado. O presente trabalho compara as atuais teorias conflitantes, baseadas nos mecanismos de formacao, com o intuito de explicar o fenômeno cíclico dos DEs, ou seja, os efeitos de producao iônica, os efeitos de pressao e os efeitos de reconexao magnética sao analisados. Para cada uma das 19 origens de DEs comparou-se a densidade com a respectiva velocidade do vento solar com o intuito de determinar-se uma possível correlacao entre estas origens e os efeitos de pressao dinâmica. Quando da ocorrência de 6 origens de DEs o IMP-8 nao realizou medidas, nos outros 13 casos 10 origens (77%) mostraram uma anticorrelacao entre velocidade e densidade e apenas 3 (23%) revelaram uma tendência similar entre velocidade e densidade. Portanto, a análise inicial demonstra uma fraca correlacao entre as origens dos DEs e os efeitos de pressao.

  4. The role of a keystone fault in triggering the complex El Mayor-Cucapah earthquake rupture

    NASA Astrophysics Data System (ADS)

    Fletcher, John M.; Oskin, Michael E.; Teran, Orlando J.

    2016-04-01

    The 2010 Mw 7.2 El Mayor-Cucapah earthquake in Baja California, Mexico activated slip on multiple faults of diverse orientations, which is commonly the case for large earthquakes. The critical stress level for fault failure depends on fault orientation and is lowest for optimally oriented faults positioned approximately 30° to the greatest principal compressive stress. Yet, misoriented faults whose positioning is not conducive to rupture are also common. Here we use stress inversions of surface displacement and seismic data to show that the El Mayor-Cucapah earthquake initiated on a fault that, owing to its orientation, was among those that required the greatest stress for failure. Although other optimally oriented faults must have reached critical stress earlier in the interseismic period, Coulomb stress modelling shows that slip on these faults was initially muted because they were pinned, held in place by misoriented faults that helped regulate their slip. In this way, faults of diverse orientations could be maintained at critical stress without destabilizing the network. We propose that regional stress build-up continues until a misoriented keystone fault reaches its threshold and its failure then spreads spontaneously across the network in a large earthquake. Our keystone fault hypothesis explains seismogenic failure of severely misoriented faults such as the San Andreas fault and the entire class of low-angle normal faults.

    Introduccion La diabetes mellitus y las demencias constituyen dos problemas crecientes de salud entre la población adulta mayor del mundo y en particular de los paises en desarrollo. Hacen falta estudios longitudinales sobre el papel de la diabetes como factor de riesgo para demencia. Objetivo Determinar el riesgo de demencia en sujetos Mexicanos con diabetes mellitus tipo 2. Materiales y Metodos Los sujetos diabéticos libres de demencia pertenecientes al Estudio Nacional de Salud y Envejecimiento en México fueron evaluados a los dos años de la línea de base. Se estudió el papel de los factores sociodemográficos, de otras comorbilidades y del tipo de tratamiento en la conversión a demencia. Resultados Durante la línea de base 749 sujetos (13.8%) tuvieron diabetes. El riesgo de desarrollar demencia en estos individuos fue el doble (RR, 2.08 IC 95%, 1.59–2.73). Se encontró un riesgo mayor en individuos de 80 años y más (RR 2.44 IC 95%, 1.46–4.08), en los hombres (RR, 2.25 IC 95%, 1.46–3.49) y en sujetos con nivel educativo menor de 7 años. El estar bajo tratamiento con insulina incrementó el riesgo de demencia (RR, 2.83, IC 95%, 1.58–5.06). Las otras comorbilidades que aumentaron el riesgo de demencia en los pacientes diabéticos fueron la hipertensión (RR, 2.75, IC 95%, 1.86–4.06) y la depresión (RR, 3.78, 95% IC 2.37–6.04). Conclusión Los sujetos con diabetes mellitus tienen un riesgo mayor de desarrollar demencia, La baja escolaridad y otras comorbilidades altamente prevalentes en la población Mexicana contribuyen a la asociación diabetes-demencia.

  7. Getting food policy on the Mayoral table: a comparison of two election cycles in New York and London.

    PubMed

    Freudenberg, N; Atkinson, S

    2015-04-01

    Cities and Mayors are increasingly being recognized as important in shaping social policy and improving social well-being. And municipal food policies are increasingly important as a tool to reduce food insecurity and prevent diet-related chronic diseases. Thus city governments have a unique ability to improve local food environments. To realize this potential for improving urban food environments, nutrition advocates will need to find innovative approaches for influencing municipal food policy. This paper examines Mayoral elections as a vehicle to advance food policy. To explore this strategy, Mayoral elections in two cities, New York City (NYC) and London, during two recent cycles were compared. To gather evidence multiple sources were used including campaign documents, media and opinion polls as well as the authors' own observations as food policy observers and participants in the two cities. Mayoral governance differs between NYC and London, with the Mayor in NYC having greater powers of management and administration, whilst the London Mayor has a more strategic role and may need to also use 'influence'. Food policy and related issues did not feature strongly in the first election cycles in either city. However by the 2012 and 2013 elections food issues were definitely 'on the table' and featured in main candidates' campaign literature. These latter elections also saw the importance of food advocates coming together to form common alliances and place food issues higher on the municipal agenda. In this way, food policy has become part of the election dialogue in both cities and candidates are expected to consider food policy issues. This analysis leads to make observations which could guide advocates as to how to use Mayoral elections to raise policy objectives for the benefit of public health. PMID:25834929

    The Mw 7.2 El Mayor-Cucapah (EMC) earthquake ruptured a complex fault system in northern Baja California that was previously considered inactive. The Cerro Prieto Geothermal Field (CPGF), site of the world's second largest geothermal power plant, is located approximately 15 km to the northeast of the EMC hypocenter. We investigate whether anthropogenic fluid extraction at the CPGF caused a significant perturbation to the stress field in the EMC rupture zone. We use Advanced Land Observing Satellite interferometric synthetic aperture radar data to develop a laterally heterogeneous model of fluid extraction at the CPGF and estimate that this extraction generates positive Coulomb stressing rates of order 15 kPa/yr near the EMC hypocenter, a value which exceeds the local tectonic stressing rate. Although we cannot definitively conclude that production at the CPGF triggered the EMC earthquake, its influence on the local stress field is substantial and should not be neglected in local seismic hazard assessments.

    Large [moment magnitude (M(w)) ≥ 7] continental earthquakes often generate complex, multifault ruptures linked by enigmatic zones of distributed deformation. Here, we report the collection and results of a high-resolution (≥nine returns per square meter) airborne light detection and ranging (LIDAR) topographic survey of the 2010 M(w) 7.2 El Mayor-Cucapah earthquake that produced a 120-kilometer-long multifault rupture through northernmost Baja California, Mexico. This differential LIDAR survey completely captures an earthquake surface rupture in a sparsely vegetated region with pre-earthquake lower-resolution (5-meter-pixel) LIDAR data. The postevent survey reveals numerous surface ruptures, including previously undocumented blind faults within thick sediments of the Colorado River delta. Differential elevation changes show distributed, kilometer-scale bending strains as large as ~10(3) microstrains in response to slip along discontinuous faults cutting crystalline bedrock of the Sierra Cucapah.

    The surface rupture produced on April 4th of 2010 by the M 7.2 El Mayor-Cucapah Earthquake is an ideal target to be analyzed by remote sensing techniques. It produced over 100 km of scarps, with vertical and horizontal slip on the order of 2 to 3 m in scarcely vegetated, rugged terrain underlain by mostly igneous rocks. A 3D displacement field (DF) was calculated by matching pre- to post-event airborne LiDAR point clouds through the Iterative Closest Point (ICP) algorithm, which first segments the point clouds into discrete windows, and for each, iteratively converges on a rigid body transformation comprising a translation and a rotation that best aligns the pre- to post-event point clouds. After testing different window sizes, we used a square window 100m a side. The El Mayor-Cucapah LiDAR data sets present special challenges for the ICP technique. The point clouds differ considerably in point density, by ~1:700. This, and the lower precision of the pre-earthquake data, limit the accuracy of the DF results. Despite these issues, the vertical and East-West (E-W) components of the DF from ICP very clearly delineate the trace of the surface rupture, showing east-side down dextral-normal motion in agreement with field measurements and the focal mechanism reported for this event. A systematic error in the LiDAR instrument used for the pre-event survey caused severe distortion of the North-South (N-S) component of the LiDAR returns. After reprocessing the source pre-event point cloud in various ways to correct for the systematic error, a more plausible pattern for the N-S component was obtained for the DF. To have another perspective for the horizontal DF, a subpixel correlation analysis of optical satellite images (SPOT 2.5 m panchromatic images) before and after the earthquake, was performed using the COSI-Corr software. We combined the N-S component from this analysis with the E-W and vertical components of the ICP results, and present the analysis of the resulting

    Pollen data are presented from Mayor Island, Bay of Plenty. The island was important in prehistory as a source of obsidian (Seelenfreund, A., Bollong, C., 1989. The sourcing of New Zealand obsidian artefacts using energy dispersive XRF Spectroscopy. In: D. Sutton (Editor), Saying So Doesn't Make It So: Papers in honour of B. Foss Leach. New Zealand Archaeological Association Monograph, Wellington, pp. 168-189.) and holds a strategic location relative to the settlement of the North Island of New Zealand since it lies on possible arrival routes from Polynesia, and also relative to travel up and down the east coast of the North Island. The pollen data show that the island was generally forested between c. 3000 and c. 450 BP, when forest declined and the bracken fern Pteridium esculentum (and charcoal) increased. Before significant forest decline at 450 BP, which is consistent with Maori occupation at the time of the fortified settlements known as pa, there is evidence of other episodes of vegetation disturbance dating back to c. 2200 BP which may represent earlier visits by people.

    The high-resolution terrestrial LiDAR scans of northern Mexico obtained after the April 2010, Mw7.2 El Mayor-Cucapah earthquake (post-earthquake data), along with aerial LiDAR scans of the same area from before the earthquake (pre-earthquake data), make possible an accurate examination of the shifts in the region due to the event. We present methods for analyzing the various shifts throughout the area. We make two assumptions: (1) at a local level, excluding the area around the fault line, the features have minimal deformation, and (2) any feature was translated no more than five meters, with an optional change in orientation of no more than 15 degrees. We have developed an effective technique, where we iterate though all the points of the pre-earthquake data, using for each point a disc with a radius of 10 meters centered around each sample point, and define a feature based on all the points in this disc. Since the resolution of the pre-earthquake data is less than that of the post-earthquake data, it makes sense to define the features using pre-earthquake points. In the post-earthquake data set, we attempt to find the same feature by searching a ten-by-ten square meter grid centered at the same point as the feature from the pre-earthquake data set. Once a match has been determined, we draw a translation vector from the original position of the feature in the pre-earthquake data to the translated position of the feature in the post-earthquake data. As we draw one vector for each feature, we create a translation vector field that shows the movement caused by the earthquake.

  17. The Mayor of EarthCube: Cities as an Analogue for Governing Cyberinfrastructure

    Historical development of national and global infrastructure follows common paths with common imperatives. The nascent development may be led a by champion, innovator, or incubating organization. Once the infrastructure reaches a tipping point and adoption spreads rapidly, the organization and governance evolves in concert. Ultimately, no wide-spread infrastructure (from canals to highways to the electric grid to radio/television, or the Internet) operates with a single overarching governing body. The NSF EarthCube initiative is a prototype implementation of cyberinfrastructure, using the broad geoscience community as the testbed. Governance for EarthCube is emulating the pattern of other infrastructure, which we argue is a system of systems that can be described by organized complexity, emergent systems, and non-linear thermodynamics. As we consider governance cyberinfrastructure in the geosciences, we might look to cities as analogs: cities provide services such as fire, police, water, and trash collection. Cities issue permits and often oversee zoning, but much of what defines cities is outside the direct control of city government. Businesses choose whether to locate there, where to operate, and what to build. Residents make similar decisions. State and federal agencies make decisions or impose criteria that greatly affect cities, without necessarily getting agreement from them. City government must thus operate at multiple levels - providing oversight and management of city services, interaction with residents, businesses, and visitors, and dealing with actions and decisions made by independent entities over which they have little or no control. Cities have a range of organizational and management models, ranging from city managers, councils, and weak to strong mayors, some elected directly, some chosen from councils. The range and complexity of governance issues in building, operating, and sustaining cyberinfrastructure in the geosciences and beyond, rival

    Due to its location on a transtensional section of the Pacific-North American plate boundary, the Salton Trough is a region featuring large strike-slip earthquakes within a regime of shallow asthenosphere, high heat flow, and complex faulting, and so postseismic deformation there may feature enhanced viscoelastic relaxation and afterslip that is particularly detectable at the surface. The 2010 El Mayor-Cucapah earthquake was the largest shock in the Salton Trough since 1892 and occurred close to the US-Mexico border, and so the postseismic deformation recorded by the continuous GPS network of southern California provides an opportunity to study the rheology of this region. Three-year postseismic transients extracted from GPS displacement time-series show four key features: (1) 1-2 cm of cumulative uplift in the Imperial Valley and 1 cm of subsidence in the Peninsular Ranges, (2) relatively large cumulative horizontal displacements 150 km from the rupture in the Peninsular Ranges, (3) rapidly decaying horizontal displacement rates in the first few months after the earthquake in the Imperial Valley, and (4) sustained horizontal velocities, following the rapid early motions, that were still visibly ongoing 3 years after the earthquake. Kinematic inversions show that the cumulative 3-year postseismic displacement field can be well fit by afterslip on and below the coseismic rupture, though these solutions require afterslip with a total moment equivalent to at least a earthquake and higher slip magnitudes than those predicted by coseismic stress changes. Forward modeling shows that stress-driven afterslip and viscoelastic relaxation in various configurations within the lithosphere can reproduce the early and later horizontal velocities in the Imperial Valley, while Newtonian viscoelastic relaxation in the asthenosphere can reproduce the uplift in the Imperial Valley and the subsidence and large westward displacements in the Peninsular Ranges. We present two forward

  12. Seismological evidence and dynamic model of reverse rupture propagation during the 2010 M7.2 El Mayor Cucapah earthquake

    2011-12-01

    The 2010 El Mayor-Cucapah earthquake has produced some unique observations that exemplify the complexity of rupture dynamics. An eyewitness located near the fault when the rupture broke reported signatures of reverse surface rupture (rupture towards the South at a location North from the hypocenter). We report here on seismological evidence of this phenomenon and present dynamic rupture simulations that illustrate a possible mechanism. Reverse rupture propagation is not admissible in traditional source inversions, because of restrictive assumptions about the rupture kinematics adopted to reduce the non-uniqueness of the inverse problem. In contrast, source imaging by back-projection of dense array data is free from such assumptions. Recently, we have enhanced the array back-projection technique to achieve higher resolution on rupture evolution. We have also extended this approach to recordings at regional distance, despite the complexity of the regional Pn waveforms. We imaged the source of the El Mayor-Cucapah earthquake by back-projecting Pn waves recorded by the SIEDCAR array in New Mexico. Our analysis reveals a segment with reverse rupture propagation consistent with the eyewitness reports. Our simulations of dynamic earthquake rupture show that reverse rupture propagation can be caused by delayed rupture of a strong fault region with a negative along-strike gradient of strength excess. In this scenario the rupture front tunnels through (or surrounds) the strong area, then starts breaking the opposite, weaker end of the strong patch, inducing a reverse rupture front.

    531 imagens contidas no The International Halley Watch Atlas of Large-Scale Phenomena (Brandt et al., 1992) cobrindo o período de setembro de 1985 a julho de 1986 foram analisadas visando identificar, caracterizar as propriedades e correlacionar estruturas morfológicas da cauda de plasma do cometa P/Halley. A análise revelou 47 eventos de desconexão (DEs) (Niedner & Brandt, 1979; Jockers, 1985; Celnik et al., 1988; Delva et al., 1991). A análise completa de todas as imagens encontra-se publicada em Voelzke & Matsuura, 1998. A distribuição dos DEs na distância heliocêntrica apresenta um caráter bimodal possivelmente associado com a distribuição espacial das fronteiras de setor magnético do meio interplanetário. Os 47 DEs fotografados em 47 imagens distintas permitiram determinar 19 origens de DEs, ou seja, o instante em que supostamente o cometa cruzou a fronteira entre setores magnéticos do vento solar. Tais dados cometários foram comparados com dados do vento solar provenientes de medidas realizadas in situ pelas sondas IMP-8, ICE e PVO, que mediram a variação da velocidade do vento solar, da densidade e da pressão dinâmica durante o intervalo analisado. Os dados destas sondas espaciais em conjunto com os da sonda Vega 1 foram usados para determinar o tempo das passagens do lençol de corrente. Com base nos dados das sondas foram calculadas as coordenadas heliográficas retroativas do lençol de corrente na "superfície fonte" dos mapas sinóticos do campo magnético de Hoeksema, 1989. O cálculo retroativo é feito através de um modelo simples de expressão do vento solar com velocidade uniforme, sendo considerada a co-rotação da magnetosfera com o Sol. Este trabalho apresenta os resultados desta comparação e a análise cinemática da origem dos DEs, determinada sob a hipótese que o plasma desconectado de um dado DE afasta-se com velocidade constante do núcleo cometário (Voelzke & Matsuura, 1998) e compara esta análise com outras que

    2015-12-01

    The M 7.2 El Mayor - Cucapah earthquake occurred on 4 April 2010 in the northern part of Baja, Mexico. The rupture extended about 120 km from near the northern tip of the Gulf of California to the US - Mexican border south of the Elsinore fault zone. Most of the aftershocks occurred within days of the main event. On 14 June 2010 a M 5.7 late aftershock occurred 8 km southeast of Ocotillo, CA and is the largest aftershock in the sequence. The right-lateral event occurred in a cluster of aftershocks and was followed by its own aftershock sequence. UAVSAR data were collected for a swath covering the aftershock on 13 April, 2010 just after the El Mayor - Cucapah earthquake and before the earthquake on 21 October 2009. The line was reflown 1 July 2010 after the M 5.7 14 June 2010 aftershock. Data have been continued to be collected semi yearly to yearly since then. Repeat Pass Interferomety (RPI) products spanning the aftershock show the growth of a lineament that with an azimuth of 121.5° or a strike of -58.5°. The interferograms suggest that a stepover develops following the earthquake. The epicenter of the M 5.7 aftershock is proximal to the linear discontinuity in the postseismic interferogram and the mechanism of the event is consistent with slip on this stepover. Inversions for slip on the northeast linear structure that steps west of the mainshock rupture yield a moment magnitude ranging from 5.5 - 5.8, which is consistent with the magnitude of the aftershock. Slip occurs at a depth of 2-10 km on a steeply dipping fault.

    Surface fracturing (triggered slip) occurred in the central Salton Trough and to the southwest, in the Yuha Desert area—all in association with the 4 April 2010 (M7.2) El Mayor-Cucapah earthquake and its aftershocks. Triggered slip in the central Salton Trough occurred on the ‘frequent movers’: the southern San Andreas, Coyote Creek, Superstition Hills, and Imperial Faults, all of which have slipped in previous moderate to large, local and regional earthquakes in the past five decades. Other faults in the central Salton Trough that also slipped in 2010 include the Wienert Fault (southeastern section of the Superstition Hills Fault), the Kalin Fault (in the Brawley Seismic Zone), and the Brawley Fault Zone; triggered slip had not been reported on these faults in the past. Geologic measures of slip on faults in the central Salton Trough ranged from 1 to 18 mm, and everywhere was located where previous primary (tectonic) or triggered slip has occurred. Triggered slip in the Yuha Desert area occurred along at least two dozen faults, only some of which were known before the 4 April 2010 El Mayor-Cucapah earthquake. From east to northwest, slip occurred in seven general areas; 1) in the Northern Centinela Fault Zone (newly named), 2) along unnamed faults south of Pinto Wash, 3) along the Yuha Fault (newly named), 4) along both east and west branches of the Laguna Salada Fault, 5) along the Yuha Well Fault Zone (newly revised name), 6) along the Ocotillo Fault (newly named), and 7) along the southeastern-most section of the Elsinore Fault. Faults that slipped in the Yuha Desert area include northwest-trending right-lateral faults, northeast-trending left-lateral faults, and north-south faults, some of which had dominantly vertical slip. Triggered slip along the Ocotillo and Elsinore Faults occurred only in association with the 14 June 2010 (M5.7) aftershock, which also initiated slip along other faults near the town of Ocotillo. Triggered slip on faults in the Yuha

    The Colorado River Delta region of southern Imperial Valley, California, and Mexicali Valley, Baja California, is a tectonically dynamic area characterized by numerous active faults and frequent large seismic events. Significant earthquakes that have been accompanied by surface fault rupture and/or soil liquefaction occurred in this region in 1892 (M7.1), 1915 (M6.3; M7.1), 1930 (M5.7), 1940 (M6.9), 1950 (M5.4), 1957 (M5.2), 1968 (6.5), 1979 (6.4), 1980 (M6.1), 1981 (M5.8), and 1987 (M6.2; M6.8). Following this trend, the M7.2 El Mayor-Cucapah earthquake of April 4, 2010, ruptured approximately 120 kilometers along several known faults in Baja California. Liquefaction caused by the M7.2 El Mayor-Cucapah earthquake was widespread throughout the southern Imperial Valley but concentrated in the southwest corner of the valley, southwest of the city centers of Calexico and El Centro where ground motions were highest. Although there are few strong motion recordings in the very western part of the area, the recordings that do exist indicate that ground motions were on the order of 0.3 to 0.6g where the majority of liquefaction occurrences were found. More distant liquefaction occurrences, at Fites Road southwest of Brawley and along Rosita Canal northwest of Holtville were triggered where ground motions were about 0.2 g. Damage to roads was associated mainly with liquefaction of sandy river deposits beneath bridge approach fills, and in some cases liquefaction within the fills. Liquefaction damage to canal and drain levees was not always accompanied by vented sand, but the nature of the damage leads the authors to infer that liquefaction was involved in the majority of observed cases. Liquefaction-related damage to several public facilities - Calexico Waste Water Treatment Plant, Fig Lagoon levee system, and Sunbeam Lake Dam in particular - appears to be extensive. The cost to repair these facilities to prevent future liquefaction damage will likely be prohibitive. As

    The realization of national climate change commitments, as agreed through international negotiations, requires local action. However, data is still insufficient to make accurate statements about the scale of urban emissions (UNHABITAT, 2011). The need of comparable emission inventories at city level, including smaller cities, is widely recognized to develop evidence-based policies accounting for the relation between emissions and institutional, socio-economic and demographic characteristics at city level. This paper presents a collection of harmonized greenhouse gases (GHG) emission inventories (the "CoM sample 2013") at municipal level directly computed by the cities and towns that participate in the EU Covenant of Mayors initiative. This is the mainstream European movement of local and regional authorities who voluntarily commit to reduce GHG emissions by 20 % or more by 2020. The "CoM sample 2013" (http://edgar.jrc.ec.europa.eu/com/data/index.php?SECURE=123, doi:10.2904/EDGARcom2013) has been carefully checked to ensure its internal consistency and its congruity with respect to internationally accepted guide values for emission factors. Overall, it provides valuable data for the analysis of the heterogeneity of final energy consumption and greenhouse gas emissions of cities.

    We detect and precisely locate over 9500 aftershocks that occurred in the Yuha Desert region during a 2 month period following the 4 April 2010 Mw 7.2 El Mayor-Cucapah (EMC) earthquake. Events are relocated using a series of absolute and relative relocation procedures that include Hypoinverse, Velest, and hypoDD. Location errors are reduced to ~40 m horizontally and ~120 m vertically.Aftershock locations reveal a complex pattern of faulting with en echelon fault segments trending toward the northwest, approximately parallel to the North American-Pacific plate boundary and en echelon, conjugate features trending to the northeast. The relocated seismicity is highly correlated with published surface mapping of faults that experienced triggered surface slip in response to the EMC main shock. Aftershocks occurred between 2 km and 11 km depths, consistent with previous studies of seismogenic thickness in the region. Three-dimensional analysis reveals individual and intersecting fault planes that are limited in their along-strike length. These fault planes remain distinct structures at depth, indicative of conjugate faulting, and do not appear to coalesce onto a throughgoing fault segment. We observe a complex spatiotemporal migration of aftershocks, with seismicity that jumps between individual fault segments that are active for only a few days to weeks. Aftershock rates are roughly consistent with the expected earthquake production rates of Dieterich (1994). The conjugate pattern of faulting and nonuniform aftershock migration patterns suggest that strain in the Yuha Desert is being accommodated in a complex manner.

    Edge detection identifies seismic or aseismic fault motion, as demonstrated in repeat-pass inteferograms obtained by the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) program. But this identification, demonstrated in 2010, was not robust: for best results, it requires a flattened background image, interpolation into missing data (holes) and outliers, and background noise that is either sufficiently small or roughly white Gaussian. Proper treatment of missing data, bursting noise patches, and tiny noise differences at short distances apart from bursts are essential to creating an acceptably reliable method sensitive to small near-surface fractures. Clearly a robust method is needed for machine scanning of the thousands of UAVSAR repeat-pass interferograms for evidence of fault slip, landslides, and other local features: hand-crafted intervention will not do. Effective methods of identifying, removing and filling in bad pixels reveal significant features of surface fractures. A rich network of edges (probably fractures and subsidence) in difference images spanning the South Napa earthquake give way to a simple set of postseismically slipping faults. Coseismic El Mayor-Cucapah interferograms compared to post-seismic difference images show nearly disjoint patterns of surface fractures in California's Sonoran Desert; the combined pattern reveals a network of near-perpendicular, probably conjugate faults not mapped before the earthquake. The current algorithms for UAVSAR interferogram edge detections are shown to be effective in difficult environments, including agricultural (Napa, Imperial Valley) and difficult urban areas (Orange County.).

    Among the many preserved sound artefacts deposited in the offerings of the Aztec Templo Mayor are a set of ten tubular duct flutes made from clay, dating Late Postclassic Mesoamerica, 1350-1521 AD. The aerophones are completely painted in blue, and characterized by: (1) a short mouthpiece; (2) a framed aperture; (3) a tube with four fingerholes; and (4) an applicated mask with features of the Aztec rain god Tlaloc, basically three rings and a standardized relief structure of two clouds. While all measurements follow the same pattern, one particular organological distinction was made, as five flutes show an exit hole in the middle ring of the mask and five flutes are stopped. Thus, five instruments sound considerably higher, apart from the minimal pitch deviation of each specimen. Both the tonal capacity of each flute and the acoustics of several flutes played simultaneously were recorded and measured. A series of remarkable interference effects could be produced, which were strongly related to the ritual complex reflected in the offering. Taking in consideration the Aztec concept of music, it could be supposed that they were perceived as a principle of the song, or proper voice of Tlaloc.

    Triggered slip in the Yuha Desert area occurred along more than two dozen faults, only some of which were recognized before the April 4, 2010, El Mayor-Cucapah earthquake. From east to northwest, slip occurred in seven general areas: (1) in the Northern Centinela Fault Zone (newly named), (2) along unnamed faults south of Pinto Wash, (3) along the Yuha Fault (newly named), (4) along both east and west branches of the Laguna Salada Fault, (5) along the Yuha Well Fault Zone (newly revised name) and related faults between it and the Yuha Fault, (6) along the Ocotillo Fault (newly named) and related faults to the north and south, and (7) along the southeasternmost section of the Elsinore Fault. Faults that slipped in the Yuha Desert area include northwest-trending right-lateral faults, northeast-trending left-lateral faults, and north-south faults, some of which had dominantly vertical offset. Triggered slip along the Ocotillo and Elsinore Faults appears to have occurred only in association with the June 14, 2010 (Mw5.7), aftershock. This aftershock also resulted in slip along other faults near the town of Ocotillo. Triggered offset on faults in the Yuha Desert area was mostly less than 20 mm, with three significant exceptions, including slip of about 50–60 mm on the Yuha Fault, 40 mm on a fault south of Pinto Wash, and about 85 mm on the Ocotillo Fault. All triggered slips in the Yuha Desert area occurred along preexisting faults, whether previously recognized or not.

  4. Coseismic and Postseismic Deformation Due to the 2010 El Mayor-Cucapah Earthquake Detected by ALOS/PALSAR Data

    On April 4th, 2010, the Mw 7.2 El Mayor-Cucapah earthquake occurred in northeast Baja California, near the US-Mexico border. Since then, ALOS/PALSAR observed this region twenty times, which provides a rich data set to study the co- and post-seismic deformation. We first estimated the slip distribution and dip angle of the fault plane by inverting InSAR data with the method developed by Fukahata and Wright (2008). With this method, we can obtain the slip distribution on a plane fault and its dip angle simultaneously by minimizing the ABIC (Akaike's Bayesian Information Criterion). In southeastern area near the Gulf of California, we could recognize effects of liquefaction, so we did not use the data in such areas in the inversion. We assumed one sufficiently large rectangular plane fault and the strike is assumed to be 313 degrees from the north. After trials and errors, we restricted the search of the dip angle in a range of 30-90 degrees, dipping northeastward. The optimal dip angle was estimated 68 degrees, which is smaller than 82 degrees of the CMT solution (USGS). Right lateral strike slips with slight normal component were estimated, and the maximum slip of about 3m was obtained in the northwestern vicinity of the hypocenter. The total geodetic moment of our best-fitting model was in a good agreement with the seismic moment. In the postseismic period, we detected signals at two locations that can be attributed to postseismic deformation. First, we recognize some signals near the northwestern edge of the source fault in all the early postseismic interferograms (46 days after the earthquake) of both ascending and descending directions. In this area, the coseismic slip was estimated to be about 2m. We performed some forward calculations to confirm that this signal is not likely to be due to aftershocks. We computed the poroelastic deformation based on our coseismic slip model and found that the observed signal has the opposite sense. Moreover, a 2.5 dimensional

    Objetivos. Nos propusimos determinar el grado de preparación frente a los desastres naturales de los adultos mayores en los Estados Unidos y evaluar los factores que pueden afectar negativamente la salud y la seguridad durante este tipo de incidentes. Métodos. Obtuvimos una muestra de adultos de 50 años en adelante (n = 1 304) de la encuesta del 2010 del Estudio de la Salud y la Jubilación (HRS por su sigla en inglés). La encuesta recogió datos sobre las características demográficas generales, el estado de discapacidad o las limitaciones funcionales, y también sobre factores y comportamientos relacionados con la preparación frente a los desastres. Calculamos una puntuación global de preparación mediante indicadores individuales a fin de evaluar el grado de preparación general. Resultados. La media de la edad de los participantes (n = 1 304) fue de 70 años (desviación estándar [DE] = 9,3). Solo 34,3% informaron que habían participado en un programa formativo o que habían leído materiales sobre la preparación para los desastres. Casi 15% indicaron que usaban dispositivos médicos eléctricos que podían correr riesgo de no funcionar si se interrumpiera el suministro eléctrico. La puntuación de preparación indicó que la edad más avanzada, la discapacidad física y el menor nivel de escolaridad y de ingresos se asociaban independiente y significativamente a un grado de preparación general inferior. Conclusiones. A pesar de la mayor vulnerabilidad ante los desastres y del número cada vez mayor de adultos mayores en los Estados Unidos, muchos de los problemas sustanciales que encontramos son remediables y requieren atención en los sectores de la sociedad dedicados a la atención clínica, a la salud pública y al manejo de situaciones de emergencia.

    A method is outlined by means of which it is possible to estimate high-resolution vertical displacements due to an earthquake even in the case where high-resolution topography is lacking before the earthquake. This result can be achieved by combining a highly accurate, post-event digital elevation model (DEM), for example lidar, with archived satellite imagery. The method is illustrated by calculating vertical displacements for the 2010 El Mayor-Cucapah earthquake. For this earthquake, there are both pre- and post-event lidar DEMs from which vertical displacements may also be estimated after correcting for the lateral advection of topography due to horizontal displacements. A comparison between the two means of deriving vertical displacements shows generally good agreement, with the displacements obtained using satellite imagery performing better in high relief areas. As a result of this property, we are able to trace the vertical offsets due to the El Mayor-Cucapah earthquake as the rupture jumped from the Pescadores fault to the Borrego fault in propagating through the high relief of the Sierra Cucapah.

    Fault dips are usually measured from outcrops in the field or inferred through geodetic or seismological modeling. Here we apply the classic structural geology approach of calculating dip from a fault's 3-D surface trace using recent, high-resolution topography. A test study applied to the 2010 El Mayor-Cucapah earthquake shows very good agreement between our results and those previously determined from field measurements. To obtain a reliable estimate, a fault segment ≥120 m long with a topographic variation ≥15 m is suggested. We then applied this method to the 2013 Balochistan earthquake, getting dips similar to previous estimates. Our dip estimates show a switch from north to south dipping at the southern end of the main trace, which appears to be a response to local extension within a stepover. We suggest that this previously unidentified geometrical complexity may act as the endpoint of earthquake ruptures for the southern end of the Hoshab fault.

    4 April 2010 M 7.2 El Mayor-Cucapah earthquake that occurred in Baja California, Mexico and terminated near the U.S. Mexican border caused slip on the Imperial, Superstition Hills, and East Elmore Ranch Faults. The pattern of slip was observed using radar interferometry from NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument collected on 20-21 October 2009 and 12-13 April 2010. Right-lateral slip of 36 ± 9 and 14 ± 2 mm occurred on the Imperial and Superstition Hills Faults, respectively. Left-lateral slip of 9 ± 2 mm occurred on the East Elmore Ranch Fault. The widths of the zones of displacement increase northward suggesting successively more buried fault motion to the north. The observations show a decreasing pattern of slip northward on a series of faults in the Salton Trough stepping between the El Mayor-Cucapah rupture and San Andreas Fault. Most of the motion occurred at the time of the M 7.2 earthquake and the UAVSAR observations are consistent with field, creepmeter, GPS, and Envisat observations. An additional 28 ± 1 mm of slip at the southern end of the Imperial Fault over a <1 km wide zone was observed over a 1 day span a week after the earthquake suggesting that the fault continued to slip at depth following the mainshock. The total moment release on the three faults is 2.3 × 1023-1.2 × 1024 dyne cm equivalent to a moment magnitude release of 4.9-5.3, assuming shallow slip depths ranging from 1 to 5 km.

    Radar interferometry (InSAR), field measurements and creepmeters reveal surface slip on multiple faults in the Imperial Valley triggered by the main shock of the 4 April 2010 El Mayor-Cucapah Mw 7.2 earthquake. Co-seismic offsets occurred on the San Andreas, Superstition Hills, Imperial, Elmore Ranch, Wienert, Coyote Creek, Elsinore, Yuha, and several minor faults near the town of Ocotillo at the northern end of the mainshock rupture. We documented right-lateral slip (<40 mm) on northwest-striking faults and left-lateral slip (<40 mm) on southwest-striking faults. Slip occurred on 15-km- and 20-km-long segments of the San Andreas Fault in the Mecca Hills (≤50 mm) and Durmid Hill (≤10 mm) respectively, and on 25 km of the Superstition Hills Fault (≤37 mm). Field measurements of slip on the Superstition Hills Fault agree with InSAR and creepmeter measurements to within a few millimeters. Dislocation models of the InSAR data from the Superstition Hills Fault confirm that creep in this sequence, as in previous slip events, is confined to shallow depths (<3 km).

    In this manuscript, we introduce a framework for developing earthquake forecasts using Virtual Quake (VQ), the generalized successor to the perhaps better known Virtual California (VC) earthquake simulator. We discuss the basic merits and mechanics of the simulator, and we present several statistics of interest for earthquake forecasting. We also show that, though the system as a whole (in aggregate) behaves quite randomly, (simulated) earthquake sequences limited to specific fault sections exhibit measurable predictability in the form of increasing seismicity precursory to large m > 7 earthquakes. In order to quantify this, we develop an alert-based forecasting metric, and show that it exhibits significant information gain compared to random forecasts. We also discuss the long-standing question of activation versus quiescent type earthquake triggering. We show that VQ exhibits both behaviours separately for independent fault sections; some fault sections exhibit activation type triggering, while others are better characterized by quiescent type triggering. We discuss these aspects of VQ specifically with respect to faults in the Salton Basin and near the El Mayor-Cucapah region in southern California, USA and northern Baja California Norte, Mexico.

    The M7.2 El Mayor-Cucapah earthquake of April 4, 2010 in Mexico’s Baja California caused extensive damage to the agricultural area of Mexicali Valley. The damage included wide-spread liquefaction and lateral spreading which destroyed or damaged irrigation canals. Without water, wheat, alfalfa, and other crops were lost. Fields were cut by fissures and partially buried by massive sand blows. Regional tilting from the earthquake was a serious issue for the gravity-controlled irrigation system. Ruptured canals and groundwater from sand blows flooded fields, roads, and towns. Flooding further damaged crops and brought contamination with it. Fissures and scarps through farm communities cracked buildings; ruptured water, sewer, and other pipelines; and made roads temporarily difficult to pass. Economically, farmers, seasonal farm workers, and agricultural suppliers were affected; reducing their ability to consume the goods and services of businesses unrelated to agriculture. Similar damage was observed in earlier earthquakes over the past 100 years. Society quickly forgets how the earth responds to strong shaking. We hope to provide a vivid portrait of this agricultural disaster so that other farming communities prone to strong seismic shaking may visualize what can happen from their own inevitable future earthquake. Fissure and sand blows southeast of Cucapah, Baja California, April 16, 2010. Heavily damaged irrigation canal northwest of Zacamoto, Baja California, April 15, 2010.

    Whether static or dynamic stress changes play the most important role in triggering earthquakes in the near field is still in debate. Here, we examine the seismicity rate changes in southern California following the 2010 Mw 7.2 El Mayor-Cucapah earthquake. We focus on the Salton Sea Geothermal Field (SSGF) and the San Jacinto Fault Zone (SJFZ) because of high-sensitivity continuous borehole recordings and ample background seismicity. A significant increase in seismic activity is found in both study regions immediately following the main shock. However, near the SSGF where the static Coulomb stress decreased, the seismicity rate dropped below the pre-main-shock rate after ˜1 month. In comparison, along the SJFZ with an increase in the static Coulomb stress, the seismicity rate remained higher than the background rate with several moderate-size earthquakes occurring in the subsequent months. While we cannot completely rule out other mechanisms, these observations are best consistent with a widespread increase in seismicity from dynamic stress changes immediately after the main shock, and longer term seismicity rate changes from static stress changes. Our observation, together with other recent studies, suggests that both static and dynamic stress changes are important in triggering near-field earthquakes, but their affected regions and timescales are different.

    El Mayor-Cucapah earthquake occurred on 4 April 2010 in northeastern Baja California just south of the U.S.-Mexico border. The earthquake ruptured several previously mapped faults, as well as some unidentified ones, including the Pescadores, Borrego, Paso Inferior and Paso Superior faults in the Sierra Cucapah, and the Indiviso fault in the Mexicali Valley and Colorado River Delta.We conducted several Global Positioning System (GPS) campaign surveys of preexisting and newly established benchmarks within 30 km of the earthquake rupture. Most of the benchmarks were occupied within days after the earthquake, allowing us to capture the very early postseismic transient motions. The GPS data show postseismic displacements in the same direction as the coseismic displacements; time series indicate a gradual decay in postseismic velocities with characteristic time scales of 66 ± 9 days and 20 ± 3 days, assuming exponential and logarithmic decay, respectively. We also analyzed interferometric synthetic aperture radar (InSAR) data from the Envisat and ALOS satellites. The main deformation features seen in the line-of-sight displacement maps indicate subsidence concentrated in the southern and northern parts of the main rupture, in particular at the Indiviso fault, at the Laguna Salada basin, and at the Paso Superior fault. We show that the near-field GPS and InSAR observations over a time period of 5 months after the earthquake can be explained by a combination of afterslip, fault zone contraction, and a possible minor contribution of poroelastic rebound. Far-field data require an additional mechanism, most likely viscoelastic relaxation in the ductile substrate.

    High-resolution surface topography is valuable for studying coseismic fault zone deformation and fault geometry. It enables us to measure three-dimensional surface displacements in earthquakes, as shown in recent studies that used light detection and ranging (lidar) to determine coseismic motion. However, the applicability of lidar is limited by its relatively high cost and low availability. In this study, we use the 2010 El Mayor-Cucapah earthquake to demonstrate the capability of Pleiades stereo imagery to measure coseismic vertical ground displacement. We acquired post-earthquake Pleiades tristereo imagery from backward, near-nadir, and forward orientations for a 45 km × 7 km portion of the epicentral area. One meter resolution digital elevation models (DEMs) were produced with the four different combinations of incidence angles and compared to the post-earthquake lidar DEM. Elevations from tristereo have slightly (˜15%) smaller uncertainties than bistereo as the tristereo DEM incorporates more observations. Elevation differences between the Pleiades and post-earthquake lidar DEMs show that the vertical accuracy of the Pleiades DEMs is ˜0.3 m. By differencing the Pleiades DEM and the pre-earthquake, 5 m resolution lidar DEM, we mapped meter and submeter offsets along the faults obtaining results comparable to a previous study that differenced the two lidar DEMs. This is the first case study of assessing very high resolution (VHR) satellite stereo imagery to determine submeter vertical ground displacement in an earthquake. By extension, we expect it to be possible to measure submeter vertical offsets occurring in earthquakes using pre-earthquake and post-earthquake VHR stereo imagery.

    The Mw 7.2 El Mayor-Cucapah (EMC) earthquake ruptured a ~120 km long series of faults striking northwest from the Gulf of California to the Sierra Cucapah. Five years after the EMC event, a dense network of GPS stations in southern California and a sparse array of sites installed after the earthquake in northern Mexico measure ongoing surface deformation as coseismic stresses relax. We use 3D finite element models of seismically inferred crustal and mantle structure with earthquake slip constrained by GPS, InSAR range change and SAR and SPOT image sub-pixel offset measurements to infer the rheologic structure of the region. Model complexity, including 3D Moho structure and distinct geologic regions such as the Peninsular Ranges and Salton Trough, enable us to explore vertical and lateral heterogeneities of crustal and mantle rheology. We find that postseismic displacements can be explained by relaxation of a laterally varying, stratified rheologic structure controlled by temperature and crustal thickness. In the Salton Trough region, particularly large postseismic displacements require a relatively weak mantle column that weakens with depth, consistent with a strong but thin (22 km thick) crust and high regional temperatures. In contrast, beneath the neighboring Peninsular Ranges a strong, thick (up to 35 km) crust and cooler temperatures lead to a rheologically stronger mantle column. Thus, we find that the inferred rheologic structure corresponds with observed seismic structure and thermal variations. Significant afterslip is not required to explain postseismic displacements, but cannot be ruled out. Combined with isochemical phase diagrams, our results enable us to go beyond rheologic structure and infer some basic properties about the regional mantle, including composition, water content, and the degree of partial melting.

Far-field data require an additional mechanism, most likely viscoelastic relaxation in the ductile substrate.

    The Mw 7.2 El Mayor-Cucapah earthquake (EMCE) of 4 April 2010 generated a ~110 km long, NW-SE trending rupture, with normal and right-lateral slip in the order of 2-3m in the Sierra Cucapah, the northern half, where the surface rupture has the most outstanding expression. Vertical and horizontal surface displacements produced by the EMCE have been addressed separately by other authors with a variety of aerial and satellite remote sensing techniques. Slip variation along fault and post-seismic scarp erosion and diffusion have been estimated in other studies using terrestrial LiDAR (TLS) on segments of the rupture. To complement these other studies, we computed the 3D deformation field by comparing pre- to post-event point clouds from aerial LiDAR surveys. The pre-event LiDAR with lower point density (0.013-0.033 pts m-2) required filtering and post-processing before comparing with the denser (9-18 pts m-2) more accurate post event dataset. The 3-dimensional surface displacement field was determined using an adaptation of the Iterative Closest Point (ICP) algorithm, implemented in the open source Point Cloud Library (PCL). The LiDAR datasets are first split into a grid of windows, and for each one, ICP iteratively converges on the rigid body transformation (comprising a translation and a rotation) that best aligns the pre- to post-event points. Testing on synthetic datasets perturbed with displacements of known magnitude showed that windows with dimensions of 100-200m gave the best results for datasets with these densities. Here we present the deformation field with detailed displacements in segments of the surface rupture where its expression was recognized by ICP from the point cloud matching, mainly the scarcely vegetated Sierra Cucapah with the Borrego and Paso Superior fault segments the most outstanding, where we are able to compare our results with values measured in the field and results from TLS reported in other works.

    We systematically mapped (scales >1:500) the surface rupture of the 4 April 2010 Mw 7.2 El Mayor-Cucapah earthquake through Sierra Cucapah to understand how faults with similar structural and lithologic characteristics control rupture zone fabric, which is here defined by the thickness, distribution and internal configuration of shearing in a rupture zone. Fault zone architecture and master fault dip showed the strongest controls on rupture zone fabric. Highly localized slip was observed along simple narrow fault cores (<20 m), whereas wide cores (>>50 m) composed of multiple zones of high shear strain had wider and more complex rupture zones that generally lacked principal-displacement scarps. Rupture zone thickness also increases systematically with decreasing fault zone dip. We observed that coseismic slip along faults that dip >40° was mostly confined to the fault core, whereas faults that dip as low as 20° had surface rupture entirely developed entirely outside of the fault zone. The lack of large off-fault strain along faults dipping >40° is contrary to predictions by dynamic stress modeling (e.g., Ma, 2009). We show that static tectonic loading, which varies significantly with fault orientation, has a significant effect not only on rupture zone fabric but also on the evolution of fault zone architecture in this transtensional setting. Rupture zones in undeformed alluvium are dominated by secondary fractures associated with fault-tip propagation, and arrays of fault scarps become wider and more complex with oblique slip compared to pure normal dip-slip or pure strike-slip. Field relations show that as magnitude of coseismic slip increases from 0 to 60 cm, the linkages between kinematically distinct fracture sets increases systematically to the point of forming a through going principal scarp, which is contrary to many analogue models (e.g., Tchalencko, 1970; Naylor et al., 1995) Our data indicate that secondary faults and penetrative off-fault strain

    Very high-resolution (VHR) imagery can in principle measure surface topography with decimetric precision. The question is how well 3D mapping based on VHR stereo imagery is capable of capturing sub-metric height changes occurring in an earthquake, particularly those in remote areas? The aim of this study is to assess the capability of the Pleiades satellites to determine such height changes. We acquired Pleiades stereo imagery with backward (B), near-nadir (N) and forward (F) orientations over a 40 km × 5 km area in Baja California, Mexico, part of the epicentral area of the 2010 Mw 7.2 El Mayor-Cucapah earthquake. Coverage was chosen to coincide with the post-seismic LiDAR digital elevation model (DEM) for the area. DEMs have been produced with four different combinations of incidence angles (B-N, N-F, B-F and B-N-F). The raw point cloud has the lowest average density of ~0.7 points/m2 for B-F, ~1.0 points/m2 for B-N and N-F, and the greatest average density of ~3 points/m2 for tri-stereo (B-N-F). Compared to the post-earthquake LiDAR DEM, the Pleiades DEMs have a mean error of 1 m to 4 m, with a standard deviation of 0.5 m to 0.7 m. A series of topographic profiles from the Pleiades DEMs across the earthquake rupture were used to measure vertical offsets. These profiles show that the Pleiades DEM is capable of capturing vertical offsets of ~0.5 m. The measurements of vertical offsets from tri-stereo have smaller uncertainties than bi-stereo; this suggests that the tri-stereo DEM incorporating redundant observations is more robust and reliable. By differencing the 1-m tri-stereo Pleiades DEM and the pre-earthquake, lower-resolution (5-m) LiDAR DEM, we mapped metre and sub-metre offsets along the faults obtaining results comparable to a previous study that differenced the two LiDAR DEMs (Fig. 1). By extension, we expect it to be possible in similar settings to measure sub-metre vertical offsets occurring in earthquakes using pre- and post-event Pleiades stereo

    Pore pressure built up during an earthquake and the hazard associated with soil liquefaction present a major challenge for our society, as was dramatically displayed during the 2011 Higashi Nihon Daishinsai (Tohoku-oki, Japan) earthquake. Currently, there is a consensus among scientists that a better assessment of the risk associated with liquefaction requires a better understanding of the coupling between pore pressure time histories and ground motion time histories. Specifically, there is a basic need to investigate the coupling as a function of the frequency content of the ground motion. The 2010 El Mayor-Cucapah (Baja California) earthquake (M 7.2) provides a remarkable opportunity to undertake such an investigation and lay the basis to model the coupling. The event was well recorded at the NEES@UCSB Wildlife station located 110 km from the hypocenter. The station is equipped with three-component strong-motion accelerometers at the surface and in boreholes at various depths and with pore pressure transducers located in a saturated, liquefiable layer. The recorded pore pressure and ground motion time histories are both characterized by a frequency content that is a function of time. A wavelet representation is a natural approach to investigate non-stationary time histories. To study the coupling between two signals we use the following procedure: We first compute the wavelet coefficients associated with the two signals. Then we compute the correlation between the wavelet coefficients of the two signals as a function of the frequency. Correlation coefficients provide information about the degree of linear dependence between the two signals. To account for the presence of multiplicative constants relating the wavelet coefficients of the first signal to the wavelet coefficients of the second signal, we compare the square norm of the wavelet coefficients of the two signals for the available frequency range. Additionally, investigating the distribution of the square

    Recent studies indicate that the passage of seismic waves from large earthquakes are able to trigger small earthquakes and tremor at regional distances. These small events may be detected by applying a high-pass filter to seismograms to remove the much larger ground motion amplitudes from the large distant earthquake. Our interests are in examining the local triggering of earthquakes and tremor throughout the West Coast of North America from the magnitude 7.2 El Mayor-Cucapah 2010 earthquake and the magnitude 6.8 Northern California, March 10, 2014 earthquake, just north of the Mendocino Triple Junction. We will present the results of the analysis of waveform data from hundreds of seismometers throughout Southern California, Northern California, Oregon, Washington, as well as some stations bordering these states. Our preliminary results suggest that triggering of local earthquakes and tremor occurred for both earthquakes. In the case of the records of the Southern California stations for the El Mayor Cucapah 2010 earthquake, 27 stations showed triggering near the seismic station. 13 of these stations are located in or near known geothermal areas, while others were located along active faults and one offshore. While conducting this study, we detected an instrumental noise signal present in 63 of the Southern California seismograms for the El Mayor-Cucapah earthquake. Initially, the signal looked like a typical triggered event, yet with further investigation we found its likely cause to be instrumental noise. We plan to relate our observations of triggered seismicity and tremor to the tectonic environment to test the hypothesis that triggering and tremor most commonly occurs in volcanic and geothermal areas.

    Aftershocks from the El Mayor-Cucapah (EMC), MW7.2, April 4, 2010, Baja California, Mexico, earthquake, were recorded over two months by a 31 station local array (Reftek RT130 seismographs loaned from IRIS-PASSCAL), complemented by regional data from SCSN, and CICESE. The resulting data base includes 518 aftershocks with ML ≥ 3.0, plus 181 smaller events. Reliable hypocenters were determined using HYPODD and a velocity structure determined from refraction data for a mesa located to the west of the Mexicali-Imperial Valley. Aftershock hypocenters show that the El Mayor-Cucapah earthquake was a multiple event comprising two or three different ruptures of which the last one constituted the main event. The main event rupture, which extends in a roughly N45°W direction, is complex with well-defined segments having different characteristics. The main event central segment, located close to the first event epicenter is roughly vertical, the northwest segment dips ~68°NE, while the two southeast segments dip ~60°SW and ~52°SW, respectively, which agrees with results of previous studies based on teleseismic long periods and on GPS-INSAR. All main rupture aftershock hypocenters have depths above 10-11km and, except for the central segment, they delineate the edges of zones with largest coseismic displacement. The two southern segments show seismicity concentrated below 5km and 3.5km, respectively; the paucity of shallow seismicity may be caused by the thick layer of non-consolidated sediments in this region. The ruptures delineated by aftershocks in the southern regions correspond to the Indiviso fault, unidentified until the occurrence of the EMC earthquake. The first event was relocated together with the aftershocks; the epicenter lies slightly westwards of published locations, but it definitely does not lie on, or close to, the main rupture. The focal mechanism of the first event, based on first arrival polarities, is predominantly strike-slip; the focal plane

    The 4 April 2010 Mw 7.2 El Mayor-Cucapah (EMC) earthquake provides the best opportunity to date to study the lithospheric response to a large (>M6) magnitude earthquake in the Salton Trough region through analysis of Global Positioning System (GPS) data. In conjunction with the EarthScope Plate Boundary Observatory (PBO), we installed six new continuous GPS stations in the months following the EMC earthquake to increase station coverage in the epicentral region of northern Baja California, Mexico. We modeled the pre-EMC deformation field using available campaign and continuous GPS data for southern California and northern Baja California and inferred a pre-EMC secular rate at each new station location. Through direct comparison of the pre- and post-EMC secular rates, we calculate long-term changes associated with viscoelastic relaxation in the Salton Trough region. We fit these velocity changes using numerical models employing an elastic upper crustal layer underlain by a viscoelastic lower crustal layer and a mantle half-space. Forward models that produce the smallest weighted sum of squared residuals have an upper mantle viscosity in the range 4-6 × 1018 Pa s and a less well-resolved lower crustal viscosity in the range 2 × 1019 to 1 × 1022 Pa s. A high-viscosity lower crust, despite high heat flow in the Salton Trough region, is inconsistent with felsic composition and might suggest accretion of mafic lower crust associated with crustal spreading obscured by thick sedimentary cover.

    El objetivo principal del artículo es estudiar la asociación entre la percepción subjetiva sobre la situación económica propia y una serie de medidas objetivas de bienestar socioeconómico –fuentes de ingresos, tenencia de vivienda, nivel educativo y transferencias familiares informales de dinero- entre adultos mayores de dos países Latinoamericanos: México y Costa Rica. Los datos se obtienen de las primeras rondas de dos encuestas sobre envejecimiento: CRELES para Costa Rica y ENASEM para México. La variable dependiente más importante se obtiene de las respuestas a las pregunta “¿Cómo califica su situación económica actual?” en Costa Rica y “¿Diría usted que su situación económica es…?” en México. Para ambas encuestas, las respuestas se codificaron en forma binaria; el código 0 representa las categorías Excelente, Muy buena y Buena, y el código 1 representa a las categorías Regular y Mala. Se encontró que el ingreso por jubilación es un importante determinante de la percepción de bienestar en ambos países. En Costa Rica, el ingreso del cónyuge y la tenencia de vivienda son importantes predictores de la percepción de bienestar, mientras que en México, los ingresos por transferencias están fuertemente asociados con dicha percepción.

  10. Testing long-period ground-motion simulations of scenario earthquakes using the Mw 7.2 El Mayor-Cucapah mainshock: Evaluation of finite-fault rupture characterization and 3D seismic velocity models

    Graves, Robert W.; Aagaard, Brad T.

    2011-01-01

    Using a suite of five hypothetical finite-fault rupture models, we test the ability of long-period (T>2.0 s) ground-motion simulations of scenario earthquakes to produce waveforms throughout southern California consistent with those recorded during the 4 April 2010 Mw 7.2 El Mayor-Cucapah earthquake. The hypothetical ruptures are generated using the methodology proposed by Graves and Pitarka (2010) and require, as inputs, only a general description of the fault location and geometry, event magnitude, and hypocenter, as would be done for a scenario event. For each rupture model, two Southern California Earthquake Center three-dimensional community seismic velocity models (CVM-4m and CVM-H62) are used, resulting in a total of 10 ground-motion simulations, which we compare with recorded ground motions. While the details of the motions vary across the simulations, the median levels match the observed peak ground velocities reasonably well, with the standard deviation of the residuals generally within 50% of the median. Simulations with the CVM-4m model yield somewhat lower variance than those with the CVM-H62 model. Both models tend to overpredict motions in the San Diego region and underpredict motions in the Mojave desert. Within the greater Los Angeles basin, the CVM-4m model generally matches the level of observed motions, whereas the CVM-H62 model tends to overpredict the motions, particularly in the southern portion of the basin. The variance in the peak velocity residuals is lowest for a rupture that has significant shallow slip (<5 km depth), whereas the variance in the residuals is greatest for ruptures with large asperities below 10 km depth. Overall, these results are encouraging and provide confidence in the predictive capabilities of the simulation methodology, while also suggesting some regions in which the seismic velocity models may need improvement.

    Following the 4 April 2010 M7.2 El Mayor-Cucapah earthquake, teams from UC Riverside, UC Santa Barbara, and San Diego State University installed an array of 8 temporary seismometers in the Yuha Desert area north of the Mexican border. This temporary array complemented the existing network stations and continuously recorded data from the aftershock sequence from 6 April through 14 June 2010. SCSN and the temporary aftershock array data will be used to study several aspects of fault structure and behavior, including precise relocation of the aftershock sequence. While the mainshock sequence ruptured multiple fault strands west of the Cerro Prieto fault, and south of the Sierra Cucapah Range, the aftershocks are densely clustered in three areas. The largest cluster is located to the northwest of the mainshock, in an area with no previously mapped faults. By relocating aftershocks, we hope to illuminate the network of faults that extend from the Laguna Salada fault in Mexico to its northern extension towards the Elsinore and San Jacinto faults. Right-lateral displacements up to 2 cm were identified on several right- and left-lateral fault segments by the USGS/CGS geologists in the area south of Hwy 98, and into the Pinto Wash (Treiman et al., personal communication, 2010). We relocate aftershocks within a 20 km by 14 km region containing 1 network and 8 temporary stations. Within this region over 4,000 aftershocks are in the SCEDC catalog from 6 April to 14 June 2010, during the time the temporary network was installed. The P and S wave arrival times for both the network and temporary stations were manually picked for each of these events. We compute the double difference hypocenter locations using the picked phase arrivals and waveform cross-correlations in the hypocenter relocation program, hypoDD (Waldhauser & Ellsworth 2000). In the event relocation, we used the velocity profile for the Imperial Valley from the SCEC Unified Velocity Model (Version 4). Future work

  12. A New Ensemble-Based Method for Assessing Uncertainties and Parameter Tradeoffs in Complex Models of Postseismic Deformation: Application to the 2010 M=7.2 El Mayor-Cucapah Earthquake

    2014-12-01

    The 2010 M=7.2 El Mayor-Cucapah earthquake occurred in the Salton Trough, a region of thinned lithosphere and high heat flow, and the postseismic deformation following this earthquake presents a unique opportunity to study the rheology of extensional environments and the mechanics of ductile flow within and beneath the lithosphere. Previous work [Rollins et al, in prep.] revealed that GPS timeseries of surface displacement following the earthquake were well fit to a coupled model simulating stress-driven afterslip on the deep extension of the coseismic rupture, Newtonian viscoelastic relaxation in a low-viscosity zone in the lower crust of the Salton Trough aligned with areas of high heat flow, and Newtonian viscoelastic relaxation in a three-dimensional asthenosphere with geometry matching that of the regional lithosphere-asthenosphere boundary inferred from receiver functions. Extending the success of this model to a robust interpretation of the mechanics of deformation at depth requires a better understanding of uncertainties and trade-offs between parameters (depth of the brittle-ductile transition, viscosities of the lower crust and asthenosphere, geometry of viscosity anomalies in the Salton Trough, frictional parameters of the possible downdip extensions of the coseismic rupture, and correlations among these parameters). We will show results from recent work that uses a newly developed method to efficiently explore this model space in a Bayesian sense. The method employs the Neighborhood Algorithm of Sambridge [1999], which makes use of Voronoi cells to optimize the search in the model space, samples regions that contains models of acceptable data fit, and extracts robust information from the ensemble of models obtained. The method is particularly well suited to identify a class of models that fit geodetic data approximately equally well, allowing us to present and discuss a range of possible deformation mechanisms. This method can be applied to any study of

    2010-12-01

    The El Mayor-Cucapah earthquake (Mw = 7.2) was the largest earthquake to occur in northeastern Baja California since February 1892, when an earthquake of slightly lower magnitude occurred at the northwestern end of the Laguna Salada fault. This event, with epicenter located ~ 40 km south of the city of Mexicali, occurred on April 4, 2010 at 15:40 local time or 22:40 UTC. Thirteen strong motion stations of a network operated by CICESE in Baja California were triggered by the main shock. Those stations are located at distances of 12 to 140 km from the epicenter. Six of them are located on sediments of the Mexicali Valley, at less than 40 km from the epicenter; the other seven stations recorded at larger distances, on granitic rocks of the peninsular ranges of Baja California. In this study, we analyze the digital accelerograms produced by the main shock and by most of the larger aftershocks. At first, the P-wave arrival times measured on the accelerograms were combined with time readings from the closer-to-the-source weak-motion stations to relocate the hypocenters. With this, we attempted to improve the hypocenter locations obtained on the basis of more regional data sets. Due to lack of station coverage to the south of the main-shock’s epicenter, this task was particularly important for those aftershocks occurring along the SE extension of the ruptured area. Our located hypocenters had smaller location errors and provide a better insight about the extent of the main-shock rupture to southeast. Concerning the strong motion data, we noted that on sediments the recorded peak ground accelerations (PGA) varied from 0.148 to 0.815 g, while on the rock sites the PGA were in the range 0.013 to 0.074 g. The largest peak acceleration recorded was observed on the vertical component of the MDO station, sited on sediments. For ground velocity and displacement, the peak values from sedimentary sites are between 14 and 61 cm/sec and 9 and 52 cm, respectively. In such instances

  14. Late Quaternary Range-Front Fault Scarps in the Western Sierra El Mayor, Baja California, Mexico: A Geomorphologic Expression of Slip Across an Active Low-Angle Normal Fault

    2006-12-01

    The western margin of the Sierra El Mayor (SEM), in northeastern Baja California, is controlled by an active, top-to-the-west, low-angle normal fault named the Canada David detachment (CDD) that accommodates part of the extensional component of shearing between the Pacific and North American plates. The CDD has a length of 60 km and shows a curvilinear trace with two major antiformal and synformal megamullion pairs. Late Quaternary slip has produced a broad array of Quaternary scarps cutting alluvial fans along nearly the entire length of the CDD. Detailed mapping reveals eight regional strath terraces distinguished by surface weathering characteristics, soil profile development and relative elevation. Relative height between terraces increases in domains where the CDD and basin deposits are being uplifted due to either the basinward migration of faulting (e.g., rolling hinge) or flexural uplift in antiformal megamullion domains. Linear diffusion analysis of 46 synthetic fault scarps, with a calculated angle of repose Θo = 28.75°, reveal fault scarp domains exhibiting both multi-modal and unimodal distribution of diffusion ages (kt). Uni-modal domains are typically younger, but there is no systematic variation in scarp age with distance along the CDD. Scarps yielding negative kt ages (i.e. scarps steeper than Θo) are common in the north, near inferred locations of important historic seismic events. Microseismicity drops off significantly adjacent to these very young scarp arrays, which likely reflects a recent post-seismic stress drop. Domains of high seismic risk are identified by high microseismicity and lack of young scarps. Minimum estimates of the diffusivity constant (k) are calculated by coupling scarp diffusion ages and 10Be surface exposure ages of the faulted deposits. In the southernmost SEM a Q6 terrace with a minimum surface exposure age t = 233±6.6 ky (weighted mean of six rock samples) is cut by scarps with an average kt = 11.25±9.31 m2, which

    We study postseismic deformation after the Mw 7.7 earthquake in the Balochistan region of western Pakistan on 24 September 2013 and the Mw 7.2 El Mayor-Cucapah (EMC) earthquake in Baja California of northern Mexico on 4 April 2010. Pakistan InSAR measurements from the German TerraSAR-X (TSX) and Canadian RADARSAT-2 (RS2) satellites include TSX narrow stripmap beams on a descending track, RS2 wide strip modes, and TSX wide-swath ScanSAR images on an ascending track, specially acquired with interferometric alignment of ScanSAR bursts. For the EMC earthquake, InSAR includes Envisat, ALOS, and RS2 satellites and NASA/JPL UAVSAR airborne InSAR, with piece-wise time coverage. Plate Boundary Observatory acquires continuous GPS data and others collect campaign GPS. Interferograms show significant afterslip on both main ruptures in the first weeks and months, not masked by the atmospheric effects. Balochistan shallow afterslip reaches at least 10 cm in 2-4 months in the same area as the largest coseismic slip, but less near the aftershock activity. Rapid afterslip was observed primarily at the ends of the EMC mainshock rupture where the strike changes, with magnitudes up to 30 cm. Large variations of tropospheric water vapor complicate measurement of small long-wavelength deformation so we do time series analysis. We expect viscoelastic relaxation after these two strike-slip earthquakes to differ due to completely opposite tectonic settings: EMC earthquake in the Salton Trough rift and fast-moving strike-slip system, where crust and lithosphere are thin and hot with very shallow asthenosphere, and Balochistan earthquake in the shortening Makran accretional prism with much slower strike-slip deformation rates and cold and thick lithosphere of the subducting Arabian plate directly beneath it, so asthenosphere is much deeper. Studies have found rapid and large viscoelastic relaxation for the EMC quake, but we don't expect measurable relaxation in the Balochistan area in the

    We evaluated spectral amplification factors of long-period ground motions (3 to 10 s) in the Los Angeles (LA) basin by computing Fourier spectral ratios of the basin sites with respect to the surrounding reference hard-rock sites from the Mw7.2 April 4, 2010 El Mayor-Cucapah earthquake records and presented period-specific (4, 6, 8 and 10 s) maps of amplification factors for the long periods. This earthquake was the first event providing many (236) high-quality recordings to study spatial variation of long-period amplification in the LA basin. We also tried numerical wave propagation simulations for two of the recent 3D seismic-velocity models for south California: SCEC (Southern California Earthquake Center) CVM (Community Velocity Model)-4.0 and CVM-H 6.2 to examine how these models account for the observed long-period amplification factors. Comparison of the period-specific maps of amplification factors between the observation and the simulation for the two velocity models shows that both CVM-4.0 and CVM-H 6.2 can roughly reproduce the observed amplification factors with the period range of 8 to 10 s in the LA basin. Concerning the shorter-period range (4 to 6 s), however, both of the two models leave more to be improved so that the observed amplification factors can be better simulated. We also find that CVM-4.0 has an advantage over CVM-H 6.2 in terms of the south-eastern part of the LA basin, because CVM-H 6.2 indicates non-observed large amplification there, while CVM-4.0 does not indicate the false amplification. For the period of 10 s, the largest amplification factor of about 5 was observed in the central part of the LA basin, which is well simulated in terms of good agreements between the observed and the simulated amplification factors. The simulation from the two velocity models also indicates the large amplification even in the San Gabriel (SG) valley, which disagrees with the observation. For 8 s, larger amplification factors of about 5 were observed

    The Pacific-North America plate boundary character changes southward from the strike-slip and transpressional configuration along most of California to oblique rifting in the Gulf of California, with a transitional zone of transtension beneath the Salton Trough in southernmost California and northern Mexico. The Salton Trough is characterized by extremely high heat flow and thin lithosphere with a thick fill of sedimentary material delivered by the Colorado River during the past 5-6 million years. Because of the rapid sedimentation, most of the faults in Salton Trough are buried and reveal themselves when they slip either seismically or aseismically. They can also be located by refraction and reflection of seismic waves. The 4 April 2010 El Mayor-Cucapah earthquake (Mw 7.2) in Baja California and Sonora, Mexico is probably the largest earthquake in the Salton Trough for at least 120 years, and had primarily right-lateral strike-slip motion. The earthquake ruptured a complex set of faults that lie to the west of the main plate boundary fault, the Cerro Prieto Fault, and shows that the strike-slip fault system in the southern Salton Trough has multiple sub-parallel active faults, similar to southern California. The Cerro Prieto Fault is still likely absorbing the majority of strain in the plate boundary. We study the coseismic and postseismic deformation of the 2010 earthquake with interferometric analysis of synthetic aperture radar (SAR) images (InSAR) and pixel tracking by subpixel correlation of SAR and optical images. We combine sampled InSAR and subpixel correlation results with GPS (Global Positioning System) offsets at PBO (Plate Boundary Observatory) stations to estimate the likely subsurface geometry of the major faults that slipped during the earthquake and to derive a static coseismic slip model. We constrained the surface locations of the fault segments to mapped locations in the Sierra Cucapah to the northwest of the epicenter. SAR along-track offsets

    El estudio de la actividad solar con el telescopio para ondas submilimétricas (SST), nos permite, por vez primera, trabajar con una resolución temporal de milisegundos. Este hecho ha permitido observar emisión nunca antes comprobada, pulsos o flashes extremadamente rápidos provenientes de las regiones activas, los cuales parecen preanunciar fulguraciones en dichas regiones. Se muestra, como ejemplo, una fulguración observada con el telescopio HASTA en Hα, y los pulsos rápidos que la preceden observados con el SST. Para cuantificar la influencia de la atmósfera terrestre en los datos registrados, se está estudiando la variabilidad temporal de las opacidades a las frecuecias de trabajo (212 y 405 Ghz), es decir los rangos de tiempo para los cuales la opacidad puede variar apreciablemente. Con este fin se calcula la eficiencia de cada canal multiplicada por la temperatura del Sol a estas frecuencias (estas son conocidas con una incerteza del 20 %). Se muestran los resultados obtenidos para cada canal, en donde se grafica este producto como función de la opacidad.

    Multi--epoch photometry of galaxies is a key tool for the exploration and discovery of astrophysical events in the time domain. There are a number of methods to carry out these studies, with different performances that depend on the instrumental configurations, on wide-field, optical transient search. We apply several time series analysis tools and analyze their performances on transient searches, defining a figure of merit on the basis of false discovery rates. The searches were performed on light curves extracted from injected Kilonova events on top of simulated images of galaxies with different Sérsic profiles and several noise and image degradation sources. We implemented aperture photometry and Difference Image Photometry and evaluated the ability of the methods to retrieve the signal.

    The close approach of comet 1996 B2 (Hyakutake) was observed in very good sky conditions during the night between March 24 and 25. A sequence of photographs taken with a 180 mm f/2,8 telephoto lens shows a knot with a high proper motion in the plasma tail related to a disconnection event. The authors find that the average velocity of the plasma knot was 32.3 km/sec on March 25.0, 53.6 km/sec on March 25.7 and 76.1 km/sec on March 26.5. The average acceleration due to the solar wind was close to 0.0003 km/sec. Extrapolating the data one also finds that the beginning of the disconnection event was around March 24.7.

    In this work we present preliminary results obtained from the analysis carried out on the medium-size bubble structures located in the southeast region of the Large Magellanic Cloud (LMC). We determine the characteristic parameters of these structures (surface brightness; electronic density; emission measure; mass; luminosity; ambient density; age; energy; among others). This will allow us to discriminate which is the origin (stellar wind; supernova explosion; or other mechanisms) of the different bubbles that form the LMC9 supershell. Thus; we will try to determine whether the analyzed objects have kinematically some identity as a group; or they are relatively isolated objects on the diffuse background they belong to.

    2013-04-01

    Chemical analysis of major elements was used to investigate the characteristics of various springs and surface water in the Radovna River valley. The valley is situated in the north-western part of Slovenia. It is 17-kilometre long Alpine river flowing between karstic plateaus of Pokljuka and Mežakla confluenting with Sava Dolinka River. Wider area of the valley is built up by Triassic limestone and dolomite. Quaternary alluvial and glacial sediments occur in the bottom of the valley and on the slopes of the plateaus. Water was sampled monthly from May 2005 till March 2007 at 10 locations along the valley. Locations are divided into: 5 springs, 3 surface water locations, 1 small lake and 1 artesian borehole. On site conductivity, pH and water temperature was measured and samples for chemical analyses were collected. Groundwater, spring water and surface water are related to carbonate rocks; therefore the pH of the samples is in range between 7.1 and 8.4. In most cases pH of river water is higher than that of groundwater and spring water. Conductivity of the water varied in the interval between 188 μS/cm and 374 μS/cm. Results of chemical analyses show that concentration of Ca2+ exceeds that of Mg2+ in all of the samples and Ca/Mg ratio varies between 2.6 and 16.8. The concentration of Na+ is lower than Mg2+, but always higher than that of K+. Predominant anion is the HCO3- and varies between 100 mg/l and 211 mg/l. Concentration of anions Cl-, NO3- and SO42- are low and range from 0.1 mg/l to 7.47 mg/l and between 0.62 mg/l and 12 mg/l for Cl- and SO42-, respectively. NO3- is in almost all of the samples below 1 mg/l. Water data shows that waters are alkaline and the dominant facies is Ca-Mg-HCO3-. Ion concentrations fluctuate seasonally and are related to changes in discharge. In winter and early spring, when the discharge is low, the ion concentrations are higher and in late spring and summer during snowmelt, when the discharge is higher, the ion concentration are lower. Generally, ion concentrations in the water are also increasing downstream from the main spring. Chemical analyses of the water samples reflect typical karst spring dynamics and dynamics of groundwater fluctuations in the alluvium. Along the course of the river, water flow is increasing due to great amount of groundwater drainage in to the stream, therefore the chemical concentrations are increasing downstream.

  17. Prenatal care. Appointment study: a survey by the Infant Mortality Work Group of the Mayor's Advisory Council on Child Health.

    PubMed

    1993-01-01

    This biopsy of the prenatal care system provides plain evidence of weaknesses within the infrastructure and details the inconveniences New York City women who rely on public services must face. The unwillingness of some of the municipal clinics to accept pregnancy test results from their sister hospitals or the Department of Health's free-pregnancy testing program exemplifies one of the bureaucratic barriers in the system, and one which could be rectified easily given sufficient determination. Other bureaucratic barriers, such as the inability to schedule an appointment unless a woman is registered at the clinic, suggest the need for a media campaign urging women of reproductive age to register with a health care provider before becoming pregnant. The solution to the language barrier confronted by Spanish women requires a commitment to hiring bilingual clerical staff. Lastly, the problems of being placed "on-hold" or frequent busy signals and the high number of clinic visits made before seeing a physician can only be ameliorated by an increase in funding for prenatal care clinic staffing, for support staff and professionals alike. The survey, conducted over the course of 2 weeks with available city staff and equipment, is a relatively inexpensive and effective method for evaluating the prenatal care system and should be repeated in order to document systematically the anecdotal reports shared by clinic administration and clinic patients alike.

  18. Interactive Physical Simulation of Catheter Motion within Mayor Vessel Structures and Cavities for ASD/VSD Treatment

    2007-03-01

    Simulation systems are becoming increasingly essential in medical education. Hereby, capturing the physical behaviour of the real world requires a sophisticated modelling of instruments within the virtual environment. Most models currently used are not capable of user interactive simulations due to the computation of the complex underlying analytical equations. Alternatives are often based on simplifying mass-spring systems, being able to deliver high update rates that come at the cost of less realistic motion. In addition, most techniques are limited to narrow and tubular vessel structures or restrict shape alterations to two degrees of freedom, not allowing instrument deformations like torsion. In contrast, our approach combines high update rates with highly realistic motion and can in addition be used with respect to arbitrary structures like vessels or cavities (e.g. atrium, ventricle) without limiting the degrees of freedom. Based on energy minimization, bending energies and vessel structures are considered as linear elastic elements; energies are evaluated at regularly spaced points on the instrument, while the distance of the points is fixed, i.e. we simulate an articulated structure of joints with fixed connections between them. Arbitrary tissue structures are modeled through adaptive distance fields and are connected by nodes via an undirected graph system. The instrument points are linked to nodes by a system of rules. Energy minimization uses a Quasi Newton method without preconditioning and, hereby, gradients are estimated using a combination of analytical and numerical terms. Results show a high quality in motion simulation when compared to a phantom model. The approach is also robust and fast. Simulating an instrument with 100 joints runs at 100 Hz on a 3 GHz PC.

    Palma, T.; Clariá, J. J.; Geisler, D.; Ahumada, A. V.

    We present results obtained for 41 faint star clusters located in the bar and the disc of the Large Magellanic Cloud (LMC). The observations were carried out with the ``Victor Blanco'' 4m telescope at Cerro Tololo Inter-American Observatory using the Washington and Kron-Cousins filters. Clusters' linear radii were determined from the stellar density radial profiles. Using theoretical isochrones; we derived ages and metallicities from extracted color-magnitude diagrams; previously cleaned from field star contamination. Whenever possible; we also derived ages using the parameter and estimated metallicities from the Standard Giant Branch procedure. We find that the two methods for both age and metallicitiy determination are in good agreement with each other. Since none of the observed clusters has been previously studied; the present fundamental parameter determinations turn out to be the first ones. Seventeen clusters were found to be intermediate-age clusters (1-2 Gyr); with [Fe/H] values ranging from -0.4 to -0.8. The remaining 24 clusters are aged between 125 and 900 Myr and their metallicities range between 0.0 and -0.4. FULL TEXT IN SPANISH

CMD cluster features turn out to be identifiable when performing annular extrac- tions around their respective centres, once they were cleaned from field star contamination; their main sequences extending from one up to four mag- nitudes downwards. The clusters resulted to be small angular size objects projected or immersed in dense star fields, as judged from their radial stellar density profiles, so that crowding effect could be responsible for the limited magnitude reached in some cases. We estimated their ages from isochrone fitting - along with the E(B - V ) colour excesses - assuming a metallicity of Z = 0.008 ([Fe/H] = -0.4 dex) and a LMC distance modulus of (m - M)o = 18.50 ± 0.10 mag.

    Introducción La encefalitis por anticuerpos contra el receptor de N-metil-D-aspartato (NMDA) es una entidad cada vez más diagnosticada en edad pediátrica. A diferencia de los adultos, en muchos casos no se asocia a tumores y las manifestaciones iniciales en niños más frecuentes son crisis convulsivas y trastornos del movimiento, mientras que en los adultos predominan las alteraciones psiquiátricas. Casos clínicos Presentamos seis casos pediátricos confirmados con anticuerpos contra la subunidad NR1 del receptor de NMDA en suero y líquido cefalorraquídeo. Cinco de los casos comenzaron con crisis convulsivas como manifestación clínica inicial antes de desarrollar el cuadro clásico de esta entidad. En todos los casos se utilizaron esteroides como primera línea de tratamiento, con los que sólo se observó control de las manifestaciones en uno, por lo que el resto de los pacientes requirió inmunomoduladores de segunda línea. Todos los pacientes recibieron metotrexato como tratamiento inmunomodulador para evitar recaídas y la evolución fue a la mejoría en todos ellos. Conclusiones En nuestra serie de pacientes con encefalitis por anticuerpos contra el receptor de NMDA, ninguno se asoció a tumores. Todos los casos recibieron metotrexato por lo menos durante un año, no observamos eventos adversos clínicos ni por laboratorio, ni hubo secuelas neurológicas ni recaídas durante el tratamiento. Aunque es una serie pequeña y es deseable incrementar el número y tiempo de evolución, consideramos el metotrexato una excelente alternativa como tratamiento inmunomodulador para esta patología.

    Sediments of the Sima de los Huesos vary greatly over distances of a few meters. This is typical of interior cave facies, and caused by cycles of cut and fill. Mud breccias containing human bones, grading upwards to mud containing bear bones, fill an irregular surface cut into basal marls and sands. The lack of bedding and the chaotic abundance of fragile speleothem clasts in the fossiliferous muds suggests that the deposit was originally a subterranean pond facies, and that after emplacement of the human remains, underwent vigorous post-depositional rotation and collapse and brecciation, caused by underlying bedrock dissolution and undermining. The fossiliferous deposits are capped by flowstone and guano-bearing muds which lack large-mammal fossils. U-series and radiocarbon dating indicates the capping flowstones formed from about 68 ka to about 25 ka. U-series analyses of speleothem clasts among the human fossils indicate that all are at, or close to, isotopic equilibrium (>350 ka). The distribution of U-series dates for 25 bear bones (154??66ka) and for 16 human bones (148??34 ka) is similar and rather broad. Because the human bones seem to be stratigraphically older than those of the bears, the results would indicate that most of the bones have been accumulating uranium irregularly with time. Electron spin resonance (ESR) analyses of six selected bear bones indicates dates of 189??28 ka, for which each is concordant with their corresponding U-series date (181??41 ka). Combined ESR and U-series dates for these samples yielded 200??4 ka. Such agreement is highly suggestive that uranium uptake in these bones was close to the early-uptake (EU) model, and the dates are essentially correct. Another three selected samples yielded combined ESR-U-series dates of 320??4 ka with a modeled intermediate-mode of uranium uptake. The dating results, therefore, seem to provide a firm minimum age of about 200 ka for the human entry; and suggestive evidence of entry before 320 ka. ?? 1997 Academic Press Limited.

  4. Effects of the El Mayor Cucapah April 4, 2010 earthquake and water management decisions on the Colorado River Delta tidal inundation patterns: implications for shorebirds habitat availability

    2010-12-01

    The Upper Gulf of California and Colorado River Delta (CRD) provide feeding and resting areas for migratory and resident shorebirds. Coastal and inland wetlands create a variety of habitats that support 31 shorebird species. Total shorebirds during the winter and spring migration ranges from 56,156 to 195,073. The Cienega de Santa Clara is an artificial wetland that receives saline water inflows from the United States, and the southeastern portion (the Santa Clara Slough) receives a mix of brackish effluent from the Cienega and occasional tidal inundation during extreme high tides. This transitional wetland between the sea and the land is one of the main shorebird aggregation areas within the CRD, supporting 29 to 75% of the individuals using the entire Upper Gulf and CRD. The Cienega de Santa Clara is currently experiencing a 30% reduction in inflows due to operation of the Yuma Desalting Plant in the United States. The 2010 Baja California earthquake caused changes in the tidal water inflows patterns in the delta. Time sequence Landsat images and aerial observations showed that a new wetland area has been created since tidal water inflows are now diverted from the southeast edge of the Cienega to the southwest areas due to subsidence effects. The aim of this study was to document the changes in the shorebird inland habitats to predict shifts in shorebird habitat use by using aerial and ground surveys before and after the earthquake. Preliminary results shows that some of the areas with a high density of shorebird use has dried out mainly as a consequence of the reduction in water inflows to the Cienega from the United States and diversion of water from the Santa Clara Slough to the new tidal basins northwest of the Slough. Aerial surveys suggest that shorebirds were not yet visiting the new wetland area during the past spring migration and were more abundant over the San Felipe coastline and Montague Island. Shorebird habitat has been influenced by a combination of water management decisions, tidal dynamics, and landform changes due to the recent seismic event in the CRD. Further monitoring is needed to determine if shorebirds will relocate to new habitat or diminish in numbers in this important ecosystem.

    Sediments of the Sima de los Huesos vary greatly over distances of a few meters. This is typical of interior cave facies, and caused by cycles of cut and fill. Mud breccias containing human bones, grading upwards to mud containing bear bones, fill an irregular surface cut into basal marks and sands. The lack of Bedding and the chaotic abundance of fragile speleothem clasts in the fossiliferous muds suggests that the deposit was originally a subterranean pond facies, and that after emplacement of the human remains, underwent vigorous post-depositional rotation and collapse and brecciation, caused by underlying bedrock dissolution and undermining. The fossiliferous deposits are capped by flowstone and guano-bearing muds which lack large-mammal fossils. U-series and radiocarbon dating indicates the capping flowstones formed from about 68 ka to about 25 ka. U-series analyses of speleothem clasts among the human fossils indicate that all are at, or close to, isotopic equilibrium (> 350 ka). The distribution of U-series dates for 25 bear bones (154 +/- 66 ka) and for 16 human bones (148 +/- 34 ka) is similar and rather broad. Because the human bones seem to be stratigraphically older than chose of the bears, the results would indicate that most of the bones have been accumulating uranium irregularly with time. Electron spin resonance (ESR) analyses of six selected bear bones indicates dates of 189 +/- 28 ka, for which each is cordant with their corresponding U-series date (181 +/- 41 ka). Combined ESR and U-series dates for these samples yielded 200 +/- 4 ka. Such agreement is highly suggestive that uranium uptake in these bones was close to the early-uptake (EU) model, and the dates are essentially correct. Another three selected samples yielded combined ESR U-series dates of 320 +/- 4 ka with a modeled intermediate-mode of uranium uptake. The dating results, therefore, seem to provide a firm minimum age of about 200 ka for the human entry: and suggestive evidence of entry before 320 ka. PMID:9300339

    The fit of synthetic spectra has proved to be a powerful tool for determining astrophysical parameters of stellar clusters (SCs). Such methodology is particularly useful to treat integrated spectra of extragalactic SCs. In this work, we present the results obtained by applying this technique to a sample of SCs belonging to the Large Magellanic Cloud (LMC) observed from CASLEO, and using the starlight code. The fitting of the data was performed by means of evolutive--synthesis models of simple--stellar populations of different ages and metallicities, based on the MILESM stellar libraries. The integrated spectra of 34 SCs of the LMC were fitted in order to obtain the age and metallicity of each object. This study also presents a comparison between the properties derived from those fittings and the method of confrontation of our observations with spectral templates of well known ages.

    Vaginosis bacteriana (VB) es una infección caracterizada por el cambio en la microflora de la vagina, asociándose a resultados adversos del embarazo y a la adquisición de infecciones de transmisión sexual (ITS), incluyendo el VIH. En este estudio se buscó la asociación entre el uso de duchas vaginales y otros factores de riesgos con VB. Se usó un diseño observacional descriptivo transversal prospectivo, en 1,252 mujeres que asistieron al servicio de planificación familiar de tres hospitales nacionales (Dos de Mayo, Arzobispo Loayza, San Bartolomé) y el Instituto Materno Perinatal, durante el año 1997. Se utilizó un cuestionario estructurado donde se registraron variables socio demográficas y características del estilo de vida de las participantes. VB fue diagnosticada mediante el puntaje de Nugent. Se empleó análisis de regresión logística para calcular odds ratio (OR) e intervalos de confianza al 95%. La edad promedio de las participantes fue 25.1 ± 4,7 años, el 23.4% tenían más de 11 años de educación. La prevalencía de VB fue 20,1%. Las mujeres que practicaban duchas vaginales tuvieron 2.28 veces (OR = 2.28, IC 95% [1.0–5.0]) mayor probabilidad de tener VB comparado con aquellas que no lo practicaban. Tener dos o más parejas sexuales estuvo asociado con 2.0 veces (OR =2.0, IC 95% [1.2–3.5]) mayor probabilidad de adquirir VB comparado con aquellas que habían tenido solo una pareja sexual. Las participantes que iniciaron una relación sexual a una edad temprana tuvieron 1.4 veces (OR=1.4, IC 95% [1.0 –1.9]) mayor probabilidad de adquirir VB. El uso de duchas vaginales es un factor de riesgo de VB. Los programas destinados a la salud de la mujer deben abordar las repercusiones perjudiciales para la salud asociados con las duchas vaginales. PMID:21132048

    Introducción: existe una alta prevalencia de sedentarismo, sobrepeso y obesidad en jóvenes universitarios. Objetivo: el propósito del estudio fue determinar los efectos de un programa de entrenamiento intervalado de alta intensidad (HIIT) sobre el perfil antropométrico, glicemia basal y VO 2 máx (consumo máximo de oxígeno) de jóvenes sedentarios con malnutrición por exceso. Material y métodos: 6 mujeres y 2 hombres (2 obesos y 6 con sobrepeso) se sometieron a un programa de entrenamiento de alta intensidad de 8 semanas de duración (3 sesiones/semana). Se evaluó en ayuno y posterior a 72 horas de la última intervención; peso, índice de masa corporal (IMC), contorno de cintura (CC), perímetro de cadera y glicemia de basal. El VO 2 máx fue evaluado en condiciones normales previo a la primera sesión. Resultados: las variables de estudio no presentaron cambios significativos (p > 0,05), pero reportaron disminuciones porcentuales. El peso disminuyó un 0,18%, el IMC un 0,27%, el CC 2,67%, el perímetro de cadera un 1,15%, y el VO 2 máx un 0,48%. La glicemia basal presentó la mayor disminución, pasó de 95,13 ± 23,91 a 89,88 ± 12,45 mg/dl (5,52%), estabilizando y mejorando sus niveles en cada uno de los participantes. Conclusiones: el programa de entrenamiento intervalado de alta intensidad fue factible de realizar sin resultados adversos para la salud de los participantes, la glicemia basal mostró la mayor variación, estabilizando sus valores en los participantes, lo que es un indicador positivo dentro del programa. Es necesario seguir investigando sobre esta metodología HIIT y aumentar los tiempos de estudio para ver los cambios que se pueden producir en distintos parámetros metabólicos, antropométricos y físicos en población con malnutrición por exceso.

    This descriptive comparative study examined differences in personal characteristics, exercise self-efficacy, benefits and barriers of independent elderly women to perform physical activity (PA) according with the PA level. Two hundred three women older than 60 years of age, from a community located in Nuevo Leon, Mexico participated in the study. Data was collected using: a) A personal data questionnaire, b) Exercise Self-Efficacy Scale, c) Exercise Benefits/ Barriers Scale and d) Physical Activity Scale for the Elderly were completed. Age was similar in participants with low and acceptable PA level. Participants with lower levels of PA reported consuming more medications, fewer years of education and lower values of exercise self-efficacy, benefits and barriers. In this sample, exercise self-efficacy and benefits were positively associated with the PA level. PMID:27257188

    Complementing our recent Washington photometric studies on intermediate age and young Large Magellanic Cloud (LMC) clusters, we present in this work new results for 6 previously unstudied star clusters in the transition range 200-700 Myr. We study NGC 1836, NGC 1860 and NGC 1865, which are projected on the LMC bar; SL 444, also located in the central disc but outside the bar, and LW 224 and SL 548, both located in the outer disc. We derive ages and metallicities from extracted T1 versus C-T1 colour-magnitude diagrams (CMDs), using theoretical isochrones recently computed for the Washington system. For the metallicity determinations, these CMDs are particularly sensitive. We also estimate ages and metallicities of the surrounding fields of NGC 1860 and NGC 1865 by employing the δT1 index and theoretical isochrones.

    Resumen El rastreo de cáncer colorrectal (CCR) cuenta con fuertes evidencias en su favor. Datos preliminares indican que a pesar de ello no se lleva a cabo con la frecuencia adecuada. Se intenta aquí determinar, dentro de un Sistema de Salud que cuenta con los recursos necesarios, los elementos que facilitan o generan barreras para concretar esta práctica preventiva, cuántos individuos lo ponen en práctica y qué predice esta conducta. Se realizó una encuesta telefónica a los afiliados de una Obra Social de empleados de la Universidad de Buenos Aires, de los que 132 completaron el cuestionario (tasa de respuesta 70%). Los elementos considerados facilitadores del rastreo obtuvieron respuestas afirmativas en el 64 a 97%, mientras que los que definían barreras un 11 a 27%. En este último grupo, una categoría diferenciada la constituía el miedo a los efectos adversos: 39%, y el sentimiento de vergüenza relacionado con los procedimientos: 30%. Un 33% de los encuestados tenían hecho un método de rastreo, mayoritariamente de sangre oculta (27), sigmoideoscopía (11) y colonoscopía (20). Una mayoría afirmó que “se haría el procedimiento si el médico se lo recomendara” (95%), o “no se lo haría excepto que su médico se lo aconseje” (87%). Contestar afirmativamente que “los médicos hacen lo mejor para los pacientes” se asoció con haberse hecho un método de rastreo de CCR, OR 1.55 (IC 95%: 1.02-2.37) p: 0.04. El grupo de individuos estudiado parece bien predispuesto para el rastreo del CCR, la recomendación médica sería aquí un determinante prominente para ponerlo en práctica. PMID:19414294

    El embarazo representa un desafío desde el punto de vista nutricional, debido a que las necesidades de nutrientes están aumentadas y una alteración en su ingesta puede afectar la salud materno-fetal. Estados deficitarios en micronutrientes están relacionados con preeclampsia, retraso del crecimiento intrauterino, aborto y anomalías congénitas. Actualmente, la dieta de muchas madres gestantes es insuficiente en micronutrientes, siendo necesaria su suplementación. Se recomienda la suplementación con ácido fólico en dosis de 400 μg/día, y de 5 mg en embarazadas de riesgo, debiendo comenzar al menos 1 mes antes de la concepción y durante las primeras 12 semanas de gestación, y prolongarla durante todo el embarazo en madres con riesgo nutricional. Es importante vigilar la dosis adecuada de ácido fólico para prevenir los posibles efectos adversos derivados de su acumulación plasmática no metabolizada. Un elevado porcentaje de gestantes presenta anemia ferropénica, estando recomendado el uso intermitente de suplementos con hierro (menor alteración gastrointestinal y estrés oxidativo); no recomendándose en madres no anémicas (con hemoglobina > 13,5 g/L). Dado que la absorción de calcio está aumentada hasta un 40% en gestación, no se recomienda su suplementación en madres con ingestas adecuadas (3 lácteos/día), debiéndose reservar su uso a madres con ingestas insuficientes y/o que tengan alto riesgo de preeclampsia. Respecto al iodo, existen posicionamientos contradictorios por parte de distintos grupos de trabajo, estableciéndose la suplementación con yoduro potásico en mujeres que no alcanzan las ingestas recomendadas con su dieta (3 raciones de leche y derivados lácteos + 2 g de sal yodada). Dado que la vitamina A y D pueden ser tóxicas para la madre y el feto, no está recomendada su suplementación excepto en casos de deficiencia. Aunque la administración de suplementos con varios micronutrientes puede repercutir favorablemente en el

    Se reportan observaciones fotográficas del cometa Halley, obtenidas con los telescopios Schmidt de 1-m del CIDA, y de 35 cms de la ULA. Se hicieron exposiciones desde 2 segundos a 30 minutos y se utilizaron emulsiones IIa-O, 103a-F, y 103a-D, guladas manualmente 0 automaticámente. Las imágenes fueron digitalizadas con el microdensitómetro PDS, y procesadas con el sistema HACIENDA del CCIBM. Se experimentó con la Transformada de Fourier en dos dimensiones, y con la aplicación de filtros de paso alto y bajo. Se encontró que el metodo de "autocorrelación" es el mejor para separar "la vegetación" de "la montaña". Se aplicaron diversas técnicas a fin de cubrir ambos extremos: a) enfatizar detalles débiles en la cola, y b) penetrar en las regiones más intensas de la coma. Se lograron ambos objetivos. Detalles en la cola permitieron determinar velocidades de propagación de unos 50 a 90 kms/ seg. Se pudieron detectar no menos de tres perturbaciones en "Y", y una en 5? Co de Cisne). Se cree que las primeras están asociadas a eventos de desconexión. Se puede separar la cola de gas de la de polvo. Las fotos de color permiten enfatizar diferentes regiones espectrales con mayor claridad aún. El "balance" del color puede ser hecho con la computadora.

    Uno de los aspectos importantes relativos a la geodinámica del interior terrestre es la correlación entre los eventos de cambio en la velocidad de rotación terrestre y los determinados en los elementos del campo geomagnético por ejemplo, la Declinación Magnética, o los coeficientes de los modelos matemáticos de representación global de dicho campo. En este trabajo se presentan los resultados de las características espectrales de los cambios observados en la longitud del día (ldd), y su relación con la estructura espectral de las coeficientes de los modelos matemáticos de campo denominados Campo Internacional Geomagnético de Referencia (CIGR). El intervalo estudiado comprende los últimos 100 años. Los resultados muestran una correlación en las bandas de 60 y 30 años, con posibles períodos mucho mayores que no son posibles determinar a partir de los modelos de CIRG. Se efectúa una simulación a partir de los resultados obtenidos por la aplicación del método de máxima entropía con longitudes del filtro predictor de error comprendida entre el 10% y el 95% de la longitud de la serie analizada. Se observan procesos sicrónicos y asincrónicos que, en muy largos intervalos de tiempos, podrían suponerse como caóticos.

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

     RESUMEN              Fundamento. Identificar factores asociados a la demora prehospitalaria en personas que han tenido un síndrome coronario agudo             Método. Se estudiaron mediante encuesta pacientes ingresados por síndrome coronario agudo en los 33 hospitales públicos andaluces, obteniéndose información sobre diferentes tipos de variables: socio-demográficas, contextuales, clínicas, percepción, actuaciones, y transporte. Se aplicaron modelos de regresión logística multivariante para calcular las odds ratio para la demora.             Resultados. De los 1.416 pacientes en total, más de la mitad tuvieron una demora superior a la hora. Se asocia a la distancia al hospital y al medio de transporte: cuando el evento ocurre en la misma ciudad del hospital, utilizar medios propios aumenta la demora, odds ratio= 1,51 (1,02-2,23);  si la distancia es entre 1-25 kilómetros, no hay una diferencia entre medios propios y ambulancia, odds ratio = 1,41 y odds ratio = 1,43 respectivamente; y cuando supera los25 kilómetros la ambulancia implica mayor demora, odds ratio = 3,13 y odds ratio = 2,20 respectivamente. Además, la sintomatología típica reduce la demora entre los hombres, pero la aumenta entre las mujeres. Asimismo, no darle importancia, esperar a la resolución de los síntomas, buscar atención sanitaria diferente a urgencias hospitalarias o al 061, tener antecedentes, encontrarse fuera de la vivienda habitual, y tener ingresos menores de 1.500 euros aumentan la demora. Tener síntomas respiratorios la reduce.             Conclusiones. La demora prehospitalaria no se ajusta a las recomendaciones sanitarias, asociándose al  entorno físico y social, a factores clínicos, y de percepción y actitudinales de los sujetos.              Palabras clave. Síndrome coronario agudo. Demora prehospitalaria. Género. Servicios de emergencias sanitarias. Desigualdades. PMID:27125609

    2002-09-01

    dans l'aquifère captif profond, puisque la recharge à partir des aquifères superficiels au travers de la couche de limon est la seule alimentation de l'aquifère profond. Une analyse des distributions spatiales de l'abaissement du niveau piézométrique et des tassements du sol montre que la région soumise à l'abaissement maximal de piézométrie n'est pas nécessairement celle des tassements maximaux du sol liés à la présence de la couche de limon non consolidé. Une simple révision des débits de pompage basée sur la distribution spatiale de la couche de limon épaisse peut réduire significativement les tassements du sol. Resumen. La ciudad de Suzhou, situada en el tramo inferior del Río Yangtze, al sudeste de la provincia de Jiangsu, es una de las pocas ciudades chinas que padece problemas serios de subsidencia. Esto ha motivado la realización de un proyecto de investigación en la zona. Estudios geológicos e hidrogeológicos apuntan a un modelo de acuífero multicapa, con tres niveles distintos de lodos blandos de orígenes marino y lacustre. Examinando los registros históricos de extracciones de agua subterránea, así como de nivel piezométrico y de subsidencia, se observa que ésta se halla asociada al bombeo cada vez mayor del acuífero confinado profundo. La hipótesis es que las capas de lodos blandos se van consolidando, si bien la que más contribuye a ello es la tercera, potente y próxima al acuífero más explotado. Se ha realizado un modelo numérico tridimensional en diferencias finitas que representa el sistema acuífero multicapa, con lo que se puede estudiar el efecto de la extracción de agua subterránea en la subsidencia. Calibrando el modelo con niveles piezométricos medidos y con datos de subsidencia, se ha podido estimar los parámetros del acuífero. Los resultados del modelo ajustan de forma razonable con los datos medidos, por lo que el modelo numérico es capaz de reproducir los procesos dinámicos de flujo de aguas

  10. En la búsqueda de características en eyecciones coronales de masa que discriminen entre dos paradigmas físicos en modelos de ECMs

    NASA Astrophysics Data System (ADS)

    Paissan, G.; Stenborg, G.; Rovira, M.

    Se conocen tres diferentes fenómenos de gran escala que ocurren en la atmósfera solar, denominados eyecciones coronales de masa (ECMs), protuberancias eruptivas y grandes fulguraciones de dos bandas. Estos fenómenos están estrechamente relacionados y podrían ser distintas manifestaciones de un único proceso físico. Las ECMs son definidas como eyecciones de gran escala de masa y flujo magnético desde la baja corona al espacio interplanetario. Desde su descubrimiento en los '70, muchos modelos han sido propuestos para explicar su origen y evolución. La explicación física de las ECMs es un tema de debate intenso. No obstante, los modelos pueden sintetizarse en dos grandes grupos: 1) los modelos de inyección de flujo y 2) los modelos de almacenamiento y liberación. En este trabajo, se presentan los estudios realizados con una serie de eventos observados con el coronógrafo MICA (Mirror Coronograph for Argentina), el telescopio en H-alfa HASTA (H-alpha Solar Telescope for Argentina) y los coronógrafos C2 y C3 de la sonda SOHO (Solar and Heliospheric Observatory). Los eventos que pudieron ser identificados como ECMs son contrastados dentro del esquema de los dos paradigmas teóricos propuestos.

  11. Propriedades de estruturas temporais rápidas submilimétricas durante uma grande explosão solar

    NASA Astrophysics Data System (ADS)

    Raulin, J.-P.; Kaufmann, P.; Gimenez de Castro, C. G.; Pacini, A. A.; Makhmutov, V.; Levato, H.; Rovira, M.

    2003-08-01

    Apresentamos novas propriedades de variações rápidas da emissão submilimétrica durante uma das maiores explosões solares do ciclo solar 23. Os dados analisados neste estudo foram obtidos com o Telescópio Solar Submilimétrico (SST), que observa o Sol em 212 GHz e 405 GHz, e comparados com emissões em Raios-X duros e Raios-gama (fótons de energia > 10 MeV), que foram obtidas pelo experimento GRS do Yohkoh. Aplicamos diferentes metodologias para detectar e caracterizar, ao longo do evento, os pulsos submilimétricos (duração de 50-300 ms) detectados acima de uma componente mais lenta (alguns minutos). Os resultados mostram que durante a fase impulsiva, num instante próximo ao tempo do máximo do evento, houve um aumento da ocorrência de maiores e de mais rápidas estruturas temporais. Também identificamos uma boa correlação com as emissões em raios-X e raios-gama (até a faixa de energia 10-100 MeV), indicando que os pulsos rápidos submilimétricos refletiram injeções primárias de energia durante o evento.O espectro do fluxo desses pulsos é crescente com a freqüência entre 212 and 405 GHz, na maioria dos casos, ao contrário do observado para a componente gradual. As posições calculadas para as estruturas rápidas são discretas, compactas e localizadas em toda a área da região ativa, o que é previsto nos modelos de explosões solares decorrentes de instabilidades múltiplas em diferentes pequenas regiões. Por outro lado, a posição calculada para a componente lenta é estável durante a fase impulsiva. Assim, a comparação entre as características do espectro de fluxo e da localização da emissão, para os pulsos rápidos e para a componente gradual, sugere que as respectivas emissões são de natureza diferente.

  12. Pestiviruses.

    PubMed

    Schweizer, Matthias; Peterhans, Ernst

    2014-02-01

    Pestiviruses cause economically important diseases among domestic ruminants and pigs, but they may also infect a wide spectrum of wild species of even-toed ungulates (Artiodactyla). Bovine viral diarrhea virus (BVDV) and Border disease virus of sheep infect their hosts either transiently or persistently. Cellular and humoral immunotolerance to the infecting strain is a unique feature of persistent infection (PI) by ruminant pestiviruses. Persistence, caused by transplacental infection early in fetal development, depends on virally encoded interferon antagonists that inactivate the host's innate immune response to the virus without globally interfering with its function against other viruses. At epidemiological equilibrium, approximately 1-2% of animals are PI. Successful BVDV control programs show that removal of PI animals results in viral extinction in the host population. The nucleotide sequences of ruminant pestiviruses change little during persistent infection. Nevertheless, they display large heterogeneity, pointing to a long history of virus-host coevolution in which avirulent strains are more successful. PMID:25384138

  14. Attenuated sensing of SHH by Ptch1 underlies evolution of bovine limbs.

    2014-07-01

    The large spectrum of limb morphologies reflects the wide evolutionary diversification of the basic pentadactyl pattern in tetrapods. In even-toed ungulates (artiodactyls, including cattle), limbs are adapted for running as a consequence of progressive reduction of their distal skeleton to symmetrical and elongated middle digits with hoofed phalanges. Here we analyse bovine embryos to establish that polarized gene expression is progressively lost during limb development in comparison to the mouse. Notably, the transcriptional upregulation of the Ptch1 gene, which encodes a Sonic hedgehog (SHH) receptor, is disrupted specifically in the bovine limb bud mesenchyme. This is due to evolutionary alteration of a Ptch1 cis-regulatory module, which no longer responds to graded SHH signalling during bovine handplate development.

    ísico na doença arterial coronária, mas a predição de mortalidade e de eventos cardíacos maiores, em pacientes com teste ergométrico positivo para isquemia miocárdica, é limitada. Objetivo: Avaliar a predição de mortalidade e de eventos cardíacos maiores pela ecocardiografia com estresse físico em pacientes com teste ergométrico positivo para isquemia miocárdica. Métodos: Trata-se de uma coorte retrospectiva em que foram estudados 866 pacientes consecutivos, com teste ergométrico positivo para isquemia miocárdica, submetidos à ecocardiografia com estresse físico. Os pacientes foram divididos em dois grupos: ecocardiografia com estresse físico negativa (G1) ou positiva (G2) para isquemia miocárdica. Os desfechos avaliados foram mortalidade por qualquer causa e eventos cardíacos maiores, definidos como óbito cardíaco e infarto agudo do miocárdio não fatal. Resultados: O G2 constituiu-se de 205 (23,7%) pacientes. Durante o seguimento médio de 85,6 ± 15,0 meses, ocorreram 26 óbitos, sendo seis por causa cardíaca, e 25 casos de infarto agudo do miocárdio não fatais. Os preditores independentes de mortalidade foram idade, diabetes melito e a ecocardiografia com estresse físico + (hazard ratio: 2,69; intervalo de confiança de 95%: 1,20 - 6,01; p = 0,016), com os seguintes eventos cardíacos maiores: idade, doença arterial coronária prévia, ecocardiografia com estresse físico + (hazard ratio: 2,75; intervalo de confiança de 95%: 1,15 - 6,53; p = 0,022) e ausência do incremento de 10% na fração de ejeção. A mortalidade por qualquer causa e os eventos cardíacos maiores foram significativamente superiores no G2 (p < 0, 001 e p = 0,001, respectivamente). Conclusão: A ecocardiografia com estresse físico oferece informações prognósticas adicionais em pacientes com teste ergométrico positivo para isquemia miocárdica. PMID:25352460

    In spite of abundant archeological material available in Mexico, archeomagnetic studies are extremely scarce. In this work, we conducted systematic archeointensity measurements on some well-known archeological sites in central and eastern Mexico (e.g., Teotihuacan, Templo Mayor among others) to contribute to the relative and absolute chronology of Mesoamerica. Our sampling strategy was guided largely by Linda Manzanilla's detailed study of two of the most important archeological sites in Central Mexico, Teotihuacan, and Templo Mayor, since we sampled only materials that are already studied and provide more or less coherent archeological ages. Moreover, we incorporated data from some Mexican lava flows that erupted during historic times in order to extend the archeointensity master curve for Mexico and Mesoamerica to the present.

    2010-01-01

    The son of a Lithuanian artist, Antanas Mockus was the president of the National University in Colombia before he became mayor of Bogotá in 1995. As mayor, he transformed the city into a huge classroom, not only bringing to his administration a new view of governing but also transforming the way people exercised their citizenship. Mockus resorted to a creative communicative and pedagogical effort to change the citizens' hearts and minds in favor of peaceful coexistence and legal compliance. Symbols, metaphors, and humor became the language through which the administration would enforce its measures to deal with urban violence. Unconventional techniques, such as a symbolic vaccine against domestic violence and the use of mimes to control traffic circulation and create a sense of shame among those who committed infractions, helped to stop crime and develop a new sense of citizenship.

    Los modelos de Heggie y Ramamani de satélites galácticos en órbitas circulares se basan en una teoría aproximada, por lo que es importante verificar su estabilidad mediante simulaciones numéricas. En esta forma, hemos logrado mostrar que son estables sobre intervalos de tiempo mucho mayores que los que lograron los propios autores de los modelos. Por otra parte, dado que hemos mostrado que el caos es significativo en estos modelos, son un sistema ideal para investigar si, pese a ello, se mantienen estacionarios. Nuestras simulaciones numéricas muestran que, pese al caos, la estacionariedad se mantiene sobre intervalos de centenares de tiempos de cruce del sistema, mucho mayores que los tiempos de Liapunov característicos de sus movimientos caóticos.

    The dates of birth and death of WANG Tao, a famous doctor in Tang dynasty, are not found in literature and scholars have different points upon this subject. It could be sure that WANG Tao was appointed mayor of Huayuan county in the ninth year of Kaiyuan period (721) and in December of the fourteenth year of Tianbao period (756) he the revolt in Hejian. The recording after 756 could not be found in literature. According to the official system in Tang dynasty that officers retired at their age of 70, it could be sure that WANG Tao was less than 70 year old in 756. Considering his age when he was the county mayor in 721, it could be speculated that WANG Tao was born during the third year of Chuigong period (687) to the second year of Changshou period (693), and his death date should be some date after 756. But it couldn't be validated. PMID:21624275

Los diagramas color-magnitud nos permiten identificar numerosas fuentes con exceso infrarrojo, la mayoría de ellas imposible de detectarse en el rango óptico debido a la fuerte absorción del polvo presente en la región. Es altamente probable que la mayoría de estas fuentes con exceso sean protoestrellas, aunque es necesario realizar espectroscopía infrarroja de las mismas para confirmar su naturaleza.

    2014-06-01

    How ought public officials address policy choices that entail trade-offs between desirable public health goods? Increasing cycling improves public health both by promoting physical activity and by decreasing vehicle use, thus reducing vehicular emissions. Proponents of bicycle helmets argue that, used properly, they protect individual cyclists; however, there is concern that mandating helmet use may result in a decrease in cycling. In 2012, New York City Mayor Michael Bloomberg opposed a bicycle helmet mandate, concerned that it would have a negative impact on the city's cycling rate, which he had sought to increase. The mayor did not explain his rationale, leaving constituents unsure why he opposed the proposal. This case study underscores the challenge of creating public policy in the context of competing public health goods. PMID:24825196

    Introducción: Guatemala ha estado experimentando una transición en sus estilos de vida. Mientras que la desnutrición crónica sigue siendo prevalente, se ha experimentado un aumento sustancial de los casos de obesidad. Objetivo: proporcionar información actualizada sobre las nuevas tendencias en cuanto al estado nutricional en Guatemala. Métodos: se diseñó un estudio transversal con una muestra de 392 niños y adolescentes (5-18 años) seleccionados de manera aleatoria. El muestreo fue estratificado según su ubicación geográfica (rural y urbana), sexo y edad. Resultados: alrededor del 62% de la muestra urbana presentó problemas de sobrepeso y un 13,8 de obesidad. Entre los participantes urbanos, la prevalencia de sobrepeso/obesidad fue mayor en el grupo de 11-14 años. El grupo urbano presentó una mayor prevalencia de sobrepeso/obesidad que el grupo rural para todos los grupos de edad (excepto en el grupo de 15-18 años que presentó unos índices de obesidad ligeramente más elevados en el grupo rural). Se observó una mayor prevalencia de retraso en el crecimiento en el grupo rural, excepto para el grupo de edad de 15-18 años. La prevalencia de bajo peso fue significativamente mayor en el grupo rural (25% vs. 1,2%) así como la prevalencia del delgadez, excepto para el grupo de edad de 5-10 años. Conclusión: la alta prevalencia de bajo peso y la de sobrepeso/obesidad coexisten en los niños y adolescentes en Guatemala.

  15. UAVSAR Indication of Right-Lateral Faults in Southern California

    2011-12-01

    UAVSAR data have been collected in southern California since spring of 2009. Data started being routinely collected in fall of 2009. Repeat pass interferometry (RPI) products show multiple lineations that strike SE parallel to the main strike of the San Andreas fault (outside of the Big bend). Aside from slip associated with the 2010 M 7.2 El Mayor Cucapah earthquake the lineations, while prominent in the data products, do not indicate large or any offsets on the faults. Faults that are indicated in the data include the Rialto-Colton fault, and the Superstition Hills fault. The RPI products indicate line of site changes between the ground and the instrument, which in this case is on an airborne platform. The flight lines were designed to be generally perpendicular to strike slip motions in southern California, and as a result should show the maximum component of motion toward the instrument. However, it is not possible to decompose horizontal versus vertical motions. Cross sections across these lineations show no offset, except near the 2010 El Mayor-Cucapah rupture, but show substantial differences in range change near the fault as compared to further from the fault. It is likely that different material properties within the fault zone, coupled with either ground-water migration or shaking from the El Mayor-Cucapah earthquake are the cause of these range change differences. We also discuss conjugate faulting associated with the 2010 earthquake and other crustal deformation observed in the Salton Trough.

    The article highlights the career of Professor Mansour Ali Haseeb (1910 – 1973; DKSM, Dip Bact, FRCPath, FRCP [Lond]), a pioneer worker in health, medical services, biomedical research and medical education in the Sudan. After his graduation from the Kitchener School of Medicine (renamed, Faculty of Medicine, University of Khartoum [U of K]) in 1934, he devoted his life for the development of laboratory medicine. He became the first Sudanese Director of Stack Medical Research Laboratories (1952 – 1962). He made valuable contributions by his services in the vaccine production and implementation programs, most notably in combating small pox, rabies and epidemic meningitis. In 1963 he became the first Sudanese Professor of Microbiology and Parasitology and served as the first Sudanese Dean of the Faculty of Medicine, U of K (1963–1969). He was an active loyal citizen in public life and served in various fields outside the medical profession. As Mayor of Omdurman, he was invited to visit Berlin in 1963 by Willy Brandt, Mayor of West Berlin (1957–1966) and Chancellor of the Federal Republic of Germany (1969 to 1974). Also as Mayor of Omdurman, he represented the City in welcoming Queen Elizabeth II during her visit to Sudan in February 1965. He also received State Medals from Egypt and Ethiopia. In 1973 he was appointed Chairman of the Sudan Medical Research Council, and was awarded the international Dr. Shousha Foundation Prize and Medal by the WHO for his contribution in the advancement of health, research and medical services.

    2010-12-01

    The 2010 El-Mayor Cucapah earthquake was the first earthquake to be observed with UAVSAR. UAVSAR observations, GPS time series analysis, and simulations suggest that the fault that ruptured in the earthquake is coupled to the Elsinore, San Jacinto, and San Andreas faults to the north. GPS and UAVSAR observations indicate a zone of shear that extends southward from the Big Bend of the San Andreas fault near Gorman through the San Fernando Valley towards the Newport-Inglewood fault. The zone steps over to the region of the Elsinore or San Jacinto faults, though the partitioning of strain between the two faults is not as clear. State changes in GPS time series data fall in line with the shear zone through the San Fernando Valley and extend northward from the El Mayor-Cucapah earthquake rupture. Seismicity hotspots also indicate elevated earthquake hazard near the San Fernando Valley and in the Inland Empire near the Elsinore and San Jacinto faults. Inversions of GPS velocity vectors favor a fault underlying the shear zone extending from the Big Bend to the Newport-Inglewood fault over substantial slip on the San Andreas fault under north of Los Angeles. Virtual California simulations of southern California are being analyzed for fault activity associated with the identified shear zone and for subsequent earthquakes that may be related to El Mayor-Cucapah type earthquakes in Baja.

The inter-related, pioneer researchers were led by the Agassizs, Louis and his son Alexander, who explored and described reefs in Florida and the Bahamas. Among their followers were Alfred G. Mayor the founder-director and premier researcher of the Carnegie Laboratory in the Dry Tortugas; C.F. Hartt who first described southernmost reefs off Brazil; Louis Pourtales whose dredging off the Florida coast stimulated interest in organic limestones; and T. Wayland Vaughan whose research ranged from coral biology to the regional geology and history of reefs. The initial 19th century research was sparked by a combination of practical and scientific questions and the what and where of exploration. To build lighthouses on the wreck-strewn Florida reefs one needs to know their foundations. Is the present-day Florida platform a result of reef growth during subsidence a la Darwin or are the reefs merely icing on a limestone cake. In the second phase of research extending from the early 1900's to 1940's, the singular aspects are two dynamic researchers, Alfred Mayor and T. Wayland Vaughan and the Carnegie Institution's Marine Biology Laboratory in the Dry Tortugas. Mayor through his own biological research and his stimulations of other scientists made the Carnegie Laboratory the world center for reef research. Vaughan pioneered connections between reef-building corals, reef deposits and their logical record.

    Em 06 de junho de 2000 (~15: 00-17: 00 UT), o Brazilian Solar Spectroscope (BSS) registrou uma explosão solar intensa no intervalo de freqüência de (1000-2000) MHz, com alta resolução temporal (100 ms) e espectral (5 MHz). A atividade solar relacionada a esta explosão associada à região ativa (AR) 9026 e classificada como X2.3 foi grande. O Ondrejov Observatory registrou rádio emissões até 4,5 GHz. O satélite SOHO registrou uma série de erupções solares, incluindo uma Ejeção de Massa Coronal (CME) tipo "full-halo" (~15: 54 UT). Explosões tipo II/IV também foram registradas. Na faixa de ondas decimétricas, este evento apresentou dois picos distintos (~15: 21 UT e ~16: 42 UT). O primeiro pico coincide com a explosão registrada em raios-X moles (GOES) e em raios-X duros (Yohkoh). Os espectros dinâmicos com alta resolução do BSS revelaram várias estruturas finas, principalmente emissões tipo "zebra" e "fibra", rádio pulsações, emissões tipo III e do único caso de emissões "zebra" harmônicas observado na faixa decimétrica. Neste trabalho, analisamos a evolução temporal e o comportamento global do evento de 06 de junho de 2000, com ênfase na identificação e associação da ocorrência de cada tipo de estrutura fina registrada em rádio com cada etapa da explosão. Resultados preliminares mostraram que, na fase pré-flare, as estruturas finas apresentaram taxa de deriva negativa (~ 70-190 MHz/s). As emissões tipo "zebra" concentram-se na fase de descida do primeiro pico impulsivo e na de subida do segundo pico. Enquanto que as emissões tipo "fibra" ocorrem em ambas fases, mas preferivelmente durante a fase de descida. Os resultados serão apresentados e discutidos.

    A explosão ocorrida no dia 25/08/2001 foi uma das mais intensas do presente ciclo solar em ondas de rádio de altas frequências. Foram medidas em ondas milimétricas e submilimétricas, aproximadamente, 105 e vários milhares de unidades de fluxo solar, respectivamente. Apresentamos um estudo deste evento em múltiplas frequências, desde microondas (1GHz), até ondas submilimétricas (405 GHz) detectadas pelo Telescópio Solar para ondas Submilimétricas (SST). Esta base de dados foi complementada utilizando-se o experimento Yohkoh, incluindo a emissão em raios-X duros e raios-g (até 100 MeV), e imagens em raios-X moles da região ativa envolvida. Enfocamos e discutimos principalmente os seguintes aspectos da fase impulsiva do evento: (i) as implicações deduzidas do espectro eletromagnético, obtido pela primeira vez até 405 GHz; (ii) a dinâmica da região ativa. Os resultados mostram que para explicar o espectro rádio observado, são necessários entre 3.5×1037 e 1.5×1039 elétrons acelerados acima de 20 keV em uma região de campo magnético entre 300 e 800 Gauss. A estimativa do fluxo de fótons que seria produzido por estes elétrons, mostra que grande parte deles não precipitou na baixa atmosfera. A evolução temporal da emissão em raios-X moles revela que a configuração magnética da região ativa foi muito dinâmica durante a fase impulsiva da explosão. Em particular, mostramos que a produção dos elétrons altamente energéticos foi iniciada junto com a aparição, na baixa coroa solar, de um novo sistema compacto de estruturas magnéticas. Este fato sugere que os locais de aceleração estão localizados na baixa atmosfera do Sol, como resultado da interação entre o novo sistema compacto e o campo magnético ambiente da região ativa.

    Com base em (Brandt et al, 1992), centenas de imagens do cometa P/Halley foram visualmente analisadas, objetivando examinar possíveis perturbações magnetohidrodinâmicas ao longo da cauda do tipo I. Do total de 1439 imagens, abrangendo o período entre 16 de outubro de 1982 e 12 de fevereiro de 1991, foram escolhidas 531 do período entre 17 de setembro de 1985 e 06 de julho de 1986 por mostrarem cauda bem desenvolvida e rica de estruturas morfológicas. Nelas constatou-se a existência de 124 estruturas ondulatórias (trens de onda) ao longo da cauda principal, 27 ao longo de caudas secundárias, 109 ondas solitárias (sólitons) ao longo da cauda principal, 36 ao longo de caudas secundárias, 12 caudas do tipo Swan, 47 eventos de desconexão e 23 regiões de adensamento ("knots"). Foi examinada a correlação temporal entre esses diferentes tipos de eventos. Os de desconexão foram analisados isoladamente. Seus movimentos próprios foram calculados, bem como os seus instantes iniciais, o que nos permitiu inferir a passagem do cometa pela fronteira entre setores magnéticos distintos. A velocidade do plasma cometário desconectado foi corrigida dos efeitos de projeção e correlacionada com a distância heliocêntrica do cometa. Também foi investigada a periodicidade de ocorrência das desconexães, e constatado que sua distribuição é bimodal. Por fim, a possibilidade dos modos de propagação de ondas MHD "sausage" e "kink" superficiais ou volumétricas, é discutida no contexto das descontinuidades magnéticas tangenciais. - Brandt, J.C., Niedner Jr., M.B., Rahe, J.: The International Halley Watch Atlas of Large-Scale Phenomena.

    Introducción: la esperanza de vida está aumentando y convirtiéndose en un fenómeno característico de los países desarrollados y, cada vez más, de los países en desarrollo, como Brasil. El proceso de envejecimiento produce cambios en algunas funciones fisiológicas, como la pérdida del olfato o gusto o pérdida de apetito, entre otros, que terminan alterando la ingesta de alimentos de estos individuos.Objetivos: este estudio tuvo como objetivo evaluar el consumo de alimentos de los ancianos y de los ancianos más longevos en una ciudad del sur de Brasil.Métodos: un estudio transversal realizado mediante visitas a domicilio en Palmeira das Missões - RS, Brasil. Los datos sociodemográficos, antropométricos y dietéticos fueron recogidos a través de cuestionarios y recordatorio de 24 horas. La adecuación de nutrientes se evaluó de acuerdo con las ingestas de referencia en la dieta. Los datos fueron analizados utilizando el software SPSS 18.0.Resultados: el estudio incluyó a 424 adultos mayores, el 84.4% (n = 358) de ellos menores de 80 años y el 15.6% (n = 66) con más de 80 años. La ingesta de energía y proteínas fue insuficiente tanto para jóvenes adultos como para los más ancianos. El consumo de vitaminas y minerales ha sido insuficiente en todos los adultos mayores a excepción del hierro, que presentaba una ingesta excesiva. Hubo una diferencia estadísticamente significativa entre las personas de edad y mayores sólo en cuanto al consumo de lípidos y vitamina B12. Conclusión: la mayoría de los estudios con personas mayores corrobora los resultados obtenidos en este artículo. Una ingesta inadecuada de nutrientes puede dar lugar a deficiencias nutricionales y, por lo tanto, a cambios fisiológicos y patológicos que pondrían en peligro la capacidad funcional de los ancianos. El consumo de energía y de macronutrientes resultó insuficiente tanto para los ancianos como para los ancianos más longevos. Además, el consumo de vitaminas y

    The okapi is an endangered, evolutionarily distinctive even-toed ungulate classified within the giraffidae family that is endemic to the Democratic Republic of Congo. The okapi is currently under major anthropogenic threat, yet to date nothing is known about its genetic structure and evolutionary history, information important for conservation management given the species' current plight. The distribution of the okapi, being confined to the Congo Basin and yet spanning the Congo River, also makes it an important species for testing general biogeographic hypotheses for Congo Basin fauna, a currently understudied area of research. Here we describe the evolutionary history and genetic structure of okapi, in the context of other African ungulates including the giraffe, and use this information to shed light on the biogeographic history of Congo Basin fauna in general. Using nuclear and mitochondrial DNA sequence analysis of mainly non-invasively collected samples, we show that the okapi is both highly genetically distinct and highly genetically diverse, an unusual combination of genetic traits for an endangered species, and feature a complex evolutionary history. Genetic data are consistent with repeated climatic cycles leading to multiple Plio-Pleistocene refugia in isolated forests in the Congo catchment but also imply historic gene flow across the Congo River.

    Haemosporida parasites of even-toed ungulates are diverse and globally distributed, but since their discovery in 1913 their characterization has relied exclusively on microscopy-based descriptions. In order to bring molecular approaches to bear on the identity and evolutionary relationships of ungulate malaria parasites, we conducted Plasmodium cytb-specific nested PCR surveys using blood from water buffalo in Vietnam and Thailand, and goats in Zambia. We found that Plasmodium is readily detectable from water buffalo in these countries, indicating that buffalo Plasmodium is distributed in a wider region than India, which is the only area in which buffalo Plasmodium has been reported. Two types (I and II) of Plasmodium sequences were identified from water buffalo and a third type (III) was isolated from goat. Morphology of the parasite was confirmed in Giemsa-reagent stained blood smears for the Type I sample. Complete mitochondrial DNA sequences were isolated and used to infer a phylogeny in which ungulate malaria parasites form a monophyletic clade within the Haemosporida, and branch prior to the clade containing bird, lizard and other mammalian Plasmodium. Thus it is likely that host switching of Plasmodium from birds to mammals occurred multiple times, with a switch to ungulates independently from other mammalian Plasmodium. PMID:26996979

    This study was conducted to evaluate the prevalence of antibodies against Borrelia bugdorferi (Bb) s.l. and tick-borne encephalitis virus (TBEV) in zoo animals in the Czech Republic. We collected 133 serum samples from 69 animal species from 5 zoos located in different parts of the country. The samples were obtained from even-toed ungulates (n=78; 42 species), odd-toed ungulates (n=32; 11 species), carnivores (n=13; 9 species), primates (n=2, 2 species), birds (n=3; 2 species), and reptiles (n=5; 3 species). A high antibody prevalence (60%) was observed for Bb s.l. On the other hand, only two animals had TBEV-specific antibodies: a markhor (Capra falconeri) and a reindeer (Rangifer tarandus), both from the same zoo, located in an area endemic for TBEV. Both of these animals were also positive for Bb s.l. antibodies. Our results indicate that a high number of animal species in the Czech zoos were exposed to Bb s.l. and that TBEV infection occurred at least in one of the investigated zoos. Considering the pathogenic potential of these two tick-borne pathogens, clinical and serological monitoring should be continued, and therapeutic and preventive measures should be taken when necessary.

    The emergence of Cetacea in the Paleogene represents one of the most profound macroevolutionary transitions within Mammalia. The move from a terrestrial habitat to a committed aquatic lifestyle engendered wholesale changes in anatomy, physiology, and behavior. The results of this remarkable transformation are extant whales that include the largest, biggest brained, fastest swimming, loudest, deepest diving mammals, some of which can detect prey with a sophisticated echolocation system (Odontoceti - toothed whales), and others that batch feed using racks of baleen (Mysticeti - baleen whales). A broad-scale reconstruction of the evolutionary remodeling that culminated in extant cetaceans has not yet been based on integration of genomic and paleontological information. Here, we first place Cetacea relative to extant mammalian diversity, and assess the distribution of support among molecular datasets for relationships within Artiodactyla (even-toed ungulates, including Cetacea). We then merge trees derived from three large concatenations of molecular and fossil data to yield a composite hypothesis that encompasses many critical events in the evolutionary history of Cetacea. By combining diverse evidence, we infer a phylogenetic blueprint that outlines the stepwise evolutionary development of modern whales. This hypothesis represents a starting point for more detailed, comprehensive phylogenetic reconstructions in the future, and also highlights the synergistic interaction between modern (genomic) and traditional (morphological+paleontological) approaches that ultimately must be exploited to provide a rich understanding of evolutionary history across the entire tree of Life.

However, epidemiological studies, in most cases, have limited their research questions to determinants of health outcomes.

    ABSTRACTThis article provides a review of immunity, diagnosis, and clinical aspects of rotavirus disease. It also informs about the changes in epidemiology of diarrheal disease and genetic diversity of circulating group A rotavirus strains following the introduction of vaccines. Group A rotavirus is the major pathogen causing gastroenteritis in animals. Its segmented RNA genome can lead to the emergence of new or unusual strains in human populations via interspecies transmission and/or reassortment events.RESUMOEste artigo fornece uma revisão sobre imunidade, diagnóstico e aspectos clínicos da doença causada por rotavírus. Também aponta as principais mudanças no perfil epidemiológico da doença diarreica e na diversidade genética das cepas circulantes de rotavírus do grupo A, após a introdução vacinal. O rotavírus do grupo A é o principal patógeno associado à gastroenterite em animais. Seu genoma RNA segmentado pode levar ao surgimento de cepas novas ou incomuns na população humana, por meio de transmissão entre espécies e eventos de rearranjo. PMID:27462899

    Foot and mouth disease (FMD) is a highly contagious viral disease of even-toed ungulates and is endemic in most of the tropics. A cross-sectional study using a stratified, two-stage random sample design was undertaken in the Adamawa Province of Cameroon. The objectives were to measure the reported herd-level prevalence of FMD and a range of husbandry practices important for its transmission. The owner-reported prevalence for the previous 12 months was 57.9% (50.4-65.4%), although there was a significant variation across the Province. During the previous dry season, 46.5% (38.6-54.4%) of herds had gone on transhumance. Herds had high numbers of contacts with other herds while on transhumance (98.6%), at pasture (95.8%) and at night (74.4%), with medians of 7-10, 4-6 and 1-3 daily contacts, respectively. The high level of endemic FMD and potential for disease spread presents a significant challenge for control and eradication. Locally sustainable methods need to be developed upon which larger regional control programmes could be built in the future. PMID:14690088

    El plasma de la corona solar es un buen indicador de las líneas de fuerza del campo magnético. Por lo tanto, el análisis de estructuras coronales cuasiestacionarias en la corona da importante información sobre el campo magnético y la actividad asociada. Se trata de poner límites a los modelos teóricos existentes mediante el estudio de distintas estructuras en la corona interior. En agosto de 1997 comenzó a operar el coronógrafo solar (MICA) en El Leoncito como parte del Observatorio Solar Alemán-Argentino. Desde su instalación obtiene imágenes de la corona solar (1.05 a 2.0 radios solares) en 2 líneas espectrales correspondientes a la emisión de Fe XIV y Fe X. El instrumento puede obtener imágenes cada minuto por lo que es ideal para estudiar procesos rápidos. Presentamos observaciones recientes que muestran la capacidad del coronógrafo así como la evolución de algunos eventos dinámicos observados por MICA.

    Resumen A finales de la década de los cincuenta, Estados Unidos permitía la entrada de aproximadamente medio millón de inmigrantes mexicanos al año, de los cuales 450.000 entraban con visados de trabajo temporal y 50.000 llegaban con visados de residentes permanentes. A mediados de los años sesenta, los cambios en la política migratoria de Estados Unidos realizados en nombre de los derechos civiles redujeron drásticamente las oportunidades de entrada legal a Estados Unidos. Se eliminaron los visados de trabajo temporal y se limitaron los visados de residentes a 20.000 por año. Con las oportunidades de entrada legal restringidas, los flujos migratorios ya establecidos simplemente continuaron, fuera de los límites legales, dando comienzo a una inesperada reacción en cadena de eventos que culminaron en una guerra total contra los inmigrantes y el rápido crecimiento -sin precedentes- de población residente no autorizada en Estados Unidos. El presente artículo demuestra que el aumento de inmigración indocumentada en los Estados Unidos y el crecimiento de la población sin papeles son un producto de políticas migratorias y fronterizas mal concebidas.

    Introducción: El temblor puede ser un desorden incapacitante y el tratamiento de primera línea para estos pacientes es farmacológico. Sin embargo, este tratamiento puede llevar a una reducción satisfactoria del temblor en sólo el 50% de los pacientes con temblor esencial. La talamotomía era el tratamiento de elección para el temblor refractario al tratamiento médico hasta que comenzó a utilizarse la estimulación cerebral profunda (ECP) del núcleo ventral intermedio (Vim) del tálamo. En la actualidad, raramente se realiza la talamotomía. Métodos: Este artículo es una revisión no sistemática de las indicaciones, resultados, parámetros de programación y técnica quirúrgica de la ECP del Vim para el tratamiento del temblor. Resultados: Aunque los resultados clínicos son similares usando la talamotomía o la ECP del Vim, la primera causa más efectos adversos que la última. Además, la ECP puede ser usada bilateralmente, mientras que la talamotomía tiene un alto riesgo de causar disartria cuando se realiza de ambos lados. La ECP del Vim logró una adecuada mejoría del temblor en varias series de pacientes con temblor causado por temblor esencial, enfermedad de Parkinson o esclerosis múltiple. Además del Vim, hay otros blancos que están siendo usados por varios autores, tales como la zona incerta y las radiaciones prelemniscales. Conclusión: La ECP del Vim es un tratamiento útil para el temblor incapacitante refractario al tratamiento médico. Es esencial realizar una precisa selección de pacientes, así como utilizar una técnica quirúrgica correcta. Aún se desconoce el mejor blanco estereotáctico para el temblor, aunque el Vim es el más usado. PMID:25165613

    RESUMENFundamento. Mostrar las desigualdades en mortalidad prematura según indicadores de bienestar material en Navarra.Método. Todos los ciudadanos menores de 75 años residentes en Navarra en 2001 fueron seguidos durante 7 años para conocer su estado vital. El indicador de posición socioeconómica usado ha sido la superficie de la casa y el número de vehículos del hogar. Se han estimado las tasas de mortalidad general y por causa de muerte ajustadas por edad según estos indicadores.Resultados. La razón de tasas por todas las causas de muerte en las categorías inferiores es según la superficie de la vivienda de 1,14 (IC 95%: 1,05-1,24) y 1,25 (IC 95%: 1,18-1,32) en mujeres y hombres respectivamente y de 1,46 (IC 95%: 1,36-1,57) y 1,97 (IC 95%: 1,89-2,05) según el número de vehículos. El sida es la causa de muerte que presenta una mayor diferencia en las tasas de mortalidad entre las personas con menor y mayor bienestar material. Otras causas de muerte con elevada diferencia en las tasas de mortalidad son las enfermedades digestivas y la diabetes mellitus en mujeres y las enfermedades del aparato digestivo y respiratorio en hombres.Conclusiones. La tasa de mortalidad en la población navarra muestra un gradiente inverso con el bienestar material, a excepción de algunas localizaciones de cáncer. Este gradiente es mayor entre los hombres que entre las mujeres.Palabras clave. Mortalidad prematura. Bienestar material. PMID:27125605

  19. Planning for Adaptation to Climate Change in the City of Chicago

    Wuebbles, D. J.; Hayhoe, K.; Coffee, J.; McGraw, J.; Parzen, J.

    2008-12-01

    Under Mayor Richard M. Daley's leadership, the City of Chicago initiated the Chicago Climate Action Plan (CCAP) to better understand local implications of global climate change in both higher and lower emissions scenarios, reduce greenhouse gas emissions, and implement programs to build future climate change resilience. The City approached this work not only as a way to make Chicago more adaptable in the future, but also to improve Chicago's quality of life today. The Chicago Climate Action Plan adopted stresses the importance of both reducing greenhouse gas emissions in Chicago and preparing for climate changes that may be unavoidable. Building off of the City's significant environmental programs and projects, and based on our analyses of the climate effects and impacts that improved the scientific understanding of future climate change impacts on Chicago, the City then developed a set of climate change adaptation strategies, resulting in the City of Chicago Climate Change Adaptation Summary. This document includes prioritization of climate change adaptations based on relative risk as well as framework strategies for those tactics categorized as "must do/early action." In early 2008, The Mayor's Office asked five Commissioners from its Green Steering Committee to chair adaptation work groups including: extreme heat; extreme precipitation; buildings, infrastructure and equipment; ecosystems; and leadership, planning and communications. Working with staff from relevant departments, sister agencies and other stakeholders, these work groups developed 39 basic adaptation work plans, including plans for enhancing the City's existing projects and programs that relate to climate change adaptation. Climate change adaptation work will be on-going in City Departments under the Mayor's Office leadership. The City intends to continually monitor and improve its response to climate change, resulting in an improved quality of life for Chicago residents.

     Introducción: obesidad e inactividad física son importantes factores de riesgo para el desarrollo de hipertensión en adultos. No obstante, hay poca evidencia sobre el efecto de estos factores de riesgo en el desarrollo de hipertensión en población infantil. Objetivo: investigar la asociación del estado nutricional, niveles de actividad física y etnicidad con niveles de hipertensión en escolares entre 6 y 13 años de edad. Métodos: un total de 418 escolares de ascendencia étnica europea (n = 311) y mapuche (n = 107) fueron participantes de este estudio transversal. Se midió el peso, talla, índice de masa corporal (IMC) y presión arterial, utilizando protocolos estandarizados. Resultados: no se encontraron diferencias significativas en IMC, estado nutricional y presión arterial entre niños con ascendencia europea y mapuche. No obstante, la prevalencia de prehipertensión (21,3% vs. 11,1%) e hipertensión (28,9% vs. 18,6%) fue significativamente mayor en escolares mapuches en comparación con europeos, respectivamente. Escolares con ascendencia mapuche tienen un mayor riesgo de desarrollar prehipertensión o hipertensión que escolares con ascendencia europea (OR: 1,92 [1,19 a 3,06], p < 0,01). La prevalencia de hipertensión aumenta significativamente en ambos grupos étnicos con el incremento de IMC y bajos niveles de actividad física. Conclusiones: el riesgo de desarrollar prehipertensión o hipertensión es mayor en población infantil ascendiente de mapuches que ascendiente de europeos y este riesgo se ve acentuado con el incremento de obesidad y bajos niveles de actividad física.

    Etchegoyen, A.

    Hace ya más de 30 años en Volcano Ranch, EE.UU., un extenso chubasco cósmico (ECC) fue detectado con energía en exceso de 1020 eV. Desde entonces, observatorios ubicados en Haverah Park del Reino Unido, Yakutsk de Rusia, AGASA de Japón y Dugway de EE.UU. también han observado ECC con energías mayores que 1020 eV. Poco se sabe de dichos rayos, y en particular cuál es la naturaleza del primario, de dónde provienen, y cómo son acelerados, pero su naturaleza ultrarelativista excluye la mayoría de las respuestas dejando sólo algunas plausibles de ser investigadas experimentalmente. Grupos de científicos de 20 países están trabajando con el fin de construir dos arreglos de detectores gigantes, uno en cada hemisferio a lo largo de 3000 km2 c/u. Dichas dimensiones son necesarias debido al flujo estimado de 1 rayo cósmico/centuria/km2/sr. La sede del Observatorio del Sur es la Argentina. El proyecto fue nombrado Pierre Auger en conmemoración del célebre físico francés que detectó por primera vez chubascos cósmicos en 1938. El proyecto focaliza su interés en rayos cósmicos con energías mayores que 1020 eV.

    El objetivo del presente trabajo fue analizar la situación epidemiológica de la tuberculosis (TB) en la Región Sanitaria V (RSV), provincia de Buenos Aires. El estudio de tendencia permitió conocer un valor promedio de las variaciones de la tasa de incidencia (TI), calculadas por regresión lineal simple y expresadas como variación anual promedio (VAP). Se analizaron el número de casos notificados y TI por 100 000 habitantes de todas las formas de TB, los casos de TB pulmonar (TBP) y TBP confirmados por bacteriología, total casos por grupos de edad: 0 – 14; 15 – 29 y mayores de 64 años, entre el 1° de enero de 2000 al 31 de diciembre de 2011. La declinación de la TI fue menor al 5% para todas las formas de TB e inferior en las TBP confirmadas bacteriológicamente. Los casos de TBP y TI más elevadas, se concentraron en el grupo de 15 a 29 años, con tendencia estable o ligeramente ascendente de la TI en la TBP bacilífera. El mismo comportamiento presentaron los casos de TBP infantil con confirmación bacteriológica. La mayor velocidad de descenso en la TI de la TBP se produjo en este grupo de edad, mientras que en mayores de 64 años, el descenso fue sostenido en el tiempo. La TB persiste como un riesgo de salud en la RSV, con casos en edades jóvenes, por lo que sigue siendo necesario fortalecer el control de la TB en esta región. PMID:26117604

    We explore the use of collocated GPS and seismic sensors for earthquake monitoring and early warning. The GPS and seismic data collected during the 2011 Tohoku-Oki (Japan) and the 2010 El Mayor-Cucapah (Mexico) earthquakes are analyzed by using a tightly-coupled integration. The performance of the integrated results is validated by both time and frequency domain analysis. We detect the P-wave arrival and observe small-scale features of the movement from the integrated results and locate the epicenter. Meanwhile, permanent offsets are extracted from the integrated displacements highly accurately and used for reliable fault slip inversion and magnitude estimation. PMID:24284765

  6. From protest to programs: neighborhood associations in a Brazilian municipality.

    The examples of community participation and organization in Brazil reflect the benefits to health and education programs and land entitlement. The community and government were working together toward self-improvement. An alliance was formed between neighborhood groups and a reform mayor. The result was an end to clientelism, stronger community organization, and local participation in designing and implementing development programs. The neighborhood groups were located in Cambe, which is a region located within the metropolitan area of Londrina, the 3rd largest city in southern Brazil. Mechanization of agriculture and extensive cattle ranching had caused migration into the area. Population increased 60% during the 1980s. The poorest neighborhoods were Jardim Tupy, Santo Amaro, and Novo Bandeirantes. Jardim Tupy was the poorest, and in 1980 a neighborhood association was formed to demand infrastructure and public services. The clientelism mayor and national government refused aid. When the association sued over a motor vehicle accident involving farm workers living in the community and won, there was momentum to change city hall. Support was given to the reform mayor who won and agreed to community demands for a community garden. The garden became a model for 14 others in Cambe and led to a strong neighborhood association which learned the strength of unity. The mayor rewarded good neighborhood organization with increases in public goods and services. The Catholic Church became involved in Jardim Tupy with a Pastoral of the Child program to reduce infant and child mortality rates. Health improvements in the community are attributed to the neighborhood association, the Pastoral of the Child, the local Catholic parish, and a thaw in the relationship with local government. The residents learned the limits of local government and the lessons of self-help. Santo Amaro, while not as well organized as Jardim Tupy, was successful at overcoming the lack of resources. novo

    This year marks the 20th anniversary of the first definitive detection of an exoplanet orbiting a Sun-like star by Mayor and Queloz (1995). Almost 2000 exoplanets have been discovered since this breakthrough, but many fundamental questions remain open despite the enormous progress: How common are analogues of the Solar System? How do planets form and evolve? What is the relationship between stars and planets? We are observing stars that are near-perfect matches to the Sun to provide new insights into the above questions, thus exploring the planet-star connection with unprecedented precision.

    1982-01-01

    Band model theories are used to calculate the transmission of the methane spectrum. In a band model the monochromatic absorption coefficient over a small wavelength interval is replaced, and an average pressure coefficient is introduced. Two main types of band models were developed. The first is the 'regular' band model, in which the lines in a band are presumed evenly spaced; this is also called the Elsasser band model. In the second type of band model, the lines are randomly spaced; this is often referred to as the Mayor-Goody band model. The methane spectrum is sufficiently irregular that the second band model, the irregular band model, should apply.

    New paleomagnetic data from Permo-Triassic and Late Cretaceous rocks yield a consistent trend of vertical-axis-tectonic-rotations which are consistent with the Central Andean Rotation Pattern (CARP). However, three sites in the Tuina Formation and one site in the Purilactis Group record large rotations (80°). These mayor rotations are probably due to dextral-transpressive deformation occurring in close relation with the Incaic tectonic phase. Consequently, it is possible to infer that previous tectonic phases Peruvian and K-T would not have produced significant tectonic rotations in the area.

  7. Observações das explosões cósmicas de raios gama GRB021004 e GRB021211 com o satélite HETE

    NASA Astrophysics Data System (ADS)

    2003-08-01

    O High Energy Transient Explorer (HETE) é o primeiro satélite inteiramente dedicado ao estudo das explosões cósmicas de raios gama (ECRGs). Lançado em 9 de outubro de 2000, o HETE possui instrumentação capaz de observar as ECRGs desde o UV até raios gama e localizá-las com precisão de ~ 1-10 minutos de arco. As localizações das ECRGs detectadas são disseminadas rapidamente (em alguns segundos) pela Internet através de uma rede de estações de recepção ao longo do equador. A participação brasileira nesse projeto se dá através da montagem e operação de uma estação de recepção em Natal, RN, e da participação na equipe científica da missão. Neste trabalho são apresentados resultados da observação pelo HETE de duas ECRGs: GRB 021004 e GRB 021211. A GRB021004 foi detectada em raios gama pelo HETE em 4 de outubro de 2002 e localizada em raios-X em apenas 48 s, quando a emissão de raios gama ainda estava se processando. A explosão, relativamente brilhante e longa, durou aproximadamente 100 s. Um transiente óptico de magnitude 15 foi detectado no local da explosão nove minutos após o evento, e observações realizadas após 7 horas determinaram um desvio para o vermelho de absorção de 1,6. O GRB021004 foi o burst mais bem observado até o momento e suas observações em vários comprimentos de onda têm sido fundamentais para o aprimoramento dos modelos de ECRGs. O GRB21211, um burst brilhante e rico em raios-X, foi detectado em 11 de dezembro de 2002 e localizado em raios-X em 22 s após o início do evento. A duração do burst foi de 2,3 s em altas energias (85 a 400 keV) e de 8,5 s em baixas energias (2 a 10 keV). Caso essa explosão não tivesse sido rapidamente localizada pelo HETE, ela teria sido classificada como "opticamente escura", já que o transiente óptico decaiu rapidamente de R < 14 a R»19 dentro dos primeiros 20 minutos e já estava mais fraco do que R»23 depois de 24 horas da ocorrência do burst.

    The present study describes the organization of the orexinergic (hypocretinergic) neurons in the hypothalamus of the giraffe and harbour porpoise – two members of the mammalian Order Cetartiodactyla which is comprised of the even-toed ungulates and the cetaceans as they share a monophyletic ancestry. Diencephalons from two sub-adult male giraffes and two adult male harbour porpoises were coronally sectioned and immunohistochemically stained for orexin-A. The staining revealed that the orexinergic neurons could be readily divided into two distinct neuronal types based on somal volume, area and length, these being the parvocellular and magnocellular orexin-A immunopositive (OxA+) groups. The magnocellular group could be further subdivided, on topological grounds, into three distinct clusters – a main cluster in the perifornical and lateral hypothalamus, a cluster associated with the zona incerta and a cluster associated with the optic tract. The parvocellular neurons were found in the medial hypothalamus, but could not be subdivided, rather they form a topologically amorphous cluster. The parvocellular cluster appears to be unique to the Cetartiodactyla as these neurons have not been described in other mammals to date, while the magnocellular nuclei appear to be homologous to similar nuclei described in other mammals. The overall size of both the parvocellular and magnocellular neurons (based on somal volume, area and length) were larger in the giraffe than the harbour porpoise, but the harbour porpoise had a higher number of both parvocellular and magnocellular orexinergic neurons than the giraffe despite both having a similar brain mass. The higher number of both parvocellular and magnocellular orexinergic neurons in the harbour porpoise may relate to the unusual sleep mechanisms in the cetaceans. PMID:22683547

    Nearly all living artiodactyls (even-toed ungulates) possess a derived cranial arterial pattern that is highly distinctive from most other mammals. Foremost among a suite of atypical arterial configurations is the functional and anatomical replacement of the internal carotid artery with an extensive, subdural arterial meshwork called the carotid rete. This interdigitating network branches from the maxillary artery and is housed within the cavernous venous sinus. As the cavernous sinus receives cooled blood draining from the nasal mucosa, heat rapidly dissipates across the high surface area of the rete to be carried away from the brain by the venous system. This combination yields one of the most effective mechanisms of selective brain cooling. Although arterial development begins from the same embryonic scaffolding typical of mammals, possession of a rete is typically accompanied by obliteration of the internal carotid artery. Among taxa with available ontogenetic data, the point at which the internal carotid obliterates is variable throughout development. In small-bodied artiodactyls, the internal carotid typically obliterates prior to parturition, but in larger species, the vessel may remain patent for several years. In this study, we use digital anatomical data collection methods to describe the cranial arterial patterns for a growth series of giraffe (Giraffa camelopardalis), from parturition to senescence. Giraffes, in particular, have unique cardiovascular demands and adaptations owing to their exceptional body form and may not adhere to previously documented stages of cranial arterial development. We find the carotid arterial system to be conserved between developmental stages and that obliteration of the giraffe internal carotid artery occurs prior to parturition. PMID:26925324

    Wildlife incidents with aircraft cost the United States (U.S.) civil aviation industry >US1.4 billion in estimated damages and loss of revenue from 1990 to 2009. Although terrestrial mammals represented only 2.3 % of wildlife incidents, damage to aircraft occurred in 59 % of mammal incidents. We examined mammal incidents (excluding bats) at all airports in the Federal Aviation Administration (FAA) National Wildlife Strike Database from 1990 to 2010 to characterize these incidents by airport type: Part-139 certified (certificated) and general aviation (GA). We also calculated relative hazard scores for species most frequently involved in incidents. We found certificated airports had more than twice as many incidents as GA airports. Incidents were most frequent in October ( n = 215 of 1,764 total) at certificated airports and November ( n = 111 of 741 total) at GA airports. Most (63.2 %) incidents at all airports ( n = 1,523) occurred at night but the greatest incident rate occurred at dusk (177.3 incidents/hr). More incidents with damage ( n = 1,594) occurred at GA airports (38.6 %) than certificated airports (19.0 %). Artiodactyla (even-toed ungulates) incidents incurred greatest (92.4 %) damage costs ( n = 326; US51.8 million) overall and mule deer ( Odocoileus hemionus) was the most hazardous species. Overall, relative hazard score increased with increasing log body mass. Frequency of incidents was influenced by species relative seasonal abundance and behavior. We recommend airport wildlife officials evaluate the risks mammal species pose to aircraft based on the hazard information we provide and consider prioritizing management strategies that emphasize reducing their occurrence on airport property.

    Growing morphological and molecular evidence indicates that the porpoises, dolphins, and whales evolved within the even-toed ungulates, formerly known as Artiodactyla. These animals are now grouped in the Cetartiodactyla. We evaluated the antigenic similarity of the immunoglobulin G (IgG) molecules of 15 cetacean species and the domestic cow. The similarity was scored using three distinct antibodies raised against bottlenose dolphin (Tursiops truncatus) IgG in a Western blot, an indirect enzyme-linked immunosorbent assay (ELISA), and a competitive ELISA format. A score was generated for the genetic distance between each species and T. truncatus using the cytochrome b sequence. Each antibody displayed a distinct pattern of reactivity with the IgG antibodies of the various species. The monoclonal antibody (MAb) specific for the gamma heavy chain of T. truncatus was reactive with all monodontids, delphinids, and phocoenids. The light-chain-specific MAb reacted with IgG of delphinoid and phocoenid species and one of the two mysticete species tested. The polyclonal antibody was broadly cross-reactive across all cetaceans and the domestic cow. Using the MAb specific for the gamma heavy chain, the degree of IgG cross-reactivity ranged from less than 17% for the mysticetes to 106% for killer whale Orcinus orca. The IgG in beaked whale and baleen whale sera was significantly less cross-reactive with bottlenose dolphin IgG than sera from other toothed whales. A strong negative correlation was demonstrated between antigenic cross-reactivity of IgG molecules and the genetic distance of their hosts. The data generated will be useful for the development of clinical serodiagnostics in diverse cetacean species. PMID:18768672

    Resumen Este artículo compara los resultados económicos entre los inmigrantes latinoamericanos en España y Estados Unidos. Detectamos un efecto de selección por el que la mayoría de los inmigrantes latinoamericanos en España proceden de Sudamérica de un entorno de clases medias, mientras la mayoría de los inmigrantes que van a los Estados Unidos son centroamericanos de clase baja. Este efecto de selección explica las diferencias transnacionales en la probabilidad de empleo, logro ocupacional y salarios obtenidos. A pesar de las diferencias en los orígenes y las características de los latinoamericanos en ambos países, los factores demográficos, humanos y de capital social parecen operar de forma similar en ambos países; y cuando los modelos se estiman separadamente por estatus legal, descubrimos que los efectos se acentúan más entre los inmigrantes irregulares cuando se los compara con los regulares, especialmente en Estados Unidos.

    The 1993 National Population Week opened in the commune of Rutare on August 2 and ended in Gikongoro in the commune of Rwamiko on August 6. Its goal was to sensitize all levels of the population to Rwanda's demographic problems through an IEC (information, education, communication) program while respecting the individual liberty, and the moral and religious beliefs of couples. On the first day of the population education campaign, the mayors of each commune along with its elite presided over a meeting to discuss implementation of the campaign, the sociodemographic situation at the commune level (especially at the household level), and the importance of family planning in family health. During August 2-5 at the commune level, the communal elite and the abakangurambagas presided over sensitization meetings, conference-debates, educational discussions, home visits, theatrical sessions, songs and dances, orientation to health centers, and recruitment of family planning acceptors. On the last day, development technicians working in the commune, teachers, students, religious leaders, abakangurambagas, political party leaders, and mass media journalists, all of whom took part in the week's activities, met at the communal office to evaluate the week's activities and to amass resolutions and recommendations. The mayor closed the 1993 edition of the National Population Week after the evaluation. PMID:12287364

    Police brutality, a longstanding civil rights issue, has returned to the forefront of American public debate. A growing body of public health research shows that excessive use of force by police and racial profiling have adverse effects on health for African Americans and other marginalized groups. Yet, interventions to monitor unlawful policing have been met with fierce opposition at the federal, state, and local levels. On April 30, 2015, the mayor of Newark, New Jersey signed an executive order establishing a Civilian Complaint Review Board (CCRB) to monitor the Newark Police Department (NPD). Using a mixed-methods approach, this study examined how advocates and government actors accomplished this recent policy change in the face of police opposition and after a 50-year history of unsuccessful attempts in Newark. Drawing on official public documents, news media, and interviews conducted in April and May 2015, I propose that: (1) a Department of Justice investigation of the NPD, (2) the activist background of the Mayor and his relationships with community organizations, and (3) the momentum provided by the national Black Lives Matter movement were pivotal in overcoming political obstacles to reform. Examining the history of CCRB adoption in Newark suggests when and where advocates may intervene to promote policing reforms in other US cities. PMID:26661578

    This study investigates symbolic meanings found in the Sunda ethnic clothing, particularly the Menak Priangan clothing. This study aims to uncover and document those symbolic meanings found in the Menak Priangan clothing as an effort to develop Sunda cultural artefacts of West Java. This study on Menak Priangan clothing applies ethnography (visual) and aesthetic methods. The visual method is utilized in order to uncover local cultural (Sunda) values found in Menak Priangan clothing visualization, including: design, model, name, and representing colours, which then directed towards local Sundanese aesthetic concepts living within the Priangan community. Furthermore, aesthetic method is used to explore role of aesthetic values in empowering visual cultural values within certain community, particularly Sunda aesthetic values. The study results show that since the 19th century, Sunda ethnic clothing was limited to Priangan Sunda only, while traditional clothing wearing by Priangan people reflects their social strata, consisting of: a. Menak Gede (Menak pangluhurna: mayor), bearing raden title, b. Menak Leutik/Santana (mayor assistant), titles: asep, mas, agus, ujang, (Nyimas for woman), c. Somah/Cacah: ordinary people/lower class. Clothing is a cultural phenomenon within certain culture reflecting such society experiences. For Menak people, clothing and its accessories have important meanings. They wear such traditional clothing and accessories as a symbol of power they have within bureaucratic structure and as a symbol of social status they bear within traditional community structure.

    Dr Thomas Stockmann, the protagonist of Ibsen's play, An Enemy of the People, discovers a serious health threat in the Baths of his Norwegian town. The Baths have been marketed as a health resort to lure visitors. Dr Stockmann alerts officials about the problem and assumes that they will close the Baths until it is corrected. He is met with fierce resistance, however. His brother, the town's mayor, favors keeping the Baths open and correcting the problem gradually. He advances multiple arguments that appeal to the economic interests of the town and Thomas's role-related obligation as a citizen. His wife, Katherine, wants him to cooperate with the mayor. She marshals several arguments that appeal to his obligations as a father. This paper reconstructs and examines the competing arguments, shows how Ibsen's play has both contemporary relevance and moral depth, and demonstrates how Dr Stockmann's responses can be interpreted as an argument that complying with his duties to protect the public health do not force him to renege on his core commitments as a parent and as a citizen.

Se aplicaron los calculos al intervalo de densidades n = lO to , forrespondiendo a la fase isotermica de contracci6n de nubes. A lo largo de esta fase en el colap- so, la temperatura es por lo tanto constante, en donde se alcanza T Q lOKpara nubes de metalicidad solar y T 100 K para nubes de baja metalicidad. El tamano final del grano es mayor para las mayores metali- cidades. ABSTRACT. A process of grain coagulation in collapsing clouds of different metallicities is considered. The calculations are applied to the density range n = 1O to , corresponding to the isothermal phase of cloud contraction. Along this phase in the collapse, the temperature is thus a constant, where T % 10 K for solar-metallicity clouds, and T % 100 K for low metallicity clouds is reached. The final grain size is larger for the higher metallicities. Keq : INTERSTELLAR-CLOUDS - INTERSTELLAR-CRAINS

    For the first time results of an archaeomagnetic study of mural paintings and unburned lime-plasters from Mesoamerica are presented. The magnetic measurements show that at least four murals (sites: Cacaxtla, Cholula and Templo Mayor) retain a remanent magnetization carried by a mixture of hematite and magnetite grains. In most specimens, a characteristic magnetization is successfully isolated by alternating field demagnetization. The mean directions are reasonably well determined for each murals and within the range of secular variation during the last centuries. Studied Mesoamerican murals apparently retain the direction of the magnetic field at the time they were painted and are therefore an invaluable source of information concerning its secular variation. Lime-plaster samples were selected from two archaeological excavation projects in the Teopancazco residential compound of Teotihuacan and the large multi-stage structure of Templo Mayor in Tenochtitlan, where chronological information is available. The intensity of remanent magnetization and low-field susceptibility are weak reflecting low relative content of magnetic minerals. NRM directions are well grouped and alternating field demagnetization shows single or two-component magnetizations. Rock-magnetic experiments point to fine-grained titanomagnetites with pseudo-single domain behavior. Anisotropy of magnetic susceptibility measurements document a depositional fabric, with normal to free-surface minimum AMS axes. Characteristic mean site directions were correlated to the paleosecular variation curve for Mesoamerica. Our results suggest that archaeomagnetic dating can be applied to mural paintings and lime-plasters, which are materials widely employed in Mesoamerica.

    Este artículo documenta una respuesta agregada negativa del logro educativo superior (más de 12 años de escolaridad) en México a la recesión de 1982–83 y el estancamiento que le siguió. La respuesta no fue homogénea entre géneros, regiones y entornos familiares. Los hombres experimentaron una caída en el logro mientras que las mujeres experimentaron un crecimiento más lento. En promedio, los estados con un mayor logro antes del choque experimentaron mayores caídas. La respuesta entre distintos entornos familiares no presenta un patrón claro. Sin embargo, el efecto negativo en el logro se observa incluso entre hermanos. La evidencia sugiere una historia por el lado de la demanda: la caída en el ingreso de los hogares parece ser el determinante de la caída/desaceleración del logro educativo superior. La conclusión es que la recesión y la falta de crecimiento que le siguió tuvieron un efecto negativo importante y duradero en la formación de capacidades en México. PMID:25328251

    Kapitza-Dirac-Talbot-Lau interferometry (KDTLI) has recently been established as an ideal method to perform quantum matter wave experiments with large, highly polarizable molecules in an unprecedented mass range of beyond 1000 atomic mass units [1]. Since the interference visibility reveals important information on the properties of the examined particles, such as their mass and polarizability, we identified KDTLI as a valuable tool for precision metrology. We demonstrate that quantum interferometry can therefore also serve as a powerful complement to mass spectrometry [2], in particular in cases where fragmentation may occur in the detector. Our new method is applicable to a wide range of molecules and is particularly valuable for characterizing neutral molecular beams. [1] S. Gerlich, L. Hackerm"uller, K. Hornberger, A. Stibor, H.

    Cancer cell metabolism differs from that of non-transformed cells in the same tissue. This specific metabolism gives tumor cells growing advantages besides the effect in increasing anabolism. One of these advantages is immune evasion mediated by a lower expression of the mayor histocompatibility complex class I molecules. The extracellular-signal-regulated kinase-5 regulates both mayor histocompatibility complex class I expression and metabolic activity. However, the mechanisms underlying are largely unknown. We show here that extracellular-signal-regulated kinase-5 regulates the transcription of the NADH(+)-dependent histone deacetylase silent mating type information regulation 2 homolog 1 (Sirtuin 1) in leukemic Jurkat T cells. This involves the activation of the transcription factor myocyte enhancer factor-2 and its binding to the sirt1 promoter. In addition, extracellular-signal-regulated kinase-5 is required for T cell receptor-induced and oxidative stress-induced full Sirtuin 1 expression. Extracellular-signal-regulated kinase-5 induces the expression of promoters containing the antioxidant response elements through a Sirtuin 1-dependent pathway. On the other hand, down modulation of extracellular-signal-regulated kinase-5 expression impairs the anti-oxidant response. Notably, the extracellular-signal-regulated kinase-5 inhibitor BIX02189 induces apoptosis in acute myeloid leukemia tumor cells without affecting T cells from healthy donors. Our results unveil a new pathway that modulates metabolism in tumor cells. This pathway represents a promising therapeutic target in cancers with deep metabolic layouts such as acute myeloid leukemia. PMID:24880091

    We examine shear velocity anisotropy in the Yuha Desert, California using aftershocks of the 2010 M7.2 El Mayor-Cucapah earthquake. The Yuha Desert is underlain by a complex network of right- and left-lateral conjugate faults, some of which experienced triggered slip during the El Mayor-Cucapah earthquake. An automated method that implements multiple measurement windows and a range of bandpass filters is used to estimate the fast direction (φ) and delay time (δt) of the split shear waves. We find an average φ oriented approximately north-south suggesting it is primarily controlled by the regional maximum compressive stress direction. However, the spatial variability in φ reveals that the fault structures that underlie the Yuha Desert also influence the measured splitting parameters. We infer that the northeast- and northwest-oriented φ reflect shear fabric subparallel to the conjugate fault structures. We do not observe a simple correlation between δt and hypocentral distance. Instead, the observed spatial variation in δt suggests that near-source variation in anisotropic strength may be equal to or more important than effects local to the station. No temporal variation in splitting parameters is observed during the 70-day period following the main shock. In this region of complex faulting, we observe a spatially variable pattern of anisotropy that is both stress- and structure-controlled. This study suggests that shear fabric can form even along short, discontinuous fault strands with minimal offset.

    Introducción y desarrollo En los próximos 50 años vamos a presenciar un incremento significativo de la población mayor de 65 años y por lo tanto va a aumentar, considerablemente, el número de individuos con riesgo de desarrollar demencias neurodegenerativas, especialmente la enfermedad de Alzheimer (EA). Las estrategias actuales de tratamiento farmacológico y no farmacológico se han centrado en las fases sintomáticas de esta enfermedad y, gradualmente, vamos teniendo una mayor comprensión de los posibles factores de riesgo del síndrome clínico. Conclusiones Los estudios de neuroimagen han sido muy útiles para mostrar los cambios estructurales del envejecimiento normal y patológico, así como también los factores de riesgo para la EA. Los tratamientos apropiados de los factores de riesgo y su posible combinación con tratamientos específicos para la EA podrían prolongar el período presintomático de la EA y, por tanto, mejorar la calidad de vida y disminuir la carga para el paciente, la familia y la sociedad.

    Introducción: la desnutrición relacionada con la enfermedad (DRE) es un problema sociosanitario frecuente que afecta preferentemente a los mayores de 65 años, que aumenta la morbimortalidad y disminuye la calidad de vida.  Objetivo: estudiar la prevalencia de DRE en mayores de 65 años en diferentes centros sociosanitarios del Servicio Regional de Bienestar Social de la Comunidad de Madrid. Métodos: estudio transversal en 33 centros sociosanitarios de Madrid (6 centros de atención primaria [AP], 9 centros de mayores [CM], 9 hospitales [H] y 9 residencias [R]) seleccionados mediante muestreo polietápico. Las variables estudiadas fueron edad, sexo, nivel de dependencia según la escala de incapacidad de la Cruz Roja, motivo de ingreso y enfermedad de base, hábitat (urbano-periurbano-rural) y distribución geográfica (norte centro-sur). Como herramienta de cribado nutricional se utilizó el Mini Nutritional Assessment (MNA-cribaje) en todos los centros. En los pacientes con cribado positivo (en riesgo-desnutrición) se realizó el MNA-evaluación. El estudio estadístico se realizó con el paquete SSS 21.0 e incluyó estadística descriptiva, test de Chi-cuadrado y prueba exacta de Fisher, ANOVA de un factor, Kruskal-Wallis y análisis de regresión logística (RL) binaria univariante y multivariante. Se consideró significación estadística p < 0,05. Resultados: se reclutaron 1.103 sujetos (275 AP, 278 CM, 281 H, 269 R), edad media de 79,5 ± 8,4 años (41,2% varones, 58,8% mujeres). Los sujetos procedentes de H y R tuvieron un mayor grado de incapacidad (p < 0,001). La prevalencia global de DRE fue del 10%, encontrándose un 23,3% en riesgo de desnutrición, con diferencias entre los cuatro tipos de centros sociosanitarios (p < 0,001). El análisis univariante de RL mostró diferencia significativas en la prevalencia de desnutrición según la edad, sexo, grado de dependencia, tipo de centro sociosanitario, hábitat y zona geográfica.

    Two teachers from the town of San Pedro de Atacama, in the northern desert of the South American nation of Chile, arrive in Magdalena, New Mexico, Sunday, January 28, for a two-week visit that is part of a Sister Cities program sponsored by Associated Universities, Inc. (AUI), the nonprofit research corporation that operates the National Radio Astronomy Observatory (NRAO). They will be accompanied by their town's mayor. Myriam Nancy Rivera Mercado, Head of the high school in San Pedro, Gabriela Fernanda Rodriguez Moraleda, a tourism teacher there, and San Pedro Mayor Sandra Berna Martinez will begin a visit that includes classroom observations in the Magdalena schools, a reception hosted by the Magdalena Village Council, and a Mayor's Breakfast with Magdalena Mayor Jim Wolfe. They also will meet local residents, tour the Bosque del Apache National Wildlife Refuge with a second-grade class, visit an area ranch, tour the Very Large Array (VLA) radio telescope, and see Socorro's Community Arts Party. "These teachers will learn much about New Mexico, the United States, and our educational system, and will take this new knowledge back to their students and their community," said NRAO Education Officer Robyn Harrison. The visit is part of a Sister Cities program initiated and funded by AUI, which operates the NRAO for the U.S. National Science Foundation. Radio astronomy is a common link between San Pedro de Atacama and Magdalena. San Pedro is near the site of the Atacama Large Millimeter/submillimeter Array (ALMA), an international telescope project now under construction with funding by major partners in North America, Europe, and Japan. Magdalena is near the site of NRAO's VLA radio telescope. In Magdalena, the Village Council and Mayor Wolfe formalized their participation in the Sister Cities program last September, and San Pedro ratified the program in December. In San Pedro, the ceremony ratifying the agreement was attended by U.S. Ambassador to Chile Craig K

    Introducción: el bajo peso al nacer (BPN) es un factor de riesgo para desarrollar obesidad en la vida adulta.Objetivo: evaluar diferencias en la composición corporal de niños de entre 8 y 10 años de edad con y sin antecedente de BPN.Métodos: fue un estudio observacional, transversal comparativo. Participaron 112 niños (95 con adecuado peso al nacer [APN] y 17 con BPN). Se realizó antropometría (peso, talla, circunferencias de cintura y cadera, pliegue cutáneo de tríceps [PCT] y subescapular [PCSE]).Resultados: se encontró una prevalencia combinada del 41% para sobrepeso y obesidad en ambos grupos de estudio. El porcentaje de grasa corporal total fue menor en las niñas con BPN (no significativo); sin embargo, el indicador PCT-PCSE fue significativamente más alto (p = 0,04) que el de las niñas con APN. En contra de lo esperado, al estratificar según porcentaje de grasa y peso al nacer, se encontró que el grupo con BPN presentó un porcentaje de grasa bajo (p < 0,05) en comparación con el grupo de APN, siendo 6 veces mayor la posibilidad de que un niño con BPN presente porcentaje de grasa total bajo a esta edad.Conclusiones: a estas edades no se encontró mayor porcentaje de grasa en el grupo con BPN en comparación con el de APN; sin embargo, las niñas con BPN presentaron mayor deposición de grasa troncal que las de APN. La deposición de grasa es un indicador que hay que considerar, y no únicamente el índice de masa corporal, en la evaluación nutricia infantil. PMID:27513486

  11. Observación espectroscópica de NGC 2442

    La galaxia NGC 2442 (SAB(s)bc pec) fue observada con el telescopio de 2,15 m y el espectrógrafo REOSC del CASLEO utilizando el detector CCD Tektronix de 1024 × 1024 pixels de 24 μ m (0,26"). Las exposiciones fueron realizadas con la ranura de 3,3'' × 348'', en el plano focal, ubicadas en seis posiciones, cinco a 40o de áng. de pos. y una a 79o. La mayor parte de las exposiciones se efectuó con la red de 1200 líneas mm-1, a un ángulo de 25,53o cubriendo el rango de λλ 6200 a 6900 con dispersión de 32Å mm-1 y resolución de 2,5 Å. Las relaciones entre las intensidades de las líneas de emisión en el núcleo de NGC 2442 indican que es un LINER lo cual es compatible con la sugerencia de Shobrook de que se trataría de una galaxia Seyfert u otro tipo de galaxia activa. La temperatura y densidad electrónicas nucleares son Te ~14.000 K y Ne ~ 530 cm-3, respectivamente. Una región a 87'' al NE en cambio, donde las intensidades son también altas, presenta características espectrales típicas de una Región HII con Te ~6500 K y Ne ~10 cm-3. La correlación de las intensidades con el CO en 115 GHz y con el continuo en 843 MHz y de las velocidades ópticas con las del CO, a lo largo del eje mayor, son muy buenas. La mayor resolución angular de las observaciones, sin embargo, permite apreciar la existencia de dos componentes de velocidad en el núcleo que pueden corresponder a un anillo en rotación o a un fenómeno de expansión.

  12. Rapid Assessment and Mitigation of Cascadia Earthquakes Using the Combined PANGA and PBO Real-time GPS Networks

    Nearly 400 GPS receivers of the combined PANGA and PBO networks currently operate along the Cascadia subduction zone, all of which are high-rate and either currently or soon to be telemetered in real-time. These receivers span the M9 megathrust, M7 crustal faults beneath population centers, several active Cascades volcanoes, and a host of other hazard sources. Together these receivers enable a host of new approaches towards hazards mitigation. Data from the majority of the stations are received in real time at CWU and processed into one-second position estimates using: 1) relative positioning within several reference frames 2) absolute point positioning using streamed satellite orbit and clock corrections. While the former produces lower-noise time series, for earthquakes greater than ~M7 and ground displacements exceeding ~20 cm, point positioning provides rapid and robust estimates of the location and amplitude of both dynamic strong ground motion and permanent deformation. Estimated position streams are fed into routines that derive products relevant to rapid hazards response and mitigation: sidereal position differences and triggering detectors; “ShakeMap” and “ShiftMap” of maximum dynamic and permanent ground displacement, respectively; source magnitude and distribution of fault slip on known faults (entire megathrust; Seattle, Whidbey Island, Bainbridge, and Portland West Hills); earthquake magnitude derived from an empirical relationship between the shaking and deformation amplitude and affected regional area size; and formal surface-wave inversion estimation. For the megathrust slip estimation, we also predict sea-floor uplift along the near-coastal Cascadia region. Finally, a set of Java routines have been developed to allow any individual or agency to stream any or all of these data products onto local computers for customized analyses and triggers. The 2010 Chile and Sierra El Mayor earthquakes provided an opportunity to retroactively test some

    Pore pressure built up during an earthquake and the hazard associated with soil liquefaction present a major challenge for our society, as has been dramatically illustrated by recent large events (e.g. the 2011 Tohoku-oki, Japan, earthquake). There is consensus among scientists that a better assessment of the liquefaction risk requires a better understanding of the coupling between pore pressure and ground motion time histories. There is a basic need to investigate coupling as a function of the frequency content of the ground motion. The 2010 M7.2 El Mayor-Cucapah event has provided a remarkable opportunity to investigate and model the coupling. The event was well recorded at the NEES@UCSB Wildlife station located 110 km from the hypocenter. The station is equipped with three-component strong-motion accelerometers at the surface and in boreholes at various depths and with pore pressure transducers located in a saturated, liquefiable layer. The recorded pore pressure and ground motion time histories both have frequency content that is a function of time. We have applied a wavelet decomposition technique to the El Mayor ground motion and pore pressure data, looking for a linear relationship between the signals. The analysis shows that the early P-wave accelerations (vertical component) initiate pore pressure response. However, the pore pressure records contain a low-frequency component that dominates the signal with no corresponding low-frequency component in the ground motion signals recorded near-by. Although uncommon, a similar behavior has been also reported in the literature for pore pressure signals recoded during the 1980 Mammoth Lakes, California, earthquake. We have extended this work to the analysis of 4 other seismic events that have induced an increase in pore pressure at WLA. As the response of pore pressure is potentially a local phenomenon, we have restricted our analysis to recordings from the same site. These events include the M5.8 Ocotillo

    Objetivo: la esclerosis lateral amiotrófica (ELA) es una enfermedad crónica, neurodegenerativa que genera malnutrición. El objetivo principal de este estudio es analizar el impacto de la malnutrición en el curso de la enfermedad y la sobrevida a largo plazo.Materiales y métodos: se realizó un análisis retrospectivo de 48 pacientes (22 mujeres [45.83%] y 26 hombres [54.17%], con un promedio de edad de 66,2 [43-83]) del 2008 al 2014. El análisis del estado nutricional inicial se midió utilizando el índice de  masa corporal (IMC), el estado nutricional de acuerdo al NRS 2002, la valoración global subjetiva (VGS) y la concentración sérica de albúmina. Los pacientes se dividieron en dos grupos, dependiendo del estado nutricional en el que se encontraban: bien nutridos o malnutridos. Los grupos se crearon por  separado, lo que permitió un análisis comparativo adicional de las técnicas utilizadas para la evaluación del estado nutricional.Resultados: un estado nutricional adecuado se relaciona con mayor sobreviva a largo plazo (456 vs. 679 días, NRS 312 vs. 659 vs. 835 días, IMC respectivamente: 41, 541, 631 días, resultados estadísticamente significativos para NRS e IMC). Las concentraciones de albúmina no fueron un factor pronóstico, pero se observó mayor sobrevida si las concentraciones de albúmina incrementaban durante el tratamiento nutricional.Conclusiones: el estado nutricional inicial y la respuesta positiva a la alimentación enteral están asociados a mayor sobrevida en pacientes con ELA, razón por la cual, la terapia nutricional debe de iniciarse lo antes posible.

    Los estudios llevados a cabo en la transición del hidrógeno neutro a λ~21-cm han contribuído a incrementar nuestro conocimiento acerca de las propiedades globales del medio interestelar, sea este galáctico o extragaláctico. Avances en este campo han sido provocados, a menudo, por la puesta en servicio de radiotelescopios que poseen una mayor resolución angular. Aquí se presenta una propuesta para desarrollar un nuevo instrumento, un interferómetro, que permitirá abrir nuevas líneas de investigación. Este instrumento combinará la técnica de síntesis de apertura con la de espectroscopía de correlación digital, para alcanzar una resolución angular de 1' y un campo de visión de ~1o.7.

    This article reports that in August 1986, under the direction of Mayor Raymond Flynn, the City of Boston initiated Phase I of a Traffic Relief Program (TRP). The program was an interagency effort of the Boston Transportation Department and the Boston Police Department, to provide increased enforcement of the city's traffic and parking regulations on congested roadways in downtown Boston. The TRP is a reaffirmation of the city's philosophy that major arterials' primary function is the movement of traffic during periods of heavy traffic flow. There were six objectives: to reduce vehicular travel time along travel corridors; to increase street/intersection capacity; to eliminate vehicular blockage at intersections; to eliminate double parking; to eliminate pedestrian/vehicular conflicts at intersections and thus reduce the potential number of accidents; and to provide clear regulatory and street name signage.

    Excerpts of speeches given at a public rally on World AIDS Day 1998 underscore the need to energize support for those living with HIV/AIDS, emphasize the importance of increasing public education efforts, and memorialize those lost to the disease. Reverend Pat Bumgardner stressed the need to educate children about practicing safe sex and the dangers of drug use. He also focused attention on AIDS as a worldwide crisis, with the 30 million people who have HIV or AIDS. Councilwoman Margarita Lopez spoke about achieving objectives and securing resources through activism. She also condemned New York City's Mayor for trying to hinder the rally. Anne Chelimsky, who did not speak at the rally but attended it, reflected on her new role as an activist, and on how the rally affected her. PMID:11367196

    Currently the SCEDC archives continuous and triggered data from nearly 5000 data channels from 425 SCSN recorded stations, processing and archiving an average of 12,000 earthquakes each year. The SCEDC provides public access to these earthquake parametric and waveform data through its website www.data.scec.org and through client applications such as STP and DHI. This poster will describe the most significant developments at the SCEDC in the past year. Updated hardware: ● The SCEDC has more than doubled its waveform file storage capacity by migrating to 2 TB disks. New data holdings: ● Waveform data: Beginning Jan 1, 2010 the SCEDC began continuously archiving all high-sample-rate strong-motion channels. All seismic channels recorded by SCSN are now continuously archived and available at SCEDC. ● Portable data from El Mayor Cucapah 7.2 sequence: Seismic waveforms from portable stations installed by researchers (contributed by Elizabeth Cochran, Jamie Steidl, and Octavio Lazaro-Mancilla) have been added to the archive and are accessible through STP either as continuous data or associated with events in the SCEDC earthquake catalog. This additional data will help SCSN analysts and researchers improve event locations from the sequence. ● Real time GPS solutions from El Mayor Cucapah 7.2 event: Three component 1Hz seismograms of California Real Time Network (CRTN) GPS stations, from the April 4, 2010, magnitude 7.2 El Mayor-Cucapah earthquake are available in SAC format at the SCEDC. These time series were created by Brendan Crowell, Yehuda Bock, the project PI, and Mindy Squibb at SOPAC using data from the CRTN. The El Mayor-Cucapah earthquake demonstrated definitively the power of real-time high-rate GPS data: they measure dynamic displacements directly, they do not clip and they are also able to detect the permanent (coseismic) surface deformation. ● Triggered data from the Quake Catcher Network (QCN) and Community Seismic Network (CSN): The SCEDC in

    The five letters by the Danish astronomer Tycho Brahe to the Görlitz astronomer, mayor, and reformer of the calendar Bartholomäus Scultetus are for the first time translated from Latin into German with comments. The letters of October 12, 1581, August 17, 1588, December 8, 1590, March 12, 1592, and Januar 7, 1600, which are to a certain extent very personal letters, deal with, among other items, Scultetus's manuscript on the comet of 1577 and offer interesting details regarding Brahe's observatories on the island Hveen and near Prague. In addition, they provide information on his projects of books, problems with paper and print, his pupil Paul Wittich, currently largely unknown correspondents and his friends in Saxony and Silesia. The author prefaces the letters with biographical information on the 16th century Görlitz astronomer.

    The Authors, after a short analysis on biomechanics of the elbow during throwing in baseball, show the movements of the elbow during the different phases of the throw and the stabilizing action of the ulnar collateral ligament, flexor-pronator muscles of the wrist, anconeus and brachial triceps muscles. Aim of this study is the evaluation of the peak torque, total work and average power of the flexor-extensor and pronator-supinator muscles of the elbows in professional baseball players. Isokinetic test data show that a mayor peak torque in flexo-extension at power and resistance test in the pitchers compared to the strikers. Whereas the strikers show a higher peak torque in pronation at the resistance test. This may happen because during a baseball match the ball is hit many times by the bat and the pronator muscle of the wrist are notably stimulated and reinforced. PMID:14509917
